Surface water has become the most common source for raw water, when large quantities of groundwater often are inaccessible, and as surface water requires more treatment, simple, cheap and efficient process methods are necessary. Turbidity removal is essential for treatment of surface water and is often carried out with coagulation using metal salts as aluminium sulphate. This is used at Àguas de Mocambique (AdM), which provides the city of Maputo with water, but studies suggest that the metal salt can be replaced with a natural coagulant from the Moringa Oleifera tree.<br /> <br /> The Moringa Oleifera (MO) tree grows in tropical and subtropical regions around the world and its seeds have been used in drinking water treatment in small scale in Sudan and India for generations. The coagulant in the seeds is believed to be one or several proteins that act as a cationic polyelectrolyte. The soluble particles in the water attaches to the active agent, that binds them together creating large flocs in the water. Previous studies indicate that MO is an efficient coagulant and does not have an effect on most of the properties of the water, but an increase in COD has been noticed. Different ways of extracting the active agents are used and this will have an effect of the treatment efficiency.<br /> <br /> A comparison between MO and aluminium sulphate was conducted using jar test. The optimum dosage of the coagulant was investigated for different levels of turbidity, and monitoring of the properties of the water was performed. Use of MO together with roughing filter, and the possibilities to use MO at AdM was also investigated.<br /> <br /> Most efficient treatment was found when using aluminium sulphate for all levels of turbidity but the coagulant had an effect on pH and alkalinity. MO had no effect on measured parameters and was found to be most efficient at high raw water turbidity. MO extracted with tap water gave a better treatment than the MO extracted with distilled water or oil, but neither had an impact on the characteristics of the water. A prolonged sedimentation time together with MO improved the treatment and the experiment with roughing filters was successful. Treatment with MO and roughing filter led to a more efficient treatment compared to aluminium sulphate and roughing filter.<br /> <br /> Moringa is found to be a sustainable, cheap solution for coagulation in drinking water treatment. It is not considered possible to replace aluminium sulphate at AdM with MO at present time, but might be in the future. No current plantations of MO are located in the Maputo area and a stable and secure access to seeds is necessary. For best results MO is to be used together with roughing filters, which, will require reconstruction and investments at AdM. The possibilities of using MO at small scale treatment plants together with roughing filters are good, and provides a realistic alternative to conventional methods, presuming that an adequate amount of plantations are established. http://lup.lub.lu.se/student-papers/record/1317316/file/1317317.pdf application/pdf 990504 no 2008 eng Moringa Oleifera Environmental studies Miljöstudier aluminium sulphate drinking water treatment Earth and Environmental Sciences 1101-9824 08/5003 1317316 2008-05-22T00:00:00+02:00 2019-03-27T10:35:40+01:00 2008-01-01T00:00:00+01:00 1 info:srw/schema/1/mods-v3.3xml studentPublicationsH2 Nils Johansson author Håkan Frantzich supervisor professor Lars Jensen supervisor Risk Management and Safety Engineering (M.Sc.Eng.) v1000311 department Division of Fire Safety Engineering v1000219 department Division of Risk Management and Societal Safety v1000224 department This masters thesis deals with smoke spread via ventilation systems.

A second aim of this thesis is to investigate how frequently occurring smoke spread via ventilation systems in Swedish buildings are. A third aim is to investigate how uncertainties in input variables to smoke spread calculations will affect the result of calculation. To be able to do this the most important input variables are identified and analysed. A calculation example is also conducted in the end of the thesis where a supply and exhaust system is analysed with an event tree and the computer program PFS. http://lup.lub.lu.se/student-papers/record/1317522/file/1317523.pdf application/pdf 702782 no 2006 swe osäkerhetsanalys osäkerheter incidents international codes.

