Research NotesOpen accessEvery word in the titleSocial Stratification Principles in Santa Claus, Tooth Fairy and Easter Bunny: A Content AnalysisToni Y. Sims-Muhammad, D.A.H.This paper is a content analysis about social stratification principles in popular culture fairytale characters Santa Claus, Tooth fairy and Easter bunny. Specifically, this paper explores how these fairytale characters may contribute to an entitlement identification construct of the African American child. The researcher argues that there are three major components of social stratification portrayed by the fairytale characters (1) … …Journal of Social Sciences, Vol. 15, Issue 1 · 24 Jul 2019 · 7,770 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleMotor Oil Viscosity Stratification in Friction Units of Marine Diesel MotorsSergey Viktorovich Sagin, Oleksandr Vladymyrovich SemenovThe phenomenon of the motor oil viscosity stratification in lubricating the cylinder-piston units of marine diesel engines has been investigated. The correlations for determining the shear stress and the velocity, occurring in the liquid flow between the parallel planes, have been given. The modes of the hydrodynamic and the boundary lubrication, taking place in the cylinder assembly of the marine … …American Journal of Applied Sciences, Vol. 13, Issue 2 · 15 Feb 2016 · 8,011 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleTHE INFLUENCE OF THE INTEGRATED MODEL OF SOCIAL STRATIFICATION STRUCTURE ON THE PUBLIC PARTICIPATING NON-PROFIT ORGANIZATIONSYu-Tien Huang, Ming-Shen WangThe main body of social stratification structure in Taiwan is transformed with social mobility. By transforming the social stratification structure, the function of non-profit organizations is operating steadily. How does people’s awareness of social strata directly or indirectly influence the operation of non-profit organizations? How do non-profit organizations and governments respond to the transformation of social stratum compositions? And how … …Journal of Social Sciences, Vol. 9, Issue 4 · 23 Jan 2014 · 7,280 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleVariable Viscosity, Chemical Reaction and Thermal Stratification Effects on Mixed Convection Heat and Mass Transfer along a Semi-Infinite Vertical PlateP. Geetha, M.B.K. MoorthyProblem statement: In this research the researchers studied and made an analysis to the heat and mass transfer characteristics in a viscous fluid over a semi-infinite vertical porous plate by taking into account the variable viscosity, chemical reaction and thermal stratification effects. Approach: The governing partial differential equations were transformed into a set of coupled non-linear ordinary differential equations, which … …American Journal of Applied Sciences, Vol. 8, Issue 6 · 13 Jun 2011 · 6,848 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleNumerical Comparison of Thermal Stratification due Natural Convection in Densified LOX, LN2 TanksSeyed Ali Jazayeri, Ehsan Molla Hasanzadeh KhoeiThe growth of natural circulation and thermal stratification inside LOX, LN2 storage tanks due to heat transfer from surroundings is investigated using a non-equilibrium, two-domain, mathematical model. The two-dimensional model is considered for the liquid domain in two cases and a lumped, thermodynamic model is utilized for vapor domain. The vapor is assumed to behave like an ideal gas. The … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 6,967 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSimulation of Thermal Stratification in Urban Man-made LakesJ. Nouri, H. Rahimipour, R. NezakatiChitgar artificial lake, located in the urban District-22 Municipality of Tehran northwest of Tehran, Iran is by volume l0 Million Cubic Meter (MCM), by depth average 10 meters (m.) and by area 225 hectares (ha) as the Iran’s largest man-made lake. The most important water resources of the district, which can support the lake water, are Kan River, municipal runoff, … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 7,189 accessesView PDFCite
Research ArticleOpen accessIn the keywordsGermination Ecology of Rhanterium epapposum Oliv.Sameeha Zaman, Shyamala Padmesh, Harby TawfiqProblem statement: Rhanterium epapposum, locally called Arfaj is the national flower of Kuwait. The current situation of Rhanterium epapposum is quite critical in most areas of Kuwait. In fact it has completely disappeared from most parts of the country due to a combination of overgrazing, collecting for firewood and off road driving. Approach: Rhanterium epapposum is an excellent species for … …American Journal of Applied Sciences, Vol. 7, Issue 10 · 31 Oct 2010 · 7,618 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSeed Germination and Seedling Survival of Spartina alterniflora LoiselPatrick D. Biber, John D. CaldwellSpartina alterniflora (smooth cordgrass) is a widespread intertidal salt marsh plant that is frequently used in coastal restoration projects. Seeds collected in 2004 were tested for seed germination and seedling survival after 6 months of cold seed storage to determine differences among collection locations (experiment 1). Seeds collected in 2005, after Hurricane Katrina, were tested for seed germination and seedling … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 3 · 30 Sep 2008 · 8,704 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNumerical Study of the Eulerian Correlations and Lagrangian Velocity in Stably Stratified Homogeneous TurbulenceAbdallah Jaouabi, Taieb LiliThis study is based on a linear analysis in spectral space. To express the correlation double speed using Lagrangian Dual Eulerian correlations, we use the Corrsin assumption and then we compute the components of the tensor of the square displacements means. We begin by rewriting the basic linear equations governing the evolution of double correlations spectra. Subsequently, we analyze the … …American Journal of Applied Sciences, Vol. 10, Issue 5 · 28 May 2013 · 6,492 accessesView PDFCite
Research ArticleOpen accessIn the keywordsMacroinvertebrate Communities Differences on Riverine Parts and Reservoirs of Zarrineh RiverR. Ahmadi, A. Aliyev, M. Seidgar et al.This study was conducted to identify present macro invertebrate’s fauna in reverine and reservoir parts of the Zarrinehrood River for fisheries purposes. The abundance and species composition of macro invertebrate were analyzed and compared in various parts of the Zarrinehrood River (west Azerbaijan, Iran) during November 2008-February 2009 to evaluate the rivers benthic fauna as a resource of fish and … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 1 · 24 Feb 2012 · 8,150 accessesView PDFCite
