Skånes gröna guld : anläggning, odling & mossarter i mossträdgården

This is a 15 hp (10 p) thesis in biology at the programme for Horticulture Management at the Swedish University of Agricultural Sciences, Alnarp. In this literature study we have processed, reviewed and arranged facts and research, to make it more available for those who want to know more about establishment or cultivation of mosses. Our client is Fredriksdal?s Museums and Gardens in Helsingborg who are planning to establish a moss garden. The information is meant to be used by Fredriksdal and other similar facilities.

Samband mellan hull, underhudsfett, levande vikt och fruktsamhet hos SRB och SLB :

After parturition the energy demand for milk production is greater then the energy provided from the diet. The cow mobilises therefore body tissues to compensate for the energy loss. Live weight and body condition scores decreases as a consequence of the mobilisation. The aim of this study was to analyse the relationship between body condition score, live weight and subcutaneous fat depth measured by ultrasound and the changes during the lactation. Possible differences between Swedish Holstein (SLB) and Swedish Red and White Cattle (SRB) were also investigated.

Stengrunder och gränser : en studie av kontinuitet från äldre järnålderns stengrundsbygd till nutid

This thesis studies settlement continuity on Gotland between approximately AD 200 and AD 1700. The method used is to calculate correlation between the geographical distribution of all known Iron Age stone-wall-houses (on Gotland known as "kämpagravar") and all farms included in the detailed taxation maps from approximately 1700. The number of remaining house foundations is between 1800 and 1900. A model to estimate the number of removed foundations is presented. It is based on the assumption that the settlement density was proportional to land use around 1700, and that the rate of removal is related to the current land use.

Ett grönt möte mellan eklandskapet och en ny stadsdel i Linköping :

The purpose of this essay is to analyze and show possibilities how a city can grow into the scenery of a oak dominated landscape and how this encounter can add values to the city. The city in focus is Linköping, a city that is approaching one of Sweden?s largest oak dominated cultural landscapes. To this landscape high ecological and cultural values are connected. The recreational values are also of importance especially because of its urban location also because the city is mainly surrounded by flat agricultural land.

Trädens utveckling efter att de har lämnats som naturhänsyn : tillväxt, mortalitet och strukturell förändring 6-18 år efter avverkning

Today green tree retention, together with leaving dead wood, is a common practice with the aim to reduce negative impacts on biodiversity and environment due to clear-felling. To better understand whether this conservation practice also makes a long-term difference, it is important to know what happens to these trees after harvest. Few studies have made an assessment of what happens to retention trees over a longer time period. In this study I inventoried retention trees that were left at clear-cuts six, twelve and eighteen years ago. I carried out a re-inventory of 57 retention patches (divided into free-standing tree groups, small swamp forests and edge zones) and free standing dead trees, spread over 25 previous clear-cuts in central Sweden.

Willingness to pay for improved maize seeds among smallholder farmers : a study of the input factor market in Kenya

Kenya is considered to be a developing country. This means that basic needs such as nutrition are not met for an extended period of time (www, Sida 1, 2012). Approximately half of the population is living under the poverty line (www, CIA 1, 2012). Agriculture is the largest sector in the country, employing 75% of the population. These are thereby directly dependent on the sufficiency of outputs received.

A screening for Schmallenberg virus among sheep, goats and cattle in Zambezia province, Moçambique : and preparations for a metagenomic survey of virus in mosquitoes

As the world´s population increases and people's living conditions are improving, larger areas are needed for houses as well as food production. This means that new areas are exploited and that people, livestock, blood sucking insects and wild animals are forced to live close together. In combination with the global warming, leading to extreme weather such as floods and storms, this allows both new and old pathogens to emerge. The number of "emerging infectious diseases", EIDs, has increased in recent years and many of them have their origin in poor, tropical countries. Moçambique is therefore considered to be a high risk area for EIDs. Schmallenberg virus, SBV, was discovered in 2011 as an "emerging infectious disease" in dairy cows in Germany.

Trädgård - en angelägen fråga : Carl Adam von Nolcken, Jordberga gods och trädgårdskulturens främjande i Skåne 1834-1857

Baron Carl Adam von Nolcken was born in 1811. In 1834 he took over Jordberga Estate in the South of Skåne from his father. The estate remained in his possession until his death in 1857. von Nolcken was interested in agriculture and horticulture from an early age and attended the newly started Institute of Agriculture, Degeberg in Västergötland in the early 1830:s. At Degeberg, von Nolcken learnt all about modern farming methods, which he put into practice on his own estate. von Nolcken was one of the persons who during the mid 19th century worked intensely to develop horticulture and the art of gardening in Skåne.

