load frame with a wedge. The one in the lab was an MTS 647 Hydraulic Wedge Grip and an 810 Material Test System. The specimens had strain gages with a Wheatstone bridge to collect data such as time, distance, load, axial strain, and transverse strain in volts which was converted into pounds per force (lbf), pressure (psi), and etc. for data analysis. From the strain gages, evidence can support how and when the specimen material failed under the stress being applied to the specimen. The test…

Figure (4.3): Failure pattern of cubes specimens (C1). 4.2.3. Static Modulus of Elasticity: Modulus of elasticity is a necessary parameter to determine the stresses in materials and structures. Even though concrete has nonlinear stress-strain behavior,…

information through a process of transformation. He began isolating two strain of Streptococcus pneumonia, the S strain and the R strain that varied dramatically in both appearances and their ability to cause diseases. Specifically, the highly virulent S strain has a smooth capsule, the outer coat composed…

carbons, it ideally exists with 109.5-degree bond angles. If cyclohexane were planar, it would be forced to have 120-degree angels, and would therefore have angle strain. However, cyclohexane chair conformations are almost completely free of angle strain due to their 111-degree bond angles. Planar cyclohexane would have substantial torsional strain, because each of its carbon-carbon bonds would be fully eclipsed. In contrast, each of chair cyclohexane’s C-C bonds is staggered, meaning there is…

Mutation on the three Stages of Cellular Respiration Mary A Enriquez University of the Pacific November 11, 2014 2 Green Dr. Geoffrey Lin-Cereghino Abstract: The purpose of this lab is to determine which type of food source could possibly help strains grow on both permissive and restrictive temperature. Based on all the chemicals accumulating, we can determine the enzymes that are used to inhibit the three stages of cellular respiration. Introduction: For cells to successfully…

behind this experiment was to check whether rhesus monkey cells are more effective against the HSV-1 and HSV-2 replication than Human TRIM5. Rhesus Macaque fibroblast cell lines and HeLa cell lines were infected with HSV-1 KOS and HSV-2 186 syn+ strains at MOI=3 PFU/cell and harvested at different time points post infection. The viral load at these time points are shown the Figure 1. From the figure we understand that the viral yield from the rhesus monkey cells is almost 100 fold less than the…

there are many strains that aid in different ways by causing a different effect on the body. For example, you may notice that a certain strain causes more of a sleepy response, while another may cause you to be more alert. In a similar way, different strains can help in different ways. Arthritis Many strains offer the benefit of pain relief, which is another reason that marijuana has proven beneficial to those battling cancer and associated pains. However, there are some strains that thrive in…

Ventricular Function Assessment in Single LAD lesion Patients Using Strain and Strain Rate Imaging Abstract Background. Strain and strain rate imaging is currently the most popular echocardiographic technique that reveals subclinical myocardial damage, no available data on this imaging method with regard to assessing right ventricular involvement in single LAD lesion. Aim. to evaluate right ventricular regional functions using strain and strain rate imaging tissue Doppler method in…

The American television network Investigation Discovery airs a television series called “A Crime to Remember”, which shows the most compelling crimes of the past in United States history. In the televisions first season, it aired an episode titled “A New Kind of Monster”, and in this episode it reacted a series of murders between 1967-1969 of young females from Eastern Michigan University. The murder of all the victims name is John Norman Collins also known as “The Co Ed Killer”. John Norman…
