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

Blood pressure is defined as the force of flow of blood inside the blood vessels. This measure is reported as two numbers such as 130/180 mm Hg. The first number is called systolic pressure and measures the push of the blood through the vessels as the heart beats. The second number called the diastolic pressure and measures pressure in between heartbeats or when the blood vessels relax. High blood pressure is one of the most commonly associated medical conditions with diabetes. US statistics reveal

BOURDON TUBE PRESSURE GAUGE Bourdon Tubes are known for its very high range of differential pressure measurement in the range of almost 100‚000 psi (700 MPa). It is an elastic type pressure transducer. The device was invented by Eugene Bourdon in the year 1849. The basic idea behind the device is that‚ cross-sectional tubing when deformed in any way will tend to regain its circular form under the action of pressure. The bourdon pressure gauges used today have a slight elliptical cross-section and

If your pressure washer turns off after it been running for less than a minute‚ there are a few different parts on your pressure washer that may be causing the issue. Here is a quick breakdown of the top three things that could be causing your pressure washer to turn off after it has only been on for a few seconds. #1 Carburetor The first thing that you need to check is your carburetor.

Pressure ulcers may be an important issue of skin. It is an open wound in the skin and it may be called sore. However‚ it is more common in older due to the immobility. Although‚ there are other reasons other than immobility that may cause pressure ulcers like caused by shear or friction (Moon‚ 2012). Nutrition also plays a part in this‚ as not having the requirement nutrition the body needs to put the patient at a high risk for pressure ulcers (Mayo Clinic Staff). Also‚ having a certain medical

12 Pressure/Volume of Air Full Lab Write Up Introduction: According to Boyle’s Law‚ the volume of any given amount of gas held at a constant temperature varies inversely with the applied pressure. In other words‚ when the pressure increases the volume decreases. When pressure decreases‚ volume increases. This can be derived from the following equation: P1 V1=P2 V2 The common use of this equation is to predict how a change in pressure or volume will alter the volume/pressure of the

Hypertension is high blood pressure. This is a condition that has taken place from your external environment. For example‚ you may be under stress at your job or school. The stress can be very demanding and causes several things to happen to your body. The blood is pressured against the wall of your blood vessels causing your heart to beat faster and harder. This causes an increase in your pressure and now your normal functioning of your blood pressure is now disturbed or out of balance. The organ
