The objective of the present paper is to study Kenmotsu manifold admitting Schouten-van Kampen connection. We study Kenmotsu manifold admitting Schouten-van Kampen connection satisifying certain curvature conditions. Also we prove equivalent conditions for Ricci soliton in a Kenmotsu manifold is steady with respect to the Schouten-van Kampen connection

Study of prevalence of non alcoholic fatty liver disease in type 2 diabetes mellitus patients and variations in liver function tests, lipid profile and mean platelet volume in patients with fatty liver in comparison with patients without fatty liver

Background: Type 2 diabetes mellitus (T2DM) patients potentially are at risk of developing non-alcoholic fatty liver disease. The aim of the study is to determine the prevalence of NAFLD among T2DM patients, diagnosed by ultrasonography of liver, to study the age & sex incidence of NAFLD and to compare the liver function tests, lipid profile and mean platelet volume (MPV) between individuals with NAFLD and without NAFLD.Methods: Total of 97 type 2 diabetes mellitus ambulatory patients were selected for the study. Among them 62 were males (63.9%) and 35 were females (36%). 78 healthy subjects were selected as controls. Their age ranged between 27 to 75 years. Serum was used for the estimation of FBS, PPBS, total bilirubin, direct bilirubin, AST, ALT, ALP, GGT, total protein, albumin, total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C). EDTA blood was used for the estimation of MPV. Fatty liver was diagnosed on ultrasound based on the echogenicity and size of the liver.Results: In this study, liver size & echotexture, liver enzymes such as AST, ALT, ALP and GGT, serum cholesterol, TGL and LDLC were found to be statistically significantly increased in T2DM patients when compared to controls. T2DM patients were divided in to two groups; group 1 included patients with NAFLD and group 2 included patients without NAFLD. Liver size, AST, ALT, ALP, GGT, Cholesterol and TGL were significantly increased in group 1 patients when compared to group 2 patients (P value<0.05). Elevation of MPV was found to be more in group 1 patients than group 2 patients ranging between 12.1±3.0 and 10.2±0.9 respectively.Conclusions: Early detection and optimum control of diabetes mellitus is important to minimize the effect of diabetes on liver. Hence, assay of serum levels of hepatic enzymes and USG abdomen to detect NAFLD should be done in all patients with T2DM as preliminary diagnostic tests.

Cut-Through Switching Options in a MobilityFirst Network with OpenFlow

Mobile devices are expected to become the Internet’s predominant technology. Current protocols such as TCP/IP were not originally designed with mobility as a key consideration, and therefore underperform under challenging mobile and wireless conditions. MobilityFirst, a clean slate architecture proposal, embraces several key concepts centered around secure identifiers that inherently support mobility and trustworthiness as key requirements of the network architecture. This includes a hop-by- hop segmented data transport that allows late and dynamic rebinding of endpoint addresses to support mobility. While this provides critical gains in wireless segments, some overheads are incurred even in stable segments such as in the core. Bypassing layer 3 decisions in these cases, with lower layer cut through forwarding, can improve said gains. In this work, we introduce a general bypass capability within the MobilityFirst architecture that could provide both better performance and enable both individual and aggregate flow-level traffic control. Furthermore, we present a detailed OpenFlow-based design to bypass layer 3 routing in MobilityFirst, using layer 2 VLAN tagging. Finally, we present a prototype that shows that it is possible to use OpenFlow to create the bypass
