Insects at Not So Low Temperature: Climate Change in the Temperate Zone and Its Biotic Consequences

Herein, we consider insects in the temperate zone where, in central and eastern continental land masses, favorable summers are interspersed with inamicable, often lethal, winters. At latitudes higher than 30°, fitness consists of the ability to exploit the warm season through growth, development and reproduction, the ability to avoid or mitigate the effects of winter cold through dormancy or mi...

Green Method for Synthesizing Gallium Nitride Nanostructures at Low Temperature

Gallium nitride (GaN) nanostructures (NS) were synthesized using pulseddirect current plasma enhanced chemical vapor deposition (PDC-PECVD) on quartzsubstrate at low temperature (600°C). Gallium metal (Ga) and nitrogen (N) plasma wereused as precursors. The morphology and structure of the grown GaN NS werecharacterized by field emission scanning electron microscope (FE-SEM), transmissionelectro...

Demagnetization of spin systems at low temperature

We report on analytical and numerical results for the time evolution of a ~lattice! model of ferromagnetic particles after field inversion. Relaxation from the metastable phase occurs by superposition of two independent spin-flip processes: with probability 12p , the flip obeys the Metropolis rule at finite temperature, T , while the flip is performed at random, as for T→` , with probability p ...

Low-temperature olivine rheology at high pressure

San-Carlos olivine rheology was investigated at pressure (P) up to 9 GPa and temperature (T) lower than 890 ◦C. Six powder specimens were cold compressed and sintered into dense and compact materials, then deformed during relaxation experiments carried out at constant pressure and temperature in DIA-type cubic-anvil apparatus. Sample elastic strain was monitored during relaxation by in situ X-r...