Land reclamation has been an option in many maritime countries, including in Malaysia to overcome this problem. Tanjung Tokong Land Reclamation Project is an ongoing development project in Penang, Malaysia, where housing and commercial properties are constructed on the reclaimed area. The main objective of this study is to determine the effect of the Tanjung Tokong Land Reclamation project on the coastal areas regarding wave transformation, sediment transport, and coastal evolution. However, the effects on the environment and ecosystems are not included. Initially, general coastal processes in Penang were investigated and the project background described to get an overview of the study area. Then, a numerical model, EBED, was employed to simulate the nearshore wave transformation in the specified study area for four different scenarios of incident wave heights and wave directions before and after the project. Based on the EBED simulation results, changes in the wave transformation pattern after the land reclamation project were assessed. Wave transformation for incoming waves from the west was more significantly affected compared to incoming waves from the north and east by the land reclamation. Local sediment transport rates also changed after the project, mainly because of the influence on the incoming local wave height and direction. However, there were no significant differences concerning the local sediment transport direction along the coast after project. The effects on the coastal evolution of the project were increased erosion for waves coming from the west and increased accumulation for waves coming from the east side for particular stretches of coastline in the vicinity of the project site. As an overall conclusion, this study showed that the Tanjung Tokong Land Reclamation Project have an impact on the wave transformation, sediment transport, and evolution of the coastal areas in the vicinity of the land reclamation, but there is limited impact some distance away from the project site. http://lup.lub.lu.se/student-papers/record/1317634/file/1317635.pdf application/pdf 3566960 no 2008 eng wave transformation sediment transport land reclamation coastal evolution EBED Model Väg- och vattenbyggnadsteknik soil mechanics offshore technology hydraulic engineering Civil engineering Technology and Engineering 1101-9824 08/5004 1317634 2008-02-19T00:00:00+01:00 2019-03-27T10:29:16+01:00 2008-01-01T00:00:00+01:00 4 info:srw/schema/1/mods-v3.3xml studentPublicationsH2 Carl Nelin Jensen author Gunno Renman supervisor Division of Water Resources Engineering v1000225 department To avoid eutrofication and excessive algal bloms it is necessary to reduce the phosphorus contents in wastewater.<br /> <br /> Previous wastewater treatment systems often have a good process for phosphorus reduction but in general not the<br /> <br /> ability to recycle the material and phosphorus for further utilisation after its use in wastewater treatment.<br /> <br /> Polonite® is a material with large content of calciumoxide which makes it very reactive and an effective sorbent of<br /> <br /> phosphorus. It has also been stated that when loaded with nutrients like phosphorus, Polonite® can be used as<br /> <br /> fertilizer for plants.<br /> <br /> In this thesis a prototype developed by Bioptech AB was tested to see if it can remove phosphorus from wastewater<br /> <br /> with fine grain size Polonite® as sorbent and then retain the phosphorus loaded Polonite® for further use, for<br /> <br /> example as fertilizer in agriculture. Unlike previous wastewater treatment systems the used material och retained<br /> <br /> phosphorus would then be recycled. If this can be achieved it would complete the environmental cycle for<br /> <br /> phosphorus which is important for a sustainable and healthy ecosystem.<br /> <br /> The prototype was setup at the wastewater treatment plant in Skokloster, north of Stockholm. The prototype is<br /> <br /> developed so that it first can create the right circumstances for Polonite® to come in contact with the wastewater and<br /> <br /> reduce fosfor contents. Then it can retain the used material for further use by separating it from the solution.<br /> <br /> Separation is made with a drumfilter and sedimentationtank. The wastewater was taken from after the mechanical<br /> <br /> and biological treatment since tests in the laboratory indicated that the process could be interfered and less effective<br /> <br /> with high BOD and organic matter.<br /> <br /> As expected high pH was necessary to get a succesful reduction of phosphorus. When pH is over 10, the reduction<br /> <br /> of phosphorus is more then 95% after 5 minutes. 4kg Polonite®/m3 had to be added for these results. The sorption<br /> <br /> capacity for this amount is more than sufficient. The process needs to be more effective, to much material is needed<br /> <br /> to get good reduction of phosphorus besides the fertilizer potential can probably not be guaranteed with so little<br /> <br /> phosphorus attached to the Polonite®.