Research ArticleOpen accessIn the keywordsFabrication of Carboxymethyl Cellulose (CMC) Derived from Themeda gigantea Cellulose with Various Concentrations of Sodium MonochloroacetateDaimon Syukri, Heru Suryanto, Anni Faridah et al.The purpose of this study was to determine the properties of Carboxymethyl Cellulose (CMC) obtained from pimping stems (Themeda gigantea). There has yet to be a report on utilizing Themeda gigantea as a source of CMC raw materials. CMC was produced by varying the amount of Sodium Monochloroacetate (SMCA) as a carboxymethylation material. This study consisted of five SMCA treatments, … …OnLine Journal of Biological Sciences, Vol. 25, Issue 1 · 24 Oct 2024 · 5,147 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsA NOVEL SUBSTITUTION BOX DESIGN FOR HUMMING BIRD-2 AGAINST SIDE CHANNEL ATTACKT. Blesslin Sheeba, P. RangarajanThe side-channel attacks are one of the effortless and commanding attacks against cryptographic implementation and their intention vary from protocols, modules, primitives and system. As a result of this attack, a serious threat to the security of cryptographic module was encountered. In effect, realization of the cryptographic algorithm has to take some countermeasure to resist against this type of attacks. … …Journal of Computer Science, Vol. 10, Issue 9 · 23 Apr 2014 · 6,590 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAcetylation Process and Antioxidant Activity of a Polysaccharide from Loquat (Eriobotrya japonica) LeavesYiting Xue, Xiao Ding, Ze Zhang et al.Chemical modifications of polysaccharides can provide an opportunity to obtain new agents with possible therapeutic uses. In this study, a water-soluble polysaccharide extracted from Loquat Leaves (coded LLPs) was purified by the column chromatography, which was used to investigate its acetylation process by the acetic anhydride method. The Degree of Substitution (DS) was used as the index, the effect of … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 1 Jan 2021 · 7,056 accessesView PDF Cite

Research NotesOpen accessIn the abstractAn Artificial Design Technique to Optimize Signal PeptideGao Cui-Fang, Wang Sen, Tian Feng-Wei et al.To determine optimal artificial signal peptide candidates for the possibility of creating high levels of secretion of heterologous proteins, substitution and redesign of amino acid sequences in the H-domain of the signal peptide was theoretically attempted. The method was based on comprehensive score matrix and Markov transfer matrix, which can make the artificial sequences maintain the structural characteristics and original … …American Journal of Biochemistry and Biotechnology, Vol. 13, Issue 3 · 21 Jul 2017 · 8,063 accessesView PDF Cite

Research ArticleOpen accessIn the abstractMethod of Efficiency Improvement in District Heating SystemsAndrey Gennadiievich Batuhtin, Maxim Stanislavovich Bass, Sergey Anatoljevich Ivanov et al.The article determines application potential of solar energy in conditions of sharply continental climate. It presents an energy-efficient solar energy recovery scheme in district heating systems, allowing to reduce capital costs and maintenance charges and to increase degree of substitution of conventional sources of heat. Versatility of systems using this method results in its multi-zone application: From a cottage-type house … …American Journal of Applied Sciences, Vol. 13, Issue 2 · 1 Feb 2016 · 7,521 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPrivate Giving Crowding Government Funding in Public Higher EducationG. Thomas SavProblem statement: Private giving and government funding are critical revenue sources for public colleges and universities. If increased private giving reduces government funding, then that type and extent of crowding out carries important managerial and public policy implications. Approach: The study used a government funding reaction function and an instrumental variable approach to empirically estimate the potential for crowding out. … …American Journal of Economics and Business Administration, Vol. 2, Issue 3 · 30 Sep 2010 · 7,741 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAmphoteric Starch in Simultaneous Process Preparation with Box-Behnken Design for Optimal ConditionsSopa Cansee, Juntanee Uriyapongson, Commueng Watyotha et al.Cassava starch was chemically modified to produce an amphoteric starch. The amphoteric starch was prepared in a simultaneous process which was evaluated in relation to four factors: temperature (45-55 Â°C), 3-chloro-2-hydroxypropyltrimethylammonium chloride (CHPTAC, 4-12%) and sodium tripolyphosphate (STP, 2-8%) concentrations, and reaction time (2-6 h). The extent of amphoteric starch produced was determined by the degree of substitution (DS) of … …American Journal of Applied Sciences, Vol. 5, Issue 11 · 30 Nov 2008 · 7,523 accessesView PDF Cite
