lead to quantifiable changes in a stroke patient’s lung volumes and lung capacities, including having a higher residual volume (RV), decreased lung capacity (18), decreased peak expiratory cough flow rate (PECF) (4, 19), and decreased maximal inspiratory and expiratory pressures (MIP and MEP, respectively) (20). Stroke patients can also have decreased forced vital capacities (FVC), forced expiratory volumes in one second (FEV1), and tidal volumes (TV) (16). These negative changes in respiratory
Title: Measuring the vital capacity and total lung capacity on human lungs Objectives: To investigate the effect of gender on vital capacity and total lung capacity on human lungs. To develop problem solving and experimental skills, for example, information is accurately processed and presented, experimental procedures are planned, designed and evaluated properly, producing valid results, recording results, and a valid conclusion is drawn. To develop techniques of using a portable spirometer
To improve your body, biomechanics is unavoidable. Biomechanics is the branch of kinesiology that seeks to understand the behaviour and function of the living human body when it is acted upon by forces. “With the use of biomechanical analysis atletes are able to use to use visual feedback in order to identify both positive and negative aspects of their technique (Shackel 2)”. To advance the body stability is one of the seven principles of biomechanical analysis required. Stability is the lower the
two different sized cylinders. Accuracy is a measure of how close something is to its true value. To determine the accuracy we had to measure the volume and compare it to the theoretical volume, finding the relative error. Following this we used the density of water, 0.99720 g/mL, along with the mass we determined with a scale, to determine the volume of water in a 10 mL pipet using the formula D=mv. Objective: The purpose of this lab is to determine which cylinder, the 10mL or 100mL is will produce
Expansion and Contraction of Materials When most materials are heated they expand and this increase their volume. One example of expansion is the fitting of the starter ring gear to the flywheel. The gear is heated until it expands sufficiently to pass over the rim of the flywheel, and when it is cool the gear tries to return to its original size, this gripping the flywheel with considerable force. All metals do not expand equally when heated through the same range of temperature, e.g. aluminium
below this it shouldn't be a problem. Method: To perform the titration the first thing that needs to be done is to dilute the HCl to a suitable concentration, to increase the accuracy of the results it would be helpful if the volume of the alkali equalled the volume of the acid used. We know that the concentration of the alkali is close to 1g/dm‾, which is roughly equal to 0.013mol by using the equation Mass = Mole * RAM.
determined that the best way to conduct this experiment is to do a titration. This will allow me to determine the amount of impure citric acid required to neutralise a known volume of 1.0 M sodium hydroxide. Consequently, by calculating the correct volume of pure citric acid that would be required to neutralise this volume of sodium hydroxide, I can calculate the percentage purity of the citric acid. Calculating the Amount of Citric Acid ------------------------------------- In order
this activity is to determine the size of the square cut out which makes the volume of the box as large as possible for any given rectangular sheet of card. 1. For any sized square sheet of card, investigate the size of the cut out square which makes an open box of the largest volume. 2. For any sized rectangular sheet of card, investigate the size of the cut out square which makes an open box of the largest volume. Question 1 ---------- I began work on question 1, which was to investigate
Measuring the Viscosity of a Liquid Aim The aim of this experiment is to find out how fluid Bath Oils really are by measuring its viscosity. Plan The first thing that I'll do is to measure the spheres volume by first measuring its radius. I will then, by calculating the spheres mass, be able to calculate the density of the sphere. This will be used later when calculating the viscosity of the bath oil. I will then find the density of the bath oil, also used during calculations later

the volume of amylase affects the rate of reaction between amylase and starch. Prediction: I predict that the greater the volume of amylase then the faster the rate of reaction between the starch and amylase will be. I predict this because of the lock and key hypothesis. The lock and key hypothesis explains how the substrate molecule (the starch) fits inside the enzyme. The substrate molecule is then broken up into many smaller pieces. In this experiment the larger the volume of amylase
Students can get the formulas and example problems in online. In this article we shall see how to calculate the volume and surface area of three dimensional shapes. Online 3 dimensional shapes lesson help – Formulas: Cube: cube Volume of the cube (v) = a3 cubic units a – side length Surface area of cube (SA) = 6a2 square units a – side length Cylinder: cylinder The volume of the cylinder (v) = π x r2 x h cubic unit r – Radius of cylinder h – Height Surface area of right
pressure and volume of a gas, which is now known as, Boyle’s Law. Boyle’s law states a volume of gas varies inversely proportional to its pressure at a constant temperature. The equation for Boyle’s law is written as P1 X V1 = P2 X V2 (Jardins 2013), which is used to calculate the settings on ventilators and other respiratory machines. For patients on ventilators this is one of the ways they can get help when they can’t breathe for themselves and need to get oxygen into the lungs. It also removes
Finding the Hidden Faces of a Cube In order to find the number of hidden faces when eight cubes are placed on a table, in a row, I counted the total amount of faces (6%8), which added up to 48. I then counted the amount of visible faces (26) and subtracted it off the total amount of faces (48-26). This added up to 22 hidden sides. I then had to investigate the number of hidden faces for other rows of cubes. I started by drawing out the outcomes for the first nine rows of cubes (below):

Mary Shelly incessantly portrays science and nature. At first Mary shelly illustrate the nature of life as distressing, sorrowful and frail. She does this by demonstrating illnesses, deaths and sorrow of the loved ones leaving and diseases. By doing this Mary shelly is representing life as a pathetic
written above Tintern Abbey', the concluding statement of the 1798 volume. The poem reads rather like the recitation of a liturgy. Wordsworth recollects his own faith by restating it, and in doing so he discovers its truth and its guarantee of continuity: "in this moment there is life and food / For future years" (ll. 65-6). However sceptical readers have become about the Wordsworthian-Coleridgean creed, the monumental quality of the volume is not entirely a figment of a literary history in search of Great

into three volumes, each taking place at a distinct time. Volume I highlights the correspondence in letters between Robert Walton, an Arctic seafarer, and his sister, Margaret Saville. Walton's letters to Margaret basically explain his expedition at sea and introduce Victor Frankenstein, the protagonist of the novel. Volume II is essentially Frankenstein's narrative, told in his point of view, with much action, death, and many more characters. There are a few chapters within this volume in which the
