Biochar as soil amendment in flow-through planters - for increased treatment of zinc roof runoff

In times of increased flooding, enhanced by climate change, polluted stormwater poses an increased threat to the environment through contaminated water entering waterways. Bioretention utilizes natural processes in soil and vegetation to treat pollutants and combat this threat. Biochar produced through pyrolysis, has a high cation exchange capacity (CEC) and could therefore increase treatment in bioretention systems. This research applies a literature review, interview, and a model to explore the benefits and disadvantages of biochar in order to specify a soil-mix through an understanding of the production process and preferred application rate. High purification through CEC, increased water holding capacity, and carbon sequestration being the benefits discussed.

Biomekanisk mätmetod och ergonomisk analys av träningsmaskiner

To get the maximal output of your exercise in gym machines, there are different factorsto be considered. For example the strength of the muscle varies dependent on the positionof the muscles. To get the best results of the exercise the load has to reduce and increaseat specific positions.This study was made in cooperation with Caretaker Scandinavia AB, a company forsales, marketing and development in health care. They are general agent for Nordic Gymwho works with manufacturing of equipment and machines for gym and fitness.The aim of this study was to generate a method of measurement to evaluate and controlthe biomechanics of Nordic Gym´s workout equipment. A protocol for an ergonomicanalysis on the equipment has also been elaborated.One of the methods to measure the biomechanics was to measure the torque through thewhole movement.

?Vi är allt från detektiver till terapeuter? : En kvalitativ studie om hur socialsekreterare inom ekonomiskt bistånd upplever sin arbetssituation

AbstractOur purpose was to understand how social workers experience the possible complexities that working with economical aid can entail. As an example we chose to focus on long-term economical aid work. We aimed to address the question of which factors could affect their work. In a prior study, done by Dellgran & Höjer (2003) the conclusion was drawn  that  the combination of economical aid, healthcare and schools makeup a third of  practical social work in the terms of the proportion of the amount of social workers, but only 8 percent of the research is done in those areas. Other studies (Stranz, 2007) demonstrate that the research that is done on working with economical aid is deficient.

Analys och utveckling av boggi till ramstyrd dumper

Volvo Construction Equipment is one of the worlds largest manufacturer of heavymachinery. In Braås, Sweden, they develop and manufacture articulated haulers inseveral sizes. The biggest, the A40, is capable of loading almost 40 metric tonnes.These haulers have a bogie to distribute the forces of the load evenly onto the two axlesand there wheels. The bogie is constructed using a rigid balance beam on each side ofthe frame connecting the axles or an independent solution using hydropneumatics.An analysis has been made in order to establish the forces created during corneringand through the theory, an estimation of the extensive tyre wear and extra fuelconsumption has been made. All due to the effects of the tyres not being inline with thecornering radius.

Idrott för alla? : Intresse och engagemang för breddverksamhet

  Aim. The aim of the study was to describe how nurses in home care experience to pursue palliative care in ordinary housing. Methods. The study had a descriptive design with qualitative approach and was carried out through semi-structured interviews with 14 nurses in home health care from two medium-sized Swedish municipalities. The material was analyzed with manifest and latent content analysis. Findings. The underlying theme that emerged in the study was: Working with palliative care in the patient´s own homes is positive but challenging. Informants describe among other things that they perceived palliative home care as meaningful and that relatives have a central role in the palliative home care since they are close to the patient around the clock. The stress that emerges from the heavy work load and the long geographic distances are described as strenuous and to affect the care in a negative way. Informants describe the home environment as challenging as it is often not adapted for care and the collaboration with the palliative team is described to be experienced as both positive and negative.

Religionsundervisning : - Genom vilka pedagogiska metoder

AbstractMy feature career as a teacher, for the early years of compulsory school, makes it interesting to finding out of how teaching religion can be donned. I am interested in what methods can be used for teaching religion That?s why my purpose aims to find out how five different teachers, of the early ages, works and what methods they use while teaching religion. My issue for this composition is: what methods, or to a point - methods supported by different teaching models, can be used for studying religion in compulsory school? Empirical and specialized literature points in the direction fore methods like storytelling, load reading, drama, group works, independent searching of information, working books and so on.

En tung börda på amfibieskyttesoldatens axlar? : Eller har rörligheten varit prioriterad?

Bakgrunden till studien är att vikten på den enskilda soldaten ökar allt mer vilket reducerar rörligheten. Om soldaten bär för tungt ökar risken för att verkan inte kan avges på rätt plats i rätt tid på grund av minskad rörlighet. Terrängen som amfibiesoldaten verkar i medför att stor del av striden sker till fots vilket torde betyda att rörligheten borde vara prioriterat för soldaten. Syftet med uppsatsen är att undersöka om rörlighet har varit prioriterat, för en amfibieskyttesoldat när den bedriver strid till fots, gentemot vikten på och plutonens anpassning av verkans- och skyddsutrustning. Metoden som använts är en jämförelse mellan amfibieskyttesoldatens olika utrustningsalternativ med de vikter som fastställts i författarens analysverktyg som utgår från de amerikanska doktrinerna.

