The aim of this study was to investigate the effect of two different tapering period lengths on the concentration of plasma interleukin- 6 (IL-6), interleukin (IL-1β) and tumor necrosis factor-α (TNF-α) and performance in elite male cyclists. To this end, after completing 8 weeks progressive endurance exercise, twenty four high-level endurance cyclists were randomly assigned to one of two group...

Introduction: Modular head-neck total hip arthroplasty (THA) offers several benefits for orthopaedic surgeons, including intraoperative flexibility and the ability to change the head at revision surgery [1]. However, modularity at the head-neck taper, especially the use of metallic heads and stems, can lead to fretting and corrosion at the taper junction, leading to metal ions and debris releas...

Taper models, which describe the shape of tree stems, are central to estimating stem volume. Literature provides both taper- and volume models for three main species in Norway, Norway spruce, Scots pine, birch. These however, were mainly developed using approaches established over 50 years ago, without consistency between taper We tested eleven equations six bark thickness. The fitted evaluated...

introduction: the objective of this study was to compare the shaping ability of three rotary filing systems; constant taper k3 instruments, constant taper profile instruments and progressive taper protaper rotary instruments in clear resin blocks with simulated curved root canals. materials and methods: forty five resin blocks were divided into three groups. group a preparation was conducted wi...

We demonstrate an all-fiber add-drop filter composed of a microfiber knot (working as a resonator) and a fiber taper (working as a dropping fiber). The dropping taper can be either parallel or perpendicular to the input port of the filter. A quality factor (Q factor) of 13,000 is obtained from a parallel-coupling 308 microm diameter microknot add-drop filter with a free spectral range (FSR) of ...

the aim of the present study was to monitor the pre-season preparatory training effectiveness by both the mood profile and physical performance. 15 male soccer players mean age 25±2.21 yr, height 180.27±2.58 cm, weight 81.13±5.49 kg and 5 years playing experience voluntary participated in this study. the program combined strength and endurance training, 4 weeks progressive training and the 5th ...

To a good approximation, the electromagnetic-propagation characteristics of graded-index waveguides can be written in terms of polynomial-Gaussian modes. For uniform quadratic-index waveguides the behavior of these modes is well known. However, there are sometimes practical reasons for using tapered waveguides, but detailed propagation solutions are known for only a few specific taper functions...

The ability to achieve near lossless coupling between a waveguide and a resonator is fundamental to many quantum-optical studies as well as to practical applications of such structures. The nature of loss at the junction is described by a figure of merit called ideality. It is shown here that under appropriate conditions ideality in excess of 99.97% is possible using fiber-taper coupling to hig...

Measurements of the roll-damping derivative (lp) of three wing planforms were made by the free-flight roll-balance technique over the Mach number range 0-7 to 1.4. The wings were all of RAE 102 section, 7" 5 per cent t/c and aspect ratio 2.83 but varied in sweep and taper ratio. The two wings of taper ratio 0.33 showed little loss of damping in the transonic region but the 50 deg delta wing suf...

confirmed by histologic analysis, around a dual taper modular hip arthroplasty. The coronal MAVRIC MR image demonstrates a synovial thickness of 22mm (white arrowheads). Decompression of ALTR into the iliopsoas bursa is indicated with a white arrow. This subject was given an ALVAL score of 10. 6266 Magnetic Resonance Imaging Findings in a Dual Taper, Modular Total Hip Arthroplasty Matthew F. Ko...
