A solid phase extraction procedure for simultaneous separation and preconcentration of traceamounts of Cu+2 ion from various real samples prior to its determination by flame atomicabsorption spectrometry has been developed. The proposed method is based on the utilization ofmultiwalled carbon nanotube in combination with Cupferron ligand as a solid phaseextractant. The influences of the analytic...

in recent years, due to absence of integrated watershed management in most regions, natural resources have witnessed numerous damages with severe floods as one of its consequences which further leads to economic, social and environmental damages. presently, there is no optimal utilization of land in most watersheds hence no optimal model matching with facilities and objectives is used in the wa...

CONTEXT Retrospective drug utilization review is required of all state Medicaid programs and is performed by most private-sector prescription programs. However, it has not been shown to improve clinical outcomes or reduce the rate of potential prescribing errors, known as "exceptions." OBJECTIVE To look for an effect of retrospective drug utilization review on the rate of exceptions and of cl...

the genetic variation and diversity among fifty-eight polyvoltine silkworm genotypes was estimated by using ten economic traits. the results revealed that the single shell weight showed higher genetic variation such as pcv% (17.20%), gcv% (12.93%), and heritability (56.5%) followed by single cocoon weight, shell ratio and matured larval weight. the d2 (mahalonobis? distance) statistics revealed...

Aiming at the utilization of coal gasification slag, it is proposed to prepare slag as mine filling material. The optimum ratio cement: slag: gangue 1:5:1, mass fraction 70%, and dosage quicklime 4%. strength backfill reaches 4.23mpa, which can meet requirements strength.

–The maintenance of pavements and particularly for flexible pavement is an essential requirement for the efficiency of highway network. For better serviceability, flexible pavements require more maintenance as compared to maintenance required for rigid pavements. But developing counties like India does not have sufficient budget or funds to satisfy the requirements. The maintenance & rehabilita...

Renewable energy has had a steady and continuous growth in electric sector worldwide. The need of the hour is to sensitize the general public about the importance of judicious use of energy being generated by conventional sources energy sources and simultaneously shift our dependence on renewable but sustainable energy sources. To mitigate environmental degradation and reduce carbon emission wo...
