Evaluation of One- and Two-Box Models as Particle Exposure Prediction Tools at Industrial Scale
Toxics, 2021 One- and two-box models have been pointed out as useful tools for modelling indoor particle exposure. However, model performance still needs further testing if they are to be implemented as trustworthy tools for exposure assessment. The objective of this

Nordisk Museologi, 1970 Dust is a significant problem for museums – not only from the point of view of conservation, but also because it has a negative effect on the museum’s image. In this paper, I analyse the cultural connotations of museum dust: Why is dust in a museum so appalling, and, consequently, what do people really mean by the word pair dusty museum?

NEW METHOD OF GAS DRAINAGE AS A SOLUTION OF DANGER PHENOMENA IN UNDERGROUND COAL MINES
Rudarsko-geološko-naftni Zbornik, 2018 The further development of coal mining in different countries and in India is connected with many problems. Very serious are emission of gas, sudden outbursts of gas and coal, mine fires, dustiness, spontaneous combustion, methane concentration.

High Power Density, Low Temperature, Solid Oxide Fuel Cells at Elevated Oxygen Partial Pressure
Advanced Energy Materials, EarlyView.Elevated pO2${{p}_{{{{\mathrm{O}}}_2}}}$ improves oxygen reduction reaction (ORR) kinetics, thus reducing electrode area specific resistance (ASR). The effect of pO2${{p}_{{{{\mathrm{O}}}_2}}}$ in open circuit potential (OCP) and ASR is demonstrated on both Sr0.5Sm0.5CoO3‐δ‐Gd0.1Ce0.9O2‐δ (SSC‐GDC) composite cathodes and our recently developed nano‐PSC

Evaluation of different Starch Binders on physical quality of fish feed pellets
Brazilian Journal of Biology, 2022 Binders are the products that are used to bind, glue or hold the various feed ingredients together in order to maintain pellet integrity. For aqua-culturists, feed manufacturing is an expensive exercise due to the high cost of ingredients along with ...

Journal of the American Oil Chemists' Society, EarlyView.ABSTRACT In chocolate‐coated products, oil migration can lead to chocolate softening and discoloration, filling hardening, and reduced consumer acceptance. This study examined three fats (soy‐, palm‐, and palm‐kernel (PK) based), crystallized under different conditions (cooling rate and high intensity ultrasound (HIU)) with differing oil binding ...

Animal Research and One Health, EarlyView.Intensive or organic farming systems may expose pigs to management or environmental challenges. Our preliminary results concluded that organic farming might enhance adaptive immune function, showing that improvements in welfare can translate into measurable immunological benefits, based on the correlation between welfare assessment and physiological ...

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory
Astronomische Nachrichten, EarlyView.ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.
