Research ArticleOpen accessIn the abstractReliability Assessment of Buckling Strength for Compressed Cylindrical Shells with Interacting Localized Geometric ImperfectionsJalal El Bahaoui, Abdellatif Khamlichi, Larbi El Bakkali, Ali LimamProblem statement: Elastic cylindrical shells are common structures in the fields of civil engineering and engineering mechanics. These thin-walled constructions may undergo buckling when subjected to axial compression. Buckling limits to large extent their strength performance. This phenomenon depends hugely on the initial distributed or localized geometric imperfections that are present on the shell structure. Localized geometric imperfections result in … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 4 Nov 2010 · 8,320 accessesView PDF Cite

Research ArticleOpen accessIn the abstractComplexity in Human Perception of Brightness: A Historical Review on the Evolution of the Philosophy of Visual PerceptionKuntal Ghosh, Kamales BhaumikProblem statement: The “eye-brain” complex, which contributes maximally to visual perception, is no doubt a very interesting object for complexity study. In this review we shall try to present some of its aspects in perceiving brightness. It is a well-known fact that the perceived brightness of any surface depends on the brightness of the surfaces that surround it, a phenomenon … …OnLine Journal of Biological Sciences, Vol. 10, Issue 1 · 30 Jun 2010 · 8,680 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Tumor/Immune Interface: Clinical Evidence of Cancer Immunosurveillance, Immunoediting and ImmunosubversionMatthew S. Block, Svetomir N. MarkovicProblem statement: The interactions of a malignant tumor with the patient’s immune system are dynamic, multiple and bi-directional. Approach: This article reviews the clinical evidence of the interaction of cancer with immunity with emphasis on recent developments highlighting some of the mechanisms of tumor-mediated regulation of immunity. Results: Most of the time, the immune response to a malignancy acts to … …American Journal of Immunology, Vol. 5, Issue 1 · 31 Mar 2009 · 10,095 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Study of the Effect of Infilled Brick Walls on Behavior of Eccentrically Braced Frames Using Explicit Finite Elements MethodAmir Saedi Daryan, Masood Ziaei, Ali Golafshar et al.Problem statement: Eccentrically Braced Frames (EBFs) are usually infilled by masonry walls, but in common design, the stiffness and lateral resistance of these walls is ignored. Considering the results of carried out tests and studies, it seems that infilled masonry walls have a significant influence on the stiffness and the strength of EBFs. Since experimental test of total frame with … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 1 · 31 Mar 2009 · 8,191 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Combining Ability Analysis of Cassava Manihot esculenta Crantz Genotypes to Anthracnose DiseaseO. F. Owolade, A. G.O. Dixon, S. R. Akande, S. A. OlakojoCassava Anthracnose Disease (CAD) caused by Colletotrichum gloeosporioides f sp. manihotis has been recognized as one of the major economic disease of cassava in all the cassava growing regions of Africa. Little information is available on the resistance of cassava to C. gloeosporioides f sp. manihotis. This study was conducted to determine the relative importance of general (GCA) and specific … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,800 accessesView PDF Cite

Research ArticleOpen accessIn the abstractIdentification of Novel Chromosomal Abnormalities, inv(5)(p13q13) and t(7;18)(q32;q21), Associated with AutismZheng Chen, Xiao-bing Zou, Ya-nan Zhang et al.Autism is a neurodevelopmental disorder defined by impairments in social interaction, communication, as well as restricted and stereotyped behaviors. While the etiology of autism remains largely unknown, the existence of genetic components has been clearly demonstrated in autistic pathogenesis. The incidence of autism is 50-100 fold greater in the population with autistic family history than the general population. Chromosomal abnormalities … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 3 · 30 Sep 2007 · 6,773 accessesView PDF Cite

Research ArticleOpen accessIn the abstractInvestigation of Stomata Densities in Pea (Pisum sativum L.) Lines/CultivarsHatice Bozoglu, Reyhan KarayelThis study was conducted to determine, if stomata density can be used as a criterion in cultivar differentiation or not. In this study, density of stomatas in stipula and abaxial and adaxial surface of leaflets was determined in the flowering and pod set period of 23 pea cultivars and lines that were sowed as wintertime for 2 years. The effect … …OnLine Journal of Biological Sciences, Vol. 6, Issue 2 · 31 Dec 2006 · 6,947 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStudy of the Thermodynamic Equilibrium of Fragrance Mixtures, Limonene, Linalool and Geraniol, using the Unifac and Cosmo-Sac Models and the Estimation of their Combined Properties in Binary, Ternary and Quaternary MixturesLavínia Mota Cristianismo Silva, José Izaquiel Santos da Silva, Rogério Alexandre Alves de Melo, Edilailsa Januário de MeloPerfume is a non-ideal complex mixture of chemicals originating from the extraction of essential oils and these oils are volatile components extracted from plants, some animals, or even synthesized. For this reason, to compose a fragrance, there are countless possibilities to combine one element and another, which makes the process slow and expensive.

Research ArticleOpen accessIn the abstractNatural Reforestation Optimization (NRO): A Novel Optimization Algorithm Inspired by the Reforestation ProcessFernando L. Rodríguez-Gallegos, César A. Rodríguez-Gallegos, Andrés A. Rodríguez-Gallegos, Carlos D. Rodríguez-GallegosThis paper proposes a new meta-heuristic-based optimization algorithm for single-objective problems. The algorithm is called Natural Reforestation Optimization (NRO) and is inspired by the process in which natural reforestation takes place. The features of this algorithm (such as the distribution of the initial population, the exploration and exploitation mechanisms, the interactions between the particles, the stopping criteria, among others) are … …Journal of Computer Science, Vol. 16, Issue 8 · 2 Sep 2020 · 6,655 accessesView PDF Cite
