Studies focusing on genetic and social influences on maternal adjustment will illumine mother's marriage, parenting, and the development of psychopathology in her children. Recent behavioral genetic research suggests mechanisms by which genetic and social influences determine psychological development and adjustment. First, heritable, personal attributes may influence individuals' relationships wi
In animal ethics animal capacity to suffer and experience is a selfevident point of departure when elaborating theories for respecting animals. Less often the practical consequences of "respecting an animal" is discussed in these theories, still they want to influence our behavior towards the animals. So, in order to know what is respectful, we need to connect scientific knowledge about an animal
The aqueous self-assembly of a novel lysine-derived surfactant with a gemini-like architecture, designated here as 12-Lys-12, has been experimentally investigated for the amphiphile alone in water and in a mixture with dodecyltrimethylammonium bromide (DTAB). The neat surfactant forms interesting micrometer-sized rigid tubules in the dilute region, resulting in very viscous solutions. For the cata
Sprickbildning i puts på isolering har inträffat i ökande omfattning på senare tid. I denna rapport redovisas resultaten från inledande studier på provväggar i laboratorium. Två provväggar, med respektive utan fönster samt med olika fasthållning, har studerats.
Time relations among trauma, pulmonary and systemic circulation, and lung function were studied in pigs. Eleven animals (b.w. 25-30 kg) were investigated under balanced anesthesia. Ventilation was mechanically controlled. Hemodynamics, pulmonary ventilation, and gas exchange were serially recorded. Seven animals were pretreated with 40% ethanol in saline and four with saline only. Ninety minutes a
Based on a physical understanding of phase-noise mechanisms, a passive LC filter is found to lower the phase-noise factor in a differential oscillator to its fundamental minimum. Three fully integrated LC voltage-controlled oscillators (VCOs) serve as a proof of concept. Two 1.1-GHz VCOs achieve -153 dBc/Hz at 3 MHz offset, biased at 3.7 mA from 2.5 V. A 2.1-GHz VCO achieves -148 dBc/Hz at 15 MHz
PURPOSE: To assess the clinical phenotype in a Swedish family with X- linked retinitis pigmentosa (XLRP) resulting from a novel splice defect in the RPGR gene. METHODS: RPGR mutation analysis was performed in one family with XLRP, and several individuals from the family were examined clinically. RESULTS: The causative mutation in the family was demonstrated to be a single base-pair change at the s
Background In vivo measurement of wear in the ball and socket articulation of total hip arthroplasties is of interest in the evaluation of both existing and new implants. Controversy reigns regarding the accuracy of different radiological measurement techniques and in particular how accuracy has been assessed. Material and methods We assessed the accuracy of 2 radiostereometric (RSA) techniques f
We have studied small InP quantum dots in a GaInP matrix theoretically and experimentally. Using low-temperature photoluminescence spectroscopy in conjunction with six band k.p calculations, including direct and exchange interactions, we show that the dot size is a crucial parameter that determines whether the dot is neutral or charged with electrons in the nominally undoped n-type host material.
This study of maxillary sinus reconstruction in conjunction with insertion of endosseous implants included 99 patients. Two separate surgical methods were applied; a one-staged strategy (n=49) and a two-staged strategy (n=50). The aims were to compare two different strategies concerning implant and prosthetic construction survival. Differences in positioning and angulation of the inserted implants
The Ikaros project started in 2001 with the aim at developing an open infrastructure for system-level brain modeling. The system has developed into a general tool for cognitive modeling as well as robot control. This report describes the main parts of the Ikaros system, in particular the simulation kernel, and summarizes the work done within the first five years of the project.
This paper concerns the history of medicine, particularly formal medieval medicine in the Islamic cultural sphere. It focusses on the 9th century physician Qusta ibn Luqa and his production, and includes a survey of the contents of a hitherto unpublished Arabic treatise, attributed to Qusta ibn Luqa, on dental-nerve dysfunction.
The aim of this dissertation is to examine the institutional changes which occurred in Chile under the military regime from 1973-1981, and how these changes can be related to subsequent economic development in the country. The empirical material comprises of an investigation of the new economic policy in the agricultural sector, the political process behind this policy and the social and economic
Popular Abstract in Swedish Avhandlingen behandlar användandet av faltnings koder och Turbo koder för felkorrigering i radio system. Design av koder, avkodare samt metoder för återtransmission behandlas, i syfte att förbättra trafikkapaciteten i digitala radionätverk. Mer specifikt diskuteras design av låg-takts Turbo koder för spritt-spektrum fleranvändarsystem, list sekvens avkodning av länkade New wireless services such as mobile Internet, multimedia streaming and high speed packet data access are making their way to the market. Availability of low-cost equipment providing high transmission quality and efficient spectrum utilization is crucial to the success of these services. This thesis is a collection of papers that address an important step in this direction: efficient error control
In this study, two different methods of estimating cell proliferation were compared: cell loss and potential growth rate of xenografted head and neck cancer grown in nude mice based on the detection of DNA incorporation of bromodeoxyuridine (BrdUrd) in one method, and [3H]thymidine ([3H]TdR) in the other. The 21-d-old xenografts were labelled in vivo, either with BrdUrd or [3H]TdR and excised at i
Photoinduced electron injection from the sensitizer Ru(dcbpy)2(NCS)2 (RuN3) into SnO2 and TiO2 nanocrystalline films occurs by two distinct channels on the femto- and picosecond time scales. The faster electron injection into the conduction band of the different semiconductors originates from the initially excited singlet state of RuN3, and occurs in competition with intersystem crossing. The rate
