Identifying Drugs of Abuse Using Gas Chromatography :: Forensic Science

Scenario On the 23rd of September 2015 at 22:58, Mr. Rob Slone was arrested on Sanctuary Road, West Bridgford on possession with intent to supply. A large amount of cash was found on the suspect and a bag containing unknown tablets and powders was recovered from the riverbank, in close proximity to the location of the arrest. A balance with off- white powder, an off- white powder in self sealed bag and a tablet in paper wraps were seized from Mr. Slone's property. At the riverside, a  £5 note, a tablet in paper wraps and 2 off- white powders in self sealed bags, were seized. Physical examination Aim The evidence is physically examined to determine the integrity of the seized substances before any destructive techniques are used. Introduction In forensic science physical examination of the evidence is essential as if the packaging is not correct evidence can be lost or accessed. A chain of custody is important Photography is essential, any photographs should be taken before the evidence is moved. Methods Exhibit MF/2 Before any destructive techniques were used on the exhibit, the integrity of the packaging was determined. The tamper evident bag containing the exhibit was examined to check if was correctly labelled and sealed. Upon receipt of the exhibit the continuity label was signed to ensure the integrity of the exhibit. The tamper evident bag was cut and opened. The yellow paper wrap containing the white tablet measured 1.8x 4cm. The yellow paper wrap was opened to remove the tablet. The exhibit MF/2 was photographed with scale. Visual examination indicates that the exhibit is a white tablet with a manufacturer’s logo CO/COD. The imprint suggested that the tablet could be co-codamol. Co-codamol The tablet was weighed in a plastic weighing boat to prevent any contamination. The tablet weighed 0.6001 grams. All the information was noted on a General Examination Record. Exhibit DR/3 Upon receipt of exhibit DR/3 the continuity label was signed. The tamper evident bag was cut and opened. In the bag there was an off white powder in a sealed bag. The bag containing off white powder was weighed. It weighed 0.80823 grams. Results and discussion Physical examination is essential for the integrity of exhibits. The exhibits must be physically examined before any techniques that would destroy are used. The exhibits The aim of the experiment as a forensic analyst is to examine the seized items visually before the presumptive tests. Exhibits Bag Number Samantha Naas DR/3 D10025448 MF/2 D10025224 Catherine Tuckey DR/2 D10025606 MF/3 D10025590 Lee Berry DR/1 D10025639 MF/4 D10025438 Presumptive tests Aim The presumptive tests are carried out to get a preliminary identification of the controlled sample and are used for qualitative analysis of the unknown substance.

North American Free Trade Agreement

The NAFTA agreement was signed in 1992, ratified in 1993 and implemented in 1994. It was designed to completely rescind trade barriers between these three nations. It had been surmised that this agreement would enhance employment due to increase in trade (North American Free Trade Agreement (NAFTA) , 1995).This agreement, which is second only to the European Economic Area in trade volumes, constitutes a single free trading zone for approximately three hundred and sixty – five million consumers of these three countries. It set aside import duties on a large number of goods that were exported from the US to Mexico and over a period of fourteen years, hoped to eliminate all tariffs. Subsequently, sections on affording protection to workers and the environment were included (Vogel, 2007).An agreement was reached between Canada, Mexico and the United States of America, whereby a free trade zone was to be created between these countries. This was termed as the North American Free Tr ade Agreement or the NAFTA. It has been instrumental in providing a platform for resolving trade related disputes amongst these nations. Furthermore, the NAFTA has actively taken up the safeguarding of intellectual property rights and compliance with the laws relating to the protection of such rights (North American Free Trade Agreement (NAFTA) , 2003).The NAFTA has engendered bitter and persistent opposition. A number of collective bargaining organizations have highlighted the fact that the prevalence of abundant and comparatively cheaper labor in Mexico has prompted several manufacturers to shift their operations to that country. The result of this relocation has been a drastic reduction of jobs in the US. However, opponents to this contention have argued that the free trade brought about by the NAFTA has generated more jobs than it has destroyed in the US (North American Free Trade Agreement (NAFTA) , 2002).There has been a marked increase in unemployment in the US. Moreover, the number of immigrants, both legal and illegal, into the US has depicted an unprecedented increase. The mass immigration of Mexicans is so grave that on many an occasion, they have risked their lives to enter the US. A meaningful decision regarding the various disputes besetting NAFTA has not been taken and it seems to have failed miserably (Tonelson, 2004).The consensus of most of the authentic reports has been that NAFTA has benefited only the transnational corporations. Workers, farmers and small businesses in Canada, Mexico and the US have uniformly been put to a huge loss. In addition, the environment has also sustained considerable damage due to this agreement. The health, safety and rights of labor in all three countries were badly compromised. However, there was a significant boost to the economy of the US and Mexico (Brown). Therefore, it can be stated, unequivocally, that the NAFTA, has by and large been a fiasco and the only beneficiaries have been the transnational corpor ations. â€Å"North American Free Trade Agreement (NAFTA).† The New Dictionary of Cultural Literacy, Houghton Mifflin. 2002.