<br /> <br /> The outgoing water was checked for Polonite® material and the retention was assumed to be over 90%. Even better<br /> <br /> retention could be achieved with a larger sedimentation tank and smoother outlet of the water stream. http://lup.lub.lu.se/student-papers/record/1320871/file/1320872.pdf application/pdf 738104 no 2008 eng offshore technology hydraulic engineering Civil engineering Miljöstudier Environmental studies Recycling of sorbent and nutrient Polonite® Wastewater treatment Phosphorus reduction soil mechanics Väg- och vattenbyggnadsteknik Earth and Environmental Sciences Technology and Engineering 1101-9824 08/5012 http://lup.lub.lu.se/student-papers/record/1320871/file/1411209.pdf application/pdf yes 1320871 2008-11-07T00:00:00+01:00 2019-03-27T10:44:12+01:00 2008-01-01T00:00:00+01:00 5 info:srw/schema/1/mods-v3.3xml studentPublicationsH2 Jonas Linnersund author Erik Mårtensson author Professor Magnus Larson supervisor Division of Water Resources Engineering v1000225 department Bardawil Lagoon, a natural lagoon located on the northern coast of the Sinai Peninsula, Egypt, there are three inlets of which two are man-made connecting the lagoon with the Mediterranean Sea. The inlets are subjected to changes in morphology, due to sediment transport, over time and this may lead to degrees of closure of either inlet. The sediment transport is governed by longshore currents and the sediments originate from the eroding Nile delta. Inlet closure adversely affects the lagoon water quality which will have a detrimental effect on the ecosystem.<br /> <br /> In this dissertation the dominant coastal processes governing the water exchange between the lagoon and the Mediterranean are studied. Finite element conceptual computer models are applied to simulate and investigate the hydrodynamics of the inlets and the lagoon itself. Two types of models are applied within the Surface Modelling System (SMS) software; ADCIRC, a regional tidal model and CMS-Flow, a local circulation model. In order to estimate the exchange rate of the lagoon two methods are utilized; based on net intertidal volume and cross sectional flow through the inlets. The methods show a high degree of correlation. The renewal time was estimated to 9.0 days, which is equivalent to a daily replaced volume of 53?106 m3. Tidal forcing governs the water exchange while wind is responsible for the internal circulation. http://lup.lub.lu.se/student-papers/record/1320904/file/1320905.pdf application/pdf 5321165 no http://lup.lub.lu.se/student-papers/record/1320904/file/1320906.pdf application/pdf 224035 no 2008 eng Fysisk geografi climatology cartography Environmental studies Miljöstudier wind water balance tide sediment transport salt balance renewal time net intertidal volume finite element internal circulation ADCIRC CMS-Flow Bardawil Lagoon Physical geography pedology geomorphology geomorfologi marklära kartografi klimatologi Technological sciences Teknik Earth and Environmental Sciences Technology and Engineering 1101-9824 08/5010 1320904 2008-11-20T00:00:00+01:00 2019-03-27T10:32:10+01:00 2008-01-01T00:00:00+01:00 6 info:srw/schema/1/mods-v3.3xml studentPublicationsH2 Joakim Almén author Anders Rosqvist author Ulf Paulsson supervisor Risk Management and Safety Engineering (M.Sc.Eng.) v1000311 department Division of Fire Safety Engineering v1000219 department Division of Risk Management and Societal Safety v1000224 department Major businesses today involves complex supply chains with world-wide sourcing and marketing which create new risks for both the individual enterprise and the society at large. Supply chain disruptions are seen as the primary threat to a company&#39;s revenue driver. To be able to cope with undesired events, companies need to review their business continuity management (BCM).<br /> <br /> To increase the knowledge of effective BCM, this thesis develops and presents a model for evaluating the level of BCM within a company, The BCM Evaluation Model. The model is a self-assessment questionnaire to be used at site level which can give management and insurance companies an indication of what needs to be improved to reduce the potential negative business profit impact from a disruption somewhere in the supply chain.<br /> <br /> The study involves a lens with factors based on a literature survey. Documented cases were then examined through the lens to find key factors for effective BCM. The model was validated through a test on six company affiliates together with expert opinions. http://lup.lub.lu.se/student-papers/record/1320910/file/1320911.pdf application/pdf 7816265 no 2008 eng crisis preparedness enterprise risk management business recovery crisis management emergency response BCM Evaluation Model Business continuity management business continuity planning crisis risk supply chain disruption Risk Management and Safety engineering Riskhantering Technology and Engineering 1402-3504 5265 1320910 2008-11-22T00:00:00+01:00 2020-12-03T14:26:03+01:00 2008-01-01T00:00:00+01:00 7 info:srw/schema/1/mods-v3.3xml studentPublicationsH2 Lisa Larsson author Hanna Sellehed author Anders Jacobsson supervisor Risk Management and Safety Engineering (M.Sc.Eng.) v1000311 department Division of Fire Safety Engineering v1000219 department Division of Risk Management and Societal Safety v1000224 department This master thesis is developed based on the desire of the water and sewage department in the municipality of Karlskrona. The department, which vouches for the quality of produced drinking water and sewage cleaning, was in need of help dealing with risk analysis.<br /> <br /> The water and sewage department is obliged to identify and assess risks according to Swedish legislation. However, no guides for this purpose regarding safety, health, environment and quality were available. The aim of this report was to accomplish a guideline for the performance of risk analysis within water and sewage plants. If the guideline is used, the requirements in the legislation will be obtained. Even other advantages can be expected. A risk analysis helps identifying needs for improvement.

