Fact Sheet: Extreme Heat, 2009

Doing too much on a hot day, spending too much time in the sun or staying too long in an overheated place can cause heat-related illnesses. Know the symptoms of heat disorders and overexposure to the sun, and be ready to give first aid treatment.

Heat perception and signalling in plants: a tortuous path to thermotolerance.

An accurate assessment of the rising ambient temperature by plant cells is crucial for the timely activation of various molecular defences before the appearance of heat damage. Recent findings have allowed a better understanding of the early cellular events that take place at the beginning of mild temperature rise, to timely express heat-shock proteins (HSPs), which will, in turn, confer thermotolerance to the plant. Here, we discuss the key components of the heat signalling pathway and suggest a model in which a primary sensory role is carried out by the plasma membrane and various secondary messengers, such as Ca(2+) ions, nitric oxide (NO) and hydrogen peroxide (H(2) O(2) ). We also describe the role of downstream components, such as calmodulins, mitogen-activated protein kinases and Hsp90, in the activation of heat-shock transcription factors (HSFs). The data gathered for land plants suggest that, following temperature elevation, the heat signal is probably transduced by several pathways that will, however, coalesce into the final activation of HSFs, the expression of HSPs and the onset of cellular thermotolerance.

Design and construction of precision heat fluxmeters

InAlAs/InGaAs/InP based high electron mobility transistor devices have been structurally and electrically characterized, using transmission electron microscopy and Raman spectroscopy and measuring Hall mobilities. The InGaAs lattice matched channels, with an In molar fraction of 53%, grown at temperatures lower than 530¿°C exhibit alloy decomposition driving an anisotropic InGaAs surface roughness oriented along [1math0]. Conversely, lattice mismatched channels with an In molar fraction of 75% do not present this lateral decomposition but a strain induced roughness, with higher strength as the channel growth temperature increases beyond 490¿°C. In both cases the presence of the roughness implies low and anisotropic Hall mobilities of the two dimensional electron gas.

Pentateuque, Hexateuque et historiographie deutéronomiste. Le problème du début et de la fin du livre de Josué

The book of Joshua is in the very center of the recent discussion about the existence of a coherent deuteronomistic redaction in Deut to 2 Kings during the exilic period. This article analyses the beginning (Josh 1.1-9) and the end (Josh 23 and 24) of Josh. Josh 1.1-2,5-7 and chapter 23 belong to the dtr edition. Josh 23 was followed by Judg 2.6ff. During the Persian period, Deuteronomists and priests intended to publish one Law for the whole community. There was probably a discussion whether the Torah should be a Penta- or a Hexateuch. This discussion may explain such a text as Josh 24 which clearly tries to construct an Hexateuch (cf. also Gen. 50.25: Exod 13.19; Josh 24.32). But since the Torah is about foundations, the main theological trends agreed to have its end with the death of Moses.
