Research ArticleOpen accessIn the abstractESTIMATIONS OF TOTAL MASS AND ENERGY OF THE OBSERVABLE UNIVERSEDimitar ValevThe recent astronomical observations indicate that the expanding universe is homogeneous, isotropic and asymptotically flat. The Euclidean geometry of the universe enables to determine the total gravitational and kinetic energy of the universe by Newtonian gravity in a flat space. By means of dimensional analysis, we have found the mass of the observable universe close to the Hoyle-Carvalho formula M∼c3/(GH). … …Physics International, Vol. 5, Issue 1 · 21 Mar 2014 · 17,696 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Induction of Lycopene in Germinating Cottonseed with 2-(4-Methylphenoxy) Triethylamine (MPTA)Lorraine S. Puckhaber, Jinggao LiuAbstract: Problem Statement: Increasing carotenoids content in foods was currently of great interest. The present paper reports strong stimulatory effect of MPTA on the carotenogenesis in cotton, which was used as a model. Approach: Cotton seedlings were treated with MPTA vs. water and germinated in the dark. The levels of carotenoids were determined by HPLC and the expression levels of … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 26 Jul 2011 · 7,950 accessesView PDFCite
Research ArticleOpen accessIn the abstractLead Phytotoxicity Induced Changes in Biochemical Markers in Germination and Seedlings in Durum Wheat Triticum durum Desf. Cv.Vitron and GtaSoraya Slimani, Mokhtar Boudelaa, Saddek Abdelmadjid et al.Among the heavy metals most commonly found on land, lead is a strongly represented pollutant in soil and sediments. It is easily absorbed and accumulated in different parts of plants. On the macroscopic scale, lead causes unfavorable effects on plants. First and in the event of excess, it may exert toxicity affecting several stages of germination development in leaf formation … …American Journal of Environmental Sciences, Vol. 13, Issue 4 · 6 Sep 2017 · 7,480 accessesView PDFCite
Research ArticleOpen accessIn the abstractSusceptibility of Mango Varieties to Anthracnose Fruit Rot in South West NigeriaCharles Awa OnyeaniAnthracnose fruit rot is the most devastating postharvest disease of mango fruits in Nigeria. This study, investigated the susceptibility of mango varieties commonly grown in South West Nigeria to fruit anthracnose. Four locations (Ayetoro, Ibadan, Ogbomosho and Agege) in South west Nigeria, which fall along mango production belt, were selected for this study. Physiologically matured mango fruits freshly harvested separately … …American Journal of Agricultural and Biological Sciences, Vol. 12, Issue 2 · 5 Apr 2017 · 8,833 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Occurrence of Entomopathogenic Fungi on Mineral and Peat Soils in Peninsular MalaysiaPong Kuan Kin, Wahizatul Afzan Azmi, Norman Kamarudin et al.The aims of this study are to isolate and identify Entomopathogenic Fungi (EPF) from mineral and peat soils in relation with the soil physico-chemical parameters. The mineral soil was sampled from the MPOB Research Station Hulu Paka in Terengganu, whereas peat soil was sampled from the MPOB Research Station Teluk Intan in Perak. Isolation of these fungi was carried out … …American Journal of Agricultural and Biological Sciences, Vol. 12, Issue 1 · 12 Jan 2017 · 8,203 accessesView PDFCite
Research ArticleOpen accessIn the abstractEarly Universe in the SU(3)L⊗U—(1)X Electroweak ModelsHoang Ngoc LongWe present status of the 3-3-1 models and their implications to cosmological evolution such as inflation, phase transitions and sphalerons. The models can deal not only with the issues such as neutrino physics, dark matter, etc, but they are also able to provide quite good agreement with the Standard Cosmology: The inflation happens at the GUT scale, while phase transition … …Physics International, Vol. 7, Issue 1 · 13 Nov 2015 · 7,935 accessesView PDFCite
Case ReportOpen accessIn the abstractEpistein-Barr Virus Infection with Concurrent Pancreatitis and Hepatitis: A Rare Disease EntityJered Cook, Megha Kothari, Andrew NguyenConcurrent acute hepatitis and acute pancreatitis is a rare disease entity. Most commonly it can be attributed to infectious etiologies such as hepatitis A, Hepatitis B and Hepatitis E. Although not as common, Epstein Barr Virus (EBV) should be considered in the differential diagnosis in patients with combined hepatitis and pancreatitis. We report a case of a 25 year-old male … …American Journal of Infectious Diseases, Vol. 11, Issue 3 · 18 Sep 2015 · 7,835 accessesView PDFCite
Research ArticleOpen accessIn the abstractColormap Development for Night Vision from Synthetic ImageryH. A. Qadir, S. P. KozaitisWe presented a method for colorizing fused imagery using a synthetic image as the color source. Imagery acquired at night from two sensors with different spectral bands were fused into a single image. We used a color transfer method based on a look-up table approach to change the false color appearance of the fused image to a natural appearance. Because … …American Journal of Engineering and Applied Sciences, Vol. 7, Issue 4 · 30 Dec 2014 · 8,086 accessesView PDFCite
EditorialOpen accessIn the abstractProblems of Ultra-High Energy Cosmic RaysAnna V. UrysonCosmic rays are energetic particles coming to the Earth from space. They bombard the atmosphere producing cascades of particles that spread over a large area when they reach the ground. Cosmic ray energies vary in the wide band from about 108 eV up to few 1020 eV. It is established that most particles with energies of ~ (108-109) eV come … …Space Science International, Vol. 2, Issue 1 · 6 Dec 2014 · 13,854 accessesView PDFCite
Research ArticleOpen accessIn the abstractPOTENCY OF HONEY AS ANTIBACTERIAL AGENT AGAINST MULTIPLE ANTIBIOTIC RESISTANT PATHOGENS EVALUATED BY DIFFERENT METHODSMohamed Mustafa Aween, Zaiton Hassan, Nur Huda-Faujani et al.Honey is rich with complex natural components which could be useful as antibacterial agents or as preservative. Honey contains high concentration of sugars, low amount of water, high osmolality and often dark colour which influence its antibacterial activity. Disc diffusion, well method, micro dilution assay are methods commonly used to determine the antibacterial activity of honey. In this study, microtiter … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 1 Dec 2014 · 6,564 accessesView PDFCite
