Technology and the Myth of ‘Natural Man’

The main suggestions and objections raised by Don Ihde and Charles Lenay to my ‘Technology and the body: the (im)possibilities of re-embodiment’ are summarized and discussed. On the one hand, I agree that we should pay more attention to whole body experience and to further resisting Cartesian assumptions in the field of cognitive neuroscience and philosophy of cognition. On the other hand, I explain that my account in no way presupposes the myth of ‘natural man’ or of a natural, delineated body from before the fall into technology.

Demonstration of retinoic acid isomers in human urine under physiological conditions

Untransformed retinoic acid has never been demonstrated in human excreta under normal physiological conditions. We have developed a two-step liquid chromatographic system for the demonstration of subnanogram amounts of this compound in human urine without administration of any precursor.     

Observations on the toxicity and metabolic relationships of polygodial,the chemical defense of the nudibranchDendrodoris limbata

Summary Polygodial (1), the defense metabolite stored in the skin of the nudibranchDendrodoris limbata, is toxic for the mollusc itself when injected into the hepatopancreas. Biosynthetic experiments using labeled mevalonic acid were devised to investigate a possible metabolic relationship between1 and the mixture of sesquiterpenoidic esters2, stored in the hepatopancreas. The results suggest that1 and2 are biosynthesized by independent pathways.Thanks are due to G. Villani for supplyingDendrodoris limbata and to A. Trabucco for technical assistance.     

一种智能化双通道振动监视仪

在大型旋转机械状态监测的研究中，研制了一种智能化振动监视仪。它以高性能的８０Ｃ５２２单片横为核心，采用点阵式液晶显示技术，选用可编程逻辑阵列ＧＡＬ及串行的Ｅ＾２ＰＲＯＭ等先进器件。它采用硬软件结合的结构方式，具有两级越限报警记录输出以及现场设置运行参数，并能和上位机通讯等功能。     

合成C(10)卤代类前列腺素

１５—Ｏ—乙酰基—ＰＧＡ２甲酯（１）用过氧化氢环氧化，（１）的环氧化物在三苯膦作用下分别与１，２———二氯乙烷，溴或１———碘代戊烷作用，实现Ｃ（１０）的相应卤化。Ｃ（１０）卤代类前列腺素有明显的抗肿瘤活性。     

Membrane resting potentials in cultured mouse neuroblastoma cells

Summary Membrane resting potentials (MRP) were measured systematically in cultured mouse N₂A neuroblastoma cells: 1) in the logarithmic growth phase; 2) in subconfluent cultures; 3) in confluent cultures; 4) after dBcAMP had induced morphological differentiation. Neurite extension was accompanied by a significant increase in MRP as compared to the appropriate controls. No significant differences in MRP were observed with regard to the different growth phases.

辣椒脉斑驳病毒侵染性克隆构建的简易方法

本文介绍了一种构建辣椒脉斑驳病毒(Chilli veinal mottle virus , ChiVMV)侵染性克隆的简易方法. 基于辣椒脉斑驳病毒的全长确定序列, 根据基因内部的单一限制性酶切位点, 设计引物, 将ChiVMV分成KL1,KL2, KL3三个片段通过RT PCR和TA克隆的方法将3个片段构建到PMD19 T载体上. 通过双酶切将ChiVMV前面7000bp的片段构建到载体上, 从而将全部的ChiVMV cDNA分段构建到两个重组质粒中, 成功地避免了全长病毒序列在大肠杆菌中不稳定的现象. 进行体外转录时, 先通过PCR扩增出两个彼此有一定重叠的平末端片段, 再利用两个重叠片段为模板用重叠PCR的方法扩增出全长带T7启动子的ChiVMV cDNA, 并通过T7 RNA聚合酶成功转录出ChiVMV的病毒RNA.     

多轴全地面起重机稳态转向特性分析

根据拉格朗日法建立了多轴全轮转向车辆的三自由度动力学模型和运动微分方程,采用零质心侧偏角控制策略,研究了车辆作稳态转向时,其转向中心位置、横摆角速度增益及侧倾角增益如何随车速而变化,并且给出了稳态圆周行驶的评价指标。在零质心侧偏角控制策略下,讨论了多轴全轮转向车辆的转向特性,分析了影响转向性能的因素。为多轴全地面起重机的转向设计提供了理论依据。
