truss becomes internally statically indeterminate. In this case the truss is termed statically overdeterminate. The SE 110.22 experimental set-up permits investigation and comparison of statically determinate and statically indeterminate trusses. Using the bars and node discs‚ a statically determinate‚ single plane truss is first constructed. On installation of a surplus bar the truss becomes overdeterminate. By way of a load application device‚ straight or inclined forces are applied to the truss

ventricular contraction. We measure blood pressure using a sphygmomanometer and a stethoscope. To measure the systolic pressure‚ place the blood pressure cuff on the upper arm and inflate the cuff until blood flow in the brachial artery is stopped. Then we slowly release the pressure of the cuff until the systolic pressure in the artery is greater than the pressure of the cuff‚ which causes a tapping sound heard through

Biofuel Enzyme Kit Katie Adamson Biochemistry Laboratory‚ BIO124L 1/29/15 Abstract The objective in this lab was to determine the effects different conditions had on the enzyme cellobiase. We examined reaction rates in the presence or absence of an enzyme‚ the effects temperature and pH changes on the enzyme and the effects enzyme concentration and substrate concentration had on the enzyme. As expected results showed us that cellobiase works optimally when conditions are favorable. We see this

December 8‚ 2013 Soil Analysis Lab Report Intro: Soil is produced over hundreds of years through the weathering of rocks and the decomposition of organic material. Soil contains nutrients that are taken from decomposed animals and plants which turn to detritus. Nutrients such as nitrogen are added to the soil in these ways by organisms such as nitrogen fixing bacteria. Soil is important because it is the fuel to the plants that we need in order to survive and for all species to survive. Soil

University of Texas at Tyler Lab 3C: Purification of L-Lactate Dehydrogenase By Affinity Chromatography on Cibacron-Blue Sepharose David Alexander 10-15-2014 Dr. Black Chem 4135.001 Abstract: Like the previous experiments‚ the ultimate goal of this lab was to purify the enzyme sample. However‚ this is the last lab for purification and high level techniques of purification were employed to achieve this. Dialysis was used first‚ lowering the small-molecule concentration within the sample. Finally

For this lab‚ the expected outcomes are that when the heart rate and blood pressure are measured‚ both will increase when the heart has to pump against gravity‚ after exercise the heart rate will increase then return to normal‚ and as the subject inhales‚ it will be lower than when they exhale. Methods For this lab report‚ the laboratory manual (2009) was used for all labs. While completing lab five‚ electrodes were hooked up to the subject. After calibration for this lab‚
