BACKGROUND Spontaneous ventilation, mechanical controlled ventilation, apneic intermittent ventilation, and jet ventilation are commonly used during interventional suspension microlaryngoscopy. The aim of this study was to investigate specific complications of each technique, with special emphasis on transtracheal and transglottal jet ventilation. METHODS The authors performed a retrospective...

We present new images of the two-sided VLBIstructure of the radio galaxy CygnusA at 1.6GHz, 22GHz and 43GHz. The maps show the jet and counter-jet of CygnusA on scales from ∼ 400 to 0.1 milliarcseconds, corresponding to projected sizes of ∼ 300 pc to 0.07 pc. Our best 22GHz image shows a small (few degree) misalignment of the VLBI-jets with the kpc-jets, longitudinal oscillations of the jet’s r...

In the repetitive approach to the theory of jet bundles there are three methods of repetition, which yield non-holonomic, semi-holonomic, and holonomic jet bundles respectively. However the classical approach to holonomic jet bundles failed to be truly repetitive, for it must resort to such a non-repetitive coordinatedependent construction as Taylor expansion. The principal objective in this pa...

Excel lacks features for modular design. Had it such features, as do most programming languages, they would save time, avoid unneeded programming, make mistakes less likely, make code-control easier, help organisations adopt a uniform house style, and open business opportunities in buying and selling spreadsheet modules. I present Excelsior, a system for bringing these benefits to Excel.

Athletes often are required to travel for sports participation, both for practice and competition. A number of those crossing multiple time zones will develop jet lag disorder with possible negative consequences on their performance. This review will discuss the etiology of jet lag disorder and the techniques that are available to shorten or minimize its effects. This includes both pharmacologi...

Accumulation of large, high-quality satellite and in situ data led to significant improvements in the description of the mean dynamic ocean topography (MDOT) [6]. The new models of MDOT, with the resolution improved to 50-100 km, have not only revealed important details in the complex mesoscale structure of circulation systems such as the Gulf Stream, Kuroshio Extension, and Antarctic Circumpol...

Wood density variations in 110-year-old European ash (Fraxinus excelsior L.) wood was examined in relation with different water regime treatments in two floodplain forest sites of similar elevation (Lednice 161 m a.s.l. and Tvrdonice 154 m a.s.l.) in South Moravia Czech Republic, in order to infer on the oven-dry wood variability. Sample logs were obtained from breast height 1.3 m of the ground...

Last decades, the number of routine childhood vaccinations has increased considerably, which consequently has led to multiple vaccine injections per consultation. Implementation of additional vaccines will probably lead to more than 2 vaccine injections per consult, which might be a barrier for parents to vaccinate their child. A decrease in vaccination coverage, however, increases the risk of ...

A new method of multiplexing the speckle patterns needed in multicomponent digital shearography systems is presented. Frequency-division multiplexing (FDM) of the measurement channels is achieved by recording speckle patterns from objects illuminated by intensity-modulated sources. Each source is modulated at a discrete frequency, which is less than half of the camera frame rate, and a bank of ...

We present two measurements related to jet production in p+p and central Au+Au collisions at √ sNN=200 GeV. Firstly, a study of semi-inclusive charged recoil jets coincident with high-pT direct-photon and neutral pions, and secondly, the hadron correlations with respect to reconstructed di-jet triggers. Indication of medium effects is observed by comparing γ+jet and π0+jet measurements. The di-...