How Is Romeo Presented in the First Two Acts of Romeo and Juliet

In the first two acts of Romeo and Juliet, Romeo is presented as a young, love struck man. He is a dreamer and a fantasist. The audience feels sympathetic towards him because love is taking him nowhere. In Act 1, we first meet Romeo as he is sobbing about his love for a young lady, who we later find out to be Rosaline. The first line he speaks, â€Å"Is the day so young?†, suggests that he is bored and waiting for something to happen as he is so shocked about how early it is in the day. To emphasise this, he goes on to say, â€Å"Ay me, sad hours seem so long†. Benvolio asks Romeo why he is sad and he explains that he is sad because he has no love and his line, â€Å"Out of here favour where I am in loves† shows that the person he loves does not love him. This is how the audience first learns of Romeo’s love struck ness. To show even more how love struck and sad Romeo is, he admits it to himself when he says, â€Å"This is not Romeo, he is some other where.† Benvolio asks him to â€Å"examine other beauties† to cure his love sickness. But Romeo says that if his eyes see anything more beautiful than Rosaline, then â€Å"turn tears to fires†. This shows that Romeo is very single-minded on Rosaline and believes that no one could be more beautiful than her. On the way to the Capulet’s party, Romeo is presented as upset and a spoil sport. He explains that he has a â€Å"soul of lead† which â€Å"stakes [him] to the ground [he] cannot move†. This shows that he is very serious about his love for Rosaline and feels his sadness as a heavy weight on him, not allowing him to have fun, but to grieve. Reluctantly, Romeo agrees to go to the party in the hope that he will find Rosaline. At the Capulet’s party, Romeo finds another girl, Juliet, and is entranced by her beauty. He asks himself, â€Å"Did my heart love till now?†. This line suggests that he completely falls in love with Juliet and asks himself whether he did love Rosaline or whether he had just got it into his head. This shows that Romeo was very single-minded and a sudden link is made between him and Juliet. However, as Romeo is so absorbed by Juliet he looses his disguise. When Tybalt, a keen Capulet, finds out about this and becomes very angry, describing Romeo as a â€Å"villain Montague† because he has gate crashed the Capulet’s party. This shows that Tybalt is an enthusiastic Capulet and believes Romeo is of the opposite being. But Capulet himself is in a very jolly mood and he describes Romeo as a â€Å"portly gentlemen† and a â€Å"well-governed youth†, showing that Capulet’s beliefs of Romeo is that he is a dignified and well behaved young man. Romeo is also described as a handsome and gentle young man. This is shown in Act 2, as the Nurse described Romeo as â€Å"his face be better than any man’s† and â€Å"gentle as a lamb†. This shows that there are different views of Romeo from different characters but, in general, Romeo is presented as a young, handsome and brave young man who is a distant part of his feud-orientated family. As soon as Romeo falls in love with Juliet a sudden link is made between them. The way they speak is very poetic and in verse, as if they know exactly what to say next. Also, Romeo is presented as religious when he compares his lips to â€Å"two blushing pilgrims†. Romeo is presented as a quite sensible young man and, unlike Benvolio and Mercutio, he doesn’t joke about and mess around. He also doesn’t seem to be part of the dispute between the Capulet’s and Montague’s, showing how keen his is on love. On the other hand, as soon as Romeo and Juliet fall in love they become trapped in their own world and don’t mention much about their families being enemies. Romeo sometimes risks his life and many consequences in order to see Juliet, showing how much he truly loves her. Romeo is also presented as a risky and completely taken in man. At the end of Act 2, Romeo agrees to marry Juliet, but neither the Capulet’s nor Montague’s no about it. This is very risky for Romeo and Juliet and Romeo seems to dismiss the consequences because he is so taken in by Juliet. To make things even more secretive, Romeo arranges for a rope ladder to be sent to the excited Nurse, so that Romeo can climb into Juliet’s room to get married. In conclusion, Acts 1 and 2 of Romeo and Juliet presents Romeo as, at first, a fantasists and love struck man. By the end of Act 2, he is seen as a very entranced and risky man, showing his devotion of love towards Juliet.

