A number of tests and measurements of rubber compound properties were used to find the best ratio of soot and rubber powder. Guidelines to what percentage of recycled rubber powder should be added in a compound without affecting mechanical properties of finished rubber products are also provided. <br/> <br/>Page(s): 295-298 Thu, 29 Mar 2012 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/13761 Title: Ultrasonic assisted <i>in situ </i>transesterification of Jatropha seed to biodiesel <br/> <br/>Authors: Chadha, Poonam; Arora, Ajay K; Prakash, Shanti; Jha, Mithilesh K; Puri, Suresh K; Tuli, Deepak K; Malhotra, Ravinder K <br/> <br/>Abstract: This study presents a laboratory scale process for <i>in-situ </i>transesterification of Jatropha seeds to biodiesel under ultrasonic irradiation. Biodiesel with best yield and quality was produced at following conditions: seed/methanol (w/v) ratio, 1:10; reaction time, 80 min; and catalyst conc., 1% (w/w). <br/> <br/>Page(s): 290-294 Thu, 29 Mar 2012 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/13760 Title: Potential vegetable oils of Indian origin as biodiesel feedstock — An experimental study <br/> <br/>Authors: Agarwal, Madhu; Singh, Kailash; Upadhyaya, Sushant; Chaurasia, S P <br/> <br/>Abstract: This study presents various vegetable oils from edible and non-edible sources for preparation of biodiesel using KOH as catalyst and methanol as alcohol. Maximum biodiesel yield from all vegetable oils was obtained under following optimum conditions: reaction temp., 70°C; reaction time, 1 h; catalyst amount, 1% (by oil wt); and methanol to oil molar ratio, 6:1. Characteristics of biodiesel at optimum conditions were as per ASTM standards. <br/> <br/>Page(s): 285-289 Thu, 29 Mar 2012 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/13759 Title: Formulation and development of antipsoriatic herbal gelcream <br/> <br/>Authors: Kuchekar, Shantanu; Bhise, Kiran <br/> <br/>Abstract: This study presents formulation and development of patient friendly antipsoriatic topical gelcreams using Simulgel NS and Sepicide HB with Myrrh oil. Optimized formulation F5 depicted that gelcream had a viscoelastic nature with good creep recovery, and non-Newtonian behavior. Stability studies for three months at 40± 2^oC and 75±5% RH of Formulation F5 showed no change in colour and consistency, and pH remained between 5.7 and 5.9. Primary skin irritation test conducted on 30 healthy volunteers demonstrated nonirritating nature of F5. Thus Simulgel NS and Sepicide HB (conc., 2% w/v each) were found to give better anti-inflammatory gelcream containing myrrh oil with good consistency and stability. <br/> <br/>Page(s): 279-284 Thu, 29 Mar 2012 22:58:59 GMT
