Figure 2 in High-temperature stress induces bacteria-specific adverse and reversible effects on Ulva (Chlorophyta) growth and its chemosphere in a reductionist model system
Figure 2: Bioassay for morphogenetic activity performed at 18 °C. Using a tripartite community with Ulva mutabilis, the morphogenetic activity of the thallusin-releasing bacteria Maribacter sp. was complemented by one out of the four strains isolated from the surface of Ulva ohnoi. Under standard conditions, axenic gametes (A) were cultivated in the tissue culture flask with the tested bacteria alone (B–E), in the presence of Roseovarius sp. (G–J) or with Maribacter sp. MS6 (L–O) in comparison to the controls (F and K). Arrows with closed heads indicate protrusion formation due to the lack of thallusin released by Maribacter sp. Arrows with open heads indicate rhizoid formation in the presence of Maribacter sp. Magnification bar = 100 µm.
Figure 1 in High-temperature stress induces bacteria-specific adverse and reversible effects on Ulva (Chlorophyta) growth and its chemosphere in a reductionist model system
Figure 1: Workflow. Selected bacteria IH2, IH18, IH25, and G8 were collected from the surface of Ulva ohnoi, phenocopying the activity of Roseovarius sp. MS2 and forming a tripartite community with Maribacter sp. MS6 and the gametophyte of Ulva mutabilis (morphotype "slender"; strain FSU-UM5-1). Ulva mutabilis (25 mg dry weight) was cultivated with the two bacterial strains (OD620 = 0.001) under standard conditions (Wichard and Oertel 2010). Propagules of equal length were stressed by a temperature shift from 18 °C to 30 °C using continuous light (80 µmol photon m−2 s−1) to avoid chronobiological effects. Axenic cultures and tripartite communities were prepared according to Spoerner et al. (2012). exo-Metabolomics and multivariate analysis of the metabolite profiling of the supernatant (150 mL) of four tripartite communities were performed according to Alsufyani et al. (2017) and Ghaderiardakani et al. (2022). Drawings of Ulva were taken from Wichard (2023) under the terms of CC BY 4.0. Created with BioRender.com.

High Temperature Compression Studies of a Zr-2.5Nb Alloy using Deformation Dilatometer
<p>Data recorded in uniaxial compression for a Zr-2.5Nb alloy deformed at temperatures of 650C, 675C, 700C, 725C, 750C, 775C, 800C, 825C and 850C, at strain rates of 10-2.5, 10-2, 10-1.5, 10-1, 10-0.5 and 1 s-1, to 50% height reduction, using TA Instruments DIL 805 A/D/T Quenching and Deformation Dilatometer. The cylindrical samples measured 5 mm diameter and 10 mm height. The Zr-2.5Nb specimens were machined from the centre of an as-received forged plate manufactured at Wah Chang, with a beta-transformed starting microstructure. Si3N43 platens were used for all tests, with graphite lubricant applied at the ends of the sample to minimise friction. Tests were conducted in an inert He gas atmosphere. Temperature was controlled using an S-Type thermocouple spot-welded to the centre of the samples.</p> <p>Data recorded at high acquisition frequency during deformation is stored in the 'deformation_files' folder and saved with the format: ' test number (001 to 191)_temperature_log(strain rate)_repeat number (01 or 02)'. Data in the 'basic_files' folder is recorded at a lower acquisition frequency, but includes recording of the entire themomechanical cycle, including both heating and cooling stages, as well as deformation. The 'software_files' folder includes metadata stored in the form of a parameter file (.par and .pad), along with a Windows data file (.D5D) that can be loaded and analysed within the dilatometer user interface.</p> <p>An <a href="https://doi.org/10.5281/zenodo.3673105">accompanying python script</a> will allow the user to plot the stress-strain data using the Jupyter Notebook application, along with generating 'processing maps' of the material. A critical assessment of the application of 'processing maps' is included in the accompanying paper;</p> <p>C. S. Daniel, P. Jedrasiak, C. J. Peyton, J. Quinta da Fonseca, H. R. Shercliff, L.

