Supercritical water oxidation has attracted attention of many researchers ever since the ideahas emerged about three decades ago as a promising technique in the waste managementindustry. Providing more details about the behavior of a supercritical water oxidation systemunder various operating conditions and extending available data can greatly assist more accurateand reliable design of such sys...

Sitting in our offices early in the morning of September 11, 2001, we, like many across the world, watched with incredulity the twin terrorist strikes on the World Trade Centre. Riveted to the television screen, we witnessed the beginnings of a nightmare whose images will likely remain with us for a long time. September 11, and the events that followed, changed our assumptions of world terroris...

Since the late 1970s, Libyan leader Colonel Muammar Qadhafi has sought to obtain weapons of mass destruction (WMD), particularly chemical and biological weapons (CBW). By the late 1980s, Libya had developed a rudimentary capability to produce such weapons. Western experts view the pursuit of CBW as a means of bolstering Libya’s military capability, since the country lacks effective conventional...

Uncertainty about behavior: Uncertainty about behavior refers to uncertainty regarding the actions taken by others. Sometimes it is hard to know what other states are doing – in particular, if they are cooperating or defecting. Consider weapons of mass destruction. Whatever a state may say publicly, it is very difficult for others to ascertain whether it is pursuing technologies associated with...

The far ultraviolet rays are harmful to human health, particularly for their mutagenic effects; it can cause skin cancer, cataracts, photochemical pollution. In the future, chemists plan use as weapons destruction of objects. Therefore, we should meet this future challenge by scientific means in order snuff out its far-ultraviolet rays. paper, we’ve intend carry a deep spectral study on series ...

A locally isolated Acinetobacter sp. Strain AQ5NOL 1 was encapsulated in gellan gum and its ability to degrade phenol was compared with the free cells. Optimal phenol degradation was achieved at gellan gum concentration of 0.75% (w/v), bead size of 3 mm diameter (estimated surface area of 28.26 mm(2)) and bead number of 300 per 100 ml medium. At phenol concentration of 100 mg l(-1), both free a...

The soil yeast Trichosporon cutaneum, which is distinguished by having a strictly oxidative metabolism, can be induced to utilize phenol as a sole carbon source. The present paper shows that such phenol-induced cells contain a specific, energy-dependent uptake system for phenol. Phenol uptake is not directly linked to its o-hydroxylation inside the cell, the first step of phenol metabolism. The...
