Abstract: Falling is the crucial concern in elder adults which can result into serious injury or rupture of bones especially hip bone injury or other joint fractures. Hence fall detection is necessary to minimize risk of injury. Accelerometer is the most widely used device to detect falls as it provides information about the sudden downward tilt. Tri-axial accelerometer provides measure of acceleration in three dimensions. Paper describes the review on fall detectors in which tri-axial accelerometer is used as the main component along with different sensors and systems.

Abstract: Cancers are the most serious problems of the medicine. Adequate treatment of early diagnosed patient gives the patient possibility of healing, to improve the quality of life and to return to normal life. Most of the tumors are characterized by the presence of one or several more or less specific markers. By processing the presence of multiple markers - although with a lower sensitivity and specificity - we get an overall picture of the body organs. The aim of this project is to monitor, evaluate and process results of magnetic resonance imaging. The results are provided to doctors in the form of graphs, 2D and 3D models and tables. This application also brings the possibility of processing error values of the measurements of markers.

Abstract: Musculoskeletal damage is a major health-related problem in working groups as well as in growing age population throughout the world. Due to the inefficiency of the current surgical treatment, Regenerative Medicine has recently grasped the attention of scientists. Tissue-engineering and cell-based therapies, two prominent branches of Regenerative Medicine, are considered as the most suitable techniques to repair the tissue damage. However, a huge number of autologous cells are required to address these practices. Since only small numbers of cells are obtainable from the patient, it requires expansion of cells in vitro. Nevertheless, these primary cells grow slowly in vitro and lose their general characteristics during prolonged culturing period. It has been shown through this thesis that several exogenous factors, which can be classified as physical, chemical, biological and culture-environmental, can modulate the culture parameters effectively. These can, therefore, support in promoting higher proliferation rate and also in maintaining the desired characteristics after the culturing period.

Abstract: Every day, we’re swimming in a sea of electromagnetic radiation produced by electrical appliances, power lines, wiring in buildings, and a group of other technologies that are part of modern life. Cell phones have become a vital part of our lives, and its use is not only restricted to voice conversations but also conveying news, high resolution pictures and internet. During recent years there has been increasing public concern on potential health risks from extremely low frequency electromagnetic fields and radiofrequency/microwave radiation emissions. It is fairly well established that at sufficiently high power levels, radiofrequency and microwave energy can produce deleterious biological effects. Some investigations suggested that these fields may have genotoxic effects and may increase the risk of several cancers and neurological disorders such as Alzheimer's disease. The aim of this review was to evaluate the influence of mobile telephone radiation on biological systems and health. It is concluded that these fields can influence several biological functions of cells and tissues, modulating intracellular reactive oxygen species levels and the cell cycle progression.

Abstract: Arsenic is most abundant element on the Earth and found in groundwater in both + (III) and + (V) oxidation states. If taken in sufficient quantities, arsenic can pose a threat to human health. In the rural area without awareness or high treatment cost it can consumed directly by local people. To reduce the effect on arsenic on drinking water medicated natural occurring plant seed is used for removal of toxic substance. In this study Moringa oleifera is used as coagulant material to reduce the toxicity of drinking water. Moringa oleifera is that seed which proved and optimized this problem in rural area. It can be reduced 91% of arsenic and 93% of hardness from drinking water.
