Dirac Particles in Coulomb Like Field in FLRW–Space
Authors: Sharma S. K. , Dhungel P. R. , Khanal U. 
Published: February 2021

Behaviour of the Dirac particle in Coulomb like field in FLRW space is investigated. Firstly, the Maxwell equations, in terms of the vector potentials are solved to identify the Lorentz and Coulomb like gauges. The radial Coulomb like potential is solved in terms of Legendre functions. Then the Dirac equation is generalized to include this potential and the angular part is separated and solved. The radial and temporal parts of the mass less case is also separated and solved. But the massive case remains coupled. This is still reduced to the case where the Dirac particle can be represented as being in a combined gravitational and electric potential. This effective potential is found to develop an attractive well, which may require a revisit to the recombination era.

Published: February 2021

The low cost adsorbents were prepared from raw rice husk (RRH) and NaOH treated rice husk (NRH). Then prepared materials were characterized by XRD, FTIR and surface area of rice husk adsorbent were determined by methylene blue adsorption method. XRD showed amorphous nature with low crystallinity of the material. The FTIR spectra showed the presence of oxygenated functional groups such as ester, phenol, carbonyl and silica on the material. The surface area of RRH and NRH were found to be 387 and 417 m2/g respectively. Thus, prepared adsorbents were used for the removal of Fe(II) ion from aqueous solution. The influence of various parameters like pH, adsorbent doge, and contact time were studied for the better adsorption of Fe(II) on rice husk adsorbents. Results revealed that the maximum efficiency was achieved at pH 3 for Fe(II). The adsorption process was found to be best fitted to Langmuir adsorption isotherm model controlled by pseudo-second–order kinetics with the rate constant value i.e. 0.0218 and 0.0235 g/(mg·min) for RRH and NRH respectively. The χ2 values of pseudo second order was found to be lower which confirmed chemisorption, involving ion exchange and valence forces through sharing or exchange of electrons between adsorbent and adsorbate. The maximum adsorption capacity for Fe(II) on RRH and NRH was found to be 2.9 mg/g and 5.6 mg/g respectively. The positive ∆G value represents the randomness of the system during adsorption process. The slope of the linear plot of Qt vs t0.5 was linear but not passed through the origin, which indicates that, the intraparticle diffusion was not only rate controlling step. Temkin value showed the maximum binding energy (KT) for NRH was 16.4 L/g and for RRH it was 12.2 L/g.

Published: February 2021

This study aimed to determine the factors influencing Vietnamese tea export quantities, namely, the internal factors of national tea production, productivity, and cultivated areas, and the external factors of export price and world tea export quantity (excluding Vietnam). We employed a time-series linear model to estimate the magnitude as well as the sign of the aforementioned factors on Vietnam’s tea export quantity and two Box-Cox transformations called a simple back-transformed forecast and a bias-adjustment to forecast the growth rate of the Vietnamese tea export quantity until 2030. The results suggested that except for the total domestic tea production, all the proposed factors significantly affected the Vietnamese tea export quantity. The tea export quantity of other nations around the world had a significantly negative impact on Vietnamese tea that led to Vietnam’s tea exports dropping by 34 tons on average since the other countries exported 1,000 tons of tea. The forecasted outcome suggested an upward trend of Vietnamese tea exports up to 2030. In order to sustainably develop Vietnam’s tea industry, we recommend that the government should take supportive actions such as investing in in-depth tea processing to improve Vietnam’s tea export quality, focusing on post-harvest activities, investing in organic or high-value tea rather than conventional tea, continuing to accumulate land to support the growth of cultivated tea areas, and maintaining high productivity by using hybrid seeds.

Authors: Delmondes Fernanda Simão , Gutierrez Gabriela Mancia de , Imparato José Carlos Pettorossi , Raggio Daniela Prócida 
Published: February 2021

O freio labial superior é uma estrutura anatômica triangular que sofre alterações de forma, função e posição durante o desenvolvimento da criança. Um deslocamento para a porção mais apical cerca de 3 a 4 mm acima da gengiva marginal é esperado. Quando este não ocorre, ficando o freio inserido na papila incisiva, caracteriza-se uma anomalia de desenvolvimento chamada freio teto labial persistente. O momento e o tipo de intervenção nestas situações geram muita controvérsia; a avaliação de fatores como inserção baixa no rebordo alveolar, presença ou não de isquemia da papila palatina quando o freio é tracionado, presença de diastema interincisivos, dificuldade de higienização e/ou alimentação e retração gengival auxiliam na decisão de tratamento. Sendo assim, o objetivo deste trabalho foi apresentar 8 casos clínicos sobre abordagens de freio labial superior, discutindo diferentes momentos. Crianças de distintas idades foram avaliadas e submetidas às seguintes condutas: frenectomia, reposicionamento pela técnica de Chelotti ou acompanhamento clínico para posterior reavaliação. Concluiu-se que, apesar de existir uma indicação frequente de intervenção apenas após a erupção dos caninos superiores permanentes, existem outras situações em que uma abordagem precoce pode trazer mais benefícios ao paciente.
