In this study, biodiesel was produced from sludge palm oil (SPO) using tolune-4-sulfonic monohydrate acid (PTSA) as an acid catalyst in different dosages in the presence of methanol to convert free fatty acid (FFA) to fatty acid methyl ester (FAME), followed by a transesterification process using an alkaline catalyst. In the first step, acid cataly

In this study sulphuric acid has been used in pre-treatment of sludge palm oil for biodiesel production by esterification process. The purpose of pre-treatment process was reducing the free fatty acids (FFA) content in the sludge palm oil (SPO) to a minimum level for biodiesel production. Esterification process of SPO was carried out to evaluate su

A reverse phase high performance liquid chromatographic method for the detection of the neurotransmitters namely serotonin, tryptophan and dopamine in human blood samples has been developed. Spiked standard samples were analysed using a fluorescence detector after chromatographic separation. For the analytes a working range of 2.5 ng/mL to 25 ng/mL

The reduction of free fatty acids (FFAs) in sludge palm oil (SPO) was measured at different sonication time from 30 to 300 min and the optimum time was determined. It is reasonable to indicate that the pretreatment of SPO by applying ultrasonic energy is related to long sonication time. The results showed that the FFA content of SPO reduced from 24

Computer generated speech replaces the conventional text based interaction methods. Initially, speech synthesis generated human voice that lacked emotional expression. This kind of speech does not encourage users to interact with computers. Emotional speech synthesis is one of the challenges of speech synthesize research. The quality of emotional s

Herbal or traditional remedies have been used to cure different ailments since pre- historic times. The use of recorded herbal medicines can be traced back to about 5000 years ago when the Sumerian's used plants such as thyme and laurel as a remedy for ailments. According to the WHO report at present about 70 to 80 percent of world population i

p53 gene has been hailed to have important roles in maintaining genomic integrity. The critical roles of this tumor suppressor in cell cycle, DNA repair, and opoptosis profoundly contribute to development of cancer. p53 mutations have been found in almost fifty percent of all cancer types, including lung cancers. Hence, the idea of restoring the no

Use of traditional medicine and health supplements as complementary and alternative medicine is getting popular worldwide. The popularity of traditional medicine and health supplements causes high demand of these products. Proper quality control measures should be taken prior to marketing of these types of medicines and supplements to assure the sa

خلاصة: تساءل كثير من المسلمين طيلة العقود الأربعة الماضية: هل كل الليبيين راضون بحكم القذافي؟ هل يحبونه؟ أين أنتم يا ليبيون؟ لماذا لم تثوروا على الظلم يا أحفاد المختار؟ يعتقد الكاتب أن ثورة 17 ف
