Projekt Sunbaker : Utveckling av en solugn för bakning, en fältstudie i Namibia

Namibia, southern Africa, suffers from an energy shortage and is therefore facing severalchallenging problems. The use of firewood as fuel for cooking is common in the whole countryand has negative consequences for health and the environment. This work have focused ondeveloping a solar baking oven, calledSunbaker, adapted for Namibian families needs forbaking. The development was based on classic solar cooking limitations, specific needs forNamibia and to have a feasible manufacturability.The project started with a theoretical study in Sweden where different solar cookers, informationregarding Namibia, technical aspects and end user aspects were studied. To assess the need for asolar baking oven aMinor Field Study took place in Namibia during eight weeks in July toSeptember 2009 and resulted in a product design specification.

Giraffens blodtrycksreglering

Through previous studies during my education, I have experienced that chemical deicing road salt is a known problem, mainly in southern Sweden. Road salt causes damage to the environment and also damage to vehicles and structures such as bridges, etc. Road salt causes vehicles and steel constructions to rust, leading to increased costs for repairs of damage to structures. Road salt also causes damage to the plants and the economy to suffer, when plant material and soil needs to be replaced. In order to get closer to a solution, I put up three questions.

Fröodling av Raj- och rörsvingel i Sverige

Festulolium (Festulolium) and tall fescue (Festuca arundinacea) has not been grown inSweden over a longer period. So far there is no greater area cultivated, but the area isincreasing. Festulolium and tall fescue are expected to eventually replace meadowfescue in many leyseed mixtures to dairy cows in southern and central Sweden. Tallfescue has in recent years become popular again. Festulolium is a hybrid betweenryegrass and fescue.

Det är mycket viktigt att förhindra att bekämpningsmedelsubstanser läcker ut i miljön och orsakar skada. Lagstiftningen kräver därför att läckaget av bekämpningsmedel från odlad mark minskas. Olika myndigheter och organisationer har olika ansvarsområden beträffande bekämpningsmedel. Bekämpningsmedelssubstanser kan, om de inte hanteras rätt, vara skadliga och därför finns det tydliga bestämmelser om hur dessa substanser ska hanteras. Många oberoende undersökningar visar tydligt på att det förekommer läckage av bekämpningsmedel i samband med att de används i behandlingar av odlad mark. Undersökningar har pågått under lång tid både i Sverige och i andra länder. Ett flertal åtgärder och metoder mot läckage av bekämpningsmedel från odlad mark har framtagits och utvecklats som radikalt kan minska läckaget av bekämpningsmedel.

Studenters inställning till fysisk aktivitet på recept - Ger yrkesutbildningen förutsättningar för studenterna att arbeta med metoden?

Det är vetenskapligt underbyggt att det finns ett tydligt samband mellan omfattning av fysisk aktivitet och hälsotillstånd. Genom att öka den fysiska aktiviteten går det att komma åt en av de stora grundorsakerna till vällevnadssjukdomar, fysisk inaktivitet. Fysisk aktivitet på recept (FaR) är en metod i ett steg mot en mer hälsofrämjande hälso- och sjukvård och för att etablera en långsiktig förändring av samhällets syn på fysisk aktivitet. Utvärderingar visar såhär långt att mer motivation och kunskap krävs hos vårdpersonalen för att arbeta efter FaR-metoden. Syftet är att undersöka attityden till FaR bland sista-termins studenter på läkar-, sjuksköterske-, sjukgymnast- och arbetsterapeut- utbildningen, samt om utbildningarna gett förutsättningar att kunna arbeta med metoden i framtiden.

Majsensilage - partikelstorleksfördelning och hygienisk kvalité :

Fieldstudys on 22 farms (23 silos) to study relationships between the actual particle size of the maize silage and the theoretical length of cut. The measure of theoretical length of cut were stated by the farmers and not measured by us. Particle size of maize silage was determined using the New Penn State Forage Particle Separator. SLU Skara made a special sieve for us, that had larger holes than de original sieves. The samples were shaken after instructions and then the material was weighted. We have also been taking out samples for microbiological analyses from the silos on 13 of the farms.

