the present study was an attempt to investigate varieties of cloze test and c-test as measures of reading comprehension ability. it aimed at comparing the performances of subjects on different cloze and c-test forms constructed from the same passage. to this end, five versions of cloze test and two versions of c-test were developed by applying different deletion techniques and deletion rates, a...

Composting is considered an efficient and environmentally friendly alternative for plant waste management, resulting in compost, a high value-added product. During the process, microorganisms play crucial role as organic matter-degrading agents. However, highly recalcitrant nature of lignocellulose present residues sets challenge to involved process. Therefore, objective this study was evaluate...

A simple experimental set-up was used to study the treatability aspect of phenolic wastewater. Three types of systems: i) activated sludge (A.S), ii) granular activated carbon (A.C) and iii) activated sludge plus activated carbon (A.S + A.C) were experimented under different phenol loadings (100, 200 and 300 mg/l) and different flow rates (21.6 and 43.2 l/d) with initial COD concentration 500 m...

Myelin injury in multiple sclerosis (MS) has been attributed both to "outside-in" primary immune mediated and "inside-out" metabolic stress of oligodendrocyte (OL) related mechanisms. Subsequent remyelination is dependent on recruitment and differentiation of oligodendrocyte progenitor cells (OPCs). RNS60 is a physically-modified saline containing charge-stabilized nanobubbles generated by subj...

A mathematical dynamic model describing biological removal of high loads of H2S from biogas streams through a biotrickling filter (BTF) was developed, calibrated and validated to a range of specific experimental conditions of a lab-scale BTF. This model takes into account the main processes occurring in the three phases of the desulfurizing BTF (gas, liquid and biofilm phase) in a co-current co...

The aim of this work is to evaluate the influence of cyclophosphamide and its principal metabolites (CPs) on microbial behaviour in a membrane bioreactor system. Two laboratory-scale membrane bioreactors (MBR) were run in parallel with a sludge retention time of 70 days (one with the cytostatic drugs, MBR-CPs, the second without, MBR-control). The microbial activity was measured by respirometri...
