Kvalitetsförändringar hos rajsvingelsorterna Hykor, Perun och Paulita under första skörd :
Today, high-yielding leys of good quality are a must for Swedish dairy and beef enterprises if they are to become profitable. Thus, it is of interest to evaluate the quality of the recently released high-yielding Festulolium hybrids ((Festulolium braunii (K.Rich.) A.Camus). The aim of this project was to determine at what phenological stage three different Festulolium hybrids should be cut in order to get the highest nutritional value. The hybrids studied were Hykor, Perun and Paulita. In the study I also investigated if leaf proportion of the crop could be useful for predictions of the crop content of metabolizable energy.
The cultivars were grown in plots within a variety trial with ryegrasses.
Lärare i idrott och hälsa? : En etnografisk studie om begreppet hälsa i ämnet idrott och hälsa
Health is a complex concept and therefore difficult to define. The concept today playsan important role in society as well as in school, due to the inactivity of today?s youth. Thelatest curriculum for the compulsory school, Lpo 94, has increased the focus on the concept ofhealth, as a part of the physical education, but how the teacher chooses to construct theeducation is still up to each individual, which leads to a vast room for personal interpretation.This is the starting-point of our qualitative, ethnographical, study, that has resulted inthis composition. By passively participating during four lessons as well as interviewing twoteachers in physical education we have been able to analyse how the education regarding theconcept of health was constructed.
Personlig träning på egen hand
AbstractThe purpose of this essay was to determent if the authors? idea to replace a personal trainer with a training program, which is provided by software, is viable and if there is a market for such a product. The method that was used, included eight people who enrolled in a training program which were designed by the authors in Microsoft excel. The programs were based on principals of periodization, and included the phases: anatomic adaptation, hypertrophy, maximum strength and muscle definition. The training program was personal and based on individual goal setting.
Vårtor på mjölkkornas spenar :
The reason why I choose the subject ?Warts on teats of Dairy Cows? was because the
herd I work with has big problems with skin-complaint on teats and udder.
So I found it interesting to try to find the reason why the cows look like they do and
even to find a way to relieve the trouble.
The examine work included both a literature research, an experimental test,
concerning a comparison of different teat sprays and also an inquiry-research about
the occurrence of warts in practical herds in order to collect as much facts as possible.
Three companies, selling different types of teat disinfectants, were willing to sponsor
the teat dipping experiment. The aim of the experiment was to see if any special
disinfectant had more pronounced healing effects on teat warts. The date for the
experiment was 18th December 2004 to 22nd January 2005, which was going to be 5
weeks.The experiment was carried out in the herd of Ola and Eskil Carlsson in
Fjärlöv, Hässleholm.
The three compared teat spray chemicals were; Nova Viri Sun, Nardosept, and
BlockadeTM. These chemicals were compared to one control group, which teats were
treated with the ordinary chemical normally used in the herd, i.e.
Biological control of Fusarium wilt on tomatoes : use of Bacillus subtilis and interactions with the earthworm Pontoscolex corethrurus in a Kenyan highland soil
It is important to investigate the potential of biological control measures in agricul-ture, especially where economic issues restrict the use of expensive inputs or when there are environmental concerns about toxicity of agrochemicals. The bacterium Bacillus subtilis has proved promising as a biocontrol agent (BCA) in suppressing various plant diseases and it has also been shown to promote plant growth in certain cases. During this study, the effect of B. subtilis on Fusarium wilt (caused by the fungus Fusarium oxysporum) on tomatoes, as well as its effect on the earthworm species Pontoscolex corethrurus was investigated. Furthermore, the combined ef-fect of the BCA with P.
Biological control of powdery mildew in greenhouse produced cucumber : an evaluation of two microbiological control agents
Powdery mildew is a serious problem in both field and greenhouse cucumber production and
can cause serious infection and radically reduced yields. Today, powdery mildew is the main
disease in greenhouse produced cucumber.
Disease control should preferably be both efficient and environmentally friendly, which is not
easy to achieve at all times. Alternatives to chemical control of powdery mildews are biological
control, physical control, non-fungicide control and cultivation of resistant or tolerant varieties.
Biological control can be described as the suppression of damaging activities inflicted
of a harmful organism by one or more other organisms, which are called antagonists or natural
enemies. In Sweden, there are currently no registered biological control products available
to control cucumber powdery mildew.
The aim of this study was to investigate the effect of two biological control products in order
to evaluate their ability to prevent or reduce powdery mildew infection to an acceptable level
in greenhouse produced cucumber. In the experiments, different application regimes were also
studied.
Crowdsourcing som tillämpningsmetod hos svenska arkivinstitutioner : En kvalitativ undersökning ur ett maktperspektiv
In this thesis I have chosen to study the use of crowdsourcing in Swedish archival institutions as well as the influence this methodic platform has on the work of modern archivists. This also raises the question whether the nature of the platform is in any way influenced by the attitude working professionals might have towards crowdsourcing as a legitimed working method. This investigation is based on case studies and interviews with archivists from select Swedish institutions and also the methodology of two now ongoing crowdsourcing projects.The theoretical framework on which this composition is based comes from the work of Gregory Asmolov and his work on crowdsourcing platforms and their functionality as tools of governing. Cultural-Historical Activity Theory (CHAT) is applied to analyze how the method of crowdsourcing is utilised by archival institutions and influenced by their daily routine in conjunction with Governmentality as the chosen way of studying how these platforms might control their users.From the results of the performed case studies, two discourses emerged based on the view on quality concerning gathered information amongst the involved subjects. The first of these discourses places it´s trust and faith in users themselves where validity is of a lesser concern than the actual availability of information through the concept of ?wisdom of the crowds?.
