اصل و ترجمه مقاله لاتین Nutrition for the sprinter

Nutrition for the sprinter Abstract The primary roles for nutrition in sprints are for recovery from training and competition and influencing training adaptations. Sprint success is determined largely by the power-to-mass ratio, so sprinters aim to increase muscle mass and power. However, extra mass that does not increase power may be detrimental. Energy and protein intake are important for increasing muscle mass. If energy balance is maintained, increased mass and strength are possible on a ...

دانلود مقاله PtPb/PtNi Intermetallic Core/Atomic Layer Shell Octahedra for Efficient Oxygen Reduction Electrocatalysis

دسته بندی : مقاله های انگلیسی فایل : pdf زبان مقاله : انگلیسی تعداد صفحه : 8 رشته مقاله : شیمی نوع مقاله : علمی  مقدمه :Although explosive studies on pursuing high-performance Pt-based nanomaterials for the fuel cell reactions have been carried out, the combined controls of surface composition, exposed facet and interior structure of the catalyst remains formidable challenge. We demonstrate herein a facile chemical approach to realize a new class of intermetallic Pt-Pb-Ni octahedra f ...

اصل و ترجمه مقاله لاتین FORMULAS AND CHARTS FOR IMPEDANCES OF SURFACE AND EMBEDDED FOUNDATIONS

FORMULAS AND CHARTS FOR IMPEDANCES OF SURFACE AND EMBEDDED FOUNDATIONS   Abstract A complete set of algebraic formulas and dimensionless charts is presented for readily computing the dynamic stiffnesses (K) and damping coefficients (C) of foundations harmonically oscillating on/in a homogeneous half‐space. All possible modes of vibration, a realistic range of Poisson's ratios, and a practically sufficient range of oscillation frequencies are considered. The foundations have a rigid basema ...

اصل و ترجمه مقاله لاتین A MACRO-ELEMENT FOR DYNAMIC SOIL-STRUCTURE INTERACTION ANALYSES OF SHALLOW FOUNDATIONS

A MACRO-ELEMENT FOR DYNAMIC SOIL-STRUCTURE INTERACTION ANALYSES OF SHALLOW FOUNDATIONS Abstract  The scope of the paper is to present some aspects of the development of a "macro-element" for dynamic soil-structure interaction analyses of shallow foundations. Initially the concept of "macro-element" is introduced and is illustrated with the aid of a very simple example originating from structural engineering. Then the link is made with the modeling of the dynamic response of shallow foundat ...

اصل و ترجمه مقاله لاتین Soil-Structure Interaction for Building Structures - Chapter 2 :Inertial Interaction

Soil-Structure Interaction for Building Structures - Chapter 2 :Inertial Interaction Inertial interaction refers to displacements and rotations at the foundation level of a structure that result from inertia-driven forces such as base shear and moment. This chapter describes inertial soil-structure interaction effects. Inertial displacements and rotations can be a significant source of flexibility and energy dissipation in the soilstructure system. Section 2.1 discusses system behavior and high ...
