Damages and problems in communal swimming facilities ? an inventory
Bakgrund: De flesta inomhusbadanläggningar är idag 30-60 år gamla och många anläggningar har stora problem med skador på både byggnader och bassänger. Skadorna är ofta så pass allvarliga att det inte längre är lönsamt att renovera utan på många platser planerar man att bygga nya bad. För att undvika framtida problem är det viktigt att dra lärdom av vilka skador och problem som har inträffat samt hur man vid nybyggnation och renovering ska kunna undvika dem. Vid byggande av dagens inomhusbadanläggningar tillämpas främst tidigare branscherfarenheter. Det faktum att så stora brister och omfattande problem förekommer, tyder på att kunskapen är otillräcklig.
Grb10 and developmental programming: evaluation of a maternal diet restriction model during gestation
This study was conducted at the University of Bath, UK, from September to December 2014 as part of an ongoing research project aimed at elucidating how the Grb10 gene might act as a mediator of long-term health effects (such as predisposition to obesity, diabetes, coronary heart disease and hypertension) caused by environmental factors during development. This phenomenon is known as developmental programming.
The purpose of this thesis was not primarily to answer any of the broader questions posed by this research project at large since this would require much more data than is reasonable to acquire over the course of a few months, but rather to evaluate the methods used in this project and reveal whether they are working the way they are presumed to. In the research project, which employs mice with the Grb10 gene knocked out as well as wild-type control mice, a dietary restriction model is utilized during gestation, which is supposed to generate offspring with lower birth weight and subsequent detrimental health effects in adulthood. This is supposed to be achieved by restricting the protein content of the pregnant mothers? diet to 9 % (as opposed to the control diet of 20 %) throughout gestation.

Urinsorterande toaletter : rensning av stopp samt uppsamling och attityder
It is important that the current urine separating systems are evaluated to allow improvements to be made and consequently increase their future propagation. In order to increase the knowledge about urine separating systems this study was made. It included, among other things, measurements of amounts of urine as well as of the composition of urine collected at Nytorgsgatan 4 in the city of Hallsberg. The study was increased after an inquiry that also included the district of Understenshöjden in the city of Stockholm. In the inquiry, the users were asked questions about odour, cleaning of toilets and occurrence of blockages in the urine water locks etc.
Det dubbla uppdraget. Utbildades syn p? det dubbla uppdraget.
This study examines the experiences and perspectives of after-school program teachers through a qualitative research approach. The purpose is to deepen the understanding of their experiences within the after-school setting and how these insights might contribute to the development of this environment. Semi-structured and narrative interviews were used for data collection, allowing a flexible and open conversational format where participants could express both concrete opinions and implicit thoughts. Following Ahrne and Svensson's (2022) argument, which emphasizes the importance of qualitative interviews in capturing experiences of individuals active within specific social settings, this method is considered well-suited for the study?s purpose.
The narrative interviews provided the interviewees with the freedom to describe their own experiences in detail, while the semi-structured interviews ensured a foundational structure and opportunities for follow-up questions.
Behovsanpassad bevakning
The market for security is one filled with great opportunities. The security services companies are numerous and diverse, the Swedish market is dominated by two large companies: Securitas Bevakning AB and Falck Security AB. In this study we have focused on the bigger of the two, Securitas. This report describes and analysis the security service branch and its surroundings in an involved manner. The target group of the result is mainly people within the security branch.
Decision making and the role of empathy in animal ethics committees (AECs)
Ethical evaluation of scientific studies carried out using animals is legally mandated in many countries and has been so in Sweden for over three decades. The animal ethics committees (AECs) responsible for the task have however been subjected to criticism; common critique being that the wrong issues are discussed and that the ethical evaluation is thus incomplete, that there is a lack of coherence across committees and that the committees are not as democratic as they might appear. This study investigates the view of Swedish AEC members on a number of issues in order to shed some light on the mandate and functioning of the committees, and on the grounds for ongoing criticism. In a survey and interviews AEC members and other persons connected to the committees gave their views on the AEC task in relation to their roles, the ethical evaluation per se and whether or not emotions such as empathy play any part in it. There were significant differences found between AEC member categories and several issues were encountered, many of which have been stressed in previous studies.
Fler mötesplatser i våra utemiljöer ? en länk i arbetet med ökad integration i Malmö?
I have in this essay, studied both the definition of the concepts segregation and integration and how you as an urban planner can promote integration, by working with increased feeling of security and more venues. The aim is to cast light on these two tools and how you within city planning can use them to create a more equal society. To gain a wide base of knowledge, I have studied both government and municipal reports as well as prior investigations where these methods have been used. I have also interviewed a landscape architect who actively works with questions regarding integration in Malmö, to get information as recent as possible about their work today. Malmö is today a segregated city with large gaps between the residential areas when it comes to economic possibilities and the composition of inhabitants.
Brandpåverkan på samverkanskonstruktion : En utvärdering av betongfylld stålprofil
En samverkanspelare drar nytta av interaktionen mellan det omslutande stålröret och profilens betongkärna för att därav erhålla en ökad lastkapacitet. För att förstå beteendet och effekterna av interaktionen mellan stål och betong är det viktigt att förstå de enskilda materialens beteende. Betongens huvudsakliga uppgift i en samverkanspelare är att ta upp tryckkrafter medan stålets främsta uppgift är att motverka momentpåkänning och uppta dragkrafter. I normal rumstemperatur samverkar stål och betong för att bära den aktuella lasten.Samverkanspelaren har stor potential med avseende på lastkapacitet. Nedan tas några av de förväntade positiva effekterna av interaktionen mellan stål och betong upp:Förekomsten av buckling för stålet försenas samtidigt som den försämrade bärförmågan efter lokal buckling uppstått dämpas, beroende på betongkärnans återhållande effekt.Förhindrar spjälkning och hållfasthetsnedsättningen för betongen blir inte lika drastisk.Ökad tryckhållfasthet och deformations kapacitet, speciellt för grövre tvärsnitt.Vid ett brandscenario utsätts pelaren för en temperaturhöjning.
