Produktion av Pyrolysolja från kvistrejekt
Fast pyrolysis is a method for converting biomass into three energy rich products: char, gas and bio-oil, where the latter is most interesting. Pyrolysis is an endothermic process where biomass is heated in an anaerobic environment and, with the right operating conditions, up to 80 %wt bio-oil can be extracted. Key parameters for fast pyrolysis are: stable reactor temperature (~500°C), short residue time for gas in the reactor (<2 s) and a very high heating rate for the biomass. Today there are several different process solutions for fast pyrolysis, where fluidized beds and rotating cones are most developed. Bio-oil has compared to fossil oil: lower heating value, low pH and also polymerizes with time. Because of this upgrading is desirable for increasing competitiveness.
Ställtidsreducering med hjälp av SMED i pressgjuterianläggningar
To maintain production in high salaries countries and strength in competition against other companies, it is today more important than ever to maximize production, offer a wide spectra of products and be able to deliver on the customers desire of shorter and shorter delivery time. Flexible production and short time spent on die changes is vital to achieve these desires. The interest for die changeover time reduction grew in the same pace as the demand for increased product variety grew. SMED as a method of reducing time spent on die changeovers were developed in between 1950-1970, by the Japanese Shigeo Shingo.The purpose of this thesis work has been to investigate the result of SMED in a die casting facility, and compare the result from it with the result considering time spent on die changeovers when investing in new equipment. The goal is to implement a thorough investigation by using the SMED method at Tenhults Pressgjuteri AB and make a brochure that have to be simple to understand, in purpose to draw interest to the advantages of using SMED as a method.Commissioned by the Swedish foundry association Swecast, the work has been carried out by studying die changeovers at Tenhults Pressgjuteri AB, where filming and interviews with the operators have been included in the analysis.
Visuell kommunikation i offentliga verksamheter
The aim of this paper is to investigate the subject matter of visual communication in presentation brochures of two Swedish regions: Region Halland and Region Dalarna. My focuses are the following questions: what is the aim of the brochures and in what ways does the visual material relate to that aim? How can strategic communication be defined through a visual perspective and in what ways is it useful in the context of presentation brochures of the regions? What sort of communicational functions are specific for the visual material in relation to the written language of the brochures? Lead by these questions, I start by analyzing the brochures through a textual analysis and a social semiotic approach. The result shows that the aim seems to be both political and commercial, but that the visual elements relate more strongly to the commercial aim than to the political aim by the way they strive to present a positive image of the region. The visual elements work in strategic ways that I define as visual strategies.
Hydroperikard hos katt : patofysiologi, diagnos och behandling
Hydropericardium or pericardial effusion (PE) is the accumulation of fluid in the pericardial sac and is often secondary to pericardial diseases or diseases related to the heart. It is unusual with clinically relevant pericardial diseases in cats but pericardial effusion is the most common one.
Since PE causes serious symptoms and may lead to death it is important with a quick diagnosis and treatment. PE can be acute and cause cardiac tamponade, which gives severe clinical signs. Cardiac tamponade needs to be treated immediately or else the cat will die from cardiogenic chock. More common is chronic PE where the fluid accumulates during a longer period of time and the pericardial sac stretches.

Algebra och ekvationer ? att underlätta lärande : Lärandet börjar byggas vid första kunskapsmötet
Abstract This study aims with a pragmatic approach to investigate the learning about how to solve simple equations, and what the teacher can do to help the student. Four questions asked are: (i) How and why will learning take place? (ii) What will complicate learning? (iii) How to support and facilitate learning? (iv) Is it possible to identify an influence between identity and learning? To answer these questions a qualitative study in elementary school is done. The results of the investigation are compared with previous research, and an interview with the teacher is presented. The recorded lessons are analyzed with PEA (practical epistemology analysis), and letters from the students with the Ecological Systems Theory of Bronfenbrenner.

Analys av en metod för att extrahera generella regler från multipla nät
Rapporten som följer är en analys av en metod som genererar regler från neurala nätverk. Metoden heter VI-Analysis (Validity Interval Analysis) och är framtagen av Sebastian B. Thrun [Thrun]. VI-Analysis arbetar på det sättet att det neurala nätverket ses som en svart låda där endast de inputvärden och outputvärden som finns i nätverket används som underlag när regler ska genereras. Dessa inputvärden och outputvärden kommer sedan att få tillåtna intervall av VI-Analysis.
Komplexiteten i ett event : Kommunikationskanalen som leder till relationer
Events are a growing channel for companies and organizations to reach out to their customers. The com-munication channel opens up to satisfy all human senses. Which are required for a message to go into the receiver and be memorized. The research gap we decided to contribute to we made a case study of an event that is not sport related and looking at both the transmitter perspective and receiver perspective. Thus, the purpose of our study is to increase the understanding of how the transmitter should be able to convey the purpose and goal of the event to the receiver.
