1. Mortality risk during heat waves in the summer 2013-2014 in 18 provinces of Argentina: Ecological study
Resumo O aumento da frequência das ondas de calor (OsC) é uma das consequências proeminentes das alterações climáticas. O seu impacto na saúde humana tem sido relatado principalmente no hemisfério norte, mas tem sido mal estudado no hemisfério sul. O objetivo deste estudo foi analisar os efeitos das OsC ocorridas no verão de 2013-14 sobre a mortali

3. Mortalidad por olas de calor en la ciudad de Buenos Aires, Argentina (2005-2015)
Resumo: O objetivo deste trabalho é analisar a mortalidade durante as ondas de calor na cidade de Buenos Aires, Argentina, no período de 2005-2015. Foi usado um desenho de séries temporais com modelos aditivos generalizados, vinculando a mortalidade com dias de onda de calor em todo o período, e com dias da onda de calor em 2013, a mais prolongada desde

5. Market reaction to bank merger and acquisition events in Brazil: an analysis of the effects of market waves
RESUMO O objetivo deste estudo é investigar a reação do mercado de ações a eventos de fusões e aquisições (F&A) de bancos no Brasil ocorridos em momentos de aquecimento do mercado. Este artigo visa preencher a lacuna de pesquisa sobre F&A bancárias e seus efeitos, em especial aquelas advindas de ondas de F&A. Esse campo se encontra aberto na literat

6. Physiological responses and animal behavior in Bonsmara-Hereford crosses vs. Hereford purebred on environment stress
ABSTRACT: Adaptative traits (rectal temperature-RT, respiratory rate-RR) and grazing behavior (Grazing, Ruminating and Rest time, and Sun or Shade time) of Bonsmara-Hereford crossbred-BH, n = 15, and purebred Hereford-HH, n = 18, yearling heifers, in a grazing system of Uruguay. Environment characterization was made using THIadjusted by radiation and wind sp

7. Monitoring Heat Treatments in Steels by a Non Destructive Ultrasonic Method
In order to determine if heat treatments can be discerned by nondestructive ultrasonic testing, samples of SAE 1045 and SAE 4140 steels were subjected to the classical heat treatments of annealing, normalizing, quenching, and quenching and tempering, and their elastics constants, Young's, shear and Poisson's moduli, were monitored by ultrasound. Results show

8. Acoustic Birefringence and Poisson's Ratio Determined by Ultrasound: Tools to Follow-Up Deformation by Cold Rolling and Recrystallization
Poisson's ratio and birefringence, both measured by ultrasound, are used to follow the evolution of the anisotropy in ASTM A-36 steel plates cold-rolled between 5 and 50% deformation, and then subjected to recrystallization at 900 and 1000 ºC. Times of flight of longitudinal and shear waves along the thickness of the plates were measured. As orthotropy incr

9. Study on Dynamic Compressive Mechanical Properties and Failure Modes of Heat-Treated Granite
Abstract Temperature and external load are two important factors affecting the mechanical properties of rock material. The test on heat- treated granite specimen was carried out by using an improved split Hopkinson pressure bar (SHPB). Based on the test data, the dynamic behavior and failure characteristics of the granite under the coupling action of tempera

10. Dynamic Properties of Coupled Tube-Array Structures with the Axial Loads
Abstract The tube-array structures coupled both with the fluid and the axial load is focused. In a heat exchanger, the tubes are frequently affected by cold and hot fluid shock waves. Thus, tubes are often found to be vibrated and even to be worn out. This vibration may not only alter the performance of the tubes but also introduce the damage in the heat exc

11. Propagation of waves in micropolar generalized thermoelastic materials with two temperatures bordered with layers or half-spaces of inviscid liquid
The aim of the present paper is to study the propagation of Lamb waves in micropolar generalized thermoelastic solids with two temperatures bordered with layers or half-spaces of inviscid liquid subjected to stress-free boundary conditions in the context of Green and Lindsay (G-L) theory. The secular equations for governing the symmetric and skew-symmetric l

12. Thermoelastic slowness surfaces in anisotropic media with thermal relaxation
Analysis for general closed form solution of the thermoelastic waves in anisotropic heat conducting materials is obtained by using the solution technique for the biquadratic equation in the framework of the generalized theory of thermoelasticity. Obtained results are general in nature and can be applied to the materials of higher symmetry classes such as tra
