4-H as a catalyst to enhance quality of life for hispanic individuals
No full textImproving the quality of life for all Americans by increasing economic opportunities is essential to maintaining a highly competitive agricultural system in a global economy. Because Hispanic individuals are one of the fastest growing groups of Americans, traditional youth development programs must begin to focus more on Hispanic youth development. This article outlines how 4-H Programs can serve as a catalyst to enhance quality of life for Hispanic youth and citizens in general. © by Extension Journal, Inc

Understanding the Role and Decision-Making Process of the Juvenile Court Judge: A Descriptive Survey
Get PDFCatalysis of a new ribose carbon-insertion reaction by the molybdenum cofactor biosynthetic enzyme MoaA
No full textMoaA, a radical S-adenosylmethionine enzyme, catalyzes the first step in molybdopterin biosynthesis. This reaction involves a complex rearrangement in which C8 of guanosine triphosphate is inserted between C2′ and C3′ of the ribose. This study identifies the site of initial hydrogen atom abstraction by the adenosyl radical and advances a mechanistic proposal for this unprecedented reaction. © 2013 American Chemical Society
Chemical Reaction and Hall Effects on MHD Convective Flow along an Infinite Vertical Porous Plate with Variable Suction and Heat Absorption
Get PDFIn this paper an attempt is made to study the chemical reaction and combined buoyancy effects of thermal and mass diffusion on MHD convective flow along an infinite vertical porous plate in the presence of Hall current with variable suction and heat generation. A uniform magnetic field is applied in a direction normal to the porous plate. The equations governing the fluid flow are solved using the perturbation technique and the expressions for the velocity, the temperature and the concentration distributions have been obtained. Dimensionless velocity, temperature and concentration profiles are displayed graphically for different values of the parameters entering into the problem like Prandtl number Pr, Hartmann number M, Grashof number G, modified Grashof number Gc, Hall parameter m, Heat source parameter δ, Schmidt number Sc, and Chemical reaction parameter Kr. The Skin-friction coefficient, rate of heat transfer and mass transfer at the plate have been obtained and also discussed through tables. It has been observed that an increase in the Prandtl number leads to a decrease in the primary and secondary velocities, and also a decrease in the primary and secondary temperatures. The primary and secondary velocities decrease with increase in the Chemical reaction parameter or Magnetic field parameter
Mathematical Modelling of Blood Flow through Catheterized Artery under the Influence of Body Acceleration with Slip Velocity
Get PDFThe flow of blood through stenosed catheterized artery with the effect of external body acceleration has been considered. The pulsatile flow behaviour of blood in an artery subjected to the pulsatile pressure gradient and slip velocity has been studied considering blood as a Newtonian fluid. The non-linear differential equations governing the fluid flow are solved using the perturbation method. The analytic expressions are derived for the velocity profile, flow rate, wall shear stress and effective viscosity. The computer codes are developed for the analysis of physiological parameters. The effects of various parameters on blood flow are discussed through graphs. It is observed that insertion of catheter increases the wall shear stress enormously depending upon the size of the catheter. Body acceleration enhances the axial velocity and flow rate. However it is found that with the application of slip velocity, the wall shear stress is significantly decreases
Stability of Multiwavelet Frames with Different Matrix Dilations and Matrix Translations
Get PDFIn this paper, we study the stability of multiwavelet frames with different matrix dilations and matrix translations by means of operator theory and show that these frames remain stable over some kinds of perturbations of the basic generators
The Underlying Physiology of Arterial Pulse Wave Morphology in Spatial Domain
Get PDFCardio-vascular events are among the world’s leading causes of morbidity and mortality. Most postulates suppose that culinary delights can be implicated in incidences of cardio-vascular diseases. This school of thought holds well in many respects. Much as the truistic value of the said school is acknowledged, we conceived of physiological disposition as an endogenous dominant factor in the events being considered, whereas culinary measures constitute an exogenous contributory factor. In this work we aimed at studying the effects of distance (stature) on pulse waveforms. Certain elements of our study showed that pulse wavelength was dominant in prescribing cardio-vascular physiology
Solvability of integral equations with endogenous delays
No full textThis paper performs a systematic study of some nonlinear integral equations with unknown lower limits of integration, which arise in economics, operations research, population biology and environmental sciences. A general investigation technique is developed for systems of such equations and several theorems about the existence and uniqueness of a solution are proven. The links to other functional equations with state-dependent delays are discussed. Applied interpretation of the obtained results is provided. © 2013 Springer Science+Business Media Dordrecht
