Miljödammars funktion som kväve- och fosforfälla samt som bevattningsdamm i Sölvesborgs kommun

A study was made on four environmental ponds in Sölvesborgs municipality. The reason forthis was to see if the ponds had fulfilled some of the questions that was mentioned in theproject ?Rädda Hanöbukten?. The questions were as following; do the environmental pondsdecrease the leakage of nitrogen and phosphorus into Hanöbukten, do the ponds decrease theuse of groundwater in Sölvesborgs Municipality and are there any restrictions on what thewater in the ponds is allowed to be used for. In order to answer these questions aquestionnaire was made and interviews were held.

Uppgiftsfördelning inom arbetsmiljöområdet : En studie av delegeringen vid Örebro Läns Landsting

This essay describes how Örebro läns landsting operate concerning the delegation of work environment tasks in their organization. In the essay we review present law, with the focus on the delegation of work environment tasks. The purpose is to see if Örebro läns landsting are following the law in a correct way.Through interviews with people responsible for the work environment, and representatives for the workers in these questions, we could see how Örebro läns landsting were fulfilling there obligations in the role of employer. The result described how they were motivated and how they systematically worked with work environment issues. However, we could also see that the structure of the division of work environment tasks were inadequate.

Simulering av översvämningar i Byälven

Severe floods caused by heavy autumn rains in year 2000 raised the question whether measures to reduce the damage from high water levels, in the area surrounding lake Glafsfjorden and along the river Byälven down to lake Vänern, are possible. One option is to reduce flow resistance along the river and thereby lower the maximum water level a given inflow would cause. Good knowledge of hydraulic and hydrological conditions is necessary in order to estimate the effect of such flow-reducing measures. In order to quantify such effect a 1-dimensional hydraulic flow model has been set up for the river Byälven using the software package MIKE 11. The model is more detailed, especially concerning topography and bathymetry, than earlier models used for studies of the river.

Miljöstrategi: Miljökrav, profil, organisation samt medvetande : en jämförelse mellan Ica och Coop

The main reason for this project is my interest of our environment. What are our two largest grocerychains doing to maintain our environment? The aim of the project is to show the consumer which similarities and differences there are between ICA and Coop. My questions are: What are ICA and Coop doing to satisfy the demands to preserve our environment, are they going further than they have to? What do they think is important? Environment, price, consumer friendly? Answers: ICA and Coop are working to keep up with the demands, but are they doing more than they have to? The branch is a close world; it's hard to get impartial information. They are turning towards different consumer groups. ICA and Coop has different ways to interest consumers, ICA points out the importance of the meals, while Coop points at the environment. New questions has risen during my work: How far will their own brandnames go? Will ICA, Coop and others have their own farms, producers and suppliers? How can the consumer be protected? The competition will decrease with an increase of their own brandnames..

Den pedagogiska innemiljön i öppna förskolan : En kvalitativ studie om fem pedagogers tankar kring den pedagogiska innemiljön i öppna förskolan

The purpose of this study was to examine some teachers thought about the educational indoor environment in free preschool. With free preschool this study means a Swedish specially adapted to parents/adults and their children and for a typical type of children who are 0-5 years old. Questions to the study were:? How do some teachers in free preschool perceive that they are adapting the preschool indoors environment to children and learning?? How do some teachers in free preschool perceive that they are adapting the preschool indoors environment to children and learning to attract children to the pedagogical environment?In this study I used qualitative methods and interviewed five teachers and preschool indoor environment is observed. I applied the socio cultural perspective to my study.

Konduktivitet i vattendrag som indikator på sura sulfatjordar

Increasing attention is being given to acid sulphate soils wherever they occur. The problems that leaching sulphate soils gives with significant lowerings of pH and mobilization of heavy metals influence large spectra of our society from fisheries to agriculture to construction. Mapping these soils is consequently of great importance and the methods of doing this is very much lacking in function and precision. This study was therefore carried out to investigate whether conductivity in running water can be used as a simple instrument to identify acid sulphate soils in the catchment. 31 coastal streams in the county of Västerbotten were analyzed for different catchment properties such as occurence of marine sediments and basic water chemistry including conductivity and sulphate.

