Homeland Security Alert In Lax And Other State Airports Essay To overcome the increasing terrorists’ threats in most commercial airports many countries have boosted on their airports security both at home and abroad. Many countries especially Western have experienced many terrorist attack. This has forced them to invent on various alert measures to control these attacks mostly to their airports. Through Transportation Security Administration officers, Los Angeles have stepped forward to scrutiny their passengers and aeroplanes in their airport (Krikorian and Shogren, January 02, 2004). This action has been motivated by particular terror plot bringing about more concern on common remote control toys that are useful in denoting terrorists’ bombs. Aviation authorities in different countries have decided on carrying devices on carry-on bags. Passengers with remote control are subject to intense search. Remote control toys are the most devices used in lax and other airports. Air passengers face heightened security which is geared against possible grandiose terrorist attack. Los Angeles and other country’s government are doing everything to protect their country (Sauter and Carafano, 2005, p. 2). Transport Security Administration inspectors in airports in major cities like Los Angeles are emphasizing on passenger’s screening and their languages. There has been extra watchfulness with an appeal to Los Angeles and other nations not to forgo travel plans in their airports than other transports. There is need for alerts in airports; this should be done through air marshals especially on flights arriving from overseas and undercover observation around airports. Not only lax but also other airports have been on â€Å"Orange Alert† (Oldham, January 23, 2004). There are many places that competes Los Angeles in their potential targets both symbolic and substantial. For better protection against terrorism in airports the main prevention of the attack, always there should understand of the vulnerability that translates to threat. Co-coordinating of anti-terrorism efforts among local airports law enforcement agencies and Joint Terrorism Task Force has been adapted in Lax. They have tried as much as they can to plan and monitor means of preventing terrorism (Byman, 2008, p. 75). Cameras to monitor suspicious activity in airports with pilots completing terrorism awareness training have been adopted in most airports. All airport employees have been trained on security procedures with police increasing their patrol. Gas detection system has been improved to identify biological and chemical toxic. In airlines cockpit doors and locomotive doors has been adopted. There is also screening of passengers and their luggage. Los Angeles has identified potential facilities on terrorist attacks and established security plans. Different agencies through FBI, police departments and sheriff have teamed up to create Joint Regional Intelligence Center in which they can collect, share and analyze intelligence data on terrorism. More anti-chemical suits are required to protect airports from chemical attacks (Hutagalung, November 29, 2008). There is local law enforcement and fire agencies which uses different radio systems. Los Angeles has not established a comprehensive plan on evacuating large number of people in case of chemical or nuclear attack. There is computer software that records routine location and canine search at airports. Police offers data on possible terrorists’ targets and relative significance. These data is subject to change incase of security breach or suspicious activity (Oldham, January 23, 2004). Conclusion Like other airports, lax has been subject to federal rules mandating barriers perimeter around all facilities. A team for handling homeland security has been established incorporating different agencies. Improvement of security in communications, transportation and public infrastructure utilities have expanded ability of different countries in detecting and responding to terrorism. They have better trained those who are called on for first response in contaminated environment. Lax and other airports have tightened their security in response to terrorist. They have raised security alerts to the highest possible level as an indication that terrorist attack are coming up. Some measures are visible and others are not.

Coral Reefs Essay -- science

Coral Reefs Coral reefs are arguably the world’s most beautiful habitats. Coral reefs have been called the rainforests of the oceans, because of the rich diversity of life they support. Scientists have not yet finished counting the thousands of different species of plants and animals that use or live in the coral reef. There are three types of coral reefs: fringing reefs, barrier reefs, and atolls. Fringing reefs are located close to shore, separated from land by only shallow water. Barrier reefs lie farther offshore, separated from land by lagoons more than ten meters deep. Atolls, on the other hand, are formed far offshore and they make a ring-shaped reef that close a circular lagoon. Coral reefs are the largest biological structures on the planet, with the largest being the Great Barrier Reef covering over 2000 kilometers along the east coast of Australia (Focus, 1995). The reef is said to be 500,000 to 2,500,000 years old and is said to be visible from the moon.(Scientif! ic, 1987). There is only one problem with this beautiful structure and that is the carelessness of man. Silt from deforested lands and pollution from crowded coastlines choke them, and overuse by coal miners, fisheries, and even tourists deplete and destroy coral reefs. There are many more factors which add to the destruction of the coral reefs, which if not stopped it will destroy all coral reefs. Corals are animals, not plants, sunlight is the key to their survival. They need it to power the millions of microscopic algae, called zooxanthellae, that live in their tissues. The algae provides the corals with food and oxygen in return for raw materials and a secure place to live. This teamwork is what allows the reef to survive in nutrient-poor tropical seas. This relationship is sensitive to such changes in the environment as cloudy waters or extreme temperatures. The stress on the corals can cause them to expel their algae, a phenomenon known as bleaching(Futurists, 1993). With the algae gone, the coral skeleton is visible and eventually it dies. Died corals lead further on to the death of the reef. There are four environmental factors that effect their growth: temperature, salinity, water depth, and wave action. These factors exposes the reef to changes in the environment very easily especially since it is located so close to shore. This also makes it hard for all of... ...e to do something about saving these coral reefs. If these reefs are destroyed it is thought that it might destroy the entire ecosystem of the ocean. There are over sixty-five countries that have designated some 300 parks that include coral reefs as natural habitats in the world (Futurists,1993). The problem is that less that 30% of the designated areas are fully protected. The fight is economical not ecological. Such as Australia and the Caribbean who are making billions of dollars on their coral reefs. Everyone must work together to stop the pollution and the destruction of our coral reefs and our environment. it is not just one thing that is destroying the reefs! it is many factors together that are destroying it. Ultimately, it is as much a question of whether we save or destroy the planet as it is a question of whether we save or destroy the world’s reef.

