Biologisk mångfald i små grönområden : Inventering av insekter och fåglar i bebyggda områden i Solna kommun

All over the world the urbanisation increases at the expense of green areas. Many plants and animals are endangered today because their habitats gets smaller or disappear. The green areas that are left in city centres and suburbs are often small and surrounded by roads and buildings. Despite this, several studies have shown that these small green areas may house large biological diversity.This project aims to study the biological diversity in small green patches in residential areas. The study has been carried out in Råsunda in Solna municipality (Stockholm county) during the period May?July 2006.Three equivalent areas (5000?10 000 m2) with quite many old oaks were chosen for the study and inventoried for birds and saproxylic insects.

Utdelningsmönster i en internationell kontext : - En jämförelse av tre EU länder

Syftet med uppsatsen är att studera sambandet mellan länders utdelningsmönster och corporate governance system samt förklara varför denna koppling ser ut som den gör med hjälp av den teoribildning som finns på området.Till undersökningen har tre EU länder valts. För att kartlägga ländernas utdelningsmönster har finansiell data insamlats för respektive lands samtliga noterade företag. Dessa data har sammanställts till tre nyckeltal gällande utdelningsnivå för varje land och år mellan år 1989 till år 2007.Det finns skillnader mellan länderna både beträffande corporate governance system och beträffande utdelningsmönster. De viktigaste faktorerna inom corporate governance som i uppsatsen visat sig haft störst betydelse för utdelningsmönstrets utseende är ägarstrukturen samt kapitalmarknadens struktur. Störst andel spritt ägande och starkast inflytande från aktiemarknaden återfinns i Storbritannien, följt av Sverige och sist Tyskland som tvärtom kännetecknas av ett mycket koncentrerat ägande och lägre påverkan från aktiemarknaden.

Hund som komparativ modell för autoimmuna sjukdomar :

In this essay dog as a compatible model were put against human. The major histocompatibility complex (MHC) genes were compared between dogs, human, cat and mouse. To evaluate dog as a model and study similarities and differences was the aim with this review. Dog as a model contributes to understand mechanisms behind autoimmune diseases and showed clearly histological similarities between human and dogs concerning the skin disease mucous membrane pemphigoid (MMP)/cicatricial pemphgioid (CP). Further genetic evidence motivated the choice of using dog as a comprehensive model when the MHC-complex correlated with hypothyroiditis in Doberman dog as it does in human. Physiological similarities with low levels of thyroid hormones (T3 and T4) together with high level of thyroid releasing hormone (TSH) were found in the same way as in human.

Tarmflorans påverkan på fetma

Obesity is a problem that increases exponentially in humans and companion animals. It is defined as a big accumulation of fat in the body and is usually connected with several diseases. This study describes how obesity can be diagnosed, in which way the gut flora can affect obesity, if the gut flora is genetically influenced or not, and how it differs between individuals with obesity and obesity-related diseases. Conclusions of the study are that both the bacterial strains Bacteriodetes and Firmicutes probably have a connection to obesity. The intestinal flora is probably also genetically related.

Emerging infectious diseases : a model of disease transmission dynamics at the wildlife-livestock interface in Uganda

Emerging infectious diseases are a recurring threat to both human and animal health. Understanding the multiple causes behind the emergence of new diseases is key to the prevention of new and potentially devastating outbreaks. The list of underlying causes is long, including a variety of anthropogenic, environmental, molecular and climatic changes that promote the emergence and spread of disease. Two of these factors are central to the emergence of new diseases and receive special attention in this study. The spread of disease from wildlife to livestock and diseases that spread from animals to humans (zoonoses) are of importance as they implicated in the majority of EID events.

Leksaker för alla : Kiwi Bird Box

Utifrån temat Hållbart Samhälle och aspekten Socialt Hållbart Samhälle, är denna uppsats en berättelse om ett examensarbete som tagit sig an leken i förhållande till funktionsnedsättningen autism hos barn och där frukten av examensarbetet blivit en leksaksprodukt.Med hjärta, hjärna och engagemang har jag undersökt utifrån mina användare hur jag kan skapa en artefakt med potential att ge mina användare förutsättningar som de behöver för att leka, samspela och kommunicera. Men även andra barns behov i lek, samspel och kommunikation har varit viktiga att tillgodose då målet har varit att möjliggöra det sociala samspelet mellan båda dessa parter. Med andra barn menas barn oavsett funktionsnedsättning eller ej. Målet har därmed även varit att formge en leksaksprodukt som möter dessa två parters behov, såväl till form som funktion. Visuellt ska leksaksprodukten inte ge något uttryck av hjälpmedel, utan ska snarare vara en leksak som dolt kan tillgodose behoven hos barn med autism.Examensarbetet har även varit en möjlighet för mig som designstudent att få lära mig om hur företag arbetar med design för barn, vilket har lett mig till företaget BRIO AB som givit sina erfarenheter samt åsikter till leksaksprodukten.

