Bokhögstubbar i Klåveröds strövområde : utbredning, egenskaper och betydelse för rödlistade vedlevande skalbaggar

Lack of dead wood is the main cause of decaying or loss of populations for many forest species. To increase the amount of dead wood is a prerequisite to maintain biodiversity in forests of northern Europe. In summer 2006 the recreation area Klåveröd, at Söderåsen in Skåne, Sweden, has been inventoried for high stumps (snags) of beech, (Fagus sylvatica). The result of the inventory has been compared with data of the real estate and forest management directories from the owner, region Skåne. The results have also been matched with the results from an inventory of saproxylic beetles in 2005, performed with windowtraps on selected snags both in the area and the adjacent national park Söderåsen. 594 snags were found on 747 ha.

Deaktivering av metanisering katalysatorer

A titania-supported nickel catalyst was prepared and tested in methanation in order to evaluate its catalytic properties (activity, selectivity and specially, activity loss), and compare it with an alumina-supported nickel catalyst.The titania-supported catalyst did not only show higher stability than alumina, but also presented a different cause of deactivation, carbon formation. In addition, a kinetic model was obtained for the titania-supported catalyst, and a study of the effect of different operating conditions (temperature, composition and partial pressures of synthesis gas and water) on the deactivation rate and carbon formation of this catalyst was performed.

Lek hos Stinkpadda (Bufo callamita): jämförelse av restaurerade och ickerestaurerade hällkar

The natterjack toad (Bufo calamita) is one of three species of toads living in Sweden. During the last decades declines in population numbers have been detected and are thought to be primarily due to loss of habitat, overgrown breeding ponds and competition from common toad (Bufo bufo) and common frog (Rana temporaria). In 2012 20 ponds in the location of Glommeskallen in Smögen were restored by clearing the ponds from overgrowth. The aim of this study was to investigate if natterjack toads used the restored ponds and if the restoration had made an impact on the natterjack population on the location. Presence of common toad and common frog was recorded, as was the presence of eggs and larvae of any of the three species.

Databas för forskningsdata, VTI

På VTI, så som på många andra forskningsorganisationer samlas data in, bearbetas och reduceras till slutsatser som slutligen publiceras. Data sparas idag ofta på den enskilde forskarens dator och stannar där. En hantering som genom att att maskinvara skrotas, riskerar att data, på sikt försvinner.Ett alternativ är att samla data centralt och strukturerat. Det ger inte bara möjlighet att skydda data från tidens tand utan öppnar även för att fler enkelt ska kunna använda data från en studie i andra studier. Detta kan göras både genom både jämförande studier och metastudier, där andra aspekter än de ursprungligen menade utvärderas.

Generering av analoga signaler från XSV-300

Att ett grafikkort ska behandla data och sen generera en bild på en skärm är en ganska logisk funktion för ett grafikkort. Vad som har gjorts här är att alla grundläggande funktioner för grafikkortet har tagits bort, detta för att ingen behandling ska göras. Detta har gjorts för att kunna låta data passera genom kortet med så hög hastighet som möjligt. Att låta data gå genom kortet var det första steget. Efter det skulle förhoppningsvis ett stabilt system ha uppnåtts där vi kunde göra överföringen av data snabbare.

Förändringar i markanvändning över tid och dess påverkan på vattenkvalitet

The EU Water Framework Directive has led that management follows the boundaries of natural catchments.The Swedish waters suffer from a nutrient overload that originates mainly from diffuse sources such as agriculture and the subcatchment of Hackstabäcken in Vallentuna Kommun, just north of Stockholm, has been chosen for this study because of its high nutrient load and because it has undergone obvious changes in land use through the years.In this study, the land use in 1902 is compared with the land use in 2011 in order to investigate if it has influenced the ability of the landscape to produce ecosystem services related to nutrient removal. These services will continue to be produced as long as the system is stable and resilient, but when landuse changes and manure from horses increases it will lead to disturbances that can convert a system from one regime in to a completely different one. That will result in loss, or degradation, of ecosystem services such as denitrification, phosphor sedimentation and adsorption, vegetation uptake and infiltration.The results of this study are based upon area calculations of landuse from old maps from 1902 and 2011. Through these maps it becomes clear that the forests in Hackstabäcken, has increased with 170 ha together with an urbanization of 311 ha, at the same time as wetlands and arable land has diminished and lakes has suffered from reductions. Wetlands have been reduced with 76 ha and the ones remaining are of insufficient quality from a nutrient removal perspective.Data from 1902 and 2011 regarding number of horses and bovines indicated a decrease in bovines and an increase in horses.

