This paper contains a strain gradient theory to capture size effects in rotating nanodisks of variable thickness under thermal and mechanical loading. Material properties of nanodisks have been taken homogeneous material. The strain gradient theory and the Hamilton’s principle are employed to derive the governing equations. Due to complexity of the governing differential equation and boundary c...

Background: Despite advances in obstetrics and gynaecology, the perinatal mortality among twins still remains high. This study compares the perinatal outcome of first and second twin. Materials & Methods: A prospective study was conducted at Institute of maternal and Child Health, Calicut over a period of one year; 2005 to 2006. 200 (antenatal women with) twin pregnancies were followed up from ...

In the framework of H2020 Cleansky2 project ROSSINI an industrial centrifugal compressor stage including vaneless diffuser and a non-symmetric volute is investigated with regard to development flow instabilities rotating stall.Due complex path geometry sophisticated instrumentation concept was developed allowing for combined high resolution field unsteady pressure investigation. This paper aime...

This study examines the value of assessing inter-twin membrane folding in monochorionic twin pregnancies in the prediction of twin-to-twin transfusion syndrome. In 83 monochorionic twin pregnancies ultrasound scans were carried out at 10-14, 15-17 and 19-21 weeks to investigate folding of the inter-twin membrane as an early sonographic feature of inter-twin discrepancy in amniotic fluid volume....

In this research, a rotating solar still that uses external bottom reflectors was experimentally investigated. The solar still and reflectors have the capability to shift their angle with respect to the south and the reflectors have the capability to shift their angle with respect to the horizon. The experiment has been performed in both fixed and rotating states. For the fixed state the solar ...

the solutions of mathematical models for the estimation of the kinetic, and biokinetic parameters of naphthalene, anthracene and pyrene during degradation in surface and subsurface soils are presented in this work. the models were developed using the twin concepts of rate-determining step and steady-state approximation method. they described the biodegradation of single and a mixture of polycy...

background: the lori-bakhtiari sheep breed is one of the most common native breed in the south-western parts of iran. the peri-parturition period (2 weeks before to, 2 weeks after parturition), is generally of critical importance regarding the health, production and profitability of the ewes. objectives: this study was carried out to compare the serum concentrations of glucose, non-esterified f...

Background: Monochorionic twin gestations are at increased risk of a variety of pregnancy complications which can be minimized by early antepartum diagnosis and management. This study is to assess the influence of chorionicity in twin pregnancies on perinatal outcome. Materials and Methods: A prospective study was conducted at, Institute of maternal and child health Calicut over a period of one...
