Läslust en brinnande känsla i magen. En studie av 9 - 12-åringars upplevelser och uppfattningar av läslust.

The aim of this Masters thesis is to investigate the factors that contribute to childrens feelings of enjoyment and wellbeing while reading pleasure reading. The research is founded on qualitative interviews with eight children aged between 9 and 12 years. In the review of the literature different theories of reading experiences are examined and the theory of flow is used to analyse and interpret childrens statements of reading experiences. The theory of flow has not been developed to investigate reading but aims to describe and explain when and how people experience happiness and joy. The results of this study reveal that many different factors influence childrens reading.

Design and evaluation of an AGV-system for Tetra Pack in Lund using simulation

This examination work is the final work in our education to become a Bachelor of Science inMechanical Engineering by the University of Lund.The main purpose with this work has been to develop a new effective material handling system for TPPM AB in Lund since the existing system starts to become out of date. The future system that is going to be installed shall have the capacity to support all machines with unit-, semi- and finished goods during full production. The work has also included studying the possibilities to change the material flow in a positive way between the storage and the production when one is using existing buildings.During our work we have been used a simulation program called AutoMod, performing company visits, interviews and reviewed internal and external information to create a picture of what the best conclusion can be. During the work we have contacted five suppliers to receive system solutions and quotatioris. The suppliers, which have been contacted, are Swisslog, Moving, Rocia, Christensen & Hansen and ABB.

Unified Flow Sensor

Value stream mapping is a tool that is frequently used by many different companies. It is a great tool used to achieve the work that follows the theories of lean production. The tool is used, however, only frequent on the factory floor and the method is also designed based on this type of use.An interest of applying the method on administrative parts of the company has occurred lately. Administrative parts of the company refers to the part that does all the planning such as purchasing, receiving orders, customer contact, contact with factory floor and other work that is made around the actual manufacturing. But the knowledge about applying value stream mapping on the planning part of the company is lacking because the method is relatively new.In this work, a comparison is made between the introduction of value stream analysis on production and planning.

Lean inom offentliga myndigheter.

Systemutveckling har länge kantats av problem och oförmåga att möta nya problem och krav som uppstår under processen från ide till färdig produkt. För att möta de problem som de traditionella systemutvecklingsprojekten innebar så arbetade Ken Beck et. Al. (2001) fram det agila manifestet, det agila manifestet beskriver de kärnvärden som systemutvecklingsprojekt bör arbeta utefter, detta för att öka flexibiliteten och minska problemen med långa ledtider.SCRUM är en agil systemutvecklingsmetod som togs fram av Jeff Sutherland och Ken Schwaber, detta efter att de båda hade sett behovet utav en metod som klarade att möta snabba förändringar och att kunna möta problem under processens gång.För att undersöka hur hantering av problem i agila systemutvecklingsprojekt fungerar i praktiken har en fallstudie genomförts på ATS väst hos CGI.En stor del av problematiken i systemutveckling är distansen mellan de inblandade parterna, något som påverkar arbetsmetodiken. Detta resulterar i en mer omfattande dokumentation än vad den agila arbetsformen förespråkar och minskar även den personliga kommunikationen.

Elevers uppfattningar om laborativt material i matematikundervisningen

Syftet med denna studie var att ta reda på elevers uppfattningar om laborativt material i matematikundervisningen. Även hur liknande form av undersökning kunde gynna läraren till att få reda på vilken typ av undervisning som eleverna föredrar. Motivationen som låg till grund för studien var erfarenheter utifrån VFU (verksamhetsförlagd utbildning) samt erfarenheter av forskningslitteratur. En stor del av forskningen har påvisat att elever som arbetar med laborativt material i matematik presterar bättre än elever som inte arbetar med laborativt material. Därför förespråkar forskningslitteraturen inom detta område att lärare borde arbeta med laborativt material under alla åren i skolan.

Behovet av kommunikation om kommunikation - En fallstudie om intern kommunikation på ett folkbibliotek

The aim of this study is to gain knowledge about the internalcommunication at a public library in Sweden, focusing on the flow of information and the library employee?s role as a source and receiver. This is an important subject because internal communication affects not only the internal work, but also the users. Despite this there are few studies about internal communication in libraries. The research questions used are: How do the employees perceive the role as source of information, and what choices do they make before they spread information? How do the employees perceive the role as receiver of information? How do the employees feel that the information flow works in the organization as a whole?The research is founded on five qualitative semi-structured interviews with the library employees.

