Friction of air in small pipes and fittings

The work of Park and Peterson during 1909-10 at the Missouri School of Mines revealed the fact that more data are needed concerning the loss of pressure due to elbows and other fittings of pipes under three inches in size. Accordingly, we decided to undertake the continuation of their work as a thesis. The apparatus used was practically the same as used in the previous thesis --page 1

Preface

1. The issue The present special issue is developed from a workshop entitled Bantu Universals and Variation at the 10th World Congress of African Linguistics (WOCAL10) held online at Leiden University in June 2021. It includes a selection of papers presented at the workshop, as well as papers submitted in response to an open call for papers. The resultant special issue brings together new perspectives on universals and variation in the Bantu language family, with regards to morphosyntax, sema..

Bantu word order between discourse and syntactic relations

Discourse function has often been noticed to be a strong factor in conditioning Bantu word order. The importance of discourse function for determining the word order of Bantu languages is visible for example in locative inversion and dedicated focus positions. As a result of such phenomena, it has been proposed that Bantu word order is best captured by reference to discourse roles, e.g. Topic-Verb-Nontopic. Nevertheless, we typically see statements describing Bantu word order in relation to grammatical roles (e.g. “SVO”), and the notions “subject” and “object” remain core in analyses of Bantu. In this paper we present the result of a study reconsidering Bantu word order from a discourse-configurational perspective, asking how far we can get without reference to grammatical roles. We use a parametric approach to investigate this syntactic variation, presenting new discourse-oriented field data collected on 9 Bantu languages. We show how these parameters highlight variation within the family, with each language sitting at a different point on a continuum between grammatical role-oriented and discourse role-oriented. We therefore argue against a one-size-fits-all account of Bantu word order and advocate for approaches that include both grammatical and discourse roles.La fonction discursive a souvent été identifiée comme un facteur important dans le conditionnement de l’ordre des mots en bantou. L’importance de la fonction discursive dans la détermination de l’ordre des mots des langues bantoues est visible par exemple dans l’inversion locative et les positions du focus. À la suite de tels phénomènes, il a été proposé que l’ordre des mots en bantou est mieux représenté par les rôles discursifs, par ex. Topique-Verbe-Non-topique. Néanmoins, nous observons généralement des déclarations décrivant l’ordre des mots bantou par rapport aux rôles grammaticaux (par exemple « SVO »), et les notions de « sujet » et « objet » restent au cœur des analyses du bantou. Dans cet article, nous présentons les résultats d’une étude reconsidérant l’ordre des mots bantou dans une perspective des configurations discursives, en nous demandant jusqu’où nous pouvons aller sans référence aux rôles grammaticaux. Nous utilisons une approche paramétrique pour étudier cette variation syntaxique, en présentant de nouvelles données de terrain, axées sur le discours, recueillies sur 9 langues bantoues. Nous montrons comment ces paramètres mettent en évidence la variation au sein de la famille, chaque langue se situant à un point différent sur un continuum entre les rôles grammaticaux et les rôles discursifs. Nous nous opposons donc à une description unique de l’ordre des mots bantou et préconisons des approches qui incluent à la fois les rôles grammaticaux et discursifs

Aberrant development corrected in adult-onset Huntington's disease iPSC-derived neuronal cultures via WNT signaling modulation

Aberrant neuronal development and the persistence of mitotic cellular populations have been implicated in a multitude of neurological disorders, including Huntington's disease (HD). However, the mechanism underlying this potential pathology remains unclear. We used a modified protocol to differentiate induced pluripotent stem cells (iPSCs) from HD patients and unaffected controls into neuronal cultures enriched for medium spiny neurons, the cell type most affected in HD. We performed single-cell and bulk transcriptomic and epigenomic analyses and demonstrated that a persistent cyclin D1+ neural stem cell (NSC) population is observed selectively in adult-onset HD iPSCs during differentiation. Treatment with a WNT inhibitor abrogates this NSC population while preserving neurons. Taken together, our findings identify a mechanism that may promote aberrant neurodevelopment and adult neurogenesis in adult-onset HD striatal neurons with the potential for therapeutic compensation

BioTIME: A database of biodiversity time series for the Anthropocene.

MotivationThe BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These data enable users to calculate temporal trends in biodiversity within and amongst assemblages using a broad range of metrics. BioTIME is being developed as a community-led open-source database of biodiversity time series. Our goal is to accelerate and facilitate quantitative analysis of temporal patterns of biodiversity in the Anthropocene.Main types of variables includedThe database contains 8,777,413 species abundance records, from assemblages consistently sampled for a minimum of 2 years, which need not necessarily be consecutive. In addition, the database contains metadata relating to sampling methodology and contextual information about each record.Spatial location and grainBioTIME is a global database of 547,161 unique sampling locations spanning the marine, freshwater and terrestrial realms. Grain size varies across datasets from 0.0000000158 km2 (158 cm2) to 100 km2 (1,000,000,000,000 cm2).Time period and grainBioTIME records span from 1874 to 2016. The minimal temporal grain across all datasets in BioTIME is a year.Major taxa and level of measurementBioTIME includes data from 44,440 species across the plant and animal kingdoms, ranging from plants, plankton and terrestrial invertebrates to small and large vertebrates.Software format.csv and .SQL
