Graphene oxide (GO) was deposited on the surface of a MnO2 air cathode by thermal evaporation at 50°C from a GO colloidal suspension. Fourier transformed infrared spectroscopy and field emission scanning electron microscopy confirmed the presence of GO on the MnO2 air cathode (GO-MnO2). Voltammetry and chrono-amperometry showed increased currents for the oxygen reduction reaction (ORR) in 6 M K...

INTRODUCTION in this study we report the functional results of 36 professional athletes treated with a combined percutaneous and mini-open technique. METHODS patients were evaluated with Victorian Institute of Sports Assessment-Achilles questionnaire (VISA-A), the objective 100-points Hannover scale and the Ergo-jump Bosco System device. RESULTS at a mean 28- month follow-up no re-rupture c...

Si aceptamos que la publicidad se basa en creatividad; creatividad, las ideas, y resolución de problemas, estaríamos incurriendo una sinécdoque conceptual, ya no contemplaríamos el ciclo vida completo dichas ideas. Cómo venden, ergo, cómo compran y, a postre, cuentan ideas es un camino parece haber trascendido desde mesa reuniones hacia espacios encuentro marcas con sus públicos, creciente ejer...

ERGO-MTM is an innovative model to set standard times of manual tasks. MTM, developed in the forties by industrial engineers, assigns a basic time to execute a given motion based on the concept of normal performance (speed, effort and precision). The traditional models to set a standard time then add to the basic time a fatigue allowance, applied on each individual motion, depending generally o...

Kognitive Dissonanzen sind eine der Barrieren für eine erfolgreiche Einführung von Wissensmanagement-Lösungen. Diese führen zu einer suboptimalen Zufriedenheit mit der Lösung und beeinflussen somit die Identifikation mit den Zielen des Wissensmanagements im Unternehmen negativ. Anhand eines Fallbeispiels der Fa. avanturo wird dies beschrieben und mögliche Gegenmaßnahmen aufgezeigt. 1 avanturo –...

This study compared a light meal combat ration (LMCR) to specific commercial sport drinks (CSD) and the effect of their ingestion on time to exhaustion during simulated combat maneuvers (SCM). The SCM consisted of three activities: a 2-hour march at 50% of maximal aerobic capacity (VO2max); a subsequent 1-hour run at 70% VO2max; and a run to exhaustion at 80% VO2max. During SCM, the subjects co...

Abstract Hydrogen uptake (H-uptake) is studied in ball milled Mg-B-electrochemically synthesized reduced graphene oxide (erGO) nanocomposites at P H2 ? 15 bar, ~ 320 °C. B/C (weight ratio): 0, 0.09, 0.36, 0.90 are maintaining erGO?10wt %. B occupies octahedral interstices within Mg unit cell—revealed by electron density maps. Persistent charge donations from and to C appear as Mg-C (~ 283.2 eV)...

Citizen Science or community science has been around for a long time. The scope of involvement in initiatives ranges from short-term data collection to intensive engagement delve into research topic together with scientists and/or other volunteers. Although many volunteer researchers have academic training, it is not prerequisite participation projects. It important adhere scientific standards,...