Värmeåtervinning ur spillvatten i befintliga flerbostadshus

Drain water heat recovery is an uncommon measure in multi-unit residential buildings. There istechnology available for the purpose but the knowing and experience of the heat recovery systems islittle. The purpose of this thesis is to evaluate the future potential of drain water heat recovery inmulti-unit residential buildings.A major part of the multi-unit residential buildings in Sweden were built during modernismen andrekordåren (1940?1975). Many of the buildings have worn out drain and water supply systems andmany are in need of a general refurbishment.

Mineral composition of New Zealand monofloral honeys

The objective of this study was to determine the mineral content in ten New Zealand monofloral honeys, in order to distinguish whether New Zealand monofloral honeys are a good source of minerals compared to honeys from other parts of the world. The ten monofloral honeys were collected from a local honey factory (Airborne Honey Ltd, Leeston), Clover, Honeydew, Kamahi, Manuka, Nodding Thistle, Rata, Rewarewa, Tawari, Thyme and Vipers Bugloss honeys were been investigated. The water content, water activity, pH, conductivity, colour and mineral content were evaluated. The water activity was averaged for all the ten New Zealand monofloral honeys and set to 0.59 aw, which indicates a high stability and long shelf life as a food stuff. A strong correlation between total mineral content, pH, conductivity and colour was obtained.

Fånggrödor i Norra Östersjöns vattendistrikt

70 % of the lakes and waters in the water district of northern Baltic Sea do not reach the requirements for good ecological status. This is mostly due to eutrophication caused by a too high deliverance of nutrients from agricultural land or effluents. Losses of particulate phosphorus through water erosion contribute to a great extent to this eutrophication. In the action plan for the water district cover crops are mentioned as a measure for reducing losses of phosphorus from arable land. This paper reviews the possible effect of cover crops in the water district and discusses what crop that would be most suitable.

Spillvärmeåtervinning

SAPA´s resource of waste heat is the basis for this thesis to investigate the possibility of energy assets in their cooling water and possible uses for it. The energy in the waste water is greater than the current need which has three uses which are (1) heating the factory, (2) converting liquid propane to propane gas and (3) local domestic heating. The average energy load that is available is 1, 7 MW and the average temperature in the cooling water is 41°C. The total energy load at dimensioning out side temperature is approximately 1,6 MW for the three current uses. The temperature is currently too low to be used directly in the existing systems so an upgrade is needed.

Personliga assistenters fysiska arbetsmiljö utifrån arbetsledares perspektiv

Abstract:Because personal assistance is relatively new in social care in Sweden we were interested in to get more knowledge in how supervisors for personal assistants worked. In our study we choosed to look into how the supervisors worked with the physical work environment for the personal assistants. The questions we wanted to found answers for in this study was, which work directions the supervisors for personal assistants have around the physical work environment, which legal provisions there were around the physical work environment for the personal assistants and how the supervisors experienced the work with the physical work environment for the personal assistants. We did a qualitative interview study with supervisors for personal assistants. We realised in our study that there were big differences in how the supervisors for personal assistants worked with the physical work environment for the personal assistants.

Geotermisk fjärrvärme i Gunsta

Gunsta is situated about 10 km east of Uppsala. Today there are plans to establish 1000 new households in Gunsta before year 2030. The required energy for heating houses and water would be distributed via a district heating system, which also includes 200 existing residences. The annual required energy, according to this study, would be 16.2 GWh with a maximal peak effect of 6.9 MW. To meet this need, the study suggests a system with heat pumps to upgrade the 31?C water from a 1.8 kilometre deep borehole.

Comparison of three IVC systems for mice, with focus on growth and nest building in juvenile mice

Today the individual ventilated cage system (IVC-system) is the most commonly used system when housing rodents. IVC systems are designed to control both supply and exhausted air at cage level, as well as temperature and relative humidity in the cages. This creates an optimal environment for the mouse and at the same time a protection against the risk of cross-infection between cages and the outside environment. The aim of this study was to evaluate the health and welfare for two different strains of laboratory mice (NMRI nude mice and C57BL/6NCrl mice) in three different kinds of IVC-systems; Arrowmight, Allentown and Tecniplast. 108 mouse pups from each strain (in total 216 mice) were selected after weaning at an age of three weeks and tested during 5 weeks.

Ett gårdsbesök : ger besöket någon kunskap om mjölkproduktion?

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.
