This paper investigates the function of metal working fluid (MWF) emulsions in automotive industries in Sweden and looks at how the negative environmental and health impact of their use can be reduced through means of monitoring and system design. Major input to this study has been collected from several of the large companies in Sweden, through a literature review, interviews, questionnaires, fin
Avian blood parasites have been preliminarily studied in East Asia, but no data are available from long-term monitoring. The aim of this study was to evaluate the prevalence, genetic diversity, and temporal dynamics of Plasmodium, Haemoproteus, and Leucocytozoon in two passerine communities (one forest and one urban) in north China from 2008 to 2013, as well as the association between infected lin
Phosphine derivatives of alkylidyne tricobalt carbonyl clusters have been tested as catalysts/catalyst precursors in intermolecular and (asymmetric) intramolecular Pauson-Khand reactions. A number of new phosphine derivatives of the tricobalt alkylidyne clusters [Co(3)(mu(3)-CR)(CO)(9)] (R = H, CO(2)Et) were prepared and characterised. The clusters [Co(3)(mu(3)-CR)(CO)(9-x)(PR'(3))(x)] (PR'(3) = a
Previous studies have suggested that amplification of genes, notably the TOP2A gene, on chromosome arm 17q may be important for the development of malignant peripheral nerve sheath tumour (MPNST). In order to study the frequency, distribution, and chromosomal organization of rearrangements at 17q, interphase and metaphase fluorescence in situ hybridization (FISH) were used to evaluate copy number
By emphasising the involvement of elderly people in a project applying a mixed-method approach, the overriding objective of this study was to identify and prioritise concrete measures aimed at increasing accessibility and safety in the outdoor pedestrian environment within a residential area of a Swedish town. Measures generally given priority were: the separation of pedestrians/cyclists, lower sp
Based on the body of evidence implicating ocular blood flow disturbances in the pathogenesis of glaucoma, there is great interest in the investigation of the effects of antiglaucoma drugs and systemic medications on the various ocular vascular beds. The primary aim of this article was to review the current data available on the effects of antiglaucoma drugs and systemic medications on ocular blood
Purpose – This paper aims to contribute to the tactical and operational decision making of manufacturing and logistics operations by providing novel insights into modelling and simulation, based on complex adaptive systems (CAS). Design/methodology/approach – The research approach is theoretically based on CAS with agent-based modelling (ABM) as the implementation method. A case study is presented
The cost of energy for drying paper is substantial for the pulp and paper industry, and studies of various strategies for energy cost reductions such as increased energy efficiency, increased heat recovery from the exhaust drying air and reduced cost of the process heat are presented in this thesis. The energy use and cost studies were performed using a block-model based simulation tool developed
This thesis is based on four papers (A-D) treating filtering, smoothing, and maximum likelihood (ML) estimation in general state space models using stochastic particle filters (also referred to as sequential Monte Carlo (SMC) methods). The aim of Paper A is to study the bias of Monte Carlo integration estimates produced by the so-called bootstrap particle filter. A bound on this bias which is inv
Pressure transduction to the wound bed in negative pressure wound therapy (NPWT) is crucial in stimulating the biological effects ultimately resulting in wound healing. In clinical practice, either foam or gauze is used as wound filler. Furthermore, two different drainage techniques are frequently employed. One involves the connection of a non-perforated drainage tube to the top of the dressing, w
Sierra Leone has struggled with high rates of adolescent pregnancy for some time and reports have shown an increase in these figures during and following the unprecedented Ebola Virus Disease outbreak from 2014 through 15. As young girls are impregnated, it has long been customary for girls to drop out of school. When schools re-opened after the Ebola crisis, this practice was formalized as the Mi
The textile industry, dominated by fast fashion, has caused significant environmental and social harm. Its complex global long supply chains, spanning multiple countries and production steps, increases the challenges related to traceability, transparency, and accountability. To address these issues, the European Union has introduced the Ecodesign for Sustainable Products Regulation (ESPR), which w
The growing use of economic sanctions as a foreign policy tool has intensi-fied legal and political tensions in the international trade system. This trend has been particularly pronounced following the expansion of the United States’ (U.S.) secondary sanctions with extraterritorial reach, and in response to major geopolitical events, including the U.S. withdrawal from the Joint Comprehensive Plan
This report evaluates a newly made investment in FIB, First Response Crew manager in Medelpad´s Rescue service Association (MRF). The focus is to by interviews and statistics present a picture of the current situation of how well FIB is working. The results of the interviews were categorized into different themes from which the results were later discussed together with the results from the statis
Lake Victoria is Africa’s largest freshwater lake by area shared by three countries: Uganda, Kenya, and Tanzania. The lake supports the economic development of the region through transport and fishing as well as recreational and tourism activities in the three countries. The main ports on the lake are Kisumu, Mwanza, Bukoba, Entebbe, Portbell, and Jinja served by several train ferry services for b
The Andes of Ecuador are known for an outstanding biodiversity but is also a region where the abandonment rate of agricultural land is high, highlighting the need for forest restoration with native species. Here, the germination and growth requirements for propagation of the hummingbird pollinated bush species Salvia corrugata and Macleania rupestris were studied to better understand their suitabi
The study of home has historically been approached by numerous academic disciplines within the social sciences and humanities. However, increased international mobility and forced migration due to conflict in recent years has produced a renewed interest to understand the ways we conceptualize and (re)create home in foreign places. The present research aims to produce a theoretical framework that a

Setting Four maternity hospitals in La Paz and El Alto, Bolivia, where free maternal health care is provided through a government-subsidised programme. Population All maternal deaths and women with near-miss morbidity. M
