Introduction Every type of soil has its own percentage of moisture content. The void in soil content water and air. The moisture content may varies for each types of soil. Different type of soil has different moisture content. Moisture content of soil also may be affected by the climate where the high humidity country tend to have higher moisture content in soil. Size or structure of the soil particles also affecting the moisture content. The properties of the soil to retain water also one of the

SOIL NAILING FOR STABILIZATION OF SLOPES Abstract: After its development in early 1980’s it become widely used in method of providing permanent and temporary support for earth‚ and stabilization of slope on many engineering projects in world wide. In starting of this period soil nailing was only performed on that project where geotechnical contractor provide this as an alternative to other soil improvements techniques. Now a days soil nailing is accepted only because of its performance and effectiveness

Water and mineral ions must be supplied and conserved in the plant. cell wall makes plants have no mobility cell wall bring turgor pressure. Turgor pressure increased in ‘woody plants’ - with lignin. photosynthesis - is the process whereby radiant energy from the sun is

Sporadic Alzheimer’s disease: The Disease of the Century Estimated about fifteen million people worldwide have been diagnosed with Alzheimer’s disease. Some scientists believe that almost ninety percent of all Alzheimer’s disease is sporadic. Sporadic Alzheimer’s is a type of Alzheimer’s that either men or women of all ages can be affected‚ although most cases occur in people over 65 years of age. Alzheimer’s disease (AD) is a fatal disease of the brain that affects brain functions such as memory

Communicable Disease/Hepatitis Francois Drof HCS/457 March 18‚ 2013 Lindsay Cogan Communicable Disease/Hepatitis B The communicable disease I have chosen for this paper is Hepatitis. Hepatitis B is a liver disease that is caused by the hepatitis B virus (HBV). This virus can cause infections that can last a life time. These infections include cirrhosis of the liver (scarring)‚ liver cancer‚ liver failure‚ and ultimately death. Hepatitis B is highly contagious and this disease affects one

A population grows exponentially when it has all of the resources it needs and disease and predation do not occur. 3b. Exponential growth shows a “J shaped” curve because with each generation‚ the number of organisms producing offspring increases‚ resulting in a rapid increase in population size. 4a. A logistic growth curve has an

Bacterial diseases: Introduction Bacterial diseases include any type of illness or disease caused by bacteria‚ a type of microbe. Microbes are tiny organisms that cannot be seen without a microscope and include viruses‚ fungi‚ and some parasites as well as bacteria. The vast majority of bacteria do not cause disease‚ and many bacteria are actually helpful and even necessary to good health. Millions of bacteria normally live on the skin and in the intestines and can also be found on the genitalia

thing made from another‚ leading to two organisms with the same set of genes. In that sense‚ identical twins are clones‚ because they have identical DNA. Sometimes‚ plants are self-pollinated‚ producing seeds and eventually more plants with the same genetic code. Some forests are made entirely of trees originating from one single plant; the original tree spread its roots‚ which later sprouted new trees. When earthworms are cut in half‚ they regenerate the missing parts of their bodies‚ leading to

A. Trachoma This is an infectious disease caused by the bacterium “Chlamydia trachomatis”. The infection causes the inner surface of the eyelids to become rough leading to pain in the eye‚ breakdown of the cornea and possible blindness. Untreated‚ repeated trachoma infections result in entropion - a painful form of permanent blindness when the eyelids turn inward‚ causing the eyelashes to scratch the cornea. Children are the most susceptible to infection due to their tendency to easily get dirty
