Three experiments explored the impact of mourning rituals after losses – of loved ones, lovers, and lotteries – on mitigating grief. Participants who were directed to reflect on past rituals or who were assigned to complete novel rituals after experiencing losses reported lower levels of grief. Increased feelings of control after rituals mediated the link between use of rituals and reduced grie...

Secondary organic aerosol (SOA) constitutes a major fraction of submicrometer atmospheric particulate matter. Quantitative simulation of SOA within air-quality and climate models--and its resulting impacts--depends on the translation of SOA formation observed in laboratory chambers into robust parameterizations. Worldwide data have been accumulating indicating that model predictions of SOA are ...

In this study, the performance of a single cylinder four stroke direct injection (DI) diesel engine is analyzed in the light of first law of thermodynamics. An energy balance study is carried out to quantify the various losses associated with diesel engine processes on the basis of experimental performance and emission data. The engine was fuelled with normal diesel and Jatropha Methyl Ester (J...

due to the high efficiency and low switching losses of resonant power convertors in comparison with switching convertors, nowadays there is a growing trend towards these convertors. however, because of the high frequency of switching in such convertors, it is quite difficult to present an efficient control method. in this paper, based on the state feedback method and using pole placement techni...

During Operation Enduring Freedom and Operation Iraqi Freedom (OEF/OIF), there were 375 rotorcraft losses with 496 fatalities from October 2001 to September 2009. Mishaps accounted for 81 percent of all losses with combat losses (i.e., aircraft shootdowns) accounting for the remaining 19 percent; 73 percent of the fatalities occurred in a combat theater. The OEF/OIF combat hostile action loss r...

The inelastic scattering of fast electrons transmitting thin foils of silicon (Si), silicon nitride (Si(3)N(4)), gallium arsenide (GaAs), gallium nitride (GaN) and cadmium selenide (CdSe) was analyzed using dielectric theory. In particular, the impact of surface and bulk retardation losses on valence electron energy-loss spectroscopy (VEELS) was studied as a function of the foil thickness. It i...

BACKGROUND There is growing evidence that tight glycemic control may be more harmful than beneficial in older persons with Type 2 diabetes (T2DM). It remains controversial if tight glycemic control (lower glycated hemoglobin A1c (A1c)) is associated with functional impairments in older frail patients with T2DM. We explored associations between A1c and losses in Activities of Daily Living (ADLs)...
