This paper presents a part of development non-standard method for testing cylindrical test specimens measurement fracture properties pipeline materials. structures working under pressure is based on determining mechanics parameters SENT (Single Edge Notched Tension) and new PRNT (Pipe Ring specimens. In this work, both types required were manufactured from polyamide PA12 by using SLS (selective...

First of all, the smelting equipment is most important component a foundry’s main production process and therefore requires constant reproduction. This ensured by timely high-quality maintenance repair, cost which 8–12% total costs. The technical economic conditions enterprise itself depend on this, as productivity workers during directly related to condition its downtime for repairs. An factor...

Background. Additive technologies based on Fused Deposition Modeling (FDM) modeling methods attract a lot of attention from both industry and research groups, which is explained by low investment costs, ease production, etc. If the processing parameters are correctly selected, products with mechanical properties close to obtained traditional can be obtained. Objective. Practical implementation ...

Abstract Objectives The main aim of the research was to analyze an economical and eco-friendly approach improve solubility norfloxacin. current analysis utilize hydrotropic solutions extract drugs from their dosage forms, avoiding use costlier harmful organic solvents. Materials Methods In this study, ultraviolet–visible spectrophotometer (model 1800, Shimadzu Corporation) used norfloxacin drug...

Water hyacinth is a weed in Rawa Pening because of its rapid growth. A handling effort very crucial thing and must be done immediately. This study aims to characterize organic compounds liquid smoke from dried water hyacinth. ­­­­Characterization was carried out on which pyrolyzed at 200°C 600°C. Pyrolysis times were run 2 hours 6 hours. Liquid distilled before testing chemical composition usin...
