The synthesis and characterization of the title trisphenolate ligand are described. From its reaction with manganese(iii) three complexes were isolated. The crystal structures revealed one pentacoordinate monomer and two similar dimers with different solvents of crystallization. In the dimers the metal ions are hexacoordinate and connected through bridging of two phenolates. A combination of elect

We investigated the functional impact of a recently described islet-specific loss of sympathetic nerves that occurs soon after the autoimmune destruction of beta-cells in the BB diabetic rat (35). We found that the portal venous (PV) glucagon response to sympathetic nerve stimulation (SNS) was markedly impaired in newly diabetic BB rats (BB D). We next found a normal glucagon response to intraveno

Moths of Lobesia botrana (Lepidoptera: Tortricidae) are confronted with different volatiles emitted from the host plant during the different seasons. To test the hypothesis of plasticity of central plant odour processing in moths of different generations in the future, we first investigated the responses of antennal lobe (AL) interneurons of laboratory-reared virgin and mated males and females. We

In January 2004, Per Hall et al in an article in British Medical Journal stated that children under the age of 18 months, who underwent CT of the brain, could get negative effects on cognitive abilities in adulthood. At the Department of Radiology, Lund University Hospital, 55 children under the age of 18 months underwent CT of the brain during 2004 compared to 70 children in 2003. MRI of the brai

The purpose of the article is to describe and compare the purchasing process for advanced versus basic logistics services. Further some specific observations are presented from the procurement of advanced third-party logistics services, with respect to service definitions, providers evaluations and contracts. The purchasing process of logistics services will in the future need to be more different

In this paper algorithms for affine reconstruction from translational motion under various auto calibration constraints are presented. A general geometric constraint, expressed using the camera matrices, is derived and this constraint is used in a least square solution to the problem. Necessary and sufficient conditions for critical motions are derived and shown to depend on the knowledge of the i

Studies have shown that with the correct treatment the care of patients with hip fractures can be improved. Correct treatment can start in the ambulance and continue with good nursing care; by providing sufficient nutrition and minimizing the use of drugs; and through the prevention, early detection and treatment of postoperative complications such as decubital ulcers and delirium.

To investigate whether recurrent purulent otitis media results in permanent hearing loss, we studied 2 subgroups of children from a cohort, earlier prospectively followed from birth to the age of 3 years. One subgroup had recurrent acute otitis media (n = 12). and the other had no acute otitis media at all ("healthy" children; n = 21). At follow-up of these subgroups at the age of 10. no child had

Allozyme electrophoresis was used to investigate the structure of genetic variation in the rhizomatous coastal sedge, Carex arenaria, throughout its European range — from the SW Iberian peninsula to the Baltic region. Material was sampled from 77 sites in five geographic regions. Nine of the 13 investigated loci were polymorphic in the total material and there were interregional differences in the

The two main trade-offs considered determining reproductive patterns in iteroparous organisms are the one between current and future reproduction, and the one between the number and quality of offspring. Recently, it has been suggested that these trade-offs may be mediated by stress-induced reduction in immunocompetence. To test the hypothesis that stress reduces immune function, we investigated t

We are investigating a large number of Rydberg series of neutral calcium, with the help of the recently introduced Spline-Galerkin method. Perturbers belonging to the 4p2, 3d2, 3d5s and 3d4p configurations are investigated and their influence on different Rydberg series is discussed. Results are reported for members of different Rydberg series, with n up to 20-30, and compared with experiment and

A separation between mecA+ strains of Staphylococcus aureus and strains lacking mecA was achieved by the disk diffusion assay and the agar dilution method, utilizing disks containing 5 microg of oxacillin and inocula of approximately 5 x 10(5) CFU/spot, respectively, provided that agar with 0 to 0.5% NaCl and incubation at 30 degrees C were employed. The 5-microg oxacillin disks clearly discrimina
