The best catalytic activity and selectivity could be found in the prepared catalyst system with the optimum combination of the ionic liquid, nano-Pd, and support. The stabilizer is also used to prevent the aggregation of nano-Pd particles. One of the advantages of this approach is that the prereduction of catalyst is not required.

其中离子液体、奈米钯金属及担体皆有其功能，三者之组合才能达到良好之效果，同时，在合成奈米钯过程中，必须使用稳定剂以避免奈米钯金属之聚集此触媒系统之另一优点为不需先加氢还原处理，耐水性强且可重覆使用，是一种颇具潜力之选择性氢化触媒。

The colon temperatures were measured by a thermistor and the cytosolic free calcium concentration ([Ca2+]i) in dissociated brain cells was measured by Fura 2-AM. The results demonstrated that the pyretic action of egtazic acid (0.6 μmol, icv) was markedly inhibited by DEX (5 mg/kg,iv), but DEX (60-120 μmol/L) did′t affect [Ca2+]i in dissociated hypothalamus cells. Actinomycin D, which interferes with gene transcription (3 nmol, icv), completely abolished the antipyretic action of DEX on egtazic acid-induced fever.

结果发现：脑室灌注乙二醇双(2-氨基乙醚)四乙酸(0.6 nmol)引起家兔结肠温度明显升高，静脉注射地塞米松(5 mg/kg)显著抑制家兔乙二醇双(2-氨基乙醚)四乙酸性发热，地塞米松(60-120 μmol/L)并不影响下丘脑细胞内[Ca2+]i，而事先脑室灌注抑制基因转录的放线菌素D(3 nmol)则完全取消了地塞米松对乙二醇双(2-氨基乙醚)四乙酸性发热的解热作用。

However, seme environmental problems such as eutrophication,bacterial contamination and erosion of lake-shore have been brought about due to the improper management of the lake and no attention having been paid to its environmental protecticr.

The experts behind the discovery say elephants are capable of vocal imitation, joining a select group of animals that includes parrots, songbirds, dolphins, and humans.Zoologist Joyce Poole was the first to notice some rather unelephantine noises emanating from a group of semiwild, orphaned elephants in Tsavo National Park, Kenya. She managed to track the sounds to a female named Mlaika. But the ten-year-old's powers of mimicry were so developed that the task wasn't easy."I was sometimes unable to distinguish between the distant trucks and Mlaika's calling," said Poole, the scientific director of the Amboseli Elephant Research Project."This is what first made me wonder whether she could possibly be imitating the truck sounds."Poole said others in Mlaika's group have been heard to make a similar noise, which is quite different from any call previously recorded in elephants.

据美国《国家地理》杂志网站3月23日报道，进行这项研究的科学家表示，与鹦鹉、某些鸣禽、海豚和人类一样，大象具有模仿声音的能力t921.com动物学家乔伊斯·普尔是安博塞利大象研究计划的负责人，也是第一个注意到这种现象的人t921.com她在肯尼亚安博塞利国家公园里，发现了一群半野生的、孤儿大象的象群发出了不同寻常的奇怪叫声t921.com普尔曾试图通过声音来追踪一只名为米爱卡的雌性大象，但是这只10岁大象出色的模仿能力让普尔的任务变得并不简单t921.com普尔说：&有些时候，我简直分不清究竟是远方的卡车发出的声音还是米爱卡的叫声，这让我非常好奇，我想是不是米爱卡能够模仿卡车行驶的声音呢？&

The content of tocopherols and toctrienols in rice bran oil and its deodorizer distillate were analyzed, and the unsaponifiable matters components in the deodorizer distillate were also studied.

对米糠油及其脱臭馏出物中生育酚及生育三烯酚含量进行检测分析，结果表明，米糠来源和米糠油精炼工艺对米糠油及其脱臭馏出物中α、β、γ、δ-生育酚和生育三烯酚的含量有显著影响。

Younger children whose mothers took fish-oil supplements (which contain omega-3s) when they were pregnant and while they were breast-feeding do show better cognitive performance than their unsupplemented contemporaries.

虽然，欧米茄-3对于健康学龄儿童的影响还有待研究，但是，戈麦斯-皮尼拉博士说，母亲在怀孕和哺乳期间服用含欧米茄-3的鱼油营养品的孩子们，确实在认知能力上要比那些母亲在怀孕和哺乳期间不服用含欧米茄-3的鱼油营养品的孩子们表现得更好。

Moreover, although more work is needed to elucidate the effects of omega-3s on healthy school-age children, Dr Gómez-Pinilla says that younger children whose mothers took fish-oil supplements (which contain omega-3s) when they were pregnant and while they were breast-feeding do show better cognitive performance than their unsupplemented contemporaries.