Annotated Bibliography on Technology

Annotated Bibliography on Technology Annotated Bibliography on Database Forensics: Data base forensic has various aspects including its process, weaknesses and disadvantages. This research paper aims at explaining the process of data base forensic, its related weaknesses and disadvantages. This is to certify whether the use of database forensics tools will keep the confidentially of the data or not. In the first instance, data base forensic has a unique process in which it is carried out. This shows that data base process has to be enacted so that facts are investigated and established. Rogers, M. (2003). The role of criminal profiling in the computer forensics process. New York. The author of this source document tries to disclose to people that there is a significant role in criminal profiling in computer forensic process. This role is most useful in computer forensic process where information of criminals is stored. He clearly and precisely impacts that knowledge into every reader of his work to make the role understood by many individuals. From the source document, we get to know that criminal profiling involves getting all the required data from criminals for proper investigations and establishment of factual information in criminal and civil courts. Criminal profiling serves a critical purpose since it keeps all information of criminals making it easy to track them even if they escape. Criminal profiling also serves to indicate that certain individuals are criminals. It includes the crime and felony committed by the criminal at hand. This source is useful in to those individuals entrusted with criminology duties. It makes them aware that criminal profiling is necessary for proper management of criminals. It also serves to show that full data and information of criminals should be taken for effective investigation and establishment of factual information concerning criminals. Werrett, J, D. (2000). The National DNA Database. Birmingham: UK. Database forensic puts into action many ways to get criminals. The data base forensic process used may involve many ways of getting the criminals. One of the methods enacted is the DNA testing operation. For the last two years, the Forensic Science Service has established and put into operation a National DNA Database. This operation is meant get criminals who escape after committing their felonies. The data base forensic process involved testing DNA samples of suspected individuals of various crimes. Also, samples were analyzed from stains from gotten from scenes of crime. This shows that the stains were to be analyzed to get the criminal who committed the offense. DNA samples of suspected individuals were tested to prove whether or not they committed the crime they are being suspected of committing. This source will be useful to those individuals who may be suspecting criminals for committing certain crimes. This is because their DNA samples can be analyzed to prove guilty or innocent of the suspected felonies. Gill, P, Curran, J, Elliot, K. (2005). A graphical simulation model of the entire DNA process associated with the analysis of short tandem repeat loci. USA. Database forensic process that deals with DNA analysis provides complete information to DNA and its related tests to arrest criminals. The author of this journal article shows us that there is a prevalent increase in the use of expert system in interpretation of short tandem DNA profiles. It has been proved that this way of getting data from criminal is cumbersome and time-consuming hence invention of the graphical model. This is reference to the Low Copy Number (LCN) applications. The graphical model is used to simulate stochastic variations related to DNA process. From the model, DNA process starts with extraction of sample followed by the preparation of a PCR reaction mixture. This shows that database forensic is becoming complex but faster in DNA process to get information regarding to criminals. This source will, therefore, be useful to those intellectual individuals dealing with criminal investigations. This source document clearly provides a complex but faster way of DNA process to get information from criminals. Willuweit, S. (2007). Y chromosome haplotype reference database (YHRD): Update. Berlin: Germany. This source document shows that Y chromosome haplotype reference database (YHRD): Update is an application of database forensic process. The update is designed for forensic analysts in their work since it is meant to store the Y chromosome haplotypes from global population. This update is mainly useful to those individuals who are interested in family and historic genetics. Since genetics is the scientific study of passage of genetic materials form parents to their offsprings, forensic analysts get to know genetic characteristics of various families. This knowledge can be used to trap criminals since their family genetic characteristics are known. Forensic analysts understand families with law breakers hence they fall suspects of crimes which happen within their reach. This source document will be useful since it gives people a clear knowledge about the Y chromosome haplotype reference database (YHRD) update. It also makes people know that family genetics can be useful in tracking criminals. Rowlingson, R. A Ten Step Process for Forensic Readiness. University of Aston: Birmingham. This research paper gives a ten step process which an individual should undergo to be for database forensic process. The ten processes outlined in the source document are as follows; define business scenario that require digital evidence, identify available resources and different types of evidence, determine the evidence collection requirement, and establish a capability for securely gathering legally admissible evidence to meet the requirement and establish a policy for secure storage and handling of potential evidence. Other steps include ensuring that monitoring and auditing is targeted to detect and deter major incidents, specifying circumstances when escalation to a full formal investigation is required, training staff, presenting an evidence-based case describing the incident and its impact, and ensuring legal review to facilitate action in response to the incident. The source document is useful since it gives researchers the ten step process for data base forensic readiness. This serves to prepare and make it known to individuals joining CID that they have to be prepared to be ready for data base forensic process. Bandelt, H, J, Lahermo, P, Richards, M V. Macaulay, V. (2001). Detecting errors in mtDNA data by phylogenetic analysis. UK. The author of this source document claims that some errors may occur on a forensic mtDNA data base. This error may result in wrong establishment of facts concerning criminals. This error may also lead to passing out wrong judgment to suspected criminals. This implies that innocent suspected criminals may be declared guilty while guilty suspected criminals may be declared innocent. This shows that the error has great effect on the judgment passed on criminals. This source document comes up with a way in which the error on a forensic mtDNA data base can be detected to avoid confusion. This source document will be useful since it gives a way in which the mtDNA error can be detected to avoid confusion and wrong judgment in criminal and civil courts. Researchers and readers can clearly