Homogeneity in azinphosmethyl resistance was assessed in males of a laboratory-selected (Select-H) and susceptible (Yolo) colony of Trioxys pallidus (Hymenoptera: Aphidiidae) using a time response assay. No evidence of heterogeneity within the two colonies was found. Reciprocal crosses between the Yolo and Select-19 colonies resulted in F1 females which exhibited a semidominant response to azin...

In many countries, water pollution from industrial wastewater is a serious problem. This type of can have harmful impact on the environment, to reduce effects these pollutants, several physico-chemical methods are implemented, in particular adsorption bioadsorbents, it common process remove traces pollutants water, aim our work realize comparative experimental study isotherms and kinetics methy...

T he United States cannot conduct an eff ective counterterrorism campaign against al Qa’ida or other terrorist groups without understanding how such groups end. While it is clear that U.S. policymakers will need to turn to a range of policy instruments to conduct such campaigns—including careful police and intelligence work, military force, political negotiations, and economic sanctions—what is...

RFLP markers were used to investigate genetic diversity among California walnut (Juglans regia) cultivars and germplasm collected worldwide. Sixteen of 21 RFLP markers were polymorphic in the 48 walnut accessions tested. RFLP markers were useful for identifying walnut cultivars. All genotypes were heterozygous at ≈20% of the loci for both California and worldwide germplasm. California walnut ge...

The accuracy of regression model may have some warp when the observation data set exists outlier. We study to lessen the outlier effect in predicting GDP growth on the basis of fuzzy linear regression model in this paper. The result is eff ectively verified the performance of the model.

Control While many intervention techniques have been developed and applied with varying degrees of success, it remains clear that a comprehensive method for tick control still needs to be realised, especially for resource­constrained farmers. Conventional methods involve the use of commercial acaricides under intense dipping program­ mes. In Zimbabwe, the Department of Veterinary Services (DVS)...

Recognition that social, economic, political, and environmental factors directly aff ect HIV risk and vulnerability has stimulated interest in structural approaches to HIV prevention. Progress in the use of structural approaches has been limited for several reasons: absence of a clear defi nition; lack of operational guidance; and limited data on the eff ectiveness of structural approaches to t...

Polyvinyl ester green composites were synthesized with walnut shell powder (WSP) by in-situ polymerization technique. The green composites have been evaluated for mechanical properties such as tensile strength, tensile modulus and hardness. Sliding wear loss, specific wear rate and coefficient of friction were investigated by using computerized pin-on–disc machine at normal applied loads of 20,...
