Kent State University is a public research university located in Kent, Ohio, United States. The university has eight campuses around the Northeast Ohio region with the main campus in Kent being the largest. Other campuses are located in Ashtabula, Burton, East Liverpool, Jackson Township, New Philadelphia, Salem, and Warren, Ohio.As of September 2014, Kent State is one of the largest universities in Ohio with an enrollment of 41,213 students in the eight-campus system and 29,477 students at the main campus in Kent. It is ranked by the Carnegie Foundation as one of the top 77 public research universities in the US and one of the top 76 in community engagement. In 2010, Kent State was ranked as one of the top 200 universities in the world by Times Higher Education. Kent State offers over 300 degree programs, among them 250 baccalaureate, 40 associate's, 50 master's, and 23 doctoral programs of study, which include such notable programs as nursing, business, history, library science, aeronautics, journalism, fashion design and the Liquid Crystal Institute.The university was established in 1910 as the Kent State Normal School as a teacher-training school. The first classes were held in 1912 at various locations and in temporary buildings in Kent. Since then, the university has grown to include many additional baccalaureate and graduate programs of study in the arts and science, research opportunities, as well as over 1,000 acres and 119 buildings on the Kent campus. During the late 1960s and early 1970s, the university was known internationally for its student activism in opposition to US involvement in the Vietnam War, due mainly to the events of May 4, 1970.

Graphene, a single layer of graphite, possesses a unique two-dimensional structure, high conductivity, superior electron mobility and extremely high specific surface area, and can be produced on a large scale at low cost. Thus, it has been regarded as an important component for making various functional composite materials. Especially, graphene-based semiconductor photocatalysts have attracted extensive attention because of their usefulness in environmental and energy applications. This critical review summarizes the recent progress in the design and fabrication of graphene-based semiconductor photocatalysts via various strategies including in situ growth, solution mixing, hydrothermal and/or solvothermal methods. Furthermore, the photocatalytic properties of the resulting graphene-based composite systems are also discussed in relation to the environmental and energy applications such as photocatalytic degradation of pollutants, photocatalytic hydrogen generation and photocatalytic disinfection. This critical review ends with a summary and some perspectives on the challenges and new directions in this emerging area of research (158 references). © 2012 The Royal Society of Chemistry.

Schizophrenia Bulletin | Year: 2012
Speech of people with schizophrenia is often difficult to follow. There is evidence that neuropsychological deficits associated with schizophrenia explain some of the variance in speech disorder, but its nature and causes overall are not well understood. This study rated speech samples from 60 schizophrenic outpatients for thought disorder, conceptual disorganization, linguistic structural breakdown, and communication failure. A battery of neuropsychological tests potentially relevant to coherent speech production was administered, and associations between these variables and the speech measures were assessed. Consistent with previous research, the measure of functional effect, communication failure, was more highly associated with neuropsychological test performance than were the measures of putative cause: thought disorder, conceptual disorganization, or linguistic structural breakdown. Performance on tests of attention, immediate memory, working memory, organizational sequencing, and conceptual sequencing all were significantly related to the frequency of communication failures in the speech. In hierarchical regression, attention, working memory, and conceptual sequencing each contributed significantly and together explained 29% of the variance. Some other potential contributors to test in future research include auditory attention, internal source memory, emotional disturbances, and social cognitive deficits. © The Author 2011.

The current rapid industrial development causes the serious energy and environmental crises. Photocatalyts provide a potential strategy to solve these problems because these materials not only can directly convert solar energy into usable or storable energy resources but also can decompose organic pollutants under solar-light irradiation. However, the aforementioned applications require photocatalysts with a wide absorption range, long-term stability, high charge-separation efficiency and strong redox ability. Unfortunately, it is often difficult for a single-component photocatalyst to simultaneously fulfill all these requirements. The artificial heterogeneous Z-scheme photocatalytic systems, mimicking the natural photosynthesis process, overcome the drawbacks of single-component photocatalysts and satisfy those aforementioned requirements. Such multi-task systems have been extensively investigated in the past decade. Especially, the all-solid-state Z-scheme photocatalytic systems without redox pair have been widely used in the water splitting, solar cells, degradation of pollutants and CO2 conversion, which have a huge potential to solve the current energy and environmental crises facing the modern industrial development. Thus, this review gives a concise overview of the all-solid-state Z-scheme photocatalytic systems, including their composition, construction, optimization and applications. © 2014 WILEY-VCH Verlag GmbH & Co.

Despite the large and complex conformational space available to an unfolded protein, many small globular proteins fold with simple two-state cooperative kinetics. Understanding what determines folding rates beyond simple rules summarizing kinetic trends has proved to be more elusive than predicting folding mechanism. Topology-based models with smooth energy landscapes give reasonable predictions of the structure of the transition state ensemble, but do not have the kinetic or thermodynamic cooperativity exhibited by two-state proteins. This review outlines some recent efforts to understand what determines the cooperativity and the diversity of folding rates of two-state folding proteins. © 2009 Elsevier Ltd. All rights reserved.

The Beam Energy Scan (BES) program is being pursued at RHIC to study the QCD phase diagram, and search for the possible QCD phase boundary and possible QCD critical point. The data for Phase-I of the BES program have been collected for Au+Au collisions at center-of-mass energies (sNN)of7.7,11.5,19.6,27,and39GeV. These collision energies allowed the STAR experiment to cover a wide range of baryon chemical potential μB(100-400 MeV) in the QCD phase diagram. We report on several interesting results from the BES Phase-I covering the high net-baryon density region. These results shed light on particle production mechanism and freeze-out conditions, first-order phase transition and "turn-off" of QGP signatures, and existence of a critical point in the phase diagram. Finally, we give an outlook for the future BES Phase-II program and a possible fixed target program at STAR. © 2013 Elsevier B.V.
