In archaeology, lithic analysis is the analysis of stone tools and other chipped stone artifacts using basic scientific techniques. At its most basic level, lithic analyses involve an analysis of the artifact's morphology, the measurement of various physical attributes, and examining other visible features (such as noting the presence or absence of cortex, for example).
While many worked stone tools can be technically designated as "modified flakes," for lithic analysis purposes a modified flake is usually defined as a lithic flake with one or more edges that were altered either through opportunistic use or through nonsystematic retouching; it is often difficult to identify the process that produced the observed edge.
Seismic performance assessment or seismic structural analysis is a powerful tool of earthquake engineering which utilizes detailed modelling of the structure together with methods of structural analysis to gain a better understanding of seismic performance of building and non-building structures. The technique as a formal concept is a ...
The earliest stone tools to date have been found at the site of Lomekwi 3 (LOM3) in Kenya and they have been dated to around 3.3 million years ago. [1] The archaeological record of lithic technology is divided into three major time periods: the Paleolithic (Old Stone Age), Mesolithic (Middle Stone Age), and Neolithic (New Stone Age).
A risk evaluation means that judgements are made on the tolerability of the identified risks, leading to risk acceptance. When risk analysis and risk evaluation are made at the same time, it is called risk assessment. [1] As of 2023, chemical risk assessment follows these 4 steps: [4] hazard characterization; exposure assessment; dose-response ...
Some claim that they can determine the sort of tools used to create the debitage. Others feel it is possible to effectively estimate the work-hours represented, or the skill of the workers based on the nature of the debitage. Debitage analysis of biface reduction can be used to determine what stage of reduction is represented in waste.
The building was vacant at the time and the fires were quickly extinguished by members of the North Providence Police and Fire departments, investigators said. The fires caused property damage.
A group of building experts published the Stone Tower Research Project showing that construction of a 30-storey skyscraper office block with a combination of an MP-stone load-bearing exoskeleton and post-tensioned stone flooring panels would cost less than the same building in concrete. [16]
