in production of tissue paper, the adhesion of a liquid adhesive creping aid, compound polymer, as creping aids on the yankee dryer surface was investigated. a compound polymer was prepared based on mixing ratio of poly (amideamine)-epichlorohydrin resin (pae) as an adhesive agent, polyvinyl alcohol (pva) as a modifier agent, and cationic fatty acid (cfa) and ethylene glycol (eg) as release age...

background: sickle cell disease is a genetic disorder of hemoglobin causing myriad of pathology including anemia. the purpose of this study was to evaluate the baseline values of steady state hemoglobin and packed cell volume as a guide to managing the early recognition of hemolytic crises in sickle cell anemia. methods: a cross-sectional study was conducted among the sickle cell patients atten...

The aim of this paper is to study the effect of substrate on the Cu3N thin films. At first Cu3N thin films are prepared using DC magnetron sputtering system. Then structural properties, surface roughness, and electrical resistance are studied using X-ray diffraction (XRD), the atomic force microscope (AFM) and four-point probe techniques respectively. Finally, the results are investigated and c...

Due to developments in additive manufacturing, the production of piezoelectric materials with complex geometries is becoming viable and enabling the manufacturing of thicker harvesters. Therefore, in this study a piezoelectric harvesting device is modelled as a bimorph cantilever beam with a series connection and an intermediate metallic substrate using the plain strain hypothesis. On the other...