Global issues, like Earth warming, or regional planned uses of water, e.g. irrigation, demand an increase in accuracy and coverage of different components of the water balance. Precipitation and the water loss from vegetation and soil, called Evapotranspiration (ET), are main components in the water balance equation. While precipitation, the main input in water balance models, is easily measured, ET, the major loss, is not. Current and most used methods are accurate but limited in time and mostly in space. Extended ET measurements are needed to manage water resources at regional or broader scales with reasonable accuracy. The use of remote sensing has been tested for last two decades and is still subject to extended research to overcome definitively this problem. Present work compares results of application of a simplified version of residual of energy budget, Roerink´s S-SEBI model, to calculate ET using three sensors with high (AHS), medium (ASTER) and low resolution (NOAA´s AVHRR) at Barrax field, Spain, on 18th July 2004. Its application basically stands for energy balance equation using visible and near infra-red radiation measurements coming in and out of the surface-vegetation-atmosphere system. Incoming short and long wave radiation were measured on field at ?Las Tiesas? lysimetric station, which was used as reference, and the remaining variables were measured instantaneously at sensors overpasses and then extrapolated to daily values. Jackson empirical model is also used to contrast results. Albedo, temperature and emissivity were retrieved from sensors and used to calculate Evaporative Fraction, net radiation, geothermal flux and vegetation indices NDVI and MSAVI. Once all variables are calculated the S-SEBI is applied and the instantaneous ET value is extrapolated to daily value in mm/day at the chosen area. Results showed a good correlation, for most of variables, between AHS and ASTER and acceptable error (around 10%) for the higher resolution sensor. Meanwhile AVHRR did not show good results but, anyhow, it could still represent some potential use in large and homogeneous areas with less accuracy demand assessments or as complementary information for water resource management at regional or even global scales. http://lup.lub.lu.se/student-papers/record/1320387/file/1320388.pdf application/pdf 2371670 no 2008 eng geomorphology Physical geography Evapotranspiration and semote sensing S-SEBI Model Water balance Environmental Satellite images applications Environmental studies Miljöstudier Natural science climatology cartography Naturvetenskap Hydrogeology geographical and geological engineering Hydrogeologi teknisk geografi teknisk geologi pedology Fysisk geografi geomorfologi marklära kartografi klimatologi Earth and Environmental Sciences 1101-9824 07/5016 1320387 2008-04-24T00:00:00+02:00 2019-03-27T10:39:46+01:00 2008-01-01T00:00:00+01:00 9 info:srw/schema/1/mods-v3.3xml studentPublicationsH2 Karl Hedvall author Anders Jacobsson supervisor Risk Management and Safety Engineering (M.Sc.Eng.) v1000311 department Division of Fire Safety Engineering v1000219 department Division of Risk Management and Societal Safety v1000224 department In this report a systematic working procedure for risk classification of processing equipment from a maintenance point of view is described.

