Flower Cues for Hawkmoths: Colour, Place and Odour

Popular Abstract in Swedish Blommor använder färg och doft för att locka till sig pollinatörer. Hur använder sig svärmare av dessa olika signaler för att hitta blomman? För att få svar på denna fråga undersöktes två arter av svärmare, en dagaktiv, Macroglossum stellatarum, och en nattaktiv, Deilephila elpenor. Båda arterna har färgseende och den nattaktiva svärmaren kan skilja på olika färger äveFlowers use different cues to attract pollinators including colour and odour. How do hawkmoths use these cues to find the flowers? This question was investigated in two species of hawkmoth, the diurnal species, Macroglossum stellatarum, and the nocturnal species, Deilephila elpenor. Both species have colour vision and D. elpenor can discriminate colours under very dim light intensities. Both speci

Combination of solar collectors and ground-source heat pump for small buildings

The combination of solar heat and ground-source heat pumps in dwellings gives opportunities for optimising the use of renewable energy sources and minimize the share of bought energy. Solar collectors in the system may give advantages for the operational conditions both for the solar collectors and for the heat pump. The aim of this project was to analyse different variables such as energy demand,

A beta-phosphoglucomutase in carbohydrate metabolism of Lactococcus lactis

Popular Abstract in Swedish Ett beta-fosfoglukomutas i kolhydrat-metabolismen hos Lactococcus lactisPhosphoglucomutase (PGM) catalyzes the reversible conversion of glucose 1-phosphate to glucose 6-phosphate. Two distinct forms of PGM have been purifed and charactierized in Lactococcus lactis growing on maltose: one specific for the alpha-isomer, and the other specific for the beta-isomer of glucose 1-phosphate. Beta-PGM was purified and polyclonal antisera to the enzyme were generated. Beta-PGM

Sven Nilsson och Skånes postglaciala fauna

Lundaprofessorn Sven Nilsson blev under 1800-talet internationellt känd inom så skilda ämnen som geologi, zoologi och arkeologi. Denna kontrasternas man, beskrivs som brilliant men temperamentsfull och snarstucken, med stort självhävdelsebehov, en svaghet för det sensationella men samtidigt mycket känslig för kritik. Hans faunahistoriska forskning var banbrytande och många av resultaten är aktuell

The book is a Finnish version of Terror och tystnad (2005).

Troublesome transformation. EU law on pregnancy and maternity turned into Swedish Law on parental leave

In 2006, a prohibition on less favourable treatment of workers related to parental leave was introduced in The Swedish Act on Parental Leave. The prohibition was designed on the basis of the rules on discrimination of pregnant workers and workers on maternity leave in the Equal Treatment directive. The Swedish rules do however separate from the EU rules in one crucial respect. While the European U

The Virtual Museum of the Western Han Dynasty: 3D Documentation and Interpretation

This project, aimed to the digital documentation of archaeological sites, artifacts and cultural relics of the Western Han Dynasty, started in 2008. The anticipated outcome will be the creation of a virtual museum, based on collaborative environments, dedicated to the Western Han Dynasty and able to integrate new archaeological datasets coming from fieldwork activities (most part of them unpublish

Throughput analysis of three multiuser diversity schemes

The throughput of three slot allocation schemes for the downlink of a wireless TDMA system are investigated under the assumption of block-Rayleigh fading. The schemes use the instantaneous SNR at the users in order to take advantage of the independent fading of the channels. In the first scheme, which has been proposed earlier (R. Knopp et al., 1995), the base station transmits to the user that ex

Integrated Product and Service Offerings Creates Logistical Challanges - The Problem and the Choice of Research Design

Yesterday’s sole hardware product is becoming more and more rare. Today, the original products are increasingly surrounded by value adding services, software or control systems, all bundled together to a “total offer”. Christopher (1998) states that it is the totality of the offer which delivers customer value, and that adding value through differentiation and/or service is a powerful means of ach

Combined linear-Viterbi equalizers - a comparative study and a minimax design

Combined linear-Viterbi equalizer (CLVE) is a term often used for a class of digital receivers reducing the complexity of the Viterbi detector by assuming an approximate channel model together with linear pre-equalization of the received data. The authors reconsider a weighted least squares design technique for CLVEs by introducing a minimax criterion for suppressing the strongest component of the

Eco-Standards, Product Labelling and Green Consumerism

This book provides the reader with a broad policy analysis of a main set of tools aimed at realising an increasingly appreciated aspect of late modern democracy: green political consumerism. The authors illustrate and explain how green labels and other eco-standards are created and negotiated within a broad continuum between science and politics, by addressing political, regulatory, discursive, an
