Heat waves result in significant excess mortality, particularly amongst elderly people. This article examines selected heat wave response plans at national, state/provincial, and municipal levels, with a particular focus on specific responses aimed at residents of aged care facilities. We sourced heat wave response plans from several countries that are experiencing a demographic transition that features a growing aging population. We collected a total of 23 heat wave response plans; most of those plans were from Australia, with only three plans each available from Canada and the UK, and only two available from the U...

Repeated warnings by the scientific community on the dire consequences of climate change through global warming to the ecology and sustenance of our planet have not been give appropriate attention by the U.S. public. Research has shown that climate change is responsible for catastrophic weather occurrences--such as floods, tornadoes, hurricanes, and heat waves--resulting in environmental and public health issues. The purpose of this report is to examine factors influencing public views on climate change. Theoretical and political perspectives are examined to unpack opinions held by the public in the U...

The aims of this study are to explore the "offensive" summer weather types classified under the spatial synoptic classification (SSC) system and to evaluate their impacts on excess mortality in 14 Korean cities. All-cause deaths per day for the entire population were examined over the summer months (May-September) of 1991-2010. Daily deaths were standardized to account for long-term trends of subcycles (annual, seasonal, and weekly) at the mid-latitudes. In addition, a mortality prediction model was constructed through multiple stepwise regression to develop a heat-health warning system based on synoptic climatology...

Kaouther Kerboua, Oualid Hamdaoui
The scientific interest toward the study of acoustic bubble is mainly explained by its practical benefit in providing a reactional media favorable to the rapid evolution of chemical mechanism. The evolution of this mechanism is related to the simultaneous and dependent variation of the volume, temperature and pressure within the bubble, retrieved by the resolution of a differential equations system, including among others the thermal balance. This last one is subject to different assumptions, some authors deem simply that the temperature varies adiabatically during the collapsing phase, without considering the reactions heat of the studied mechanism...

Global climate change is often expected to disrupt biological control. Predicting the effects of climate change on biological control, and identifying natural enemies that will thrive in future climate scenarios, is thus essential to ensure agricultural sustainability. To promote biological control under climate change, land managers should prioritise the conservation of natural enemy diversity to ensure some effective natural enemies are always present despite often-unpredictable climate scenarios. In addition, ecophysiological and habitat domain models should be combined to predict climate change-induced shifts in predation by diverse predator communities...

Seawater warming associated to the ongoing climate change threatens functioning and survival of keystone coastal benthic species such as seagrasses. Under elevated temperatures, the production of reactive oxygen species (ROS) is increased and plants must activate their antioxidant defense mechanisms to protect themselves from oxidative damage. Here we explore from a molecular perspective the ability of Mediterranean seagrasses to activate heat stress response mechanisms, with particular focus on antioxidants...

This study aimed to investigate the effects of repeated extracorporeal shock wave lithotripsy (ESWL) on the kidneys of prepubertal and adult rats. Thirty rats were used: 15 were prepubertal (3 weeks of age) with an average body weight of 72.3 ± 3.3 g, and 15 were adults with of 265 ± 11.3 g. The prepubertal and adult rats were separately and randomly allocated to three groups, each consisting of five rats. Following anesthetization, the left kidney of each rat in each group received shock waves in one, two, or three sessions separated by 72 h...

Widespread agricultural losses attributed to drought, often combined with high temperatures, frequently occur in the field, namely in Mediterranean climate areas, where the existing scenarios for climate change indicate an increase in the frequency of heat waves and severe drought events in summer. Grapevine (Vitis vinifera L.) is the most cultivated fruit species in the world and the most valuable one and is a traditional Mediterranean species. Currently, viticulture must adjust to impending climate changes that are already pushing vine-growers toward the use of ancient and resilient varieties...

INTRODUCTION: We investigated whether the concomitant use of diuretics, non-steroidal anti-inflammatory drugs, and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (triple whammy, TW) predicts in-hospital acute kidney injury (AKI) and whether admission during recorded periods of extreme heat influences this association. METHODS: We retrospectively collected data on patient characteristics and use of TW/non-TW drugs on admission, AKI (increase in serum creatinine ≥ 27 µmol/l either within the first 48 h of admission or throughout hospitalization, primary outcome), length of stay (LOS), and mortality (secondary outcomes) in medical patients ≥65 years admitted (1) during five consecutive heat waves (HWs) between 2007 and 2009 (n = 382) or (2) either before or after each HW, matched for HW period, age, and admission day of the week (non-HW, controls, n = 1339)...

