Research ArticleOpen accessEvery word in the titleAging Study and Lifetime Estimation of Transformer Mineral OilMohammad R. MeshkatoddiniProblem statement: Power transformer is the most expensive equipment in electrical network; and the mineral oil has the main roles of insulating and cooling in it. Oil is subjected to the degradation because of the ageing, high temperature and chemical reactions such as the oxidation. Then the oil condition has to be checked regularly and reclaimed or replaced when necessary, … …American Journal of Engineering and Applied Sciences, Vol. 1, Issue 4 · 31 Mar 2008 · 11,100 accessesView PDFCite
Literature ReviewOpen accessIn the keywordsAtherosclerosis as Age-Related Disease: The Potential of Sirtuins TreatmentAnastasia Vladimirovna Poznyak, Victor Yurievich Glanz, Vasily Nikolaevich Sukhorukov et al.Atherosclerosis, a global health concern, has attracted researchers worldwide due to its severe consequences. The elderly are particularly susceptible to cardiovascular diseases and events, making them a high-risk group. Although gaps in our understanding of atherosclerosis pathogenesis persist, it is evident that oxidative stress, endothelial dysfunction, inflammation, mitochondrial dysfunction, and autophagy impairments are key components of its development. Remarkably, these … …OnLine Journal of Biological Sciences, Vol. 24, Issue 4 · 16 May 2024 · 4,717 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMechanical and Microstructural Characterization of Plasma Welded Joints of 18 Ni-300 Maraging Steels Subjected to RepairsPaulo Roberto Sakai, Deivid Ferreira da Silva, Milton Sérgio Fernandes de Lima et al.Among the ultra-high strength structural steels, 18Ni-300 Maraging steel is one of the most important for the naval and aerospace industries. For example, in the manufacture of motor envelopes Plasma Arc Welding-PAW processes are used with the keyhole technique. The joints are regions of high responsibility and undergo a non-destructive inspection according to the standardized technical criteria. If there is … …Journal of Aircraft and Spacecraft Technology, Vol. 5, Issue 1 · 19 Apr 2021 · 7,599 accessesView PDFCite
Research ArticleOpen accessIn the keywordsStudy the Relationship between the Microstructure and Characteristics of Quinoa Starch by Compared with Common Cereal StarchesMenyue Jiao, Yumei Gao, Yiling TianThe amylose and amylopectin contents, viscoelastic properties, freeze-thaw stability and Scanning Electron Micrographs (SEM) of quinoa (Chenopodium quinoa Willd) were studied to explore the microstructural property relationships. Compared with wheat, corn, rice and waxy rice starches, quinoa starch had special characteristics connected to its unique microstructure. The high ratio of amylopectin to amylose (12.03) in quinoa starch affected its functional … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 4 · 17 Dec 2020 · 7,256 accessesView PDFCite
Case ReportOpen accessIn the keywordsConsumption of an Extremely Biodiverse Probiotic and a Supplement based on Microbial Chondroitin Sulfate is Associated with Very Low Serum Alpha-N-acetylgalactosaminidase (Nagalase) Activity and Decrease of C-reactive Protein ValuesMichael Carter, Stefania Pacini, Marco RuggieroWe describe the case of a 57-years-old male healthy professional who added to his nutritional plan a novel, extremely biodiverse, probiotic and a supplement based on microbial chondroitin sulfate, vitamin D3 and ultrapure phosphatidylcholine to improve his healthy life expectancy. After three months of such a nutritional regimen, serum alpha-N-acetylgalactosaminidase (nagalase) activity was 0.40 that is a value below the … …American Journal of Immunology, Vol. 16, Issue 1 · 22 Apr 2020 · 13,049 accessesView PDFCite
Research ArticleOpen accessIn the keywordsApplication of Bio-Modified Montmorillonite Clay to Enhance Asphalt Oxidation ResistanceShahrzad Hosseinnezhad, Elham H. Fini, Taher M. Abu-LebdehThis study evaluates the effectiveness of using a Bio-modified Nanoclay additive (BNC) to reduce the oxidative aging of asphalt pavements. The study results through X-Ray Diffraction analysis showed that the modification of montmorillonite clay with bio-modifier increased the basal d-spacing of clay. The resulting nanoclay with increased interlayer spacing was chosen for application in asphalt binder. Rheological characterization of clay-modified … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 31 Mar 2018 · 9,054 accessesView PDFCite
Review ArticleOpen accessIn the keywordsThe Triple Immune Argument; Surveillance/Evasion/ Senescence and the Increased Incidence of Acute Myeloid Leukemia Observed with AgeManar M. IsmailAML originates from genetic insults of hematopoietic stem and progenitor cells (HSPCs/HSCs) that was identified earlier as leukemia stem cells (LSCs). In quiescent state, trafficking immune cells are crucial for eradication of aberrant clones and obtaining balance between proliferation and apoptosis to maintain HSCs pool. Regulatory T-cells shield the HSCs from the inflammatory reactions by suppressing T- and B- cells. … …American Journal of Immunology, Vol. 13, Issue 4 · 22 Dec 2017 · 7,806 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAge-Dependent Variation of Telomere Length and DNA Damage in ChickenMaxim S. Makarenko, Alexander V. Usatov, Lyubov V. Getmantseva et al.Birds are unique models for molecular studies on aging processes and cellular senescence because of their slow rates of aging and comparatively long life spans among homoeothermic animals. The study aimed to examine the relative telomere length and amount of nuclear, mitochondrial DNA lesions in hens of different ages and to find out the correlation between these biomarkers of aging. … …OnLine Journal of Biological Sciences, Vol. 17, Issue 4 · 14 Dec 2017 · 7,505 accessesView PDFCite
Research ArticleOpen accessIn the keywordsPresent a Mechatronic System Having Able to Determine the Concentration of CarotenoidsRaffaella Aversa, Eleni Buzea, Relly Victoria V. Petrescu et al.Civilization besides its major advantages (undisputed) brought us some unhealthy habits which unfortunately have managed to penetrate deeply within several generations on the current planetary populations producing great damages to its health. Perhaps it would be the right time to and more people learning to live healthy, to feed ourselves healthy, let's try to break the chain of evil which … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 7 Dec 2016 · 8,567 accessesView PDFCite
Research ArticleOpen accessIn the keywordsInvestigating Bio-Char as Flow Modifier and Water Treatment Agent for Sustainable Pavement DesignRenaldo Walters, Shamim A. Begum, Elham H. Fini, Taher M. Abu-LebdehThe life expectancy of Asphalt Binder (AB) has been negatively impacted by the harsh bombardment of Ultraviolet (UV) rays. UV rays cause asphalt to oxidize faster, which results in the deterioration of asphalt's rheological characteristics that can lead to pavement distresses. This paper investigates merits of bio-char to improve asphalt aging susceptibility by blending one control binder (PG 64-22) and … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 22 Apr 2015 · 9,049 accessesView PDFCite
