Land use and cover change (LUCC) has a non-negligible impact on both carbon emissions sinks. Based the analysis of land dynamics in Shandong Province, this study simulates changes Province 2030 under Natural Development Scenario (NDS) Sustainable (SDS), classifies risk level using Use Carbon Emission (LUCE) indexes, compares differences between regions NDS SDS. This shows that influence LUCC, p...
Hydrate-based gas separation is a potential technology for CO 2 recovery and storage, its products can be used fire prevention control in mines. Promoters are often employed to accelerate or moderate hydrate formation. In this study, experiments were performed examine the effects of different concentrations thermodynamic promoter tetrahydrofuran (THF) kinetic sodium dodecyl sulphate (SDS) on fo...
Abstract A novel nitrogen-doped carbon quantum dots (N-CDs) were prepared by the microwave irradiation method. The fluorescence quenching effect of Co(II) on N-CDs was studied in sodium dodecyl sulfate (SDS) medium and sensitized SDS. linear range calibration curve for determination 0.17µg/mL-11.8µg/mL limit detection 0.052µg/mL. method has been applied samples with satisfactory results.
BACKGROUND We recently reported the age interval 2-6y being the earliest and most critical for adult overweight. We now aim to determine which age intervals are predictive of cardiometabolic risk at young adulthood. METHODS AND FINDINGS We analyzed data from 642 18-28 years olds from the Terneuzen Birth Cohort. Individual BMI SDS trajectories were fitted by a piecewise linear model. By multip...
The 29,000-Mr Actinomadura R39 beta-lactamase exhibited a remarkably low electrophoretic mobility on SDS/PAGE, yielding an Mr value almost twice that computed from the corresponding gene sequence. We showed that chemical modification of the carboxylic groups of glutamic acid and aspartic acid residues restored a normal electrophoretic mobility and that the anomalous behaviour of that protein on...
OBJECTIVE To determine the impact on final adult height of bone marrow transplantation. METHODS The final height of 28 long term survivors (18 males; 10 females), allografted before or at the onset of puberty, at a median age of 10.8 years (range 6.3 to 14.6) and who did not receive growth hormone (GH) treatment or other growth promoting agents, was evaluated. Median follow up period after bo...
The present studies were undertaken to develop solvent-free solid dispersions (SDs) for poorly soluble anti-inflammatory drugs mefenamic acid (MA) and flufenamic acid (FFA) in order to enhance their in vitro dissolution rate and in vivo anti-inflammatory effects. The SDs of MA and FFA were prepared using microwaves irradiation (MW) technique. Different carriers such as Pluronic F127® (PL), Eudr...
اهداف: فنل و مشتقات محلول آن در آب از مهم‌ترین و متداول‌ترین آلاینده‌های سمی و خطرناک متاثر بر سلامت عموم افراد در جامعه هستند. این مطالعه با هدف بررسی فرآیند نانوفتوکاتالیکی نانواکسید روی/تابش فرابنفش بر تجزیه فنل محلول در آب انجام شد. مواد و روش‌ها: برای انجام این مطالعه تجربی- آزمایشگاهی ابتدا نمونه‌های فاضلاب مصنوعی محتوی فنل با غلظت‌های اولیه 50، 100 و 200میلی‌گرم بر لیتر درون یک راکتور از...
