Research ArticleOpen accessIn the abstractImpact of Design Principles and Patterns on Software Flexibility: An Experimental Evaluation Using Flexible Point (FXP)Muhammad Ehsan Rana, Eddy KhonicaSoftware flexibility is a crucial factor in designing and developing software as it reflects its capability to adapt to changes. It is a topic that has been discussed for a very long time which indicates its importance in software development. However, it is not easy to produce a flexible software design. Design principles provide fundamental concepts in designing good software. … …Journal of Computer Science, Vol. 17, Issue 7 · 31 Jul 2021 · 8,485 accessesView PDFCite
Research ArticleOpen accessIn the abstractLand-Cover Removal and Gully Development in Southeast Nigeria: A 30-Year Analysis with Pixel and OBIA Approaches in JuxtapositionSylvanus IroIn this study a study of gully erosion in southeast Nigeria is presented. The study of gully development on a regional scale is currently undermined by the inherent costs associated with consistent field monitoring and the lack of historic measurements to perform time series analysis. As a result, there are very few studies which implement long term analyses of gullies … …American Journal of Environmental Sciences, Vol. 16, Issue 2 · 9 Jun 2020 · 7,389 accessesView PDFCite
Research ArticleOpen accessIn the abstractPersonal Exposure to PM2.5 in the Various Microenvironments as a Traveler in the Southeast Asian CountriesSemih Ozler, Karoline K. Johnson, Michael H. Bergin, James Jay SchauerAir pollution has become a pressing issue in today’s society because of its significant effects on humans, animals, plants, air quality, climate and the wider environment. Most urban areas are associated with one or more air pollutants which are emitted from local or regional pollution sources including vehicle exhausts, fossil fuels using in energy production, emissions from industrial and mining … …American Journal of Environmental Sciences, Vol. 14, Issue 4 · 27 Oct 2018 · 9,277 accessesView PDFCite
Research ArticleOpen accessIn the abstractSequence Analysis of VP2 Gene of the Parvoviruses Isolated from Fecal Samples of Domestic Cats in Tehran, IranNegin Jahanbin, Shahram Jamshidi, Omid MadadgarPanleukopenia is a viral enteritis of high mortality rate in Feline population. It is caused by a small single-stranded DNA virus, belonging to the Family Parvoviridae, called Feline Panleukopenia Virus (FPV). Parvoviruses are capable of adapting to new hosts and can simply mutate like RNA viruses, resulting in the emergence of different strains with antigenic changes. Unlike the original Canine … …American Journal of Animal and Veterinary Sciences, Vol. 12, Issue 4 · 28 Oct 2017 · 7,696 accessesView PDFCite
Research ArticleOpen accessIn the abstractMetabolic Features of Heart Failure with Different EtiologyOleynikov Dmitrij ArkadievichDilated Cardiomyopathy (DCM) and Chronical Degenerative Valvular Disease (CDVD) are very common in dogs nowadays. However, due to modern level in oncology we can meet chemotherapy-induced cardiomyopathies more often. We have lack of information about pathogenic mechanisms underlying Doxorubicin-induced Cardiomyopathy (DoxCM) and features differentiating it from CDVD and DCM. In this study we investigate several metabolic features of doxorubicin-induced cardiomyopathy, … …American Journal of Animal and Veterinary Sciences, Vol. 12, Issue 1 · 9 Mar 2017 · 7,176 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Genomics of Domesticated and Wild Sunflower: Complete Chloroplast and Mitochondrial GenomesM. S. Makarenko, A. V. Usatov, N. V. Markin et al.The entire chloroplast and mitochondrial genomes of domesticated and wild type sunflower were sequenced. The comparative analysis of chloroplast genomes revealed 43 variant sites, including 21 polymorphic SSR loci and 22 SNPs. About 14 variant sites were found by collation of mitochondrial DNA (mtDNA), among them 4 SSRs, 8 SNPs and 2 deletions. About 9 SNPs were located in coding … …OnLine Journal of Biological Sciences, Vol. 16, Issue 1 · 29 Feb 2016 · 7,778 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Q-Routing Protocol Using Self-Aware Approach for Mobile Ad hoc NetworksAmal Alharbi, Abdullah Al-Dhalaan, Miznah Al-RodhaanMobile Ad hoc Networks (MANET) are self-organized networks that are characterized by dynamic topologies in time and space. This creates an instable environment, where classical routing approaches cannot achieve high performance. Thus, adaptive routing is necessary to handle the challenges in MANETs. Furthermore, it is necessary for nodes to be self-aware i.e., able to discover neighbors, links and paths when … …American Journal of Applied Sciences, Vol. 12, Issue 12 · 7 Dec 2015 · 6,468 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructural Dynamics of the Distribution Mechanism with Rocking Tappet with RollFlorian Ion T. Petrescu, John Kaiser Calautit, Dragan MarinkovicIn this study, the authors present a new method to dynamically synthesize a mechanism with rotary cam and rotated tappet with roll, used with priority at the distribution mechanisms from the heat engines with internal combustion. This type of distribution can improve the changes of gases and may decrease significantly the level of vibration, noises and emissions. As long as … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 28 Oct 2015 · 9,294 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeometrical Synthesis of the Distribution MechanismsFlorian Ion T. PetrescuIn this study the author presents shortly some few original trigonometric methods to make the synthesis of some main distribution mechanisms. One presents four main modules of distribution mechanisms, with rotary cam and translated or rotated tappet plane or with roll, used with priority at the distribution mechanisms from the heat engines with internal combustion. These types of distribution mechanisms … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 13 Apr 2015 · 8,866 accessesView PDFCite
Research ArticleOpen accessIn the abstractChanges in the Rumen Papillae During the Periparturient Transition in Holstein Dairy Cows are Accompanied by Changes in Abundance of Proteins Involved in Intracellular pH Regulation, But not SCFA TransportAnne Hermen Laarman, Adam Kleinberg, Michael Alexander Steele et al.The objective of this study was to examine changes in SCFA transport capacity in the rumen epithelium during the parturition transition period. Twelve pregnant, cannulated primiparous and multiparous cows were fed a standard Total Mixed Ration (TMR) for the duration of the dry period; after calving, all cows were switched to an early lactation TMR. Rumen pH, fluid and biopsies … …American Journal of Animal and Veterinary Sciences, Vol. 10, Issue 1 · 31 Mar 2015 · 7,554 accessesView PDFCite
