Features of diagnosis and treatment of encysted pleural empyema
The incidence of non-specific pathological processes of the lung and pleura increases every year. Encysted empyema is leading in terms of morbidity and mortality among all the diseases of the lungs and pleura. Just empyema remains one of the biggest problems in diagnosis for doctors of primary and secondary levels of medical care. Up to this point there is no single diagnostic algorithm for the disease. And as a result we don‘t have the single algorithm of treatment of encysted pleural empyema
Classification of packaging for food and goods
Packaging is an integral part of food and goods.
Packaging provides safety products that comply with sanitary and aesthetic requirements, standards, ease of use and sales and promotes the competitiveness of products, protects the rights of producers and consumers in the market
Giant electrocaloric effect in thin film Pb Zr_0.95 Ti_0.05 O_3
An applied electric field can reversibly change the temperature of an
electrocaloric material under adiabatic conditions, and the effect is strongest
near phase transitions. This phenomenon has been largely ignored because only
small effects (0.003 K V^-1) have been seen in bulk samples such as
Pb0.99Nb0.02(Zr0.75Sn0.20Ti0.05)0.98O3 and there is no consensus on macroscopic
models. Here we demonstrate a giant electrocaloric effect (0.48 K V^-1) in 300
nm sol-gel PbZr0.95Ti0.05O3 films near the ferroelectric Curie temperature of
222oC. We also discuss a solid state device concept for electrical
refrigeration that has the capacity to outperform Peltier or magnetocaloric
coolers. Our results resolve the controversy surrounding macroscopic models of
the electrocaloric effect and may inspire ab initio calculations of
electrocaloric parameters and thus a targeted search for new materials.Comment: 5 pages, 4 figure
