Now, new research by Florida State University Professor Thomas Albrecht-Schmitt shows that plutonium doesn't exactly work the way scientists thought it did. The findings will contribute to his team's efforts to develop technologies to clean up nuclear waste. The work was published today in Nature Chemistry. Albrecht-Schmitt and a team of researchers have been studying plutonium -- Pu on the Periodic Table of Elements -- for almost two decades to understand how it behaves chemically, and how it differs from lighter elements like iron or nickel. To Albrecht-Schmitt's surprise, a plutonium-organic hybrid compound that his team assembled in the lab behaved much like compounds made with lighter elements. "What makes this discovery so interesting is that the material -- rather than being really complicated and really exotic -- is really, really simple," Albrecht-Schmitt said. "Your imagination goes wild, and you think 'Wow, I could make that class of compound with many other types of heavy elements.' I could use other heavy elements like uranium or maybe even berkelium." The team observed that electrons were shuttling back and forth between two different plutonium ions. The movement of electrons between two positive ions is an action that typically happens between ions of lighter elements like iron, which is why lighter elements are often used in biology to accomplish chemical reactions. Albrecht-Schmitt said his team immediately realized there was something unique about the compound they had engineered in the lab simply because of its color. "Plutonium makes wild, vibrant colors," Albrecht-Schmitt said. "It can be purple, it can be these beautiful pinks. It can be this super dark black-blue. This compound was brown, like a beautiful brown chocolate bar. When we saw that color, we knew something was electronically unusual about it." Albrecht-Schmitt's work is part of his lab's overall mission to better understand the heavier elements at the very bottom of the periodic table. Last year, he received $10 million from the Department of Energy to form a new Energy Frontier Research Center that will focus on accelerating scientific efforts to clean up nuclear waste. "In order to develop materials that say trap plutonium, you first have to understand at the most basic level, the electronic properties of plutonium," Albrecht-Schmitt said. "So that means making very simple compounds, characterizing them in exquisite detail and understanding both experimentally and theoretically all of the properties you're observing." Albrecht-Schmitt and his research team have conducted similar work on the elements californium and berkelium. Other authors on the paper are FSU graduate students Samantha Cary, Shane Galley, Matthew Marsh, Justin Cross and Jared Stritzinger; FSU research professor David Hobart; National High Magnetic Field Laboratory researcher Ryan Baumbach; Bloomsburg University Assistant Professor of Chemistry Matthew Polinski; and Laurent Maron of the Institut National des Sciences Appliquées in Toulouse, France.

Adding higher frequencies to the American Academy of Pediatrics hearing test protocol helps detect adolescent hearing loss, according to a team of pediatricians and audiologists. "If we can detect hearing loss when it's mild, we can modify behavior," said Deepa Sekhar, associate professor of pediatrics, Penn State College of Medicine. "You can't reverse hearing loss but you can stop the exposure (to hazardous noise) and prevent continued damage." For example, hearing gunshots at close range when out hunting, attending loud concerts or football games, or mowing the lawn with your ear buds cranked up to full volume, can result in hearing loss. Exposure to hazardous noise isn't the only culprit; genetics plays a significant role, varying the effect noise has on a person's hearing. "Young adults can be identified as having reading, emotional or socialization problems and the cause of these problems is actually hearing loss," said Thomas Zalewski, professor of audiology, Bloomsburg University. Sekhar and collaborators worked with the Penn State College of Nursing to conduct the study at Lebanon High School with 134 juniors. Nurses were trained to perform hearing tests with frequencies up to 8,000 Hertz. The highest frequency in the American Academy of Pediatrics hearing test is currently 4,000 Hertz. After two rounds of tests with the new protocol, the study was also repeated in a sound-treated booth, considered the gold standard for performing the test, to confirm the results. State-licensed audiologists analyzed results and two measures -- sensitivity and specificity -- were used to compare the new protocol to the standard protocol in the researchers' paper published in the Journal of Adolescent Health. p>Sensitivity measures how good the test is at identifying if you have hearing loss. Adding the higher frequencies to the standard protocol improved the sensitivity from 58.1 percent to 79.1 percent. Specificity measures how good the test is at identifying if you do not have hearing loss. With two rounds of testing, the specificity decreased slightly from 91.2 percent to 81.3 percent. This decrease was expected, as increasing the sensitivity of a test results in a decrease in specificity. "Hearing loss happens gradually, in a similar way to vision loss," said Zalewski. "People don't realize there are different degrees of hearing loss. It's an invisible disability as there is no overt symptom of a person struggling." Additional collaborators included Jessica Beiler, research project manager in the pediatric clinical research office; Beth Czarnecki, audiologist in the department of audiology; Ian Paul, professor of pediatrics and public health sciences; all at Penn State; and Ashley Barr, audiologist in the department of audiology, now at Cochlear Americas Ltd. The Lebanon School District and Penn State College of Nursing collaborated on this research. The Children's Miracle Network provided funding.

