Answer:
pollution control, in environmental engineering, any of a variety of means employed to limit damage done to the environment by the discharge of harmful substances and energies. Specific means of pollution control might include refuse disposal systems such as sanitary landfills, emission control systems for automobiles, sedimentation tanks in sewerage systems, the electrostatic precipitation of impurities from industrial gas, or the practice of recycling. For full treatment of major areas of pollution control, see air pollution control, wastewater treatment, solid-waste management, and hazardous-waste management.

Next to the conservation of species from the loss of biological diversity, the control of pollution is the conservation problem of greatest magnitude; it might even be argued that pollution control is more urgent and important. Ultimately, the control of pollution involves a number of social decisions: 1) not to allow the escape into the environment of substances or forms of energy that are harmful to life, 2) to contain and recycle those substances that could be harmful if released into the environment in excessive quantities, and 3) not to release into the environment substances that persist and are toxic to living things. The knowledge and technology needed to put these decisions to work are now available. Pollution control does not mean an abandonment of existing productive human activities but their reordering so as to guarantee that their side effects do not outweigh their advantages.
However, for economic reasons, none of these measures is applied universally, and political and social pressures have not yet forced their application. Developing countries have expressed fear that excessive concern over pollution could impede their economic development—and indeed some of these countries have become sanctuaries for industries that find it less expensive to operate there than in areas with more rigorous standards. It is apparent that pollution control, regardless of the advanced state of its technology, will become a reality only when people demand it and only when nations are willing to agree on appropriate international standards.

what happens to your body when you die?
Answer: 24-72 hours after death — the internal organs decompose. 3-5 days after death — the body starts to bloat and blood-containing foam leaks from the mouth and nose. 8-10 days after death — the body turns from green to red as the blood decomposes and the organs in the abdomen accumulate gas.
Explanation: What happens to our bodies after we die isn’t a mystery, even if we may want it to be. If you want to confront the physical changes that take place, read on.
The first visible change to the body—occurring 15 to 20 minutes after death—is pallor mortis, in which the body begins to pale. Pallor mortis occurs because blood stops moving through the capillaries, the smallest of the body’s blood vessels. This process is identical for all people, but it’s less immediately apparent on people with darker skin.
Meanwhile, the body cools, decreasing in temperature about 1.5 °F (0.84 °C) per hour. But even when the body is cold, it’s still full of life. (Scientists liken a decaying body to an ecosystem.) Autolysis, which begins the process of decomposition, is also called “self-digestion”: enzymes begin to digest the membranes of oxygen-deprived cells. Damaged blood cells pour out of their broken vessels in a rush of movement. When they settle in the capillaries and other small blood vessels, they trigger discoloration on the skin’s surface. Though this discoloration (including a purplish blue hue and reddish spots) begins to set in about an hour after death, it usually isn’t visible until a few hours later.
Changes like those are almost infinite after death. When the body is alive, filaments consisting mainly of the proteins actin and myosin interact, binding with or releasing from one another to contract or relax muscles. That makes body movement possible. In death, chemical bridges gradually form between the actin and the myocin, so the muscles contract and stay that way till the bridges break down. This stiffness, known as rigor mortis, occurs about two to six hours after death. Rigor mortis adds to the difficulty of performing an autopsy or preparing a body for a funeral, as the body loses the flexibility it had during life. “It might take a little bit of force to break [the rigor mortis] up,” mortician Holly Williams explained in an interview with BBC Future. “Usually, the fresher a body is, the easier it is for me to work on.”
Among the living things in the human body are bacteria. While the body is alive, they are concentrated in the gut but are mostly kept out of other internal organs by the immune system. After death, though, these bacteria are free to “feed” on the whole body. First they digest the intestines and nearby tissue. Then they expand their reach, entering the capillaries and making their way into the heart and brain to feast. One study, by forensic scientist Gulnaz Javan and others, suggested that it takes bacteria 58 hours to spread to the liver, spleen, heart, and brain.
That stage of decomposition, called putrefaction, may be fully realized only after several days. The breakdown of carbohydrates, proteins, and other compounds in the body, caused largely by bacteria and by insect larvae, produces gases that swell the abdomen and eventually break the skin, which draws other insects to the feast. Decomposition takes time. How much time may depend on such factors as the cause of death, the environmental conditions, or even the clothing on the body. Decomposition is “a continuous process,” explained forensic scientist M. Lee Goff to Medical News Today, “beginning at the point of death and ending when the body has been reduced to a skeleton.”
To slow that arguably gruesome process, humans have devised various practices for preserving the body. A well-preserved body has long been a chief mortuary concern, especially when it will be displayed during a period of mourning. (After U.S. President Abraham Lincoln was assassinated, his body was taken on a train ride through seven states so citizens could view it, some waiting up to five hours for the honor.) Embalming is one way of preserving a body after death. A wide variety of substances—including vinegar, wine, brandy, and honey—have been used to “pickle” corpses and thus delay putrefaction. In the modern procedure of embalming, blood is drained from the veins, and another fluid, usually based on a solution of formaldehyde in water, is injected into a major artery. Cavity fluid is also removed and replaced with a preservative. Though this version of embalming isn’t permanent, it serves its purpose—giving the body a lifelike appearance in the days after death when it will be viewed by mourners.
Whether you choose to be embalmed in honey, embalmed the modern way, or not embalmed at all, you don’t have to worry too much about decomposition sneaking up on you. Chances are, your body isn’t going from flesh to bone anytime soon.

