As of 2011‚ 99% of Mercury’s surface has been mapped by NASA. Overall‚ Mercury’s surface has many similarities to the Moon’s surface with many plains and craters. The largest crater on Mercury is the Caloris Basin with a diameter of 1550km. Venus‚ the second planet from the Sun‚ is a solid and rocky terrestrial planet. Named by the

proved to be the safest and most effective method of increasing and sustaining yield. Various methods fall under organic farming‚ such as composting‚ green manuring‚ legume inoculating‚ and utilizing animal manure as fertilizers. Mulching is a simple process that increases soil fertility and regulating several factors affecting overall plant growth. In this method‚ a layer of material-the mulch-is placed on soil surface around the plant. The mulch is used to retard the growth of weeds‚ protect roots

Title______________________________________________________________________ Influence of Rhizobium on the growth and yield of Rice Abstract___________________________________________________________________ Rice (Oryza sativa L.) is one of the world’s most important crops. The present investigation was designed to assess the range of growth-promoting activities of various diazotrophic bacteria on rice seedling vigor‚ its carryover effect on straw and grain yield‚ and the persistence of an inoculant strain on rice roots under greenhouse

A shaping process changes the geometry of the work material (machining or forging). A surface processing operation does not alter the geometry‚ but instead alters the properties and/or appearance of the surface of the

Soil is one of the most important natural resources of man. Soils are essential for man for growing crops‚ fodder and limber. Once the fertile portion of the earth’s surface is lost‚ it is very difficult to replace it. In India‚ the destruction of the top-soil has already reached an alarming proportion. Land degradation problems have resulted in increasing depletion of the productivity of the basic land stock through nutrient deficiencies. In addition to the direct loss of crop producing capacity

The factors that would cause the lung to collapse are elastic recoil and high surface tension. And the factors that prevent the lungs from collapse are negative intrapulmonary pressure and surfactant. During expiration : volume increase and pressure decrease During inspiration : volume decrease and pressure increase The role of surfactant is to decrease surface tension by more than 40 times. And it’s effect on surface tension is to prevent them from PO2 in alveolar : 104 PO2 in venous blood
