F2TE3: A Transparent semi-monocoque VIP Envelope

This article examines a new lightweight, slim, high energy efficient, light-transmitting, selfsupporting envelope system, providing for seamless, free-form designs for use in architectural projects. The system exploits vacuum insulation panel technology. The research was based on envelope components already existing on the market and patents and prototypes built by independent laboratories, especially components implemented with silica gel insulation, as this is the most effective transparent thermal insulation there is today.

F²TE³: A Transparent semi-monocoque VIP Envelope

This article examines a new lightweight, slim, high energy efficient, light-transmitting, self-supporting envelope system, providing for seamless, free-form designs for use in architectural projects. The system exploits vacuum insulation panel technology. The research was based on envelope components already existing on the market and patents and prototypes built by independent laboratories, especially components implemented with silica gel insulation, as this is the most effective transparent thermal insulation there is today. The tests run on these materials revealed that there is not one that has all the features required of the new envelope model, although some do have properties that could be exploited to generate this envelope, namely, the vacuum chamber of vacuum insulation panels, the use of monolithic aerogel as insulation in some prototypes, and reinforced polyester barriers. These three design components have been combined and tested to design a new, variable geometry, energy-saving envelope system that also solves many of the problems that other studies ascribe to the use of vacuum insulation panels.

VIP and PACAP potentiation of nicotinic ACh-evoked currents in rat parasympathetic neurons is mediated by G-protein activation

The effects of vasoactive intestinal polypeptide (VIP) and pituitary adenylate cyclase-activating polypeptide (PACAP27 and PACAP38) on isolated parasympathetic neurons of rat intracardiac and submandibular ganglia were examined under voltage clamp using whole-cell patch-clamp recording techniques. VIP and PACAP (less than or equal to 10 nm) selectively and reversibly increased the affinity of nicotinic acetylcholine receptor channels (nAChRs) for their agonists resulting in a potentiation of acetylcholine (ACh)-evoked whole-cell currents at low agonist concentrations. VIP-induced potentiation was observed with either ACh or nicotine as the cholinergic agonist. The VIP- but not the PACAP-induced potentiation of ACh-evoked currents was inhibited by [Ac-Tyr(1), D-Phe(2)]-GRF 1-29, amide (100 nm), a selective antagonist of VPAC(1) and VPAC(2) receptors; whereas the PACAP38- but not the VIP-induced potentiation was inhibited by 100 nm PACAP6-38, a PAC(1) and VPAC(2) receptor antagonist. The signal transduction pathway mediating VIP- and PACAP-induced potentiation of nicotinic ACh-evoked currents involves a pertussis toxin (PTX)-sensitive G-protein. Intracellular application of 200 mu m GTP gamma S or GDP beta S inhibited VIP-induced potentiation of ACh-evoked whole-cell currents. GTP gamma S alone potentiated ACh- and nicotine-evoked currents and the magnitude of these currents was not further increased by VIP or PACAP. The G-protein subtype modulating the neuronal nAChRs was examined by intracellular dialysis with antibodies directed against alpha(o), alpha(i-1,2), alpha(i-3) or beta G-protein subunits. Only the anti-G alpha(o) and anti-G beta antibodies significantly inhibited the effect of VIP and PACAP on ACh-evoked currents. The potentiation of ACh-evoked currents by VIP and PACAP may be mediated by a membrane-delimited signal transduction cascade involving the PTX-sensitive G(o) protein.

Plan de marketing para Vip Dating Perú

El Plan de Marketing propuesto tiene como objetivo establecer la forma de expansión y comunicación de la empresa Vip Dating Perú en el territorio peruano. Para ello, se realizó una investigación de mercado que ayudó a concretar cuáles son las preferencias y el conocimiento que existe de nuestro público objetivo. Asimismo, esta investigación revela que Vip Dating Perú tiene potencial de crecimiento y la marca goza de muy buena aceptación. En lo que se refiere a la estrategia de crecimiento, se determinó expandir las operaciones a las principales ciudades del Perú, Arequipa y Trujillo, realizando un número determinado de eventos por año en cada una de ellas. Por tal motivo, en mayo del 2015 se inició la campaña de promoción y publicidad en Arequipa. Hubo una gran acogida por parte de los medios de comunicación puesto que el servicio es bastante novedoso para la ciudad. Finalmente, el diagnóstico situacional revela más oportunidades y fortalezas que amenazas y debilidades, lo que genera un entorno favorable para el desarrollo del negocio. Esto se verá plasmado en la formulación estratégica de marketing que guiará el logro de los objetivos propuestos.
