Osmosis Lab Report The essential focus of the experiment was to acquire data for the mass change resulting from osmosis in order to determine the carbohydrate solution of the carrot cells. The carrots were a vegetable used within the experiment with a carbohydrate solution around .5 M. The hypothesis is if there are carrots in different carbohydrate solutions then there will be a percent change in mass. The carrots have large vacuoles that hold water‚ this allows the mass to increase when the hypertonic

Physical Chemistry CHM2330 Experiment F- Raoult ’s Law Experiment By: Sanah Assaad Student Number: 5267864 Partner: Jihad Arafa T.A: Didier University of Ottawa March 25‚ 2010 Objective: The purpose of this experiment is to study the total vapour pressure of ideal or non-ideal mixtures of two volatile liquids as a function of chemical composition. Introduction: For ideal mixtures of volatile liquids the vapour pressure of any given mixture may be obtained by applying Raoult

EXPERIMENT 201: WORK‚ ENERGY AND POWER John Michael A. Ramos‚ Phy11l/A5 Abstract The essential conditions to be satisfied for work to be done are: Some force must act on the object. The point of application of force must move in the direction of force. W = F x s. SI unit of work is joule. Energy is the capacity to do work. The two types of mechanical energy are kinetic energy and potential energy. Kinetic energy is the energy possessed by an object by virtue of its motion. Potential energy is

Experimental Design and Quasi- Experimental Design Cherry Spelock Ohio University An experimental study is defined by the way a researcher manipulates independent variables to prove or disprove a hypothesis. Outcomes are then measured and recorded. Experimental studies are considered one of the most valid ways of determining causal relationships (Byiers‚ Reichle‚ & Symons‚ 2012). When the independent variable cannot be controlled or other factors important to the study are out of the

EXPERIMENT 3: ISENTROPIC EXPANSION PROCESS Objective In order to demonstrate the isentropic expansion process. Introduction Isentropic means no change in entropy. Entropy is a thermodynamic property that is the measure of a system’s thermal energy per unit temperature that is unavailable for doing useful work. In simple terms‚ the measure of the level of disorder in a closed but changing system‚ a system in which energy can only be transferred in one direction from an ordered state to a disordered

355.2 Experiment 1: L2R algorithms for SDR The eight algorithms in Ranklib [62]: {MART‚ RankNet‚ RankBoost‚ AdaRank‚ Coordi- nate Ascent‚ LambdaMART‚ ListNet‚ Random Forests} are tested for optimizing one of each of the evaluation metrics {NDCG@10‚ ERR@10‚ MAS P}. Table 5.2 shows that all models built from learning to rank algorithms outperformed the baseline unsupervised BM25 score ranking in terms of the average of the evaluation measures used over the five folds: NDCG@10 (Equation (2.17))‚ ERR@10

In order to make yourself irreplaceable‚ you need to understand what your most valuable activities are. I’m going to walk you through a short process to help you discover them. To make this easier for you we’ve created a worksheet that you can use. In this worksheet the column called Work Activity is where you’ll list each type of work activity that you perform during the day. For this exercise‚ you want to separate these work activities in terms of the big picture rather than individual tasks. Work
