Popular Abstract in Swedish Denna avhandling baseras på studier av de provtagningscykloner vilka används vid yrkeshygienisk provtagning av respirabelt damm i Sverige och andra andra länder i Europa. Målsättningen för arbetet har varit att avgöra huruvida cyklonernas mätvärden är valida relativt internationella provtagningskonventioner för respirabelt damm, samt eventuellt förbättra deras överensstThe performance of cyclones used in occupational hygiene for sampling respirable dust was studied. Test methods for experimental determination of cyclone penetration have been designed and validated. The penetration curve for a sampling cyclone presently used in Europe was measured. The sampler's performance relative to three sampling conventions for respirable dust was determined. The cyclone was

One of the most promising and critical application of vehicular ad hoc networks (VANETs) is improvement of the road traffic safety. Currently there is a growing belief that putting an 802.11-like radio into road vehicles could help the drivers to travel more safely. Although research in this field is in preliminary stage, some simple implementations are quite promising; to the best of our knowledg

In order to evaluate three common human papillomavirus (HPV) DNA tests for key performance indices in population-based cervical screening, we sampled 12,527 women aged 3238 years who attended invitational, population-based screening and followed them for 4 years with comprehensive registry linkages. Three different HPV DNA tests (GP5+/6+general primer PCR (using either AmpliTaq or AmpliTaq Gold DN

The main objective of this paper is to demonstrate how greenhouse gas (GHG) emissions can be quantified during the evaluation of control strategies in wastewater treatment plants (WWTP). A modified version of the IWA Benchmark Simulation Model No 2 (BSM2G) is hereby used as a simulation case study. Thus, the traditional effluent quality index (EQI), operational cost index (OCI) and time in violati

The aim of this thesis was to reconstruct the glaciodynamics, deglacial landforms, isostatic uplift and to date the deglaciation. Glaciodynamics and deglacial landforms were focused on to provide a process and depositional model for De Geer moraine and Niemisel moraine and to reveal their internal and spatial relationship, based on detailed sedimentological and structural investigations. The isost

Photosynthetically Active Radiation (PAR) is important for assessing both the impact of changing land cover on climate, and for modelling productivity on a regional scale, as well as its potential in areas that are vulnerable to food shortfalls. A relatively simple method that generates spatially comprehensive and representative values of PAR at time scales of 10-days (dekads) or longer is describ

Pressure on consumer goods manufacturers to develop new products with significantly less environmental impact is growing, through increased consumer awareness of environmental issues and governments setting ambitious emissions reductions targets. A strategic response to this pressure is to prepare a portfolio of innovative product ideas to meet a range of future emissions reductions targets. Howev

Understanding the molecular mechanisms behind beta cell dysfunction is essential for the development of effective and specific approaches for diabetes care and prevention. Physiological human beta cell models are needed for this work. We review the possibilities and limitations of currently available human beta cell models and how they can be dramatically enhanced using genome-editing technologies

To contribute to contemporary rural development debates, the present thesis conducts a contextual analysis of rural development using Kenya as a case study from the colonial era to today. To perform the analysis, two critical trends in rural Africa are focused on: socioeconomic differentiation and rural income diversification, with a particular focus on large-scale farm employment. By pointing to

The objective of this study was to critically assess and review empirical evidence on the cost-effectiveness of Mobile Health (mHealth) interventions for older adults. We systematically searched databases such as Pubmed, Scopus, and Cumulative Index to Nursing and Allied Literature (CINAHL) for peer-reviewed economic evaluations published in English from 2007 to 2018. We extracted data on methods

When we develop general-purpose robot software components, we rarely know the full context that they will execute in. This limits our ability to make predictions, including our ability to detect program bugs early. Since running a robot is an expensive task, finding errors at runtime can prolong the debugging loop or even cause safety hazards. In this paper, we propose an approach to help develope

Biochemical signaling is mediated by complexes between macromolecular receptors and their ligands, with the duration of the signal being directly related to the lifetime of the ligand-receptor complex. In the field of drug design, the recognition that drug efficacy in vivo depends on the lifetime of the drug-protein complex has spawned the concept of designing drugs with particular binding kinetic

Human communication is by default polysemiotic: it involves the spontaneous combination of two or more semiotic systems, the most important ones being language, gesture, and depiction. We formulate an original cognitive-semiotic framework for the analysis of polysemiosis, contrasting this with more familiar systems based on the ambiguous term "multimodality."To be fully explicit, we developed a co

A strategy for control of substrate feed rate in fed-batch fermentations is presented. The main idea is to make pulses in the feed rate and to evaluate the response in the dissolved oxygen signal. This gives an indirect measurement of the substrate demand that is used for feedback control of the feed rate. Experimental data is used to develop a model of a fermentation process. The model is used to

Matsvinn är ett stort samhällsproblem. Om förpackningen inte håller den nivå av kvalitet som krävs så slängs den under produktionen, tillsammans med det livsmedel den skulle skydda. Vissa förpackningar har korkar, som hjälper till att återsluta förpackningen. Om plasten i korken har fel egenskaper uppstår det ibland problem i produktionen. Detta projekt har tagit fram två sätt att undersöka plasteFood packages preserve foodstuff during storage. Some packages have caps, some of which have internal pull rings for easy removal of a membrane that extend the shelf life. The pull-rings are injection molded directly onto the package in the filling machine at the customer site. Any defect in the pull ring causes filled packages to be discarded at a significant cost to the supply chain. Some batche
