Research ArticleOpen accessEvery word in the titleSOFT COMPUTING APPROACH TO PREDICT INTRACRANIAL PRESSURE VALUESMario VersaciThe estimation and the prediction of the values related to the Intracranial Pression (ICP) represents an important step for the evaluation of the compliance of the human brain, above all in those cases in which the increase of the ICP values determines high risk conditions for the patient. The regular therapy is neuro-surgical but, waiting for it, it is needed … …American Journal of Applied Sciences, Vol. 11, Issue 5 · 7 Mar 2014 · 6,674 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInfluence of Time, Temperature and Pressure on the Creasing of Wool/Polyester Blended FibersBrian F.G. KatzStudies investigating the response of a natural/synthetic blended material to variations of time, temperature and pressure with respect to induced deformations have been carried out. Such a material is interesting due to its complexity of responses which are dependent on the nature of each fiber. The study’s sample was a wool/polyester blend with a 45/55 composition respectively. This combination is … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 4 · 23 Dec 2021 · 6,397 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleRHEOLOGICAL PROPERTIES OF PADDY SOIL UNDER VARIOUS PRESSURE, WATER CONTENT AND TOOL SHAPESI. A. Mari, C. Ji, F. A. Chandio et al.In this study Burger’s four element model was used to analyze rheological parameter of paddy soil of the Southern China. Two types of tool shape include circular shape (with an area of 12.56 cm2) and rectangular shape (with an area of 12.56 cm2) were use to measure the rheological parameter of paddy soil under different loading pressure (7.65, 10.20 and … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 1 · 14 Dec 2013 · 7,513 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDensity Equation of Cassava-Stalk Briquettes Under Moderate Die-PressurePatomsok WilaiponProblem statement: Agricultural residues seem to be the most promising energy resources for developing countries. However, the majority of them have low energy density. One of the favorable technologies for enhancing that property is briquetting. For the case of Phitsanulok, a province in Northern Thailand, cassava is one of the most important crops. Therefore, a large amount of cassava stalk … …American Journal of Applied Sciences, Vol. 7, Issue 5 · 31 May 2010 · 7,285 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleClassification of Pressure Range Based on the Characterization of Escherichia coli Cell Disruption in High Pressure HomogenizerRamakrishnan Nagasundara Ramanan, Beng Ti Tey, Tau Chuan Ling, Arbakariya B. AriffProblem statement: High pressure Homogenizer was used for cell disruption in many studies. But no work was carried out to study the characteristics of cell disruption in a wide range of pressure. Approach: The characteristics of Escherichia coli cell disruption was studied in Avestin small scale homogenizer by varying the operating pressure (50-1500 bar), cell concentration in the feed (1.39-12.51 … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Mar 2009 · 9,626 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Effects of Briquetting Pressure on Banana-Peel Briquette and the Banana Waste in Northern ThailandPatomsok WilaiponBanana is considered as one of the most important agricultural products of Northern Thailand. A large amount of banana peel has been left as garbage after industrial processes. The raw material is plentiful and has low economic value. Therefore, the characteristics of banana-peel briquettes including banana peel properties were investigated. The briquettes were produced with pressures ranging from 3 to … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 11,911 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNew Analysis for The FGM Thick Cylinders Under Combined Pressure and Temperature LoadingK. Abrinia, H. Naee, F. Sadeghi, F. DjavanroodiAn analytical solution for computing the radial and circumferential stresses in a FGM thick cylindrical vessel under the influence of internal pressure and temperature is presented in this paper. It has been assumed that the modulus of elasticity and thermal coefficient of expansion were varying through thickness of the FGM material according to a power law relationship. Nevertheless the value … …American Journal of Applied Sciences, Vol. 5, Issue 7 · 31 Jul 2008 · 7,123 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Stent Geometry on Phase Shift between Pressure and Flow Waveforms in Stented Human Coronary ArteryVahab Dehlaghi, Siamak Najarian, Mohammad Tafazzoli ShadpourShear stress is known to play a central role in restenosis formation and is sensitive to stent geometry. Alterations of the phase shift between pressure and flow waveform created by a different stents were studied to compare the hemodynamic effects of stent design properties on restenosis in stented human coronary artery. Blood pressure waveforms were computed in three different sites, … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,252 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFluctuation of Brain Tissue Oxygen Partial Pressure: A Biochemical Landmark in the Arctic Ground Squirrel's Spontaneous ArousalYi Long Ma, Shu Fen Wu, Lawrence K. DuffyHibernation in the Arctic ground Squirrel (AGS) is a regulated, adaptive response to arctic environmental conditions. Problem statement: Regional brain Blood Flow (rCBF) has been observed to increase dramatically during arousal in hibernators. However, the real time dynamic change in PtO2 during arousal has not been studied, we hypothesized that PtO2 is Interdependent of Tbrain and a key component in … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 4 · 1 Feb 2012 · 7,601 accessesView PDFCite
