An integrated low-cost adsorption (with powdered activated carbon) and cross-flow membrane filtration (with microfiltration membranes of 0.1 and 0.2 μm pore sizes) process was employed for the treatment of biotreated POME to produce irrigation water fully benchmarked with water-quality standards. The permeate quality was within the recommended sta

In this study, the potential of an improved empty fruit bunch-based powdered activated carbon (PAC) with high surface area was employed in removing suspended solids and turbidity from a high-strength wastewater. Also, the effects of operating parameters, such as PAC dosage, contact time and mixing speed on sorption trends of the two pollutants from

This study aimed to investigate the effects of the ultrasound-assisted extraction conditions on the yield, specific activity, temperature, and storage stability of the pectinase enzyme from guava peel. The ultrasound variables studied were sonication time (10-30min), ultrasound temperature (30-50 degrees C), pH (2.0-8.0), and solvent-to-sample rati

A statistical analysis was performed first to evaluate the effect of factor and to obtain the optimum configuration of Kraft paper honeycomb. The factors considered in this study include density of paper, thickness of paper and cell size of honeycomb. Based on the three level factorial design,two-factor interaction model (2FI) was developed to corr

Emotion modeling and identification has attracted substantial interest from disciplines including computer science, cognitive science and psychology. Despite the fact that a lot of qualitative studies have been carried out on emotion, less investigated aspects include the quantifying of physiological signals. This paper presents two physiological s

Abstract: Soda lime glass is used extensively in engineering application owing to its high hardness, excellent optical properties, and good corrosion and chemical resistance. Previous studies on ductile mode machining were conducted with the application of negative rake angle of the tool in order to achieve high hydrostatic pressure in the cutting

There is a misunderstanding among some students and scholars of Islamic jurisprudence that if a Qur’anic or Sunna’ic text is available on a particular issue, in order to derive the rule for this issue, neither is ijtihad required nor is it allowed. Rather, this text is sufficient to know the rule and implement it. This misunderstanding goes bac

A novel aqueous micellar two-phase system composed of surfactant and mannitol was employed for the first time to purify polygalacturonase from Durio zibethinus Murray. The influences of different parameters such as type of surfactants, composition of surfactant/mannitol, pH and crude load on polygalacturonase partitioning were investigated. The res

وُجد في هذا العصر كثير من المستجدات الفقهية تبعاً للتطور العلمي المعاصر، ومن هذه المستجدات ما يتعلق بأحكام المفطرات المعاصرة، وعليه اخترت البحث في هذا الموضوع، وربطت بين الأصالة والمعاصرة وذ

The purpose of this study was to investigate the effect of using computer simulation to develop physics problems solving skills for second class’ students in secondary schools at Sana'a state and their attitudes towards Physics. To fulfill this goal, two scales were built; scale of physics problems solving skills, and scale of attitudes towar
