Batch processes are very common and important in e.g. the chemical industries. The international standard ISA88.01 defines the terminology, the functionality and the models for batch control systems. The production specification of how to produce a batch, is called a recipe. This paper shows how high-Level Grafchart, a Grafcet and High-Level Petri net based programming language can be used to repr

The purpose of this paper is to give a description of the communicativity in a foreign language classroom and also of students’ communicative behaviour. Since the beginning of the 80s communication has been widely discussed as one of the main features in instructed language learning. The focus on form, that traditionally has been dominant in the language classroom, was combined or even replaced by

Studien undersöker Jean-Paul Sartres utvecklig från Varat och Intet (1943) – där den fria och ensamma människans relation till varat och den andre står i centrum – till den sociala och politiskt situerade människa som ringas in i Critique de la raison dialectique (Kritik av det dialektiska förnuftet, 1960). På vägen mellan dessa verk kommer den sartreska samtidshistoriens mest fundamentala konflik

With the assumed digitalisation happening on the end-user side, progressive security systems integrators stress the importance of changing the business concept from being installers to being service and solution providers. However, less is known about the details of this process on the end-user side, Markus Lahtinen of LUSAX project explains.

Both the EU and Sweden aim to incorporate hydrogen to decarbonize industries and reduce fossil fuel dependence. Liquid Wind, a company focused on sustainable electro-fuel production, develops facilities to convert biogenic CO2 and renewable hydrogen into green electro-fuel eMethanol. Such facilities, handling flammable substances, require quantitative risk assessments (QRA). Currently, Hydrogen QR

Att kunna skräddarsy biologiskt nedbrytbara stärkelsepartiklar för användning i medicintekniska produkter låter kanske som science fiction, men det håller snabbt på att bli verklighet! Dessa mikroskopiska partiklar tillverkar man av något som de flesta har hemma, potatisstärkelse och kan användas i medicintekniska produkter för att exempelvis blockera blodflödet till tumörer eller upptäcka läckageDegradable starch microspheres (DSMs) are promising biomaterials with expanding medical applications due to their biocompatibility and controlled degradation. DSMs are produced by forming a water-in-oil emulsion using a starch solution, an emulsifier e.g. Starch Acetate Butyrate (SAB) and toluene, followed by crosslinking using a crosslinker, e.g. epichlorohydrin (ECH). The relationship between re

This study examines members of parliament's perceptions of lobbying in Sweden and analyzes how these perceptions relate to the deliberative democratic ideal. The study is based on qualitative face-to-face interviews with eleven members of parliament from different parties and committees. The results show that the members of parliament have a complex view of lobbying, where they recognize both

Bosnia and Herzegovina has been one of the countries in the Western Balkans mostly affected by terrorism and the phenomenon of foreign terrorist fighters, which it has had a hard time combating. The country has been on the agenda of EU integration for many years, a process which has taken a very long time, but has in recent years accelerated rather drastically. There are many theories about terror
