Skogssådd med tall och gran : effekter av fröegenskaper och skärm/hygge på plantbildning, överlevnad och tillväxt de två första åren efter sådd
Over the past few years the Swedish forestry industry has become increasing interested in Direct seeding. Although, in practice, this interest has been restricted to pine seed, the knowledge and techniques that have been developed for pine seeding can readily be transferred to spruce. Direct seeding is a method that is of interest to the forestry industry since it can lead to lower regeneration costs, denser stands and better root development than the more conventional planting method.
This study evaluated experiments that focused on Direct seeding of spruce in the northern Sweden. Skogforsk set-up the experiments in Gideå and Sävar in 2003.
Influence of prescribed burning and/or mechanical site preparation on stand stem density and growth of Scots pine stands above the Arctic Circle : results 9-19 years after stand establishment
Prescribed burning was commonly used for site preparation in Sweden to establish new forests until the 1960?s, when mechanical scarification was introduced. During recent decades the interest in prescribed burnings has increased again, mainly due to certifications of forestry stating that 5% of the regeneration areas should be burned on dry and mesic soils.
The objective of the study was to evaluate actual influence of prescribed burning compared to other site preparation on stand stem density, growth parameters and tree damages for Scots pine (Pinus sylvestris L.) after Direct seeding and planting. The study also attempts to simulate growth until first thinning.
INVASION DIREKTMARKNADSFÖRING
Direct marketing is an area within marketing that is growing rapidly. Many companies has realised the benefits of using direct marketing, such as receiving direct response from customers and gaining a better customer relation. The growth within direct marketing means that traditional mass marketing today face harder competition than ever.
This thesis examines and look in to three well recognised Swedish companies use of direct marketing. Our main purpose is to establish how companies spend their marketing budget between direct marketing and traditional marketing activities.
Plantetablering och tillväxt för sådd och planterad tall 2-5 år efter markberedning med harv eller Huminmix-teknik inom Holmen Skog distrikt Norsjö :
The objective of this work was to compare the environmentally gentle soil scarification technique Huminmix (with possibilities to do track-grinding/HMMspår, long-scraping/HMMlångfläck and mounding/HMMhög) with conventional disc trencher, concerning seedling establishment and growth of direct seeded and planted Scots pine seedlings. Inventories were made during June and July 2005, in 34 seeded and 6 planted stands from 2000 ? 2004 (1- 5 years old) of lichen- and myrtillus/vaccinum-type in Holmen Skog AB´s district Norsjö in Västerbotten. The Huminmix-technique had been used for HMMspår in the seeded stands and for HMMhög in the planted stands (HMMlångfläck has been used from the year 2006 for Direct seeding). The studied stands had been seeded with the same amount of seeds according to stand data.
Kommunal demokrati och medborgarinflytande i ett samhälle i förändring
The organisation of the municipalities is based on the principle of representation. It has previously been impossible to give the citizens more influence through direct democracy, but the information technology gives new possibilities and the choice of democracy model might no longer be obvious. Representation can be interpreted in many ways and there is a need for a more distinct definition of the rule that the municipalities shall be governed according to the principle of representation. It should also be further investigated how the new technology can be used to increase the use of direct democracy. The municipalities ought to work to supplement the representation with direct democracy in the form of active discourse with the citizens.
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.
Direktkrav vid ansvarsförsäkring i Sverige och i Finland : en bedömning av rättslägen samt en diskussion om direktkravets lämplighet
Two different claim relations arises with a damage covered by a liability insurance. The first claim relation is of course the one between the claimant and the liable as a claim for damages. The other claim relation arises between the liable in his capacity of insured and his insurer as a claim for compensation under the liability insurance. There is a tight connection between the two claim relations because of the fact that it is the claimant?s claim for damages that gives rise to the claim for insurance compensation.
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.
Design of a Direct-conversion Radio Receiver Front-end in CMOS Technology
In this Master's thesis, a direct-conversion receiver front-end has been designed in a 0.18um CMOS technology. Direct-conversion receivers (DCR) have obvious advantages over the heterodyne counterpart. Since the intermediate frequency (IF) is zero, the problem of image is circumvented. As a result, no front-end image reject filter is required and the channel selection requires only a low-pass filter, which makes it easy to integrate directly on chip. However, the DCR also suffers from several drawbacks such as extreme sensitivity to DC offsets, 1/f noise, local oscillator (LO) leakage/radiation, front-end nonlinearity and I/Q mismatch.