The Hapke (Hapke, B. . J. Geophys. Res. 86, 3039-3054) photometric model and its modifications are widely used to characterize telescopic, spacecraft, and laboratory observations of the bidirectional reflectance of particulate surfaces. Following work and methods laid out in a companion paper (Helfenstein, P., Shepard, M.K. . Icarus, in press), we deconstruct the Hapke model and, separating all empirical and ad hoc parameters (opposition surge, particle phase function, surface roughness), combine them into a single parameter called the surface phase function, F(α). We illustrate how to extract this function from scattering data sets acquired with the Bloomsburg University Goniometer (BUG). We show how this method can be used to rapidly and accurately characterize bidirectional reflectance data sets from laboratory and spacecraft measurements, often giving better fits to the data. We examine samples with strong color contrasts in different wavelengths. This allows us to examine the exact same surface, changing only the albedo to investigate how the amplitude and the detailed shape of the surface phase function might systematically depend on wavelength and albedo. We also examine the changes in scattering behavior that result when samples are compacted and find the surface phase function and single scattering albedo to be significantly changed. We suggest that these observations support the hypothesis that much of the scattering behavior attributed to the single particle phase function is instead cause by the surface micro-structure. © 2011 Elsevier Inc.

In conjunction with a companion paper (Shepard, M.K., Helfenstein, P. . Icarus, submitted for publication), we derive, test, and apply a detailed approach for visualizing the phase angle dependence of light scattering in particulate soils from both whole-disk and disk-resolved observations. To reduce the number of model parameters and provide stronger constraints on model fits, we combine Hapke's (Hapke, B. . Icarus 195, 918-926) recent correction for effects of porosity with his (Hapke, B. . Icarus 67, 264-280) model of the shadow hiding opposition effect. We further develop our method as a tool for least-squares fitting of Hapke's model to photometric data. Finally, we present an improved method for estimating uncertainties in retrieved values of Hapke model parameters. We perform a preliminary test of the model on spectrogoniometric measurements from three selected laboratory samples from Shepard and Helfenstein (Shepard, M.K., Helfenstein, P. . J. Geophys. Res. 112 (E03001), 17). Our preliminary suite of test samples is too small and selective to permit the drawing of general conclusions. However, our results suggest that Hapke's porosity correction improves the fidelity of fits to samples composed of low- and moderate-albedo particles and may allow for more reliable retrieval of porosity estimates in these materials. However, we find preliminary evidence that in high-albedo surfaces, the effects of porosity may be difficult to detect. © 2011 Elsevier Inc.

In this research we explore aspects of learning, social interaction and community across online learning, also known as distance learning, in higher education. We measure the impact of online social networking (OSN) software versus traditional learning management system (LMS) software. Guided by a theoretical model for how individuals learn and interact within online communities, we measure student perceptions of learning, social interaction and course community before and after our interventions. Survey instruments measure perceived learning, social interaction and community, which we further explore using social network analysis (SNA). Survey results identified that students experienced higher levels of perceived social interaction and course community and, overall, had higher levels of satisfaction with OSN software than those using LMS software. Along this line, SNA results corroborated that OSN software yielded a higher number of interactions, providing a more engaging learning experience. © 2014 Elsevier Ltd. All rights reserved.

A partial difference set with parameters (v,v-1/2,v-5/4,v-1/4) is said to be of Paley type. In this paper, we give a recursive theorem that for all odd n>1 constructs Paley partial difference sets in certain groups of order n4 and 9n4. We are also able to construct Paley-Hadamard difference sets of the Stanton-Sprott family in groups of order n4(n4±2) when n4±2 is a prime power and 9n4(9n4±2) when 9n4±2 is a prime power. Many of these are new parameters for such difference sets, and also give new Hadamard designs and matrices. © 2010 Elsevier Inc.

