Fjärrvärme - ny lokalisering av kraftvärme i Enköping

The municipality of Enköping is presently working out a new layout plan for the town of Enköping and new residences are planned in the harbour area. Because of these plans, the municipal energy company ENA Energi may have to move its location from the harbour to another part of the city.The aim of this degree project is to investigate the possibility of building a new CHP plant in another area of Enköping. The future demand on district heating and infrastructure at the new location have been projected. A new CHP plant has been dimensioned and economic analyses concerning the project have been made.Results show that the future demand of district heating in Enköping will differ a little from the present needs. In 2030, the district heating production is expected to be c.

Handbok för växtinsamlare : med erfarenheter från sex nutida svenska experter

What makes a Swede betake himself into the Chinese wilderness? How does the Rio Convention influence a plant collector? And who will crack the nut positioned 12 meters up in the crown of a tree? There are many secrets behind the act of collecting plants. In many regards, the documentation of the collection of plants for a Swedish purpose has been unsatisfactory. The focus of the publications is on what plant species that have been found rather than information on how these plants have been collected. Only few results of experimental cultivation are available. There is no doubt that there exists knowledge that has not been publicised yet.

Brunnsviken : Utvärdering av åtgärder för förbättrad vattenkvalitet

Periods of hypoxia are a recurring issue in Brunnsviken. Main factors that trigger hypoxia in Brunnsviken are eutrophication  due to anthropogenic emission of nutrients, stratification in the water column due to salinity and temperature differences  that prevents mixing and a sill inlet that prevents water exchange. As an attempt to improve the oxygen levels, bottom water is pumped from Brunnsviken causing aerated surface water to flow back into the basin.  The objective of this Master?s thesis was to study the change in dissolved oxygen levels due to pumping.

En Grupp Patienters Upplevelse av Sjukgymnastisk Huvudvärksbehandling

There are several treatment methods that are used by physiotherapists to treat migraine and tension type-headache (TTH). The effects of these methods have been evaluated in previous studies. However, there are few studies evaluating headache patients own perception of the treatment. The purpose of this study was both to examine the patient?s perception of the physiotherapy headache treatment and to examine if the treatment had effect on their quality of life.

Concentration and offtake of trace elements and macronutrients in Italian ryegrass (Lolium multiflorum Lam.) and spring barley (Hordeum vulgare L.) grown on soils amended with water treatment residual sludge

Aluminium sulphate (Al2(SO4)3) is usually added during the drinking water treatment processin order to precipitate organic and inorganic material, resulting in aluminium-based drinkingwater treatment residual sludge (WTR). Since 2003 Swedish law no longer permits WTR tobe deposited in lakes, and there is an interest to explore the possibility to utilize WTR as soilamendment. The aim of this study was to examine the effects of WTR application on cropgrowth and concentrations of macronutrients and trace elements (including micronutrients andpotential toxic elements). A greenhouse pot experiment was conducted with three soils; a clayloam rich in phosphorous (P), a loamy sand rich in P, and a silty loam with a low soil Pconcentration, and two crop species Italian ryegrass (Lolium multiflorum Lam. cv.

Termografisk undersökning med samtidig analys av rektaltemperatur, hjärtfrekvens, psykiska reaktioner och specifika blodparametrar av häst som behandlats med vibrationsboxen Vitafloor :

A number of studies in human medicine has documented positive effects of whole body vibration treatment in humans. The Vitafloor system, witch is based on treatment of horses with vibration, has the purpose to be used in training of healthy horses and as rehabilitation for horses with injuries in their musculosceletal system. The purpose of this study was to analyse what happens with a clinically healthy horse during treatment with Vitafloor. The methods used is mainly thermography before and after treatment, but also blood samples, measurement of rectal temperature, heart rate, clinical examination and observation of psychic reactions has been done. Statistic significant changes in skin temperature in hoofs and fetlocks of front legs has been observed after treatment with Vitafloor. Analyzing of the blood samples showed a tendency for decrease in Kalium, and two of the horses had changes in CK. No negative effect has been observed with the treatment of horses with Vitafloor, and the horses seems to like the treatment. .

Med alliansen som utgångspunkt ? Behandlingspersonal och ungdomar om positiva förändringsfaktorer för ungdomar inom institutionsvården

The practice of residential treatment of youth has been up for debate for quite some time. The debate regarding institutional care has voiced concerns regarding the lack of follow-up and evaluation of treatment and its efficacy. It is especially important with additional research on residential treatment conducted from the perspective of those being treated, as well as the treatment providers. This study aims to add to this field of research. The study is based on two empirical studies conducted through qualitative interviews.

