World population is about 6.3 billion and growingat about 2%per annum,givinga doubling period of 35 years. Global energyproduction for 2005isprojected to be about 12600 million tonnesoil equivalent (TOE),an average of 2t perperson, very unevenly distributed.

  • Biomass Properties and Prediction Tools for Vegetation Wildland-Urban Interface (WUI) Fires 1.1 Overview Wildland fires are natural calamities that bring enormous environmental and economic damage worldwide and some of them cause human death. Achieving effective fire fighting is associated with the possibilities of predicting the characteristics of fire behaviour. Special attention needs to be drawn to meteorological conditions and their effect on fire spread in a bed of vegetation.

  • From all of these perspectives, the evidence gathered by the Review leads to a simple conclusion: the benefits of strong, early action considerably outweigh the costs. The evidence shows that ignoring climate change will eventually damage economic growth. Our actions over the coming few decades could create risks of major disruption to economic and social activity, later in this century and in the next, on a scale similar to those associated with the great wars and the economic depression of the first half of the 20th century. And it will be difficult or...

  • Ozone presents difficulties. It is an important issue which may grow in importance in the future if, as anticipated, concentrations rise, but the only acceptable way of monitoring it at remote locations, without a power supply, is diffusion tubes. These have been used in the ICP Forests Level 2 programme, but do not give values for peak ozone incidents, which are believed to cause visible ozone symptoms.

  • In the study performed by Purushotham et al. (2011) showed that about 28% of total hardness in the study site exceeded the desirable limits at 600 mg L-1. Naturally, the water hardness is due to the presence of alkaline earths such as calcium (Ca) and magnesium (Mg). Excess of magnesium affects the soil quality, which results in poor crops yield. The high concentration of magnesium and calcium can cause decrease in water quality and may cause encrustation in the water supply structure.

  • Wildland fires are natural calamities that bring enormous environmental and economic damage worldwide and some of them cause human death. Achieving effective fire fighting is associated with the possibilities of predicting the characteristics of fire behaviour. Special attention needs to be drawn to meteorological conditions and their effect on fire spread in a bed of vegetation. On the other hand, studying the effect of forest fires on the environment is of equal significance for building the strategy and specific actions to be undertaken in the fire fighting process.

  • Barrier methods are not yet out of fashion! In spite of well-known disadvantages, they all (notably condoms) provide useful protection against STIs. All users of this type of method should be informed about EC, in case of lack of use or failure in use. Vegetable- and oil-based lubricants, and the bases for many prescribable vaginal products, can seriously damage and lead to rupture of rubber: baby oil destroys up to 95% of a condom’s strength within 15 minutes.

  • Harrison's Internal Medicine Chapter 118. Infective Endocarditis Infective Endocarditis: Introduction The prototypic lesion of infective endocarditis, the vegetation (Fig. 118-1), is a mass of platelets, fibrin, microcolonies of microorganisms, and scant inflammatory cells. Infection most commonly involves heart valves (either native or prosthetic) but may also occur on the low-pressure side of the ventricular septum at the site of a defect, on the mural endocardium where it is damaged by aberrant jets of blood or foreign bodies, or on intracardiac devices themselves.

  • Corn gluten meal is a natural pre-emergent fertilizer (9.5-0.5-0.5) that reduces the germination and establishment of troublesome annual weeds. It is available as a powder or in granular form. It is 60 percent protein and approximately 10 percent nitrogen by weight. It is a by-product of the wet milling process and commonly used in pet and livestock feed. It can be used in vegetable gardens as a fertilizer and can help with weed control, but be careful. It can damage the germination of your food crops. Use it only after your vegetable seeds are up and young plant roots are...

  • Antioxidants are man-made or natural substances that may prevent or delay some types of cell damage. Diets high in vegetables and fruits, which are good sources of antioxidants, have been found to be healthy; however, research has not shown antioxidant supplements to be beneficial in preventing diseases. Examples of antioxidants include vitamins C and E, selenium, and carotenoids, such as beta-carotene, lycopene, lutein, and zeaxanthin.
