The methanol extracts of 168 plant species from 68 families were evaluated for their inhibitory activity against lettuce seedling elongation. Among the plant species tested, 12 species had EC50 values for radicle growth inhibition ranging from 0.01 to 5.00 mg fresh weight equivalent mL-1. Enterolobium contortisiliquum, a traditionally used herbal medicine, exhibited the strongest inhibitory activity (estimated EC50: 0.28 fresh weight equivalent mL-1). Among the 12 species, Pachysandra terminalis, Tamarindus indica, and Albizia guachapele required investigation, because only little has been reported about their chemical constituents to date. The data in the present study would be useful in finding new lead compounds for natural herbicides.

A 56-year-old man with a history of old myocardial infarction and coronary artery bypass grafting was performed percutaneous coronary intervention to the totally occluded lesion of native left anterior descending artery. He developed a coronary arterial perforation that led to a large dissecting sub-epicardial hematoma. Emergent surgery was performed, and a large hematoma was removed from the sub-epicardial space. Continuous drainage of blood was observed after surgery, and the patient died due to the development of multiorgan dysfunction. An autopsy revealed an extensive sub-epicardial hematoma on the lateral wall of the left ventricle and broad necrosis of the myocardium in the lateral wall.

The Mechanism of Pb removal from brass scrap by compound separation using Ca and NaF addition was investigated. Because large Ca-Pb compound particles formed by Ca addition rise to the surface of the molten brass, they can be skimmed off from the molten brass. However, fine Ca-Pb compound particles remain in the molten brass because of low buoyancy. By subsequent NaF addition, the reaction between Ca-Pb compound and NaF takes place at their contact regions, resulting in the formation of solid CaF2, liquid Pb and Na gas. Pb is mainly present at the Ca-Pb compound-CaF2 interface. CaF2 acts as a binder for aggregation of fine Ca-Pb compound particles, resulting in the formation of light and large composite compounds, which rise to the surface of the molten brass. A high Pb removal rate is achieved by skimming off.

Wastewaters containing phosphorus and nitric acid are produced during biological treatment processes. In this study, a material for treating such wastewaters was developed. Foamed glass was produced from waste glass and then heated with iron sulfate to prepare an adsorbent for phosphorus and carrier for reducing nitric acid. The adsorbent performance was evaluated in batch and continuous experiments. The saturated adsorption amount of phosphate was 6.23 mg/g for the product obtained from glass of size 3 to 12 mm;the amount adsorbed was relatively high, in spite of the large glass size. The denitrification by reduction of nitrate was around 25%.

利用脑电磁图示(MEG)的方法对听觉诱发磁场(AEFs)与由自相关系数(ACF)以及由双耳互相关系数(IACF)中导出的因子的关系加以检验.首先,检验ACF,(?)的峰值对AEFs的影响,发现音调的强度与(?)良好相关,而当刺激开始后大约100ms时在左右颞叶上发现的N1m的振幅则随(?)的增加而增大.此结果表明较强声调感的声音导致N1m幅值的增加.此外,对IACC以及τ_(IACC)对AEFs的作用也加以检验,发现人类侧向声音定位的能力随IACC的减小而变差.当IACC为0.95时,N1m幅值随τ_(IACC)的增加而增加,而当IACC为0.5时,τ_(IACC)对N1m幅值的作用不显著.此结果表明侧向声音定位的能力可由N1m的幅值来反映.

Livestock wastewater is mainly treated with activated sludge, but ions such as phosphorus, potassium, ammonium, nitrate and sulfate remain in the effluent. In this study, the effects of residual ions on phosphorus recovery using the magnesium potassium phosphate crystallization method were investigated when magnesium was added to increase the pH. If co-existing ions affect the products, the phosphorus to potassium molar ratio (K/P ratio) of the precipitate will deviate from being equimolar. Artificial wastewater test solutions containing 5.6 - 20.3 mM ammonium, 25.6 mM potassium, 6.5 mM phosphorus, 0 - 7.35 mM nitrate, and 0 - 3.06 mM sulfate were used. First, the optimum operating pH and amount of magnesium added to give a high phosphorus removal rate and recovery rate were determined. The experimental setup was a 10 L aerated and stirred reactor, and a 5 L settling tank. The K/P ratio in precipitate was approximately 1 using the optimum conditions. Continuous 2 h treatment allowed a white precipitate containing about 30 g of needle-like crystals to be obtained. Next, the effects of varying the ammonium, nitrate, and sulfate ion concentrations in the artificial effluent were investigated. Ammonium and sulfate ion concentrations of 8 mM or more and 3 mM or more, respectively, caused the K/P ratio to decrease to about 0.7 and 0.5, respectively. Varying the nitrate concentration did not affect the K/P ratio, even at a nitrate concentration of 7.35 mM.
