A study was undertaken on exploitation of indigenous Pseudomonas strains isolated from tea rhizosphere for disease control and productivity in tea. This included in vitro studies on plant growth promotion and biocontrol properties like production of phytohormones, siderophore, hydrogen cyanide, phosphate solubilization, and resistance to agrochemicals. The ability of Pseudomonas sp, was determi...

This study proposes an approach to develop a simple, time efficient and generic approach to assess and monitor tea plantations in Northeast India using time series remote sensing images. The tea industry in India is in a consolidation phase with the plantations suffering from yield decline and quality. Tea is affected by a plethora of factors including age, environment and management. Therefore...

The effects of iron-deficiency anaemia on workers productivity were studied in a tea plantation in Sri Lanka. The quantity of tea picked per day was studied before and after iron supplementation or placebo treatment. After one month's treatment significantly more tea was picked when the haemoglobin (Hb) concentration was increased by iron supplementation than when it was not. The degree of impr...

We are developing an Optical Readout Time Projection Chamber (O-TPC) detector for the study of the 1̧2ag reaction that determines the ratio of carbon to oxygen in helium burning. This ratio is crucial for understanding the final fate of a progenitor star and the nucleosynthesis of elements prior to a Type II supernova; an oxygen rich star is predicted to collapse to a black hole, and a carbon ri...

Ethylene polymerization by Cp2ZrCl2-B(C6F5)3-TEA catalyst system using low Al/Zr ratio has been studied with varying ethylene pressure, catalyst concentration, Al/Zr ratio, and reaction temperature. The study showed that there was an optimum condition for each variable at which maximum productivity was obtained. It was proposed that there were two competing reactions, the catalyst activation an...

This study was done to determine the effects of different thermal drying methods (sun drying, microwave drying and hot air oven drying) on the total phenolic content (TPC), total anthocyanin content and the antioxidant properties of Vitex negundo (VN) tea. Significant decline (P < 0.05) in antioxidant properties of hot air oven drying shows that this method is not the best method to preserve an...

iced tea is a world popular beverage,for example about 80% of people in italy and united states, consume iced tea as a thirsty-quenching beverage. however, it is also believed that iced tea contains health benefit components. process of iced tea involved tea solid extraction and then mixing with edible acids, flavors, sugar or non-nutritional sweeteners. in this research, regarding to the deman...

background: tannase can be obtained from the various sources for example tannin rich plants; however microbial sources are preferred for industrial production. in microbial sources, the aspergillus and penicillium genus and lactic acid bacteria mostly produce tannase. however, it has been identified that this enzyme is produced by many fungi and bacteria, but researches are continuing to find n...
