Bone density

Simple distillation was used for a liquid whose boiling points is 25 degrees Celsius over the other liquid, whereas fractional distillation is used for liquids with boiling points that are closer than 25 degrees Celsius apart. To obtain the highest percent ethanol, fraction distillation is proven to be the most effective. Because the 2 liquids have a boiling point difference of about 25 degrees Celsius, we used both simple and fractional distillation to remove the ethanol from the water.…

Experiment 1 Density By Jessica Schmidt Chem 112L-S23- Athukoralage Gunawardana September 20, 2016 Erin Whitehouse The first part of the experiment consisted of finding the accuracy and precision of three different measuring devices, a 50mL beaker, a 25mL graduated cylinder and a 25mL pipette. The mean volumes and uncertainties were found to be 22.5mL 1.9, 23.72 .25, and 24.89 .43, respectfully. The 25mL pipette was found to be the most accurate out of the three. The density of water was…

this experiment was to illustrate how to determine the density of a liquid and regulate volumetric glassware properly. To determine the mass of liquids using a scale, the density of water and (unknown) liquid D were weighed, inside of a volumetric flask. Once the mass was determined in grams, the density was easy to determine, by using the density equation. The second portion of this experiment was to calibrate a 10mL pipette. Once the density was determined for this section, the pipette…

A water table marks the top of the saturated zone of groundwater. When something is saturated, it means one substance (Like soil) is filled with another substance (Like water). Therefore, the area filled with water is called the saturated zone. This zone can be called the phreatic zone or the zone of saturation. This is always the zone below the water table. Directly above a water table there is always a capillary fringe. The water table separates the capillary fringe from the zone of saturation…

Lab two explored varies ways to find the density of objects. This lab used displacement , measurement, and the density formula to make observation and collect data about the balloon filled with sublimed dry ice, various water samples, and a golf ball. The ultimate goals of this experiment were to collect the most precise measurements of displacement of the balloon in the tap water, the weight of the three water samples versus the original cylinder, and diameter of the golf ball in order to use…

to determine the density of an unknown liquid. Additionally, the opposite process was used to determine the calibration of a piece of glassware using a known density. In the first activity, “Density of Liquids”, the identity of a liquid was determined by calculating its density (g/mL). First the mass (g) of a specific volume (mL) of water and the unknown liquid was found. Their densities (g/mL) were then calculated by dividing the mass (g) by the density), the calculated density was then…

Osteoporosis is a skeletal disorder characterised by low bone density weakening of bony tissue. When this occurs bones are more prone to fractures Bone loss happens without any symptoms that’s why some individuals might not know that they have osteoporosis until the bones are so weak and fragile. Women are affected by osteoporosis than men because women have lower dense bone mass and an increased rate of low bone mass especially after menopause. Primary osteoporosis is the most common type of…

Bone pathology involves understanding the causes and effects of bone diseases. Bones undergo a continual process of breakdown and renewal to maintain maximum bone strength. Healthy bones provide support and durability. Skeletal diseases of bone are often contributed to the severities of low bone density, mass, or deterred bone tissue. Osteoporosis is one of many bone diseases. Osteoporosis occurs when the formation of new bone doesn’t keep up with the elimination of old bone. It’s a…

x-ray absorptiometry, they found that in the trabecular sites such as the femoral metaphysis, tibial metaphysis, and the L5-6 vertebrae but not in the cortical sites. Using bone histomorphometry, microscopic changes were then looked at specifically in the tibial metaphysis. They found that there was a narrowing in new formed bones using a calcium chelating agent that fluoresces green. They also found that there was a marked loss of calcified tissue with marrow expansion in the tibial secondary…

rate of new bone made does not match the levels of bone being broken down. The condition is caused by a range of factors in which effects the levels of new bones made. There are a range of factors that cause Osteoporosis, these are Estrogen: If the level of estrogen drops then bone loss accelerates and can lead to Osteoporosis. Having both ovaries removed in a process known as bilateral oophorectomy, results in low bone density. In the case of males, testosterone is converted to bone-preserving…
