Diskursanalys på den Etiopiska regeringens nationala handlingsplan om bekämpning av ökenspridning
In this paper discourse analysis on the Ethiopian National Action Program (NAP) to combat desertification is made. The aim is to describe how the overall image/picture of desertification, its causes, and effects and of possible solutions are presented in the NAP. The result of this analysis shows that the main cause of desertification is human activities mainly due to the poorly developed socio-economic situation in the dryland areas. It is indicated that an excessive dependency of the rural population on the natural resources, particularly land, is the major cause of land degradation and this deterioration of land is said to have been caused by the rapid population growth, overgrazing, forest clearing as well as past government and institutional failures. In addition it is indicated that the effect of desertification usually involves ecological changes that sap land of its ability to sustain agriculture and human habitation, therefore the most serious threat to human welfare.
Digital kompetens : Äldreomsorgspersonals upplevelser av en digitaliserad arbetsplats
This study highlights the importance of computer technology and its impact on elder care staff's skills development in the public sector. The government presents the digital agenda within which information and communication technology today is considered to have a potential for sustainability, growth and development. According to the EU Commission, there are several important elements that should be improved to digitize the workplace. Among these are digital literacy, collaboration between agencies and increased investments in research, education and innovation. New technology can be understood in different ways by individuals, some see the computer as something positive and exciting, while others may find it hard to see the opportunities for learning and development.
Skogsfastigheters totala produktionsförmåga som förklarande variabel vid prissättning
Sedan marknaden för lantbruksfastigheter avreglerades i början av 1990-talet så har priserna på skogsmark ökat kraftigt. Då priset på timmer och massaved inte ökat i samma takt råder år 2014 en situation där priset på en skogsfastighet är högre än dess avkastningsvärde. Detta gör frågor som rör skogsägarnas värdering inför köp av skogsmark högintressant.
Tidigare studier inom samma område har haft som mål att fastställa vilka faktorer som har en inverkan på fastighetspriset. Bonitet och produktiv skogsareal är två grundläggande faktorer som beskriver fastighetens karaktär. Ändå har det ibland visat sig svårt att hitta ett statistiskt samband mellan dem och fastighetspriset.
Gallringsinventering från helikopter utrustad med profilerande laser och kamera för låghöjdsfotografering
Today Holmen Skog finds and selects suitable thinning stands using data on upper height and basal area. These figures are often based on basic forest data that has been updated with the help of growth prediction models. The problem is that these figures are not always correct. The aim of this study was to investigate if a combination of data from a profiling laser and a digital camera for low elevation photography, can be used for collecting data on number of stems per ha, tree species mixture as well as basal area weighted mean height and upper height for stands. The possibility to use these data to assess the need for thinning cutting was also investigated.Laser data and aerial photographs were collected from a helicopter operating at an approximate height of 100 meters.
En inventering av säregna trädformer funna i Sverige
In Sweden and in Scandinavia the amount of tree species are rather few. However many different forms of trees arise due to mutations and gives rare appearances like cut-leaved and hanging forms. In some cases these trees are interesting as cultivars and a few of them have become popular garden trees. The knowledge of the original trees and early propagation is meagre.In this study a selected group of trees were found through search of literature. Eight tree forms were chosen and investigated in situ.

This master thesis has been written in collaboration with Science Park Jönköping and is based on a problem related to corporate innovation. Science Park Jönköping believes that there is an untapped potential in existing industry in the form of ideas that are never commercialized. These theories are also supported in the research in which other authors have perceived that the ideas and inventions which do not belong to the core business risk ending up in drawers. If more of these ideas could be spin-offs or other forms of enterprise instead of staying in the drawers it would lead to growth, both for companies and for the society in large.The purpose of the thesis work is to, based on the case Science Park Jönköping, analyze how science parks and incubators can support the commercialization of ideas that derive from industry, who otherwise had been left lying. The work began with a mapping of the Science Park Jönköping operations and the skills they possess, and then other initiatives that aim to commercialize more ideas from companies were examined.
Högutbildade ekonomistudenters minskade intresse för eget företagande : En studie av Företagsekonomistudenter på Södertörns Högskola
AbstractTo benefit the economic growth of a country, it is important for the inhabitants to make the decision to become business owners. Sweden today, apart from the rest of Europe, is facing a growing problem. The numbers of companies are growing, but the numbers of company owners are not. As a result of this, the employment is not able to develop under the same conditions, when the opportunities of employment decrease. Research shows, that the interest for owning a company among the Swedish youth has increased.
Är direktägda bostadsfastigheter en bättre investering än aktier? : En studie över riskjusterad avkastning
Background:Investments in different forms have always been popular to every human being. For the most common investments, such as stocks and bonds, there are loads of information to gather for the investor. Historical data like risk, return, dividends and fundamental data like annual reports are often very easy to find, regarding these kinds of investments. The background of this thesis is the lack of market information in residential real estate investments. A problem with this investment is that there is lack of information regarding risk adjusted return for real estates, which this thesis intends to present.Objective:The objective with this thesis is to study which alternative, directly-owned residential estates or stocks, who generates the highest risk adjusted return.
