Effects on Light Efficiency in Discharge and Solid-State Lighting Operation, Supplied by No-Sinusoidal Voltage
(Ieee-inst Electrical Electronics Engineers Inc, 2016-05-01)
The widespread use of discharge lamps and solid-state lighting is justified by its high-energy efficiency. However, the massive use causes degradation of power quality provided. In this context, the objective was the ...
The J/ψΦ decay channel of the Y(4140) Molecular State
(2015-01-01)
Using the QCD sum rule approach we study the Y(4140) state assuming that it can be described by a D* sD* s molecular state with JPC = 0++ quantum numbers. We evaluate the decay width into the channel Y J/ψΦ and we find the ...
The relative importance of total factor productivity and factors of production in income per worker: evidence from the brazilian states
(Universidade Federal de Minas GeraisBrasilFCE - DEPARTAMENTO DE CIÊNCIAS ECONÔMICASUFMG, 2016)
O diferencial de renda por trabalhador em diferentes regiões do Brasil é impressionante. Para avaliar a importância relativa dosfatores de produc¸ão e da produtividade total dos fatores (PTF) na disparidade de renda por ...
Assessment of the efficiency of a trophic state index in determining the water quality of public water supply reservoirs
(Assoc Brasileira Engenharia Sanitaria Ambiental, 2018-07-01)
The aim of this study consists in the evaluation of the trophic state index (IET) efficacy as a tool in the water quality analysis of three reservoirs. The IET was calculated based on water transparency in the reservoir ...
A result on the total colouring of powers of cycles

The limits of the extended Huckel theory to calculate the total density of states of medium-sized molecules
(SOCIEDAD CHILENA DE QUIMICA, 2006-12)
Two medium-sized molecular systems X-60 (X=C,N) were analyzed using Extended Huckel, Density Functional and ab initio Hartree-Fock methods. The aim of the work was to test the reliability of the EHT methodology to calculate ...
An Estimate of Unidentified and Total U.S. Coronavirus Cases by State on April 21, 2020
(Universidad EAFITEscuela de Economía y Finanzas, 2020-04-23)
I use data on cumulative tests, positive tests, and deaths for the coronavirus in South Korea and the U.S. lower-48 states during April 2020 to estimate the extent of infection and the unidentified share of the infected ...
Solid-state bioprocessing of sugarcane bagasse with Auricularia fuscosuccinea for phenolic compounds extraction
(Taylor & Francis, 2021-10)
Sugarcane bagasse is a natural source of phenolic compounds. However, these compounds are bound to lignocellulose components, reducing their ability to function as good antioxidants. These linkages are hydrolyzed by enzymes ...
Total deposition of anions and metals: An indicator of sugarcane burning impact, in the são josé do rio preto town, são paulo state, Brazil
(2010-01-01)
Air pollution is not a recent issue and has become a serious environmental problem affecting human health, urban life quality and, sustainability of urban ecosystems. São José do Rio Preto (SJRP) is a city with around ...
A neural network estimator for total biomass of filamentous fungi growing on two dimensional solid substrate
(KLUWER ACADEMIC PUBL, 1998)
A neural network dynamic model is proposed for the on-line estimation of total biomass during filamentous fungi cultures on two dimensional solid substrate. The neural network provides an accurate and robust estimation of ...
