An Investigation into the Parameters Affecting Vehicle Migration During the Redistribution of Aqueous Coatings

The purpose of this study was to determine what effect shear has upon the vehicle migration in aqueous coatings. The roll inclined-plane apparatus was utilized to generate various ranges of shear rate. An immobilization factor was then calculated for these different rates of shear indicating the degree of vehicle penetration. The particle size of the binder and the particle size of the pigment were varied to determine their effect on the penetration into the base substrate. It was concluded that high shear rates pack the particles, either binder or pigment, into the pores of the base substrate. This phenomenon prevents the migration of the liquid phase

Introducing IPv6 Tokenised Interface Identifiers into the Linux Kernel

IPv6 Stateless Address Autoconfiguration (SLAAC) enables network administrators to deploy devices in a network and have those devices automatically generate global addresses without any administrative intervention, and without the need for any stateful configuration service such as DHCPv6. However, certain services --- such as HTTP, SMTP and IMAP --- may better benefit from having "well known" identifiers that do not depend on the physical hardware address of the server's network interface card. Tokenised addresses offer facility for administrators to specify the bottom 64 bits of an IPv6 address for a node whilst allowing the top 64 bits (the network prefix) to be automatically configured from router advertisements. This report documents the approach taken and experience gained from introducing tokenised interface identifiers into the Linux 2.6.11 kernel, as shipped with Redhat Fedora Core 4. This proof of concept work demonstrates the relative ease of introducing this useful utility for network node deployment, and further motivates wider deployment of the semi-automatic configuration approach

Investigating scientific literacy: Scientist’s habits of mind as evidenced by their rationale of science and religious beliefs

Science and technology have been incredibly success¬ful in purely technical terms. For instance, international air travel, space flight, and curing of hitherto untreatable medical illnesses all are now routine events. One feature of the incredible (and seemingly ever increasing) advance of science and technology is a sense of unease amongst the general population of science’s potential to change our lives, in sometimes unpredictable and alarming ways. Public understanding of science, or scientific literacy, is of increasing concern worldwide according to much recent literature

Woodland and Caddo Period Sites at Toledo Bend Reservoir, Northwest Louisiana and East Texas

Toledo Bend Reservoir is one of the largest artificial lakes in the United States and the largest reservoir in the South. The lake is approximately 65 miles long and contains over 1200 miles of shoreline in both Louisiana and Texas. Construction began in 1964 with completion of the power plant, with the subsequent filling of the lake in 1969. Archaeological investigations at Toledo Bend Reservoir on the Sabine River and tributaries in both Louisiana and Texas took place primarily took during the 1960s, with survey and excavations, sometimes of a very limited nature by the University of Texas (UT) and Southern Methodist University (SMU). Girard has continued archaeological investigations along the Louisiana side of the reservoir, however, focusing particularly on work at the James Pace site. In this article we review the nature of the material culture assemblage of the Woodland and Caddo sites at Toledo Bend Reservoir based on the collections at the Texas Archeological Research Laboratory at The University of Texas at Austin (TARL). This consists of ceramic and/or lithic artifacts from 76 different sites in Louisiana and Texas. We have also examined ceramic vessels from Woodland and Caddo burial features at several Toledo Bend Reservoir sites. Our purpose in re-examining the TARL collections from the Toledo Bend Reservoir is to better understand and characterize the material culture assemblages (primarily decorated ceramic sherds) from sites that date between ca. 2500 years B.P. and the late 17th-early 18th century A.D., particularly in light of questions concerning the cultural affiliation and cultural taxonomic relationships of the ancestral Caddo sites in this part of East Texas and western Louisiana

Caddo Ceramic Vessels from the Womack Site (41LR1), Lamar County, Texas

The Womack site (41LR1) is an ancestral Caddo settlement situated on an alluvial terrace in a horseshoe bend of the Red River in north central Lamar County in East Texas. Harris completed the analysis and study of their 1938-mid-1960s investigations at the site, but the findings from the earlier archaeological investigations conducted at the site by the University of Texas (UT) in 1931 have only been recently published

Analysis of the 19th Century Historic Archaeological Material Culture Remains from the Browning Site in Smith County, Texas

The Browning site (41SM195A) is located on a 3800 m2 alluvial terrace that overlooks the Auburn Creek floodplain in eastern Smith County, Texas. This setting is near the headwaters of a stream system in the Harris Creek drainage; Harris Creek meets the Sabine River ca. 34 km to the north. In the vicinity of the Browning site, the valley, being narrow with steep valley walls, offers few locations suitable for either prehistoric or historic occupations. Soils here arc Entisols; they vary in depth from 30-70 em across the landform, terminating at a sandstone C-horizon. These arc soils that formed mostly under forest vegetation and are dominantly sandy or loamy. The Browning site falls within the Pineywoods vegetation area and represents the western extent of the pine and deciduous forests of the Southeastern U.S. coastal plain. Archaeological investigations at the Browning site have been carried out intermittingly for several years by the junior author. That work has led to the recognition that it is a stratified site with two very distinct occupations, an early to mid-19th century assemblage of historic artifacts primarily in an upper zone (0-20 em bs) overlying a buried (20-50 em bs) Late Woodland period occupation. The historic occupation is in the center of the terrace, covering approximately 500m2• The historic artifacts arc found primarily in the upper sediments, but due probably to pedoturbations, they have been found as deep as 50 em in the underlying prehistoric archaeological deposits. Excavations at the Browning site have consisted of 41 1 x 1 m units (with a total excavated volume of 20.4 m3) and 22 shovel tests. Surface collections were obtained from the site in 1996 and 2002. The 22 shovel tests excavated at the site were conducted first to better ascertain the limits of the site and identify areas of concentrated cultural activity; ST 4, 8-9, 12, and 19 contained 19th century historic artifacts. Once a buried prehistoric occupation zone was identified, units were placed primarily in cardinal directions to better define the occupation zone\u27s boundaries and levels of occupational intensity, and also sample the overlying 19th century component. The I x 1 m units were excavated in arbitrary l 0 em levels and the soil was dry-screened for artifacts through I /4-inch hardware cloth except for a fine screen sample from Unit I that was water-screened through I /32-inch mesh. A level sheet was completed at the end of each level. Profiles were drawn of one wall of each unit or a common wall when several units were joined. The shovel tests followed the same procedures, except they were excavated in arbitrary 20 em levels. One feature had four refined earthenware sherds (as well as two prehistoric artifacts) and 15 small pieces of animal bone. This was a shallow pit with a very dark grayish-brown sandy loam fill (with charcoal flecks) and a rounded bottom that was 63 em in diameter and extended from 22-29 em bs

The Jonas Short Site (41SA101), San Augustine County, Texas

The Jonas Short site (41SA101) is one of a few known and investigated Woodland period mounds in the Trans–Mississippi south (i.e., East Texas, Northwest Louisiana, Southwest Arkansas, and Southeast Oklahoma). In fact, the site is one of only four identified mound sites of possible Woodland period age—and Mossy Grove cultural tradition—in the Neches–Angelina and Sabine river basins in East Texas and Northwest Louisiana: Coral Snake (16SA48), Anthony (16SA7), Jonas Short, and Westerman (41HO15). The Jonas Short site was located on an alluvial terrace of the Angelina River. It was investigated in 1956 by archaeologists from the University of Texas and the River Basin Survey prior to its inundation by the waters of Lake Sam Rayburn
