Two exponential wave integrator Fourier pseudospectral (EWI-FP) methods are presented and analyzed for the long-time dynamics of Dirac equation with small potentials characterized by ??(0,1] a dimensionless parameter. Based on (symmetric) temporal derivatives in phase space followed applying discretization spatial derivatives, EWI-FP explicit spectral accuracy second-order time any fixed ?=?0. ...

Engineered Water Injection (EWI) has been increasingly tested and applied to enhance fluid displacement in reservoirs. The modification of ionic concentration provides interactions with the pore wall, which facilitates oil mobility. This mechanism carbonates alters natural rock wettability being quite an attractive recovery method. Currently, numerical simulation this injection method remains l...

The study was conducted to determine the effect of varying protein levels and preservation method on internal egg qualities of Japanese quails. A total of 180 birds were randomly allotted into three dietary treatments in a completely randomized design (CRD) replicated six times. A factorial arrangement of 3x4x4 which involves 3 protein levels, 4 storage method and 4 time intervals was designed ...

The gonadsomatic index (GSI) of mottled skate was the highest in April, GSI and HSI showed a reverse phase for its reproductive cycle. The fish had one pair of egg capsules, having 1 to 7 fertilized eggs, and spawned all the year round. When surveying the reproductive characteristics of females over 63 ㎝ in disc width, we found the spawning peak was between April to June, and the appearance rat...

In this study, spermatheca and eggs of Pyrrhocoris apterus (Heteroptera: Pyrrhocoridae were examined by light microscope SEM. The have ~1.30 mm length 0.94 width. Newly laid turn from white to yellow as soon embryonic differentiation. P. egg surface shows polygonal (usually hexagonal pentagonal) shapes. pipe shaped 6-7 micropylar projections. egg-burster which is a dark T-shaped or triangular p...

The present study investigated the biology and morphometric analysis of rugose spiralling whitefly (RSW), Aleyrodicus rugioperculatus on coconut under mini net house condition at Department Agricultural Entomology, Tamil Nadu University-Coimbatore during 2019-2020. was studied by clip cage method morphometrics were done using Leica image analyser. Total lifecycle spiraling 56.23 ± 2.20 days. De...

In this experiment the effects of supplementation of the diet of laying hens with sodium selenite (SS) or selenized yeast (SY) on quality of eggs were studied. The chickens of Shaver Starcross hybrid were randomly divided at the day of hatching into 4 groups (n=12 in each group). The birds were fed from Day 1 of life till 9 months of age with diets differing in amounts and/or forms of selenium....
