The aim of the study was to investigate if methane emission in a constructed wetland changed in a diurnal pattern correlating to temperature, humidity or light conditions. The gas measurements were carried out with a static chamber technique. The wetland (in Nykvarn outside of Linköping, Sweden) takes care of wastewater to reduce the nitrogen loads. Measurements were carried out at three different occasions in the summer of 1998 on two sites in the wetland. One site was close to the inflow, inhabited by Lemnaceae, and another site was located further downstream inhabited by the emergent macrophyte Typha latifolia.

Studiens syfte var att undersöka rektorers uppfattningar om skriftliga omdömen samt hur de tar ansvar för arbetet med dessa. Syftet var också att studera hur de omdömen som lärare skriver ser ut i praktiken avseende innehåll, för att se hur omdömena överensstämmer med rektorernas uppfattningar.I detta arbete har vår utgångspunkt varit de skrivningar i läroplanen (Lpo 94) och de allmänna råden (Skolverket, 2008) som uttrycker något om rektors ansvar samt elevers lärande- och kunskapsutveckling. För att få svar på våra frågor har vi intervjuat tio rektorer som tillsammans representerar grundskolans alla stadier samt studerat innehållet i 1245 skriftliga omdömen. Studien genomfördes i en mellanstor svensk kommun.Resultatet visar att rektorerna i huvudsak är positiva till skriftliga omdömen men att de är kritiska till det stöd de fått för implementering. Ett skäl till att rektorerna är positiva är de pedagogiska diskussioner som reformen medfört.

New high strength steels require improved cold rolling techniques. The aim of this degree project was to develop a new and money saving cold rolling technique to manufacture steel strip for saw blades. The work is based on earlier rolling experiments made with a high carbon steel grade at LuCoil Steel AB. The work also focused on the mill requirements to cold roll high strength steels. The results show that LuCoil?s existing cold rolling mill was actually designed for rolling low carbon steel.

In the school subject of the natural sciences it is imperative that the students are given opportunities to ?talk science?, since the dialogues that occur in the classroom have a significant importance for the students? abilities to engage in meaning-making in their learning process. Hence, the student and teacher interaction in the classroom and the feedback given there play a significant role in the students? learning process. The aim of this study is to contribute to the development of formative assessment tools that can mediate the students? meaning-making in natural sciences subjects in upper-secondary school.

Predatory pricing is one of the most frequently discussed topics in competition law and should be considered both from a legal and economic perspective. The concept of predatory pricing can bedescribed as a situation where a company is pricing at a level that, according to the assessment theories, is unreasonably low. The problems with this type of conduct arises when the low prices hinder competition. A company which uses predatory pricing will likely deter rivals entry to the market or drive the existing ones out of it. In the long run, the effects on competition will likely be higher prices which will hurt customers and consumers as well as competition.

AbstractThe purpose of this bachelor thesis is to describe the use of artificial insemination (AI) in sheep and discuss the possibilities for AI in Sweden. Male and female fertility, heat detection, semen handling and insemination techniques in sheep are described. Advantages and disadvantages of AI are discussed. In order to achieve genetic progress it is important with well planned and implemented breeding programs. The Swedish Sheep Recording Scheme and computer software from Elitlamm are the basis for sheep breeding in Sweden.

The purpose of this study is to analyse the significance of the national assessment in highschool education, including what the teachers express about the new instructions currently coming from the Swedish National Agency of Education, concerning a more central control of grading the national assessments. This study also covers the teachers individual responsibility when it comes to grading the national assessments. The purpose of the national assessment is to secure that grading and the education level in the country is equal. This is a qualitative study useing the method of a group discussion intervju (focusgroup intervju). Five highschool teachers took part in the discussion with questions that had been decided beforehand.

The aim of this project was to look into ten small sewer systems in the municipality of Laholm, in Sweden, in order to work out common assessment grounds for them. The sizes of the systems for purification of wastewater were within the range of 25 to 2000 population equivalents. Our method was to study literature, the laws and regulations applicable and the files at the municipality. The conclusion is that every sewer system is different and every situation is unique. We concluded that based on laws and assessment grounds sewer systems equal in size and pollution load ought to have similar demands attached to them.

