Abstract Graphite in metasedimentary rocks of the Eoarchean Saglek-Hebron Gneiss Complex (copyright) is depleted in 13C and has been interpreted as one of the oldest traces of life on Earth.The variation in crystallinity of this oldest graphitic carbon could possibly confirm the effect of metamorphism on original biomass, but this is still unexplor
There has been increasing interest in examining physician well-being and its predictive factors.However, few studies have revealed the characteristics associated with physician well-being and work-life integration using a machine learning approach.To investigate predictive factors of well-being and obtain insights into work-life integration, the su
Road traffic is the most orb grinder used kind of transportation which has a lot of benefits.Except of these benefits, the road traffic causes a lot of negative impacts like a congestions, air pollution and noise.The proposal of European Parliament is reduction of these impacts by their inclusion to the road charges.In the annex of amending directi
Investigations into the spatial dynamics of soil aggregate stability (AS) are urgently needed to better target areas that have undergone soil degradation.However, due to the lack of efficient alternatives to the conventional labor-intensive methods to quantify AS, detailed information on its spatial structure across scales are scarce.The objective
BACKGROUND: Sequence analysis is a set of tools increasingly used in demography sapatilha infantil prata glitter and other social sciences to analyse longitudinal categorical data.Typically, single (e.g., education trajectories) or multiple parallel temporal processes (e.g., work and family) are analysed by using crisp clustering algorithms that re
