Let G be a finite group. We show that the order of the subgroup generated by coprime γk-commutators (respectively,δk- commutators) is bounded in terms of the size of the set of coprime γk-commutators (respectively, δk-commutators). This is in parallel with the classical theorem due to Turner-Smith that the words γk and δk are concise.

Different societies regulate differently. Historically, social evolution has often been connected to technological innovations. The combustion engine took a central position in what later became known as the industrialized society, an urbanizing era of factories and production, on its hand following on the rural society tied to agriculture and trade. With each type of society comes a specific type

Brain injury rehabilitation is a long and difficult process that includes training of so-called instrumental activities of daily living (IADL). This type of training involves activities like preparing meals, doing housework, grocery shopping etc. and it is often used by occupational therapists when they teach brain injury patients how to manage their daily life. A computer-generated Virtual Enviro

Mismatch negativity (MMN) is an EEG voltage fluctuation caused by the brain's automatic reaction to unexpected changes in a repetitive stimulation. In an experiment we studied 68 infants of which 2/3 were born preterm. Due to noise of large amplitude, the MMN is difficult to detect in a single infant's EEG. Therefore grand average, which is a average of many subjects EEG recordings, is sometimes u

The message conveyed by the Intergovernmental Panel on Climate Change (IPCC) is clear: the global climate crisis has arrived (e.g., IPCC, 2007, 2014). It is commonly understood that responding to this crisis requires coordinated actions at a global level (Weischer et al., 2012, p. 117; Kulovesi, 2012, p. 193). Attempts to slow down the increase in global temperature, as well as to organize and exc

The pressure on European air-traffic logistics increases, both at the airports and in the sky, as the passenger rate increases. Handling airborne aircraft is becoming more rationalized as an effect of sophisticated technology and lower separation-minima. Technological and legal development at airports is lagging behind causing delays. Airport operations might be more efficient by increasing accura

New anti-inflammatory drugs with fewer adverse effects than existing drugs may prove to be useful in the treatment of several inflammatory disorders. A critical step in acute inflammation is the infiltration of neutrophils into tissues. Therefore, molecules that target and inhibit this early inflammatory event are attractive to engineer to suit medical needs. The Chemotaxis Inhibitory Protein of

Packaging has great potential to contribute to sustainable development. This is due to its primary role to protect products. This paper reports on how Swedish consumers perceive and select food packages in general, and how environmental aspects of conventional and organic food packaging are perceived in particular. The study is based on a consumer survey. The findings indicate that contrary to res

This paper deals with CERTECs work to use haptics to provide a new way of using computers for visually impaired people and people with physical disabilities. We have chosen to call the concept The Phantasticon. CERTEC has developed a set of programs
