Control and comparison of various cleaning methods on restaurants in Södra RoslagenThe purpose of this report is to find out and analyze the efficiency of cleaning methods in restaurant kitchens. The investigation was carried out through unannounced inspections at 89 restaurants in Södra Roslagen (municipality of Danderyd, Täby and Vaxholm). ATP-measuring was done on a plate, a knife, a bench surface and a cutting board. The ATP-method measured the amount of food residue on equipment and working surfaces after cleaning, with a luminometer and swabs. Restaurant staffs were asked to describe in detail how and when the last cleaning was carried out on the surface.

Agricultural soils constitute the base in human food production and soil content of organic matter and plant nutrients together with soil microbial activity are all important parameters for high crop yield of good quality. These parameters are dependant on proper fertilization.Anaerobic digestion of organic wastes for biogas production generates a liquid residue called biogas residue (BR). It contains organic material and plant nutrients which makes ita potential fertilizer for arable cropping. However, it also contains heavy metals and toxic organic compounds and it is therefore in need of evaluation before usage.Microbial tests were performed aiming to evaluate the agronomic traits of four different BR and to find a viable procedure for evaluating slurry fertilizers. Two experiments where soil respiration and soil potential denitrification activity (PDA) was measured at fertilizer addition were performed.

Sudoku solvers are a widely researched topic among mathematicians and computer scientists. This report investigates the differences in execution time and time complexity between backtracking and human strategies for classes with 17-21 clues. Backtracking is compared to our implementation of human strategies with test data that contains 99 Sudoku puzzles for each class. The study shows that the execution time and time complexity is improved for human strategies compared to backtracking for each class. The conclusion shows that it is always favorable to implement the human strategies investigated in the report. .

The primary function of a mixer is to keep a fluid in constant motion. All mixing applicationsrequire varying degrees of small-scale turbulence and bulk flow. The performance of asubmersible mixer is measured by the thrust that it produces, while the strength of the bulkflow is dependent on the total amount of installed thrust.In a mixer, the fluid quickly flows past the propeller, and as a result, the current is mainlyaxial. The fluid will also obtain a rotating velocity, or a swirl, though this is significantly lessthan that of the propeller. During the process, the total amount of energy increases in the formof static pressure and kinetic energy.

The purpose of this report is to examine the possibilities to decrease the number of insects and other pathogens in a crop of pak choi (Brassica rapa), grown with different types of cover and living mulches. Included in the report is a study of literature where amongst others, a summary on the vegetable pak choi and theories of living mulches and different kind of covers are to be found. To examine the amount of predators in the field, traps were used. During the autumn 2002 the tests were conducted in Alnarp. The pak choi and the living mulches were planted/sawn at the same time, the different covers were also applied at this time. The total experiment was divided into six different treatments (plus control) of which three were with covers and three were with living mulches. Once a week the number of leaves, the height and damages were read on ten of the plants from each parcel.

Syftet med denna studie var att undersöka skriftspråkslärande efter nybörjarstadiet, hos elever utan eget tal; med severe speech and physical impairment (SSPI) samt alternativ och kompletterande kommunikation (AKK). Frågeställningarna var följande:- Hur beskriver dessa elever själva sitt skriftspråkslärande?- Vilka fruktbara arbetssätt och miljöer för dessa elevers skriftspråkslärande finns dokumenterat i forskning?Metoderna innebar en livsberättelseintervju genom computer assisted personal interviewing (CAPI), samt systematiska litteraturstudier med en kvalitativ metasyntes som mål.Resultaten visar vikten av att dessa elever når en god läs- och skrivförmåga. Möjligheter öppnar sig för lärande och inte minst kommunikation över tids-, rums- och persongränser. Avgörande för elevers fortsatta skriftspråkslärande var förväntningar, kvalitet på undervisning samt stimulans inom den grundläggande emergent literacy-fasen.

The purpose of this article is to explore the technologies of government that are created within gender disorder assessments as an institution. I have done so by utilizing Norman Faircloughs discourse analysing instrument ?communicative action?, which focus on the social institution as relational.The material is strategically chosen by gathering texts from the Swedish state, the psychiatric clinics, NGO:s and by performing interviews with transsexual patients.When analysing the communication of the main agents, I have concluded that practices highly are a result of repeating text and speech inside the institution. The psychiatric assessments can also be seen as an illustration in changes in how citizens are governed in advanced liberal societies, where the role of the state has been gradually reduced in favour of other agents.I consider that the change illustrates an ?acting at a distance?-mentality where the patient is introduced to participate in the definition of the care in what I call ?negotiation as a technology?.

