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

Populärvetenskaplig sammanfattning: Under året 2001 kom forskare i hela världen överens om att globala klimatförändringar existerar och att människliga aktiviteter har påverkat dem, framförallt genom utsläpp av koldioxid (CO2). Kyoto Protokollet är en global överenskommelse som kräver en minskning av CO2 utsläpp (med 1990 som basår) och fem andra växthusgaser med 5% fram till 2012. Ett sätt som näIn 2001, the Intergovernmental Panel on Climate Change approved human impact (mainly through the emission of carbon dioxide (CO2)) on global warming. The Kyoto Protocol is a global contract that proposes the reduction of CO2 and five other greenhouse gases by 2012 to at least 5% below the level of 1990. One reduction strategy included in the Protocol is the Clean Development Mechanism (CDM). It su

Med den globala uppvärmningen förutspås klimatet i arktiska och subarktiska miljöer förändras påtagligt. Enligt IPCCs senaste rapport kan både temperatur och nederbörd öka dubbelt så mycket som det globala genomsnittet, och störst ökning väntas under vinterhalvåret. Många känsliga ekosystem och miljöer kommer med stor sannolikhet att påverkas redan vid små förändringar. Ett exempel på sådana miljöThe on-going global warming is projected to have large impacts on the arctic and subarctic environment. Especially vulnerable are ecosystems with narrow climatic envelopes and with small possibilities of adaptation. An example of this is the palsa mires, subarctic mire complexes with patches of permafrost. Palsas are peat mounds with a frozen core, formed by the expansion and upheaval of the segre

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

1. Theory predicts that the processes generating biodiversity after disturbance will change during succession. Comparisons of phylogenetic and functional (alpha and beta) diversity with taxonomic diversity can provide insights into the extent to which community assembly is driven by deterministic or stochastic processes, but comparative approaches have yet to be applied to successional systems. 2.

Purpose: To investigate the possible differences between SPECT/CT based whole-remnant and maximum-voxel dosimetry in patients receiving radio-iodine ablation treatment of differentiated thyroid cancer (DTC). Methods: Eighteen DTC patients were administered 1.11 GBq of 131I-NaI after near-total thyroidectomy and rhTSH stimulation. Two patients had two remnants, so in total dosimetry was performed f

BACKGROUND: Atrial myopathy refers to structural and functional cardiac abnormalities associated with atrial fibrillation and stroke, but appropriate diagnostic criteria are lacking.OBJECTIVES: This study aimed to assess prevalence, clinical correlates, and overlap between potential atrial myopathy markers.METHODS: The population-based SCAPIS (Swedish CArdioPulmonary bioImage Study) prospectively

Globins are usually associated with oxygen carriage in vertebrates. However, plants also contain similar heme-containing proteins, called phytoglobins (Pgbs). Unlike conventional hemoglobin, these proteins are often linked to nitric oxide metabolism, energy metabolism and redox maintenance under hypoxic and related abiotic and biotic stress conditions. Class I and II non-symbiotic Pgbs (nsPgbs) ha

Monitoring soil moisture at the Earth'surface is of great importance for drought early warnings. Spaceborne remote sensing is a keystone in monitoring at continental scale, as satellites can make observations of locations which are scarcely monitored by ground-based techniques. In recent years, several soil moisture products for continental scale monitoring became available from the main space age

Nitrous oxide (N2O) is one of the three primary anthropogenic greenhouse gases. The agricultural sector accounts for 75.7 % of all anthropogenic N2O emissions in Germany (Umweltbundesamt, 2012). Thus, accurately estimating N2O emissions as well as mitigation strategies for N2O are crucial. This study optimizes the process-based model DNDC to simulate N2O emissions by conventional winter wheat and

As 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

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

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

Populärvetenskaplig sammanfattning Vi lever idag i ett informationssamhälle och delar av denna information är geografisk. Denna geografiska information kan användas för att skapa kartor efter egna önskemål och för specifika användningsområden. Genom att ansluta till en webbsida som tillhandahåller visningstjänster av kartor kan en användare välja vilken information som ska vara med i en karta och We live in an information intensive society and geographic data are part of this information. These geographic data are used by private persons to plan holiday trips or to find the way to business meetings. Companies utilize geographic data in fields such as forestry, construction work, and tourism. Local municipalities require geographic data for planning purposes, and in the academic world much

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

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

Jordens havsnivå förändras ständigt och dessa förändringar kan ha olika orsaker: i ett längre geologiskt tidsperspektiv är det processer i jordens inre som påverkar havsnivån, men i ett kortare perspektiv spelar till exempel tillväxten och avsmältningen av inlandsisar stor roll. Under kvartärtiden har den sistnämnda processen varit den dominerande vad gäller att påverka havsnivåerna: vid istider hResults from an investigation of relative sea-level changes from c. 11,000 cal. yr BP to the present in the Tasiusaq area, Inner Bredefjord, southwest Greenland, are presented in this thesis. Isolation sequences from two small lakes have been identified using stratigraphic analyses, XRF-scanning, loss on ignition and macrofossil analyses. Macrofossil and bulk samples have been dated in order to e

It is a textbook knowledge that charges of the same polarity repel each other. For two monovalent ions in the gas phase at a close contact this repulsive interaction amounts to hundreds of kilojoules per mole. In aqueous solutions, however, this Coulomb repulsion is strongly attenuated by a factor equal to the dielectric constant of the medium. The residual repulsion, which now amounts only to uni