Why do teens need to eat more from the grains, fruits and vegetables food groups?
Answer:
Each group of foods (grains, fruits, and vegetables) enable teens to grow healthily, as these foods provide the sufficient nutrients and vitamins needed to do so. Grains provide fiber, b vitamins, and minerals, reducing the chances of becoming chronically ill. Vegetables and fruits are natural sources that provide essential vitamins for humans to live and grow (such as vitamin a and vitamin c). Vegetables and fruits are rich in these nutrients, as they help maintain a healthy blood pressure, their dietary fibers lowering the risks of heart disease, and also maintains (or boosts even) the health of our eyes, skin, and other essential parts of the body as well.

]Jane, a 22 year old, single Caucasian college freshman, had been in the emergency room for a reaction to alcohol. She had a blood alcohol level of .30 and was almost comatose. They were able to stabilize her in the ER. She had been binge drinking (over 4 drinks per night) for the last 2 weeks. She was admitted to the hospital for observation and stayed in the hospital for the next few days. When the alcohol was out of her system, she admitted to the counselor that she had been "hearing voices" belittling her for the last six months. She had been feeling people were talking about her on TV and on the radio and felt her professors and her roomate were conspiring against her. She stated she had felt this way for the past 7 months. She had become more and more socially isolated because of her mistrust of others and her grades had dropped. Jane said she started drinking to "drown out the voices" so she could sleep. She wanted the counselor to get the professors and her roomate to stop bothering her. According to Jane, her main problem was about the other people who were bothering her(professors and roomate) and she had just been drinking to help herself sleep and block out the "voices".
Jane had a great aunt who had been involuntarily hospitalized for an "emotional disorder". One of her siblings had Schizotypal traits and was considered a little unusual by others. She (Jane)had been an above average student in high school and in college until she began hearing voices and then she became a D student and was missing class frequently. Prior to this she had no mental health history but she had a history of being chronically suspicious and mistrustful of others that did not impair her overall functioning significantly. This had limited her friendships to a few that didn't last very long. She was intelligent and an A- average student in high school. Her physical health was affected by severe chronic asthma since age 3.
You should summarize the relevant historical information in the following format (Cut and paste into a word document):
Presenting problem: First list the demographic description of the person. Then indicate in 1 or 2 sentences how you think this person would describe their problem (in their "own words") if they were coming to you for treatment.
History of the presenting problem: Write 2-3 sentences here to describe the history of the presenting problem. Present information in chronological order.

Axis III: Medical conditions go here -
Axis IV: Psychosocial and environmental stressors, etc. - ****list and rate from 0- None, 1 - Mild, 2- Moderate, 3-Severe, 4 Very Severe, 5 - Catastrophic
Axis V: Global Assessment of Functioning (GAF Score) - 0-10 - needs constant supervision to 90-100 no symptoms, functioning can fluctuate so (state a range of 10 points)
****Convert the above diagnosis to DSM 5, 2013 format here: Collapse the first three diagnoses above in order in a sentence form. Delete the Axes labels. Then add a Note: to replace Axis IV just write a short description of the stressors; and Note: write a short description of the functional impairment
DSM-5 diagnosis -
Justification of diagnoses: Here you should explain why you picked each diagnosis you chose. Specifically, list the symptoms the person has that match up with symptoms required for diagnosis of the disorder in the DSM-IV and compare this to the justification for DSM 5, 2013 diagnosis. You may also wish to talk about other diagnoses you considered and tell why you eliminated them. If there is no diagnosis on one of the Axes for the DSM IV format, write No Diagnosis on the proper Axis. i.e., No diagnosis Axis ___
