This study analyses the performance of the satellite derived Plant Phenology Index (PPI) against the Normalized Difference Vegetation Index (NDVI) for estimating start of season (SOS) and end of season (EOS) of vegetation growth in part of the Balkan Peninsula, Southeastern Europe (2000 – 2016). Results revealed that PPI and NDVI differ considerably; SOS and EOS may diverge by more than one month

Oslo has until now been divided into the west and east, separated by categories of economic and social class as well as a physical barrier, the river, Akerselva. The west predominantly represents people of middle to upper class, whereas the east represents the middle to lower class people. This division has been formed throughout history, as the river that separates Oslo has been home to industry,

The Yaw Power Backup System (YPBS) is a safety system that needs to be incorporated in the Wind Power Plant (WPP) in order to provide emergency power during a power outage. The YPBS enables the Wind Turbine Generator (WTG) to perform a yawing operation in extreme weather conditions. The yawing operation ensures the rotor is aligned with incoming wind, minimizing the acting forces on the blades and

The objectives of this thesis are to find a common ground for business and environmental interests and to evaluate the potential of Environmental Management Systems (EMSs) as transition tools to lead towards a greener economic paradigm. For these purposes it was assessed, which implications EMSs have for the competitiveness of small and medium sized enterprises (SMEs) within the first three years

Sex chromosome evolution is a fascinating research topic because sex chromosomes provide a snapshot of evolution in many different lineages. Sex chromosomes often cease to recombine and therefore degenerate, and have also often been reshuffled during their evolution from autosomes. It has been discovered that within Sylvioidea passerine species half of chromosome 4a has translocated and fused with

Issue of study: The plastic injection moulding industry has become highly competitive in terms of lead times and pricing, following an increase in low-cost manufacturing from Asia, as a part of the full supply chain. To remain competitive, mould tool manufacturers are looking to complement new tool manufacturing with local after-sales services in countries where their mould tools are being used. U

Med ökad andel intermittent elproduktion i Sveriges elproduktionsmix och ett åldrande stamnät ökar behovet av flexibilitet i elsystemet. Lagring av energi, till exempel i vätgas, är ett exempel på en sådan flexibilitetslösning, eftersom energin kan flyttas från tidpunkter med överskott till tidpunkter med högt energibehov. Syftet med examensarbetet är att undersöka energisystemnyttan med ett v ägaSweden’s increasing share of intermittent electricity production and aging backbone network has given rise to a need for flexibility in the energy system. A potential solution to this challenge is energy storage, where hydrogen is a possible pathway. This master’s thesis aims to investigate the energy system benefits of a hydrogen system for seasonal energy storage of excess solar electricity in a

A section of the Swedish library act stipulates that libraries are to pay specific attention to people with disability. Exhaustion syndrome is a mental disability that in recent years has started to grow rapidly in numbers. This master thesis is mainly aiming to study whether public libraries are welcoming and functional places for people with exhaustion syndrome but it also has a wider scope stud

Teknologins snabba utveckling och de omfattande förändringar som det inneburit för människans levnadssätt är både fascinerande och skrämmande. Allt eftersom tekniken utvecklats har vi kommit att bli mer beroende av elektroniska hjälpmedel, vilket ställt det moderna samhället inför utmaningen att finna nya energikällor och långsiktigt hållbara strategier att utvinna dem på. De senaste decennierna hAs the consumption of energy increase in today’s world, the need for new fuel sources is of central importance. In order to be considered viable in the long run, the new energy sources must provide high efficiency and low environmental impact. The search for alternative fuels and energy extraction methods have become increasingly focused on finding ways to mimic systems found within nature. Oxidor

Denna uppsats undersöker NJA 2023 s. 393 (”Vapenattrappen”), och dess konsekvenser för såväl gällande rätt som domstolarnas rättstillämpning. Domen kom under våren 2023 att kritiseras hårt. I målet stod två män åtalade för försök till vapenbrott, eftersom de påstods ha försökt inneha vapen. Vapnen byttes emellertid ut mot en ofarlig attrapp av polis ca. fyra månader innan de tilltalade dök upp, vaThis paper examines NJA 2023 s. 393 ("The Dummy Weapon"), and its consequences for both current law and practical legal application. The verdict would come to be heavily criticized during the spring of 2023. Two men were prosecuted in the case. They were charged with attempted exceptionally aggravated weapons offence, since they had allegedly tried to possess firearms. The firearms had,

Remote sensed vegetation biophysical indicators are derived from various sensors and methods and contribute to the quantification of vegetation growth. They are used as inputs to early warning systems for crop yield estimation, thus improving crop management and food security. However, the performance of any such system is affected by the performance of the chosen remote sensed biophysical indicat

Understanding the mechanisms of complex polygenic diseases like type 2 diabetes (T2D) is as complex as their nature. Cellular processes involved in glucose homeostasis need high and reliable energy supply. Mitochondria are the major energy producers in mammalian cells. Since majority of the mitochondrial genes are encoded by the nuclear genome, a tightly regulated and coordinated nuclear-mitochond

This dissertation examines how young people with Kurdish backgrounds form their identity in Sweden with regards to processes of inclusion and exclusion. It also sheds light on the ways these young people deal with ethnic discrimination and racism. Further, the study outlines the importance of these social processes for the discipline of social work and the ways social workers can work with disadva

We have measured the uptake capacity of nitrogen (N) and potassium (K) from different soil depths by injecting N-15 and caesium (Cs; as an analogue to K) at 5 and 50 cm soil depth and analysing the recovery of these markers in foliage and buds. The study was performed in monocultures of 40-year-old pedunculate oak (Quercus robur), European beech (Fagus sylvatica) and Norway spruce (Picea abies (L.

En vegetationskarta och en digital höjdmodell har gjorts över ett 54 km2 stort område beläget på Svalbards västkust, vid Isfjorden. Vegetationskartan är baserad på flygbilder och en undersökning gjord i fält under juli månad 1994. Systemet som användes vid klassificeringen av de olika vegetationstyperna är utarbetad av Elven et al. (1990) för en liknande studie i Gipsdalen på Svalbard. Vår vegetatA vegetation map and a Digital Elevation Model has been generated over a 54 km2 area situated at the western coast of Svalbard, at the Isfjorden fiord. The map is based on aerial photographs and a field survey made during the summer of 1994. The classification system used is described by Elven et alia (1990), for a similar study in Gipsdalen in the inner part of Isfjorden. The classification of th

Globalization has since the 90s played a big part in the way companies look at their business and strategic developments. Acting on a global scale introduces a new complexity when it comes to running a business successfully. Alfa Laval being a global player within their product segments, experiences this complexity with production facilities as well as employees spread around the globe combined wi

Tetra Pak is continuously working to increase the efficiency of the whole organisation. There is currently a general demand to improve by 20%. The number is not to be taken literately since efficiency is not defined nor is it specified how it should be measured. At Tetra Top the interpretation is that it is important to focus on efficiency and that it is up to individuals how and when it can be at
