More than fifty percent of the world population today lives in cities, and the pressures of urbanisation are particularly present in developing countries. As landscape architects, it is important to gain knowledge about the effect of urbanisation and ways to prevent the negativities. Experiencing the effects in person in a developing country, as well as learning from and about other cultures, enhances the understanding for global situations. Dar es Salaam is located in one of the most rapidly urbanising regions in the world, which puts pressure on the environment and the humans living in it. Lack of means to regulate land development has led to a situation where expansion of unplanned settlements occurs, with spatial disorder as a consequence. This has in the extension led to a decreasing amount of publicly available and qualitative green spaces, and degradation of the few ones that exist. There are facts that strengthen the status of urban parks, which especially becomes relevant in developing countries where many people live in sparse and exposed conditions.

This work consists of a survey and risk classification of eleven metal industries including foundries, finishers and engineering industries in two industrial areas in Mora. The study follows a method called MIFO (Method of Surveying Contaminated Sites) composed by the Swedish Environmental Protection Agency. In the method assessments of the degree of hazard posed by the pollutants, the level of pollution, the conditions of dispersal, sensitivity and the degree to which the area is worthy to protect are made for each contaminated site (object). The assessment classify the objects into four risk classes in which risk class 1 denotes a very large risk, 2 large risk, 3 moderate risk and risk class 4 little risk. The work of surveying using MIFO is divided into two phases.

In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.

One of today problem at IVT industries would be assembly of insulation on water cisterns. The element of assembly insulation on the cistern gets too elevated; hence one has to climb onto the stand the cistern is assembly on. This will increase the risk of work related injuries when there is a risk of falling down. It?s also rather strenuous on shoulders due to work with your arms high above your head.

Abstract:Ambulance nurses have in their everyday work a varied work environment, the pace of work can quickly shift from being calm and structured to be a severe acute situation.Objective: The aim of the study was to describe how professional nurses in the ambulance operations experience their physical and mental work environment in daily practice.Method: A qualitative interview study with semi structured questions was used. The study group consisted of two women and three men, ages between 27?42 years. The study was carried out on an ambulance station in central Sweden. Based on collected data, a qualitativecontent analysis was performed that resulted in three categories.Results: The result showed that the ambulance nurses regarded that it was a lot of heavy lifting.

This master thesis was made to validate hydropower models of a turbine governor,Kaplan turbine and a Francis turbine in the power system simulator ARISTO atSvenska Kraftnät. The validation was made in three steps. The first step was to makesure the models was implement correctly in the simulator. The second was tocompare the simulation results from the Kaplan turbine model to data from a realhydropower plant. The comparison was made to see how the models could generatesimulation result that was similar to the reference power station.

The purpose of this study is to see how five different local radio stations, P4, within the public service organization Sveriges Radio communicate with their listeners through Facebook and how they differ from each other.We have also studied how the radio stations follow Sveriges Radios? policies for socialmedia usage and how the communication through Facebook can benefit thetraditional radio. Our study contains a combination of quantitative content analysis with qualitative interviews. We studied the five stations? Facebook pages from for the quantitative content analysis and interviewed those who were responsible for the social media pages, such as web editors and channel managers.Our conclusions are that the P4-stations communicate through Facebook to create a dialogue with the listeners and to reach two-way communication; the stations published mostly written updates that encouraged interactivity.

Syfte och frågeställningStudiens syfte är att, utifrån NyTidstestet, undersöka elevers grovmotoriska grundfärdigheter i årskurs 6 i Stockholmsområdet.Utifrån detta syfte har vi valt att använda oss av följande frågeställning:- Hur ser de grovmotoriska färdigheterna ut för elever i årskurs 6, när de bedöms enligt NyTidstestet?- Vilka skillnader framkommer, hos eleverna, mellan de undersökta stationerna?MetodFrågeställningen har besvarats genom en observationsstudie på sjätteklassare i Stockholmsområdet, sammanlagt 113 elever. Varje elev har observerats utifrån NyTidstestets observationsschema, där eleverna vid sju stationer bedömts enligt fyra kriterier: "mycket tillfredställande", "tillfredställande", "små brister" och "stora brister". Varje station innehåller en eller två grovmotoriska grundformer.ResultatDe undersökta elevernas grovmotoriska färdigheter är bristande. Hela 48 procent av övningarna kunde inte utföras på ett tillfredställande eller mycket tillfredställande sätt.SlutsatsUndersökningen visar att eleverna får en allt sämre grovmotorik och i och med den nya läroplanen (Lgr 11) tror vi inte att elevernas grovmotoriska färdigheter kommer att bli bättre.

