What is Pure: Definition and 499 Discussions

Propulsion Universelle et Récupération d'Énergie (PURE; English: Universal Propulsion and Energy Recovery) was a motorsports engineering company founded by former British American Racing team principal Craig Pollock in 2011. It aimed to design and manufacture engines for use under the 2014 Formula One technical regulations, that mandate a switch from the current normally aspirated V8 engines to turbocharged V6 engines. The company was linked to Mecachrome, and employed former members of Renault and Peugeot's 1990s Formula One engine programmes.In July 2011, the company secured the services of Gilles Simon, formerly head of Scuderia Ferrari's engine department and the FIA technical director for powertrain development. The recruitment was controversial, with several teams and manufacturers – particularly Renault – expressing concerns that Simon's previous position with the FIA would grant him access to sensitive technical data about engine designs that could potentially be used by PURE in the development of their own engine. Simon and PURE rejected these suggestions, stating that the process of developing the 2014 engine regulations had been transparent, and that all parties involved had access to the same information so that no individual group would have an advantage. PURE used Toyota Motorsport's facilities in Cologne, Germany, whilst also maintaining a French base. In July 2012, PURE suspended its engine programme due to a lack of funding and later ceased operations.

    Is Modeling or Pure Mathematical Equations Better for Analyzing Capacitors?

    Hi, When modelling something such as a capacitor using a method like Boundary Element Analysis (BEM) then this may lead you to a visual model i.e it shows you the charge across the plates or the density of the fringing field, rather than a method which uses a pure mathematics such as Gauss'...

    KNO3 Stump Remover: Is 13-0-44 Pure Enough?

    I have bought a stump remover for KNO3 and it has the numbers 13-0-44, which i have heard is pretty good. I was just wondering, how pure is it? and also if i could remove those impurities. I have tried making BP with it and it didn't do much. lots of excess sulfur and charcoal was left over, so...

    Nuclear Decay: Pure Beta vs. Mixed Beta/Gamma Emitters

    This may be better suited for the nuclear engineering forum, so feel free to move it. In decay processes that involve beta decay (or positron decay), there are pure beta emitters and mixed beta/gamma emitters. What determines whether a specific nuclide is just a pure emitter as opposed to a mixed?

    What is the Van't Hoff factor for NaCl in seawater?

    X_1=\frac{n_1}{n_1+n_2}\implies n_2=\frac{n_1-X_1n_1}{X_1} where n1 is the moles of solvent and n2 is the moles of solute. 22.98=X_1\left(23.76\right)\implies X_1=.9672 and 1000 g of water is equal to 55.49 mol (n1), so plugging this all in gives: n_2=1.88\text{mol} which would be...

    Can Quantum Mechanics be seen as pure geometry ?
