Sulfuric Acid Decomposition

A thermochemical nuclear hydrogen producing process has been developed and evaluated from thermodynamics and engineering points of view. The cycle is based on sulfuric acid decomposition process developed earlier, which produces mechanical power using additional primary energy as well as excess process heat generated within the cycle. The sulfuric acid decomposition process has been closed using a sulfur dioxide electrochemical oxidizer cell and feasibility of its energy self-sufficient operation has been demonstrated. The first law efficiency of the cycle has been determined as 34.14 percent and the second law efficiency as 43.32 percent. It is found that the modified sulfuric acid decomposition section is improved by 14.8 percent compared to the basic process used in the sulfur family cycles. For a plant size producing 8.94 × 106 GJ H2 per year, the typical levelized costs of hydrogen are $20.15(1988) per GJ energy and $24.47(1988) per GJ exergy.

Airway Patency

The article presents a clinical case of successful treatment of a patient with prolonged asthmatic status. The pathogenesis of purulent-septic and other life-threatening complications developing as a result of the above critical condition is described. The positive effect of a differentiated approach in conducting respiratory support depending on the stage of the disease is justified: at the beginning, when airway obstruction is in the foreground, and in the future, when restrictive respiratory disorders develop. When conducting respiratory support, the most reasonable methods for ensuring airway patency were selected. The necessity of neurovegetative blockade and myoplegia for the prevention of pulmonary barotrauma during respiratory support by aggressive ventilation modes and with the goal of antihypoxic protection of the brain is emphasized. During the treatment of the patient, it was confirmed that the optimal regime for obstruction of the bronchi is forced volume-cyclic ventilation of the lungs to provide the necessary minute volume of breathing, and in severe pneumonia, in the case of relief of bronchial obstruction, respiratory support is carried out in pressure control mode for better air-oxygen mixture distribution in the airways. The need for early tracheostomy and daily therapeutic fibrobronchoscopy to ensure airway patency and treat pneumonia has been confirmed.
