Review of the Salpausselkä ice‐marginal formations in Finland

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Extensive Salpausselkä ice‐marginal formations were deposited in southern and eastern Finland during the Weichselian deglaciation. These comprise three major ridges (I, II, and III Salpausselkäs) and their eastern counterparts (Tuupovaara, Koitere, and Pielisjärvi), together forming laterally continuous ice‐marginal formations extending ...

Effect of bio‐fertilization and edapho‐climatic conditions on chickpea nodulation, grain yields, and seed protein in a Mediterranean context: a meta‐analysis approach

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract Chickpeas (Cicer arietinum L.) serve as a protein‐rich staple, particularly in Mediterranean countries, where they are often grown in marginal and water‐stressed areas. This meta‐analysis synthesized evidence from peer‐reviewed publications across Mediterranean countries to assess how chickpea rhizobial inoculation influences chickpea ...

A Statistic Study of Airborne Pollen Grains

open access: yesYAKUGAKU ZASSHI, 2000
Since 1969, authors have been doing a statistical analysis of airborne pollen grains, aiming at the clarification of their atmospheric behaviors, in connection with an increase in a number of pollinosis cases. The airborne pollens were collected three times a week starting from January 1 and ending December 31 with the help of cascade impactor, by ...
