Archaeological Survey of Upper Leon Creek Terraces, Bexar County, Texas

In June and July 1994, the Center for Archaeological Research (CAR) of The University of Texas at San Antonio (UTSA) conducted an archaeological survey on a 147-acre tract of land along Leon Creek in northern San Antonio for Pape-Dawson Engineers. The archaeological work was needed for compliance with U. S. Army Corps of Engineers permit requirements before construction of a water storage facility. Four archaeological sites (41BX40, 4IBX47 , 4IBX48, and 4IBX50) had been recorded within this area in 1970 by avocational archaeologists. Additionally, CAR staff members conducted a brief reconnaissance over a 60-acre portion of the property in 1992. Fieldwork consisted of pedestrian survey, 222 shovel tests, one 1-x-1-m test unit, backhoe trenches, plowing, and a geomorphological study by Lee Nordt of Texas A&M University. Evidence from this work suggests that two of the previously recorded sites, 4IBX40 and 4IBX47, are actually part of a single, largely intact, Early and Middle Archaic period site covering approximately 30 acres of the project area. The single site will retain the trinomial 4IBX47. The site contains three components: a Middle Archaic one in the upper 50 cm of the northern part of the site; an Early Archaic component, also in the upper 50 cm, found in the western part of the site; and a component of unknown age buried approximately 80-120 cm below the surface in the central part of the site. A transitional Archaic projectile point was found outside the boundaries of 4IBX47. Further investigation of this site is recommended before construction of the water storage facility. A series of simulated sampling experiments was also conducted with the shovel test data to evaluate the effectiveness of different sampling designs

Archaeological Survey of Laughlin Air Force Base, Val Verde County, Texas

During the spring of 1994, the Center for Archaeological Research of The University of Texas at San Antonio conducted a 100-percent pedestrian survey of Laughlin Air Force Base and the Air Force Recreation Area and Marina in Val Verde County, Texas. In addition to the survey, limited paleontological and geomorphological evaluations were made. One historic site, eight prehistoric sites, and one large site with both prehistoric and historic components were recorded. Additionally, three pre viously recorded sites (De Vore 1993) were revisited. Diagnostic projectile points representing Late Paleoindian through Late Prehistoric occupations were recovered from five of the prehistoric sites. Late-nineteenth- and early twentieth-century artifacts were recovered from the Historic-period sites. Eleven of the 13 total sites are recommended as eligible for nomination to the National Register of Historic Places

Bulletin No. 383 - Cooperative Nutritional Status Studies in the Western Region: I. Nutrient Intake

In 1947, a concerted study of the nutritional status of selected population groups was initiated in the western region of the United States. Previous dietary surveys had indicated that substantial portions of the country\u27s population were consuming lower than recommended levels of essential nutrients. Deficiency diseases that may have nutritional background, such as dental caries, anemia, and rickets, existed. Investigators reported subclinical signs of malnutrition in several areas. Few studies had been made in the West, although reports of high incidence of dental caries and suspected undernutrition had come from several western states. The regional committee thought it evident that the presence of endemic nutritional deficiencies, imbalances, and excesses should be investigated within the western region, and their causes in environmental factors or food habits should be studied. Such conditions might be widespread and cross state lines. Hence the regional approach was appropriate

Genetic implications of reduced survival of male red deer \u3ci\u3eCervus elaphus\u3c/i\u3e under harvest

We use simple, multivariate evolutionary models to evaluate the short-term potential for size-selective harvest to reduce genetic variability and alter life history in cervids. These genetic effects limit sustainable levels of harvest of the animals because they determine how changes in sex ratio, generation length and traits contributing to fitness influence population growth rate and local adaptation. Our analysis of harvest-mediated adaptive evolution employs a genetic approach that parameterizes models with empirical data obtained from European red deer Cervus elaphus. The analysis indicates that harvest, if sufficiently high to reduce the breeding ratio of males to females to below about 15:100, can reduce effective population size to a level that threatens adaptive potential. The reduction in effective size is realized through decreases in both sex ratio of breeders and the age of breeding males. Predicted selective effects of harvest on body size indicates a weak potential to alter most life-history traits over 10 generations under two harvest scenarios; the patterns suggest that current modes of harvest are unlikely to produce substantial life-history changes in red deer over 10 or fewer generations unless the genetic influences on red deer traits are considerably higher than those predicted here. Nevertheless, male reproductive success is expected to decline detectably if male harvest rate is sufficiently high (\u3e30%). Collectively, our results imply that harvest methods should permit higher post-hunt male:female ratios (18:100 or higher) and ensure that a sufficient number of larger, older males survive the breeding season. The capacity of selective harvest to alter demography and life history depends heavily on the genetic covariance structure underlying variation in these traits, information that is unknown for many red deer populations. Prudent harvest management should therefore implement and monitor approaches to hunting that aim to conserve life-history variation; meanwhile, use of less selective methods can reduce the risk to long-term adaptive potential and may permit higher sustainable harvest rates

The role of metabolic remodeling in macrophage polarization and its effect on skeletal muscle regeneration

Macrophages are crucial for tissue homeostasis. Based on their activation, they might display classical/M1 or alternative/M2 phenotypes. M1 macrophages produce pro-inflammatory cytokines, reactive oxygen species (ROS), and nitric oxide (NO). M2 macrophages upregulate arginase-1 and reduce NO and ROS levels; they also release anti-inflammatory cytokines, growth factors, and polyamines, thus promoting angiogenesis and tissue healing. Moreover, M1 and M2 display key metabolic differences; M1 polarization is characterized by an enhancement in glycolysis and in the pentose phosphate pathway (PPP) along with a decreased oxidative phosphorylation (OxPhos), whereas M2 are characterized by an efficient OxPhos and reduced PPP. Recent Advances: The glutamine-related metabolism has been discovered as crucial for M2 polarization. Vice versa, flux discontinuities in the Krebs cycle are considered additional M1 features; they lead to increased levels of immunoresponsive gene 1 and itaconic acid, to isocitrate dehydrogenase 1-downregulation and to succinate, citrate, and isocitrate over-expression

Anomalous temperature dependence of surface tension and capillary waves at liquid gallium

The temperature dependence of surface tension \gamma(T) at liquid gallium is studied theoretically and experimentally using light scattering from capillary waves. The theoretical model based on the Gibbs thermodynamics relates the temperature derivative of \gamma to the surface excess entropy -\Delta S. Although capillary waves contribute to the surface entropy with a positive sign the effect of dipole layer on \Delta S is negative. Experimental data collected at a free Ga surface in the temperature range from 30 to 160 C show that the temperature derivative of the tension changes sign near 100 C.Comment: 11 pages, 1 Postscript figure, submitted to J.
