Characterization, performance evaluation and optimization of wheat straw – bagasse blended fuel pellets

International Journal of Renewable Energy Development
This study was carried out to assess the fuel pellets produced from wheat straw and sugarcane bagasse. The wheat straw and bagasse were blended into four ratios including; 10:90, 30:70, 70:30 and 90:10 (wheat straw: bagasse) and developed into fuel ...

Shortest Recurrence Periods of Forced Novae

, 2016
We revisit hydrogen shell burning on white dwarfs (WDs) with higher mass accretion rates than the stability limit, \dot M_stable, above which hydrogen burning is stable. Novae occur with mass accretion rates below the limit.

Revision of the 15N(p,{\gamma})16O reaction rate and oxygen abundance in H-burning zones

, 2011
The NO cycle takes place in the deepest layer of a H-burning core or shell, when the temperature exceeds T {\simeq} 30 {\cdot} 106 K. The O depletion observed in some globular cluster giant stars, always associated with a Na enhancement, may be due to ...

Evaluation of burning rate in ECSP based on the voltage, pressure and initial temperature

FirePhysChem
Electrically controlled solid propellants (ECSP) have attracted extensive attention due to the tunable burning rate. The burning rate of ECSP determines the applying background of propellants and rocket engine structural design.

Influence of biomass burning during recent fluctuations in the slow growth of global tropospheric methane [PDF]

, 2006
During the past 15 years the annual growth rate of tropospheric methane (CH4) has shown striking changes over 2-3 year periods, varying from + 1% yr-1 to slightly negative values (-0.2% yr-1). These fluctuations are superimposed on an overall slowdown of
