Utveckling av en diameterklassmodell för grandominerade bestånd i Sverige :
Growth models are very useful tools for forestry to predict growth and yield. With growth models and optimising tools you can manage forest stands in a way that maximize benefit and income. There are three major types of growth models. Stand models; stage structured models and single-tree models. The most advanced models give the most accurate forecasts.
Do 25 years old skid tracks restrict growth and survival? : a study on growth conditions for the planted regeneration in a rainforest rehabilitation project
The rainforests of the world are important not only to the countries in which they grow but to the world as a whole. They influence oxygen and water circulation as well as carbon sequestration which in turn affect global radiation and global warming. The forest also have great value and in Malaysia as in many other tropical countries large volumes are harvested which leaves great areas of degraded forest with little growth and biological diversity. Due to their low financial value these forests are often transformed and used for other purposes than forestry such as oil palm plantations.
The trees are often transported out of the forest using large bulldozers. They are heavy which causes compaction of the forest floor and during transport the top soil layers are moved to improve mobility.
Hur hushållas det med mark och vatten? en studie av tillämpningen av hushållningsbestämmelserna i 3 och 4 kap MB
The national spatial planning guidelines and the subsequent legal regulation in the Natural Resources Act and the Environmental Code has been a part of the Swedish planning system for almost 40 years. In the recent years, critics have claimed that the regulations are outdated and does not work the way it was intended. This paper examines closer why it is perceived that the regulations does not work, with a focus on how the national interests are managed in the municipal planning. Why is the national interests not applied in the municipal planning as intended? Is the error in the system or in the implementation of it? The aim of this essay is to study the gap between theory and practice by studying how the land management provisions in the Environmental Code is applied in five selected municipalities.
Effektivare samråd mellan rennäring och skogsbruk : förbättrad dialog via ett utvecklat samrådsförfarande
Enligt § 20 i skogsvårdslagen (1979:429) skall berörd sameby beredas tillfälle till
samråd då en föryngringsavverkning med efterföljande åtgärder samt avverkning för
byggande av skogsbilväg skall ske inom åretruntmarkema1. Skogsägare som är FSC
certifierade2 skall inom hela renskötsel området, enligt FSC-standard, bereda berörd
sameby tillfälle till samråd om skogsvårdsåtgärder samt avverkning för byggande av
skogsbilväg och där visa den hänsyn som följer av skogsvårdslagen.
Idag sker samråd mellan rennäring och skogsbruk i varierande omfattning och
med varierande resultat som följd. Då en skogsägare skickar en ansökan till
skogsvårdsstyrelsen om tillstånd för avverkning, skall berörd sameby, enligt lag, ha
beretts tillfälle till samråd och därmed skall tillhörande samrådsprotokoll bifogas
tillståndsansökan. Vid en vanlig avverkningsanmälan är det frivilligt men storskogsbruket
bifogar ofta samrådsprotokoll ändå.
Sanningens ögonblick : En fallstudie av kvalitetssäkring i tjänsteföretag
AbstractTitle: The Moment Of Truth; A study of service quality assuranceAuthors: Fanni Helminen and Linda ElsborgLevel: Bachelor Thesis in Business Administration, C-level.Advisor: Lars- Johan Åge and Jens Eklinder FrickDate: 2014- JunePurpose: Quality assurance has become a vital concept and an important tool to ensure that employees are able to deliver high service quality. The purpose of this study will be to elucidate how service companies can apply the use of sevenfundamental features supporting service quality in their quality assurance; recruitment and selection; training, teamwork; empowerment; performance appraisals and rewards; communication, and culture (of the organization). Furthermore, we will illustrate how the type of business entity, organizational structure and organizational resources afflicts the seven features.Method: Method: We will, from a hermeneutic point of view, apply and qualitative deductive research method. Data have been collected through a case study. The data have been transcribed and the analytical method has been selected based on the conducting purpose.
Vedrötor i stadsträd : biologi, detektionsmetoder och förebyggande åtgärder
Urban trees have very little in common with trees on natural sites, such as forests or pastures. Trees in urban environments are often planted in packed soil and in small volumes. This can lead to decreased availability of water and oxygen, as well as deteriorated ability for the soil to store nutritional elements. Also above ground the tree usually have limited space in cities. Regulations on free height over roads and cycle tracks demands high stems at an early stage of their development.
Holografisk Video
Detta examensarbete utgår ifrån en artikel i vilken en metod för att skapa holografisk video beskrivs. Syftet med arbetet är att återskapa denna metod. Metoden bygger på projicering av hologram med hjälp av delar från en projektor, en laser och några linser.Först görs en litteraturstudie för att få förståelse över hur metoden fungerar. Här behandlas hur ögat ser djup och vilka olika typer av displayer det finns för att återge tredimensionella holografiska bilder. Vidare beskrivs skillnaden mellan optisk och datorgenererad holografi.
Hur hushållas det med mark och vatten? en studie av tillämpningen av hushållningsbestämmelserna i 3 och 4 kap MB
The national spatial planning guidelines
and the subsequent legal regulation
in the Natural Resources Act and the
Environmental Code has been a part of
the Swedish planning system for almost
40 years. In the recent years, critics have
claimed that the regulations are outdated
and does not work the way it was intended.
