Clinton v. Jones essays

Clinton v. Jones essays The basic idea that is raised in this case is separation of powers. To be more specific we can ask ourselves one question: Is the president of the United States of America immune to civil cases involving the personal life of the president? The two parties in the case Clinton v. Jones are William Jefferson Clinton and Paula Corbin Jones. William Clinton at the time of the incident was the governor of Arkansas. Paula Jones was an employee of the state of Arkansas. Jones claimed that Governor Clinton had made sexual advances toward her which she rejected. Following the continued rejection of Governor Clinton, Jones was punished by her supervisors. The case first went to District Court. In District Court, Clinton wanted to suspend the case totally on the grounds of Presidential Immunity. The judge declared that the case shall be put on hold until after Clinton finished his term. The case was appealed. At the Eighth Circuit Court of Appeals, the court agreed with district court but reversed its decision to postpone the case because it would be an unlawful use of Presidential Immunity. The case proceeded to the Supreme Court of the United States of America with one question: Is the president allowed immunity from civil cases in events that occurred before he or she took office? The United States of America during this time was in a state of awe as the Pathfinder landed on Mars, the comet Hale-Bob is seen, the Heavens Gate Massacre occurs, sheep are cloned, Mother Theresa dies, Princess Dianna is killed in a horrible car wreck, Taiwan is returned to China, there is peace in Chechnya, and Pol Pot finally goes on trial. The case came as a surprise to the world as all of these things were happening. The funny thing is that Paula Jones filed the case just before the deadline for filing a civil case was over. Across America, this case led to the investigation of President Clintons personal life by Kennet ...

Linear Regression Statistics and Analysis

Linear Regression Statistics and Analysis Linear regression is a statistical technique that is used to learn more about the relationship between an independent (predictor) variable and a dependent (criterion) variable. When you have more than one independent variable in your analysis, this is referred to as multiple linear regression. In general, regression allows the researcher to ask the general question â€Å"What is the best predictor of†¦?† For example, let say we were studying the causes of obesity, measured by body mass index (BMI). In particular, we wanted to see if the following variables were significant predictors of a person’s BMI: number of fast food meals eaten per week, number of hours of television watched per week, the number of minutes spent exercising per week, and parents’ BMI. Linear regression would be a good methodology for this analysis. The Regression Equation When you are conducting a regression analysis with one independent variable, the regression equation is Y a b*X where Y is the dependent variable, X is the independent variable, a is the constant (or intercept), and b is the slope of the regression line. For example, let’s say that GPA is best predicted by the regression equation 1 0.02*IQ. If a student had an IQ of 130, then, his or her GPA would be 3.6 (1 0.02*130 3.6). When you are conducting a regression analysis in which you have more than one independent variable, the regression equation is Y a b1*X1 b2*X2 †¦ bp*Xp. For example, if we wanted to include more variables to our GPA analysis, such as measures of motivation and self-discipline, we would use this equation. R-Square R-square, also known as the coefficient of determination, is a commonly used statistic to evaluate the model fit of a regression equation. That is, how good are all of your independent variables at predicting your dependent variable? The value of R-square ranges from 0.0 to 1.0 and can be multiplied by 100 to obtain a percentage of variance explained. For example, going back to our GPA regression equation with only one independent variable (IQ)†¦Let’s say that our R-square for the equation was 0.4. We could interpret this to mean that 40% of the variance in GPA is explained by IQ. If we then add our other two variables (motivation and self-discipline) and the R-square increases to 0.6, this means that IQ, motivation, and self-discipline together explain 60% of the variance in GPA scores. Regression analyses are typically done using statistical software, such as SPSS or SAS and so the R-square is calculated for you. Interpreting the Regression Coefficients (b) The b coefficients from the equations above represent the strength and direction of the relationship between the independent and dependent variables. If we look at the GPA and IQ equation, 1 0.02*130 3.6, 0.02 is the regression coefficient for the variable IQ. This tells us that the direction of the relationship is positive so that as IQ increases, GPA also increases. If the equation were 1 - 0.02*130 Y, then this would mean that the relationship between IQ and GPA was negative. Assumptions There are several assumptions about the data that must be met in order to conduct a linear regression analysis: Linearity: It is assumed that the relationship between the independent and dependent variables is linear. Though this assumption can never be fully confirmed, looking at a scatterplot of your variables can help make this determination. If a curvature in the relationship is present, you may consider transforming the variables or explicitly allowing for nonlinear components.Normality: It is assumed that the residuals of your variables are normally distributed. That is, the errors in the prediction of the value of Y (the dependent variable) are distributed in a way that approaches the normal curve. You can look at histograms or normal probability plots to inspect the distribution of your variables and their residual values.Independence: It is assumed that the errors in the prediction of the value of Y are all independent of one another (not correlated).Homoscedasticity: It is assumed that the variance around the regression line is the same for all values of the independent variables.

Natural Gas Plants Research Paper Example | Topics and Well Written Essays - 1250 words

Natural Gas Plants - Research Paper Example Natural gas is also known to be a necessity of this world. Gas in its pure form is of no particular use to the human beings but after being furnished in a Natural Gas Plant it can be used for several purposes. In some parts of the world it is used as a purpose of fuel and in some parts of the world it is used to light fire. Natural Gas Plants use different processes through which they can produce the sort of gas required by the individuals. It is seen that raw form of gas needs to pass through different stages to produce the productive gas. The processes respectively are known as Removal of Oil and Condensed particles, removal of water, separation of the gas liquids and lastly the removal of carbon dioxide and sulfur from the gas. Gas Plants use Low Temperature Separator, Liquid and Solid desiccant dehydrators, and Fractionators. This report would further revolve around Gas Processing Plants and would provide with further details about it. Natural Gas Plants use different devices to filter out the natural gas into productive forms. This report would revolve around the two main components of natural gas production which are Fractionators and Liquid and Solid Desiccant dehydrators. Both these components are used by almost all the gas plants to effectively produce the right form of gases. Fractionators use the different boiling points of hydrocarbons to their advantage whereas the dehydrators use different solutions which have the power to absorb and adsorb. The different processes in purifying gas would also be described in this report with emphasis on the two main components. This report would present with findings about the natural gas plants as a whole and not specifically about certain plants (Scott et al 1999) Gas in its pure form consists of many impurities which need to be filtered by the gas plants so that the gas can be used by the consumers.

