Introduction The engineering case studies presented in the fictional video provides profoundly different sets of ethical issues that are presented at various manufacturing companies that want to put up hurriedly manufacturing chemical plants. Engineering profession, just like in many other professions is confronted with many ethical responsibilities. The study is exceptionally important to the practicing engineers since it presents viewers with ethical guidelines that should be followed when…

Introduction: Wind chill is the measure of the combined effect of wind and lowering temperatures on beings (Steadman, R. G. 1971). With wind chill animals would be cold especially during winter months with the harsh winds, because of this out in the environment animals have fur coats to help them hold and retain heat against the wind. The way animal is able to retain heat is due to thermal physiology designed to keep a being warm by preventing heat from leaving the body (Media 2014). An analysis…

Lithium is an element with the atomic number 3 on the periodic table. Its atomic symbol is Li. Lithium belongs in the most reactive group on the periodic table which is called alkali metal. Lithium under standard conditions is the lightest metal it is also one of the least dense solids. Lithium has an atomic mass of 6.94 and density of 0.534. Lithium is a soft silver white looking metal. Lithium melts at 357 degrees and boils at a temper of 2426 degrees. Thanks to lithium's ability to reach…

iv. Increased enzymatic capacities for substrate catabolism v. Higher degree of clustering of subsarcolemmal mitochondria adjacent to capillaries-> higher O2 flux rates vi. Mitochondrial volume densities and surface areas per unit mitochondrial volume are near maximum theoretical limits in hummingbirds and higher than mammals-> achieved due to higher oxygen delivery capacities and substrate catabolism (Suarez et al. 1991) 5. Metabolic Substrate Turnover a. Questions i. Do hummingbirds…

The corneal endothelium is metabolically highly active, and accordingly, endowed with a large number of mitochondria (**). Recent studies have claimed mitochondrial dysfunction in response to deliberate oxidative stress and in FECD (**). Although mitochondrial damage is correlated to cell death, its effects could be more subtle when the damage to the organelle is not severe. Specifically, when mitochondrial damage is not severe, the cellular functions could be impacted by ATP depletion. The…

Obtain a piece of paper that is approximately 5cm x 10cm, and tear it into small fragments. Place the pieces of paper on a watch glass, and light the paper with a match. Observe and record reactions. Deposit a microspatula of NaCL (sodium chloride) into a test tube, and dilute the substance by infiltrating approximately an inch of water to the test tube. Let the NaCL dissolve into the water by shaking the test tube with one’s thumb over the opening of the test tube. Using a dropper, place…

Lithium is the chemical element of atomic number 3, a soft silver-white metal. It is the lightest of the alkali metals. The two main parts of every atom are neutrons and protons. The three main subatomic particles that form an atom are protons, neutrons, and electrons. Electrons are the smallest of the three particles that make up atoms. Electrons are found in shells or orbitals that surround the nucleus of an atom. Protons and neutrons are found in the nucleus. They group together in the center…

The purpose of this experiment was to determine the thermodynamic properties of the entropy, enthalpy and free energy, as well as the solubility product of borax as a function of temperature from the dissolution of borax in an aqueous solution. Thermodynamics is the study of heat and its transformations. The properties of thermodynamics are entropy, enthalpy and free energy. The properties of thermodynamics can be viewed in terms of spontaneity. Spontaneity is a spontaneous change of a system…

M & M Three oranges were cut in half and then placed over the juicer. The oranges were then pressed down, while being twisted allowing the juices from the oranges to be collected in the tray below. The orange juice in the trays were then poured into a 250ml beaker with cheese cloth on top of it. The cheesecloth caught the larger pieces of pulp from the oranges while allowing the juice to pass. The orange juice was then transferred into six 1.5ml centrifuge tubes. The six centrifuge were then…

This experiment exemplifies the effects of the concentration of hydrogen on the strength of bone. As bone is majorly composed of calcium, and knowing that acids want to neutralize. Throughout the experiment, results show that the strength of the bone was compromised in acidic situations, but rather unaffected in situations where the concentration of hydrogen was basic. Even more noticeable than the change in pure tensile strength is the change in the maximum deflection before fracture.…