Fosforavskiljning i reaktiva filter vid småskalig avloppsrening

An excessive input of nutrients to lakes and other water bodies has created a problem with eutrophication in Sweden. Untreated, or partially treated, domestic sewage is a major source for discharge of phosphorus (P), which is the nutrient most frequently responsible for eutrophication of most fresh waters and the Baltic Sea. The waste water can be cleaned by filter materials, which have a high P-retention ability and which after saturation may be used as fertilizers. Four potentially suitable filter materials were tested in batch- and column experiments in this study. In the batch experiments, the following materials were shaken with waste water in time series ranging from 5 seconds to 60 minutes: coarse (1-4 mm) and fine (0-2 mm) Polonite® (heated bedrock from Poland); Filtralite® (light expanded clay aggregates with limestone added before burning); water cooled blast furnace slag (BF-slag) and BF-slag mixed with 10% burned limestone.

Rening av avloppsvatten från biltvättar med filter av torv och inblandad kolaska : en utvärdering av effektivitet och avfallshantering ur ett miljöperspektiv

Filtermaterial av 75 % torv och 25 % kolaska har använts under 2 respektive 4 år för rening av avloppsvatten från två biltvättar. Jämförelse med Kristianstads kommuns riktvärden för avloppsvatten från fordonstvättar visar att filtren fungerat. För avfallsklassning krävs kunskap om innehåll av miljöfarliga ämnen i produkter som använts i tvätthallarna. I brist på kunskap om innehåll av ej analyserade miljöfarliga ämnen i filtren anses förbränning vara ett bra omhändertagande ur miljösynpunkt, då energi och aska återvinns..

Nutrient effects on microorganism communities in nutrient poor soils

Better, more efficient fertilizers with great productivity and economic returns are needed, but it is important today to find fertilizers that are also sustainable. It is also important to carefully monitor their impact on the environment, including potential side-effects. In this context, the microbial communities that carry out numerous essential functions contributing to a functional ecosystem are of particular interest. The present study is a complement to a pot experiment that investigated the potential of different waste products for use as fertilizers and how they affect the microbial community. In the pot experiment, the clearest treatment change in microorganism community function was found in the fully fertilized treatment used as a positive control. The question was whether this was indirect, i.e.

Identifiering av fosfatfosfors käll- och flödesfördelning i ett litet jordbruksområde

Eutrophication of lakes and streams are nowadays a well known environmental problem and implies an enrichment of the nutrients phosphorus (P) and nitrogen (N). Phosphorus is considered to be the most important component for the growth of aquatic plants and leads in too large quantities to an intensification of growth. Phosphate (PO4) is the fraction of phosphorus that can easiest be taken up by plants and thus have the greatest impact on eutrophication. Increased plant growth in lakes and unfavorable conditions for aquatic animals are two examples of negative consequences. A significant portion of the increased nutrient supply to nearby water can be derived to phosphate leaching from agricultural areas, where private sewers and agriculture is two main sources.

Matavfall från livsmedelsbutiker : - En analys av den kommunala hanteringen i Sverige samt en detaljstudie av förhållandena i Umeå kommun

Food waste from grocery stores - An analysis of municipal management inSweden and a detailed study of the situation in Umeå municipalityThe objective of this thesis was to analyze the municipal management of food waste fromgrocery stores in Sweden in general and in Umeå municipality in particular. Furthermore theobjective was to account for the different waste treatment methods that can be used and toevaluate them from an environmental perspective. In order to analyze the municipalmanagement a survey was sent to all of the municipalities/municipal waste companies inSweden. A general comparison of treatment methods was carried out on the basis of ascientific review and a system analysis was performed in order to compare three differenttreatment alternatives for the food waste generated in grocery stores in Umeå. The surveyshowed that the legal definition of food waste from grocery stores is unclear and variesbetween municipalities.

Alternativ uppvärmning av reningsverket på Utö - En studie av energibesparingsmöjligheterna i syfte att minska uppvärmningskostnaderna

The projects objective is to find an alternative method of heating (the current method being via electric heating) the sewage treatment plant on the island Utö in Stockholm?s archipelago in order to reduce the energy consumption and ultimately the cost for heating the plant. The project is given by ?Skärgårdsstiftelsen? (The Archipelago Foundation) and is a part of the larger EU-project ?Green Islands?.A model for the plants total heating demand is established in order to get a good perception of how much money can be saved using alternative heating methods. The heating demand model gives an annual heating demand of approximately 32 500 kWh and a maximum heating power demand of around 24,7 kW.

Vad är NARCONON? : Synen på behandling inom ramen för en religiös ideologi

The purpose of this essay was to describe the opinions of different religious and non-religious ideologies and aspects of treatment, concerning use of drugs and drugsaddiction, and with a special focus at Narconon. We also wanted to try to understand the connection between professionalism and ideology in their treatment.Our central questions where;· How does the treatment Narconon's provides, look like?· What is Narconon's opinion on use of drugs and drugaddiction?· What is Narconon's connection to the Scientology?· Is there any scientific proof that Narconon's treatment is functioning?· How can we understand the connection between professionalism and ideology in treatment?We made intervjues with six social workers and six intervjues with staff at Narconon. Added to the intervjues, we studied articles and Internet research.From our work and through information we have got from Narconon, we have discovered the need of further research concerning their treatment. Narconon does continuous following-ups when the treatment is finished.
