    A Qualitative Study of College Students with Autism: Resilience and Spirituality

    While research as been conducted on resilience and spirituality among parents of individuals diagnosed with autism spectrum disorder, there is a distinct lack of research examining these variables within the context of the direct experiences of individuals diagnosed with autism. The present study seeks to examine whether individual resiliency and spirituality play a role in the lives of college students with autism, as well as whether these factors contribute to the development of spiritual coping mechanisms. College students with autism may demonstrate how to strengthen their resilience and spirituality, as well as whether spiritual coping mechanisms are common among college students with autism. This qualitative study will collect data from a sample of college-aged individuals diagnosed with autism currently attending Liberty University. Participants will attend individual long-form, semi-structured interviews before completing a resiliency survey, which will be coded for analysis. Interviews are currently ongoing and will be coded for analysis once complete. It is expected that the analysis will identify themes of resiliency and evidence of spiritual coping mechanisms among college students diagnosed with autism. Studying resiliency and spirituality in individuals with autism rather than focusing on the experiences of parents or guardians opens the door to further discussion on the individual experience of autism

    Moderation of high-energy fast neutrons in beryllium from a tokamak fusion reactor and heat transfer to the cooling water system

    A modeling demonstration of the moderation of 14.1 MeV primary neutrons in beryllium emitted from a D-T fusion nuclear reaction. The energy deposited from neutron-beryllium interactions which produces heat in the blanket of a fusion tokamak. A review of literature and data available for neutron-beryllium interactions is provided to support the MC software of a simplified model of the ITER first wall and blanket. Energy deposited in regions of the model using FLUKA are used to calculate a polynomial heat flux profile through the model. One dimensional conductive heat transfer through the model is performed and the cooling capacity of the coolant channels via convective heat transfer is explored

    Estimating the environmental costs of the hydro fuel cycle using life cycle assessment techniques and economic valuation

    A Life Cycle Assessment model, with an integrated impact assessment, is used to estimate average external economic damages from the hydro fuel cycle. Aggregated average damage assessments of the hydro fuel cycle are complementary to marginal and site specific assessments, and are useful for general energy policy planning. For the upstream inventory assessment, detailed material input data from the Morrow Point Dam is used to estimate material inputs at 174 New England, and 4 Quebec, concrete hydroelectric projects. LCNetBase input-output life cycle assessment software, developed by Dr. Gregory Norris at Sylvatica, is used to estimate upstream emissions associated with material inputs and construction activities. Operations-phase emissions assessed include methane (CH4), carbon dioxide (CO2) and methyl mercury (MeHg), which are primarily associated with microbial activity in reservoirs. In the impact assessment, economic valuation is used to estimate the environmental impact associated with emissions from the hydro fuel cycle. Estimates of average externalities are as follows: small NE dams = .0343/kWh,mediumNEdams=.0343/kWh, medium NE dams = .0202/kWh, large NE dams = .0193/kWh,HydroQuebec,LaGrandeComplex=.0193/kWh, Hydro Quebec, La Grande Complex = .0461/kWh. Results indicate that the average external impacts from the hydro fuel cycle are less than, but similar to, the external costs from fossil fuel cycles. However, more detailed assessment of individual projects shows that emissions from the majority of hydro projects are very small as compared to fossil fuel cycles. In contrast, site specific characteristics at a small handful of hydro projects greatly exceed emissions per unit of energy for the coal fuel cycle, and increase the average estimates for small, medium and large New England dams

    Development of multicomponent coupled-cluster theory and its application to nanoclusters and molecular systems

    Many theoretical and computational methods are based upon the Born-Oppenheimer approximation. This approximation greatly simplifies the search for a wave function that describes all electrons and nuclei in a chemical system. This is accomplished by assuming that the motion of nuclei and electrons are vastly different; the motion of the two particle types is decoupled. While the BO approximation is ubiquitous in computational and theoretical studies, it is not always justifiable. There are two main cases where this approximation is not valid. The first is when nuclear and electronic motion cannot be decoupled. Decoupling the motion leads to incorrect observations and conclusions drawn. The second case is when a chemical system has more than one type of particle to be treated without the Born-Oppenheimer approximation. For these types of systems, a different and more general interpretation of the Born-Oppenheimer approximation must be made where multiple particle types can be investigated whose motion is not decoupled from one another. In order to investigate systems that are classified in this more inclusive interpretation, new computational theories and methods are needed. To accomplish this task, the multicomponent coupled-cluster method has been developed. In its present form, this new computational method is capable of treating two types of particles without de- coupling their motion. The fundamental theories and methods for multicomponent coupled-cluster theory are discussed before the derivation and resulting multicomponent coupled-cluster equations are discussed. This method was then used to study excited electronic states in molecular systems and semiconductor quantum dots via the electron-hole representation. It was also used to calculated ground state energy of the positronium hydride system. These projects sparked further interest in the con- sequences of the Born-Oppenheimer approximation’s application to chemical systems and how it compares to a non Born-Oppenheimer treatment

    Ellis reports that his health is improving. He reports to Finley (Presiding Elder of Zanesville District) that he is having difficulty with his colleague assigned to the Granville Circuit. R. Doughty is not visiting delynquent\u27\u27 members. Some of the members believe that Doughty ought not to be traveling a circuit at all, and that he would be better off as a Local Preacher. Ellis tells Finley that he bears no ill will against Doughty. Abstract Number - 851https://digitalcommons.owu.edu/finley-letters/1338/thumbnail.jp

    Using the principle of quasi-continuous filtering in a non-linear fibre, we propose an optical device for the simultaneous regeneration of sevaral channels at 40 Gbit/s. Simulations predict an improvement of the signal quality for four channels by more than 6.8 dB