Samband mellan hög incidens ämnesomsättningssjukdomar och klövhälsa hos svenska mjölkkobesättningar :

Metabolic diseases in dairy cows are considered to increase the risk for claw lesions, most of all laminitis, sole haemorrhages and sole ulcers, but also to increase the risk for environmental claw lesions. The aim of this study was to compare claw health in 27 Swedish dairy farms, 18 with high incidence of metabolic diseases and 9 with low incidence. Data on claw health status was retrieved from recordings at routine claw trimmings and analysed on herd level regarding the prevalence of: any lesion, interdigital dermatitis, heel-horn erosion, sole haemorrhages, sole ulcer, lameness, abnormal claw shape, and other diseases (abscess in the white line, limb disorders, double sole, laminitic groove, white line disease, interdigital phlegmon, interdigital hyperplasia, toe abscess and verucose dermatitis). Mean prevalence of any lesion for herds with low incidence of metabolic diseases was 48 % and in herds with high incidence 41 %, and there was no statistical difference between the two groups. Mean prevalence for interdigital dermatitis was 2,0 % and 6.4 % in the low and high incidence groups, respectively (p.

Hydroperikard hos katt : patofysiologi, diagnos och behandling

Hydropericardium or pericardial effusion (PE) is the accumulation of fluid in the pericardial sac and is often secondary to pericardial diseases or diseases related to the heart. It is unusual with clinically relevant pericardial diseases in cats but pericardial effusion is the most common one. Since PE causes serious symptoms and may lead to death it is important with a quick diagnosis and treatment. PE can be acute and cause cardiac tamponade, which gives severe clinical signs. Cardiac tamponade needs to be treated immediately or else the cat will die from cardiogenic chock. More common is chronic PE where the fluid accumulates during a longer period of time and the pericardial sac stretches.

Mellan makt och myt : om gravritual och brända ben från en småländsk vikingatida gravhög

For this essay, 12 liters of cremated bones from the Viking age grave mound RAÄ Berga 134:1 in Trotteslöv, Berga parish, Småland have been osteologically analysed.  The aim with this paper concerned questions as sex, age, number of individuals and animal species in the grave. Further questions that have been investigated are the relationship between the osteological sexdetermination and artifacts as well as which role animals played in burial rituals and as grave goods.The grave contained a middle-aged woman and a number of sacrificed animals: two horses, two dogs, three birds, a boar and a cat. The bones were fragile and very fragmented. One of the birds was determined as a bird of prey, and that together with findings of horses and dogs indicates hunting with bird of prey, an activity performed only by powerful and wealthy individuals.  The woman was buried in a mound of notable size, and with common grave goods for the time period: combs, beads, bronze and iron items. An unusual finding was textile which indicates high status. The number of sacrificed animal species also suggests that the grave belonged to a powerful individual. During the Viking age animals generally played an important role in grave rituals and as items to be used by their master in the next life.

Pepparmyntans bioaktiva ämnen - hur påverkar de människors hälsa?

Since early civilization, herbal tea has been used as remedies for an abundance of different diseases. Among these herbal remedies, peppermint (Mentha piperita) was used for its effect on bowel related ailments. Even though peppermint was not described until late 17th century, it has been used since 1000 years before Christ by the Egyptians. In present day it is still considered a remedy for stomach pain etcetera, and much of the recent research is concentrated on the positive effects of peppermint on pain and bowel diseases. A large section of the research is also reviewing positive effects of peppermint on cancer, allergy and also on its potential as antibacterial agent.

Zoonotic Pathogens at the Interface between Humans and Animals in Cambodia, a Rural Approach

A zoonosis is a disease or infection that is naturally transmitted between vertebrate animals and humans. The majority of infectious diseases that affect humans are zoonoses. Environments where wild animals, domestic animals and humans live in close proximity with no or small boundaries in the ecological system favor the transmission of diseases between animals and humans. The above described situation is more common in low income countries, where humans and animals live in high density and zoonoses are generally more common. The study was conducted in Cambodia.

Djurägarbehandlingar inom renskötseln :

The aim of this study was to document treatments of sick and injured reindeer in Tornedalen and the area around Gällivare. I also wanted to find out the basis for the treatments, how they are considered to work and if they agree with established veterinary science. The occurrence of ?folk remedies? was especially studied. In all, 40 reindeer owners were interviewed.

Profylaktiska åtgärder för kaniner

Rabbits, Oryctolagos cuniculus, rapidly increases as pets. During the right circumstances, rabbits are friendly, social and playful. A rabbit who shows an abnormal behavior should always be examined by a veterinary, though there is almost always a medical problem. This essay is a result of a literature studie with the aim to find the prophylactic measures that may give pet rabbits a more healthy life. Rabbits have got a lot of common health problems, including dental, skin and gastrointestinal problems.
