SDCS quantum mechanical flux formula revisited for electron-hydrogen ionization
(Global Science Press, 2013-08)
Through a simple, classical, energy conservation analysis, we propose a fi-<br />nite distance reinterpretation of the standard energy fraction definition used for the electron-hydrogen S wave ionization process. The energy ...
Meteorite impacts in the ocean: the danger of tsunamis on the coast of Buenos Aires Province, Argentina
(Springer, 2020-07)
Comets, meteorites, or asteroids impacting against the Earth are not unusual events. Such impacts on the ocean could produce tsunamis which can reach coastal areas. This paper aimed to analyze the tsunami wave heights on ...
Análise e comparação de técnicas de controle para aumento da eficiência energética de motores de indução trifásicos
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2016-12-13)
This research presents an analysis and comparison of control techniques that aim at increasing energy efficiency on driving three-phase induction motors. First, electrical and mechanical modeling of the induction machine ...
A short-term assessment of carbon dioxide fluxes under contrasting agricultural and soil management practices in Zimbabwe
(Canadian Center of Science and Education, 2015)
Soil fauna community and ecosystem's resilience: A food web approach
(Elsevier Masson, 2019-08)
There is an increasing concern for the conservation of soil biodiversity and its ecosystem functions. In this context, it is crucial to comprehend the typical response times of the community (meso and macrofauna) to ...
Energy Balance In The Cerrado Of Ecological Station Of Assis - Assis, Sao Paulo State, Brazil
(UNIV ESTADUAL MARINGA, PRO-REITORIA PESQUISA POS-GRADUACAOMARINGA, 2015)
Energy balance in the Cerrado of Ecological Station of Assis - Assis, Sao Paulo State, Brazil
(Univ Estadual Maringa, Pro-reitoria Pesquisa Pos-graduacao, 2015-01-01)
This article presents the results of the net radiation partitioning (Rn) between latent heat (LE) and sensible heat fluxes (H) and its relationship with water availability (rain) in an area with Cerrado vegetation in the ...
Causes and Consequences of Magnetic Cloud Expansion
(EDP Sciences, 2009-12)
Context. A magnetic cloud (MC) is a magnetic flux rope in the solar wind (SW), Which, at 1 AU, is observed ∼2–5 days after its expulsion from the Sun. The associated solar eruption is observed as a coronal mass ejection ...
Effect of surface material properties and operating conditions on the heat flux and temperature distributions in the cavity receiver of a solar-dish-coupled biomass gasification reactor
(Elsevier, 2021-09)
In this paper, a new 5.8 kW solar biomass gasification reactor is modeled by means of Monte-Carlo ray-tracing method and computational fluid dynamics. The reactor is coupled to the cylindrical cavity receiver of a ...
