The spin-averaged binding energy and the hyperfine mass splitting of heavy-light mesons are investigated within the constituent quark model as a function of the inverse heavy-quark mass. It is shown that the so-called heavy-quark kinetic energy, −λ1/2mQ, may differ remarkably from the non-relativistic expectation 〈p〉/2mQ, thanks to relativistic effects in the effective interquark potential for ...

This study was carried out to investigate the effect of differentpreservative solutions to improve the keeping quality of tuberose (Polianthes tuberosa cv. Single). These preservative solutions (treatments) were: T1= 2% sucrose + 200 mg/l AgNO3, T2= 2% sucrose + 200 mg/l AgNO3 + 25 mg/l citric acid, T3= 2% sucrose + 300 mg/l HQS, T4 = 2% sucrose + 300 mg/l HQS+ 25 mg/l citric acid, T5= 2% sucro...

Metodologicamente, realizou-se uma pesquisa participante, abordagem qualitativa. Os result...

Objetivo: este trabalho busca descrever a utilização de histórias em quadrinhos (HQs) sobre temas relacionados à pandemia Covid-19, como meio divulgação científica nas redes sociais, facebook e instagram da Casa Descoberta (CD), um centro Universidade Federal Fluminense. Metodologia: Inicialmente elaborou-se questionário diagnóstico para perceber os Química Ciência com Covid-19 que o público ge...

Risk assessments are generally based on exposures predicted by use of simple models of accumulation from abiotic compartments or the diet. The use of tissue-specific measurements of residue concentrations in wildlife tissues is more accurate and subject to less uncertainty, but these data are often not available. This report compares the results of two different site-specific approaches for ass...

The drag and diffusion coefficients of heavy quarks propagating through quark–gluon plasma (QGP) have been estimated by shielding the infra-red divergences using electric magnetic screening masses. electric-type in perturbative quantum chromodynamics (pQCD) has widely studied used evaluating coefficient (HQs). impact on HQs is not before to best our knowledge. We explore effect mass found it be...

Apresentamos experiência de uso Histórias em Quadrinhos (HQs) como facilitadoras do Ensino História e Artes com a temática escolar sobre o Patrimônio Histórico no colégio Imaculado Coração Maria na cidade Olinda Pernambuco. A pesquisa abordou conceito representação cultural através uma atividade pedagógica que envolveu criação HQs pelos estudantes, usando linguagem dos quadrinhos potencializado...

A study was conducted to test the effect of 58.5 mM maltose, glucose, fructose, galactose and sucrose, and sucrose concentrations of 14.6, 29.2, 58.5 and 117.0 mM supplemented with 200 mg L-1 8-hydroxyquinoline sulphate (HQS) on the vase life and stem fresh weight changes in waxflower (Chamelaucium Desf.). The effect of the interaction between sucrose and HQS concentrations on the vase life of ...

Researchers at the University of Massachusetts quantified dermal, airborne and Dislodgeable Foliar Residues (DFR) of three reduced risk pesticides, azoxystrobin, carfentrazone-ethyl, and halofenozide. Dosimetry techniques were used to assess the exposure of volunteer golfers to these pesticides under worst-case scenarios during the play of 32 rounds of simulated golf. All exposures resulted in ...
