Rationell produktion av platsgjutna stommar för flerbostadshus
The purpose of this degree-project was to investigate the possibilities for primary air preheating into the two smallest waste incineration boilers of Halmstad Energy and Environment. The investigation is a pre-study which has the primary goal to evaluate technical and financial offers from companies that manufacture primary air preheater, and investigate if it is technically and financially profitable to do a purchase on primary air preheaters in the future.In the pre-study it is proposed that it is most efficient to have individual primary air preheater, one for each incineration boiler and the primary air are also proposed to be preheated by hot water in the pre-study. Further in the pre-study it is proposed that the heat-exchanger should have plain tubes instead of finned tubes, to avoid getting dirty fast. The space in the boiler-room is limited, and therefore the major problem was to fit in the primary air preheaters into the boiler-room. By comparing the different offers from the companies, the result in the pre-study shows that the offer from the company C.A.
Med för hög musikvolym hör du inte farten
Att tidsperceptionen är påverkbar har tidigare påvisats. Studien syftar till att undersöka huruvida tidsperceptionen påverkar fartperceptionen, med hypotesen att när interna taktgivaren går snabbare uppfattas farten som lägre. 28 försöksdeltagare fick under fyra betingelser (Lugn, Stressig, Egen musik och Tyst) utföra tids- och fartestimationer under bilfärd. Inga signifikanta resultat påvisades ifråga om vare sig tidsperceptionen eller dess inverkan på fartperceptionen. Däremot skilde sig prospektiv estimation av medelfart åt beroende på betingelsen.
Bachelor thesis Re : bottle
There is a new beverage container on the market, a bottle made out of pure aluminum as a replacement for the traditional container made out of glass. This new container has the potential to reduce both cost and pollution during transportation, the lighter and stronger construction has every advantage compared to the old one in glass. The new container has every possibility to make it on the market. Some of the biggest brands within the soft drink market already use these bottles in countries without any recycling demands like: Coca-Cola, Heineken and Pepsi. The only thing stopping these brands from the Swedish market is the lack of a functional return system, there is only one company that uses the bottle in Sweden today and they take care of their own used bottles.
Svenska entreprenörers etablering på en främmande marknad : En studie om strategiska val och kulturella svårigheter
Bakgrund: De senaste 60 åren har karaktäriserats av företags flytt till nya marknader. Sveriges integration med EU tillåter fri rörlighet av varor, tjänster och arbetskraft vilket har bidragit till att både stora och små företag har större valmöjligheter till vidare expansion. Svenska entreprenörer som startar sin verksamhet på marknader som är tydligt skilda från den egna till både avstånd och kultur blir en allt vanligare syn.Syfte: Syftet med denna studie är att identifiera de problem och viktiga faktorer att ta hänsyn till som uppstår vid en marknadsetablering i ett annat land för svenska entreprenörer. Vidare ämnar studien även undersöka varför svenska entreprenörer förflyttar alternativt startar sin verksamhet i utlandet.Slutsats och resultat: Viktiga faktorerna att ta hänsyn till för svenska entreprenörer som etablerar sig i Spanien verkar utifrån denna studie framförallt vara kulturskillnader, legala problem som uppkommer under etableringen samt vikten av relationer och nätverk vid affärsuppgörelser. Den primära anledningen till etablering i Spanien förefaller sig vara sociala skäl och inte de eventuella affärsmöjligheterna som finns..
Kakelugnar : en studie av Emil Petterssons kakelugnsmatriser
In recent centuries the Swedish Tiled Stove has varied in its design with an aesthetic evolutionary history that has not only followed the architectural and artistic ideals but also the taste in stove design. The heat source has varied depending on the regional traditions and where it was located within the country, but the inside of the construction was of a similar five channel system. The purpose of this paper is to study and compare the design of tile matrices made by Emil Petterson with other Swedish stoves. The following questions will be addressed:What characterized the production of a small scale tile stove workroom during the years 1900-50? Which main styles can be described as Emil Pettersson?s ideal while producing his matrices? And finally, is it possible to study the tile stove matrices as objects of historical and cultural significance, and what difficult methodological issues might occur in the doing of it? To answer these questions I will present the results of the documentation of Pettersson?s tile matrices with detailed historical categorizations and schedules. The conclusion shows that Pettersson as a stove builder and -producer was characterized by eclectic ideals and a design shape based on more liberal interpretations of contemporary trends.
Police Science - expansionen av ett kunskapsfält : En studie om vetenskapligt gränsdragningsarbete i 1930-talets Chicago
In 1929, the Scientific Crime Detection Laboratory was established in Chicago?the first of its kind in the United States. The purpose was to engage in practical use of scientific methods in the detection of crime. In 1930, the institute published its own periodical called The American Journal of Police Science. Applying the theory of boundary-work, this essay analyses how the novelty institute argued its legitimacy as a scientific establishment through the expansion of Police Science as a collective field of knowledge.
Healthier vegetables through temperature stress? : a review of Brassica oleracea
The objective of this report is to present a review of the studies which has been carried out up to days date concerning how temperature affects vegetables physiologically when it comes to their health inducing as well as quality reducing features. The essay therefore starts off with defining what is meant by the terms health promoting and quality reducing features. It then moves on to describe how different subspecies of Brassica oleracea, that is to say vegetables such as broccoli, cauliflower, Brussels sprouts and kale, is affected by temperature. B. oleracea was chosen because the species contains several commercially interesting subspecies and therefore provides a broad field even though only one species is assessed.
