Energy

I, personally, have very little background in physics compared to most other scientists. I am fairly young, so I suppose that is to be expected. I still can't help but be perplexed with what seems to me as over-complicating the system. These are just my thoughts on the matter. Feel free to correct any errors. I'll blame my ineptitude in the field and my youth. Are DNA mutations random or purposeful? Evolution is change. Changes that occur during DNA replication and because of radiation exposure all have chemical causes, and I think that at the very least some portion of them are random, if…

Food and Biofuel Production: New Challenges Ahead Energy is a crucial and vital ingredient for the modern development of economic activities of our society. It provides services for cooking, space and water heating, lighting, health, food production and storage, education, mineral extraction, industrial production and transportation. It is so crucial that, throughout the world, the energy consumption patterns largely determines the way in which people live their lives. A review of current and future overall energy scenarios shows three main critical issues. First, only 25 percent of the world…

It is estimated that biomass covers currently up to 15% of the world energy demand, almost 1/3 of all energy consumption in the Less-Developed Countries. This rate was over the last years rather constant, with increasing overall demand bioenergy consumption increased in absolute terms.

Saline water occupies 71% of the Earth area. It is thought that even a quarter of the whole pedosphere is affected by salts (Glenn and O’Leary, 1985), amounting to 950 x 106 ha (Flowers and Yeo, 1995), while 23 % of the 1.5 x 109 ha cultivated land is considered as saline (Rhoades and Loveday, 1990). Furthermore, about a half of all the existing irrigation systems of the world (3 x 108 ha) are under the influence of secondary salinization, alkalization and waterlogging, and about 10 x 106 ha of irrigated land are abandoned each year because of the unfavorable effects of secondary salinization…
