We have studied the single-neutron stripping reaction induced by ^23O on carbon target at beam energy of 72 MeV//A with a motive to analyze its ground state structure. The partial stripping cross sections as well as longitudinal momentum distribution of ^22O core have been calculated within the framework of the eikonal approximation approach. Several core-neutron spin coupling configurations, corresponding to J^π= 1/2 ＋ as ground state spin parity of ^23O, along with their suitable admixtures have been considered. The major outcome of the present work is that the s and d admixed configuration with a large contribution of s state seems to explain the longitudinal momentum distribution data more satisfactorily.

For the purpose of improving the strength of this dissimilarjoint, the present study was carried out to investigate the improvement in intermetallic layer by using a third material foil between the laying edges of the friction stir welded and hybrid welded AI6061-T6/AZ31 alloy plates. The difference in microstructural and mechanical characteristics of friction stir welded and hybrid welded AI6061-TO/AZ31 joint was compared. Hybrid butt- welding of aluminum alloy plate to a magnesium alloy plate was successfully achieved with Ni foil as filler material, while defect-free laser-friction stir welding （FSW） hybrid welding was achieved by using a laser power of 2 kW. Transverse tensile strength of the joint reached about 66% of the Mg base metal tensile strength in the case of hybrid welding with Ni foil and showed higher value than that of the friction stir welded joint with and without the third material foil. This may be due to the presence of less brittle Ni-based intermetallic phases instead of Al12Mg17.

The Coanda effect has long been employed in the aerospace applications to improve the performances of various devices. This effect is the ability of a flow to follow a curved contour without separation and has well been utilized in ejectors where a high speed jet of fluid emerges from a nozzle in the ejector body, follows a curved surface and drags the secondary flow into the ejector. In Coanda ejectors, the secondary flow is dragged in the ejector due to the primary flow momentum. The transfer of momentum from the primary flow to the secondary flow takes place through turbulent mixing and viscous effects. The secondary flow is then dragged by turbulent shear force of the ejector while being mixed with the primary flow by the persistence of a large turbulent intensity throughout the ejector. The performance of a Coanda ejector is studied mainly based on how well it drags the secondary flow and the amount of mixing between the two flows at the ejector exit. The aim of the present study is to investigate the influence of various geometric parameters and pressure ratios on the Coanda ejector performance. The effect of various factors, such as, the pressure ratio, primary nozzle and ejector configurations on the system performance has been evaluated based on a performance parameter defined elsewhere. The performance of the Coanda ejector strongly depends on the primary nozzle configuration and the pressure ratio. The mixing layer growth plays a major role in optimizing the performance of the Coanda ejector as it decides the ratio of secondary mass flow rate to primary mass flow rate and the mixing length.

The serum and glucocorticoid inducible protein kinase(SGK) family members share similar structure, substrate specificity and function with AKT and signal downstream of the phosphatidylinositol 3-kinase(PI3K) signalling pathway. They regulate a range of fundamental cellular processes such as cell proliferation and survival, thereby playing an important role in cancer development. This perspective intends to give an overview on the involvement of SGKs(particularly SGK3) in cancer progression, and compares the actions of SGK3 and AKT in cell cycle regulation, oncogenic signalling, and the potential as a therapeutic target for cancer.

We present results of the Mt Abu JHK photometric and HI Brackett γ line monitoring of the eruptive young stellar object V1647 Orionis （McNeil＇s Object） during its ongoing outburst phase in 2008-2012. We discuss JHK color patterns and extinction during the outburst and compare them with those from the previous out- burst phase in 2004-2005 and in the intervening quiescent period that lasted about 2 yr. Commencing from early 2012, the object has shown a slow fading out in all the bands. We report brightness variations in the nearby Herbig-Haro object HH22 that are possibly associated with those in V1647 Ori. We also present modeling of the spec- tral energy distributions of V 1647 Ori during both its recent outburst and its quiescent phase. The physical parameters of the protostar and its circumstellar environment ob- tained from the modeling indicate marked differences between the two phases.

Background:This study evaluated the effects of supplemental xylanase and xylooligosaccharides(XOS)in a cornsoybean meal(SBM)-based diet on growth performance and intestinal health of broilers.A total of 288 day-old chicks(Cobb 500)were allocated to 36 floor pens(8 birds/pen)equally in 9 dietary treatments in a 3×3 factorial *** treatments were combinations of 3 levels of xylanase(0,0.005% and 0.01% Econase XT)and 3 levels of prebiotics(0,0.005% and 0.01% XOS)added to basal mash diets formulated in three phases(starter,d 0-14;grower,d 15-28;finisher,d 29-42).The feed intake and body weights were recorded *** d 42,ileal sections were collected for histomorphometric and gene expression analysis,and cecal content was collected for determining short-chain fatty acids(SCFA)and ***:Xylanase linearly(P0.05).Supplemental xylanase and XOS did not affect average daily feed intake and feed conversion ratio(P>0.05).Xylanase and XOS did not change villus height(VH)or crypt depth(CD)ratio(P>0.05).However,xylanase exhibited a trend(P=0.097)on VH:CD *** inclusion of 0.01%XOS without xylanase increased the level of IL-10(a marker of anti-inflammatory cytokine)and IL-4(a T-cell differentiation cytokine)genes compared with control(P0.05).However,the mean proportion of family Ruminococcaceae was increased by the supplemental 0.01% xylanase(P<0.01).Conclusion:It can be concluded that XOS can enhance cecal fermentation,while xylanase can increase the body weight gain along with the ferment
