Research ArticleOpen accessIn the abstractBehavior of Stabilized Peat Soils in Unconfined Compression TestsWong Leong Sing, Roslan Hashim, Faisal Haji AliProblem statement: Deep stabilized peat columns were known to be economical at forming foundations to support highway embankments constructed on deep peat land. However, failure in the formation of the columns with adequate strength was often attributed to unsuitable type and insufficient dosage of binder added to the soil. Organic matter in peat was known to impede the cementing process … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2008 · 7,459 accessesView PDFCite
Research ArticleOpen accessIn the abstractValorization of Drinking Water Treatment Sludges as Raw Materials to Produce Concrete and MortarR.M. Ramirez Zamora, O. Ceron Alfaro, N. Cabirol et al.The purpose of this work was to assess the technical feasibility to valorize sludges, generated and stored at the Los Berros drinking water facility (PPLB), as raw material to produce building products (mortar and concrete) for the construction industry. The experimental study was divided into three stages: 1) sampling and characterization of PPLB sludges to determine their potential as raw … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 7,583 accessesView PDFCite
Research ArticleOpen accessIn the abstractCompressive Load Resistance Characteristics of Rice GrainSumpun Chaitep, Chaiy Rungsiyakull, Pipatpong WatanawanyooInvestigation was made to observe the compressive load property of rice gain both rough rice and brown grain. Six rice varieties (indica and japonica) were examined with the moisture content at 10-12%. Compressive loads with reference to a principal axis normal to the thickness of the grain were conducted at selected inclined angles of 0°, 15°, 30°, 45°, 60° and … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 8,184 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Performance of EPS Footing for Lightweight Farm Structure on Peat SoilMohammad Abdullah, Bujang B.K. Huat, Rezuwan Kamaruddin et al.The objective of this research project was to find a potential replacement for the conventional pile foundation principally for peat soil. It is fundamentally meant for lightweight and impermanent agricultural farm structures. Preceding the design and development of the foundation the physical characteristics of the in-situ peat such as; peat depth, soil consolidation, soil compressibility, water table, liquid limit, soil … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,244 accessesView PDFCite
Research ArticleOpen accessIn the abstractSustainable Technology for Agriculture at Extreme Altitudes: Design and Evaluation of a Sprinkler Irrigation System in a Peruvian High Andean CommunityJuan Eduardo Suarez Rivadeneira, Freddy A. Manayay, Daniel Olivier Carranza Lizana et al.In high-altitude agroecosystems, erratic rainfall patterns and steep topography severely constrain crop productivity by exposing plants to soil water deficits during critical phenological stages. This study aimed to enhance the productivity of eleven staple and horticultural crops corn (Zea mays), tomato (Solanum lycopersicum), cucumber (Cucumis sativus), eggplant (Solanum melongena), lettuce (Lactuca sativa), carrot (Daucus carota), barley (Hordeum vulgare), celery (Apium … …OnLine Journal of Biological Sciences, Vol. 26, Issue 4 · 2 Oct 2026 · 663 accessesView PDFCite
Research ArticleOpen accessIn the abstractFlavonoids and Antimicrobial Properties of Begonia fischeri var. palustris in vitro PlantletsEvgeniya A. Karpova, Alexandra Yu. Nabieva, Tatiana D. Fershalova et al.The objective of this study was to design a protocol of the successful establishment of plants of Begonia fischeri var. palustris obtained in the in vitro seeds culture, to evaluate flavonoid content and antimicrobial properties of in vitro plantlets. The significant increase of percentage of seed germination (92.5%) was recorded in the half strength MS medium and 1% agar medium … …OnLine Journal of Biological Sciences, Vol. 19, Issue 1 · 29 Jan 2019 · 7,652 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of A Microwave Amplifier for Wireless ApplicationM. Habib Ullah, Badariah Bais, Norbahiah Misran et al.Problem statement: Low-Noise Amplifiers (LNA) are very indispensable components in the design of numerous types of communication receivers employed in microwave technology. This paper is presents the design and development of low bias(Vce = 8v, Ic =10 mA) single stage low noise microwave amplifier operating in 1.5GHZ frequency range, Gain 13dB ± 0.5dB, input/output return loss < -10dB, noise figure … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 3 Nov 2011 · 8,231 accessesView PDFCite
Research ArticleOpen accessIn the abstractNumerical Analysis of Lattice Structures for Skin Layer in Camber Morphing WingBashir Alsaidi, Woong Yeol Joe, Muhammad AkbarUnlike conventional fixed wings and their static skin structure considering only expected aerodynamic loadings while filight, design strategies of skin structure for morphing wings require careful consideration of structural loading from shape changes and aerodynamics and their coupled effects in flight. Many morphing wings often overlook skin material and structure for the wing design. In addition to that, many works … …American Journal of Applied Sciences, Vol. 16, Issue 6 · 15 Jul 2019 · 7,742 accessesView PDFCite
Research ArticleOpen accessIn the abstractTechnical Buckling, Stress and Strain Simplified Analysis of Semi-Slender Thin-Walled Cylindrical Pinned ColumnKrzysztof MurawskiThe stability of load-bearing members is a challenging issue for designers. The avoidance of possible stability troubles is a mandatory step of the overall design process. The paper presents and discusses two simplified methods based on the Technical Stability Theory (TSTh) of loss of stability of lateral buckling in elastic-plastic states of semi-slender columns axially compressed by force. It is … …International Journal of Structural Glass and Advanced Materials Research, Vol. 5, Issue 1 · 27 May 2021 · 6,827 accessesView PDFCite
Research ArticleOpen accessIn the abstractVulnerability and Protection of Glass Windows and Facades under Blast: Experiments, Methods and Current TrendsXihong Zhang, Chiara BedonGlass has been overwhelmingly used for windows and facades for modern constructions. Nevertheless, due to its relatively low tensile strength and mostly brittle behaviour, compared to other structural members, glass windows/facades are one of the most fragile components for a building envelop that are always associated with vast casualties in a blast incident. Several researches have been carried out to … …International Journal of Structural Glass and Advanced Materials Research, Vol. 1, Issue 2 · 24 Jul 2017 · 14,167 accessesView PDFCite
