Q-1. Describe the function of hemoglobin in blood and describe how pH can affect the function of hemoglobin and the amount of oxygen in blood. Be sure to relate the lab results you obtained to this discussion. Hemoglobin’s main function is to carry oxygen throughout the human body. As the oxygen molecule is dissolved in the blood it combines with hemoglobin forming oxyhemoglobin. Oxygen released from oxyhemoglobin increases as the blood pH levels decreases. Deoxyhemoglobin can also bind to the…

include: • Coronary artery disease • Heart valve disease • High blood pressure • Hypertension • Valve conditions • Cardiomyopathy • Diabetes • Alcohol abuse • Smoking Coronary artery disease, also known as ischaemic heart disease, results from the gradual blocking of the coronary artery by fatty deposits called plaque. The coronary artery is the artery that supplies blood to the heart, damaging it…

C.E. 2.2 The meeting was held in the client’s office and we discussed in detail what their requirements are and how I can offer them the solutions. From the discussion with the hospital management and engineers, I determined that they are mainly concerned about three factors: 1. Bacteria development in the taps/mixers, 2. Patients health and hygiene 3. Water efficiency. I asked for a general layout as well as the plumbing and piping layout or plan for the hospital building to check all the areas…

not only rotate the camshafts, but also required to control the opening and closing of the valves, and the movement of the pistons. For the international combustion engine, there are two main solutions: teethed belt and chain. The crucial function of the timing drive system is to provide drive to the engine’s camshaft(s) and a constant timing relationship to the crankshaft in order to provide the correct valve opening and closing timing required for the engine 's thermodynamic cycle. [11] The…

ABSTRACT Within this experiment, the use of a bomb calorimeter was required in order to determine the heat capacity of the system through the combustion of three separate trials of benzoic acid. The resulting heat capacity values for each trial were averaged, with a standard deviation found as well. This was then used to work backwards, for a naphthalene trial, in order to calculate the change in energy (∆U) and the change of enthalpy (∆H). The accepted value for the change in enthalpy of…

The best defense against this is to locate and practice manipulating the shut-off valve to your home. However, while most people would naturally move to the indoor shut-off valve for this, it's not recommended. Instead, consider utilizing the valve outside of your home next to the water meter. You'll need to purchase a meter key to do this, but the valve is much more reliable for this purpose than the indoor valve. It's also extremely easy to locate. You'll just need to determine where you'll…

kidneys also produce erythorpoietin, renin and a form of vitamin D. Childhood renal diseases are categorized das either congenital or acquired. Congenital renal diseases such as Multicystic Kidney Disease, Polycystic Kidney Disease, Posterior urethral valve obstruction, and Fetal hydronephrosis can be detected during antenatal testing or postnatal examinations. Hydronephrosis is a sign of renal disease, in which the one or both kidneys retains fluid. Acquired renal diseases such as, nephritis,…

Chapter 3 Process description and modeling 3.1 Process Description of Propylene Glycol Production Process The physical properties of propylene glycol are colourless and clear syrupy liquid when exists at room temperature. Besides than in liquid form, it also may exists in vapor form in air. In order to produce a colourless and odourless chemical, propylene glycol (C3H8O2, PG) involve in the reaction of propylene oxide and water. This involve the process of the hydrolysis of propylene oxide…

The Schlieren photographs taken in this lab, attached in Appendix B, show how the flow develops with respect to the flow exit pressure that is controlled by the opening of the valve. Schlieren photography is made possible by the variation of refraction index of gases in different density. To be more specific, the Schlieren photographs are taken in an environment with a collimated light. Without external interference, a collimated light should propagate in parallel for an infinite distance;…

were recorded. The temperature selector was then switched to T2. A temperature close to room temperature should be shown. The throttle valve was then opened quickly. The temperature was monitored and the maximum value was recorded as…
