1. Synthesis and Evaluation of the Fungal Activity of New Pyrazole-Carboxamides against Colletotrichum gloeosporioides
The pyrazole core has been recognized by their biological properties and included in the synthesis of modern agrochemicals. Part of these studies consists of making structural modifications to pesticides for commercial purposes to increase efficacy. In this article, we present the synthesis of four new pyrazol-4-carboxamide 8a-8d derivatives (PCD), through a

2. MANNGA: A Robust Method for Gap Filling Meteorological Data
Resumo Este trabalho apresenta o método Mannga (Multiple variables with Artificial Neural Network and Genetic Algorithm), desenvolvido para preencher falhas em dados meteorológicos. A ideia principal é preencher as falhas baseando-se nos valores de outras variáveis meteorológicas medidas no mesmo momento, uma vez que as variáveis meteorológicas possue

3. Old tools as new support for on farm conservation of different types of maize
ABSTRACT: A germplasm collection should represent the diversity of the target species and the gene pools associated with it. However, it is critical to establish collection plans which ensure such representativeness. At times it is difficult to identify the best strategy for collecting domesticated species that are conserved in situ/on farm, since, in genera

4. Can expressed prostatic secretions affect prostate biopsy decision of urologist?
ABSTRACT Objectives: To evaluate the frequency of NIH category IV prostatitis, and the use of expressed prostatic secretions tests in an effort to improve the reliability of prostate specific antigen as an indicator, to avoid unnecessary prostate biopsy. Materials and Methods: 178 expressed prostatic secretion positive patients with serum prostate specific

5. Effects of Amount of Glass Fiber Laminate Skins in Sandwich Composite of Filled Core
The purpose of this work is the study of the mechanical behavior of two different sandwich composite in static and fatigue analysis of three-point bending, using different amount of glass fiber laminated as skins, remaining with same total thickness. The specimens are composed of glass fiber cloth and epoxy resin. The static tests provided the mechanical pro

6. Pure and Decorative Plywood Panels from Cordia trichotoma and Grevillea robusta
ABSTRACT The objective of this study was to evaluate the technical viability of Cordia trichotoma and Grevillea robusta wood for the production of plywood panels, as well as to verify the behavior of these species in combination with Pinus taeda and Eucalyptus saligna. Panels were produced using veneers of each species and in combination, totaling 8 treatme

7. Influence of remaining coronal thickness and height on biomechanical behavior of endodontically treated teeth: survival rates, load to fracture and finite element analysis
Abstract Objective To evaluate the effect of restorative strategy (fiber post vs cast post and core), coronal height (0 mm vs 2 mm) and thickness (higher than 1 mm vs lower than 1 mm) on survival rate, fracture resistance and stress distribution. Material and Methods Seventy-two bovine teeth were cleaned and allocated in six groups (n = 12). Twenty-four te

8. ILITIA: telehealth architecture for high-risk gestation classification
Abstract Introduction According to the World Health Organization, about 9.2% of the 28 million newborns worldwide are stillborn. Besides, about 358,000 women died due to complications related to pregnancy in 2015. Part of these deaths could have been avoided with improving prenatal care agility to recognize problems during pregnancy. Based on that, many eff

9. Differential Scanning Calorimetry study on curing kinetics of diglycidyl ether of bisphenol A with amine curing agents for self-healing systems
ABSTRACT Epoxy resin is one of the most important polymeric matrixes for diverse uses, such as aeronautical, mobile, electronics and others. Providing a material capable of self-healing microcracks will allow it to have a more reliable and longer use. In order to study this new property of self-healing to an epoxy resin, a Differential Scanning Calorimetry (

10. Catechol-O-methyltransferase (COMT) polymorphisms modulate working memory in individuals with schizophrenia and healthy controls
Objective: Cognitive impairment is a core feature of schizophrenia, related to dopaminergic dysfunction in the prefrontal cortex (PFC). It is hypothesized that functional single nucleotide polymorphism (SNP) rs4680 of the catechol-O-methyltransferase (COMT) gene could mediate the relationship between cognition and dopamine activity in the PFC. Other COMT SN

11. Estimation of Three-Phase Induction Motor Equivalent Circuit Parameters from Manufacturer Catalog Data
Abstract The single phase equivalent circuit is largely used to model the three-phase induction motors in steady-state operation and under sinusoidal balanced voltages. Depending on the desired application, the circuit may or may not represent core losses, a double cage or even the variation of parameters due to skin effect and saturation. However, the deter

12. The Response of Clamped Shallow Sandwich Arches with Metallic Foam Cores to Projectile Impact Loading
Abstract The dynamic response and energy absorption capabilities of clamped shallow sandwich arches with aluminum foam core were numerically investigated by impacting the arches at mid-span with metallic foam projectiles. The typical deformation modes, deflection response, and core compression of sandwich arches obtained from the tests were used to validate
