1. Performance of the Pandemic Medical Early Warning Score (PMEWS), Simple Triage Scoring System (STSS) and Confusion, Uremia, Respiratory rate, Blood pressure and age ≥ 65 (CURB-65) score among patients with COVID-19 pneumonia in an emergency department triage setting: a retrospective study
ABSTRACT BACKGROUND: Healthcare institutions are confronted with large numbers of patient admissions during large-scale or long-term public health emergencies like pandemics. Appropriate and effective triage is needed for effective resource use. OBJECTIVES: To evaluate the effectiveness of the Pandemic Medical Early Warning Score (PMEWS), Simple Triage S

2. Estudos numéricos da formação e dinâmica de defeitos topológicos em cristais líquidos nemáticos
Neste trabalho estudamos numericamente a formação e dinâmica de defeitos topológicos em cristais líquidos nemáticos. Nosso estudo é baseado no modelo de Ginzburg- Landau, o qual descreve a evolução da ordem orientacional de um cristal líquido em termos de um tensor de segunda ordem simétrico e com traço nulo. Este modelo fenomenológico permite e

3. Beauveria bassiana: quercetinase production and genetic diversity
Beauveria bassiana genetic diversity and ability to synthesize quercetin 2,3-dioxygenase (quercetinase) were analyzed. B. bassiana isolates, obtained from Brazilian soil samples, produced quercetinase after induction using 0.5 g/L quercetin. B. bassiana ATCC 7159 (29.6 nmol/mL/min) and isolate IP 11 (27.5 nmol/ml/min) showed the best performances and IP 3a (

4. Indices of movement behaviour: conceptual background, effects of scale and location errors
A fundamental step in the emerging Movement Theory is the description of movement paths, and the identification of its proximate and ultimate drivers. The most common characteristic used to describe and analyze movement paths is its tortuosity, and a variety of tortuosity indices have been proposed in different theoretical or empirical contexts. Here we revi

5. Contributions towards building a biosocial model of leadership: testosterone, digit ratio and locus of control / Contribuições para a construção de um modelo biossocial de liderança: testosterona, relação digital e lócus de controle
The current research investigated the relationship of some leadership behaviors, thereafter called Executive Leadership, with the concentration levels of testosterone found in the human saliva. The research also investigated the corelations among Executive Leadership behaviors, the digital ratio (2nd:4th) and the concept of internal Locus of Control. The dig

6. The carreau-yasuda fluids: a skin friction equation for turbulent flow in pipes and kolmogorov dissipative scales
In this work the turbulent flow of the Non-Newtonian Carreau-Yasuda fluid will be studied. A skin friction equation for the turbulent flow of Carreau-Yasuda fluids will be derived assuming a logarithmic behavior of the turbulent mean velocity for the near wall flow out of the viscous sub layer. An alternative near wall characteristic length scale which takes

7. Scale dependence in earthquake phenomena and its relevance to earthquake prediction.
The recent discovery of a low-velocity, low-Q zone with a width of 50-200 m reaching to the top of the ductile part of the crust, by observations on seismic guided waves trapped in the fault zone of the Landers earthquake of 1992, and its identification with the shear zone inferred from the distribution of tension cracks observed on the surface support the e

8. Cooperative chiral order in the B-Z transition in random sequences of DNA.
We present a theory for cooperative chiral order in the transition between right-handed B-DNA and left-handed Z-DNA. This theory, based on the random-field Ising model, predicts the characteristic length scale of Z-DNA segments. This length scale depends on whether the DNA is a homopolymer or a random sequence: it is approximately 4000 nucleotides in a homop

9. Gene Flow and Selection in a Cline
A model of the effect of gene flow and natural selection in a continuously distributed, infinite population is developed. Different patterns of spatial variation in selective pressures are considered, including a step change in the environment, a "pocket" in the environment and a periodically varying environment. Also, the problem of the effect of a geograph

10. Quantification of DNA Patchiness Using Long-Range Correlation Measures
We introduce and develop new techniques to quantify DNA patchiness, and to quantify characteristics of its mosaic structure. These techniques, which involve calculating two functions, α(l) and β(l), measure correlations at length scale l and detect distinct characteristic patch sizes embedded in scale-invariant patch size distributions. Using these new met

11. Characteristic length scale of the intermediate structure in zero-pressure-gradient boundary layer flow
In a turbulent boundary layer over a smooth flat plate with zero pressure gradient, the intermediate structure between the viscous sublayer and the free stream consists of two layers: one adjacent to the viscous sublayer and one adjacent to the free stream. When the level of turbulence in the free stream is low, the boundary between the two layers is sharp,

12. Five-fold symmetry in crystalline quasicrystal lattices
To demonstrate that crystallographic methods can be applied to index and interpret diffraction patterns from well-ordered quasicrystals that display non-crystallographic 5-fold symmetry, we have characterized the properties of a series of periodic two-dimensional lattices built from pentagons, called Fibonacci pentilings, which resemble aperiodic Penros
