1. Cascade Modeling of the Measuring System Used to Assess S-Parameters of Anchor Rods on Power Transmission Lines Guyed Towers
Abstract The structural condition of the cable-stayed towers anchorage on power transmission lines requires constant monitoring. Maintenance routines must be able to identify faulty anchor rods and substitute them to avoid tower collapses and power delivery interruptions. Modern statistical diagnostic systems based on machine learning requires the generation

2. Temporal trend in early sepsis in a very low birth weight infants' cohort: an opportunity for a rational antimicrobial use
Abstract Objective This study aimed to evaluate annual trends of early neonatal sepsis and antimicrobial use in very low birth weight infants for 12 years, as well as to identify microbiological agents, antimicrobial sensitivity profiles, and association with early neonatal death. Method This was a retrospective cohort study including 1254 very low birth w

3. Microstructural and mechanical characterisation of the Simon Bolivar's iron bridge structure, 19th century, Arequipa, Peru
Abstract The microstructure of the main structural elements (Phoenix columns, transversal beams and tie-rods) of the Simón Bolivar iron bridge, located in Arequipa (Peru), was investigated. The bridge was supposedly designed by Gustave Eiffel and opened to the public in 1882. The characterisation revealed that the columns, beams and tie-rods are made of pud

4. Proposal of a clinical score to stratify the risk of multidrug-resistant gram-negative rods bacteremia in cancer patients
ABSTRACT Introduction: Multidrug-resistant gram-negative rods (MDR GNR) represent a growing threat for patients with cancer. Our objective was to determine the characteristics of and risk factors for MDR GNR bacteremia in patients with cancer and to develop a clinical score to predict MDR GNR bacteremia. Material and Methods: Multicenter prospective study

5. Microwave Assisted Ultra-Fast Method to Synthesize Carbonate-Phosphates, Na3MCO3PO4 (M = Mn, Fe, Co, Ni) - Relevant Materials Applied in Sodium-Ion Batteries
Although largely used in mobiles and electric vehicles applications, insertion batteries based on Li-ion technology are high-cost devices. These applications require high-performance energy storage systems with high-energy and high-power densities, which are better attained by Li-ion technology. However, stationary applications such as power plants and unint

7. Influencia de la geometría del proyectil en ensayos dinámicos de tracción
ABSTRACT The focus of this study is to discuss the influence of the projectile’s length on the results of an experiment of the Hopkinson Traction Bar (SHTB). Simulations have been made by means of finite elements using the commercial software ABAQUS in tests of traction at high speeds of deformation in samples of aluminum alloy 7017T73 varying the length o

8. Aço carbono 1040 como indicador de agressividade do solo e da pasta de cimento em sistemas de ancoragem de linhas de transmissão
RESUMO O encapsulamento de hastes de âncora em pasta de cimento reduz o contato dos materiais metálicos com os ambientes agressivos, em torres estaiadas de linhas de transmissão de energia elétrica. Contudo, ainda são reportados casos de falha prematura devido à corrosão do sistema de ancoragem. O íon cloreto é considerado um dos principais respons�

9. Effect of Bulgarian propolis on the oral microflora in adolescents with plaque-induced gingivitis
ABSTRACT We compared the effect of two therapeutic approaches (marketed toothpaste and addition of Bulgarian propolis extract to the toothpaste) on gingival inflammation, plaque formation and oral microbial flora on Bulgarian adolescents with moderate plaque-induced gingivitis. The participants were divided randomly into two groups of 35 students. The first

11. Scaling of An Impacted Reticulated Dome Using Partial Similitude Method
Abstract Strain-rate effects can distort model testing with geometrically-similar models. In impact modelling this problem is usually addressed by revising the impact conditions, but such kind of method is inadequate for modelling impact on a reticulated dome. A new technique was proposed and tested. Apart from adjusting the impact conditions, the technique
