Increasing material’s strength is of particular importance. Improving material’s mechanical properties such as strength could reduce the size and weight of the structure. The size and weight of the structure are among the effective parameters in design. Since the past a variety of methods have been developed to increase the strength of metals that are capable of increasing metals’ strength to a...

background and objectives: pcr is a sensitive assay and could be used as an accurate diagnostic method for detecting various types of microorganisms' genome in low concentration in biological specimens. the demand for sensitive, rapid, safe and easy detection of pcr products has led researchers to a combination of this method with elisa. materials and methods: conserved sequences were selected ...

The application of the [Pd{C6H3(CH2CH2NH2)-4-OMe-5-κ2-C,N}(μ-Br)]2 complex of 2-methoxyphenethylamine in the Heck coupling reaction was considered under both conventional and microwave irradiation conditions, and their results were compared. This complex is an efficient, stable and non-sensit...

1,3-dibromo-5,5-dimethylhydantoin (dbh), as a cheap and commercially available reagent, is efficiently able to catalyze the synthesis of polyhydroquinoline derivatives and 12-aryl-8,9,10,12-tetrahydro[a] xanthene-11-ones via one-pot multi-component reactions. this novel synthetic method has the advantages of low cost and availability of the catalyst, short reaction times, high to excellent yiel...

INTRODUCTION Osteoarthritis (OA), as one of the leading causes of disability, decreases the quality of life for those suffering from the disease and creates a substantial financial burden. Intra-articular hyaluronic acid (HA) can provide relief from the symptoms of OA and multiple HA products are prescribed. The purpose of this study is to examine the single payer cost-effectiveness of various ...

High bandwidth, uncooled, Indium Arsenide (InAs) electron avalanche photodiodes (e-APDs) with unique and highly desirable characteristics are reported. The e-APDs exhibit a 3dB bandwidth of 3.5 GHz which, unlike that of conventional APDs, is shown not to reduce with increasing avalanche gain. Hence these InAs e-APDs demonstrate a characteristic of theoretically ideal electron only APDs, the abs...

Milk and yogurt are important elements of the human diet, due to their high nutritional value and their appealing sensory properties. During milk processing (homogenization, pasteurization) and further yogurt manufacture (fermentation) physicochemical changes occur that affect the flavor and texture of these products while the development of standardized processes contributes to the development...
