Alcohols (1-hexanol, 1-heptanol, and 1-octanol), castor oil and Aliquat-336® were used for phenol extraction. In a typical extraction experiment involving shaking and allowing for phase separation, phenol (75-96%) can be extracted with different solvents using solvent-wastewater ratio (5:250 v/v). Generally, extraction (%) increased with solvent ratio; however, chain length of alcohols did not affect extractability of phenol much. Best extraction of phenol occurred into Aliquat 336. <br/> <br/>Page(s): 823-828 http://nopr.niscair.res.in/handle/123456789/5959 Title: Application of safety feature evaluation in single-use safety syringe design <br/> <br/>Authors: Chang, Eva; Wu, Fong-Gong; Chen, Rain <br/> <br/>Abstract: Reuse and abuse of syringes has led to cross-infection of diseases. Usability evaluation of three of the most commonly used safety syringe types conducted in this study is through-push retract breakable safety syringe, rotary plunger retractable safety syringe and release-ring breakable safety syringe. By administering Safety Feature Evaluation Form (SFEF) and Focus Group Interviews on six professional nurses with an average professional experience over 11 years, usability problems with three types of safety syringe are found out. Six design principles have been ascertained and applied in development of a new safety syringe design, with input from a number of designers, nursing professionals and occupational safety technicians. New safety syringe significantly outperformed existing safety syringes on all evaluation indices. <br/> <br/>Page(s): 817-822 http://nopr.niscair.res.in/handle/123456789/5958 Title: Rheological properties of crumb rubber modified bitumen-A lab study <br/> <br/>Authors: Kumar, Praveen; Mehndiratta, H C; Singh, K Lakshman <br/> <br/>Abstract: In this paper, bitumen is modified with crumb rubber (CR). Changes in rheological properties of 60/70 and 80/100 grades bitumen modified with CR have been studied for rheological properties using Dynamic Shear Rheometer (SR5 Ashphalt Rheometer). CR improves complex modulus and elastic response of bitumen at high temperatures. <br/> <br/>Page(s): 812-816 http://nopr.niscair.res.in/handle/123456789/5957 Title: Preparation and analysis of alkyd resin from deodourizer distillate <br/> <br/>Authors: Singh, Sibban <br/> <br/>Abstract: This study presents deodorizer (DO) distillate as a cheaper source of fatty acid to prepare alkyd resins. DO distillate-based alkyd resins provide encouraging film properties, except for color and clarity of resins. Thus, DO distillate based fatty acids are being explored as raw materials for alkyd resins in architectural coating applications. <br/> <br/>Page(s): 807-811
