Föryngring av tall med och utan skärm på Gotland / Regeneration of Scots pine with and without shelter wood on Gotland

Hammarberg, Sarah January 2014 (has links)
Föryngringen av skog på Gotland har historiskt sett varit problematisk under lång tid och i dagsläget används främst markberedning följt av plantering av tall. Förutsättningen för föryngring under skärm samt naturlig föryngring under fröträd som föryngringsmetod har studerats i denna rapport då det råder brist på skriftliga sammanfattningar om dessa båda metoder. Föryngringsmetoderna studerades genom fältstudier på 16 lokaler och intervjuer med verksamma inom branschen på Gotland. Naturlig föryngring visade sig ha viss framgång på norra Gotland samt fungera väl på nordöstra Fårö. Förutom på Fårö visade emellertid föryngring med markberedning och plantering bäst resultat. Plantering under skärm och självföryngring under skärm verkade fungera på norra Gotland på jordar av grus och sand. Att resultatet skiljer sig åt beror sannolikt på olika markstrukturer för de olika delarna av ön där vissa av norra Gotlands jordar med sand, grus och mindre stenstruktur har större nytta av en högskärm samt lämpar sig bättre för naturlig föryngring.

A Study On Tall Buildings And Aerodynamic Modifications Against Wind Excitation

Ilgin, Huseyin Emre 01 February 2006 (has links) (PDF)
The purpose of this thesis is to create basic design guidance for tall buildings and their aerodynamic modifications as a resource for architects, engineers, developers, and students. It aims to make a contribution to and strengthen particularly the architect&amp / #8217 / s understanding of tall building design, that requires a high level of interdisciplinary approach, by providing a broad overview of the tall building with its general concepts / to demonstrate the importance of human element as a critical component in the design of tall building by clarifying the wind forces and resulting movements which cause discomfort to building occupants and create serious serviceability issues / and to show the significance of aerodynamic modifications as an effective design approach in terms of mitigating wind excitation. In order to achieve these purposes, firstly, a comprehensive literature survey, which includes the definition, emergence and historical background, basic planning and design parameters, and lateral load considerations of tall buildings is presented. Following a structural classification of the tall buildings, wind excitation, its negative effects on occupant comfort and serviceabilty issues, and the methods to control wind excitation are studied. Finally, the significance of aerodynamic modifications against wind excitation, which include modifications of building&amp / #8217 / s cross-sectional shape and its corner geometry, sculptured building tops, horizontal and vertical openings through-building, are presented from the scholarship on this topic.

Gamla tallars betydelse för biologisk mångfald på Gotland

Lars, Enström January 2009 (has links)
Modern methods for managing pine (Pinus sylvestris) create homogenized forests. This decreases nature’s potential for biodiversity and might threaten species in need of different types of milieu. The main purpose of this study was to investigate how important older pine trees are for biodiversity. In the Hall-Hangvar Reserve in the north-west part of Gotland, insects collected from traps showed that more species were found in old or dead trees compared to younger pine trees. A statistically significant difference was found for Coleoptera (beetles). The taxons of greatest interest for this study were Coleoptera and Hymenoptera (wasps). Certain families of Hymenoptera use ducts made by larvae from some families of Coleoptera.These larvae also serve as prey. Relevance concerning enviromental importance to species and diffrenences in inhabiting the three stages of pine trees was of importance.
