Southeastern University is a private Christian liberal arts university located in Lakeland, Florida, USA. It was established in 1935 in New Brockton, Alabama as a Bible college, relocated to Lakeland in 1946, and became a liberal arts college in 1970. The school has four colleges and is the largest Assemblies of God educational institution in the United States. The university offers 45 bachelor's degrees and ten master's degrees. Wikipedia.

The Waiapu River sedimentary system, New Zealand, provides a prototype for investigating the relative importance of wave- versus current-supported gravity flows on continental shelf deposition. A two-dimensional model was used to represent gravity-driven sediment transport and deposition on the Waiapu shelf over an annual cycle of storm events and associated Waiapu River floods. Model inputs of waves and wind-driven currents were derived from WAVEWATCH III hindcasts and constrained by benthic tripod data. The 12-month model run included a low-energy period (September 2003 to May 2004) with weak waves and currents and low river discharge, and a high-energy period (May to August 2004) with stronger waves and wind-driven currents and more frequent river floods. Model results suggested that during the low-energy period, riverine sediment was trapped between the 20- and 80-m isobaths. During the high-energy period, sediment was deposited obliquely across the shelf between the 60- and 120-m isobaths. The predicted deposit locations for the low- and high-energy periods, respectively, were consistent with short- and long-term observed accumulation patterns based on 7Be and 210Pb activity [Kniskern, T.A., Kuehl, S.A., Harris, C.K., Carter, L., 2010. Sediment accumulation patterns and fine-scale strata formation on the Waiapu River shelf, New Zealand. Marine Geology 270, 188-201]. Gravity flows were mainly wave-supported landward of the 60-m isobath, but became increasingly current-supported as wave orbital velocity attenuated in deeper water. Both analytical theory and numerical results indicated that wave-supported gravity currents were sensitive to local water depth and favored deposition parallel to isobaths as depth increased. In contrast, current-supported gravity currents were more sensitive to spatial variations in seabed slope, with seaward decreases in slope and along-shelf embayment of bathymetry favoring transport convergence and deposition. We conclude that the longer term (∼100yr) shelf-oblique mud deposit on the Waiapu shelf mainly reflects current-supported gravity flows responding to local variations in seabed slope and curvature of isobaths. © 2010 Elsevier B.V.

This paper lists several methods for cable force measurement in practice and points out that the frequency method is still the most practical and convenient method of cable force measurement in actual engineering, and then evaluates and analyzes the domestic pre-existing practical formulas to calculate cable force by frequency method. Based on the vibration equation of tensile beam, the model of practical formula to calculate cable force of vertical cable with uniform properties is created, which can be used for any constraint conditions, and the proportion variable of practical formula is expressed as a function of the tension-to-bending rigidity ratio (TBR); Using the finite element method, massive data about the proportion variable are obtained for cables with the same TBR but different cable properties (tension, length and bending rigidity), which not only verifies the uniqueness of the proportion variable to TBR but also proves the rationality and validity of taking TBR as the unique independent variable of the proportion variable; Through numerical calculation, the proportion variable is piecewisely fitted to an inverse proportion function of the TBR, and at last according to the established practical formulas, the affections of constraint conditions and bending rigidity to cable force are analyzed, which gradually decreases and can be neglected along with the increase of TBR. Both of the comparative results of domestic pre-existing practical formulas and applications in actual engineering indicate: the practical formulas created according to the cable force calculated at fundamental frequency can make a correct calculation and the calculation precision can satisfy the requirement of actual engineering when TBR is more than one.

This article first reviews the proximity discovery techniques used in most device-to-device communication systems. The associated issues when applied to a cellular network and the potential solutions are then addressed. We propose a unified discovery design for full, partial, and off-network coverage scenarios. We discuss the advantages and disadvantages of packet and signature-based discovery schemes. We present a signature-based discovery design as a conceptual example for cellular applications. Through this example, we demonstrate that a cellular network can benefit from the information provided by the device discovery that a traditional cellular system lacks so that resources, interference, and connection selection can be more efficiently managed under a unified cellular network centric architecture. © 1979-2012 IEEE.

Ribonuclease P (RNase P) catalyzes the metal-dependent 5′ end maturation of precursor tRNAs (pre-tRNAs). In Bacteria, RNase P is composed of a catalytic RNA (PRNA) and a protein subunit (P protein) necessary for function in vivo. The P protein enhances pre-tRNA affinity, selectivity, and cleavage efficiency, as well as modulates the cation requirement for RNase P function. Bacterial P proteins share little sequence conservation although the protein structures are homologous. Here we combine site-directed mutagenesis, affinity measurements, and single turnover kinetics to demonstrate that two residues (R60 and R62) in the most highly conserved region of the P protein, the RNR motif (R60-R68 in Bacillus subtilis), stabilize PRNA complexes with both P protein (PRNA•P protein) and pre-tRNA (PRNA•P protein•pre-tRNA). Additionally, these data indicate that the RNR motif enhances a metal-stabilized conformational change in RNase P that accompanies substrate binding and is essential for efficient catalysis. Stabilization of this conformational change contributes to both the decreased metal requirement and the enhanced substrate recognition of the RNase P holoenzyme, illuminating the role of the most highly conserved region of P protein in the RNase P reaction pathway.

The Bible says all members of "the Body" serve important functions; however, persons with disabilities are noticeably absent from many congregations. This review of literature presents comprehensive research related to existing thoughts on theology and disability studies. Persons with disabilities and their families often struggle for acceptance and inclusion; pastors and congregations with limited experience, resources, and training struggle to understand how to help. Recommendations are made for further research regarding education of future clergy so they will be prepared to welcome people with disabilities as integral members of their congregations. © 2012 Copyright Taylor and Francis Group, LLC.