An approach for analytical description of thermal processes in harmonic lattices is presented. We cover longitudinal and transverse vibrations of chains and out-of-plane vibrations of two-dimensional lattices with interactions of an arbitrary number of neighbors. Motion of each particle is governed by a single scalar equation and therefore the notion ``scalar lattice'' is used. Evolution of initial temperature field in an infinite lattice is investigated. An exact equation describing the evolution is derived...

The synthesis of durable and low-cost electrocatalyst is crucial but challenging. Here, we developed a one-pot pyrolysis approach toward the preparation of heteroatom-doped hierarchical porous three-dimensional (3D) graphene frameworks decorated with multilayer graphene shell-coated cobalt oxide nanocrystal. Large literal sheet size of graphene nanomeshes may stimulate rapid thermolysis with cobalt-oleate complex to form Co3O4 nanocrystals and in situ growth of multilayer graphene coating co-doped by boron and nitrogen with controlling heating rate up to 600 °C...

BACKGROUND: High indoor temperatures require behavioral adaptation, especially among vulnerable older adults. There are uncertainties as to the degree to which people adapt to these challenging conditions. OBJECTIVE: The aim of this study was to describe the degree of adaptation of social participation and other heat-related behavior with respect to higher indoor temperatures. METHODS: In this study 81 residents from 10 sheltered living facilities (84% women, mean age 80...

Ocean warming is known to alter the performance and fitness of marine organisms albeit the proteome underpinnings of species thermal tolerance are still largely unknown. In this 1-month experiment we assessed the vulnerability of the gilt-head sea bream Sparus aurata, taken here as a biological model for some key fisheries species, to ocean warming (control 18°C, nursery ground temperature 24°C and heat wave 30°C). Survival was impaired after 28 days, mainly at 30°C although fishes' condition was unaltered...

Exploiting supercritical geothermal resources represents a frontier for the next generation of geothermal electrical power plant, as the heat capacity of supercritical fluids (SCF),which directly impacts on energy production, is much higher than that of fluids at subcritical conditions. Reconnaissance and location of intensively permeable and productive horizons at depth is the present limit for the development of SCF geothermal plants. We use, for the first time, teleseismic converted waves (i.e. receiver function) for discovering those horizons in the crust...

Remotely controlled, localized drug delivery is highly desirable for potentially minimizing the systemic toxicity induced by the administration of typically hydrophobic chemotherapy drugs by conventional means. Nanoparticle-based drug delivery systems provide a highly promising approach for localized drug delivery, and are an emerging field of interest in cancer treatment. Here, we demonstrate near-IR light-triggered release of two drug molecules from both DNA-based and protein-based hosts that have been conjugated to near-infrared-absorbing Au nanoshells (SiO2 core, Au shell), each forming a light-responsive drug delivery complex...

Warmer and drier climatic conditions are projected for the 21st century; however, the role played by extreme climatic events on forest vulnerability is still little understood. For example, more severe droughts and heat waves could threaten quaternary relict tree refugia such as Circum-Mediterranean fir forests (CMFF). Using tree-ring data and a process-based model, we characterized the major climate constraints of recent (1950-2010) CMFF growth to project their vulnerability to 21st-century climate. Simulations predict a 30% growth reduction in some fir species with the 2050s business-as-usual emission scenario, whereas growth would increase in moist refugia due to a longer and warmer growing season...

Sexual reproduction in predominantly clonal marine plants increases recombination favoring adaptation and enhancing species resilience to environmental change. Recent studies of the seagrass Posidonia oceanica suggest that flowering intensity and frequency are correlated with warming events associated with global climate change, but these studies have been observational without direct experimental support. We used controlled experiments to test if warming can effectively trigger flowering in P. oceanica. A six-week heat wave was simulated under laboratory mesocosm conditions...

The role of the p38 MAPK signaling cascade was studied in stress response of RAW 264.7 macrophages to extremely low-intensity centimeter microwaves. Irradiation stimulated production of a number of cytokines (IL-1, IL-6, TNF-α, INF-γ and IL-10), as well as induced activation of the signaling cascades NF- κB and p38 MAPK, and enhanced expression of Hsp72 heat shock protein. In the presence of the cascade p38 MAPK inhibitor (p38 MAP kinase inhibitor XI), the stimulating effects of electromagnetic waves were abrogated either completely (for NF-κB and Hsp72) or partially (for p38 MAPK and cytokines)...

High intensity focused ultrasound (HIFU) or focused ultrasound surgery (FUS) is a non-invasive technique for the treatment of cancerous tissue, which is limited by difficulties in getting real-time feedback on treatment progress and long treatment durations. The formation and activity of acoustic cavitation, specifically inertial cavitation, during HIFU exposures has been demonstrated to enhance heating rates. However, without the introduction of external nuclei its formation an activity can be unpredictable, and potentially counterproductive...
