Majsensilage i Sverige
Maize for silage has been used as fodder in different parts of the world for a long time and has recently become more common also in Sweden. Our cold climate has been a problem as maize is very sensitive to low temperatures and frost. With new varieties and better techniques for cultivation it is now possible to grow maize in the southern and middle parts of Sweden. As for the north of Sweden the length of the cultivation season is a limiting factor as there are too few days with temperatures of over +10 ºC. Maize is well suited for silage making but oxygen-free conditions are required.
Testikelmått och daglig spermieproduktion hos svenska halvblodshingstar :
Testicular measurements and daily sperm output (DSO) are important factors affecting reproductive capacity of stallions. In the present study testicular measurements of 10 Swedish half-blood stallions were determined (height, length, width and volume). Ejaculates were collected from each stallion once daily for 10 days to evaluate some important seminal characteristics: gel-free ejaculate volume, sperm concentration, percent progressively motile spermatozoa and total number of spermatozoa (TSN). The gel-free ejaculate volume was measured with a graduated cylinder, the sperm concentration was counted in a Bürker chamber, the sperm motility was estimated in a phase-contrast microscope and TSN was determined by multiplying the gel-free seminal volume by the sperm concentration. Testicular measurements were as follows (left and right testis): height 7,5 cm and 7,8 cm, length 10,6 cm and 10,8 cm, width 6,5 cm and 6,6 cm, volume 278,2 cm3 and 293,8 cm3, scrotal width 12,3 cm and total testicular volume 572,0 cm3 .
Lika möjligheter till ett livslångt lärande?: en studie av svensklärares förhållningssätt till användningen av skönlitteratur och skolbibliotek
The purpose of this study is to examine the view of Swedish language teachers on the role of fiction and of school libraries within the compulsory school?s teaching of Swedish of form 6-9. The questions to be answered are:? What part do Swedish language teachers (hereafter called teachers) think fiction is playing regarding the pupils inclination to read and reading promotion?? What is the attitude of teachers regarding the function of fiction in the Swedish subject?? What do teachers consider being the role of the school library in education, and can this be related to the local school library resources?To answer the questions a questionnaire was sent out to thirty-five teachers. Four qualitative interviews were also carried out among the fourteen teachers that answered the questionnaire.
Aktiv ventilstyrning
To achieve an optimal combustion, an even air/fuel ratio in the combustion chamber is required. An optimal combustion leads to reduced amount of emissions due to a more complete combustion, which is an important matter because of the sharpened environmental laws. This can be attained, among other things, by applying entirely variable cam times. To optimize the engines efficiency and its emissions at all workloads and speeds, an active valve control can be applied. This means that the intake and exhaust-valves can be opened and closed at any time, independent of the crankshaft position.
Socialt Kapital och de Svenska Hjälpkassorna : En historisk undersökning om föreningar, socialt kapital och ekonomisk utveckling
The purpose of this research is to examine some historical aspects of Robert Putnam?s thesisabout voluntary associations and social capital. According to a micro perspective theory ofsocial capital the trust and reciprocity required and created by associations is important toexplain the disparity between institutional performance and socioeconomic development ofsocieties. The social patterns governing this therefore set a precedent for the future. Using themutual sickness benefit societies in Sweden as variable for voluntary associations around1884, the essay discusses the possible links between social capital, associations and long termeconomic development.
Lindehults handelstr?dg?rd: en fallstudie med fokus p? j?rnv?gens nytta f?r en ?kad marknad
This case study's aim was to strengthen the state of knowledge about how horticultural
companies in Sweden used railway transports between 1900s and the 1950s. Economic
theories and a micro-historical perspective have been used to analyze the collected
source material, and to describe Lindehult's market garden. The investigation is based
on document analyzes, qualitative interviews, archive studies and literature studies to
evaluate the sources' information through a source pluralistic method. The work has
been based on historical source material in the form of payment vouchers, giving an
insight into how the company's products were transported by rail across Sweden. Sture
Hjalmarsson's diary and interviews have described the case and events that affected the
company internally.
Kommunalt självstyre i Enköping och Uppsala 1862 - 1887
Sweden was transformed to a democratic industrial society in the late 19th century. Political influence had been bound to the four estates, nobles, clergy, burghers and farmers. The reforms of the 1860s moved Sweden towards political democracy with universal suffrage. At the national level a two-chamber parliament was established in 1866. Political power should now be a function of economic status.
Socialtjänstens stöd till familjehem ur utvecklingsekologiskt perspektiv - Fallet Linnéa -
The aim of this essay was to investigate how social workers, within chosen Social services districts in the northwest of Skåne, work with children placed in foster care. Our purpose was to investigate the interaction between the child and the foster home from the perspective of the Ecology of Human Development. Our questions were:* How do the social worker prepare the child and the foster home before a placement?* What kind of support is offered to the foster home with the purpose of supporting the child?* How do the social worker make the childs contact with the biological parents easier?* To what degree does the social worker work on strengthening the child's network?* Which factors do the social worker decide the allocation of support?* What do the social worker think affects the work with the foster home from a society level?To answer our question we have interviewed nine social workers. We found that the social workers were generally good at perceiving how the micro- and meso-systems, and to a certain extent the exo-system, influenced the foster child.
Vilken läsförståelse är det som bedöms?
