Accepted: 08/06/2014 Abstract Six variety of betel leaf from different domain of India were extracted using five solvents in order to determine the effect of solvent and changing variety on total phenol content and antioxidant activity. Antioxidant activity was determined using DPPH, ABTS, FRAP, PCL (Photochemluminiscence) assay. However 80% methanol for TPC, 80% ethanol followed by 80% methano...

The aim of this study was to optimize the extraction conditions for the extraction of phenolic compounds from Moringa oleifera leaves using response surface methodology (RSM). A user-defined design was applied to determine the effects of extraction time (min), extraction temperature ((o)C) and ethanol concentration (%), on total phenolic content (TPC) from Moringa oleifera leaves dried by three...

We report on the performance of a micro-TPC with a micro pixel chamber(μPIC) readout for a time-resolved neutron position-sensitive detector(PSD). Threedimensional tracks and the Bragg curves of protons with energies of around 1 MeV were clearly detected by the micro-TPC. More than 95% of gamma-rays of 511 keV were found to be discriminated by simple analysis. Simulation studies showed that the...

This paper presents findings of a study of high school students participating in a tablet PC (TPC) programme. Primary areas of interest were students' experiences with and attitudes about the TPCs, physical discomfort associated with use of TPCs and temporal and task-driven patterns of TPC use. Data were collected via questionnaire and computer use-monitoring software. Results showed students' ...

Germinated brown rice (GBR) is considered a healthy alternative to white rice in the fight against chronic diseases. As the functional quality of GBR depends on genotype and germination conditions, the objectives were to identify suitable Ecuadorian brown rice cultivars and optimal germination time and temperature to maximise γ-aminobutyric acid (GABA), total phenolics compounds (TPC) and antio...

This paper evaluates the performance of single-parity check turbo product codes (TPC/SPC) over partial response channels. A rate-0.94 and a rate-0.89 TPC/SPC code are considered for use with PR4/EPR4 channels with proper precoding and with turbo equalization. Gains of 4.5 to 5 dB are obtained at BER of 10 , revealing performance comparable to that of low density parity check codes. Apart from i...

TPC-E is the new benchmark approved by the TPC council. It is designed to exercise a brokerage firm workload, which is representative of current On-Line Transaction Processing workloads. In this paper we present DBT-5, a fair usage open-source implementation of the TPC-E benchmark. In addition to reporting about the design and implementation of the tool, experimental results from a system runni...

were limited in their ability to manipulate data values at the byte and word granularity. Instead of allowing single instructions to manipulate byte and word values, the original Alpha Architecture required as many as sixteen instructions. Recently, DIGITAL extended the Alpha Architecture to manipulate byte and word data values with a single instruction. The second generation of the Alpha 21164...
