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.
Genetiska och epigenetiska samband mellan näringsförsörjning och fertilitet hos mjölkkor
The dairy cow?s ability to resume estrus after calving and to conceive is affected by their metabolic status after calving. For high yielding cows there is a high risk that the feed intake will not be sufficient to cope with the increased energy demands after calving, and the cow will end up in a state of negative energy balance. Energy balance can be measured in various ways, for example by body condition score or by plasma concentration of several metabolic hormones and metabolites. After calving, endocrine pathways stimulate tissue mobilization; insulin signaling is blocked, the concentration of insulin-like growth factor-1(IGF-1) and leptin decreases, and the concentration of growth hormone (GH) increases.
Språksvårigheter: en definitionsfråga : En diskursiv studie om förskolans förhållningssätt, värderingar och synsätt i förhållande till barn med språksvårigheter
After having worked within the preschool and it?s system for a number of years, we have often reflected over the fact that many educators tend to look at children with language difficulties in several different ways, and many of them being conflicting. Something that might contribute to this problem is the fact that the term itself, language difficulties, is defined differently between individuals, who in turn affects the way educators and preschools deal with the problem.The aim of this study is to create an understanding of the problems related to language difficulties, and how it is being dealt with within the preschool environment. To achieve this we have chosen to work within a qualitative research approach, alongside a discourse analysis. The selection of informants we have chosen consists of ten, qualified educators.
Comparison between anesthesia with sufentanil-midazolam and sevoflurane in medetomidine premedicated rabbits undergoing ovariohysterectomy
Rabbits carry a high risk of anesthesia related death. This study was part of a project to develop a form of total intravenous anesthesia (TIVA) with minimal effects on cardiac, respiratory and metabolic parameters. In the study, TIVA with sufentanil and midazolam (group TIVA, n=9) was compared with inhalation anesthesia with sevoflurane (group SEVO, n=9) in female rabbits undergoing surgery (ovariehysterectomi). All rabbits were pre-medicated with medetomidin and carprofen before anesthesia induction. Anesthesia was induced with TIVA (2.3 ?g/ ml sufentanil, 0.45 mg/ ml midazolam) at a rate of 4 ml/ kg/ h and the mean induction dose was 0.4 ?g/ kg of sufentanil and 0.1mg/ kg of midazolam.
Effekt av spädningsvätska på spermiemembranintegritet analyserad med NucleoCounter SP-100 :
This study is a part of a larger project where the aim has been to evaluate different methods to assure the quality in stallion semen, due to the fact that some stallions in horse breeding have poor semen quality. The increased use of transport semen requires new methods to ensure good semen quality.
In this part of the project the viability and concentration in fresh and cooled semen was examined with NucleoCounter SP-100. A comparison between two different commercially available semen extenders, Kenney?s and INRA 96, was made.
Lärandemiljöns betydelse för barn i koncentrationssvårigheter The importance of the learning environment for children in concentration difficulties
Syftet med arbetet är att beskriva ett antal pedagogers uppfattningar om lärandemiljöns betydelse för barn i koncentrationssvårigheter samt vilket stöd de önskar av specialpedagogen. Undersökningen bygger på tio intervjuer med pedagoger från två kommuner. I detta arbete vill vi ge en bild av hur dessa pedagoger tänker kring lärandemiljöns betydelse för barn i koncentrationssvårigheter, hur de arbetar samt vilket specialpedagogiskt stöd de anser sig behöva. För att få en teoretisk grund redogör vi först för den litteratur vi utgått ifrån samt den teori som vi tror är aktuell för vårt arbete.
Sammanfattningsvis kan vi konstatera att pedagoger är medvetna om att lärandemiljöns utformning är av stor betydelse för barn i koncentrationssvårigheter. Samtliga pedagoger upplever att de stora barngrupperna påverkar problematiken för barn i koncentrationssvårigheter.
