    LIMITATIONS OF VO2MAX INTRODUCTION The maximum volume of oxygen that the body can consume‚ transfer‚ or employ during a given exercise is called VO2max. This indicates the physical well-being of an individual. However‚ a multitude of physiological functions limit a person’s endurance for exercise by limiting maximum oxygen consumption by the body (Katch et al.‚ 2011). VO2max is used to determine the fitness levels‚ not only in athletes‚ but also in patients with heart failure‚ and is therefore

    microscopes‚ the observed transformation of the dynamic living organisms through growth and movement‚ the complex structures that they form/are formed in bring the research of an analogy between biology and from creation for designers. Arrangements of cells and atoms‚ their repeating patterns‚ the rhythms of their form forces architects to question the building components‚ just as Otto did by the inspiration of radiolarians. In a way to continue in the search of the effect of these self-generated dynamic

    Friction on a surface. Aim: To establish the relation between weight of a rectangular wooden block lying on a horizontal table and the minimum force required to just move it using a spring balance Materials required: A rectangular block of wood with a hook ‚ set of weights‚ strong thread and a spring balance. Theory: The force of friction acting on a block of wood is proportional to the normal reaction acting on the block. By the third law of motion‚ normal reaction is equal to the weight

    does surface area affect reaction speed? The aim of this experiment was to investigate how the surface area affects the rate of a reaction in between calcium carbonate and hydrochloric acid. My hypothesis was that if the surface area to volume ratio of calcium carbonate was increased‚ then the rate of the reaction will increase because there are more particles that are accessible by the hydrochloric acid‚ thus more particles that can react with each other. Variables Independent- Surface area

    Surface Tension My problem was to find out how to test or measure surface tension. I think the reason of some of the force in surface tension is cohesion and gravity. Surface Tension is the condition existing at the free surface of a liquid‚ resembling the properties of an elastic skin under tension. The tension is the result of intermolecular forces exerting an unbalanced inward pull on the individual surface molecules; this is reflected in the considerable curvature at those edges where the

    Essay: Cell Size Life is defined as a distinctive characteristic that a living organism‚ dead organism or non-living thing‚ and it has the ability to grow‚ metabolize‚ respond to stimuli‚ adapt and reproduce. Cells are not smaller that 0.1 um because within the cell all the necessary components have to take place‚ cellular metabolism‚ reproduction‚ photosynthesis and there has to be a sufficient amount of space for that to occur. Once you get to this tineness the machinery in this cell cannot

    Microsoft’s Surface Pro laptop-in-disguise1 tablet is no different‚ a “flawed”2 device which has seen improvements to its design and structure over the past few years making it slowly approach perfection. Microsoft’s Surface Pro is one of the newer innovative devices that was initially introduced in February 20133 and has seen a much shorter succession cycle than that of any other popular tablet manufacturer‚ namely Apple. Adoption rate was not at its best with the initial introduction of the Surface Pro
