Investigation of gypsum-based historical materials has two main problems: philological problems and technical issues. Technical issues, the main topic of this article, are normally consequences of physicochemical complexity of gypsum crystals in different conditions and variety of additives or mixed materials. Neglecting this technical problem, leads researchers to misunderstand or misinterpret...
In order to evaluate the relationship between SDS-sedimentation value and breadmaking quality of wheat (Triticum aestivum L.), glutenin subunits of different genotypes (foreign and Iranian cultivars) were analyzed by reverse-phase high performance liquid chromatography (RP-HPLC). SDS-sedimentation value was used as an indirect criterion for breadmaking quality. Correlation coefficients revealed...
THE purpose of the studies described in this paper has been to lay the groundwork for the development of a technique for analytical medium-speed centrifugation in which quantitative separation of nuclei, whole cells, mitochondria, mirrosomes, soluble proteins, and lipid inclusions may be achieved in one or t\\-o steps. Since it is not possible, at present, to make quantitative measurements of a...
Introduction and purpose: Groundwaters provide the main source of drinking water in Mazandaran province; however, the high concentration of soluble salts and hardness in these waters result in probable sedimentation and corrosion in water distribution systems of these areas. Therefore, the aim of this study was to determine the sedimentation and corrosion potential in the drinking water resourc...
Abstract: Hardfacing is one of the most useful and economical ways to increase the service life of components subjected to abrasive wear. Iron based hardfacing alloys have long been considered as candidate coatings for wear-resistant applications in industry. In the present work two layer of Fe-34Cr-4.5C%wt hardfacing alloy was deposited on ASTM A36 carbon steel plates by SMAW method. The m...
Estimation of annual erosion and sedimentation in Babolroud catchment using EPM and Fournier methods
One of the problems of controlling erosion and sedimentation in catchment areas is the lack of statistical data to accurately estimate the amount of sedimentation and erosion. In order to implement soil protection programs and determine methods to reduce sedimentation, it is necessary to estimate the total volume of annual sediment production. The purpose of this study is to estimate the erosio...
sedimentation is one of the most important problems in harbors that results in considerable economic costs. harbor planforms affects the flow pattern in the harbor basin and consequently, plays an important role in sediment transport and sedimentation. in the present study, a two dimensional depth-averaged hydrodynamic and sediment transport model has been developed to investigate the effect of...
In this paper, a non-destructive eddy current test system was designed to evaluate the surface hardness of the carbonitrided steel parts. For this purpose, various samples of the tappet were used after the surface hardening and grinding operations as control samples and, if necessary, were subjected to destructive and non-destructive tests. Microstructural studies were performed with a microsco...
