CCK regulates pancreatic enzyme secretion via short duodenal-pancreatic reflexes in pigs
Background: Different routes of administration of CCK-33 and blockage of CCK-A and muscarinic (m(3)) receptors are used in this study to evaluate the mechanisms by which cholecystokinin can stimulate the exocrine pancreas. Methods: The experiment was performed on eight anaesthetized pigs during control conditions and after administration of the CCK-A and m(3) receptor antagonists, Tarazepide and 4
Analysis of some heat exchanger concepts for use as gas turbine intercoolers
Endogenous substrates utilized by rat brain in severe insulin-induced hypoglycemia
Several previous studies have demonstrated that severe hypoglycemia is accompanied by consumption of endogenous brain substrates (glycolytic and citric acid cycle metabolites and free amino acids) and some have shown a loss of structural components as well, notably phospholipids. In the present study, on paralysed and artificially ventilated rats, we measured cerebral oxygen and glucose consumptio
Amperometric detection of mono- and diphenols at Cerrena unicolor laccase-modified graphite electrode: correlation between sensitivity and substrate structure
Graphite electrode modified with laccase from Cerrena unicolor served as a biosensor for detection of 30 phenolic compounds with different structures. Some correlations of the sensor response to the structures of substrates are discussed. This biosensor responded to: (i) nanomolar concentrations of some of the selected phenolic compounds, e.g., 2,6-dimethoxyphenol,coniferyl alcohol, caffeic acid,
Letters of a Learned Lady : Sophia Elisabeth Brenner's Correspondence, with an Edition of her Letters to and from Otto Sperling the Younger
Popular Abstract in Swedish Sophia Elisabeth Brenner (1659-1730) var Sveriges första stora kvinnliga poet. Hon var verksam som författare och lärd kvinna under femtio år, och var dessutom en flitig brevskrivare. Avhandlingen baseras på en inventering av bevarade brev till och från Sophia Brenner skrivna på latin, svenska, franska och italienska. Hennes nylatinska korrespondens med danske Otto SpeSophia Elisabeth Brenner (1659-1730) was Sweden's first great female poet, writing and publishing her poems over a period of fifty years. She was also, however, a prolific letter writer. The dissertation is based on an inventory of all the preserved letters to and from her written in Latin, Swedish, French and Italian. Her Neo-Latin correspondence with the Dane Otto Sperling the Younger is presen

Utbildningskontextens betydelse för lärandeprocesser
Popular Abstract in Swedish Denna avhandling handlar om betydelsen av kontexten för lärandeprocesser i datorstödd flexibel utbildning. Syftet är att utveckla kunskap om hur studerande i en gymnasieutbildning upplever och agerar i en datorstödd flexibel utbildningsmiljö och hur den upplevda kontexten påverkar de studerandes lärandeprocesser. En etnografisk ansats används och den innehåller teorier This thesis is about the importance of context to learning processes in computer-supported flexible education. The purpose is to develop knowledge about how students in an upper secondary class experience and act in a computer-supported flexible educational environment and how the experienced context affects the students' learning processes. An ethnographic application involving theories of learni
Ultra-wideband communication using hybrid matched filter correlation receivers
For ultra-wideband (UWB) communication, Rake receivers using matched filter detection show the best performance but they are complex to realize due to the inherent channel estimation problem and combining problem. Transmitted reference schemes, on the other hand, allow for a less complex receiver structure that is able to combine the energy from different multipath components without channel estim
Cutaneous field stimulation in the treatment of severe itch
OBJECTIVE: To evaluate the efficacy of cutaneous field stimulation of C fibers for the treatment of itchy skin and its effect on peripheral nerve fibers as shown in skin biopsy specimens. DESIGN: We conducted an open-label uncontrolled study of 19 patients with itching. Each patient applied a flexible plate containing electrodes to the itchy area for 20 minutes at a time once daily for 5 weeks to
Oscillator strengths and hypertine structures in GaII from multiconfiguration Dirac-Hartree-Fock calculations
We report relativistic multiconfiguration Dirac-Hartree-Fock calculations of oscillator strengths and hyperfine structures for a large number of electric dipole transitions in Ga II. Results for the 4s(2) S-1(0)-4s4p 3P(0)(o) hyperfine-induced transition are also given. Core polarization is accounted for by means of explicit CI. To describe spin and orbital polarization, which are important for th

A replicated quantitative analysis of fault distributions in complex software systems
To contribute to the body of empirical research on fault distributions during development of complex software systems, a replication of a study of Fenton and Ohlsson is conducted. The hypotheses from the original study are investigated using data taken from an environment that differs in terms of system size, project duration, and programming language. We have investigated four sets of hypotheses

High resolution laser fluorescence spectroscopy in the deep blue spectral region
High-resolution laser spectroscopy measurements have been performed in the wavelength region around 4000 Å using a pulsed dye laser acting on a collimated atomic beam. Extra-cavity Fabry-Pérot filtering was used to achieve a narrow line-width of the laser light. Isotope shifts were measured in the 4216 Å and 4202 Å rubidium lines with the result ?s(87, 85)=124.3(4)MHz, and?s(87, 85) = 124.2(7)MHz,
Future drugs for the treatment of benign prostatic hyperplasia.
For at least a decade, no new drug principles have been added to the therapeutic armamentarium for the treatment of lower urinary tract symptoms (LUTS) associated with or suggestive of benign prostatic hyperplasia (BPH). Theoretically, there seem to be several possibilities to improve the current treatment, which is based mainly on alpha1-adrenoceptor (AR) antagonists, 5alpha-reductase inhibitors
ACCURACY OF PROTEIN FLEXIBILITY PREDICTIONS
Protein structural flexibility is important for catalysis, binding, and allostery. Flexibility has been predicted from amino acid sequence with a sliding window averaging technique and applied primarily to epitope search. New prediction parameters were derived from 92 refined protein structures in an unbiased selection of the Protein Data Bank by developing further the method of Karplus and Schulz
Om mänskliga beslutsprocesser: Beslutskonflikt, en fråga om värderingar
How we initially formulate our decision problems may have a strong influence on our decisions and we often take the presented problems and alternatives for granted. When facing difficult decisions it is important to consider things as: ”am I considering the right decision”, ”are there other decisions with other alternatives that are more relevant”, etc. Also when considering a previously made deci
Requirements of Fire Resistance Based on Actual Fires (Swedish Approach)
A rational, analytical approach to a fire engineering design of load bearing steel structures is described. The method of design is directly based on the natural compartment fire concept and on strictly defined functional requirements and performance criteria. The method is permitted to be generally applied in Sweden, as one a1ternative;since more than ten years. For facilitating the practical app
Costing fixed assets in Swedish municipalities: Effects of changing calculation methods
When pricing public utility services Swedish municipalities are not allowed to charge more than their full cost. A dominant cost component in operations such as energy distribution or handling water and wastewater is the cost of fixed assets-depreciation plus interest, here referred to as "capital service cost" (CSC). The maximum acceptable price for the services is the full cost, i.e., variable c
