In this paper, the coating of TiO2 nanoparticles onto surface a polyamide thin film composite nanofiltration membrane has been studied. Changes in properties and separation performance modified membranes were systematically characterized. The experimental results indicated that hydrophilicity was significantly improved by presence coated with subsequent UV irradiation. UV-irradiated TiO2-coated great enhancement flux very high retention for removal residual dye an aqueous feed solution....
We investigated adsorption of anionic surfactants, sodium dodecyl sulfate (SDS) and tetradecyl (STS), onto alumina (Al 2 O 3 ) with large size in the present study. The effective conditions for SDS STS Al were systematically studied. γ -Al optimized found to be contact time 180 min, pH 4, 1 mM NaCl. Adsorption both beads increased an increase ionic strength, demonstrating that is controlled by electrostatic attraction between groups positively charged surface, as well hydrophobic...
The need for analytical methods that are fast, affordable, and ecologically friendly is expanding. Because of its low solvent consumption, minimal waste production, speedy analysis, capillary electrophoresis considered a “green” choice among separation methods. With these features, we have utilized the method with capacitively coupled contactless conductivity detection (CE-C4D) to simultaneously determine glucosamine Ca2+ in dietary supplements. CE analysis was performed fused silica...
Antiretroviral therapy (ART) retention and 5 early-warning indicators (EWIs) of HIV drug resistance (HIVDR) were abstracted at 27 adult 4 pediatric clinics in Vietnam 2009. Of 4531 adults 313 children, 81.2% 84.4% respectively still on ART 12 months. More than 90% the monitored achieved World Health Organization (WHO) targets for lost-to-follow-up (LTFU), prescribing practices, ARV supply continuity. Only 83.9% met target first-line 79.3% clinic appointment-keeping. Clinic factors (i.e....
Abstract A series of x%Ag/ZnO (x: 0; 1; 2; 5; 10) nanostructures were successfully synthesized through the facile method. The material's structures confirmed X‐ray diffraction, while their morphology, elemental distribution, and components analyzed using cross‐sectional transmission electron microscopy (XTEM), Field‐emission scanning (FESEM). optical properties Ag/ZnO revealed a decrease in band gap from 3.2 eV to 2.83 significant reduction photoluminescence intensity with increasing Ag...
Abstract Highly positively charged poly(vinyl benzyl trimethylammonium chloride) (PVBMA) was successfully synthesized with approximately 82% of yield. The PVBMA characterized by the molecular weight ( M w ) 343.45 g mol −1 and distribution, Đ 2.4 1 H NMR SEC measurements. applied as an effective agent for α‐Al 2 O 3 surface modification in adsorptive removal azo dye acid orange G (AOG). AOG performance significantly enhanced at all pH compared to without modification. experimental parameters...
A method for the simultaneous determination of seven B-group vitamers including thiamine, riboflavin, nicotinamide, niacin, pyridoxine, pyridoxal, and pyridoxamine in nutritional products by using enzymatic digestion followed LC-MS/MS quantification was studied. The conditions such as MS transitions, mobile phase programs, ammonium formate buffer concentrations, sample treatment procedures (e.g., concentrations solution, temperature, time) were investigated. analytical performance evaluated...
Announced in 2010 at the International AIDS Conference Vienna and pioneered by Joint United Nations Programme on HIV/AIDS (UNAIDS) World Health Organization's (WHO) leadership global level, Treatment 2.0 is a new approach to HIV response that encourages innovation, efficiency, sustainability. Building upon WHO UNAIDS' "3 5" Initiative, focuses scale-up universal access of life-saving ART treatment through strategic investments innovations five priority pillars include: 1) Optimize drug...
The interzeolite conversion of faujasite (FAU-type) zeolites to chabazite (CHA-type) zeolite in the presence N,N,N-trimethyladamantammonium and N,N,N-dimethylethylcyclohexylammonium cations was investigated over a large compositional range by carefully controlling reaction mixture compositions. Highly crystalline CHA were also obtained transformation several types including EMT, LTL, LEV, RTH, MFI frameworks. formation from FAU precursors substantially faster than that L with similar...
Hedyotis diffusa Willd. is traditionally used in Vietnamese and Chinese medicine for its therapeutic properties.

The problems of global warming and sustainability, which are now causes for concern, will, in some way, have an impact on our lives. As a consequence increased focus ethical consumerism, rapidly developing countries such as Vietnam seeing change consumer behaviors well the marketing strategies used by corporations. This means that marketers must learn more about what makes people want to shop ethically. In particular, goal this research is explore psychological factors consumption habits...
Objectives: To study analgesic effects of basil extracts (Ocimum basilicum L.) on mice. Subjects and methods: The experiments were conducted according to heat stimulation (hot plate) needle slide methods. In each experiment, mice divided into 4 groups 10 each, in which the negative control group was given distilled water, positive one took drug, others treated with at doses 2.4 7.2 g/kg/day for 7 consecutive days. Mice drunk codeine phosphate 20 mg/kg or aspirin a dose 150 depending being...
Dichromate anions were intercalated between two consecutive hydroxide layers of [Mg0.6Al0.4(OH)2]0.40+ via co-precipitation at different pH conditions. The physico-chemical properties the obtained solids examined by physical methods such as X-ray diffraction (XRD), Infrared (IR), Scanning Electron Microscopy (SEM), Brunauer-Emmett-Teller (BET) and Energy-Dispersive Spectroscopy (EDS). experimental results indicated that amount dichromate in catalysts varies with media. Also, morphology,...
