Lexikal organistaion hos flerspråkiga barn - enligt den förkortade Kent-Rosanofflistan på svenska och arabiska

The aim of this study was to examine bilingual childrenslexical organization and to investigate weather bilingual children hadundergone the syntagmatic-paradigmatic shift in grade four. Thirtychildren from multi-ethnic areas were tested with Kent-Rosanoff wordassociation test in both Swedish and Arabic. The results showed thatmore than 40% of the children had undergone the shift in bothlanguages, 20 % had undergone the shift in only one of theirlanguages and almost 40% had not made the shift in any language. Acomparison with results from monolingual Swedish children in gradethree in a previous thesis, showed that the bilingual children in thisstudy did not reach the corresponding level of lexical organization.The study points to the necessity of including tests regarding lexicalorganization when assessing both mono- and bilingual children withsuspected language impairment. The study also underscores theimportance of supporting mother tongue development in bilingualchildren by for instance adequate mother tongue education.

Men först, låt mig ta en "röstie"

Today, we see tendencies of politicians being more active in social media using selfies. According to previous research using selfies is associated with being self-centered and narcissistic. It is not known though what implications the behavior will have for a selfie-using politician in terms of chances of being elected. This study aims to contribute to the research on political communication and social media behavior. More specifically the study intends to investigate whether there is a difference between voters' views if a politician uses selfies or not, and whether there is a difference by gender.

Flödessimulering av förrådsupplägg: En jämförande studie av olika materialplocksmetoder vid varierad produktmix och produktionstakt

En hårdnande konkurrens inom försvarsindustrin medför att BAE Systems Hägglunds AB står under ett effektiviseringsprojekt, Vehicles Production System. Projektet innebär att verksamheten ska samlas för att skapa ett störningsfritt flöde och syftet med projektet är; ? minskade ytor, ? ökad produktion med mindre resurser, ? ökad flexibilitet vid varierad orderingång, ? minskade ledtider, ? ökad lönsamheten för att kunna satsa mer på egenutveckling. För att uppnå detta ska verksamhet samlas vilket bland annat innebär att tre tidigare förråd för eftermarknad och produktion skall slås samman och nya produktions-linjer skall tas i bruk. Syftet med examensarbetet är att analysera tänkt upplägg för detta nya förråd samt rekommendera materialförsörjningsmetod till slutmontage bandvagn vid varie-rad produktmix och produktionstakt.

Reduktion av föroreningar i processvatten från en äggfabrik i Brasilien : Kväve- och fosforrening i anlagda våtmarker.

A water treatment unit consisting of two aeration basins, two settling tanks, a residence basinand a horizontal subsurface flow wetland were used to treat wastewater from an eggprocessing factory in Brazil. The aim of this paper was to determine the efficiency of thesystem in reducing nitrogen, phosphorus, BOD5 and TSS (among other parameters) andgetting a further understanding on different kinds of constructed treatment wetlands as well astheir nitrogen and phosphorus removal processes. The wastewater from the factory consistedof process water from manufacturing and water used for cleaning, no stormwater or sewagewater entered the system. Tests were taken three times a month from October 2013 ?til April2014.

Hur påverkar gummigolv i grisningsboxen suggans liggtider, liggbeteende och hennes tid för att lägga sig?

In the farrowing pens the amount of bedding material and the quality of the concrete floor has a huge impact on both the sow and the piglets. In this study imbedding of rubber flooring on the solid area in the farrowing pen was used to see if it had any effects on the sows lying behaviour when compared to concrete. Another important aspect was to evaluate if the rubber floorings had a high enough durability to resist the normal wear in a farrowing pen. Concrete flooring is assumed to have a higher thermally conductive effect then rubber which can affect the sow?s chance to cool down.

Flervariabel reglering av industrirobot

The goal of this Master thesis has on the one hand been to create a simulation environment for robots, where not only the simulations in this work can be performed, but also similar robot simulations, and on the other hand to study regulators that can increase the possibilities of rejecting disturbances on an industrial robot. The robot model used has three degrees of freedom, corresponding to the three main links on ABB:s IRB7600. The simulation environment is created using Matlab, Simulink, and Robotics Toolbox. It is constructed in a general way and can be used for simulations of other robot objects created in Robotics Toolbox. A gain scheduling is added to the LQ-regulator, where the feedback matrix is varied depending on the arm position in the workspace.

