Genetic, Biochemical, and Electron Microscopic Analysis of Components Involved in Transcription Coupled mRNA Export
In the eukaryotic cell, the nuclear envelope separates the nucleoplasm from the cytoplasm. The nuclear pore complex (NPC) forms the conduit that regulates the exchange of macromolecules between these compartments. Import and export of protein and RNA through the NPCs are highly regulated and follow …

Comparative analysis of bacterial and fungal communities in two dairy parlors through the use of pyrosequencing, riboprinting, culture techniques, and microscopic analysis
… of this study was to compare three different analysis techniques used to characterize and identify bacteria and fungi. Pyrosequencing, culture techniques, and riboprinting were compared for all of the bacterial samples and pyrosequencing; culture techniques; and microscopic analysis was used …

The AutoScope : an automated point-of-care urinalysis system
… project was to develop an automated, low-cost microscopic urinalysis system that could accurately detect red blood cells (RBCs), white blood cells (WBCs), and other particles in urine. The Autoscope is a proof-of-concept for this end-to-end automated microscopic urinalysis system. A similar …

Evaluation of Tensile Bond Strength of Glass Ionomer Cements for Orthodontic Bonding
… The type bond failure was determined with light microscopic analysis of the debonded bracket bases. The finite element method was used to further evaluate the bracket/adhesive/enamel complex with varying angulation of force application at debonding. The mean tensile bond strength value of 0.82 ± …

Stabilised decellularised vascular grafts in an ovine carotid model
… which the grafts were explanted for macro- and microscopic analysis. Results: In-vitro evaluation: Grafts showed significant levels of bound heparin (14.56 mg/g vs 0.69mg/g in untreated tissue) and demonstrated similar mechanical properties to those of human carotid arteries. Survival: Five out …

Quantitative and consistent tests for interlayer adhesion in laminated glass
… low and high adhesion. Stress and fracture analysis was conducted using the finite element method. The numerical analysis was first validated against simple strength of materials analyses and the measured load deflection response. The numerical analysis then provided the variation of stress …

Arachidonate 15-lipoxygenase and ubiquitin as potential fertility markers in boars
… performed to determine whether using high power microscopic analysis and two putative biochemical fertility markers, 15-lipoxygenase (15-LOX) and ubiquitin (UBI), could be used to accurately evaluate boar semen quality. In this study, ejaculates (n=116) were collected from 18 Large White boars …

Assessment of Arsenic Mobility Using Sequential Extraction and Microscopic Methods
… In this study, sequential extraction and microscopic methods were used to evaluate arsenic partitioning in different phases in sediments and host rock at the Brinton arsenic mine (BAM) site. Results demonstrate spatial variability of arsenic in sediments, although the partitioning of …

A Study of Commercial Aviation Demand and Revenue Responses to Changes in Ticket and Segment Tax
… tax scenarios through the Transportation Systems Analysis Model (TSAM) and the TSAM Aggregation for the Strategy Simulator (TASS) model. TSAM provides a more microscopic analysis of demand by including spatial representation and mode choice in the model. TASS is a work in progress that aggregates …
