The topic of this essay is whether the private owned ammunition factory Norma Projectile AB was a part of a war economy system from 1938 to 1943. This is done by analyzing specific documents from the company´s archives that expose the connection with Swedish authorities. The selection and analysis of these documents are based on four main criteria?s of the concept war economy. These criteria?s are based on Ivan T.
En grundläggande modell för att beskriva stadens ljudbild med utgångspunkt i dess rytm
The purpose of this essay is to state a fundamental model which can describe the sounds of the city, emphasizing on its rhythm. The essay is based on a theoretical study that deals with essential elements to describe a soundscape. The theories presented are founded on R. Murray Schafer's theses about soundscapes, Bert De Coensels theses about rhythmical sound patterns and Ambjörn Hugardts view on rhythm. The model that is presented stresses the importance of a multidisciplinary perspective when one attempts to understand and describe a soundscape.
Investigation of yeast Grown in SSF Dring Biothanol Production from Lignocellusosic Material
Ethanol produced from lignocellulosic biomass has the potential to become a promisingalternative to gasoline. In this work the simultaneous saccharification and fermentation (SSF)technology was applied for ethanol production from hardwood with focus on cell growth,ethanol production and contamination.The SSF was performed at PH 5.5 and 35°C for different suspended solid concentrations(8%, 10% and 12%) of pretreated birch slurry which contained 16 % total suspended solids.Two different hexose fermenting yeast strain (Ethanol Red) and pentose fermenting yeaststrain were used.Quantifying the concentration of chemical components and metabolites in the fermentationmedium demonstrated that glucose and xylose are the major fermentable sugars in the slurry.The higher load of slurry (12%) represents a higher content of carbohydrates and potentiallyhigher end concentration of ethanol. Moreover, more lactic acid is produced with the lowerload of slurry (8 % or 10 %), presumably due to a result of a less inhibitory environment forbacterial growth. In this context, acetic acid sticks out as the most important inhibitor withconcentrations of 15.2 and 12.5 and 9.7 g/l respectively in the 12 %, 10 % and 8 % (ofsuspended solids) trials. Using pentose fermenting yeast may lead to higher ethanolproduction, lower xylose uptake and lower lactic acid formation.
Förutsättningar för småskalig solelproduktion i Australien
The study aims to investigate the feasibility of small-scale electricity production with solar electricity systems, also known as PV (photovoltaic) systems, in Australia. Due to the global warming, sustainable energy has in recent years become an increasingly important issue, both internationally and in Australia. With one of the largest dependencies on fossil energy sources in the world, the country's abundant solar radiation is a possible solution to this issue.Both the technical and the economic feasibility of small-scale PV systems were investigated. On the technological side, the electricity generation, distribution and consumption systems were studied. On the economical side, the parameters that drive the profitability of a PV investment were investigated.
Thymidinkinas 1 som tumörmarkör vid juvertumörer hos tik :
Determination of serum thymidine kinase 1 (TK-1) activity is used as a tumour
marker in both human and veterinary medicine. TK-1 is an intracellular enzyme
involved in a salvage pathway of DNA synthesis. The expression of TK-1 is cell
cycle dependent and the activity increases markedly after the G1 to S transition in
the cell cycle and then declines rapidly in G2. The pronounced proliferative
activity in tumour cells result in a higher TK-1 enzyme activity within the cell.
The fact that the increased TK-1 activity can be measured in serum makes TK-1 a
useful marker in diagnostics of neoplastic diseases and it provides information
regarding prognosis and treatment effectiveness. In human medicine a radioactive
based test is used to determine the TK-1 serum activity.
Åtgärder för att skapa säkrare hämtning och lämning vid skola : Undersökning vid Ludvigsbergsskolan i Valbo
Researchers, planners, and government agencies agree that road safety for children must be a priority and in particular that children should have a safe and secure way to travel to and from school regardless of age or the distance travelled. In Sweden, child traffic safety is a key part of the country?s Nollvision, a long-term traffic policy goal of ?no deaths or serious injuries?. Unfortunately, many countries have recorded increases in child traffic accidents as the percentage of parents who drive their children to school and thus congestion around schools has increased. Common strategies include traffic safety education for children, the redesign and improvement of traffic infrastructure, bicycle training, and carpooling.This thesis assesses the traffic problem around Ludvigsberg School in the district Valbo in Gävle, Sweden.
Klassisk medieanalys - nytt medium : En semiotisk analys av fyra tv-spel
I ett försök av mig att ge spelmediet samma sorts behandling som många andra medier före det har jag valt ut fyra spel inom två olika genrer för en analys av deras handling, karaktärer, estetik och gameplay. Handlingen summeras enligt reglerna för narrativt berättande och en semiotisk infallsvinkel används sedan för att leta efter saker, tecken, som är värda att tas upp för analys i alla fyra kategorierna. Vissa jämförelser görs mellan spelen, främst inom kategorierna estetik och gameplay, först inom samma genre och sedan genrerna emellan för hitta likheter och skillnader i sättet spelutvecklarna har valt att utmana spelaren och göra spelen roliga att spela och hur de har valt att förmedla spelens handling. De utvalda spelen är Capcoms Devil May Cry 3: Dante?s Awakening, Sony Computer Entertainment Americas God of War, Konamis Metal Gear Solid 2: Sons of Liberty och Ubisofts Splinter Cell: Chaos Theory.
