Frequently in EPMA, the chemistry of an analyte (that is, the oxidation state and bonding of the elements in the material) is inferred from the composition, by stoichiometry or some other means. While this practice is usually adequate for determining the identity of pure single-phase materials, the results are often inconclusive when attempting similar analyses of complex mixtures composed of m...

Fluorescence microspectroscopy (FMS) with environmentally sensitive dyes provides information about local molecular surroundings at microscopic spatial resolution. Until recently, only probes exhibiting large spectral shifts due to local changes have been used. For filter-based experimental systems, where signal at different wavelengths is acquired sequentially, photostability has been required...

Cosmological theories for the origin and evolution of structure in the Universe are highly predictive of the form of the angular power spectrum of cosmic microwave background fluctuations. We present new results from a comprehensive study of CMB observations which provide the first measurements of the power spectrum all the way down to angular scales of ∼ 10 arcminutes. On large scales a joint ...

Modern computerized planning tools for periacetabular osteotomy (PAO) use either morphology-based or biomechanics-based methods. The latter relies on estimation of peak contact pressures and contact areas using either patient specific or constant thickness cartilage models. We performed a finite element analysis investigating the optimal reorientation of the acetabulum in PAO surgery based on s...

Unexpected tracheal narrowing was observed in a patient with Duchenne muscular dystrophy during a corrective operation for thoracolumbar scoliosis. As the operating time progressed, peak airway pressure and end-tidal CO2 increased gradually in the prone position. We found a floppy portion of the trachea using fiberoptic bronchoscopy (FB) in the prone position. We advanced a wire-reinforced tube...

OBJECTIVES The aim of this study was to determine whether exercises can change the cervical angle and respiratory function in smartphone users. METHODS Thirty healthy volunteers were recruited. The subjects were randomly divided into an exercise group and a control group. All participants used a smartphone for 1 hour while maintaining a sitting posture. Then, each group performed their assign...

The formation and underlying causes of pressure ulcers (PUs) are quite complex, with multiple influencing factors. However, by definition pressure ulcers cannot form without loading, or pressure, on tissue. Clinical interventions typically target the magnitude and/or duration of loading. Pressure magnitude is managed by the selection of support surfaces and postural supports as well as body pos...

BACKGROUND The aim of study was to evaluate the effect of mechanical ventilation mode type, pressure-controlled ventilation (PCV), or volume-controlled ventilation (VCV) on intra- and postoperative surgical bleeding in patients undergoing posterior lumbar interbody fusion (PLIF) surgery. METHODS This was a prospective, randomized, single-blinded, and parallel study that included 56 patients u...

the mediterranean is one of the most important cyclogenesis regions in the northern hemisphere. the depressions occurring in specific areas of the mediterranean region and cyclonic tracks have been the subject of extensive climatological research. the climate of the mediterranean region is conditioned by its position in the transition area between the sub-tropical high pressure belt and the mid...

OBJECTIVES Correct cuff inflation allows appropriate ventilation, and prevents aspiration pneumonia as well as several tracheal complications. The objective of this study was to evaluate endotracheal cuff pressure and/or tracheotomy tubes at zero, 30 and 60 degrees inclination of the patient's bed head section in adult intensive care units. METHODS A cross sectional study was carried out eval...
