Efficacy of Phlebiopsis gigantea treatment on spore infections of Heterobasidion spp. on Larix X eurolepis
The effectiveness of Phlebiopsis gigantea to prevent spore infections from Heterobasidionannosum and Heterobasidion parviporum on hybrid larch stumps were investigated in fivestands in southern Sweden. All sites are former forest land and the age of the trees wasbetween 9 and 13 years.The study was implemented in August 2010, a month where spore dispersal should be great.The five sites were located in previously un?thinned monocultures of hybrid larch. The sporeload in the air was studied with the help of spore traps from three different tree species;Norway spruce, Scots pine and hybrid larch. A total of 146 spore traps, evenly distributed inall five sites were analyzed.
Hemingways kvinnor : stereotypa eller en spegling av sin tid?
This essay is about the female characters in the books of Hemingway. Are they as simple as some critics say, or are they more complex beings, and which ones of the women in the life of Hemingway, can be noticed in his female characters? In the work with this essay, biographies of Hemingway as well as a few of his novels have been studied. The selected novels are Farewell to Arms, Across the River and into the Trees, The Sun also rises and the short story The Snows of Kilimanjaro. The selection was based on the fact that these stories contain good female characters.
Landskapsplanering och konnektivitetsförbättringar inom värdetrakter i Västerbottens län :
According to the Swedish strategy for forest protection, additionally 40 000 ha productive forestland will be protected in the county of Västerbotten, between 1999 and 2010. A national project was carried out to distinguish the proportion of forest with a high biological value, in all counties. The project resulted in demarcation of small landscape areas or small ?biological value regions? (bvr), with higher concentrations of forests with conservation values and red listed species than the surroundings. In Västerbotten, 26 such bvr?s were identified and the Counties Agency and Forest Agency in Västerbotten developed a regional strategy for forest conservation to standardize the forest protection process.
It's strength lies in the speed and (surprisingly) it's consistancy. All you need to go off is a way to put Worldgorger into your graveyard (Cabal / Thoughtseize yourself, Entomb) and a reanimate spell (Animate Dead, Necromancy, Dance of the Dead).
Det genomgripande syftet med denna uppsats var att synliggöra ungdomsassistenternas arbete på Lyrans asylboende samt att se vilken relevans olika kunskapsformer har i detta. Utifrån frå-geställningarna handlade studien om att beskriva ungdomsassistenternas arbete samt att förtyd-liga gemensamma aspekter i arbetet med EkB. Jag utgick också från att studera ungdomsassi-stenternas beskrivelser av lyckosamma hjälpinsatser samt vilken kunskapsform som assisterar dessa.Empirin i denna studie baseras på mina tidigare erfarenheter av arbetet med ensamkommande flyktingbarn och ungdomar samt resultatet från totalt fyra intervjuer med ungdomsassistenter på Lyrans asylboende för ensamkommande barn och ungdomar. Jag har vid insamlandet av empirin utgått fån tre olika kvalitativa metoder vinjett, semi-strukturerad intervju samt en egen utarbetad interaktivt-strukturerad intervjumodell. Jag har förankrat personalens beskrivningar med aktuella forskningsstudier samt analyserat deras arbete utifrån de fyra kunskapsformerna episteme, techne, fronesis och tacit knowing.Resultatet synliggjorde delar av personalens praktiska och utförande arbete med EkB och fram-förde viktiga gemensamma teman i detta.
Tame animals in the wilderness : livestock grazing around summer farms in Jämtland, boreal Sweden 1800-2011
The forest and mire landscape surrounding the north Swedish villages have been of fundamental importance through time for the farmers. In the Scandinavian summer farm system the forest and mire pasture was used to its full potential. The system consisted of smaller summer farms some kilometres from the main farm in the village, and were the livestock grazed in the forest around the summer farm. The livestock affect their environment, and grazed forests generally contain a higher biodiversity than an ungrazed forest. The overall aim of this thesis is to understand the impact of livestock grazing on a northern forest ecosystem over a long time period.
Habitat preference and dispersal of a sandassociated beetle, Apalus bimaculatus
Species that have a high degree of specialization and poor dispersal ability can be more prone to extinction than more generalist species and good dispersers. How these species traits affect the viability of populations is dependent on landscape factors,such as isolation and connectivity. Additionally, interactions between species (e.g. symbiosis), and how these interactions vary spatially and temporally can have a large impact on populations. When the range and habitat areas of a species continuously decrease, management strategies are often needed if the species shall be able to survive.
