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.
Utvärdering av olika sätt att hantera avloppsslam i Värmdö
Important issues for the local authorities are what to do with the sludge produced insewagetreatment plants. The tax for landfill leads to higher costs with 250 SEK/ton. On the 31December 2004 it will be forbidden to landfill sludge.In Sweden the yearly production of sludge is 240 000 tons, counted as DS. The phosphorouscontent is 3 % in sludge. The total yearly production of sludge gives 6000 tons of phosphorous.
Tritordeum : evaluation of a new food cereal
Tritordeum is the result of a cross between a wild barley (Hordeum chilense) and durum wheat (Triticum turgidum). Tritordeum have high viscosity and a nice yellow colour. The objective of this thesis was to evaluate Tritordeum lines HT 354, HT 361, HT 437, HT 2218 (JB3) and HT 1608 (JB1) for use as a new raw material within the food industry. Analyses made were on dietary fibre, fructan, ash, water content and colour. Compilation of data from analyses made for Agrasys an Agri-Food company in Barcelona having the commercial rights to Tritordeum, included Lutein and rheological properties.
Trycksättning och dimensionering av brandhiss för berganläggning
This thesis deals with the design of a combinated rescue-, personal-, and firefighting elevator for a nuclear waste storage facility to be constructed by the client SKB, Svensk Kärnbränslehantering AB. SKB:s mission is to dispose of all nuclear waste from all swedish nuclear power plants. The storage facility will be built in the rock 450 m under the surface and will consist of several kilometers of tunnel where capsules containing the nuclear waste will be placed. It will also hold a central area which contains spaces necessary for the operation and construction of the facility, such as elevator hall, storage hall etc. The facility will have two ways of access: a vehicle ramp and an elevator shaft.
Behandlingsvåtmarkers reningseffekt på aktiva läkemedelssubstanser under vinterförhållanden : En studie av fyra svenska våtmarker för avloppsrening
Pharmaceuticals that are found in marine ecosystems are a threatening environmental concern, which is known to harm both animal and plant life. One of the reasons for this problem is that the waste water treatment techniques are not optimized to clear waste water from its pharmaceuticals contain. In this master thesis four Swedish treatment wetlands were studied, and their ability to reduce numerous pharmaceuticals in waste water. The four treatment wetlands that were studied were those in Oxelösund, Trosa, Nynäshamn and Eskilstuna. Two ecotoxicological tests and chemical analysis were used.
Följ upp målarbetet hellre än målen
Background: The Swedish population is aging [1] and malnutrition is a common problem among elderly people [2]. A method called food registration is used to monitor the patients? nutritional intake, with the purpose of reducing the risk of patients deteriorating in nutritional status during hospitalisation. However, the current method is not satisfactory and many food registration lists are incomplete. [3-6] Thus, patients do not receive a qualitative nutritional care since the assessment of the patients? nutritional status is based on incomplete documentation.Purpose: The purpose of this master thesis is to increase the quality in the nutrition monitoring process in the geriatric units B72 and B74 at Karolinska University Hospital in Huddinge, Sweden.
Uteservering för Hotell & Restaurang Villa Anna : urban odling i uteserveringsmiljö med storytelling som gestaltningsverktyg
In this paper, I design a new concept for a patio at Hotel and Restaurant Villa Anna in Odinslund, Uppsala, Sweden. Through this design, I examine how urban farming can thrive in a restaurant-context. The purpose of the design is to give the visitor a sense of the core values of the cuisine and to strengthen the sense of place by storytelling. My methods are comprised of a literature study on urban farming and storytelling as well as a discussion with the res-taurateur Rafael Löfstedt. I create a story of the place by examining its historical background and connect it to the current philosophy of the Villa Anna restaurant.
Att främja goda matvanor ? en intervjustudie med förskolepersonal i fokus
Bakgrund: Folkhälsan i Sverige beror till viss del på befolkningens matvanor. Matvanor grundläggs i de tidiga åren vilket ger den offentliga miljön, exempelvis förskolor, stora möjligheter att skapa goda förutsättningar för barnens matvanor. På såväl global som nationell nivå finns flera styrdokument som berör barns matvanor och hälsa. Det debatteras ofta vilka risker befolkningens matvanor innebär. Vi ville öka förståelsen för matens möjligheter genom ett salutogent perspektiv.
