Möjligheter att förutsäga kvävegödslingsbehov i höstvete med Yara N-tester

The Yara N-Tester is a handheld chlorophyll meter which can be used in several different crops as an aid to determine if there is a need of complementary fertilization with nitrogen (N) or not. If the crop requires more N the N-Tester will recommend an amount in kg per ha. The possibility to assess the need of N depends on the strong relation that exists between chlorophyll- and N-concentration in the leaves of plants. In the multiannual trial series ?Nitrogen to winter wheat at different soil conditions? measurements with the N-Tester was carried out at flag leaf emergence (GS 37). In this work the result of measurements, the NTesters ability to estimate the need of N in winter wheat, will be presented for the years 2008-2011.

Analys av mellanspänningsnätet i centrala delar av Västerås stad

The dependency of continuous electricity supply is high in the Swedish society today, at the same time no one is willing to pay for a too costly or over dimensioned power distribution system. The owners of the distribution systems are the ones responsible for this balance act of maintaining a high quality of electricity delivery to customers at a reasonable cost.In this master thesis a limited part of the primary distribution system (10 kV), owned by Mälarenergi Elnät AB and located in the city centre of Västerås, was chosen for a deeper analysis of its reliability. Its ability to handle outages of system components (N-1 and N-2 contingency analysis) was investigated to find out potential weak spots and parts of the grid that showed signs of being overdimensioned.The results of the performed simulations showed that in 74 % of the studied N-1 contingencies cases, consisting of outages of a bus bar in a distribution substation, the system could handle this without causing outages in other parts of the grid. For the N-2 contingencies 61 % passed the test. It was also found that one of the two included high voltage substations could alone supply the investigated part of the grid.

?Det finns ju inte med i boken, ska jag kunna det ändå?!? : en studie om elevers övertro till läroboken som angivare av kunskapsmål samt vilken misstro detta skapar till all undervisning som går utanför dess ramar

The purpose of this study has been to get a deeper insight into how students reason about the textbook and teaching that goes beyond its content. This in order for the teacher to be able to consider and respond to these important attitudes already at the planning stages of such teaching situations. This approach will aid to help students overcome the distrust of things that are not in the textbook.The study shows that students have an attitude of overconfidence to the textbook's reliability. It is considered to be controlled in its content as well as being a reference on the extent of the knowledge content.The general approach to teaching that deviates from textbook structure is that it is welcomed as an interesting feature. However, a questioning attitude soon appears about whether the element will be included in any requirements for knowledge or tests.The following important conclusions can be drawn after this study was carried out:Very clearly communicate the purpose of all education that deviate from the textbook.Inform students about the textbook's deficiencies and the need for supplementing.Accept and respond to students' focus in that grades are the main driving force for the acquisition of knowledge in high school..

En beskrivande studie av Svenska Onlinebaserade tjänsteföretags internationaliseringsgrad.

IKEA is probably one of the most well known Swedish companies in the world. During thepast decades millions of people all across the globe have decorated their homes according tothe style of IKEA. But just exactly how big and influential are they? Many, if not to say all,municipalities in Sweden wants IKEA to establish and build their famous stores in one oftheir towns. But at what cost? When deciding on a municipality to establish in, IKEAnormally tends to have an advantage when it comes to controlling the conditions and terms ofthe establishment.To undertake this dissertation I use a theory based upon the inter-organizational theoriescalled resource dependency theory.

"Land skall med lag byggas" - en studie av policyprocessen kring ett lagförslag -

This thesis concerns the policy process of a proposed bill. The specific bill constitute a new penal law which is supposed to replace the old penal law from 1974.The questions asked considers what in the foregoing policy process that has proceeded, affected and also characterizes the proposed bill. In order to be able to produce a deep and reliable analysis to this question I use two different theories.The first theory being used consists of John W. Kingdons theory of ?multiple streams? which I use to answer the specific question ?what can be recognized to have proceeded and characterize the policy process that the penal law bill involve??.The second theory consists of Peter Santesson-Wilsons development of symbolic policy theories which is given a concrete form in the ?taxonomy of symbolic policy? which he presents.

Civil-militär samverkan i det moderna Totalförsvaret

I regeringens budgetproposition för 2011, erhöll Försvarsmakten uppgiften att införa fyra Militärregioner i Sverige med underliggande regionala staber. ?Regeringen bedömer att skapandet av de regionala staberna innebär att Försvarsmaktens förmåga att samverka med och lämna stöd till andra myndigheter förbättras.? (PROP 2010/11:1 s.33).Syftet med den här studien är att studera hur personer med nyckelpositioner inom de båda myndigheterna (Länsstyrelse och Försvarsmakten) tänker kring införandet av Militärregioner och dess förutsättningar för utveckling av samverkan mellan det civila och militära samhället.Resultatet påvisar att informanterna är relativt överens om att samverkan ska utvecklas och hur det bör ske med ett fokus på gemensam planläggning, utbildning, övningar samt nätverksskapande och utarbetande av gemensamma mål innan något händer. Målsättningen är att klara av att hantera oförutsedda händelser som olyckor och naturkatastrofer när de väl kommer. Informanterna anser även att närheten, i såväl tid som rum, är avgörande för planläggning och den slutliga insatsens resultat..

