Archaeometry, Volume 68, Issue S3, Page S8-S30, June 2026.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)

Journal of Applied Entomology, Volume 150, Issue 6, Page 780-790, July 2026.ABSTRACT Norway spruce will likely remain an important tree species in Europe over the next few decades despite efforts to transform forests and reduce its distribution range more to its natural range. Consequently, Ips typographus will remain one of the most relevant forest pests the management of which will become increasingly challenging due to ...

Experimental Study on the distance of rock falls under different influencing factors
工程科学与技术, 2016 :Through the shaking table test, studied the distance of different shape and size rock falls under different peak acceleration seismic, sine wave frequency and slope shape, and cleared the influence of rock falls on the buildings at the slope foot.The ...

A nonlinear model coupling rockfall and rainfall intensity based ewline on a four year measurement in a high Alpine rock wall (Reintal, German Alps) [PDF]
Natural Hazards and Earth System Sciences, 2009 A total of more than 140 000 kg of small-magnitude rockfall deposits was measured in eight rockfall collectors of altogether 940 m<sup>2</sup> in size between 1999–2003 below a 400–600 m high rock face in the Reintal, German Alps ...

Sedimentology, EarlyView.ABSTRACT Tsunami deposits serve as geological records of past events and are essential for understanding the occurrence and dynamics of tsunamis. However, conventional research has largely focused on sandy and boulder deposits, leaving gravel‐dominated tsunami deposits comparatively underexplored; furthermore, their characteristics and formation ...

Semi-Automatic Determination of Rockfall Trajectories
Sensors, 2014 In determining rockfall trajectories in the field, it is essential to calibrate and validate rockfall simulation software. This contribution presents an in situ device and a complementary Local Positioning System (LPS) that allow the determination of ...

Nanoseismic monitoring for detection of rockfalls. Experiments in quarry areas [PDF]
, 2018 Le frane per crollo da ammassi rocciosi fratturati sono tra i processi di instabilità gravitativa che più frequentemente interessano opere antropiche quali tagli su versanti naturali o artificiali, pareti di cava, trincee stradali, autostradali o ...

Resolving a debate over social freedom
The Southern Journal of Philosophy, EarlyView.Abstract When I am unable to drive due to a road blockade, there seems to be a morally relevant difference between a case in which the road is blocked by workers and a case in which the road is blocked by a landslide. Many political philosophers tried to capture this pretheoretical judgment at a more abstract level through the formulation of a concept ...
