Research ArticleOpen accessIn the keywordsPrevalence of Depression among High School Students and its Relation to Family StructureAli Daryanavard, Abdoulhossain Madani, Mohammad Saeid Mahmoodi et al.Problem statement: Depression is common in adolescents and especially in high school students. The aim of this study was to determine the prevalence of depression among high school students and its relation to parental configurations. Approach: A cross-sectional study was conducted during first term of the academic year 2003-2004. Data was collected by Beck Depression Inventory questionnaire (BDI-21 test) and … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 9,231 accessesView PDFCite
Research ArticleOpen accessIn the abstractSmall-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 accessIn the abstractReduction of Radiation Effects in Biomedical Imaging Detectors by Technology ChangeEssesse Songa Auguste, Wembe Tafo Evariste, Madinatou Salomon, Belinga Aboudou JeanSilicon is a preferred material in the design of medical imaging detectors. It enables reliable and inexpensive detectors to be produced. However, the operation of this material is compromised when irradiated with high radiation of more than 5 ×1014 particles/cm2of high energy neutrons. The defects caused transform the electrical properties. Therefore, this loss of information compromises the reconstruction of important … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 3 · 17 Jul 2021 · 6,987 accessesView PDFCite
Research ArticleOpen accessIn the abstractParametric Study to Maximize the Useful Life of Reinforced Concrete ColumnsTamires L. Mezzomo, Moacir KripkaThe current scenario of structural engineering is guided by the growing ecological concern and constant search for efficient and economic structural solutions. In this sense, aspects related to the durability of structures have become a significant topic of study. Based on this context, the purpose of this work was to provide resources that allow the maximization of the useful life … …International Journal of Structural Glass and Advanced Materials Research, Vol. 5, Issue 1 · 8 Jun 2021 · 6,543 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 · 6,823 accessesView PDFCite
Research ArticleOpen accessIn the abstractStability, Stress and Strain Analysis of Very Slender Pinned Thin-Walled Box Columns according to FEM, Euler and TSThKrzysztof Murawski, Alexandre de Macêdo WahrhaftigIn this study, a Finite Element Method (FEM) analysis is presented for the loss of stability in elastic states of very slender pinned without friction box-section thin-walled column axially compressed. From the FEM buckling linear stress analyses are determined the compressing critical forces for 36 cases, presented in tables and as the surface functions in dependence on the slenderness ratio … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 2 · 11 May 2021 · 7,192 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Comparison of the Known Hypotheses of the Lateral Buckling for Semi-Slender Pinned ColumnsKrzysztof MurawskiThe paper presents the comparison of experimental results obtained from tests on semi-slender columns with pinned ends made of steel R35 to simplifications and hypotheses of loss of stability by lateral buckling in elastic-plastic states of columns axially compressed by force. The Tetmajer-Jasiński’s and Johnson-Ostenfeld’s simplifications, as well as the hypotheses given by Engesser and Kármán and Shanley, Ylinen, Březina, … …International Journal of Structural Glass and Advanced Materials Research, Vol. 5, Issue 1 · 14 Apr 2021 · 6,411 accessesView PDFCite
Research ArticleOpen accessIn the abstractInnovations in Access to Justice in Uganda: Justice Users’ LensKakuru Timothy, Ssendikaddiwa Emmanuel, Kennedy Kasozi et al.Access to justice remains a global challenge and in Uganda, four in ten people have at least one legal problem every four years, yet seven in ten of the legal problems are not resolved. While innovation is critical to changing the status quo, most innovations have been mostly informed by what legislators and legal practitioners need to do their jobs … …Journal of Social Sciences, Vol. 20, Issue 1 · 29 Jul 2024 · 6,735 accessesView PDFCite
Research ArticleOpen accessIn the abstractTechnical Stability of Very Slender Rectangular Columns Compressed by Ball-And-Socket Joints without FrictionKrzysztof MurawskiStability of load-bearing members, as known, is a challenging issue and several tools are available for designers. Disregarding the material properties in use, the avoidance of possible stability troubles is a mandatory and challenging step of the overall design process. In this study, a theoretical model is presented for the of loss of stability in elastic states of very slender … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 16 Nov 2020 · 5,995 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Investigation on the Failure Mechanism of Bovine Bone by Three-point Bending TestsHua Li, Rujie Gao, Ruiqi Li et al.Bone damage is a common type of sport injury. The loading rate affects the type of fracture and the degree of soft tissue injury. In view of the problem of whole bone bending damage and failure, this paper introduces the test method of bovine bone bending and the mechanism of bending failure under different loading rates is analyzed through experimental … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 3 · 10 Jul 2020 · 6,535 accessesView PDFCite
