Skiktning och strukturell utveckling i unga naturlika skogsplanteringar: :
Multilayered woodland types are an important part of the urban forest. The knowledge how to establish and maintain such plantations are not as deep as other knowledge fields concerning forestry. Therefore this study has looked upon how to achieve multilayered structures in young nature-like woodland plantations. As a theoretical base for the study three different major knowledge culture have been studied that concerns the subject, ecology, forestry and landscape management/design. This three theoretical framework concludes that many natural processes strive in the opposite direction of multilayered structures in their youth.
Tree species traits response to different canopy cover for 34 tree species in an enrichment planted tropical secondary rain forest in Sabah, Malaysia
Tropical rain forests only cover around six percent of the world?s land area and contain around 70 % of the world´s animals and plants. Tropical rainforests have been, and still are, negatively affected by human activities. These activities lead to forest degradation which has negative impacts on production and biodiversity.
Between 1970-1980 forests in Borneo, Sabah, Malaysia, was subjected to intense logging.
Rehabilitation in a tropical secondary rain forest in Malaysian Borneo : early effects of canopy properties on light conditions at the forest floor
Tropisk regnskog i Sydostasien är ett av de områden som hyser störst biodiversitet i världen, av vilken stora ytor är hotat. Ön Borneo drabbades av en katastrof åren 1982-1983 efter att väderfenomenet El Niño orsakat torka med vidsträckta skogsbränder som följd. Detta lämnade stora ytor av Borneos skogar i ett undermåligt, sekundärt tillstånd. På grund av detta startades INIKEA projektet med syfte att rehabilitera skogar i regionen kring Tawau vid östkusten av delstaten Sabah i Malaysia. I denna studie undersökte jag resultatet av rehabiliteringsarbetet på krontaket i tre olika skogstyper genom att ta hemisfäriska foton med en digital systemkamera (DSLR).
"Nu rasar diktaturerna!" : Samhällskritiken i Per Wahlöös journalistik
Per Wahlöö is one of Swedens most internationally renowned authors with the crime novels about Martin Beck as the Crown jewel. His career as a journalist is not that famous. The cardinal question in this paper therefore is whether the social criticism that made his authorship so famous emanates from the journalism he produced before or simultaniously with his work as a novelist. To do so I have used a text analytical method on all of Per Wahlöös journalistic writings between the years 1947 and 1965. The sources have consisted of both daily newspapers, most notably Kvällsposten, and weekly magazines like Veckorevyn and Folket i Bild.
Naturreservat : en bra naturvårdsåtgärd för att bevara enskilda arter och/eller bevara den biologiska mångfalden?
The examination of the adequate nature conservation methods in a natural reserve, to conserve a specific species and / or increase biological diversity is the subject of this study. This work is based on four species, that can be found during the Spring season, liverleaf, wood anemone, brimstone and woodpecker. The incidence and availability is studied and closely observed for these species in twenty forests, i.e. ten forests which are nature reserves and ten forests with the similar characteristics as the nature reserves habitat, but are not nature reserves in Gnesta mucipality, Södermanland. Measurements of the tree Crown and the diameter of the tree trunks where noted to study how these factors could affect the outcome of the abundance and incidence of the four species.
1100-talets borgar i Skåne. En analys över den första medeltida borgbyggnadsfasen i Skåne
This essay is an attempt in analysing the establishment of the first Early Middle Ages castles in Scania. There are two types of castles in Scania during the eleventh century, keeps andringworks. This castle was built by three fixed elements of power: the Crown, the church and the aristocracy. The result of the survey shows that A majority of the castles during theeleventh century in Scania where initiated by the church.The results also show two building phases of castles under the period. The first building phase begins in middle of the eleventh century and the second building phase begins in theperiod 1180- 1200.
FORL : Feline Odontoclastic Resorptive Lesions
This report was written in an attempt to summarize old and new theories and scientific
results regarding FORL (Feline Odontoclastic Resorptive Lesions). Several different kinds
of treatment are presented in this study. Among them teeth extraction and Crown
amputation seems to give the best long-term results. It seems clear that the domestic cat of today have no trouble digesting dry foods without their teeth. The most accurate way to diagnose FORL is by using intraoral dental radiology technique.
Brasil um pais para todos-en studie av MST:s tillvägagångssätt och mobiliseringsstrategi
AbstractThe struggle for land has been an issue ever since Brazil was colonized by the Portuguese Crown. The deep social inequalities that the country faces were raised then. More than 45% of the agricultural land is controlled by only 1% of the landowners. There have been many movements since then, who has fought for agrarian reforms.MST, the largest social movement in Brazil, was born in the 1980s. They managed to mobilize the peasants and the poor people.
