The recent development of high resolution spectrographs for exoplanetary research in the visible range makes suitable an improvement of our knowledge of the high resolution spectrum of methane. In this contribution, the weak and highly congested absorption spectrum of methane in the 10 800-14 000 cm region (0.71-0.

The integration of an industry ready packaged Sb-based Vertical-External-Cavity Surface-Emitting-Laser (VECSEL) into a Cavity Ring Down Spectrometer (CRDS) is presented. The instrument operates in the important 2.3 μm atmospheric transparency window and provides a high sensitivity (minimum detectable absorption of 9 × 10(-11) cm(-1)) over a wide spectra range.

The room temperature self- and foreign-continua of water vapor have been measured near 4250 cm(-1) with a newly developed high sensitivity cavity ring down spectrometer (CRDS). The typical sensitivity of the recordings is αmin≈ 6 × 10(-10) cm(-1) which is two orders of magnitude better than previous Fourier transform spectroscopy (FTS) measurements in the spectral region. The investigated spectral interval is located in the low energy range of the important 2.

The purpose of the study--to develop a diagnostic and management tactics for patients with biliary sludge (BS) in an outpatient setting. The study included 115 patients who, according to the ultrasound revealed a BS. Own methodological approach used by ultrasound scan of the gall bladder and the interpretation of ultrasonographic BS types: Type 1 (suspension echo-positive particles) was set at 59.

This paper deals with the possibility of application of aluminum phthalocyanine (AlPc) nanoparticles in clinical practice. AlPc fluoresces in the molecular form but in the form of nanoparticles it does not. Separation of molecules from an AlPc nanoparticle and therefore the appearance of fluorescence occurs under the effect of a number of biochemo-physical factors.

A total of 25 children with bronchial asthma and 40 children with cutaneous and dermato-respiratory + manifestations of allergy and concomitant injury to the gastrointestinal tract were under observation at an allergological clinic. In addition to the general clinical and allergological examination, radionuclide studies were performed by means of scintipneumography with 99mTc and hepatobiliscintigraphy with 99mTc HIDA. The data obtained indicate that radionuclide methods can be used in childhood allergological practice in the capacity of screening diagnosis as well as in the capacity of adjuvant + methods of examination, making it possible to perform investigations necessary for diagnosis establishment in a more precise and atraumatic manner.

A questionnaire survey of the staff of curative and preventive institutions on the subject of management style, business and personal qualities of their leaders was conducted. The diversity of psychological features was detected in the microclimate of the collectives surveyed naturally conditioned by the interaction between the leader and the collective. The resulting psychological microclimate determines the different degree of willingness to welcome a new economic mechanism: from the possibility of complete realization of its principles by the entire collective to the complete declination.

The sensitivity and specificity of ultrasound investigation (USI) and x-ray methods of indirect and direct contrast studies of the biliary system in the diagnosis of cholecysto- and choledocholithiasis were compared by a blind control method. USI was shown to be superior over all x-ray contrast methods in the diagnosis of cholecystolithiasis. The diagnosis of choledocholithiasis usually requires the use of x-ray methods among which preference should be given to endoscopic retrograde cholangiography as the most informative method permitting simultaneous intervention on the major duodenal papilla.

Optimum multimodality examination of the pancreas includes sonographic, radioimmunological, scintigraphic and angiographic studies. Sonography is a method of choice to study anatomotopographic features of the pancreas. The radioimmunoassay is intended both for the mass screening of patients with hepatogastro-duodenal diseases and for the differential diagnosis of chronic pancreatitis by the nature and type of disease.
