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.
Gammalt vin i nya läglar? Är PRS-initiativet endast en nydaning av tidigare strukturanpassningsprogram?
Abstract Denna studie har vi ägnat åt att undersöka PRS-dokumenten, vilka innefattas under IMF och Världsbankens nya skuldreduceringsprogram som ska präglas av nationellt ägande, nationellt drivande och landsspecificering. Frågan vi ställt oss är om dessa dokument är landsspecifika eller om de är mer generellt utformade och då ej så anpassade till det enskilda landets förhållanden. Vi har även tagit del av den kritik som riktas mot PRS-initiativet och försökt utröna hur pass befogad denna är. Kritikerna menar bl.a. att PRS-initiativet endast är en fortsättning på tidigare strukturanpassningsprogram (framtagna av IMF och Världsbanken) och inte alls något nytt inom utvecklingsarbetet.
Spädningsvätskans påverkan på vaginas mikrobiologiska normalflora hos sto i samband med insemination
Sheep breeding contributes not only with wool, hides, meat and milk but also with openlandscapes. The sheep?s wool is a good raw material thanks to a lot of different qualities as itis water rejecting and easy to form. The wool production today is concentrated to specificplaces in the world which leads to environmental problems and a distorted market. InJämtland, a province in Sweden, there is right now a staking going on for local production andrefining of wool in a project called Ullforum.

Peat litter is a soft material with high absorbency. About hundred years ago many farmers in Sweden used peat litter to their dairy cows. After the World War II the use of peat litter decreased and the farmers used more straw. Nowadays (year 2007), when it is harder to find straw and sawdust to buy, peat litter is advancing again. The purpose with this study is to investigate peat as a litter to dairy cows.
Har valet av mätmetod någon betydelse vid uppskattning av QALYs - en ekonometrisk analys baserad på longitudinell data från trafikskadade individer
En ekonometrisk paneldata modell användes för att studera hur antalet förlorade QALYs skiljer sig beroende på valet av mätmetod. Data baserades på individer som skadats i trafiken och som retrospektivt värderat sin hälsorelaterade livskvalitet direkt före olycksfallet och vid olika tidpunkter efter olycksfallet. Tre olika mätmetoder användes: VAS, IHQL, och EuroQol. Förlorade QALYs beräknades för fyra subgrupper. För subgruppen ?svårt skadade/fullt friska före olyckan? var antalet förlorade QALYs störst (0,370) respektive minst (0,130) om det uppmätts med EuroQol respektive IHQL (relativ skillnad var 2,85).
Regional tillväxt : En studie enligt Economics-base modellen
Denna uppsats använder branschvis sysselsättningsförändring i Sveriges 21 län mellan åren1995-2002 som ett mått på regional tillväxt. Alla branscher i ett län delas in enligt SNIsystemetsbranschklassificering. För varje bransch beräknas enligt Economic-base modellenen lokaliseringskoefficient som visar branschens sysselsättningsandel i länet i förhållande tilldess sysselsättningsandel i riket. Den bransch som i respektive län uppvisar högst värde påkoefficienten benämns basindustri. Sambandet mellan sysselsättningsförändringen i varje länsbasindustri och länets totala sysselsättningsförändring undersöks genom en paneldatastudie.Förutom basindustrins sysselsättningsförändring används den länsvisa befolkningsnivån somförklarande variabel.
Ekonomin under omläggningsåren vid övergång till kravgodkänd produktion :
The purpose of these theses is to show the financial economical situation during the change from conventional dairy production to ecological production. The thesis is accomplished by collecting information from literature and interviews where needed.
The target group of these theses is dairy producers who will transform their production from conventional dairy production to certified ecological dairy production. The theses emphasise on the economic situation during the adjustment years. For this I have studied a presently producing dairy farm.
Verk: Utan titel, text på papper : konstens betydelse för näringslivet
The paper's purpose has evolved during the process of researching and writing it. In the beginning it was to investigate if art and culture could increase the strength and knowledge of a brand and if there existed a knowledge about this amongst Swedish companies, situated in Stockholm. During the process the purpose has evolved into exploring the type of companies that acknowledge this and those that don't. By using Bourdieu's terminology and tools, the reasons behind the use of art has been analyzed.The paper employs an explorative approach by accessing data through interviews and public data provided by the Internet through web pages and government files.The paper comes to the conclusion that what Holt calls cultural branding has not evolved, when looking at the companies that are accurate for this study. Out of 24 companies only one comes close to observing socio cultural movements through the arts.
