Learning Style Diversity in Post –Secondary Distance Education

During the fall semester of 2005, 153 university graduate students’ preferred learning styles were measured with the Kolb Learning Style Inventory, online version 3.1. The primary findings of the study indicated all of the learning styles and processes described by Kolb were represented in the distance learning population and suggested distance and residential learners uniquely engage the learning process. Biblical references were discussed with respect to the uniqueness displayed by study participants

Under the Portcullis and Inside the Golden Castle: American Pipe & Construction Co. v. Utah

This Comment discusses to what extent the commencement of a class suit tolls the statute of limitations for the benefit of unnamed or absent members of the class who would have been barred by the statute of limitations from instituting their own individual suits. American Pipe & Construction Co. v. Utah is a recent United States Supreme Court decision that recites and establishes a confluent rationale for tolling the statute of limitations, under purportedly limited and narrow circumstances, for the benefit of all asserted members of the class upon the commencement of the class suit

A Computational and Experimental Investigation of a Three-Dimensional Hypersonic Scramjet Inlet Flow Field

A combined computational and experimental parametric study of the internal aerodynamics of a generic three dimensional sidewall compression scramjet inlet configuration was performed. The study was designed to demonstrate the utility of computational fluid dynamics as a design tool in hypersonic inlet flow fields, to provide a detailed account of the nature and structure of the internal flow interactions, and to provide a comprehensive surface property and flow field database to determine the effects of contraction ratio, cowl position, and Reynolds number on the performance of a hypersonic scramjet inlet configuration

Electronic Still Camera

A handheld, programmable, digital camera is disclosed that supports a variety of sensors and has program control over the system components to provide versatility. The camera uses a high performance design which produces near film quality images from an electronic system. The optical system of the camera incorporates a conventional camera body that was slightly modified, thus permitting the use of conventional camera accessories, such as telephoto lenses, wide-angle lenses, auto-focusing circuitry, auto-exposure circuitry, flash units, and the like. An image sensor, such as a charge coupled device ('CCD') collects the photons that pass through the camera aperture when the shutter is opened, and produces an analog electrical signal indicative of the image. The analog image signal is read out of the CCD and is processed by preamplifier circuitry, a correlated double sampler, and a sample and hold circuit before it is converted to a digital signal. The analog-to-digital converter has an accuracy of eight bits to insure accuracy during the conversion. Two types of data ports are included for two different data transfer needs. One data port comprises a general purpose industrial standard port and the other a high speed/high performance application specific port. The system uses removable hard disks as its permanent storage media. The hard disk receives the digital image signal from the memory buffer and correlates the image signal with other sensed parameters, such as longitudinal or other information. When the storage capacity of the hard disk has been filled, the disk can be replaced with a new disk

Pregnancy lipidomic profiles and DNA methylation in newborns from the CHAMACOS cohort.

Lipids play a role in many biological functions and the newly emerging field of lipidomics aims to characterize the varying classes of lipid molecules present in biological specimens. Animal models have shown associations between maternal dietary supplementation with fatty acids during pregnancy and epigenetic changes in their offspring, demonstrating a mechanism through which prenatal environment can affect outcomes in children; however, data on maternal lipid metabolite levels during pregnancy and newborn DNA methylation in humans are sparse. In this study, we assessed the relationship of maternal lipid metabolites measured in the blood from pregnant women with newborn DNA methylation profiles in the Center for the Health Assessment of Mothers and Children of Salinas cohort. Targeted metabolomics was performed by selected reaction monitoring liquid chromatography and triple quadrupole mass spectrometry to measure 92 metabolites in plasma samples of pregnant women at ∼26 weeks gestation. DNA methylation was assessed using the Infinium HumanMethylation 450K BeadChip adjusting for cord blood cell composition. We uncovered numerous false discovery rate significant associations between maternal metabolite levels, particularly phospholipid and lysolipid metabolites, and newborn methylation. The majority of the observed relationships were negative, suggesting that higher lipid metabolites during pregnancy are associated with lower methylation levels at genes related to fetal development. These results further elucidate the complex relationship between early life exposures, maternal lipid metabolites, and infant epigenetic status

