Archaeological Survey of the Covel Gardens Landfill Area in San Antonio, Bexar County, Texas

In March 1990, archaeologists from the Center for Archaeological Research, The University of Texas at San Antonio, conducted a surface survey and subsurface testing at a locality proposed for a landfill by Waste Management of North America, Inc. Survey and testing activities were performed in order to locate and evaluate any archaeological remains which might be affected by landfill construction and operation. In addition, a private collection of artifacts originating from the project area was documented. Prehistoric archaeological remains were encountered in the western portion of the study area, and a new site number was designated for these remains, 41 BX 873. Because of prior disturbance to this site, we recommend that no further investigation is needed

Archaeological Survey of Property for the Proposed Eagle Pass International Bridge, Maverick County, Texas

In May 1990, archaeologists for the Center of Archaeological Research, The University of Texas at San Antonio conducted a surface survey and subsurface testing program. at the site of the proposed Eagle Pass international bridge. The survey was conducted for Groves and Associates, Inc., consulting engineers and project planners, for the City of Eagle Pass. Survey and testing activities were performed in order to locate and evaluate any archaeological remains which might be affected by construction of the bridge and associated facilities. In addition, archival research was conducted at the Eagle Pass library and county courthouse in order to assess potential archaeological resources in the area of the proposed bridge site. The project area has been much disturbed by road, railroad, and water treatment facility constructions. No significant prehistoric or historic archaeological remains were identified during the survey and testing. However further machine and hand excavations within the river terraces to examine for deeply buried cultural deposits and conduct geomorphological recording will be required

Archaeological Survey of the Children\u27s Park at the Victoria Municipal Park, Victoria, Texas

During May 1989, personnel from the Center for Archaeological Research, The University of Texas at San Antonio, conducted a pedestrian survey and shovel testing of the area proposed for development of a children\u27s park, a project of the City of Victoria Parks and Recreation Department. The survey was intended to locate any archaeological remains which might be impacted by construction of the children\u27s park. No archaeological sites were identified during the project, and it is recommended that no further archaeological investigations are needed

An Intensive Archaeological Survey of Enchanted Rock State Natural Area Llano and Gillespie Counties, Texas

During February through April 1979, the Center for Archaeological Research, The University of Texas at San Antonio, carried out an intensive archaeological survey at Enchanted Rock State Natural Area, Llano and Gillespie Counties, Texas. A summary of the 120 newly recorded sites is presented, along with more detailed information on shovel testing, auger testing and two excavated sites. Data from faunal and constant volume analyses at the excavated sites are described and tabulated. Appendices include documentation of a local collection, an artifact inventory from an earlier survey, and an analysis of phytoliths from one of the excavated sites

Archaeological Salvage Research at 41BX901, a Prehistoric Quarry in Bexar County, Texas

During the months of October and November, 1990, staff members and volunteers of the Center of Archaeological Research (CAR), The University of Texas at San Antonio (UTSA), conducted surface survey, mapping, subsurface testing and private collection research at 41 BX 901 and surrounding areas. 41 BX 901 is an extensive prehistoric chert stone quarry in northeastern Bexar county, Texas. The site had been selected for construction of a new middle school by the Northeast Independent School District (NEISD). Survey and testing research was performed in order to evaluate 41 BX 901 and to locate any additional archaeological remains which might be affected by school construction and operation. Extensive prehistoric archaeological remains were encountered at 41 BX 901. Surface and subsurface testing at the site produced abundant lithic remains which indicate lithic procurement and the initial stages of tool fabrication took place here during prehistoric times. However, time-diagnostic artifacts were not recovered from 41 BX 901. Chronological placement of the site depends upon neighboring, more securely dated sites which, it is proposed in this report, had a functional relationship with 41 BX 901. Although 41 BX 901 is one of the most impressive quarries yet documented in this region, the site has been largely destroyed by school construction. 41 BX 905, recorded as part of this project and likely a continuation of 41 BX 901 on neighboring property, is well preserved and will be proposed for national register status. No further archaeological research is recommended for 41 BX 901 due to the destruction of the site. Two neighboring sites, 41 BX 903 and 41 BX 905, merit national register status and protection from development and looting

Archaeological Testing at Two Well Locations in New Braunfels, Comal County, Texas