Kartläggning av stallbyggnader och djurhållningssystem inom mjölkproduktion ur salmonellasynpunkt
Promoters are genetic elements that facilitate the transcription of a gene and they have been found in front of non-coding RNA (ncRNA) genes in different organ-isms, e.g. the model plant Arabidopsis thaliana. A similar element, DUSE, has been found in front of ncRNAs in the social amoeba Dictyostelium discoideum and a part of this project has been to analyze the function of this putative promoter element through cloning and expression studies. A construct to analyze the func-tion of DUSE was successfully designed and introduced into D. discoideum but full expression studies were not finished because of shortage of time.
Vaselin som kontroll vid försök med 1 % väteperoxidkräm i färska hudsår på häst
Wounds on horses are common and sometimes difficult to treat. The wounds are often big and could be discovered too late for primary sutures, which have to be applied within 8 hours from time of accident, before bacteria has been able to infiltrate the surrounding tissue. The healing is often complicated by delayed healing and wound infection with consequences like phlegmone, fistulation and proud flesh formation.To avoid these consequences, the traditional practice has been to administer systemic antibiotics alone, systemic antibiotics in combination with topical antibiotics or topical antibiotics alone. Because few antibiotics can be used in horses, is it important to household with the few substances that are available. In veterinary medicine today, the increasing resistance amongst pathogenic microbes such as MRSA presents a growing problem.
Fördjupad miljöriskbedömning av förorenade markekologiska system. : Integrering av kemisk, toxikologisk och ekologisk information.
AbstractThe research project Liberation, supported by the European Commission under the Environment and Sustainable Development Programme (Fifth RTD Framework Programme) aimed at developing a decision support system for ecological risk assessment of contaminated sites has proposed a tiered system including the triad method. This method integrates contaminant chemistry and bioavailability analyses with observed ecotoxicological effects in soil and groundwater. In this study the triad method was used to perform a risk characterization of a former surface treatment and metal industry, now used for the student union buildings of the Mälardalen University in Eskilstuna, Sweden. On the site, high concentrations of copper, zinc and nickel have been detected in the soil in a preliminary investigation of contaminant levels with XRF. For performing the risk assessment of the site according to the triad method, contaminant bioavailability, soil metal concentrations and soil toxicity were determined and an ecological assessment was carried out on four selected soil samples (one reference soil and three samples with low (B), medium (C) and high (D) contaminant levels). Contaminant bioavailability was measured through leaching (ISO TC 190/S7) and biouptake tests (DGT).
Importance of epigenetics in animal breeding : genomic imprinting
ABSTRACTThe aim of this study was to give an overview of the evidence for genomic imprinting in livestock and other mammals as well as outline the potential use of gene imprinting in livestock breeding. Epigenetics is the mitotical and meiotical partial hereditary variation in genomic activity without any alterations of the DNA sequence. An example of epigenetic regulation is genomic imprinting where one allele?s expression differs depending on which parent it was inherited from. These parent-of-origin effects are currently overlooked in livestock production.
Utveckling av metod för retrospektiv bestämning av absorberad dos i korall medelst elektronspinnresonans
This diploma work was performed at the department for radiation physics at the Health University in Linköping. Its aim was to develop a method to retrospectively quantify the absorbed dose in coral. Coral is a material which suites well as a retrospective dosimeter because when exposed to radioactivity its induced free radicals are stable in time. The number of radicals is proportional to the accumulated dose so the dose can be calculated by quantifying the radicals. Therefore, coral can tell us something about the past environment and also be used in dating purposes.A young, modern coral from the Red Sea was studied and also a fossil one which I was given from the Natural History Museum in Stockholm.
Controlled traffic for grass silage production : an economic evaluation for dairy farmers
The farm management system controlled traffic farming (CTF) aims to reduce soil compaction by restricting the field traffic from agricultural machinery to permanent traffic
lanes. Literature and empirical findings show that soil compaction and field traffic from heavy machinery may affect crop growth negatively, reducing crop yields. If grass-clover leys are subject to heavy field traffic the botanic composition might be altered, providing a lower
clover content in the forage. Clover as a silage feed is rich in protein providing good conditions for high yielding dairy cows. Grass-clover silage production is generally associated with intensive field traffic.
Riktad avmaskning mot spolmask på föl
Infection with Parascaris equorum is common among young horses in Sweden as
well as in the rest of the world. The parasite has a direct lifecycle and reproduces in
the small intestine. The eggs are passed out with faeces and become infective after
approximately two weeks. The horses get infected when they ingest eggs that are
dispersed in the environment. The symptoms seen in horses usually include
retarded growth and loss of weight.