understand the error and the way of detecting it. There are some weaknesses related to database forensic and its related tools. These weaknesses serve to draw back the efforts put in place, by the use of data base forensic, to investigate or establish facts in courts. The weaknesses bring about limitations to the use of forensic data base in investigating and establishing facts in courts. Lee, S, Kim, H, Lee, Lim, J. (2005). Digital evidence collection process in integrity and memory information gathering. Korea University Seoul. South Korea. The author of this source document brings out a weakness that is linked to data base forensic. The weakness is related to the EnCase that was used globally. Its weakness is that modifications can be made on MDC value of digital evidence. This shows that the MDC value is not standard hence can be adjusted resulting to resulting to errors. This led to the proposal of another counter measure. The counter measure proposed was the MDC public system, public authentication system with PKI and MAC system. This source document is useful since it brings out the weakness of the MDC value and its counter measure proposal. Leigland, R W. Krings, W. (2004). A Formalization of Digital Forensics. France. This source document brings out one of the weakness in data base forensic. The weakness limits investigation and some other ways of finding evidence against criminals. The weakness stated in this source document is the unclear use and bounds of digital evidence in legal proceedings. This means that the current techniques, of digital cameras, may not rigorous enough to be used in the courtroom. This limits evidence that is presented against criminals if recorded by digital devices such as digital cameras. This source is helpful since it makes clear the weaknesses of data base forensic. Digital evidence may not be allowed during legal proceedings in courtrooms. Harris, R. (2006). Arriving at an anti-forensics consensus: Examining how to define and control the anti-forensics problem. Purdue University: USA. According to this source document, there are some anti-forensics problems that act as draw backs to data base forensic. Such problems are some of the weaknesses of data base forensic in investigating and establishing facts concerning criminals. This source is helpful since it shows that anti-forensic problems act as weaknesses of data base forensic. Newsham, T, Palmer, C, Stamos, A Burns, J. (2007). Breaking Forensics Software: Weaknesses in Critical Evidence Collection. San Francisco: USA. According to this source, forensic software break down is a common problem. Such breakdown brings about problems in collection of information to be used as evidence. This results in weakness in critical evidence collection. Casey, E. (2003). Network traffic as a source of evidence: tool strengths, weaknesses, and future needs. Knowledge Solutions LLC: USA. The author of this source document mainly focuses on weakness brought about in data base forensic by tools of data base forensic. Since the tools used are not100% effective, they are prone to errors. These errors make data base forensic a defective way of investigating and establishing facts about criminals in criminal and civil courts. This source is, therefore, useful as it informs researchers of the weakness brought in data base forensic b y defective tools used. Thompson, E. (2005). MD5 collisions and the impact on computer forensics. West Lindon: United States of America. Thompson concentrates his writing on the weakness of data base forensic caused by MD5 collisions. These MD5 collisions have an impact on data base forensic since it brings about weaknesses in the MD5 hash algorithm. This leads to the general weakness of data base forensic as a process of investigating and establishing facts on criminals in courts. This source document is useful as it grants researchers and readers the chance to discover that MD5 collisions results in weakness of the data base forensic. Inclusively, there are some disadvantages that come about due to the use of database forensic tools. Nagesh, A. (2006). Distributed Network Forensics using JADE Mobile Agent Framework. Arizona State University: USA. Nagesh says that some disadvantages of data base forensic are brought about by architectures in data base forensic. This is because the architectures create network congestion near the forensics. This leads to unavailability of network in such places. Data base forensic tools and devices which use network cannot operate properly in such places due to lack of network. This interferes with collection of data and information to be used as evidence. This source is helpful since it makes researchers and readers be aware of the disadvantage caused by data base forensic architectures. Haggerty, J, Jones, D, L Taylor, M. (2008). Forweb: file fingerprinting for automated network forensics investigations. Liverpool John Moores University: UK. This source admits that there are many disadvantages connected to data base forensic. This is because some ways of data base forensic make use of approaches that use computationally exhaustive statistical measures. Some of these measures are complex in nature posing a problem in proper establishment and investigation of information to be used as evidence. The source is useful since it clearly shows that file printing for automated network forensic investigations may be intensive hence a predicament in data and information collection. Navarro, P, J, Nickless, B Winkle, L. (1995). Combining Cisco Net Flow Exports with Relational Database Technology for Usage Statistics, Intrusion Detection, and Network Forensics. The author of this source document suggests that some of the disadvantages of data base forensic are caused by the tools used. This means that any defective tool used in data base forensic process results in one or more problems. According to her, data can be lost if the back-end SQL data base is unavailable. This implies that the lack of the back-end SQL data base results to data loss. This source is useful since it equips it readers that data will be lost if the back-end SQL data base is unavailable. Singhal, A Jajodia, S. (2006). Data warehousing and data mining techniques for intrusion detection systems. Gaithersburg: USA. The disadvantage of data base forensic explained in this source document bases on data mining and data warehousing techniques. These techniques improve performance of Usability of Intrusion Detection System (IDS). The problem comes with the current IDS since they do not provide support for historical data summarization and analysis. This means that data collected is not supported hence does not have assurance of being true or false. This source document is useful in its full content of the problem caused by the current Usability of Intrusion Detection Systems. Garfinkel, S, L. (2010). Digital forensics research: The next 10 years. Monterey: USA. The golden age of computer forensic is quickly coming to an end. This calls for careful handling of data base forensic tools. SQL, for example, requires a standardized careful planning for its handling. This means that some of data base tools are delicate and vulnerable hence requires careful handling. Careless handling of such tools may result in their damage hence loss. This source document is useful since it precisely explains the idea careful planning for data base forensic tools such as the SQL data base.