This is usually achieved by the estimation of the hydrological and meteorological characteristics of the basin using observed data to carry out statistical estimates or for use in hydrological models. Hydrological and meteorological data for the Mefou sub basin in Cameroon were collected to analyse the rainfall-runoff pattern and estimate the potential runoff volume from the sub basin. The data included daily series of rainfall, runoff, temperature and evapotranspiration for some periods in which data was available for ten meteorological stations and one hydrological station within or near to the catchment. Data was available for only one rainfall station at Yaoundé and one runoff station at Nsimalen directly located within the sub basin. The rainfall station had data for seven years from 1976 to 1982 while the runoff station had data for five years from 1976 to 1977 and 1984 to 1986. However, a nearby rainfall station at Sangmelima had observed data for 13 years from 1975 to 1987 which could be used as a replacement station for Yaoundé. Simple statistical and graphical methods were used to analyse and compare the data from the Yaoundé and Sangmelima stations to determine a correlation between them in order to extend the Yaoundé data to 10 years at least. Similarly simple statistical and graphical methods were used to determine a monthly and annual relationship between the rainfall and runoff data of the Yaoundé station and the Nsimalen station. These relationships were used to extend the monthly and annual runoff to the intermediate years without data from 1978 to 1983 and 1987. It was necessary to extend this data to at least 10 years in order to increase the possibility of including both wet and dry periods of the sub basin in the hydrological estimates. The rainfall and runoff data was eventually extended to 12 years from 1976 to 1987. After extending the data the average annual runoff volume of the entire sub basin was estimated from the analysed data. This runoff was found to be within the range of previous estimates carried out in the sub basin though the volume is inadequate to satisfy the water resources requirements of the sub basin. The data was then used in the Swedish HBV rainfall-runoff model which is a semi distributed conceptual model to estimate catchment parameters, forecast the values for some years with missing data and compare results from the statistical and graphical methods. Some future climate scenarios were also simulated in the model and the results were also in line with other previous studies carried out in the bigger catchment within which the Mefou is a sub catchment. The difficulties in making hydrological and meteorological estimates in catchments with little or no data are highlighted by this project and recommendations are made towards facilitating the carrying out of satisfactory water resources studies in other sub catchments with similar limitations. http://lup.lub.lu.se/student-papers/record/1319465/file/1319466.pdf application/pdf 1119290 no 2008 eng offshore technology Limited data Swedish HBV model with limited data Rainfall-runoff estimates Environmental studies Miljöstudier Väg- och vattenbyggnadsteknik hydraulic engineering Civil engineering soil mechanics Technology and Engineering Earth and Environmental Sciences 1101-9824 08/5001 1319465 2008-01-25T00:00:00+01:00 2019-03-27T10:37:05+01:00 2008-01-01T00:00:00+01:00 12 info:srw/schema/1/mods-v3.3xml studentPublicationsM2 David Carvajal author Ole Elgström supervisor Department of Political Science v1000693 department This essay is about the Northern Ireland Conflict and the Belfast Agreement.

Then the focus is on the nationalist society where the opinion towards the agreement have been positive but where the power change from SDLP to Sinn Féin depend on the changes of further concessions. Third the negotiators strategies are analyzed. All this parts are constructed by the concept of win-sets. Later a small conclusion is made and a further discussion is made about the<br /> <br /> concept of win-set and two-Level Games.

The<br /> problem is largely due to the shift in agricultural practices. Farming methods have become more efficient<br /> during the last 300 years. Watercourses have been straightened out and wetlands have been reduced to<br /> increase agricultural landuse. Since the end of the 1940s, fertilization has increased dramatically. These<br /> factors have caused unnatural eutrophication and algae blooming in watercourses, lakes and ultimately the<br /> sea. In Sweden, the government has determined to reduce the nitrogen discharge by 50 percent by the year<br /> 2000. In order to accomplish this reduction companies and authorities have been assigned to find suitable<br /> reduction measures.