The objective of the current research was to investigate effects of germination on chemical composition of hull-less barley (Hordeum vulgare L. var. nudum Hook. f.), hull-less oat (Avena sativa), rye (Secale spp.), and wheat (Triticum spp.) grains for comparison. All the grains were cleaned, washed, steeped and germinated at temperature 35 ± 2 °C and relative humidity 95 ± 2% for 12, 24, 36, and 48 hours. After germination grains were dried till moisture content 14 ± 2%. Main quality parameters such as starch, proteins, b-glucan (in hull-less barley) and individual sugars were determined in cereals during their steeping and germination. Non-germinated grains were used as a control sample. In the present experiments non-significant protein content increase was observed in the analysed hull-less barley, hull-less oat, rye, and wheat during their germination for 48 hours. Starch content in hull-less barley, wheat and rye grains decreased non-significantly during germination for 24 h; opposite results were obtained for hull-less oat grains, where content of starch decreased by 16.7% after steeping and by 26.4% after germination for 24 h. b-glucan content in hull-less barley grains after germination for 48 h decreased by 20.5%. Non-significant changes were obtained in fructose content in analysed cereal grains during germination for 48 h; it was significantly increased after germination for 24 h and in germination for 48 h. Non-significant sucrose content changes were observed in hull-less barley, rye and wheat grains during germination for 12 h and in hull-less oat grains – for 24 h significantly increasing in future germination for 48 h.

Late-life suicide is a significant public health concern that has been associated with a range of social and individual factors. Social factors, such as social isolation, lack of social support, and financial stress, regional differences can contribute to the risk of suicide in older adults. Individual factors, such as depression, anxiety, and other mental health disorders, as well as physical health problems and chronic pain, have also been associated with an increased risk of suicide in older adults. Understanding the social and individual factors that contribute to late-life suicide in both Latvia and Norway is essential for developing effective prevention and intervention strategies to address this issue. The novelty and aim of research on social and individual factors of suicide among older people lie in understanding the unique risk factors that contribute to late-life suicide both in urban and rural areas. While there is existing research on suicide in general, there are various factors that contribute to suicide risk in older adults. Regional differences are often different from those that affect younger populations. Therefore, research on social and individual factors of suicide among the older persons aims to identify these unique risk factors and develop tailored prevention and intervention strategies that address the needs of older adults. There is still a need for further research to understand the specific social and individual factors that contribute to this issue in rural and urban areas.
