ABSTRACT Preserved allocyclic signatures in the rock record often reflect basin‐scale climatic variability and serve as key proxies for correlating ancient dryland successions. The notion of climate cyclicity, however, remains largely untested on regionally constrained, outcrop‐calibrated studies.

Studying Elastic Deformation Behaviour of Cast Irons by Acoustic Emission
The deformation of metallic materials includes both an elastic and a plastic deformation. In the case of cast irons, the elastic region becomes less pronounced as the graphite changes from spheroidal to flake shaped, as observed in nodular and grey cast ...

Microstructure investigation of cast irons with nodular and flake graphite via nanoindentation
The paper investigates and compares the local mechanical properties of microstructure components in grey iron EN GJL -300 and ductile iron EN GJS -500-7. The microstructure of both cast irons is analysed by LOM, and then certain microstructure components

ABSTRACT Numerous buildings, monuments, and infrastructural works in Verona were constructed during the Roman period using stone, a material abundantly available from quarrying areas located relatively close to the city. Petrographic investigations conducted by Transmitted Polarized Light Optical Microscopy (TPL‐OM) and complemented by colorimetric ...

This study of recent exploration drillcore reveals two sequences separated by a disconformity. Basal alluvial fan to shallow marine lithofacies suggest reactivation of basement faults, and a distinct upwelling signature points to a flooded margin, controlled by differential subsidence of diverse Proterozoic lithosphere.

Description and modeling of the Jiddat al Harasis 091 L5 strewn field
Abstract With a size of 51.2 × 7.2 km, the 10.9 ± 1.7 ka old Jiddat al Harasis 091 L5 chondrite strewn field is the largest known in Oman. It consists of more than 700 meteorites with a total mass of >4.5 tons from which the largest six stones of >100 kg to 1.5 tons make up two thirds of the total mass.

Abstract Coralline algae are key benthic components of shallow‐marine ecosystems globally and as habitat‐formers they support high biodiversity levels. Experiments on living coralline algae show internal growth changes in response to warming and higher CO2.

The Relation between Porosity and Solidification Mechanism in Grey Cast Iron
The factors resulting in porosity in various types of cast iron were fairly well understood by 1960. These factors are now reviewed. The importance of the details of the solidification sequence is stressed and the special features of the eutectic ...

Global Warming Affects the Pathogenesis of Important Fish Diseases in European Aquaculture
The effect of global warming on pathogens and their fish hosts that could exacerbate the negative outcomes for aquaculture. Changes in farming practices and the development of innovative mitigation tools may prove essential to cope with the effects and impacts of rising water temperatures on fish diseases in Europe.

ABSTRACT Mongolia's Eastern and Western Gobi Basins preserve a globally significant record of Cretaceous terrestrial vertebrates, yet their biostratigraphic correlations are complicated by a complex geological history. The Eastern Gobi Basin, a northeast‐southwest trending fault‐bounded rift system, includes several minor sub‐basins with distinct ...
