Vertikal förtätning : En del av ett hållbart stadsbyggande?

This is an essay concerning the density of the city. An increasing amount of today?s cities have a shortage of space available for the erection of new buildings and settlements, especially in areas close to the city-centre. New buildings and settlements are therefore often found in the outskirts of the city, resulting in long distances between work and living for many people. These long distances are a waste of limited resources and are inconsistent with the vision of the sustainable city.The challenge for the future is to insert new buildings and settlements in the existing city-structure and in this way reduce the distances between different city-functions.The density of the city can be increased in two different ways; by inserting new buildings between existing ones or by extension existing buildings, for example by an additional floor.

Project Inti : Produktutveckling av en solugn

In this report the two authors, and project contributors alike, describe their work withdeveloping a solar cooker intended for usage in the developing countries of the world.Specifically, the work aims at developing a new, solar heat driven cooking device, possiblybased upon the current product. This should, in comparison to the current product, be lighter,easier to transport and to produce. Also, the new product?s production mustn?t be more costlythan today and the included materials and components must be obtainable from within theBolivian national borders where the product is currently produced. During the project, certainadvantages with a more efficient, and, above all, a more moderately priced product, werediscovered.

Effektiv Planering enligt Lean Production : En fallstudie på Sandvik Mining and Construction

Due to a constantly increasing competitive pressure it is of great importance to constantly strive for improvements in order to gain competitive advantages. Lean Production is a concept that has been introduced with the aim to minimize waste and increase profitability. The purpose of this report is therefore to investigate how to perform effective planning according to the principles of Lean Production, in companys with customer exclusive products, through a case study at Sandvik Mining and Construction (SMC), and to investigate how SMC kan improve their planning of drifting rods at the production unit in Sandviken.The study started by creating a theoretical framework, to describe the subject planning and planning based on Lean Production. This frame work constituted the base for the case study which took place at Sandvik Mining and Construction, and also for the model and planning tool that has been introduced.The result of the study is partly a general model with factors that contribute to a more effective planning. These factors has beed identifed as SMED, which focuses on reducing set up times and in the end to facilitate the planning.

The importance of shade for dairy cattle in Sweden.

Today, there are no regulations saying that cows must have access to some kind of shelter at pasture during the summer. In more tropical countries, it is well-known that dairy cows might suffer from heat stress when exposed to sun and high temperatures. The well-being of the cows is thereby reduced and the production may also decrease. In Sweden, no research has been done in the area and therefore it is now a clear need of improved knowledge.The purpose of this study was to investigate the importance of shade for dairy cows in Sweden. The behaviour of 30 cows was examined to see any differences between cows with access to shade and cows without access to shade.

Jämförande undersökning av värmeåtervinning ur frånluft i två flerbostadshus med frånluftvärmepumpar

Två olika värmesystem i två flerbostadshus har analyserats. Målet med analysen är att få en uppfattning om vilket värmesystem som är mest fördelaktigt i flerbostadshus. I analysen jämförs två olika värmesystem. I värmesystemen används två olika sorters frånluftsvärmepumpar för att återvinna värme ur frånluften. När värmepumparna inte klarar av att producera tillräckligt med värme för att täcka fastighetens värmebehov används fjärrvärme som spetsning.

Wobblerpump

The task was to design and manufacture a submersible displacement pump working with the wobble plate principle. The main task for the Wobble plate pump is to be used as a sewage pump for smaller households or dewatering pump in environments where small flows and high pressures are acquired. For these purposes ITT Flygt sell a screw pump, PC-Grinder 3068. The hydraulic part of the PC-Grinder is manufactured by a subcontractor. Therefore ITT Flygt wants to evaluate an alternative to their screwpump PC-Grinder, which can be entirely manufactured by them self.

Döden och livet därefter enligt en berättelse om liemannen : En kvalitativ undersökning av uppfattningar om döden och livet efter detta i Grim Fandango Remastered.

The purpose of this paper consists of examining the different ways of thinking about death and life beyond death conveyed in the game Grim Fandango Remastered. This was done by using a theoretical framework consisting of a self invented definition of death called "Bodily death". This definition consists of common notions about death such as cessation of life functions like movement, metabolism, respiration and overall cessation of brain functions. It also included cessation of vital processes, which includes the ability to make energy transfer, making reparations, for example by cell replication, as well as the waste system of the body.  Besides this, the study examines the prevalence of dualism, a conception that views the soul essential to the individual's mental state. Two kinds of dualism were investigated, simple dualism with the assumption that the individual is made up of the soul, and compound dualism, where soul and body are dependent on each other for the survival of the individual.

Fermented sausage : product development at Lindell's Gårdsslakteri

Product development is a risky business; many products never yield profit, but it is also ne-cessary for a company?s survival in a competitive business where the costumers change their requests constantly. Consumer-led product development is developed from the wish to fill the consumer?s needs and expectations and thereby be more likely to succeed. Lindell?s Gårdsslakteri AB is a local slaughter and meat processor in Västergötland.

