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

IC02 Causes and Spread of Infection 1. Understand the causes of infection 2.1 Identify the differences between bacteria‚ viruses‚ fungi and parasites. Bacteria – bacteria are extremely small singular organisms which are found almost everywhere. Viruses – it is a coated genetic material that invades cells and use’s the cells apparatus for reproduction. Fungi – it is a multi-celled living organism Parasites – they are types of living plants and animals that derive benefit

Geotechnical Engineering Practice | August 19‚ 2012 1 The origins of soil deposits on the earth’s crust can reveal significant findings in the chemical and mechanical characteristics of the soils themselves. It is important to uncover such origins to find how and where such deposits may have formed over tens of thousands of years ago. Marine and Lacustrine deposits are two soil types that are commonly encountered during soil exploration‚ both of which are primarily traced back to either glacial

1. Black soils The principal region of black soils is the Deccan plateau and its periphery extending from 8°45’to 26o north latitude and 68o to 83o45’ east longitude. They are formed from Deccan basalt trap rocks and occur in areas under the monsoon climate‚ mostly of semi-arid and sub-humid types. The overall climate of black soil region may be described as hot and dry summer‚ 40-100 cm rainfall per annum‚ mild to moderate winters and annual temperature ranges from 24-30o centigrade‚ mean maximum

Skin infections are common‚ but the bacteria can spread through the bloodstream and infect distant organs. Skin infections may cause blisters‚ abscesses‚ and redness and swelling in the infected area. The diagnosis is based on the appearance of the skin or identification of the bacteria in a

his experiment was done to find out if garlic is effective in killing bacteria. This will help us understand the effectiveness of home remedies such as the use of natural herbs (including garlic) for medicinal purposes. Hypothesis Garlic will kill bacteria and prevent its further growth. Background Herbs and spices have traditionally been used in cooking as they add flavor to our food. These herbs and spices have also been known to many cultures for their medicinal properties. The oils that are

Watershed Management and Soil Erosion Forests provide a buffer to filter water and to hold soil in place. They sustain water and soil resources through recycling nutrients. In watersheds where forests are degraded or destroyed‚ minimum flows decrease during the dry season‚ leading to drought‚ while peak floods and soil erosion increase during the wet season. Flooding along the Baram River in Sarawak has increased significantly since logging began‚ the major floods occurring in 1979 and 1981.168

Exploring the diversity‚ abundance‚ and variability of diatom-associated bacteria in the oligotrophic ocean I. Abstract The ecology of diatoms may be better explained by conceptualizing them as composite organisms consisting of the host cell and its bacterial associates. Our previous investigated diatom-bacterial interactions at the single-cell level found that bacterial assemblages varied substantially even among closely related individual host cells. The bacterial assemblages associated with single

research scientist with a profitable side practice treating the syphilis infections of prominent London artists‚ was pursuing his pet theory--that his own nasal mucus had antibacterial effects--when he left a culture plate smeared with Staphylococcus bacteria on his lab bench while he went on a two-week holiday. When he returned‚ he noticed a clear halo surrounding the yellow-green growth of a mold that had accidentally contaminated the plate. Unknown to him‚ a spore of a rare variant called Penicillium
