The effects of acoustic and visual stimuli and their synergistic effects on heart rate variability including gender differences were investigated. Of particular interest was the influence of visual stimulus on heart rate variability during listening to simple sounds of different characters. Twelve male and 12 female university students were selected as subjects. The subjects listened at rest to...

The design (or evaluation) of military aircraft, by nature, is a process consisting of conflicting goals and objectives at the conceptual, preliminary, and detailed level. Affordability, mission capability, availability (operational readiness), wartime survivability, and peacetime safety are five of the main attributes required of modern weapon systems. Traditional approaches for system evaluat...

The development of active, cost-effective and stable oxygen-evolving catalysts is one of the major challenges for solar-to-fuel conversion towards sustainable energy generation. Iridium oxide exhibits the best available compromise between catalytic activity and stability in acid media, but it is prohibitively expensive for large-scale applications. Therefore, preparing oxygen-evolving catalysts...

Energi panas bumi pemanfaatannya masih belum maksimal di Indonesia. Hingga tahun 2020 realisasi pengembangan menjadi listrik adalah sebesar 2.130,7 MW. Salah satu pembangkit (PLTP) Indonesia yang telah beroperasi Sarulla Geothermal Power Plant. Kapasitas total dihasilkan 330 merupakan Combined Cycle menggunakan binary power plant untuk memaksimalkan energi ada. Keluaran Steam Turbine Generator ...

Antiferromagnetically coupled Mn(III)Mn(IV) dimers have been commonly used to study biological systems that exhibit complex exchange interactions. Such is the case for the oxygen evolving complex (OEC) in photosystem II (PSII), where we have studied whether the C-terminal carboxylate of D1-Ala344 is directly bound to the Mn cluster. To probe these protein-derived carboxylate hyperfine interacti...

Let Rα be the Riesz distribution on a simple Euclidean Jordan algebra, parametrized by α ∈ C. I give an elementary proof of the necessary and sufficient condition for Rα to be a locally finite complex measure (= complex Radon measure). Soit Rα la distribution de Riesz sur une algèbre de Jordan euclidienne simple, paramétrisée par α ∈ C. Je donne une démonstration élémentaire de la condition néc...
