The submitted paper deals with the problems of trapping and enriching the gases and aerosols of the substances to be determined in the ambient atmosphere. Further, the paper is focused on the working principle of the miniaturized portable continuous concentrator we have designed and the possibilities of its application in air sampling and accumulation of organic and inorganic substances with wh...

Communications to the Editor infusion of fluid, in our experience, even 5 to 10 mg/kg cannot always be administered due to the development ofhypotension and cardiovascular depression during the infusion. This could be explained by the fact that the typical neurosurgical patient requiring pentobarbital coma is significantly dehydrated by fluid restriction, mannitol administration, and diuretic t...

22 The purpose of this work is to explore the use of image registration-derived variables associated 23 with computed tomographic (CT) imaging of the lung acquired at multiple volumes. As an 24 evaluation of the utility of such an imaging approach, we explore two groups at the extremes of 25 population ranging from normals to severe asthmatics. A mass preserving image registration 26 technique ...

We present a detailed study of the mode structure of inverse opal photonic crystal materials with an emphasis on their potential use in optical trapping and cooling. In particular, we analyze the modes corresponding to the upper and lower band edges of a high refractive index inverse opal, i.e., the so-called ;;air' and ;;dielectric' bands. In the dielectric band, we demonstrate optical intensi...

ventilation defects during the breath-hold (a, white arrows) in a volunteer with asthma. During the forced exhalation, residual signal due to gas trapping is evident in MRI (b, arrows) and air trapping is confirmed in MDCT during breath-hold at FRC (d, arrows). Figure 1. Subset of MIP time-frame images during dynamic ventilation showing intense signal enhancement during inspiration (arrow, 6 s)...
