Leaf structure and localization of a transgene protein in barley

Barley is one of the most important cereals cultivated in the Nordic countries. Climate change brings warmer and moisture climate which favors fungal diseases. In the cropland barley can be seriously infested with hard fungus attack. Since it is important that the yield bears a high quality it is of great importance to find varieties more resistant to attacks.Pathogenesis-related (PR) proteins are stress proteins induced in the plant in response to infection and abiotic stress (van Loon, 1997). PRs are shown to have antimicrobial activity differing between bacteria, fungi and oomycetes (Tandrup Poulsen, 2001).

Välfärdsproblem hos mjölkkor i stora besättningar

The aim with the literature study is to inform about the risks that exists in large dairy farms(with focus on mastitis and hoof health) and to inform about the milk industry in Sweden.Personal comments from two study visits (Nötcenter Viken and Vadsbo Mjölk AB) arelinked together with the literature and forms into a discussion regarding sustainableagriculture versus the milk cow's welfare.The profitability for Sweden's milk farmers have decreased because of the decreased milkprice and current inflation. This leads to an increase in herdsize in order to make a profit.The milk cow herds in Sweden becomes fewer year by year and the herdsize increases. Theincreased herdsize can cause a decrease in the time the farmer spends per animal. This canaffect early disease Detection and prolong the animals suffering.Swedish Board of Agriculture published (2008) statistics showing that today's milk cow ismedicated primarily because of two reasons; mastitis or hoof problems. Mastitis is thereason to two thirds of all treatments that are carried out.

Echinococcus multilocularis in wild boar : aiming at an alternative surveillance method

This study was the first part of a larger project investigating a new surveillance method for Echinococcus multilocularis. In this study we examined livers from wild boar (Sus scrofa), looking for lesions caused by E. multilocularis. E. multilocularis is a small tapeworm which has an indirect life cycle.

Bärbara datorer, en möjlig källa för nickel- och koboltexponering av hud? : Direktvisande tester för nickel och kobolt på bärbara datorer och frisättningsförsök på en bärbar dator

Background: Since1994, the EU NickelDirective is limiting the release of nickel from objects that are in prolongedcontact with skin. Despite this, nickel is still the most common cause of contactallergy in industrialized countries. This could implicate that other productswith short contact to the skin, which are not restricted by EU´s legislation inREACH (Registration, Evaluation, Authorisation and Restriction of Chemicalsubstances), could be a source of nickel or cobalt exposure. There is no limitfor cobalt release within REACH. To determine if there is cobalt or nickelpresent on the surface of a material and if metal can be released in contactwith the skin, there are quantitative and qualitative methods, such as the DMG(dimethylglyoxime)-test, the cobalt spot-test and a method for releasedetermination according to EN1811.Objectives: Laptops are not included in the REACH legislation.

Brunstvisningsförmåga hos SRB- och Holsteinkvigor

Oestrus in dairy cattle has changed over the last decades, the duration has decreased and the intensity of oestrus has declined. A possible explanation can be their high and increasing milk production. Heifers ability to show oestrus is probably not affected to the same extent. The aim of this study was to estimate and compare oestrus duration and strength in heifers of the Swedish Red and Holstein breeds. Standing oestrus has been the primary oestrus sign during many years.

Potentiella virala zoonoser hos apor på svenska djurparker år 2008

This paper is a compilation of some of the important viral zoonosis that can be passed from apes and simians (simian and prosimian) to man. Viral zoonoses are viral diseases that can be passed from animals to humans. The paper will also provide a better insight of the risks workers and visitors to the zoo can be exposed to. The viruses that this paper is focused on is herpes Bvirus, simian T-lymphotropic virus type 1 (STLV), simian immunodeficiency virus (SIV), Ebola virus, Marburg virus, yellowfever virus, monkeypoxvirus and hepatitis B virus. The choice of viruses is based on how infectious they are and how pathogenic they are.

Analys av prostaglandin F2? -metabolit i blodet : indikativt för pyometra hos tik?

Pyometra (chronic purulent uterine inflammation) is a common disease in middle-aged and older intact bitches. The disease most frequently occurs in metoestrus and previous research studies have shown that both hormones and bacteria are involved in the development of the disease. Analysis of the blood levels of prostaglandin metabolite 15-keto-13,14-dihydro-PGF2? (PG-metabolite) has previously been shown to be clinically useful in the differentiation of canine uterine diseases such as pyometra and mucometra. The PG-metabolite concentration has also been correlated to severity in pyometra as determined by hospitalisation length. The purpose of the present study was to investigate if blood levels of PG-metabolite can differentiate uterine diseases such as pyometra from other diseases in female dogs.

