The physics of moisture transfer is complex and as a result modelling is normally carried out on a macroscopic basis, with empirical coefficients used to simulate the transport process. These coefficients are not single values but depend on the moisture content of the material. The application of this data within the simulation environment requires the determination of a systematic methodology ...

Reduction in the moisture content of the medium produced a profound effect on the colony morphology of Campylobacter fetus subsp. jejuni. Fresh medium produced flat, grayfish, spreading colonies with an irregular shape and variety appearance. Plates that were incubated at 30 degrees C for 48 h produced round, convex, butyrous colonies with an entire edge. Plates incubated at 30 degrees C for 24...

Perovskite solar cells have shown unprecedent performance increase up to 22% efficiency. However, their photovoltaic performance has shown fast deterioration under light illumination in the presence of humid air even with encapulation. The stability of perovskite materials has been unsolved and its mechanism has been elusive. Here we uncover a mechanism for irreversible degradation of perovskit...

We aimed to introduce and test the "seed mass-distribution range trade-off" hypothesis, that is, that range size is negatively related to seed mass due to the generally better dispersal ability of smaller seeds. Studying the effects of environmental factors on the seed mass and range size of species, we also aimed to identify habitats where species may be at risk and need extra conservation eff...

Bio fuel plays an important role in the energy production of the forest industry. The initial moisture of the fuel typically varies between 50 63 w-%. A multi stage drying concept has been developed for the drying of wet bio fuel. To adjust the temperature levels in the multi stage drying system there must be a simple and fast method to define the fuel initial moisture. A method to define the i...

Real-time non-invasive moisture content sensing techniques are needed for online moisture measurement and control in food products. In this investigation, a dielectric spectroscopy based system is used for moisture determination in cookie dough. Experiments were conducted with a concentric ring dielectric sensor in the frequency range from 10 Hz to 10 kHz. The system is calibrated based on a li...

The push for lead-free or RoHS-compliant products is resulting in significant changes in packaging materials. Manufacturers of electronic equipment require materials that consistently withstand peak reflow temperatures of 240°C to 260°C. Reflow soldering at these extreme temperatures, especially after extended moisture exposure, introduces several challenges that must be solved to produce relia...

New data on clouds and moisture, made possible by reanalysis of weather satellite observations, show that the atmosphere reacts to warm ocean pools in the Western Pacific Ocean with increased moisture and cloudiness~ suggesting a negative feedback limiting the rise in seasurface temperature. The reverse was observed over hot deserts where both moisture and cloudiness decrease, suggesting a posi...

UNLABELLED BACKGROUND AND AIMS The negative logarithmic relationship between orthodox seed longevity and moisture content in hermetic storage is subject to a low-moisture-content limit (m(c)), but is m(c) affected by temperature? METHODS Red clover (Trifolium pratense) and alfalfa (Medicago sativa) seeds were stored hermetically at 12 moisture contents (2-15 %) and five temperatures (-20, 30,...

Wound bed preparation is a new approach that integrates proven concepts to build a platform for the treatment of chronic wounds. It organizes currently approved medical procedures and products into a holistic approach that can be used to evaluate and remove barriers to the wound-healing process. Removal of such barriers allows for optimal wound repair and healing. To address these barriers, a s...
