“…In turn, culture learning is seen not as the acquisition of facts, but as a constructivist process…as a systematic and integral part of language learning, rather than an add-on. (Social Science Education Consortium, 1999, p.10) Richmond (1992) posits that "culture produces both typical ways of behaving and typical expectations concerning others' behavior", and defines culture "as a human society's standards of verbal and nonverbal communication that define a range of behavior acceptable in that society"…”

The purpose of the present study is to examine home culture attachment construct and its underlying variables among Iranian English as Foreign Language learners as well as their attitudes towards English language learning. Pearson correlation is used with a sample of 411 English major university students from different provinces in Iran, mainly Khorasan Razavi, Khoran Jonoubi and Sistan Baluchestan participated in this study. As for the quantitative phase of data collection, the study employed home culture attachment and attitude towards English language learning questionnaires. The reliability and validity of these questionnaires are reported. A home culture attachment model and an attitude model are also developed and tested using structural equation modeling. The results suggest that all three subscales of attitudes (emotional, behavioral, and cognitive) are positive and significant predictors of students' western attachment. From three subscales of attitude, only behavioral attitude is negative and significant predictors of students' religious attachment. In addition, Iranian attachment is influenced by cognitive attitudes and emotional attitudes. Besides, cognitive attitude is a positive and significant predictor of students' cultural attachment. It is also found that, artistic attachment is influenced by behavioral attitudes and emotional attitudes. Finally, the pedagogical implications are discussed in light of foreign language achievement.

Abstract:In this study, growth performance, haematological and non specific immune system parameters of Nile Tilapia (Oreochromis niloticus L., 1758) fed with diets which contain different levels of (0; 5.0; 7.5 and 10.0 g/kg) spirulina (Spirulina platensis) were investigated. At the end of the feeding experiment (75 days), total erythrocyte (RBC) and leukocyte counts (WBC), hematocrit (Hct), hemoglobin (Hb), leukocyte cell types (monocyte, lymphocyte, neutrophil, eosinophyl), RBC indices (MCV, MCH, MCHC) and phagocytic activity of blood taken from fish were determined in a certain period. According to the results, the addition of 5.0 g/kg spirulina in diet highly increased the phagocytic activity of neutrophils and monocytes and also the addition of 7.5 g/kg of spirulina in diet increased the amounts of RBC and WBC.Consequently, these two levels of spirulina can be used as a protective agent against diseases by supporting the fish immune system.

Cyanobacteria are phototrophic aquatic micro-organisms that are found in a variety of environments, including polluted ones. Fifteen strains of cyanobacteria that belong to three taxonomic groups are able to degrade lindane (λ-hexachlorocyclohexane, a recalcitrant pesticide). The initial degradation pathway has been studied in two filamentous nitrogen-fixing strains of Anabaena sp. PCC 7120 and Nostoc ellipsosporum. These cyanobacteria dechlorinated loindane first to pentachlorocyclohexene and then to a mixture of trichlorobenzenes, and possibly further. Lindane dechlorination by these organisms occurred only in the presence of nitrate in the medium. Both ammonium and darkness inhibited the process. This combination of observations led us to the hypothesis that the nitrate-reduction system of cyanobacteria may be involved in dechlorination. The hypothesis was proven by the analysis of Anabaena sp. transpositional mutants in four genes of the nir operon. The mutants were unable to dechlorinate lindane. However, there was no correlation between lindane dechlorination and activities of individual proteins encoded by this operon. Genetic engineering of Anabaena sp. and N. ellipsosporum that introduced linA lindane dechlorination operon from Psuedomonas paucimobilis allowed us to uncouple dechlorination from nitrate requirement. Introduction, by genetic engineering, of fcABC (the 4-chlorobenzoate dechlorination system from Arthrobacter globiformis) to Anabaena sp and N. ellipsosporum rendered these strains newly capable of 4-chlorobenzoate dechlorination both constitutively and inducible by an environmental factor.
