The hydroisomerization of pure n-pentane over H-mordenite supported Pt-catalyst was investigated in a fixed bed reactor by changing reaction parameters such as temperature, pressure, and WHSV, as well as the H2/HC ratio. The maximum yield of isopentane over Pt/mordenite catalyst was achieved at 220 °C and a relatively low reaction pressure. To address the effect of feed composition on the catal...

Canola has the lowest content of saturated fat amongst oils marketed in North America, and therefore is a valuable nutritional component for food industry and household use. Oils, extracted from vegetable tissues, contain a number of impurities which have to be removed in order to make the oil suitable for human consumption. One such impurity consists of waxes, which are high melting esters of ...

Raman spectroscopy coupled with K-means clustering analysis (KMCA) is employed to elucidate the biochemical structure of human skin tissue sections and the effects of tissue processing. Both hand and thigh sections of human cadavers were analyzed in their unprocessed and formalin-fixed, paraffin-processed (FFPP), and subsequently dewaxed forms. In unprocessed sections, KMCA reveals clear differ...

Modern use of petroleum-derived oils as agricultural crop protectants dates back to the 1800s, but it was not until the latter half of the 20th century that advances in petroleum chemistry allowed substantial modification and diversification in their commercial applicability. In the 1880s, a kerosene–soap emulsion was used with some success against scales and aphids in citrus trees. The search ...

congenital toxoplasmosis is associated with variable complications including encephalitis, microcephaly, hydrocephaly, hepatitis, lymphadenopathy and even intrauterine death. presence of toxoplasma gondii in human placenta may induce congenital infection. the aim of this study was to determine the genotypes of toxoplasma gondii infection in human spontaneous aborted fetuses in shiraz, south of ...

Biodiesel (BD) is receiving increased attention as an alternative, non-toxic, biodegradable, and renewable diesel fuel. Exploring new energy resources, such as BD fuel, is of growing importance in recent years. The main concern with BD fuel is its high price. One of the future aims in BD research is on the selection of inexpensive feedstock with high value–added byproducts. Rice bran is a by-pr...
