The pyralid genus crambus in Tennessee, with description of the moths, notes on their habits and occurrence, and keys to the adults and their larvae

In the present paper an attempt is made to bring together careful and newly rewritten descriptions of the adult moths of all the species occurring in Tennessee. No previous attempt has been made to describe the genitalia altho Felt many years ago figured some of them. The notes on the habits, distribution and seasonal history of the various species are the result of numerous observations made during the past ten years in the writer\u27s travels over the state. For some of the species there is not previous record of any of the facts of their life histories and for none of them has any record been made of their habits in Tennessee except in a few articles published by the writer

A scaling analysis of ozone photochemistry

International audienceA scaling analysis has been used to capture the integrated behaviour of several photochemical mechanisms for a wide range of precursor concentrations and a variety of environmental conditions. The Buckingham Pi method of dimensional analysis was used to express the relevant variables in terms of dimensionless groups. These grouping show maximum ozone, initial NOx and initial VOC concentrations are made non-dimensional by the average NO2 photolysis rate (jav) and the rate constant for the NO?O3 titration reaction (kNO); temperature by the NO?O3 activation energy (ENO) and Boltzmann constant (k) and total irradiation time by the cumulative jav?t photolysis rate. The analysis shows dimensionless maximum ozone concentration can be described by a product of powers of dimensionless initial NOx concentration, dimensionless temperature, and a similarity curve directly dependent on the ratio of initial VOC to NOx concentration and implicitly dependent on the cumulative NO2 photolysis rate. When Weibull transformed, the similarity relationship shows a scaling break with dimensionless model output clustering onto two straight line segments, parameterized using four variables: two describing the slopes of the line segments and two giving the location of their intersection. A fifth parameter is used to normalize the model output. The scaling analysis, similarity curve and parameterization appear to be independent of the details of the chemical mechanism, hold for a variety of VOC species and mixtures and a wide range of temperatures and actinic fluxes

A scaling analysis of ozone photochemistry: II Investigation of the similarity relationship

International audienceThe similarity relationship for maximum ozone concentration as a function of initial precursor concentrations developed in the first article of this 2-part series exhibits a scale break, most easily seen after a Weibull transformation, which identifies a characteristic scale for ozone photochemistry. In this paper, we investigate the similarity relationship using simple semi-quantitative models and model output. From this investigation, we develop a set of properties characterizing ozone-precursor relationships. We find the scaling break is associated with a change in the temporal variability of ozone production. Finally, we examine a series of smog chamber experiments for evidence of a scaling break. We find the data support a slight break after suitable transformation. It is difficult to tell if the lack of distinct break is due to smog chamber experimental limitations, a bias in the test conditions or if the processes leading to the scaling break are overly enhanced by chemical mechanisms

A scaling analysis of ozone photochemistry: I Model development

International audienceA scaling analysis has been used to capture the integrated behaviour of several photochemical mechanisms for a wide range of precursor concentrations and a variety of environmental conditions. The Buckingham Pi method of dimensional analysis was used to express the relevant variables in terms of dimensionless groups. These grouping show maximum ozone, initial NOx and initial VOC concentrations are made non-dimensional by the average NO2 photolysis rate (jav) and the rate constant for the NO-O3 titration reaction (kNO); temperature by the NO-O3 activation energy (ENO) and Boltzmann constant (k) and total irradiation time by the cumulative jav?t photolysis rate (?3). The analysis shows dimensionless maximum ozone concentration can be described by a product of powers of dimensionless initial NOx concentration, dimensionless temperature, and a similarity curve directly dependent on the ratio of initial VOC to NOx concentration and implicitly dependent on the cumulative NO2 photolysis rate. When Weibull transformed, the similarity relationship shows a scaling break with dimensionless model output clustering onto two straight line segments, parameterized using four variables: two describing the slopes of the line segments and two giving the location of their intersection.

Flux jumps in high-J <inf>c</inf> MgB<inf>2</inf> bulks during pulsed field magnetization

Pulsed field magnetization (PFM) of a high-J_c MgB_2 bulk disk has been investigated at 20 K, in which flux jumps frequently occur for high pulsed fields. Using a numerical simulation of the PFM procedure, we estimated the time dependence of the local magnetic field and temperature during PFM. We analyzed the electromagnetic and thermal instability of the high-J_c MgB_2 bulk to avoid flux jumps using the time dependence of the critical thickness, d_c(t), which shows the upper safety thickness to stabilize the superconductor magnetically, and the minimum propagation zone length, l_m(t), to obtain dynamical stability. The values of d_c(t) and l_m(t) change along the thermally-stabilized direction with increasing temperature below the critical temperature, T_c. However, the flux jump can be qualitatively understood by the local temperature, T(t), which exceeds T_c in the bulk. Finally, possible solutions to avoid flux jumps in high-J_c MgB_2 bulks are discussed.This work was supported by Open Partnership Joint Projects of Japan Society for the Promotion of Science (JSPS) Bilateral Joint Research Projects, and JSPS KAKENHI grant number 23560002 and 15K04646.