Retention of stumps on wet ground at stump-harvest and its effects on saproxylic insects
Low stumps represent on their own up to 80% of the dead wood remaining on clear cuts and therefore supply suitable habitat for saproxylic insects i.e. insects depending on dead wood for their survival. Recent stump harvesting activities threaten this substrate of ecological importance and increase the anthropogenic negative impacts on these species. Because of technical and environmental reasons (nutrient leakage, erosion) guidelines for stump harvesting recommend to retain stumps standing in wet parts of clear cuts. However, stumps in wet positions might not be a satisfactory substrate for saproxylic insects and therefore might not be as much used as stumps in dry positions.
Varumärkesbyggande - konsten att skapa & bygga ett starkt varumärke för ett nystartat företag
This project is a collaboration with Ett Klick för Skogen, a foundation that buys and preserves endangered forests in Sweden. There are several ways of helping the foundation, e.g. buy a tree and for this the buyer obtains a symbolic diploma. Many organisations uses this method to collect money and for me the lack of a thorough expressions are consistent. The objective with this project has been to renew these diplomas for Ett Klick för Skogen and in the long run increase the collections and preservation of endangered forests in Sweden.The idea has been to vivify hardwood trees in a new and rather poetic than pedagogic manner.
Rörelsens betydelse för inlärningsprocessen.
The purpose of this examination was to se how exercise affects the learning capacity. In this work I have chosen to integrate natural science with sport and the target group was a primary department. The two areas I integrate with sports were: the digestive system and knowledge of deciduous trees. I split the class in two different groups. One group got to have a theoretical lesson and the other one got to have an exercise lesson.
Unga Bestånd - en tillgång i park- och landskap : woodlandkvarter från Alnarp till Jönköping
This is a thesis about design of young stands of trees. A big source of inspiration has been Västerskog and Tor Nitzelius Park in Alnarp which both consists of a structure of squares. I wanted to examine if this type of planting could be valuable from an aesthetic and recreational point of view. One problem today is that many people believe that we have to wait for decades for a planting to grow up so that we can enjoy the ?ready result?.
Mindre studie av en ny gallringsmetod i stamtät förstagallring av gran i södra Svergie
The main purpose of this study is to investigate how to reduce the high, and every decade raising, pre-clearance cost. The pre-clearance is today carried out with a brush saw and paid per labour hour. All small trees not suitable for pulpwood are removed to simplify the later work of the harvester.
The study compares the economic results from thinning of four parcels each treated differently regarding harsh or light pre-clearance and extraction of only pulpwood, or both pulpwood and fuel wood.
In this type of spruce stand the study indicates that a lighter pre-clearance, followed up with both pulpwood and a fuel wood extraction, has a much better economy than the traditional method of hard pre-clearance and only pulpwood extraction..
Sant eller falskt? : hur skildrar de nätbaserade media SANA, BBC och CNN händelserna mellan 1.4. och 18.4.2012 i Syrien?
This essay will try to analyze how Syria?s official news agency, SANA, describes events taking place in Syria in the days between 1.4 and 18.4.2012. This will be contrasted with how BBC and CNN describe the events. These other two news agencies were chosen, because they represent media from democratic countries in Europe and the USA. This rebellion became a full scale civil war over time.
Millesgården : vårdprogram samt förslag till förbättrad tillgänglighet
Millesgården is a museum on the island of Lidingö outside Stockholm. It contains the buildings which were the home and studios of the artist Carl Milles and his artist wife Olga. It also contains the grounds that originated as the garden of their home. Carl Milles later developed the garden into a sculpture park where a great part of the sculptors works are on display. In this report only the sculpture park is treated.

Möjligheter till uppfödning och utsättning av fasaner och gräsänder på Björnslunds gård :
This study treats the possibility of breeding mallards and pheasants on our own farm,
Björnslund. From the beginning I considered to breed them from eggs to adults but
after visiting several breeders I changed my mind. It seemed to be a lot of work with
no economic profit in comparison with buying already hatched birds and then feed
them to adults. If the business shall be profitable I have to be soll the hunting for the
birds and then sell the dead birds to game purchasers. There are also calculations that
show which price you have to charge for the hunting that will give a positive result.
Another possibility is to own a slaughterhouse and sell the meat to restaurants and
supermarkets.
