Pyrolysis of agricultural waste to produce fuel gas involves formation of tars as noxious by-products. In this paper the qualitative analysis of tars formed during pyrolysis of rice husks is presented, based on identification by gas chromatography-mass spectrometry and interpolation of retention times on a polyaromatic hydrocarbon index scale. The influence of some reaction parameters on produc...

industrial waste management is one of the most properly approaches which make industry and environment collaborating and coacting as well as reduce impacts of industry on environment. in this study, present management of yazd industrial township located in yazd province was studied. in order to properly manage and control waste production, questionnaires were used to collect data regarding type...

Thermoacoustic heat engines (TAEs) are potentially advantageous drivers for thermoacoustic refrigerators (TARs). Connecting TAEs to TARs means that waste heat can effectively be utilized to provide cooling, and increase overall efficiency. However, this is currently a niche technology. Improvements can be made through a better understanding of the interactions of relevant design parameters. Thi...

Introduction: Mars is host to a wide range of aeolian forms such as dunes, ripples, dust devils, dust storms, yardangs, and ventifacts. Large dune fields characterized by low albedos and large duneform sizes have been observed and occur mainly around the north polar cap and in the southern mid-latitudes. However, another morphologically and dimensionally distinct population of aeolian bedforms ...

Aminoacyl-tRNA synthetases classically regulate protein synthesis but some also engage in alternative signaling functions related to immune responses and angiogenesis. Threonyl-tRNA synthetase (TARS) is an autoantigen in the autoimmune disorder myositis, and borrelidin, a potent inhibitor of TARS, inhibits angiogenesis. We explored a mechanistic link between these findings by testing whether TA...

Despite the high mortality rate of ovarian cancer, there are few selective biomarkers that detect its progression and none have become successful targets for therapy. A complex microenvironment that promotes angiogenesis, reduces immune responses and alters the integrity of the surrounding matrix is involved through the biology of ovarian cancer. Previous studies done by our lab and collaborato...

[1] Narrow-angle images from the Mars Orbiter Camera (MOC) have revealed the common occurrence of small-scale (<100 m wavelength) bright transverse aeolian ridges (TARs) on the surface of Mars. MOC images were used to assess the broad distribution of TARs from 90 N to 90 S between 180 E and 240 E to investigate their relationship to latitude, elevation, thermal inertia, geologic units, local sl...

Cocultivation of spleen cells, lymph node cells, and thymocytes of female Wistar-King-Aptekman rats with short-term cultured male adult T cell leukemia (ATL) cells in the presence of 5-bromo-2'-deoxyuridine (BrdUrd) resulted in the establishment of rat lymphoid cell lines, TARS-1, TARL-2, and TART-1. Cytogenetic analysis of the three cell lines showed a female rat karyotype with 42 chromosomes....