Ekologiska livsmedel a?r idag ett allt mer debatterat a?mne da?r majoriteten av den svenska befolkningen a?r positivt insta?llda till ekologiska livsmedel. Trots konsumenternas positiva insta?llning och den o?kade marknadskommunikationen som de stora livsmedelsbutikerna bedriver idag a?r fo?rsa?ljningen av ekologiska livsmedel i Sverige fortfarande la?g, endast 5,6 % av den totala livsmedelsfo?rsa?ljningen. Fo?r att o?ka den ekologiska fo?rsa?ljningen a?r det av stor vikt att bemo?ta konsumenten med en anpassad marknadskommunikation.

AbstractDegree thesis Solid content in Lime Mud By Andre Flodin Process operator program ? Umeå University 17/6 ? 2014 Pages: 21A thesis was made on Billerudkorsnäs production unit in Karlsborg where lime kiln in the causticising department of chemical recovery plant does not meet the required production. Causticising department is the final step in the chemical recycling unit. There, the filtered green liquor is mixed with lime to recover the cooking chemicals used in the pulp factory. The cooking liquid is called white liquor.

Bakgrund Dagens samhälle ställer allt större krav på den enskilde individen att bidra till ett hållbart samhälle, där återvinning av förbrukade material är en del. Samtidigt talas om tillgänglighet för alla individer i samhället och lika rättigheter.Syfte Studien syftar till att undersöka hur förutsättningarna i miljön ser ut vid återvinnings-/miljöstationer för rullstolsburna i Örebro Kommun.Undersökningsmetod En observationsstudie av miljöfaktorer har gjorts utifrån egen utarbetad checklista med grund i bland annat bedömningsinstrumentet Housing Enabler samt rekommenderade mått från svensk lagstiftning angående byggnormer för tillgänglighet. Urvalet skedde genom bekvämlighetsurval.Resultat Observationerna av återvinnings-/miljöstationerna indelades i åtta kategorier, utifrån typ av station. De hinder som observerades var för höga/låga kärl, otillräckligt manöverutrymme, hindrande trösklar/trottoarkanter, tunga dörrar utan automatik och tunga lock/luckor på återvinningskärlen.Slutsats Samtliga observerade återvinnings-/miljöstationer innefattade miljöhinder för rullstolsburna vilket påverkar möjligheten till självständig återvinning. .

Nowadays Wireless LAN is playing a more and more important role in network systems. After 1999, in which the IEEE organization published its Wireless Local Network standard 802.11[1], many people saw the advantages of the standard but also the lack of support for multimedia streaming. A lot of research work has been done on the proposed IEEE 802.11e standard draft during the past 4 years. It is supposed to be able to fully support Quality of Service. The final version will be published early in 2004.

This report describes the development and implementation of a system for transmitting digital information at high speeds from a miniaturized submersible developed by the Ångström Space Technology Centre at Uppsala University. For instance, the vehicle shall transmit image data ? even stream live video - through an optical fibre to a monitor in a ground station. Hence, the system shall be used both to convert the image data to make it transmittable, and to recreate it at the receiver.The work includes a pre-study of the programming language and the technology used. A concept for the solution is presented together with main components later broken down into internal functions.

The purpose of our study is to see how the interaction between the social services and police work when a child under 15 years is suspected of crimes.What happens to the child from an agency perspective? How is the experience for the child and how do they get their voices heard? How is the professional perspective for a child when a child is suspected of a crime? What do the various authorities for short-term and long-term measures for the child?We have chosen to do a qualitative study using semi-structured interviews. The study includes six interviews with two police officers, three field secretaries and a social worker in two different municipalities. A medium sized municipality, and a larger community.The people we interviewed think differently about collaboration. The municipality have different workforms.