The genome sequence of the Centre-barred Sallow, Atethmia centrago (Haworth, 1809)

We present a genome assembly from an individual male Atethmia centrago (the Centre-barred Sallow; Arthropoda; Insecta; Lepidoptera; Noctuidae). The genome sequence is 926.6 megabases in span. Most of the assembly is scaffolded into 31 chromosomal pseudomolecules, including the Z sex chromosome. The mitochondrial genome has also been assembled and is 15.57 kilobases in length. Gene annotation of this assembly on Ensembl identified 21,345 protein coding genes

Gebser\u27s Integral Consciousness and Living in the Real World: Facilitating its Emergence Using A Course In Miracles

This paper discusses certain parallels between the work of Jean Gebser, the European philosopher and student of consciousness, and A Course in Miracles (ACIM), a contemporary spiritual system. More specifically, it 1) establishes parallels between Gebser’s conception of the ego, especially its basis in anger, and the ego according to ACIM, and 2) shows how a forgiveness exercise may lead to a time-free present, called in ACIM, “The Holy Instant.

Sequence and Expression of Amphioxus Alkali Myosin Light Chain (AmphiMLC-alk) Throughout Development: Implications for Vertebrate Myogenesis

AbstractThe lower chordate amphioxus, widely considered the closest living invertebrate relative of the vertebrates, is a key organism for understanding the relationship between gene duplications and evolution of the complex vertebrate body plan. In tetrapod vertebrates, the alkali myosin light chain genes (MLC-alk), which code for proteins associated with the globular head of the myosin heavy chain, constitute a large family with stage-, tissue-, and fiber-type-specific expression of different isoforms thought to have arisen by duplication of a single ancestral gene. In protostome invertebrates, e.g., arthropods, molluscs, and nematodes, only one MLC-alk gene has been found, but the number of such genes in deuterostome invertebrates and lower vertebrates is unknown. The present report, describing the sequence and expression throughout development of the amphioxus gene for alkali myosin light chain (AmphiMLC-alk), thus fills a major gap in understanding the relation between gene duplication and increasing diversity of muscle-cell types. A full-length clone (1 kb) of AmphiMLC-alk was isolated from a larval amphioxus cDNA library. It coded for a 149-amino-acid protein most closely related to the vertebrate embryonic form of MLC-alk. Southern blot analysis revealed only one copy of AmphiMLC-alk and suggested that it is the only MLC-alk gene in amphioxus. Northern blot analysis indicated that this gene produces only one transcript, which is expressed at all stages of development and in adults. In situ hybridizations showed expression initially in the myotomes of somites 2-5 of neurula embryos and soon thereafter in the myotomes of somite 1 and of newly forming somites progressively added posteriorly. Myotomal expression continues throughout larval development and into the adult stage as the myotomal cells differentiate into striated, mononucleate muscle cells—unlike vertebrate striated muscle cells, those of amphioxus never become multinucleate. In late larvae and adults myotomal expression of AmphiMLC-alk is localized along the medial edge of the myotome and at the ends of the cells. This is the first demonstration of intracellular localization of MLC transcripts in muscle cells of any animal. Expression of AmphiMLC-alk was also detected in smooth muscles as well as in striated muscles not derived from the myotome. These expression data are consistent with the Southern blot analysis in suggesting that there is only one MLC-alk gene in amphioxus. Thus, duplication of an ancestral vertebrate MLC-alk gene probably occurred after the vertebrate and amphioxus lineages split. We conclude that development of a segmented axial musculature preceded the evolution of multiple MLC-alk isoforms, which evidently arose about the time of multinucleation. Since myogenesis in amphioxus is similar to but far simpler than myogenesis in vertebrates at both the structural and gene levels, an understanding of myogenesis in amphioxus can give insights into both the evolutionary history and the detailed mechanisms of vertebrate myogenesis
