Influence of Supercritical Conditions on Isothermal Adsorption Capacity Calculation of Methane and Model Optimization.

The study of isothermal adsorption models for coal and methane under supercritical conditions helps us to understand the gas content distribution in coal seams and improve gas management in coal mines. Coal samples from the Hebi mine and Longshan coal mine were selected for this research. Using the weight method, isothermal adsorption curves of supercritical methane at temperatures of 308, 313, and 318 K were measured.

Preliminary investigation and application of a modified objects memory test in perioperative cognitive evaluation.

Objective: To investigate the applicability of a modified verbal learning test redesigned from the memory subtest of the Syndrom Kurztest (SKT) in perioperative cognitive evaluation.

Methods: Patients receiving elective herniorrhaphy and their accompanying family members (set as normal controls), 55-75 years old, were randomly divided into two groups. The two groups received the self-made objects memory test derived from the SKT (SMOT) SMOT or a traditional auditory verbal learning test (AVLT).

[Effects of positive end expiratory pressure on pulmonary surfactant in patients undergoing one-lung ventilation].

Objective: To evaluate the effect of positive end expiratory pressure on the bronchoalveolar lavage fluid (BALF) in pulmonary surfactant (PS) of patient during one lung ventilation anesthesia.

Methods: Patients undergoing Bullae resection were anesthetized with treatment (n = 12) or control (n = 12) combined anesthesia. Total phospholipid (TPL), saturated phosphatidylcholine (SatPC) and total protein (TP) in the bronchoalveolar lavage fluid (BALF) were measure.
