Mineral acquisition from clay by Budongo Forest chimpanzees
Full text linkDate of Acceptance: 06/07/2015Chimpanzees of the Sonso community, Budongo Forest, Uganda were observed eating clay and drinking clay-water from waterholes. We show that clay, clay-rich water, and clay obtained with leaf sponges, provide a range of minerals in different concentrations. The presence of aluminium in the clay consumed indicates that it takes the form of kaolinite. We discuss the contribution of clay geophagy to the mineral intake of the Sonso chimpanzees and show that clay eaten using leaf sponges is particularly rich in minerals. We show that termite mound soil, also regularly consumed, is rich in minerals. We discuss the frequency of clay and termite soil geophagy in the context of the disappearance from Budongo Forest of a formerly rich source of minerals, the decaying pith of Raphia farinifera palms.Peer reviewe
Spiritual Interrogations : Culture, Gender, and Community in Early African American Women's Writing /
No full textThe late eighteenth century witnessed an influx of black women to the slave-trading ports of the American Northeast. The formation of an early African American community, bound together by shared experiences and spiritual values, owed much to these women's voices. The significance of their writings would be profound for all African Americans' sense of their own identity as a people. Katherine Clay Bassard's book is the first detailed account of pre-Emancipation writings from the period of 1760 to 1863, in light of a developing African American religious culture and emerging free black communities. Her study--which examines the relationship among race, culture, and community--focuses on four women: the poet Phillis Wheatley and poet and essayist Ann Plato, both Congregationalists; and the itinerant preacher Jarena Lee, and Shaker eldress Rebecca Cox Jackson, who, with Lee, had connections with African Methodism. Together, these women drew on what Bassard calls a "spirituals matrix," which transformed existing literary genres to accommodate the spiritual music and sacred rituals tied to the African diaspora. Bassard's important illumination of these writers resurrects their path-breaking work. They were cocreators, with all black women who followed, of African American intellectual life.The late eighteenth century witnessed an influx of black women to the slave-trading ports of the American Northeast.

Guide to the nature and methods of analysis of the clay fraction of tephras from the South Auckland region, New Zealand.
No full textThe manual outlines some of the more common laboratory procedures available for qualitatively and quantitatively analysing the composition of the tephric clays, many of which are difficult to determine because of their short range order or 'amorphous' nature. Techniques described and assessed in terms of their rapidity and quantitativeness include XRD, IR, DTA, TEM and SEM, sodium fluoride reactivity, chemical dissolution analyses, and surface area measurements. No one technique alone produces a definitive clay fraction analysis of tephric deposits. -from Author

