BACKGROUND We report a case of Ex-PRESS miniature glaucoma shunt obstruction resulting from progressive iris synechial formation after transient anterior chamber shallowing. CASE PRESENTATION A 68-year-old woman with pseudoexfoliation glaucoma in her right eye underwent filtration surgery with implantation of the Ex-PPESS shunt (model P-50, Alcon Japan, Tokyo, Japan) in combination with intra...

The spontaneous combustion of residual coal in the gob seriously threatens safety mining. Injecting CO 2 into not only prevents from but also realizes storage mined areas. Injection flux and burial depth port are crucial for -preventing fire mine gobs. In this study, distribution oxidation zone Tanyaoping was field-measured, kinetic model built by adiabatic test. Then, a 3-D mathematical constr...

Hydrogen is considered to be a suitable supplementary fuel for Spark Ignition (SI) engines. The energy and exergy analysis of engines important provide theoretical fundaments the improvement efficiency. However, few studies on balance engine working under Direct Injection (HDI) plus Gasoline Port (GPI) mode lean-burn conditions are reported. In this paper, effects two different modes SI present...

Using a cationic operational system in capillary isotachophoresis, millimolar concentrations of sodium were determined in the absence and presence of serum proteins. With several internal standards, the reproducibility of the sodium determination was significantly poorer in the presence of proteins, even after partial thermal degradation. The results are explained by protein-sodium interaction ...
