The Sami population living in Northern Finland represents a specific genetic background and a way of life that is different from other Finns. A cohort of 2,100 Sami and 4,174 non-Sami people from the 2 northernmost municipalities of Finland on 31 December 1978 was identified from the national Population Register and followed up through the Finnish Cancer Registry for cancer incidence during 1979 -1998. There were 111 cancer cases among the Sami, while the expected number based on the average cancer incidence in the Finnish population was 173. Among the non-Sami cohort members, there were 226 cases of cancer vs. 224 expected cases. The Sami had significantly decreased incidence of cancers of the prostate [standardised incidence ratio (SIR) 0.25; 95% confidence interval (CI) 0.08 -0.58] and breast (SIR 0.36; 95% CI 0.14 -0.73), similarly for both localised and nonlocalised tumours. Low SIRs were also observed for bladder cancer (SIR 0.28; 97% CI 0.03-0.99), basal cell carcinoma of the skin (SIR 0.12; 95% CI 0.03-0.30) and other nonmelanoma skin cancers (SIR 0; 95% CI 0 -0.63). In contrast to other subcategories of the Sami, the Skolts, whose lifestyle stems from areas that now belong to Russia, showed a nonreduced overall cancer risk and a significantly elevated risk for stomach cancer (SIR 3.8; 95% CI 1.5-7.8). The low cancer incidence among the other Sami populations in Finland cannot be fully explained by their specific way of life. It seems likely that the Sami ethnicity carries a reduced cancer incidence level. Although many Sami have been exposed to radioactive fallout from the nuclear weapon tests via their reindeer-rich diet, this does not seem to affect their cancer risk.

Sustainable work aims at improving working conditions to allow workers to effectively extend their working life. In this context, occupational safety and well-being are major concerns, especially in labor-intensive fields, such as construction-related work. Internet of Things and wearable sensors provide for unobtrusive technology that could enhance safety using human activity recognition techniques, and has the potential of improving work conditions and health. However, the research community lacks commonly used standard datasets that provide for realistic and variating activities from multiple users. In this article, our contributions are threefold. First, we present VTT-ConIoT, a new publicly available dataset for the evaluation of HAR from inertial sensors in professional construction settings. The dataset, which contains data from 13 users and 16 different activities, is collected from three different wearable sensor locations.Second, we provide a benchmark baseline for human activity recognition that shows a classification accuracy of up to 89% for a six class setup and up to 78% for a sixteen class more granular one. Finally, we show an analysis of the representativity and usefulness of the dataset by comparing it with data collected in a pilot study made in a real construction environment with real workers.

The effects of age of growing turkeys and beta-glucanase-xylanase activity-containing feed enzyme supplementation on digestibility and feeding value of pelleted maize, wheat, barley and oats were investigated in growing turkeys using excreta collection and ileal sampling by slaughter. Excreta were collected and turkeys were slaughtered at 4, 8 and 12 weeks of age. Viscosity of jejuno-duodenal digesta, caecal volatile fatty acid concentration, ileal crude protein digestibility, total tract fat digestibility and AMEN were assayed using titanium dioxide as an indigestible marker. The highest viscosities were observed in barley and wheat. Viscosity of wheat, barley and oats digesta decreased while caecal volatile fatty acid concentration, fat digestibility and AMEN increased with age. Ileal crude protein digestibility was highest in wheat and lowest in barley. Ileal crude protein digestibility significantly declined with age in most feeding treatments. Enzyme reduced digesta viscosity most efficiently in wheat and barley and improved ileal crude protein digestibility, total tract fat digestibility and AMEN in wheat, barley and oats, but interactions occurred, the effect of enzyme on viscosity being the most remarkable for wheat and barley and for the young birds.

Video management research has largely been ignoring the increased attractiveness of using camera-equipped mobile phones for the production of short home video clips, mostly considering them as additional channels for video consumption. The CANDELA project, which is part of the European ITEA program, focuses on the integration of video content analysis with advanced retrieval, mobile, networked delivery, and distributed storage technologies. In this paper, we present the CANDELA personal mobile multimedia management platform, which implements an end-to-end system for personal video production, retrieval, and consumption utilizing mobile devices and distributed databases.