Land Law terms and conditional Essay Example | Topics and Well Written Essays - 1500 words

Land Law terms and conditional - Essay Example The most common problems resulting from tenancy agreements border on landlord ignorance of tenant rights or problems of transfer as the one detailed in this case. This is a situation where a current owner sells the property to another, the major question being whether current tenants are bound by agreements made under the previous owner. Most times, the two forms of tenancy are referred to as either assured or shorthold tenancy. However, there are other forms of tenancy that result, not because they are assured or recognized by the law but because they fail to meet the provisions stated for these two forms of tenancy. A license to occupy A license to occupy is appropriate only for temporary arrangement; it is less detailed in comparison to a full lease. For this reason, it cannot be used in place of a full lease, or where the occupant is going to occupy property for a lengthy period of time. License to occupy is adaptable to diverse situations, and is frequently used when a tenant is only interested to occupy property momentarily or when the procedures of a lease are being concluded. Individuals wishing to occupy property for a temporary time can avoid such long term commitments by drafting a license to occupy, in which case rent is to be paid in the next week or month. If such obligations are not met, the License will come to an end. Under a License to occupy the Landlord has exclusive rights to property access at any time. Lease Agreement Unlike a license to occupy, a Commercial Lease Agreement is appropriate for letting property for a period not less than six moths and not beyond three years. The longer the lease period, the more detailed the lease agreement becomes. An agreement which is anything beyond three years requires a well detailed agreement which should be prepared and reviewed by a qualified solicitor. One major difference between leases and other forms of tenancy is that lease agreements accords exclusive rights of occupancy to the lease holder. The implication of this is that the landlord cannot access the property unless under any identified circumstances specified in the agreement. Exclusive rights to property also mean that the tenant reserves the right of the owner for the period of the lease, this means he can sub let, through a Sublease Agreement. Leasing is not common for residential property but is mostly embraced for commercial reasons. Lease forms a contractual obligation binding the property owner the lessee, however, it also creates an interest in property. For this reason, it must be issued for a definite period of time, but can extend beyond this period. In such a case, it becomes a Tenancy at Will which can be terminated through an adequate notice. Adequate time for the notice might be detailed in the lease agreement, however, if such is not included the notice period will equate to the frequency of payment of rent as indicated in the agreement. The main difference between a lease agreement and a License is that a lease conveys interest in land, something which a license does not. This was well indicated in a 1673 case, Thomas v Sorrell: In this case, it was passed that a license passes no interest, and does not alter or transfer property; all it does is make an act lawful which without the license had been unlawful. A similar, position was taken by Justice Macdonald in Baker v Gee, the Justice held; that according to the provisions of

Historical Modern Connections Essay Example for Free

Historical Modern Connections Essay Nature has always been looked at as an inspiration since beginning of time by all great artists and designers. Even in the current culture/era they have always looked back to historical arts and architectures for inspiration where they adapt, model, recycle and swipe arts. An Illustrated History of the Great Paris Designers and their Creations, New York 1972 Christian Dior He was a very influential fashion designer whom all designers respect and emulate. In 1930s after World War II fashion designer Dior concentrate on women fashions, with soft shoulders, wasp waists and flowing skirts which was appropriate for the post war era. The whole design idea came from his mother which was worn in 1900s. This design suited also the political agenda. He had private presentations until his market grew bigger for the â€Å"New look† designs he had designed (Kawamura 2004, 89). In 1948 Dior opened a ready to wear boutique, launched new perfumes, prior to the Bar Suits he had made in 1947. In 1949 he opened his Couture House managed by Civil Servant Jacques Rouet. In 1954 he unveiled new direction the French Bean line or Flat look, the New look Silhouette and Seamstress. Later in the year 1953 he discovered the Haule Couture autumn/winter, and in the year 1955-56 the Y Line dress, autumn/winter. (Kawamura 2004, 112) From the life and designs of Christian Dior we discover many of fashion designers nowadays are inspired by his life activities in design of great influence in the society. Alexander McQueen 1969  He had a delighted fashion and design audience with raw presentation depicting history and anarchic politics. He’s best known for his challenging and commendable designs which have solidified his status. In 1995 he designed autumn/winter catwalks-Highland Rape. In the year 1997 he designed autumn/winter lapoupee combines, aggressive tailoring and lyrical romantiom. He also designed men’s wear brand founded in the 19th Century and Military outfits (Quinn 2002, 132) He has always collaborated with others to make his designs best outfits. Application  From the two comparable designers Alexander McQueen and Christian Dior we find that art and design has always played a roll in the development of the human race. This is not only in small areas of our lives but in each and every aspect. For instance, spring/summer 2007 Christian Dior Kimono, non-western is inspired from the early 1800s through 1970s way back in the; Edo period 1603 to 1868, Meiji period 1868 to 1912, Taisho period 1912 to 1926, Shonwa period 1926 to 1989 which are currently sold in other names in the fashion industry (Kawamura 2004, 118)  Since the World War II. There have been great innovations in the fashion designs industry due to great creativity. Most of the fashion designs in the current market revolve around historical designs and changes made are to suit the changing lifestyles in our environment. Conclusion We all accept that from the times of Christian Dior, due to adaptability fashion designs has always become versatile and enlightening, hence history has always affected our present culture, and is more appealing. In fashion and design it’s an expression of life.

Courage in Little Women and Treasure Island Essay -- Literary Analysis

The dictionary definition of courage is bravery or boldness. In the set texts of Little Women and Treasure Island, courage is defined through the interaction of the characters, the situation and their reactions to it. Thus, there are different aspects of courage explored throughout the texts resulting in either in physical or psychological pain or a mixture to the characters. In this essay, I will analysis the method that each author employs to inform the reader of courage, discuss some aspects of courage explored in the texts and look at how courage differs between the genders. Alcott uses characterisation to display courage. She builds the characters over a period through their words, actions and appearance in conjunction with other characters comments and an omniscient authorial voice (Lukens, 2003). The character of Beth has a shy manner and timid voice, staying at home and who admits to being afraid of people. She is ‘dear’ to other characters and the author tells the reader her pet name is mouse. Yet this character shows courage by thanking Mr Laurence, who frightens her, for her piano causing Meg to exclaim that ‘the world is coming to an end’ (Little Women p.63) Alcott enhances this action through intertextuality to Pilgrims Progress where Mr Laurence is one of the biggest lions guarding the Palace Beautiful. Beth is the foil for the main protagonist, Jo for whom this behaviour is normal as evidence by her statement of Mr Laurence ‘I’m sure now that I shouldn’t be afraid of him’ (Little Women p.52 ). This illustrates that there are different levels of courage dependant on the characteristics of the character.