This paper examines closer why it is
perceived that the regulations does not
work, with a focus on how the national
interests are managed in the municipal
planning. Why is the national interests
not applied in the municipal planning as
intended? Is the error in the system or in the
implementation of it?
The aim of this essay is to study the gap
between theory and practice by studying
how the land management provisions in
the Environmental Code is applied in five
selected municipalities. The aim is also to
find interesting issues for futher studies of
the topic.
Plantors och träds tillväxt efter schackrutehuggning och i konventionellt trakthyggesbruk
Eftersom hållbart skogsbruk innebär att man i skogsbruket tar lika stor hänsyn till de ekologiska och sociala aspekterna som de ekonomiska är det viktigt att utvärdera alternativ till det konventionella trakthyggesbruket för att säkerställa att alla värden i skogen uppnås. Ett så kallat schackrutesystem, eller Chequered-Gap-Shelterwood-System (CGS-system), är ett system där träd avverkas i mindre luckor som sedan alterneras med motsvarande skärmställningar. Detta skapar ett tvåskiktat bestånd med schackrutemönster. CGS-systemet är ett skötselförslag där fördelarna från både trakthyggesbruk och kalhyggesfritt skogsbruk eventuellt skulle kunna kombineras. Målet med denna studie är att utvärdera tillväxten av plantor och träd i CGS-system.

Addressing increasing global environmental problems requires greater resource efficiency, and one way of working towards this is through industrial symbiosis. Industrial symbiosis means that companies collaborate through sharing of resources for collective benefits. The documented benefits of working with industrial symbiosis indicate that there is potential for companies to operate commercially with facilitation of industrial symbiosis. An interesting company to study within this context is Econova. Econova operates within the recycling and gardening industry and has been identified as a possible catalyst for industrial symbiosis.
Till synes orörd skog : naturvärden och kulturhistoria i Rekdalen under 400 år
Nature conservation has for a long time been founded on the assumption that high ecological values depend on low human impact. In Sweden this has led to forests with these characteristics being strictly protected from human influences. However, it is also known that historical land-use can enhance ecological values in forests. Mountainous forests in Sweden, which have not been affected by modern forestry, have for a long time been considered as untouched by people. However, forest history research has in recent years shown that even these areas have been used by people for a long period of time.
Sheep enterprise budgets : beneficial planning tools within Agriwise Macedonia
Generally in Macedonia keeping farm records and farm business planning is not often practiced like an ordinary activity in farming. Therefore one of the crucial things to do it is to comprise and continuously practice record keeping of farm data. The efficient and justified farm business planning should be based on farm records about the previous work of the farm, which will bring a structured approach for planning all the activities, as well as provide a good basis for attracting investors and creditors for the additional expansion of the business.Given that sheep breeding holds an important part of the livestock production in Macedonia, there is a need for adding analytical sheep enterprise budgets to support the farm business planning process at sheep farms.The aim of this research was to develop sheep enterprise budgets created on the best production practice for Macedonian conditions of breeding and test their applicability into the farm business plan model Agriwise Macedonia. The sheep budgets were composed with a process of data collecting consisted of direct farm data (for the cases), expert's consultation and relevant desk research, as well as a literature study. The aim of doing it was to attain more accurate calculations of the enterprise budgets, which will result in a more precise outcome in the farm business plan model Agriwise Macedonia.
Välkommen : vackrare infart till Vilhelmina
The purpose of this thesis is to show how a good approach can be designed, focusing on the southern approach to the Swedish town Vilhelmina. Prior to the car being part of everyday life, the approach was a road where the town showed itself from the very best side. When the amount of traffic increased, so did noise and other disturbances, and as a consequence industrial areas replaced the residential buildnings at the approaches. Today, the pendulum is turning back and in recent years the approach is regarded as a place to introduce the town. The approach is also the place where cars should slow down from the speed of the main road to the speed of the city.

Enskilda privata skogsägares inställning till skogsgödsling i Västerbottens län
För att få en hög produktion i skogen krävs god tillgång på kväve (N). I svenska ekosystem är växttillgängligt kväve den mest begränsande tillväxtfaktorn på fastmark, vilket gör skogsgödsling till den enda skötselåtgärd i Sverige, som rätt utförd kan öka tillväxten i skogen på kort sikt. Enskilda privata skogsägare är den enskilt största gruppen skogsägare i Västerbottens län såväl som i Sverige som helhet. Denna grupp av skogsägare har således stort inflytande över hur den svenska skogen sköts och avkastningen från denna.
Syftet med detta examensarbete är att redogöra för enskilda privata skogsägares inställning till gödsling av skogsmark i Västerbottens län. För att kartlägga skogsägarnas ståndpunkt i frågan sattes en enkät ihop som skickades ut till slumpvis valda privata skogsägare i länet.
I likhet med tidigare studier visade denna enkätundersökning att de enskilda privata skogsägarna inte gödslar i någon större utsträckning.
