En rättvisande bild av biblioteken? Problem och möjligheter kring folkbibliotekens verksamhetsberättelser

The purpose of this master´s thesis was to investigate the role and function of the annual reports of public libraries: for what purpose are they put together and how are they evaluated and utilised. The study presents different views on the structure and content of library annual reports. Focusing on a specific public library and its municipal administration, the authors identify and describe problems and possibilities regarding the library annual reports. The study also provides a general view of their occurrence, their addressees and the importance attached to them.In a review of current literature on accounting and activity reports the authors place the annual reports of public libraries in a wider context. The study also presents two current models of performance measurement - the Intangible Assets Monitor and the Balanced Scorecard - which were developed in the private sector, and the authors discuss their relevance when applied to public libraries.Data were collected both in interviews and by means of a questionnaire.

Nedbrytning av propylenglykol i uppsamlingssystem för avisningsvätskor : En studie utförd vid Stockholm Arlanda flygplats

Deicing fluids based on Propylene glycol are used at Stockholm Arlanda airport to remove or prevent ice on aircrafts. The high oxygen demand of propylene glycol can cause oxygen depletion in rivers downstream from the airport if not collected. Mass balance calculations made by Swedavia indicate that the actual amount of gathered propylene glycol is underestimated. Suspicions that propylene glycol is degraded in the stormwatersystem designed to collect deicingfluids, called the B-glycolsystem, have to be investigated in order to establish with certainty that no propylene glycol in other ways leaves the B-glycol system.The purpose of this study was to determine if degradation of propylene glycol is present in the B-glycol system and also to estimate the extent of the degradation. Propylene glycols high biological oxygen demand can cause oxygen depletion in waters downstream from Stockholm Arlanda airport if not collected.

Habitat preference and dispersal of a sandassociated beetle, Apalus bimaculatus

Species that have a high degree of specialization and poor dispersal ability can be more prone to extinction than more generalist species and good dispersers. How these species traits affect the viability of populations is dependent on landscape factors,such as isolation and connectivity. Additionally, interactions between species (e.g. symbiosis), and how these interactions vary spatially and temporally can have a large impact on populations. When the range and habitat areas of a species continuously decrease, management strategies are often needed if the species shall be able to survive.

Utvärdering av statistiska analysmetoder för detektion av partiell nedisning av anemometrar

Detaljerad information om vindförhållandena på en site är en nödvändighet för att göra beräkningar av lönsamhet i ett vindkraftsprojekt. Mätningarna behöver vara kontinuerliga och så korrekta som möjligt. Därtill bör de göras under minst ett års tid eftersom vindförhållandena på en plats är säsongsberoende. Under vintertid och framför allt på högre latituder eller altituder, kan mätutrustning påverkas av nedisning. En nedisad anemometer kan ge databortfall eller felaktiga mätningar.Identifiering av felaktiga data är en viktig del av analyseringsarbetet eftersom risken annars är att vindförhållandena på platsen underskattas.

PlusTak

Today´s roofing of dwelling houses is a very time consuming procedure, which includes a lot of different steps on the construction site. Not only does it cost a lot of money, but often do problems with rot and mold occur in the attics of houses today. The use of prefabricated modules has seen a great breakthrough in the field of construction of dwelling houses; at least when it comes to foundations and walls, where this type of approach makes the construction process way more efficient. What no one previous has succeeded to develop is a corresponding system for roofs that meets the demands of a dwelling house. Accordingly the goal of PlusTak has been to come up with a proper module system for roofing of dwelling houses, where the roofing is completed to meet the demands of the Scandinavian market. During the project a lot of effort has been put into customer contacts and the usability of the product, as well in the manufacturing process as on the construction site. This development has gone hand in hand with several practical tests and tryouts.

