depends less on the chemical composition of the paste and more on the physical structure. Fracture mechanics approach Fracture mechanics is the formation of cracks at the interface of the paste due to the presence of flaws (in aggregates) discontinuities and pores. There are sources of weaknesses and hence cracks influence the strength of the specimen. It is therefore important to understand the process of fracture of concrete under stress. Porosity :- relative volume of pores or voids in the paste

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 are very common; some complications can arise as a result of these fractures. Component 1: Identify the body systems affected by the disease Osteoporosis affects the skeletal system of the body. Osteoporosis is a condition caused

CT/CBCT imaging depends on both the initial radiographic valuation and the clinical findings. If the plain radiographs are negative‚ with no signs of fracture‚ no fluid levels‚ no mucosal thickening of the sinuses‚ and no orbital or soft tissue emphysema and there is no indication of penetrating injury‚ then the chance of finding a significant midface fracture on CT/CBCT evaluation. There are very high incidence of intracranial damage in such patients‚ and there are important questions relating to the

Osteoporosis is defined by the World Health Organization (WHO) as a bone mineral density of 2.5 standard deviations or more below the mean peak bone mass (average of young‚ healthy adults) as measured by dual-energy X-ray absorptiometry; the term "established osteoporosis" includes the presence of a fragility fracture.[2] The
