Research ArticleOpen accessEvery word in the titleUltrasonographic Apperance of the Gestational Structures Throughout Pregnancy in BitchesA. Aissi, C. SlimaniUltrasonographic examinations of 10 pregnant bitches with known breeding dates were made on successive days to establish the identifiable characteristics of pregnancy. Subsequent serial examinations were made to sonographically characterize normal canine prenatal development based about the first mating. The initial detection of the fetal and extra-fetal structures were as follows: gestational sac at day 17.88±1.13 (16-21); zonary placenta in … …American Journal of Animal and Veterinary Sciences, Vol. 3, Issue 1 · 31 Mar 2008 · 7,222 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleProtein Molecular Structures, Protein SubFractions, and Protein Availability Affected by Heat Processing: A ReviewPeiqiang YuThe utilization and availability of protein depended on the types of protein and their specific susceptibility to enzymatic hydrolysis (inhibitory activities) in the gastrointestine and was highly associated with protein molecular structures. Studying internal protein structure and protein subfraction profiles leaded to an understanding of the components that make up a whole protein. An understanding of the molecular structure of … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 8,286 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDefect Classification of Reinforced Concrete Structures with Nondestructive Tests Using Statistical and Machine Learning MethodsSajjad Sayyar-Roudsari, Armaghan Shalbaftabar, Farshid Damirchilo et al.In this study, twelve reinforced concrete beams were constructed, each with specified dimensions and initial compressive strength. The beams were divided into four groups: A control group without any defect, a void group featuring a centrally located void, a corrosion group and a debonding group. The impact echo test was used for nondestructive testing, gathering data on compressive and shear … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 3 · 11 Jun 2024 · 5,258 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBuilding Design Rule for Glass Structures by Persian CurveAbdolrasoul Ranjbaran, Mohammad Ranjbaran, Fatema RanjbaranGlass is being increasingly used as a structural material. Its favorable aesthetic qualities have made it popular with modern designers. Recently glass is used for major structural elements such as beams and columns in modern and innovative architectural applications. High slenderness ratios and brittle behavior in tension contribute to the complexity of stability and ultimate strength analysis of glass structures. … …International Journal of Structural Glass and Advanced Materials Research, Vol. 5, Issue 1 · 16 Jan 2021 · 8,408 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Watershed Structures in Controlling Runoff - Case Study of Sardasht Basin in IRANSeyedeh Zahra Hosseini-Teshnizi, Ghodratollah Davoudi, Seyedeh Laleh Razavi, Kaveh Ostad-Ali-AskariIn order to investigate the performance of constructed structures in Sardasht watershed, Soil and Water Assessment Tools model for simulation of runoff and sediment during the studied period of 1996-2012 was carried out for two cases of existence and absence of flood control structures. From 2007 onwards by performing watershed operations in these sub-basins, the average runoff rate decreased about … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 1 · 26 Feb 2020 · 7,346 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSmall-Scale Test of Transparent Adhesives in Glass Structures under Shear Stress and Their Ageing ResistanceMarkéta Zikmundová, Martina EliášováGlass load-bearing structures, which have been popular in recent years, require careful attention to detail, because with improper design there is a concentration of stress leading to failure and subsequent collapse of the structure. Mechanical connections are mainly used but there are disadvantages such as stress peaks, weakening of the cross-section, or aesthetic reasons. Adhesive connections eliminate these disadvantages. The … …International Journal of Structural Glass and Advanced Materials Research, Vol. 6, Issue 1 · 6 Mar 2022 · 6,561 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNumerical 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 · 7,740 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleEducational Challenges in Computer-based Finite Element Analysis and Design of StructuresVagelis Plevris, Gro MarkesetComputer simulations and computational methods, such as the Finite Element Analysis (FEA) have become essential methodologies in science and engineering during the last decades, in a wide variety of academic fields. Six decades after the invention of the digital computer, advanced FE simulations are used to enhance and leapfrog theoretical and experimental progress, at different levels of complexity. Particularly in … …Journal of Computer Science, Vol. 14, Issue 10 · 26 Oct 2018 · 8,625 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNondestructive Test Using a 3D Computer Vision System for Damage Detection of StructuresTaylor M.V. Szeto, Sun YiStructures that do not have a definitive map nor a clearly known state of health may exist underground, beyond our reach and in unsuitable environments. Nuclear facilities contain underground tunnels that exhaust hazardous gases. Industry has miles of sewage lines beneath it that emit flammable and toxic gases. Regular inspection and maintenance is an essential part of failure prevention, however, … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 2 Jun 2018 · 8,257 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleOffshore Geotechnical Problems in Deepwater Mooring Techniques for Large Floating StructuresHaixiao Liu, Zhou Li, Yuming ZhangAn effective, reliable and economic positioning technique is of great necessity for offshore large floating structures. Within all techniques of station keeping, mooring plays a vital role for large floating structures. Clear knowledge of the role and particularities of mooring systems is important to the design, operation and analysis of large floating structures especially in deep waters.
