Risk assessment is a useful tool in ensuring the continuous operation of critical societal functions. It can be used on many levels of an organization or society. One way to conduct risk assessments on higher system levels is to aggregate risk information from lower-level assessments. However, the process of aggregating risk information can be complex and different strategies for such aggregation Risk assessment is a useful tool to inform decision-making when it comes to ensuring the continuous operation of critical societal functions. It can be used on many levels within an organization or on multiple societal levels. One way to conduct risk assessments on a higher system level, such as on national level, is to aggregate risk information from lower-level assessments, e.g. from the regiona

For well over a century, migration researchers have recognized the lack of adequate distance measures to be a key obstacle for advancing understanding of internal migration. The problem arises from the convention of spatially defining migration as the crossing of administrative borders. Since administrative regions vary in size, shape, and settlement patterns, it is difficult to tell how far moverFor well over a century, migration researchers have recognized the lack of adequate distance measures to be a key obstacle for advancing understanding of internal migration.

A shift in new venture creation can be observed from purely profit-oriented models to alternatives attempting to also answer social and environmental needs. Because of their nature, these alternatives face issues regarding their integration in traditional financial and business spheres. Shared Value Creation is a framework that attempts to analyse these ventures and those challenges. Blockchain te

Hur kan vår vattenanvändning bli mer hållbar? Hur kan vi minska vår förbrukning av dricksvatten? Med stigande temperaturer, klimatförändringar och ökande befolkning blir dessa frågor allt viktigare. Ett förslag är att dra ner på vår dricksvattenkonsumption genom att använda regnvatten. Regnvatten kan användas till att spola i våra toalettstolar, till tvättmaskiner och till bevattning. Men hur kan How can our water consumption become more sustainable? How can our consumption of drinking water decrease? With increasing temperatures, climate changes, and population growth the questions becomes more important. To address this, a suggestion of reducing our drinking water consumption by utilizing rainwater is proposed. Rainwater can be used to flush our toilets, to wash clothes, and for irrigati

Lund University is now taking the next step towards a more secure IT environment. To protect ourselves against today's increased threats, secure passwords alone are not enough; we also need strong authentication to log in to our IT services. Currently, this only applies to Lund University staff, not students.Strong authentication is a way of signing in to an IT service that makes it harder for som

The replacement of fossil fuels by renewable fuels such as biogas and biohydrogen will require efficient and economically competitive process technologies together with new kinds of biomass. A two-stage system for biogas production has several advantages over the widely used one-stage continuous stirred tank reactor (CSTR). However, it has not yet been widely implemented on a large scale. Biohydro

När Lissabonfördraget trädde i kraft den 1 december 2009 medförde det viktiga förändringar inom EU:s utrikespolitik. Målet var att öka EU:s samstämmighet i dess externa relationer i syfte att stärka EU:s roll som global aktör. Det nya fördraget inrättade en hög representant för den gemensamma utrikes-och säkerhetspolitiken (HR) samt en assisterande utrikestjänst (EEAS). De nya funktionerna är histThe entry into force of the Lisbon Treaty in December 2009 brought several important changes in the field of EU Foreign Policy. The goal was to enhance coherence in EU external relations to strengthen the role of the EU as a global actor.

The Swedish Stroke Register (Riksstroke) was founded in 1994. Riksstroke includes registration of acute stroke, with a follow up after 3 months and 1 year. The Stroke policy and quality register research group has several ongoing projects based on data from Riksstroke, and in many studies also using data record linkage to other national registers and data bases.

Recently, there has been an increase in apartments with a large number of inhabitants, i.e., high residential density. This is partly due to a housing shortage in general but also increased migration, particularly in suburbs of major cities. This paper specifies issues that might be caused by high residential density by investigating the technical parameters influenced in Swedish apartments that a

Popular Abstract in English What is common between the science of physics and global politics? They both define power in terms of energy. Indeed, the uneven distribution of petroleum reserves has been one of the main reasons of social, political and economic problems worldwide. Even more worrying is the rapid increase in the levels of greenhouse gases in the atmosphere. This is mainly caused by ouCaldicellulosiruptor saccharolyticus is an extremely thermophilic, strictly anaerobic, Gram-positive and cellulolytic microorganism with a natural ability to produce hydrogen (H2) at nearly theoretical maximum yield, i.e. 4 mol/ mol of glucose. Due to its CO2-free combustion and high energy density, among other desirable properties, H2is touted as a fuel of the future. Biological H2 production b

Alternative fuels for combustion engines are becoming increasingly popular as society is pushing to phase out fossil energy to reduce CO2 emissions. The compression ignition (CI) engine has a high overall efficiency which makes it a valuable option for the transport fleet, despite the well known NOx and soot pollutants it emits. These two pollutants are emitted due to a combination of high local cAlternative fuels for combustion engines are becoming increasingly popular as society is pushing to phase out fossil energy to reduce CO2 emissions.

After electrophoresis of an alkaline extract of type 15 group A streptococci, three main precipitation lines were obtained in diffusion experiments against commercial human polyclonal IgG (lines 1, 2 and 3). Nineteen of 23 sera (83%) from apparently healthy human individuals gave line 3, while 6 of them (26%) gave line 1. The sera giving line 1 did also give line 3. Line 2 was obtained with 2 sera

Popular Abstract in English Plants, algae and some bacteria are able to harvest solar energy to run chemical reactions by a complex process known as photosynthesis. Crucial molecules in this process are the so-called light-harvesting antennas. These antennas contain large amounts of pigments, such as chlorophyll, that are used for solar light absorption. Moreover, these pigments are also involved Multichromophoric systems are very important in photosynthesis and any device that uses solar energy for its operation. This is because multichromophoric light-harvesting antennas are responsible for the absorption of light and the efficient transfer of the absorbed energy toward distinct places where it is to be used or stored. Over the last 10 years polarization sensitive single molecule methods

The global pandemic has initially negatively influenced the financial markets all over the world. As a consequence, the volatility in the stock markets increased and investors have experienced great monetary losses. In addition, the volatility spillover has increased between different markets and assets, which additionally amplifies the negative influence by the pandemic. This motivates the search

Popular Abstract in English Energy savings and climate change mitigation have been discussed in the world since the oil crisis in the 1970s and the building sector has been seen as one of the largest contributors to global warming effects in the world. Energy efficiency in buildings is a critical issue to be addressed in order to reduce electricity energy used in buildings and is one of the main tMozambique, situated in south-east Africa, has sub-tropical and tropical climate and plenty of natural resources for energy production. The country is however poor, and only about 25% of the population has access to electricity from the grid. A very large part of the energy used in the country is used in the residential sector, and there is a general lack of knowledge, regulations and tools concer

This thesis presents the works on fabrication and measurements done with micro cantilevers and a micro channel system, fabricated in the photo-resist SU-8. SU-8 is a polymer patterned by UV lithography which offers a cheap and fast processing and is an interesting alternative to standard Si techniques. For the structures intended here, it proved to be a well suited material and promising results w
