Marksättningar i Uppsala : En jämförelse mellan beräknat och verkligt utfall
Delar av marken i Uppsala består av mäktiga lerlager. Naturliga krypsättningar pågår ständigt i området, en process som i litteraturen benämns geologisk åldring. Ökad belastning i form av uppfyllnad kring byggnader och sänkt grundvattenyta till följd av pumpning av färskvatten bidrar också till sättningar. I ett nybyggt bostadsområde på Kapellgärdet har marksättningarna intill de pålade husen på vissa platser uppgått till 0.3 m på 10 år.Med geotekniska data för området har en jordprofil tolkats. Analys har gjorts utifrån den klassiska sättningsteorin för primärsättningar till av ökade effektivspänningar från fyllnadsmassor och grundvattensänkning.
Energianalys av hygieniseringssystem : jämförelse av befintlig pastörisering med integrerad termofil hygienisering på Kungsängens gårds biogasanläggning i Uppsala
The biogas plant Kungsängens gård, owned by Uppsala Vatten och Avfall AB, produces biogas and biomanure from organic household waste, food processing waste and
slaughterhouse waste. In year 2012, 4.4 million Nm3 of biogas were produced from 25 200 tons of waste. Before digestion all substrate is sanitized by one hour?s pasteurization at 70°C in order to kill pathogens. Another method, integrated thermophilic sanitation (ITS), is of
interest in order to decrease the energy demand.
Flygplansavisningens miljöpåverkan vid svenska flygplatser
The aim of this thesis was to answer a number of questions about the environmental consequences of aircraft de-icing. A further aim was to suggest how the environmental consequences due to the release of de-icing fluids can be measured and reduced.The main impact of the aircraft de-icing on the environment is due to the large oxygen demand for the degradation of glycol based de-icing fluids which are released in the environment. The effect of the increase in oxygen demand depends on where the degradation occurs in the ecosystem. In a sensitive ecosystem, the large demand of oxygen could provide an anaerobic environment which would be harmful for many types of organisms.In order to reduce the negative effects of the applied de-icing fluid, there is some type of collection system at every regular airport in Sweden. The methods of collection can be divided into two general groups, hydrological isolation or vacuum sweeper trucks.
Intuition i beslutsfattande : En studie om det intuitiva beslutsfattandet och dess påverkande faktorer vid Akademiska sjukhuset i Uppsala
Managers operating within the dynamic society of today are said to rely on intuition when effective and quick decisions are to be made. This skill or phenomenon has aroused an interest within the academic world of management whom has explored intuition, its relation to decision making and its influencing factors, especially in the private sector. Intuitive decision making is however not isolated solely to this sector but also involved in decision making associated to the public sector. Therefore, the aim of the thesis is to investigate whether managers at the hospital Akademiska in Uppsala involve intuition in decision making and to what extent the factors time, amount of information, individual experience and decision complexity influence the intuition.The theoretical framework includes academic research regarding how intuition and rationality affect decisions, the concept of intuition and factors influencing the intuitiveness of decision making. Furthermore the theoretical discussion explores intuition connected to leadership, negative aspects of intuitive decisions and a comparison between different factors that separates public and private sector in terms of decision making.

Snusets påverkan på balans : skillnad i posturalt svaj hos dagligsnusare före och efter uppehåll från snusbruk
SyfteSnusandet har ökat de senaste åren, särskilt bland kvinnor och yngre personer och till flera samhällsgrupper. Rökning har under många år genomgått rigorös forskning och därigenom bevisats vara förenat med ohälsa. Däremot är forskning på snusanvändandets hälsoeffekter eftersatt. En fysiologisk effekt som föreslagits av långvarigt snusande är påverkan på balans (posturalt svaj). Uppsatsens huvudsyfte är att undersöka effekten på balans av ett långvarigt (sex veckor) uppehåll från snus i en grupp av dagligsnusare. MetodI studien genomförde dagligbrukare av snus (n=13) tester av posturalt svaj före och efter sex veckors uppehåll från snus.
Riskmodell för kabelsträckningar i mellanspänningsnätet i Sverige
The society of today is largely dependent on electricity and the dependence does not show any signs of declining. Reliability of supply will become increasingly important in the future and it is therefore important to investigate factors affecting the failure rates in electrical components.Sweden was hit by several severe storms during the 00?s. As a result of this many overhead lines in forests were cablified. In urban areas underground cable systems have been the norm for many years.
