Self Friability of Falling Objects

open access: yesBulletin of JSME, 1980
When a brittle body falls under its own weight and strikes a rigid surface, tensile stresses are set up that cause fracture. This is called self friability. A recent paper (1) has experimentally investigated the self friability of disc shaped bodies with central hole.

Drivers of Mouse Plagues: Exceptional Rainfall Following Prolonged Drought Triggers Mouse Plagues in Southeastern Australia

open access: yesIntegrative Zoology, EarlyView.
This study identified a specific sequence of an extended drought followed by exceptional rainfall as a necessary precursor for mouse plagues in southeastern Australia. Long‐term rainfall anomalies interact with ecological processes to reset population dynamics, creating conditions that support rapid mouse population growth following periods of ...

Effect of microstructure on friability in the system Al2O3-ZrO2

open access: yesWear, 1978
Abstract This paper summarizes results on the use of quantitative microscopy in relating microstructural features to the friability of a model abrasive material, Al2O3-ZrO2. Quantitative stereology was used to characterize the geometric aspects of the microstructure of fused Al2O3-ZrO2 abrasives and to relate these to friability.

Edge Sharpness Does Not Vary Between Palaeolithic Flake Technologies, With the Possible Exception of Levallois Débitage

open access: yesArchaeometry, EarlyView.
ABSTRACT Investigating why hominins adopted particular flake technologies during the Mid‐to‐Late Pleistocene is essential to understanding patterns of lithic innovation. This period witnessed the emergence of Levallois technologies (~350–250 ka) and later blades, each “replacing” earlier forms.

Tracing Identity in a Fragmented Past: Multi‐Proxy Analysis of Human Skeletal Remains From Dungowan Creek, New South Wales, Australia

open access: yesArchaeometry, EarlyView.
ABSTRACT Human skeletal remains constitute critical archaeological evidence for reconstructing past societies, yet their investigation requires careful ethical, cultural, and legislative consideration. This paper reports on the discovery, recovery and analysis of a set of skeletal remains encountered during a cultural heritage management (CHM ...

Thorncliffe Formation: A proglacial to subglacial lacustrine basin sequence, Greater Toronto Region, Canada

open access: yesBoreas, EarlyView.
Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.

Requalification of Friability Testing Apparatus

open access: yes
Re-qualification as a part of validation is the task performed to identify or check that utilities, equipment and ancillary systems can operate within limits for their intended use. Equipment qualification is a key element in the pharmaceutical quality system. In recent times regulatory agencies are more focusing on qualification of equipment.

Conservation implications of low contemporary connectivity along the Mid‐Atlantic Ridge in hydrothermal vent gastropods

open access: yesConservation Biology, EarlyView.
Abstract Polymetallic sulfide deposits produced at hydrothermal vent fields are targets for mining exploitation along the Mid‐Atlantic Ridge, threatening the functioning and resilience of vent ecosystems that provide multiple ecosystem services. Knowledge about connectivity between vents will inform conservation practices.
