Constraints are an important to the self-organization of human movements. There are three main categories of constraints. The categories are, individual, task, and environment. Together these three categories help us understand how coordinated movements are performed. Environmental constraints are physical variables that occur in nature. For curling this can be the amount of ambient light that the venue has. Environmental constraints can also be social, instead of physical. An example would be…

Osmosis Research Question What will happen to the length and mass of the potato when it is put in water and different concentrations of salt? Introduction Osmosis is the diffusion of water molecules from a region of higher concentration to a lower concentration of water molecules (through a partially permeable membrane). If the cell is placed in a higher water potential, water enters by osmosis and if the cell is placed in lower water potential, then the water leaves the cell by osmosis. The…

The simple integral desorption model was used to represent the physical phenomena of the extraction process.20 The extraction vessel is loaded with leaf particles with an initial andrographolide concentration of S0 (g/g leaf particles) to form a packed bed system. Fresh supercritical solvent is fed in to the bed, the pore and void volumes () are initially free of solute, and the process is isothermal. The total mass balance in the supercritical fluid phase of this system can be described by the…

Solubility of Chemical Compounds Lab Victoria Chanderpaul Tasneem, Zarrin Ms. Rungee February 6, 2018 February 13, 2018 Reaction of Chemical Compounds When Added to Water Introduction/Purpose: The purpose of this lab was to gain an understanding of how different chemical compounds react when added to water. Hypothesis: If different pure substances are dissolved in water, then there can be an understanding of the difference between the solubility because each chemical compound have…

3.0 RESULTS AND DISCUSSION 3.1: Effect of Storage Conditions on Egg Weight Tables 1- 2 show the results of effect of storage conditions on eggs weight (chicken eggs and quail eggs). The weight of chicken eggs stored at ambient condition (control), moist sawdust, refrigerator and those that were dipped in oil reduced from 63.61-60.03g, 63.11-60.99g, 61.12-59.41g and 66.12-65.79g respectively. While the weight of quail eggs stored at ambient condition (control), moist sawdust, refrigerator and…

FTIR Spectroscopic Study on Inner Membrane of Egg Shell of Chicken Gallus gallus domesticus Abstract: The paper presents FTIR analysis of inner membrane of eggshell of chicken Gallus gallus domesticus. Fresh samples of egg shells are cleaned; dried and inner membrane of the shell is separated carefully for FTIR analysis. FTIR spectrum reveals a series of bands related to fats and proteins. Calcium carbonate is the major constituent (about 90%) of the shell, but it is absent in the inner shell…

General Introduction Dietary lipids: Dietary lipids consist of a broad group of compounds that are soluble in organic solvents and insoluble in water. Their density is lower than water and consistency varies from liquids to solids at normal room temperature, depending on their structure and function. They are also referred as ‘Oils’ which are liquid and ‘fats’ which are solid at room temperature. Lipids are the important constituents of diet due to their higher energy value. One gram of lipid…

In this lab we wanted to identify what the four mystery liquids were using density and their characteristic properties. We were initially given four liquids that were labelled numbers 1- 4, some graduated cylinders, and a scale, but we also knew that the 4 liquids were ethanol, vegetable oil, water, and cyclohexane. Using the mass that we found when we measured the liquid and using only 10 mL of the liquids we were able to calculate the density and easily identify the liquids and see if they…

Emma Kilgore Science Period 2 January 12, 2016 The Evaporation of Liquids When a liquid is left in a warm car over a certain period of time some people might notice that the liquid seems to have lessened. This is because of evaporation, evaporation is when a liquid changes into a gas because of an increase in temperature or pressure. This brings up many questions having to do with liquids and evaporation so, do all liquids take the same amount of time to evaporate?…

My partner and I decided to discuss how understanding the concept of pillow method could affect our relationships with our peers. The pillow method works by breaking down a problem or argument into the 5 different perspectives. Understanding all of these perspectives can be valuable insight into resolving the problem and developing empathy, feelings that a person shares with others. Jordan described an argument with his sister in which his sister believes that ketchup tastes better than mustard…
