Örter - en nisch? :
A tight economy and a keen competition force the Swedish agricultur to do a structural rationalization. The quantity of farmers is less but the units are growing. How to make money I think some kind of niche is necessary. In my examwork I have locked how to farm herbaceous plant and the marking of herb to feedstuff for horses.
Today health food and alternative medicine are accepted to use and there is an increase in demand.
The Swedish market for herbaceous plants to horses is small and the products are mostly imported. But there is a group of consumers who is willing to pay a higer price for Swedish cultivated herbs.
The only way to find out which herbaceous plants I could cultivate is to make a test cultivate.
I think that the market for herbaceous plants is growing.
Metodik för resistenstest i renkavle : en studie om herbicidresistens; mekanismer, detektion och åtgärder
Herbicide resistance is the result of an evolutionary process where a population gradually changes from being susceptible to being resistant to an herbicide. The resistance mechanism is usually a change in the biochemistry of the weed, but in some cases changes in morphology or growth rhythm. The change is caused by random mutations. Two resistance mechanisms are found in black-grass; target site resistance and metabolic resistance.Black-grass is a tufty, winter annual grass weed, which is mainly found in milder climates. Black-grass is a big problem in Southern Europe.
Det finns 10 sorters människor - de som förstår och de som inte förstår. : Lärares uppfattningar om matematik och matematiksvårigheter.
This report is an attempt to clarify how religious and non-religious views-of-life [livsåskådningar] are created through the collaboration and opposition of religious and scientific elements/ideas. This with the hope of reaching a fruitful result related to the solution of world-view related conflicts, such as the ones existing between science and religion, on an individual and societal level.This is accomplished with the help of two assertions: (1) Mankind has a need to explain its existence and surroundings. (2) Religion and science has their origins in the same seed and aim to serve the same purpose, or function. Together these two assertions lay the theoretical foundations of this report which implies that all humans have an innate need of sustaining a stable world-view.The result of this report is that a final solution to world-view related conflicts are beyond reach as our mental and physical nature limits us. However there are strategies for minimizing world-view related conflicts effect on society..

Orienterare, framtidens naturvårdare? : Inventering av markstörningar i samband med O-Ringen i Skåne 2014
As an increasingly rationalized forestry and agriculture have human interference in the form of tradition, grazing and use declined. There is a strong link between biodiversity and disturbance of the landscape. In sandy soils many insects and plants require exposed sand to survive while the disorder may contribute to seed dispersal in the woodlands. On behalf of O-Ringen Skåne 2014, a study of the interference from orienteering in sandy soil and the forest during competitions conducted. The aim is to clarify the interference of which orienteering runners contributes, through to inventory presence before and after the competitions in the bottom and field layer in three locations.
Markberedningsresultat och plantbildning med såddaggregaten Humax 2-4 och KSM-såddskopa
Fördelarna med skogssådd är bland annat att de kan ge stamtäta bestånd med potential att producera träd med bra vedegenskaper och bättre utvecklade rotsystem samt att sådder har en högre biomassaproduktion per ytenhet jämfört med planteringar. Nackdelar som kan nämnas är att de ofta täta förbanden ger ökade kostnader vid eventuella röjningar och att föryngringsresultatet är mera osäkert för sådd än för plantering.Mekaniseringen av skogssådden startade under 1970-talet. Humax och KSM är två kranspetsmonterade aggregat för skogssådd. De har utvecklats för att användas på marker med svår ytstruktur där dragna såddaggregat som harv och högläggare har svårigheter att skapa tillräckligt mycket lämplig såddbädd på grund av att aggregatet inte kommer ner mellan hindren eller att basmaskinen inte klarat av att köra över hela arealen. Fördelen med KSM och Humax är att aggregaten är kranspetsmonterade vilket gör att föraren väljer var aggregatet skall markbereda och på det viset kan markberedningen göras mellan hindren samt att kranarmens räckvidd gör att basmaskinen inte behöver köra över hela arealen som skall markberedas.
Risk för spridning av ogräsfrö med rötrester : en litteraturstudie
With an increasing production of biogas follows an increased amount of digestate. This could potentially be a valuable source of fertiliser with the destruction of weed seeds as a possible advantage. However, there have been some concerns regarding the product still containing viable seeds of weed.
In this Bsc thesis the results of previous research on the fate of weed seeds in biogas production is summarized. It is also a comparison of research on the effect of similar processes such as silage, compost or animal passage on seeds. The purpose of this is to evaluate risks of spreading viable seeds, potentially problematic species and perhaps to find out how to eliminate the risks.
The literature review revealed that previous research mainly indicates low risks regarding many of the tested weed species, but not all studies show the same result, therefore extended research on the subject is desirable.
