The ability of dogs to adaptively modulate secretion by the exocrine pancreas to match changes in the amounts and sources of macronutrients is poorly understood. We evaluated the use of re-entrant pancreatic catheters as a non-terminal, temporary approach for the chronic collection of exocrine pancreatic secretion using unrestrained dogs fed diets differing in composition. Re-entrant catheters wer

A semiclassical description of structure functions in DIS at small x is presented. It gives an intuitive picture of the transition from the Double Leading Log approximation at large Q(2), to the powerlike dependence on x in the BFKL region at limited Q(2). Formal derivations from perturbative QCD, e.g. in the BFKL or the CCFM formalisms, are technically complicated, and therefore such an intuitive

The 6.4 T wavelength shifter at MAX-lab is a three pole superconducting planar wiggler with a warm bore, i.e. the vacuum tube passing through the wavelength shifter is at ambient temperature. The wavelength shifter, including surrounding systems such as power supply and He liquifier, has been assembled, tested, and commissioned at MAX-lab. The wavelength shifter has been installed into the 1.5 GeV

About the film Der Untergang.

C-stage effluent, E-stage effluent and a total effluent (C-stage and E-stage effluent mixed in proportion to the volumes of the effluents at the mill) have been treated with a ceramic microfilter membrane. The flux of the total effluent was considerably lower than of the separate effluents. The fluxes of the E-stage and C-stage effluents were 550 and 1,300 l/m2h, respectively, while the flux of th

Transport measurements are presented on a quantum ring that is tunnel-coupled to a quantum dot. When the dot is in the Coulomb blockade regime, but strongly coupled to the open ring, Fano line shapes are observed in the current through the ring, when the electron number in the dot changes by 1. The symmetry of the Fano resonances is found to depend on the magnetic flux penetrating the area of the

Calcium precipitation can have a number of effects on the performance of high-rate anaerobic performance including cementing of the sludge bed, limiting diffusion, and diluting the active biomass. The aim of this study was to observe the influence of precipitation in a stable full-scale system fed with high-calcium paper factory wastewater. Granules were examined from an upflow anaerobic sludge bl

A customized processor for real time image convolution has been designed to increase the performance of an instrument for automated cereal grain quality assessment. Image convolution requires an extensive amount of calculation capacity and a corresponding amount of data transfers, hard to achieve with standard processors in real time. Therefore, a tailored architecture with a streamlined dataflow

A farm systems mass-balance calculation model, FARMFLOW, was applied to a case study comparing organic and conventional management of a Swedish experimental dairy farm, Ojebyn. Parameterisation of the model is implemented using detailed field data from the Ojebyn farm where the two management systems have been run parallel for more than 11 years. Simulations were made to compare the stocks, flows

Objective-The objective of this study was to determine the conduction properties of the normal atrioventricular (AV) conduction system in relation to accessory pathway (AP) location in patients with symptomatic Wolff-Parkinson-White syndrome. Design-The conduction properties of the AP and the AV node were studied in 356 patients with single manifest AP who underwent successful ablation. Results-Si

We present a theory of the elementary spin excitations in transition-metal ferromagnet nanoparticles which achieves a unified and consistent quantum description of both collective and quasiparticle physics. The theory starts by recognizing the essential role played by spin-orbit interactions in determining the energies of ferromagnetic resonances in the collective excitation spectrum and the stren

Severe hypoglycemia was induced by insulin in lightly anaesthetized (70°o N2O) and artificially ventilated rats. Brain tissue was frozen in situ after spontaneous EEG potentials had disappeared for 5. 10. 15 or 30 min and cerebral cortex concentrations of labile organic phosphates, glycolytic metabolites, ammonia and amino acids were determined. In other experiments, recovery was induced by glucos

We have previously observed that pyridoxine treatment reduced plasma total cholesterol (TC) and low-density lipoprotein (LDL) cholesterol concentrations and increased antithrombin III (AT III) activity in atherosclerotic patients with subnormal plasma pyridoxal 5-phosphate (PLP) levels. In order to confirm these results, we selected 17 males with low plasma PLP levels from a group of 122 80-year-o

Mechanical signaling and BMP expression appear to be involved in controlling the differentiation of cartilage in fracture repair, but the connection between mechanics and BMP signaling is not known. In this study of rats, we used a bone chamber to see how BMP gene expression was changed by a mechanical loading regime that induces cartilage formation in this model. We compared the still undifferent

We explored the potential relationships between male traits, reproductive success, testosterone levels in the breeding season, and Immoral immunocompetence in male red-winged blackbirds (Agelaius phoeniceus). Males responded to a single injection of diphtheriatetanus vaccine by producing antibodies to both antigens. The primary responses to each antigen were positively correlated with each other,

Excited states in the very neutron deficient odd cadmium isotopes Cd-99, Cd-101 and Cd-103 are discussed in terms of the nuclear shell model. Systematics of excited states in Cd99-109 is presented.
