Den medeltida stadshamnen : Om strandområdets topografi och funktion i tre Öresundsstäder

This essay focuses on the function and development of city harbors during the middle ages in the Scanian part of Öresund. The purpose of the survey is to take a closer look at topography, development and activities on the shores in three coastal cities along the west coast of Scania. The cities that has been part of the survey are: Skanör ? Falsterbo, Malmoe and Landskrona, three cities that follows each other chronologically and that show both similarities and differences in appearance, function and urbanization.The cities of Skanör ? Falsterbo and Malmoe were important market places for the medieval Scania market with the herring fishery in focus. The cities? birth has to be looked upon in relation to these activities.

Sitkagranens potentiella merproduktion jämfört med vanlig gran i Hallands län

Sitka spruce (Picea sitchensis) is not considered to be a native species to Swedish forests. It´s origin is the pacific coast of Northern America, an area that is dominated by a coastal climate which makes it likely to believe that it would be well suited for growing in the south-west of Sweden. This study aims to investigate the gain in production that can be reached by growing sitka spruce instead of Norway spruce (Picea abies) in the county of Halland. A regression model based on data from forest experiments was produced to explain the gain in production. This model was based on elevation and annual precipitation. The model was then used to create a map layer in arcGIS that shows the gain of volume in comparison to Norway spruce in percent. An analysis was carried out to find what share of the forestland in Halland county that fell into four different classes of production gain.

Ansvar och engagemang - En studie av policyutvecklingen efter införandet av den svenska nationella strategin mot hotet från terrorism

I denna studie har policyutvecklingen av den svenska terrorismbekämpningen undersökts. Utvecklingen av den svenska kontraterrorpolicy sedan den nationella strategins introduktion, har ägt rum under en period när allmänheten och det politiska styret inte tillskrivit problemområdet samma betydelse. Medan allmänhetens oro ökat, har det politiska intresset kommit och gått. Med en fallstudiedesign har utvecklingen från 2008 års nationella strategi fram tills idag studerats och analyserats. Genom en kvalitativ textanalys har utvecklingen visat sig ha två trender.

Kustkommuners ovissa framtid : En fallstudie om sk?nska kustkommuners utmaningar med det stigande havet

Den globala medelhavsniv?n stiger och ?r ett o?terkalleligt fenomen som kommer forts?tta att stiga flera tusen ?r fram?ver. Studien syftar till att f?rst? hur kustkommunerna, Malm? och Trelleborg, resonerar kring strategier och anpassnings?tg?rder f?r att hantera utmaningar med havsniv?h?jningar, s?v?l som med r?dande styrning och ansvarsf?rdelningen. Studien unders?ker ?ven kommunernas syn p? havet och valet av tidsperspektiv i planeringen.? Resultatet fr?n studien visar p? ett behov av ett l?ngre tidsperspektiv, bortom 100 ?r f?r att m?ta utmaningarna med havsniv?h?jningar.

Rosenlunds bankar : Erosion och förändring sedan 1960

During the 1960´s and 1970´s the number of grey seals in the Baltic Sea was decreasing rapidly, mostly due to hunting and toxic substances like DDT and PCB. When hunting became less intense and toxic substances decreased in the environment the grey seal population started to increase. Today grey seals are found common in the Baltic Sea and have started to become a big treat and a problem to the fishing industry. The grey seal destroys and enters fishing traps and consumes large quantities of the fish that have been caught.The knowledge of the grey seal, like abundance and food preferences, is today limited. It is also important to define the position of the grey seal in the ecosystem in the Baltic Sea and to be able to predict changes that could occur if the population would rapidly decrease or increase.

Hur prissätts digitala dagstidningar i Sverige - En fallstudie om tre tidningars resa från gratis till betalvägg

Printed newspapers are on the decline, while digital versions are in rapid growth. Consequently the industry must draw up new business models around the digital format - models that can produce revenue streams equivalent to those that the print format used to produce. However, after a decade of 'free' online news, consumers now hesitate to pay. In their struggle for survival, strategic pricing is a central issue for newspapers. This study aims at describing how Swedish newspapers price their digital content, by analyzing their pricing processes and five factors that may influence the choice of paywall and price levels.

Den gotländska Stridsyxekulturen : migration, interaktion eller regionalitet?

This one-year master's thesis investigates the late part of the Middle Neolithic on the island of Gotland. This thesis has been written without the influence of a singular theoretical pespective, and has therefore seen input from the processual, and postprocessual theories. By using several perspectives, an attempt is made to view the material remains used in the most objective manner possible. The specific aim of this thesis is to investigate whether the Mid-Neolithic inhabitants of Gotland were a part of the Corded Ware culture (or as it is called in Sweden, the Battleaxe culture or the Boataxe culture). Most recent literature has concluded that Gotland was never a part of the Battlexe culture, though this thesis has discovered many parallels with the mainland culture, including the production of similar objects and ritual practices.

