Housing preweaned dairy calves in pairs rather than individually has been found to positively affect behavioral responses in novel social and environmental situations, but concerns have been raised that close contact among very young animals may impair their health. In previous studies, the level of social contact permitted in individual housing has been auditory, visual, or physical contact. I...

Software simulations of the locomotion play an important role in the chassis design and dimensioning phase of planetary rovers. In this paper two key modeling techniques for simulating the physical contact between rover wheels and planetary surface will be presented. The first one is PCM (Polygonal Contact Model). Generally, PCM provides the contact dynamics between two bodies, which are specif...

Background and aim: Eczema is a common inflammatory skin disease. Although history and physical examination are important in diagnosis of allergen, because of extent of environmental allergens, those are not simply recognized. The objective of this study was to determine allergens in patients with contact or atopic dermatitis referred to Razi hospital.Materials and Meth...

BACKGROUND Extending contact with participants after the end of an initial intervention is associated with successful maintenance of weight loss and behavior change. However, cost-effective methods of extending intervention contact are needed. OBJECTIVE This study investigated whether extended contact via text message was efficacious in supporting long-term weight loss and physical activity a...

abstract: in the present paper, we give a necessary and sufficient condition for contact cr-warped product to be contact cr-product in kenmotsu space forms.
