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

Single women’s issues and challenges are seldom the center of research. One of the factors is the invisibility of this group within the society. In Malaysia where the cultural emphasis is on family value and a sense of collectiveness, many still perceives being single as a deviation from the norm. As a result, many single women feel pressure to f

The sustainable development of Islamic banking services has motivated large numbers of depositors to choose Islamic bank services instead of the conventional bank. There are various factors that can persuade the depositors’ choice to choose Islamic bank. The present study examines the factors that persuade individuals’ behavioral intention to c