Kvinnor och deras karriäravancemang på managementkonsultföretag - en fallstudie om varför det är svårare för kvinnor att avancera på managementkonsultföretag
The purpose of the thesis is to examine why women face greater difficulties than men in the management consulting industry when advancing as well as to identify potential success factors that enable women to overcome the existing difficulties. In order to fulfil the purpose, a theoretical framework including gender and organisational theory has been applied to a qualitative case study of two Swedish management consulting firms. A number of difficulties have been identified related to women's career advancement, which are the following: the male leader and the stereotypical male leadership, firms having higher expectations on women's performance, women's reluctance to self-promotion and to play "the organizational game", women's preference of social networks, men's tendency to promote other men, and the choice and conflict between a career and family life. The identified success factors that enable women to overcome these difficulties are: adapting the male leadership style, having an extrovert behaviour, becoming more active in professional networks, promoting one self, actively seeking to gain more attention, and prioritising one's career. These success factors can be summarised as women adapting a more male-like behaviour.
Barn som far illa : En kvalitativ studie om hur förskollärare resonerar kring sin roll i arbetet med barn som far illa.
The aim of this study is to contribute knowledge about how preschool teachers reason around their role in the work with children being maltreated. The study has been based on the following questions: How do the preschool teachers identify children being maltreated ? How do the preschool teachers act after they have identified a child thats being maltreated? What difficulties experienced preschool teachers based on their professional roles related to child maltreatment? The method used in the study is a focus group interview, which is a kind of informal group discussion. The result shows that there are difficulties in the preschool regarding the work with children being maltreated. Some of the difficulties that the preschool teachers raised was the contact with the guardians, society?s negative perception of the social services, that all the notifications must go through the pre-school manager and that they don?t have so much experience of notifications. .
Mixture and single-compound toxicity using Daphnia magna : comparisons with estimates of concentration addition and independent action
Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.

Glycerol till mjölkkor : effekter på våmmetabolismen
Glycerol is essential for the lipid metabolism of both plants and animals. Glycerol is formed in the rumen by hydrolysis of lipids from the feed. Glycerol is also a by-product from the production of biodiesel from rapeseed oil and other fat sources. Glycerol might be used as a dietary glucose precursor for dairy cows in similar ways as propylene glycol. Due to increased production of biodiesel more glycerol has been available to a lower price.
Phycoremediation of pesticides using microalgae
Every year, pesticides are found in surface and ground waters in Sweden. Fungicides are in common usage and applied in high amounts against potato late blight. The present thesis examined the possible removal of four fungicides (metalaxyl, cyprodinil, propamocarb and
mandipropamid) from water using the microalgae Chlorella vulgaris. Microorganisms are capable of decomposing a range of organic pollutants and the main focus in previously published studies has been on bacteria and fungi. Microalgae are mostly studied due to their high capacity
in biosorbing heavy metals.
Lärare på distans! : Lärares upplevelser av möjligheter och svårigheter med distansundervisning
The purpose of this essay is to show the opportunities and difficulties of teaching within distance education. I will show this from two different parts of the world. One being Sweden and the other Australia, both countries run a distance education program with similar reasons students whom travelling, some living hundreds of miles from any schools and some students with health and or social disadvantages. This study is based on the actual teacher?s accounts and experiences the opportunities and difficulties in teaching in distance.
Språkets betydelse för matematikinlärningen
Study aimed to see if the language has bearing on mathematics learning. The study used qualitative interviews of three first grade teachers and one special education teacher.The questions asked was:Do the teachers and specialist teacher, at the selected schools, think there is a connection between language difficulties and difficulties in mathematics and in case how is this connection.How does the teachers / specialist teacher make it easier for students to learn mathematics and swedish.The study was based on Vygotsky and Piaget teories. In previous research, it is primarily Malmer, Hoines, Lowing and Kilborn who´s been treated. Within the governing documents, it is mainly the compulsory school curriculum Lpo-94, and the curriculum for mathematics treated.I hope that the study has conclude that there is a connection between language and mathematics learning.I tried to emerged this through interviews with tree teachers and one special teatcher but i couldn´t. The teatchers couldn`t fint that it was the only reason to why the pupils hade difficulties in mathematics.But in the literature I found the relation between language- and mathematicdificulties..
