Cryogenic adhesives and sealants: Abstracted publications

Abstracts of primary documents containing original experimental data on the properties of adhesives and sealants at cryogenic temperatures are presented. The most important references mentioned in each document are cited. In addition, a brief annotation is given for documents considered secondary in nature, such as republications or variations of original reports, progress reports leading to final reports included as primary documents, and experimental data on adhesive properties at temperatures between about 130 K and room temperature

Fresh Water Mollusks of the Grassy Butte Area McKenzie County, North Dakota

Eight molluscan species consisting of 92 specimens from six localities in the Grassy Butte area of North Dakota are here identified and located stratigraphically. The genera identified are Viviparus, Lioplacodes, Campeloma, and Reesidella. These fauna come from the Tongue River formation and the Sentinel Butte member of the Tongue River formation of upper Paleocene time

Faking it for the higher-ups: Status and surface acting in workplace meetings

Recent evidence suggests that surface acting occurs in workplace meetings. Even in light of these findings, it remains unknown why employees would choose to surface act in meetings with their colleagues and supervisors, and how this form of emotion regulation affects employees in the short-term. A sample of working adults were asked to report their levels of surface acting during multiple workplace meetings. Results indicate that employees engage in surface acting during meetings, and that their surface acting is positively related to the presence of higher-status attendees in these meetings. Additionally, surface acting during meetings is negatively related to perceptions of both meeting psychological safety and meeting effectiveness. We also highlight the important role of one’s job level as a moderating condition when examining the relationship between surface acting and perceived meeting effectiveness. Our results suggest that individuals who are higher-up in an organization’s hierarchy may perceive meetings as less effective when they surface act when compared to individuals who are in lower levels of the organization

Hopf Bifurcation and Chaos in a Single Inertial Neuron Model with Time Delay

A delayed differential equation modelling a single neuron with inertial term is considered in this paper. Hopf bifurcation is studied by using the normal form theory of retarded functional differential equations. When adopting a nonmonotonic activation function, chaotic behavior is observed. Phase plots, waveform plots, and power spectra are presented to confirm the chaoticity.Comment: 12 pages, 7 figure

Vitis flower types: from the wild to crop plants

Vitis vinifera can be divided into two subspecies, V. vinifera subsp. vinifera, one of the most important agricultural crops in the world, and its wild ancestor, V. vinifera subsp. sylvestris. Three flower types can be observed: hermaphrodite and female (on some varieties) in vinifera, and male or female flowers in sylvestris. It is assumed that the different flower types in the wild ancestor arose through specific floral patterns of organ abortion. A considerable amount of data about the diversity of sexual systems in grapevines has been collected over the past century. Several grapevine breeding studies led to the hypothesis that dioecy in vinifera is derived from a hermaphrodite ancestor and could be controlled by either, one or two linked genetic determinants following Mendelian inherence. More recently, experiments using molecular approaches suggested that these loci were located in a specific region of the chromosome 2 of vinifera. Based on the works published so far, its seems evident that a putative sex locus is present in chromosome 2. However, it is still not fully elucidated whether flower types are regulated by two linked loci or by one locus with three alleles. Nevertheless, several genes could contribute to sex determination in grapevine. This review presents the results from early studies, combined with the recent molecular approaches, which may contribute to the design of new experiments towards a better understanding of the sex inheritance in grapevine.This work was supported by the funded project PTDC/AGR-GPL/119298/2010 from Fundacao para a Ciencia e Tecnologia (FCT, Portugal), by UID/AGR/04129/2013 centre grant from FCT, Portugal (to LEAF) and by PEst-OE/BIA/UI4046/2014; UID/MULTI/04046/2013 centre grant from FCT, Portugal (to BioISI) and are supported by FCT fellowships JL Coito, MJN Ramos, H Silva, M Rocheta, respectively, SFRH/BD/85824/2012, SFRH/BD/110274/2015, SFRH/BD/111529/2015, SFRH/BPD/64905/2009.
