Nätfilter är en lösning som i bästa fall är overksam och i sämsta fall direkt kontraproduktiv. Resultatet riskerar i stället bli att ungas aktiva nyfikenhet resulterar i skuld, skam och tystnad.

Dielectric response in insulators: A wave-vector- and frequency-dependent model

We have calculated a random-phase-approximation-type expression for the dielectric response function of several large-band-gap insulators using a development of the model suggested by Fry. This model should be good for systems with well-localized valence-electron functions and flat valence-electron bands. We show that in this model it is a minor approximation to use spherically symmetric bands in

Enzymatic Synthesis of Alkyl Glycosides. New Applications for Glycoside Hydrolases

The environmental problems caused by human interventions, such as the consumption of non-renewable resources and the emission of greenhouse gases are well-recognised. Calls have been made for immediate measures to develop more sustainable society worldwide. Attention has also been devoted to the quest for sustainability within the field of chemistry. The concept of “green chemistry” is being intro

A GALS ASIC implementation from a CAL dataflow description

This paper presents low power hardware generation, based on a CAL actor language dataflow implementation. The CAL language gives a higher level of abstraction and generate both hardware and software description. The original CAL flow is targeted for hardware-software co-design of complex systems on FPGA. Modifications are done to the original CAL flow to facilitate low power ASIC implementations.
