The present study involves two processes; modification of the tool holder for use with cryogenic cooling system, and implementation of the new design and testing its effect on tool life and product quality. Liquid nitrogen, which is the most suitable fluid for cryogenic machining is used in this work. Two different flow outlets were tested for this

This study was carried out to investigate the effect of Hibiscus sabdariffa or roselle on the progression of acute liver injury in rats. The liver injury was induced by administration of 1000 mg/kg acetaminophen intraperitoneally and aqueous extract at low (500 mg/kg) and high (1000 mg/kg) doses of H. sabdariffa was given to rats by force feeding.

Consumers’ confidence on the online transactions is vital for the continuous growth and development of electronic commerce. In the present study, we experimentally investigate the measures of consumers’ perceived security and privacy over online transactions as well as the perceived trust and reliability of online vendors in order to influence

Thermoplastic natural rubber (TPNR) nanocomposites containing organophilic layered silicates were prepared by melt blending method at 180 �C using internal mixer (Haake 600P). The aim of this study is to determine the influence of the organoclay filler on the mechanical and fracture properties. In this study, two mixing methods were employed to i

Andrographis paniculata is a Malaysian traditional herb for treatment of fever-causing diseases and diabetes. The aim of the present study was to examine the antihyperglycemic effects of different extracts (95, 50, and 20% ethanol extracts and water extracts) of A. paniculata in normal and streptozotocin-induced diabetic rats. Only the treatment wi

This research paper aims to develop an isolated-word automatic speech recognition (IWASR) system based on Vector Quantization (VQ). This system receives, analyzes, searches and matches an input speech signal with the trained set of speech signals which are stored in the database/codebook, and returns matching results to users. IWASR is meant to ass

Three different NP antigenic sites were identified using deleted truncated NP mutants purified from Escherichia coli. One of the antigenic sites was located within amino acids 441 to 489 of C-terminal. Two other antigenic sites located within the Nterminal of NP protein from amino acids 26 to 121 and 122 to 375 residues. Identification of NP antige

Experimental and finite element analyses for hybrid and non-hybrid glass and carbon/epoxy composites tubes subjected o quasi static lateral indentation loading have been carried out. Four types of composites tubes each of four layers and approximately 1.6 wall thickness were fabricated by filament winding process. Tube length and inner diameter are

Throughout human history, conflict has been the human experience. We are now living in global era and changing world, but the potential to destroy is the certain fact that ever-increasing in step with the technological revolution. Parallel to this was great contributions has been made for understanding of conflict as a social interaction phenomena,

The awqaf institutions are, perhaps the less developed Islamic financial institutions compared to banking, insurance and zakat. However, these institutions are numerous and widespread all over the world, particularly in the countries where Muslim population is in existence. The attention to awqaf institutional development just took place in the las
