Pump sump design is very crucial in ensuring a minimum requirement for its operation. Improper pump will influence the development of vortices and swirls that can adversely affect efficiency which subsequently could damage pump. This be mitigated by installing an anti-vortex device (AVD) beneath intake pipe sump. The AVD works suppressing flow water into pipe. ANSI/HI 9.8-2012 standard has outl...

introduction: during early neural tube formation, the notochord is essential for the induction of ectoderm and for the subsequent differentiation of the neuroepithelium forming diverse cell types in the neural tube. due to the key role of the glycoconjugates in many developmental events, the early distribution of these molecules in early notochordal interaction with adjacent tissues were studie...

Three experiments investigated the effects of midazolam on acquisition of fear-mediated analgesic responses in rats conditioned on the heated floor of a hot-plate apparatus. Experiment 1 demonstrated that a moderate dose (1.25 mg/kg) of midazolam administered prior to conditioning impaired acquisition of conditioned analgesia in rats retested on the heated floor 24 h later. This effect of midaz...

We have developed an in vitro model of the isolated chicken neural plate. Here we demonstrate that even in the absence of notochord, the neural plate rapidly develops a typical dorsoventral patterning. This observation suggests that the ventral cell types are specified or at least predetermined prior to notochord formation and that permissive conditions are sufficient for differentiation of ven...

Megasplay faults, very long thrust faults that rise from the subduction plate boundary megathrust and intersect the sea floor at the landward edge of the accretionary prism, are thought to play a role in tsunami genesis. We imaged a megasplay thrust system along the Nankai Trough in three dimensions, which allowed us to map the splay fault geometry and its lateral continuity. The megasplay is c...

Hensen's node, also called the chordoneural hinge in the tail bud, is a group of cells that constitutes the organizer of the avian embryo and that expresses the gene HNF-3(&bgr;). During gastrulation and neurulation, it undergoes a rostral-to-caudal movement as the embryo elongates. Labeling of Hensen's node by the quail-chick chimera system has shown that, while moving caudally, Hensen's node ...

Sonic hedgehog (Shh) encodes a signal that is implicated in both short- and long-range interactions that pattern the vertebrate central nervous system (CNS), somite and limb. Studies in vitro indicate that Shh protein undergoes an internal cleavage to generate two secreted peptides. We have investigated the distribution of Shh peptides with respect to these patterning events using peptide-speci...

Aim: To assess the role of Magnetic resonance imaging (MRI) and pelvic organ prolapse quantification (POPQ) system in the evaluation of female pelvic organ prolapse. Design: Prospective study. Setting: Tanta University Hospital. Patients: The study was carried out on 60 patients having clinical manifestations suggesting pelvic floor weakness. Intervention: All the patients were subjected to his...

Proteins of the Netrin family have been implicated in axon guidance in both C. elegans and vertebrates. Here, we report the cloning and expression analysis of a zebrafish netrin homologue (net1). net1 is expressed in the floor plate and the anterior ventral neural tube. Its expression is ectopically induced by misexpression of sonic hedgehog (shh) and a dominant negative mutant of the regulator...