From Penrith to Paris
Full text linkKatherine Clay has written her first graphic novel, 'From Penrith to Paris', based on experiences of her first semester in France. It deals with the issues of student life, the loss of cultural identity through language and what it means to come from the cultural wasteland of Sydney to the cultural capital of the world - Paris. Through these funny and often life changing experiences, she realises the value of her hometown and that culture, no matter how it is perceived, plays an enormous role in the shaping of individuals
Collective effects on the settling of clay flocs
No full textIn this work a high-magnification digital video camera in combination with a settling column is used to study in a first part the influence of the amount of flocs transferred into the settling column on their settling velocity. In a second part, the setup was used to study the properties of flocs prepared at different clay concentrations but at same flocculant to clay ratio (2.5mgg−1). Illite clay was used and flocculated in a 1 L jar with an anionic polyacrylamide (flocculant). Results show that the average settling velocity of flocs is a function of the amount of transferred flocs. It was also found that floc size and settling velocity depend on clay concentration. This is attributed to the fast aggregation happening in the jar when flocculant and clay are mixed: at higher clay concentrations, larger flocs are created in the first minutes of the experiment, with low densities that prevent them from settling to the bottom of the jar.Environmental Fluid MechanicsRivers, Ports, Waterways and Dredging Engineerin
Katherine L. Ross Artist Lecture
No full textKatherine L. Ross is interested in clay’s physical presence in the natural world, its role in economies, politics and culture throughout history and its obsolescence in contemporary culture. She will be showing two installations at The Peeler Art Center that address very different aspects of these interests. Porcelain intrigues her more than any other type of clay because of its history. Porcelain is a status symbol valued for purity and strength. It is elegant and expensive but also used at the dinner table of families across the globe. “The Tzetzegov Erasures” is an installation developed from research on propaganda porcelain produced at the Lomonosov (formerly the State) Porcelain Factory in St. Petersburg, Russia and research at the KGB archives in St. Petersburg. This was the scene of a dramatic transition from the production of Imperial Czarist porcelain to porcelain used as an element of systematic revolutionary propaganda and the discovery of a personal family connection to this history. Related to this interest in art used for propaganda and agitprop, she is interested in the Stalinist-era commissioning of artists to re-cast revolutionary history. Rodchenko was one artist of many enlisted to falsify photographs and documents. Government directives commanded all citizens to alter their personal archives to eliminate any references to persons who had been exiled or executed. This installation examines her family history. It is the revelation of an erased family member. Influences for this body of work include Carl Andre’s 1960’s poetry and his strategies of isolation, removal, and fragmentation to examine war and cultural eradication. Re-examining specific historical records draw parallels to current political conflicts. The second installation, “The Unseen and Misremembered” is a poetic examination of what we know, see and remember of the physical world around us. Much of the natural world is concealed or obscured from us. We think we know. Katherine explained, “I think I know clay. I walk over the clay under my house and the clay under all of Chicago every day but it is unseen. I stripped away all of the vegetation in the field by my barn and exposed the clay surface I have never seen. I strapped a video camera under the belly of my mule and rode her all over that field. With every step the clay flew into the air. I replanted the field and don’t see the clay anymore.” Clay/soil borings are pipes driven 30 to 40 feet into the clay ground. Pipes filled with clay to be tested before a skyscraper is built on top of it. We never see the exposed clay in Chicago. Encyclopedias were written to record and explain everything. Hundreds of years ago scientists travelled the earth in search of the unknown and unseen. One returned to France, hired an artist to draw the animals from his description for the encyclopedia he was writing. Misremembered or inaccurately explained, the artist drew the mule.” Both installations are a search for ultimately understanding the unknown.https://scholarship.depauw.edu/peeler_event/1077/thumbnail.jp
Data supporting Inhibition of the Growth of Harmful Algal Bloom-forming Freshwater Cyanobacteria by Clay
No full textThis dataset contains cell density measurements and confocal images of Microcystis Aeruginosa. The raw data from hand counting cells under a microscope with a hemocytometer is included, as well as the calculated cell density based on the hemocytometer measurements. The bacteria cells were grown in one of three growth conditions. Each growth condition was simulated in three different flasks. For each date, the cell densities of identical growth conditions were averaged. Cell densities for each date and growth condition were subsequently plotted with error bars to determine any trends. Additionally, data on the environmental conditions of cell growth are included on dates when the measurements were taken.
The physical interactions between cyanobacteria and clay particles were visualized using a confocal laser scanning microscope (Nikon C2 plus). Each image is around 2048 by 2048 pixels at a resolution of 0.08 um/pixel. We used a 20X objective magnification. A sequence of images was taken at 10-second intervals for 5 minutes. The laser used for excitation has a wavelength of 488 nm (FITC) and the emission wavelength is 525 nm.This study was supported by JQ Yang’s startup funds and University of Minnesota’s MnDRIVE Environment seed grantYang, Judy Q; Tomaska, Katherine R; Wei, Guanju.

Clay micromechanics: experimental challenges and perspectives
No full textThe importance of physico-chemical processes at the particle scale for the engineering scale behaviour of fine-grained geomaterials is undisputed. Yet, despite great advances in the discipline, experimental evidence that fully resolves the clay micromechanics i.e. linking the evolving microstructure and interparticle actions under loading, is lacking. This paper will discuss the challenges ahead in quantifying the evolving kinematics and interparticle interactions of finegrained geomaterials. As such, the current limitations, and the potential opportunities of experimental methodologies for manipulating, monitoring and (post-mortem) analysing fine-grained materials at the particle scale will be discussed. In addition to the need of integrating multiple experimental techniques that span several length scales and modalities, the critical role of advanced data reduction and analysis is highlighted, as required for a measurement as opposed to qualitative observation. Throughout the paper, the link between experimental clay micromechanics and modelling will be discussed.Geo-engineerin
