Investigation Followup PROCEDURE The purpose of this experiment is to test different minerals to see where on the Mohs hardness scale they would fit. My question and problem‚ “What mineral is the hardest out of all?” My hypothesis is by looking at all mine minerals‚ amethyst is the hardest mineral‚ followed by opal‚ than apatite‚ then halite‚ than graphite and the muscovite will be the softest mineral. To begin this experiment‚ I purchased and gathered all my materials

Phuong Pham Prof. Johnson Lab 3 Gravimetric determination of Calcium as CaC2O4.H2O Feb‚ 27‚ 2014 I. Objective: The purpose of this lab is to determine how well gravimetric method measures the calcium level in a solution of known calcium concentration. II. Method: a) Overview: In this lab we will prepare 25 mL known concentration Calcium solutions. Then we will use Gravimetric method to determine the concentration of Calcium in each solution to figure out how well this method is. As we know

Osteoporosis is a disease characterized by low bone density‚ which can lead to an increased risk of bone fractures1. Osteoporosis is closely linked to bone remodeling2‚ an adaptive process which maintains bone tissue integrity throughout one’s lifetime3. This process is carried out by specialized groups of bone cells known as basic multicellular units (BMUs) which dictate the processes of coupled bone breakdown and bone formation.3 During osteoporosis‚ this bone turnover rate accelerates and bone

In biomedical applications‚ bioceramics are commonly used to modify the surface of the metals in exploitation as orthopaedic implants for humans. The diseases such as osteoporosis‚ osteoarthritis‚ bone tumour and trauma are the reasons for joint replacements in population over 50 years of age in developed countries. The Total Hip Replacement (THR) is an excellent alternative for patients suffering from joint failure caused by osteoarthritis. The historical failure of artificial implant restorative

Clayton’s survival I woke up hazed with blurred vision. The right side of my face was dried and burned. The left side of my face was soaked in salt water and blood. I was freaked out and picked up my head and blinked rapidly. I saw nothing but blue for miles and miles‚ the sky and the water. When I looked down I saw nothing but a small black and orange rubber dingy. I tried to think about what had happened. It was then when I realized I couldn’t even remember my own name. Then panic just settled

Facet Syndrome Facet syndrome is a condition in which joints (facet joints) that connect the bones of the spine (vertebrae) become damaged. Facet joints help the spine move‚ and they usually wear down (degenerate) or become inflamed as you age. This can cause pain and stiffness in the neck (cervical facet syndrome) or in the lower back (lumbar facet syndrome). When a facet joint becomes damaged‚ a vertebra may slip forward‚ out of its normal place in the spine. Damage to a facet joint can also

COMBINATION ARCH BAR AND QUICK FIX AS MAXILLOMANDIBULAR FIXATION IN THE ANGLE AND SYMPHISIS FRACTURE OF MANDIBLE (CASE REPORT) Introduction Mandible is a corticocancelous bone and constitutes the strongest and most rigid component of the facial skeleton‚ second most commonly fractured bones of the face and this is directly related to its prominent and exposed position. Prevalence rates epidemiological studies for fracture mandible are between 60 and 81%1. The etiology of symphysis and parasymphysis

Osteogenesis Imperfecta (OI) is known as brittle bone disease‚ and is a genetic disorder in which an individual has weakened bones that may fracture in situations of minor to inexplicable trauma. OI spans from a slight degree to the more critical cases which may lead to death moments after their delivery or prior to their existence (“Learning About Osteogenesis Imperfecta‚” 2012). No two people suffering from this condition share the same measure of difficulty. In fact‚ though there are various forms

Bone tissue continuously renews itself throughout life as a result of a variety of stimuli by the process of bone remodeling‚ in which old bone is replaced by new bone in order to preserve bone strength and mineral stability. It requires a particular balance between bone deposition and resorption‚ by the combined action of osteoblasts and osteoclasts‚ respectively. This process prevents the accumulation of bone micro-damage‚ removing injured bone and reshaping bones in response to use and disuse

Perthes Disease Perthes Disease‚ also known as Legg-Calve Perthes Disease is a childhood disorder that affects the head of the femur bone‚ where it connects to the hip bone. Begins in childhood and affects boys more than girls between the ages 4-8 and is more common in Caucasian children than those of an ethnic back round. Usually it only affects one hip‚ but in 10% of some cases it affects both. This is not an infectious disease‚ so other children in the house won’t be affected. It occurs when
