Outages in the electric grid can be costly for society. Because of this, reliability is one of the parameters used to regulate network companies. Reliability in electrical grids can be measured with SAIDI, system average interruption duration index, which for Fortum Distribution has increased in Stockholm?s distribution network (11 kV) in the early 2000?s.By using outage data for Stockholm from 2011-2013, sets of parameters to be used for reliability calculations in the network information program Tekla NIS were derived. Two different options for investment were then analysed: changing old cables with high fault frequencies, and installing automatic switching in distribution substations.

The implementation of large IT-systems is a complex area where many aspects have to be taken into account.KSU, Kärnkraftssäkerhet och Utbildning AB, is a small company in the Vattenfall group that is increasingly being urged to implement SAP, one of the largest ERP-systems on the market. Vattenfalls purpose with SAP is to centralize certain processes within economy that are common to all the companies in the group, this to gain benefits with economics of scale. However, KSU is not convinced that SAP is a suitable system and that the common processes apply to them.The purpose of this degree project is to investigate if SAP is a suitable system and if KSU will benefit from a transition to SAP. Three perspectives were applied to further specify important areas of the main question. From a technical point of view KSU:s demands on a system was mapped against SAP.

Sweden is considered to have one of the world's highest animal welfare standards in agriculture. Despite this, there are shortcomings in animal husbandry. One example is overcrowding, which is a way to increase stock size without making costly investments in the buildings. It can be carried out systematically to increase profitability or due to, for example uneven calving during the year. The European Commission criticizes the fact that stocking density is not controlled under Swedish welfare inspections.

Abstract Background Todays guidelines for advanced CPR emphasize chest compressions with good quality and early defibrillation. Prehospital CPR performed by ambulance crew, an automated external defibrillator (AED) is used. The AED analyzes the heart rhythm and the performer is following the advice to chock the heart or not, given by the AED. During on-going CPR there are sequences when no chest compression is performed known as hands-off time. Hands-off time includes the time for the AED to analyze the heart rhythm and the time when advice is given to the crew.

The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.

There are around 855 000 on-site sewage systems in Sweden and some 1 800 of these are located in the municipality of Sigtuna. The Sigtuna local authority has set the goal that all sewage systems with insufficient function should be improved before the end of year 2010. A malfunctioning on-site sewage system may cause three main problems: spreading of diseases, discharge of eutrophicating compounds and wastage of resources. The municipality strives to reduce these problems already at the stage of granting permits for installation of on site sanitation systems. The municipality has recently adopted new guidelines, which demands certain minimum reductions for different compounds. The guidelines also state that it is preferred that neighboring house-owners cooperate in jointly built and operated sewage systems and that the system should be able to recycle plant nutrients.

Blekinge Hospital suffers from a budget shortage of 100 million SEK, while the government now requires that hospitals will no longer be running a deficit. Blekinge Hospital will then use their limited resources to survive in the future and the activity must be enhanced in order to keep costs low without having to lay off personnel. The idea is that the organisation should be more efficient with a more efficient resource usage. Performance measurement systems are important tools for achieving the policies set out within an organization, measuring and evaluating performance is a way to see where improvements in efficiency may be necessary in the business. Balanced Scorecard (BSC) is one of several measuring systems, where the focus is on measuring non-financial performances.

The demand for food, feed, fibre and fuel has increased in Uganda over the past 50 years due to population growth. Recurring extreme climate events such as drought and flooding, in combination with large-scale land degradation, have led to declining crop yields. Lack of equipment, money and socio-economic issues has contributed to low yields. However, the soils in Uganda have the potential to produce much higher yields than they do today. This study, which was carried out in April-June 2013 in Kkingo District, south-east Uganda, examined the effects of agroforestry on yield of cooking bananas in small-holder farming systems. Six farms practising agroforestry and six farms with no agroforestry, which were chosen in cooperation with the NGO Vi Agroforestry, were compared.

More frequent and intensified rainfalls are expected to occur due to climate change in the nearfuture. This together with a higher proportion of paved areas increases the pressure on today?sstorm water systems (Risinger, 2014; Boverket, 2013; Stahre, 2006). Traditional storm watersystems (i.e. underground pipe systems) have during last decades started to be questioned(Olshammar & Baresel, 2012).

