The use of snus has increased markedly in Sweden in the past few decades, so much so that it now accounts for half of all tobacco consumption in the country. Over 20 per cent of men between the ages of 18 and 79 are daily users. Consumers of snus absorb as much nicotine as smokers but are spared many of the toxic chemicals that are formed on smoking.
Although snus does not seem to increase the risk of myocardial infarction, one of the studies reported on in this doctoral thesis shows that its consumers run a 30 per cent (approximately) higher risk of fatal heart attack than people who have never used the product. This greater risk is even higher for those who take more than 50 grams of snus a day. Amongst those who suffer non-fatal heart attacks, users of snus have a higher fatality rate in general than non-users, and from cardiovascular diseases in particular.
The studies reveal no greater risk of stroke amongst users of snus; however, users were more likely to suffer a fatal stroke. Users also ran a higher risk of developing high blood pressure, which is a known factor of cardiovascular disease.
Two major population studies were used for the research now published. The first comprised Swedish men between the ages of 45 and 70, living in the counties of Stockholm or Västernorrland between 1992 and 1994. A total of 1,432 men diagnosed with first-episode myocardial infarction were compared in terms of tobacco habits and other factors with a coeval group of men from the same regions without heart problems.
The second was a study using data from health checks of all workers in the building industry between the years of 1978 and 93. Information recorded at these checks included tobacco habits and blood pressure. Episodes of non-fatal and fatal myocardial infarction and stroke as well as blood pressure readings for over 100,000 snus users and non-users were then plotted up to 2003/4 using national health records.
In both population studies, the analyses were confined to non-smokers, as smoking is strongly associated with the use of snus and cardiovascular disease.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.
Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
