Pt/Ir electrodes have been extensively used in neurophysiology research in recent years as they provide a more inert recording surface as compared to tungsten or stainless steel. While floating microelectrode arrays (FMA) consisting of Pt/Ir electrodes are an option for neuroprosthetic applications, long-term in vivo functional performance characterization of these FMAs is lacking. In this stud...

Temperature control is a key factor which affects the construction quality of the mass concrete, which is also an important measure to prevent crack propagation. Lots of engineering practices show that most of temperature cracks come out in the form of the surface crack during the construction of the concrete dam. In addition, deep cracks and transverse cracks are usually developed by surface c...

This paper describes a simple and reliable method of improving the surface insulation strength of a spacer used in vacuum. The method is to roughen the spacer surface to an average roughness R higher than 1 or 2 m. The material of the spacer a examined is SiO , PMMA, PTFE or Al O and their shape is a right cylinder with 2 2 3 10 mm in height and 54 mm in diameter. The spacer is subjected to a r...

Polymeric insulators need proper management and maintenance. Without proper management, the electric devices can be affected by factors such as leakages in the electricity system. In outdoor insulation, the environment subjects the material to a variety of stresses simultaneously that can lead to rapid degradation and loss of the insulation properties. Contamination of the surface of the insula...

although in recent two decades, the concept of dielectric barrier discharges (dbds) have been developed in ozone production well, air pollution control, plasma screens and control of chemical, and biological and medical processes, employment of this concept for high voltage applications to improve insulation performance as an alternative to the pressurized gas-insulated systems (gis) utilizing ...

Analytical, numerical and experimental analyses have been performed to investigate the effects of thermocouple wire electrical insulation on the temperature measurement of a reference surface. Two diameters of type K thermocouple, 80 mm and 200 mm, with different exposed wire lengths (0 mm, 5 mm, 10 mm, 15 mm and 20 mm) were used to measure various surface temperatures (4 C, 8 C, 15 C, 25 C and...

INTRODUCTION In a cold, wet, or windy environment, cold exposure can be considerable for an injured or ill person. The subsequent autonomous stress response initially will increase circulatory and respiratory demands, and as body core temperature declines, the patient's condition might deteriorate. Therefore, the application of adequate insulation to reduce cold exposure and prevent body core c...

The acoustic insulation provided by separating walls has been studied for many years, with the first publications dating from the early part of the 20th century [1]. Since then, different analytical and numerical models, for predicting the sound transmission via single and multi-panel walls, have been proposed. However, given the large number of variables of this problem and the uncertainties i...

INTRODUCTION In the prehospital care of a cold and wet person, early application of adequate insulation is of utmost importance to reduce cold stress, limit body core cooling, and prevent deterioration of the patient's condition. Most prehospital guidelines on protection against cold recommend the removal of wet clothing prior to insulation, and some also recommend the use of a waterproof vapor...
