Påverkar tidighetstyp fiberhalten hos rödklöver?
The high feeding value of red clover makes it into an important species in Swedish agriculture. There are three different maturity types grown in Sweden, early, medium late and late. The time for heading, regrowth and winter hardiness is affected by the maturity type, but there can also be other factors that are affected by the maturity type, for instance fiber content. In a greenhouse experiment three red clover varieties of different maturity types were compared; early Titus, middle late SW Nancy and late SW Torun. The features compared were fiber content and differences in development rates.
Tre biblioteksbloggar för unga ? en innehållsanalys
The aim of this Master?s thesis is to examine three library weblogs to evaluate how they are used and what type of information the libraries publish in these specific weblogs.The following three questions are the basis of this study:? What is the content of the weblogs?? How is the weblog used as a tool by the libraries?? How is the interaction between the library and the readers of the weblogs presented regarding the comment function?The method that has been used in this study is content analysis and the code units have been created during the process. It is mainly a qualitative analysis but it does also contain quantitative elements. With the content analysis, 21 different themes where cut from the three weblogs. These themes where then put into the model of the local library profiles worked out by Marianne Andersson and Dorte Skot-Hansen.
Biblioteks- och informationsvetenskap som kunskapsområde En bibliometrisk studie.
The objective of the study is to map the cognitive structure of Library and Information Science, using a quantitative, bibliometric method. This empirical study shows how co-citation analysis combined with word-frequency analysis can be used to describe the subject content of the field. The research questions to be answered are: -Which clusters of authors can be identified? -How can these clusters be described in respect of their subject content, if the descriptors associated with the authors in the clusters are counted? The results show that the cognitive structure of Library and Information Science can be described by 13 clusters of authors, where each cluster is representing a specific aspect of the subject- domain. For the description of the subject content of the clusters, descriptors DE of the LISA database have been used..
En formalisering av matematiken i svensk gymnasieundervisning
This study examines how formal mathematics can be taught in the Swedishsecondary school with its new curriculum for mathematics. The study examineswhat a teaching material in formal mathematics corresponding to the initialcontent of the course Mathematics 1c could look like, and whether formalmathematics can be taught to high school students.The survey was conducted with second year students from the science programme.The majority of these students studied the course Mathematics D.The students described themselves as not being motivated towards mathematics.The results show that the content of the curriculum can be presented withformal mathematics. This both in terms of requirements for content and studentsbeing able to comprehend this content. The curriculum also requires thatthis type of mathematics is introduced in the course Mathematics 1c.The results also show that students are open towards and want more formalmathematics in their ordinary education. They initially felt it was strangebecause they had never encountered this type of mathematics before, but somestudents found the formal mathematics to be easier than the mathematicsordinarily presented in class.The study finds no reason to postpone the meeting with the formal mathematicsto university level.
Geografiska informationssystem för studier av polyaromatiska kolväten (PAH) : undersökning av djupvariation i BO01-området, Västra hamnen, Malmö, samt utveckling av en matematisk formel för beräkning av PAH-koncentrationer från ett kontinuerligt utsläpp
At the end of August 1999, the local government council of Malmö city decided thatthe area known as Kvarteret Bilen would be made available for the European HousingExhibition 2001 (Bo01-mässan). Kvarteret Bilen extends over approximately 80hectars and includes the western parts of the Western Harbour area (Västra hamnen)of Malmö.Kvarteret Bilen as a whole, but especially the western sections of this area, the socalledBo01 section, has been the subject of heated discussions. This is mainly due tothe fact that the ground in question has proven to be contaminated to a certain extentby different chemical compounds. Investigations undertaken during 1998 showed sporadically high concentrations forespecially one chemical group: polycyclic aromatic hydrocarbons (PAH).The first part of the paper describes the use of a mathematical equation (Fetter 1994)to calculate the concentration of PAH from a continuous discharge at a given time byemploying Geographical Information System (GIS). Even the constraints of theequation are discussed, as well as the consequences that follow as a result of usingGIS.The second part of the paper focuses on the connections between the content ofcarcinogenic PAH in Kvarteret Bilen and the ground water level and type of fillingmaterial.

The aspect of which geographical regions, covered by the liberal newspaper Gefle Dagblad, show a tendency that Gefle Dagblad concentrate their news coverage to the main region, the municipal of Gävle..
Något om misstag inom avtalsrätten : särskilt om gränsdragningen mellan förklaringsmisstag och motivvillfarelse
According to Swedish contract law, a mistake in contract can be categorized as either an error concerning the content of the agreement or an error in motive. An error concerning the content of the agreement could be described as a divergence between a party?s intent and his declaration, while an error in motive is a mistake about the reasons why a party would like to agree to the contract. The borderline between these two types of mistakes is based on Savigny?s theories on echt (error in motive) and unecht (error in content) mistakes.