Användning av LiDAR och ArcGIS inom skogsbruk i Sverige

Light Detection And Ranging (LiDAR) har under det senaste decenniet utvecklats mycket och används som datainsamlingsmetod vid inventering av skog. Lantmäteriet genomför mellan åren 2009 och 2015 en riksomfattande flygburen laserskanning över hela Sverige och den laserskanningen ska leda till en ny nationell höjdmodell (NNH). Data som genereras från denna höjdmodell kan nyttjas av skogsindustrin för att göra skogliga inventeringar. Programvaruutvecklaren Esri Inc. har utvecklat ett stöd för hantering av denna typ av data i deras nya version av ArcGIS, ArcGIS 10.1.

Hjälp i tid : En fallstudie av pedagogers tidiga insatser i åk 1 för att förebygga läs- och skrivsvårigheter

Syftet med fallstudien var att studera hur lärare, speciallärare och specialpedagog beskriver sitt förebyggande och stödjande arbete med att tidigt upptäcka och åtgärda läs- och skrivsvårigheter i åk 1. Vi har genom kvalitativa intervjuer med två lärare, en speciallärare och en specialpedagog fått en ingående bild av hur detta arbete ser ut på två olika stockholmsskolor. Utifrån pedagogernas intervjusvar tycker vi oss kunna säga att teori och praktik stämmer bra överens och mycket av det som vi har läst i litteraturen verkar också praktiseras ute på de två skolor som vi har studerat. Studien har visat att pedagogerna inte använder sig av ?vänta-och- se?- pedagogiken för att barnens läsning ska komma igång av sig självt utan de menar att de arbetar medvetet förebyggande och med tidiga insatser när det gäller barn som ligger i riskzonen för läs- och skrivsvårigheter.

Lactobacilli in the gastrointestinal tract of dog and wolf : isolation, identification and characterization of L. reuteri

Since the first wolf was taken as a companion animal a lot have happened with the biology of these animals. Is it possible that changes in the gut microbiota of the domestic dog are involved in the increasing numbers of animals with gastrointestinal disorders? Probiotics have been proven to promote the immune system of dogs by increasing concentrations of neutrophils and monocytes, decreasing the fragility of erythrocytes and increasing the serum IgG concentrations. Probiotics have also been shown to improve the fecal consistency, fecal dry matter and defecation frequency of dogs. The aim of this study was to find out if the bacterial counts in the gut of dogs differed from the gut of wolves, with the focus on lactobacilli.

En jämförelse mellan amplifierad singelmolekylanalys och selektiv agar vid kontroll av hygienisering av avloppsslam

Bringing back the nutrients from the city to the country is becoming increasingly important, as the world?s stores of nutrients get more exhausted. Sewage sludge is an unapplied resource, rich in plant nutrients, which could replace parts of the commercial fertilizers used in Sweden today. Sewage sludge may contain large amounts of pathogens, such as Campylobacter and Salmonella, why use can cause severe spreading of infections, both to animals and humans. These pathogens have the ability to survive for a long time in soil and water and therefore some sort of treatment of the sludge is recommended before use.

Höjdmodellering med laserdata : Studie av Kärsön, Ekerö med fokus på upplösning, datalagring samt programvara

The New National Elevation Model (NNH) is a new high-resolution digital elevation model (DEM) of Sweden from airborne laser scanning. It creates many new opportunities, particularly in the area of flood mapping. NNH is provided by Lantmäteriet in two formats, both in raw LIDAR (Light Detection and Ranging) data and in grid format with two meter resolution. These alternatives have advantages and disadvantages and the aim of this thesis research is to identify these. One of the focuses of the study is data storage and thus data structure analysis, resolution and storage facilities. The research questions are:Why and in what context the different NNH-products from the National Land Survey are used (DEM 2+ or point cloud)?What constraints and opportunities are created by the different options, mainly in terms of different software, resolution, and data storage?The study area is Kärsön in Ekerö municipality located in Stockholms län and has an approximate area of 25 square kilometers. The study is divided into two parts. The first objective is to identify the consequences of using different software to create DEM from pointcloud compared to the DEM2+ model. Height models with a two meter resolution are created in FME and ArcGIS. The models are then compared with the grid from Lantmäteriet, created in TerraScan. The second objective is to examine the impact of the change in resolution, both the storage aspect and both the accuracy aspect. Inverse Distance Weighted (IDW) is an interpolation method which in previous studies proved to have the best results on high resolution LIDAR data. This model was tested and compared with a model from FMEs built-in function and the model from Lantmäteriet wich are based on triangulation (also proved a good method in previous studies). The grid created in TerraScan has good properties such as accuracy.
