Big Bang Nucleosynthesis with Independent Neutrino Distribution Functions

We have performed new Big Bang Nucleosynthesis calculations which employ arbitrarily-specified, time-dependent neutrino and antineutrino distribution functions for each of up to four neutrino flavors. We self-consistently couple these distributions to the thermodynamics, the expansion rate and scale factor-time/temperature relationship, as well as to all relevant weak, electromagnetic, and strong nuclear reaction processes in the early universe. With this approach, we can treat any scenario in which neutrino or antineutrino spectral distortion might arise. These scenarios might include, for example, decaying particles, active-sterile neutrino oscillations, and active-active neutrino oscillations in the presence of significant lepton numbers. Our calculations allow lepton numbers and sterile neutrinos to be constrained with observationally-determined primordial helium and deuterium abundances. We have modified a standard BBN code to perform these calculations and have made it available to the community.Comment: 9 pages, 5 figure

2016 Payton Lectures: Reading John Missionally

Fuller Theological Seminary instituted the Payton Lectures in 1948, providing for a series of divinity lectures by a notable scholar outside the regular faculty. The lectureship is named for Dr. John E. and Mrs. Eliza Payton, parents of the late Mrs. Grace Fuller, wife of seminary founder Charles E. Fuller. El Seminario Teológico de Fuller instituyó las Conferencias Payton en 1948, proveyendo una serie de conferencias en divinidades por una persona erudita de renombre fuera de la facultad regular. Las conferencias llevan el nombre del Dr. John E. y la Sra. Eliza Payton, padres de la fallecida Sra. Grace Fuller, esposa del fundador del seminario Charles E. Fuller. 풀러신학대학원은 1948년 페이튼 강좌를 개설하여 정규 교수진 외에 저명한 학자의 신학 강연을 제공해왔습니다. 강좌의 명칭은 학교 설립자 찰스 풀러 (Charles E. Fuller)의 아내인 그레이스 풀러 (Grace Fuller) 부인의 양친 존 페이튼 (John E. Payton) 박사와 엘리자 페이튼 (Eliza Payton) 부인의 이름을 따라 붙여졌습니다

Does The Hype Exceed The Reality For ERP Applications And Small Manufacturing Companies: A Case Study

This case study describes the implementation of an ERP in a new arena – small manufacturing companies – and explores possible differences compared with successful implementations of ERP’s in larger manufacturing companies. The company that was studied is a small manufacturing company in Maine (less than $10 million in annual sales) that began implementing a small business ERP 12 months ago. Information was collected through interviews and the completion of a questionnaire based on the Stratman-Roth ERP Competence Scales (2002). Results suggest that while this company’s ERP implementation has been more positive than negative, a small company’s limited financial resources and lack of internal experience and expertise in large IT system projects add to the already complex challenges surrounding an ERP implementation

LOCATION OF A MIXALCO PRODUCTION FACILITY WITH RESPECT TO ECONOMIC VIABILITY

Monte-Carlo simulation modeling is used to perform a feasibility study of alternative locations for a MixAlco production facility. Net present value distributions will be ranked within feasible risk aversion boundaries. If MixAlco is a profitable investment, it would have a major impact on the fuel oxygenate and gasoline markets.Resource /Energy Economics and Policy,

Alignments of the Dominant Galaxies in Poor Clusters

We have examined the orientations of brightest cluster galaxies (BCGs) in poor MKW and AWM clusters and find that, like their counterparts in richer Abell clusters, poor cluster BCGs exhibit a strong propensity to be aligned with the principal axes of their host clusters as well as the surrounding distribution of nearby (< 20/h Mpc) Abell clusters. The processes responsible for dominant galaxy alignments are therefore independent of cluster richness. We argue that these alignments most likely arise from anisotropic infall of material into clusters along large-scale filaments.Comment: 8 pages, 5 figure
