Two different grades, WC-20 vol.% Ni and Co cemented carbides, respectively were systematically investigated concerning their microstructure, binder composition, corrosion behavior. SEM-EBSD analysis verified that both grades have similar WC grain sizes (0.9–1.1 μm). AES confirmed the phase of respective grade is an alloy Ni-W Co-W concentration W in Ni- Co-binder 21 10 at. %, respectively. In ...

The present study aims to investigate the potential of multi-configuration Sentinel-1 (S-1) synthetic aperture radar (SAR) images for characterizing four wheat parameters: total fresh mass (TFM), dry (TDM), plant heights (He), and water content (WC). Because they are almost independent on weather conditions, we have chosen use only SAR. Samples parameters were collected over seven fields (three...

Interest has increased recently in water recycling and reuse. The possible economic feasibility of reuse and recycling dramatically increases th}complexity of designing a optimal water delivery s stem. In this •a•c•: wc p;csc:.;., ii6,ii•;i,• ..... ud,•i -,ich takes into account both flow requirements and water quality. Because of the model's transshipment formulation the solution technique see...

Salt meadow on lake beaches is the most dynamic plant community. Studying its soil characteristics and response threshold allows us to understand external driving forces of vegetation stable-state maintenance changes, provide a theoretical basis for utilization ecological restoration beach wetland resources. In this study, community diversity, physical chemical properties soil, thresholds key i...

in this research, some of the echo-physiological characteristics of pistachio trees were studied to understand crop response to drought stress and determine the best irrigation interval. this experiment was carried out in an orchard with a sandy loam textured soil and a commercial cultivar of pistachio named ouhadi grafted on pistacia vera l. rootstock for three years. the irrigation system sel...

In commercial pigs, the greatest susceptibility for pre-weaning mortality occurs in low birth-weight piglets. Despite their overall decreased birth weight, Meishan (MS) piglets have decreased pre-weaning mortality rates compared with contemporary Western breeds. The objective of the current study was to determine the contributions of the maternal uterine environment, piglet genotype, and their ...

In this work, various microcrystalline celluloses were extracted from apricots shells (AC) and walnut (WC) by alkaline treatments combined with hydrogen peroxide blanching. Different composites-based poly (lactic acid) (PLA) cellulose PLA/AC PLA/WC successfully prepared the cast-solution method ratios. PLA composites characterized tensile test, Fourier transform infrared spectroscopy (FTIR), me...

This study focuses on a comparative analysis of mechanical behavior and microstructural characteristics Cu matrix (C87600) based hybrid composites reinforced with SiC-Grp WC-Grp fabricated by the stir casting process. The graphite particle percentage was kept constant, whereas content SiC WC in respective varied to analyze properties composites. morphological observation carried out field emiss...

This experiment tested the role of oropharyngeal and gastric afferents on hypothalamic activation in dehydrated rats instrumented with gastric fistulae and allowed to drink water or isotonic saline compared with euhydrated controls (CON). Rats were water deprived for 48h (48 WD) or 46h WD with 2h rehydration with water (46+W) or isotonic saline (46+S). 46+W and 46+S rats were given water with f...

Monitoring coherently the Amazon Water Cycle (WC) using satellite observations is crucial for climate and water resources studies. The SAtellite (SAWC) integration methodology introduced to optimize datasets. In this paper, WC budget balanced simultaneously over 10 sub-basins by constraining horizontal exchanges between them. Compared an actual assimilation analysis, SAWC benefits from use of s...
