Nalkas psykologin människan från fel håll?
Does psychology approach personality from the wrong direction? The present text argues that conventional personality psychology, spproaching its object of study from "above", i.e., mapping out the individual´s consciously held attitudes and view of him-/herself, has chosen the wrong path to a tenable science of personality. The alternative would be to scrutinize the processes by which the perceive
Dispersive effective material parameters
The author studied how effective material parameters call be defined for Maxwell's equations when taking dispersion into account. The reasoning is based oil the concept of dispersion relations, and is consequently primarily concerned with lossless media. The author essentially required that the effective material parameters should produce the same dispersion relations as the heterogeneous problem,
Use of history science methods in exposure assessment for occupational health studies
Aims: To show the power of history science methods for exposure assessment in occupational health studies, using the dry cleaning industry in Denmark around 1970 as the example. Methods: Exposure data and other information on exposure status were searched for in unconventional data sources such as the Danish National Archives, the Danish Royal Library, archives of Statistics Denmark, the National
Peak power reduction for OFDM systems with orthogonal pilot sequences
In this paper, a novel peak-to-average power reduction approach for orthogonal frequency division multiplexing (OFDM) has been addressed. Two-dimensional pilot-symbol assisted modulation (2D-PSAM) is employed in coherent OFDM for channel estimation, and it is based on inserting known symbols spread throughout the 2D time-frequency grid. These pilot symbols are employed to simultaneously perform di

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
