IMPROVEMENT OF Chrysanthemum × grandiflorum (Ramat.) Kitam. ENCAPSULATION-DEHYDRATION CRYOPRESERVATION PROTOCOL

open access: yesActa Scientiarum Polonorum: Hortorum Cultus, 2014
To optimize the protocol, the shoot tips of Chrysanthemum × grandiflorum (Ramat.) Kitam. radiomutants have been cryopreserved using the encapsulationdehydration technique, following different approaches. In the experiment the influence of abscisic acid –

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy

open access: yesAdvanced Engineering Materials, EarlyView.
This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Potential desiccation cracks on Mars: A synthesis from modeling, analogue-field studies, and global observations

open access: yes, 2014
Potential desiccation polygons (PDPs) are polygonal surface patterns that are a common feature in Noachian-to-Hesperian-aged phyllosilicate- and chloride-bearing terrains and have been observed with size scales that range from cm-wide (by current rovers)

Effects of recurrent disturbances on the periphyton community downstream of a dammed watercourse

open access: yesBrazilian Journal of Biology
We evaluate experimentally the effect of a sequential disturbance—desiccation—on the structure and dynamics of a periphytic algal community in a semilotic environment of the Upper Paraná River floodplain.

Microstructure Evolution of a VMnFeCoNi High‐Entropy Alloy After Synthesis, Swaging, and Annealing

open access: yesAdvanced Engineering Materials, EarlyView.
The synthesis and processing (rotary swaging and annealing) of the novel VMnFeCoNi alloy is investigated, alongside the estimation of the grain size effect on hardness. Analysis of a wide grain size range of recrystallized microstructures (12–210 µm) reveals a low annealing twin density.

Desiccation Tolerance in Listeria monocytogenes: Mechanisms and Importance for Food Safety

open access: yes, 2013
This study examined some of the environmental, physiological, and genetic factors or mechanisms which contribute to L. monocytogenes’ desiccation survival under food processing conditions.

Isolation of radiation-resistant bacteria from Mars analog antarctic dry valleys by preselection, and the correlation between radiation and desiccation resistance

open access: yes, 2015
Extreme radiation–resistant microorganisms can survive doses of ionizing radiation far greater than are present in the natural environment. Radiation resistance is believed to be an incidental adaptation to desiccation resistance, as both hazards cause ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

open access: yesAdvanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

Cross-tolerance in larvae of the goldenrod gall fly, Eurosta solidaginis: rapid desiccation increases organismal and cellular freeze-tolerance

open access: yes, 2012
A number of similarities exist that support the idea of cross-tolerance between low temperature and desiccation stress responses. Freeze-tolerant larvae of the goldenrod gall fly, Eurosta solidaginis, are exposed to extremely dry and cold conditions when