Attacking Wifi Nets with Traffic Injection

I am very much thankful to him. I benefited a lot discussing with him. I am also thankful to my parents who encouraged me and provided such a motivation, so I became able to perform this. I am also thankful to all my friends and those who helped me directly or indirectly in completion of my project. CONTENTS †¢Introduction †¢Crime Definition †¢Laws that have been violated †¢Possible Punishments (IT ACT + INTERNATIONAL LAWS) †¢Unlawful Losses and Gains †¢Working of Attacks †¢Description of Tools INTRODUCTION This term paper is based on â€Å"attacking wifi nets with traffic injection† also nown as packet injection which simply means the hacking of wireless networks with different techniques to send extra amount of traffic (packets, frames, duplicate copies) on a network by which a hacker can able to access the information and identity that a client is using. Some techniques are wireless network sniffing, DOS (denial of service attack), Man in the middle attack etc. Attacks on wireless LANs (WLAN’s) and wireless-enabled laptops are a quick and easy way for hackers to steal data and enter the corporate network.Many types of tools are used to perform hacking. Some of them are named as aircrack-ng, airjack etc. thts paper will later give brief information on tools used , working of tools ,losses and gains with hacking etc. These type of attacks are known as INTEGRITY attacks. Wireless networks broadcast their packets using radio frequency or optical wavelengths. A modern laptop computer can listen in. Worse, an attacker can manufacture new packets on the fly and persuade wireless stations to accept his packets as legitimate. We already know 802. 11 networks are weak.Open networks are prone to any well-known LAN perimeter attack WEP is vulnerable. Traffic injection has changed things like †¢Increased DoS (denial of service) capabilities †¢Dramatically decreased WEP cracking achievement time †¢Allows traf fic tampering †¢Allows stations attacks CRIME DEFINITION Cyber Crime –A crime where the computer is used as a tool or target. Cyber crime encompasses any criminal act dealing with computers and networks (called hacking). Additionally, cyber crime also includes traditional crimes conducted through the Internet.For example; hate crimes, telemarketing and Internet fraud, identity theft, and credit card account thefts are considered to be cyber crimes when the illegal activities are committed through the use of a computer and the Internet. Hacking – Traffic injection attacks comes under hacking. It is defined as whomever with the intent to cause or knowing that he is likely to cause wrongful loss or damage to the public or any person destroys or deletes or alters any information residing in a computer resource or diminishes its value or utility or affects it injuriously by any means, commits hacking.Hacking may also occur when a person willfully, knowingly, and withou t authorization or without reasonable grounds to believe that he or she has such authorization, destroys data, computer programs, or supporting documentation residing or existing internal or external to a computer, computer system, or computer network. Besides the destruction of such data, hacking may also be defined to include the disclosure, use or taking of the data commits an offense against intellectual property.This paper is a survey of wireless attack tools focusing on 802. 11 and Bluetooth. It includes attack tools for three major categories: confidentiality, integrity, and availability. Confidentiality attack tools focus on the content of the data and are best known for encryption cracking. Integrity attacks tools focus on the data in transmission and include frame insertion, man in the middle, and replay attacks. Finally, availability attack tools focus on Denial of Service (DoS) attacks. Law That Have Been ViolatedThe laws that have been violated are section 43,65 and 66 of IT ACT 2000. Section 43 of IT ACT 2000, defines as If any person without permission of the owner or any other person who is in charge of a computer, computer system or computer network, — (a) Accesses or secures access to such computer, computer system or computer Network; (b) Downloads, copies or extracts any data, computer data base or information from such computer, computer system or computer network including information or data held or stored in any removable storage medium; c) Introduces or causes to be introduced any computer contaminant or computer virus into any computer, computer system or computer network; (d) Damages or causes to be damaged any computer, computer system or computer network, data, computer data base or any other programs residing in such computer, computer system or computer network; (e) Disrupts or causes disruption of any computer, computer system or computer network; (f) Denies or causes the denial of access to any person authorized to acces s any computer, computer system or computer network by any means; g) Provides any assistance to any person to facilitate access to a computer, computer system or computer network in contravention of the provisions of this Act, rules or regulations made there under; (h) Charges the services availed of by a person to the account of another person by tampering with or manipulating any computer, computer system, or computer network, Section 65 of IT ACT 2000, defines as, Tampering with computer source documentsWhoever knowingly or intentionally conceals, destroys or alters or intentionally or knowingly causes another to conceal, destroy or alter any computer source code used for a computer, computer programs, computer system or computer network, when the computer source code is required to be kept or maintained by law for the time being in force, shall be punishable with imprisonment up to three years, or with fine which may extend up to two lakh rupees, or with both. Section 66 of IT A CT 2000, defines as, (1) Whoever with the intent to cause or knowing that he is likely to cause rongful loss or damage to the public or any person destroys or deletes or alters any information residing in a computer resource or diminishes its value or utility or affects it injuriously by any means, commits hacking. (2) Whoever commits hacking shall be punished with imprisonment up to three years, or with fine which may extend up to two lakh rupees, or with both. POSSIBLE PUNISHMENTS (IT ACT + International laws) Cyber crime is a type of crime that not only destroys the security system of a country but also its financial system. One supporter of legislation against cyber crime, Rep.Lamar Smith (R-Texas), stated, â€Å"Our mouse can be just as dangerous as a bullet or a bomb. † Cyber attackers should be penalized and punished severely and most cyber crimes have penalties reflecting the severity of the crime committed. Although in the past many laws against cyber crimes were ins ufficient, law enforcement agencies and governments have recently proposed many innovative plans for fighting cyber crimes. Punishment Cybercrime must be dealt with very seriously because it causes a lot of damage to businesses and the actual punishment should depend on the type of fraud used.The penalty for illegally accessing a computer system ranges from 6 months to 5 years. The penalty for the unofficial modification on a computer ranges from 5 to 10 years. Other penalties are listed below: Telecommunication service theft: The theft of telecommunication services is a very common theft and is punished with a heavy fine and imprisonment. Communications intercept crime: This is a Class-D crime which is followed by a severe punishment of 1 to 5 years of imprisonment with a fine.Other cyber crimes like telecommunication piracy, offensive material dissemination, and other cyber frauds also belong to this category. Information Technology Act-2000: According to this act, different penal ties are available for different crimes. Some of the penalties are as follows: Computer source document tampering: The person who changes the source code on the website or any computer program will get a punishment up to 3 years of imprisonment or fine. Computer hacking: The individual who hacks the computer or computer devices will get an imprisonment up to 3 years or a fine.Government protected system: An act of trying to gain access to a system which is a protected system by the government, will result in imprisonment for 10 years and a heavy fine. The introduction of such penalties have lead to a drastic reduction in the cyber crime rates as more and more criminals are becoming aware of the penalties related to them. Spreading the word about the penalties of cyber crime can serve as a deterrent against such crime. Penalties relating to cyber crime will vary depending on the country and legislation in place. Punishments according to IT ACT 2000The person who commits the crime sha ll be liable to pay damages by way of compensation not exceeding one crore rupees to the person so affected according to section 43 of IT ACT. The person who commits the crime shall be punishable with imprisonment up to three years, or with fine which may extend up to two lakh rupees, or with both according to section 65 of IT ACT. Whoever commits hacking shall be punished with imprisonment up to three years, or with fine which may extend up to two lakh rupees, or with both according to section 66 of IT ACT 2000 INTERNATIONAL LAWS In USA section 18 U. S. C.  § 1030 A) a fine under this title or imprisonment for not more than ten years, or both, in the case of an offense under subsection (a)(1) of this section which does not occur after a conviction for another offense under this section, or an attempt to commit an offense punishable under this subparagraph; and (B) a fine under this title or imprisonment for not more than twenty years, or both, in the case of an offense under subs ection (a)(1) of this section which occurs after a conviction for another offense under this section, or an attempt to commit an offense punishable under this subparagraph; In CanadaThe person who commits the crime is guilty of an indictable offence and liable to imprisonment for a term not exceeding ten years, or is guilty of an offence punishable on summary conviction. UNLAWFUL LOSSES AND GAINS Losses due to hacking Hackers targeted major companies including Sony, RSA Security, and Citigroup, but also governmental websites and smaller firms. Many companies could have prevented the attacks. Because of their vulnerabilities, they not only lost money, but also risked losing clients, prestige and market share. Multitudes of people were affected by their security breaches Recent reports showed hackers earned $12. billion in 2011, mainly by spamming, phishing, and online frauds. Some companies have made their financial losses public, while others chose not to disclose them. Here’ s a top 5 of the declared losses caused by hackings from last year until present. Undeclared losses may even exceed these ones. 1. $171 million – Sony Hacked in April to June 2011, Sony is by far the most famous recent security attack. After its Playstation network was shut down by LulzSec, Sony reportedly lost almost $171 million. The hack affected 77 million accounts and is still considered the worst gaming community data breach ever.Attackers stole valuable information: full names, logins, passwords, e-mails, home addresses, purchase history, and credit card numbers. 2. $2. 7 million – Citigroup Hacked in June 2011, Citigroup was not a difficult target for hackers. They exploited a basic online vulnerability and stole account information from 200,000 clients. Because of the hacking, Citigroup said it lost $2. 7 million. Just a few months before the attack, the company was affected by another security breach. It started at Epsilon, an email marketing provider for 2,5 00 large companies including Citigroup.Specialists estimated that the Epsilon breach affected millions of people and produced an overall $4 billion loss. 3. $2 million – Stratfor Last Christmas wasn’t so joyful for Stratfor Global Intelligence. Anonymous members hacked the US research group and published confidential information from 4,000 clients, threatening they could also give details about 90,000 credit card accounts. The hackers stated that Stratfor was â€Å"clueless†¦when it comes to database security†. According to the criminal complaint, the hack cost Stratfor $2 million. 4. $2 million – AT&T The US carrier was hacked last year, but said no account information was exposed.They said they warned one million customers about the security breach. Money stolen from the hacked business accounts was used by a group related to Al Qaeda to fund terrorist attacks in Asia. According to reports, refunding costumers cost AT&T almost $2 million. 5 . $1 million – Fidelity Investments, Scottrade, E*Trade, Charles Schwab The most recent declared losses were in a brokerage scam. A Russian national was charged in the US with $1. 4 million in computer and hacking crimes. $1 million was stolen from stock brokerages Fidelity Investments, Scottrade, E*Trade, and Charles Schwab.The rest of the money was taken from fraudulent tax refunds, with the stolen identities of more than 300 people. Gains To Hackers * To use your computer: * as an Internet Relay Chat (IRC) server – hackers wouldn't want to discuss openly about their activities on their ‘own' servers * as Storage for Illicit Material (ex. pirated software, pirated music, pornography, hacking tools etc) * as part of a DDoS Attack – where many computers are controlled by hackers in an attempt to cause resource starvation on a victim's computers or networks * To steal services and/or valuable files For thrill and excitement * To get even – maybe an I T staff who was terminated, or other parties you've ‘wronged' * As a publicity stunt – an example of which was reported in 1998 by Jim Hu in MTV â€Å"hack† backfires * Knowledge/Experiment/Ethical – some hackers probe a computer system to find its security vulnerabilities and then inform the system administrator to help improve their security * Another possible reason is that the hackers might suffer from a disease called Asperger syndrome (AS).They are people who are very good with numbers and at focusing on a problem for a very long period of time, but are not good in social relationships. How AS can possibly be linked to hacking behavior was discussed more thoroughly by M. J. Zuckerman in his ‘USA Today' article, What fuels the mind of a hacker? * Curiosity * To spy on friends, family members or even business rivals * Prestige – bragging rights in their social circle (particularly if they've hacked high-profile sites or systems) * Intellec tual Challenge Money – although most hackers are not motivated by financial gain; many professional criminals make money by using hacking techniques either to * set up fake e-commerce sites to collect credit card details * gain entry to servers that contain credit cards details * engage in other forms of credit card fraud WORKING OF ATTACKS Before studying about how traffic injection attacks works there are some basic terms we shoud have to know WEP Wired Equivalent Privacy (WEP) is a shared-secret key encryption system used to encrypt packets transmitted between a station and an AP.The WEP algorithm is intended to protect wireless communication from eavesdropping. A secondary function of WEP is to prevent unauthorized access to a wireless network. WEP encrypts the payload of data packets. Management and control frames are always transmitted in the clear. WEP uses the RC4 encryption algorithm. The shared-secret key is either 40 or 104 bits long. The key is chosen by the syste m administrator. This key must be shared among all the stations and the AP using mechanisms that are not specified in the IEEE 802. 11. FRAMES Both the station and AP radiate and gather 802. 1 frames as needed. The format of frames is illustrated below. Most of the frames contain IP packets. The other frames are for the management and control of the wireless connection. There are three classes of frames. The management frames establish and maintain communications. These are of Association request, Association response, Reassociation request, Reassociation response, Probe request, Probe response, Beacon, Announcement traffic indication message, Disassociation, Authentication, Deauthentication types. The SSID is part of several of the management frames.Management messages are always sent in the clear, even when link encryption (WEP or WPA) is used, so the SSID is visible to anyone who can intercept these frames. Authentication Authentication is the process of proving identity of a sta tion to another station or AP. In the open system authentication, all stations are authenticated without any checking. A station A sends an Authentication management frame that contains the identity of A, to station B. Station B replies with a frame that indicates recognition, addressed to A. In the closed network architecture, the stations must know the SSID of the AP in order to connect to the AP.The shared key authentication uses a standard challenge and response along with a shared secret key.

