    Forwarding large volume of live content to relevant users in scalable efficient way in emergency application is main challenging task. One of the model named as the publisher and subscribe is used to forward the event service to users. but it fails to provide relevant event match services to subscribers another major problem is server fail .To handle this problem adopting cloud computing which provides complex computing and reliable communication. In this project proposing distributed overlay SkipCloud  to organize servers giving efficient scalable and reliable event matching services to subscribers. To partition the similar subscriptions in same server for each event hybrid multi-dimensional space partition technique is used. Finally proposed techniques shows efficiency in high matching event service and reduces the event forwarding delay

    Insulin processing and action in adipocytes: evidence for generation of insulin-containing vesicles by leupeptin and monensin

    Get PDF
    AbstractIncubation of adipocytes with 125I-insulin plus leupeptin or monensin, but not chloroquine, resulted in the appearance of a novel peak of 125I-insulin (modal density about 1.20 gml) on density gradient centrifugation; the appearance of the peak depended on the presence of specific insulin receptors on the cell surface. The fractions comprising this peak contained vesicles, probably originating from the Golgi apparatus, and dit not appear to be contaminated with lysosomes, mitochondria or plasma membrane. Entrapment of insulin in these vesicles per se did not prevent the activation of glucose transport, acetyl-CoA carboxylase or pyruvate dehydrogenase by insulin

    Comparison of Horizontal, Vertical and Diagonal Smooth Pursuit Eye Movements in Normal Human Subjects

    AbstractWe compared horizontal and vertical smooth pursuit eye movements in five healthy human subjects. When maintenance of pursuit was tested using predictable waveforms (sinusoidal or triangular target motion), the gain of horizontal pursuit was greater, in all subjects, than that of vertical pursuit; this was also the case for the horizontal and vertical components of diagonal and circular tracking. When initiation of pursuit was tested, four subjects tended to show larger eye accelerations for vertical as opposed to horizontal pursuit; this trend became a consistent finding during diagonal tracking. These findings support the view that different mechanisms govern the onset of smooth pursuit, and its subsequent maintenance when the target moves in a predictable waveform. Since the properties of these two aspects of pursuit differ for horizontal and vertical movements, our findings also point to separate control of horizontal and vertical pursuit.

    New potent inhibitors of angiotensin converting enzyme

    Get PDF
    AbstractUsing an earlier model of the favoured orientation of binding functions of angiotensin converting enzyme (ACE) inhibitors, it has been possible to postulate a new, 7,6-bicyclic system, based on hexahydropyridazine, which might be expected to have high potency. Some members of this system which have been synthesised have been shown to be very active ACE inhibitors, in vitro and in vivo

    Degradation of nuclear proteins: studies on transplanted B82 cell karyoplast proteins

    AbstractKaryoplasts were prepared from B82 cells (thymidine kinase deficient mouse L cells) by cytochalasin B mediated enucleation. Morphological measurements show that the nucleus constitutes 89% of a karyoplast by volume. Homokaryons were obtained by Sendai virus mediated karyoplast-B82 cell fusion. Transplanted nuclei were not destroyed catastrophically but were maintained intracellularly for at least 140 h. Transplanted nuclear proteins were degraded with an average half-life of 84 ± 7 h by processes partially sensitive to inhibition by NH4Cl (50%) and leupeptin (30%). The data therefore suggest that some nuclear proteins are translocated to the cytoplasm for lysosomal degradation

    Visual–vestibular interaction in progressive supranuclear palsy

    AbstractWe measured the stability of gaze during horizontal head rotations at 1–3 Hz in four patients with progressive supranuclear palsy (PSP), while they viewed a stationary target. Median gain of compensatory eye movements was 0.94, similar to control subjects. During rotation in darkness, median gain of vestibulo-ocular reflex (VOR) was 0.88, similar to controls. Conversely, the median gain of smooth-pursuit eye movements at 1.0 Hz was 0.23, lower than controls. A simple superposition model of smooth pursuit and the VOR could not account for the observed gaze stability during fixation. Our results are further evidence that a visually mediated mechanism, independent of smooth pursuit, optimizes eye movements to compensate for head rotations

    Ubiquitin—protein conjugates and αB crystallin are selectively present in cells undergoing major cytomorphological reorganisation in early chicken embryos

    AbstractUbiquitin—protein conjugates and αB crystallin are detected immunohistochemically in cells undergoing extensive morphological reorganisation in early chicken embryos. Cytoplasmic ubiquitinated proteins and αB crystallin are coordinately found in cells of the lens, notochord and myotome. The antigens appear in the myotome cells precisely, at the point at which the cells begin to migrate from the dorsomedial lip of the dermamyotome. The findings indicate that ubiquitin and αB crystallin may have a coordinate role in the extensive architectural remodeling which occurs in these developing tissues in the early chick embryo, Some form of functional association between protein ubiquitination and αB crystallin in cells may explain why αB crystallin is found with ubiquitin—protein deposits in some neurodegenerative diseases

    Examining the sustainability issues in UKOER projects: Developing a sustainable OER ecosystem in HE

    Get PDF
    The development of open educational resources (OERs) is becoming a strategic priority for governments and education institutions around the world, in response to funding cuts and rising costs in educational provision. In the United Kingdom, a government-sponsored Pilot Programme on Open Educational Recourses (JISC/HEA, 2009) was launched in 2009 with an initial budget of ÂŁ5.7m. This paper reviews the key sustainability issues identified by the projects including the different approaches and models that have been adopted in order to sustain the continuing development and release of OER once funding has ended. The analysis also considers the challenges relating to the development and implementation of policies and processes for sustainable OER practice within institutions and among academics. The paper concludes by drawing on the experiences from the wider United Kingdom and international OER communities to develop a sustainable OER ecosystem model that can facilitate discussions on future development of OER initiatives
