The Intermediate Data Structure (IDS) is a standardised database structure for longitudinal historical databases. Such a common structure facilitates data sharing and comparative research. In this study, we propose an extended version of IDS, named IDS-Geo, that also includes geographic data. The geographic data that will be stored in IDS-Geo are primarily buildings and/or property units, and the

Aim: This thesis serves two purposes. First, it informs specialists in global public health to consider a broader spectrum of pediatric disease. Second, it informs specialists in pediatric hospital care of how the feasibility of their clinical practice depends on a functioning health care system. Methods: The papers contextualize pediatric disease entities that so far have received relatively sp

Background noise and room acoustics may impede social interactions by interfering with oral communication and other cognitive processes. Accordingly, recent research in school environments has showed that social relationships with peers and teachers are described more negatively in rooms with long reverberation times (RT). The purpose of this study was to investigate how RT and hearing ability (i.

Abstract in Undetermined Background: The performance of glaucoma diagnostic systems could be conceivably improved by the integration of functional and structural test measurements that provide relevant and complementary information for reaching a diagnosis. The purpose of this study was to investigate the performance of data fusion methods and techniques for simple combination of Standard Automate

To validate cardiac output measurements by ultrasound dilution technology (COstatus monitor) against those obtained by a transit-time ultrasound technology with a perivascular flow probe and to investigate ultrasound dilution ability to estimate pulmonary to systemic blood flow ratio in children.

Boronate-containing thin polyacrylamide gels (B-Gel), polymer brushes (B-Brush) and chemisorbed organosilane layers (B-COSL) were prepared on the surface of glass slides and studied as substrates for carbohydrate-mediated cell adhesion. B-COSL- and B-Brush-modified glass samples exhibited multiple submicron structures densely and irregularly distributed on the glass surface, as found by scanning e

To test the hypothesis that dissolved organic nitrogen (DON) is important for sustaining primary production by the microphytobenthos (MPB) in nitrogen-limited conditions, we measured the uptake of (15)N-labelled urea, the amino acids glycine (GLY) and glutamic acid (GLU), and nitrate and ammonium under simulated in situ light and temperature conditions. Microphytobenthic primary production and chl

We consider the effect of signaling rate (baud rate) on the information rate of single carrier linear transmission systems with Gaussian inputs. Several different communication scenarios are investigated: correlated or uncorrelated symbols, a fixed modulation pulse or a modulation pulse varying with the signaling rate and frequency selective or flat channels. For uncorrelated symbols, we show that

Drawing upon Transition and Technological Innovation Systems' theory, the author analyzed the process by which the Nicaraguan electricity sub-sector transitions towards renewable energy generation, the actors and networks of actors that play central parts in this process, the regulatory infrastructure that frames actors' actions and the factors and mechanisms that drive and block technolog

Nanoteknik är ‘big business’. Stora summor pengar står på spel då detta innovativa teknikområde expanderar i snabb takt. Denna undersökning utgår från antagandet att ekonomiska intressen snarare än demokratiska värden och hållbar utveckling styr utvecklingen av nanoteknik i Sverige idag. Detta ses som problematiskt, och det övergripande målet är att föreslå alternativa principer för att styra utveNanotechnology is big business. With rapid innovation and expansion of the field, financial stakes are high. This study is based on the assumption that the development of nanotechnology in Sweden today is controlled by economic interests rather than democratic values and sustainable development. This is considered problematic, and the overall aim with this study is to propose alternative principle

Inhemsk mikroalg skapar hållbarhet genom kombination av produktion och vattenrening Genom att använda snabbväxande mikroalger i avloppsvatten för produktion av biomassa har vattnet renats och det enda som tillsätts är solljus och koldioxid. Denna metod möjliggör hållbar produktion av en rad produkter, däribland biobränslen, samtidigt som samhällstjänster såsom vatten- och luftrening utförs på köpAbstract A few local microalgae was isolated and cultivated in vertical column with artificial lighting in 12 h light cycles in wastewater at the local wastewater treatment plant. The growth of the algae strains was observed and the fastest growing (Scenedesmus sp.) was subsequently cultivated outdoors under natural sunlight. pH controlled CO2 input resulted in up to twice as high biomass product

The purpose of this study is an understanding of operator work in a production line and its connection and translation into simulation. A mapping of operator work in the production line was performed, after which tasks and were analysed for their relevance for simulation. A model draft was developed in the software FlexSim. The mapping and the derived model provides insight into operator work in t

Despite available vaccines, rotavirus (RV) gastroenteritis remains to be an alarming cause of under-five mortality, especially in developing countries. Research on RV has been limited by the lack of faithful in vitro models that mimic virus-host interaction and RV pathogenesis in the intestine. Most recently, adult stem cell-derived organoids have advanced the understanding of the cellular mechani

Syftet med denna avhandling är att undersöka diffusionen av den fjärde industriella revolutionen inom livsmedelsindustrin i södra Sverige. Intresset för begreppet Industri 4.0 har ökat stadigt sedan det infördes av den tyska regeringen 2011. Men diffusionen verkar låg. Om Industri 4.0 är en revolution är införandet av den nya tekniken avgörande för konkurrenskraften. Detta faktum har resulterat i The aim with this thesis is to investigate the diffusion of the fourth industrial revolution in the food manufacturing industry in southern Sweden (FMISS). The interest of the concept Industry 4.0 has increased steadily since the introduction by the German government in 2011. However, the diffusion seems slow. If Industry 4.0 is a revolution, adoption of the new technologies will be crucial for co

How we choose to invest in the future generations is becoming increasingly imperative as researchers learn more about the long-term consequences of early childhood. The early-life literature suggests that empowered mothers invest more into their children and that matrilineal females are more empowered than patrilineal counterparts. To further understand the role of female empowerment on early chil

Radiation protection is of importance for the general public, patients and personnel in many different situations: rare accidents involving ionizing radiation, medical examinations or work tasks in the medical clinic or nuclear industry to name a few. Optimization in radiation protection and limitation of radiation doses are essential to prevent overexposure and for reducing negative health conseq

Rainforests are of great importance for biodiversity and several ecosystem services. In Rwanda, a considerable decline in rainforest covers have been observed during the last decades. The Gishwati-Mukura Forest is one of the rainforests in Rwanda that has experienced a substantial reduction in forest cover, 99.4 %. The aim of this research has been to investigate what the changes in forest cover o
