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
The objective of the study was to examine the changes in central nervous system (CNS) activity and physical behaviour during induction and awakening from CO2 anaesthesia. Two studies, each using pigs immersed into 90% CO2 gas for a period of 60s were performed. In study 1, we monitored middle latency auditory evoked potentials (changes in latencies, amplitudes and a depth of anaesthesia index), el
A molecular test for Alzheimer's disease could lead to better treatment and therapies. We found 18 signaling proteins in blood plasma that can be used to classify blinded samples from Alzheimer's and control subjects with close to 90% accuracy and to identify patients who had mild cognitive impairment that progressed to Alzheimer's disease 2-6 years later. Biological analysis of the 18 proteins po
OBJECTIVES: To test a new delivery system for a telescopic stent-graft. MATERIALS: Variable overlap between the components of this stent-graft combination allows length adjustment. This device differs from other multi-component stent-grafts in that both components are contained within a single delivery system. METHODS: The stent-graft was implanted in the distal thoracic to suprarenal aorta of fiv
Human prostate is now considered a target for vitamin D receptor (VDR) ligands, such as BXL-628. Because BXL-628 inhibited prostate growth without interfering with androgen signaling, it represents a new option for benign prostate hyperplasia (BPH) therapy. However, BPH symptoms are related not only to prostate size, but also to compensatory bladder hypertrophy and eventual overactivity. We now re
Sex-allocation trade-offs have long been invoked as a primary factor underlying the evolution of separate sexes and the reduction of pollen production accompanying the evolution of selfing. In the present study, I conducted stamen and style removal experiments to explore the existence of such trade-offs in Nigella sativa, a hermaphroditic plant species whose flower structure allows early manipulat
The acyl-coenzyme A-binding proteins (ACBPs) contain 26 highly conserved sequence positions. The majority of these have been mutated in the bovine protein, and their influence on the rate of two-state folding and unfolding has been measured. The results identify eight sequence positions, out of 24 probed, that are critical for fast productive folding. The residues are all hydrophobic and located i
