Plastic 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)
Titel: Socialt ansvar - eget ansvar eller styrmedel - Medarbetarskap eller kulturstyrning Universitet: Lunds Universitet, Campus Helsingborg, Institutionen för Service Management Syfte och frågeställningar: Syftet med vår uppsats är att undersöka och analysera hur ledningen i en organisation styr medarbetarnas eget ansvar utifrån organisationens sociala ansvarstagande med inriktning på ISO 26000.
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
The 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
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 fall
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
Solitons 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
Small biological airborne particles (aerosols) reside in the atmosphere and can influence human health, the climate and the environment. Whereas aerosol sampling technology is well-known, there is currently no satisfactory high-volume flow impinger for health and atmospheric monitoring applications. The aim of this thesis was to design and construct a working prototype of an impinger, a sampling d
Today, it seems as if every second designed object is referred to as timeless design. We use the word timeless as a selling word without really thinking about what it means. Through investigating the concept of timeless design, I found the physical paper book being probably one of our most timeless objects. There are tons of book storing furnitures on the market of which the majority consists of
Foreign direct investments (FDI) have in later years become regarded as a key engine to economic growth, which many developing countries find appealing. Developing countries do however often find it hard to attract FDI since they have an unstable political environment due to inferior levels of democracy. To overcome this issue, they turn to bilateral investment treaties (BITs) with the hope that t
The aim of this Master’s thesis is to research the presence of lesbians in historical archives. My material consists of interviews with four swedish archivists. The aim of these interviews is to research the priorities and the work that is beeing done at the archives concerning collecting material that is missing in the archive and making existing material related to lesbian lives accessible.