Utrustning för automatmontering av ackumulator

This report deals with an exam report written by Olle Hjalmarsson and Thomas Likar, students at Högskolan i Halmstad. The project was carried out for Haldex Traction AB in Landskrona whose business consist of manufacturing automatic all wheel drive systems (AWD-system). These systems consist of a plate clutch which activates all four wheels of a 4-wheel driven vehicle. An important component in these clutches is the accumulator which basically consists of a piston under the load of a spring which creates an oil pressure with the help of an electric motor used for actuating the clutch.At Haldex difficulties has been experienced regarding the assembly of the accumulator parts due to the small tolerances between the piston and the hole of the accumulator in the cast aluminium housing. Attempts have been made to assemble the parts in existing robot cells.

Tidspress och ekonomiskt risktagande

Stress and time pressure is more present in todays labor markets. In financial markets a securities broker is forced to take decisions on investments under high cognitive load and under extreme time pressure. The research of decision under risk gained new ground with the development of the prospect theory and gave us new insights to the decision making of men. Prospect theory has shown that people are risk seekers when dealing with loss decisions and risk avert when dealing with profit decisions. The value function are defined over gains and losses.

Analys av lageregenskaper utifrån mätningar i testrigg

Vertical hydropower units has a rotating mass of up to 1000 tons. For the generator and turbine to work well the rotating system is required to be centered in relation to the surrounding structure. This is achieved by means of radial bearings. The dynamic characteristics of these bearings have a strong impact on the overall rotational dynamics of the total system and thus influence the vibrations in the unit. At Vattenfall Research & Development in Älvkarleby ongoing research is taking place on how the bearing parameters should be represented in the rotor dynamic calculations.

ARES is a simulation tool used in the desktop environment for simulations and calculations of the JAS 39 Gripen fighter and other aircraft. ARES stands for ?Aircraft Rigid body Engineering Simulation?. To work with these pilot models has been both time-consuming and inefficient.

Work-life balance och verkstadschefer

En hel del tidigare forskning tyder på att ha en balans mellan arbetsliv och privatliv är viktigt för att uppleva ett psykiskt välmående samt för att kunna prestera bra på arbetsplatsen. Då verkstadschefer på ett industriföretag genomgår ett stort förändringsarbete undersöktes hur fem manliga chefer upplevde sin balans mellan privatliv och arbetsliv. Delsyften med studien var att undersöka hur chefens roll i privatlivet påverkade balansen, i vilken grad stöd hemifrån påverkade balansen samt vilka konsekvenser en balans eller konflikt skulle kunna få. Studien genomfördes kvalitativt, med en semistrukturerad intervjuguide, där samtliga respondenter var påverkade av förändringsarbetet. Resultatet visade att det fanns verkstadschefer som upplevde en konflikt mellan arbetsliv och privatliv men även de som upplevde en balans.

Riskfaktorer för ländryggsbesvär beskrivs vara flerdimensionella, där nämns främst arbetsrelaterade och psykosociala faktorer. Poliser är en yrkesgrupp där arbetssjukdomar rapporteras vanligt förekommande oavsett kön. Trots det är polisers arbetssituation dåligt utforskad. Syftet med studien är att kartlägga upplevt hälsotillstånd och arbetssituation bland utryckningspoliser med fokus på ländryggsbesvär, som underlag för preventiva åtgärder.

Ny stamstation i Yttermalung för anslutning av vindkraft : Nätstudie av olika utföranden i normal- och reservdrift

Since 2004, wind power has had the largest installation of new capacity compared to other energy sources in Sweden. Accommodating new wind power may require strengthening or rebuilding of the existing grid in areas where the grid is already loaded to maximum capacity. This master thesis examine the possibility of a new 400/130 kV substation in Yttermalung, Sweden, with a connection to the two neighboring regional grids in Dalarna and Värmland owned by Fortum. This substation would provide a new connection point to the Swedish transmission system as well as an interconnection of the two, currently separated, regional grids. Different expansion scenarios where a substation with and without series compensation or a phase shifting transformer (PST) to control active power flow were studied.

Bestämning av dagvattenflöden i Knivstaåns avrinningsområde

The purpose of the thesis was to map the hydraulic load on the Knivsta river from stormwater runoff, and build a platform for further studies of pollution loads on the rivers ecosystems. New residential areas are planned to be built in Knivsta municipality and it will have an impact on stormwater flows to Knivsta river. To examine the impact this will have, simulations were made in the area as it stands today and after expansion work. The work includes calculation of flows from the populated areas but also from the catchment area around it consisting of woodlands and fields. Because of expected climatic changes which may affect rainfall, the simulations have been performed with different return periods for rainfall data.
