Asymmetrical bloch branes and the hierarchy problem

We investigate a two scalar fields split braneworld model which leads to a possible approach to the hierarchy problem within the thick brane scenario. The model exhibits a resulting asymmetric warp factor suitable for this purpose. The solution is obtained by means of the orbit equation approach for a specific value of one of the parameters. Besides, we analyze the model qualitative behaviour for arbitrary parameters by inspecting the underlying dynamical system defined by the equations which give rise to the braneworld model. We finalize commenting on the metric fluctuation and stability issues.Comment: 8 pages, 7 figure

New Algorithms for Computing a Single Component of the Discrete Fourier Transform

This paper introduces the theory and hardware implementation of two new algorithms for computing a single component of the discrete Fourier transform. In terms of multiplicative complexity, both algorithms are more efficient, in general, than the well known Goertzel Algorithm.Comment: 4 pages, 3 figures, 1 table.

COMPASSION IN TIMES OF COVID-19 PANDEMIC

Objetivo: Refletir sobre a compaixão em tempos de pandemia de COVID-19. Métodos: Estudo do tipo revisão narrativa tendo como base a estrutura de um ensaio teórico reflexivo que visa contribuir com discussões sobre a compaixão e sobre como ela vem sendo manifestada diante do atual cenário de pandemia. Resultados e discussão: A partir dessa reflexão foi possível observar que a pandemia de COVID-19 tem aflorado discussões acerca da importância da compaixão, a partir do momento em que os profissionais da saúde se sentem sensibilizados diante o sofrimento dos pacientes e do distanciamento destes dos seus familiares. Assim, espera-se com essa reflexão incentivar a prática de atitudes compassivas no meio social, nos ambientes de cuidados aos pacientes com COVID-19, e reforçar sua importância como qualidade altruísta dos profissionais da saúde, com enfoque para aqueles do campo da enfermagem, considerando sua presença constante nos cuidados aos pacientes hospitalizados e diagnosticados com COVID-19. Considerações finais: Conhecer, refletir e discutir a compaixão que deve ser uma prática diária diante de momentos tão difíceis que tem sido vivenciado, de modo a contribuir para que a sociedade e equipes de saúde demostrem toda sua sensibilidade compassiva consigo e com o outro, não somente durante a pandemia, mas para além dela.Aim: To reflect on compassion in times of the COVID-19 pandemic. Methods: A narrative review study based on the structure of a reflective theoretical essay that aims to contribute to discussions about compassion and how it has manifested in the current pandemic scenario. Results and discussion: From this reflection, it was possible to observe that the COVID-19 pandemic has created discussions about the importance of compassion, this is from the moment that health professionals feel and understand the suffering of patients and then their distancing from these patients – who could be your family members. Thus, this reflection is expected to encourage the practice of compassionate attitudes in the social environment, in the care environments for patients with COVID-19, and to reinforce its importance as an altruistic quality of health professionals, particularly those with a focus in the field of nursing, considering its constancy in the care of hospitalized patients diagnosed with COVID-19. Final considerations: Knowing, reflecting and discussing compassion must become a daily practice for health professionals when faced with such difficulties, in order to contribute to society in general, and for health teams to demonstrate their compassion and sensitivity towards themselves and others, not only during the pandemic, but beyond it

Bus Robberies in Belo Horizonte, Brazil: Solutions for Safe Travel

This study examines the spatial patterns and other situational determinants leading to the high number of bus robberies in Belo Horizonte. Main research questions include patterns of robberies, spatial concentration, locations prone to robberies, and environmental characteristics therein. This study also provides a variety of safety measures based on the Situational Crime Prevention approach. The Rapid Assessment Methodology (RAM) was employed using both quantitative and qualitative data. It involves spatial analysis, direct observation of hot spots using a safety audit protocol, and focus group discussions with key participants. Bus robberies involve minimum risk and low detection and arrest. The “hottest products” to be stolen include electronic devices and cash. The robberies occur at specific times and locations depending on opportunity. As many crimes go unreported, police data have inaccuracies. Therefore, it is impossible to verify the exact location of the robberies. This study concludes that for safe travel preventive measure should focus on reducing crime opportunities. A collaborative effort is needed from agencies and individuals alike. Further research should focus on examining why the majority of bus robberies are concentrated in only two main bus routes. Are these hot spots just recent spikes or are they chronic

Propagation of yellow mombin by stem and root cuttings treated with indolebutyric acid

Yellow mombin is a fruit species of growing interest in the agro-industrial sector, mainly in the North and Northeast regions of Brazil, although its commercial exploitation is still limited due to the lack of information regarding its propagation, among other factors. In this perspective, this work aimed to study the effect of the application of indolebutyric acid (IBA) in the vegetative propagation of yellow mombin by stem and root cuttings. The experiments were conducted in a plant nursery, under a completely randomized experimental design consisting of six concentrations of IBA (0, 1000, 2000, 3000, 4000 and 5000 mg.kg-1 in industrial talc), four replications, and ten cuttings per plot. The stem cutting experiment also evaluated the effect of the types of cuttings (tanchan, basal, stratified basal, medial, and apical), with the material being collected from a yellow mombin tree in full vegetative growth. The root cuttings were collected from a matrix plant in the stage of vegetative rest and cut into 15 cm length segments. After 120 days, the following variables were evaluated: percentage of living, sprouted, rooted, and calloused cuttings, and dry mass of roots and sprouts. The cuttings of the tanchan type showed higher survival and sprouting percentages, regardless of the concentration of IBA applied, whereas the rooting rate was low. The application of IBA increased the rooting percentage of the root cuttings until the maximum concentration of 5000 mg.kg-1, reaching 77.5%, although it did not influence the other variables analyzed. The root cuttings of yellow mombin exhibit good regeneration capacity.Yellow mombin is a fruit species of growing interest in the agro-industrial sector, mainly in the North and Northeast regions of Brazil, although its commercial exploitation is still limited due to the lack of information regarding its propagation, among other factors.
