The ruins of impressive structure made by adobe known as the city of “Belgheis” is located 3 km from Esfarayen in the province of North Khorasan of Iran. The role of soil quality in the occurrence of damages to clay and adobe structures of Belqis area is the purpose of this research. Choosing the right soil is the first step in the preparation of adobe, Therefore, it is necessary to study the r...
background: chemical weapon victims are suffering from physical difficulties and psychological trainings may help to decrease these problems. the purpose of this research was to examine the effectiveness of mindfulness and emotion regulation training on physical and psychological well-being in chemical weapon victims. methods: an experimental, pre-post and follow-up study designed. forty seven ...
Sieve Residue Sieve residue refers to non-dispersable contaminants (such as coke, refractory particles, water soluble salts and metal oxides) and is expressed as a percentage of the carbon black by weight. Sixty and 325 Mesh sieves are used for this test. The resulting grit can cause blemishes and may affect the appearance and performance of some rubber and plastic products. The 325 Mesh grit i...
In this paper a two impinging streams cyclone contacting system suitable for handling of solid-liquid systems has been studied. Certain pertinent parameters such as: solid holdup, mean residence time and Residence Time Distribution (RTD) of solid particles have been investigated. A stochastic model based on Markov chains processes has been applied which describe the behavior of solid partic...
The physical and chemical properties of Pyrazole and Pyrazoline molecules were theoreticallystudied by Gaussian 03, software with NMR and Molecular orbital calculations at B3LYP/6-31G andB3LYP/6-31+G(d) levels, in gas phase and solution. In this study a comparison effect of threesolvents with different dielectric constants on Pyrazole and Pyrazoline molecules in aspect energyinteraction between...
The design of high performance computing systems requires many design decisions based on performance, cost, power consumption, and possibly other criteria. Decisions made in the early, high-level speciication phase are critical to developing a successful product. We describe a methodology which allows the architect to explore alternatives at all design levels for diierent technology options. We...
The microscopic and macroscopic characters of the leaves, physical constant values, behavior on treatment with different chemical reagents, fluorescence characters under ultra violet light after treatment with different chemical reagents of the powdered leaves of Azadirachta indica A. Juss (Family-Meliaceae) were studies to fix some pharmacognostical parameters.
The macroscopic character of the roots physical constant values, extractive values, behaviour on treatment with different chemical reagents, fluorescence characters under ultra violet light after treatment with different chemical reagents of the powdered roots of Asparagus racemosus Willd, (Fam. Liliaceae) were studied to fix some pharmacognostical parameters.
The macroscopic characters of L. lavandulaefolia, physical constant values, behaviour on treatment with different chemical reagents, fluorescence characteristics after treatment with different chemical reagents of the powder of L. Lavandulaefolia were studied to fix some pharmacognostical parameters. Preliminary phytochemical studies and TLC characterization of different extractives has also be...
The macroscopic character of the whole plant, physical constant values, extractive values, behaviour on treatment with different chemical reagents. Fluorescence characters under uv light after treatment with different chemical reagents of the powdered whole plant of lonidium suffruticosam Ging (Family; violaceae) were studied to characterize some pharmacognostical parameters. Preliminary photoc...
