The aim of this study was to validate a wearable inertial measurement unit (IMU), containing a 3D accelerometer and gyroscope, for the estimation of countermovement jump height. The absolute vertical acceleration of the IMU positioned on the back of the participant at L5 level, compensated for trunk rotations, was used to obtain jump height by applying the equation of free-fall to the motion of...

Results Patients, 22 (43.1%) were male and 29 (56.9%) were female with age of disease onset 5 (1-10) years, age of diagnosis and onset of therapy were 6.4 (1.3 to 11) years. According to Tel Hashomer criteria, severity score of the disease was 7 (4-10). When compered of height and weight of the patients at the beginning and at the one year of colchicine treatment a significant increase was foun...

The method of Walker and Wood is used to completely determine the nilpotence height of the elements P s t in the Steenrod algebra at the prime 2. In particular, it is shown that (P s t ) 2bs/tc+2 = 0 for all s ≥ 0, t ≥ 1. In addition, several interesting relations in A are developed in order to carry out the proof.

We present worst-case lower bounds on the minimum size of a binary space partition (BSP) tree as a function of its height, for a set S of n axis-parallel line segments in the plane. We assume that the BSP uses only axis-parallel cutting lines. These lower bounds imply that, in the worst case, a BSP tree of height O(log n) must have size Ω(n logn) and a BSP tree of size O(n) must have height Ω(n...

maternal nutritional is the most important environmental factor influencing pregnancy outcome. while studies showed association between maternal iron-micronutrient deficiencies with pregnancy outcome, data examining impact of micronutrient supplementation on growth rate beyond birth are sparse. present study examined the relationship between iron and multivitamins supplementation on growth rate...

This study aimed to evaluate the efficiency of organic compost produced through composting in development Moringa oleifera seedlings. The experiment was carried out a greenhouse Feira de Santana- BA, Brazil. design randomized blocks (RBD), with seven treatments per block and four replicates. following were tested: commercial substrate; sand (S); S/organic (OC) 80/20; S/OC 60/40; 40/60; 20/80; 0...

Characteristics and behavior of the flow in hydraulic structures, a complex phenomenon that isimperative to use software that will beto be study.Gabiony stepped spillway is a simple hydraulicstructures to control erosion downstream of dams, and, depreciation of structures is used. Roughstairway consisting of overflow from the stairs near the crest of the weir is started and continues tohave a l...

We prove that every height-2 finite poset with three or more points has an incomparable pair (.x, J) such that the proportion of all linear extensions of the poset in which s is less than y is between l/3 and 213. A related result of Koml6s says that the containment interval [l/3,2/3] shrinks to [l/2, l/2] in the limit as the width of height-2 posets becomes large. We conjecture that a poset de...
