1. In silico Evaluation of Cucurbit[6]uril as a Potential Detector for Cocaine and Its Adulterants Lidocaine, Caffeine, and Procaine
Illicit drugs and their trafficking require worldwide efforts in investigation, detection, and control. Colorimetric tests are often applied to identify drugs. Cocaine has some well-known adulterants that can provide a false positive response. Cucurbit[6]uril (CB[6]) has been suggested as a potential detector for cocaine and other illicit drugs. This work us

2. Forecasting bearing capacity performance with semi-empirical and theoretical methods applied to precast concrete piles founded on sandy clay in the region of Uberlândia-MG, Brazil
Abstract This article presents a study on the performance of semi-empirical methods based on the Standard Penetration Test (SPT) for the prediction of bearing capacity already disseminated in the practice of Brazilian Foundation Engineering (Aoki and Velloso, 1975; Décourt and Quaresma, 1978, 1996; Teixeira,1996), together with the recent method proposed by

4. Contenidos de cultura en las prácticas docentes y pedagógicas de lenguas extranjeras (PLE y ELE)
RESUMO Atualmente tem se estendido uma posição teórica e prática que concebe o ensino da língua como parte de um processo cultural que leva as aulas de português (PLE) e espanhol (ELE) como língua estrangeiras a incorporarem aspectos da cultura da língua alvo. Partimos de uma concepção socioantropológica de cultura e nos propomos conhecer o uso qu

5. Actual evapotranspiration and crop coefficient of sweet orange during the initial development phase in the Rio Largo region, Alagoas
RESUMO: A determinação da evapotranspiração real da cultura (ETa) é importante para o manejo da irrigação. Os principais métodos e modelos físicos de estimativa da ETa requerem dados que não são facilmente disponíveis. Neste trabalho, obteve-se o coeficiente da cultura (Kc) da laranja lima na fase inicial de desenvolvimento e avaliou-se o desemp

6. Towards post-colonial capacity-building methodologies – some remarks on the experiences of health researchers from Mozambique and Angola
Resumo Este artigo analisa dispositivos de capacitação na prática, explorando as expetativas, os imaginários e as experiências de pesquisadores de saúde de Moçambique e Angola. Os dados empíricos resultam do projeto “University Development and Innovation – Africa (UDI-A)”, financiado pelo programa Erasmus+, um consórcio estabelecido entre inst

7. Water-Soluble Benzazole Dyes Fluorescent by ESIPT: Structural Characterization, Photophysical Properties and Its Application as a Probe for Direct Staining of Helminths
A series of four water-soluble benzazole dyes that emit fluorescence by the excited state intramolecular proton transfer (ESIPT) mechanism were structurally characterized by Fourier transform infrared spectroscopy (FTIR), 1H and 13C nuclear magnetic resonance (NMR) attached proton test (APT) and mass spectrometry. Their photophysical properties were systemat

8. Evaluación de caminos de difusión de Al en UAl4
ABSTRACT Once the stable structure of point defects and concentrations of defects in thermal equilibrium were obtained for each composition of Al of the compound UAl4, we identified, in this work, the more likely mechanisms for Al mobility in UAl4, and we analyzed transition states in the diffusion of Al in UAl4 by the Nudged Elastic Band (NEB) method implem

10. Medicalización más allá de los médicos: marketing farmacéutico en torno al trastorno por déficit de atención e hiperactividad en Argentina y Brasil (1998-2014)
Abstract From a critical analysis of medicalization studies, and as a contribution to these perspectives, we describe and analyze the ways in which the transnational pharmaceutical industry penetrates diverse social spaces, with different marketing strategies, to consolidate medicalized processes in Argentina and Brazil. We analyzed two expansion methods of

11. Hockey Stick Phenomenon: Supply Chain Management Challenge in Brazil
The objective of this study is to investigate a phenomenon that occurs in Brazil, specifically the spike in demand at the end of the sales period, known as the hockey stick phenomenon. This analysis will encompass the causes as well as the impacts of this phenomenon, in a way that allows alternative policies to be evaluated. Data was collected from a Brazili

12. Unified method for the prediction of rain attenuation in satellite and terrestrial links
In this paper, a semi-empirical method for the prediction of rain attenuation in slant paths and terrestrial links is proposed. The method uses the same simplified model of equivalent rain cell that is the basis for the ITU-R rain attenuation prediction methods but, additionally, the concept of an effective rain rate is introduced. This allows the use of the
