In this paper, the dynamics of the relative motion problem in a perturbed orbital environment are exploited based on Gauss’ variational equations. The relative coordinate frame (Hill frame) is studied to describe the relative motion. A linear high fidelity model is developed to describe the relative motion. This model takes into account primary g

An investigation of the population parameters of Indian mackerel, Rastrelliger kanagurta (Cuvier, 1816) in the Marudu Bay, Sabah, Malaysia was carried out from January to September 2013. The relationship between total length and body weight was estimated as W=0.006TL3.215 or Log W=3.215LogTL – 2.22 (R2=0.946). Monthly length frequency data of R.

Carotenoids have shown extensive applications in pharmaceutical, aquaculture and animal feed industries. Recently, researchers have been studied on their potentiality for the health benefits in reducing the risk of cancer and neurodegenerative diseases. Based on above perspectives a study was conducted in tropical environment to evaluate the total

Cross-linked enzyme aggregate (CLEA), a new method of carrier free enzyme immobilization has many advantages and considered as an economical method in the context of industrial biocatalysis. In this research, a highly active and stable CLEA-lipase has been successfully prepared from cocoa pod husk (CPH), a by-product of the cocoa industry. Based on

Objective: To assess the social-demographic characteristic and the maternal risk factors for pre eclampsia (PE) especially maternal fasting serum lipids (FSL) between trimesters. It was also to find out the association between FSL with fetal birth weight at a primary maternal child health center (KKIA). Materials and methods: A prospective cohort s

This study compared two collection methods for Gambierdiscus and other benthic harmful algal bloom (BHAB) dinoflagellates, an artificial substrate method and the traditional macrophyte substrate method. Specifically, we report the results of a series of field experiments in tropical environments designed to address the correlation of benthic dinofl

The major challenge associated with cold microfiltration (MF) of skim milk is the decrease in permeate flux, caused by fouling. To address this, a novel CO2 backpulsing technique capable to counteract membrane fouling was developed and optimized. Five portable CO2 backpulsing ports were attached to the membrane housing. Five different combinations

Purpose: The purpose was to determine the within-session variability and between-session repeatability of SD-OCT Doppler measurement of retinal blood flow in young and elderly healthy subjects. Methods: SD-OCT Doppler blood flow was non-invasively measured using the RTVue system (Optovue Inc., USA). One eye of each of 6 healthy young (mean age 25.7

The electroosmotic dewatering (EOD) behaviors of gelatinous materials, such as superabsorbent hydrogels or swelling clay, are discussed. The apparent liquid velocity through the materials can be represented in terms of effective-osmotic, electroosmotic and swelling pressure gradients. Taking the creep deformation of the materials into consideration
