The assessment of forest soil respiration and its isotopic composition is one of the important issues for the carbon cycling modeling (greenhouse gas emission control) because it is often inaccurate. Soil respiration is a complex process, depending on the coupling of several phenomena, which is therefore highly sensitive to any disturbance. In this work, the dynamics of the transport of two ...

Designing and constructing a lab-on-a-chip device poses a variety of questions. Transport of all required substances, detection of the analyte and its deposition on a sensor have to be incorporated. Different strategies have been developed to achieve good coverages of the sensor, like employing electric or magnetic gradients. On the basis of a ramp like structure, the binding of the analyte to a ...

Bread is a food product which various complex physico-chemical phenomena occur during the cooking process. Thus, phenomena of heat and mass transfer are coupled to the deformation. In addition, bread is a multiphase product (solid, liquid and vapor) and composed of various components (dry matter, water, air and carbon dioxide). A 2D model is developed with COMSOL Multiphysics® 4.3b witch ...

A neutrino oscillation experiment aims to the observation of the transformation of a neutrino of a given flavour into a neutrino of a different flavour. A beam of neutrinos is produced through the decay of charged pions which in turn are produced in the collision of high energy accelerated protons impinging on a thick target. A series of magnetic horns is used to focus charged particles produced ...

When a wineglass is touched with a wet finger along its edge, it vibrates at single frequency and you hear a clear sound. If the water is added into the glass, the sound pitch changes because the resonance frequency changes with the mass of the glass. When there are plural glasses with different quantity of the water, it becomes the musical instrument called the glass harp. Although the glass ...

This paper presents the numerical simulation model for radiocesium leaching and transporting behavior in municipal solid waste (MSW) landfill and discusses on the design for the required geometry and properties of the impermeable final cover and the soil sorption layer, which work for containment of hazardous waste such as radiocesium-contaminated MSW generated by Fukushima Daiichi nuclear ...

Uterine contractions during pregnancy are currently poorly understood – experts disagree on the mechanisms by which contractions propagate through the organ and the structural layout of the uterine muscle fibers. We have developed a multi-scale model of the uterus, at the cellular, tissue, and organ levels. By comparing simulated abdomen-level magnetic field readings from our model to clinical ...

Turgor pressure loss and pectin degradation result in texture loss during cooking of plant based materials. To simulate texture loss, a simultaneous heat and moisture transfer, pectin degradation in the cell wall material and solid mechanical model was developed at the microscale using finite elements to predict the homogenized Young’s Modulus of the carrot tissue during heating. The model ...

Predictive simulations of biomass conversion processes will improve their technical performance and reduce economic uncertainty surrounding industrialization of biofuels production. The majority of present conversion simulations treat the biomass feedstock with simplifying assumptions that neglect important characteristics that are unique to biomass particles. These characteristics, including ...