In March 1989, archaeologists from the Center for Archaeological Research, The University of Texas at San Antonio conducted a subsurface testing program at two localities proposed for well drilling by the Edwards Underground Water District in New Braunfels, Texas. The testing was done to locate and evaluate any archaeological remains which might be affected by well drilling. Prehistoric archaeological remains were encountered at Well Locality 1, but Well Locality 2 was devoid of any cultural materials. No significant damage to archaeological resources is expected with the drilling of the proposed wells. However, monitoring the drilling operation at Well Locality 1 is recommended if subsurface disturbance by heavy equipment is expected in the area of site 41 CM 25

Excavations at 41LK67 a Prehistoric Site in the Choke Canyon Reservior, South Texas

In 1977-1978 excavations were conducted at 41 LK 67 in Live Oak County, south Texas, by the Center for Archaeological Research, The University of Texas at San Antonio. The investigation of this prehistoric archaeological site was part of an extensive program of reconnaissance and excavation necessitated by the construction of the Choke Canyon Reservoir on the Frio River by the Bureau of Reclamation. The site is situated in shallow colluvial deposits capping an old terrace remnant of the Frio River. The excavations involved 193 m2 in three separate areas and revealed Late Prehistoric and Late Archaic components. Recognizably older artifacts (including patinated chert flakes) from the surface and from excavations may represent older disturbed components or artifacts collected prehistorically from nearby sites. Radiocarbon dates, with medians ranging from 1590 to 660 B.C. (MASCA correction) are available only from the Late Archaic component. The principal kinds of debris recovered from the excavations are fire-cracked rock, cores and chipping debris, shells of snails and freshwater mussels, plainware potsherds, and chipped stone tools. Mussel shell was surprisingly abundant; more than 9000 specimens, including 3000 specimens identified taxonomically, were recovered. Fish otoliths were the only animal bones preserved, except for a few recent, intrusive elements. Debris frequencies from the two larger excavation blocks (Areas A and B) were factor analyzed. In most cases the analysis showed the strongest covariation occurring among different classes of chipping debris. For Area C factor analysis indicated that the strongest spatial patterning occurred in the upper part of the deposits. Unfortunately, the analysis was not particularly successful in defining activity sets. The small collection of chipped stone tools was examined microscopically. Two tool classes in particular, distally beveled tools (gouges) and quadrilateral bifaces (beveled knives) seem to represent more functionally specific tool forms, but other hafted bifaces (projectile points) show a wide range of use wear mostly unrelated to projectile use

3D printing the future: scenarios for supply chains reviewed

Purpose: The aim of this paper is to evaluate existing scenarios for 3D Printing in order to identify the “white space” where future opportunities have not been proposed or developed to date. Based around aspects of order penetration points, geographical scope and type of manufacturing, these gaps are identified. Design/methodology/approach: A structured literature review has been carried out on both academic and trade publications. As of the end of May 2016, this identified 128 relevant articles containing 201 future scenarios. Coding these against aspects of existing manufacturing and supply chain theory has led to the development of a framework for identify “white space” in existing thinking. Findings: The coding shows that existing future scenarios are particularly concentrated on job shop applications and pull based supply chain processes, although there are fewer constraints on geographical scope. Five distinct areas of “white space” are proposed, reflecting various opportunities for future 3DP supply chain development. Research limitations: Being a structured literature review, there are potentially articles not identified through the search criteria used. The nature of the findings is also dependent upon the coding criteria selected. However, these are theoretically derived and reflect important aspect of strategic supply chain management. Practical implications: Practitioners may wish to explore the development of business models within the “white space” areas. Originality/value: Currently, existing future 3DP scenarios are scattered over a wide, multi-disciplinary literature base. By providing a consolidated view of these scenarios, it is possible to identify gaps in current thinking. These gaps are multidisciplinary in nature and represent opportunities for both academics and practitioners to exploit

Industrial Additive Manufacturing: a manufacturing systems perspective

As Additive Manufacturing becomes increasingly prevalent in commercial manufacturing environments, the need to effectively consider optimal strategies for management is increased. At present most research has focused on individual machines, yet there is a wealth of evidence to suggest competitive manufacturing is best managed from a systems perspective. Through 14 case studies developed with four long-established Additive Manufacturing companies this paper explores the conduct of Industrial AM in contemporary manufacturing environments. A multitude of activities, mechanisms, and controls are identified through this detailed investigation of Additive Manufacturing operations. Based on these empirical results a general four component Industrial Additive Manufacturing System is developed, together with the identification of potential strategic opportunities to enhance future manufacturing
