Tea (Camellia sinensis L.) fruit peel, the main byproduct during the manufacture of tea seed oil, was used as raw material for the recovery of phenolic antioxidants. The effect of ethanol concentration, extraction time, and extraction temperature on total phenolic content (TPC) and ferric-reducing antioxidant power (FRAP) of the extracts from tea fruit peel was investigated. The maximum predict...

Three different concentrations of clove oil were applied to two different size groups of singhi (Heteropneustes fossilis) and lata (Channa punctatus) fish to observe the anaesthetic effect and to find an optimum dose. Two groups each consisting of 10 fish was exposed to 0.01, 0.02 and 0.03% clove oil. All fish of either size anaesthetized with 0.01% clove oil exhibited longer induction and shor...

This paper explores the recovery and rate capacity effect for batteries used in embedded systems. It describes the prominent battery models with their advantages and drawbacks. It then throws new light on the battery recovery behavior, which can help determine optimum discharge profiles and hence result in significant improvement in battery lifetime. Finally it proposes a fast and accurate stoc...

Introduction: MRI is becoming a widely used tool in cardiovascular research involving small animals, and is regarded as the gold standard for assessing many functional parameters, such as ejection fraction. However, the assessment of myocardial infarction by delayed enhancement (DE) using gadolinium contrast agents, has not seen as widespread use in small animal research, and studies have prima...

Abstract Tannic acid–acetic acid is proposed as novel and green chemicals for cobalt lithium recycling from spent lithium-ion batteries through a leaching process. The synergism of both acids was documented batch continuous studies. promotes dissolution by reducing insoluble Co 3+ into soluble 2+ , while acetic critical to improve the stabilize metals in pregnant leach solution. Based on studie...

application of cogeneration systems based gas turbine for heat and power production is increasing. because of finite natural energy resources and increasing energy demand the cost effective design of energy systems is essential. cgam problem as a cogeneration system is considered here for analyzing. two new approaches are considered, first in thermodynamic model of gas turbine and cogeneration ...

Materials and methods This was a cross-sectional study of 91 stroke patients; mean age 58.9±10.6 years, 79% male, median stroke duration 13 months who have completed intensive individual rehabilitation at the Universiti Kebangsaan Malaysia Medical Centre in the years 2010 and 2011. Rehabilitation outcome was measured with the use of standardised tools; Rivermead Mobility Scale (RMI), Berg’s Bal...

Energy recovery from waste heat is attracting more and more attention. All electronic systems consume electricity but only a fraction of it is used for information processing and for human interfaces, such as displays. Lots of energy is dissipated as heat. There are some discussions on waste heat recovery from the electronic systems such as laptop computers. However the efficiency of energy con...

We present a two stage technique for estimation of rigid body motion and scene structure from monocular image sequences. The robustness of motion recovery is considerably increased by motion dependent distortion of rectangular measurement windows. In the rst stage, we estimate a set of candidate motion parameter sets from which the optimum is determined in a second step evaluating motion based ...
