PURPOSE To prospectively evaluate whether ultrasonography (US)-guided vascular access can be learned and performed faster with the sonic flashlight than with conventional US and to demonstrate sonic flashlight-guided vascular access in a cadaver. MATERIALS AND METHODS Institutional review board approval and oral and written informed consent were obtained. The sonic flashlight replaces the sta...

Alkyd resins are amongst the most important and widely used resins in coating sectors. In this communication we report on preparation of alkyd resins emulsified by grafted acrylic resins on their fatty acid moieties. Both high-shear mechanical homogenizer and ultra-sonic sonicator were used step-wise to disperse the alkyd resin and acrylic based monomers in aqueous media. The resins are of nano...

Applications of the Web of Things reach from smart shoes posting your running performance online, over the localization of goods in the production chain, to computing the insurance cost of cars based on the actually driven kilometers. Thereby, Web of Things applications follow the REST paradigm, i.e. access to things and their properties is offered via REST APIs. This allows an easy meshing of ...

This paper addresses in-situ stress-estimation methods based on the Kaiser effect. The physical and mechanical properties of granite, diorite, granodiorite samples selected at different depth intervals core obtained from a wellbore were examined. ultimate uniaxial compressive strength, modulus elasticity, Poisson’s ratio rock determined using presses strain gauges. Also, local longitudinal shea...
