Source and sink activity measured after anthesis in six poplar rice cultivars. The experiment was laid in randomized block design with six cultivars MTU-1001, MTU1010, MTU-7029, BPT-2231, BPT-3291 and BPT-5204 replicated four times. After anthesis, top three leaves separately, top three internodes collectively, panicle axis and grain of main culm were sampled at seven day interval and analysed for biochemical parameters that serve remobilization of nutrients. During the initial and later halves of the sampling, there was a shift in higher amylase activity from third to flag leaves.

A correlated sampling technique has been implemented to estimate the impact of cross section modifications on the neutron transport and in Monte Carlo simulations in one single calculation. This implementation has been coupled to a Total Monte Carlo approach which consists in propagating nuclear data uncertainties with random cross section files.

Pest control practices in the vegetable crops have been heavily dominated by the routine use of broad-spectrum insecticides to control pests. Concerns have emerged about the adverse consequences of over use of pesticide. These consequences include short and longterm health hazards, contamination and environmental degradation. To minimize the pest losses farmers heavily depend on the chemical pesticides and accessing pest management information from the pesticide dealers due to weak state extension support system.

Numerous gel-free proteomics techniques have been reported over the past few years, introducing a move from proteins to peptides as bits of informa-tion in qualitative and quantitative proteome studies. Many shotgun pro-teomics techniques randomly sample thousands of peptides in a qualitative and quantitative manner but overlook the vast majority of protein modifi-cations that are often crucial for proper protein structure and function.

The blood glucose test is ordered to measure the amount of glucose in the blood right at the time of sample collection. It is used to detect both hyperglycemia and hypoglycemia, to help diagnose diabetes, and to monitor glucose levels in persons with diabetes. Blood glucose may be measured on a fasting basis (collected after an 8 to 10 hour fast), randomly (anytime), post prandial (after a meal), and/or as part of an oral glucose tolerance test (OGTT / GTT). To Prepare • Do not eat or drink anything, including water, after midnight before the test (6h). This includes...