The purpose of this degree project is to investigate how horse keepers reasons about horse keeping and how the horse keeping looks like today. It is interesting to compare modern horse keeping with ancien recommendations and how the horses were kept then to understand how much in the horse keeping today that is based on traditions instead of research and science. The degree project was based on data from interviews of 52 horse keepers in five different municipalities. All interviews have been based from the same questionaire about how there horses are kept today, what they think about different housing systems, how they think horses will be housed in the future and what problems they think are the biggest in horse keeping today. The results shows that single boxes indoors are the most frequently used housing system today.

The effectiveness of communication in the Swedish healthcare system context has long been the subject of debate. Issues stemming from usability, accessability and interpretation affect the lives of patients, and yet the vocal groups in the healthcare communication debate are patients and administrators, not healthcare professionals. With the advent of eHealth services and new demands being put forth on the ability of healthcare professionals' to handle increasingly numerous and innovative systems, it is of more importance than ever to understand the healthcare professionals' work context. This article is based on interviews with five healthcare professionals concerning their views on electronic health records (EHR), eHealth services, trends in healthcare services development in Sweden, as well as their views on the future of eHealth solutions and health information technology (HIT). Analysis of collected information shows an apprehension among healthcare professionals towards electronic communication, as well as a dissatisfaction with the usability of modern healthcare systems.

Article 4.1(h) in the Rome I regulation establishes which law that will be applicable on contracts concerning financial instruments concluded in multilateral systems. The main problem is that most contracts concluded within these systems have standard clauses which contain a clause on the applicable law. If this is the case, Article 3.1 in the Rome I Regulation is applicable instead. This problem makes it difficult to find a need for article 4.1(h) if it will only be applicable in exceptional cases. However, the legal position on this matter is still unclear since the Rome I Regulation has just been put into force.

The purpose of this project is to analyze earthing systems for houses. By practical measurements and theoretical analyzes consequences of possible faults, that can occur within the facility and in the low-voltage distribution network, is illustrated.  The reason for this project is that nowadays one has to arrange with a main equipotential bonding system for buildings. Apart from that, if necessary, bathrooms must be provided with a supplementary equipotential bonding system.The practical measurements verify that potential differences in facilities may be due to voltage drops in the PEN conductor between the origin of the electrical installation and the power transformer.Based on the theoretical analyzes of possible faults, it is considered that the requirement for  supplementary equipotential bonding systems for bathrooms in most cases can be questioned, when basic insulation, fault protection, residual current devise and main equipotential bonding system already provides an adequate level of protection.A PEN conductor loss may result in a situation where metallic parts attached to the equipotential bonding system starts working as earth electrodes. Equipotential bonding system may also increase the incidence of stray currents. If TN-C-S systems is provided with a local connection to earth a redundant system against PEN conductor loss is obtained.

At the end of 70s and the beginning of 80s, 18 terminals was built and used for chipping wood residue from clear cuttings. Most of the terminals was terminated before the 2000s but with the high oil- and energy prices that we can see today there might be a place for these terminals again. The goal with the study was to analyze and compare economical differences between 5 different logistical systems, collected data was used with a set of formulas. The systems include long range transport of slash, chips and bundles. Three of the systems include transport by lorry to industry the last two includes a terminal with access to train transport.

Småskalig mjölkproduktion är ett system som främjar regelbundna inkomster och spelar en viktig roll för att minska fattigdomen, ger anställningsmöjligheter och skapar välfärd samt säkrar en näringsrik livsmedelsförsörjning. Det finns cirka 2500 småskaliga mjölkbönder i Zambia men deras kunskap om bra mjölkningsrutiner och hygien är ofta dåliga. Bra skötselrutiner och mjölkningshygien är viktigt för att uppnå en god juverhälsa och mjölkproduktion, och för att inte förorena mjölken. Subklinisk mastit är en vanlig sjukdom bland mjölkkor, som medför förändrad sammansättning av mjölken och minskad mjölkproduktion vilket orsakar stora ekonomiska förluster. Syftet med denna studie var att undersöka skötselrutinerna, med fokus på mjölkningen, hos småskaliga mjölkbönder i tre olika områden i södra Zambia samt att undersöka om det fanns något samband mellan skötselfaktorerna och juverhälsan (subklinisk mastit).
