Measurement and calculation of CO (7-0) overtone line intensities

Intensities of 14 lines in the sixth overtone (7-0) band of carbon monoxide (12C16O) are measured in the visible range between 14 300 and 14 500 cm-1 using a frequency-stabilized cavity ring-down spectrometer. This is the first observation of such a high and weak overtone spectrum of the CO molecule. A theoretical model is constructed and tested based on the use of a high accuracy ab initio dipole moment curve and a semi-empirical potential energy curve. Accurate studies of high overtone transitions provide a challenge to both experiment and theory as the lines are very weak: below 2 × 10-29 cm molecule-1 at 296 K. Agreement between theory and experiment within the experimental uncertainty of a few percent is obtained. However, this agreement is only achieved after issues with the stability of the Davidson correction to the multi-reference configuration interaction calculations are addressed

Measurements of the Diffusion and Reflection Coefficients of Cd(1S0\text{}^{1}S_{0}) in Noble Gases

A new method of simultaneous determining of the diffusion coefficient and the reflection coefficient of atoms from the reservoir walls is presented. The diffusion coefficient of cadmium atoms in the ground state in buffer noble gas atoms such as Ne, Ar, Kr, and Xe and reflection coefficient of Cd atoms from the quartz cell wall in the temperature range 350-550 K were determined. Experimental values of diffusion coefficient are compared with theoretical ones calculated from available potentials

The influence of duration of rheumatoid arthritis on the temperature of inflammed joints

Reumatoidalne Zapalenie Stawów (RZS) jest przewlekłą, zapalną chorobą układową tkanki łącznej. Celem niniejszej pracy była ocena wpływu czasu trwania choroby, od momentu postawienia diagnozy RZS, na temperaturę stawów objętych procesem zapalnym. Za pomocą kamery termowizyjnej przebadano następujące stawy: stawy nadgarstka, stawy śródręczno-paliczkowe, stawy międzypaliczkowe bliższe, stawy międzypaliczkowe dalsze dłoni prawej i lewej oraz stawy: skokowo goleniowy i śródstopno-paliczkowy stopy prawej i lewej. Zaobserwowano istotnie niższą temperaturę stawu skokowo-goleniowego stopy prawej u pacjentów chorujących dłużej niż 10 lat w porównaniu z osobami zdrowymi.Rheumatoid Arthritis (RA) is a chronic inflammatory disease of human connective tissue. The aim of the study was to assess the impact of RA duration on the temperature of inflamed joints. Temperatures of the following joints were measured: wrist joints, metacarophalangeal joints, proximal interphalangeal joints, distal interphalangeal joints of left and right hand as well as ankle joints and metatarsophalangeal joints of right and left foot. Significantly lower right ankle joint temperature was observed for patients of more than 10 years’ disease duration compared to healthy subject

Collisional broadening and shift of Doppler-free two-photon thallium lines perturbed by rare-gas atoms

The extended Omont-Ueda-Kaulakys treatment of collisional effects on quasi-Rydberg states, in which the perturbation of the lower state is taken into account is applied to thallium-rare gas systems. The pressure broadening and shift coefficients of two-photon transitions in thallium involving the $6P_{1/2}{-}n P_{1/2,3/2}$ (n = 9-14) states are calculated and compared with experimental data obtained by Hermann et al. [Eur. Phys. J. D 1, 129 (1998)]
