Research ArticleOpen accessIn the abstract2D Kinematic Quantification of Soil Particles around Growing Plant Root based on Optical MechanicsWenbin Wu, Jian ZhaoThe quantitative kinematic description of the surrounding soil particles during root growth is a technical challenge and biologically important. In this study, a two-dimensional camera-based imaging system was used to observe micro scale interactions between plant roots and soil particles. Maize root tip was imaged during ingress into the soils. This produced a series of two-dimensional images that represent temporal … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 21 Oct 2020 · 6,413 accessesView PDFCite
Research ArticleOpen accessIn the abstractFall Detection Using the Histogram of Oriented Gradients and Decision-Based FusionMohamed Maher Ben Ismail, Arwa AlGabas, Ouiem BchirAs the number of fall incidents among elderly people and patients are continuously growing, researches boosted their researches to propose efficient automatic fall detection systems. In particular, they formulated the fall detection problem as a supervised learning task where some visual features are extracted from the video frames and used to automatically identify the position of a human as “Fall” … …Journal of Computer Science, Vol. 16, Issue 2 · 26 Feb 2020 · 7,505 accessesView PDFCite
Research ArticleOpen accessIn the abstractFractal Dimension for the Characterization of Asphalt Mixture PropertiesGiovanni LeonardiIn the design of asphalt mixtures for paved roads, the shape of solid elements has a great importance. In asphalt concrete, the shape of aggregate particles influences the resistance, durability, stiffness, fatigue response and the required binder content of the mixture. Fractal geometry is more suitable to describe the irregularity of the shape of aggregate particles. This paper describes the … …American Journal of Applied Sciences, Vol. 13, Issue 7 · 13 Jul 2016 · 7,184 accessesView PDFCite
Research ArticleOpen accessIn the abstractSlow Fungal Hydrolysis of Complex Sugar is Responsible for the Use of Sugar as Vehicle for Antifungal DrugsNedosa Ikenna Valentine, Utoh-Nedosa Uchechukwu Anastasia, Dan Danjuma et al.Problem statement: Aspergillus niger strain (UUF 9202) significantly reduced the dormancy period and boosted aggregate germination time in seeds of Tetrapleura tetraptera by 42% in 32 days and produced a net reduction in mean germination time of the seeds to 12 days. A structure-fungitoxicity relationship study of a series of isoflavonoids against Aspergillus niger and Cladosporium cucumerinum showed that a … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 3 · 2 Nov 2011 · 7,666 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of the Transport Properties of Tyre Fiber Modified ConcreteG. Senthil Kumaran, M. Lakshmipathy, Nurdin MushuleProblem statement: Nowadays, the use of waste tyre in concrete has become technically feasible and the tyre mixed concrete is light weight and called as rubberized concrete. Still the research is going on to explore basic engineering properties such as transport properties viz, acid absorption test, water absorption tests, impact resistance, modulus of elasticity, dynamic modulus and so on. In … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 30 Sep 2011 · 7,438 accessesView PDFCite
Research ArticleOpen accessIn the abstractRational Mix Design Approach for High Strength Concrete Using Sand with very High Fineness ModulusKwan Wai Hoe, Mahyuddin RamliProblem statement: Production of concrete is always deal with inconsistency. Sources of variation like materials from different geographical basis, mix design method, fineness of aggregates and so on will attribute to different level of achievement of the concrete. Even though researcher had verified that higher fineness modulus of sand would yield better performance for the concrete, but so far there … …American Journal of Applied Sciences, Vol. 7, Issue 12 · 31 Dec 2010 · 8,222 accessesView PDFCite