Branding in Trade Unions - case of Unionen
Trade Unions are finding it increasingly challenging to appeal to employees and all trade unions alike are encountering new challenges to attract and retain members. Additionally a more diversified and educated labor market is creating demands for trade unions to better meet individual needs. The purpose of this study was to explore and analyze the role of branding in Unionen, the largest white-collar trade union in Sweden, and how branding efforts help in attracting and retaining trade union members. The theoretical foundation of this thesis is based on theories related to corporate branding and relationship marketing. Furthermore, the study develops and introduces the concept of member branding in the context of trade unions.
Verksamhetsstyrning: Utrikesdepartementets personalbostäder
The purpose of this thesis is to find means of control that secure cost efficiency regarding the accommodation for the employees on missions abroad of the Swedish Ministry for Foreign Affairs. Today the ministry?s cost for the employees? rented housing is 100 million SEK and there is a need of improvement in the control of these costs. A work method for organizational development will be used in order to reach the findings presented in the thesis. First we study the strengths and weaknesses in today?s control system.
Det obligatoriska skolväsendets pedagogiska strategier i arbetet med elever som har AD/HD. : Pedagoger i en integrerad respektive segregerad undervisningsform berättar och beskriver
The survey aims to highlight and describe how the schools' teaching strategies look like in the work of pupils from the neuropsychiatric disability AD/HD (Attention Deficit / Hyperactivity Disorder). The pedagogical strategies have been investigated in an integrated and segregated teaching method. The study is qualitative in nature where the interviews conducted, first with a student who has been diagnosed AD/HD but also with teachers from each school who is well versed in student teaching and work. The results of the study show that knowledge and commitment about AD/HD is crucial to students' role and function in school. If knowledge and commitment is sufficient for the student teaching tailored to student needs and the risk of misunderstandings occur decreases. Security is a key factor for students who have been diagnosed AD/HD and learning form in itself is no guarantee that students will feel safe. Students have in the two teaching methods stressed that they feel safe at school and with their education and therefore has no teaching method preferred.
Kostråd till föräldrar vid introduktion av fast föda till spädbarn : BVC-sjuksköterskans erfarenheter - en pilotstudie
BVC-sjuksköterskan möter många föräldrar som har frågor om kostintroduktion till spädbarn, en av BVC- sjuksköterskans uppgifter är att undervisa föräldrar i kostfrågor. Studier har visat att föräldrar upplever att de får olika råd från BVC-sjuksköterskor, vilket kan göra föräldrarna osäkra på vilka råd de ska följa. Syftet med pilotstudien var att beskriva BVC-sjuksköterskans erfarenheter av att ge kostråd till föräldrar vid introduktion av fast föda till spädbarn. Fyra intervjuer genomfördes med BVC-sjuksköterskor inom barnhälsovården i Region Halland. Kvalitativ innehållsanalys användes som analysmetod.
Frystorkning Kontrollerad torkning av kulturhistorisk dräkt?
Cultural objects may become wet by deliberate water cleaning, water disaster or watersoaked for other reasons. Air drying textile objects and even other organic materials from awater wet state, involves many problems depending on the strong capillarity action of water.Damages and changes such as bleeding of dyes, stains or lines of impurities from watermovement, shrinking or stiffness can occur. Freeze-drying as an alternative drying methodhas often been used for wet archaeological and marine objects, but more seldom for historicalmaterials.This bachelor thesis addresses the issue of whether freeze-drying can be an alternative controlleddrying method for historic costumes. Costumes and related objects are often compositeobjects, consisting of multiple materials, as well as being three dimensional, all of whichwill complicate drying. The purpose of this study was to investigate whether it is possible tohandle costume objects after wet cleaning for drying by freeze-drying, and if damages due tosurface tension of water, can be avoided in this way.
Enhetstestning: Kostnad mot kvalitet
Unit testing is a type of testing technique which is becoming quite fashionable to the developers and companies that are in the business of creating and managing software. Alas there are seldom any concrete data to support the positive claims of the authors in unit testing methodology books. These claims are instead based on empirical studies and the experience of the authors. The problem that arises from this situation is that it becomes problematic for managers and also the developers themselves to convince both customers and their own management to use this type of testing as there is no exact return of investment model. This essay examines this problem from two points, the first point is from the literature itself and interviews conducted with a number of developers at a software company located in Umea, Sweden.
Att reducera ledtiden i en produktion med hög variation och låg volym - En casestudie på Lab.gruppen
Due to increasing product availability and higher demands on fast deliveries, the competition between companies is growing. To be able to satisfy the customers? requests an efficient logistics system with short throughput time is required. By using tools associated with Lean production companies are able to make great improvements in their manufacturing systems and reduce lead times to satisfy customer demands.There are two classifications associated with manufacturing, high variety and low volume (HVLV) and low volume and high variety (LVHV). The general belief is that the concept of Lean production is difficult to implement in a production environment with high variety and low volume due to the concept being adapted to mass production.
Minoritetsproblem i Östeuropa : EU:s relation till Slovakien
The aim of this thesis is to study the situation of minorities in Slovakia before and after the EU-membership and if EU has played a role in the situation. Also the criteria for becoming a member and other treaties regarding protection of minorities between European institutions and the accession/member states are studied. With the help of i.e. literature, relevant internet pages and yearly studies of EU, the conclusion has been made that Slovakia has made an immense change in the state?s legislation when it comes to minorities and their fundamental rights, but that changes need to be made in attitudes as well.
