Research ArticleOpen accessIn the abstractDistribution of Alleles and Genotypes of ACE2 Gene Polymorphisms (rs2285666 and rs35803318) and Association with COVID-19 Among Populations in KazakhstanAnar Bisseneva, Konstantin Li, Gayane Pogossyan, Valeriya ProtasThere is still no definitive confirmation regarding the association between ACE2 gene polymorphisms and COVID-19. This study was conducted to analyze the distribution of alleles and genotypes of the ACE2 gene rs2285666 and rs35803318 two polymorphisms and their possible association with COVID-19 among two ethnic groups, namely, the Kazakhs and Eastern Slavs, residing within the same geographic area in the … …OnLine Journal of Biological Sciences, Vol. 24, Issue 1 · 31 Oct 2023 · 4,942 accessesView PDFCite
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 abstractSecondary User Sensing Time Optimization in Sensing-Transmission Scheduling for Dynamic Spectrum Access in Cognitive RadioInderdeep Kaur Aulakh, Renu VigThe constraint of limited frequency spectrum for wireless communication is very daunting. The radio spectrum licensed to permanent users is wasted at times when not used continuously. Cognitive radio technology involves a change in regulation of radio spectrum. In cognitive radio networks a secondary user network is designed for efficiently using gaps in spectrum and not causing at the same … …Journal of Computer Science, Vol. 11, Issue 8 · 5 Nov 2015 · 7,343 accessesView PDFCite
Research ArticleOpen accessIn the abstractPERMUTATION OF HTTPI AND HTTPS IN WEB SERVICES AGAINST ATTACKS FOR SECURITY ENHANCEMENTS. Chakaravarthi, V. RamachandranThe Hyper Text Transfer Protocol (HTTP) protocol plays a vital role in Web Services Security. Though the HTTPs provide excellent security, they are not flexible enough to allow caches. HTTPi provides high integrity and low security whereas HTTPs provide low integrity and high security. The goal of WS activity is to build up set of technologies in order to direct … …Journal of Computer Science, Vol. 10, Issue 3 · 30 Nov 2013 · 6,884 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Impact of Anthropogenic Activities Recorded By Mercury in the Sediment from Dianshan LakeHui Zhang, Nan Zhang, Qi Yang et al.The mercury in sediment cores from Dianshan Lake, Shanghai is studied in this study and it indicates that the mercury level changing from 52.78-145.66 µg kg-1 in sediment can be obviously divided into three sections responding to the development of economy of Shanghai. Mercury decreases with depth in 0-11 cm underground, which is corresponding to the depositing period after 1980; … …American Journal of Environmental Sciences, Vol. 8, Issue 4 · 4 Aug 2012 · 7,018 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Chaotic Block Cipher for Real-Time MultimediaN. Radha, M. VenkatesuluProblem statement: The widespread use of image, audio and video data makes media content protection increasingly necessary and important. We propose a naive approach which treats the multimedia signal to be protected as a text and use proposed encryption design to encrypt the whole data stream. Upon reception, the entire cipher text data stream would be decrypted and playback can … …Journal of Computer Science, Vol. 8, Issue 6 · 27 Apr 2012 · 7,306 accessesView PDFCite
