Background: Assessment of aerobic capacity is of vital importance in both general community and occupational settings. Valid, reliable and feasible tests are required to indicate the functionality of cardiopulmonary system. The present study was carried out aiming to evaluate the suitability of the Chester step test (CST) as a field test to measure the Iranians’ aerobic capacity.    Materials ...

Companhia Siderúrgica de Tubarão CST, is investing to expand production level in 50%, adding new equipment and altering production process. Simulation is widely used in CST, mainly in strategic phases prior to capital investment. A previous simulation model developed with ARENA was enhanced to help CST achieve new goals: to analyze new process plan with operational details, testing different pr...

Let $$T=\{\triangle _1,\ldots ,\triangle _n\}$$ be a set of n triangles in $$\mathbb {R}^3$$ with pairwise-disjoint interiors, and let B convex polytope constant number faces. For each i, $$C_i = \triangle _i \oplus r_i B$$ denote the Minkowski sum $$\triangle _i$$ copy scaled by $$r_i>0$$ . We show that if scaling factors $$r_1, \ldots , r_n$$ are chosen randomly then expected complexity union...

PURPOSE To compare intraocular pressure (IOP) between the new non-contact tonometer Corvis ST (CST), the Goldmann applanation tonometry (GAT) and Icare Pro rebound tonometer (PRO). METHODS A total of 178 eyes of 178 healthy subjects were selected for the study. Measurements of IOP were made in a random order with GAT, PRO and CST. Central corneal thickness (CCT) was determined by ultrasound p...

As most spinal cord injuries (SCIs) are incomplete, an important target for promoting neural repair and recovery of lost motor function is to promote the connections of spared descending spinal pathways with spinal motor circuits. Among the pathways, the corticospinal tract (CST) is most associated with skilled voluntary functions in humans and many animals. CST loss, whether at its origin in t...

For aerodynamic modeling and optimization, it is desirable to limit the number of design variables to reduce model complexity and the requirements of the applied optimization scheme. The Class/Shape Transformation (CST) surface parameterization method presented by Kulfan has proven to be particularly useful for this while maintaining a wide range of applications. These include everything from s...

UNLABELLED Chronic spinal cord injury (SCI) is a formidable hurdle that prevents a large number of injured axons from crossing the lesion, particularly the corticospinal tract (CST). This study shows that Pten deletion in the adult mouse cortex enhances compensatory sprouting of uninjured CST axons. Furthermore, forced upregulation of mammalian target of rapamycin (mTOR) initiated either 1 mont...
