Bioethanol production from the yeast Yarrowia lipolytica biomass was studied. The effects of temperature (90-150°C) and H2SO4 concentration (2-15%w/w) on the saccharification of biomass at a hydrolysis time of 1h were investigated. A maximum glucose concentration of 35.89g/L can be produced from defatted biomass using 6% H2SO4 at 120°C. Subcritical water (SCW) pretreatment has negligible effect on maximizing glucose yield. Only 14.53g/L glucose can be produced using 6% H2SO4 at 120°C if un-defatted biomass was used. The highest ethanol concentration achieved was 13.39g/L with a corresponding ethanol yield of 0.084g/g dry biomass (0.38g ethanol/g glucose). © 2012 Elsevier Ltd. Source

Using a sample of Indonesian university students and a cross sectional design, this study investigated prevalence rates and patterns of pornography consumption in Indonesia, a religious, sexually conservative, Muslim-majority nation with strict anti-pornography laws. Further, the association between pornography consumption and common non-marital sexual behaviours was explored. The study found that in this sample, pornography is as widely and readily consumed as in comparable international studies predominantly utilising Western background samples from more sexually liberal and less religious countries with very few laws on pornography. Gender differences in patterns of pornography consumption were pronounced and comparable with findings in international counterpart studies. For men only, pornography consumption was found to significantly predict common sexual behaviours in non-marital relations. The study is the first to provide insights into prevalence rates and patterns of pornography consumption and its association with common non-marital sexual behaviours in a sexually conservative, Muslim-majority nation with strict anti-pornography laws. © 2013 © 2013 Taylor & Francis.

Intoxication of lead (Pb) causes the formation of free radicals that affect the antioxidative defense system, thus speeding up cell damage. Soybean (Glycine max L. Merr) Ijen is one of the varieties of food containing phenolic compounds and flavonoids, which have antioxidant activity. Experimental animals used in this study were the Mus muscullus Balb / c as much as 25 tails, they were divided into 5 groups: placebo, negative control, positive control, test and comparison groups. The negative control, test and comparison group were given Pb at a dose of 25 mg / kg orally for 7 days. After the stages of intoxication, positive control and test groups were given suspensions extract of soybean Ijen varieties at a dose of 1g/1 ml for 7 days, the comparison group was given a suspension of vitamin C supplementation at a dose of 64 mg / kg orally for 7 days, and the negative control group were given mucilago CMC Na 0,5% of 1 ml for 7 days. Liver tissue of mice were used to analyze the activity of the catalase enzyme and malondialdehyde (MDA) level. Kidney's tissues were used for histopathological examination. Extract of soybean (Glycine max L.Merr) Ijen varieties decreases the activity of the enzyme catalase and repair damaged Kidneycells of mice that lead intoxication as effective as vitamin C. Source


Student engagement has long been known can increase the student performance. However bring this concept to practice may not be as easy as it sounds. Some factors, such as the teacher, the students and their background, the course content, the academic atmosphere, the study culture, etc., influence its implementation. This paper presents the practice that is applied in the Informatics Department of the University of Surabaya to enhance the student engagement in the introductory programming course (i.e. Algorithm and Pro- gramming). This course is one of the course that is commonly known as difficult and make many Informatics students in the University of Surabaya dropped their study in the Department. The practice to enhance the student engagement in the Informatics Department of the University of Surabaya is designed to fit best with the condition in the Department. As a result, the students’ perfor- mance increase two grade level compared to the students’ performance in the previous years. © Springer-Verlag Berlin Heidelberg 2015. Source

The fulfilment of customers' emotional needs (Kansei in Japanese) tends to be highly expected, especially in growing industries such as the service industry. Recent research shows that emotion is just as important as cognition in service-related encounters. Thus, service providers should not overlook the significant roles of both emotional and cognitive aspects in achieving service excellence for customers. In modeling how to capture and translate customers' emotional needs into services, Kansei Engineering (KE) is used. This study aims to integrate Kansei Engineering with the Kano model and the Theory of Inventive Problem Solving (TRIZ). The Kano model is used to identify the relationship between service attribute performance and customer satisfaction, whereas TRIZ is utilized subsequently to generate designs for improvement with the lowest contradiction between the proposed service design solutions. Due to relatively unexplored cultural differences in Kansei research, cultural factors are also considered and incorporated into the integrated model. It is hoped that further insight into the emotional needs of customers from different cultural backgrounds will be better understood, so that the improvement strategies will be suitable. In addition, to illustrate the applicability of the integrated model, an empirical study in a medium-sized restaurant that takes into account both Indonesian and non-Indonesian customers will be discussed. © IJTech 2016.
