      Numerical investigation of the effects of dwell time duration in a two-stage injection scheme on exergy terms in an IDI diesel engine by three-dimensional modeling (pages 1–13)

      Energy and exergy analyses are carried out for various two-step injection schemes in which 25% of the total fuel is injected during the second pulse and the dwell time is increased from 5°CA to 30°CA by 5°CA increments. The exergy efficiency diminishes with the increase in dwell duration from 5°CA to 25°CA and then increases during the dwell duration of 30°CA. The cumulative heat loss exergy diminishes with the increase in dwell duration from 5°CA to 25°CA and then increases during the dwell duration of 30°CA.

      Inferior outdoor-exposed performances of encapsulated a-Si:H photovoltaic modules deposited with a high speed (pages 14–21)

      The modules deposited with the conventional deposition rate of 0.20 nm/sec have the small increase in the light-induced degradation against the outdoor exposure test than the light-induced degradation against the indoor light-soaking test. However, the modules deposited with the high deposition rate of 0.35 nm/sec have the significant difference in the light-induced degradation ratio between the indoor and outdoor tests. It is also to be noted that some modules have the trend that higher initial Pmax stimulates the higher light-induced degradation, and thus leads to lower stabilized Pmax.

      Esterification of hydrolyzed sea mango (Cerbera odollam) oil using various cationic ion exchange resins (pages 31–38)

      This study investigates the esterification of hydrolyzed sea mango (Cerbera odollam) oil using several cationic ion exchange resins. At moderate reaction temperatures, 60–100°C, Amberlyst 15 was found to be adequate in converting the hydrolyzed sea mango oil into esters. Further investigation revealed that the esterification reaction using the cationic ion exchange resins proceeds at a fast rate, whereby conversion of over 70% at moderate reaction temperature was achievable in less than 1 h of reaction time.

      Pilot-scale processing with alkaline pulping and enzymatic saccharification for bioethanol production from rice straw (pages 39–45)

      Motoi Sekine, Yukiharu Ogawa, Nobuhiro Matsuoka and Yoshiya Izumi

      Version of Record online: 13 JAN 2014 | DOI: 10.1002/ese3.28

      The main devices and operations of pilot-scale bioethanol production from rice straw. The relationship between resource input and product yield for each operation exhibited an exponential or logarithmic curves, thus there was an optimum quantity of resource input, approximately 2000–3000 BDkg in our pilot-scale study, for higher efficiency at each operation.