Metanpotential för alger och bioslam blandat med pappersfiber
In this thesis the methane gas potential of three different substrates, two algaes Saccharina latissima and Laminaria digitata and biosludge mixed with paper fiber was studied. This was done by batch experiments in a laboratory environment to examine the gas production and composition of the produced gas.Biogas production is a complex anaerobic digestion process in which various microorganisms decompose the substrate in steps and at the end produce biogas and a residue. Many factors affect the production of gas, for example the substrate content, temperature and pH in the digester.The analysis of methane potential were divided into two experiments. In experiment 1 substrates were digested along with inoculum from Växjö waste water treatment plant in a temperature of about 37 ?C.
Hur ser Läget ut egentligen? : En studie om arbetsmiljön inom byggsektorn
This study includes several purposes which are to describe the concept of working environment, explain who is responsible for its functioning and how the working environment should look like. Other purposes the study have is to investigate how the working environment is in both Swedish and the two investigated companies construction sites and to share some operators proposing measures for the shortcomings and problems that exist in the construction sector working environment. To achieve these purposes was a qualitative study made with unstructured observations, interviews and survey where three construction sites were observed. The result shows that the concept of the working environment cover many aspects and is essentially about the environment we live in and experience in our work and this environment can be both an indoor as an outdoor environment. In this work, the concept is divided into four areas; it is the physical, the ergonomic, the psychosocial and the chemical.
Tystnadens spår : En läsning av tystnadens estetik och etik hos Mirjam Tuominen och Gunnar Björling
This bachelor thesis engages in the question of silence in the writings of Fenno-Swedish modernists Mirjam Tuominen and Gunnar Björling, silence being understood as both a poetic theme and a question of literary form. Alongside this exposition runs a discussion about the possibilities and impossibilities of interpretation in the field of academic literary studies. This query is connected to the different ideological positions of the two writers, conjoined by ideas about anti-comprehensibility. Considering certain weaknesses of classical hermeneutics as well as the theory of deconstruction, especially in the case of reading poetry, this thesis tries to point out possible routs for a practice of a more dynamic interpretation, with special regard to understanding the trope of silence in the modernist poetry of Tuominen and Björling.The composition explicitly applies a ?method of wandering? inspired by Maurice Blanchot?s understanding of the priests of Dionysus in Hölderlin?s writings ? maundering in the holy night ? as a metaphor for a critique-in-the-creating.
"Jag skulle vilja att syv förklarade mer, liksom..." : En kvalitativ studie om samtalets betydelse för utlandsfödda elever
Syftet med uppsatsen är att undersöka vilken betydelse och påverkan samtalet med studie- och yrkesvägledaren har för utlandsfödda elever med icke svenska föräldrar som är sent anlända till Sverige. En kvalitativ forskningsmetod har används. Fakta har inhämtats via elevintervjuer bestående av åtta informanter från en mindre kommun. Urvalet utgjordes av grundskoleelever i årskurs nio som gjort sitt gymnasieval samt gymnasieelever från årskurs ett och årskurs tre. Resultat och analys indikerar att eleverna tycker att samtalet är betydelsefullt, eleverna får svar på frågor, får faktainformation och detta leder till ett bättre beslutsunderlag i valsituationer.
Den pedagogiska samlingen i förskolan : En kvalitativ studie om förskollärarnas tankar kring samling
The purpose of this work is to explore and illuminate the circle times function and importance of preschool by the pedagogue perspective and the circle time design in relation to children's age group composition. The study questions are:What is the purpose of circle time in preschool educational activities according to the teacher and how does the teacher look at his own role?How do the teachers plan, design and perform the circle time of small children and big children's section? What similarities and differences exist?This is a qualitative study based on interviews with four preschool teachers and observations of their circle times. Research and theories showed that the circle time is a social training, provide a sense of community and is a ritual that gives a good daily rhythm.The results of the study demonstrate that the circle time is an important routine that occurs for a short time daily in early childhood education. The circle time organizes and structures the day for both children and staff group.
En studie av sedimenttransport, död ved och kantzoner längs två vattendrag i Kilsbergen - från skog till slätt :
Headwater streams are affected by anthropogenic impacts at multiple scales.
One aspect of human impact is sediment transport associated to the
abundance of stream structures as large woody debris and the composition
of the riparian zone from forest to agricultural landscapes.
Riparian buffer zones and stream structures like dead wood are considered
as generally important structures for protection against an increasing
amount of sediment particles in the water. Hence, in this study these
structures were quantified in thirty different stream segments on land and in
the water.
To measure the transport of sediment Whitlock-Vibert boxes were used in
three different types of landscapes; forest, transition and fields. The boxes
were left in the stream segments for three months, the taken up and dried
and weighed. The results showed that the transition-land in Frösvidalsån
had the highest sediment transport. The second highest transport of
sediment was in Blackstaån at the fields.
Hållbar vattenkraft i Nissan : En förstudie och konsekvensutredning över förutsättningarna för ökade vandringsmöjligheter med nya fiskvägar.
The hydropower from Nissan River is of national interest and produces annually 230 GWh from the twelve power stations in the main flow. For modified waters a consideration between the power production and the biological values has to be made. This reports serves as a pre-study for Nissans Vattenråd. It tries to evaluate some of the biological values in the Nissan basin and map the power production in the area. And the size and value of lost power production from new fishways for the twelve stations in the main flow.The investment of new fishways is calculated using simplified templates with values from the business.
Skolkuratorers anmälningsskyldighet om barn som far illa
Sweden has an obligation to report child abuse suspicions to Social Services. According to Socialtjänstlagen (swedish constitution) 1 § Chapter 14, all employees in agencies affecting children, such as schools, have a responsibility to report their suspicions. Research shows that many abuses are not reported. The consequence of this is that Social Services does not hear about all cases of abused and harmed children. One profession where reporting is mandated is school counselors.