Denna examensuppsats skrevs under utbildningen på speciallärarprogrammet på Malmö Högskola under våren 2015. Det är en kvalitativ studie som utgår från det sociokulturella perspektivet där talet är tankens redskap. Jag har genom fokusgrupper och lärarnas reflektioner i form av dokument samlat in min empiri. Det insamlade materialet har jag analyserat utifrån Kintsch och Rawsons modell för läsförståelseprocessen och bedömningens olika former. Mitt resultat visar på att lärarna, när de bedömer elever, bedömer hur väl eleverna kan genomföra olika aktiviteter kopplade till läsförståelse.
Undersökning av förlustförändringar i lågspänningsnät uppkomna av mikroproduktion med solceller
Detta examensarbete har utförts på Vattenfall Eldistribution AB i Trollhättan och syftar till att beräkna förlustförändringarna i lågspänningsnätet då mikroproduktion i form av solceller ansluts.Genom att ansluta mikroproduktion i lågspänningsnätet kan nätets energiförluster reduceras. Denna reducering samt den energi som inte behöver överföras från överliggande nät anses vara den nätnytta solceller ger upphov till.Samtliga elproducenter som är anslutna till elnätet har rätt till ersättning för nätnytta uppkommen av produktionen. Ersättningen skall baseras på inmatad energi samt vid vilken tidpunkt inmatningen sker. För mikroproducenter är det svårt att motivera att i varje enskilt fall beräkna nätnyttan, varför ett generellt schablonvärde beräknats för Vattenfalls lågspänningsnät. Beräkningen har utförts utifrån uppmätta sol- och lastdata på sex olika lågspänningsnät vilka tillsammans anses representera ett generellt nät.
Portfolio som arbetsverktyg i förskola och skola - barns beskrivningar av sin portfolio
The study sheds light on pupils individual plans of development and portfolios from the perspective of children. It has an ethnographic standpoint. It was carried out on children and pupils in pre-school, pre-school class and third grade. By further investigating how children and pupils use their individual development plans and portfolios, in which settings and to whom they communicate them, this study is able to grasp the discourse that is created around the instrument itself. This study is also interested in and aims to find the theoretical frame, in essence, which envelops both the construction of childhood and children?s own activities within the limitations and opportunities that this structure offers.
En berg- och dalbana av genusstrategier : En studie om den normativa genusbildens konsekvenser för kvinnor med erfarenhet av narkotikamissbruk.
A qualitative interview study how the normative gender images affects on women, their roles and positions in a drug abuse. The purpose of this study aims to shed a light at the consequences that the normative gender scenario inflicts on women with drug abuse and how these prejudices affects these women. Based on interviews with four different women who all lived with a drug abuse we have problematized how the gender system and the normative gender images affected them. We have used gender perspectives and social constructivism theories while analyzing the empirical basis. More specifically we use the theories of Butler about how gender constructs through performative actions and Hirdmans theories of the gender system.
Revisionsplikt i mikroföretag : ett förebyggande kontrollsystem mot ekonomisk brottslighet?
Background & Problem: The Statutory audit was initiated in the beginning of 1983 with the argument that it had a preventative affect against economic crimes. It is discussed whether the statutory audit should be abolished considering it brings major costs for small limited companies, also there are discussions however easing the regulation for these companies. What effect would it impose for the preventative work against economic crimes if the statutory audit is abolished?Purpose: The purpose with this study is to learn how an abolishment of the statutory audit among so called micro businesses will affect authorities? preventive work against the economic crimes.Demarcate: The study is demarcated to comprise only authorities that work with preventing economic crimes with help of the statutory audit and that will be affected of an possible abolishment, such as the Swedish Tax Office (Skatteverket) and the Swedish National Economic Crimes Bureau (Ekobrottsmynigheten).Methodology: The research is based on a qualitative approach with personal interviews with two representatives from each authority. The gathering of data has been done by researching literature and databases.Conclusions: The result shows that the statutory audit is significant for the authorities and their preventive work.
Konstruktion av säkerhetslagerför svänghjul
This thesis is the result of the investigation and solution of a mechanicalproblem regarding flywheel malfunctions. A flywheel is, in short, a devicethat relies on a rotating object?s moment of inertia to store energy overshort time spans. This project is part of the development of a fourthflywheel prototype at the division for electricity at Uppsala university,which uses magnetic levitation to keep a hollow cylinder rotating at veryhigh speeds inside a vacuum chamber. Should the magnets fail however, orsome other error occur that leads to an uncontrolled state of rotation, thecylinder needs to be stabilized mechanically by a device usually referredto as ?back-up bearing?.
Kroppstemperatur och vattenavdunstning via huden hos extremt underburna barn vid vård i kuvös och med kängurumetoden
Aim: To examine the reaction of extreme preterm infants with regarding to body temperature and transepidermal water loss during skin-to-skin care according to Kangaroo Mother Care (KMC) during the infant?s first week of life. Method: This was a descriptive quantitatively designed study, which was a pilot study within the framework of a larger project. Nine children, with a median gestational age of 24.91 weeks, were examined by measuring body temperature (axilla and skin temperature) as well as transepidermal water loss before, during and after KMC. Results: The study showed that skin temperature tended to rise during KMC, especially for those children who were nursed with KMC for more than 60 minutes.
