The coil design of the inductive power transfer (IPT) for a transmitter (Tx) and receiver (Rx) is crucial to determine performance IPT. Considering core loss copper Tx Rx coils, which are major terms whole IPT system, determination winding turns coils becomes key factor maximum coils. In this paper, an optimal laptop wireless charging applications with efficiency proposed. Under specific requir...

Jerawat (Acne vulgaris) merupakan penyakit inflamasi kronik yang terjadi pada unit pilosebaseus. Infeksi dapat disebabkan oleh Propionibacterium acne dan Staphylococcus aureus. Daun sirsak Herba meniran diketahui menghambat pertumbuhan jerawat mampu membunuh bakteri. Penelitian ini bertujuan untuk mengetahui efektivitas sediaan gel kombinasi kedua ekstrak dalam bakteri penyebab (Propionibacteri...

Mucoadhesive buccal tablets containing ondansetron hydrochloride (ODH) were prepared using polymers like gelatin, chitosan, xanthan gum in varying concentration of 5, 10, 15% w/w and HPMC K4M 40% w/w by direct compression technique. Precompressional studies revealed good micromeritic properties of powder blend for compression and were found as per literature limits. The prepared tablets were ev...

Omeprazole (OME) is a proto type anti-secretary agent. This compound is very unstable, especially in acidic aqueous solutions. A stability indicating HPLC assay has been developed in order to investigate the effect of different factors on the stability of omeprazole. These factors included the pH with the tested values ranging from 6-10 and the temperature by monitoring the drug stability at 25...

In this study, we investigate the interaction of Rhodopseudomonas Palustris (R. Palustris) with montmorillonite clay. The adsorption of bacteria on the clay surface was also determined as a function of the initial bacterial quantity, pH, temperature and ionic strength. At different initial bacterial quantities, the percentage of bacteria adsorbed ranged from 61.07% to 77.57%, and the higher per...

The present study describes the production, purification and characterization of alkaline protease from mutant strain of Bacillus subtilis EMS-8. The enzyme was purified using ammonium sulphate precipitation which gave 2.64 fold purification with 81.5% yield at 70% saturation. The molecular weight of the enzyme was determined using SDS-PAGE and it was found to be 25 KDa. The optimum pH of enzym...

Ultrasonic technology is widely used to assist many industrial and domestic applications. However, the effect of ultrasonic washing on the thermophysiological properties of natural based fabrics has not been studied yet. This study aims to examine the relationship between unwashed, ultrasonically washed, and conventionally washed fabrics in terms of their abrasion behavior, flexural rigidity, a...

The synthesis of fatty acid ethyl ester from chicken fat waste using ZnO/SiO2 heterogeneous catalyst was carried out using two-step procedures of acid pretreatment by esterification and transesterification of the pretreated oil. The first step reduces the high free fatty acid in the oil to an acceptable level for transesterification using concentrated sulphuric acid at a temperature of 60 oC du...

In this work an HPLC stability-indicating method was developed and applied to study the hydrolytic behavior of pravastatin in different pHs and temperatures. From the system suitability test, the selected chromatographic conditions were a C-18 column, acetonitrile-30 mmol L-1 phosphate buffer solution pH 2 (28:72) as mobile phase, 40oC temperature column, a flux of 1 mL/min and 239 nm as wavele...

In this research, the formation and development of aerobic granular sludge (AGS) for domestic wastewater treatment application in hot climate conditions was studied using a sequencing batch reactor (SBR). The performance of the developed AGS in the removal of organic matter and nutrients from wastewater was also investigated. The operation of the reactor was based on the sequencing batch system...
