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...

Measurements of the Casimir force require the elimination of the electrostatic force between the surfaces. However, due to electrostatic patch potentials, the voltage required to minimize the total force may not be sufficient to completely nullify the electrostatic interaction. Thus, these surface potential variations cause an additional force, which can obscure the Casimir force signal. In thi...

The aim of this study was to assess handgrip and 5 other types of force in 52 women and to determine if handgrip force reflected general upper limb force capabilities correlated with age. The women were divided into subgroups according to age: 20-25, 45-50 and 55-65 years. Maximum forces of the right upper limb were measured in 6 types of force activities. In most tests the values of force show...

In addition to biting, it has been speculated that the forces resulting from pulling on food items may also contribute to feeding success in carnivorous vertebrates. We present an in vivo analysis of both bite and pulling forces in Varanus komodoensis, the Komodo dragon, to determine how they contribute to feeding behavior. Observations of cranial modeling and behavior suggest that V. komodoens...

We investigated the changes in the technical ability of force application/orientation against the ground vs. the physical capability of total force production after a multiple-set repeated sprints series. Twelve male physical education students familiar with sprint running performed four sets of five 6-s sprints (24s of passive rest between sprints, 3min between sets). Sprints were performed fr...

in this paper, the effect of air relative humidity and capillary force on contact geometry of surfaces based on jkr model by atomic force microscopy was investigated in order to manipulate nano-particles. with transition from macro to nano-scale, the effect of surface forces becomes more significant in comparison with inertial force. because contact mechanics models are based on surface energy ...

objective: : root resorption is a complication of orthodontic treatment and till date, there is a dearth of information regarding this subject. the aim of this study was to determine the relationship between orthodontic force and genetic expression of tgf-β(as an inflammatory cytokine) using the rt-pcr technique in rats. moreover, realization of the level of gene expression may help in the diff...

objectives: nowadays, snap-fits are used in the automotive industry as a proper alternative for mechanical joints, cabling joints, and car interior lining joints. due to the special form of these joints, which are assembled manually, the contact area between snap-fits and the worker's fingertips can be too small. this can cause skin pain on the worker's fingertips. therefore, an ergonomic study...
