Technical Notes on the Near Surface Experiments of Submerged Submarine
In this study, the experimental analysis on the bare hull resistance coefficient of submarine at snorkel depth is represented. The experiments are conducted in marine laboratory of Admiral Makarov University. The results are presented for surface condition and snorkel condition. Snorkel depth is regarded equal to one diameter of submarine hull beneath the water surface as usual in submarines. P...
متن کاملSurface crystallization of supercooled water in clouds.
The process by which liquid cloud droplets homogeneously crystallize into ice is still not well understood. The ice nucleation process based on the standard and classical theory of homogeneous freezing initiates within the interior volume of a cloud droplet. Current experimental data on homogeneous freezing rates of ice in droplets of supercooled water, both in air and emulsion oil samples, sho...
متن کاملPET/Mica nanocomposites for food packaging: crystallization behavior and mechanical properties
Nowadays polymer nanocomposites have introduced as a new class of food packaging materials due to their enhanced mechanical, thermal, and barrier properties. In this study PET nano composites were prepared by melt blending of poly (ethylene terephthalate) pellets and mica nanoparticles. The morphology of PET/mica nanocomposites was characterized by X-ray diffraction and transmission electron mi...
متن کاملHeterogeneous surface crystallization observed in undercooled water.
We report laboratory observations of higher freezing temperatures when an ice-forming nucleus is near the surface of an undercooled water drop than when the nucleus is immersed in the drop. The nucleation rate at the water surface is a factor of 10(10) greater than in bulk water, thereby complementing and providing evidence for homogeneous surface crystallization, which has been hypothesized re...
متن کاملEntropy and surface engineering in protein crystallization.
Protein crystallization remains a key limiting step in the characterization of the atomic structures of proteins and their complexes by X-ray diffraction methods. Current data indicate that standard screening procedures applied to soluble well folded prokaryotic proteins yield X-ray diffraction crystals with an approximately 20% success rate and for eukaryotic proteins this figure may be signif...
