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.
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.
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.
Steget in i börsens ?finrum? : Så påverkas marknadsvärdet och likviditeten för bolag som väljer att byta noteringsplatsplats från alternativa handelsplatser till Stockholmsbörsen
Mellan åren 2001-2010 har 41 svenska aktiebolag valt att byta noteringsplats för sina aktier till NASDAQ OMX Stockholm (Stockholmsbörsen). Bytet har skett från de alternativa marknads- och handelsplatserna NASDAQ OMX First North (First North), Nordic Growth Market (NGM) eller Aktietorget. Det huvudsakliga syftet med denna studie är att undersöka om det finns ett värde för företagets aktieägare att företaget byter noteringsplats till Stockholmsbörsen. Detta syfte uppnås genom att undersöka hur listbytet till Stockholmsbörsen påverkar företagets marknadsvärde samt hur handeln i aktien påverkas. Då tidigare svenska studier (på Stockholmsbörsen) inom området är få eller helt saknas så är förhoppningen att denna studie ska ligga till grund som ett första steg för framtida forskning inom området. Tidigare forskning, främst utförd på de amerikanska marknaderna, visar överlag att företag som byter till en mera välkänd och prestigefylld börslista överavkastar marknadsindex tiden innan bytet för att tiden efter bytet underavkasta marknadsindex.
Social and economic consequences of wolf (Canis lupus) establishments in Sweden
Wildlife contributes with many benefits to humans but also brings economic costs. From being eradicated in Scandinavia the grey wolf (Canis lupus) is returning to South-Western Sweden and people are not used to its presence. In Scandinavia carnivores have to co-occur with humans in a landscape used for many different interests. Consequences of wolf establishments are e.g. competition for moose, depredation on sheep and attacks on hunting dogs.
Fastighetsmäklarbranschens rykte
Title: Real Estate Brokerage Industry's reputation - a study from a relationship marketing perspectiveLevel: Bachelor thesis in business administrationAuthors: Sanna Soininen & Sofia PulkkinenSupervisor: Jonas KågströmDate: 2013 ? AugustBackground: The background to this investigation was primarily another survey, conducted by Fastighetsbyrån, a Swedish real estate agency. According to the survey, only 5% of the Swedish population claims to have high confidence for realtors. The problem discussion revolves around statistics about how few real estate agents who are notified and receive sanctions each year. We believe that those numbers doesn't make sense when compared to how few people trust realtors, which is where our aim with the study comes from.Purpose: The aim of this study is to investigate the real estate brokerage industry's reputation by previous research in relationship marketing.Method: The study was conducted with a deductive and for the most part with a positivistic approach.
Bevarande av svensk låglandsboskap
Sweden signed, in 1992, the Convention on Biological Diversity (CBD) and has thus assumed responsibility for the indigenous biodiversity. That also means that Sweden has a conservation responsibility for the Swedish Friesian (SLB) (SJV, 2007a). In a survey conducted by the Board of Agriculture (SJV) in 1996, it appeared that there were around 780 cows and heifers of the SLB breed (SJV, 1997). SJV did in 2006 a plan for the development of livestock genet-ic resources and the number of cows of SLB was estimated at approximately 200. This meant that the SLB was in need of being conserved and SJV assumed it would be categorized as threatened.The primary objective of conservation of a breed is to reduce the loss of the original genetic variation (Lacy et al., 1995).
Seroprevalence and risk factors for bovine brucellosis, salmonellosis and bovine viral diarrhea in urban and peri-urban areas of Kampala, Uganda
Africa is expected to go through a rapid urbanization over the next four decades and the demand for food is increasing in the rapidly growing urban and peri-urban (UPU) areas. Keeping livestock in urban areas is in particular associated with health hazards. This is due to close interaction between humans and animals, and it has been shown that zoonotic diseases are increasing in urban areas. The benefits of urban and peri-urban agriculture (UPA) are related to improved food security, in particular among low-income groups. Apart from the negative public health impact of zoonotic diseases, animal disease could have a devastating impact on the economy and food security of many households in these areas.
In the present study, three important endemic diseases, including brucellosis, salmonellosis and Bovine viral diarrhea (BVD), were analyzed in regard to seroprevalence and risk factors.
