Moisture damage in kitchens is an area that many people believe to be irrelevant andnot a subject to concern, however the problems encountered might be larger thananticipated.The purpose of this essay is to get a view of how problematic moisture damagecurrently is as well as what can be done to prevent damage during the constructionand building of new housing.Statistics regarding moisture damage as well as several tools for damage preventionhave been studied and investigated. Industrial regulations have been reviewed tounderstand the requirements construction companies must legally follow during theconstruction and building of new kitchens. Home manufacturers and largerentrepreneurs have been contacted in order to get their point of view regarding theproblems with moisture damages in kitchens.The knowledge of moisture safe constructions is prevalent by home manufacturers,insurance companies and entrepreneurs. Despite this knowledge, the constructioncompanies predominately follow the industries regulations, which normally onlyimplement the minimum requirements.In order to get construction companies to design and build kitchens with increasedmoisture security, stricter industrial regulations might be needed to be implemented.Unlike bathrooms and laundry rooms, kitchens are not defined as a ?wet room? andthe regulations for the construction of kitchens are more lenient.It is difficult to detect water leaks in an early state and the moisture damage is usuallyextensive before it is discovered and repaired if the kitchen lacks moisture securedconstruction and water security.

The aim with this thesis is to make a comparison between forcing tulips in a hydroponic system and the forcing off tulips that have been planted in soil. The results are mostly based on interviews with six Dutch and one Swedish tulip forcer and the managing director at the Horticultural Research Centre, Proeftuin Zwaagdijke, in the Netherlands. There are benefits and disadvantages with both methods. Tulip bulbs planted in soil seem to get a brighter colour after forcing, compared with those forced ?in water?.

This project operate an environmental assessment of total waste was conducted by using a life cycle assessment (LCA), that examines the environmental benefits of recycling production waste from Atlas Copco at Stena recycling. Atlas Copco is a company engaged in the development and production of rig-mounted hydraulic breakers and handheld air breakers and handheld motorized rotisserie. Stena recycling is a recycling company engaged in recycling, processing and refining of metals, paper, electronics waste and hazardous waste.The purpose of this study is to focus on Stena customer Atlas Copco and evaluate environmental benefits between to recycle and not to do it. The result shows that the total energy gain, resulting from the recycling of waste fractions, lands at 6 990 089 MJ, corresponding to drive 3 times around the Equator with a truck (40 t). The result shows that recycling 3040 kg paper provides an energy gain of (38 600 MJ) compared with burning paper (19 500 MJ) is 19 100 MJ, which corresponds to heat a house for 11 weeks.

This thesis within the field of Integrated Product development at the Royal Insitute ofTechnology, performed at Primary Development Dishcare at AB Electrolux, is supposed to finda solution to enhance the hygiene inside an Electrolux dishwasher. The outcomes of this thesisare functional prototypes to evaluate the efficiency of disinfection by the use of Ultra VioletLight and Ozone.The thesis has followed Electrolux Primary Development process, with delivarables andcheckpoints.Ultra violett light with a wavelength of around 264 nm penetrates through the cell wall ofbacteria and micro organisms and causes a molecular rearrangement of the cells DNA. Thisprevent the bacteria from reproducing and it is considered dead. Commonly used UV-C lampstransmits the wavelength 254 nm which is very close to the optimum for germicidal action.A competitive brand have reacently launched a dishwasher claiming to achieve greaterdisinfection with an UV feature. This dishwasher was tested during the thesis and proven tohave a very low effect on the hygienic result.Two prototypes were devolped and tested for UV disinfection of dishware.

Pålagt skratt är något som har använts i hela tevens historia och används än idag. Från början fick man inspirationen från radions tidiga dagar då man ofta spelade in sina program eller shower framför en publik. Det pålagda skrattet har funnits i din teveapparat i nästan 70 år, men i din radio hör du det aldrig. Varför inte det? Mitt examensarbete syftar till att göra ett humorprogram i radio med pålagt skratt och undersöka vad folk tycker om detta grepp i radio.

Climate and environmental issues is now high on the agenda. We live in a generation that must try to solve some major environmental problems. Buildings and habitations account for approximately 40 % of Sweden's total energy today. To reduce this figure, as needed, more research in the field of energy efficiency is required.This thesis concerns the heating of buildings. The load on district heating is heavy during certain times of the day.

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..

