Högeffektslysdioder. Möjligheter och förutsättningar för högeffektslysdioder som belysningskälla - ett demonstrationsbygge

This report examines the prerequisites for LEDs to replace other technologies indifferent applications. How does the different technologies for light generationwork and what are the advantages and disadvantages? The various technologieslimitations and characteristics provides the opportunities for the LEDs.This report describes a test-construction built to examine what practical arrangementscan be built with modern light emitting diodes, in order to showsome of the possibilities. The construction consists of three different applications,a high power lamp based on cold white LEDs, one based on warm whiteLEDs for the evaluation of the light characteristics and a RGB-LED based lampable to mix any colors quickly and seamlessly. The test construction also containsthe essential peripherals including control-electronics, optics and a custombuilt watercooling solution.The potential for LEDs is huge but it is complicated to build LED based applicationsdue to the limitations which mainly includes the electronics and theneccesary cooling.

Does tree removal along railroads in Sweden influence the risk of train accidents with moose and roe deer?

After the storm Gudrun in 2005, the Swedish Transport Administration started clear-cutting of railroad corridors to reduce the risk of trees falling down on the tracks. Simultaneously, train accidents with moose and roe deer have become more frequent and the costs for consequent delays and repairs of engines are of growing concern. There is reason to assume that tree-clearance of railroad corridors may have contributed to an increase in number of accidents with moose and roe deer because the cleared areas provide attractive forage and thus may attract wildlife. The objective of my study was to investigate how clearing of trees affected the number of accidents with moose and roe deer. I compared deer-train collision frequencies before and after clearance of the selected railroads and compared these with uncleared control railroads in a BACI (before-after control-impact) approach.

Teknikimplementering vid muddringsprojekt : Viktiga faktorer vid teknikval samt olika aktörers betydelse i processen

There are today large amounts of contaminated sediments in the Baltic Sea. These contaminants are the result of many years industrial activity where the contaminants have not been taken care of and just released out in the water. When ports want to dredge in their fairways and harbor areas the contaminated sediments need to be considered since they are a environmental risk. The development in this area has been slow and new techniques have just recently made its way into dredging operations in the Baltic Sea region. As a result of this there are no clear methods for implementing new techniques today.

Forming teacher teams is currently the standard way of organizing teachers in Swedish Compulsory Schools. This is the result of a process that started in the 1970s.Traditionally the culture of teaching has been one of isolation. Once the door to the classroom is shut, what happens behind the door is up to the teacher to decide. Over the past thirty years a lot of time has been dedicated to making fundamental changes in the way teachers interact with their colleagues. Today the idea of teachers forming teams is generally accepted but still the core of a Swedish teacher?s job is that of a lone worker.

Inkludering kontra utanförskap inom Idrott & hälsa :  En kvalitativ studie gällande hur elever med funktionsnedsättning upplever ämnet

The subject-matter of the following essay is to investigate the relationship between what is commonly called Deep Ecology or Biocentric Philosophy, as articulated by the co-founder of the Deep Ecology Movement, Arne Naess, and later proponents of the biocentric school of environmentalist thought. I contrast Naess? concept of Self-realization as founded in his Ecosophy T to the ideas of american conservationist and co-founder of the radical green movement Earth First! Dave Foreman, and to the controversial finnish environmentalist and ecofascist Pentti Linkola?s ideological agenda of population-reduction respectively.According to some critics of the movement, especially the social ecologist Murray Bookchin and French liberal philosopher Luc Ferry, the Deep Ecology ideology is essentially misanthropic and totalitarian in structure. A central idea among deep ecologists is that ecosystems and natural entities have intrinsic value in themselves, even outside a human social context. This idea is thought of among deep ecologists to create a philosophically sound basis for counteracting the environmental global crisis.