Changes in swallowing function are common in elderly and chronically ill individuals. Therefore it is important to be aware of these changes and their prevalence. The aim of this study was to assess the prevalence of dysphagia in nursing homes in the municipality of Linköping, and to correlate dysphagia with variables that can be a cause or a consequence of dysphagia. These variables were gender, age, MMT-result, dentition, weight loss, medical diagnose or number of medications. The intention was also to examine the additional information regarding dysphagia supplied by pulse oximetry.Sixty nursing home residents aged 74-101 years were chosen to participate in the study.

Syftet med denna undersökning är att undersöka vad kvalitativ bedömning av kunskaper och färdigheter innebär för lärare samt att hitta variationer i dessa uppfattningar. För att nå vårt syfte har vi använt intervju som metod med en fenomenografisk ansats. Vi har intervjuat tre lärare i en skola som undervisar i år 8 och år 9. Vi har utgått från aktuell forskning. Utifrån denna forskning har vi format en analysmodell som vi använder som en teoretisk ansats i slutresultatet.

Safety and risk management currently have a starting point based on the negative outcome of safety, thus the lack of safety. The starting point for the thesis is to find a way to measure the positive outcome of safety through ergonomic aspects regarding chemical plants that are covered of the Seveso II Directive.Through a literature study of safety and ergonomics fourteen key aspects of safety were found. Safety Performance Indicators (SPI's) are used to assess the fourteen identified proactive indicators of safety. An analysis in three steps - called risk status assessment - is design to give an SPI its value. A pilot study of the risk status assessment was performed at the ethanol producer Lantmännen Agroetanol in Norrköping, Sweden..

The purpose of this essay is to describe and analyse the dilemmas within assessments to establish the parenting ability of mentally handicapped parents, and furthermore to see how these assessments are carried out.To achieve this purpose we have interviewed eight professionals from three different professions who comes into contact with mentally handicapped parents throughout these assessments. These professions we have interviewed people from, are employees from social services, employees from assessment homes and lawyers.We have summarized the results of our interviews into three main themes. The first is focusing on which method/model employees from social services and assessment homes use to help establish the parenting ability of mentally handicapped parents. The second theme describes different dilemmas that can arise in these assessments and the last theme describes the knowledge that people we interviewed have regarding mentally handicapped parents.Professions which carry out assessments of mentally handicapped parents often come across a variety of different dilemmas, one of the clearest is how to enable these parents to understand the necessity behind the assessment and to give them an understanding of what kind of help and support they need in order to give their children a "good enough" childhood..

One important issue faced by companies is to secure their information and resources from intrusions. For accessing a resource almost every system uses the approach of assigning a unique username and a password to all legitimate users. This approach has a major drawback. If an intruder gets the above information then he can become a big threat for the company and its resources. To strengthen the computer security there are several biometric methods for identity verification which are based on the human body?s unique characteristics and behavior including fingerprints, face recognition, retina scan and signatures.

The aim of the study is to show how a selected part of the European Language Portfolio, ELP, can support the assessment process for teachers. All the checklists at level A1 and My Language Goals from the Language Biography, a part of the ELP, are implemented and communicated in teaching in a 4th grade class of students. Two teachers are interviewed and both of their classes are compared in the study. One group worked for two weeks with the selected part of the Language Portfolio and the second group followed the regular curriculum for the same period of time. The teachers are interviewed before and after the ELP through support of mind maps.Results show that by using checklists at level A1 and My Language Goals students become aware of their own learning process.

Sedan 1990-talet har Sverige ett kunskaps- och målrelaterat bedömningssystem i skolan där eleverna blir bedömda och betygsatta utifrån ämnesplan och kunskapskrav. I samband med den nya skolreformen 2011 reviderades innehållet i dessa styrdokument. Studiens syfte är att belysa hur engelsklärare resonerar i sitt val av bedömningsformer för underlag vid bedömning och betygssättning i förhållande till ämnesplan och kunskapskrav i Gy11, samt att undersöka om det finns skillnader i lärarnas bedömningsarbete i jämförelse med Lpf94. Undersökningen har genomförts vid en gymnasieskola där kvalitativa intervjuer har hållits med fem engelsklärare som undervisar i kursen Engelska 5. Studien visar att bedömning sker kontinuerligt av lärarna, men att de har olika sätt att bedöma, dokumentera och använda sig av bedömning i lärandet.
