Lost in aggregation? On the importance of local food price data for food poverty estimates
American Journal of Agricultural Economics, EarlyView.Abstract This paper explores within‐country variations in food price dynamics and food poverty estimates by employing local market price data and national consumer price index (CPI) data. Our results show that national CPI data may be useful for approximating national trends but they fail to detect and identify spatial variations in local trends, which

American Journal of Industrial Medicine, EarlyView.ABSTRACT Introduction Global increases in occupational heat exposure are raising concerns about worker safety and cognitive performance during prolonged and repeated shifts. At present, the cumulative effects of repeated heat exposure on cognitive performance remain unclear.

Thermal Shock Tests and Thermal Shock Parameters for Ceramics
Journal of the Korean Ceramic Society, 2012Thermal shock test methods and thermal shock parameters for ceramics were reviewed from the following viewpoints: (1) The test methods should be based on the precise estimation of both temperature and thermal stress distributions in a specimen taking into account the temperature-dependent thermo-mechanical properties; (2) The thermal shock parameters ...

Physical Review Letters, 2005
The Ludwig-Soret effect or thermal diffusion, which refers to the separation of liquid mixtures in a temperature gradient, is governed by a nonlinear, partial differential equation in space and time. It is shown here that the solution to the nonlinear differential equation for a binary mixture predicts the existence of shock waves completely analogous ...

SIAM Journal on Applied Mathematics, 1985
Ignition of an initially cold combustible gas is studied when chemical reaction is switched on due to the passage of a piston-supported shock of sufficient strength. The time and space history of the shocked gas up to the instant of thermal runaway is described, by using a combination of asymptotic and numerics.

Thermal equilibration in a shock wave
Physical Review Letters, 1992Absolute-intensity measurements of luminous emissions from shocked silicon show significant disagreement with predictions that assume thermal equilibrium between electrons and ions is reached immediately behind the shock front. Taking into account both electron-ion equilibration and electron thermal conduction, we have estimated an electron-ion ...

Thermal shock and dilution shock as the causes of freezing injury
Cryobiology, 1973Abstract We suggest that during slow freezing, cellular membranes are altered by the hypertonic solutions produced. This alteration in itself does not cause membrane leakage of normally impermeant solutes but it renders the cells susceptible to solute leakage on the application of a stress, which is provided during freezing by the reduction in ...

Thermal Shock and Thermal Fatigue Testing
Journal of Testing and Evaluation, 1991Abstract A method is described for rapidly screening candidate materials used in severe thermal shock applications. The method involves electron beam heating the surface of specimens using a thermal flux equal to that experienced during actual service operation. Two methods of electron beam radiation are described.

Thermal Shock Resistance of Skin Tissue
Journal of Medical Systems, 2010Understanding the mechanisms of skin behavior under thermal shock is crucial for medical treatments. However, no reasonable criteria are available for the maximum thermal loadings that skin tissue can survive. To address this, in this paper we analyzed thermal and neural behaviors of skin tissue exposed to thermal loadings by introducing the thermal ...
