Storlommens (Gavia arctica) häckningsframgång relaterad till vattenkvalitet

This work investigates the breeding success of the Black-throated Diver, Gavia arctica, related to the water quality in three lakes located in the Vallentuna area, north of Stockholm, Sweden.For more than 30 years, I have studied the bird life around these three and other nearby lakes, and noticed that the Black-throated Diver breeds in some lakes, but not in others.The results confirm that the deep and clear lakes Tärnan and Stora Harsjön have good water quality regarding pH, alkalinity, aluminium and Secchi disk values. As expected, the Black-throated Diver shows breeding success in those two lakes, but does not breed in the shallow and eutrophic lake Mysslingen. .

Hypertrofisk kardiomyopati hos Maine coon katter :

Hypertrophic cardiomyopathy (HCM) is the most common heart disease in cats. Maine coon is one of the breeds where the disease is overrepresented. Studies have shown that HCM is inherited as an autosomal dominant trait in Maine Coon cats. This finding has led to cardiac screening using ultrasound in the breed. The results of the screening are used in a national breeding program constructed to reduce the spread and incidence of HCM in Maine Coon cats.

Hovbroskförbening hos svenska ardennerhästen :

Ossification of the collateral cartilages of the distal phalanx has been studied primarily in cold blooded horses. The clinical relevance of this condition is unknown. Despite this fact, since 1939, all Swedish Ardenner stallions have had to be classified as being free from this ossification to be approved for breeding. Initially, palpation was used as a diagnostic method, but since 1982 radiology has been the only method used. The aim of this study was to assess the outcome of 68 years of breeding program. Dorsopalmar radiographs were taken of the front feet of 58 Ardenners (30 mares, 8 geldings and 20 stallions) and the ossification of the collateral cartilages was evaluated and graded according to three different scales; - Ruohoniemi (grade 0-5), - Swedish University of Agricultural Science (grade 0-3), - and a new scale (grade 0-3), developed for this study.

Från vilda till domesticerade djur - kan man gå ett steg längre?

Domestication has resulted in the ability for animals to adapt to environments created by the human over time. The behavior differs very little between wild and domesticated animals, but the difference seen is how often and to what degree a behavior is performed. The need for efficiency in modern animal production has led to welfare problems in the productionsystems where the animals have difficulties coping with their environment. Attempts to environmentally adapt individuals by selection for reduced frequency of natural behaviours have been made. These have shown that natural behaviours are complex and are controlled by several different mechanisms, making selection for reduced natural behavior difficult, and it may also lead to unwanted and abnormal behaviours.

Utvärdering av vibrationer inom vattenkrafts normer

The International Organization for Standardization (ISO) proposes vibration standards for the evaluation for machine damage due to vibration in rotational machines, where some vibration parameters are given to measure the vibrationgrade. This work evaluates the relevance of the vibration standards in hydro plants that are proposed by the ISO, and also investigates if there are methods used in other countries could have greater importance. Through statistical analysis of collected data we got a better understanding of relation among different vibration parameters, and also the importance of correct choice of the parameters for the evaluation of vibration. We have found that the vibration standards available today in hydro plants are not reliable for the judgment of vibration?s grade.

Utvärdering av Politiskt Bistånd : En fallstudie av ett politiskt biståndsprojekt i Laos

The findings in this case study are mainly based on material collected during a field trip with a fellow student to Laos in February-March 2005, which was sponsored by Sida through a Minor Field Study scholarship. The original interest was to study a political aid project (Governance and Administrative Reform Project Luang Prabang, GPAR LP) in a country like Laos with very complex preconditions such as one-party polity. In Laos my interest in evaluation of political aid grew mainly because I found out that the two donors in the project, Sida and the UNDP, had reached different conclusions in their respective evaluations of the project.The main interest in this thesis has been to study how donors have evaluated a political aid project. The study shows that Sida and UNDP used, what in the literature usually is referred to as, Conventional evaluation as methodology when they conducted their evaluations of GPAR LP. The study also shows that the main reason for the different points of view that are expressed in the evaluations depend on a lack of dialogue and consensus, regarding for the project crucial concepts, rather than choice of evaluation methodology.