Den manuella kontanthanteringen : Beslutet av en oförändrad affärsstrategi
The work aims to problemize and increase the understanding for the new labour market's flexible organising. By using Elias and Scotson's theory, the new organisational form of hiring doctors in healthcare will exemplify the developments taking place with many temporary jobs and how it affects the intrinsic structure of a work to be studied. The essay will focus on examining how the interaction affected between established nurses and new temporary doctors given the new form. How the interaction of the recently established group possesses a higher social-, economic- and cultural capital than the already established working group? The method is a qualitative study with three long and deep semi-structured interviews.
Cykelsäkerhet för studenter : Studenters cykelsäkerhet mellan dagliga destinationer i Uppsala
Our thesis focus on how retirees perceive Tv4s news casts of economy news where we focused on five different aspects: What is the relationship between the news cast and the viewer and how does the viewer express their understanding of the news cast and the way it is constructed? What are the viewers attitude towards the news content and how do they find the news cast useful for them personally?We choosed retirees as our target group due to their vulnerable economic position in today?s society and TV as an important medium for them due to the digital divide. The study was performed with twelve qualitative interviews and one group interview where six retirees took part.We discovered a big interest for economic news in the target group. The majority had a sympathetic view of the news cast they saw but they also expressed skepticism toward the economy segment and/or news castings. The majority expressed a lack of trust for the journalists and the experts brought in to share observations and make announcements, and the financial business overall.
Interorganisatoriska interaktioner inom Inkubatorer : En studie om kunskapsutbyte och inkubatorsystem
BackgroundIncubators are important facilities for Economic growth in society. The main purpose of incubators is to accelerate knowledge intensive firms onto their market by both providing resources and an entrepreneurial environment.Problem Companies within incubators are encouraged to share knowledge and experience with each other with the goal to stimulate development and invention of new technology. This exchange involves interaction on an inter-personal and inter-organizational level. Incubators need to create an open and transparent environment in order to enable this exchange on both levels.Purpose The purpose of this study is to enhance the understanding of how knowledge and experience exchange occurs within the context of incubator systems. By understanding how incubators can capture knowledge and learn from the incubator process, this study can contribute by insights of how the incubator process can be further improved.Method This bachelor thesis is written from an abductive approach and is based on a qualitative case study of Ideon Innovation in Lund.
Driva tulpaner i näringslösning eller i jord :
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?.
EU:s gemensamma utrikes- och säkerhetspolitik - En studie om dess uppkomst och institutionella utformning
This thesis aims to explain the emergence of the Common Foreign and Security Policy of the European Union, and its institutional shaping, by using elements of Neofunctionalism and Liberal Intergovernmentalism.Using Neofunctionalism, the Common Foreign and Security Policy can be explained both as a side-effect of Europe's economic integration, and as a way to maintain the former and the European Union's position as an economic superpower. The institutional shaping is a result of lack of convergence between important national interests. Therefore it rests on a firm intergovernmental base, with rigorously limited use of supranational decision-making.For Liberal Intergovernmentalism, geopolitics and ideology, and to a certain level log-rolling, have played important roles. The reunification of Germany convinced France to form an alliance between the two countries. France, determined to achieve an economic and monetary union, thus offered Germany a political union, including a Common Foreign and Security Policy on intergovernmental terms.
Lever imperialismen ånyo? : Relationen mellan Kina och Afrika
Since Africa?s decolonization a number of foreign economic actors have begun toemerge in several African countries and they prove a vital role in many ways. China isone of the largest actor and they have a long history of political and economic ties withAfrica. China act primarily in Africa to meet their growing economy?s demand fornatural resources, and by providing aid and trade with development countries in Africathey get important natural resources like oil and iron ore in return.
Cooking banana farming system in rural Uganda : a comparison between agroforestry systems and non agroforestry systems
The demand for food, feed, fibre and fuel has increased in Uganda over the past 50 years due to population growth. Recurring extreme climate events such as drought and flooding, in combination with large-scale land degradation, have led to declining crop yields. Lack of equipment, money and socio-economic issues has contributed to low yields. However, the soils in Uganda have the potential to produce much higher yields than they do today.
This study, which was carried out in April-June 2013 in Kkingo District, south-east Uganda, examined the effects of agroforestry on yield of cooking bananas in small-holder farming systems. Six farms practising agroforestry and six farms with no agroforestry, which were chosen in cooperation with the NGO Vi Agroforestry, were compared.
