Bleaching treatment of kenaf fiber was performed in alkaline medium containing hydrogen peroxide solution maintained at pH 11 and 80 °C for 60 min. The bleached kenaf fiber was analyzed using Fourier Transform Infrared (FTIR) and X-ray Diffraction (XRD) analysis. The bleached kenaf fiber was then compounded with poly-(lactic acid) (PLA) via a melt blending method. The mechanical (tensile, flexu...

Introduction: Pulmonary hypertension (PH) is a significant complication and is poor prognostic factor for sarcoidosis. We evaluated various tests of diagnosis and treatment as well as the associations between PH and value of six-minute walk test (6 MWT) in sarcoidosis patients. Methods: This study was conducted with fifty patients with sarcoidosis. We grouped patients according to echocardiogra...

Phonetics attempts to describe and understand how speech is produced and perceived; phonology attempts to understand the patterning—in general, the behavior—of speech sounds in particular languages and in all languages. Is phonetics part of phonology? This straightforward question has received various answers at different points in the history of linguistics. In this paper I attempt to document...

Cells. HeLa cells (American Type Culture Collection, Rockville, Md.) were grown in 80 ml culture medium in Roux bottles. Cells were grown in Eagle's medium (7) which contained Hanks' balanced salt solution (1 1), 10% bovine serum, 100 @zg/mlstreptomycin sulfate, and 100 units/ml penicillin G. Bottles were incubated at 36°in an humidified atmosphere of 5% CO2 , and the cells were passed by tryp...

The aim of study was to extract pectin from papaya peel and study its physico‐chemical characteristics. Pectin was extracted using hydrochloric acid and citric acid, at different time, temperature and pH combinations. Extraction was done at temperatures 60°C, 70°C and 80°C for time 30 mins, 45 mins and 60 mins, and pH 2, 2.5 and 3.0 respectively. Using hydrochloric acid, the yield of pectin was...

6-Shogaol, a dehydrated form of 6-gingerol, is a minor component in ginger (Zingiber officinale Roscoe) and has recently been reported to have more potent bioactivity than 6-gingerol. Based on the thermal instability of gingerols (their dehydration to corresponding shogaols at high temperature), we aimed to develop an optimal process to maximize the 6-shogaol content during ginger extraction by...
