We present experiments and simulations of plunging maneuvers large amplitude, for velocity ratios 2, defined as the ratio between peak plunge freestream velocity. explore effect airfoil shape by considering a NACA 0012 wing flat plate. The are performed with wings aspect 4 4.86, whereas using model an infinite-aspect-ratio wing. report time evolution force coefficients flow visualizations. A go...

Plunge milling is a recent and efficient production mean for machining deep workpieces, notably in aeronautics. This paper focuses on the minimization of the machining time by optimizing the values of the cutting parameters. Currently, neither Computer-Aided Manufacturing (CAM) software nor standard approaches take into account the tool path geometry and the control laws driving the tool displa...

College and university science educators from across Connecticut gathered at Yale's West Campus in April 2010 for a Project Kaleidoscope (PKAL) program entitled "Taking the Plunge: Next Steps in Engaged Learning." Funded by the National Science Foundation (NSF) and co-sponsored by the Connecticut Conference of Independent Colleges (CCIC) and Yale's McDougal Graduate Teaching Center, the event w...

It seems likely that the first detection of gravitational waves with the LIGO/VIRGO/... interferometers will come from binary systems made of massive black holes of comparable masses, say with a total mass M ≃ 15M⊙ + 15M⊙. For such massive systems the gravitational-wave frequency at the last stable (circular) orbit (LSO) is very close to the location of the minimum of the detector’s noise spect...

The nicotinic acetylcholine (ACh) receptor converts transiently to an open-channel form when activated by ACh released into the synaptic cleft. We describe here the conformational change underlying this event, determined by electron microscopy of ACh-sprayed and freeze-trapped postsynaptic membranes. ACh binding to the α subunits triggers a concerted rearrangement in the ligand-binding domain, ...

In an economic sense, heartwater disease is the most important tick-borne faced by South African livestock farmers. Methods to control vary among farmers, and preferred method depends on prevalence of in a specific area. The cost-effectiveness different acaricide prevention methods against has not yet been determined amongst producers. study’s objective was determine used Africa. Data for this ...

Results Our study showed that healthy controls had a Tregs frequency of 4.1%. When Tregs frequency analyzed among HIV/AIDS patients who are yet to receive HAART we found a significant reduction in Tregs population i.e. 1.2%. Encouragingly this deep plunge in Tregs population was found to be restored and surged upon HAART up to 12.6%. However, these changes in percentages did not alter based on ...
