Gotland is an island in the Baltic Sea where man has introduced roe deer. The last successful reintroduction was in the 1980s and is the base of the viable roe deer population of today.The aim of this study was to estimate the roe deer population density in 2012 and the species population dynamic since the time when studies on the population started. The result indicates a population size of 850 roe deer in 2012. There was no significant population dynamic, which may be due to insufficient data. The population occurs basically over the whole island but have not yet been established in all suitable areas.

The purpose of this master thesis is to evaluate how internal vehicle information inScania buses and trucks can be used for evaluation of driver performance regardingfuel economy, vehicle wear, traffic safety, emissions and cargo damage. To someextent it was examined whether this information could be used for training the driverto a better driving style. In addition, a prototype for such a system was developed.By first defining what distinguishes a talented driver and how he/she differs from apoor driver, followed by a study of the internal vehicle communication, a system thatin real-time gathers and interprets vehicle data could be developed.The resulting system can with reasonably high reliability detect a number of trafficevents (such as braking, lane changing or hilltops). At each such event, the driver?sbehaviour can be evaluated.

Syftet med denna studie är att få ökad kunskap om vilka olika lösningstrategier elever i år 3 tillämpar när de löser ett matematiskt problem. Har eleverna utvecklingsbara strategier? Finns det elever som väljer strategier som ej är utvecklingsbara?Vi valde att använda oss av en kvalitativ undersökning där vi tolkade elevernas lösningar av två matematiska problem av varierande svårighetsgrad. Utifrån denna tolkning kunde vi dela upp lösningarna i olika lösningsstrategier som eleverna använde sig av. Undersökningen genomfördes på 89 elever på tre skolor i olika kommuner.

Syftet med denna studie är att synliggöra några elevers svårigheter när det gäller de centrala aspekterna i grundläggande taluppfattning, med fokus på addition och subtraktion. Studien grundar sig på 13 intervjuer med elever i årskurs 3-5. Som utgångsmaterial för intervjuerna användes den muntliga diagnosen Individuella samtal som ingår i Diagnostiska uppgifter i matematik för användning i de tidiga skolåren (Skolverket, 2010c). I samband med intervjuerna observerades även hur eleverna konkretiserar uppgifterna med stöd av sina fingrar och tiobasmaterial. Den muntliga diagnosen ger en tydlig bild av vilka strategier eleverna använder sig av när de löser en uppgift samt visar vilka svårigheter eleverna har när det gäller grundläggande taluppfattning.Studiens resultat visar att eleverna har svårigheter med den grundläggande taluppfattningen, dock i varierande grad.

The word mathematics is often associated to addition, subtraction, division or multiplication. This is not the kind of mathematics that belongs to pre-school. In my essay I have chosen to write about how mathematics is used in pre-school. In the literature it is written that the best way of becoming familiar with mathematics, is to integrate it in the every day life but that there are educators that use traditional mathematics education in pre-school. The questions I would like to answer are:1.

The Swedish ostrich production started about thirteen years ago and still there are no Swedish recommendations regarding ostriches? space requirements. The European Council give recommendations and the Swedish Board of Agriculture (SJV) has a proposal, but so far the producers follow Danish regulations regarding space requirements. The Swedish Animal Welfare Agency are about to set standards for the ostriches? space requirements, and therefore the Swedish ostrich producers, together with The Federation of Swedish Farmers (LRF) ask for a scientific background to these decisions. This thesis is a preliminary study at the prospect of a future experiment on which factors important for ostriches? space requirements and welfare will be examined more thouroughly.

One of the biggest challenges in the human history is to prevent environmental pollution. Everybody has an indirect or direct influence on the environment through his or her consumption. The stakeholders are not just interested in price and quality, they are also interested in the circumstances of production and how this affects the environment. By taking environmental concern in public procurement it is possible to speed up the environmental adjustment of services and products. Environmental awareness has become more and more self evident in the environmental work.

