End-to-side nerve repair in the upper extremity of rat.
The end-to-side nerve-repair technique, i.e., when the distal end of an injured nerve is attached end-to-side to an intact nerve trunk in an attempt to attract nerve fibers by collateral sprouting, has been used clinically. The technique has, however, been questioned. The aim of the present study was to investigate end-to-side repair in the upper extremity of rats with emphasis on functional recov
Can genital-tract human papillomavirus infection and cervical cancer be prevented with a vaccine?
Human papillomavirus (HPV) infection is the cause of squamous cell carcinoma of the uterine cervix. This causative relationship has provided the rationale and incentive for development of a prophylactic vaccine. Such a vaccine, if found to be effective, could reduce the need for cervical cancer screening and have a profound effect on the incidence of cervical and other anogenital cancers. This rev
Den rationella inbrottstjuven? : En studie om rationalitet och rationellt handlande i brott
Popular AbstractStudien behandlar temat rationalitet och bostadsinbrott. Ett syfte har varit att undersöka rationalitet och rationellt handlande. Rationalitetsbegreppet är komplext och diskuteras och definieras olika i litteraturen. Den teoretiska referensramen har utgjorts av rationalitetsteorier, främst de s.k. Rational Choice-teorierna. Den grundläggande betydelse som rationalitet fått i detta Rationality as purposive action among burglars is the theme of this study. Various theories concerning rationality, Rational Choice Theory especially, are discussed. The first purpose of this thesis is to highlight the concept of rationality. Rationality is a complex concept and it is defined in various ways in the literature. The basic definition is to act in a purposive way towards a defined goa
Ultrafast dynamics of singlet-singlet and singlet-triplet exciton annihilation in poly(3-2 '-methoxy-5 '-octylphenyl)thiophene films
Singlet-singlet (S-S) and singlet-triplet (S-T) exciton annihilation was studied in poly(3-2(')-methoxy-5(')octylphenyl)thiophene films. For the S-S exciton annihilation studies, transient absorption spectroscopy at excitation laser pulse fluences of 1.2x10(13)-4.4x10(14) photons/cm(2) and 2.5 kHz pulse repetition rate was applied. The obtained kinetics demonstrate a typical nonexponential charact
Design of a reverse osmosis plant for leachate treatment aiming for safe disposal
Leachate treatment is one of the major environmental issues faced by landfill owners. One promising method for reduction of pollutant discharge is reverse osmosis (RO). RO technology was tested at a pilot plant at Hedeskoga Landfill in southern Sweden. This landfill receives municipal solid waste (MSW) and industrial, commercial and institutional (IC&I) waste, and produces about 3000 m3/ha of

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

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
