Ekosystemtjänster är ett viktigt begrepp för att sprida förståelse om naturens värde för människan och det finns ett flertal kategorier av tjänster som naturen bidrar med. Vissa tjänster är mer aktuella än andra beroende på vilken miljö man fokuserar på, och i detta arbete ligger fokus på att utvärdera reglerande ekosystemtjänster i stadsmiljön då grönytor i dagens städer hotas allt mer och mer av
The language learning process by third age learners has recently become a field of interest for linguistic research. However, it has been studied mostly regarding psychological and cognitive considerations (stress, motivation, attention, memory, etc.), rather than according to language internal factors. The present study aims to provide a contribution by investigating the mastery of Italian gramma
A tool for studying human disease The human body is divided into small compartments called cells and each cell contains the information that is needed to develop a human being from the moment of fertilization to the full grown adult. The information is stored in the form of a twisted ladder consisting of building blocks called deoxy ribonucleic acids, or DNA. DNA is made up of four types of deo
Everyday products might make you blind! I think we all can appreciate at least one of the following products: sun screen, scratch free frying pans, self-cleaning paint, makeup, food packing and odorless clothes. These are all everyday products were you can find tiny objects, called nanoparticles. Nanoparticles are defined as objects were one dimension is between 1-100 nm, that is, 1-100 billionth
Protein-protein interaktioner i bakterier Att proteiner är i kontakt med varandra är nödvändigt i en cell för att den skall kunna fungera. Proteinteraktioner spelar en avgörande för bland annat genreglering och metabolism i en cell. Genom att upptäcka fler av dessa interaktioner, eller signalsystem, öppnas nya möjligheter upp inom den medicinska världen. I det experiment vi har utfört har vi för
OMG! Cancer Riddle Almost Solved, or what?! Cancer, which has been described as the disease of the 21st century and compared to the plaque, has for long been of greatest interest and confusion to researchers. Today, cancer is among the most common diseases worldwide. In 2012, 14 million new cases and 8.2 million deaths were reported. The various cancer types are in general classified from what ti
Urban jungel - Hur skapar vi parker rika på insektsliv? Vi har alla hört om hur pollinatörer har minskar världen över. Globalt har antalet bin minskat, bland annat på grund av intensivt jordbruk som skapat brist på föda och livsmiljöer. När jordbrukslandskapet blir en allt kargare miljö för våra pollinerande insekter – skulle städerna istället kunna innehålla miljöer där de kan leva, äta och fort
Technological advances in cloud technology, robotics, and telecommunications could provide for new and interesting applications. This thesis investigates how a combination of these areas can be utilized in order to improve performance in a smart manufacturing setting. In doing so, an architecture based on the Actor model has been used. The proposed architecture is both described from a theoretical
Röda blodkroppars roll i koaguleringen av blodet Blodet består till hälften blodkroppar (olika cell typer) och till hälften blodplasma, som är en vätska. Blodkropparna delas in i tre typer där röda blodkroppar transporterar syre, vita blodkroppar är en del av vårt immunförsvar och blodplättar är viktiga för att blodet ska koagulera. Koaguleringsprocessen är viktig för att stoppa blödningar vid sk
China’s rapid urbanization process has included a large scale migration of rural labor migrants to the cities since the 1990s. The education problem of their children who migrate together with them also becomes increasingly prominent. In order to allow migrant children enjoy a fair education, China introduced the "two oriented" policy in 2001. This policy clarifies that the management re
This MSc thesis covers the development of a Modelica model of an engine liquid cooling system for the trucks manufactured by MAN Truck & Bus AG. The mathematical assumptions used for transcribing existing models are described and the reasoning behind the modeling process is provided. The separate component models are validated with two sets of input signals. Primarily with a dynamic, transien
Skräp till middag? Visste du att tandkräm, cigaretter och plastpåsar hänger ihop med vad du äter till middag? Läs vidare så ska jag berätta hur. Lägger man ihop allt skräp som människor på Jorden skapar varje dag blir det väldigt, väldigt mycket. En ganska stor del av skräpet hamnar till slut i sjöar, floder och hav där det kan påverka de djur och växter som lever där. Men nu kanske du tänker, va
Examensarbete vittnar om bättre tider för njursjuka För få utförda kontroller av vattenkvalitet kan medföra livshotande tillstånd för njursjuka dialyspatienter. Ny teknik kan öka provtagningsfrekvensen och höja säkerheten. Den konstgjorda njuren Dialys är en behandling som syftar till att ersätta njurarnas funktion; att rena blodet från gifter och överflödig vätska. Vid hemodialys, även kallad bRenal diseases are an increasing problem worldwide and when kidney transplantation is not possible, dialysis treatment is the solution. An increasing number of patients choose to perform their dialysis treatment at home by implementing the dialysis machine and a water purification system in current electric and water supply, so called home hemodialysis. The quality of the water used for the prepar
How are microbial communities shaped by their climate? Significantly more carbon (C) is stored in the world’s soils than is present in the atmosphere. Although we hear a lot about increasing amount of carbon dioxide (CO2) in the atmosphere, mainly due to anthropogenic activity such as emissions from e.g. the car industry, we tend to forget about one of the crucial factors that can determine the
Look into my eyes Epilepsy is a serious neurological condition characterized by spontaneous recurring seizures. The word seizure comes from the Latin word sacire and means; to take possession of. This is a very horrible yet very accurate description of how a severe seizure could look like. Although treatment is available, it is ineffective in 30% of the patients and still just symptomatic. The n
The competition in the power plant business is today extremely hard and all manufacturers’ technics to achieve as low heat rate in sold power plants are very refined. This in combination with high fees for companies that can’t achieve what’s agreed in the contracts has made the feedback process very important in order to keep the business successful. A fossil power plant has therefore been evaluat
The objective of this thesis is to conduct an illustrative case study examining how child labour and the decision to legalize child labour from age ten might impact Bolivia’s future economic growth and development. By doing so, this thesis yields insight into the issue of child labour and its impact on economic growth and development as well as the effectiveness of child labour laws and regulation
En oro över snabbt stigande bostadspriser har öppnat upp debatten om reduktion av ränteavdraget i förhoppning att dämpa utvecklingen av de stigande bostadspriserna. Denna studie undersöker kostnaden att äga bostad, de ingående parametrarnas vikt med fokus på ränteavdragets påverkan. Undersökningen låter småhus representera den svenska bostadsmarknaden. Metoden som används är imputed rent, en ekvat
As the era of self-driving cars approaches, there is extensive discussion in the media about the next generation of vehicles: the potential safety benefits offered by new, increasingly automated, advanced driver assistance technologies, as well as the public’s possible distrust and reluctance to use them. This thesis contributes to the discussion by offering a cultural analysis of car safety. The
In the previous decades, mm-Wave frequency bands have largely been ignored for cellular communication because of the high free space attenuation as well as the cost and complexity of mm-Wave RF circuits. However, with the improvement of RF and antenna technologies over the last decade, it has become feasible to con- sider mm-Wave bands for cellular communications. With the large bandwidths availab
