Research ArticleOpen accessIn the abstractImproving the Quality of Ceramic and Cemented Carbide Cutting Inserts by Diamond GrindingTareq Ahmad Abu Shreehah, Rasheed Abdulateef AbdullahThe machining of hardened steel and other difficult-to-cut materials require high quality and progressive cutting tools to meet the growing requirements for increasing productivity, improving tool life and quality of the cutting process. This study deals with an experimental investigation on the quality improvement by diamond grinding of ceramic and cemented carbide cutting inserts, comparing it with conventional batch produced … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 7,194 accessesView PDFCite
Research ArticleOpen accessIn the abstractStudy of the Optical and Physical Roles of a Dielectric Laser Dye Solvent Which Affects on the Dye Laser OperationRiyad A.M. GhazyIt is well known that when the pump laser beam incidence on the laser dye liquid it will be absorbed. This absorption tends to heat the laser active medium, which is the laser dye solution. In view of this the correlated property of that active medium well change tends to shift the operated frequency and wavelength. Therefore, one of most … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,862 accessesView PDFCite
Research ArticleOpen accessIn the abstractBuilding Cost Comparison Between Conventional and Formwork System: A Case Study of Four-storey School Buildings in MalaysiaNuzul Azam Haron, Ir. Salihuddin Hassim, Mohd. Razali Abd. Kadir, Mohd Saleh JaafarThe Malaysian construction industry is undergoing a transitional change from an industry employing conventional technology to a more systematic and mechanized system. This new system is now known as the Industrialized Building System (IBS). This new method of construction can increase productivity and quality of work through the use of better construction machinery, equipment, materials and extensive pre-project planning. This … …American Journal of Applied Sciences, Vol. 2, Issue 4 · 30 Apr 2005 · 9,020 accessesView PDFCite
Research ArticleOpen accessIn the abstractEpidemiological Models Applied to Viruses in Computer NetworksJos R.S. Piqueira, Betyna F. Navarro, Luiz H.A. MonteiroTo investigate the use of classical epidemiological models for studying computer virus propagation we described analogies between computer and population disease propagation using SIR (Susceptible-Infected-Removed) epidemiological models. By modifying these models with the introduction of anti-viral individuals we analyzed the stability of the disease free equilibrium points. Consequently, the basal virus reproduction rate gives some theoretical hints about how to … …Journal of Computer Science, Vol. 1, Issue 1 · 31 Mar 2005 · 7,574 accessesView PDFCite
Research ArticleOpen accessIn the abstractDietary supplementation with Cyperus esculentus L (tiger nut) tubers attenuated atherosclerotic lesion in apolipoprotein E knockout mouse associated with inhibition of inflammatory cell responsesMohamed L. Salem, Mohsen Zommara, K. ImaizumiAtherosclerosis is a pathological process, where recruitment of mononuclear cells results in the growth of fibro-fatty plaques. Apolipoprotein E (ApoE) is a legend for the uptake of lipoproteins, and deficiency of ApoE leads to the accumulation of low-density lipoprotein. Utilizing ApoE-/- mouse, which spontaneously develop atherosclerosis on low-fat chow diets, the present study showed that feeding these mice on a … …American Journal of Immunology, Vol. 1, Issue 1 · 31 Mar 2005 · 10,471 accessesView PDFCite
Research ArticleOpen accessIn the abstractStrong Dependence at the Long Run and the Cyclical Frequencies in the Specification of the US Unemployment RateL. A. Gil-AlanaThis study deals with the presence of long range dependence at the long run and the cyclical frequencies in the specification of the US unemployment rate. We use a parametric procedure that permits us to test unit and fractional roots in raw time series. The results show that both the long run and the cyclical structures present a component of … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,501 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Situation and Evaluation of Forest Harvesting Methods in TurkeyMurat Demir, Tolga OzturkThe present study summarize and evaluate major problems of timber harvesting in Turkey and the future principles and objectives have been defined. Timber harvesting in Turkey is still carried out by manual methods due to economical, social and environmental constraints. Almost 80% of harvesting activities are mechanized in many developed countries while this value is only 5% in Turkey. Overall … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 7,396 accessesView PDFCite
Research ArticleOpen accessIn the abstractSocial-economic and Ecological Criteria of Noise ControlM. A. Al-NawaflehWhen designing new and/or modifying pre-existing equipment, the problem of economic feasibility is always of prime importance . However, the economic feasibility is often a matter of discussion in various social aspect. To operate no aesthetic, noisy, dusty, gazed heavy machine with large number of visually fixed moving parts and gearing, it is often dangerous and even risky. The work … …American Journal of Applied Sciences, Vol. 2, Issue 2 · 28 Feb 2005 · 6,676 accessesView PDFCite
Research ArticleOpen accessIn the abstractDevelopment of Ecological Criteria of Noise Control With Application of AbsorbentsM. A. Al-NawaflehThe operation conditions of the industrial equipment, acoustic parameters essentially depend on type of the sound field (free, diffuse or mixed). Besides the effect of the noise control of the machine itself, the field type also important, which in turn depends on the degree and quality of acoustic preparation of the workshop. The criteria is an estimation of applicability broadband … …American Journal of Applied Sciences, Vol. 2, Issue 1 · 31 Jan 2005 · 6,805 accessesView PDFCite
