Existence of entire solutions for Schrödinger–Hardy systems involving two fractional operators
No full textThis paper deals with the existence of nontrivial nonnegative solutions of Schrödinger-Hardy systems driven by two possibly different
fractional p-Laplacian operators, via various variational methods. The main features of the paper are the presence of the Hardy terms
and the fact that the nonlinearities do not necessarily satisfy the Ambrosetti--Rabinowitz condition. Moreover, we consider systems including critical nonlinear terms, as treated very recently in literature, and present radial versions of the main theorems. Finally, we briefly show how to extend the previous results when the fractional Laplacian operators are replaced by more general elliptic nonlocal integro-differential operators
Multiple Solutions for an Eigenvalue Problem Involving Non-local Elliptic p-Laplacian Operators
No full textIn this paper we establish the existence of two nontrivial weak solutions of a one parameter non-local eigenvalue problem under homogeneous Dirichlet boundary conditions in bounded regular domains, involving a general non-local elliptic p-Laplacian operator

Sara Gossett Crigler Collection - Accession 614
No full textThe Sara Gossett Crigler Collection consists of a microfiche copy of her book titled, Education For Girls And Women In Upper South Carolina Prior to 1890 with Related Miscellaneous Articles: A Compilation by Mrs. Henry Towles Crigler (Sara Gossett Crigler), self-published in Greenville, SC on April 15, 1956. This book also includes many anecdotes and reminiscences of Sara’ family including a section devoted to the slaves owned and later freed after the Civil War by her family. The book is dedicated by the author, Sara Gossett Crigler (1886-1966), to her mother Sallie Brown Gossett (1859-1942) and her aunt Mary Brown Mahon (1861-1948) who were both graduates of Williamston Female College in 1877 and 1879 respectively. The 170 page volume would be useful to anyone doing research on the education of women in South Carolina during the 19th century. The original copy is housed at the South Carolina Historical Society as SCHS 509 and was dedicated and signed by the author, “For the Charleston Library Society” on July 10, 1964.

SALDI Substrate-Based FeNi Magnetic Alloy Nanoparticles for Forensic Analysis of Poisons in Human Serum
No full textIn this study, FeNi magnetic alloy nanoparticles (MANPs) were employed for the forensic analysis of four poisons—dimethametryn, napropamide, thiodicarb, and strychnine—using surface-assisted laser desorption/ionization mass spectrometry (SALDI-MS). FeNi MANPs were prepared via coprecipitation using two reducing agents, sodium borohydride (NaBH(4)) and hydrazine monohydrate (N(2)H(4)·H(2)O), to optimize the prepared MANPs and investigate their effect on the performance of SALDI-MS analysis. Thereafter, SALDI-MS analysis was carried out for the detection of three pesticides and a rodenticide. The prepared substrate offered sensitive detection of the targeted analytes with LOD values of 1 ng/mL, 100 pg/mL, 10 ng/mL, and 200 ng/mL for dimethametryn, napropamide, thiodicarb, and strychnine, respectively. The relative standard deviation (%RSD) values were in the range of 2.30–13.97% for the pesticides and 15–23.81% for strychnine, demonstrating the good spot-to-spot reproducibility of the FeNi substrate. Finally, the MANPs were successfully employed in the analysis of poison-spiked blood serum using a minute quantity of the sample with an LOD of 700 ng/mL dimethametryn and napropamide, 800 ng/mL thiodicarb, and 500 ng/mL strychnine. This study has great potential regarding the analysis of several poisons that may be found in human serum, which is significant in cases of self-harm
Materia-autore = Author-Matter
No full textThe etymology of the word author refers to an act of creation, an act of augmentation, from the Latin verb augere. Author instantiates creation, the expansion of the pre-existing. In 1967 Roland Barthes declared the death of the author in his famous essay to state once more that the crisis is that of the author as a single subjectivity and as a term that condenses prestige, undermined by the de-subjectivation strategies of automatism, fortuity and fragmentation of the historical avant-gardes, as well as by the machinic act and by the reproducibility of the second avant-gardes.
Fifty years after Barthes’ paradigmatic formula, this lack of authorship appears to be a successful brand. The ten- sions between the anomie of matter, the law that establishes authorship and the economy that makes the work pos- sible, invoke discordant perspectives. Artists make the self-destruction of their work the real work, and appeal is made for the demolition of architectures, whether by a recognised author or not, in order to re-design, or better still, re-claim the territory. Artificial intelligence consolidates its logics and its design by progressively shedding human ingenuity. The space of criticism becomes, finally, increasingly ephemeral. However, there is an acceptation of criti- cism that is, rather than an individual ‘signature’, an exploration and explanation of how design makes theory.
The binomial author-matter seeks to mark these tensions and contradictions: the featured term author is main- tained to underline the persistence of that prestigious subjectivity, at the very moment when the rhetoric of “mat- ter as an author” promises other forms of authorship
Sara Winthrop Smith letter to Frances Casement, August 14, 1887
No full textLetter written to Frances Casement from Sara Winthrop Smith of Cincinnati, Ohio, August 14, 1887. Winthrop expresses the challenges of generating support for the suffrage movement among the conservative residents of her city, and encourages the creation of clear materials that make the argument for women's suffrage to be more widely distributed.
This item comes from the Frances Jennings Casement Papers, a manuscript collection comprised of letters and association records related to the founding and leadership of the Ohio Woman Suffrage Association. Casement (1840-1928) was born in Painesville, Ohio, and graduated from Painesville Academy and Willoughby Female Seminary. Her father, Charles Casement, supported abolition and women's suffrage and encouraged Frances to be active in social causes. Frances Casement established the Painesville Equal Rights Association in 1883, and shortly after became involved in the Ohio Woman Suffrage Association, serving as its president from 1885 to 1888
