BACKGROUND Using positron emission tomography (PET), we compared two tracers, [11C]metomidate ([11C]MTO) and [11C]acetate ([11C]ACE), for the characterization of hepatic tumors. METHODS Thirty-three patients underwent PET with [11C]MTO and [11C]ACE and magnetic resonance imaging (MRI). Based on the histology of the tumor biopsy, 14 patients had hepatocellular carcinoma (HCC), 9 patients had f...
Duckweed biomass is gasified in a thermochemical-based superstructure to produce gasoline, diesel, and kerosene using a synthesis gas intermediate. The superstructure includes multiple pathways for conversion of the synthesis gas to liquid hydrocarbons via Fischer−Tropsch synthesis or intermediate methanol synthesis. Low-temperature and high-temperature Fischer−Tropsch processes are examined us...
Recently, manufacturers are taking a hybrid approach between MTS and MTO. However, most of literature research on production planning concentrates principally on MTS systems. The MTO area has not received the same degree of attention. There are only some research papers which are based on queueing network models that explicitly talk about the Lot Sizing Problem (LSP) in MTO sector. This paper p...
Mineraloils have long been utilizedin industriesas machining lubricants, which contributed to theirdepletion and hick in priceandbeing non-biodegradable, harmful the environment,and risk health.Plant-basedoil is more biodegradable, renewable, environmentally friendlyas a green alternative.However, their crudestate, plant-based oilsare not up par with standard mineral oil used lubricationin term...
The presented report focuses on an in-depth detailed characterization of immobilized methyltrioxorhenium (MTO), giving catalysts with a wide spectra of utilization. The range of mesoporous materials with different SiO₂/Al₂O₃ ratios, namely mesoporous alumina (MA), aluminosilicates type Siral (with Al content 60%-90%) and MCM-41, were used as supports for immobilization of MTO. The tested suppor...
This paper addresses one of the most important issues have been considered in hybrid MTS/MTO production environments. To cope with the problem, a mathematical programming model is applied from a tactical point of view. The model is converted to a fuzzy goal programming model, because a degree of uncertainty is involved in hybrid MTS/MTO context. Finally, application of the proposed model in an ...
Protein subunit vaccines present a compelling new area of research for control of tuberculosis (TB). Based on the interaction between Mycobacterium tuberculosis and its host, five stage-specific antigens of M. tuberculosis that participate in TB pathogenesis--Rv1813, Rv2660c, Ag85B, Rv2623, and HspX--were selected. These antigens were verified to be recognized by T cells from a total of 42 whol...
