21. Thermal effects ( extremely high or low temperature ) can result in necrosis due to the disruption of cells.22. This, low cropping techniques and the thermal effect of the rock produces great intensity for the grapes and subsequent wine. 23. Later experiments show some of these early reports to be artifacts and rate enhancement is strictly due to thermal effects . 24. Joule heating frequency is kept well above 20 kHz to avoid feedback response and to separate topological and thermal effects . 25. Reserahcers at Kemakta Konsult AB ( Sweden ) have done detailed modelling of thermal effects on groundwater flow near boreholes. 26. The best mountings may be in deep boreholes, which avoid thermal effects , ground noise and tilting from weather and tides. 27. As such, there is a sharper distinction, relative to thermal effects , between areas of high lethality and areas with minimal radiation doses. 28. This thermal effect is called " temperature dependency " and prevents these devices from achieving true sunglass darkness in very hot weather. 29. But only one is set to study non-thermal effects _ and this is due to be carried out by de Pomerai's team. 30. Severe local fallout contamination can extend far beyond the blast and thermal effects , particularly in the case of high yield surface detonations.
