Biomass Derived Syngas Cleaning Technologies | One of the fundamental steps to the successful operation of biomass gasification technologies for power generation is the efficiency of the gas cleaning step. Catalytic cracking is selected as the hot gas cleaning technology for this research using zeolite HZSM-5 catalyst in order to reduce tar produced from palm shell... | Abstract Incorporation of [U- 14 C]leucine in jack pine ( Pinus banksiana Lamb.) occurred mainly in the chloroplast and soluble cytoplasmic fractions. In the chloroplasts a major portion of the label was associated with the membrane-bound proteins. Fumigation of pine seedlings with gaseous SO 2 (0.34 ppm) for 24 and 48... | eng_Latn | 27,386 |
Development of ammonium bifluoride fusion method for rapid dissolution of trinitite samples and analysis by ICP-MS | Field deployable dissolution techniques are needed to decrease response time following a nuclear event. This study tested the capability of NH4HF2 fusion to dissolve trinitite. Dissolution of trinitite by NH4HF2 fusion was compared to conventional microwave digestion. Following digestion, trace elements were measured u... | The invention discloses a fluoro-substituted triptolide derivative shown as formula (I) or its pharmaceutically acceptable salt or hydrate or their optical isomer, wherein the -- connecting OH and F can represent the following meaning. The invention also discloses a preparation method of the fluoro-substituted triptoli... | eng_Latn | 27,401 |
Feasibility study of lactate imaging of head and neck tumors. | A proton spectroscopic imaging sequence was used to investigate the feasibility of lactate imaging in head and neck tumors. The sequence employs a two-shot lactate editing method with inversion recovery for additional lipid suppression, and a restricted field of view to suppress motion artifacts. Variations in acquisit... | Abstract The neutralization process of the depolarization field in L-α-alanine doped triglycine sulfate (LATGS) was investigated by the observation of the polarization charge on the surface of LATGS from the moment of cleavage. The charges which were equivalent to such a high voltage as 5kV were actually induced on the... | eng_Latn | 27,427 |
Anomerization of glucose 6-phosphate: pH dependence and solvent isotope effects☆ | Abstract The anomerization of α- d -glucose 6-phosphate has been examined using a spectrophotometric coupled enzyme assay. The pH-rate profile for spontaneous d -glucose 6-phosphate anomerization reveals that the d -glucose 6-phosphate dianion is the species giving rise to the much higher rate of d -glucose 6-phosphate... | Background and Objective Chemotherapeutic drug treatment outcomes are genetically determined. Polymorphisms in genes encoding phase II drug metabolizing enzyme glutathione-S-transferase (GST) can possibly predict treatment outcomes, and can be of prognostic significance in breast cancer patients. The aim of this study ... | eng_Latn | 27,438 |