Design av utomhusträdgård i Dubai :
To plan and build a garden in Dubai has other conditions and challenges than what you experience in Sweden. The heat, wind and lack of water makes the need for durable plants, a good design and landscaping important if you want to have the opportunity to use your garden during most of the year. The soil is poor of nutrients, alkaline and sometimes saline, witch makes supplying the soil with organic material and various fertilizers necessary if you want to be able to plant a bigger range of plant material in your garden. Another important part is to provide your garden with a good irrigation system that should be put into the ground before planting so that the plants are given a more even irrigation.
It?s relatively green scenery you meet and to me it?s in a way surprising since the country with its climate is rather harsh for the purpose of supporting plant life.
Anpassningar vid etablering för snabbmatskedjor i Saudiarabien? : Svenska Max till den arabiska halvön
Vår allt mer globaliserade värld har medfört att alltfler svenska företag internationaliserar sin verksamhet till mer avlägsna områden. Ett av dessa svenska företag som nu står inför sin första utlandsexpansion är den svenska snabbmatskedjan Max AB. Max har valt att börja sin expansion i Saudiarabien, ett land långt ifrån Sverige, inte bara i termer av geografiskt avstånd utan även kulturellt avstånd. De kulturella skillnaderna som Max möter kan komma att påverka verksamheten och leda till att vissa anpassningar måste genomföras för en framgångsrik etablering. Uppsatsen undersöker det rådande förhållandet för snabbmatsbranschen i Saudiarabien och visar vilka anpassningar internationella snabbmatskedjor bör eller måste göra på grund av de kulturella skillnaderna de möter.
Energieffektivisering av industribelysning : Planering av belysningsanläggning i mekanisk verkstad
In Uppsala, Sweden, Vattenfall has a combined heat and power plant. On the premises there is an engineering workshop with old fluorescent and mercury lamps that need to be replaced. This provides a great opportunity to save energy and money by installing more efficient lighting. The main purpose of this study was to present two functional and energy efficient lighting systems including control system. The lighting systems were designed by investigating the working environment, measuring illuminance and by simulations in the software DIALux.
Energieffektivisering och solenergi i en universitetsbyggnad : Undervisningshuset och Biblioteket i Uppsala
Akademiska hus is a real estate company that specializes in providing Swedish universities with housing facilities for educational and research purposes. The company strives to reduce its use of energy by 40% between the years 2000 and 2025. The aim of this thesis is to determine which measures can be taken to reduce the need of purchased energy in a building that is used by theSwedishUniversityof Agricultural Sciences inUppsala.In order to determine the results of various changes to the building envelope and ventilation system, the building was modelled in the computer simulation program VIP-Energy. Other proposed changes to make the use of energy more efficient concerned water use and lighting. The need of purchased energy can also be reduced by producing electricity or heat on site, using solar energy.Results show that economically viable measures include upgrading windows and faucets, adjusting control systems for ventilation and lighting, and installing roof mounted solar panels for power production.
Kreditbedömning och revisorns betydelse : - ?Revisionskostnader är peanuts?
Syfte: Med start år 2009 genomförde den svenska regeringen flera åtgärder för att minska de administrativa kostnaderna för företagen, varpå revisionsplikten för mindre aktiebolag upphörde. Finansieringen för de mindre företagen är en viktig fråga för ekonomisk tillväxt i Sverige, och för att kunna utöka verksamheten krävs kapital. Det vanligaste i Sverige är att all expansion sker med lånade pengar. För dessa företag är det av yttersta vikt att kreditprövningen sker med stor aktsamhet för att undvika framtida förluster. Vi ställer oss därför frågande till hur den frivilliga revisionen påverkar företagets möjligheter till lån och i förlängningen den expansion som är viktig ur ett samhällsekonomiskt perspektiv.
Tilla?mpning och simulering av naturlig ventilation : Potential fo?r utnyttjande i kontorsrum
Mechanical ventilation is the most common type ofventilation in newly constructed office buildings. Therehas been an interest to utilize natural ventilationinstead of mechanical ventilation among architects andHVAC consultants in recent years. This is due to thesize of mechanical ventilation systems, which arespace consuming. The mechanical ventilation system isalso complex and requires maintenance. Furthermore,the fan uses a considerable amount of energy.
Capital Structures and Internationalisation
Abstract The internationalisation of a company is enabled by integration of markets. New markets mean new revenues, but also demand capital to finance the expansion. To bring in new capital may offer new possibilities but also higher debt-equity ratios, which affect how external interested parties value the company. This thesis, inspired by previous and mainly US based research, researches the debt-equity ratio of Swedish multinational and domestic companies, sampled from the Stockholm Stock Exchange. The research questions have focused on the impact of certain internationalisation variables on the debt-equity ratio; how does the debt-equity ratio differ between international and domestic companies? Can a difference be explained by the degree of internationalisation? Can a difference be better explained by the presence of international ownership? By measuring the concept internationalisation as both trade and presence, the questions were operationalised into four hypotheses.
Följdeffekter av olika användningssätt för vedråvara : en ekonomisk studie
Since the turn of the millennium a sharp increase in the interest for bio energy has been observed. Important reasons for this growing interest can be due to the fact that fossil fuels are a finite resource. A net discharge of greenhouse gases occur when fossil fuels are burned. The discharge of greenhouse gases are considered to be the main reason to the greenhouse effect. Means of control to increase the use of bio energy has been introduced and, as intended, the use of bio energy has increased.
As a result of the legal provisions the ability to pay for bio energy has increased, which the forest industry view as a problem.