The dissemination and implementation of national asthma guidelines in south africa: the use of outcome mapping

Asthma is an important chronic inflammatory disorder with significant morbidity and mortality in South Africa. The development of national asthma guidelines by the South African Thoracic Society and National Asthma Education Programme has been one approach to try and improve the quality of care. The impact of previous guidelines has been limited and therefore it is hoped that the newly revised 2007 guidelines will have a more effective approach to dissemination, implementation and evaluation. Outcome mapping (OM) is one approach to integrated planning, monitoring and evaluation of projects that intend to contribute to change in complex systems. It has a structured, systematic and logical approach that focuses on changes in behaviour, actions or relationships in the people or organizations that the project is working with. OM has three stages - intentional design, outcome/performance monitoring and evaluation - which are described in this article and illustrated with reference to the Asthma Guideline Implementation Project (AGIP). In the intentional design stage the AGIP created a vision and mission statement to guide the project and then identified seven boundary partners. For each boundary partner the AGIP defined the project's outcome challenge and a series of progress markers to monitor achievement of the outcome. Following this the AGIP conceptualized the strategies and organizational practices that will be engaged with to realize the outcomes. In the monitoring stage the AGIP will regularly document and reflect on the progress markers, strategies and organizational practices using pre-determined structured journals. In the evaluation stage there is the opportunity to plan the evaluation of key aspects of the project in more depth. In the AGIP project the team engaged with the development of a doctoral research project to evaluate the process of implementation in private and public primary care settings in the Cape Town metropole. This article describes the methodology of Outcome Mapping and illustrates this in relation to the Asthma Guidelines Implementation Project. The methodology has the potential to be applied in many other development projects and is also congruent with action research. It is hoped that the readers will find this approach useful in their own settings

Love in education: West Australian early childhood pre-service teachers\u27 perspectives on children\u27s right to be loved and its actualisation within their future practice

Children\u27s right to love is a recognised fundamental human need set down within the 1992 United Nations Convention on the Rights of the Child. This recognition stems from an acknowledgement that the Early Years of Development are emotionally driven (Degotardi, S., & Sweller, N. (2012). Mind-mindedness in infant child-care: Associations with early childhood practitioner sensitivity and stimulation. Early Childhood Research Quarterly, 27(2), 253–265. doi:10.1016/j.ecresq.2011.09.002.). Young children respond best to those with whom they experience love and acceptance (Carter, M. A., & Fewster, C. (2013). Diversifying early years’ professional learning: One size no longer fits all. Australasian Journal of Early Childhood, 38(1), 73–⁠80.). As such, love in the classroom is important as an empowering agent of children\u27s well-being and achievement. Children’s need and right to be surrounded by love poses a challenge for many early childhood teachers as they strive to meet the emotional needs of children within a professional care-based relationship (Goldstein, J. (2012). Children’s development, health and well-being. Waterloo, Brussels: Toy Industries of Europe (TIE); Walsh, K., & Brandon, L. (2012). Their children’s first educators: Parents’ views about child sexual abuse prevention education. Journal of Child and Family Studies, 21(5), 734–746. doi:10.1007/s10826-011-9526-4.). This research presents pre-service teachers’ perspectives on love in early childhood education; their definitions, their understanding of its role within the development, and their visions of how it can be actualised within their practice

Duration of disease does not equally influence all aspects of quality of life in Parkinson’s disease

Health related quality of life (HRQoL) is negatively impacted in patients suffering from Parkinsons disease (PD). For the specific components that comprise HRQoL, the relationship between clinical variables, such as disease duration, is not fully characterized. In this cross-sectional study (n=302), self-reported HRQoL on the Parkinsons Disease Questionnaire (PDQ-39) was evaluated as a global construct as well as individual subscale scores. HRQoL was compared in three groups: those within 5years of diagnosis, those within 6-10years of diagnosis, and those greater than 11years since diagnosis. Non-parametric analyses revealed lower HRQoL with increasing disease duration when assessed as a global construct. However, when subscales were evaluated, difficulties with bodily discomfort and cognitive complaints were comparable in individuals in the 1-5years and 6-10year duration groups. Exploratory regression analyses suggested disease duration does explain unique variance in some subscales, even after controlling for Hoehn and Yahr stage and neuropsychiatric features. Our findings show that HRQoL domains in PD patients are affected differentially across the duration of the disease. Clinicians and researchers may need to tailor interventions intended to improve HRQoL at different domains as the disease progresses

A Trapped Field of 17.6 T in Melt-Processed, Bulk Gd-Ba-Cu-O Reinforced with Shrink-Fit Steel

The ability of large grain, REBa$_{2}$Cu$_{3}$O$_{7-\delta}$ [(RE)BCO; RE = rare earth] bulk superconductors to trap magnetic field is determined by their critical current. With high trapped fields, however, bulk samples are subject to a relatively large Lorentz force, and their performance is limited primarily by their tensile strength. Consequently, sample reinforcement is the key to performance improvement in these technologically important materials. In this work, we report a trapped field of 17.6 T, the largest reported to date, in a stack of two, silver-doped GdBCO superconducting bulk samples, each of diameter 25 mm, fabricated by top-seeded melt growth (TSMG) and reinforced with shrink-fit stainless steel. This sample preparation technique has the advantage of being relatively straightforward and inexpensive to implement and offers the prospect of easy access to portable, high magnetic fields without any requirement for a sustaining current source.Comment: Updated submission to reflect licence change to CC-BY.