Pragmatisk mjukvarutestning : Hur kan agila metoder implementeras i ett pågående utvecklingsprojekt?

There are several ways of conducting software testing where some may include users and others may include personnel whose work task is to execute test on systems. Although most developers and project managers understand the point of testing the system, it is not always being done and the most common reason is that there is no time for it. However, this is a false assumption as it may instead cause some bugs in the system that would not have been there in the first place if tests had been there to prevent bugs in the code.My purpose for this thesis was to find suggestions for changes in the development process in an ongoing project used by Acino and Svenska Försäkringsfabriken in order to increase the quality of the system used. In this thesis, I have approached the purpose by pursuing a case study of the two companies through observation and interviews. By doing this I acquired the relevant information to make suggestions for change.

Kalciums och magnesiums inverkan på arsenikavdrivningen i virvelbäddsugnen : The influence of calcium and magnesium on the expellation of arsenic in the fluidized bed furnace

In the fluidized bed furnace at Rönnskärsverken, Skelleftehamn, sulphur-containing ore concentrates are roasted in order to remove about 50% of the sulphur in the incoming ore concentrate. This occurs in order to reach the goal of a matte containing 55% of copper in the following smelting process. At the same time as the ore concentrate is partially roasted pollutions as arsenic, antimony and bismuth are expelled. Earlier made thermodynamic calculations of equilibrium suggested that calcium and magnesium form stable compounds with arsenic and thereby inhibit expellation of arsenic in the fluidized bed furnace, an element that is undesired. The purpose of this thesis work was to gain knowledge of the mechanisms behind the formation of these stable arsenic compounds.

Hållbar design för en bättre värld - med hemlösa i fokus

The aim of this project is to examine the needs and problems that exists amongst homeless people and to develop a solution that will help them in their everyday life. Since the homeless are a relatively large vulnerable group i Sweden, their everyday lives could be made easier in many ways.A clear definition of the target group is put together to create a good starting point. What state and help orginazations do to help the homelss and the society?s view of the homeless is also relevant and has been documented. Four personal stories have been put together to desicribe cases of clear problems existing in everyday life.Several interesting problems has been defined from the research and acceptance in the communtiy, desire to be seen and heard and a lack of confidence were the main needs.

Sju heuristiker för utvärdering av webb-API:er

The amount of web APIs that are open to the public is increasing fast. Both the free web APIs as well as the ones that cost money to access. Both bigger and smaller organizations, professional and non-professional developers use these web APIs to add value to their systems or use it to create new applications. This is an area study where alot of research has been done in the last few years. In spite of this there are still no user-centered evaluation methods for web APIs.

En utvärdering av Peabs inköps- och avropssystem

 This report is an evaluation of Peab's purchase and call-off system, PIA.PIA is used to order goods for Peab's construction sites. The background to the work is that users of the system have understood the system cumbersome to use when purchasing goods for construction sites. The evaluation was carried out by the interviews and tests with users of the program, in this case, supervisors and site managers at the company. Ten users of the system were interviewed and eleven people have carried out a test order.The focus is primarily on the test order that users have implemented, which has been clocked and analyzed for time and cost. The evaluation is also a user analysis concerning how the users perceive the program, mainly in terms of usability, functionality and benefits.The result of this report shows that PIA is economically profitable to use for the purchase of goods for construction sites.

Nätdroger - Utmaningar för myndigheter, enskilt och inom ramen för samverkan

The aim of this study was to examine how the new established phenomenon of ?Internet drugs? causes challenges to organizations, both individually and in relation to collaboration. The study is based on qualitative semi-structured interviews with representatives from three organizations - one youth police unit, one medical addiction centre and four units working within social services. The theoretical approach that was used is theory about human service organizations, theory about collaboration and new institutional organizational theory. A conclusion is that the current drug classification is problematic and mainly challenging for the organizations that focus on prevention work and early interventions.

Finns det daglig variation i resistans i de nedre luftvägarna hos häst?

Among researchers it has been established since decades that humans and animals have an internal biological clock that controls certain physiological mechanisms. One example regarding humans is the impairment of lung function during the night, causing the phenomenon ?nocturnal asthma? among asthmatics. Only a few studies concerning respiratory circadian rhythm in horses have been done previously and they showed a daily variation in horses with a chronic or an acute respiratory disease. The technique used in those studies was the conventional technique, which is invasive and less sensitive than the technique used in this study.
