The spectral characterization of quantum emitter luminescence over broad wavelength ranges and fast time scales is important for applications ranging from biophysics to quantum technologies. Here we present the application of time-domain Fourier transform spectroscopy, based on a compact and stable birefringent interferometer coupled to low-dark-count superconducting single-photon detectors, to the study of quantum emitters. We experimentally demonstrate that the system enables spectroscopy of quantum emitters over a broad wavelength interval from the near-infrared to the telecom range, where grating-based spectrometers coupled to InGaAs cameras are typically noisy and inefficient. We further show that the high temporal resolution of single-photon detectors, which can be of the order of tens of picoseconds, enables the monitoring of spin-dependent spectral changes on sub-nanosecond time scales.

Objetivo: descrever o conhecimento da equipe enfermagem no processo de inserção e a manutenção do PICC em neonatos. Método: estudo de caráter descritivo e exploratório de caráter quantitativo realizado em uma UTI Neonatal de um hospital do município de Foz do Iguaçu-PR, de julho a setembro de 2019. Fizeram parte do estudo 25 profissionais da enfermagem. A coleta de dados se deu por meio de um instrumento estruturado de coleta de dados. Resultado: Participaram da amostra 25 profissionais da enfermagem, sendo 21 técnicos de enfermagem e 4 enfermeiros. Pelos resultados, percebe-se que as profissionais conhecem sobre a PICC e que sabem manipular de forma adequada. Conclusão: Apesar da equipe de enfermagem estar capacitados para utilização do PICC, ainda mostram algumas inseguranças em relação ao mesmo. Considera-se que elas podem ser sanadas durante as praticas de educação permanente, pela obrigação da educação continuada.

The role of heat and mass transfer in moving fluid is important in view of several physical problems such as those dealing with chemical reactions and those encountered with dissociating fluids. A lot of interest has been built in the study of the flow of heat and mass transfer. The aim of present investigation was to study the effects of heat and mass transfer on steady hydromagnetic boundary layer flow over an impermeable horizontal surface with ohmic and viscous heat dissipation. The model formulated taking into consideration the viscous energy dissipation. The surface is assumed to be impermeable. The governing equations formulated based on the conservation of momentum, species and energy were considered in steady state form and solved analytically using direct integration. The results obtained are presented graphically and discussed. The results revealed the effects of operating parameters on the flow and heat transfer over an impermeable surface. Our findings showed that there is a continuous increase in fluid velocity and a decrease in medium temperature along the distance while fluid velocity decreases and medium temperature increases as values of magnetic parameter and Reynolds number increases. These results might be used for interpretation or experiments planning of the more complex flow and heat transfer processes.

Problem-based learning (PBL) is one of teaching methods adopted by the Faculty of Medicine, University of AL-Butana; whereas the students form a complementary part to the learning process. This approach helps the students to have an active engagement and participation through research, discussion and exchange of information. This is across sectional descriptive study which was conducted at the Faculty of Medicine, University of AL-Butana from February up to October 2021. This study aimed to assessing undergraduate medical students’ perception to PBL in the clinical phase of circular in Faculty of Medicine University of Al-Butana (FMUB) at batches sex and five. All students in batch five and six their number were 140 at the clinical phase of the curriculum were enrolled in the study. Structural questionnaire was designed to collecting data. The results of study presented that the majority of the students were considered that the PBL were effective in construction of professional knowledge. The study showed that the variety of the PBL presented in the curriculum in the clinical phase were not adequately enough, also the students were highly satisfied with their tutor’s performance. The study concluded that PBL were effective in construction of professional knowledge and students were highly satisfied with their tutors’ performance. The study recommended that the adoption of the PBL as an instructional methods of the medical students of the Faculty of Medicine at University of AL-Butana.

Background: This article continues a series of studies devoted to ludic competence/playfulness and one of its components is flirting. The aim of the study: in the context of parametric concept of meaning, to identify on the basis of applied psycholinguistic research the semantic components of the stimulus “flirting person”, which are actualized in the speech acts of Russian-speaking inhabitants of Ukraine. Material and Methods: The main method of the research is a psycholinguistic experiment whose major stage is the controlled association experiment with the stimulus “flirting person”. The sample comprised 215 young people (aged 21-35), of which 112 females and 103 males. Results: At the final stage of formulation of the instructions 23 semantic features were selected for the stimulus “flirting person”. The results of the controlled association experiment with the stimulus “flirting person” allowed to build 23 associative fields and obtain the material for describing the behaviour pattern of ludic position Diplomat (flirting person) reflecting the reality of linguistic consciousness of young Russian-speaking inhabitants of Ukraine. Conclusions: Cluster analysis of the associative field of the semantic feature “What is the person’s marital status?” allowed to define: three core clusters – “Free” (71.16%), “In a relationship” (14.42%), “Any” (3.72%); three peripheral clusters – “Qualities” (3.26%), “Emotional State” (3.26)%, “Role in family relations” (1.40%); extreme peripheral clusters – “Changeable” (0.93%); an isolated female reaction “Guy” suggests an ambiguous interpretation and allows to highlight different meanings – “Gender” and “Age”.

Biodiversity informatics depends on digital access to credible information about species. Many online resources host species' data, but the lack of categorisation for these resources inhibits the growth of this entire field. To explore possible solutions, we examined the (now retired) Biodiversity Information Projects of the World (BIPW) dataset created by the Biodiversity Information Standards (TDWG); this project, which ran from 2007-2015 (officially removed from the TDWG website in 2018) was an attempt at organising the Web's biodiversity databases into an indexed list. To do this, we applied a simple classification scheme to score databases within BIPW based on nine data categories, to characterise trends and current compositions of this biodiversity e-infrastructure. Primarily, we found that of 600 databases investigated from BIPW, only 315 (~53%) were accessible at the time of this writing, underscoring the precarious nature of the biodiversity information landscape. Many of these databases are still available, but suffer accessibility issues such as link rot, thus putting the information they contain in danger of being lost. We propose that a community-driven database of biodiversity databases with an accompanying ontology could facilitate efficient discovery of relevant biodiversity databases and support smaller databases – which have the greatest risk of being lost.