MÄTNING AV LUFTTÄTHET I FLERBOSTADSHUS : Gällande krav, praktiskt genomförda mätningar samt en tillämpbar metod
Stor förvirring råder kring hur lufttätheten ska mätas i flerbostadshus. De metoder som finns och de resultat som erhålls vid täthetsprovning av småhus är inte alltid applicerbara på flerbostadshus även om mätenheterna är de samma. Detta föranleder problemställningen för detta examensarbete:Varför och hur kontrolleras lufttätheten i ett flerbostadshus på ett praktiskt tillämpbart sätt, som också gör det möjligt att jämföra resultat från olika objekt?Metoderna som används för att undersöka detta är litteraturstudier och samtal med erfarna personer, samt demonstration av en mätmetod i fullskala. En diskussion med initiativtagarna till detta examensarbete leder fram till en rekommenderad metod och en mall för hur detta ska utföras.Byggnadsskalets luft-, diffusions- och vindtätning har stor betydelse för en byggnads energianvändning, fuktsäkerhet, termiska komfort och hygien, luftkvalitet, ljudmiljö, spridning av brand samt spridning av luftföroreningar utifrån och in.
Nytt ventilationssystem till djurstallar :
There is two dairy farms in Sweden with ability to be opened on both long sides, one outside
Hjo and the other one, Brandstadholm, north of Sjöbo. When there is no measures and results
or not enough literature about natural ventilation and especially on this kind of air inlet, makes
my tests very interesting not only on Alnarp, but among other companies.
I would like to find out if there is any air movements direct on the cows, how high/low
temperature, air humidity, light intensity and noise standard inside the barn. Does
Brandstadholm fulfil the rules and regulations when it comes to climate inside the barn? Could
this system become the new dairy barn instead of the conventional barns in Sweden?
I am going to focus on the animals environment, after all they are the one who is going to
spend the most of the time in the barn.
I used five electrical loggers distributed inside the barn to measure the temperature and one of
the loggers measured the air humidity, every 15th minute. One logger were placed on the
outside which measured both temperature and air humidity.
Kundanpassad tjänsteutveckling och förändrade relationer inom den försvarsindustriella sfären
The aim of this thesis is to describe the customer?s attitudes toward the contracting for availability, i.e., which factors are from the customer?s perspective necessary for the fulfilment of a supplier-customer agreement? Furthermore, the objective is to describe and analyse a supplier-customer relation in the Defence Industrial sphere.The present study has been carried out as a case study using an abductive approach. The thesis is based on a practical problem, i.e. which factors will be important to the customer when a contractor in the Defence Industry wants to increase its commitment of service, and how will their relationship change? The thesis is above all focused on generating knowledge that can lead to rapid and concrete measures and that can be used in the analysis of an increased industrial commitment but also as a case study of a problem of a more general nature in the Defence Industry.
Barn med utvecklingsstörning och en kvalitativ innehållsanalys av TEACCH-metoden och Lilli Nielsens pedagogik med avseende på kunskapssyn
SammanfattningMålet med det här arbetet är att analysera två pedagogiska metoder för barn med utvecklingsstörning, närmare bestämt TEACCH-metoden och Lilli Nielsens pedagogik, när det gäller kunskapssyn och då framförallt aspekterna hur barnet med utvecklingsstörning tillägnar sig kunskap och vilka former denna kunskap tar. Avslutningsvis undersöks vilka kategorier som kan identifieras ur de analyserade texterna (citaten).För att samla in data har jag använt mig av litteraturstudie men för att tolka och bearbeta data har jag valt att använda mig av kvalitativ innehållsanalys. Litteraturstudie innebär att jag söker efter specifika svar i litteraturen som jag sedan jämför.När det gäller frågeställningen hur barnet med utvecklingsstörning tillägnar sig kunskap enligt TEACCH-metoden har jag funnit följande kategorier: Strukturerad miljö, strukturerade aktiviteter och? hand på hand-metod?. När det gäller frågeställningen vilka former denna kunskap tar enligt TEACCH-metoden har jag funnit följande kategorier: Faktakunskap och Färdighetskunskap.
Klyftan mellan byggare och arkitekt : markentreprenören och landskapsarkitekten
In my work I have received a lot of concrete advice about improving the cooperation between landscape architects and contractors. Here is a list of suggestions from both cathegories:
Landscape architect's advice:
? Be humble, show respect.
? A practical approach makes cooperation easier.
? Call together a startup meeting with all the consultants and builders.
? Establish a network of contacts with serious
contractors whom you can recommend to
customers.
? Don't hesitate to ask the contractor for advice; they often have lots of useful knowledge.
? It is important to have clearly written and thoroughly worked out documentation.
? Never let a newly graduated landscape architect visit the buiding site without the company of an experienced colleague.
GODTROSFÖRVÄRV AV FRITIDSBÅTAR : En komparativ studie gällande köparens undersökningsplikt
AbstractMedia has since a long time back been writing about extensive thievery of recreational boats and their engines. The value of the stolen goods is estimated to several hundreds of million Swedish crowns per year. The widespread stealing creates a secondary market where boats sometimes are sold by sellers that do not have the rights to sell the boat. This creates risk for the buyer who most often is a private person. A situation the buyer can face is that the boat was stolen and that the original owner can demand to get the boat or engine back.