Att placera konsumenter i fack. En studie i kategoriserande direktmarknadsföring.
This thesis examines the extent to which segmentation and categorization in the context of direct marketing is an efficient way for a company to enhance its marketing effectiveness. The thesis is built on social identity and categorization theory, and tested by using statistical analysis. The conclusion is that segmentation and categorization is indeed an effective way of conducting marketing campaigns..
Knapptryckardemokrati : Om synsätt på IT-stödd demokratiförnyelse
With the increased significance of information technology (IT) in today?s society the term ?electronic democracy? (e-democracy) has gained much importance within the democracy theory. Naturally, there are several competing views on how the technology should be used for democratic purpose. One aspect of this is the somewhat revitalized claim for direct democracy in accordance with the hypothetical opportunity to finally realize it as a democratic system. The ideal of direct democracy combined with the almost total credence in the potential of technology constitute the idea of a ?push-button democracy?.
Det finns ju utrymme för tolkningar : En kvalitativ studie om handlingsutrymme i socialjoursverksamhet
The overall purpose of this essay was to provide a better understanding of the importance of discretion for social workers in direct social services. To answer the purpose three questions were formulated: (1) How do social workers define and describe their discretion and their ability to independently accomplish their work? (2) How do social workers experience that workplace organization, policies and economic conditions interact with their discretion and (3) How do social workers experience that the interaction with the client can affect how they use their discretion in the individual case? The method used was qualitative interviews. The theoretical framework was Michael Lipskys (1980) Street-level bureaucracy and the four themes organization, professional role, skills and interaction.The results showed that the respondents, although they did not consider themselves to be affected by the economy still adapted to budget restrictions when they said that they were cost conscious in their work. This adjustment to budget framework could possibly be what made them not feel limited in their work.
Rättfärdigandebegreppets potentiella tillämpning vid direkt könsdiskriminering : en analys av den EG-rättsliga diskussionen om utökade möjligheter till rättfärdigande
Sex equality law within the European Union is well developed and has since the Rome Treaty, given rise to several directives and other judicial acts on this matter of community law. The concepts of direct and indirect discrimination emerge from the general principles of Equal pay and Equal treatment and have been codified and amended several times until present.The lasts years, authors within the field of Equality Law has been pointing out that there is a common desire for simplification of discrimination law in Europe. The question has arisen whether this simplification could be implemented trough the introduction of a general justification defence for direct sex discrimination.The concept of direct sex discrimination - when a person of one gender is treated less favourably, on the grounds of gender, than a person of the other gender would be treated in similar circumstances - leaves no possibilities for such justification today. Indirect sex discrimination ? which arises from the equal application of neutral rules that shows an adverse impact on one group ? can be justified if the rule answers to true requirements of the job.Does the proposition that direct discrimination should be justified find support in the inconsistency of the present legislation? This paper will examine this and other questions concerning the wish for a general justification defence through studies of case law from the European Court of Justice as well as differing opinions from authors within the field of equality law..
Jordbearbetningsstrategier på hösten inför vårsådd på tyngre lerjordar :
It is important for today?s farmers to minimize the costs for crop establishment, because
of decreased prices and support from the EU. Farmers, who plow in autumn on heavy
clay soil, often do some kind of tillage in autumn to get better soil structure before
spring seeding. This is especially important when growing small seed crop, e.g. sugar
beet and oil plants.
Soundtrack till Ont blod
Denna slutreflektion beskriver arbetet med att designa soundtracket till filmen Ont blod, en novellfilm som spelades in på Gotland hösten 2010 av Andersson/Wilén produktion. Vårt arbete har varit postproduktionen av allt ljud, inklusive musikkomponering. Syftet med arbetet var att testa och jämföra de två metoder av surroundmixning (direct/ambient och direct-sound all round) för film som Holman (2008) beskriver, för att sedan välja den som passar vår produktion bäst. Reflektionen är skriven i två delar. Den första delen handlar om produktionen i sin helhet och om projektplanen.
