BackgroundModern data generation techniques used in distributed systems biology research projects often create datasets of enormous size and diversity. We argue that in order to overcome the challenge of managing those large quantitative datasets and maximise the biological information extracted from them, a sound information system is required. Ease of integration with data analysis pipelines and other computational tools is a key requirement for it.ResultsWe have developed openBIS, an open source software framework for constructing user-friendly, scalable and powerful information systems for data and metadata acquired in biological experiments. openBIS enables users to collect, integrate, share, publish data and to connect to data processing pipelines. This framework can be extended and has been customized for different data types acquired by a range of technologies.ConclusionsopenBIS is currently being used by several SystemsX.ch and EU projects applying mass spectrometric measurements of metabolites and proteins, High Content Screening, or Next Generation Sequencing technologies. The attributes that make it interesting to a large research community involved in systems biology projects include versatility, simplicity in deployment, scalability to very large data, flexibility to handle any biological data type and extensibility to the needs of any research domain.
The paper presents the results of research on the reduction of mechanical interactions of the composite produced from components resulting from the recycling of used car tires and plastic bottles (i.e. polyethylene terephthalate, colloquially called PET). Composite samples for testing were made with three thicknesses of mixtures rubber granules and PET flakes. The whole was joined together with an epoxy resin and formed into the shape of discs, which were then subjected to mechanical interactions to determine the damping properties depending on the thickness of the considered samples. The samples were subjected to evaluation on the author’s measuring stand. Obtained results of the research indicated that the developed composite well suppresses mechanical interactions resulting from dynamic interactions involving vibrations or vibrations in the analyzed frequency range. The developed composite can be used as a contribution to use in building materials that reduce mechanical interactions.
Worn out car tires and plastic from food wrappings constitute a problematic waste. They pollute the environment and management of such waste is important both ecologically and economically as it protects the environment, and reduces the costs of acquiring components to produce different materials. In this article, the results of testing modified concrete are shown. The concrete was modified with a mixture of supplements in the form of the pre-mentioned materials. The car tires provided, upon processing, rubber granules SBR of the following fractions: 0÷1 mm, 0.8÷2 mm, 2÷4 mm. Plastics of polyethylene terephthalate were used in the form of PET flakes. Six concrete series were generated where 10% of the cement mass was replaced with the supplement mixture. Tests of the texture and compression strength of a modified concrete mixture were conducted after 7, 14, and 28 days. All the series of concrete shared satisfactory homogeneousness of decomposition in the particular components. The strength tests proved that the application of rubber granules SBR and PET flakes in the form of a supplement mixture obtains a concrete strength of about 40 MPa.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