Värdering av anbud vid kommunala upphandlingar av byggprojekt

The thesis deals with evaluation of tenders for communal construction procurement. Each year the public procurement equals the value of millions of Swedish kronors, of which construction projects makes up a large proportion. These projects tend to often exceed their budgets. The aim with the thesis is to investigate if there are faults in the tender evaluation process. The theoretical framework for the study partly consists of a review on how the communal evaluation work is described in law and practice.

Syringomyeli hos hund

The canine population has during it?s time with humans gone through at least 2 major genetic bottlenecks, the first when it was separated from the wolf, and the second when it was divided into different breeds. Among other things, this has lead to the accumulation of unwanted genes, such as genes causing disease in dogs. One such inherited disease is syringomyelia, which has proven to be more common than expected, especially in certain smaller breeds such as the Cavalier King Charles Spaniel. Syringomyelia in dogs is often a secondary condition caused by the malformation called occipital hypoplasia.

Lactobacillus reuteri som probiotisk terapi mot bakteriell vaginit hos avelsråttor :

Lactobacillus reuteri has been used as probiotics in piglet and chicken feedings as well as in different diary products for humans. In this EEF-work I have shown that L. reuteri can be an alternative for treatment of vaginitis in laboratory rats used for breeding. In a breeding stock with 3000 animals some animals had a vaginal infection with ??haemolytic streptococci group G.

Analys av dräktighets- och fölningsresultat inom svensk varmblodig ridhäst och svensk varmblodig travhäst åren 2000-2006

The purpose of this thesis was to analyze conception and foaling results of Swedish warmblood and Standardbred trotters using breeding statistics during the years 2000-2006. Key issues in this thesis were: Have the conception and foaling results of stallions changed during the period 2000-2006? What is the effect of the use of various breeding methods? Is testicle size correlated with conception and foaling results? How important are age, breed and level of inbreeding of the stallion for conception and foaling results? Breeding statistics were available for 537 Swedish Warmblood stallions and 305 Standardbred trotter stallions. To be included in the analyses, a stallion must have mated at least ten mares in total over the period 2000-2006. This criterion was met by 313 Swedish Warmblood stallions and 272 Standardbred trotter stallions.

Utvärdering av Skvallertorget i Norrköping

This thesis is an evaluation of the new traffic solution at ?Skvallertorget?. The innovative theory behind it is to increase traffic-safety by introducing insecurity feelings for road-users. The conclusion of the evaluation is that the newtraffic solution is well adjusted according to guidelines for municipal traffic planning. The evaluation also illustrates the conflict between traffic planners deliberate attempt to avoid clear information and the road users wish to get it.

Phenotyping of Bali cattle and interviewing farmers in Indonesia - a minor field study

Among the Indigenous cattle breeds in Indonesia, the Bali cattle is the most preferred by small farmers. The Bali cattle is a beef breed, and is considered to have several advantageous characteristics and to be well adapted to the country?s harsh environmental tropical conditions with drought and rain. The main aim of this project was to phenotype of Bali cattle from different locations in order to identify and document diversity within the Bali cattle breed based on their observable characteristics, to compare cattle from different areas and production systems to see the effect of management on phenotype. In this study, 107 cows and bulls of the breed Bali cattle, from Kalimantan, Sumatra, Lombok and Bali were phenotyped.

Tillämpning av utvärdering inom operativt förbättringsarbete

In the fall of 2014 a literature review and a scientific study of the topic; "... in the extent to which companies in the industry applies the evaluation of continuous improvement? was conducted at Mälardalen University. These studies are the foundation of this thesis.A strategic improvement is often divided into smaller steps of improvements at each hierarchical level from the top down through the organization. But if there is no response system that can confirm the results of these improvements back through the organization it is very hard to see if the improvements really are improvements or just changes and a waste of resources.

Kvighotell

In this essay I have summarized important factors for an effective, but also successful, way to raise and house heifers. This study can be used for other dairy farms to use as guidelines in their process to raise heifers. To let outside heifer growers house, feed and have the heifers pregnant before return, can save a lot of work. But also moneywise, when the care and individual programs makes them strong and increases the growth.The result is a faster breeding and an earlier time for their first calving.In Sweden the heifers tend to be older if you compare with Denmark or United States where the custom heifer raising is well known and growing. One reason can be the Swedish laws regarding outside grassing for all cows during the summer months.
