Översvämningsmodellering av ett dagvattensystem

Storm water management has become a more important matter as urban areas are expanding and natural areas are being exploited. As nature landscapes are being converted into hard surface areas storm water flow is affected both in terms of velocity and size. A flow increase can easily result in a flooding if the dimensions of the pipeline system are inadequate. Considering predicted upcoming climate changes, flooding?s may become more common in urban areas in the future.

Career choice:The relationship between personality, state anxiety and the career decidedness among Swedish upper secondary school students

The main purpose of this study was to inquire into personality and the state anxiety in relation to career decidedness scale among students in upper secondary school. The participants were 124 students in three grades and respectively non vocationally oriented classes. The participants were asked to grade themselves on a scale in relation to the statements regarding, state of decidedness for career choice, personality (NEO FFI, Costa & McCrae, 1985. Sweden, Gerontologic Center) and anxiety (AnTI, Wells, 1994). The results showed no significant relationship between personality and state of anxiety that could be connected to the decidedness for career choice.

Fällning av kisel från avloppsvatten vid Hellisheidarvirkjun - experimentell studie

This report is about the experiments with mixing of the separated water and the vacuum pump seal water at Hellisheiði power plant. This is done to prevent silica scaling and clogging in pipes and reinjection Wells as well as eliminating vacuum pump seal water from the plant. The experiments were done in four stages: the first stage comprised of tests with different flows of separated water at 70°C, the second stage was carried out by mixing the separated water at 70°C and the seal water with different amounts of the seal water, the third and the fourth stages were like the first and second but with the separated water at 120°C. The results show that this method is good if the mixture is around 50/50 separated water and seal water, to control the silica scaling in the separated water and to be able to reinject the seal water with the separated water. This does not eliminate the silica scaling in all of the separated water because the amount of separated water is much more than the amount of seal water that comes from the plant. .

Avskiljning av uran från dricksvatten med reaktiva filter :

Water is our most important provision and its quality is above all dependent on the geological conditions in the area from where it is extracted. Due to geological properties there are certain areas with an elevated risk of high uranium levels in the ground water, which in turn constitutes a risk for human health. Consumption of water that contains a high concentration of uranium implies a health risk due to the chemical characteristics of uranium. Livsmedelsverket (The National Food Administration) and Socialstyrelsen (The National Board of Health and Welfare) therefore recommend that precautionary measures should be taken when the uranium concentration in ground water exceeds 15 micrograms per litre. In particular, drinking water collected from Wells in areas with uranium-rich bedrock may have a harmfully high level of uranium. One of the Wells of the Ärla water purification plant, located near Eskilstuna, Sweden, contains water that exceeds the guideline of 15 micrograms per litre. One interesting technique for removing uranium from drinking water is adsorption to reactive filter materials.

Påverkan på Valboåsen från verksamheter inom Svedens industriområde samt närliggande områden : hot mot grundvattnets kvalitet och kvantitet?

The aim of this work was to find out what potential contaminants from roads, residential area and businesses within Svedens industrial area that can affect groundwater quality and quantity. Data collection was from SGU, VISS, internal material from Gävleborg county Administrative Board and Gävle municipality archive. GIS software ArcGIS was used to create the map images in the work. The studied area is located approximately ten kilometers west of Gävle city and consists of the esker Valboåsen, which is a glacifluvial deposit that in its central parts consist of coarse material that is overlaid by sand, clay and silt. North of esker Valboåsen there are the river Gavleån which has an inflow to the groundwater in the esker. This inflow represents the largest part of the groundwater recharge.

Främlingsbilder : Om judar och judendom i medeltida danskt och svenskt kalkmåleri

This thesis deals with the Jewish motifs of the medieval mural paintings in Denmark and Sweden; the presences of the motifs are of interest considering that no Jews were allowed entry into Scandinavia at the time. The purpose of the thesis is to study the Europeaninfluences in the medieval depiction of Jews and Judaism in the Danish and Swedish churches and the purpose for the production of the paintings. To this end, the Danish and Swedish mural paintings ? as well as the medieval texts and motifs of Jews and Judaismthat were used as source material ? are studied with respect to the attitudes conveyed. The Danish and Swedish mural paintings are unevenly distributed both within the groups of motifs as Wells as its chronological and geographical spread.

Behandlingseffekt av KBT för social fobi på en psykiatrisk öppenvårdsklinik

Social fobi är vanligt förekommande och tenderar att föregå andra diagnoser såsom depression. Huvudsyftet med föreliggande studie är att utvärdera KBT-behandling baserad på Clark och Wells (1995) förklaringsmodell för social fobi, genom att pröva behandlingsresultatet från en öppenpsykiatrisk klinik gentemot randomiserade kontrollerade studier. Studien baserades på data från 36 tidigare patientbehandlingar utförda av psykologer vid WeMinds specialistklinik. Som huvudutfallsmått användes förändringspoäng på skalor för social fobi som visade stark effekt, i nivå med jämförda studier. Därutöver uppnådde totalt 78 procent av patienterna kliniskt signifikant förbättring och 75 procent bedömdes vara i remission efter behandling.

