Deregulation eliminates the boundary of the territory of the monopoly power industry. Competition forces utilities to improve power quality as well as to reduce investment and operation costs. Feeder imbalance describes a situation in which the voltages of a three-phase voltage source are not identical in magnitude, or the phase differences between them are not 120 electrical degrees, or both. ...

The mechanism of feeding slag-forming mixture (SFM) with a pneumatic drive has number disadvantages associated, in particular, the uneven supply into mould. To eliminate drawbacks, device an electric was designed to them. In order ensure control SFM process, automated system been developed that provides real-time information on technological process mould continuous casting machine, including s...

The inconsistency of efficiency in murine embryonic stem cell (ESC) production might be associated with the differences in preparation and cryopreservation of the feeder cell layer. As the cryopreservation of mouse embryonic fibroblast (MEF) declined the quality of MEF as feeder cell layer, an effective protocol should be determined to produce murine ESC on frozen-thawed feeder cell layer as ef...

Background Umbilical cord blood has been used for transplantation in regenerative medicine of hematological disorders. MicroRNAs are important regulators of gene expression that control both physiological and pathological processes such as development and cancer. Some studies have shown that miR-33, p53 and c-myc have critical roles in control of self-renewal cells. Objective To understand th...

Human hematopoietic stem cells (hHSCs) cannot be maintained in vitro for extended time periods because they rapidly differentiate or die. To extend in vitro culture time, researchers have made attempts to use human mesenchymal stem cells (hMSCs) to create feeder layers that mimic the stem cell niche. We have conducted an array of experiments including adipocytes in these feeder layers that inhi...

BACKGROUND Posterior fossa arteriovenous malformations (AVMs) are considered to have a higher risk of poor outcome, as are AVMs with associated aneurysms. We postulated that posterior fossa malformations may be more prone to associated feeder vessel aneurysms, and to aneurysmal source of hemorrhage. OBJECTIVE To examine the prevalence and hemorrhagic risk of posterior fossa AVM-associated fee...

Mouse embryonic fibroblasts (MEFs) and human foreskin fibroblasts (HFFs) are used for the culture of human embryonic stem cells (hESCs). MEFs and HFFs differed in their capacity to support the proliferation and pluripotency of hESCs and could affect cardiac differentiation potential of hESCs. The aim of this study was to evaluate the effect of MEFs and HFFs feeders on dopaminergic differentiati...

Rats exposed to a basic interfood clock (a sequence of four different 12-s lights) during a 48-s interfood interval (IFI) showed a characteristic distribution of behavior: responses near the feeder peaked after food presentations, locomotion away from the feeder peaked in the middle of the IFI, and nosing in the feeder peaked just before food. Rats (Group Shorter) receiving interfood stimuli th...

The efficiency of the public transport system in any city depends on integration of its major public transport modes. Suburban railway and public buses are the modes normally used by the majority of commuters in metropolitan cities of developed and developing countries. Integration of these two services reduces overall journey time of an individual. In this research, a model is developed for op...

screw-retained implant restorations have an advantage of predictable retention as well as retrievability, and obviate the risk of excessive sub-gingival cement commonly associated with cement retained implant restorations. screw-retained restorations generally have screw access holes, which can compromise esthetics and weaken the porcelain around the holes. the purpose of this study is to descr...
