Populärvetenskaplig sammanfattning I dagens samhälle används diverse katalysatorer i många sammanhang för att påskynda kemiska reaktioner. Allt från produktion av ammoniak till rening av avgaser hjälps av olika katalysatorer. De katalysatorer som vi känner idag har tagits fram genom att testa olika materialkombinationer och utvecklingen har börjat stagnera. Enzymerna i våra kroppar är naturliga kA new instrument for near ambient x-ray photoelectron spectroscopy investigations of surfaces has been installed at beamline I511 of the MAX-II electron storage ring at the MAX IV Laboratory. This high pressure x-ray photoelectron spectroscopy instrument is capable of surface chemistry investigations in near ambient pressures using x-ray photoelectron spectroscopy (XPS), a technique that tradition

Studiens syfte är att undersöka och diskutera vem som har makten över vad som publiceras i medierna, och hur andra aktörer kan påverka medieagendan. Genom att studera strategin bakom en PR-kampanj vill vi bredda kunskapen och öka förståelsen för denna makt i allmänhet och nyhetsvärdering i synnerhet. PR-kampanjer kan ses som en marknadsföringsstrategi som genom att vara uppseendeväckande skapar si

The thesis deals with matters relating to neglected diseases and the lack of pharmaceutical R&D for the same diseases. Everybody is entitled to the right to health and subsequently the right to access to medicines, however not everyone has been receiving the benefits of this right. Currently there is an unsatisfying market-driven system, that can be changed by new and innovative approaches, su

The parts concerning victims of prostitution and the victims of trafficking in two Swedish Government Official Reports are in this essay compared to evoke the differences between the perception of the crimes and it’s victims. The method of the analysis is principally focused on the content and finds traction with a subsequent comparison to discover differences and similarities. The theory is based

With increasing migration to urban areas, Kenya is a country in change with new and challenging problems. Nairobi has a high population growth but a far from equal socio-economic development. As Nairobi continues to grow, so do the slum areas within the city and the slum Kibera has grown to be one of the largest in Africa. Due to the large economic differences within Nairobi I suggest that some pe

There is a growing interest in and demand for supervision to support professional development in human service organizations. This study focused on clinical group supervision provided by social workers in health care to employees at a university hospital in southern Sweden. The aim of the study was to examine the relation between the significance of supervision to the employees, when it comes to d

The aim of this masters’ thesis is to examine how libraries can better services for patrons with invisible disabilities. My hypothesis is that although libraries are legally obliged to pay special attention to persons with disabilities, in reality the special needs of persons with invisible disabilities are often ignored. Invisible disabilities are disabilities that are not immediately apparent. T

Denna studie avser att undersöka vilket mått, resultat eller operationellt kassaflöde, som bäst förklarar ett företags aktiekursutveckling samt hur denna förklaringsgrad förändras då tidsintervallen ökar. Studien omfattar 90 svenska bolag noterade på OMX Stockholm över tidsperioden 1997-2012. Undersökningen finner att operationellt kassaflöde förklarar variansen i aktieavkastning på Stockholmsbörs

This thesis aims to examine how the newspaper Dagens Nyheter portrayed the risk groups of HIV/AIDS. There was a constant categorization of these risk groups in Swedish news reports. The material used for this thesis are newspaper articles from January to June in 1985. The time-frame chosen is motivated because it was a crucial time in Swedish society, only three years after the first case of HIV/A

Silver in the form of nanoparticles has increasingly been used as an antibacterial component in consumer products over the last decade. The most common use of nanosilver is in sports clothing. A study has shown that 10-98% of the silver is washed out after 10 washes, which in itself could question the use of the silver. Generally the marketing from companies producing nanosilver products are vague

Genomgående ämne för denna uppsats är ansvar för andra. I en näringsverksamhet uppkommer flera situationer där det, för näringsidkarens del, kan bli tal om ansvar för någon annan. Ett sådant ansvar, i denna uppsats kallat ”utsträckt ansvar” eller ”kedjeansvar”, innebär att näringsidkaren kan bli ansvarig för någon annans agerande. Uppsatsen ämnar klarlägga huruvida det föreligger gemensamma grund

Handwriting is an important component of academic curricula and grapho-motor skills (GMS) support learning, reading, memory and self-confidence. Teachers and clinicians report increase in children experiencing problems with acquiring fluid and legible handwriting. To date gold-standard tests evaluating children's GMS, mostly rely on pen and paper tests, requiring extensive coding time and subject

This chapter provides conceptual and empirical foundations for smart specialization, a policy approach of far-reaching importance in the European context. We interpret the very notion as “diversified” specialization into areas of existing or potential competitive advantage, which differentiates a region/nation from others. “Smart” relates to the identification of these areas through a process of e

In this thesis, we focus on the problem of estimating receiver and sender node positions given some form of distance measurements between them. This kind of localization problem has several applications, e.g., global and indoor positioning, sensor network calibration, molecular conformations, data visualization, graph embedding, and robot kinematics. More concretely, this thesis makes contribution

MHC genes are extraordinarily polymorphic in most taxa. Host-pathogen coevolution driven by negative frequency-dependent selection (NFDS) is one of the main hypotheses for the maintenance of such immunogenetic variation. Here, we test a critical but rarely tested assumption of this hypothesis—that MHC alleles affect resistance/susceptibility to a pathogen in a strain-specific way, that is, there i

Aim: Risk of treatment-related life-threatening toxicity is high in childhood acute myeloid leukaemia (AML), and access to intensive care units (ICU) is crucial. We explored the ICU admission rate and outcome after intensive care in childhood AML in Sweden. Methods: Patients diagnosed between 2008 and 2016 were identified from the Swedish Childhood Cancer Registry (SCCR), a national quality regist

Lactose plays a significant role in daily lives as a constituent of various food and pharmaceutical products. Yet, lactose intolerance conditions demand low-lactose and lactose-free products in the market. These increasing nutritional claims and labels on food products entail simple and reliable methods of analysis that can be used for meeting quality standards, nutritional claims and legal requir
