Energy analysis and feasibility of using solar energy in the novel hybrid system of a solar hot plate dryer in Iran.

The drying process in agriculture is energy-intensive and traditionally relies on fossil fuels, which are becoming less reliable and more expensive. This study designed and simulated a hybrid solar hot plate dryer system using the computer to reduce reliance on fossil fuels. The system's main components are a flat plate collector, photovoltaic panels, and a wind turbine.

ALPK2 prevents cardiac diastolic dysfunction in heart failure with preserved ejection fraction.

Protein phosphorylation, controlled by protein kinases, is central to regulating various pathophysiological processes, including cardiac systolic function. The dysregulation of protein kinase activity plays a significant role in the pathogenesis of cardiac systolic dysfunction. While cardiac contraction mechanisms are well documented, the mechanisms underlying cardiac diastole remain elusive.

Bubble dynamics manipulation in polymeric foaming.

The release of pressure from a high-pressure-stable polymer/gas solution is a common method for creating gas bubbles and forming foam with a typical polyhedral cell structure. We propose a new approach to control the foaming process by pausing the bubble growth at intermediate pressure before reaching ambient pressure. This allows us to control the growth of the bubbles and investigate various physical phenomena involved in polymer foaming, such as Ostwald ripening, bubble interactions, coalescence, and different bubble growth regimes.

Super-Microsurgery for Vessels with Diameters Smaller Than 0.5 mm.

Among super-microsurgical techniques, the anastomosis of vessels smaller than 0.5 mm is very difficult to perform due to the small diameter and thinness of the blood and lymphatic vessel walls. In this article, we report on the main points of super microsurgery, particularly on the anastomosis of veins and lymphatic vessels with diameters smaller than 0.
