The Zvejnieki burial ground in northern Latvia is one of the largest concentrations of burials from the Mesolithic and Neolithic in Northern Europe. The 308 burials, dominated by primary inhumation, excavated in the 1960s and 1970s have become important references for understanding the hunter-gatherer mortuary practices in the region. Recent excavations, implementing a taphonomy-focused archaeotha

It was estimated that about 0.5% of the world’s population is in need of assistive devices; in 2013, the number of people who required such aid was estimated at 25 million in Africa and Asia. The majority of these people could have increased their participation within society by receiving an assistive device to facilitate mobilisation, recognised as a step in accessing basic human rights such as f

The physiological characteristics of native and bacterial exopolysaccharides (EPS) in oats and barley-based fermented products were studied in relation to the physico-chemical properties. Article I presents a parallel-randomized double blind clinical trial using a dairy-based product (control), an oat-based product (fermented with V2, which is a mixture (1:1) of Lactobacillus delbrueckii subsp. Bu

Increasing CO₂ emission is considered as the main reason for global warming in the world. One of the reasons for producing CO₂ is using of fossil-based materials in the construction projects. This study intends to assess the using bio-based materials instead of fossil-based materials for the thermal insulation layer of the external walls and roofs. Another focus of this project is using green conc

To this day, the question of what factors drive economic development and catching-up remains deeply controversial in growth literature. The concept of social capability provides a useful framework to investigate the relationship of the parallel processes of transformation, inclusion, autonomy and accountability with economic performance. Nevertheless, there are few attempts to quantify social capa

A search is conducted for non-resonant new phenomena in dielectron and dimuon final states, originating from either contact interactions or large extra spatial dimensions. The LHC 2012 proton-proton collision dataset recorded by the ATLAS detector is used, corresponding to 20 fb(-1) at root s = 8 TeV. The dilepton invariant mass spectrum is a discriminating variable in both searches, with the cont

What is already known about this subject Sagittal diameter (SAD), i.e. the mid height of the abdomen when lying down, has been reported to correlate to visceral fat, insulin resistance and cardiovascular risk factors in adults. SAD seems to be the best anthropometric predictor of cardiovascular risk, and also of more importance than waist circumference (WC) in adults. There has been no validation

Twenty-six plant species from the native flora used in Bolivian folk medicine were selected for studies of bioactivity. They belonged to the following families namely: Asteraceae (11), Brassicaceae (1), Cactaceae (1), Caesalpinaceae (2), Chenopodiaceae (1), Frankeniaceae (1), Geraniaceae (1), Laureaceae (1), Oxalidaceae (1), Piperaceae (1), Plantaginaceae (1), Rosaceae (1), Solanaceae (1) and Verb

The influence of different dryer fabrics on the contact coefficient has been studied experimentally under various conditions. A bench-scale drying apparatus, in which the fabric could be fixed at variable tensions, was used in the experiments. A technique for measuring the heat flux and surface temperatures of the paper sample and the hot surface was developed. Three paper grades were used in the

A novel calcium-independent serine protease from an alkaliphilic bacterium, Nesterenkonia sp. AL20, has been purified and crystallized at 296 K using sodium formate as the main precipitant. This enzyme is optimally active at pH 10, exhibits high stability towards autolytic digestion and its stability is not affected by the presence of EDTA or detergents. The triangular prism-shaped crystals diffra

The ribosome and tRNA levels of Escherichia coli cells, transformed with a native or mutated Vitreoscilla hemoglobin genes (vhb), were investigated using asymmetrical flow field-flow fractionation (AFFFF). Mutagenesis of vhb by error-prone PCR was carried out to alter the growth behavior of microaerobically cultivated native VHb-expressing E. coli. A VHb mutant, pVMT1, was identified, which was ab

Activation of the contact system has two classical consequences: initiation of the intrinsic pathway of coagulation, and cleavage of high molecular weight kininogen (HK) leading to the release of bradykinin, a potent proinflammatory peptide. In human plasma, activation of the contact system at the surface of significant bacterial pathogens was found to result in further HK processing and bacterial
