In the past the earthen materials were accounted as the most widely used materials both structurally as well as finishing of traditional and historical buildings in urban and rural areas across the country. However, due to the wear and tear and lack of resistance to humidity and subjected loads, the roof and the walls covered with thatch mortars need to be annually reconstructed and repaired, w...
the present work is an experimental study of steady state convective heat transfer of de-ionized water with a (0.04% by volume) volume fraction of al2o3 nanoparticles dispersed to form a nanofluid that flows through an aluminium tube.laminar fully developed flow heat transfer coefficient of al2o3 nanoparticles are dispersed in water in circular tube is discussed in this paper. in order to valid...
A simple and solvent-minimized sample preparation technique based on hollow fibre-protected liquid-phase micro-extraction has been developed for extraction of fifteen organic sulphur compounds from aqueous samples. The analysis of the extracted them was performed by gas chromatography equipped with mass spectrometry and/or flame photometric detectors. 3.3 µL of organic solvent located in the lu...
this work presents a model for calculating the effective thermal conductivity of nanofluids. the proposed model includes the effects of nanoparticles and thermal conductivity base fluid.we will focus on experimental of the volume concentration parameter and temperature on thermal conductivity, nano-fluid combination and multi-walled carbon nanotubes-oxide / copper-paid deionized water. th...
The excessive focus on water mounts a challenge to the sustainable development. Energy is another aspect that should be taken into account. Nexus approach is characterized by an equal emphasis on energy and water spheres. In arid areas, like the city of Kashan, Iran, non-conventional waters (e.g. desalinated and recycled waters) have been considered as an alternative resource of water. Nexus wa...
The variation and path coefficient analysis of bread-making quality traits have been studied for 145 genotypes of breeding lines, cultivars and landrace varieties of wheat (Triticum aestivum L.). Bread-making quality traits of genotypes was evaluated indirectly by protein percentage, SDS and Zeleny sedimentation tests, hardness index, test weight, bread volume, grain moisture, and water absorpt...
mixed convection of al 2 o 3 -water nanofluid in a square microcavity is investigated numerically. governing equations are discretized and solved using the finite volume method and simpler algorithm. the knudsen number is selected between 0.001 and 0.1 to consider slip velocity and the jump temperature boundary conditions. results showed that nusselt number is a function of richardson number, k...
Improvement of bread quality in bread wheat (Triticum aestivum L.) depends on a thorough understanding of the genetic basis of important quality traits. Therefore, this study was conducted to investigate the genetic basis of wheat grain quality traits including kernel length, kernel width, 1000-kernel weight, grain protein content, Zeleni No, bread volume, moisture content, grain hardness, wate...
in this work the conduction of ion-water solution through two discrete bundles of armchair carbon and silicon carbide nanotubes, as useful membranes for water desalination, is studied. in order that studies on different types of nanotubes be comparable, the chiral vectors of c and si-c nanotubes are selected as (7,7) and (5,5), respectively, so that a similar volume of fluid is investigated ...
