Through biosilicification, organisms incorporate dissolved silica (dSi) and deposit it as biogenic silica (bSi), driving the silicon (Si) cycle in aquatic systems. While Si accumulation in marine picocyanobacteria has been recently observed, its mechanisms and ecological implications remain unclear. This study investigates biosilicification in marine and brackish picocyanobacteria of the Synechoco
In 2015, Denmark saw a historic number of refugees and asylum seekers, many of whom were of Middle Eastern heritage, reach its borders,. As a response to this, the Danish government began tightening its immigration and integration policies, and restricting entry to the country. Many of these restrictions have been criticized both domestically and internationally. This thesis analyses four Danish i
This thesis explores how subjects are constructed within the labour market program called Trelleborgsmodellen, or the Trelleborg Model. It focuses on the Labour Market Department within Trelleborg Municipality and how economic welfare applicants and street level bureaucrats are constructed in the policy. The analysis is based on policy document and interviews with labour market secretaries at the
Payments for watershed services (PWS) are intended to provide incentives to land users to adopt sustainable land management practices. They are also increasingly viewed as having positive impacts on the livelihood of local communities around protected areas. The St. Paul River, located in the St. Paul River basin, is the main source of potable water and hydroelectricity to Monrovia, a city with ab
The superconductivity under doping in the famous cuprate compounds is believed to originate in the CuO2 planes. The mediator of pairing is generally accepted to be induced from electronic degrees of freedom. While many mechanisms, such as spin fluctuations, have been proposed throughout the years, little research has been carried out on the role of the retarded attraction due to electronic overscr
As the most diverse group of animals in the world with more than a million describes species, insects varies in many aspects of their ecology. Bees are insects that can be found in many different habitats across the world. Some live in open landscapes while others live in denser vegetation, some are active in the night while others are active during the day. Since bees use their vision to navigate
The Covid-19 pandemic is one of the deadliest in modern history. Vaccines are currently the primary resource used for stopping the pandemic and minimizing harm. Yet despite scientific literature demonstrating the inefficiency of inequitable vaccine distribution, richer countries have historically and are currently procuring disproportionate amounts of vaccines; causing higher mortality rates, decr
There are many policy areas where the different governmental bodies need to work together to provide a service. Healthcare for elders in Sweden is one example where the region and municipality need to coordinate. The collaboration of eldercare has been criticised over the years for not living up to the set standards. The responsible authority for eldercare has changed a number of times since its i
This study takes a critical feminist anti-militarist perspective on the function and purpose of the support that families of soldiers are provided by militaries during deployment. The context in focus is Swedish deployment support of extended families of soldiers, the material selected is from the website and the forum of the voluntary peer and mentor based support organization Invidzonen.

Industriavloppsreningen på pappers- och dissolvingmassabruket Södra Cell Mörrum (SCM) har nyligen uppgraderats med ny utrustning för att minska utsläppen till vatten, och därmed möta rådande och framtida utsläppsvillkor samt krav på tillämpning av BAT (bästa tillgängliga teknik). Tillbyggnaden av reningsverket innefattar bland annat ett polymerflockningssteg, tre nya skivfilter, ett system för autThe industrial wastewater treatment at the Södra Cell Mörrum (SCM) paper and dissolving pulp mill was recently upgraded with new equipment to reduce emissions to water, aiming to meet current and future effluent requirements and comply with BAT (Best Available Techniques). The new extension of the water treatment facility mainly consists of a polymer flocculation step, three rotating disc filters,
Increased attention is nowadays devoted to waste management. The objective of this work is to analyse how commonly known business economic models and methods, as well as the Polluter-Pays Principle, can be applied to waste management in general and to waste fractionation in particular, so as to facilitate environmental optimisation of industrial and construction waste fractionation. In discussing
A range of observations points towards earlier onset of spring in northern high latitudes. However, despite the profound effects this may have on vegetation-atmosphere exchange of carbon (NEE), vegetation-atmosphere physical coupling, or the location of the tundra-taiga interface, the number of studies that investigate winter-spring transition fluxes in contrasting northern vegetation types is lim
Calcitonin gene-related peptide (CGRP) and related peptides may be involved in migraine pathogenesis. To understand their vasomotor role in the cerebral circulation, we performed two studies, a pressurized arteriography study of the middle cerebral artery (MCA) and a genuine closed cranial window (gCCW) in vivo study. Using the pressurized arteriography model rat MCAs were mounted on micropipettes
Information on soil mineralogy is essential for weathering rate calculations. Quantitative mineralogical analyses are expensive and time-consuming, and thus indirect methods of determining the mineralogical composition are important, for example estimating the composition based on the elemental content in till (total concentrations), or based on information about the underlying bedrock. The minera
The bone mineral content (BMC) was determined by dual photon X-ray absorptiometry prior to hip replacement in 22 patients with rheumatoid arthritis and 31 with arthrosis. Compared with the arthrosis patients, the rheumatoids had approximately 20 percent lower bone mineral content in the proximal femur, the lumbar spine, and in the innominate bone superior to the acetabulum.
