Popular Abstract in Swedish Alla naturliga djur- eller växt- populationer varierar i tid och rum. Om man exempelvis räknar antalet individer av en viss art som befinner sig på ett visst ställe varje år, finner man att det antalet varierar från år till år. Varje år föds ett antal nya individer samtidigt som vissa dör (här bortser jag från de individer som eventuellt flyttar ut eller in). Antalet inAll natural populations fluctuate in space and time. These fluctuations are a result of internal dynamic processes, and of a variable environment. To understand how and why population fluctuate, one has to understand the nature of the internal demographic processes as well as how a variable environment affects these processes and how they act in concert to generate population fluctuations. This th

This paper reports on research on the engagement of ISO 14001 certified companies in environmental supply chain management, the drivers and barriers that influence their involvement, and how these forces correspond to the internal environmental management activities. In parallel, the issues of internal capabilities of companies, crucial for companies to respond to such driving forces, are highligh

In 1996, the Swedish electricity market was re-regulated and if private customers wanted to change their supplier they were forced to invest in a new electricity meter with hourly metering. The cost of such a device was typically around 900 EURO. Very few customers changed their supplier at this stage. On November 1st, 1999, this requirement was abolished and replaced with load profiling allowing

Popular Abstract in Swedish Utveckling av AMS-systemet i Lund för detektion av 26Al – med tillämpningar inom växtekologin Den konventionella metoden för att mäta mängden radioaktivt material i ett prov är att detektera strålningen som kommer från provet. Om man vet halveringstiden (den tid det tar för mängen radioaktivt material minska till hälften) så kan man bestämma antalet radioaktiva atomer Accelerator mass spectrometry (AMS) is a highly sensitive technique to count atoms. The method has a high efficiency, which makes it possible to measure small samples in a relatively short time, usually less than an hour. During the work for this thesis, methods have been developed to detect Al-26 at the Lund AMS facility. This includes the design, installation and testing of a new injector that i

This paper was prepared for a discussion of the concept of the schema, which is the fundamental pre-requisite for the presentation of experimental observations in natural language. On the basis of the schematism in language, the agent (knower) has been identified as the integrative component, which gives it the steering function in the behaviour on the visual cliff and the schematising processes a
