Traveling on arboreal substrates is common among most small mammals living anywhere vegetation grows. Because arboreal supports vary considerably in surface texture, animals must be able to adjust their locomotor biomechanics to remain stable on such supports. I examined how gray short-tailed opossums (Monodelphis domestica), which are generalized marsupials living on or near the ground, adjust...

A multi-modal mouse incorporating tactile and force feedback was tested in a target selection task with 12 subjects . Four feedback conditions (normal , tactile , force , tactile 1 force) were combined with three target distances and three target sizes . We found significant reductions in the overall movement times and in the time to stop the cursor after entering the target . This ef fect was ...

Background & Aims: The purpose of the present study was to evaluate the effect of 8 weeks specific aquatic therapy on kyphosis angle and some pulmonary indices in male university students with kyphosis. Methods: A total of 15 males with increased normal thoracic Kyphosis (kyphosis 40 degrees, 20.70 ± 0.705 years old, height 175.5 ± 6.19 cm, weight 64.19 ± 8.23 kg) were selected. Before and afte...

objective: intrusion as a type of tooth movement is managed by different mechanotherapies during various treatment stages. the morphology of the apical third of the teeth to be intruded plays an important role in the risk of root resorption due to the raise of stresses. the main goal of this study was to compare various types of apical third of the teeth while loaded by an intrusive force. mate...

This study investigated the effects of modifying contact finger forces in one direction-normal or tangential-on the entire set of the contact forces, while statically holding an object. Subjects grasped a handle instrumented with finger force-moment sensors, maintained it at rest in the air, and then slowly: (1) increased the grasping force, (2) tried to spread fingers apart, and (3) tried to s...

measurement of the loads exerted on the limb is a fundamental part of designing of an assistive device, which has been done by using strain gauges or a transducer. although calculation of loads applied on an orthosis coefficients achieved from calibration is a standard way, most of researchers determined the loads based on available equations. therefore, the aim of this research is finding the ...

Previous studies have shown that the interactions of human hand digits are influenced by internal constraints, i.e., biomechanical and central constraints. However, little is currently known about the influence of externally imposed mechanical constraints on multi-finger behavior. This study investigates maximal digit force production during fixed object and free object prehension in statics. T...

Measurements of the frequency-force relationship were made in left atrial muscle from euthyroid and hyperthyroid guinea pigs and the effects of calcium and norepinephrine on this relationship examined. Isometric contractile force was measured with the muscle suspended in a bath of Krebs-Henseleit solution oxygenated by a gas mixture of 95£ O2-5% CO2 at 28°C. Frequency of stimulation was varied ...

Abstract In this paper the generalized model of contact two plan bodies that roll and slide or just is presented. The analytical solution correct distribution pressure in realized presence normal compressive force, which realizes contact, as well force pair a tangential force. This can be used on sprocket teeth due to sliding rolling itself gear pole. results obtained have been experimentally c...
