Thermodynamics of gaseous strontium and calcium cerates studied by Knudsen effusion mass spectrometry and estimation of relative electron ionization cross-section for CeO(g).

Rationale: Ceria-based systems are of great interest because of their unique properties. Such systems may be used as anode materials for SOFCs or in oxygen sensors. The exploitation of these materials often requires high temperatures.

Linking pollution of roadside soils and ecotoxicological responses of five higher plants.

This research studies a typical landscape of an agricultural area separated from the road by a ditch with trees. Soils were sampled at 1, 2, 7, 25, and 50 m from the road. The concentrations of polycyclic aromatic hydrocarbons (PAH), total and phyto-available heavy metals (HM), total petroleum hydrocarbons (TPH), and de-icing salts (DS, Cl) were determined using standard techniques.

Crystal structures of two dimeric nickel di-phenyl-acetate com-plexes.

In the crystal structures of the title com-pounds, namely μ-aqua-κ :-di-μ-di-phenyl-acetato-κ :'-bis-[(di-phenyl-acetato-κ)bis-(pyridine-κ)nickel(II)], [Ni(CHO)(CHN)(HO)] () and μ-aqua-κ :-di-μ-di-phenyl-acetato-κ :'-bis-[(2,2'-bi-pyridine-κ ,')(di-phenyl-acetato-κ)nickel(II)]-aceto-nitrile-di-phenyl-acetic acid (1/2.5/1), [Ni(CHO)(CHN)(HO)]·2.5CHCN·CHO (), the com-plex units are stabilized by a variety of intra- and inter-molecular hydrogen bonds, as well as C-H⋯π and π-π contacts between the aromatic systems of the pyridine, dipyridyl and di-phenyl-acetate ligands.

[Easyhalers in practice for treating patients with asthma].

A comparative investigation was conducted to study the therapeutic effect of using two powder inhalers (the new-generation device--an easyhaler as well as an aerolyser inhaler) in daily practice for treating patients with moderate asthma. It showed the pharmacological equivalence, efficiency, and safety of applying a combination of the easyhalers budesonide and formoterol, as well as the simplicity and convenience to use the inhalers of this type.

[Biliary dysfunctions and their prevention].

Unlabelled: THE AIM OF REVIEW: To present the up-to-date methods of prophylaxis of biliary system pathology.

Original Position: The number of patients with biliary tract pathology is constantly growing up. Participation of psychovegetative state in the development of gallbladder dysfunction was confirmed.