Större svartbagge Upis ceramboides i norra Hälsingland : förekomst, substratkrav och effekter av skogsbrukets naturvårdsåtgärder

Many wood living insects are considered threatened by modern forestry due to the reduction in amount of dead wood. During the last decade various methods have been used to enhance the quantity of dead wood in managed forests. However little is known how and if these methods are aiding saproxylic insects. The threatened tenebrionid beetle, Upis ceramboides, is already extinct in southern Sweden. It develops in white rotted dead birch (Betula spp) and requires sun-exposed sites.

Modellering och styrning av flis till en sulfatkokare

At the Skoghall pappermill, sulphatepaper pulp is produced in a continuous digester originally from 1969. To be able to maintain a high level of production there is a need for a process with few disturbances. Variations in how well the wooden chips are packed in the digester is one form of disturbance. Today there are no available measurements on how well the chips are packed. Instead this is regarded as being constant.

Lokal etisk produktion ? är den globalt hållbar?

In modern society globalisation is a fact within all industries, the textile industry included. Due to improvement in areas such as logistics and communication international trade have developed fast. As changes occur rapidly on the global market and companies must adjust and revise their processes in order to stay competitive.Because of the global price reduction consumers around the world expect low-price products, which mean that the companies have to find new ways to produce in a cost-efficient way. To maximize profit most of the textile production is situated in low-cost countries due to its labour-intensive character. It is crucial for fashion companies to allocate their activities in their value-chain effectively in order to reduce lead-times.

Användande av avskjutningsstatistik i förvaltning : påverkar tidigare jakt CPUE?

In fisheries, there is a long tradition to use catch data when evaluating changes in the stock and effects from harvesting. It is a common practice to use Catch Per Unit Effort (CPUE) as an index of population size, and several studies have investigated the properties of CPUE in relation to population abundance, spatial distribution and efficiency of gear. In research, catch rate on trap-transects is used as an index of abundance for wildlife species but CPUE is rarely applied as a tool in harvest management.In 1993, more than 60 000 km2 of the state managed mountain range in Sweden was opened to the public for small game hunting, under the responsibility of the county administrative boards in Jämtland, Västerbotten and Norrbotten. The total area is now divided into 332 hunting units (median=73 km2) and an internet based system is used to administer licences and reporting bag statistic. Each hunter has to register the results within two weeks after the hunt.

Alnarps rehabiliteringsskog : ett gestalningsförslag

The understanding of the role of nature for rehabilitation of both physical and psychological afflictions has greatly increased in the last few years. There?s a lot of science that describes the healing effects of nature. The rehabilitation garden in Alnarp has contributed with very positive results from the treatments of patients with burnout syndrome. In the first stages of rehabilitation, the need for calm is very important and a demand-less and stress-free environment is of essence.

Igenväxning av Köphultasjö : bakomliggande orsaker och processer

Köphultasjön är en sjö som ligger inom Lagans dräneringsområde mellan SkånesFagerhult och Markaryd. Köphultasjö och dess närområde har under årens lopp utsatts avolika typer av påverkan, både naturlig och antropogen.Detta examensarbete undersöker och analyserar orsaker till Köphultasjöns igenväxning.Vidare beskrivs processer, som antas påverka igenväxningen av Köphultasjö, med hjälpav en igenväxningsmodell.De främsta indikatorerna på igenväxning av en sjö är gungfly och vass. Förekomsten avgungfly och vass pekar på både naturlig och antropogen igenväxning av Köphultasjö.Naturlig och antropogen igenväxningen av sjön har bekräftats med egna observationer ifält. Den naturliga igenväxningen motsvaras av den gungflyartade vegetationen, som harringa utbredning. Den nutida utbredningen av igenväxning består till en större del av vassän av gungfly.

Är bor nödvändigt vid skogsgödsling i Sverige?

This thesis has been made on behalf of SCA Skog AB to assess the need of boron in Swedishforest fertilization. Boron has been added to Swedish forest fertilizers since the beginning of the1980s. This makes the fertilizers more expensive and therefore has the necessity of boron inSwedish forest fertilization been raised.The Swedish bedrock generally contains small amounts of boron. The boron in the bedrock istightly bound to the mineral tourmaline and mostly unavailable for plants. This leads to that thecontribution of boron to the soil from weathering is very low besides soils with marinesediments.