Sänkta sjöars inverkan på ytvatten i Västerbottens kustland : Samband mellan sänkningsnivåer och vattenkemi i sjöar på sulfidrika sedimentjordar

Lake lowering in sulphide-rich areas is currently a major environmental impact for surface water. This study focuses on whether there is a relationship between a gradient of lake lowering and surface water impacts in areas of sulphide-rich sediments, in order to better understand their contribution of heavy metals and sulfuric acid. Also, is it a reasonable method to use the reduced lake area in order to quantify the gradient? The survey was conducted by collecting water samples from reference lakes and lowered lakes from south to north in coastal areas within the county of Västerbotten. Water samples were then analyzed for TOC, pH, conductivity, anions, base cations, alkalinity, acidity, sulfate, Al, Cd, Fe, Mn, Cu, Zn and Pb.

Marknadsföra Innovationer: Hur länken mellan teknologisk innovation och värdeskapande är avgörande för framgång

Near Field Communication, NFC, is a short-range wireless communication technology that enables data exchange between devices in a secure way. A NFC phone has the potential to enable the convergence of wallet, phone and keys, but as many other technological innovations, the launch is struggling. We have discovered that technological innovation is only the first step. For an innovation to be adapted, there need to be business model innovation too. Many actors form the ecosystem of NFC and the business model for each service is still an unsolved problem.

Havsnivåhöjningens påverkan på Gotlands kust och strandängar år 2100

Den globala havsnivåhöjningen är en direkt följd av den globala uppvärmningen ochkommer i framtiden påverka stora områden i kustregionen. Syftet med detta arbete äratt öka förståelsen samt se hur Gotlands strandängar samt kustområden kan påverkas avhavsnivåhöjningen år 2100 och se vilka eventuella följder detta kan leda till. Metodernasom har använts är GIS-analys och litteraturstudier. Höjdmodeller med olika upplösningjämfördes även för att undersöka vilka som lämpar sig till en liknande analys införframtida studier. Resultatet visar att vid en havsnivåhöjning på 1 m kommer 97 % avstrandängarna försvinna och vid en havsnivåhöjning på 2 m försvinner 99 % av degotländska strandängarna.

Modellering av oorganiskt kol i boreal jord och vattendrag med hjälp av PHREEQC : Modelling of dissolved inorganic carbon in boreal soils and streams using PHREEQC

Syftet med examensarbetet har varit att studera kol i mindre vattendrag med hjälp av jämviktsmodellering i PHREEQC. Fokus har varit dynamik av löst icke organiskt kol (DIC) samt att förstå hur mycket koldioxid (CO2) som avges från mindre vattendrag och om den mängden har signifikant inverkan på den globala kolbalansen. Med hjälp av provtagen data från Krycklans avrinningsområde år 2003-2007 och 2009 har modellering av DIC och pCO2 utförts med målet att se förändring både över säsong och nedströms i ytvattensystemet. För att utvärdera modellen har tillhandahållen data över uppmätt pCO2 använts. Målet var att jämföra modellerade och tillhandahållna pCO2-värden för att se hur väl modellen kunde beskriva verkligheten och om den fungerade bättre för någon plats eller under vissa delar av året.

A risk analysis of moose close to roads

For many decades the increase in traffic volume, expansion of highways and infrastructure has lead to an increase of wildlife vehicle collisions which are unfortunately very common in many countries today. They cause great deal of material damage and even kill humans or wildlife. Measures in the form of warning signs, under- and overpasses and fencing have been implemented for a long time with the help of observation by hunters and collisions sites. However this study focuses on the moose?s perspective and the variables that, both spatially and temporally, could have an effect on why and when moose are close to certain types of roads.

Årlig gödsling med NPK bäst för gröda, miljö och ekonomi

Yesterdays common fertilizing strategy was to apply phosphor (P) and potassium (K) in thefall a few times in the crop rotation. In the spring only nitrogen (N) was applied. Recent trialsand studies has shown that this strategy, N+P/PK, is ineffective compared with the systemwhere NPK is spread every year in the spring. The strategy with annual NPK-fertilizer in thespring has proven to be better for the crop, the environment and the farmers economy.In the NPK-system the crop responds with higher yields and better quality, especially in thespring cereals. This is mainly because of an interaction between the different nutrients in thefertilizer.

Matregionen Södra Roslagen : en etnologisk studie om lokala beskrivningar av en regions mat

North of the city of Stockholm lies the area called Södra Roslagen composed of several municipalities. The purpose of this essay is to discover how local informants describe the food culture of the region and analyse why some types of food are mentioned and others are excluded. Several people within the food industry of Södra Roslagen were given surveys asking them to describe the food habits of the area, from commodities and certain dishes to traditions. These answers were analysed using the theories regional food, regiocentrism, revitalisation, placeless food and the idea of viewing culture through the long and the short perspective.One informant mentioned that professionals in the food industry of the region tend to follow trends from the rest of the world and another that many producers work with ecological requirements. Södra Roslagen was also defined by some as having a taste of summer as this coastal area sees an influx of visitors during that season.
