Purpose – There has been growing interest in studying the internationalisation of small and medium-sized high-technology firms. This literature tends to equate “internationalisation” with the “internationalisation of sales”. Yet sales are not the only international activity of high-tech firms. High-tech firms need resources and not just markets. The purpose of this paper is to contribute to an understanding of this resource dimension of the international behaviour of high-tech firms. Design/methodology/approach – The empirical basis for the study lies in a multiple case study of six high-tech

To determine the effect of different harvesting time on antioxidant capacity in Jerusalem artichoke polysaccharides (inulin), the Jerusalem artichoke before and after overwintering were collected from the same region, and then evaluate their antioxidant capacity in vitro by reducing power assay, DPPH radical-scavenging assay and hydroxyl radical-scavenging assay. Ascorbic acid at similar mass concentration was served as positive control. The results showed no significant difference were observed in reducing power when the absorbance values were about 0.3.

Manual scavenging is an occupation which has been in existence since the human society. The inhuman practice of manually take out night soil which comprises removal of human waste from dry toilets with their bare hands, brooms, or metal scrappers; transporting excrements and bags to dumping sites for disposal is not only diabolic but perhaps the top degree of human rights violation. Manual scavenging is a sort of enforced labour in some places. It passes on from generation to generation. Culture of getting prevailing amongst them is also depriving them of their rights.

The present study was aimed at investigating the chemical profiles of the methanolic extract of leaves of Centella asiatica as well as to assess its antioxidative activity. In this study, a methanolic extract (50 g/L) was obtained by infusion followed by cold maceration for 24 h. The phytochemical screening of the plant extract demonstrated the presence of several classes of compounds like alkaloids, flavonoids, tannins and steroids. The concentration of the plant extract needed for 50% scavenging (IC50) of DPPH was found to be 40.4 μg/ml whereas IC50values for the positive control was found t

Today, there is an increasing interest in antioxidants, especially to prevent the known harmful effects of free radicals in human metabolism and their deterioration during processing and storage of fatty foods. In both cases, natural-source antioxidants are preferred over synthetic antioxidants. So, there has been a parallel increase in the use of assays to estimate antioxidant efficacy in human metabolism and food systems. Today, there are many bioanalytical methods that measure the antioxidant effect. Of these, the 1,1-diphenyl-2-picrylhydrazil (DPPH) removing assay is the most putative, pop

In this paper, the work was mainly studying influence of pH on Fenton reaction and gingerol scavenging hydroxyl radical. The antioxidant activity of gingerol was characterized by the scavenging hydroxyl ratio and scavenging hydroxyl ratio was analyzed by the spectrophotometry. Hydroxyl radical was produced by Fenton reaction. In the experiment pH and buffer solution have influence on the scavenging hydroxyl radical and Fenton reaction. Gingerol exhibits a strong scavenging radical activity for hydroxyl radical (OH.). The scavenging hydroxyl radical of different extractions of ginger oleoresin