History and Geography of Puerto Rico

History and Geography of Puerto Rico Puerto Rico is the easternmost island of the Greater Antilles in the Caribbean Sea, approximately a thousand miles southeast of Florida and just east of the Dominican Republic and west of the U.S. Virgin Islands. The island is approximately 90 miles wide in an east-west direction and 30 miles wide between the north and south coasts. Larger Than Delaware and Rhode Island Puerto Rico is a territory of the United States but if it became a state, Puerto Ricos land area of 3,435 square miles (8,897 km2) would make it the 49th largest state (larger than Delaware and Rhode Island). The coasts of tropical Puerto Rico are flat but most of the interior is mountainous. The tallest mountain is in the center of the island, Cerro de Punta, which is 4,389 feet high (1338 meters). About eight percent of the land is arable for agriculture. Droughts and hurricanes are the major natural hazards. Four Million Puerto Ricans There are almost four million Puerto Ricans, which would make the island the 23rd most populous state (between Alabama and Kentucky). San Juan, Puerto Ricos capital, is located on the north side of the island. The islands population is quite dense, with about 1100 people per square mile (427 people per square kilometer). The Primary Language Is Spanish Spanish is the primary language on the island and for a short time earlier this decade, it was the commonwealths official language. While most Puerto Ricans speak some English, only about a quarter of the population is fully bilingual. The population is a mixture of Spanish, African, and indigenous heritage. About seven-eighths of Puerto Ricans are Roman Catholic and literacy is about 90%. The Arawakan people settled the island around the ninth century CE. In 1493, Christopher Columbus discovered the island and claimed it for Spain. Puerto Rico, which means rich port in Spanish, wasnt settled until 1508 when Ponce de Leon founded a town near present-day San Juan. Puerto Rico remained a Spanish colony for more than four centuries until the United States defeated Spain in the Spanish-American war in 1898 and occupied the island. The Economy Until the middle of the twentieth century, the island was one of the poorest in the Caribbean. In 1948 the U.S. government began Operation Bootstrap which infused millions of dollars into the Puerto Rican economy and made it one of the wealthiest. United States firms that are located in Puerto Rico receive tax incentives to encourage investments. Major exports include pharmaceuticals, electronics, apparel, sugarcane, and coffee. The U.S. is the major trading partner, 86% of exports are sent to the U.S. and 69% of imports come from the fifty states. United States Citizens Since 1917 Puerto Ricans have been citizens of the United States since a law was passed in 1917. Even though they are citizens, Puerto Ricans pay no federal income tax and they can not vote for president. Unrestricted U.S. migration of Puerto Ricans has made New York City the one place with the most Puerto Ricans anywhere in the world (over one million). Pursuing Statehood Through the U.S. Congress In 1967, 1993, and 1998 the citizens of the island voted to maintain the status quo. In November 2012, Puerto Ricans voted not to maintain the status quo and to pursue statehood through the U.S. Congress. 10-Year Transitional Process If Puerto Rico were to become the fifty-first state, the U.S. federal government and the state-to-be will establish a ten-year transitional process towards statehood. The federal government is expected to spend about three billion dollars annually in the state toward benefits not currently received by the Commonwealth. Puerto Ricans would also begin paying federal income tax and business would lose the special tax exemptions that are a major part of the economy. The new state would probably obtain six new voting members of the House of Representatives and of course, two Senators. The stars on the United States flag would change for the first time in more than fifty years. If independence were chosen by the citizens of Puerto Rico in the future, then the United States will assist the new country through a decade-long transition period. International recognition would come quickly for the new nation, which would have to develop its own defense and a new government. However, for now, Puerto Rico remains a territory of the United States, with all that such a relationship entails.

