Hormone Use In Livestock
449 Words - 2 Pages.... on PST will consume less food and reach market age faster. Good management enhances the effect of PST. Research has made an indication that pigs that have been treated with PST are leaner. Their meet is very similar in color, taste, tenderness, and juiciness to those who have not received PST.
As pigs grow closer to market weight, they produce less PST, which results in poor feed efficiency. The muscle gain stays fairly constant while more nutrients taken in by the animal are used in fat production causing the animal to require more energy for the production of muscle. Manufactured PST will provide a boost in the natural levels of PST in a maturing pig. If there is ....

Effects Of Asperguillus
292 Words - 2 Pages.... settle in some part of the ventilation system. Spores are also stirred
up from construction and renovation. Additional sources of the fungal spores
could be contaminated or wet wood, bird droppings in air ducts, or decaying
fireproofing materials. The fungus causes pneumonia in a host with a weak or
otherwise compromised immune system. Patients at risk are those undergoing
organ transplant or bone marrow transplants, and depending on the type of
transplant, mortality rates are as high as 95%. Bone marrow transplant patients,
the highest risk group, should be treated like they are immunosuppressed for up
to four weeks after the procedure. The portal of entry is ....

Mechanical Energy
506 Words - 2 Pages.... as energy to lift the aircraft off the surface of earth.
Fuel can take the form of gases, solids or liquids. When fuels combine with oxygen from the air, they release their stored energy as heat. We recognize this process as burning. The individual relies on food for fuel which contains energy-giving substances that our bodies can store until we need this energy to use our muscles. When we do use our muscles within us, we may not always be sure that heat is given off. Our bodies do not burst into flames but the perspiration on our skin is a clue to what is happening.
The movement of the windsurfer has a different explanation. The windsurfer is propelled along by a ....

Carnivorous Plants
1430 Words - 6 Pages.... found growing almost side by side. They are
most likely to be found in swamps, bogs, damp heaths and muddy or sandy shores.
Drosophyllum lusitanicum from Portugal and Morocco is the one exception, it
grows on dry gravelly hills. Like other green plants, carnivorous plants
contain the organic pigment chlorophyll. This pigment helps to mediate a
chemical process called photosynthesis. This converts light energy into the
chemical bond energy of carbohydrate which is utilized as cellular energy, plant
growth and development. Water, carbon dioxide, nutrients and minerals are also
needed for survival. In wetlands, where stagnate water contains acidic
compounds and chemicals fr ....

Newton's Laws Of Motion
484 Words - 2 Pages.... movement. One surface tends to work against, or resist, any motion of the other surface. For example, there is a friction between a wood floor surface and the surface of a rubber ball when it is rolled across the floor. The floor surface resists the motion of the rubber ball surface. This resistance or friction will slow down the moving object and eventually bring it to a stop. Friction exists between any two surfaces that touch, slide, or roll on one another.
Any change in an object’s speed is called acceleration. An increase in speed is called positive acceleration, while a decrease in speed is called negative acceleration, or deceleration. Acceleration can ....

Minerals
417 Words - 2 Pages.... to repay the investment and make profit. Of the many mineral found, there is only a few mineral will appear to have good potential. So it must be tested widely, which costs a lot of time and speed is one of the critical factors. If the construction is financed by loans, it leads up to high interest costs.
The economics of a mine depends upon ore reserves, grade, type of ore, and the location. In order to mine, many months and millions of dollars have to spend in construction. There are only a few mines are discovered in convenient places, this costs a lot on transportation and labor on such an atmosphere. Construction includes food, health, accommodation and recreatio ....

Ebola Virus 4
2184 Words - 8 Pages.... highly variable in length apparently owing to concatemerization. However, the average length of an infectious virion appears to be 920 nm. The virions are 80 nm in diameter with a helical nucleocapsid, a membrane made of 10 nm projections, and host cell membrane. They contain a unique single-stranded molecule of noninfectious (negative sense ) RNA. The virus is composed of 7 polypeptides, a nucleoprotein, a glycoprotein, a polymerase and 4 other undesignated proteins. Proteins are produced from polyadenylated monocistronic mRNA species transcribed from virus RNA. The replication in and destruction of the host cell is rapid and produces a large number of viruses budding from ....

341 Words - 2 Pages.... person is sad, irritable, has low self-esteem, negative thoughts, and loss of interest in usual activities. They feel like they’re worthless and hopeless. They also have negative thoughts towards the past and future. Many people go
through guilt, crying, or having suicidal thoughts. Unlike a manic episode, the person has lack of energy, and either an appetite loss or gain.
Manic depression is a recurrent illness, so a person usually has more than one episode. These episodes can last from weeks to months. They occur whenever and have no certain pattern. Sometimes a stressful life event can trigger an episode, and sometimes they just happen. If a person has more th ....