CCTV och Al Jazeera : Likheter och skillnader i de internationella nyhetsprogrammen

Stockholms Universitet, Instutitionen för journalistik, medier och kommunikationJMK, Karlavägen 104Box 27 861, 115 93 STOCKHOLMTel: 08-16 20 00Titel: CCTV och Al Jazeera ? likheter och skillnader i de internationella nyhetsprogrammen Title: CCTV and Al Jazeera ?similarities and differences in the international news programsFörfattare: Hanna Strid, hanna.strid@gmail.com, Marta Kaszuba, marta.kaszuba@hotmail.com.Handledare: Christian ChristensenC-uppsatsHöstterminen 2013This essay aims to identify what similarities and differences there are between news broadcastings from Chinese CCTV and Al Jazeera English which has its national headquarters in Qatar. When national channels broadcasts internationally, it is interesting to see what they choose to convey as that day's news flow and how to represent their country. It can depend on many different things such as structures of media ownership in the country and cultural context. The research methods used have been empirical studies and comparative analysis of a total of ten broadcasts of the largest daily newscasts on both channels, both news programmes are called the News Hour.

High Orbit Ion Cannon : Går det att skydda sig?

The development of productivity in the construction industry has long been at a steady state compared to the manufacturing industry. Studies have shown that, amongst other things, waste on construction sites can reach up to one third of the total production cost. This has been observed from different aspects, and change is forthcoming.This thesis aims to provide a foundation for an increased productivity at production sites of building bridges. It is primarily based on a field study at Skanska, at a bridge construction site near Grängesberg. Via continuous interviews with the whole production crew, construction workers and management, information on interference and possibilities of improvement at the work site has been documented.

Slöserijakt i betongdjungeln : En tidseffektivisering av monteringsprocessen inom stål- och betongprefab

The different aspects of each individual construction project such as the general conditions, design and economic restrictions as well as many more factors mean it is difficult to standardize building processes or plan in detail based on past experiences. As a result operational efficiency is often reduced, and unnecessary waste is generated. To make an organization more efficient and therefore reduce waste production everybody involved needs to appreciate and understand the improvements that can increase the organization?s efficiency. To investigate these improvements a time study was performed on two different construction sites, both of which involved buildings being constructed of prefabricated steel and concrete elements.

Utgångspunkten i vår fallstudie har varit att studera effekter av utvecklingsprogrammet ?Bra mottagning? som utfördes på Centralsjukhuset i Kristianstad (CSK), Barn- och ungdomsmottagning mellan åren 2006- 2008 utifrån ett medarbetarperspektiv.

Direct-EGR tillämpat på HCCI

The Homogeneous Charge Compression Ignition (HCCI) engine is promising in terms of lowNOx, low particulates and high efficiency. Due to its homogeneous charge, where thecombustion starts almost simultaneously from a number of points in the combustion chamber,only lean mixtures are possible to burn because of the resulting rapid combustion, which is muchfaster than the combustion in an SI-engine or a diesel engine. When richer mixtures are used thecombustion will start earlier and also be more violent.To phase the combustion later and lower the combustion speed, external cooled EGR can beused. The EGR-system used in this thesis uses a divided exhaust channel where one channel andits corresponding valve are used only for transporting EGR back to the intake system.Consequently the EGR-valve is connected to the intake pressure. This system is called Direct-EGR (D-EGR).Engine tests verified that the CA50 indeed is phased later when cooled EGR is used.

Värmeåtervinning på förskolan Rymdattacken 1 : En jämförelse av värmeväxlare

In the spring of 2014 Sweco Systems AB were commissioned to design a ventilation system for a newly built preschool in Linköping. Terms from the client was that it cost efficiency would cope with the energy demands that are placed on the building. The unit chosen was a cross-flow heat exchanger, and this work is to compare it with two other heat exchangers to see if a more energy and cost efficient could have been chosen. The heat exchangers that was chosen for the comparison was a rotating- and a counterflow heat exchanger. Simulations have been made to the different heat exchangers by the manufacturers.

Temperaturstyrning av aluminiumextruderingsprocess

In this final thesis a rough description of aluminium extrusion is made, the importance of temperature of both the raw material and the extruded profile for a good profile quality. The difficulty in controlling these temperatures are discussed and attempts to increase the control are described. The attempts are basically made by controlling the furnace that is heating the raw material. This is done in a manner that the raw material reaches its final temperature shortly before it is extruded. An IR-camera at the press can be used for profile temperature measurements.

Näringsretention i återskapad våtmark på betesmark : studier av en mad vid Bornsjön

It is important to construct or recreate different types of wetlands and study their retention of nutrients, since knowledge of their effectiveness in this matter is poor. In 2003 a wetland was constructed on an old meadow on the western shore of Lake Bornsjön in central Sweden. The main purpose of the wetland was to reduce the amount of phosphorus entering the lake, which is the back-up water supply for Stockholm when the city cannot obtain water from Lake Mälaren. Large areas around Lake Bornsjön consist of agricultural land and the nutrient concentrations in the inflows to the lake are usually relatively high (approx. 1 mg/l total nitrogen and 0.05-0.1 mg/l total phosphorus).