Lokala skillnader i konsumtion av påväxtalger och terrestra löv hos en differentierad population av Asellus aquaticus
That ecological and evolutionary processes can take place on the same time scale is a recent insight. Today we also know that they are directly linked to each other. In the lake Tåkern, in year 2000, there was a structural change when phytoplankton declined and submerged vegetation, mainly stoneworts began to spread. This led to evolutionary changes in the aquatic sowbug, Asellus aquaticus which had previously been limited to the reed, most likely feeding on detritus. But then, sowbugs could exploit the new habitat in stoneworts and a new food resource in terms of periphyton.
Matens roll i reseupplevelsen : En intervjustudie med sex nyckelaktörer i turismnäringen
Syftet med denna intervjustudie var att undersöka hur ett antal nyckelaktörer inom turismnäringen såg på matens roll och hur de arbetade med matupplevelser i praktiken. Insamling av data genomfördes genom semi-strukturerade intervjuer som transkriberades och analyserades utifrån en mall för kvalitativ bearbetning av text. De aktörer som fungerade som informanter för undersökningen arbetade samtliga med matturism på nationell, regional eller lokal nivå. De aktörer som deltog i studien var Landsbygdsdepartementet, Visit Sweden, Regional Matkultur Småland, Smaka på Skåne, Kristianstad Kommun och Idala Gård. Undersökningens resultat visade att samtliga aktörer ansåg att maten hade en given roll inom turismnäringen. Informanterna betonade vikten av att producenter ser matens potential till att bli en matupplevelse och synliggör den för turister. Ett skäl till att detta inte alltid görs kunde bero på den bild svenskar har av svensk mat och svensk matkultur menade informanterna. De förespråkade en stolthet över svensk mat och mattradition.
Vinn/vinn - eller svinn? En studie om hur livsmedel kan doneras till välgörenhet istället för att kasseras
Ungefär en fjärdedel av den klimatpåverkan som de svenska hushållen orsakar kommer från maten vi äter, eller närmare bestämt från de utsläpp av växthusgaser som maten ger upphov till på sin väg från jord till bord. Om maten slängs innan den konsumeras har denna miljöpåverkan skett i onödan. Uppsatsen undersöker VIS (Välgörenhet Istället för Svinn), en svinnåtgärd där fullvärdiga livsmedel istället för att slängas, skänks till välgörenhet. Målet är att undersöka hur VIS fungerar, samt att bidra till ökade kunskaper om detta för Sverige nya sätt att bemöta svinnproblematiken. VIS styrkor och svagheter, liksom de hot och möjligheter som kan finnas, har undersökts med hjälp av en SWOT-analys.
"Lärarna säger att man ska vara tyst och äta" : en kvalitativ studie av den pedagogiska lunchen
The title of the paper aims at a comment by one of the students during an interview. It reflects how most of the students experience the lunches in a specific school where the investigation is made. The question of pedagogical lunches has always interested me. Here I have used a method called the Grounded theory. I carried out a qualitative investigation with a number of methods such as interviews and participating observations.
L?t maten tysta mun? De nationella elevorganisationernas inst?llning till skolmat och skolmatsdebatt 1957-1982
The purpose of this study is to examine the Swedish national student organizations attitudes towards school food and the school food debate between 1957-1982. The previous research on the subject maps the historical background and development of the school meal, but lacks a contemporary student perspective from the chosen time period, not least on a deeper and more political level. The theoretical starting points in the study concern organizations and their influence on public authorities as well as student influence. These theoretical frameworks are used to describe the conditions for the currently active national student
organizations; Elevf?rbundet and SECO, in the political arena.
Barns eget perspektiv på ?bra? mat : en kvalitativ studie med elever i årskurs tre
This exam is about student?s perception of food and dietary advice. I illustrate food and eating from the youth's own perspective. The aim is to investigate how students perceive as "good" diet. It also reveals that students at the surveyed schools have poor knowledge of what is plate model.
En jämförelse av RDF och avfall som förbränningsbränsle
In the EU the amount of waste increased by 14 percent during the years 2000 to 2010. EU?s target to reduce waste generation runs parallel with the aim of increasing the efficiency and profitability aligned with energy recovery. In Sweden the energy recovery through incineration is increasing steadily, and 46 percent of the municipal solid waste (MSW) is treated by combustion. This report aims to examine the profitability of processing MSW into Refuse Derived Fuel (RDF) from an economic-, energy- and environmental perspective.
