Bicycle saddle height configuration may affect pedal force application. Our aim was to compare pedal force effectiveness for different saddle height configurations. Eleven cyclists (38 ±12 years) and eleven triathletes (44 ±8 years) with competitive experience performed 2-min trials at four different saddle heights (preferred, high, low, theoretical optimal) each separated by one minute of rest...

peptic ulcer is a very common disorder in horse race and foals. in the present research possible relationship between gastric ulcer and the prevalence of cardiac arrhythmia were studied in two different horse race. in this respect, 13 caspian miniature horses and 8 arab horses were studied. gastric ulcers and cardiac arrhythmias were diagnosed in 13 horses (62%) and 12 (57%) out of 211 horses, ...

seven caspian miniature horses, aged above two years, were used for this study. the skeleton of these horses were cleaned and prepared using appropriate techniques. the vertebral column was studied and photographed. the vertebral column in one of these horses showed variations in thoracic, lumbar and sacral region. the vertebral formola was c7, t19,l5,s6 and a pair of 19th rib was fused with th...

One of the most attractive recent approaches to processing well-structured large-scale convex optimization problems is based on smooth convex-concave saddle point reformulation of the problem of interest and solving the resulting problem by a fast First Order saddle point method utilizing smoothness of the saddle point cost function. In this paper, we demonstrate that when the saddle point cost...

This paper considers continuously differentiable functions of two vector variables that have (possibly a continuum of) min-max saddle points. We study the asymptotic convergence properties of the associated saddle-point dynamics (gradient-descent in the first variable and gradientascent in the second one). We identify a suite of complementary conditions under which the set of saddle points is a...

To investigate the prevalence of Cryptosporidium infection in horses, a total of 221 faecal specimenswere collected from 18 villages of Urmia, northwestern Iran. The samples were studied microscopically bymodified Ziehl-Neelsen staining. The cryptosporidial infection was found in the collected samples from 11 of18 villages. Although the prevalence of the infection was 15.8%, none of the infecte...
