This paper reports the temporal evolution of the scattering and absorbing cross-sections of marine eustigmatophycease Nannochloropsis oculata grown in a flat-plate photobioreactor (PBR). The PBR was operated in batch mode under constant irradiance of 7500 or 10,000 lux provided by red LEDs emitting at 630 nm. The radiation characteristics between 400 and 750 nm and pigment concentrations of N. ...
Genes of the major histocompatibility complex (MHC) play a central role in immune recognition, yet they also influence the odor of individuals. Mice can be trained to distinguish odors mediated by classical MHC loci; however, training can introduce confounding behavioral artifacts. This study demonstrates that mice can distinguish some, but not all, naturally occurring allelic variants at class...
Subtropical evergreen broad-leaved forest (EBLF) is one of the most important vegetation types in China. Inferences from palaeo-biome reconstruction (PBR) and phylogeography regarding range shift history of EBLF during the late Quaternary are controversial and should be reconciled. We compared phylogeographic patterns of three EBLF constituents in China, Castanopsis tibetana, Machilus thunbergi...
The impact of hexadecyltrimethylammonium bromide (CTAB) on the separation of ds-DNA by capillary electrophoresis in conjunction with laser-induced fluorescence (CE-LIF) detection using poly(ethylene oxide) (PEO) solution is described. The use of CTAB for improved separation reproducibility and efficiency of DNA has not been demonstrated although it is widely used for controlling the magnitude a...
به علت تشکیل ژل در پلیبوتادیان و برخی مشکلات مطرح شده از سوی صنایع لاستیکسازی مبنی بر وجود مشکل ترک شیار در محصولات، تعیین مقدار ژل و شناسایی ریزساختار الاستومر بوتادیان اهمیت بسیار زیادی دارد. در پژوهش حاضر، مقدار ژل در لاستیک پلیبوتادیان (PBR) با گرماسنجی پویشی تفاضلی معین شد. تجزیه گرمایی لاستیک پلیبوتادیان در محدوده دمایی ۰-۶۵ درجه سلسیوس به روشهای آزمون گرمایی بررسی و مطالعه شد. ت...
In this work, a modular millireactor (MMR) is designed and modeled using the computational fluid dynamics (CFD) tool OpenFOAM. First, method validated against conventional packed bed reactor (PBR) model (1D) with Aspen Plus. Next, applied to study effects of pressure (2–6 MPa) temperature (483–533 K) on performance MMR. Conjugate heat transfer (CHT) CFD results for MMR are compared correspondin...
Evolutionary dynamics model the changes in state of a population and strategies used by individuals population. One gets different based on types dependence fitness or revision protocols. In this paper we define Perturbed Best Response (PBR), Brown-von Neumann-Nash (BNN), Replicator Projection for stochastic games, using framework evolutionary games. We also class stable discuss their propertie...
In the USA, commercial fisheries that interact with marine mammals are categorised according to number of incidental takes relative defined Potential Biological Removal (PBR) for population. Three categories exist such fisheries: Category I, II and III, each varying in degree regulation. Fishery categorisation is based on a five-year running average entanglements fishery published annually Fede...
The hydrogenation of furfural is an important process in the synthesis bio-based chemicals. Copper-based catalysts favor to alcohols. Catalytic activity and stability were higher at a Ni-to-Cu atomic ratio 1:1 1.5:0.5 compared 0.5:1.5. Here, we prepared Ni-Cu/Al2O3 derived from layered double hydroxides (LDHs). Catalysts calcined 673 K reduced 773 with nominal Ni/Cu ratios y/x = 1.5/0.5, 1/1 0....
مقدمه: سرب یکی از چهار فلزی است که بیشترین عوارض را بر سلامت انسان دارد. با آنکه هیچ نقش حیاتی برای آن شناخته نشده، میتواند در سیستمهای زیستی آنقدر تجمع یابد تا به حد سمی برسد. سرب از طرق مختلف وارد محیط زیست میشود. یکی از روشهای سنجش آلودگی فلزات سنگین در محیط، زیست حسگر سلولی است که سلول حاوی یک ژن گزارشگر تحت کنترل پروموتر حساس به یک عامل (نظیر فلزات سنگین) میباشد. یکی از اپرونهای مهم...
