This study aims to determine the antibacterial activity of Pliek U ethanol extract cream against Staphylococcus aureus. The method was an experimental with a completely randomized design (CRD) on five treatments, namely positive control, negative F1, F2, and F3, each four repetitions. Antibacterial testing carried out using disc diffusion method. results showed that average diameters F2 F3 were...

The English /l-r/ distinction is difficult to learn for some second language learners as well as for nativespeaking children. This study examines the use of the second (F2) and third (F3) formants in the production and perception of /l/ and /r/ sounds in 4-, 5and 8-year old native-English-speaking children. The results indicate that whereas the young children’s /l/-/r/ production was welldistin...

Psyllium is a viscous, gel forming fibre with properties that have led it to be used for alleviating gastrointestinal discomfort. We previously identified fractions of psyllium differing flow properties. Fraction 1 (F1) forms non-gelling solution containing rhamnose. galactose, and arabinose. 2 (F2) fluid-like mainly xylose arabinose, 3 (F3) has almost identical monosaccharide linkage compositi...

The root-lesion nematodes Pratylenchus neglectus and P. thornei are economically damaging pathogens of wheat in the Pacific Northwest (PNW). Growing resistant and tolerant varieties is the best approach to minimize yield loss. All PNW wheat varieties were found to be susceptible. Crosses were made between the PNW-adapted varieties (Alpowa Louise, Otis) and the Australian wheat GS50a with resist...

With synthetic stimuli copied from natural vowels and including up to five formants, we investigated some transformations of the perceived identity of vowels by means of modifications of formant amplitude levels. Synthetic stimuli were generated by means of a new method of copy synthesis. With stimuli copied from /u/ we found that, despite the presence of F2, it is possible to transform the tim...

Jeruk Kalamansi (Citrofortunella microcarpa) merupakan salah satu komoditi pertanian yang telah banyak dikembangkan di Provinsi Bengkulu. Kalimansi mengandung kadar Vitamin C tinggi sebesar 3,863 mg/100 g namun memiliki rasa asam sehingga kurang enak dikonsumsi langsung. Hal ini mendorong peneliti untuk membuat dalam bentuk permen jelly jenis produk digemari oleh berbagai kalangan usia, khususn...

This study aims at investigating the acoustic correlates of supralaryngeal and muscular tension voice quality settings (VQS). Speech samples from 40 speakers were perceptually analyzed by means of the Vocal Profile Analysis Scheme (VPAS). Acoustic analysis comprised formant frequency (F1, F2 and F3) and intensity measurements (I1, I2 and I3) of seven Brazilian Portuguese vowels. Multivariate st...

background and objectives: although chemical fertilizers in short-term can increase vegetables yield, but must be renewed each planting season that this trend increases the concentration of nitrate in the vegetables shoots, nitrogen leaching and contamination of water resources, loss of beneficial insects and microorganisms and soil fertility will decline, and over time reduce the yield and qua...

Buthotus schach is one of the dangers scorpion in Iran that belong to the Buthidae family. Toxins are existing in venom scorpion, modulate the ion channels by blocking or opening the pore of the channel or by altering the voltage gating and useful as pharmacological tools. In the present study, we investigated the effect of venom and its obtained fractions by gel filtrations on electrophysiolog...