Reportedly, muscle fatigue in older individuals is greater, less than, or similar to young individuals, potentially because of differences in muscle groups studied, type of contraction, continuous vs. intermittent contractions, exercise duration, duty cycle, and contraction speed. During a single set of isokinetic mode knee extensions, muscle fatigue is similar between older and younger individuals. However, repeated sets may favor the more oxidative nature of muscle from older adults and may be necessary to reveal age-associated enhanced fatigue resistance. The purpose of this investigation was to compare muscular fatigue induced by repeated sets of intermittent isokinetic mode knee extensions in older and younger males. Nineteen older (mean ± SD) (66 ± 6 yr) and 16 younger (21 ± 2 yr) men completed 5 sets of 30 isokinetic mode knee extensions at 180 degrees/second. In the analysis of absolute fatigue, both groups significantly decreased torque production during each set, with young men having significantly higher torque production during all 5 sets. Relative fatigue was significantly greater in young participants during sets 2 through 5 (old vs. young: set 2: 17.1 vs. 26.6%; set 3: 25.5 vs. 39.7%; set 4: 28.1 vs. 45.1%; set 5: 29.3 vs. 46.4%; overall relative fatigue: old 22.2%; young 38.1%). These data indicate enhanced fatigue resistance in older men, which was revealed using repeated sets of intermittent contractions. Resistance to muscle fatigue is only one component of healthy aging muscle, and perhaps exercise interventions targeted toward prevention of falls in the elderly should focus on improved muscle power rather than fatigability/ sustainability of contractions. © 2010 National Strength and Conditioning Association.

The ingestion of the dietary supplement creatine (about 20 g/day for 5 days or about 2 g/day for 30 days) results in increased skeletal muscle creatine and phosphocreatine. Subsequently, the performance of high-intensity exercise tasks, which rely heavily on the creatine-phosphocreatine energy system, is enhanced. The well documented benefits of creatine supplementation in young adults, including increased lean body mass, increased strength, and enhanced fatigue resistance are particularly important to older adults. With aging and reduced physical activity, there are decreases in muscle creatine, muscle mass, bone density, and strength. However, there is evidence that creatine ingestion may reverse these changes, and subsequently improve activities of daily living. Several groups have demonstrated that in older adults, short-term high-dose creatine supplementation, independent of exercise training, increases body mass, enhances fatigue resistance, increases muscle strength, and improves the performance of activities of daily living. Similarly, in older adults, concurrent creatine supplementation and resistance training increase lean body mass, enhance fatigue resistance, increase muscle strength, and improve performance of activities of daily living to a greater extent than resistance training alone. Additionally, creatine supplementation plus resistance training results in a greater increase in bone mineral density than resistance training alone. Higher brain creatine is associated with improved neuropsychological performance, and recently, creatine supplementation has been shown to increase brain creatine and phosphocreatine. Subsequent studies have demonstrated that cognitive processing, that is either experimentally (following sleep deprivation) or naturally (due to aging) impaired, can be improved with creatine supplementation. Creatine is an inexpensive and safe dietary supplement that has both peripheral and central effects. The benefits afforded to older adults through creatine ingestion are substantial, can improve quality of life, and ultimately may reduce the disease burden associated with sarcopenia and cognitive dysfunction.

This research will contribute to understanding how landscapes in low topography settings respond to changes in base level (i.e. sea level). These processes are central to interpreting spatial and temporal variation in sediment storage and erosion and have implications for understanding soil loss, pollutant sequestration in soils and floodplains, and flood attenuation over long timescales. The results will also facilitate reconstructions of the changes in the Earths surface in the mid-continent of North America which can provide baseline information from pre-European human landscapes with which to contextualize modern human impacts and thus guide restoration and management.
Through the use of geochronology, field observation, topographic analysis, and GIS we will investigate unresolved problems in geomorphology regarding the impact of variations in lithology on fluvial processes, specifically how lithology impacts bedrock valley and unpaired terrace formation. This project seeks to bring together understanding of processes at variable scales to determine the drivers of river incision in a mid-continent setting south of the glacial limit and to determine whether incision of the Buffalo National River valley has been driven by climate change, base level fall, local processes operating at the scale of the meander, or a combination thereof. The outcomes of this work will improve reconstructions of past landscapes including changes in the hydrologic cycle south of the glacial limit in North America, how bedrock rivers change over time, and how the sedimentary record is created and preserved in caves and alluvial terraces.
