Some physical and mechanical properties of wood of Fast-growing tree species eucalyptus (Eucalyptus grandis) and radiata pine (Pinus radiata D.Don)

Received: February 2nd, 2021 ; Accepted: April 2nd, 2021 ; Published: April 16th, 2021 ; Correspondence: janis.iejavs@e–koks.lvFast-growing imported plantation tree species have become an available wood resource for Europe’s wood industry in the last decades. This sustainable alternative may reduce the gap between the increasing demand for and decreasing supply of the local tree species. The aim of the study was to determine and compare basic physical and mechanical properties of eucalyptus (Eucalyptus grandis) wood from Uruguay and radiata pine (Pinus radiata D.Don) wood from New Zealand as an alternative for Scots pine (Pinus sylvestris L.) from Latvia, to produce non– structural semi–finished glued laminated timber members for the manufacturing of windows. Such properties as density, swelling, bending strength, bending modulus of elasticity, compression strength and resistance to impact were determined according to ISO 13061 series standards test methods for small clear wood specimens. As the result of this study it was established that there is not significant difference between the majority of radiata pine and Scots pine properties, with the exception of resistance to impact and radial swelling where radiata pine shows significantly higher values. Not surprisingly all the properties of deciduous eucalyptus wood were significantly higher compared to both coniferous tree species. Higher swelling and density properties of eucalyptus compared to radiata pine and Scots pine should be taken into consideration for the design and production of wooden window elements

A System for Information Management in BioMedical Studies—SIMBioMS

Summary: SIMBioMS is a web-based open source software system for managing data and information in biomedical studies. It provides a solution for the collection, storage, management and retrieval of information about research subjects and biomedical samples, as well as experimental data obtained using a range of high-throughput technologies, including gene expression, genotyping, proteomics and metabonomics. The system can easily be customized and has proven to be successful in several large-scale multi-site collaborative projects. It is compatible with emerging functional genomics data standards and provides data import and export in accepted standard formats. Protocols for transferring data to durable archives at the European Bioinformatics Institute have been implemented

Risk indicators of elder mistreatment in the community

This study examined risk indicators of chronic verbal aggression, physical aggression, and financial mistreatment in a population-based sample of 1,797 independently living elderly in Amsterdam, The Netherlands. Included were socio-demographic characteristics, physical and psychological health, and functional capacity. The data were collected using standardized interviews that took place in the homes of the respondents. The results showed that chronic verbal aggression was associated with an elder living with a partner or other(s) and in poor or bad health. Physical aggression was associated with an elder living with a partner or other(s) and having depressive symptoms. Finally, financial mistreatment was associated with being male, living alone, being partially dependent in instrumental activities of daily living and having depressive symptoms. The results indicate that the risk indicators of victims of financial mistreatment differ from those of chronic verbal aggression and physical aggression, suggesting that financial mistreatment may occur more often as a single form of abuse whereas verbal and physical aggression may more frequently occur together
