  • 简介:因为他们能生产许多种简历活性物质,陆上的酵母在科学和工业一直在收到大注意超过100年了。然而,很少对海洋的酵母的简历活性物质被知道。在最近的年里,它过时的人或物发现海洋的酵母在海洋生物养殖和另外的领域有宽应用程序。因此,海洋的酵母,从他们的简历活性物质和海洋的酵母的应用自己和他们生产了的简历活性物质在这篇论文被考察。

  • 简介:在研究和开发的十年以后,海洋的控制来源ElectroMagnetics(MCSEM)为油和煤气的探索进入了应用程序阶段。然而,一会儿3D当模特儿MCSEM与简单模型和许多计算时间一起是远非实际的。在复杂目标身体和它的敏感分析上基于3D频率域MCSEM的向前当模特儿的研究,我们导出能描出的一个方法抵抗水库的边。我们使用大小对偏移量(MVO)曲线的第二衍生物定义抵抗水库边。远为air-wave-dominated回答地区,我们用少些影响的明显的抵抗力建议以便改进方法的适应性。
