Evapotranspiration (ET) plays an important role in the hydrological cycle and it is essential to estimate ET accurately for the evaluation of available water resources in arid regions. In this paper, the monthly change of ET in the semi-arid Hailiutu River basin in northwest China were studied. The spatial distribution of ET was assessed by using the energy balance approach SEBS (Surface Energy...

If G is a looped graph, then its adjacency matrix represents a binary matroid MA(G) on V (G). MA(G) may be obtained from the delta-matroid represented by the adjacency matrix of G, but MA(G) is less sensitive to the structure of G. Jaeger proved that every binary matroid is MA(G) for some G [Ann. Discrete Math. 17 (1983), 371-376]. The relationship between the matroidal structure of MA(G) and t...

Poly(vinyl chloride) (PVC) and natural fiber composites were prepared by melt compounding and compression molding. The influence of fiber type (i.e., bagasse, rice straw, rice husk, and pine fiber) and loading level of styrene-ethylene-butylene-styrene (SEBS) block copolymer on composite properties was investigated. Mechanical analysis showed that storage modulus and tensile strength increased ...

Hybrid anion exchange membranes (AEMs) were prepared via chemically functionalizing and crosslinking poly(styrene-b-[ethylene-co-butylene]-b-styrene) (SEBS) copolymers low molecular weight homo-polystyrene (hPS). Via sequential chloromethylation, crosslinking, quaternization, alkalization, a series of hPS/SEBS AEMs obtained with varying content hPS. Systematic structural, morphological, mechani...

We report a facile approach to prepare MoS2 nanosheet coated TiO2 nanobelts. The TiO2@MoS2 structure exhibits a reversible capacity of 710 mA h g(-1) at 100 mA g(-1) after 100 cycles with highly stable capacity retention, and bears good rate capability with a reversible capacity of 417 mA h g(-1) at 1000 mA g(-1).

A method is described for cutting DNA at specific sites that are 8 and 10 base pairs long. The DNA is first treated with a specific methylase, either the restriction-modification enzyme M. Taq I, which converts the 4-base sequence T-C-G-A to T-C-G-mA, or the similar enzyme M. Cla I, which converts the 6-base sequence A-T-C-G-A-T to A-T-C-G-mA-T. The DNA is then cleaved with Dpn I, a restriction...

The inquiry-based learning model can facilitate students’ understanding of scientific concepts. Scientific epistemological beliefs (SEBs) are related to about the nature process knowledge in science education. However, whether “prediction-observation-explanation” (POE) fifth graders’ concept achievement and SEBs education has not been extensively studied. This study selected unit Light Refracti...

In spite of the well-established design and construction approaches slag–cement–bentonite slurry walls, materials deteriorate inevitably in contaminated land. The development effective which are sustainable, resilient self-healing over lifetime walls becomes essential. This study, for first time, adopts a styrene–ethylene/butylene–styrene (SEBS) polymer to modify enhance mechanical performance....

In this work, a recently developed 3D additive processing technology termed electrohydrodynamic (EHD) printing was employed to fabricate dielectric elastomer (DE) films by using styrene-ethylene-butylene-styrene (SEBS) inks with the addition of high titanium dioxide (TiO2) nanoparticles. order improve dispersibility TiO2 in SEBS matrix, extracted walnut polyphenols were utilized for surface mod...
