This study focuses on 540 households originally living in public housing in high-poverty areas of Boston who participated in HUD’s Moving To Opportunity (MTO) demonstration. Participants were randomly assigned to one of three groups: Experimental – offered mobility counseling and a Section 8 subsidy valid in a 1990 Census tract with a poverty rate of less than 10 percent; Section 8 Comparison –...
Major problems of cancer treatment using systemic chemotherapy are severe side effects. Magnetic drug targeting (MDT) employing superparamagnetic iron oxide nanoparticles (SPION) loaded with chemotherapeutic agents may overcome this dilemma by increasing drug accumulation in the tumor and reducing toxic side effects in the healthy tissue. For translation of nanomedicine from bench to bedside, n...
The mechanisms of the inotropic effect of mitoxantrone (MTO), a synthetic dihydroxyanthracenedione derivative with antineoplastic activity, was investigated in guinea pig ventricular myocytes using whole-cell patch-clamp methods combined with fura-2 fluorescence and cell-edge tracking techniques. In right ventricular papillary muscles, 30 microM MTO increased isometric force of contraction as w...
The nature and evolution of the hydrocarbon pool (HP) species during the Methanol-to-Olefins (MTO) process for three small-pore zeolite catalysts, with a different framework consisting of large cages interconnected by small eight-ring windows (CHA, DDR, and LEV) was studied at reaction temperatures between 350 and 450 °C using a combination of operando UV-vis spectroscopy and online gas chromat...
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...
Abstract. SAPO-34 and ZnAPO-34 materials (Zn incorporated by isomorphic substitution in AlPO-34 material) were synthesized hydrothermal synthesis using triethylamine (TEA) as the structure directing agent (SDA). The presented both is to chabazite zeolite (CHA). However, they have different properties such textural (Z34 S34 a surface area of 485 603 m2/g, respectively), crystal sizes acid prop...
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...
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...
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 ...
