[1] By partitioning mass and energy fluxes, soil moisture exerts a fundamental control on basin hydrological response. Using the design characteristics of the Biosphere 2 hillslope experiment, this study investigates aspects of soil moisture spatial and temporal variability in a zero‐order catchment of a semiarid climate. The hydrological response of the domain exhibits a particular structure, ...
900°C for 1hr after melting in air. These high permeability alloys have been named "Nimalloy." It is not considered, however, that the alloys are sufficiently homogenized by these treatments since a large discrepancy between the solidus and liquidus lines in the Ni-Mn system may result in tremendous segregation of the alloys on solidifying. Therefore, homogenization and purification of the allo...
The aim of this study was to investigate the preparation of oil-in-water (O/W) nanoemulsions using an emulsification–evaporation process. Nanoemulsions were formed by homogenizing 10 wt% of an organic phase composed by corn oil and hexane mixed at different ratios, and 90 wt% emulsifier solution containing 1.0 wt % of Tween 20 (T20) or β-lactoglobulin (β-Lg). Nanoemulsions were prepared using a...
in this study, a simple, rapid and selective method was developed for the determination of dexamethasone. the proposed method is based on inhibitory effect of dexamethasone on the oxidation of orange-g by bromate in sulfuric acid media. the reaction was followed spectrophotometrically at 478.5 nm (?max). under optimum experimental conditions, (72.6 ?mol l-1 of orange-g, 0.76 mol l-1 of h2so4, 0...
Abstract In this study, the chemical precipitation coating (CP) process was creatively integrated with DLP-stereolithography based 3D printing for refining and homogenizing microstructure of printed Al 2 O 3 ceramic. Based on novel approach, powder coated a homogeneous layer amorphous Y , found to make ceramic more uniform refined, as compared conventional mechanical mixing (MM) powders. The gr...
In this research, we demonstrate a high-sensitivity integrated silicon nitride long period grating (LPG) refractometer based on rib waveguide with sinusoidally modulated width. While LPG architectures typically achieve ultrahigh sensitivity only over narrow optical bandwidth using phase-matching turning-point optimization technique, our sensor exhibits very high refractometric that was designed...
Determination of the effective elastic properties unidirectional short fiber reinforced composites (SFRCs) is a key fundamental requirement which usually estimated by mean-field homogenization (MFH) methods. Available classical MFH methods only account for volume fraction and aspect ratio fibers do not consider physical cylindrical geometry fibers. Moreover, MFHs are designed predicting SFRCs w...
We demonstrate that the rapidity and robustness of slow contraction in homogenizing flattening universe found simulations which initial conditions were restricted to non-perturbative variations described by a single fourier mode along only spatial direction are general enhanced if two directions, include multiple modes, thereby have reduced symmetry. Particularly significant shear effects becom...
Material culture worked as an essential supporting pillar of the ancient Egyptian colonization Nubia. During New Kingdom colonial period (1550–1070 BCE), material various sites in Nubia consisted a majority Egyptian-style objects (including both imported and locally produced objects). materialized foreign presence local contexts allowed communities to negotiate identities positions situation. H...
Population differentiation often reflects a balance between divergent natural selection and the opportunity for homogenizing gene flow to erode the effects of selection. However, during ecological speciation, trait divergence results in reproductive isolation and becomes a cause, rather than a consequence, of reductions in gene flow. To assess both the causes and the reproductive consequences o...
