ABSTRACT This paper investigates the ignitability and effectiveness of burning crude oil spills at sea with respect to type oil, weathering time, seawater emulsion content. In event an or fuel spill sea, in situ can be a practical method removing preventing it from reaching vulnerable coastlines. However, specific chemistry its resulting behavior dictates how well this works. order understand b...

The hot cracking susceptibility can be determined by establishing the transition temperature between brittle and ductile fracture at high temperature tensile testing of in situ solidified samples. High temperature tensile properties were determined for commercial cathodic pure Cu and Cu- 30%Zn alloy. The transition temperatures for pure Cu and Cu-30%Zn were evaluated from ultimate tensile stres...

soil affected by salt (nacl) is a major problem worldwide and in areas with potential agriculture; lands in many countries are not enough to support crop production. the development of salt tolerant cultivars would be enhanced by better understanding of the genetic control of tolerance to salt stress. a new cereal, tritipyrum, a range of amphiploids between triticum spp. and thinopyrum spp....

natural radionuclides present in soil as well as certain anthropogenic radionuclides released to the environment are the major contributors to terrestrial outdoor exposures. in the assessment of human exposures from environmental radioactivity, besides the conventional method of soil and vegetation sampling combined with laboratory based analyses of environmental media, the other choice would b...

the simultaneous flow of oil and water in porous media is described by relative permeability curves, mainly derived from laboratory experiments. relative permeability is of paramount importance in predicting reservoir production performance and drive mechanisms and its value depends largely on the volume fraction of fluids present in the test samples. nowadays x-ray scanners are one of the most...

juvenile fibroadenoma is an uncommon histologic variant of fibroadenoma that frequently shows a remarkable and rapid growth. the development of a carcinoma within a fibroadenoma, either in situ or invasive, is a rare condition. we encountered a 36-year-old woman with a palpable mass in the right breast. the radiologic findings were indicative of a fibroadenoma in the breast. sonographic guided ...