Ultraljudssvetsning: ett komplement eller ersättning till symaskinen?
AbstractThis bachelor thesis has been assigned by the company ACG Nyström, Borås. ACG Nyström is working in cooperation with a Swiss company named Jentschmann AG. Jentschmann is a manufacturer of ultra sonic welding machines which ACG Nyström is marketing in Scandinavia and the Baltic States. On behalf of Jentschmann AG the company has the aim to introduce the ultra sonic welding technique to new companies.The aim of this thesis is to compare traditional sewing machines with ultra sonic welding machines within two textile areas, protective clothing and outdoor living.Two investigative questions have been formulated for this purpose: what are the differences between a sewing machine and an ultra sonic welding machine? Is it possible to replace the sewing technology with ultra sonic welding? These stand as guidance for this paper.To gather knowledge interviews, literature studies, and tests on two different ultra sonic welding machines were performed.
Öl- & alkoläsksmarknadsföring ur genusperspektiv
Alkoholkonsumtionen i Sverige är högre än på mycket länge. Med nya överenskommelser,som öppnade möjligheter för alkoholbranschen att marknadsföra sina produkter, utsättskonsumenter för ökad påtryckning av önskad kommunikation från företagen. Företagenskommunikation riktar sig gärna till den yngre allmänheten som ofta formar sinauppfattningar och attityder genom inlärning och erfarenheter. Uppsatsen behandlarhuvudsakligen företagets kommunikation med hjälp av tre angreppssätt; medieval,förpackning och reklam. Beroende på förespråkarens kön uppfattas reklamens inriktning oftaolika.
Interna processer : Modell för ett effektivt returstålsflöde
The last decade has created an increasing pressure on companies to decrease their impact on the environment and to increase their effectiveness of recycling the company?s resources, especially for the steel industry. Companies have also started to realize the economic aspects of an effective internal reverse logistics. In the past the value of an effective internal reverse logistic was something that companies tend to underestimate and there are few academic studies done in this area. The purpose of this essay has been to identify key factors to create an effective in plant storage, transport, sorting and handling of returned steel. From these factors a generalized model for creating an effective return steel flow will be developed.
Dolda vinstmöjligheter : En studie om överavkastning vid ändring av indexkompositioner
Syfte: Undersökningens syftet är att mäta huruvida det går att få ut en överavkastning av aktier som väljs in i (respektive ut ur) OMX Stockholm Benchmark (OMXSB), som följd av att ett index ändrar sin komposition. Delsyftet är att undersöka om det går att se en signifikant ökning av handelsvolymen i anslutning till ändringsdagen.Metod: Studien tillämpar en eventstudie som undersökningsmetod av kvantitativ karaktär. Studien undersöker indexet OMXSB och innefattade totalt 111 stycken ingående och utgående aktier fördelat på 10 tillfällen. Två eventfönster har konstruerats; ett kring annonseringsdagen och ett kring ändringsdagen. Den procentuella handelsvolymen har mätts över eventfönstret kring ändringsdagen.Resultat: Den genomsnittliga kumulerade överavkastningen för eventfönstret vid annonseringsdagen uppgick till 1,02 % (-6 %) för de aktier som valdes in (ut).

Isolating microorganisms from marine and marine-associated samples : a targeted search for novel natural antibiotics
The search for antibiotic compounds from the natural environment has been going on for seven decades, ever since penicillin entered the market and antibiotic treatments became routine. The evolutionary pressure put on the pathogenic microorganisms induced a rapid spreading of naturally occurring resistance genes, leaving only the option of finding new antibiotics to treat the resistant pathogens. Microorganisms have been extensively mined for their biosynthetic abilities to produce biologically active compounds. To date, more than 23 000 microbial natural products have been discovered. The Actinomycetales are ubiquitous bacteria that have been used for antibiotic discovery for more than half a century, and over 10 000 natural products have been identified from the order.
Giraffens blodtrycksreglering
Through previous studies during my education, I have experienced that chemical deicing road salt is a known problem, mainly in southern Sweden. Road salt causes damage to the environment and also damage to vehicles and structures such as bridges, etc. Road salt causes vehicles and steel constructions to rust, leading to increased costs for repairs of damage to structures. Road salt also causes damage to the plants and the economy to suffer, when plant material and soil needs to be replaced. In order to get closer to a solution, I put up three questions.
