Aerated steam treatment is a modern and environmental friendly method for seed borne fungus sanitation, mainly used on cereals. The method involves exposure to heat and high humidity, factors which are known to induce a fast ageing of seeds, thus resulting in reduced storability. This thesis clarifies the interdependence between seed age and the aerated steam treatment intensities. Two studies were carried out in this thesis. In the first study the storage longevity of seeds treated with aerated steam was examined. The second study investigated the shelf-life of the pre-tests used to determine the aerated steam treatment tolerance of a seed lot, by testing the treatment tolerance of seeds aged prior to the treatment.

In this study bone material from six stone ship settings and a total of seven deposits of bones from two sites on the island of Gotland have been analyzed. Four ship settings from the burial site at Gålrum in Alskog parish and two from Tängelgårda in Lärbro parish. The ships contained both cremated remains and inhumations.  Human remains were identified in five of the analyzed ship settings and a minimum of six individuals was identified in total.  Animals were found in three of the ship settings, where one of them contained only the burned remains of a dog. Two of the ships contained inhumations, one in Gålrum and one in Tängelgårda.

This paper deals with diet and gender in the early roman iron age in Sweden. Human bone and tooth material from the Iron Age cemetery at Bjärby in Kastlösa parish on the island of Öland have been analysed for stable carbon and nitrogen isotopes. 21 individuals were sampled. Where possible 4 samples were taken from each individual, from the first, second and third molar respectively and from one compact bone. By doing so it is possible, at least in theory, to trace intra-individual diets throughout life.

There is convincing research which shows that the enzyme alkaline phosphatase (ALP) has a central role in the mineralization of bone, more precisely that its catalytic activity is needed in the process. ALP is found on the surface of matrix vesicles where the mineral is formed. One theory about the function of the enzyme is that it binds to fibrous collagen in the bone and thereby incorporating the mineral into the bone. The purpose of this study is to establish whether ALP binds to collagen. If this is the case, more elaborate studies around this will be performed.

This thesis presents the results from a osteological analysis and a GIS-study aimed to examinedifferences in the located animal bones in different areas of the excavation site of Ajvde.The osteological material came from five excavated square meters on the site and was comparedwith osteological results from other researchers from different areas to create overview and try tosee differences between the areas.The GIS-study took data from all animal bone material excavated on the site, a total of about 2300kilos, and presented them in maps of spatial distribution for each layer (pictures 4, 5, 6 & appendixpicture 1) to see if there were any clusters of activity and changes between the layers. The dating ofthe culture layer and the burial field (pictures 7 & 8) were presented in maps to see if they could becorrelated with what was seen with the animal bones. Pictures of different shorelines were alsopresented (picture 9) to compare with the results that were seen in the changes of animal bones fromdifferent layers.The results of the GIS-study have shown that the activity on the site have moved over time alongthe hight differences of the land. The earlier layers show activity only on the higher elevation butlater moves down, and in the upper layers activity have been all over the excavated area. Clusters ofanimal bones were seen in the so called ?black areas? of the sites (shown in picture 2) but also otherareas contained a lot of animal bones.The results of the osteological analysis have shown that there are differences in what species arefound in different areas.

SAMMANFATTNING Artros och skador i ledbrosk är vanliga problem hos både människor och djur, som orsakar stora fysiska besvär i form av smärta och nedsatt rörelseförmåga. Idag finns ett flertal olika behandlingsmetoder mot artros, men ännu finns ingen bra behandlingsmetod för att åstadkomma läkning av ett skadat ledbrosk. I den här studien användes kanin som modelldjur för att utvärdera en ny behandling mot artros på människa. Målet var att stimulera nybildning av ledbrosk via rekrytering av mesenkymala stamceller. Studien utfördes på 20 kaniner av rasen New Zeeland White, 6-7 månader gamla honor med en kroppsvikt på ca 4 kg. En ledskada skapades med borr på den mediala femurkondylen i kaninernas vänstra knäled under anestesi. Därefter injicerades en hyaluronsyragel enbart eller tillsammans med tillväxtfaktorn bone morphogenic protein-2 (BMP-2) i leden.

Muskuloskeletala skador är ett stort problem hos hästar som tränas och tävlas i kapplöpning, och orsakar smärta med påföljande hälta för individen och ger även ekonomiska förluster inom industrin. Av dessa är stressfrakturer i tredje metakarpalbenet distalt på frambenet vanligast och utgången är ofta katastrofal med avslut på karriären och i vissa fall slakt. För denna typ av skada finns alltid en preexisterande patologi i benvävnaden. Träningen är högintensiv och kräver en fysisk adaptation av rörelseapparaten. Den kraftiga mekaniska belastningen kan kopplas till predilektionsplatser för frakturerna, där mikroskador i benvävnad utvecklas till fullständiga frakturer.

This paper deals with stable isotope analysis on the children of the early Christian cemetery in Varnhem, Västergötland. Human bone and tooth material from the cemetery has been analysed for stable carbon, nitrogen and sulphur isotopes. The analysis showed that the diet had been homogeneous and that the children had been breastfed, with a possible exception of the child from grave 100..

Background: Testosterone is the most important androgenic hormone in the male. Aging is closely associated with reduction of serum testosterone which can lead to reduced muscle mass, muscle strength, bone density, and depression. These symptoms may be counteracted by administration of testosterone. Objective: The purpose of this study was to examine the effects of hormone replacement in men with age-related testosterone deficiency. Method: We performed a systematic review using Randomised Controlled Trials (RCT).

Are agency and responsibility solely ascribable to humans? The advent of artificial intelligence (AI), including the development of so-called ?affective computing,? appears to be chipping away at the traditional building blocks of moral agency and responsibility. Spurred by the realization that fully autonomous, self-aware, even rational and emotionally-intelligent computer systems may emerge in the future, professionals in engineering and computer science have historically been the most vocal to warn of the ways in which such systems may alter our understanding of computer ethics. Despite the increasing attention of many philosophers and ethicists to the development of AI, there continues to exist a fair amount of conceptual muddiness on the conditions for assigning agency and responsibility to such systems, from both an ethical and a legal perspective. Moral and legal philosophies may overlap to a high degree, but are neither interchangeable nor identical.

When creating a good lighting design it is crucial to know how different types of lamps work. Knowing what kind of light they emit and in which situations they work well is also very important. In this master thesis I present different types of lamps and give an account of how light is spread through the different shapes of luminaires, reflectors, filters and so on. I write about how our eyes register radiation and connections between lighting and how it makes us experience space. Furthermore I deal with the effect of artificial light on living organisms and the environment. After the theoretical studies I deal with the places I have visited to study how different lamps and luminaires work and look like in existing lighting designs. These visits have also been inspirational to my lighting proposal for Bokenäs. Bokenäs is Volvo?s resort and conference center which is situated on the Swedish west coast.