The theoretical background in this essay made clear that the students? knowledge about physics improve, and they express a more positive attitude towards physics as a subject, when they have access to a more laboratory-based learning style. The aim of this study is to research how the placement of the lab relative to the lecture affects the students? experiences and level of knowledge. The study involved students in year eight and was carried out during four weeks.

Denna rapport är en jämförande studie av utvalda konsolidanter som används till att stabilisera nedbrutet insektsangripet trä. Av de trägnagande skadeinsekter vi har i Sverige är det främst den strimmiga trägnagaren som är intressant i möbelsammanhang. I rapporten beskrivs den strimmiga trägnagaren, en liten skadeinsekt som kan åstadkomma stor skada om den får verka ostörd. Insekten finns utspridd i hela Europa och är ett stort problem då den angriper alla typer av träslag. Nedbrutet insektsangripet trä förlorar sin styrka och kan behöva konsolideras genom att injicera konsolidanter in i träet.

Destillers dried grains with soluble (DDGS) is a by-product when producing ethanol. DDGS from wheat has a high crude protein content and a good amino acid profile, which makes it an interesting feed ingredient for poultry. The disadvantage of feeding DDGS from wheat to poultry is that it also contains a high fiber content that chickens don?t have the ability to break down. Lantmännen Agroetanol has developed a new protein feedstuff from DDGS by extracting wheat protein from DDGS, the product name is Agroprotein SD.

SammanfattningSyfte och frågeställningar Syftet med denna uppsats var att undersöka hurvida en LCHF (Low Carb High Fat) kost skulle kunna vara en hälsosam livsstil utifrån hur den påverkar olika hälsomarkörer hos normalviktiga personer där en viktminskning ej har eftersträvats. Frågeställningen var följande: Hur påverkar en LCHF-kost med maximalt 30 gram kolhydrater per dag under 3 veckor normalviktiga kvinnors BMR (Basal Metabolic Rate), blodlipider, blodglukos, blodtryck, kroppssammansättning, midje- och höftmått samt deras kroppsvikt?Metod En experimentell studie har genomförts på 8 normalviktiga kvinnor mellan 20 och 35 år. Samtliga försökspersoners BMR, blodlipider, blodglukos, blodtryck, kroppssammansättning, midje- och höftmått samt kroppsvikt mättes vid normala levnadsförhållanden innan studiens start samt efter 3 veckor av en strikt LCHF-kost med endast 30 gram kolhydrater per dag.Resultat BMR sänktes i genomsnitt med 4,4% vilket var signifikant (P<0,05). HDL (High-density lipoproteins), LDL (Low-density lipoproteins) samt totalkolesterol höjdes signifikant (P<0,01) med 21%, 25% respektive 22%.

The rainforests of the world are important not only to the countries in which they grow but to the world as a whole. They influence oxygen and water circulation as well as carbon sequestration which in turn affect global radiation and global warming. The forest also have great value and in Malaysia as in many other tropical countries large volumes are harvested which leaves great areas of degraded forest with little growth and biological diversity. Due to their low financial value these forests are often transformed and used for other purposes than forestry such as oil palm plantations. The trees are often transported out of the forest using large bulldozers. They are heavy which causes compaction of the forest floor and during transport the top soil layers are moved to improve mobility.

Headwater streams are affected by anthropogenic impacts at multiple scales. One aspect of human impact is sediment transport associated to the abundance of stream structures as large woody debris and the composition of the riparian zone from forest to agricultural landscapes. Riparian buffer zones and stream structures like dead wood are considered as generally important structures for protection against an increasing amount of sediment particles in the water. Hence, in this study these structures were quantified in thirty different stream segments on land and in the water. To measure the transport of sediment Whitlock-Vibert boxes were used in three different types of landscapes; forest, transition and fields. The boxes were left in the stream segments for three months, the taken up and dried and weighed. The results showed that the transition-land in Frösvidalsån had the highest sediment transport. The second highest transport of sediment was in Blackstaån at the fields.
