AI Article Synopsis

  • Piloderma sp. is an ectomycorrhizal fungus that was studied in a symbiotic relationship with Norway spruce using granules of hardened wood ash.
  • The research involved sampling the mycelium near the wood ash granules over 11 weeks, analyzing its elemental content, particularly focusing on calcium (Ca), phosphorus (P), and potassium (K).
  • Results indicated that while P and K levels were similar to control samples, the Ca content significantly increased in both mycelium close to wood ash and in other parts of the mycelium, suggesting Piloderma sp. may primarily aid in short-term Ca storage rather than in P storage.

Article Abstract

Piloderma sp., a wood ash-colonizing ectomycorrhizal (EM) fungus, was grown symbiotically with Norway spruce in microcosms which contained granules of hardened wood ash. Mycelium close to the granules was sampled 3 times over a period of 11 weeks and the elemental content was investigated with particle induced X-ray emission. Mycelium from microcosms without wood ash was used as controls. The contents of P and K were similar in mycelium growing close to wood ash granules to those in control mycelium, while the Ca content increased from 23+/-21 mg g(-1) in controls to 63+/-8 mg g(-1) in mycelium growing close to wood ash granules. The Ca content was also increased in other parts of the mycelium more distant from the wood ash. Piloderma sp. may have a role in the short-term storage of Ca released from wood ash, rather than in releasing and storing P.

Construction materials are significantly exposed to ecological hazards due to the presence of hazardous chemical constituents found in industrial and agricultural solid wastes. This study aims to investigate the use of sawdust particles (SDPs) and sawdust wastewater (SDW) in alkali-activated composites (AACs) made from a mixture of different silicon-aluminum-based solid wastes (slag powder-SP, red mud-RM, fly ash-FA, and carbide slag-CS). The study examines the impact of SDP content, treated duration of SDPs, and SDW content on both fresh and hardened properties of the AACs, including electrical conductivity, fluidity, density, flexural and compressive strengths, and drying shrinkage.

Linking sap flow and tree water deficit in an unmanaged, mixed beech forest during the summer drought 2022.

Temperate mixed forests are currently experiencing severe drought conditions and face increased risk of degradation. However, it remains unclear how critical tree physiological functions such as sap flow density (SFD) and tree water deficit (TWD, defined as reversible stem shrinkage when water is depleted), respond to extreme environmental conditions and how they interact under dry conditions. We monitored SFD and TWD of three co-occurring European tree species (Fagus sylvatica, Fraxinus excelsior and Acer pseudoplatanus) in dry conditions, using high temporal resolution sap flow, dendrometer, and environmental measurements.

Biomass is a key element in biofuels which can be defined as a fuel produced through contemporary biological processes, and its increased use can support the EU's aims of reducing greenhouse gas emissions. Information on the nature and the quality of the biomass or biofuel is important in order to support the optimization of their combustion with respect to realizing higher efficiencies and lower emissions during energy production. Three reference materials were produced by a collaborative approach among national metrology institutes and designated institutes within the scope of the EMPIR project: BIOFMET.

Fetoscopic endoluminal tracheal occlusion (FETO) induces lung growth and may improve survival in congenital diaphragmatic hernia (CDH) but the effect on post-natal right (RV) and left (LV) ventricular size and cardiac function is unknown. Quantitative measures of heart size and function including tricuspid annular plane systolic excursion Z-score (TAPSEZ), RV fractional area change (RVFAC), RV global longitudinal and free wall strain (RVGLS, RVFWS), RV/LV ratio, LV eccentricity index (LVEI), and LV M-mode diastolic and systolic Z-scores (LVIDDZ, LVIDSZ) were compared between FETO and control patients on first post-natal echocardiogram, prior to and post CDH repair, and on last available echocardiogram using non-parametric Wilcoxon rank-sum test in a single-center, retrospective cohort study. Linear regression models evaluated change over time, adjusting for clustering and interaction of echocardiogram parameters with time.

Article Synopsis
  • Identifying Paleolithic communal rituals helps understand group identity and cohesion.
  • Evidence shows that collective rituals took place in Manot Cave during the Early Upper Paleolithic, centered around an engraved boulder resembling a tortoise.
  • Analyses of artifacts and cave acoustics indicate fire was used for illumination, and the site was ideal for gatherings, stressing its role in social networking among EUP communities.
