Active headsets have been on the market for years and now it is time for something else to enter the stage. The technology of active noise Reduction can for exmple also be used in ventilation systems for reducing ventilation noise. An active control system principally consists of four important components, namely the downstream error microphone, the upstream detection or reference microphone, the digital signal processor (DSP) and a loudspeaker. The upstream reference microphone listen to the primary ventilation noise and sends it to the DSP which makes a phase shift to the signal and sends it to the loudspeaker. The loudspeaker sends out the opposite waveform of the incoming one and reduce the primary ventilation noise.

The Income Tax Act is enacted what criteria must be met to obtain a tax Reduction of household work. Household work is the common term for ROT- and RUT-works. The purpose of the tax Reduction is to increase job opportunities and to discourage that undocumented work performs.It is only for the labor cost as tax Reduction is given for. The concept of labor cost is defined in law as it is not comprised of cost of materials, equipment or travel. The preliminary work provides no closer explanation what the labor cost includes.

GE Healthcare operates in Uppsala (Sweden) and develops systems, equipments and medium to purify medical substances. Discussions with the local authority concerning planed far-reaching changes and upgrades of the biological process techniques for sewage management, aroused the question about revising the terms of permit for the activity. Therefore it seemed necessary to evaluate a newly installed biological process technique, which is the background of this thesis. The evaluated biological treatment process was built in 2003 and consists of a biological reactor filled with moving bed carriers with a high surface area for biological growth. At the time of the project the biological wastewater treatment plant consisted of a flow equalization facility and two following parallel biological processes; a biological reactor with moving bed carriers and a tower trickling filter.The aim of this thesis was to survey the function of the biological reactor with respect to the Reduction of organic matter.

In 2007 the Swedish government appointed a commission of inquiry with the task to submit a proposal of Reduction in the requirement of a minimum legal capital for private limited liability companies. The commission of inquiry?s main proposal involved a Reduction to SEK 50,000 compared to the prevailing SEK 100,000. Following a complementary proposal from the Justice Department suggesting a Reduction to SEK 1, this paper aims at providing an understanding of the function and purpose of a minimum legal capital and the consequences that follows from an abolition of the statutory capital requirement. The thesis concludes that the legal capital?s main purpose is that of a standard contract internalizing the shareholder?s risk in business.

This thesis describes how a cost Reduction project was done on the Packsize ondemand packing machine EM7. The cost Reduction was achieved by making minorredesigns of the EM7.The project began by studying the EM7´s structure and function by working on itsassembly line. A short literature study on the subject Design for Manufacturing wasalso done.By working on the assembly line and by speaking with staff from production anddevelopment departments, a number of ideas for reducing manufacturing costs arose.Estimations of the potential cost Reduction size for each proposal were done incollaboration with vendors and the purchasing department. Based on the size of the cost Reduction, technical risk, impact on the assembly lineand the development time the various proposals were ranked. The two highestranked proposals were selected for further development towards finished solutions.One of the ideas that were selected to develop in to a finished solution meant thatsome of the pneumatic valves were replaced with others.

A water treatment unit consisting of two aeration basins, two settling tanks, a residence basinand a horizontal subsurface flow wetland were used to treat wastewater from an eggprocessing factory in Brazil. The aim of this paper was to determine the efficiency of thesystem in reducing nitrogen, phosphorus, BOD5 and TSS (among other parameters) andgetting a further understanding on different kinds of constructed treatment wetlands as well astheir nitrogen and phosphorus removal processes. The wastewater from the factory consistedof process water from manufacturing and water used for cleaning, no stormwater or sewagewater entered the system. Tests were taken three times a month from October 2013 ?til April2014.

Syfte: Syftet med vår uppsats är att belysa den etiska dimensionen av harm Reductionanknuten missbrukarvård. Till vår hjälp har vi haft etiska teorier och sociologen Zygmunt Baumans begrepp. Frågeställningar: Vi har använt oss av två huvudfrågor som vi därunder bryter ner i konkreta frågor. 1 Hur ser de etiska resonemangen ut hos personal verksam inom harm Reductionanknuten missbrukarvård?Vilken typ av etik använder de sig av? Har de centrala etiska principer, vilka? Hur ser de på etik och moral? Följer de etiskt formulerade regler? Hur ser de på prohibition? Hur ser de på drogbruk? Hur ser de på människan? Vad driver dem i deras arbete? Hur ser de på harm Reductions påverkan på samhället?2 Hur kan man förstå harm Reductionmetoders framväxt ur Baumans sociologiska perspektiv?Hur kan harm Reductionmetoder kopplas till det senmoderna samhället? Hur kan harm Reduction rättfärdigas etiskt utifrån ett sociologiskt perspektiv? Hur kan harm Reductions förklarar sociologiskt? Vilka förutsättningar fanns för att harm Reduction skulle kunna utvecklas? Hur kan Baumans begrepp förklara harm Reductions ställning i det senmoderna samhället? Metod: Vi har använt oss av en kvalitativ metod med intervjuer som redskap.