Barns flerspråkighetsutveckling : Hur föräldrar till flerspråkiga barn tänker kring flerspråkighet i hem och förskola samt hur deras tankar och upplevelser tas tillvara på förskolan

The purpose of our study is to interpret and understand the experiences that parents to multilingual children have towards multilingualism in pre-school. We are also interested in finding out what these parents think about their children?s development in multilingualism both in pre-school and at home. Our study is based on qualitative interviews. We interviewed nine families that have multilingual children in pre-school.  The data we collected from our interviews has been analyzed using socio-cultural and inter-cultural theories along with previous research. The result of our study showed that parents to multilingual children have both positive and negative opinions about the multilingual concept. Most of our informants had positive opinions about multilingualism in general.

Hållbarhetsredovisning i svenska företag: - utveckling, trender och drivkrafter

This study aims to investigate development and reasons behind sustainability reporting in large Swedish companies. By examining 15 companies? environmental and sustainability reports between the years 2000 and 2008, data was collected on matters such as frequency, scope and design. Identified trends were to a large extent in line with previous studies on international development; sustainability reporting is growing in several aspects. The authors have found one major reason for this development to be increasing requirements and expectations from stakeholders and a need for companies to legitimize their actions.

Dominansprofiler - en väg till din inlärningsstil?

In this study the reliability of dominance profiles as a method of establishing a person's learning style was tested. Eight students at Malmö Academy of Music tried three different ways to learn a short melody at the piano. In this way, their preferred way of learning things (either visual, auditive or kinestetic) was established. Five of the students did best when they used a visual cue to learn a melody, and the remaining three did best when auditive cues were used. All but one of the students had the worst result in the kinestetic trial.

Lärarens ledarroll : En kvalitativ studie om lärarens ledarskap i förskolan och i skolans tidigare år

Syftet med denna studie var att undersöka uppfattningar som olika lärare har om ledarskap. Ledarstilar är en del av begreppet ledarskap och används också i arbetet. Studien omfattas av två förskollärare och två lärare för skolans tidigare år och har en kvalitativ ansats som är en småskalig studie bestående av observationer och inter­vjuer för att som forskare kunna bilda sig en förståelse om det undersökta fenomenet. I resultatet framkommer det att samtliga lärare har olika uppfattningar kring sitt ledarskap i praktiken och det synliggörs under många av observationerna att lärarna använder olika ledarstilar vid ett och samma tillfälle. Det visar sig en skillnad mellan de olika lärarnas sätt att leda sin undervisning och det synliggörs att förskollärarna ser till barnens behov i utformandet av verksamheten och i skolan visar det sig genom att lärarna har mer fokus på uppgiften.

Beslutstödssystem for investeringar och underhåll i eldistributionssystem

I detta examensarbete har en tillförlitlighetsmetod tagits fram som väger samman kostnadspåverkande faktorer för investeringar och underhåll i eldistributionssystem med kostnader förknippade med avbrott. Syftet med metoden är att möjliggöra för nätplanerare och projektörer att jämföra olika investeringsalternativ för att kunna kostnadseffektivisera investeringarna i eldistributionssystem. Med tillförlitlighetsanalys kan den förväntade avbrottstiden i systemets uttagspunkter beräknas. Kopplas en kostnad till den förväntade avbrottstiden i uttagspunkterna kan den förväntade avbrottskostnaden för distributionssystemet beräknas. Syftet med simuleringarna har varit att undersöka om det går att minimera den totala kostnaden, investeringskostnader samt förväntade avbrottskostnad, genom slumpvisa investeringar i systemets ledningssektioner. Simuleringarna har genomförts på ett fiktivt mindre system.

Säkerhetsanalys av brandbekämpning i kritiska utrymmen på Forsmark 1

In order to maintain a high safety level at a nuclear power plant it is important not only to measure the reliability of the components and systems of the plant, but also to investigate how the plant responds to human actions. One of the most hazardous situations in managing a power plant is fire occurring in critical areas. This study concerns the prospect of the local fire brigade to suppress a fire that has started in one of the most critical rooms for maintaining high reactor safety. The model created gives an indication on the possibilities of succeeding in suppressing a fire. In order to get a more reliable fire fighting the following advice are given:- Let the fire brigade go rounds in the plant together with the personnel, during which recommended fire suppressing methods are determined to avoid long preparation time in an actual situation.- Prepare rooms with two subsystems to make them partly with no voltage.- Give the fire brigade better feedback from actual events on nuclear power plants.- Education and training in suppressing fires in electrical equipment.The probabilistic safety assessment strives to be as realistic as possible.

TaqMan® Sample-to-SNP Kit? : evaluation of kit for low-cost and fast preparing of DNA-samples before genotype analysis

 Genotyping can be used to link genetic variation among individuals to certain diseases or conditions. Some known disorders and states that are dependent on single nucleotide polymorphism (SNPs) are lactose intolerance, venous thrombosis, hereditary hemochromatosis and the difference in sensibility among people to metabolise drugs.In this project a new kit, TaqManÒ Sample-to-SNP KitÔ for extraction of DNA and preparation of the extract for genotyping with real-time PCR and allelic discrimination, was evaluated. QIAamp® DNA Blood Biorobot® MDx Kit was used as the reference method.The purpose of the comparison was to find a method that makes DNA extraction from blood samples cheaper and faster, but with the same reliability as the reference procedure.The results of the evaluation showed a complete agreement of the genotype results between the methods tested, which means that the new method was as reliable as the reference method. The costs of reagents and material would be reduced with 52% if the new method is adopted, that alone would result in a cost reduction of 144 000SEK a year with a sample volume of 650 samples/month. The time for DNA extraction would also be reduced with the new procedure. .
