Nandakumar K., A finite element technique for multifluid incompressible flow using Eulerian grids
No full textAbstract The paper presents a finite element method for 3D incompressible fluid flows with capillary free boundaries. It uses a fixed Eulerian grid of 10 nodes (P 2 À P 1 ) tetrahedra and tracks the free boundary using a six nodes (P 2 ) triangular surface grid. In order to improve the mass conservation properties of the method, a local enrichment of the finite element basis in the elements intersected by the free boundaries is employed. In addition to the surface tracking, it also advects a smooth indicator function for an easy identification of the fluid properties in the different parts of the domain. The advective part of the Navier-Stokes equations is split and integrated with a characteristic method. The remaining generalized Stokes problem is resolved by means of an inexact outer-inner (Uzawa) iteration with a properly chosen preconditioner. The performance of this technique is evaluated on several problems involving droplets in viscous liquids

FACTORS INFLUENCING LITTER TRAITS AND BODY WEIGHT UPTO 12 WEEKS AMONG TEMPERATE RABBIT BREEDS IN HUMID TROPICS
No full text[EN] High prolificacy and fast growth rate make rabbit an
ideal meat animal for the developing countries. Present investigation
was aimed at analysing the prolificacy and growth rate among
temperate breeds of rabbits namely, New Zealand White, Grey Giant
and Soviet Chinchilla, under humid tropics of Kerala, India. The
effects of breed and sire on litter traits and the effects of breed, sire
and sex on body weight traits were analysed. Data from 172
kindlings showed an average litter size at birth of 4.38 and litter
weight at birth of 228 g. Breed effects were significan! (P<0.05) on
litter size and litter weight at weaning. The highest litter size at weaning was obtained in Grey Giant (1 .96), followed by New
Zealand White (1.87) and the lowest in Soviet Chinchilla (1.18). The
litter weights al weaning were 1084, 1074 and 708 g for Grey Giant,
New Zealand White and Soviet Chinchilla, respectively. Pre-weaning
mortality was found to be modulated by breed to a significan! level (P
s 0.05) with New Zealand White having the lowest pre-weaning
mortality. Body weights al six weeks and twelve weeks averaged 612
g and 1168 g, respectively. Body weight at 12 weeks of age was
significantly (P<0.05) influenced by sire. The effects of breed and sex
on body weight traits was found to be non-significan!.[FR] Sa forte prolificité et sa grande vitesse de croissance fon! du lapin

Comparing the Bayesian Unknown Change-Point Model and Simulation Modeling Analysis to Analyze Single Case Experimental Designs
No full textData Availability Statement: The original contributions presented in the study are included in the article/supplementary material (https://github.com/prathiba-stat/BUCP), further inquiries can be directed to the corresponding author.Copyright © 2021 Natesan Batley, Nandakumar, Palka and Shrestha. Recently, there has been an increased interest in developing statistical methodologies for analyzing single case experimental design (SCED) data to supplement visual analysis. Some of these are simulation-driven such as Bayesian methods because Bayesian methods can compensate for small sample sizes, which is a main challenge of SCEDs. Two simulation-driven approaches: Bayesian unknown change-point model (BUCP) and simulation modeling analysis (SMA) were compared in the present study for four real datasets that exhibit “clear” immediacy, “unclear” immediacy, and delayed effects. Although SMA estimates can be used to answer some aspects of functional relationship between the independent and the outcome variables, they cannot address immediacy or provide an effect size estimate that considers autocorrelation as required by the What Works Clearinghouse (WWC) Standards. BUCP overcomes these drawbacks of SMA. In final analysis, it is recommended that both visual and statistical analyses be conducted for a thorough analysis of SCEDs
Comparison of Macintosh, McCoy, and Glidescope video laryngoscope for intubation in morbidly obese patients: Randomized controlled trial
No full textObjectives: The aim of the study was to compare time to intubation and glottic visualization between Macintosh, McCoy, and Glidescope video laryngoscope (GVL) in morbidly obese patients.
Methodology: Forty-five American Society of Anesthesiologists I–III morbidly obese patients were randomized into three groups of 15 each and time to intubation, Cormack–Lehane grading, and Intubation Difficulty Score (IDS) were compared.
Results: GVL took more time to intubate (TTI) compared to Macintosh and McCoy laryngoscope (P = 0.0001). Overall IDS were similar between the groups.
Conclusion: To conclude, GVL takes longer TTI with no added advantage in IDS and hemodynamic response to intubation in morbidly obese patients. McCoy is only as effective as Macintosh and hence Macintosh laryngoscope should be laryngoscope of choice due to its widespread availability and familiarity
