The Aeolian island of Lipari, just north of eastern Sicily, was a major geological source of high quality obsidian that was volcanically formed in the Late Mesolithic, followed by another major production in the 1st millennium AD.A much earlier volcanic event on Lipari also produced some obsidian, but Activity Equipment not of sufficient quality fo

One of the main requirements of the truck tire sidewall are flexing resistance, tensile strength and tear resistance, as well as resistance to weather conditions experienced by tires during use, which include exposure to sunlight and ultraviolet radiation.Therefore, the requirements and changing circumstances led to develop the design parts of tire

This paper explores the stages of organization and equipping that occurred in the communications of the Romanian army and the creation of the first specialized sub-units, preparation and participation in the War of Independence (1877- 1878) with further developments until the First World War.The study and analysis of Activity Equipment the most sig

Methane is a powerful greenhouse gas with a 25 times higher 100-year warming potential than carbon dioxide and is a target for mitigation to achieve climate goals.To control and curb methane emissions, estimates are required from the sources and sectors which are typically generated using bottom-up methods.However, recent studies have shown that na

The dynamic assembly of filamentous (F) actin plays essential roles in the assembly of presynaptic boutons, the fusion, mobilization and recycling of synaptic vesicles (SVs), and presynaptic forms of plasticity.However, the molecular mechanisms that regulate the temporal and spatial assembly of presynaptic F-actin remain largely unknown.Similar to
