Essential aspects of the CFD software modelling of biomass gasification processes in downdraft reactors.

Mathematical modelling and simulation of gasification processes are increasingly used in the scientific field. This review explores the application of computational fluid dynamics (CFD) in modeling biomass gasification processes in downdraft gasifiers. It discusses the different types of gasification agents used, the composition of syngas, and key operational parameters influencing the process.

[Surgical Safety of Elderly Hospitalized Patients Stratified by Age in General Surgery].

Objective To compare the surgical safety of elderly hospitalized patients in different age groups undergoing general surgery,and provide references for preoperative evaluation and treatment decision-making.Methods The inpatients ≥ 60 years old in the department of general surgery were selected from a national multi-center survey conducted from January to June in 2015 and from January to June in 2016.The patient characteristics and postoperative outcomes were described,and the risk factors for adverse postoperative outcomes of patients in different age groups were explored.

Current status of pathway analysis in genome-wide association study.

Since the first publication in 2005, the genome-wide association study (GWAS) strategy has contributed significantly to the understanding of the mechanisms of human genetic diseases. Integrations of statistical methods and systematic biology are important means to explore the GWAS data. Pathway analysis establishes the importance of genetic variants from GWAS and provides insights into their biological significance.

Effect of a bolus dose of fentanyl on the ED₅₀ and ED₉₅ of sevoflurane in neonates.

Background: The minimum alveolar concentration (MAC) of sevoflurane in neonates is 3.3%, but this value has not been verified in Chinese neonates and the effect of different doses of fentanyl on MAC in neonates has not been investigated. This study was designed to determine the ED₅₀ and ED₉₅ values of sevoflurane in Chinese neonates with and without fentanyl.

Chlorido[1,1'-(5-methyl-1,3-phenyl-ene)bis-(3,5-dimethyl-1H-imidazol-2-yl-idene)]platinum(II).

In the title compound, [Pt(C17H19N4)Cl], the Pt(II) cation is C,C',C''-chelated by the 1,1'-(5-methyl-1,3-phenyl-ene)bis-(3,5-dimethyl-1H-imidazolyl-idene) anion and coordinated by a Cl(-) anion in a distorted square-planar coordination geometry. π-π stacking is observed between nearly parallel imidazole and benzene rings of adjacent mol-ecules, the centroid-centroid distance being 3.802 (4) Å.
