Performance of gravel aggregates in superpave mixes with 100/95 angularity
No full textThe current aggregate requirement for aggregate angularity that the NYSDOT requires for their Superpave Hot Mix Asphalt (HMA) is 100/98. With this requirement, many of the gravel quarries in New York State cannot meet that specification. As a result, quarries that are further away from the job site have to transport the aggregates which in turn increases the cost of construction. This paper investigates a multitude of test methods to determine whether the NYSDOT can further lower their Superpave aggregate angularity requirement. Also, this paper delves into "grade bumping".M.S.Includes bibliographical referencesIncludes abstractby Christopher L. Ericso
Makilingia frontalis Baker 1924
No full textMakilingia frontalis Baker (Figs 1 L–M, 4Z–DD, 8D, 9G–H) Makilingia frontalis Baker, 1924: 69. Fig. 15 Male genitalia. Pygofer with ventral appendage elongate, narrow basally broadened and bent dorsad beyond margin of lobe, apex tapered and extended beyond lobe by more than half length of lobe. Subgenital plate relatively long, basal sclerotized section relatively short and narrow, distal lobe long and broad, curved slightly dorsad and compressed, dorsal callosity relatively small. Style with preapical lobe broad, angulate, distinctly angulate preapical heel present. Aedeagus with preatrium nearly as long as shaft, in lateral view bent at right angle, shaft compressed, broad in lateral view, apex irregularly rounded; in posterior view with preatrium narrow and slightly constricted medially, atrium with pair of large irregularly rounded lateral denticulate flanges, shaft nearly parallelsided to rounded apex. Female. Sternite VII nearly twice as wide as long, posterior margin with pair of narrow acute projections flanking shorter rounded medial lobe. Second valvulae with dorsal margin nearly straight through most of length, somewhat broadened near apex and obliquely truncate, teeth prominent, numerous, rounded and somewhat irregularly spaced. Material examined. Lectotype male, here designated, labeled: " Davao / Mindanao / Baker; Cotype / U.S. N.M.; LECTOTYPE / Makilingia / frontalis Baker / des. CH Dietrich / & JN Zahniser 2019; USNMENT / 01513296". 2 female paralectotypes, first two labels with same data, additionally labeled “ PARALECTOTYPE / Makilingia / frontalis Baker / des. CH Dietrich / & JN Zahniser 2019”; each with a USNMENT barcode label numbered 0 1513297 thru 01513298; 1 additionally labeled “20442" (USNM). Notes. A male cotype from Baker's type series in the USNM is here designated lectotype to fix the identity of the species. This species resembles M. costalis in having the dorsum uniformly black except for the pale costal margin of the forewing but differs in having the texture of the face between the punctures glabrous rather than shagreen.Published as part of Dietrich, Christopher H. & Zahniser, James N., 2019, Review of the leafhopper genus Makilingia Baker (Hemiptera: Cicadellidae: Mileewinae), pp. 473-500 in Zootaxa 4559 (3) on page 483, DOI: 10.11646/zootaxa.4559.3.3, http://zenodo.org/record/262715
Cediopsylla simplex Baker

L. Boke (Fox 1940); 1 F, TN, Blount Co., 20 Nov. 1947, D. W. Pfitzer (Pfitzer 1950, Benton 1980, Durden & Kollars 1997). As indicated by its vernacular name, the rabbit flea mainly parasitizes lagomorphs (Durden & Kollars 1997). This flea also forms shortterm associations with predators of lagomorphs, such as foxes and dogs (Durden et al. 2005).Published as part of Reeves, Will K., Durden, Lance A., Ritzi, Christopher M., Beckham, Katy R., Super, Paul E & Oconnor, Barry M., 2007, Ectoparasites and other ectosymbiotic arthropods of vertebrates in the Great Smoky Mountains National Park, USA, pp. 31-68 in Zootaxa 1392 on page 43, DOI: 10.5281/zenodo.27368

Christopher Dawson
No full textInspired with Jude P. Dougherty’s works in which he stresses the overruling importance of the classical, humanistic education and the central place and role of religion in the Western culture, the author presents Christopher Dawson’s analysis of the Western civilization and his demonstration of the central role of Christianity in it. The author traces the premises on which was based Dawson’s opinion that modern Western man might be absorbed by his technical inventions, to the point of losing his soul
Culture and religion
No full textCulture is the result of, and is itself expressed through, religion, language, institutions and history. Culture is persistent but does change slowly over time. Religion is either one manifestation of culture or itself shapes that culture. This chapter discusses recent contributions to the economics of culture and religion, a literature which was instigated by economic historians and has long been dominated by their work. Its author especially focuses on the role of culture and religion in engendering industrial progress and institutional change
Epigenetic regulation and transcription factor programming enhances neurogenesis in neural stem cells
No full textIn this thesis, we questioned how neuronal and glial phenotypes become specialized. Epigenetic chromatin modifiers and transcription factors were investigated on their roles in programming and maintaining neural lineage restriction. A relatively homogeneous population of cells was generated by deriving immortalizing neural clones from embryonic rat forebrains. Three phenotypes; neuronal, glial and multipotential (GE6, GE2, CTX8), provided contrasting lineages to probe the factors responsible for shaping cell fate. One particular clone, GE6, differentiated into a functional inhibitory like interneuron. Gene expression analysis showed several genes such as Ascl1, Dlx1, Dlx5, may be responsible for the interneuronal phenotype. Epigenetic regulation through histone modifications is believed to be an essential component within the developing nervous system, ultimately affecting cell fate. Testing chromatin signatures on specific neural genes with permissive and repressive histone “marks” shows that chromatin state in undifferentiated precursors correlates with current and predicts downstream gene expression. These results suggest that cell fate may already be predetermined. Furthermore, ChIP sequencing reveals global differences between the representative clones. Extrinsic growth factors, such as BMP2 promotes the neuronal and glial phenotypes in the multipotential cell CTX8. BMP2 asserts its phenotypic response in part by regulating global acetylation enrichment in specific neural gene networks, providing a mechanism to promote and maintain cell fate. Directly altering chromatin marks using a histone deacetylase inhibitor, valproic acid (VPA), globally acetylates the chromatin of CTX8 cells and enhances neurogenesis. VPA treatment was found to also maintain or increase acetylation in specific neuronal genes, such as Ascl1. In addition, several microRNAs thought to play a role in neurogenesis were also epigenetically regulated after VPA treatment. Finally, through the combination of gene expression and epigenetic analyses, direct programming through exogenous expression of Ascl1, Dlx1 and Dlx5 enhanced neurogenesis in CTX8. Gene expression and epigenetic signature mapping provides us with a deeper understanding of how lineage restriction occurs. Learning the programming rules will assist in directing homogeneous populations of neuronal cells to further probe the mechanisms of neurodegenerative diseases.Ph.
