Research ArticleOpen accessIn the author namesA Multinomial Logit Based Evaluation of the Behavior of the Life Insureds in RomaniaCristian Dragos, Simona DragosThe Romanian life insurance market is in full expansion. There exists competition between insurance companies as well as between different products of the same company. In this article we describe a study using data that we collected from clients of a Romanian insurance company. We have observed two types of variables: attributes of the insurance products (e.g., profitability, risk), as … …American Journal of Applied Sciences, Vol. 6, Issue 1 · 31 Jan 2009 · 7,753 accessesView PDFCite
Research ArticleOpen accessIn the author namesEvaluation of the Immunomodulatory Properties of a Calf Lipid Thymus Extract and Standardization of a Method for Quantification of its Biological ActivityMiodrag Colic, Radmila Popovic, Dusanka Mrdakovic et al.The aim of this study was to test the immunobiological properties of a new formulation of the lipid thymus calf extract (Thymsol), prepared for in vitro cell culture experiments. At first, we showed that Thymsol enhanced the antigen specific immune response in AO rats in vitro, using Keyhole limpet hemocyanin (KLH). At lower concentrations (0.5-2.5 μg mL-1) the extract increased … …American Journal of Immunology, Vol. 3, Issue 2 · 31 Dec 2007 · 7,039 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn Wing Tip Flow Around a Low Aspect Ratio Wing at Low Flight Speeds Using OpenFOAM® and Parallel ProcessingNikolaos Konstantinos Lampropoulos, Ioannis Eleftherios SarrisIn the present study, the effect of the wing tip geometry on the aerodynamic performance of a swept-back wing at moderate Reynolds numbers is investigated through numerical simulation and parallel processing. The aim is the identification of streamlines around the wing and subsequently the formation of the wing tip vortex. Due to the purely three-dimensional character of the flow, the … …Journal of Aircraft and Spacecraft Technology, Vol. 9, Issue 1 · 31 Jan 2025 · 9,538 accessesView PDFCite
Research ArticleOpen accessIn the abstractSocio-Economic Aspect of African Manatee (Trichechus Senegalensis) Hunting and Capturing in Parts of Ogun and Ondo State, Southwest NigeriaKabir O. Abass, Abiodun K. Seriki, Emmanuel O. Orebiyi et al.This research was carried out to understand the emerging practice of hunting, capturing and trading of African manatee (Trichechus senegalensis) by fishermen and hunters in Iwopin lagoon area of Ogun State and some parts of Ondo State, Southwest Nigeria. The African Manatee has been declared an endangered species under IUCN red list. This research was conducted over one year to … …American Journal of Agricultural and Biological Sciences, Vol. 15, Issue 1 · 18 Jun 2020 · 7,853 accessesView PDFCite
Research ArticleOpen accessIn the abstractSEVQER: Automatic Semantic Visual Query Builder to Support Intelligent Image Search in Traffic ImagesHui-Hui Wang, Phei-Chin Lim, Yin-Chai Wang et al.Image search is a challenging process in the field of Content Based Image Retrieval (CBIR). Image search-by-example, search-by-keyword and search-by-sketch methods seldom provide user interface that allows user to accurately formulate their search intent easily. To overcome such issue, a novel image search interface-Semantic Visual Query Builder (SeVQer) is proposed as a non-verbal interface which allows user to drag and … …Journal of Computer Science, Vol. 14, Issue 7 · 6 Aug 2018 · 7,680 accessesView PDFCite
Research ArticleOpen accessIn the abstractExperimental Investigation of Limonene-based Environmental-Friendly Emulsion Drilling MudOlaitan Oluwaseum Micheal, Orodu Oyinkepreye David, Ehinmowo Adegboyega BoluThe use of emulsion drilling mud in the oil and gas industry has gained wide acceptance. However, the disposal of drill cuttings and the waste of such emulsion drilling mud usually poses environmental concern. Hence, there is the need to seek oil from biodegradable sources as an alternative to the current conventional diesel oil which constitute environmental threat. In this … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 12 Jun 2017 · 7,923 accessesView PDFCite
Research ArticleOpen accessIn the abstractDegradation of Power Generation Performance due to Effects of Various Ice Shapes and Accretions on Wind Turbine BladesAditya Bagade, Changki Mo, Abdelhamid MazherIn today’s world, green energy has become a key initiative as an alternative energy resource. Wind turbines are widely used to harvest wind energy in seasonal and cold environments. Although efficient, cold weather conditions negatively affects wind turbine operations due to ice formation. Damage from icing is seen on blade-tips when super-cooled water droplets that form in colder environments rapidly … …Energy Research Journal, Vol. 6, Issue 2 · 11 Sep 2015 · 7,815 accessesView PDFCite
Research ArticleOpen accessIn the abstractEntrenching Inferences in Implicational and Illocutionary ConstructionsFrancisco José Ruiz de Mendoza IbáñezThe starting point for the present paper is the classification of constructions, understood as fixed pairings of form and meaning, into four levels of meaning representation, i.e., the argument-structure, implicational, illocutionary and discourse levels. The meaning part of constructions contains fixed and variable elements. In argument-structure constructions the fixed elements are generic and, as such, they are open to parameterization … …Journal of Social Sciences, Vol. 11, Issue 3 · 14 Aug 2015 · 8,199 accessesView PDFCite
Research ArticleOpen accessIn the abstractSimulation of the Cuttings Cleaning During the Drilling OperationHussain H. Al-Kayiem, Nadia Mohd Zaki, Muhamad Z. Asyraf, Mahir Elya ElfeelProblem statement: Oil well cleaning is the ability of a drilling fluid to suspend and transport drilled cuttings from the down hole (bit face) to the surface. The cleaning performance was affected by many factors such as fluid viscosity, annular flow velocity, angle of inclination and drill cuttings size and shape and. Approach: Navier-Stoke equations, the continuity equation and the … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 8,249 accessesView PDFCite
