Increasing spread of information and communication technology and the deep impact of it on all aspects of society, including jobs and careers, have led to the emergence of teleworking. Teleworking has been deployed in most of the developed countries, and has created a significant added value for their societies therefore, developing countries must prepare themselves for teleworking and its vari...

the aim of this paper is eliminating cr(vi) by natural hap. hap is a inexpensive material which is used from bovine critical bone ash in order to remove heavy metal ions like cr(vi). some experiments in different ph are performed (ph=2,3,7). maximum adsorption was appeared at ph=2, dosage=0.3 gr, c0=10 mg/l. cr(vi) removal depends on ph value and initial amount of cr(vi) result of experiments w...

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...

Developing societies are, for a number of reasons, suffering from some sort of national inefficiency. Causes of inefficiency are cultural,deep-rooted and numerous. Since the developed countries, using all possible facilities, are moving rapidly toward the highest levels of efficiency, the international dimensions of that inefficiency become more extensive together with deeper consequences.In o...

the purpose of this thesis was to investigate how differently metacognitive, cognitive, and social/affective strategies affect l2 learners’ reading comprehension. to this end, the study employed a quasi-experimental design with a placement test as a proficiency test to find the homogeneity of groups. three classes were randomly selected as the experimental groups (n =90), and each class was tau...
