Single-Phase Operation of Three-Phase Motors

Against the current backdrop of deteriorating economic and financial conditions, the authors consider recent trends and current prospects for credit unions in Great Britain. Although credit unions have experienced solid membership and asset growth, there are clouds on the horizon. Bad debts and loan arrears are on the rise and may be linked to recent legislative amendments and the increasing use by government of credit unions as a mechanism to achieve its financial inclusion goals. Whatever the reason, the deterioration in the loan book needs to be quickly addressed, or it will ultimately result in either more government bailouts or a stream of failing credit unions

The Relation between Solar Eruption Topologies and Observed Flare Features I: Flare Ribbons

In this paper we present a topological magnetic field investigation of seven two-ribbon flares in sigmoidal active regions observed with Hinode, STEREO, and SDO. We first derive the 3D coronal magnetic field structure of all regions using marginally unstable 3D coronal magnetic field models created with the flux rope insertion method. The unstable models have been shown to be a good model of the flaring magnetic field configurations. Regions are selected based on their pre-flare configurations along with the appearance and observational coverage of flare ribbons, and the model is constrained using pre-flare features observed in extreme ultraviolet and X-ray passbands. We perform a topology analysis of the models by computing the squashing factor, Q, in order to determine the locations of prominent quasi-separatrix layers (QSLs). QSLs from these maps are compared to flare ribbons at their full extents. We show that in all cases the straight segments of the two J-shaped ribbons are matched very well by the flux-rope-related QSLs, and the matches to the hooked segments are less consistent but still good for most cases. In addition, we show that these QSLs overlay ridges in the electric current density maps. This study is the largest sample of regions with QSLs derived from 3D coronal magnetic field models, and it shows that the magnetofrictional modeling technique that we employ gives a very good representation of flaring regions, with the power to predict flare ribbon locations in the event of a flare following the time of the model

ADP release is the rate-limiting step of the MT activated ATPase of non-claret disjunctional and kinesin

AbstractThe motor protein non-claret disjunctional (ncd) moves towards the minus ends of microtubules (MTs), whereas its close relative kinesin moves in the opposite direction towards the plus ends of MTs. The mechanisms of movement and directional reversal for these motor proteins are unknown. Here we report the rate constants for MT activated ADP release from a recombinant double-headed ncd protein, GST-MC5, and a recombinant double-headed kinesin protein, KΔ401, measured using the fluorescent nucleotide analogues methylanthranilyol ATP (mantATP) and mantADP. Comparison of the maximal MT activated mantADP release rates for these proteins with their maximal MT activated mantATP turnover rates indicates that ADP release is the rate-limiting step for ATP turnover for both ncd and kinesin. This data supports the view that directional reversal may result from structural rather than chemical kinetic differences in the way the motors interact with MTs

Positive interplay between FFAR4/GPR120, DPP-IV inhibition and GLP-1 in beta cell proliferation and glucose homeostasis in obese high fat fed mice

G-protein coupled receptor-120 (GPR120; FFAR4) is a free fatty acid receptor, widely researched for its glucoregulatory and insulin release activities. This study aimed to investigate the metabolic advantage of FFAR4/GPR120activation using combination therapy. C57BL/6 mice, fed a High Fat Diet (HFD) for 120 days to induce obesity-diabetes, were subsequently treated with a single daily oral dose of FFAR4/GPR120 agonist Compound A (CpdA) (0.1μmol/kg) alone or in combination with sitagliptin (50mg/kg) for 21 days. After 21-days, glucose homeostasis, islet morphology, plasma hormones and lipids, tissue genes (qPCR) and protein expression (immunocytochemistry) were assessed. Oral administration of CpdA improved glucose tolerance (34%