The general consensus is that the gap between the Swedish variable mortgage rate and the repo rate has increased over the last years. Although the Riksbank in recent times has cut its base rate, many banks have chosen either to leave the interest rate on variable mortgages unchanged, or they did reduce it but by less points than the Reduction in the repo rate. The linear relationship between the repo rate and the variable mortgage rate has changed over the last decade and the mortgage margins these days are relatively high. This can somewhat be explained by the new rules introduced in the bank sector requiring banks to increase liquidity and equity. Since mortgage loans play an important role in banks? lending business it is of interest to gain knowledge in whether a repo rate Reduction latterly has generated a limited affect on the banks lending rates..

This paper deals with the opportunities for the technique of condensation, for wood fired household heaters, on the Swedish market. In this project the condenser is preceded by a scrubber and both energy exchange and separation of unburnt particles have been studied. The facility studied is connected to a wood stove at 30 kW. The tests would show that the effect from the stove never reached above 16 kW. This might be a result of the low temperature of the water going into the stove, from the condenser. In addition to this the wood was not of highest quality and the stove could have needed some maintenance before the tests.

Treatment wetlands been showed efficient for reducing pollutant in waste water. In Lajeado ? RS, Brazil the landfill has poor leachate water treatment. It is necessary to supplement the treatment plant because they need to reduce BOD, COD and nitrate of the water going to recipient. A subsurface flow wetland (SSF) can be a good choice.  In order to be able to design an efficient SSF it is important to understand how the grain sizes of a substrate affect the reducing of pollutants in waste water.

Denna uppsats behandlar ett antal stigmatiserade individers möjligheter att återinträda i samhällsgemenskapen efter ett liv i missbruk eller på institution. Detta har skildrats genom individernas livsresa, från inspärrning/inskrivning på totala institutioner till det vakuum som uppstår när de blivit frisläppta eller utskrivna, och vad de därefter har för möjligheter att förändra sin identitet och bli en del av samhällsgemenskapen. Vi har inriktat oss på en verksamhet, som fångar upp personer i ett mellanläge, efter inspärrning men före samhällsintegrering. Verksamheten har till skillnad från statliga behandlingsverksamheter en acceptans för Harm Reduction. I tidigare forskning har vi beskrivit missbruksvården och den svenska narkotikapolitiken.

Today it is common to spray against most weeds by using very expensive weed-killers. The goal for every farmer is to have as low costs as possible for their use of machines and weed-killers. Therefore it is in everyones interest to find other methods to fight the weeds. Finding a way to reduce the rise and growth of weeds already at the preparation of the soil would lower the number of laps over the field and also decrease the amount of weed-killing dose. Tests show that by harrow in the dark it is possible to reduce the population of weeds with up to 60%, but the normal Reduction would be about 20-30%. To verify the results above we made tests by using two different methods of preparing the soil. We tested ploughing and harrowing in daylight and during night. Later we checked the number of different weeds in areas prepared in daylight and during night. By studying the results from the different methods used we found a considerable Reduction of some kinds of weeds in areas prepared during night..

Companies that invest in e-learning have different expectations regarding the outcome of the investment. According to literature and articles it is common that companies see Reduction of costs as the primary benefit with e-learning. Therefore we ask ourselves the question if companies have attained the expected benefit of the investment in e-learning and to what extent cost Reduction have been a determining factor in the investments? The purpose of the thesis is to examine if companies that invest in e-learning have attained the expected benefits. We also want to examine what the reason for investing in e-learning is and if cost Reduction is the primary reason for investing.

This report is a result of a degree thesis at Luleå University of Technology together with Stram AB in Växjö. The project aimed to develop a size reducible bed, that gets small when folded and has a new slim design. The development of the new folding bed had the purpose to give Stram AB new ideas of how guest beds can look like and be used in the future. Information about Stram´s products and also information of other similar products on the market was gathered. A visit at a store, internet and interviews gave grater insight of the market, and of customer needs.

The premise for this study is the question how we should relate to people with different religious beliefs. The aim is to examine if an existence characterized by a religious diversity should affect the certainty and confidence in our faith. To answer my question I have turned to the philosophers David Basinger, Mikael Stenmark, William Lane Craig and Robert McKims different views on this issue. Using an approach based on a comparative method and argument analysis I have then assessed their different opinions in the matter. Based on my own discussion of these arguments I conclude that a religious diversity should imply a Reduction in our own religious confidence and that it should be reduced in relation to the amount of disagreement that exist between conflicting religious perspectives in an specific case and matter.
