Abstract In this article, Lewis acid–base complex of lithium 12-hydroxystearate (LHS) with diboron compound is formed by the introduction bis(pinacolato)diboron (B 2 Pin ) into grease. The interaction between acid B and base RCO ? LHS characterized various techniques. Moreover, rheological tribological behaviors grease are evaluated at low moderate temperature. results indicate that addition ca...

Previous research has revealed that corruption is considered to have two types of effects on the economy. Corruption seen as an obstacle economy but also a "grease wheel" accelerates rotation economic cogs. This study aims determine position in Indonesia after fiscal decentralization. The was conducted based secondary data obtained from publications Central Statistics Agency and Eradication Com...

Mechanical degradation by shear is one of the mechanisms that limits life-time lubricating grease in a rolling bearing. It results change micro-structure thickener–oil system, leading to bleed and consistency. The resistance can be quantified using worker. In this article, novel approach described, where worker used measure rheological properties situ, while aging grease. energy pressure losses...

Perfluoroalkyls constitute a class of compounds that have been used extensively in surface coating and protectant formulations due to their unique surfactant properties. Major applications have included protectants for paper and cardboard packaging products, carpets, leather products, and textiles that enhance water, grease, and soil repellency. Perfluoroalkyls have also been used as processing...

We report an unusual case of a patient with an epidural fluid collection with signal characteristics mimicking an epidural hematoma. The patient presented with myelopathy caused by thoracic spinal cord compression after a traumatic injury to the chest and back. The injury was caused by high-pressure injection of industrial-grade lubricant grease. This case demonstrates that cord compression can...

We report direct and absolute temperature measurements in a diode-end-pumped Yb:YAG crystal, using a calibrated infrared camera, with a 60-μm spatial resolution. The heat transfer coefficient has been measured, for the first time to our knowledge, with four different types of thermal contact (H = 0.25, 0.28, 0.9 and 2.0 for bare contact, graphite layer, indium foil and heat sink grease respecti...
