1. Synthesis and Antioxidant and Antimicrobial Properties of β-Hydroxy Sulfides, Sulfoxides, and Sulfones Derived from Cardanol and Glycerol Derivatives
Natural and synthetic sulfur-bearing organic compounds have many applications in medicinal chemistry. This article reports the preparation of amphiphilic β-hydroxy sulfides, sulfoxides, and sulfones derived from cardanol and glycerol. Thiolysis of cardanol epoxide 3 with various thiols (4a-4j) in ethanol or water yielded the corresponding β-hydroxy sulfide

2. Advances in the biomedical applications of reactive colloids
This short review aimed to give to reader's brief applications of polymer colloids in biomedical area such as therapy and medical diagnosis as also developed in our laboratory. Indeed, the polymer particles and composite particles are commonly used in immunoassays as solid phase supports, for the encapsulation of active agents and for the immobilization of b

3. Active magnetic bearing applied to a tubular linear induction motor. / Mancal magnético ativo aplicado a um motor de indução linear tubular.
A tubular linear induction motor applied to onshore oil exploitation, named MATÆOS (which is in the Portuguese acronym for Tubular Asynchronous Motor for Onshore Oil Exploitation) was built at Escola Politécnica da Universidade de São Paulo (EPUSP). Its purpose is to directly drive the sucker-rod pump installed in the down hole of the oil well. In continu

4. Single axis controlled attraction type magnetic bearing
This paper presents a new type of magnetic bearing with active control only in axial direction. The bearing uses two pairs of permanent magnets working in attraction mode to restrict the radial motion and a control system composed of two electromagnets, a gap sensor and a controller to keep the axis in a fixed axial position. The principle, the dynamic model

5. Activation of fusimotor neurones by motor cortical stimulation in human subjects.
1. Neural recordings were made from motor fascicles of the ulnar or radial nerves while the motor cortex was stimulated percutaneously using high-voltage electrical stimuli or transient magnetic pulses to determine whether human muscle spindle endings could be activated by such stimuli and, if so, whether this occurred before the recruitment of alpha-motoneu