The higher the traffic of the network, the earlier we will be able to crack a WEP key with tools like aircrack-ng, airsnort, dwepcrack, weplab, WEPAttack, WEPCrack, etc. However, injecting traffic is not easy because you must build or capture a frame that causes a response frame in any other station (that is, a wireless node).This application carries out automatically all the needed actions to build a frame that causes a response in other station. These actions can be summarized in the following sequence of steps: 1. The application scans Wi-Fi networks and shows a list of WEP-protected networks, then it allows the user to select one of them. 2. It joins the selected network and moni tors that network in order to find a data frame. 3. It tries to extract a keystream prefix from the captured frame and then it tries to extend the keystream up to 40 bytes by means of the W.A. Arbaugh's inductive chosen plaintext attack. 4. It tries to find a host (for example, a connected computer, a network device, etc), which has an IP address belonging to a predefined range, by injecting forged ARP packets. 5. After finding an active host, it injects ARP packets targeted at that host. Some of the benefits of this application are easiness of use (due to its graphical interface, automatic operation, etc) androbustness (detection/management of network disconnections, repetition of failed actions, etc).Moreover, the Arbaugh's inductive attack can be performed by any Wi-Fi interface supporting injection in monitor mode, because the interface driver doesn't need any additional patch as it's usual to happen with the Bittau's fragmentation attack. Besides its higher applicability, this attack is generally more reliable than Chop-Chop attack for recovering a keystream of a given size, because it doesn't have to inject any frame larger than needed.

DESCRIPTION OF TOOLS The tools used for packet injection purposes are divided into two categories Hardware and software 1. Software Serious hackers usually use Linux-based open source penetration test tools from which to launch their attacks.This section details some of the more popular tools that can be used to search out and hack wifi networks. †¢Aircrack-ng: This suite of tools includes 802. 11 WEP and WPA-PSK key cracking programs that can capture wireless packets and recover keys once enough information been captured. Aircrack-ng supports newer techniques that make WEP cracking much faster. This software has been downloaded over 20,000 times. †¢Airjack: An 802. 11 packet injection tool, Airjack was originally used as a development tool to capture and inject or replay packets.In particular, Airjack can be used to inject forged deauthentication packets, a fundamental technique used in many denial-of-service and Man-in-the-Middle attacks. Repeatedly injecting deauthentication packets into a network wreaks havoc on the connections between wireless clients and access points. †¢AirSnort: AirSnort is wireless LAN (CLAN) tool which recovers WEP encryption keys. AirSnort works by passively monitoring transmissions, and then computing the encryption key when enough packets have been gathered.After that point, all data sent over the network can be decrypted into plain text using the cracked WEP key. †¢Cain ;amp; Able: This is a multi-purpose tool that can intercept network traffic, using information contained in those packets to crack encrypted passwords using dictionary, brute-force and cryptanalysis attack methods, record VoIP conversations, recover wireless network keys, and analyze routing protocols. Its main purpose is the simplified recovery of passwords and credentials. This software has been downloaded over 400,000 times. CommView for WiFi: This commercial product is designed for capturing and analyzing wifi network packets. C ommView for WiFi uses a wireless adapter to capture, decode, and analyze packets sent over a single channel. It allows hackers to view the list of network connections and vital IP statistics and examine individual packets. †¢ElcomSoft Wireless Security Auditor: This is an all-in-one cracking solution that automatically locates wireless networks, intercepts data packets, and uses cryptanalysis techniques to crack WPA/WPA2 PSKs.This software displays all available wireless networks, identified by channel number, AP MAC address, SSID, speed, load, and encryption parameters. While these capabilities can be found in open source tools, ElcomSoft provides a more polished product for professional use by wireless security auditors. †¢Ettercap: Ettercap can be used to perform man-in-the-middle attacks, sniff live connections, and filter intercepted packets on the fly. It includes many features for network and host analysis. This shareware has been downloaded nearly 800,000 times. Fi resheep: This is a plug-in to the Firefox browser that allows the hacker to capture SSL session cookies sent over any unencrypted network (like an open wifi network) and use them to possibly steal their owner’s identities. It is extremely common for websites to protect user passwords by encrypting the initial login with SSL, but then never encrypt anything else sent after login, which leaves the cookie (and the user) vulnerable to â€Å"sidejacking.† When a hacker uses Firesheep to grab these cookies, he may then use the SSL-authenticated session to access the user’s account. Hotspotter: Like KARMA, Hotspotter is another wireless attack tool that mimics any access point being searched for by nearby clients, and then dupes users into connecting to it instead. †¢IKECrack: This is an open source IPsec VPN authentication cracking tool which uses brute force attack methods to analyze captured Internet Key Exchange (IKE) packets to find valid VPN user identity an d secret key combinations. Once cracked, these credentials can be used to gain unauthorized access to an IPsec VPN. KARMA: This evil twin attack listens to nearby wireless clients to determine the name of the network they are searching for and then pretends to be that access point. Once a victim connects to a KARMA evil twin, this tool can be used to redirect web, FTP, and email requests to phone sites in order to steal logins and passwords. †¢Kismet: Kismet takes an intrusion detection approach to wireless security, and can be used to detect and analyze access points within radio range of the computer on which it is installed.This software reports SSIDs (Service Set Identifiers – used to distinguish one wireless network from another) advertised by nearby access points, whether or not the access point is using WEP, and the range of IP addresses being used by connected clients. †¢NetStumbler: This tool turns any WiFi-enabled Windows laptop into an 802. 11 network det ector. NetStumbler and dozens of similar â€Å"war driving† programs can be used with other attack tools to find and hack into discovered wifi networks. †¢WireShark: WireShark is a freeware LAN analyzer that can be used to passively capture 802. 11 packets being transmitted over a wifi network.This software has been downloaded millions of times. 2. Hardware †¢For hackers that prefer a turn-key package, there are also hardware wireless hacking tools available. We’ve highlighted one called WiFi Pineapple. It’s a simple, small, portable device that can be carried into any hotspot and used to attract any laptop trying to find a wifi access point. The Pineapple uses a technique called an Evil Twin attack. Hackers have used tools like KARMA to do the same thing for years, but with Pineapple, now you can buy a piece of hardware for only $100 that allows you to become a hacker without downloading or installing any software. Here’s what their website say s: â€Å"Of course all of the Internet traffic flowing through the pineapple such as e-mail, instant messages and browser sessions are easily viewed or even modified by the pineapple holder. †REFERENCES http://www. cse. wustl. edu/~jain//cse571-07/ftp/wireless_hacking/index. html http://www. cs. wright. edu/~pmateti/InternetSecurity/Lectures/WirelessHacks/Mateti-WirelessHacks. htm#_Toc77524642 http://www. webopedia. com/TERM/C/cyber_crime. html http://www. wi-fiplanet. com/tutorials/article. php/3568066 file:///C:/Users/jsk/Desktop/Wireless%20Hackers%20101. htm

