Introduction A can opener is a kitchen utensil used to open canned goods. A manual can opener has four parts: the handles‚ the crank‚ the traction gear‚ and the cutting wheel. These parts are found only on a manual can opener. Handles The body of a manual can opener consists of two handles connected with a single bolt‚ allowing them to be pulled apart and pushed together. Higher-quality can openers have rubber grips on the handles‚ making them easier and more comfortable to grip. Traction Gear

1a. Two reasons that the mass of the bag levels off with time include (1) equilibrium and (2) hydrostatic pressure. Equilibrium refers to the concentrations becoming equal. If there is no longer a higher concentration and lower concentration between the water and sucrose‚ osmosis can no longer take place. Osmosis can only occur when water is traveling from a higher concentrated area to a lower concentrated area. Hydrostatic pressure occurs when the bag reaches maximum capacity. Water will enter the

Toxicology Lab 1. In this investigation‚ a wide range of concentrations of Sodium Chloride (NaCl) solution were created and the effects that they had on radish seeds were tested. This ultimately created a doseresponse experiment in which it was detectable whether or not radish seeds were a reliable bioassay for the toxicity of NaCl. The goal of this experiment was to determine a correlation between toxicity and seed germination/radicle

Basic Mechanism An autoimmune disease occurs when the body produces an abnormal immune response against self antigens. It is caused by failure of the tolerance processes to protect the host from the action of self reactive lymphocytes. An organ-specific autoimmune disease involves gradual damage to cellular structures and is replaced by the compensating connective tissue which depletes the function of the gland/organ. Type 1 diabetes (TD1)‚ is an organ specific autoimmune disease characterize

Lab 5 The Diffraction Grating Chinua McDonald Objective: To measure the wavelength of light with a diffraction grating. Theory: The two types of diffraction gratings are the transmission and reflection gratings. They are made by ruling on a piece of glass or metal a number of evenly spaced lines with a fine diamond point. Diffraction phenomena can be analyzed in terms of Huygens’ principle‚ according to which every point on the wave front of a wave should be considered as a source

There are four mechanisms of unfreezing stage. Disconfirmation ; information disproves the assumptions and makes need for change obvious. Looking at the current situation and seeing it is not satisfying. People feel frustration and dissatisfaction. Nurses don’t use translators efficiently and having hard times with assessing patients. This is just unacceptable. Lack of confirmation; no information forthcoming to validate assumptions- it dawns on person slowly that the change is needed. Nurses still

indicated by a very pale pink color. To calculate the molarity of NaOH‚ the following equation was used MNaOH x VNaOH = MKHP x VKHP therefore the molarity was .125 M. INTRODUCTION This lab experiment covers the preparation of standard solution and the acid/base titration. The first part of the lab is to prepare a standard solution of Potassium hydrogen per. A standard solution is a solution of known concentration‚ in which it is prepared using exacting techniques to make sure that the molarity

two of these cases: SN1 and SN2. Many other reactions in this class proceed by mechanisms that are best described as somewhat between the two extremes. The SN2 reaction occurs in a single step. The nucleophile simultaneously attaches to the substrate as the leaving group leaves. The reaction displays second-order kinetics; its rate is proportional to the concentrations of the both the substrate and the nucleophile. In a SN1 reaction‚ the first step is departure of the leaving group from the

of analysis‚ namely Phonetics‚ Phonology‚ Morphology‚ Syntax and Semantics. The writer will dwell on the airstream mechanisms involved in Phonetics‚ which is the study of sound and speech production in human language. The word ‘airstream’ refers to a current of air; specifically ‘airflow’. The method by which airflow is created in the vocal tract is called airstream mechanism. Encyclopedia Britanica Dictionary (2010). The organ that generates the airstream is called the initiator and the production
