The study focused on the comparative correlative Test Rubrics Used as Benchmarks in Assessing International English Language Testing System (IELTS) and of a Foreign (TOEFL) Speaking Skills. To carry out this project, researcher searched for IELTS TOEFL candidates recruited finally selected 37 male female who took both standard tests various reasons. statistical results obtained (mainly Pearson&...

Iodometric Back Titration (IBT) and Spectrophotometric (SPM) determination are two commonly used methods for the determination of hydrogen sulfide (H2S) concentration in sea water. These two methods were applied in parallel for analysis of Black Sea anoxic waters and artificial solutions containing different H2S concentrations. The results of the SPM and IBT methods are in agreement when the H2...

Many populations are composed of a mixture of individuals that reproduce at different times, and these times are often heritable. Under these conditions, gene flow should be limited between early and late reproducers, even within populations having a unimodal temporal distribution of reproductive activity. This temporal restriction on gene flow might be called "isolation by time" (IBT) to ackno...

due to the high penetration of wind farms in the networks, they can have a significant role in the control of power systems. in this paper, wind farms (wfs) are used to improve the static security margins of the power system. generation rescheduling is one of the remedies to improve the static security margins of the power system. in this paper, the generation rescheduling is presented based on...

Regional water supply systems undergo surplus and deficit conditions due to differences in inflow characteristics as well as due to their seasonal demand patterns. This study proposes a framework for regional water management by proposing an interbasin transfer (IBT) model that uses climate-informationbased inflow forecast for minimizing the deviations from the end-of-season target storage acro...

Island Biogeography Theory (IBT; MacArthur and Wilson 1963, 1967) has profoundly infl uenced the study of biogeography, ecol ogy, and even evolution (Janzen 1968, Losos 1996, Heaney 2000), and has also had an enormous impact on conservation biology. The theory has inspired much thinking about the importance of reserve size and connectivity in the maintenance of species diversity, and stimulated...

The interaction between isatin-β-thiosemicarbazone (IBT) and calf thymus DNA (CT-DNA) was investigated in physiological buffer (pH 7.4) using Neutral Red (NR) dye as a spectral probe by UV–Vis absorption and fluorescence spectroscopy, as well as viscosity measurements. The IBT is stabilized by intercalation in the DNA ( K [IBT –DNA] =1.03×105 M−1), and displaces the NR dye from the NR–DNA comple...
