Research ArticleOpen accessEvery word in the titleA Methodology for the Selection of Micro-Assembly TechniquesDario Antonelli, Gualtiero Fantoni, Marcello Porta, Marco SantochiProblem statement: The study addressed the problem of selecting the appropriate microassembly techniques according to the micro-part features. Actually, in the micro-domain, the choice of the correct assembly technique is highly dependent on the micro-part characteristics such as shape, geometry and material. Approach: Since there was an incomplete and unstructured knowledge about the micro-assembly, the study proposed a Decision Support … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 8,184 accessesView PDFCite

Approach: The aim of this research was first, to achieve the best mix design of light weight concrete which could be in light weight concrete category and second, by applying the first part gain the main reason of this research which was finding the … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 7,626 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMechanism of Microencapsulation with Urea-Formaldehyde PolymerRochmadi, Agus Prasetya, Wahyu HasokowatiProblem statement: Microcapsule is one of important fine chemical products in the current chemical industries. Better understanding of microencapsulation process is useful to properly design of microcapsule with specific characteristics. The aim of this research is to study the mechanism of Urea-Formaldehyde (UF) microcapsules formation. Approach: Microcapsule was prepared in two steps. The first step was the preparation of oil … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 8,718 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleWomen Empowerment through Participation in Micro-Credit Programme: A Case Study from BangladeshMahmuda Hoque, Yoshihito ItoharaProblem statement: Numerous micro-credit organizations have been emerged as the form of mushroom in Bangladesh in the recent times. All of them are providing micro-credit to the poor women with the view of poverty reduction and empowering the rural women. Thus, the researchers take an attempt to check that to what extent these micro-credit programmes are effective in empowering rural … …Journal of Social Sciences, Vol. 5, Issue 3 · 30 Sep 2009 · 9,043 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 · 7,007 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 · 6,983 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBiological Activity of Methyl tert-butyl Ether in Relation to Soil Microorganisms has a Negative Environmental ImpactGholam H.S. BonjarFuel oxygenates are added to gasoline to enhance combustion efficiency of automobiles and reduce air pollution. Methyl tert-butyl ether (MTBE) is the most commonly used oxygenate because of its low cost, high-octane level and ease of blending with gasoline. However, due to its water solubility, high mobility and low biodegradability it leaches in soil subsurface at the speed of groundwater. … …American Journal of Environmental Sciences, Vol. 1, Issue 2 · 30 Jun 2005 · 6,665 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleExpression of Exosome-Derived MicroRNAs miR-21 and miR-135 are Differentially Regulated Among Dental Pulp Stem CellsMatthew Hunsaker, Brandon Richards, Adelle Fuller et al.Dental Pulp Stem Cells (DPSCs) are a type of mesenchymal stem cell that has the potential to differentiate into various types of cells and tissue. Previous research has demonstrated that DPSCs can be easily accessed and isolated from both permanent and deciduous teeth, such as wisdom teeth or third molars, although there is less information available about the mechanisms and … …Current Research in Medicine, Vol. 11, Issue 1 · 10 Jan 2023 · 10,541 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleImpact of Ultra Violet Radiation on Polyethylene Packaged Water Exposed at Varying Conditions: Are we Drinking Micro-Plastics?James Matthew Anayo, Victor Eshu Okpashi, Ikechukwu N.E. OnwurahThe public is worried about how their health is impacted by microplastics in sachet water. This awareness has repercussion for water producing factories and public health organization in managing health hazard associated with microplastic ingestion. Many countries in Africa, with concern to Nigeria, the act of packaging water in polyethylene materials by water producing factories has become accustomed. These packaged … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 1 · 29 Jan 2018 · 9,918 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffects of Maize Potato Intercropping and Different Fertilization Methods on Rhizosphere Soil Microorganisms and Yield of PotatoHuanjin Ma, Shengguang Xu et al.A field experiment with three replicates was conducted to explore the effects of maize-potato intercropping and different nitrogen application strategies on rhizosphere soil microorganisms and potato yield. Microbial community analysis was based on relative abundance. Maize-potato intercropping improves land use efficiency, yet how differentiated nitrogen management regulates rhizosphere microecology and potato productivity in this system remains unclear. Clarifying nitrogen-mediated shifts … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 14 Sep 2026 · 814 accessesView PDFCite
