When a natural gas pipeline ruptures, the adjacent automatic line control valves (ALCVs) should close quickly to prevent leakage or explosion. The differential pressure set point (DPS) at each valve location is the main criteria for value setting in ALCV action. If the DPS is not properly adjusted, the ALCV may mistakenly close or it may not take any action at proper time. This study focused on...

AIM AND OBJECTIVE This pilot study was carried out to determine cardiovascular effects of a single session of an integrated "silver yoga" program in senior citizens of Serene Pelican Township, Pondicherry. MATERIALS AND METHODS Heart rate (HR) and blood pressure (BP) measurements were recorded in 124 senior citizens (75 female, 49 male) with mean age of 67.19 ± 10.61 year who attended an inte...

The three knobs of optical lithography, namely process factor k1, wavelength (λ) and numerical aperture (NA) have been constantly pushed to print smaller features. To get an equivalent k1 value below the fundamental limit of 0.25, double patterning (DP) has recently emerged as a viable solution for the 32nm lithography node. Various DP techniques exist such as litho-etch-litho-etch (LELE), lith...

The differentiation of CD4(+) CD8(+) double positive (DP) thymocytes requires the irreversible choice between two alternative lineages, distinguished by the mutually exclusive expression of either CD4 or CD8. Differentiating DP cells transiently down-regulate both CD4 and CD8, and this has complicated the debate whether the mechanism of CD4/CD8 lineage choice is instructive, stochastic/selectiv...

Given a set S of n points in R, the Closest Pair problem is to find a pair of distinct points in S at minimum distance. When d is constant, there are efficient algorithms that solve this problem, and fast approximate solutions for general d. However, obtaining an exact solution in very high dimensions seems to be much less understood. We consider the high-dimensional L∞ Closest Pair problem, wh...

Hairpin polyamides are synthetic ligands for sequence-specific recognition in the minor groove of double-helical DNA. A thermodynamic characterization of the DNA-binding properties exhibited by a six-ring hairpin polyamide, ImPyPy-gamma-PyPyPy-beta-Dp (where Im = imidazole, Py = pyrrole, gamma = gamma-aminobutyric acid, beta = beta-alanine, and Dp = dimethylaminopropylamide), reveals an approxi...

AIMS This study was performed to investigate the microbiological contamination of digestate product (DP) obtained from the anaerobic co-digestion of bovine manure and agricultural by-products. METHODS AND RESULTS Microbiological analyses were performed on bovine manure, fresh DP, liquid and solid fractions and stored liquid fraction of DP. A statistically significant reduction of faecal bacte...

drought preconditioning (dp) is a method of irrigation with low frequency and longer duration, to extend the root system and suppress drought damage in plants. in the present study, the effect of dp for 30 days on increasing tolerance to drought stress in two turfgrass species, creeping bentgrass (agrostis stolonifera cv.palustris) and tall fescue (festuca arundinacea cv. greystone) was investi...
