BACKGROUND The health impacts of heat waves are serious and have prompted the development of heat wave response plans. Even when they are efficient, these plans are developed to limit the health effects of heat waves. This study was designed to determine relevant indicators related to health effects of heat waves and to evaluate the ability of a syndromic surveillance system to monitor variatio...

Shock waves are defined as types of acoustic pressure waves that develop during sudden releases of energy. The best-known natural phenomenon is thunder following lightning. Another example is the “bang” an aircraft produces when it breaks the sound barrier. Both focused shock waves and unfocused sound waves are produced in these examples. Additionally, almost all other forms of energy are relea...

In this chapter, we study the solutions, both analytical and numerical, to the two most important equations of one-dimensional continuum dynamics. The heat equation models the diffusion of thermal energy in a body; here, we analyze the case of a one-dimensional bar. The wave equation describes vibrations and waves in continuous media, including sound waves, water waves, elastic waves, electroma...

In the Mediterranean basin, the globally increasing temperatures are expected to be accompanied by longer heat waves. Commonly assumed to benefit cold-limited invasive alien species, these climatic changes may also change their feeding preferences, especially in the case of omnivorous ectotherms. We investigated heat wave effects on diet choice, growth and energy reserves in the invasive red sw...

Background There was no consistent definition for heat wave worldwide, while a limited number of studies have compared the mortality effect of heat wave as defined differently. This paper aimed to provide epidemiological evidence for policy makers to determine the most appropriate definition for local heat wave warning systems. Methods We developed 45 heat wave definitions (HWs) combining tem...

BACKGROUND Heat-wave frequency, intensity, and duration are increasing with global climate change. The association between heat and mortality in the elderly is well documented, but less is known regarding associations with hospital admissions. OBJECTIVES Our goal was to determine associations between moderate and extreme heat, heat waves, and hospital admissions for nonaccidental causes among...

Heat waves take a major toll on human populations, with negative impacts on the economy, agriculture, and human health. As a result, there is great interest in studying the changes over time in the probability and magnitude of heat waves. In this paper we propose a hierarchical Bayesian model for serially-dependent extreme temperatures. We assume the marginal temperature distribution follows th...

Data from heat flow and gramivetric tides are at our disposal in the island of Lanzarote (Canary Islands); its formation is known and, in addition to it, a model of its. crust which provides us with its thicknes is at our disposal. When studying the relationship among these parameters, a disagreement with the results obtained from previous studies is observed; those studies show a clear relatio...