Kärlek som statsangelägenhet : En kvantitativ undersökning av tidningsartiklar publicerade under det kungliga bröllopet 2010
2010 was the year of the wedding between Sweden?s Crown princess Victoria and Daniel Westling. Although the wedding was partly financed with tax payer?s money, the newspapers did not investigate it further. The main theme of the published articles was lighter and with an entertainment value rather than finding out what the tax money really went.
Optimerande av gasanläggning - genom värmeåtervinning och förlustreducering. Gässlösa Reningsverk
The municipality, of Gatukontoret in Local government of Borås has in the long run, a required need to look after the current heating devices (the gas production plant) in sewage treatment plant, called Gässlösa. The practical work of the examination is about, trying to find a better way to take care of the current heat recovery. That may be one way or another, rather easy to implement in the existent construction.Through the work to increase the efficiency of the gas engine, implement of some external cooling system by heating exchange device. That gives an opportunity to heat (primary) the digester, (but even all internal public areas) with its own superfluous heating.The report shows that if the management group may invest 422 704 Crown to implement a heat exchanging device, it gives more space to reduce the need to buy expensive external energy. Gatukontoret´s pay off time, for buying machines, is 20 years, with reservation to calculate with 4 percent internal interest, leads to the yearly mount of 31103 Crowns.If Gässlösa increases the gas engine time in (effective) duty approximately (correspondingly) 48 hours a month the entire investment will generate a profit in January in year seven after the implementations.
Skötselns och ståndortens betydelse för kärnvedsbildningen i tall
Heartwood has always been a desirable part of the tree, due to it?s superior decay qualities com-pared to the sapwood. How the formation of heartwood works has been known for a long time, but which factors that initiates and stimulates the production are poorly understood. This case study presents the results of a study in which silvicultural treatments and site properties had a key position as factors to the formation of heartwood. According to the hypothesis the amount of sapwood is directly controlled by the size of the Crown.
Utvärderande bibliometri: en jämförelse mellan två kvalitetsindikatorer
This master's thesis aims to explore the field of evaluative bibliometrics. In short, this field of research uses bibliometrics - i.e. the application of mathematical and statistical methods to books and other media of communication - as a research assessment tool. In recent years, evaluative bibliometrics has been an increasingly used method in research evaluation and is today used and implemented in many countries worldwide. Today, in Sweden, we can also see that evaluative bibliometrics is highly recognised and, in some cases, used in practice.
Ett svenskt kronvittnessystem? Att vara eller inte vara ett kronvittne
Kronvittnessystem har vid ett flertal tillfällen diskuterats i svensk politik som en möjlig åtgärd i arbetet mot organiserad brottslighet. Ett kronvittne är en person som vittnar om sin egen eller andras brottslighet och på grund av detta erhåller ett mildare straff för sina brott. Flera andra länder använder sig av kronvittnessystem på grund av de nyttor som finns med det, men forskning visar att det även finns problem med systemet. Syftet med denna studie är att besvara frågan vad kriminella personer har för uppfattning om att kronvittna i ett kronvittnessystem. Kvalitativa intervjuer genomfördes med före detta kriminella med erfarenhet av organiserad brottslighet.
Planteringsförbandets inverkan på bestånd av contortatall (Pinus contorta var. latifolia) med avseende på volymtillväxt och virkesegenskaper
At the beginning of the 1970´s forestry feared an imbalance in the future wood supply. Because of this anticipated "timber slump" forest companies undertook a variety of measures to counter this. One of these measures was the introduction of exotic tree species. The choice finally ended up with lodgepole pines which were considered a fast growing tree species compared to our native tree species. Theambition for the new lodgepole pine stands were to run these with rotation periods of between 40-60 years, thus smoothing out the ?timber slump? that was anticipated.
Flygburen laserskanning kopplat till skördarmätning för datainsamling till operativ planering :
The requirements for operative planning activities are increasing. The forest industry wants to gain better control over wood flow. A felling that is more market adjusted is desirable. However, this causes problems in the operative planning process because of the data collection methods used today. Data about timber assortments and data about the distribution of the tree diameter, etc., are often lacking.
Airborne laser scanning is used to a greater extent than before for estimation of forest variables and should perhaps be used to the same extent in operative planning activities as well.
