In a demand feeding system, the fish turn on the switch of the feeder to get feed. In order to develop a demand feeding system with an infrared light sensor to which juvenile tiger grouper, Epinephelus fuscoguttatus visually respond, the visual acuity and visual axis of the juveniles were determined to obtain fundamental understanding of their visi

Hydroxyapatite (HA) is the main mineral component of bone tissue, representing ca. 69 vol% in bone and up to 98 vol% in dental enamel. Its chemical composition close to the mineral phase of bone is the origin of its excellent biocompatibility to tissue bone. Hydroxyapatite has been applied in orthopaedics as block implants, porous, granules and coa

In the title compound, C21H24N2O3, the mean planes of the benzene ring and the benzimidazole ring system form a dihedral angle of 69.94 (7)�. The ethyl group atoms of the ethanoate fragment are disordered over two sets of sites, with refined occupancies of 0.742 (6) and 0.258 (6). In the crystal,there are weak C—H� � �N hydrogen bonds whi

This work aims at optimizing the media constituents for citric acid production from oil palm empty fruit bunches (EFB) as renewable resource using artificial neural network (ANN) approach. The bioconversion process was done through solid state bioconversion using Aspergillus niger. ANN model was built using MATLAB software. A 20 dataset of an earli

The main aim of this paper is to investigate the properties of Cu-TaC electrodes produced by Powder Metallurgy (PM) method. The design of Experiment (DOE) method was used to plan the investigation. Two different compositions of the powders (Cu-TaC with 30 and 55 % wt TaC) were used. The major properties which determine suitability of electrodes for

نفترض أن عولمة التخلف -بإيجابياتها الفاشلة وسلبياتها الناجحة- تفضي إلى فراغ اقتصادي وتقني في العالم العربي؛ حيث التعامل مع الفراغ لا ينتج عنه إلاَّ الفراغ. فعالم فقيرٌ اقتصاديًا وتكنولوجيًا،

Vesicular drug delivery system like liposomes and niosomes, sometimes drugs are not delivered in a desired manner because of aggregation, sedimentation, stability problems and tedious method of production. By using ‘Proniosomes’ as carrier for drug delivery these problems of drug delivery can be reduced because they are easy to prepare and havi

The paper aims to improve the security of the credit card online purchasing with taking into account the time and cost issues. Since the current online purchasing system using credit card has security drawbacks, a security improvement is suggested in this work by implementing a model which integrates the current authentication system of credit card
