ABSTRACT
Warm-up is an essential part of preparation for rowing, especially in competitions. Respiratory muscle warm-up has been proposed to be the beneficial warm-up protocol for enhancing rowing performance. Therefore, the aim of this study is to determine the effect of inspiratory and expiratory muscle warm-up on rowing performance. The design...

ABSTRACT
This paper presents the small-signal modeling of a Single-Ended Primary Inductor Converter power stage operating in discontinuous conduction mode using the sampled-data modeling technique. In addition, two algebraic manipulating features are revealed; the simpler periodic solution determination by the concept of Volt-Second and Capacitor-Charge balance, and the replacement of the...

ABSTRACT
Cyclodextrin glycosyltransferase (CGTase) catalyzes an intermolecular transglycosylation reaction to produce functional oligosaccharides or glycosides, which can be used in several industries. In this study, the p19bBC recombinant cells containing CGTase gene from Bacillus circulans A11 were used for synthesizing CGTase. The maximum expression was obtained when the p19bBC cells were...

ABSTRACT
Oil palm is an oil plant which is of great importance for both the Thai and the world economies. Oil palm trees have a life span of approximately 20-25 years before a gradual erosion of yield sets in. Oil palm trunk (OPT) is an agricultural residue waste from oil palm...

ABSTRACT
The study investigated the soxhlet extraction of Leum Pua rice bran oil (Oryza sativa L.) using 12 hours of extraction time, with comparison of product with hexane and ethanol as solvent. The chemical properties and gamma-oryzanol content in the rice bran oil were investigated. The results showed that the highest...

ABSTRACT
This paper examines intrinsic characteristics of the integral control of a PID controller, and points out one that can cause excessive overshoot when the reference signal changes abruptly. Reasons for not totally relying on the derivative control to suppress overshoot are discussed, and then augmentation of an adaptive integral gain...

ABSTRACT
This study investigated the phytochemical screening and biological activity of Sesbania grandiflora ( L. ), locally named as "Khae ban", bark extractions, which were soft and hard barks. The phytochemical screening was carried out on the extraction of each particular bark with 95% Hexane, 95% Ethyl acetate, and 95% Ethanol...

ABSTRACT
Vibrio cholera, Vibrio parahaemolyticus and Vibrio vulnificus are opportunistic pathogens causing disease in weak shrimp and possible food poisoning in shrimp consumers. In this study, three pairs of primers were designed to amplify the target DNA fragments of three Vibrio spp. and together with one pair for internal amplification control....

ABSTRAK
Researchers have evolved several empirical studies with numerous statistical operations for processing of vast Climatic data. However, certain short comings exist in the methodologies as the efforts to quantify the high resolution observations is at most times inappropriate, inaccurate, tedious, complex and expensive. One of the most documented anthropogenic impressions...
