OBJECTIVE Facial symmetry is an important factor affecting esthetics. Thus, its restoration is an essential task in maxillofacial surgery. The aim of this study is to develop an objective measure of facial asymmetry by a novel approach where both the shape and the color are taken into account and to validate its correlation with perception. METHODS Optical three-dimensional (3D) face scans of...

politics as an arena of macro decisions that influence on life of all human, from the start, connected to current thought in societies, but because that such conjunction done more according to necessity, events and or selectivity, therefore led to specific results for each two. in modern age, for the sake of birth of new age and its reciprocity with subjective and objective structures in past, ...

introduction: one of the most common syndromes in parkinson's disease (pd) is rigidity. currently, an index is used to evaluate the level of pd by the clinical measurement of rigidity in the upper extremity. the index uses a subjective method called unified parkinson's disease rating system (updrs). the subjective nature of this method makes the influence of physician in the measureme...

The relationship among changes in thirst sensations, blood variables, and differential fluid intake in hypohydrated humans was examined. Seven subjects were hypohydrated by 0%, 3%, 5%, and 7% of their body weight on four separate trials which were systematically randomized between subjects. Hypohydration levels were achieved with a regimen of restricted food and fluid intake and moderate heat-e...

BACKGROUND There is accumulating evidence supporting the association between neighborhood built environments and adults' physical activity (PA) and sedentary time (ST); however, few studies have investigated these associations in adolescents. A better understanding of the features of the built environment that encourage PA or ST is therefore of critical importance to promote health and wellbein...

Humans have the ability to mentally travel forward and back in time. They can retrieve vivid memories of past events (episodic memories) and can imagine the future (planning). Although it has been suggested that this is a uniquely human ability, the evidence for subjective time travel in humans is typically based on verbal report and elaboration. Such evidence cannot be obtained from animals. H...

Humans evolved in populations structured in groups that extended beyond the nuclear family. Individuals interacted with each other within these groups and there was limited migration and sometimes conflicts between these groups. Suppose that during this evolution, individuals transmitted their behaviors or preferences to their (genetic or cultural) offspring, and that material outcomes resultin...

During man’s relatively brief existence on this planet, he has relied on the bounty of its flora and fauna for his existence. He has harvested wildlife for food, clothing, shelter, medicines, beasts of burden, pets, and companionship. Over most of this period, this harvesting and exploitation had little impact on those resources. Human population was very low, and most animal and plant populati...
