Existence result of an effective stress for an isotropic visco-plastic composite
We define and present some theoretical characterizations of associated constitutive equations for a visco-plastic deformation of a composite. Introducing of an adequate topological framework for some visco-plastic state parameters, when considered a nonlinear stress-strain relations of Prandtl-Reuss type, we obtain the existence and uniqueness results of a steady state for a composite reinforced with other inclusions. The time-dependent plastic strains

Aim and objectives: To explore the views and knowledge on oral health care by caregivers working in the Bucharest residential centre, Recuperation and rehabilitee centre for persons with handicap, using a questionnaire. Design: The questionnaire was translated from Swedish into Romanian and consisted of 30 questions; 18 were closed questions with three to four alternatives, 12 were constructed as a Visual Analogue Scale (VAS). The questionnaire was

Aim: To carry out a field study of the oral health status, and evaluate the treatment needs of subjects with multiple disabilities in a long term residential care setting “Recuperation and rehabilitee centre for persons with handicap” (CRRPH) in Bucharest, Romania. Design: All residents were included in the study. Clinical examinations were based on the World Health Organisation criteria for field studies and carried out in the dental clinic

Questions: Litter quantity in grasslands is highly affected by disturbance regime and influences seed recruitment of constituent species through differentmechanisms. Does litter act as a mechanical barrier to burial of freshly shed seeds, and does seed morphology affect this? How is the fate and mobility of seeds affected by litter compared to that of seeds in the seed bank? Location: Transylvanian Lowland, Romania. Methods: We analysed the seed

Castor oil is one of the oldest drugs. When given orally, it has a laxative effect and induces labor in pregnant females. The effects of castor oil are mediated by ricinoleic acid, a hydroxylated fatty acid released from castor oil by intestinal lipases. Despite the wide-spread use of castor oil in conventional and folk medicine, the molecular mechanism by which ricinoleic acid acts remains unknown. Here we show that the EP3 prostanoid receptor is
