Research ArticleOpen accessEvery word in the titleEarly Responses of Neural Cells (U87) to Particulate Matter Exposure: Cell Viability and Cytokine ConcentrationJae-Sik Jeon, Eun Ju Oh, Qian-Wen Wang, Jae Kyung KimParticulate Matter (PM) has a significant impact on human health and increases the risk of respiratory diseases. PM exposure is linked to various illnesses, including cardiovascular diseases, cancer, neurological diseases, and pregnancy complications, and contributes to both mortality and morbidity globally. PM can also influence the autonomic nervous system. The evidence suggests that the likelihood of developing lung cancer continually … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 1 · 20 Feb 2023 · 5,450 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 titleElementary Structure of Matter can be Studied with New Quantum ComputersNicolae Petrescu, Florian Ion Tiberiu PetrescuMuch has been talked about quantum computers. Today they are working on difficult simulations, so we can already congratulate the college of researchers at the Oak Ridge National Laboratory as the world's first to successfully simulate an atomic nucleus using a quantum computer. The results that were published in the physical examination letters demonstrate the huge capacity of quantum systems … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 25 Jun 2018 · 7,698 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCompaction Properties of Silty Soils in Relation to Soil Texture, Moisture Content and Organic MatterPrathuang Usaborisut, Jettapol AmpanmaneeSoil compaction is recognized as an increasingly challenging problem with regard to root growth and yield reduction in agricultural production in Thailand. The aim of this research was to study the effect of soil texture, moisture content and organic matter on the compaction properties of silty soils. Three soils with different silt contents were studied-loam, silty clay loam and silt … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 4 · 31 Dec 2015 · 9,536 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 titleParticulate Matter in the Excavation Work Sites in Urban AreasGiuseppe Pizzo, Marina ClericoProblem statement: Excavation work sites in urban areas for infrastructures and buildings cause a great deal of disturbance and damage due to the emission of particulate matter, in particular in the area involved in urban renovation work. Under Italian legislation limits currently exist for PM10 and PM2, 5 but, in the case of excavation work sites, it would be also … …American Journal of Environmental Sciences, Vol. 7, Issue 6 · 23 Dec 2011 · 6,825 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleFemtotechnology: Nuclear Matter with Fantastic PropertiesA. A. BolonkinProblem statement: At present the term 'nanotechnology' is well known-in its' ideal form, the flawless and completely controlled design of conventional molecular matter from molecules or atoms. Such a power over nature would offer routine achievement of remarkable properties in conventional matter and creation of metamaterials where the structure not the composition brings forth new powers of matter. But even … …American Journal of Engineering and Applied Sciences, Vol. 2, Issue 2 · 30 Jun 2009 · 8,681 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOrganic Matter, Carbon and Humic Acids in Rehabilitated and Secondary Forest SoilsLee Yit Leng, Osumanu Haruna Ahmed, Nik Muhamad Ab. Majid, Mohamadu Boyie JallohProblem Statement: Tropical rainforests cover about 19.37 million ha (60%) of Malaysia’s total area and about 8.71 million ha can be found in Sarawak, Malaysia. Excessive logging, mining and shifting cultivation contribute to deforestation in Sarawak. The objectives of this study were to: (i) Quantify soil Organic Matter (SOM), Soil Organic Carbon (SOC) and Humic Acids (HA) in rehabilitated and … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,761 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHard Coal Fly Ash and Silica-Effect of Fine Particulate Matter Deposits on Brassica chinensisChristian Ulrichs, Uwe Schmidt, Tanja Mucha-Pelzer et al.Problem statement: One focus in recent atmospheric pollution research is on fine Particle Matter (PM), especially as result of increasing traffic and anthropogenic activity in urban areas. Here, the impact on animal and human health has been in the center of many studies. Despite the fact that PM depositions can affect plants on the long term, there are only few … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 1 · 31 Mar 2009 · 8,648 accessesView PDFCite
