Long-term VHF radar (53 MHz with 3 beamwidth) observations at Gadanki (13.5 N, 79.2 E), India, during the period from September 1995 to August 1999 are used to study monthly, seasonal and annual medians of vertical eddy diffusivity, K in the troposphere, lower stratosphere and mesosphere. First, the spectral width contribution due to non-turbulent effects has been removed for further analysis a...

Soil respiration is a significant contributor to the global emissions of CO2 and governed by many soil factors. Reliable estimates emission on different scales (e.g., field, regional level) are hard obtain due expressed spatial temporal variability flux. This study aims investigate flux properties in soybean cropland Fluvisols (Croatia). The field measurements samples were taken regular samplin...

This paper presents an experimental characterization of liquid nitrogen (LN2) flow boiling in additively manufactured minichannels. There is a pressing need concerted efforts from the space exploration and thermal transport communities to design high-performance rocket engine cooling channels. A close observation literature gaps warrants systematic cryogenic asymmetrically heated small (<3 m...

This paper reports the improved rotor-film evaporator with lower arrangement of separating space, auger-type discharge concentrated organic fruit and berry paste, preheating puree secondary steam. The working surface is heated by a flexible film resistive electric heater radiating type an insulating outer surface. Peltier elements installed in device make it possible to provide low-voltage powe...

The PDF of N2O mixing ratio differences over various separation distances is studied using ER-2 airborne data. It is found that the PDF shape ranges from Gaussian, through stretched exponential and exponential, back to Gaussian as the separation distance increases from 200 m to about 200 km. With the PDF as a diagnostic tool, we identify the horizontal diffusive scale in the lower stratosphere ...

We propose a new model describing the production and the establishment of the stable gradient of the Bicoid protein along the antero-posterior axis of the embryo of Drosophila. In this model, we consider that bicoid mRNA diffuses along the antero-posterior axis of the embryo and the protein is produced in the ribosomes localized near the syncytial nuclei. Bicoid protein stays localized near the...
