Research ArticleOpen accessIn the abstractAn Investigation of Compressed Natural Gas Engine for Nitrogen Oxides ReductionP. M. Diaz, B. Durga PrasadProblem statement: This study describes the use of Reformer Gas (RG) to alter NOx emission in a CNG-fueled HCCI engine. Comparison with diesel, natural gas has a very high octane number (≈120) and high auto-ignition temperature (≈600°C). Composed mostly of methane, natural gas is the only common fuel to manifest relatively pure, single-stage combustion. Other fuels have stronger low-temperature reaction … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 15 May 2012 · 7,299 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Dry Ice Application in Fish Hold of Fishing Boat on the Fish Quality and Fisherman IncomeSemin, Alam Baheramsyah, Amiadji, Abdul Rahim IsmailProblem statement: This study presents the effect of dry ice application in the fish hold of fishing boat on the fish quality and fisherman income. Dry ice is made with compressed CO2 gas to produce hot, high-pressure gas. Hot gas then cooled to condense into liquid CO2, which is still high pressure. Dry ice can be used to cool a … …American Journal of Applied Sciences, Vol. 8, Issue 12 · 11 Oct 2011 · 8,106 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssociation of Anthropometric and Metabolic Variables with Cardiovascular Disease among Urban and Rural OriginBadaruddoza, Kushal Gill, Raman KumarProblem statement: We have examined the prevalence and association of cardiovascular diseases with respect to obesity and metabolic risk factors clustering among urban and rural Punjabi males aged 20-55 years. Obesity has been defined by increased Waist Circumference (WC), Body Mass Index (BMI) and Waist Hip Ratio (WHR). Metabolic traits such as increased total cholesterol, triglycerides and lipoproteins have also … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 20 Aug 2011 · 7,472 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Hyperoxia on Brain Tissue Oxygen Tension in Non-Sedated, Non- Anesthetized Arctic Ground Squirrels: An Animal Model of Hyperoxic StressYilong Ma, Shufen Wu, Lawrence DuffyArctic Ground Squirrels (AGS) are classic hibernators known for their tolerance to hypoxia. AGS have been studied as a model of hypoxia with potential as a medical research model. Problem statement: Their unique resistance to the stressors of low oxygen led us to hypothesize that AGS might also be adaptable to hyperoxia. Approach: This study examined the physiological pattern associated … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 1 · 26 Apr 2011 · 8,476 accessesView PDFCite
Research ArticleOpen accessIn the abstractRecycled High-Density Polyethylene and Rice Husk as a Wetted Pad in Evaporative Cooling SystemNitipong Soponpongpipat, Sukum KositchaimongkolProblem statement: The low cost and easy-to-find materials, for being used as wetted pad of evaporative cooling system, are necessary for agriculture. This study, thus, studied the evaporative cooling efficiency and pressure drop of recycled High-Density Polyethylene (HDPE) and rice husk as a wetted pad in evaporative cooling system. Approach: The study was done by establishing the tested wetted pad … …American Journal of Applied Sciences, Vol. 8, Issue 2 · 28 Feb 2011 · 8,704 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Abutment Displacement of a Full Height Integral Bridges in Dense Granule BackfillM. H. Alizadeh, A.R. Khalim Rashid, Zamri Chik, S. M. MirhosseinyProblem statement: In this study, the behavior of abutment wall in full height frame integral abutment bridges was investigated. It was seen that the effect of backfill soil resistance on behavior of abutment wall movement is mostly neglected in previous studies. In this research, the final bridge superstructure displacement under temperature-induced forces was formulated. In addition, according to the final … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 30 Nov 2010 · 8,357 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransient in-Cylinder Gas Flow Characteristics of Single Cylinder Port Injection Hydrogen Fueled EngineM. M. Rahman, Khalaf I. Hamada, M. M. Noor et al.Problem statement: The variation of the in-cylinder gas flow characteristics for single cylinder port injection hydrogen fueled internal combustion engine was investigated through transient state simulation. Approach: One dimensional gas dynamics was described the flow and heat transfer in the components of the engine model. Special attention is paid to selection and correction of heat transfer correlation which describe of … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 8,653 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Fuzzy Controller for Water Level in Stream Boiler TankSurachai PanichProblem statement: The process control of steam boiler is very popular used in the industrial. The temperature of the water is transferred directly by electrical heater. The pressure will increase based on the changing of the temperature. The purpose of the control is to change the opening set point for the valve when the temperature and pressure in the tank … …Journal of Computer Science, Vol. 6, Issue 11 · 23 Oct 2010 · 8,041 accessesView PDFCite
Research ArticleOpen accessIn the abstractHow (Un)biased are Airport Security Screening Procedures? A Social-Cognitive ExperimentPoornima Madhavan, Jeremy R. BrownProblem statement: This research examined the role that social-cognitive biases such as gender biases and racial biases play in decision making processes during the screening of carry-on luggage at airports. This research is unique in that no research so far has addressed the social-psychological underpinnings of airport security screening procedures. Approach: Participants (n = 36) performed a computer simulated task … …Current Research in Psychology, Vol. 1, Issue 1 · 30 Jun 2010 · 8,013 accessesView PDFCite
Research ArticleOpen accessIn the abstractFinite Element Analysis of Composite Hardened Walls Subjected to Blast LoadsGirum S. UrgessaProblem statement: There is currently no standard design guideline to determine the number of composites needed to retrofit masonry walls in order to withstand a given explosion. Past design approaches were mainly based on simplified single-degree-of-freedom analysis. A finite element analysis was conducted for concrete masonry walls hardened with composites and subjected to short duration blast loads. Approach: The analysis … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 4 · 31 Dec 2009 · 7,276 accessesView PDFCite
