Effect of downhill sprint training on speed of school boys

The aim of this study was to examine the downhill sprint training on the speed of school boys. Thirty healthy school boys were selected to experimental (n = 15) and control (n = 15) groups. They carried out 8 weeks downhill training. Speed was measured before and immediately after a training period. The data collected from the two groups prior to and post experimentation were statistically analyzed by analysis of covariance (ANCOVA). The result of the study found that due to the eight weeks of downhill training the speed of the subjects was increased

Perforated Right Side Colonic Diverticulum with Abscess

Colonic perforation is a rare cause of intraabdominal abscess. It presents, more frequently in frail elderly patients, with heterogeneous signs and symptoms which hamper the clinical diagnosis. Subcutaneous emphysema with pneumomediastinum and  muscle abscess are unusual signs. Colonic  perforation may be consequent to diverticulitis or locally advanced colon cancer. Due to the anatomy of the abdominal space and different physiopathology, diverticular perforation may present with air and pus collection; on the other hand perforated colon cancer may cause groin mass and psoas abscess

CONSEQUENCES OF WEIGHTED VEST AND WEIGHTED SLED RUNNING ON ELASTIC POWER OF SCHOOL SPRINTERS

The purpose of the study was to cause of weighted vest and weighted sled running on elastic power of school sprinters. To achieve the purpose of this study, forty five male sprinters from the Public school. The age, height and weight of the subjects ranged from 17 to 19 years, 155 to 165 centimetres and 50 to 55 kilograms in that order. They were divided into three groups; each group consisted of fifteen subjects. Group-I underwent weighted vest sprint training, group-II underwent weight sled training and group-III acted as control who does not participate in any training programme. The data collected from the three groups prior to and post experimentation were statistically analyzed by analysis of covariance (ANCOVA). When the obtained ‘F’ ratio value in the analysis of covariance test was significant, the Scheffe’s test was applied as post hoc test to determine the paired mean differences, if any. In all the cases, statistical significance was fixed at .05 levels. Conclusion: The experimental group sprinters had significant improvement on elastic power when comparing to the control group sprinters.  Article visualizations

MEASURE THE USAGE OF E-RESOURCES: SCIENTOMETRIC MODEL

It is essential to evaluate the use of every resource that is acquired by the institute or through consortia. Therefore the objective of the study is to find trends in the usage of e-resources. The study emerged with three formulas such as Ratio of Resources, Ratio of Utilization and Resource Impact Factor. The study derived three axioms such as axiom 1 that Total number of downloads was directly proportional to the number of resources; Axiom 2 : Total number of downloads was directly proportional to the number of users and Axiom 3: Uses of e-resources were directly proportional to the number of resources and number of users. To prove the axioms, the data available regarding of usage of e-resources through e-ShodhShiindu (eSS) Consortium at the https://infistat.inflibnet.ac.in/ has been taken for analysis. The usage trends of nine full-text journals of the Gandhigram Rural Institute – Deemed to be University were taken up from 2012 to 2019. Use of e-resources was directly proportional to the number of resources and the number of users and not by the number of downloads. This paper emphasizes different parameters in measuring the use of e-resources subscribed based on the number of downloads

Effect of compatibilizers on lignin/bio-polyamide blend carbon precursor filament properties and their potential for thermostabilisation and carbonisation

Biobased blends from hydroxypropyl modified lignin (TcC) and a biobased polyamide (PA1010) were produced by continuous sub-pilot scale melt spinning process. A reactive compatibilization was employed with the help of two different compatibilizers (ethylene-acrylic ester-maleic anhydride (MA) and ethylene-methyl acrylate-glycidyl methacrylate (GMA)) to enhance the compatibility between the TcC and PA1010. The enhanced compatibility between the TcC and PA1010 achieved by reaction between hydroxyl groups with maleic anhydride groups in the MA compatibilizer or epoxy groups in the GMA compatibilizer via nucleophilic substitution, was confirmed by chemical (Fourier infrared measurements), physical (glass transition, melting and crystallization behaviour), rheological, morphological and tensile properties of the filaments from compatibilized blends. MA compatibilizer required a higher concentration (2 phr) than GMA (1 phr) to achieve an optimal performance because of the difference in the reactive group's concentration within the each compatibilizer. The MA compatibilizer though was more effective than GMA. The precursor blended filaments were successfully carbonized in a lab scale experiment to yield coherent carbon fibres with tensile stress values of 192 ± 77 and 159 ± 95 MPa; and moduli of 16.2 and 13.9 GPa respectively for uncompatibilised and 2% MA compatibilized blends. That the compatibilized carbon fibre properties are slightly inferior may be attributed to the need to accurately control and optimise applied stress during the thermostabilisation and carbonization stages. Notwithstanding, these differences, the results indicate the potential benefit of using compatibilized TcC/PA1010 blend filaments as carbon fibre precursors

Omega-3 Fatty Acid-Derived Resolvin D2 Regulates Human Placental Vascular Smooth Muscle and Extravillous Trophoblast Activities

Omega-3 fatty acids are important to pregnancy and neonatal development and health. One mechanism by which omega-3 fatty acids exert their protective effects is through serving as substrates for the generation of specialized pro-resolving lipid mediators (SPM) that potently limit and resolve inflammatory processes. We recently identified that SPM levels are increased in maternal blood at delivery as compared to umbilical cord blood, suggesting the placenta as a potential site of action for maternal SPM. To explore this hypothesis, we obtained human placental samples and stained for the SPM resolvin D2 (RvD2) receptor GPR18 via immunohistochemistry. In so doing, we identified GPR18 expression in placental vascular smooth muscle and extravillous trophoblasts of the placental tissues. Using in vitro culturing, we confirmed expression of GPR18 in these cell types and further identified that stimulation with RvD2 led to significantly altered responsiveness (cytoskeletal changes and pro-inflammatory cytokine production) to lipopolysaccharide inflammatory stimulation in human umbilical artery smooth muscle cells and placental trophoblasts. Taken together, these findings establish a role for SPM actions in human placental tissue

In Situ Compatibilization of Biopolymer Ternary Blends by Reactive Extrusion with Low-Functionality Epoxy-Based Styrene Acrylic Oligomer

[EN] The present study reports on the use of low-functionality epoxy-based styrene¿acrylic oligomer (ESAO) to compatibilize immiscible ternary blends made of poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBV), polylactide (PLA), and poly(butylene adipate-co-terephthalate) (PBAT). The addition during melt processing of low-functionality ESAO at two parts per hundred resin (phr) of biopolymer successfully changed the soften inclusion phase in the blend system to a thinner morphology, yielding biopolymer ternary blends with higher mechanical ductility and also improved oxygen barrier performance. The compatibilization achieved was ascribed to the in situ formation of a newly block terpolymer, i.e. PHBVb- PLA-b-PBAT, which was produced at the blend interface by the reaction of the multiple epoxy groups present in ESAO with the functional terminal groups of the biopolymers. This chemical reaction was mainly linear due to the inherently low functionality of ESAO and the more favorable reactivity of the epoxy groups with the carboxyl groups of the biopolymers, which avoided the formation of highly branched and/or cross-linked structures and thus facilitated the films processability. Therefore, the reactive blending of biopolymers at different mixing ratios with low-functionality ESAO represents a straightforward methodology to prepare sustainable plastics at industrial scale with different physical properties that can be of interest in, for instance, food packaging applications.This research was funded by the EU H2020 project YPACK (Reference number 773872) and by the Spanish Ministry of Science, Innovation, and Universities (MICIU) with project numbers MAT2017-84909-C2-2-R and AGL2015-63855-C2-1-R.
