the performance of a γ-al 2 o 3 /n-decane nanofluid shell-and-tube heat exchanger in a biomass heating plant is analyzed to specify the optimum condition based on the maximum heat transfer rate and performance index for wide range of nanoparticle volume fraction (0–7%). compared with pure n-decane, the obtained results in this research show that by using γ-al 2 o 3 /n-decane nanofluid ...
AIM The study was undertaken to find out the physicochemical characteristics, selected processing-related parameters and activity of selected enzymes in Surti goat milk. MATERIALS AND METHODS Milk samples from Surti goats and buffalo milk samples were collected during the period from July 2013 to January 2014 at Reproductive Biology Research Unit, Anand Agricultural University (AAU), Anand. M...
In the context of bio-based ionic liquids (ILs), in recent years levulinate ILs have been explored various applications with appreciable performances. To expand their scope use, seven selected featuring different cationic moieties prepared and physico-chemical properties compared. While all generated displayed only glass transitions at low temperature (<−60 °C), [C4C1Pyr]Lev presented melting c...
This study was conducted to evaluate the gene effects, heritability, heterosis and identification of appropriate breeding methods for improving rice viscosity parameters, during 2014-2016 at Rice Research Institute of Iran. The progeny obtained from the North Carolina III mating design with their parents were planted in a randomized complete block design with three replications. Analysis of var...

in this project, some new polyaspartimides, (pas)s, have been synthesized form michael addition reaction between new synthetic bismaleimide (bmi) and some aromatic diamines. a characteristic property of this polyaspartimides is a pendent carboxylic group, which introduced to these polymers from new bismaleimide. bismaleimides (bmi) is one of the interesting compounds, which can be self-polymeri...
This study aimed to determine how various concentrations of warm mix asphalt (WMA) additives can affect the rheological and physical characteristics cement. Bitumen was modified by chemical additive PAWMA® with an addition ratio (0.2, 0.4, 0.6), while organic additives, Sasobit® Kaowax®, were added at (2, 4, 6%) weight bitumen. hardness, softness, temperature susceptibility, viscosity, elastic ...
