Recently, it was realized that quantum discord can be seen as the minimal amount of correlations which are lost when some local operations performed. Based on this formulation discord, we provide a systematical analysis and classical present in both bipartite multipartite systems. As natural result analysis, introduce new measure overall is lower bounded by discord.

Bioaerosols are common biological factors in work environments, which require routine use of filtering respiratory protective devices (FRPDs). Currently, no studies link humidity changes the filter materials such devices, during use, with microorganism survivability. Our aim was to determine microclimate inside FRPDs, by simulating breathing, and evaluate survivability under varying conditions. Breathing simulated using commercial facepiece respirators a model system. Polypropylene...

To ensure that, a leak-tight fit facepiece user's face essential, regardless individual facial features.The objective this study was assess possibilities developing customized respirators well-fitting anthropometric dimensions using 3D scanning printing techniques evaluate custom-made device in terms protective, usage strength parameters.Commercially available...

Despite the awareness that work in sewage treatment plant is associated with biological hazards, they have not been fully recognised so far. The research aims to comprehensively evaluate microbiological and toxicological hazards air settled dust workstations a plant. number of microorganisms was determined using culture method diversity evaluated high-throughput sequencing. Endotoxin concentration assessed GC-MS (gas chromatography-mass spectrometry) while secondary metabolites LC-MS/MS...

The aim of this case study was the evaluation selected metals’ concentration, potential toxic compound identification, cytotoxicity analysis, estimation airborne dust biodiversity, and number microorganisms in environment (leachate, soil, air) biggest uncontrolled post-industrial landfills Poland. Based on results obtained, preliminary solutions for future management objects that have become an landfill were indicated. In air, PM1 fraction dominated, constituting 78.1–98.2% particulate...

This study aimed to assess the physicochemical, microbiological and toxicological hazards at an illegal landfill in central Poland. The research included analysis of airborne dust (laser photometer), number microorganisms air, soil leachate (culture method) microbial diversity environment (high-throughput sequencing on Illumina Miseq); cytotoxicity (PrestoBlue) genotoxicity (alkaline comet assay) were tested. Moreover, UHPLC-Q-ToF-UHRMS (ultra-high-performance liquid...

This study aimed to assess the markers of chemical and microbiological contamination air at sport centers (e.g., fitness center in Poland) including determination particulate matter, CO2, formaldehyde (DustTrak™ DRX Aerosol Monitor; Multi-functional Air Quality Detector), volatile organic compound (VOC) concentration (headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry), number microorganisms (culture methods), microbial biodiversity (high-throughput...

The aim of the present study was to evaluate relation between chemical (analysis elements and pH) microbiological composition (culture metagenomics analysis) dust at various workplaces (cement plant, composting poultry farm, cultivated area) cytotoxicity effect on human adenocarcinoma lung epithelial adherent cell line A-549 (MTT assay test).

Fall accidents in industrial and construction environments require an immediate reaction, to provide first aid. Shortening the time between fall relevant personnel being notified can significantly improve safety health of workers. Therefore, this work, IoT system for real-time detection is proposed, using ASSIST-IoT reference architecture. Empowered with a machine learning model, detect swiftly notify occupational manager. To train novel multimodal dataset was collected from ten human...

The counterintuitive effect of non-unique ordering two-qubit states with quantum entanglement measures was discovered over ten years ago. More precisely, it shown by Monte Carlo simulations that there exist for which the formation and negativity do not impose same states, i.e. $E_{F}(\rho_{AB}) \leq (\geq) E_{F}(\rho_{AB}^{\prime})$ is equivalent to $N(\rho_{AB}) N(\rho_{AB}^{\prime})$. Recently, discord geometric necessarily imply $X$-states, means lack unique goes beyond entanglement....