Herd Health Surveillance And Management Health Essay

In 1907, the ‘British Royal Commission ‘ proved that childrens were at hazard from bovine TB ( 1 ) . Today this Zoonotic bTB ( caused by M. bovis ) is present worldwide. Tuberculosis, pulmonary tuberculosis, besides known as ‘Scrofula ‘ , is a menace to public wellness, domestic farm animal, wildlife, and besides to merchandise industry. The position of this disease as a re-emerging zoonotic disease is today of great concern ( 4 ) . The first instance of bovid infection from adult male to cattle was reported by Magnusson in 1937 ( 2, 3 ) . Bovine TB is now classified by OIE as a â€Å" List B † disease. States following the FAO and the OIE recommendation, seek to use appropriate and effectual control measures to halt the visual aspect of new instances of TB ( incidence ) ( 5, 23 ) . This can be hard to accomplish because the infective dosage could be a really low sum of B ( 22 ) .Low incidenceAs ‘incidence ‘ we understand the sum of new instances happening in a defined period of clip. The chance of developing a specific disease during a specified period of clip is the incidence rate. Incidence rate = new instances in specified period of clip ten factor ( 100,1000aˆÂ ¦ ) Entire population at hazard during the period ‘Low incidence ‘ ( LI ) occurs when new instances emerge in a lower and slower rate than before within a period of clip in the targeted population. Is this low incidence step existent and important adequate to province that bTB is under control and even taking to a possible obliteration? The reply is likely, No. Low incidence might non reflect the existent state of affairs on a national degree. Low incidence of bTB can propose that the disease is by and large non distributing fast, but has a changeless, slow tendency within the cattle population. The incidence could be higher in some portion of the state and really low in others. We need the ‘prevalence ‘ , in order to better understand how TB in a population could be quantified. ‘Prevalence ‘ is the entire figure of bing instances happening at one peculiar clip. : Prevalence = chronic conditions Diseases – count the entire figure of disease persons ‘Prevalence rate'A is the sum of the population who has a disease at a given clip. Prevalence rate = bing instances at the specified point of clip x factor Entire population at hazard during the period ( 15 ) In livestock the disease is profoundly predisposed by farming and managerial factors which are of highest importance. Environmental factors such as carnal carrying denseness, motion between groups, quarantine, the new stock, environmental fortunes ( humidness, temperature, air current, rain seasons ) , lodging, bedclothes, lacrimation, airing, sanitation and nutrient balance besides play critical portion. In diseases outbreaks in animate being groups, usually both clinical and sub clinical instances exist in the group ( Iceberg Concept ) . In those endemic diseases, more of the infections in a group have a sub clinical ( soundless ) presentation ( see figure ) . It is cardinal to place the status in the group in inquiry or the instance categorization ( negative, exposed, fishy, or reactor ) . ( 24 ) There is a group of states like Australia ( 30,31 ) , Poland and others, which has achieved free bTB position using strict methods of surveillance monitoring and control ( 23,41, Apx 1 ) . Others such as EEUU ( 27, 28, 29 ) and Spain, show by and large the moderate but uninterrupted decline of the disease ( 36 ) . Spain has improved the incidence rate. There has besides been a alteration in the prevalence rate of bTB among the carnal population ( 25 ) . This disease can be endemic. Prevalence / Incidence, of b.TB during 1986 – 2006 in Spain. PROGRAMA NACIONAL DE ERRADICACION DE TUBERCULOSIS BOVINA. ANOS 2008-2010.. ( 25 )Spain – a low incidence stateIn Spain the prevalence is higher in beef herds and engendering contending bulls ‘ herds than in dairy herds, which may be due to production related differences between these types of herds. Beef herds are kept under more extended conditions, which allow contacts with other herds and wildlife, via communal grazing land ( 4 ) . BTB presence in the wildlife species had been proven as a beginning of infection for house servants animate beings and a threat to endangered species ( 6,8 ) . It seems that species sharing the same ecosystems are conveying the disease. M. bovis has besides been detected in carcases of cervid, hare, wild Sus scrofa, Iberian lynx and fox found in studies of wildlife killed in national Parkss and private estates in cardinal, southern and west of the Iberian Peninsula ( 7, 4 ) . Figure1. Main bovid TB hazard factors classified into animate being, herd and region/country degrees. Worldwide bovine TB hazard factors Vet. Res. ( 2009 ) 40:50aˆÂ ¦aˆÂ ¦aˆÂ ¦aˆÂ ¦aˆÂ ¦aˆÂ ¦aˆÂ ¦aˆÂ ¦.. ( 4 ) Spain has a control programme in topographic point, at national and regional degree. Harmonizing to their informations about 97 % of the herds are free of bovine TB ( bTB ) ( 18 ) .This was achieved by the application of government trials and slaughter at the national degree. In the Central organisation there is the Ministry of environmental, rural and sea. On the regional degree there are official veterinary services with provincial and territory central offices ( 20,21 ) . REPORT OF THE â€Å" BOVINE TUBERCULOSIS † SUB-GROUP TASK FORCE, Spain, 14-15 November 2007 ( 18 ) Spain as a member province of the EU Commission has its ain Sub-group Task Force, which report back on the advancement of its bTB obliteration programme ( 18 ) . In order to command and forestall eruptions of bTB assorted signifiers of surveillance programmes have been established and information gathered and utilised from findings of these.What is disease surveillance?