Figure 1. Mean values (± S.E.) for mass (A), body length (B), and pea aphid (Acyrthosiphon pisum) consumption rate (C) of Episyrphus balteatus larvae per day of experiment depending on rearing temperature. Dot shapes correspond to temperature treatments: circle to 20 °C (red), triangle to 23 °C (green), and square to 26 °C (blue). After post-hoc tests with Bonferroni correction, the character '*' corresponds to one significant pairwise comparison, '**' corresponds to two significant pairwise comparisons among the temperature treatments. Details of the mean values and statistical test outcomes per day of the experiment are given in Table 1.
MSCA SHINE_Project: Numerical results of the soldification-melting of a Si-based alloy (Ultra-high temperature storage)
<p>Project 101145914 — SHINE has received funding withing the MSCA framework. The purpose of this project is to construct a generic model describing the solidification-melting process of ultra-high temperature latent heat thermal energy storage systems based on data-driven analysis and rigorous CFD models. Within the initial steps of the project a preliminary database is being created based on available results from previous UPM’s projects (Thermobat Project) as well as preliminary simulations by using a 2D CFD model. The present dataset contains information of FeSiB alloy solidification-melting close to 1250 oC inside a cylindrical container, under various heating conditions. Analysis of the present data can be also found in the manuscript entitled as ¨Numerical analysis on the state of charge of an ultra-high temperature latent heat energy storage system, SoraPaces, Rome, 2024¨</p>
Highly consistent brightness temperature fundamental climate data record from SSM/I and SSMIS
<p>The highly consistent brightness temperature (TB) fundamental climate data record (FCDR) comprises intercalibrated TBs from SSM/I on F11 and F13, and SSMIS on board F17. It covers the time period from December 1991 to December 2021. It provides homogenized and intercalibrated TBs in a user-friendly data format (HDF5). SSM/I and SSMIS data are used for various applications, such as analyses of the hydrological cycle. The improved homogenization and inter-calibration procedure ensure the long-term stability of the FCDR for climate related applications. <br> This data files contain daily TBs data on 1°×1° grid-level of satellite F11, F13 and F17 (Level 2A).<br> It is worth noting that the original sensor TB data are provided by Level-1C dataset. The Level-1C data record is complemented with scan status, quality flags, sun glint angles, and earth incidence angles.</p>
Data for: Tolerance of high temperature and associated effects on reproduction in euedaphic Collembola
<p>Tropical and mid-latitude terrestrial ectotherms are more vulnerable to global warming than species from high latitudes. However, thermal tolerance studies from these regions still lack soil invertebrates. We chose six euedaphic species of Collembola (of the genera <em>Onychiurus</em> and <em>Protaphorura</em>) sampled across latitudes ranging from 31°N to 64°N and first determined their upper thermal limit (UTL) by static assays. Based on their upper thermal limit, we exposed them to temperatures 32 ℃ to 36 ℃ depending on the species for 1-2 hours, which was expected to result in heat-induced injuries equivalent to 5% to 30% mortality within each species. Survivors from this series of increasing heat injuries were used to determine the time to first oviposition, and the number of eggs produced following heat exposure.</p> <p class="content">We found the upper thermal limit positively correlates to the soil temperature of the sampling site. Species have different UTL<sub>60</sub> indicating they have different tolerance to high temperatures. The species order from most heat tolerance to least was <em>O. yodai</em> > <em>P. fimata</em> > <em>P. armata</em> ≈ <em>P. tricampata</em> > <em>P. macfadyeni </em>> <em>P. pseudovanderdrifti</em>. Heat stress inflicted on survivors can prolong the time to regain reproduction in all species, and two species showed reduced egg production. The most heat-tolerant species did not have advantages over the least heat-tolerant species under a sublethal heat exposure scheme (where predicted survival was less than 30%) in terms of their recovery of reproduction. We provided evidence for a potential long-term effect of high temperature on euedaphic species of Collembola and highlighted the need for further studies on the effects of global warming on soil living organisms.</p>