<br /> The soils in Scania are among the most nutritious ones in Sweden. This along with high fertilization makes<br /> Scania a high risk area. In 1991, Ekologgruppen was assigned by the government to investigate the drainage<br /> area of the stream of Kävlingeån. Tolångaån constitutes a part of Kävlingeån and measurements of the<br /> water quality have been taking place since 1976 at Tolånga. As there were plenty of data available in this<br /> area the decision was made, in agreement with the county administrative board in Malmö, to study<br /> Tolångaån. The fact that the water finally reaches the lake of Vombsjön highlights the importance of<br /> establishing a good quality of the water. The lake serves as a source of water supply and provides parts of<br /> Scania with drinking-water. The study focuses on investigating the nitrogen situation in the stream and<br /> comparing measured values with simulated ones. Nitrogen simulation models are usefool tools, when<br /> making predictions of leakage. The model used in this study is based on the SOILN-model and simulates<br /> nitrogen dynamics and losses in the agricultural soil of the study area. SOILN was developed in the mid 80s<br /> and simulated leakage has shown good accuracy with observed measurements. The simulation was made<br /> over a ten-year period (1985-1994). The leakage from four different crops were simulated; ley, seed, rootcrops<br /> and oil plant. In addition, the effect of one measure to reduce leakage was simulated, the use of catch<br /> cropping. To illustrate the effect of the climate, one year with low precipitation (1989) and one year with<br /> high precipitation (1994) were compared.<br /> A trend analysis shows that nitrogen content in the watercourse has been fairly constant during the last two<br /> decades. However, the nitrogen content is far too high to be acceptable. When comparing measured values<br /> with simulated values adjustments had to be made. The simulated leakage was too high and a model<br /> parameter was evaluated in order to adjust the leakage. In spite of this, simulated values did not agree<br /> totally with measured values. This is probably due to the fact that the ground water model which is<br /> connected to the nitrogen model is too simple. When comparing the leakage caused by different crops, it<br /> turned out that ley had the best nitrogen uptake. Seed and root-crops were not as efficient as ley when it<br /> comes to assimlate nitrogen and contributed to most of the leakage. When simulating the effect of<br /> catchcrops it was possible to reduce nitrogen leakage by 30 percent. Previous studies have shown that<br /> catchcrop may reduce nitrogen leakage by 60 percent. The results from Tolånga and the simulation showed<br /> that precipitation is the parameter that has the greatest influence on the nitrogen leakage. Under de senaste 300 åren har jordbrukslandskapet i Sverige genomgått stora förändringar. I början av 1900-talet introducerades konstgödslet och efter andra världskriget ökade gödslingen dramatiskt i syfte att maximera produktionen. Detta har lett till att överskottet av kväve har spolats ut i vattendragen. I detta arbete har stor vikt lagts vid att skapa en egen kvävemodell i syfte att simulera kväveläckaget från jordbruksmarken i Tolångaåns dräneringsområde. Populärvetenskaplig sammanfattning: Under de senaste 300 åren har jordbrukslandskapet i Sverige genomgått stora förändringar. Detta började med att bönderna i slutet av 1600-talet erhöll en stor del av adelns jord. De fick således förvalta sin egen vinst, vilket resulterade i en rad nyodlingar och tekniska hjälpmedel. I början av 1900-talet introducerades konstgödslet och efter andra världskriget ökade gödslingen dramatiskt i syfte att maximera produktionen. I detta skede införde många gårdar kreaturslös drift vilket gjorde att den tidigare balansen mellan nötkreatur, vall (bete) och spannmålsproduktion inte längre fanns kvar. Följden blev att vallarealen minskade och att bönderna köpte gödslet utifrån, ofta i form av konstgödsel. För att erhålla så mycket jordbruksmark som möjligt har rationaliseringar av olika slag genomförts av jordbrukslandskapet. Olika typer av odlingshinder såsom våtmarker, vattendrag och olika form av vegetation har tagits bort. Långa sträckor av tidigare öppna vattendrag och dräneringsdiken har lagts i kulvertar och rör. Detta har lett till att det kväve (i form av stallgödsel eller konstgödsel) som inte tas upp av grödorna spolas ut i vattendragen och slutligen ut till våra sjöar och hav<br /> <br /> För att bestämma hur mycket kväve som tillförs vattendragen utförs mätningar i olika forskningsprojekt runt om i landet. Dessa fältmätningar är ofta avancerade och kostnadskrävande, vilket omöjliggör övervakning av stor delar av den svenska åkermarken. Modellering, med vilket kvävets dynamik samt förluster kan simuleras, utgör därför ett bra alternativ till fältmätningar. I detta arbete har stor vikt lagts vid att skapa en egen kvävemodell i syfte att simulera kväveläckaget från jordbruksmarken i Tolångaåns dräneringsområde. Tolångaån utgör ett tillflöde till Vombsjön och ingår i Kävlingeåns dräneringsområde. Modellen tillverkades genom att studera kvävets kretslopp och genom att ta reda på hur mycket gödsel samt atmosfärisk kvävedepostition som tillförs marken. Kvävet i marken är lagrat i två former; oorganiskt (mineraliskt) eller organiskt. Det oorganiska kvävet är lagrat i form av ammonium och nitrat. Omfördelning av kväve sker hela tiden mellan de olika magasinen i marken och detta styrs av hur stor mängd lättillgänglig organisk substans (kol) som finns. Eftersom kolet har en avgörande betydelse för kvävets omvandling i marken kopplades en separat kolmodell till kvävemodellen. Markvattnet spelar också en central roll när det gäller kväveutlakningen, eftersom kvävet (nitrat) följer med det perkolerande vattnet ut till vattendragen. Simuleringen av mängden markvatten gjordes därför också i en separat modell.