Investigation of ∼ 20–40 mHz ULF waves and their driving mechanisms in Mercury's dayside magnetosphere

Ultra-low-frequency (ULF) waves in the  ∼  20–40 mHz range are frequently observed in the Mercury magnetosphere using Mercury Surface Space Environment Geochemistry, and Ranging (MESSENGER) magnetic field data. The majority of these waves have very similar characteristics to the waves likely driven by Kelvin–Helmholtz (KH) ULF waves (which are retained as a subset of the wave events studied in this paper) identified in a previous study. Significant ULF wave activity is observed in the dawn sector of the magnetosphere. This indicates that Mercury KH waves may be more common between 6 and 12 magnetic local time than previously predicted and that magnetospheric ULF waves in the frequency band  ∼ 20–40 mHz can be used as a detection tool for Hermean KH waves

A New Species of Saphonecrus (Hymenoptera, Cynipoidea) Associated With Plant Galls on Castanopsis (Fagaceae) in China

A new cynipid species, Saphonecrus hupingshanensis Liu, Yang, et Zhu, sp. nov. (Hymenoptera: Cynipidae: Synergini), is described from China. This is the first species of the inquilinous tribe Synergini ever known to have an association with chinquapins (Fagaceae: Castanopsis). The biology and implication to species diversity of Cynipidae in eastern and southeast Asia are discussed

Kvalitetssimulering av sågtimmer metoder för rekonstruktion och sönderdelning av stammar

Denna rapport består av två delar Dels en beskrivning av de metoder som använts i projektet "Kvalitetssimulering av sågtimmer" för att, med utgångspunkt i data från de inmätta stammarna, rekonstruera stammarnas inre och yttre struktur tredimensionellt. Dels en beskrivning av de funktioner som det simuleringsprogram, som utvecklats, kan utföra aptering, sågning, kantning, justering samt värdeberäkning av stockar och stammar. D v s sedan stammarna rekonstruerats genomgick de en simulerad sönderdelning. Liksom för de övriga 3 rapporterna i denna serie är målgruppen andra forskare samt utredare och utvecklare hos skogs- och sågverksföretag samt maskinindustri

A look inside the dynamics of trust: a guide for managers

In the United States, federal public land managers are tasked with serving as stewards of land, but also as stewards of the relationships that people have with the land. By assessing the public’s trust in the actions of land managers, insight can be gained into how good of a job managers are doing. This paper outlines a number of factors that influence the public’s trust in managing agencies, and provides suggestions for monitoring the level of trust. The authors suggest that any efforts to increase the public’s trust require the general attentiveness of land managers

On the origin of magnetosheath plasmoids and their relation to magnetosheath jets

We investigate localized magnetosheath and solar wind density enhancements, associated with clear magnetic field changes, and therefore referred to as magnetosheath/solar wind plasmoids, respectively. Using Cluster data, we show that there are two distinct populations of magnetosheath plasmoids, one associated with a decrease of magnetic field strength (diamagnetic plasmoids), and one with an increased magnetic field strength (paramagnetic plasmoids). The diamagnetic magnetosheath plasmoids have scale sizes of the order of 1-10 RE, while the paramagnetic ones are an order of magnitude smaller. The diamagnetic plasmoids are not associated with any change in the magnetosheath plasma flow velocity, and they are classified as embedded plasmoids in the terminology of Karlsson et al. (2012). The paramagnetic plasmoids may either be embedded or associated with increases in flow velocity (fast plasmoids). A search for plasmoids in the pristine solar wind resulted in identification of 62 diamagnetic plasmoids with very similar properties to the magnetosheath diamagnetic plasmoids, making it probable that the solar wind is the source of these structures. No paramagnetic plasmoids are found in the pristine solar wind, indicating that these are instead created at the bow shock or in the magnetosheath. We discuss the relation of the plasmoids to the phenomenon of magnetosheath jets, with which they have many properties in common, and suggest that the paramagnetic plasmoids can be regarded as a subset of these or a closely related phenomenon. We also discuss how the results from this study relate to theories addressing the formation of magnetosheath jets
