In our society, digital cameras are used for a countless number of different purposes. There are many components going in to making such a complex product but one could argue that the camera sensor and lens make out the heart of a digital camera. Axis Communications AB, founded in 1984, is a Swedish company which pioneered and specialize in digital network cameras. In 1996 Axis delivered the first
This master’s thesis focuses on pedagogy and aspects of learning and remembering within guided museum tours for people with dementia. We explore in what way learning and remembering are focused on and triggered during those tours and with the help of which pedagogical means. Furthermore, we discuss what place these tours have within the museum as an institution. In order to examine our questions a
This thesis analyses web statistics belonging to a national B2C e-commerce in retail. The purpose of the thesis is to investigate abandoned carts amongst logged in customers with at least one product added in to their cart and at least one visit to the payment page. Since the response variable "cart" is binary and we are studying the probability of a cart being abandoned, the suitable me
Punktlighet och förseningar inom järnväg är något som står högt upp på agendan i dagens samhälle. Med en infrastruktur som är i ett stort behov av underhåll samtidigt som trycket på klimatsmarta transportlösningar bara ökar, blir punktligheten och framkomligheten inom järnvägen avgörande. Med en total punktlighet på ungefär 90% finns det mycket att göra. En av järnvägens infrastrukturproblem är spPunctuality and delays within the railway system are of utmost concern in today’s society. With an infrastructure in a dire need of maintenance and the increasing pressure for environmentally friendly transportation solutions, punctuality and accessibility within the railway system becomes crucial. With an overall punctuality rate of approximately 90%, there is much to be improved. One of the prob
In Europe, willow (Salix spp.) trees have been used commercially since the 1980s at a large scale to produce renewable energy. While reducing fossil fuel needs, growing short rotation coppices (SRCs), such as poplar or willow, may have a high impact on local air quality as these species are known to produce high amounts of isoprene, which can lead to the production of tropospheric ozone (O3). Here
With the increased availability of computational resources, the past decade has seen a rise in the use of computational fluid dynamics (CFD) for medical applications. There has been an increase in the application of CFD to attempt to predict the rupture of intracranial aneurysms, however, while many hemodynamic parameters can be obtained from these computations, to date, no consistent methodology
This dissertation deals with memory, recognition and solidarity in the Nowa Huta district of Kraków, Poland. Nowa Huta was founded as an independent, socialist model town in 1949, together with the large Lenin Steel Plant, and was incorporated into Kraków in 1951. In the 1980s the steel plant and district became one of the main centers of the oppositional Solidarity movement in Poland. Situated be
The objective of this thesis is to investigate the synthesis of well-defined polymer nanohybrid materials bearing desirable functionality via surface-initiated atom transfer radical polymerization (SI-ATRP) for potential bioapplications.SI-ATRP is an excellent controlled radical polymerization (CRP) method for the synthesis of polymer nanohybrid by growing polymer brushes (chains) from an interfac
Background: Prostate-specific antigen (PSA) measurement in midlife predicts long-term prostate cancer (PCa) mortality among white men. Objective: To determine whether baseline PSA level during midlife predicts risk of aggressive PCa in black men. Design, setting, and participants: Nested case-control study among black men in the Southern Community Cohort Study recruited between 2002 and 2009. A pr
Pulchrol, a natural compound isolated from the roots of the vegetal specie Bourreria pulchra has been shown to possess potential antiparasitic activity toward Trypanosomatids, particularly against Trypanosoma cruzi, which causes the Chagas disease; and moderately against Leishmania species, responsible for Leishmaniasis. In this investigation, several pulchrol analogues were prepared and assayed t
Acute myeloid leukemia (AML) is a highly heterogeneous blood disease which is characterized by different mutations and chromosomal rearrangements. Nearly 60% of genetic alterations have been found in AML patients involve in signaling pathways including signaling of tyrosine kinase receptor FLT3. FLT3 mutations emerged as one of the most common mutations in AML which represent around 35% of all AML
Inflammatory airway diseases and lower respiratory tract infections are leading causes of severe illness, disability and death worldwide. Much of today´s hypotheses about the underlying inflammatory processes and pathogenic contribution by immune cells come from in vitro experiments or animal models. As a consequence, our knowledge of the actual immunopathological events in real patient tissues is
Att mäta framgång i byggprojekt idag kan vara svårt. Dels att hitta en samsyn på vad framgång är dels hur man ska mäta framgång. Genom den forskning som finns inom området kan man konstatera att det är äldre metoder som används än idag för att mäta framgång. Dessa metoder har även modifierats med tiden och bildat nya metoder. De vanligaste områdena att mäta för att förstå framgång i forskning är tMeasuring success in construction projects today can be difficult—partly due to the lack of consensus on what success is, and partly due to the challenge of how to measure it. Existing research shows that older methods are still used to measure success, though many of these have been modified over time and evolved into new approaches. The most common aspects evaluated in research when measuring su
Radar data at C-band has shown great potential for the monitoring of soil and canopy hydric conditions of wheat crops. In this study, the C-band Sentinel-1 time series including the backscattering coefficients σ0 at VV and VH polarization, the polarization ratio (PR) and the interferometric coherence ρ are first analyzed with the support of experimental data gathered on three plots of irrigated wi
Moving from a fossil dependent to a fossil free economy requires increased energy production from renewable resources. This thesis discusses the utilization of agricultural waste streams, such as straw and manure, for biogas production. The first part of the research presented focuses on pretreatment of straw with the aim to reduce the handling issues concerning straw and improve the degradation o
Background: Intravesical instillation of bacillus Calmette-Guérin (BCG) is an accepted strategy to prevent recurrence of non–muscle-invasive bladder cancer (NMIBC) but associated with significant toxicity. Objective: NIMBUS assessed whether a reduced number of standard-dose BCG instillations are noninferior to the standard number and dose in patients with high-grade NMIBC. Design, setting, and par
Background: Cardiovascular autonomic dysfunction is a multifactorial disorder manifested as orthostatic hypotension (OH) and postural orthostatic tachycardia syndrome (POTS). OH has been associated with an increased risk of cardiovascular disease (CVD), and the underlying mechanisms are not fully understood and explored.Aims and methods: Project I: We aimed to discover protein biomarkers related t
