Hur skapar man en funktionell och beständig dörrmiljö? : En närmare studie av ståldörrar
Today?s construction buildings contain more advanced technologies than before. The development of newer and stricter regulations to the construction industry makes the door environment more and more complex.In large construction projects the door environment is held up as a major challenge to get to in a good way. It turned out after a discussion with one project manager and a site manager at NCC, that the door environment is difficult to get right in major construction projects and it often causes many error reports in to the aftermarket after that the final inspection is completed.Interviews have been done with key figures in the building process at NCC and Akademiska hus. A study on a university building for around 3500 students and with 300 workplaces was made.
Förskolegård för ett Reggio Emilia inspirerat tankesätt :
The shape and arrangement of the outdoor environment at a preschool has a critical
impact on the possibilities to practice different pedagogic activities (Grahn et al.1997). At the preschool at Edwin Ahlqvists road, the employees are inspired by Reggio Emilia in their way of thinking, and they consider their outdoor environment is not suitable for the pedagogic activities they use. Reggio Emilia is a city in the north of Italy (Wallin 2001). The preschools there are famous for their pedagogy, their creativity and their democratic way of working (Dahlbech & Johansson 1986). The Reggio Emilia pedagogy is constantly renewed and developed, but with the children?s needs in focus and simultaneously with the quick changes of the modern society.
Analys av stationsplattformsutformning ur ett säkerhetsperspektiv
Train travel has increased in Sweden, and future increase of train transports putdemands on the already vastly exploited railroad net. The increased need of capacitycan be seen in the ongoing and planned expansions of the railway track. One part ofthe railroad infrastructure which is affected by an increase of travellers is the design ofthe station platform. Since the platform is the place where the traveller meets thetrain, dangerous situations can occur in this environment. A number of studies focuson single safety risks, albeit there is no research to show the full picture of safety inthe platform environment.This study aims to treat and put together a compilation of risks for the traveller in theplatform environment in the form of a checklist, which can be used as support inplanning and design of a safer platform environment for existing or planned platforms.The thesis has, through case studies of five ongoing projects within the NationalRailroad Administration (Banverket), interviews with train company personnel andinternational railroad administrators, identified and treated safety (and security) risksin the platform environment.The conclusion of the study is that the relations between the traveller, the physicalplatform environment and the project organisation are important to explore andexploit when designing effective safety measures.
Alléers användning genom tiderna i Sverige : en bakgrund till alléns framtida utveckling
Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.
Stadsdelsförnyelse på Öster i Gävle : En analys av fysiska faktorer för en bättre boendemiljö
Nearly 50 years after the building of the first million programme neighbourhoods many Swedish municipalities faces an extensive restoration work in these neighbourhoods which during their relatively short lifetime have acted as a target for a large amount of criticism. Öster in Gävle is a million programme neighbourhood that has gone through an extensive restoration between 2001-2009 with the aim of improving the living environment. Improvements have been made in the outdoor environment, to the facades of the houses and the entrances? of each building. The purpose of this study has been to investigate the effects of the renewal in the physical outdoor environment for those who live in the neighbourhood.
Epoxidised linseed oil as hydrophobic substance for wood protection : technology of treatment and properties of modified wood
Public concern about the release of toxic compounds from wood-based products drives legislation towards enforcing industries to find and use more sustainable solutions for wood treatment. Plant oils are good alternatives to treat wood, minimizing or even neutralizing the impact on the environment. Wood modification with epoxidised linseed oil (ELO) and acetic acid as catalyst has proven a suitable method to impregnate and protect wood. However, the mixture presents a serious inconvenience because of the quick polymerization of the ingredients that limits its practical application. Therefore, this study was designed to evaluate an alternative method using a two-step process which bypassed the problem above.
Sjuksköterskors arbetsmiljö inom slutenvård och äldreomsorg : En litteraturstudie
AbstractThe aim of this study was to illuminate and collect existing research from the beginning of the 21 st century about nurses work environment in institutional and elderly care in Sweden.A literature review was made by analyzing eleven scientific articles. The result showed mainly information about nurses work load. The information dealt with high work demands, too much responsibility, shortage of staff, time press and stress. Furthermore nurses reported a lack of co-operation between staff and management. An important part in nurses? work was appreciation from colleagues, management, patients and relatives.
Undersökning av deponerat ferrokromstoft : Utvärdering av ny behandlingsmetod
The production of ferrochromium alloys at Vargön Alloys AB contributes to formation of unwanted ferrochromium dust, which contains toxic Cr(VI). The dust is since summer 2005 treated with an iron-sulphate solution to reduce Cr(VI) to the non-toxic Cr(III). A year later the treatment technique was improved and disposal occurs in cells on the landfill. The cells can be up to 300 m3 and the edges can be made out of fro example concrete. Tests are conducted on the treated dust when it is disposed.
Högskolan i Halmstads miljöarbete - syndliggörande för studenterna
We must all take our responsibility to our common environment, we have to make sure that the following generation is guaranteed a healthy and good environment. Swedens universities have a significant role too achieve this. Environment questions have to integrate in the educa¬tion as a compulsory element, then more people will have an increased comprehension for the influence we have ion the environment. . My degree project have I decided to do about the environmental work at Halmstad University.
Utemiljöns betydelse för barns utveckling
The outdoor environment is the first thing you notices when you come to a pre-school and it also plays an important part in the development of children, their play and meeting their large motor needs. It is important that the outdoor playground is stimulating and inviting.My goal is to examine if the outdoor environment plays any role in the development of children and their interest in nature. What kind of thoughts do teachers and parents have about outdoor play, and is there a developmental goal for the children as well as what role do the teachers play in reaching these goals. In my work I want to show how an outdoor environment should be formed to help educationally as well as be safe and not least of all fun to be in..

Att lära tillsammans genom musik - En studie av hur rytmikpedagoger skapar en god miljö för lärande
This study is about how eurhythmic teachers create a comfortable and educational environment in their classrooms. In other words how they create a healthy working environment. Four teachers were chosen for the study, one of them male. I?ve used qualitative interviews because I believe it's the best method to collect information that illustrates what a teacher's working situation looks like and what he/she does to realize their own ideas.
Arbetsmiljö i stora mjölkkobesättningar :
Earlier studies have shown that musculoskeletal disorders among animal keepers are
more frequent than in other occupations. Most of the farms have expanded and the
farmers who used to work alone have suddenly become a work manager with several
employers. There are only a few studies made on the work environment in dairy farms.
Our study is based on a questionnaire and is a part of a project called large dairy herds.
The study is based on data from the persons who milk most of the time. The questions
they had to answer were about the work environment, musculoskeletal disorders and the
psychosocial environment. The results of the survey are presented in diagrams and
figures.
It was common that the dairy producer themselves answered the questionnaire.
Mixture and single-compound toxicity using Daphnia magna : comparisons with estimates of concentration addition and independent action
Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.
Fö?rskolans inomhusmiljö? i relation till barns lä?rande : En studie om pedagogers arbetssä?tt på två Reggio Emilia-inspirerade förskolor
Background: The request for the Reggio Emilia practice has expanded enormously the last couple of years within the Swedish preschools. This particular practice describes the environment as a third educator. This third educator is supposed to work as - not only a tool - but also a support to ease children's learning experiences and help develop their mind. Previous research has shown that design of, for instance, furniture has a way of affecting the children's learning process and development.Aims: The purpose of this study is to see how two different teams of preschool educators on two differed Reggio Emilia inspired preschools work and handle the physical indoor environment. Method: We started out by contacting Reggio Emilia inspired preschools.
