Popular Abstract in Swedish Osteoporos (benskörhet) är en sjukdom som drabbar de äldre och leder till att skelettet urkalkas och därmed förlorar delar av sin styrka. Detta bidrager till olika typer av frakturer (brott av benet) där de vanligaste är handleds-, axel-, kot- och höftfrakturer. Andelen frakturer ökar i befolkningen, vilket både medför ökade kostnader för samhället och invaliditet för dThe aim of this thesis was to evaluate bone mass and bone size in girls and boys from age 12 to 16, with special attention to physical activity. We also wanted to retrospectively evaluate the effect of exercise for the years preceding age 12. The findings were as follows. Sixteen year old adolescents in a rural area had higher areal bone mineral density in the total body and the spine compared wit

Popular Abstract in Swedish Då reumatisk värk och artros är en växande folksjukdom har vi valt att studera proteiner som är involverade i dessa sjukdomar. Vi har arbetat med proteiner som finns i utrymmet utanför cellerna, dvs. den extracellulära matrisen. Cellerna formar sin egen närliggande miljö genom att utsöndra diverse proteiner. Dessa proteiner bildar sedan ett komplext nätverk med varandraThe cells of higher organisms exist in a complex protein network, the extracellular matrix (ECM), which has a wide variety of different components such as glycoproteins, proteoglycans and carbohydrates. As well as being the physical scaffold on which the cells are dependent for their positioning and mobility, the ECM exercises control over the cells, and changes in the matrix will affect the adhes

Aims: Climate change is known to drive both the reshuffling of whole assemblages and range shifts of individual species. Less is known about how local colonizations and extinctions of individual species contribute to changes at the community level. Our aim was to estimate the contribution of individual species to a change in community composition attributed to climate change and to relate these sp

When an agitator is in commission for an extended period of time the impellers can become clogged. In order to clean the impeller, the agitator is runned backwards. This is one of the main functions for a product that CG Drives & Automation is developing for a customer in the agitator business. The purpose of this bachelor thesis is to develop and test this product for CG Drives & Automati

With growing awareness about their environmental impact, music festivals have increased their efforts to become greener since the 2000s. In line with this trend, the German Fuchsbau Festival developed a transport plan, taking into account that up to 80.0% of a festival’s emissions are produced through audience travel. Aiming at triggering a greener travel behaviour among its visitors, four measure

Sjögräs förändrar kemin under sig – betydelse för havets skogar att ta upp koldioxid Sjögräsängars betydelse för såväl den lokala vattenkemin som den globala koldioxidbalansen är väl känd, och de kallas ofta för havets skogar på grund av deras höga produktivitet och förmåga att lagra kol från atmosfären. Vad som dock händer under botten, i porvattnet bland sjögräsets rötter och dess associerade mSeagrass systems are integral components of both local and global carbon cycles and contribute to substantial modifications of seawater biogeochemistry which has ecological ramifications. However, the influence of the roots and rhizomes of seagrasses on surrounding porewater biogeochemistry is not fully understood, and it remains to be determined what exact role this marine plant and the associate

This study charts the possibilities of recycled plastic and its use as an alternative building material for low-income housing in Colombia. The building materials in the study have been compared with respect to their physical properties, the cost and how they affect the indoor climate in each building. Colombia is a country that has been subjected to civil war for many years, which has contribute

Water management tackles complexities within the interconnected social, political, economic and ecological systems across scales, while aiming to meet the needs of multiple stakeholders dependent on water. Many tensions and unsolved issues persist in water management regarding socio-political power structures, spatial scale, and relations between stakeholders who have different perceptions on prob

It can no longer be refuted that greywater reuse is paramount to curbing the persistent global water crisis. Of the domestic wastewaters, greywater is less polluted than blackwater, but treatment is still necessary to make it safe for reuse. The most common greywater reuse application is toilet flushing. However, the use of vacuum toilets in the Oceanhamnen project, covered in this thesis, means t

During migration birds are exposed to several challenges, one of these are the potential threat of getting oxidative stressed. Oxidative stress can be defined as when free radicals are produced in a vastly amount so antioxidants cannot detoxify them. This is the case at higher metabolic rate such as migratory flight, and probably during hyperphagia at stop-over. The aim of this paper was to invest

Antibiotika är en av de viktigaste upptäckterna under 1900-talet. Med antibiotika blev det möjligt att bekämpa och förhindra bakteriella infektioner. Ett växande och svårlöst problem är antibiotikaresistans. Detta projekt syftar till att hitta alternativ till klassisk antibiotika. Vi har arbetat med sialinsyra, en kolhydrat som återfinns på cellytan. De flesta bakterier tillverkar inte själva siaThe development and the use of anibiotics since the second half of XX century really affected the approach on treatment and prevention of infectious diseases. Despite a lot of resources and energies has been invested on the research, antibiotics resistance is a growing phenomenon in the last years. Today this problem has become a real public health priority worldwide, not only for the important cl

Att dika skogar till förmån för bland annat bättre tillväxt kan påverka och förändra faktorer som marktemperatur och markfuktighet vilka är de viktigaste faktorerna för markrespirationen och flödet av koldioxid till atmosfären. Markrespirationen svarar för huvuddelen av koldioxidflödet till atmosfären från ett markbundet ekosystem. Koldioxid är en viktig växthusgas och små förändringar av flödet kDitching forests in favor of for example better tree growth can affect and change factors such as soil temperature and soil moisture. Those are the most important factors for soil respiration and the flow of carbon dioxide (CO2) into the atmosphere. The soil respiration accounts for the major flux of CO2 to the atmosphere from the terrestrial ecosystem. CO2 is an important greenhouse gas and small

Grönlands inlandsis utgör världens näst största färskvattensreservoar. Forskning har visat att Grönlands inlandsis förlorar mer och mer massa, vilket också bidrar till den stigande havsnivån, i kombination med andra faktorer. Avrinningen förväntas också öka i framtiden på grund av den globala uppvärmningen. Hur mycket massa som lämnar Grönlands inlandsis beror på den totala massbalansen. Den totalThe Greenland Ice sheet (GIS) is the second largest ice sheet on Earth and thus stores a large amount of Earths freshwater. Because of climate change and the Arctic amplification, GIS is experiencing changes and increased melt rates. The total mass budget determines the amount of sea level rise caused by input from freshwater from the GIS. Surface mass balance (SMB) plus the dynamic mass losses fr

Glacier advances in the Écrins massif (French Alps) during the Late Glacial and the Early Holocene are poorly constrained. Based on field observations, a high-resolution digital elevation model and an orthophoto, glacial landforms in the upper Drac Blanc catchment were mapped. Thanks to 42 new 10Be exposure ages, the timing of the stabilisation of selected moraines was constrained. The application

Today cities are the result of centuries of history and human development, accelerated during the past 100 years. Post-industrialization, modernism’s top-down city planning approach, and the prioritisation of motor vehicle design over humans resulted in more people moving to cities, more space needed to allocate new vehicles, expansion over rural areas, and exponential pollution growth. Thus, huma
