Rietveld refinement of the Tutton salt K-2[Fe(H2O)(6)](SO4)(2)
No full textDipotassium hexaaquairon(II) bis( sulfate), K-2[Fe(H2O)(6)]-( SO4)(2), is a member of the isotypic series of Tutton salts with general formula M-2(I)[M-II(H2O)(6)](XO4)(2), where X = S, Se or Cr. The structure contains centrosymmetric Fe(H2O)(6) octahedra, with an average Fe-O distance of 2.14 (4) angstrom. Each octahedron is surrounded by isolated SO4 tetrahedra [average S-O distance = 1.483 (15)angstrom] and distorted KO6(H2O)(2) polyhedra with an average K-O distance of 2.96 (15) angstrom. The polyhedra are linked via common O atoms and a system of medium-strength hydrogen bonds

Vertebroplasty using transoral approach in painful malignant involvement of the second cervical vertebra (C2): a single-institution series of 25 patients
No full textVertebroplasty is a minimally invasive procedure demonstrated to be safe and effective in the treatment of painful osteoporotic and malignancy related fractures when performed in the thoracolumbar spine. Multiple randomized and nonrandomized reports have demonstrated its effectiveness. Conversely, transoral vertebroplasty (TOV) to treat the second cervical vertebra (C2) has been described in only a few case reports

The M&G Drive
No full textabstract: The M&G Drive is a proposed venture project lead by Barrett seniors, Elijah Smith and Jenna Fitzgerald. This project aims to educate Arizona State University (ASU) students on the issues of food insecurity around the Phoenix valley and facilitate their involvement in helping alleviate this pressing social matter. Scientific research has shown significant inverse relationships between food insecurity and the following: mental and physical health, social skills, and academic achievement. As the largest public university in the nation, Arizona State holds a self-ascribed responsibility for the health of its communities. In order to address this issue on behalf of Arizona State and from the standpoint of college students, this proposed venture will encourage the ASU student population to reallocate their unused M&G Dollars (ASU’s on-campus currency) to go toward this cause. Rather than being absorbed back by the university system, unused M&G Dollars can instead be used to purchase non-perishables that will then be donated to the local Phoenix community in order to help fight against food insecurity
Lah–Ribarič type inequalities for (h, g; m)-convex functions
No full textRecently introduced new class of (h, g; m)-convex functions unifies a certain range of convexity, thus allowing the generalizations of know results. In this paper we prove Lah–Ribarič type inequalities for (h, g; m)-convex functions from which we obtain inequalities of Hermite–Hadamard, Fejér, Giaccardi, Popoviciu and Petrović. © 2021, The Author(s) under exclusive licence to The Royal Academy of Sciences, Madrid

Temperature-Induced Phase Transformations in Tutton Salt K2Cu(SO4)2(H2O)6: Thermoanalytical Studies Combined with Powder X-Ray Diffraction
No full textTutton salts have received considerable attention due to their potential applications in thermochemical energy storage (TCHS) systems. This technology requires high-purity materials that exhibit reversible dehydration reactions, significant variations in dehydration enthalpy, and high-temperature melting points. In this study, K2Cu(SO4)2(H2O)6 Tutton salt in the form of single crystals was grown using the slow solvent evaporation method. Their structural, morphological, and thermal characteristics are presented and discussed, as well as temperature-induced phase transformations. At room temperature, the salt crystallizes in a monoclinic structure belonging to the P21/a space group, which is typical for Tutton salts. The lack of precise control over the solvent evaporation rate during crystal growth introduced structural disorder, resulting in defects on the crystal surface, including layer discontinuities, occlusions, and pores. Thermoanalytical analyses revealed two stages of mass loss, corresponding to the release of 4 + 2 coordinated H2O molecules—four weakly coordinated and two strongly coordinated to the copper. The estimated dehydration enthalpy was ≈ 80.8 kJ/mol per mole of H2O. Powder X-ray diffraction measurements as a function of temperature showed two phase transformations associated with the complete dehydration of the starting salt occurring between 28 and 160 °C, further corroborating the thermal results. The total dehydration up to ≈ 160 °C, high enthalpy associated with this process, and high melting point temperature make K2Cu(SO4)2(H2O)6 a promising candidate for TCHS applications
Representative Bureaucracy and the Willingness to Coproduce: An Experimental Study
No full textRelying on the theory of representative bureaucracy—specifically, the notion of symbolic representation—this article examines whether varying the number of female public officials overseeing a local recycling program influences citizens’ (especially women's) willingness to cooperate with the government by recycling, thus coproducing important policy outcomes. Using a survey experiment in which the first names of public officials are manipulated, the authors find a clear pattern of increasing willingness on the part of women to coproduce when female names are more represented in the agency responsible for recycling, particularly with respect to the more difficult task of composting food waste. Overall, men in the experiment were less willing to coproduce across all measures and less responsive to the gender balance of names. These findings have important implications for the theory of representative bureaucracy and for efforts to promote the coproduction of public services.This is the peer reviewed version of the following article: Riccucci, Norma M., Van Ryzin, Gregg G. & Li, Huafang.
