Comparing Caddo and Coles Creek Pottery Using Petrographic Analysis

Pottery classified as “Coles Creek Incised” is common both to the earliest Caddo sites along the Red River and to contemporary sites in the Lower Mississippi Valley. Although it often is suggested that Coles Creek pottery from the two regions can be distinguished by differences in paste, no detailed comparative studies have been carried out. An initial attempt to identify variation through the use of petrographic analysis was carried out by comparing 50 samples drawn from sites in northwest and central Louisiana. Although no sharp dichotomy was noted between the regions, the study identified distinctions that support the notion that most Coles Creek pottery was made locally and different technological traditions may be represented

Galactic Winds

Galactic winds are the primary mechanism by which energy and metals are recycled in galaxies and are deposited into the intergalactic medium. New observations are revealing the ubiquity of this process, particularly at high redshift. We describe the physics behind these winds, discuss the observational evidence for them in nearby star-forming and active galaxies and in the high-redshift universe, and consider the implications of energetic winds for the formation and evolution of galaxies and the intergalactic medium. To inspire future research, we conclude with a set of observational and theoretical challenges.Comment: Paper to be published in 2005 Annual Review of Astronomy & Astrophysics; revision based on comments from readers and production editor.

Panhypopituitarism : a rare cause of neonatal cholestatic jaundice

Although not uncommon, neonatal cholestatic jaundice is usually caused by congenital anatomical defects of the biliary tree or intrinsic liver pathology. We describe a case of persistent cholestatic jaundice in a six week old female infant caused by panhypopituitarism. To our knowledge this is the first report of hypopituitarism presenting with cholestatic jaundice in Malta. Prolonged obstructive jaundice in the neonatal period should be urgently investigated until a cause is found.peer-reviewe

2008 Field Excavation Final Report Acosta-Durst-Taylor House

The Acosta-Durst-Taylor site (now known as the Durst-Taylor House) is known as one of the earliest occupations in Nacogdoches, TX. The property fronts North Street and is just to the north of Hospital Street (Figure 1). Much of the history of this plot of land and accompanying house, out structures, and other buildings associated with this land is described thoroughly in the site’s National Register of Historic Places nomination form (United States Department of the Interior 2003). What follows is a brief synopsis of the changing landscape of site 41NA182

The relationship between infecting organisms and underlying structural anomalies in children with urinary tract infections

Introduction: Urinary tract infections (UTIs) are a common cause of morbidity in childhood with potential for renal scarring and reflux nephropathy which can lead to hypertension and end-stage renal failure. Aim: The aim of this study was to investigate the relationship between the infecting organism and any underlying anomalies of the urinary tract which may predispose to the development of infections and which may alter the management of children with UTIs. Methods and results: A total of 72 cases of UTI were recorded retrospectively (in- and outpatients), with ages ranging from 3 days to 48 months (mean 9.5, median 5 months). Fifty seven (79%) of patients had their first reported urinary tract infection under the age of 1 year.. Fifty eight (80.6%) were E. coli infections. These presented at an older age than non-E. coli infections. Investigations were abnormal in 31 (43%) cases. The mean age for first infection in patients with abnormal investigations was 7.7 months (median 2 months), younger than those with no renal tract abnormalities. Organisms other than E. coli were rarely found when no significant abnormalities were detected with investigation by US and MCUG and this was a statistically significant difference (p<0.001). Renal scarring was identified in 10 (13.9%) patients. Discussion: This study confirms that non-E. coli UTI is associated with underlying renal pathology and that early infections with any organism are more likely to be associated with underlying abnormalities. We also outline an algorithm based on the recent NICE 2007 guidelines which will be adopted by the Paediatric Department, Mater Dei Hospital for the investigation of UTI.peer-reviewe