Miljöarkeologi i Umeå stads hamn och slagfältsarkeologi på Krutbrånet : Två fallstudier inom historisk arkeologi i Umeås 1800-tal

This master thesis deals with two case studies in environmental archaeology and battlefield archaeology focusing on two major events in the late history of the Swedish coastal town Umeå and its nearby village Sävar. Established in the early 1600's, Umeå was known for its export of timber and import of cereals. The town has suffered from numerous fires, the fire in 1888 being the most devastating. Few written records of the town remain from before the 1900's. The latest war in Sweden's history is documented in historical sources and took place at Krutbrånet, Sävar where the Swedish troops suffered defeat against the russian forces in 1809.

Den ekonomiska lönsamheten för solvärme i Sverige

The sun is an endless energy source and the heat it produces can be used to heatup our homes. This technology is relatively old and was introduced in the late70-s. There are two kinds of solar collectors that are most frequently used todayand these are plain solar collectors and vacuum solar collectors. The plain solarcollectors are the once that are used the most but the vacuum solar collectorshave increased more as a percentage the last couple of years.The biggest question asked regarding an investment in solar heating is if theplant is economically profitable. This question has no direct answer because itis dependent on a couple of prerequisites.

Stadsodling : möjligheter och begränsningar

Urban farming can be viewed in several contexts. The first part of this work brings up the beneficial effects of farming on our physical and mental health, knowledge as well as on social life in cities. The introduction of gardening in schools can contribute to an increased awareness on both agricultural practices and importance as well as ecological processes. It can also be used in teaching of other subjects. Farming can also contribute to improving the household economy, and the economy on a municipal or national level.

Den villfarande studenten. Rättsprocessen mot Erik Molin 1734-1739

This study investigates the judicial process against Erik Molin, a clerk and former theology student at the University of Uppsala 1734-1739. The main purpose has been twofold; first to investigate the legal process through the various judicial bodies and secondly to analyze the ideas and conceptions about man and society expressed by the authorities and Erik Molin. The theoretical approach has been inspired by the German philosopher Jürgen Habermas? theories concerning the emergence of the bourgeois society and the changing concepts of private and public spheres. The study shows that the diocese of Uppsala regarded Molin's theology as heretic and found that he knowingly had tried to spread his views.

Trådlösa lokala nätverk : en utvärdering av prestanda

Dagens lokala nätverk förväntas tillgodose allt högre krav på prestanda, högre överföringshastigheter, men även mobilitet. Användare behöver allt mer tillgång till det lokala nätverket samtidigt som de ofta behöver röra sig inom arbetsplatsens områden. Till detta hör även de, i vissa situationer, krav på snabba uppkopplingar av tillfälliga nätverk, t. ex. vid konferenser.

Automatisk genreklassifikation : en experimentell studie

This thesis aims at examining to what extent a few, algorithmically very easily extractable document features can be used to classify electronic documents according to genre. A set of experiments is therefore carried out, using only 11 such simple features in an attempt to classify 84 documents belonging to electronic academic journals into three manually identified genres: table of contents, article, and review. The 11 features are also divided into three sets, containing metrics of words and sentences; punctuation marks; and URL links, respectively. The performance when using these sets of features is then measured with regard to classification accuracy, using a k-NN classifier, four different values of k (1, 3, 5, 7), and both leave-one-out and 10-fold cross-validation. Best results are achieved when using all three feature sets (i.e.

Blod, svett, tårar? och Word of Mouth? ? Att arbeta aktivt med Word of Mouth

Det blir allt svårare för företag att särskilja sig på marknaden. Traditionell marknadsföring är inte längre lika effektiv som förr, och idag finns flera olika strategier för att sticka ut i bruset. Kring varumärken och produkter skapas ofta ett rykte, som ibland antingen kan vara positivt eller negativt. Ibland har detta rykte uppkommit utan påverkan ifrån företaget, men det finns även strategier för att skapa och påverka sitt eget rykte. Ett positivt rykte kan leda till ökad försäljning och vinst.