â€Å" Epidemiologic surveillance is defined as an experimental method based on uninterrupted entering to follow wellness position or hazard factors in a defined population, and peculiarly to observe the visual aspect of pathological procedures and analyze their development over clip and in infinite, with a position to following appropriate control measures â€Å" ( 19 ; Toma et al. , 1991 ) . Surveillance is defined as a ‘mechanism applied to roll up and construe informations on the wellness of carnal population, to accurately depict their wellness position with regard to specific diseases of concern ‘ ( 28 ) . The term surveillance is used for the acknowledgment of new or alien diseases, and monitoring is aimed at observing additions in established infection degrees that may signal the return of a disease eruption. Surveillance programmes are frequently used to integrate both surveillance and monitoring activities ( MOSS ) ( 28 ) .There are really clear definitions in the study of the ISVEE conference, held in Durban. ( 2009 ) Epidemiologic surveillance signifiers portion of descriptive epidemiology because it aims to supply a dependable image of the epidemiological state of affairs sing one or more diseases ( 13 ) . The construct of disease surveillance is shown in Figure 1. ( 26 ) .Surveillance methodsObligatory surveillance: Bovine TB is a countrywide programme disease which requires the declaration of all suspected bTB instances by husbandmans, veterinaries, abattoirs inspectors, and everybody in contact with farm animal. Everyday surveillance: Name inactive surveillance, besides known as ‘scanning ‘ surveillance, is an ongoing observation of the prevailing disease profile of a susceptible population. With the information from this information we can observe any unnatural alterations or emerging diseases and obtain a general image of the disease state of affairs. Active surveillance: Besides called tailored programmes, marks a specific disease or status within a defined population. The presence of the disease can be measured or its absence verified. At first a clear instance definition must be developed. Surveillance is so carried out in structured population-based reviews ( methodical proving at slaughter, random studies, scrutinies for infection in non-symptoms animate beings including wildlife ) or in structured mark surveillance actions ( disease coverage, aiming proving, ante-mortem reviews, research lab probes, lookout elements, field records, farm animal ‘s herds, wildlife disease statistics ) . â€Å" Effectives controls requires an apprehension of the epidemiology of a diseases, including its infections kineticss within house servants every bit good as wildlife populations † ( 32 chapter 8, p. 363 ) .Datas elementsDatas are obtained from different beginnings: Findingss in butcheries, in the field, in research research labs, menagerie, ferine animate being keepers, private veterinary patterns and from province veterinary surveillance. There are good definitions in the web of USDA. This site provides wide information on animate being health/disease countries ( 40 ) We can specify the informations by the event under surveillance. The event and the population at hazard ( numerator/denominator ) , have to be mensurable. Then we need to place the beginnings and the information suppliers, based in the appropriated nose count to obtain a existent position of the disease. Data aggregation is a squad undertaking, aggregators and suppliers and everybody else involved participate to accomplish the aims. It is based on hazard appraisal. To be good processs must be focused, systematic, efficient, dependable and economical. The end is to entree concealed pockets of an carnal population, to avoid uncontrolled state of affairss in the hereafter. The chief end here is the obliteration the bTB, and to derive the position of freedom of the disease. In disease surveillance, compulsory and voluntary presentments are common beginnings for informations aggregation. In distant countries with hapless substructure participatory assessments can be a valuable beginning of information. Labs play an of import portion for the proviso of valuable and dependable informations. An active and full functional diagnostic research lab service is hence cardinal for any surveillance activity. Analysis of information is besides performed by the research labs. Here we find two constructs to see, first esthesia, 2nd feasibleness. The threshold of esthesia must be the same in the full trial to hold consistence in the analytical procedure ; the targeted surveillance must be realistic and possible to execute.Once the information is validated it is fed into a centralized database for the entree and distribution to all stakeholders, usually by via an internet interface. The result must be clearly accessible for all parts involved. The usage of epidemiological informations can supply the rating of the disease and its effects. The cyberspace has become an of import tool for the decentralization of informations entry. Appropriate analysis of informations provides a good planetary representation of the state of affairs ( 11,14 ) . Geographic information systems GIS are used to back up this procedure ( 16 ) .Aims of national surveillanceTerbium is a notifiable disease worldwide. The OIE provides recommendations in its ‘Terrestrial Animal Health Code ‘ and all facets of surveillance are addressed and recommendations given to follow ( 17 ) .The purpose is to use a national surveillance, monitoring and control system which will help the obliteration of the disease. The chief aims for a national surveillance should be: To gauge the size of the job within the domestic and wildlife carnal population. To observe eruptions in animate beings both farmed and in wildlife population, monitor the class of such eruptions and measure the impact. To place bovid TB in the instance that it is brought to the state. To hold preventative controls and obliteration steps in topographic point on defined carnal populations to mensurate promotion and efficaciousness in the obliteration plan. To hold the capacity to verify disease freedom or low threshold of hazard for trading aims.DecisionBTB is a life endangering disease that affects animate beings and worlds likewise. Since its find attempts have been made to track it, to handle the disease and to command its spread with the purpose to finally eliminate it. Despite these attempts bTB is re- looking in an alarming manner amongst animate beings and worlds. Surveillance has become a cardinal component to avoid, proctor and halt the spread of the disease. Some states have been successful in cut downing and keeping its spread, or even eliminating it through effectual surveillance of their house servants and wildlife carnal population. The job is complex, broad stretch and clip consuming. It involves establishments, the husbandmans, the veterinarian services, the regional and governmental administrations ; even environmental factors play an of import portion. There is a demand to organize, on a regional degree every bit much as on a national one. Exchange of information and communicating is needfully combined to guarantee that information is processed and evaluated right, seasonably and used suitably ( 37 ) . Surveillance and effectual control programmes for bTB, adapted to the demands of each state and part, should be implemented and supported by regional, governmental and international organic structures, in a co-ordinated mode. Developing states frequently lack of the necessary installations, and hence need extra support from the developed universe to help their obliteration of this disease.

