Although several studies have shown positive outcomes in response to spinal flexibility training programs, little is known about the management of sets and repetitions in traini…

Two different posterior-stabilized mobile-bearing TKA designs: navigator evaluation of intraoperative kinematic differences

2020

Purpose: The purpose of this study was to compare two types of posterior-stabilized (PS) mobile-bearing (MB) total knee arthroplasties (TKAs). The hypothesis was that no major differences were going to be found among the two TKA designs. Methods: Two cohorts of patients who were divided according to implant design (Cohort A, new design gradually reducing radius PS MB TKA; Cohort B, traditional dual-radius PS MB TKA) were analyzed by means of intraoperative navigation. All operations were guided by a non-image-based navigation system that recorded relative femoral and tibial positions in native and implanted knees during the following kinematic tests: passive range of motion (PROM), varus–va…

Treatment of Combined Medial and Lateral Collateral Ligament Insufficiency

2016

The medial and lateral collateral ligament complexes represent primary elbow ligament stabilizers. Injury to these structures may occur because of an elbow dislocation or due to a severe varus or valgus force. Most elbow dislocations are stable once reduced and may be treated conservatively. However, if the elbow remains unstable surgical treatment is recommended. Repair should be anatomical and should restore stability to the elbow in order to permit an early active range of motion. Reconstruction may be required in severe cases and where primary repair is not possible. Depending on the degree of instability, either one or both of the collateral ligament complexes may need to be repaired o…

Spätsynovektomie des Ellenbogens und Resektion des Radiusköpfchens bei chronischer Polyarthritis

2008

Between 1974 and 1984 16 patients with rheumatoid arthritis, who had elbow synovectomy and excision of the radial head, were revised with an average follow-up of 5 years after operation. Resection of the radial head was performed on 16 elbows, in 3 elbows the ulnar nerve was transposed. The indication for the operation were pain, swelling, warmth and radiological destruction. The parameters used, to assess efficacy of the operation were range of motion, local finding and patient satisfaction. Synovectomy results were good especially in respect of relief of pain and range of motion. The good results justify elbow synovectomy even in the late stages of disease.

Tetragonal tungsten bronzes Nb8−xW9+xO47−δ: optimization strategies and transport properties of a new n-type thermoelectric oxide

2015

Engineering of nanoscaled structures may help controlling the electrical and thermal transport in solids, in particular for thermoelectric applications that require the combination of low thermal conductivity and low electrical resistivity. The tetragonal tungsten bronzes Nb8−xW9+xO47 (TTB) allow a continuous variation of the charge carrier concentration while fulfilling at the same time the concept of a “phonon-glass electron-crystal” through a layered nanostructure defined by intrinsic crystallographic shear planes. The thermoelectric properties of the tetragonal tungsten bronzes Nb8−xW9+xO47−δ (0 < x < 2) were studied in the temperature range from 373 to 973 K. Structural defects and the…

Search for a diffuse flux of high-energy ¿µ with the ANTARES neutrino telescope

2011

A search for a diffuse flux of astrophysical muon neutrinos, using data collected by the ANTARES neutrino telescope is presented. A $(0.83\times 2\pi)$ sr sky was monitored for a total of 334 days of equivalent live time. The searched signal corresponds to an excess of events, produced by astrophysical sources, over the expected atmospheric neutrino background. The observed number of events is found compatible with the background expectation. Assuming an $E^{-2}$ flux spectrum, a 90% c.l. upper limit on the diffuse $\nu_\mu$ flux of $E^2\Phi_{90%} = 5.3 \times 10^{-8} \ \mathrm{GeV\ cm^{-2}\ s^{-1}\ sr^{-1}} $ in the energy range 20 TeV - 2.5 PeV is obtained. Other signal models with differ…

Rearrangement of N-(3-pyridyl)nitramine

2009

AbstractContrary to other N-(pyridyl)nitramines, the title compound cannot be rearranged to 3-amino-2-nitropyridine or other isomers. Hypothetical products of its transformation under influence of concentrated sulphuric acid, viz. 3-hydroxypyridine, 3,3′-azoxypyridine and 3,3′-azopyridine, were obtained from 3-nitro- and 3-aminopyridine in oxidation and reduction reactions. N-(3-Pyridyl)nitramine was prepared and rearranged in concentrated sulphuric acid. 3-Hydroxypyridine and 3,3′-azoxypyridine were isolated from the reaction mixture, other products were identified by the HPLC and GCMS methods. The results indicate that N-(3-pyridyl)hydroxylamine is an intermediate formed from N-(3-pyridyl…

Synthesis and Rearrangement of 2-(N-Methyl-N-nitroamino)-4-phenylthiazole

2007

2-(N-Methyl-N-nitroamino)-4-phenylthiazole (5) was prepared and rearranged in aqueous dioxane under influence of sulphuric acid of various concentrations. 2-(N-Methylamino)- 5-nitro-4-phenylthiazole (6) was the only product up to 50% acid concentration. At higher acidities, significant amounts of nitro derivatives 3b and3c, substituted in benzene ring, were also formed. The result indicates that migration of the N-nitro group occurs on the intramolecular path, however, in concentrated sulphuric acid, formation of nitronium ion and ring nitration also takes place.

Acidity and basicity of primaryN-phenylnitramines: catalytic effect of protons on the nitramine rearrangement

2002

Para-substituted N-phenylnitramines were prepared either by oxidation of diazonium salts or by nitration under alkaline or acidic conditions. Isotopic [15N-NO2] labelling indicated that the bands characteristic of the N-nitro group appear in the 1318–1323 and 1585–1607 cm−1 regions. In the nitrogen NMR spectra, the nitramino group gives two resonances at −193 ± 3 (NH) and −32 ± 3 ppm (NO2). The chemical shifts in proton and carbon NMR spectra are predictable, based on increments and the additivity rule. The spectral data indicate the lack of conjugation between the nitramino group and another substituent bound to the ring. It seems to contradict the well-known fact that substituents strongl…
