Methods: An integrative systematic review of literature was conducted. The literature was collected in CINAHL, Medline and EMBASE databases. Refined keyword search is further detaile

Chemical hazard assessment is a procedure in chemical regulation to set which concentrations of chemical substances that are safe to an ecological system, i.e. where a majority of the species in the systems is not negatively affected by the substance. The Species Sensitivity Distribution (SSD) is an assessment model to estimate hazardous concentration based on toxicity data from representative spe

Kurdistan region of Iraq (KR-I) has continually evolved in a region amidst turmoil. Currently, the region is exerting internal sovereignty and administers its own foreign-policy. Through the conduct of field-based interviews in KR-I, this study seeks to contribute to the understanding of the regions relationship with its parent state Iraq, from a perspective of foreign-policy decision-making, spec

Semiconductor Nanowires are promising building blocks for advanced optoelectronic devices since their small diameter give rise to quantization effects. The small diameter also makes them susceptible to non-radiative recombination due to surface states. A consequence of non-radiative surface recombination is a reduction of a total recombination lifetime. This is in turn limits an internal quantum e

Forskning visar att träning i att använda målspråket behövs för att befästa språkkunskaperna och att högre muntlig användning av målspråket av både lärare och elever i under- visningen leder till högre resultat. Samtidigt finns det utmaningar i att förmå eleverna att våga öva på just att tala målspråket. Med detta som utgångspunkt undersöktes vad som påverkar motivationen hos elever i årskurs 8 fö

Interagerar plast och hormon med varandra i vatten? Utsläpp av läkemedel bidrar till att ett av de vanligaste syntetiska hormonen Ethinylestradiol (EE2) hamnar i akvatiska miljöer. Årligen bildas enorma mängder plast, när plasten hamnar ute i miljön bryts ned den till små nanopartiklar med speciella egenskaper. Denna studie undersöker hur EE2 och nanopartiklar binder till varandra i vatten. Av allPlastic materials and synthetic hormones are found in aquatic environments globally. Plastic in water can degrade to nanoparticles (NP) with special characteristics, in the environment nanoparticles and hormones have a proven effect on wildlife. Synthetic hormones are widely used in contraceptives and medications and one of the most common synthetic hormones used is 17-alpha-ethinylestradiol (EE2)

In 2004, acute labour shortages were first observed in labour-intensive export-processing sectors in China’s coastal provinces. Paired with rising wages in rural and urban areas, many economists have claimed China has reached its Lewis Turning Point of economic development. This dissertation reviews these claims by context-testing Lewisian theory, and finds little evidence to suggest China has met

Vid marktekniska undersökningar i finkorniga jordar är det av stor vikt att korrekt kunna bestämma den odränerade skjuvhållfastheten. Detta görs idag vanligtvis ute i fält med en uppsjö av sonderingsmetoder som ger olika mått på hur fast jorden är. För homogena leror och sand finns det en stadig empirisk grund för hur dessa sonderingsparametrar räknas om till odränerad skjuvhållfasthet, men hur seThe undrained shear strength is a key parameter in the design process of geotechnical structures. One of the most frequently used methods to investigate this parameter is the cone penetration test (CPT). The CPT does not measure the undrained shear strength directly, but instead the resistance that a conic probe encounters as it is pushed into the ground. A calibration factor, the cone factor (Nkt

En traktor med skogsvagn är ett tämligen stort ekipage som i skogen sällan har gott om plats att ta sig fram på. För att göra det möjligt är många skogsvagnar utrustade med en extra led på dragstången, så kallad vagnstyrning. Denna led används för att förskjuta vagnen i sidled och därmed anpassa dess färdväg. Detta är mycket användbart i skogen då det medför att, med rätt inställning, vagnen följeA tractor with a forest trailer is a large vehicle combination. When it is driven in the woods there is not a lot of space. To make it possible to turn in limited spaces forest trailers are equipped with an extra joint on the drawbar. This is called drawbar steering. This joint changes the geometry of the trailer in order to make it take another path. This feature is very convenient in the forest

En växande världsbefolkning, politiska regleringar och en strävan att öka andelen energi från förnyelsebara källor har resulterat i att intresset för vindkraftsverk ökat. Winfoor AB utvecklar `Triblade’, en ny teknologi för vindkraftsverksblad som ämnar öka effekten samtidigt som bladen kan göras lättare, billigare och enklare att transportera än dagens vindkrafsverksblad.A globally growing population, an increased energy consumption and growing environmental awareness have made the interest for renewable energy sources, such as wind power, higher. As a result of the increased demand the need for new and improved technologies have increased. The energy production of a wind turbine is highly affected by the rotor blade length, which is limited by the massive dead lo

This paper analyses the impact of inflation targeting as a monetary policy framework on inflation volatility and inflation rates in Uganda, with a comparison with South Africa and Ghana (full-fledged inflation targeting economies) and Kenya that opted for a forward looking monetary framework. The results show that inflation targeting in Uganda has been efficient in reducing inflation volatility an

Today’s network outdoor surveillance cameras face problems when water drops stick to the protective glass in front of the camera lens, thus significantly disturbing the image. This problem mainly occurs during heavy rain weather or when the camera is being cleaned with a hose. Solving this problem would greatly improve the performance and versatility of outdoor surveillance cameras. The way this p

The incineration furnace at National Veterinary Institute (SVA) in Uppsala, Sweden, runs approximately 2,150 hours a year and generates a large amount of waste heat. Some of this heat is partially recovered, and is used for heating one of the main buildings during the furnace operation. However, around 2,000 MWh is wasted annually due to unavailability of any storage system. This wasted heat is ap

Stora delar av bostadsbeståndet i Sverige är uppfört efter modernistiska planeringsideal med uppluckrade gränser mellan det privata och publika. I dessa miljöer är alla ytor inte direkt avläsbara ifråga om ägarförhållanden och användning. I många fall är det inget problem, det kanske finns tillräckligt med ytor för alla,underförstådda överenskommelser regleraranvändning effektivt, men i andra fallA great part of the Swedish housing stock is built according to modernistic planning ideals where boundaries between public and private propertiesare not always visible, neither in ownership nor in use aspects. In many cases this is not a problem, there is plenty of space for everyone and implicit agreements regulate use, but in other cases areaswon’t be used, conflicts occur or fences will close

This thesis aims to create a simple evaluation tool suited for assessment of value creation in Circular Business Models (CBMs). Transitioning from a linear business model to adapting the Circular Economy principles, brings in a range of new challenges, for both a company and its consumers. However, it is also important to note the different opportunities of value creation that arise due to such a

The notional amounts outstanding of over-the-counter (OTC) derivatives had grown exponentially for almost two decades and its rapid growth were mainly due the increase in OTC interest rate derivatives. As of december 2014, the total notional amounts outstanding in the global OTC market was 630 trillions USD and the OTC interest rate derivatives represents about 80% of the market. Trading with OTC

Partikelfysik är den del av fysiken som beskriver de allra minsta beståndsdelarna i vår värld. De ekvationer som används för att beskriva dessa små partiklar kan vara mycket svåra att lösa, det finns faktiskt ett pris på en miljon dollar till den som lyckas lösa ett visst problem inom partikelfysik. För att underlätta alla beräkningar som ska utföras, så har fysiker tagit fram några regler som manSolitons are solutions to classical field equations that are particle like, meaning they are localized in space, have definite energy and can be stable against deformations into the vacuum. In this thesis we investigate under which circumstances such solutions may exist and what effects their existence could have. It will turn out that topological considerations will play a large role in the quest