Idag ställs stora krav på företag att vara miljömedvetna och resurseffektiva i sin verksamhet. Vid mjukpapperstillverkning används stora energimängder och inom industrin har det under många år funnits en strävan att energieffektivisera processer och att tillvarata spillenergi, bland annat genom värmeåtervinning. Valmet Tissue Technology Center i Karlstad har idag en pilotmaskinen utan värmeåtervinningssystem. Den här undersökningen gjordes i syfte att ta reda på hur stor återvinningspotentialen är för värmeväxling i pilotmaskinens torkpartier, bestående av Yankeekåpan och TAD-cylindrarna. Tre maskinkoncept undersöktes: DCT®, NTT? och TAD.

The popularity of vegetated, or green roofs, has grown over the past years due to their potential function of maintaining urban environment quality. The aim of this study was to investigate if substrates with different organic material, peat and charcoal, with two contents (3 or 6 weight%) influenced the growth of the cuttings during the first critical period of the establishment. Biochar is used as amendment to agricultural soils and has, theoretically, many of the properties suitable as organic content in green roof-substrates. Peat is one of the materials that is commercially used in green roof industry. The substrate has been treated with different amounts of water.

The mining industry, in terms of ore excavation and metal production, is and has been important to the Swedish economy. In connection with the ore excavation process, large amounts of partly sulphidic waste are produced. When the metal sulphides are exposed to air and water they are eventually oxidised, which leads to the formation of acidic water with high concentrations of metal cations and sulphate ions, so called Acid Mine Drainage (AMD). This water may reach the nearest surroundings and cause negative environmental effects. By covering the waste with soil or water, the oxidation process can be minimised. At the Rävlidmyran mine in the county of Västerbotten open pit mining took place between 1951 and 1991.

The euthropthication of the Baltic Sea is a threat that is beginning to be taken seriously by the governments concerned. In Sweden, regulations concerning the allowed nitrogen (N) concentration in the effluent water from wastewater treatment plants are being tightened up. The Rimbo wastewater treatment plant has been imposed to reduce the annual mean concentration of total N in the effluent water to levels below 15 mg l-1. A more and more common way to reduce the nitrogen level in wastewater is to let the water pass through a wetland. This study investigates the possibility to build this kind of wetland at the outlet of the Rimbo wastewater treatment plant.A prestudy of the topography, soil characteristics and groundwater flow indicates that the land area in question is well suited for the construction of a wetland.

Antifouling paint containing the biocide bisTributyltinoxide (TBTO) has been used since1960 to reduce the occurrence of fouling on hulls on boats/ships. January 1st, 2003 theantifouling paints containing TBTO were prohibited. This ban covered all use of paintcontaining the substance TBTO. The ban was introduced because of alarming observationssuch as development of imposex in aquatic non-target organisms. Imposex is the impositionof male sexual characteristics on mainly female marine snails and occurs due to exposure toTributyltin (TBT).

With the climate change issues growing in importance on the social agenda, the field of urban masterplanning is of no exception when it comes to minimizing the carbon footprint in a variety of projects. The aim of this thesis has been to prepare the Carbon Critical Masterplanning tool, a software plugin for carbon dioxide emissions assessment developed by Atkins, to be used in Swedish conditions. The main targets were to improve the areas of the tool associated with energy conversion and renewable energy sources, and to test the tool in a real case. A planned construction of a new campus in Albano, Stockholm was chosen for the pilot study. A 3D model was built in the tool and the carbon footprint was calculated for a variety of combinations for energy supply to the future area.

The study was carried out by an activity with participant observation and feedback interviews afterwards. The result shows that the possibilities to physics are many in preschool. The children expressed new thoughts and ideas who concern other phenomena in physics during the investigation and discussed similar experiments and material to examine.

The energy consumption continues to increase as the use of electronics and energy consuming equipment increases. The use of fossil fuels has to be phased out for this to be sustainable in the long run while the use of renewable energy continues to increase. A renewable energy source is solar energy but the production of heat and electricity are today very expensive compared to other energy sources and an important task for the solar energy market to grow is therefore to minimize the production cost of the solar collectors while increasing its efficiency to produce heat and/or electricity. One way to convert solar energy into heat is by using solar collectors and electricity can be produced by utilizing the produced heat, or by applying solar cells.This thesis aims to recommend a reflective material for the next generation solar collectors from Absolicon and to recommend a commercially available coating for the receiver tube of the solar collector. A market study has been carried out to investigate the cost-related aspects along with the optical and durable aspects for the optical material of the solar collector.
