MEMORIAL UNIVERSITY OF NEWFOUNDLAND FACULTY OF ENGINEERING AND APPLIED SCIENCE Engineering: 4312 Mechanics of Solids I Lab Test #4 – Torsion Test OBJECTIVES: To carry out a torsion test to destruction in order to determine for a 1020 carbon steel rod specimen: 1. The modulus of rigidity‚ 2. The shear stress at the limit of proportionality‚ 3. The general characteristics of the torque‚ angle of twist relationship. REFERENCES: 1. Hibbeler‚ R. C.

VO2 Max Test Objective of the test: To work out how much oxygen can be utilized during an intense exercise test‚ the maximum capacity of oxygen used in the body Background of the test: The aim of this study was to create and evaluate a submaximal cycle ergometry test based on change in heart rate ( HR) between a lower standard work rate and an individually chosen higher work rate. In a mixed population ( n = 143) with regard to sex (55% women)‚ age (21-65 years)‚ and activity status (inactive to

3.7.2.1.5 Urea test PRINCIPLE Urea is hydrolyzed in the presence of urease to produce ammonia and CO2. The ammonia produced combines with 2 – oxoglutarate and NADH in the presence of GLDH to yield glutamate and NAD. Urea + H2O + 2H+ 2NH4+ + CO2 NH4+ + 2-Oxoglutarate +NADH H2O +NAD+ + Glutamate The decrease in absorbance due to the decrease of NADH concentration in unit time is proportional to the urea concentration.

Zebrafish Embryotoxicity Test (ZET) The ZET will be done following the method proposed by Beekhuijzen et al. (2015) with modifications. Six embryos will be exposed to each of the following treatments: 0.1‚ 0.05‚ 0.025‚ 0.0125‚ and 0.00625 mg/ml. Embryos will be incubated in 24-well plates with built-in lids. Each well will contain one embryo and 2 ml of the respective treatment. All test solutions will be renewed every 24h to maintain the integrity of the test concentrations. The embryos will

Cold pressor test is widely used as test for auto- nomic functions. It has been used as diagnostic test for diseases like hypertension and other cardiac auto- nomic disorders. During cold pressor test ‚ the hand or foot is immersed in cold water bath held at a con- stant temperature at 80 C. Cold water immersion activates afferent pain and temperature neurons‚ re- sulting in a centrally mediated stimulation of sympa- thetic efferent neurons. In healthy subjects ‚ the CPT causes increase

As a result of the tests ran‚ I was able to identify the unknown bacteria. For Unknown A‚ I ran six tests. I first isolated the bacterium from the second bacterium and found a clear growth (Table 1‚ Figure 1). Secondly‚ I ran a gram stain and found a gram positive‚ cocci bacterium (Table 1‚ Figure 2). Third‚ I ran a catalase test in which was negative (Table 1). From here‚ I determined a starch hydrolysis test would be necessary to distinguish between different bacteria. The result was negative (Table

1. Both of the subjects in this test preformed excellent compared to the rankings provided. Victors Mean Power put him in between the 85 to 90 percentile with his score of 639.83 and his Anaerobic Capacity put him in between the 60 to 65 percentile. These scores indicate that Victor trains more with resistance than aerobic type exercises because of the high score of his Mean Power. These scores also correlate with his VO2 Max test we preformed earlier. His VO2 Max of 3.4 is low compared to the high
