LRS Route Master

<p>This feature class consists of approximately 198,000 features representing over 70,000 miles of Interstate, Primary, Secondary and Urban roads throughout the State of Virginia. The Linear Referencing System is based on the Virginia Department of Transportation's Source System of Record for road inventory, Roadway Inventory Management System (RIMS).&nbsp;&nbsp;</p><div>&nbsp;</div><div>Geometry and Attribution: The Linear Referencing System (LRS) data contained within this feature class provides dissolved route segmentation (i.e. routes are not segmented when they intersect other routes), thus rendering one table record per route. Multi-part geometry is created where routes are noncontiguous (e.g. a valid physical gap exists because another route is the master). The feature class only depicts master routes, those are routes built in the prime direction and on divided roadways where the non-prime direction is the master. Each road centerline record has a master route record assigned.&nbsp;</div><div>&nbsp;</div><div>Measures: The linear reference is based on Official State Mileage (OSM) as derived from reference points at Roadway Inventory Management System (RIMS) roadway intersections (i.e. nodes/junctions).&nbsp;</div><div>&nbsp;</div><div>Purpose: This linear referenced data layer represents roadways that are maintained by the Virginia Department of Transportation and provides the underlying spatially enabled geometric network to which all "events" (e.g. potholes, pavement type, vehicle accidents, traffic counts, culverts, etc...) can be located. Note: The overlap and non-prime measures are for reference only and have not been fully validated for accuracy or completeness.</div>
Virginia City/County Census Boundaries 2010

<div>This service is Virginia data from the 2011 release of the Census Bureau TIGER/Line Shapefile for national counties or equivalent boundaries (tl_2011_us_county.shp)</div><div><br /></div><div>The TIGER/Line Files are shapefiles and related database files (.dbf) that are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line File is designed to stand alone as an independent data set, or they can be combined to cover the entire nation.</div><div><br /></div><div>The primary legal divisions of most States are termed counties. In Virginia, cities are independent of any county organization and thus constitute primary divisions. These incorporated places are known as independent cities and are treated as equivalent to counties for purposes of data presentation.</div><div><br /></div><div>The 2010 Census boundaries for counties and equivalent entities are as of January 1, 2010, primarily as reported through the Census Bureau's Boundary and Annexation Survey (BAS).</div>
LRS Route Overlap

<p>This feature class consists of approximately 507,000 features representing over 70,000 miles of Interstate, Primary, Secondary and Urban roads throughout the State of Virginia. The Linear Referencing System is based on the Virginia Department of Transportation's Source System of Record for road inventory, Roadway Inventory Management System (RIMS).</p><div><div>Geometry and Attribution: The Linear Referencing System (LRS) data contained within this feature class provides dissolved route segmentation (i.e. routes are not segmented when they intersect other routes), thus rendering one table record per route. In cases where routes are noncontiguous (e.g. a valid physical gap exists), multi-part geometry is created. The feature class also depicts overlapping routes (e.g. Interstate 64 and Interstate 95) as two separate collinear features, one on top of the other. Routes built in the prime and non-prime directions are included. Each road centerline record has a master route record assigned. This feature class is best suited for labeling roadways when overlap reference is needed.</div><div>&nbsp;</div><div>Measures: The linear reference is based on Official State Mileage (OSM) as derived from reference points at Roadway Inventory Management System (RIMS) roadway intersections (i.e. nodes/junctions).&nbsp;Purpose: This linear referenced data layer represents roadways that are maintained by the Virginia Department of Transportation and provides the underlying spatially enabled geometric network to which all "events" (e.g. potholes, pavement type, vehicle accidents, traffic counts, culverts, etc...) can be located.</div></div>
Identification of the source of in vitro toxicity of the particulate from sanding solid-surface composite

This dataset contains results from laboratory tests examining how dust from common solid-surface materials, like Corian® used in countertops, affects lung cells. Sanding these materials during manufacturing or installation creates fine dust containing the material itself (like aluminum trihydrate, ATH) and potentially particles from the sandpaper. There have been concerns about lung diseases, such as pulmonary fibrosis, in workers exposed to this dust. This study aimed to figure out whether the dust from the Corian® itself or tiny particles from the sandpaper (aluminum oxide, ceramic, or silicon carbide) were more responsible for harmful effects on cells. Researchers exposed cultured human lung cells (THP-1 macrophages, which act like immune cells) to fine dust collected after sanding Corian® with the different sandpapers. They also tested the cells separately with the abrasive particles used in the sandpapers and with ATH. Using advanced automated microscopy (high-content imaging), they measured signs of cell stress like cell death (apoptosis and necrosis), changes in cell growth (cell cycle), and damage to the cell's nucleus. The main finding was that the dust from sanding Corian®, as well as ATH alone, caused a specific type of cell death (apoptosis). However, this dust didn't cause significant immediate cell membrane damage or interfere strongly with how the cells divided. In contrast, the abrasive particles alone did cause problems with cell division and the cell cycle, along with some cell death, but their overall pattern of effects was different from the combined Corian® dust. This suggests that the Corian® material itself, likely the ATH component, is a primary driver of the initial apoptotic stress response seen in these lung cells in vitro.