Svåra samtal? Hur sköterskor på barnavårdscentraler samtalar med föräldrar till överviktiga barn : En intervjustudie

AbstractThis degree project is about having meetings in The Swedish Social Insurance Agency, which is awide organisation. This work will concentrate on one of the projects going on within theorganisation which is travel-free meetings, where they are building a video meeting system thatallows the employees in the organisation to be able to meet with each other through the use ofvideoconferencing instead of physical meetings.In this work we will show how Kaikaku (radical system changes) along with Kaizen (continuouschange) can support an organisation to become more efficient and reduce wastage. We have donethis work in an organisation that is present in over one hundred locations in Sweden.The Social Insurance Agency has over 13 000 employees at over one hundred locations inSweden.The organisation has to be close to their customers and provide the best service aspossible. To be able to work in a uniform way, the employees get together and have meetings.Some meetings are just progress meetings and takes perhaps no more than two hours to complete.However, if seven employees from seven different locations need to have meetings, in the worstcase, they all have to meet in a common place.This is expensive for the organisation in travel costs, time and absence from work, but thetravelling also contributes to environmental pollution if the employees are travelling by a fuelpoweredvehicle.A whole day could go lost for having a meeting in about two hours if all sevenemployees went from their own cities to e.g. Stockholm for the meeting.Muda (wastage) of travel created several different types of Muda, namely:? Wastage with anticipation when the employees had to wait for e.g.

Yrkesroll i förändring? : En studie av ett antal statsanställda arkivariers upplevelser av införandet av en verksamhetsbaserad arkivredovisning

The aim of this thesis is to examine the archivist's professional role in public authorities and discuss if, and in what way, the profession is effected by the new swedish process oriented archival description system. The study focuses on swedish authorities and does not make any international comparisons with other institutions. Neither does it investigate archivists workingin the private sector, but centers on public institutions.The survey is performed in five swedish public authorities, using interviews and observations. Grounded theory is used as a method initially in the purpose of keeping an open mark towards the object of study. The initial results led on to questions about how well the archivists perceived that communication within the authorities served, and how this in turn prepossessed their work situation and the professional roles in which they found themselves.

Förpackning med förbättrad miljö- och säljaspekt : Ett projekt i samarbete med Primus Sverige AB

This work of examination describes an environmentally oriented product development aimed to develop new packaging with improved environmental and sale aspects of the products from Primus Sweden AB. The report covers the design process from the first collection of facts to the final results with a description of all methods involved in the work. The focus has been on a clear environmental awareness and the report contains a deepening of the concept life cycle assessment (LCA) for product development. In the process, the consumers? opinions of the brand Primus and environmental profiling formed the basis for the packaging to communicate the right values such as quality, technology, environmental awareness and adventurer?s first choice.The deepening of the life cycle analysis shows that composting and other alternative treatment of the biological cycle is not possible to implement in a satisfactory way in the design process.The work results in two final concepts.

Varför personalekonomi?

Chapter 6 of the Ch?ndogya Upani?ad has often been treated in works on early Indian philosophy, as well as in some comparative studies on color symbolism. Attempts to place it in a larger framework against the background of late Vedic religion are, however, few, the rationalistic and ?tradition-challenging? appearance of the text having repeatedly been emphasized. But the doctrine contained in the text ? a cosmologic teaching on the three elements constituting the universe, each being characterized by a color (red, white, black) ? and their microcosmic counterparts in the human body, does have some clear affinities to the worldview of the Br?hma?as and ?ra?yakas, which posits a series of similar correlations (bandhu-) between macro- and microcosmos.

Betydande faktorer för effektiva specialtransporter

För att vara konkurrenskraftig på marknaden behöver företag hitta och använda möjliga resurser för förbättringar. En grund för ett kostnadseffektivt och kundtillgängligt logistiksystem är transporter. Det är viktigt att ha fokus på både interna och externa transporter när processer ska optimeras och via detta erhålla lägre kostnader. Den enskilt största logistikkostnaden i många företag är transportkostnaden. Studien har utförts på ett företag som är verksamma inom industrin. Fallstudieföretaget har ett fokusområde inom transporter, där syftet är att utveckla verksamheten inom specialtransporter.

Extraktion av polyfenoler från pressrester av röda vindruvor

Antioxidanter är kemiska ämnen som är kapabla till att förhindra oxidation av andra molekyler. Dessa ämnen återfinns i djur- och växtriket och tycks ha en skyddande effekt på cellvävnad genom att motverka skadliga oxidativa reaktioner. Antioxidanter används bland annat industriellt som tillsater i livsmedel och andra produkter i syfte att förhindra oxidativ degradering och bibehålla näringsvärdet i livsmedel. I vindruvor återfinns höga koncentrationer av naturliga antioxidanter, främst i form av fenoliska ämnen. På grund av att vinindustrin bidrar till stora mänger avfall, främst i form av druvrester, är det önskevärt att hitta en effektiv metod för att återvinna fenoliska antioxidanter från avfallet.I detta arbete användes lösningsmedel-extraktion för att extrahera fenoliska ämnen från pressrester av röda vindruvor av varianten Tempranillo.
