Clinical and Histological Experimental Investigation of Temporomandibular Joint Traumatic Arthritis

Objective: To investigate the symptoms and pathology related to classification of temporomandibular joint traumatic arthritis (TMJTA) and the use of classification of various forms. Methods: The clinical and imaging data of 41 patients with TMJTA caused by joint blunt trauma, 32 patients with chronic TMJTA caused by condylar fractures and 6 patients with a long time opening limitation after con...

Clinical evaluation of oral lesions associated with dermatologic diseases.

BACKGROUND Dermatologic diseases are not only represented by lesions affecting the skin but also by manifestations that may involve the mucous membranes, including oral mucosa. OBJECTIVES To evaluate the frequency of oral manifestations associated with dermatologic diseases considering location and clinical characteristics of the lesions found and also gender, age and race of patients. METH...

Experimental Performance Investigation of Cooling or Heating Coil Valves and Their Impact on Temperature Controls

Hysteresis and nonlinearity exist in most valves that are utilized in building HVAC systems, such as in cooling or heating coil valves. The hysteresis mainly comes from the manufacturing clearance in an actuator gearbox and nonlinearity in the variation of the regulated flow with respect to control signal originates from valve design. The combination of valve hysteresis and nonlinearity poses s...

The Effects of Management Controls and National Culture on Manufacturing Performance: an Experimental Investigation*

The increasing dominance of Asian manufacturing firms in the global economy has raised an important issue: whether these firms’ superior manufacturing performance is caused by their management control systems, the national culture of their employees, or the interaction of these two factors. This experimental study provides a direct test of the effects of national culture and management control ...