Timeliness cost for agricultural sprayers : weed control in cereal crops

Evaluation of machinery costs is necessary for selecting appropriate farm machinery. Timeliness cost due to untimely operations is an important component of machinery costs. Timeliness costs can be high for crop sprayers, since pesticide application must be carried out within a short time interval. This Master thesis investigated the timeliness cost and the probability of a suitable workday for spraying. Timeliness factors were estimated for four different crops (oats, spring wheat, winter wheat and barley) using historical weed trial data.

Hur påverkas dvärghamstrar av att vistas i hamsterbollar?

Lately the popularity to keep different species of dwarf hamsters has increased in Sweden. The requirements of the Swedish legislation to keep hamsters as pets are low which could be a reason for the increasing popularity. Hamsters are in nature generally nocturnal and can travel far distances to find food sources during their active part of the day. Their eyesight is poor, but is compensated by their well-developed hearing and olfaction. ?Run about balls? are made of plastic and the hamster is placed inside it where after the ball is placed on the floor and the hamster can then run protected outside the cage.

Energieffektivisering av aerbo reningsprocess : Tillsats av biprodukter i skogsindustriellt avloppsvatten

In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.

Will Love Tear Us Apart? : En studie av inträdesprocessen till goth-kulturen

Inledning Wallenbergare var från början en elegant restaurangmaträtt bestående av en panerad kalvfärsbiff serverad med potatispuré, ärtor, lingon och skirat smör. Rätten torde vara uppkallad efter häradshövdingen Marcus Wallenberg någon gång under 1930- talet. Det finns många historier om Wallenbergarens uppkomst men ingen tycks veta med säkerhet vem som serverade den för alldra första gången.Syfte Syftet med denna uppsats var att undersöka hur val av styckningsdetalj, kryddning, temperatur och mixning påverkar den sensoriska kvaliteten i en Wallenbergare.Metod/material De tre metoder som användes under denna studie var en provmatlagning med en större mängd av variabler, en enkätundersökning gällande tidigare erfarenheter och uppfattningar om Wallenbergare samt en sensorisk bedömning av biffens sensoriska kvalitet.Resultat För att Wallenbergaren ska uppnå en konsistens av hög sensorisk kvalitet bör denna bestå av 75 % malt kalvinnanlår, 25 % kalvbräss, äggula, grädde och salt. En Wallenbergare bör endast smaksättas med salt och nymald vitpeppar.Provernas samtliga ingredienser skall vara väl kylda för att uppnå högsta sensoriska kvalitet. De prover som blandades med handkraft erhöll en lägre sensorisk kvalitet än de prover som blandades mekaniskt.

Productivity of Norway spruce (Picea abies) and Scots pine (Pinus sylvestris) in coastal areas of northern Sweden

Productivity of Norway spruce (Picea abies) and Scots pine (Pinus sylvestris) was studied on 12 sites in coastal areas of northern Sweden. On each site, sample plots were placed in adjacent Norway spruce and Scots pine stands with similar ages in between. Basal area, tree height, Site Index, volume production, simulated maximum mean annual increment (MAImax) and tree vitality were compared for the two species. Average basal area at the time of measurement was 30.4% larger for Scots pine stands than for Norway spruce stands. The difference between the two species in basal area increment during the last 10 years was related to stand age.

Inhysning av struts :

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.

Det krympande klassrummet : En studie av högstadielärares förutsättningar i ett reformerat skolsystem

Since the 1990?s the Swedish school system has undergone major and recurring structural reforms. Two of the most comprehensive changes has been the shift of primary schools as an integral part of the welfare state to the responsibility of the municipalities as well as the introduction of free school choice for the students. Through two months of participant observations and semi-structured interviews this thesis seeks to answer the question of how these reforms has come to effect the work of teachers in a medium sized public school in a small municipality in the outskirts of Stockholm. Earlier research has shown that public schools in socio-economically vulnerable areas are disadvantaged due to the reformation of the school system (Beach & Sernhede, 2011; Östh, Andersson, & Malmberg, 2013).
