1-type and biharmonic curves by using laplace operator in lorentzian 3-space arestudied and some theorems and characterizations are given for these curves.

This chapter assesses the nature and degree of environmental degradation and resource depletion in China and their relationship to economic activity and environmental policies. We describe regulatory and other policies and consider their political economy determinants. Inasmuch as this objective can only be partially achieved, we hope to contribute to a research agenda for environmental and res...

Effects of acute gamma-irradiation were investigated in the aquatic microcosm consisting of green algae (Chlorella sp. and Scenedesmus sp.) and a blue-green alga (Tolypothrix sp.) as producers; an oligochaete (Aeolosoma hemprichi), rotifers (Lecane sp. and Philodina sp.) and a ciliate protozoan (Cyclidium glaucoma) as consumers; and more than four species of bacteria as decomposers. At 100 Gy, ...

BACKGROUND DNA melting analysis for genotyping and mutation scanning of PCR products by use of high-resolution instruments with special "saturation" dyes has recently been reported. The comparative performance of other instruments and dyes has not been evaluated. METHODS A 110-bp fragment of the beta-globin gene including the sickle cell anemia locus (A17T) was amplified by PCR in the presenc...

The aim of this study was investigation of green marketing and its impacts on consumer behavior in sports shops in East Azerbaijan province of Iran. The present study is functionalized by objectives and done by field. The study statistical society was sports shops in East Azerbaijan and 210 samples were chosen randomly according to Morgan sampling method and 196 questionnaires were collected ...

a method has been presented for finding the solution surface of the npde: u  c , bounded by a general space curve. the method is based on the geometric characteristics of the surface, and is called the “cone-slot method”. it has been shown that such a surface can be obtained by movement of a cone inside the slot formed by the boundary space curve. an algorithm has been suggested on the basis ...

Sensitivity, stability, and specificity of the color-producing reaction of hydrogen peroxide with bezidine, leuco-malachite green, or o-dianisidine were tested in numerous systems containing hemoglobin and other hemoproteins. Use of urea or low temperature (to minus 12 degrees C), or both, was highly beneficial, especially with leuco-malachite green, for which the color reaction was stable, aft...

BACKGROUND We intend to design and validate a low-cost assay for the detection of hepatitis C virus (HCV) RNA using rapid-cycle RT-PCR. The procedure is performed in a closed system with little risk of contamination allowing PCR and product identification to be performed within one or two hours. METHODS A SYBR Green-based real-time RT-PCR for rapid detection of HCV. Amplicon synthesis was mon...

PURPOSE To test the validity of the color component subtraction method, a new objective technique of measuring nuclear cataract, and to correlate the tangent values of the different degrees of nuclear opacities to their corresponding subjective nuclear cataract grading using the Lens Opacities Classification System II and to another objective method of measuring nuclear cataract. METHODS Dens...

Green tea extract is a widely used dietary supplement. The objective of this study was to assess the influence of a decaffeinated green tea (DGT; Camellia sinensis) extract on the activity of the drug-metabolizing enzymes cytochrome P-450 2D6 and 3A4. Probe drugs dextromethorphan (30 mg, CYP2D6 activity) and alprazolam (ALPZ; 2 mg, CYP3A4 activity) were administered orally to healthy volunteers...