Extracting Dna from Human Cheek Cells

The probable reason for the tinted brown shade in the human epithelial DNA and not the strawberry DNA is that human epithelial DNA is extracted from one's mouth in which there can be many germs that could change the color of the original DNA. Furthermore, in order to avoid these germs from affecting the human epithelial cell DNA greatly, the experimenter is only asked to rinse their mouth with distilled water while in truth, Just a rinse with distilled water does not eradicate all possible germs that could be living in one's cheek cells.However, some probably factors for why the strawberry DNA and the human epithelial DNA were so similar Is because both Dana were extracted using the same methods. For Instance, In both experiments detergent and ethanol were used to separate the DNA from the nucleus and proteins Inside the cells. Thus, although there are many differences and similarities between the strawberry and human epithelial DNA, in the end they both had the characteristic of bei ng standstill and clumpy. There were man's steps to this experiment.The major steps in this process of DNA extraction begin with rinsing the experimenter's mouth with plain water, then using a toothpick to scratch the inside of the cheek, and then rinsing the mouth again but this time with distilled water which is eventually spit into a cup. The reason this step is conducted is because it cleans the experimenter's mouth so that germs are limited from entering the cup and detaches the cells Inside the experimenter's cheek. Making them easily come out along with the spit Into the cup In the end.Once this step Is over, the spit In the cup is transferred to a test tube, ml of detergent solution Is added, and the test tubule Is mixed. The spit Is transferred to the test tube because it makes the spit easier handle. Furthermore ml of detergent, also called DEBT solution, is added to the test tubule to help break down the cellular and nuclear membranes of the cells in the spit, thus making the DNA more accessible. Finally, this new solution is mixed so that the DEBT solution is mixed well into the original spit and has caused almost all of the nuclear and cellular membranes to break down.Once these steps are over, ml of ethanol is added to the solution and after waiting for bout 3 to 5 minutes, the DNA can be extracted with an inoculating loop. The reason ethanol is added to this solution is because ethanol breaks the DNA apart from the other organelles inside the cell and does not allow the DNA to dissolve since DNA Is not soluble In alcohol. By not allowing the DNA to dissolve, after the 3 to 5 minutes wait, the DNA will automatically be visible near the top of the solution Inside the ethanol since the DNA can no longer mix with any of the other organelles.Thus, the wait is essential since it gives the DNA time to become visible and once it is, the e seen and touched by the experimenter. With this, the experiment is concluded and the experimenter can decide what th ey wish to do with their DNA. This procedure was effective in several ways. For example, the DEBT solution and the ethanol were extremely important to this experiment and were very effective in separating the DNA so that it was clearly visible towards the end. However, one way this experiment can be improved is by using plastic pliers to extract the DNA at the end of the experiment instead of the inoculating loop.This suggestion would be ore effective since with the inoculating loop there is a lower probability of extracting the DNA successfully than with the plastic pliers. This is because the DNA can slip out of the inoculating loop's loop while it is highly unlikely that the DNA will slip out of the plastic pliers grasp. Therefore, although this experiment was extremely effective, one adjustment that could be made is to replace the inoculating loop with plastic pliers. To conclude, there are many applications in the world where this experiment could be extremely important. One ex ample is law and crime.In court, Just as engineering can be an extremely useful tool in finding the true culprit, using the DNA found at the crime scene can be equally as important. This is because each person's DNA is unique and unlike anyone else's. This can quickly identify who the true culprit is in court and also be extremely helpful in the field of science and genetics as well. This is because DNA is the instructions to life and by studying this DNA, scientists and researchers can soon find ways to not only manipulate but enhance human life. Thus, it can be seen that this experiment can be useful in many different fields of study in today's society.

How Are They Recruited - 1534 Words

How are they recruited? Thompson (2013) viewed that people join Boko Haram out of boredom and the desire for an action packed adventure. They join in pursuit of an adventure viewed as a â€Å"just cause† but others may be motivated mainly by a desire to use their special skills e.g. bomb-making skills (Thompson 2013). Thompson explained that judging from evidences collected by the State Security Service, those who join Boko Haram are similar. For example, Habibu Bama is a dismissed soldier from Borno State and Kabiru Abubaka Dikko AKA Kabiru Sokoto also a dismissed soldier. According to Thompson (2012), violent encounters with security forces also, often serve as motivating factor for an already socially estranged person to join a terrorist group like Boko Haram (Thompson 2012), he threw more light on this point by saying Human Rights Watch researcher Eric Guttschuss analyzed Yusuf successfully attracted followers from unemployed youth by speaking out against police and political corruption. (Thompso n 2012, ) Terrorist groups also brain wash their recruits (Okemi 2013). Teaching them the violent ways of religion right from when they are young, for example kids were being taught to fight and die for the cause of Allah in the Arabic school Yusuf established in Yobe state (Okemi 2013, Babalola).
