Thin films of (B4C)-B-10 have shown to be very suitable as neutron-converting material in the next generation of neutron detectors, replacing the previous predominantly used He-3. In this contribution we show under realistic conditions that (B4C)-B-10 films are not damaged by the neutron irradiation and interactions, which they will be exposed to under many years in a neutron detector. 1 mu m thic
A novel design approach to form macroporous gels is presented. Macroporous gels (MGs), known as cryogels(or gels prepared at subzero temperatures), were prepared inside a protective plastic core (so-called, housing), thus making them resistant to shear forces at stirring. MGs are highly elastic polymeric materials with pore sizes up to 100 mu m and spongelike morphology. Design of MGs inside a pro
Popular Abstract in Swedish Avhandlingen handlar om lungornas funktion hos för tidigt födda (prematura) barn med brist på surfaktant, ett ämne som normalt ska finnas i lungorna, och hur lungfunktionen hos sådana barn kan förbättras genom tillförsel av det saknade ämnet utifrån. I avhandlingen har också använts en djurmodell (för tidigt födda lamm) för att studera hur konstgjord andning vid födelseThe thesis investigates lung function and the effects of rescue surfactant treatment in mechanically ventilated preterm human infants with respiratory distress syndrome (RDS), and the effects of ventilation at birth on the response to surfactant supplementation in preterm lambs. To assess lung function, the author recorded static pressure-volume (P-V) curves during passive deflation from total lun
Control beliefs, i.e. a person's perceived control over his or her own behaviour, are important predictors of psychological functioning in old age. The aim of this study is to examine the mediating effect of housing-related control beliefs on the relationship between housing accessibility and independence in activities of daily living (ADL). Moreover, cross-national differences in five European co
Abstract in UndeterminedThe effects of harvesting on the long-term mass balances of calcium (Ca), magnesium (Mg) and potassium (K) were evaluated on a regional level in Sweden. A new high-resolution weathering database was used together with estimates of total deposition, losses through harvest and leaching. Estimates were made for pine and spruce separately and for two harvesting intensity scenar
Objectives To investigate outcome after septal myectomy and to evaluate long-term hemodynamics with exercise echocardiography. Methods This study included 40 consecutive patients operated with septal myectomy for hypertrophic obstructive cardiomyopathy from January 1998 to August 2017 at Skane University Hospital, Lund, Sweden. Perioperative clinical data and echocardiography measurements were rev
Arctic archaeologists generally accept that Dorset Paleo-Inuit (Tuniit) (c. 800 BC-1300 AD) toolkits exhibit high levels of typological uniformity across Arctic Canada and Greenland. This understanding implies that the artifacts were likely produced according to a standardized set of practices that were somehow ÷einforced over time and shared across the isolated sites and communities inhabiting th
The radiotherapy workflow for prostate cancer is associated with systematic uncertainty stemming from the registration between the computed tomography (CT) and magnetic resonance (MR) images. A radiotherapy workflow based solely on MR imaging (MRI), called an MRI-only workflow, has been suggested as a means of eliminating this uncer¬tainty. The aim of the work presented in this thesis was to valid
The study investigates the relationship between drought and vegetation variations in three main basins of western and southwestern of Iran, using the comprehensive approach of time-series analysis, Standardized Precipitation Index (SPI), and anomaly calculation. A total of 30 ground stations’ daily meteorological data and the MODIS 16-day composite NDVI products (2000–2017) were used in this case.
This thesis consider the improvement of the simulation tools used to describe high energy particle collisions. These simulation programs are normally referred to as event generators. The emphasis is on two specific parts of the event generation: the introduction of radiation of weak bosons associated with the collision and a new model for colour reconnection. Each collision contains significant
Multi-antenna design in compact mobile handsets at frequency bands below 1 GHz is very challenging, since severe mutual coupling is commonly induced by simultaneous excitation of the chassis’ fundamental dipole mode by more than one antenna element. To address this problem, a novel multi-antenna design approach is proposed herein to obtain efficient and uncorrelated antennas. By manipulating the c
Objectives To develop evidence-based European League Against Rheumatism (EULAR) recommendations for vaccination in patients with autoimmune inflammatory rheumatic diseases (AIIRD). Methods A EULAR task force was composed of experts representing 11 European countries, consisting of eight rheumatologists, four clinical immunologists, one rheumatologist/clinical immunologist, one infectious disease p
How can a small fire at a subcontractor in the USA lead to a multimillion dollar loss at a Swedish telephone company, and how can a single machine breakdown lead to a complete production stop at a production company? With today logistics and production trends, where terms such as Lean Production, Six Sigma, 5S, and World Class Manufacturing are used every day, production companies are introducing
Syftet med denna studie är att utöka kunskapen om fiolundervisning i grupp jämfört med enskild undervisning. Studien bygger på tidigare forskning inom instrumentalundervisning och erfarenheter som olika instrumentalpedagoger har av de två olika undervisningsmetoderna. I denna studie används aktionsforskning som metod. För att samla data har jag filmat fiollektionerna och gjort strukturerade reflekTitle: Violin teacher challenges - A study of violin teaching in a segregated area The purpose of this study is to expand the knowledge of violin teaching in groups versus one to one teaching. The study builds on previous research on instrumental teaching and experiences that different instrumental teachers have from the two different teaching methods.In this study I have used action research as m
Sepsis is a serious clinical syndrome and one of the most common causes of death. It is defined as a microbial invasion and excessive immune reaction. There is no common cure for sepsis, and mortality in sepsis is high and rises quickly, so it is important to start precise treatment quickly. Sepsis is, however, hard to diagnose, as it has no symptoms specific to it alone, and thus new ways to diag
In this study, Dissolved Organic Matter (DOM) quality was analysed through its optical properties. Samples from the estuarine waters of the Beagle Channel and oceanic ones of the Burdwood Bank were examined in order to understand how DOM quality was changing. The focus of the study was to determine whether the environmental variables or the microbial community were the main driver in DOM compositi
The Internet is a unique medium never before seen and its introduction is probably only rivalled by that of television. It is unique in the sense that every person connected to the Internet has the possibility of interacting with other people across the globe simultaneously. The tools introduced to facilitate this interaction are IP-addresses and domain names. Domain names are connected to the IP-
Hjärntumörer utgör omkring 2 procent av alla cancerdiagnoser och den vanligaste elakartade hjärntumörtypen är glioblastom (GBM). Patienter med GBM behandlas i dag med kirurgi, cellgifter och strålbehandling, men sjukdomen går sällan att bota och det krävs nya och mer effektiva behandlingsstrategier.I min doktorsavhandling har jag använt tre olika musmodeller, kallade GL261, KR158 och SB28, för attAdvances in surgery, chemo- and radiotherapy have only modestly improved survival rates of malignant brain tumor patients during the last decades. Emerging evidence suggests that an efficient treatment of malignant brain tumors will likely require the management of multiple aspects of tumor pathobiology in order to manipulate features as tumor heterogeneity and tumor immunosuppression. Immunothera
Vertebral compression fractures (VCFs) are common and indicate a high future risk of additional osteoporotic fractures. However, many VCFs are unreported by radiologists, and even if reported, many patients do not receive treatment. The purpose of the study was to evaluate a new artificial intelligence (AI) algorithm for the detection of VCFs and to assess the prevalence of reported and unreported
