the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
since the 1960s the age effects on learning both first and second language have been explored by many linguists and applied linguists (e.g lennerberg, 1967; schachter, 1996; long, 1990) and the existence of critical period for language acquisition was found to be a common ground of all these studies. in spite of some common findings, some issues about the impacts of age on acquiring a second or...
The effects of microwave pretreatment on disintegration and mesophilic digestion of waste activated sludge (WAS), primary sludge (PS), combined (PS + WAS) sequencing batch reactor (SBR) sludge and anaerobically digested biocake were investigated by both household and bench scale industrial types microwaves at temperatures below and above boiling point. Pretreatment variables, temperature, inten...
The behaviors of the Macrolide-Lincosamide-Streptogramin (MLS) resistance genes were investigated in an anaerobic-aerobic pilot-scale system treating spiramycin (SPM) production wastewater. After screening fifteen typical MLS resistance genes with different mechanisms using conventional PCR, eight detected genes were determined by quantitative PCR, together with three mobile elements. Aerobic s...
In India, Pulp & paper industries have been large uses of portable water and consequently large generator of waste water. Anaerobic treatment of paper processing waste water has a distinct advantage of recovery of inherent energy in the form of methane gas with much less sludge production. A hybrid reactor that capitalizes on the positive features of anaerobic filter(AF) and up-flow anaerobic s...
Work was focused on possibilities of biogas production from a crude glycerol. This material is by-product of biodiesel production. In the work results of crude glycerol treatment in the laboratory mixed reactor and in the laboratory UASB reactors are described. Results from long-term co-digestion of maize silage and crude glycerol in full scale anaerobic reactor at biogas plant are also discuss...
The wastewater discharged by poultry slaughterhouse industries are characterized mainly by high biochemical oxygen demand, high suspended solids and complex mixture of fats, proteins and fibers requiring systematic treatment prior to disposal. In this study, the performance of an upflow anaerobic filter reactor for treating Indian poultry slaughterhouse wastewater under low upflow velocity of 1...
In this study, various chemical and advanced oxidation processes were tested for enhancement of anaerobic biodegradation of olive mill effluent (OME). The experiments were carried out in a 20 L lab-scale ACF reactor packed with cross-flow filter material made of water-resistant cardboard with a specific surface area of ~300 m m. The ACF reactor was operated at chosen OLR conditions and fed with...
this study was conducted to investigate the impact of podcasts as a learning and teaching tool on iranian efl learners’ motivation for listening as well as on their listening comprehension ability. the study also investigated the learners’ perception towards listening to podcasts and examined whether the learners were likely to accept podcasts. out of fifty-five intermediate learners studying e...
Pabrik Tahu Kumpai Kecil merupakan salah satu industri skala kecil di Kecamatan Sungai Raya, Kabupaten Kubu yang menghasilkan air limbah tahu dibuang ke badan tanpa diolah dahulu. Sampel diambil dengan cara komposit waktu. Debit diukur secara volumetrik menampung pada gelas takar sehingga diperoleh debit rata-rata harian untuk perencanaan sebesar 1,8 m3/hari. Hasil uji kualitas menunjukkan semu...
