(MUNKSGAARD INT PUBL LTD, 1994-12-15)The crystal structure of [CUCl2(C12H12N2)] is reported. The complex is monomeric, with the Cu atom coordinated to two N atoms and two Cl- ions. The compound displays simple paramagnetic behaviour.
-
(AMER GEOPHYSICAL UNION, 1997-01-20)Current understanding of the long-term ozone trends is described. Of particular concern is an assessment of the quality of the available measurements, both ground and satellite based. Trends in total ozone have been ...
-
(KLUWER ACADEMIC PUBL, 1993-01)Santiago is a city of over 4.5 million inhabitants and about 415000 motor vehicles using leaded gasoline. Twenty-four-hour samples were taken of total and fractionated particulate matter using a low-volume system and two ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 1995-07)This is a first-approach study tending to correlate solar radiation and temperature with total particulate matter in Santiago, Chile, a city heavily polluted by this contaminant. Experimental data for monthly average total ...

(ELSEVIER SCIENCE BV, 1993-11-15)A continuous-flow sensor based on integrated separation and spectrophotometric detection was developed for the determination of sulphur dioxide at the ng ml-1 level by transient immobilization of the reaction product formed ...
-
(TAYLOR & FRANCIS LTD, 1993)We present the synthesis and a description of the physical properties of several organic dyes containing stilbene as well as azomethine groups. The preparations of all compounds started from a common precursor, ...
-
(GORDON BREACH SCI PUBL LTD, 1996)Structural investigations using X-ray diffraction on methacrylate and acrylate based polymers with different side-chain mesogenic units are presented. The measurements were carried out by means of diffractometers with one ...

(ELSEVIER SCI LTD, THE BOULEVARD, 2001-07-12)Sucrose forms a dicationic complex with cobalt(III)bis(phenanthroline) which can be isolated as the sparingly water-soluble triiodide salt or the water-soluble chloride. The circular dichroism (CD) spectrum demonstrates ...
-
(SOC STUDY REPRODUCTION, 2003-06)We studied the effects of a chronic intermittent cold stress regime on sympathetic nerve activation and ovarian physiology. This paradigm (4degreesC for 3 h/day, Monday-Friday, for 3 or 4 wk) does not affect basal plasma ...
-
(MOSBY-ELSEVIER, 2011-05)Background The small guanosine triphosphatase Rho and its target Rho-kinase have significant roles in experimental remodeling and ventricular dysfunction, but no data are available on Rho-kinase activation in patients with ...
