Påverkar en kall eller mild vinter Sveriges population sammansättning av vinterfåglar? Somrar är ofta en härlig tid med sol, grönska och ett rikt djurliv, inte minst med alla vackra fåglar man kan se. När den kalla och ruggiga vintern kommer migrerar de flesta fåglarna men en del fåglar som klarar vintern blir kvar. Med den pågående klimatförändringen, i form av ökande temperaturer, som leder til
This project proposes a design of dwelling for visitors and locals, who wants to enjoy one of earths beautiful phenomena, in this case the northern lights. The dwelling is located near the lake Mývatn. The framework is based on the theory of nding the common denominator between the natural elements and tectonics of architecture, by focusing on how we experience architecture in the relation and dia
Since Abe Shinzo returned as Prime Minister of Japan, the question about just where his ambitions will lead Japan have become much more frequent. Through a range of bills and measurements, he has sparked a debate as to whether Japan has seen radical change, or whether it is merely incremental in nature. This thesis contributes by adding a nuanced approach to ‘measuring’ change in Japan’s security
Denna magisteruppsats baseras på en översättning av ett utdrag ur den amerikanske professorn och litteraturkritikern Edward Margolies bok New York and the literary imagination: the city in twentieth century fiction and drama. Uppsatsen inleds med en källtextanalys som utgår från Lennart Hellspong och Per Ledins metod i Vägar genom texten: Handbok i brukstextanalys (1997). Därefter följer ett kapit
Bumblebee ocelli, the new buzz Bumblebees have been described as the insect worlds pandas, cute balls of fur with a calm personality and charm. All this is just a bonus when they also provide an ecosystem service by pollinating the worlds flowers and plants. Being so recognizable has led to that bumblebees have been studied more than many other species, but there are always more things to discov
Lever stadsfåglar också stressiga stadsliv? Det är många av oss som tycker stadsliv är stressigt; mycket folk i rörelse, det är bilar och ljud överallt, listan kan göras lång. Det är inte bara vi människor som utsätts för alla dessa intryck, utan även alla de djur som lever i eller nära en urban miljö. Fåglar är en grupp där flera arter lyckats anpassa sig väl till stadsmiljöer, men trots detta s
Save the world with Trichoderma Today a lot of people are talking about the health benefits of consuming probiotics and the importance of having a good gut biome, but did you know that this is also be true for plants? A lot of people may have heard about the beneficial effect of mycorrhizal fungi and nitrogen fixing bacteria, but few have heard about Trichoderma. The fungus Trichoderma is a her
Finns det ännu plats för kronhjort i människans sköna nya värld? Dygnet är ännu ungt, den tidiga fågeln ännu knappast vaken och dess mask ännu trygg. Så sakteliga gör solen sitt inträde, daggen glittrar tacksamt när mörkrets ok lyftes av. Någonstans i fjärran hörs ett väldigt läte, Skånes konung hälsar omgivningen till lystring. Detta försök till en sorts Vilhelm Ekelund anspelar på Skånes landsThe red deer is an animal that most of us know and expect when speaking of big animals in the Swedish fauna. But this has not always been the case. The red deer was almost extinct in the beginning of the 20th century, the life force is mostly regained today but there are still hurdles in the way. The increase in population of the red deer mean an economic conflict with land owners because of its
This study explores the roles of genetic variation and phenotypic plasticity for explaining patterns of local wing colour variation in the common blue butterfly, Polyommatus icarus. Polyommatus icarus is one of the most widespread species of butterflies in Europe. Across its range, the female varies a lot in its dorsal colour, from all brown to almost totally blue. It has been suggested that, in S
Fåglar och ljus Fåglar är kända för sin goda syn och forskningen har nästan bara handlat om deras färgseende. Hur svagt ljus fåglar kan se är ett nästan förbisett område. Hitintills är det bara känt hos tre fåglar hur svagt ljus de kan se. År 1956 undersöktes tamduvans (Columba livia domestica) ljunskänslighet och 1977 var det kattugglans (Strix aluco) tur. Efter det dröjde det ända till 2016 då
The focal quest of this research is to find whether the repression of trade unions is the proximate cause of inability to improve conditions of work in RMG sector of Bangladesh. This research goes deep with several corresponding quests on inquiring about the international obligation of Bangladesh to protect trade union, the scope of international legal system that offered its advice, trade union’s
Electrification of energy demand is seen as one of the key elements of energy transition toward decarbonisation. E-mobility is one main side of the electrification process, and it is considered as a crucial way to reduce the emissions of the transport sector. A core element for a widespread adoption of electric vehicles (EVs) is the deployment of the charging infrastructure, and installing a micro
Niche theory predicts that cooccurring species must differ in their use of environments in order to coexist, thereby diversity can be maintained in a community. However, ecologically similar species do frequently occur in nature, hence species inhabit similar physical environs and share single underling resources. In coexisting species with a similar niche, ecological drift is thought to eventuall
Genetic variation in an immune defense gene The immune system is one of the barriers to the external world, and the multiple types of microbes that could be dangerous to our health. In the part of our immune system that we normally call the innate immune system, we have different sensors for these various types of microbes. The sensors are found inside some of the cells of mammals or on the surfa
During the Age of Mass Migration, 30 million Europeans left their home countries and emigrated to the United States. Sweden had one of the highest out-migration rates of the era. Between 1860 to 1920, around 1.3 million people–a quarter of the population–left Sweden to seek opportunity in the United States. This essay delves into one particular aspect of this historic migration episode. I study t
Measuring signals with high frequency common mode components are typically prone to measurement errors due to low common mode rejection at high frequencies. The purpose of this master thesis is to design a measurement probe that presents sufficient common mode rejection to measure current on high voltage motor drives directly at the switching stage, before filtering. Outlined in this work is the
Metod: Denna studie har utgått från en kvalitativ metod. Det har använts två metoder eftersom det bidragit till att studien skapat en mer korrekt bild av området som undersökts. De metoder som använts är kvalitativa intervjuer och iakttagelser. Teorier: Olika teoretiska ansatser har diskuteras i koppling till begreppet förtroende. Teorierna har delats upp i fysiska marknadsföringskanaler och digi
The collaborative economy represents a paradigm shift that could help to address the economic, social and environmental problems of our time. However, its ability to actually deliver that promise is highly disputed. This thesis aims to address the knowledge gap of the types of value that organisations based on collaborative consumption and production actually create, and the strategies that they u
Wine production has been demonstrated to negatively impact on the environment in a number of ways, threatening the well being of ecosystems and a sustainable future of the industry. With a general need for reducing environmental impacts; optimization of water resources has been identified the most critical environmental aspect in relation to wine production. Yet, several studies point towards inef
Today, many cities around the world are looking for means to reduce their consumption-originated emissions and in this way improve their sustainability. Consequently, local governments are becoming increasingly interested in the potential of the ‘sharing economy’ (SE). By enabling the consumption of resources and services through sharing as opposed to purchasing goods for ownership, urban sharing
