Poly(pyridinium salt)s Containing 9,9-Bis(4- aminophenyl)fluorene Moieties with Various Organic Counterions Exhibiting Both Lyotropic Liquid-Crystalline and Light-Emitting Properties
No full textMain-chain conjugated and non-conjugated polyelectrolytes are an important class of materials that have many technological applications ranging from fire-retardant materials to carbon-nanotube composites, nonlinear optical materials, electrochromic materials for smart windows, and optical sensors for biomolecules. Here, we describe a series of poly(pyridinium salt)s-fluorene containing 9,9-bis(4-aminophenyl)fluorene moieties with various organic counterions that were synthesized using ring-transmutation polymerization and metathesis reactions, which are non-conjugated polyelectrolytes. Their chemical structures were characterized by Fourier transform infrared (FTIR), proton (1H) and fluorine 19 (19F) nuclear magnetic resonance (NMR) spectrometers, and elemental analysis. They exhibited polyelectrolytic behavior in dimethyl sulfoxide. Their lyotropic liquid-crystalline phases were examined by polarizing optical microscopy (POM) and small angle X-ray scattering (SAXS) studies. Their emission spectra exhibited a positive solvatochromism on changing the polarity of solvents. They emitted greenish-yellow lights in polar organic solvents. They formed aggregates in polar aprotic and protic solvents with the addition of water (v/v, 0–90%), whose λem peaks were blue shifted

National Cancer Centers and Cancer Rates in Nevada, 2017-2021
No full textThis fact sheet presents data from the National Institutes of Health including the National Cancer Institute’s (NCI) “State Cancer Profiles” report and includes age-adjusted cancer incidence rates by race/ethnicity in Nevada, between 2017 and 2021. The fact sheet also shows data from the 2024 National Cancer Institute’s “NCI-Designated Cancer Centers” map, listing NCI-Designated Cancer Centers by state, and the distance to the nearest NCI-Designated Cancer Centers from the Las Vegas metro and Reno metro
Rainy Day Funds in Mountain West States, FY2024
No full textThis fact sheet presents data on rainy day funds for fiscal year 2024 in the five Mountain West states of Arizona, Colorado, Nevada, New Mexico, and Utah, as originally reported in the 2025 Governing Magazine article, “Growth of State Rainy Day Funds Has Slowed Down.” These data capture the number of days each state could fund state government operations using only rainy day funds, which represent the money states set aside to maintain operations during economic downturns or fiscal stress
Sweet Snacks Effects on Hispanic/Latino Childhood Obesity
No full textBackground:
Obesity rates in children has become a growing concern in the Hispanic/Latino community in Nevada. This study examines the availability of sweet snacks in the home and its association with children\u27s dietary behavior.
Methods:
Data was analyzed from a survey of 155 Latina mothers using logistic regression while controlling for income, education, and acculturation. The survey was conducted in Nevada, between October 2022 and March 2024.
Results:
The frequency of keeping sweets in the home was significantly associated with children\u27s consumption of various sweets. For every increase in keeping sweets at home, the odds of children consuming: • Chocolate and other candy increased by 67% (p \u3c 0.01) • Muffins/donuts increased by 40% (p \u3c 0.05) • Cookies, cakes, pies, and other desserts increased by 49% (p \u3c 0.01)https://oasis.library.unlv.edu/durep_lightning/1047/thumbnail.jp

Issues:
Chicano youth and student movement was determined to find a new identity and radical forms of political power that were different from past generations (Munoz Jr., 75)
Chicano students were major contributors to the Chicano movement • The Walkouts were a foundation point for other educational movements in the Chicano communityhttps://oasis.library.unlv.edu/durep_posters/1253/thumbnail.jp
