intra-specific variations in apex development of two salt-tolerant cultivars (cross rowshan 11 (cr) and kharchia-65) and one salt-sensitive cultivar (ghods) of spring wheat (triticum aestivum l.) grown in sand culture at selected levels of salinity (0, 100, 200, and 300 mol m-3 nacl and cacl2 in 5:1 molar ratio) were studied. to determine the apex lengths and the number of spikelet primordi...
In this study an extensive experimental research is carried out to develop a better understanding of the effects of Piano Key (PK) weir geometry on weir flow threshold submergence. Experiments were conducted in a 12 m long, 0.4 m wide and 0.7 m deep rectangular glass wall flume. The main objectives were to investigate the effect of the PK weir geometries including the weir length, weir height, ...
DNA repair is required to maintain genome stability in stem cells and early embryos. At critical junctures, oxidative damage to DNA requires the base excision repair (BER) pathway. Since early zebrafish embryos lack the major polymerase in BER, DNA polymerase ß, repair proceeds via replicative polymerases, even though there is ample polb mRNA. Here, we report that Polb protein fails to appear a...
The recently released persistent memory (PM) offers high performance, persistence, and is cheaper than DRAM. This opens up new possibilities for indexes that operate persist data directly on the bus. Recent learned exploit distribution have shown great potential some workloads. However, none support persistence or instant recovery, existing PM-based typically evolve B+-trees without considering...
Prior to root canal treatment at least one undistorted radiograph is required to assess canal morphology. The apical extent of instrumentation and the final root filling have a role in treatment success, and are primarily determined radiographically. Electronic apex locators reduce the number of radiographs required and assist where radiographic methods create difficulty. They may also indicate...
Recent efforts toward HIV vaccine development include the design of immunogens that can engage B cell receptors with the potential to affinity mature into broadly neutralizing antibodies (bnAbs). V2-apex bnAbs, which bind a protein-glycan region on HIV envelope glycoprotein (Env) trimer, are among the most broad and potent described. We show here that a rare "glycan hole" at the V2 apex is enri...
