Research ArticleOpen accessIn the abstractStrengthening Image Security with Unimodular Hill Cipher and Advanced Encryption StandardSamsul Arifin, Dwi Wijonarko, Monica Mayeni Manurung et al.Digital data security has become increasingly important with the growth of digital image usage, which often contains sensitive information. This study aims to enhance the security of digital images by combining Unimodular Hill Cipher (UHC) and Advanced Encryption Standard (AES) methods. UHC, a matrix-based symmetric encryption algorithm, is used for image matrix encryption, while AES provides an additional layer of … …Journal of Computer Science, Vol. 21, Issue 5 · 22 Apr 2025 · 5,419 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Overview of the Antimicrobial Activity of Some Microbial EnzymesAkram N. Salah, Hayam Atallah AlwabsiEnzymes are substances produced by living organisms that are used to catalyze some biological and biochemical reactions as they either catalyze some types of polysaccharides and proteins or lyse complex materials such as polymers and lipids. Microbial enzymes are defined as the enzymes that can be extracted and purified from bacterial strains such as Bacillus spp., Pseudomonas spp., Streptomyces, or … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 2 · 11 Jun 2024 · 6,091 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenetic Diversity of Red Chittagong Cattle Using Randomly Amplified Polymorphic DNA MarkersMohammad Masud Rana Mufti, Mst. Parvin Mostari, Gautam Kumar Deb et al.Problem statement: Red Chittagong Cattle (RCC) is a potential genetic resource in Bangladesh having dairy potentialities, high resistance to disease and survive harse environmental condition while require low input supply. This resource is now disappearing due to indiscriminate crossing with other local and exotic cattle. To conserve this resource, find out the genetic diversity of RCC is prime concern. Approach: … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 1 · 17 Mar 2009 · 8,682 accessesView PDFCite
Research ArticleOpen accessIn the abstractUse of Novel Triphenyltin (IV) Dithiocarbamate Compounds in Assessing the Cytotoxicity and Mode of Cell Death of Acute Lymphoblastic Leukemia Cell Lines, CCRF CEM (CCL-119)Normah Awang, Nur Hidayah Hasrin, Nurul Farahana Kamaludin et al.Chemotherapy and radiotherapy are often used to treat Acute Lymphoblastic Leukemia (ALL). However, the resistance problem of treatment using the current drug in ALL patients has decreased the effectiveness of such therapy. Therefore, a study needs to be conducted to identify the potential of new anticancer agents. Organotin (IV) dithiocarbamate, an organometallic compound, causes toxic effects on cancer cells in … …OnLine Journal of Biological Sciences, Vol. 23, Issue 2 · 10 Mar 2023 · 5,161 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Unified Approach for the Shear Buckling Design of Structural Glass Walls with Non-Ideal RestraintsChiara Bedon, Claudio AmadioIn this study, a unified design approach is assessed and proposed for the shear buckling verification of structural glass walls supported by non-ideal restraints. Based on the current trends of practice in buildings, the effect of (i) adhesive joints, (ii) metal frames with interposed adhesive joints or (iii) point mechanical connectors on the actual shear buckling behavior of the examined … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 1 · 22 Jan 2016 · 8,292 accessesView PDFCite
Research ArticleOpen accessIn the abstractANTIBACTERIAL ACTIVITY EVALUATION OF 15 EUCALYPTUS SPECIES ESSENTIAL OILS AGAINST CLINICALLY RELEVANT PATHOGENIC BACTERIADias C., V. Pereira, M.C.B.M. De Vasconcelos et al.This study aims to evaluate the potential of 15 Eucalyptus species essential oils as alternatives to clinical surface disinfectants with known association to antibiotic resistance. Four reference pathogenic bacteria were tested: Pseudomonas aeruginosa (ATCC10145), Escherichia coli (CECT434), Staphylococcus aureus (CECT976) and Listeria monocytogenes (ATCC15313). Gram-positive bacteria revealed higher sensitivity than Gram-negative. Essential oils from E. bosistoana, E. botryoides, E. camaldulensis, … …Current Research in Microbiology, Vol. 5, Issue 2 · 22 Apr 2015 · 7,924 accessesView PDFCite
Research ArticleOpen accessIn the abstractFrictional Properties of Self-Ligating Brackets and Low-Friction LigaturesMaria Francesca Sfondrini, Danilo Fraticelli, Federico Rosti et al.Problem statement: To evaluate the frictional forces generated by five different orthodontic brackets when used in combination with stainless steel and NiTi archwires in dry conditions at physiological temperature. Approach: Five different types of maxillary canine brackets (Damon 3 MX, Step, Quick, Sprint, Mini Mono) with a slot size 0.022 inch were coupled with 0.016” and 0.019”×0.025” stainless steel and … …Current Research in Dentistry, Vol. 3, Issue 1 · 9 Mar 2012 · 13,064 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntibacterial Activity of Marine Source Extracts Against Multidrug Resistance OrganismsNagi A. AL-Haj, Nurmas I. Mashan, Mariana N. Shamsudin et al.Problem statement: Antimicrobial resistance is the major problem of global dimensions with a significant impact on morbidity, mortality and healthcare-associated costs. The problem has recently been worsened by the steady increase in multiresistant strains and by the restriction of antibiotic discovery and development programs. Methicillin-resistant Staphylococcus aureus, pseudomonads and Escherichia coli are a major nosocomial and community-acquired pathogens for which … …American Journal of Pharmacology and Toxicology, Vol. 5, Issue 2 · 30 Jun 2010 · 10,078 accessesView PDFCite
Research ArticleOpen accessIn the abstractIn situ Shear Tests of Soil Samples with Grass Roots in Alpine EnvironmentE. Comino, A. DruettaProblem statement: The presence of vegetation increases the soil burden stability along slopes and reduces soil erosion. Its contribution is due to mechanical (reinforcing soil shear resistance) and hydrologic controls on streambank and superficial landslides. This study presented the results carried out from experimental in situ test focused to study the increased shear resistance of soil blocks due to root-reinforcement. … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 7,262 accessesView PDFCite
Research ArticleOpen accessIn the abstractReinforcing Effect of Strain Gauges on 3D Printed Polymers: An Experimental InvestigationSalvatore Brischetto, Roberto TorreStrain gauges are ordinary transducers for strain measuring; their operation relies on the electrical resistance, which varies as the underlying substrate is subjected to mechanical deformation. The mechanical strain can be obtained by converting the electrical signal through a gauge factor, provided by the manufacturer. It was demonstrated that its values are not unique; it may be influenced by the … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 9 Jan 2021 · 7,662 accessesView PDFCite