Lärsituationens komplexitet för elever som upplever svårigheter i matematik : Rutiga Familjen i en ny lärmiljö
The Squares Family is a game developed as a learning aid in mathematics. With its graphical representation of the decimal system, the four basic arithmetic operations and positive and negative numbers together with a learning agent as pedagogical approach, the game?s primary purpose is to motivate students in their learning of mathematics. Although the game is strictly based on mathematical rules it attempts to encourage students to play and work with math without experiencing it as mathematics as this is initially not obvious. The game being internationally tested on normal performing students, this project introduced the game to six Swedish students who experience low motivation for and/or difficulties in mathematics.
Milk yield and composition in Swedish landrace goats (Capra hircus) kept together with their kids in two different systems
Swedish goats are mainly held for cheese production and therefore, both milk quality and composition are of great importance for dairymen. Today, only few data exists on milk composition from Swedish dairy goats and the casein content is still unknown. One way to reduce the work load for goat farmers and increase animal welfare can be to keep goats and kids together for longer periods. The aims of this study were to investigate how milk yield and composition were affected when kids suckled their dams during 8 weeks, and to measure the casein content on farm level by a mid-infrared spectroscopy method, previously calibrated for goat milk. Lactating goats were kept in two different MIX- systems where the dams are both suckled and milked.

It also shows if the coverage is concentrated to for example any special sports, clubs, people or topics.This study uses a quantitative content analysis and the result is based on texts from 28 systematically selected days during one year. In total, the study includes 906 texts.The result of this study shows that the sports content of TT Nyhetsbyrån?s news feed is mainly concentrated to two sports, football/soccer and ice hockey.
Att bryta tystnaden: kommunikation i matematikklassrummet
The purpose of this study is to investigate how teachers approach communication in their
mathematics instruction. The communication involves concepts such as teachers'
mathematical language, incorrect answers, and various interaction patterns. In line with this,
the study also examines how these types of communication may affect students in the
classroom. Furthermore, observations and interviews were conducted with five different
teachers in Sweden using an observation scheme and an interview guide. The results reveal
that four out of the five teachers use both child-directed and adult-directed language when
addressing students at different levels of mathematical understanding.
The Communicating Home - Definition, Evaluation and Business Opportunities for TeliaSonera in a 3-5 years perspective
The communicating home concept has been defined byidentifying the dominating communication technologiesto/from and in the homes, the most important customerbehavior and user needs, the dominating products and thedominating actors of the industry.The evaluation of the communicating home industry has beenperformed with a five forces framework analysis and theoriesregarding value migration and value structures of industries. Ithas been concluded that actors of communication technologies,goods and access services will compete fiercely. The barriersof entry will however be high. When it comes to contentservices the situation is completely different. These actors will,to the largest extent, meet lower competition and low barriersof entry.
Vad ?r en funktion?
The concept of function represents a major part of mathematics and becomes more significant
in school during high school. Throughout history, it has been a difficult concept to define and
may create challenges for contemporary students. This literature study aims to identify students'
difficulties with the concept of function, as well as to account for how the definition of a
function has evolved historically. The literature study has been conducted through database
searches in ERIC, Education Research Complete and MathSciNet via EBSCOhost, as well as
through chain searching. The study results in identifying that students' difficulties with the
concept of function primarily include the graphical and algebraic forms of representation.
Kvalitetsredovisning och undervisning i matematik
The aim with this master thesis is to analyze a scientific material concerning the context between learning and child/student development, and factors which controls process of learning, to create an image with quality account and teaching in mathematics, which then can raise the mathematical knowledge among students.The phenomena which stand in focus for the investigation is: why there is a negative tendency for development of knowledge in mathematics, among the Swedish students that TIMSSs investigations showed in intercultural comparison within the years 1993, 1999, 2003 and 2007.The method is the ethnographical method, which is based on: analyzing scientific theories about learning child/student development, factors which controls process of learning, and factors which controls process of learning the most and qualitative empiric investigation with qualitatively analyzes the questionnaires, which is about factors which are controlling the process of learning and factors which are controlling the process of learning the most.Result of the theoretical and empiric analyzes shows that factors as school environment, attitude for subjects and teaching, controls and influence the learning. To end a unenthusiastic tendency as a negative development of mathematical knowledge among students that is shown in TIMSS investigation and to elevate the students' performance in mathematics, an elevated qualitative account and teaching in mathematics, by the factors named. Safe school environments as the intercultural meeting place, the teachers influence part to the students' subjects' attitude in mathematics and goal related grading criteria in teaching, is all required for e qualitative teaching in mathematics..
Mediekonsumtion som verktyg för ungdomars identitetsbildning : En kvalitativ studie om hur ungdomar använder medier för att påverka andras bild av deras identitet
The purpose of this study was to investigate to what extent young adults use media to create the image of themselves. The questions we wanted to answer was as follows: what does the media use of young adults look like compared to their attitudes towards media content; what awareness do they have of other young adults attitudes concerning media content; and finally, how do these attitudes affect their own media use?Media consumption is a great part of the daily lives of young adults living in Sweden: the national average media consumption is seven hours a day, for 15-24 year olds. This provides a new way for young adults to express their identity - by showing their use of different media content, they can change other's perception of themselves.The method we used in our study was a combination between a quantitative and a qualitative method. We first made a survey in three classes with senior year high school-students, in a Swedish school.
