1. Effect of seasons on delirium in postoperative critically ill patients: a retrospective analysis
Abstract Background and objectives Postoperative delirium is common in critically ill patients and is known to have several predisposing and precipitating factors. Seasonality affects cognitive function which has a more dysfunctional pattern during winter. We, therefore, aimed to test whether seasonal variation is associated with the occurrence of delirium

2. 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

3. A Parametric Study of Inductive SWIPT Systems Assisted by Metamaterial Using Virtual Magnetic TL-Based Channel Modeling
Abstract This paper presents a general methodology based on the description of the inductive channel as virtual magnetic transmission-lines (VMGTLs). In comparison with other existing methods, VMGTL approach presents a better physical insight of the channel behavior since the model correctly preserves the energy flow between the transmitting and receiving co

4. Psychometric properties the of Brazilian Portuguese version of Snaith-Hamilton Pleasure Scale (SHAPS)
Abstract Introduction Anhedonia is defined as the reduced ability to feel pleasure and is a core symptom of various psychiatric disorders such as depression and schizophrenia. The Snaith-Hamilton Pleasure Scale (SHAPS) was developed to assess the presence of anhedonia. The objective of this study was to assess the psychometric properties of the Brazilian P

5. Lipoprotein(a) levels in children and adolescents: Ouro Preto Study
Abstract Background Lipoprotein (a) is a cardiovascular risk factor in adult. Studies have shown the presence of this emergent risk factor in school children, which may contribute to the development of atherosclerosis in adulthood. Objective To evaluate the association between lipoprotein (a) and cardiovascular risk factors in school children. Methods Lip

6. SUBJECT ELLIPSIS IN EARLY CHILD LANGUAGE
Abstract This paper aims to discuss whether parametric analyses can account for missing subjects in child English. I review previous parametric analyses of missing subjects and present a new learning model built upon a more recent version of the Null Subject Parameter (Holmberg, 2010a). Parametric analyses of the phenomenon have the advantage of giving a sim

7. Body composition, but not insulin resistance, influences postprandial lipemia in patients with Turner's syndrome
ABSTRACT Objective: The aim of the present study was to examine the influence of body composition and insulin resistance on the magnitude of postprandial lipemia in patients with Turner's syndrome receiving oral versus transdermal estrogen replacement. Subjects and methods: Twenty-five patients with Turner's syndrome receiving oral or transdermal estrogen

8. Bearing failure in bolted sleeve connections with circular hollow sections under compression
Abstract This article analyzes sleeve connections between circular hollow sections. This type of connection is composed of two tubes connected by bolts to an inner tube with a smaller diameter, and explores the efficiency, aesthetics and resistance of hollow sections subjected to tension and compression. In previous researches, sleeve connections with aligne

9. Physics-Based Design of Microstrip Magnetic Dipoles Using Cavity Model
Abstract This paper presents an efficient technique of microstrip magnetic dipoles design that explores the physics ruling the antenna behavior not restricting to parametric analyses in a full-wave simulation software. The proposed approach makes use of the cavity model whose parameters are progressively enhanced by using full-wave electromagnetic simulation

11. Pricing Crop Revenue Insurance Using Parametric Copulas
Resumo Nos últimos anos, o seguro de faturamento agrícola tem sido amplamente discutido. Este tipo de seguro tornou-se um mecanismo importante para o gerenciamento dos riscos climáticos (afetam a produtividade) e de mercado (preços das culturas). No entanto, um estudo mais abrangente é necessário para investigar a estrutura de dependência entre as var

12. Growth curves of meat-producing mammals by von Bertalanffy’s model
Resumo: O objetivo desde trabalho foi avaliar como a parametrização e a aplicação de diferentes valores alométricos afetam a obtenção do ajuste mais adequado do modelo de von Bertalanffy, na descrição da curva de crescimento de mamíferos produtores de carne (bovinos, porcos, coelhos e ovelhas). Entre os modelos não lineares, o de von Bertalanffy t
