Current earth observation models do not take into account the influence of water salinity on the evaporation rate, even though the salinity influences the evaporation rate by affecting the density and latent heat of vaporization. In this paper, we adapt the SEBS (Surface Energy Balance System) model for large water bodies and add the effect of water salinity to the evaporation rate. Firstly, SE...
Abstract This article investigates changes in student teachers’ teacher self-efficacy beliefs (SEBs) as part of their competence development during three-year bachelor’s program and how these can be explained through practical learning opportunities. Using two cohorts who studied prior to COVID-19, differences the are analyzed longitudinally over three time points. Unexpectedly, no increase SEB...
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...
کمبود آب یکی از ویژگی های بارز مناطق خشک است. ایران مرکزی یک منطقه کم آب است که در آن اطلاع دقیق از منابع آب، میزان مصرف آن برای مدیران بسیار حائز اهمیت است. منطقه مورد مطالعه در این تحقیق شامل محدوده شهرهای یزد، اشکذر و مناطق اطراف آن می باشد و مساحت آن 726 کیلومتر مربع است. مختصات جغرافیایی این منطقه شامل طول شرقی 64/54 تا 09/54 درجه و عرض شمالی 06/32 تا 73/31 درجه است. خشکی بیش از حد این منط...
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...
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...
Wearable flexible electronic strain sensor devices have developed rapidly in recent years due to their potential capacity detect human motion various situations. However, it still remains a big challenge fabricate sensors with high sensitivity over wide workable range. In order meet this challenge, new type of based on elastomer/carbon nanotube composite fiber is reported work. Elastomer fibers...