Säsongspåverkan i trädgårdsföretag : följder som kan leda till kompetensförlust inom näringen

The purpose of this final thesis is to investigate the effects of seasonal changes in the horticulture industry. In this study this includes mainly garden designers, constructors of gardens and parks and horticultural businesses at Österlen. Today the most important issue,both in private and in public environment, is that the winter occupation in this area is not big enough. The consequence of this issue can result in the loss of competence to other industries if educated personnel has to stay employed only over season. The study is trying to identify and rank factors that are contributing to the problem, and propose solutions that means work opportunities for companies in the horticulture industry as well as for their employees, during twelve months of the year..

Effekter av en idrottspsykologisk utbildningsintervention för friidrottstränare : med fokus på tränares förhållningssätt och ungdomars motivation och upplevelse av tävlingsnervositet

Abstract Aim: Since there is a lack of research based educational interventions concerning the relationship between coaches and young athletes, the aim of this study was to implement and examine the effects of sport psychology intervention for coaches in a track and field club. The research questions were: What are the effects of an educational intervention for coaches, with focus on a motivational climate, on: A) the coaches´ coaching approach B) their athletes´ goal orientation and C) their athletes´ perceived competitive anxiety?Method: The coach education stretched over two months and consisted of four two-hour lessons with focus on motivational climate, goal orientation and sport anxiety. Six coaches (three females, three males), aged 38-52 (M=44.33 years, SD=4.84) and their 59 athletes (27 males and 32 females) aged 12-14 (M=13.10 years, SD=0.82), participated in the study. A control group of 35 athletes (10 males and 25 females), of the same age (M=13.46 years, SD=0.70) and with similar demographic data, was also recruited.

Konsulters beskrivning av Big Data och dess koppling till Business Intelligence

De allra flesta av oss kommer ständigt i kontakt med olika dataflöden vilket har blivit en helt naturlig del av vårt nutida informationssamhälle. Dagens företag agerar i en ständigt föränderlig omvärld, och hantering av data och information har blivit en allt viktigare konkurrensfaktor. Detta i takt med att den totala datamängden i den digitala världen har ökat kraftigt de senaste åren. En benämning för gigantiska datamängder är Big Data, som har blivit ett populärt begrepp inom IT-branschen. Big Data kommer med helt nya analysmöjligheter, men det har visat sig att många företag är oroliga för hur de ska hantera och ta tillvara på de växande datamängderna.

Is big that big? -En studie om hur banker använder bid data i sin kundhantering

Bakgrund och problemdiskussion: I takt med att vår omgivning blir mer digitaliserad skapasvarje dag, timme och sekund allt mer data. De stora datamängder som skapas går underbenämningen ?big data? och kan förklaras som stora datamängder som överskrider kapacitetenför vad ett vanligt databassystem kan hantera. Genom big data kan företag få ökad informationoch kunskap om sina kunder och därmed få ett bättre underlag till sina Customer Intelligencelösningar.Big data är på många sätt lovande men det kvarstår en del utmaningar, bådeaffärsmässiga och tekniska innan det kan anammas fullt ut. Arbete och hantering av data tar idagupp cirka 7-10 % av bankers rörelseresultat och frågan är hur de skulle kunna utvinna och lagradenna data på ett effektivt sätt.

Autenticitet i ett öppna data-sammanhang : Utmaningar och möjligheter ur ett arkivvetenskapligt perspektiv

By tradition, archival sciences has emerged in a context with defined information processes, with explicit information producers and custodians to which consumers make requests for the information. In this process, the archival science has developed methods and strategies to preserve authentic and reliable records and by that providing trustworthy information. In an online society, people are using the internet to get information for different purposes. Even though there is no legal obligation to guarantee the authenticity, it is of societal importance that the end users get trustworthy information. In this online context, open data is a trend that is growing fast over the world and it is interesting because its conditions raises many questions regarding authenticity.Since open data is free to reuse, link and combine with other information, and it is preferably in primary format it raises questions about how to maintain the integrity and identity of the information, which is the constituents of authenticity as it is used in this work.

Uppdatering av metadata i ett Data Warehouse: ett organisatoriskt perspektiv

Data Warehouse är ett relativt nytt fenomen i jämförelse med traditionella databassystem, och i och med de senaste årens kraftiga tekniska utveckling har förutsättningar för att realisera konceptet skapats. Inom branschen finns ett antal problem rörande metadata, som i denna uppsats legat till grund för vår inriktning. Många av dessa problem beskrivs utifrån ett tekniskt perspektiv, vilket detta arbete inte gör. Vi har istället valt att undersöka vilka problem som föreligger vid säkerställning av att metadata hålls uppdaterat i ett Data Warehouse med hjälp av tydlig ansvarsfördelning. Vi har funnit att det föreligger vissa likheter mellan de problem som konceptet Knowledge Management angriper och de problem som en organisation ställs inför när man söker säkerställa att metadata hålls uppdaterat med hjälp av tydlig ansvarsfördelning.