<br /> <br /> Kvävesituationen i Tolångaån studerades för åren 1976-1997 och en trendanalys av uppmätta kvävehalter visade att kvävehalterna har varit relativt konstanta under hela mätperioden. Modellen ovan applicerades på det uträknade dräneringsområdet runt Tolångaån. Uppmätta och simulerade kvävetransporter visade sig stämma bra överens vissa år medan skillnaden var stor andra år. Skillnader kan exempelvis bero på att det i verkligheten kan ha förekommit felmätningar eller punktutsläpp av kväve, vilket modellen inte kan ta hänsyn till. Hur stort kväveläckaget blir beror på många faktorer såsom klimat, jordart, vilken gröda som odlas, tid på året och framför allt på nederbördsmängd. För att se hur stor effekt klimatet utgör jämfördes ett nederbördsfattigt år (1989) och ett nederbördsrikt år (1994). Omfattande nederbörd tenderar att laka ut stora mängder kväve, vilket bekräftades vid jämförelse av de båda åren. Eftersom olika grödor har olika kvävebehov och således orsakar olika mycket utlakning, undersöktes även hur stor andel de olika grödorna står för i området. Grödorna delades in i vall, oljeväxter, rotfrukter och säd. Vall och oljeväxter visade sig enligt simuleringsresultaten stå för den minsta utlakningen. De är sålunda bra att odla i områden som har höga utlakningssiffror. Rotfrukter och säd är däremot inte alls lika effektiva att ta upp kväve och högre utlakningssiffror erhålls. http://lup.lub.lu.se/student-papers/record/1330046/file/1330047.pdf application/pdf 2639465 no 1999 swe agricultural hydrology soil science miljöstudier environmental studies jordbruk jordbruksutsläpp environment miljö kväve nitrogen geografisk informationsbehandling lantbrukshydrologi marklära physical geography geomorphology pedology cartography climatology naturgeografi geomorfologi kartografi klimatologi Agriculture and Food Sciences Earth and Environmental Sciences 55 B 1330046 2005-05-25T00:00:00+02:00 2023-03-10T13:41:32+01:00 1999-01-01T00:00:00+01:00 14 info:srw/schema/1/mods-v3.3xml studentPublicationsH1 Claes-Magnus Bernson author Michael Azar supervisor Division of History of Ideas and Sciences v1000078 department This essay seeks to articulate how one should understand Adorno´s perspective on Kant.

Med teorin Differentiering och Konsolidering (Diff-Con) som utgångspunkt, testades hypoteser om en skillnad i konsolidering av ett beslut mellan deltagare med höga respektive låga tendenser till maximerande, subjektivt välbefinnande (SVB) och antal övervägda alternativ i en beslutssituation. 56 deltagare delades in i grupper beroende på hur många beslutsalternativ de valde att överväga och hur de skattade sig själv i tendenser till maximerande och SVB, och bedömde under två tillfällen, med två veckors mellanrum, beslutsalternativ holistiskt och på egenskaper. Resultatet stödde tidigare forskning inom Diff-Con genom en konsolideringseffekt för samtliga deltagare på den holistiska bedömningen av beslutet. Inga signifikanta skillnader hittades mellan grupperna förutom på den mest betydelsefulla egenskapen mellan personer som valt få respektive många antal alternativ att överväga mellan i en beslutssituation. Här separerade de deltagare som valt många alternativ att överväga mellan (4 till 5 alternativ) det valda alternativet mer från det bäst konkurrerande alternativet än deltagare som valt få alternativ (2 till 3 alternativ). http://lup.lub.lu.se/student-papers/record/1323889/file/1323890.pdf application/pdf 398618 yes 2007 swe beslutsfattande diff con maximerande subjektivt välbefinnande valmöjligheter Social sciences Samhällsvetenskaper Applied and experimental psychology Tillämpad och experimentell psykologi Social Sciences 1323889 2007-01-26T00:00:00+01:00 2021-11-15T11:36:56+01:00 2007-01-01T00:00:00+01:00 17 info:srw/schema/1/mods-v3.3xml studentPublicationsH2 Lina Holgersson author Lars Fredholm supervisor Jonas Röjås supervisor Division of Fire Safety Engineering v1000219 department Risk Management and Safety Engineering (M.Sc.Eng.) v1000311 department Division of Risk Management and Societal Safety v1000224 department Municipal safety work is an issue frequently discussed.

In Borlänge municipality there has been no sanctioned proposal for a program. This report presents the problems found and gives proposals for improvements in the future safety work. The guiding words should be unambiguousness, able to control and not too complicated. Feedback and evaluation are other important parts.