Vattenjärnhaltens betydelse för mjölkkors hälsa och produktion :

Drinking water from drilled Wells has a high content of iron and other minerals in many places in Sweden. Questions about the association between the quality of drinking water and the health of dairy cows are regulary asked both by advisers and dairy farmers. There are so far not many studies published about the relevance for high iron content in water and dairy cow health and production. Therefore, the aim of this study was to investigate if there is a connection between the iron content in water and the health of dairy cows. Initially a literature study was made about iron and it´s function in ruminants.

Bedömning av vittnens minne : Kan träning förbättra förmågan att bedöma tillförlitlighet i vittnesmål?

Vittnesmål används idag som ett av de viktigaste bevisen i brottsmål. Samtidigt är felaktiga vittnesmål den främsta orsaken till att personer blir oskyldigt dömda (Wells & Olson, 2003). Forskning visar att det är svårt att bedöma vittnens tillförlitlighet. Det är dock klart att de flesta förmågor går att förbättra med träning och feedback. Syftet med studien är därför att undersöka om direkt feedback samt information om faktorer som kännetecknar korrekta vittnesutsagor har betydelse för förmågan att bedöma utsagors tillförlitlighet.

Nitrat i grundvattnet : Modellanalys av vattenflöde till Hörviks vattentäkt

A well, situated on Listerlandet in the western part of Blekinge in Sweden, has a very high content of nitrate. Water with a too high content of nitrate is hazardous to human health, in particular to small children. The area surrounding the well is mostly drained agricultural land with some larger farms for chicken and mink. The well takes its water from the bedrock and is deeper than most other Wells affected by nitrate. The bedrock in the area is dominated by limestone with a relatively high flow of water.This thesis was performed in order to find the source of the nitrate.

Prestandaförändringen hos en bergvärmeanläggning efter fem års drifttid

The aim of this report was to do a case study at a geothermal heating system which has been in operation for about 5 years, and study if its performance has changed during this period of time. A literature study about the processes involved was also done in purpose of background knowledge.The tenant-owner?s association Duvan at Petterslundsgatan in Uppsala installed year 1999-2000 a geothermal heating system. The purpose of this installation was that they hoped it would lead to a smaller usage of district heating which would lead to a reduction of the heating expenses for their buildings. The geothermal heating system consists of 19 energy Wells and 4 geothermal heat pumps, and it is one of the first systems of that size in the region of Uppsala.

Relationen mellan kommunikativa behov i vardagen hos barn med språkstörning och mål med logopedisk intervention

Samtalsanalys har tidigare använts som ett komplement till traditionellt använda standardiserade tester för att undersöka mer funktionella aspekter av kommunikation (Wells & Local, 1992; Yont, Hewitt & Miccio, 2002; Samuelsson 2009). Syftet med föreliggande studie är att utifrån sytematiska analyser av vardagliga samtal och logopedisk intervention utforska relationen mellan kommunikativa behov i vardagen och mål med intervention för barn med språkstörning.Tre barn med språkstörning filmades i vardagliga samtal hemma och på förskolan samt vid ett behandlingsbesök hos logopeden. Materialet transkriberades och analyserades enligt samtalsanalytiska principer. Intervjuer och retrospektioner genomfördes med föräldrar, förskolepersonal samt behandlande logoped för att ytterligare belysa barnens kommunikativa situation.I föreliggande studie framkommer att de kommunikativa behov barnen har relaterar till de mål som sätts upp i logopedisk behandling. På grund av deras fonologiska svårigheter påverkas barnens kommunikation då det ofta uppstår problemkällor, deras yttranden ignoreras och deras talutrymme inskränks.

Dricksvattenkvalite i enskilda vattentäkter : Landskrona kommun

Denna rapport är en sammanställning av de 100 undersökta enskilda brunnarna i Landskrona kommun vid årsskiftet 05/06. Det utfördes analyser på mikrobiologisk-, nitrat-, nitrit- och även kemiska bekämpningsmedelspåverkan. Syftet med denna rapport är att bearbeta och presentera analysresultaten av de 100 enskilda brunnarna i Landskrona kommun och försöka dra slutsatser kring dessa. Alla analysresultaten sammanställdes i tabeller och så småningom kundes vissa slutsatser dras kring varför resultatet såg ut som det gjorde. Resultatet visade att endast åtta av de 100 brunnarna var otjänliga gällande mikrobiologisk påverkan.

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.