Allocation of Artificial and Transplantable Organs Essay Example

Allocation of Artificial and Transplantable Organs Essay Example Allocation of Artificial and Transplantable Organs Essay Allocation of Artificial and Transplantable Organs Essay Allocation of Artificial and Transplantable Organs Everyday many Americans and others across the world are in need of artificial organs, which is are man-made devices that are implanted into a person to replace their own natural organ and to perform the same functions as that natural organ would. The ability of this to succeed has been one of the biggest achievements in medicine and still continues to save the lives of people everywhere. However, this subject also brings up a lot of controversy. The main problem is that the supply of organs available is less than the great demand of patients needing them, therefore, here has to be way that decides how the organs will be distributed amongst the patients. There are many methods this can be done, but when doing so, one should not take into account a persons social worth and neither should they account for self-inflicted injuries. If it is taken into account, then it is not promoting Justice as fairness. Artificial organs began back in 1943, when a Dutch physician by the name of Willem Kolff invented the hemodialysis machine. This machine forced blood to and from the body for cleansing. Every time this was performed, it was required for the cannulas to be connected to arteries and veins. Eventually, these sites would become exhausted and could not work anymore. This resulted in the invention of a shunt by Dr. Belding Scribner, which is a tube permanently attached to one vein and one artery and allowed for the continuous blood flow. Now with the two inventions put together, the doctors had created an artificial kidney that could save many lives. However, this amazing breakthrough led to issue: the scarcity of these machines. Because there was very few of them available to patients, doctors had to come up with a way to decide which patients got dialysis and which didnt. The best option was The God Committee, created by the Swedish Hospital, Scribner, and Kings County Medical Society to take the burden of this moral decision off physicians. The committee consisted of seven members of the community: a surgeon, a minister, a housewife, a labor leader, a banker, a lawyer, and a state governmental official. They never met the candidates they were discussing, but had two physicians that served as advisors and screened the patients for medical unsuitability. The first criteria that was set by The God Committee required for patients wanting dialysis was that they ad to be residents of the state of Washington and under forty five years old. They also had to afford the expensive treatment. This was still not enough and too many people were applying so they then started considering the candidates personal information like education, employment, family, and achievements. Eventually, the committee in charge of distributing artificial organs was replaced by the United Network for Organ Sharing, or UNOS because of Congress passing the End-Stage Renal Disease Act stating that the federal government is entitled to pay for the dialysis treatment of any American. UNOS is a non-profit organization that established national standards of how the artificial organs are distributed and is still used in todays society. This organization mainly deals with national transplant waltlng llst ana matcnes Oonors wltn reclplents twenty-Tour nours a clay. UNOS was created in 1987, it seemed as if the system of allocating artificial organs had improved significantly, however, there are still many issues that have not been resolved. The main one being how and when applicants get put on the waiting list because UNOS does not deal with patients who are not yet on the list.

Hydroponics essays

Hydroponics essays Growing plants hydroponically is the method of growing plants in chemical solutions opposed to the traditional style of growing plants in soil. With the continual increase of industrialised society, large farm are becoming drastically less common and growing plants hydroponically is fast becoming one of the most popular methods of farming. When growing plants hydroponically they are easily monitored and any nutrition lacking can be seen and immediately added. In this experiment tomato plants were grown in several different solutions over a four week period in order to determine what nutrients plans need and why. There were nice different chemical solutions, these were Iron, -Magnesium, -Calcium, -Potassium, -Phosphorus, -Nitrogen and sulphur. Full nutrients and distilled water were also used to contrast the extremities of all nutrients and no nutrients. It is known that plants with an iron deficiency commonly have small leaves that do not remain green. These characteristics were apparent in the plants viewed as they had small yellow leaves. The plant in general looked considerably healthy with plant roots and stems reaching average lengths. The common trend of plants lacking sulphur is purple veins of lower leaf surfaces and petioles are commonly more vertical. These same results were apparent in the plants viewed however these characteristics did not appear until week four when the stems began to show a purple colour and the plants leafs strangely appeared to grow vertically up. The reason it did not show these characteristics until week four may have been because the plants had retained a fair amount of sulphur when originally in the soil to not become sulphur deficient immediately. Throughout the duration of the experiment sulphur deficient plants were considerably larger then most of the other plants viewed. ...

Coaching and aligning a team Term Paper Example | Topics and Well Written Essays - 500 words

Coaching and aligning a team - Term Paper Example This cooperation among team members can be enhanced further by the leadership of the team leader. For the time being, the Chairman must play the role of the team leader and must consider the fact that even when team members are intelligent or hard-working, each member has their own strengths and weaknesses. His experience and wisdom can ably guide the management team to work together. However, initially it can be a daunting task to ensure that each team member has left any previous experiences and biases behind so they can focus solely on the current situation. Katzenbach and Smith (1993), write in an article titled, The discipline of teams, note â€Å"When individuals approach a team situation, especially in a business setting, each has preexisting job assignments as well as strengths and weaknesses reflecting a variety of talents, backgrounds, personalities, and prejudices† (p. 168). This meant being very effective in coaching the management team to focus on their rolees and stay out of politics. The chairman must also learn how to listen to the members of the Board but he must be firm in emphasizing that they should not be involved in the operational aspects. Another advice that the Chairman of the Board can take is that he must employ his excellent interpersonal skills. This would mean being open, frank, or straightforward in his transactions with both management team and board members. It would be helpful to have good demeanor in communicating with the team since they are all professionals; however, as Chairman, he must speak out his mind to arrest the situation. He could start by having a personal briefing to each member ( both mgt, team and board members) so he can address the issues directly and succinctly. By doing so, he is evaluating the opinion of each person which can help him make his own decisions later. In short, he is consulting the people as a coach. Managers do appear to prefer medium by corresponding it to the richness of the

Psychoactive Substance use and Mental Health (Hong Kong) Essay

Psychoactive Substance use and Mental Health (Hong Kong) - Essay Example The semisynthetic derivatives in this group include hydromorphone, hydrocodone, oxymorphone, dihydrocodeine, oxycodone, and buprenorphine. The remaining two groups are synthetic chemicals such as the phenylpiperidines which include the meperidineas well as the fentanyl, and the pseudopiperidines which include methadone and propoxyphene (Havens et al 2007, 101). Heroine and morphine were used first as medicine in the 19th century and later used illicitly for recreational purposes. Previously, the dependence of heroin and other opioid drugs has proved difficult to counter successfully whereby the poor result has been accredited to environmental characteristics, patient characteristics as well as other powerful reinforcing effects of the same drugs. The most common problems of opioid abuse are known to be nausea and constipation. These two side effects have been found to be difficult to deal with especially for constipation. The concept of agoinist-replecement therapy was introduced approximately forty years ago representing a breakthrough in opiod drugs management especially heroin. Developments in training have encompassed newer pharmacotherapies, Narcotics Anonymous and the psychosocial therapy (Davids & Gastpar 2004, 210). These drugs tend to produce analgesia, mood changes, drowsiness as well as mental clouding but not all of these lead to loss of consciousness. Patients who report of pain claim that it is less intense and less discomforting which fades eventually after healing dosage of these drugs. Relief in pain is believed to be selective without affecting the other modalities of sense. Some patients are believed to experience euphoria. Vomiting, nausea, drowsiness, mental difficulties, apathy as well as the occurrence of decreased physical activities when given to pain free individual is common. The toxic effects and the subjective analgesic, which includes respiratory depression, may become more pronounced as the dose is
