Inomhusmiljöproblem i fuktiga byggnader : En utredning av åtgärder vid fuktrelaterade inomhusmiljöproblem

Dampness in the indoor environment have been a major issue of discussion the last decades since more and more people complain about their indoor environment. In the present situation there are difficulties to find what causes people?s discomfort in a damp environment even though there is a strong connection between dampness and human health.The aim of the thesis was to contribute to the work done today to achieve a better indoor environment in damp buildings. The purpose of the work was to evaluate whether the measures issued for dampness in the indoor environment contributes to the improvement of health and environment for those who are living or working in that space. Through a literature review, interview and survey the following three questions were answered to achieve the aim and purpose:How are people affected by the indoor environment in damp buildings?Which are the measures issued to prevent dampness in the indoor environment?Do these interventions contribute to a better indoor environment?How people are affected by the indoor environment in damp buildings and how these problems are prevented were the foundation for the continued work with the survey.

Hormonell påverkan och receptoruttryck i juvertumörer hos hund

Juvertumörer är de vanligaste tumörerna hos tikar och det finns olika typer av både benigna och maligna juvertumörer. De hormonella fluktuationerna som sker under östralcykeln driver utvecklingen av juvervävnaden och behandling med progestiner (syntetiska ekvivalenter till progesteron) för uppskjutande av löp har kopplats samman med förekomst av juvertumörer, vilket har lett till ett intresse för den hormonella påverkan på juvertumörutvecklingen. Hormonerna är i sin tur beroende av uttrycket av receptorer för att kunna ha effekt i vävnaden. Syftet med den här litteraturstudien är att utreda uttrycket av hormoner och receptorer för progesteron, tillväxthormon (growth hormone, GH) och insulinliknande tillväxtfaktor (insulin-like growth factor, IGF) i normal juvervävnad och i benigna och maligna tumörer, såväl som deras påverkan på juvertumörutvecklingen. De intracellulära signalvägarna för progesteronreceptorer (PR), GH-receptorer (GHR) och IGF-I-receptorn (IGF-IR) är kopplade till cellproliferation och genreglering. De komplexa nätverken av signalvägar interagerar med varandra och en obalans i uttryck och reglering av hormoner, receptorer eller molekyler i cellen kan leda till att tumörer uppstår. Vid progestinbehandling har ökade nivåer av GH och IGF-I uppmätts och högst nivåer sågs i maligna tumörer.

Höggallring i praktiskt skogsbruk : beskrivning av en gallringsmodell för granskog som tillämpas på Trolleholms Gods

When Norway spruce is planted with large initial spacing and grows on highly productive sites in southern Sweden, a high proportion of the stems gets broad annual rings. The thinning programme carried out at the estate of Trolleholm aims to extract stems with too broad ring width. The 3-4 first thinnings are carried out as thinning from above, where only the thickest trees are removed. The internal distance may not fall below 5-7 meters depending on the number of thinning (short distance in young stands). The aim of this study was to examine the thinning model that is carried out at the estate of Trolleholm. A volume table is calculated to describe the model, and data is collected on temporary plots.

Tillväxthinder i små byggföretag : Och hur dessa kan undvikas genom anpassad styrning

Bakgrund: Idag har det blivit allt viktigare att företag växer, då det skapar förutsättningar att utveckla samhället genom att exempelvis skapa fler nya jobb. I de små företagen finns stor tillväxtpotential och tillväxtvilja, men det är svårt att undkomma olika tillväxthinder och växa lönsamt. Många små företag består av byggföretag och det är vanligt att små byggföretag lyckas växa snabbt, men många av dem går ändå i konkurs. Frågan är hur en anpassad styrning av företagens organisation kan bidra till att underlätta tillväxten och hjälpa företagen att lösa de organisatoriska styrningsproblem som kan uppstå.Syfte: Vårt syfte med studien är att undersöka vilka styrningsproblem som vanligtvis uppstår vid tillväxt av små byggföretag och hur dessa problem påverkar den fortsatta tillväxten, samt ta reda på hur styrningsproblemen kan lösas med en, för branschen, anpassad styrning.Definitioner: Tillväxt betyder vanligtvis att något växer eller ökar i mängd. Tillväxt kan även innebära att något ökar i storlek eller att kvalitén förbättras till följd av en processutveckling.

Lämplig röjningstidpunkt utifrån björkstubbskottens konkurrens

The purpose of this report was to investigate if there are any correlation between spruce medium height in young spruce stands and the number of birch stump shoots. The purpose was also to investigate if there are any correlation between the spruce height growth after clearing and the mean height of birch stump shoots. The reason for this investigation is that the problem with birch stump shoots after clearing can be expensive if there must be additional clearings before the first thinning. The study provides no apparent association and therefore no special clearance height is recommended. In the final stages of the work there are given some comments on the study´s weaknesses. Finally topics for further research are suggested..

