High plasma levels of oestrogens are associated with increased breast cancer risk. If smoking, as has been suggested, have both a tumour initiating mutagenic effect and a protective anti-oestrogenic effect, one would assume that smokers who give up smoking have the highest incidence of breast cancer. This was evaluated in the follow-up of a cohort of 10,902 women of whom 4,359 were premenopausal.
BACKGROUND: The changes of cancer incidence upon immigration can be used as an estimator of environmental influence on cancer risk. We studied site-specific liver and biliary cancers in first-generation immigrants to Sweden with an aim to search for aetiological clues and to find evidence for indigenous incidence rates. MATERIAL AND METHODS: We used the nation-wide Swedish Family-Cancer Database t
BACKGROUND: Immunosuppressive regimens with the fewest possible toxic effects are desirable for transplant recipients. This study evaluated the efficacy and relative toxic effects of four immunosuppressive regimens. METHODS: We randomly assigned 1645 renal-transplant recipients to receive standard-dose cyclosporine, mycophenolate mofetil, and corticosteroids, or daclizumab induction, mycophenolate
AIM: The present study examines the association between parity and survival following breast cancer diagnosis. METHODS: Medical records of 4453 women diagnosed with breast cancer in Malmö, Sweden, between 1961 and 1991 were analysed. All women were followed until 31 December 2003, using the Swedish Cause-of-Death Registry. Breast cancer specific mortality rate was calculated in different levels of
FN:s konvention om barns rättigheter fastslår att barn ska ses som fullständiga rättighetsbärare. När socialnämnden ansöker om tvångsvård med stöd av lagen (1990:52) med särskilda bestämmelser om vård av unga, LVU förordnas ett offentligt biträde åt barnet, som även blir barnets ställföreträdare. Det offentliga biträdet ska se till barnets subjektiva vilja och barnets objektiva intresse utifrån baThe UN Convention on the Rights of the Child states that children are holders of rights. When the social welfare committee apply for compulsory care under the Care of Young Persons act (LVU) a public counsel is appointed by the court. The counsel does not only become the child’s public legal representative, but also its children’s guardian, because of the lack of procedural capacity. The obligatio
The kinetics of the catalytic conversion of ortho- to parahydrogen was studied for the two catalysts, IONEX® and OXISORB®. The study also involved the optimization of an experimental technique for the conversion of orthohydrogen in a static setup. The main focus of the optimization being directed towards the analytical setup, where the acquisition of information and interpretation of the data were
The building sector is the largest contributor to greenhouse gas (GHG) emissions, primarily due to two factors: the embodied energy of construction materials and the operational energy consumed over a building’s lifespan. Given this substantial environmental impact, sustainability and climate resilience have become critical priorities in global policy frameworks. Addressing this challenge requires
The COVID-19 crisis introduced telecommuting and distance schooling into households all around the world. When national authorities enforced mitigation measures, they not only limited the spread of the disease, but also altered the lifestyle of many people. The joint effect of millions of people adapting to the new reality gave rise to an altered residential energy consumption pattern. Knowledge a
We analyse the effects of climate anomalies on women’s fertility in West Africa. We combine socioeconomic and fertility data from 10 rounds of Burkina Faso, Guinea, Nigeria and Mali ’s Demographic and Health Surveys and long-term high resolution spatial temperature and precipitation records to assess how women and households adapt their fertility preferences and births in response to exposure to l
We develop a general patch-use model of central place foraging, which subsumes and extends several previous models. The model produces a catalog of central place effects predicting how distance from a central place influences the costs and benefits of foraging, load-size, quitting harvest rates, and giving-up densities. In the model, we separate between costs that are load-size dependent, i.e. a d
We present a series of experimental results that disclose the crucial role of ionic strength and partial volume fractions in the control of the phase behaviour of binary protein mixtures. Our findings can be understood as that the ionic strength determines the relative contribution of the entropy of the protein counter-ions to the overall thermodynamics of the system. Associative phase separation
Forskning visar nu entydigt att den globala genomsnittstemperaturen stiger och att antropogena växthusgasutsläpp i stor utsträckning är orsaken till detta. Medan klimatförändringen är en global angelägenhet, är det också en fråga om stor orättvisa. De utvecklade länderna har generellt sett bidragit mest till klimatförändringarna, men effekterna kommer att bli värre för dem som har bidragit minst. Scientific findings now unequivocally show that the global average temperature is rising and that anthropogenic greenhouse gas emissions are largely responsible for this. While climate change is a global concern, it is also a concern of great injustice. Developed countries have generally contributed most to the climate changes, but the impacts will strike harder on those who have contributed least
The aim of this study is to estimate the average contribution of airborne particulate chemical substances in Falsterbo due to shipping emissions. Particularly the sulphate content will be analysed and its effect on both the environment and health will be discussed. The contribution was calculated using measurements in Falsterbo with a Soot Particle Aerosol Mass Spectrometer (SP-AMS) amongst other
There is an ongoing shift to mobility in business IT, as well as in the consumer space. Users do not demand mobile availability anymore, they simply expect the ability to access business IT with consumer devices. Stemming from this demand, mobile business intelligence (BI) has emerged as a response from the BI industry. Thus, mobile BI is an extension of traditional BI into mobile devices. In line
Wind power is subject to intensive research in the development of using more renewable energy. With a growing number of countries aiming at reducing carbon dioxide emissions, increasing investments are being made in wind turbines and wind farms. An intriguing option is to build large wind farms at sea. There are many challenges with building large offshore wind farms. This Master's thesis addr
This research paper seeks to provide a comprehensive understanding of the barriers hindering the integration of sustainability in construction companies, with a focus on understanding both internal and external barriers influencing this transition. Through the analysis of the viewpoints of various stakeholders, such as project managers, frontline employees, and business executives, this paper aims
This thesis studies the effects of Higher-Derivative Gravity, in an Effective Field Theory format, on the properties of a rotating black hole. In particular, it corrects the Einstein-Hilbert action with curvature invariants that contain six and eight derivatives. The resulting Equations Of Motion are first derived, and then solved with an ansatz that permits the study of black holes with an arbitr