Optimering av tippram : tillhörande lastväxlarvagn Parator LX10-20
Norrborns Industri AB in Bollnäs manufactures truck trailers with the brand Parator. One of their trailers is Parator LX 10-20. The trailer is designed to transport hooklift containers with the option to tip loose goods such as gravel, asphalt and seed. The container is mounted on a frame which is placed on the chassis. To reduce weight a redesign of the trailer is needed.
Vem är normal?
My project is about attitudes towards disabled people, about our fear for those who are different, about acceptance, ideals and normality.My inspiration has been prosthesis, and mostly people that are born without limbs. Through my research I have come across a lot of questions. Such as, why is a prosthesis so important and for whom? Why is it so important to be normal? What is normal and for who? People that are born different se upon themselves as normal, until they realize that others don?t. Many of them want to learn how to deal with life without prosthesis. And therefore they reject these. Sometimes the prosthesis is aids that are highly necessary.
Rotningsstimulerande effekt och kemisk analys av vattenbaserad extraktion av vedartade och örtartade skott av Salix smithiana Willd. :
Cuttings of Lonicera xylosteum L. were treated with willow extract to study the response in rooting capacity. The extracts were prepared by mixing chopped pieces of Salix x smithiana Willd. with water in a warring blender. The investigation comprised 2 types of salix extracts based on differences and dynamics between twigs in winter dormancy and twigs with new shoots.
To explore the rooting response, three tests were made.
Marknadens inverkan på behovet av företagsstöd - en studie av sex uppstartsföretag
In efforts to strengthen local economies, business development programs are often a way in which governmental organizations and state affiliates try to facilitate innovation and successful entrepreneurship. There is a mutual interest from both the public and private sector that these funds are put to good use. Extensive research has been conducted with the focus of the general effect of public support programs. However, not much research has been done on what external factors affect the situation for receiving businesses. This study attempts to examine whether one specific such factor, the level of maturity on the markets that the recipients operate in, has a discernible effect on the needs for different types of entrepreneurial support.
Reproductive physiology of the female cat
The cat is one of our most common pets. Understanding the reproductive physiology of the queen is important, not only for the knowledge of our domestic cats but also for wild undomesticated feline species, many of which have been reported endangered. Understanding the mechanisms
behind the estrous cycle, ovulation and pregnancy is also important for handling the feral cat populations that are a problem in several countries. The purpose of this literature study is to look into the hormonal patterns of the reproductive physiology of the female cat, with focus on
ovulation, pregnancy and pseudo-pregnancy, and from this information determine in which fields more research would be needed.
The female cat is seasonally polyestrous in Sweden, meaning that she can have several estrous cycles during the breeding season but goes through a long period of reproductive dormancy during the darker months of the year. The queen is considered an induced ovulator, with
copulation triggering the release of luteinizing hormone (LH) from the pituitary gland needed for ovulation.
Sådd av tallfrön med vattenryggsäck : en laboratoriestudie
Föryngring av skog är en nödvändig, men kostsam åtgärd och därför är det eftersträvansvärt att hitta en föryngringsmetod som är både kostnadseffektiv och ger en bra föryngring. Ett sätt att få en billigare föryngringsåtgärd är att använda frösådd. Vid en lyckad sådd gör det stora plantuppslaget att plantorna får bra förutsättningar för god kvalitet. Dessa plantor får dessutom bättre rotutveckling och stabilitet än planterade plantor. Användningen av skogssådd är dock begränsad av bl.a.
Jonatan - tronföljaren som inte blev kung : om en relation och dess konsekvenser
The story of Jonathan and David is a part of the deuteronomical view of Israels history from the occupation of the holy land all the way to the exile in Babylon. I am aware of that this is not true history, but it is nevertheless interesting to ask oneself: Why are those people a part of the deuteronomical history? What was the meaning in telling the story in this way?Exegetes and researchers are trying to give the relationship between Jonathan and David a place in the political realm, but here I have used several sources to show that it is not only a political story, but a loveaffair, where Jonathan is pictured as a submissive woman and thereby excludes himself from the throne of Israel. David on the other hand, acts as the perfect man, who is in command in spite of his youth. He does not break the rules of the patriarchal society, where the relation between two men was accepted as long as the older one did not play the womans role.
Fånggrödor i Norra Östersjöns vattendistrikt
70 % of the lakes and waters in the water district of northern Baltic Sea do not reach the
requirements for good ecological status. This is mostly due to eutrophication caused by a too
high deliverance of nutrients from agricultural land or effluents. Losses of particulate
phosphorus through water erosion contribute to a great extent to this eutrophication. In the
action plan for the water district cover crops are mentioned as a measure for reducing losses
of phosphorus from arable land. This paper reviews the possible effect of cover crops in the
water district and discusses what crop that would be most suitable.