Countable and Uncountable Nouns for Beginners

Clostridium tetani - Essay Example The author has rightly presented that Clostridium tetani is obligate anaerobe and doesn’t grow in the presence of oxygen. Optimal conditions for growing this bacterium are temperature of 37 degrees Celsius, with PH of 7.4. It grows on different nutrient media including agar enriched with blood. When cultivated on agar enriched with blood it manifests alpha hemolisis, but with prolonged cultivation it produces beta hemolisis. Because Clostridium tetani is mobile bacteria and has flagella when cultivated produces the effect of swarming and tends to spread over the complete area of the culture. When cultivated produces very thin and see-through layer of bacteria that is very hard to notice with a naked eye, except on the edges of the colonies. It is difficult to obtain a pure culture of Clostridium tetani, this is why method called Fildes technique is often used, when the bacteria is inoculated on a small area on an agar plate and after incubation of 10 hours another subcultures are made from the edge of the swarming area that is constituted mostly of Clostridium Tetani. In suboptimal conditions, Clostridium tetani forms spores that are relatively resistant. Spores are killed in boiling water for 10-15 minutes, and in the moist heat of 121 degrees Celsius after 20 minutes. Based on the agglutination process Clostridium Tetani is classified in 10 serological types (only type IV doesn’t have flagella and is not mobile).... It is protein based molecule with molecular weight of 150 kDa (Kilo Daltons) and is constitutes of two parts, heavier or B chain with weight of approximately 100 kDa and lighter A chain with molecular weight of 50 kDa. Heavier B chain of this toxin bonds to the cell membrane and helps chain A to enter the cytosol of the cell (Farrar et al. 2000). The A chain than migrates through the axons to the central nervous system. Lighter A chain of the tetanospazmin toxin in the CNS impairs the release of inhibitory neurotransmitters in the brain (GABA-gamma aminobuteric acid and glycine) by degrading protein called synaptobrevin (small membrane based protein). Consequence of this effect is hyperactivity of the skeletal muscles in the body and development of muscle contractions and muscle spasm (Schiavo et al. 1992). Infection with C Tetani may cause development of condition called tetanus. It is disease that is characterized by presence of generalized spasms of the skeletal muscles in the bod y that is produced by the tetanospasmin toxin. It is caused when a wound is contaminated with spores of Clostridium Tetani. C Tetani are widespread bacteria that are present in the soil, dust, manure of domestic animals, our clothing and in about 20 percents of human gastrointestinal tract (Bleck 1995). If the wound is deep enough spores of C. tetani in anaerobic conditions can develop in viable bacteria that start to release toxins. Toxins are released when the bacteria are destroyed and bacterial cytosol along with toxins is released into the human tissues. Incubation period between the infection and occurrence of first symptoms ranges between 3 and 21 days, but that depends mostly on the site of primary infection. As early sign patients may report dysphagia and sore throat and some