The purpose of this essay has been to investigate if the national test results, in the subject of Swedish B at upper secondary school, are affecting a student?s final grade in varied degree among different teachers. The purpose has also been to investigate if the assessment of these tests is equivalent among different teachers. This particular investigation showed that there are big differences between how teachers grade, in relation to achieved results on the national test. According to the Swedish National Agency for Education, the teacher should take all performance information available into consideration for each particular student.

The intention of this thesis is, from a basic statistical viewpoint, to capture the relationship between the price of electricity and a sample of factors influencing the price. The thesis also aims at investigating whether knowledge about the relationship is useful when investing on Nord Pool. Tested factors are temperature, import, price of emission rights as well as a number of hydrological factors. The investigated period stretches from year 2000 until week 32 year 2007. The relevance of each factor was also evaluated yearly as well as for shorter periods in order to get a more comprehensive view of the relationship.

The purpose of this thesis is to show how to use vulnerability testing to identify and search for security flaws in networks of computers. The goal is partly to give a casual description of different types of methods of vulnerability testing and partly to present the method and results from a vulnerability test. A document containing the results of the vulnerability test will be handed over and a solution to the found high risk vulnerabilities. The goal is also to carry out and present this work as a form of a scholarly work.The problem was to show how to perform vulnerability tests and identify vulnerabilities in the organization's network and systems. Programs would be run under controlled circumstances in a way that they did not burden the network.

Talapraxi är en talmotorikstörning som drabbar planeringen och programmeringen av talet, vilket visar sig som avvikelser i artikulation och prosodi. I dag finns inget svenskt test för utredning av talapraxi. Syftet med studien var därför att utforma ett testbatteri på svenska som är känsligt även för lindriga grader av talapraxi. Detta test pilotnormerades på 50 friska deltagare.  För att kunna studera hur kön, ålder och utbildningsnivå kan inverka på prestationen i testbatteriet, eftersträvades en jämn fördelning när det gäller dessa demografiska bakgrundsvariabler.Uppgifterna konstruerades baserat på tidigare forskning gällande de typiska perceptuella dragen vid talapraxi och på testuppgifter som tidigare har visat sig vara känsliga för talapraxi.Deltagarnas prestation varierade mellan testbatteriets olika uppgifter. På några uppgifter hade en stor andel av deltagarna alla rätt, medan andra uppgifter visade sig vara utmanande även för friska personer.

During the last years the need for real-time database services has increased due to the growing number of data-intensive applications needing to enforce real-time constraints. The COMponent-based Embedded real-Time database (COMET) is a real-time database developed to meet these demands. COMET is developed using the AspeCtual COmponent-based Real-time system Development (ACCORD) design method, and consists of a number of components and aspects, which can be composed into a number of different configurations depending on system demands, e.g., Quality of Service (QoS) management can be used in unpredictable environments. In embedded systems with requirementson high up-time it may not be possible to temporarily shut down the system for reconfiguration. Instead it is desirable to enable dynamic reconfiguration of the system, exchanging components during run-time.

Research shows that people with burnout experience a high degree of impairments in a range of cognitive functions including memory, attention and concentration. The overall aim of the present study is to investigate whether there is a correlation between subjective estimates of cognition and cognitive performance with objective tests in people with burnout with a focus on working memory and executive functions. Three specific questions were addressed; First, what cognitive problems are described and to what degree? Second, is the performance of executive and working memory tests related to self-reported cognitive problems? Third, are the self-reported cognitive problems related to measures of psychological distress? The study included 77 patients, 65 women and 12 men, with a mean age of 43.48 years. The results show that patients with burnout perceive themselves as having significantly impaired cognition in everyday life, which is clearly evident on the basis of the self-assessment forms PRMQ and CFQ.

Today there are many system development projects that break both budget and time plan. Often this depends on defects in the information systems that could have been prevented. The cost of test can in some cases be as high as 50 % of the projects total cost and it's at the same time an important part of development. Test as such has moved its focus from the software it self and its faults to a wider perspective on whole infrastructures of information systems where assure a good quality is important. Sogeti in the Netherlands have developed a test method called TMap (Test Management approach) that can be used for structured testing of information systems.

To support uniform and fair assessment of Swedish students? English language competences, mandatory National tests are provided both for secondary and upper secondary education. The current thesis may be seen as a contribution to the further development and validation of these tests, with regard to the likely introduction of computerized testing methods. The aim is to gain further knowledge from current research in the field, to study and elucidate international experiences of implementation, and to gather and analyze feedback from students and teachers. Based on my findings, some tentative conclusions will be drawn, and recommendations made concerning future developments.
