Adaptive phenotypic plasticity is a key component of the ability of organisms to cope with changing environmental conditions. Fish have been shown to exhibit a substantial level of phenotypic plasticity in response to abiotic and biotic factors. In the present study, we investigate the link between environmental sensitivity assessed globally (revealed by phenotypic variation in body weight) and...
The aim of this study was to investigate intra- and interspecimen repeatability of an experimental procedure, which determines elastic and viscoelastic properties of knee ligaments. The collateral ligaments from sheep were used and the repeatability was evaluated in terms of the coefficient of variation. The results indicated a good intraspecimen repeatability (the coefficient of variation gene...
abstractof two mcall programs introducing 100 vocabulary items through two im the researcher of the present study was intrigued to compare the effects age modalities (pictures and streaming video) with those of a conventional method (teacher instruction) in an efl context. she set out to investigate whether such multimedia environments could provide a more effective environment for vocabulary...
The sedimentation coefficients of three proteins, which appeared homogeneous in the ultracentrifuge, have been determined at different rotor velocities. Two of the proteins, ovalbumin and human gamma-globulin, showed sedimentation coefficients that were approx. 10% higher at rotor velocities below 20000rev./min. than at 56100rev./min. The third protein, haemocyanin of Jasus lalandii, could not ...
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
the effect of drought on the seed yield and some associated characteristics of common been under normal and drought stress conditions and determination of durable genotypes to drought were studied by planting 32 genotypes in two separate augmented designs in normal and stress conditions. these genotypes were evaluated in randomized complete block design with 3 replications in the field of facul...
To determine yield stability and to evaluate genotype interaction with environment interaction, 18 genotype of barley (Hordeum vulgare L.) and a control group were evaluated in a randomized complete block design with 4 replications in 3 successive years (1997-2000) at 10 research stations. Simple and combined analysis of variance revealed significant genetic differences between yield genotypes ...
