In situ emulsion formation is an effective nonthermal method to improve conventional heavy-oil recovery. this paper, a newly designed viscosity reducer (TPVR7) and high-performance surfactant (dioctyl sodium sulfosuccinate, DSS) for enhanced recovery have been introduced evaluated. A dewatering rate test, droplet size measurement, multiple-light scattering, interfacial tension measurement are carried out evaluate the synergistic effect of on stability efficiency in enhancing The results show...
Proteins hydrolyzed by enzymes were biologically active. The protein‐rich, defatted Tenebrio molitor was used as raw material and alkaline protease. effects of temperature, time, pH, liquid‐to‐feed ratio, enzyme addition investigated with degree hydrolysis (DH) an index; the enzymatic process optimized using one‐way response surface experimental methods, antioxidant, physicochemical properties, amino acid compositions hydrolysates analyzed. results showed that optimum conditions for...
The emulsification of heavy oil and water into a W/O emulsion would increase the viscosity reduce mobility oil. As we know, addition reducer such as water-soluble surfactants could change status improve Although up to 90% reduction be achieved in laboratory experiments, field improvement recovery is not satisfactory with reducer. Actually, it related difference mixing process reducer, water, between lab experiments subsurface flow formation. significantly affected by temperature...
Industry in general has seen many technological developments recent decades. However, the construction industry not kept pace particularly within area of information and communication technologies (ICTs). This could be for reasons notably including fragmented structure industry. Many studies regard industry’s failure to keep with ICTs as a major problem affecting its performance. Hence, they have tried diagnose this regard. drivers successful adoption new other industries trend now emerging...
Abstract: In China, the pattern of farmland use has been greatly changed due to rapid development economy, since economic reform in 1978. Variations available farmland, terms both quantity and quality, have brought about changes grain production. This paper analyzes spatiotemporal China' s level for period 1978 2004, develops a “farmland—grain elasticity coefficient” (FGEC) reflect interrelationship between levels production, using agricultural statistical data from local governments. The...
The receptor tyrosine kinase AXL is a promising target for anticancer drug discovery. Herein, we describe the discovery of 3-aminopyrazole derivatives as new potent and selective inhibitors. One representative compounds, 6li, potently inhibited enzymatic activity with an IC50 value 1.6 nM, tightly bound protein Kd 0.26 while was obviously less against most 403 wild-type kinases evaluated. Cell-based assays demonstrated that compound 6li signaling, suppressed Ba/F3-TEL-AXL cell proliferation,...
Chemical investigation of the anti-inflammatory Chinese folk medicine Calophyllum membranaceum has resulted in isolation and characterization three new xanthones (1−3), one biphenyl C-glycoside (4), phenylethanoid glycoside (5) along with 17 known compounds. Their structures were characterized on basis spectroscopic chemical methods. Two xanthones, 2,6-dihydroxy-1,7-dimethoxyxanthone (1) 3,4-dihydroxyxanthone, found to exhibit selective inhibitory activity against cyclooxygenase-2 (IC50 =...
Four new flavan-4-ol glycosides, abacopterins A-D (1-4), were isolated from a methanol extract of the rhizomes Abacopteris penangiana, together with two known compounds, triphyllin A (5) and 6,8-dimethyl-7-hydroxy-4'-methoxyanthocyanidin-5-O-beta-D-glucopyranoside (6). Their structures elucidated by extensive spectroscopic analysis chemical methods. The cytotoxic activity 1-5 against HepG2 human hepatoma cells was investigated.
Abstract Although there is abundant heavy oil resource in Bohai oilfield, only limited production obtained by cold technologies past. The practical challenges of thermal such as steam injection for offshore produciton include the difficulty to install large conventional generator onto platform, and heat loss during long wellbore. In order recover Oilfield effectively platform lifetime, a compact modular gas was firstly introduced generate steam, CO2 N2 using diesel or natural fuel, which...
Sporormielones A–E, novel C–C coupled orsellinic acid derivative dimers containing tricyclic cores with a dimethylcyclopentenone unit, were isolated from <italic>Sporormiella</italic> sp., and their plausible biosynthetic mechanism was proposed.
