Research ArticleOpen accessEvery word in the titleDamage Pattern and Nesting Characteristic of Coptotermes curvignathus (Isoptera: Rhinotermitidae) in Oil Palm on PeatWei-Hong Lau, Choon-Fah J. Bong, Seow-Phan ChanThe oil palm industry of Malaysia has expanded into peat area in Sarawak. Problem statement: The subterranean termite Coptotermes curvignathus was a serious pest of oil palm on peat. Control of this termite has resorted to heavy usage of chemicals which was deemed uneconomical and hostile to the environment. Baiting system has inconsistent success due to the limited knowledge of … …American Journal of Applied Sciences, Vol. 8, Issue 5 · 17 May 2011 · 8,657 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIntegrity Classification Algorithm of Images obtained from Impact Damaged Composite StructuresMahmoud Z. IskandaraniProblem statement: Many NDT systems used for damage detection in composites are difficult to apply to complex geometric structures, also, they are time-consuming. As a solution to the problems associated with NDT applications, an intelligent analysis system that supports a portable testing environment, which allowed various types of inputs and provided sufficient data regarding level of damage in a tested … …Journal of Computer Science, Vol. 6, Issue 4 · 30 Apr 2010 · 6,970 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Assessment of Compressive Size Effect of Plane Concrete Using Combination of Micro-Plane Damage Based Model and 3D Finite Elements ApproachM. Labibzadeh, S. A. Sadrnejad, M. NaisipourIn recent years, the material behavior dependence of laboratory concrete specimens built with the same concrete mixture under the same load conditions to their geometrical sizes is well established. This phenomenon which is observed not only in concrete but also in most quasi-brittle materials such as rock, ceramic or composite materials is now called as size effect. Many of the … …American Journal of Applied Sciences, Vol. 5, Issue 2 · 28 Feb 2008 · 7,005 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCrack Analysis of Concrete Arch Dams Using Micro-Planes Damage Based Constitutive RelationsM. Labibzadeh, S.A. SadrnejadAmong the various numerical simulating models of plane concrete, the micro-planes models have an excellent position. These models are not as complicated as microscopic models such as discrete particles models and do not have the shortcomings of macroscopic models based on the stress or strain invariants. The object of this study is the application of author's recently developed micro-planes damage … …American Journal of Applied Sciences, Vol. 4, Issue 4 · 30 Apr 2007 · 6,978 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMesoscopic Damage Based Model for Plane Concrete under Static and Dynamic LoadingsM. Labibzadeh, S. A. SadrnejadThe constitutive equations for the mechanical behavior of concrete capable of seeing damage effects or crack growth procedure under loading/unloading/reloading was developed upon microplane framework. The proposed damage formulation has been built on the basis of five fundamental types of stress/strain combinations, which essentially may occur on any of microplanes. Model verification under different loading/unloading/reloading stress/strain paths has been examined. … …American Journal of Applied Sciences, Vol. 3, Issue 9 · 30 Sep 2006 · 8,044 accessesView PDFCite

Askari Asli-Ardeh, Y. Abbaspour-GilandehProblem Statement: Regarding to considerable production of rice crop in Iran, study and investigation about optimization of different stages of this product processing seems necessary. The threshing of rice is a process which must be accomplished desirability. Approach: In this study, the effective factors effects on threshing loss, damaged grain percent and Material Other than Grain (MOG) to grain ratio, … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 7,911 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFerulic Acid in Chinese Herbal Medicine: Regulating Autophagy for Oxidative Damage ReductionZhiyuan Lv, Qiaozhen Zhao, Shanbin Chen et al.Ferulic Acid (FA) is the primary functional component in herbal plants and traditional fermented foods. To comprehend the mechanism of action of ferulic acid, in terms of its regulation of autophagy, antioxidants and the inhibition of inflammatory pathways, the study was conducted. Oxidatively damaged human-derived hepatocytes were treated with FA and the processing concentration of FA is from 50-800 μm. … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 2 · 1 Jun 2024 · 5,483 accessesView PDFCite
