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 titleTrace Elements in Fertilizers Used in PeruVíctor Gómez, Mauricio Molina-Roco, Elder Chichipe, Eli Morales RojasFertilizers provide essential nutrients for crops, however, they may also inadvertently provide trace elements that in certain concentrations represent a risk to the soil and the food chain. The objective of this research was to determine the concentrations of Cd, Pb, Cu, and Zn in the most common fertilizers used in Peruvian agriculture. Twenty-one products including inorganic, organic mineral, and … …OnLine Journal of Biological Sciences, Vol. 23, Issue 2 · 10 Apr 2023 · 6,440 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleBasis of Guidelines for Structural Design and Thermal Assessment of Buildings with Hybrid CLT-Glass ElementsNikola Perković, Vlatka Rajčić, Chiara Bedon et al.Facade elements are known to represent a building component with multiple performance parameters to satisfy. Among others, “advanced facades” take advantage from hybrid solutions, like the assemblage of laminated materials. In addition to enhanced mechanical properties that are typical of optimally composed hybrid structural components, these systems are energy efficient, durable and offer lightening comfort and optimal thermal performance. This … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 9 Apr 2020 · 6,969 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAssessment of the Elements of the Sudan Grass Cultivation Technology in the Zone of Dry SteppesBeybit Nasiyev, Nurbolat Zhanatalapov, Vladimir ShibaikinSudan grass (Sorghum Sudanese (Piper.) Stapf) is the most productive, drought-resistant and promising crop for the dry-steppe zone of Western Kazakhstan. In this regard, in order to ensure an uninterrupted supply of livestock with feed raw materials, studies devoted to improving the elements of the Sudan grass cultivation technology in the conditions of the region are relevant. During the studies, … …OnLine Journal of Biological Sciences, Vol. 21, Issue 1 · 26 Mar 2021 · 6,679 accessesView PDFCite

Research ArticleOpen accessEvery word in the titlePresentation of Four-stroke Engine Design ElementsRelly Victoria Virgil PetrescuHaving escaped the shadow of the global energy crisis by implementing nuclear fission, wind, solar, bioenergy, but also by producing and extracting (deep) gases capable of providing us with planetary reserves for two more. Or at least three thousand years, we have started to relax more energetically, but due to the huge pollution produced by cars, the rules of their … …Journal of Mechatronics and Robotics, Vol. 4, Issue 1 · 28 Apr 2020 · 6,950 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGamification in E-Learning: Introducing Gamified Design Elements into E-Learning SystemsDaniel Strmečki, Andrija Bernik, Danijel RadoševićGamification is the usage of game mechanics, dynamics, aesthetics and game thinking in non-game systems. Its main objective is to increase user’s motivation, experience and engagement. For the same reason, it has started to penetrate in e-learning systems. However, when using gamified design elements in e-learning, we must consider various types of learners. In the phases of analysis and design … …Journal of Computer Science, Vol. 11, Issue 12 · 11 Feb 2016 · 11,336 accessesView PDFCite
