EditorialOpen accessIn the abstractProtecting crop species from biotic and abiotic constraints in the era of Global Change: are we ready for this challenge?Marco Landi, Giovanni BenelliReliable and affordable supply of food is of crucial importance to the progress and stability of human societies. During the last century, we have assisted to an extraordinary increase of crop yields, especially for the most widespread and consumed crop species, such as rice, wheat, corn and soybean. The Broadbalk experiment, one of the oldest continuous agronomic experiments in the … …American Journal of Agricultural and Biological Sciences, Vol. 11, Issue 2 · 4 Jun 2016 · 8,399 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Manifestation of the Discrete and Continuous Types of Bioelectric Control of Natural Locomotion at the Over-Five AgeKazbek Chermit, Anatoliy Zabolotniy, Angelina ShakhanovaThe concept of physiology of activity by N.A. Bernstein, developed on the grounds of in-depth theoretical and empirical analysis of natural human locomotion, served as a basis for understanding the target determination of human behavior, the mechanisms of motor skills formation and levels of building movements. Scientific and technological progress has determined the emergence of new methods for registration of … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 27 May 2016 · 7,098 accessesView PDFCite
Research ArticleOpen accessIn the abstractContrasting Effects of Metal Contaminations and Soil Liming on Cations Exchange Capacity and Global DNA Methylation in Betula papyrifera Populations from a Mining RegionGabriel Theriault, Kabwe NkongoloThe Greater Sudbury Region in Northern Ontario (Canada) has been one of the most contaminated regions in the world. Soil liming with dolomitic limestone applications has decreased significantly the level of soil acidity resulting in forest regeneration. This reclamation process does not affect the level of soil metal contamination but results in metals availability decrement. The coping mechanisms of birch … …American Journal of Environmental Sciences, Vol. 12, Issue 2 · 11 Apr 2016 · 7,535 accessesView PDFCite
Technical ReportOpen accessIn the abstractCorporate Network Analysis with IPTV Traffic InsertionFilipe Hiluy Lima, Henrique Mariano Costa do Amaral, Denílson Moreira SantosThis paper presents studies about Internet Protocol Television (IPTV) technology starting with its motivation that led to its birth and its great and current application. The article theoretical basis will present the description of mechanisms, standards and main protocols used to ensure a quality of service needed to the deployment of IPTV applications. Among them, we will mention Multiprotocol Label … …Journal of Computer Science, Vol. 11, Issue 5 · 29 Jul 2015 · 6,802 accessesView PDFCite
EditorialOpen accessIn the abstractRe-Paving the Road Built by Chemistry: A Challenge to Biochemistry and BiotechnologyAlberto A. IglesiasBiochemistry’s birth can be placed at the end of the nineteenth century, when Eduard Buchner made a clever interpretation of experimental observations on the generation of gas bubbles after addition (the original purpose was preservation) of sucrose to a yeast crude extract (Lagerkvist, 2005). Intelligently, Buchner concluded that the disaccharide had been fermented by broken cells’ suspension to produce CO2, … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 1 · 26 Jan 2015 · 7,461 accessesView PDFCite
Research ArticleOpen accessIn the abstractCARING MORE BY DOING LESS? AN ENQUIRY ABOUT THE IMPACTS OF OUTSOURCING ON PATIENT CAREFederica Brunetta, Luca Giustiniano, Lucia MarchegianiThis study seeks to understand the potential impact of outsourcing on healthcare processes. By referring to a wider scope of industries and sectors, as they have been the experimental fields of most of the studies on outsourcing, we highlight the pros and cons of the externalization of activities related to patient care. Our purpose is to show and contextualize the … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 24 Dec 2013 · 7,909 accessesView PDFCite
Research ArticleOpen accessIn the abstractREMEDIAL EFFECTS OF VITAMIN E AND L-ARGININE ON PERIPHERAL NEUROPATHY IN STREPTOZOTOCIN-INDUCED DIABETIC RATSIsmaeel Bin-Jaliah, Samah El-Attar, Eman F. Khaleel et al.It was shown that hyperglycemia in diabetic patients is the main factor of diabetic peripheral neuropathies. Various pathways related to oxidative stress, vascular defect and defective endothelium dependent relaxation have been implicated in the development of diabetic peripheral neuropathy. A substantial number of studies have shown that antioxidant treatment are promising therapeutics that can prevent or correct reduced motor nerve … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 1 · 23 Dec 2013 · 8,041 accessesView PDFCite
Research ArticleOpen accessIn the abstractA SURVEY: PARTICLE SWARM OPTIMIZATION-BASED ALGORITHMS FOR GRID COMPUTING SCHEDULING SYSTEMSFaruku Umar Ambursa, Rohaya LatipBio-inspired heuristics have been promising in solving complex scheduling optimization problems. Several researches have been conducted to tackle the problems of task scheduling for the heterogeneous and dynamic grid systems using different bio-inspired mechanisms such as Genetic Algorithm (GA), Ant Colony Optimization (ACO), Particle Swarm Optimization (PSO). PSO has been proven to have a relatively more promissing performance in dealing … …Journal of Computer Science, Vol. 9, Issue 12 · 25 Nov 2013 · 6,656 accessesView PDFCite
Research ArticleOpen accessIn the abstractTRANSMISSION CONTROL PROTOCOL PERFORMANCE COMPARISON USING PIGGYBACK SCHEME IN WLANSAli Ahmad Milad, Zul Azri Bin Muhamad Noh, Abdul Samad Shibghatullah et al.The main problem at wireless networks is the overhead at MAC layer; when the data physical rate is increasing it causes increasing the overhead and decreasing at the MAC efficiency. In this study we study the performance comparison of TCP protocol in WLANs with and without using piggyback. The study of results concerning of implemented both mechanisms in NS2 simulator … …Journal of Computer Science, Vol. 9, Issue 8 · 2 Jul 2013 · 7,360 accessesView PDFCite
