Water Exchange Mechanism of Tetraaquapalladium(II). A Variable Pressure and Variable Temperature Oxygen-217 NMR Study

Water exchange of square-planar Pd(H2O)42+ has been studied as a function of temperature (240 to 345 K) and pressure (0.1 to 260 MPa, at 324 K) by measuring the 17/O-FT-NMR line-widths of the resonance from coordinated water at 27.11 and 48.78 MHz. The following exchange parameters were obtained: k298ex = (560 ± 40) s−1, ΔH* = (49.5 ± 1.9) kJ mol−1, ΔS* = – (26 ± 6) J K−1 mol−1 and ΔV* = – (2.2 ± Water exchange of square-planar Pd(H2O)42+ has been studied as a function of temperature (240 to 345 K) and pressure (0.1 to 260 MPa, at 324 K) by measuring the 17/O-FT-NMR line-widths of the resonance from coordinated water at 27.11 and 48.78 MHz.

Rubus sect. Corylifolii in the province of Halland, SW Sweden

Abstract in UndeterminedAn inventory is described of Rubus sect. Corylifolii from the province of Halland in south-west Swe- den. About 850 localities have been visited and field studies have been combined with chromo- some counting and random amplified polymorphic DNA studies. Ten traditional species have been observed, as well as six local species, two with over70 localities each. The other four

Rubus sordirosanthus in Halland, southwest Sweden

Abstract in UndeterminedRubus sordirosanthus (sect. Corylifolii Lindl.) was published, although invalidly, by Hylander 1958 from the province of Halland, south-western Sweden. A holotype is here provided to make the name validly published. Recent field studies have shown that it occurs at almost 100 localities in a restricted area of c. 6 km around Steninge in central Halland. In addition, it is f

Swedish GDP 1300-1560 : A Tentative Estimate

This study presents a reconstruction of historical national accounts for Sweden 1300-1560. The source material for this period is very scanty and, therefore, many estimates and approximations were necessary. For agriculture the so called demand approach was used, implying utilization of price series and assumptions on price, income and cross elasticities. Furthermore, population figures had to be

The XXL Survey : VI. the 1000 brightest X-ray point sources

Context. X-ray extragalactic surveys are ideal laboratories for the study of the evolution and clustering of active galactic nuclei (AGN). Usually, a combination of deep and wide surveys is necessary to create a complete picture of the population. Deep X-ray surveys provide the faint population at high redshift, while wide surveys provide the rare bright sources. Nevertheless, very wide area surve

Är vetenskaplig grund och beprövad erfarenhet i skolan samma sak som vetenskap och beprövad erfarenhet i hälso- och sjukvård?

Begreppet ’vetenskap och beprövad erfarenhet’ har åtminstone sedan 1829 års licentiat- eller läkared spelat en framträdande roll inom svensk hälso- och sjukvård (Kock 1939, 281):Och som mig rättighet nu meddelas att utöfwa läkarekonsten, så will och skall jag i sjukdomars behandling endast anwända sådane medel, hwilka erfarenheten, wetenskapen och mogen pröfning godkänt, Bestämmelsen i dess modern
