PURPOSE Dietary nitrate supplementation has been shown to reduce the O2 cost of submaximal exercise and to improve high-intensity exercise tolerance. However, it is presently unknown whether it may enhance performance during simulated competition. The present study investigated the effects of acute dietary nitrate supplementation on power output (PO), VO2, and performance during 4- and 16.1-km ...

[1] We use the Mars Regional Atmospheric Modeling System (MRAMS) to simulate lake storms onMars, finding that intense localized precipitation will occur for lake size ≥10 km. Mars has a low‐density atmosphere, so deep convection can be triggered by small amounts of latent heat release. In our reference simulation, the buoyant plume lifts vapor above condensation level, forming a 20 km high opti...

Il est naturel de penser que les expériences émotionnelles associées au souvenir d’un événement passé sont des états émotionnels nouveaux et présents déclenchés par l’événement dont on se souvient. Cette conception commune a néanmoins été remise en question début du xxe siècle intellectuel...

Abstract Chemical reactions on asteroid parent bodies, such as aqueous alteration and the formation of organic solids, require a heat source. Radioactive decay in interiors these bodies is generally considered most important source, but impact-generated heating also likely to play role. Here we present high-velocity impact cratering experiments using thermocouples embedded target material direc...

The mass-radius relations for bare and crusted strange stars are calculated with bag model. Comparing these relations with the observed one derived from redshift, we address that the conclusions, that EXO 0748-676 can not be a strange star, is incorrect. Various strange star models can show that EXO 0748-676 could have a mass of (1.3 ∼ 1.7)M and a radius of (8.2 ∼ 10.6) km. It is proposed that ...

We present a method for obtaining atmospheric temperature, pressure, and number density profiles for small bodies through inversion of light curves recorded during stellar occultations. This method avoids the assumption that the atmospheric scale height is small compared with the radius of the body, and it includes the variation of gravitational acceleration with radius. First we derive the int...

We conducted meteor echo observations using the Buckland Park MF radar (35 S, 138 E) at 00:40{05:45LT on October 22, 1997. In addition to the usual full correlation analysis (FCA) technique to measure horizontal wind velocities from 60 to 100 km MF radars have a potential to detect meteor echoes and infer winds through their Doppler frequency shifts. Because of the relatively low radio frequenc...

Futures studies is a value knowledge and has a two-way communication with the worldview, ideology and culture of nations. Humanities is one of the factors that influence the field of futures studies. Hence the human sciences itself could be the subject of future studies. In this study, we have tried to discuss the role of future studies in knowledge management in the field of humanities. Theref...

Au niveau international puis national, des grandes entreprises ont justifié d’investir sur la « gestion de diversité » au nom ses bénéfices pour performance économique, discours repris par l’Union européenne. Ce programme décliné l’égalité ou « mixité » (au sens représentation &...
