attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
Addition of 0.5% onion was effective in reducing lipid oxidation in irradiated cooked ground beef after 7 day storage. Addition of garlic or onion greatly increased the amounts of sulfur volatiles from cooked ground beef. Irradiation and storage both changed the amounts and compositions of sulfur compounds in both garlic- and onion-added cooked ground beef significantly. Although, addition of g...
Dust is a common atmospheric phenomenon in Iran especially in central arid regions. This severely affects environment as well as resident’s health. Among the results of this phenomenon are Respiratory diseases, bash radiation, accelerated soil erosion, Desertification and degradation of ecosystems. Some dusts are originated from local desert conditions but adjacency to neighboring countries de...

In recent years, interleukin-2 (IL-2) has been used as an immunomodulatory agent in the treatment of various malignant tumours. However, this treatment has been limited by serious side-effects, including toxic reactions in the lung. The effects of IL-2 treatment on inflammatory cell populations in the normal and irradiated rat lung were investigated in this study. IL-2 was continuously administ...
testing plays a vital role in any language teaching program. it allows teachers and stakeholders, including program administrators, parents, admissions officers and prospective employers to be assured that the learners are progressing according to an accepted standard (douglas, 2010). the problems currently facing language testers have both practical and theoretical implications but the first i...
This paper presents a solar energy prediction method using artificial neural networks (ANNs). An ANN predicts a clearness index that is used to calculate global solar irradiation. The ANN model is based on the feed forward multilayer perception model with four inputs and one output. The inputs are latitude, longitude, day number and sunshine ratio; the output is the clearness index. Data from 2...
The Digital terrain model is an important geospatial product used as the basis of many practical projects related to geospatial information. Nowadays, a dense point cloud can be generated using the LiDAR data. Actually, the acquired point cloud of the LiDAR, presents a digital surface model that contains ground and non-ground objects. The purpose of this paper is to present a new approach of ex...
