The origin of tubular lava stalactites and other related forms [PDF]
International Journal of Speleology, 1998 Tubular lava stalactites are often found in lava tubes. Field observations, sample analysis, and comparative studies indicate that these are segregations extruded during cooling from partially crystallized lava al about 1,070 - 1,000 °C.

Wildlife Biology, EarlyView.We compared population trends for rock ptarmigan Lagopus muta densities (2003‒2019) derived from walked transects and driven road transects in Mosfellsheiði and Slétta in southwest and northeast Iceland, respectively. The walked transects were laid out according to a random rule.

The Syntactic Status of Subject Clitics: A Problem from Venetan SE‐Constructions
Transactions of the Philological Society, EarlyView.Abstract This article reopens the discussion on the syntax of subject clitics (SCLs) in Venetan dialects by providing a problematic piece of data and outlining its theoretical consequences. New evidence from se‐constructions in Alto Polesine Venetan (APV) shows that SCLs resist a unitary categorisation even within the same dialect group: in varieties ...

Archaeometry, EarlyView.Abstract The use of stone hammers to produce sharp stone flakes—knapping—is thought to represent a significant stage in hominin technological evolution because it facilitated the exploitation of novel resources, including meat obtained from medium‐to‐large‐sized vertebrates. The invention of knapping may have occurred via an additive (i.e., cumulative)
