by a low bone density and alterations in bone microarchitecture‚ responsible for the exaggerated bone fragility therefore‚ for a high risk of fracture. Biomechanical studies show that bone mineral density (BMD) is the essential factor for bone fragility. Fractures are signs of complications and seriousness of the disease. Currently‚ the diagnosis of the disease can be done before the first fracture with the BMD and examination of risk factors (Kelman &Lane‚ 2005) Pathophysiology Bone is constantly

Zinc in Pennies from Density Lab Report Procedure: For pre-1982 pennies- Mass 10 pennies‚ record data. Fill a 100mL graduated cylinder to 40mL or enough to fully submerge the pennies with water‚ record the volume in data table. Carefully place the pennies into the graduated cylinder‚ record the final volume of the water in data table. To find the volume of the pennies‚ subtract the final volume from the initial‚ record the data. Repeat this procedure twice more. Use the density formula to calculate

Osteoporosis is a metabolic condition that is slow and progressive and leads to decreased bone mass. This disease is usually found in the elderly but can present in postmenopausal and estrogen-deficient women (Colbert‚ Ankney & Lee‚ 2013). Osteoporosis can affect any bone in the body but most commonly affects the hips and spine. The decreased bone mass causes weak bones which leads to fractures. Fractures in elderly patients with Osteoporosis can occur from normal activities such as walking and

The Density of a material may be determined by determining the mass and volume of a sample material and calculating the mass/volume ratio. An independent variable is the variable that is being manipulated or changed during the experiment. The dependent variable is the variable that is being measured. The independent variable for this experiment is the copper because you are only changing the amount of copper you use. The dependent variable is the density because we are measuring the density. In

are the density‚ relative error and the standard deviation. Density is refers to the mass (m) per unit volume (V) of a material and is often represented by the symbols d or ρ‚ where d = m/V. The density of an object changes with pressure and temperature. Second‚ relative error is a calculated by finding the difference between the true and measured values and dividing this difference by the true answer. And‚ the standard deviation is the measure of the spread of dispersion of scores (density) from the

Apparatus INTRODUCTION Density is defined as mass per unit volume. The commonly used unit to indicate the density of water is (g/cm3). Water never has an absolute density because its density varies with temperature. Water has its maximum density of 1 g/cm3 at 4oC. When the temperature changes from either greater or less than 4oC‚ the density will become less than 1g/cm3 only when it is pure water. Other factors that can affect water’s density whether it is tap water‚ fresh water or

3.6 cm high‚ 4.21 cm long‚ and 1.17 cm wide. If the mass is 21.3 g‚ what is this substance’s density (in grams per milliliter)? * Volume= 3.6*4.21*1.17= 17.7g * Density= mass/volume= 21.3/17.7= 1.2g/mL * Density= 1.2g/mL D. A sample of gold (Au) has a mass of 26.15 g. Given that the theoretical density is 19.30 g/ml‚ what is the volume of the gold sample? * Volume= mass/density= 26.15/19.30= 1.35mL * Volume= 1.35mL E.

Lab Report: DRILLING FLUID (MUD) DENSITY Objective: The aim of this experiment is to determine the mud density‚ specific gravity and hydrostatic pressure gradient for water-based-mud‚ WBM (Drilling fluid) using the OFITE mud balance. Theory: Drilling fluids are used during the drilling of boreholes‚ either for oil wells or water boles holes. One of the major functions of a drilling fluid includes providing hydrostatic pressure to prevent formation fluids from entering the wellbore. To ensure

Significant figures are essential to interpreting data because they allow for increased precision and accuracy. Also‚ using Excel‚ the density calculations could be performed quickly and accurately. In this experiment‚ the density of water was found by collecting the masses known‚ which was volumes of water. To determine what the unknown density is‚ the mass should be divided
