A large-eddy simulation (LES) of a bluff-body-stabilized flame has been carried out using a new strategy for LES grid generation. The recursive filter-refinement procedure (RFRP) has been used to generate optimized clustering for variable density combustion simulations. A methane–hydrogen fuel-based bluff-body-stabilized experimental configuration has been simulated using state-of-the-art LES a...

Testosterone has been associated with economically egoistic and materialistic behaviors, but -defensibly driven by reputable status seeking- also with economically fair, generous and cooperative behaviors. Problematically, social status and economic resources are inextricably intertwined in humans, thus testosterone's primal motives are concealed. We critically addressed this issue by performin...

Neck lumps are a common yet challenging clinical presentation that can occur in all age groups and have wide variety of aetiologies include both benign malignant conditions. Appropriate workup timely referral critical, particularly when investigating for malignancy. Our case demonstrates rare cause neck lump presented clinically radiologically as primary malignancy, however, was found at histop...

TECHNICAL NOTES are short manuscripts describing new developments or important results of a preliminary nature. These Notes cannot exceed six manuscript pages and three figures; a page of text may be substituted for a figure and vice versa. After informal review by the editors, they may be published within a few months of the date of receipt. Style requirements are the same as for regular contr...

June 2005 was to bring online gambling out of the shadows and into the spotlight. PartyGaming, a start-up formed in 1997, launched a flotation (Initial Public Offering) on the London Stock Exchange that valued the firm at d4.64 billion giving it a larger market capitalisation than British Airways. PartyGaming had become the dominant player in the booming online poker market with its PartyPoker ...

Piezoelectric energy harvesters (PEHs) are a kind of harvester that generates electricity due to pressure or vibration. Vortex-induced vibration (VIV) is method utilized wind and bluff body generate the in PEH. The objective this research was study output voltage different bodies with various airflow velocities. Experimental simulation have done study. used PEH consists piezoelectric bimorph re...

A numerical study of the wake dynamics and stability of the flow around bluff rings placed normal to the flow direction at low Reynolds number is presented. An attractive feature of this bluff body geometry is that it effectively behaves locally like a circular cylinder at high aspect ratio while, as the aspect ratio is reduced to zero, the body is transformed to a sphere. Thus, it covers a ric...

Pollen and high-resolution charcoal data from Bluff Lake and Crater Lake, California, indicate similar changes in climate, vegetation and fire history during the last 15 500 years. Pollen data at Bluff Lake suggest that the vegetation between c. 15 500 and 13 100 cal. BP consisted of subalpine parkland with scattered Pinus and Abies. After 13 100 cal. BP a relatively closed forest of P. montico...
