Security Incident Report Incident Report #: IR-783 Reported Date and Time: January 12, 2014 Technician: Max Smith Site Location: Sales Department laptop belonging to Howard Telmik. Windows 7 OS. Identification (Type and how detected): Howard in sales called the IT help desk complaining that his system is really slow. He also stated his laptop is behaving weird. Some of his internal reports have been modified and emails from last week have shown up as read. He knows he it wasn't him because

Henry Moreno Chem-201 Objective The objective of this lab experiment is to measure the material in the gas phase and to see how the ideal gas experiment could apply to the physical. In this the material we used was, a sip-lock plastic bag, a large plastic beaker, thermometry, dry ice, water, and butane lighter. Introduction In this lab, the experiment focused on the relationship between the temperature and pressure of an ideal gas that was dry ice inside the closed container. Therefore,

Data: See attached sheet Discussion: The catalase enzyme does not work at high temperatures around or above 50 degrees celsius. We proved this in our lab when the slope changed from 0.021 kPa/sec at 34 degrees celsius to negative 0.009 kPa/sec at 54 degrees celsius. With just a change in 20 degrees the slope, or how well the enzyme is working went from really good to really bad. The catalase enzyme works best around a pH of 10. At a pH of 4 and 7 the slopes were 0.007 and 0.009 kPa/sec. At the

Introduction In race carbohydrate is a key aspect to endurance performance, especially when the events lasts in extent of 1-2 hours. It is common practice within the endurance community to utilize carbohydrates as the substrate, as glycogen depletion is seen as a key mechanism in performance outcome[2,4, 14]. Providing exogenous carbohydrates into the body, in theory, spares endogenous carbohydrate reserves allowing for increased exercise time[5]. The current recommendation from the American College

Figure 3e shows the effect of temperature on the Q values of hydrogels after the pasting reaction. The Q values increased and then decreased with increasing temperature, and reached to the maximum at 50 °C. Less free radicals could be produced at such a low temperature, and thus may decrease the rate of grafting reaction, resulting in low Qs. With increasing temperature, more free radicals could be produced and the monomer reactivity may increase; therefore, the grafting and chain growth rate increased

In lab 7, Factors affecting Enzyme Activity, there are two parts; Effects of concentration on enzyme activity and effects of temperature on enzyme activity. In the first lab with concentration the materials needed to preform this experiment will be a LabQuest, Vernier O2 Gas Sensor, Nalgene bottle, enzyme suspension, 3.0% H2O2 , stop watch, goggles, three test tubes and dH2O and a 10 ml graduated cylinder.The first step in the procedure is to obtain three test tubes and label them 1, 2, and 3. With

When smaller monomers are linked together, they form larger polymers which are normally stronger and more durable. Dissolved in water, sodium borate acts as a binding agent when added to polyvinyl alcohol (PVA), cross-linking the polymers by reacting with the hydroxyl groups in PVA (Baker). When this cross-link occurs, it produces four molecules of water as a byproduct (Figure 1) (“Experiment 2”). Polyvinyl acetate (PVAc) is a rubbery polymer, capable of strong binding and flexibility (Dyslex). PVAc

In our lab today we separated into four different groups to prepare different types of quick breads. The quick breads we decided to make were popovers, muffins, biscuits, and different flour variations for both the muffins and biscuits. Before we began preparing these dishes, we discussed what needed to be prepared first and the proper way to prepare them for the short amount of time that we would have to work with. Working with instructions provided, each group was asked to prepare a variation of

Reflux is used to help carry a reaction to completion because the starting reagent has a slow reaction time. The purpose of reflux is to increase the reaction rate by boiling, but not to vaporize the products due to the low boiling points. The mixture of the starting material were heated first under reflux by increasing the rate of reaction through heating with a condenser attached because the temperature can be controlled while the condenser preserves the reagent by chilling the vapors. At the end

Objective: To demonstrate and explain muscle fatigue Variable Choices: Temperature (hot,neutral and cold) Background Information: The bones on the skeleton are caused to move by skeletal muscles. When muscles tend to contract it creates the ability of the joints to move and let us engage in physical activities. For muscles to contract, chemical energy is required. The chemical energy is a result of respiration. The skeletal muscle is made of two different kinds of fibers: slow twitch (ST)
