Research ArticleOpen accessEvery word in the titleCoupling Analysis of Thermodynamic Equilibrium of Mass Transfer and Microbial Community Succession in Multiphase System of Dark Tea Solid-State FermentationZhanjun Liu, Jiawei Sun, Taotao Li et al.During the solid-state fermentation of dark tea, the limited material migration, the dynamic evolution of the thermodynamic equilibrium state, and the highly dynamic succession of the microbial community make it difficult to analyze the quality formation mechanism systematically. Traditional research has focused on microbial diversity or sensory quality analysis, lacking a systematic discussion on the regulatory effects of material migration … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 10 Aug 2026 · 1,004 accessesView PDFCite
Research NotesOpen accessEvery word in the titleA Study on Dark Triad Personality and Emergency Response and Psychological Adaptation Among Young Adults During PandemicSidrah Jamal, Sandhya BhattThe present research was titled “A Study on Dark Triad Personality and emergency response and psychological adaptation among young adults during pandemic.” The purpose of the study was to explore the association between the dimensions of dark triad personality namely narcissism, psychopathy, Machiavellianism and the dimensions of emergency response and psychological adaptation namely worry, agitation, awareness, prosociality, and perceived self-efficacy. … …Current Research in Psychology, Vol. 10, Issue 1 · 28 Nov 2023 · 10,408 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Hypothesis Which Supports the Possibility of the Existence of Dark Matter with Negative MassFlorian Ion Tiberiu PetrescuThe paper presents an algorithm for calculating the negative mass of an atomic electron, a fact that from a physical point of view shows the possibility of the existence of the matter with the negative mass that could constitute the dark matter that separated from the normal matter with the positive mass due to the huge masses of different matter … …American Journal of Applied Sciences, Vol. 17, Issue 1 · 23 Jan 2020 · 7,918 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDeficient Reasoning for Dark Matter in GalaxiesJames Q. Feng, C.F. GalloIn this universe, not all of the matter around us can be readily seen. The further an object is away from us and the less luminous it is, the less visible it becomes. Just by looking at an object is usually difficult, if not impossible, to tell the amount of mass it contains. But astronomers have been using the measured … …Physics International, Vol. 6, Issue 1 · 14 Sep 2015 · 8,285 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleON THE ABSENCE OF ANTIMATTER FROM THE UNIVERSE, DARK MATTER, THE FINE STRUCTURE PARAMETER, THE FLUCTUATIONS OF THE COSMIC MICROWAVE BACKGROUND RADIATION AND THE TEMPERATURE DIFFERENCE BETWEEN THE NORTHERN AND SOUTHERN HEMISPHERE OF THE UNIVERSEEmmanuil ManousosThe theory of selfvariations correlates five cosmological observations considered to be unrelated by the physical theories of the previous century. The absence of antimatter from the Universe, the Dark Matter, the slight variation of the fine structure parameter, the temperature fluctuations of the cosmic microwave background radiation and the temperature difference between the northern and southern hemisphere of the Universe … …Physics International, Vol. 5, Issue 1 · 28 Nov 2014 · 8,881 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOptimal Dark Current Reduction in Quantum Well 9 µm GaAs/AlGaAs Infrared Photodetectors with Improved DetectivityShahram Mohammad Nejad, Saeed Olyaee, Maryam PourmahyabadiIn this research, an optimization approach is presented to decrease the dark current in GaAs/AlGaAs QWIPs. The dark current noise is reduced by increasing Al density in barriers, decreasing detector dimensions and increasing the periodic length of the structure. In addition, increasing the number of periods can reduce both the dark current and responsivity. Therefore, devices can be optimally designed … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 7,188 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleKnowledge of Chemical Hazards and Prevalence of Darkroom Diseases among Darkroom Technicians and Assistants in Southeast, NigeriaMark C. Okeji, Felicitas U. Idigo, AngelMary C. Anakwue, Uloma NwoguDarkroom technicians and assistants are exposed daily to x-ray processing chemicals. These chemicals contain known irritants which can cause some disease symptoms to its handlers. The aim of this study was to assess the knowledge of chemical hazards and prevalence of darkroom diseases among darkroom technicians and assistants in Southeast, Nigeria. The study adopted cross-sectional survey. A total of 105 … …Current Research in Medicine, Vol. 6, Issue 2 · 24 Nov 2015 · 8,126 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDetermining the Impact of Darkness on Highway Traffic Shockwave PropagationParameswary Sundara, Othman Che Puan, Mohammad Rosli HaininDuring darkness visibility diminishes resulting in reduced sight distances and drivers are subjected to anxiety that may give way to anger and frustration. However, the study is concerned with traffic shockwave propagation that could be associated with darkness on highways. Based on the hypothesis that darkness may induce temporary traffic shockwave propagation in the presence of substantial traffic volume, darkness … …American Journal of Applied Sciences, Vol. 10, Issue 9 · 24 Aug 2013 · 7,071 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInhibition of Skin Colour Darkening (Skin Clearing and Lightening); Skin Firming; Body Calming and Body Vitalizing Effects of Vernonia amygdalina Leaf ExtractUtoh-Nedosa Uchechukwu AnastasiaProblem statement: Obese human subjects treated with oral Vernonia amygdalina (V. amygdalina) aqueous leaf extract for one month who experienced the anti-obesity effects of V. amygdalina leaf extract reported a lighter; clearer; more glowing and firmer skin as side effects of the treatment (unpublished findings). In this study, oral Vernonia amygdalina aqueous leaf extract was taken daily for six months … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 2 · 17 Aug 2011 · 8,259 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFinite Bounded Expanding Carmelian White Hole Universe Without Dark MatterJohn Gideon HartnettThe solution of Einstein’s field equations in Cosmological General Relativity (CGR), where the Galaxy is at or cosmologically near the center of a finite yet bounded spherically symmetrical isotropic gravitational field, is identical with the unbounded solution. I show that this leads to the conclusion that the Universe may be viewed as a finite expanding white hole. The fact that … …Physics International, Vol. 3, Issue 2 · 7 May 2013 · 6,935 accessesView PDFCite