EU om olagligt och skadligt innehåll på Internet. En diskursteoretisk analys

This thesis analyses how the European Unions institutions deal with the issue of illegal and harmful content on the Internet in key documents presented during the period 19961999. Particular attention is attached to content where the legal status is determined in relation to the user and to content that is legal, but characterized as harmful and entailing a need for special protective measures. The theoretical and methodological approach draws on discourse theory as formulated by Laclau and Mouffe. The thesis studies how the problem is represented in key documents from the European Commission, the Council of the European Union, the European Parliament, the Economic and Social Committee and the Committee of the Regions, with particular regard to the discourse on harmfulness, the child and Europe. The findings are that the overall discourse has shifted focus over time, from an emphasis on the protection of minors toward a more market-oriented discourse stressing the importance of protecting the competitiveness of the European economy.

En tesaurus som ledsagare ? En jämförande studie av tre sökstrategiers inverkan på återvinningsresultatet i en bibliografisk databas.

This Master?s thesis is a comparative study of information retrieval results between three distinct search strategies in simulated automatic query expansion in a bibliographic database. Our purpose is to investigate which of the search strategies score the most effective precision and to what extent the same relevant documents are retrieved (overlapped). A thesaurus attached to the database is used to select appropriate descriptors for the baseline query formulations which subsequently are expanded with hierarchical relations. The search strategies are s1: A baseline query with two or three descriptors, s2: The baseline descriptors combined with at least one Narrower Term, s3: The baseline descriptors combined with Narrower Term and at least one Broader Term.

Den ledande kvinnan : En studie av ledarskapsbeteenden i fyra olika branscher

The debate about women and equality is a very burning issue in the Swedish society today. There are a lot of articles, TV-programs, books and web sites treating the position of female leaders today. There are also a lot of myths strongly attached to our minds hindering the equalization process between men and women.The main purpose of our study was to look at women as leaders and identify potential tendencies in businesses sectors dominated by mainly men or women. We also wanted to find out whether leadership behavior is more or less oriented towards relations- or task in any of the chosen sectors. It was even in our interest to see if our chosen respondents supported the myths in our society about male and female qualities.We interviewed 20 women in four different sectors, two dominated by men (Computer/It, Transport) and two dominated by women (School, Healthcare).

Strategi och struktur i småbarns byggprocess : Vilka erfarenheter har småbarn av byggklossars form och balans?

I dagens samhälle har många kundföretag problem med datalagringen vilket beror på att behovet av att lagra data började öka kraftigt under 2000-talet och har fortsatt öka sedan dess. När kundföretagen började använda sig av virtualisering så expanderade även datastorleken. I samband med att datastorleken växte ville företagen att data inte skulle lagras lokalt utan att den skulle vara lagrad på en central plats som en serverhall och vara överskådlig.Studien utfördes på tre sätt, först undersöktes vilka datalagringslösningar som fanns och det skedde genom litteraturstudier. Därefter kontaktades företag som använde olika lösningar för datalagring. Nästa steg var att kontakta de leverantörer som kundföretag använde sig av och som levererade lösningarna.Under arbetets gång upptäcktes olika lösningar på problematiken med ett ökat datalagringsbehov.

Magnetfält alstrade kring nätstationer i samband med lokaldistribution av elkraft : Magnetic fields generated by electrical substations during distribution of electric power

Abstract: This report covers primarily the work of documenting electromagnetic fields generated by one of the later parts in the electrical power distribution chain: The electrical substation, wherein 10 kV is transformed to 400 V for use by private consumers. Thus it is one of the most widespread and frequently occurring parts in the Swedish power grid and of particular interest, as electrical substations are found everywhere in populated areas, often in close vicinity to people and animals.The report deals with a number of formulated questions and/or hypothesis? stated at the onset of the work undertaken, theory that is relevant for the topics the report covers, the details of the field work undertaken and the following analysis of the readings, which in term provide answers for the questions stated in the beginning. It also covers what is the currently known short term and long term risks associated with electromagnetic fields in the power frequent spectrum and of varying intensity in the vicinity of humans.The analysis also provides recommendations and identifies several points to carefully consider when planning for new installations or replacements of some parts of existing installations.For enhanced reading comprehension there is, aside from sections with pictures and attached explanatory texts and templates, several graphs, one-line diagram and maps of the power grid among the appendixes to the rapport..
