Early means of maintaining soil fertility included intercropping, crop rotations that included legumes, fallowing, manuring, and the addition of ash. By using these techniques some societies developed sustainable agricultural systems that persisted for thousands of years. However, human management has ...
Our plant dataset is consistent with Willerslev et al.33in which forbs were found to proportionally dominate their metabarcoded sedaDNA signal during and after the LGM. Nichols et al.112argue that the forb dominance observed in Willerslev et al.33was partly caused by polymerase and GC biases ...
serious hypokalemia and hyperthyroidism.Rechargeable lithium-ion electric batteries are vital to contemporary energy storage, yet current anode material systems find it difficult to meet with the increasing interest in extended range capabilities. This work presents a novel composite anode material made up...
with their respective concentrations being 21% and 22%. Additionally, other detected elements such as Na, Mg, Al, Si, S, and Ca can be attributed to the wood material and the long-term burial environment, during which elements from the surrounding soil, ...
Polygonaceae, alpha level = 0.025; Ranunculaceae, alpha level = 0.025; Orobanchaceae, alpha level = 0.05, Supplementary Table 4), supporting the idea that soil development contributes to the coexistence of a large number of plant species30. However, it is not the key driver for the total...
(e.g. soil). Overall, the calculus samples of all analysed individuals (independently of the sex, age at death or diseases) had a taxonomic composition similar to what has been previously found in other ancient calculus studies [6,11,13] and a major proportion of the discovered ...
(2002) analyzed the stability of two systems of bell-shaped caverns excavated about 1000 years ago at Bet Guvrin National Park. Their results were obtained using a continuum model framework (i.e. FLAC) and a discontinuous approach (i.e. block theory). After that, Tsesarsky et al. (2013...
Scholars have tried to locate historical evidence for the existence and nature ofvarnaandjatiin documents and inscriptions of medieval India. Supporting evidence for the existence ofvarnaandjatisystems in medieval India has been elusive, and contradicting evidence has emerged. ...
it aims to highlight how far research on glass corrosion has come by studying model systems created in the laboratory to simulate different alteration conditions and glass compositions. On the other, it seeks to point out what are the critical aspects that still need to be investigated and how...
Other, summed proportions across non-oral microbial groups (non-oral human microbiome, air, and soil) and unknown classification. Groups have a minimum of two samples (the non-human primate group is removed in filtered analysis as filtering reduced the sample number to one) and are displayed ...
