Popular Abstract in Swedish Ta ett djupt andetag och tänk på vad du nu har i lungorna! Jo, det är luft, förstås, syre kväve och sådant. Men det är också något annat. I varje kubikcentimeter du andas in finns tusentals partiklar, alla för små för att kunna ses med blotta ögat. Om dessa partiklar handlar denna avhandling. Vi kallar luftburna partiklar för aerosoler, ett begrepp som innefattar allt Airborne particles are everywhere around us, and have always been. Particles generated by human activities has increased drastically since industrialization, and several epidemiological studies have shown that inhaled particles can cause adverse health effects. The concern about health effects have during the last decade shifted towards fine and ultrafine particles, not least due to the emerging f

Background: Body weight and body mass index (BMI) are positively related to risk of colon cancer in men, whereas weak or no associations exist in women. This discrepancy may be related to differences in fat distribution between sexes or to the use of hormone replacement therapy (HRT) in women. Methods: We used multivariable adjusted Cox proportional hazards models to examine the association betwee

Soil temperature fluctuations are typical at high latitudes in early spring or late autumn. Freeze-thaw cycles (FTCs) occur when the soil temperature fluctuates around 0°C, causing a change in the state of the soil solution. Due to climate change, FTCs are predicted to become more frequent and intense, especially in the Arctic, Antarctic, and cold temperate regions. In this study, two experiments

The Covid-19 pandemic is in multiple ways a new type of crisis. The virus outbreak has had a serious impact on global health and has caused an economic downturn that is heavily driven by the restrictions implemented to attenuate the health-crisis. Apart from affecting the mobility of individuals, these restrictions impose additional constraints that policy makers need to adhere to when conducting

This thesis explores the potential of Blockadia resistance, the resistance of frontline communities against fossil fuel extraction, for the climate justice movement. Driven by the need for alternative forms of climate action that address the root causes of climate change, this study examines if local fossil fuel resistance gives rise to a justice based environmentalism. The analysis is conducted o

Human trafficking is an exploitative crime occurring worldwide. According to the International Organization on Migration (IOM), research on human trafficking’s underlying causes is lacking; particularly the role of climate change and natural disasters. Environmentally displaced persons (EDPs) are vulnerable to human trafficking, but this connection is not widely understood. In order to contribute

We now have entered the Anthropocene. Humanity is the new geological force drastically changing the systems of the Earth. At least this is the story told by natural scientists. Social scientists are critical of this ‘natural’ narrative as it cannot deal with the social dimension of geological changes. This is problematic with regard to understanding the relation between social justice and ecologic

Over the past two decades, immigrant-receiving countries have been confronted with honour crimes. In a number of Western European countries, there have been cases of police failure to intervene in cases of honour crimes occurring in migrant communities. The authorities responses to honour crimes have consistently been inadequate, as they do not take victims of honour crimes seriously and fail to p

This is an outline of a new joint Lund-Stockholm six-year research program funded by the Riksbankens Jubileumsfond, addressing three themes: (1) transnational actors and the democratization of international institutions, (2) democracy and public-private partnerships in global governance, and (3) the democratic credentials of transnational actors.

Accurately reconstructing the rate of movement and extent of eolian dunes over thousands of years is a challenging endeavor. In this paper, we refine the methodology for utilizing lakes and bogs downwind of dune fields as precise recorders of past eolian activity. Sediment cores from two Allegan County lakes and one bog associated with dunes were studied to evaluate the importance of the various s

The usage of industrial robots for milling tasks is limited by their lack of absolute accuracy in presence of process forces. While there are techniques and products available for increasing the absolute accuracy of free-space motions, the mechanical weaknesses of the robot in combination with the milling forces limits the achievable performance. If the dynamic effects causing the deviations can b

Global climate policy negotiations have become increasingly complicated with the rise of the socalled emerging powers as they have seen both great economic growth and increased emissions of greenhouse gasses – yet they continue to hold a developing country, or non-Annex I, status under the UNFCCC, which determines their responsibilities for addressing the climate crisis. This thesis examines the

There have been several accounts of suicide attacks in the last few years; and although male attackers outnumber female attackers, the number of female suicide bombers has been on the rise. This thesis analyzes the motivation of Muslim female suicide bombers using Durkheim’s theory on suicide and society. Interviews with experts on suicide and radicalization were conducted to provide a perspective

The successive waves of violence since May 2012, have put Myanmar in the international spotlight. The crisis in the Rakhine state has quickly become a global concern broadly discussed in the media. This paper examines how the Rohingya crisis is framed in Burmese and Western news media agencies by comparing the media coverage by The Global New Light of Myanmar and The New York Times between 2017-08

Denna masteruppsats syftar till utvecklandet av en industriellt, fullskalig modell över en vattenreningsprocess som syftar till simultan sulfatreduktion och tungmetallåtervinning från processvatten vid gruvdrift. Den mängd sulfat som finns tillgänglig i lakvattnet, omvandlas till vätesulfid med hjälp av sulfatreducerande bakterier (SRB). Tungmetallerna återvinns genom selektiv utfällning med hjälpThis thesis treats the development of an industrial scale models of a wastewater treatment process aiming at reducing the sulfate and heavy metal concentration in the effluent water from mining processes. The sulfate present in the process water is reduced using sulfate reducing bacteria (SRB) while the heavy metals are recovered through selective precipitation using the hydrogen sulfide produced
