Hemosuccus Pancreaticus as a Rare Complication of Bariatric Surgery.

Hemosuccus pancreaticus is a rare cause of gastrointestinal bleeding from the duct of Wirsung into the duodenum via the ampulla of Vater. Hemosuccus pancreaticus is difficult to diagnose because the bleeding is usually intermittent, and the clinical findings are often discordant. Patients present with pain, either left upper quadrant or epigastric, and bleeding, which may present as melena, bright red blood per rectum, or even shock, if the hemorrhage is severe. Hemosuccus pancreaticus is usually caused by rupture of a pseudoaneurysm of a peri-pancreatic artery, often the splenic artery, in the setting of pancreatitis; other causes are very rare. In this report, for the first time to our knowledge, we present a case of hemosuccus pancreaticus that occurred as a complication of bariatric surgery

Cities of God in northern Asia minor Using Starks social theories to reconstruct Peters communities

This article used seven hypotheses from R. Stark�s Cities of God (2007) as a heuristic tool toinvestigate the rise of Christianity in the five Roman provinces mentioned in 1 Peter 1:1. It affirmed that the Christian communities in these provinces were located in an urban, not rural, setting. Building on the research of Hort and Hemer, seven major cities in these provinces were proposed to test Stark�s hypotheses with. These cities are Sinope and Amisus in Pontus, Ancyra in Galatia, Caesarea Mazaca in Cappadocia, Dorylaeum in Asia and Nicea and Nicomedia in Bithynia. An important factor noted in several of these cities was their prominence as a commercial seaport and the presence of a Diaspora Jewish community. Utilising this methodological approach helped to elucidate more fully the audience of 1 Peter�s geographic and historical background

Aging and Health: An Examination of Differences between Older Aboriginal and non-Aboriginal People

The Aboriginal population in Canada, much younger than the general population, has experienced a trend towards aging over the past decade. Using data from the 2001 Aboriginal Peoples Survey (APS) and the 2000/2001 Canadian Community Health Survey (CCHS), this article examines differences in health status and the determinants of health and health care use between the 55-and-older Aboriginal population and non-Aboriginal population. The results show that the older Aboriginal population is unhealthier than the non-Aboriginal population across all age groups; differences in health status, however, appear to converge as age increases. Among those aged 55 to 64, 7 per cent of the Aboriginal population report three or more chronic conditions compared with 2 per cent of the non-Aboriginal population. Yet, among those aged 75 and older, 51 per cent of the Aboriginal population report three or more chronic conditions in comparison with 23 per cent of the non-Aboriginal population.Aboriginal people, health status, health care use

Preliminary calculation of solar cosmic ray dose to the female breast in space mission

No regulatory dose limits are specifically assigned for the radiation exposure of female breasts during manned space flight. However, the relatively high radiosensitivity of the glandular tissue of the breasts and its potential exposure to solar flare protons on short- and long-term missions mandate a priori estimation of the associated risks. A model for estimating exposure within the breast is developed for use in future NASA missions. The female breast and torso geometry is represented by a simple interim model. A recently developed proton dose-buildup procedure is used for estimating doses. The model considers geomagnetic shielding, magnetic-storm conditions, spacecraft shielding, and body self-shielding. Inputs to the model include proton energy spectra, spacecraft orbital parameters, STS orbiter-shielding distribution at a given position, and a single parameter allowing for variation in breast size

Random and exhaustive generation of permutations and cycles

In 1986 S. Sattolo introduced a simple algorithm for uniform random generation of cyclic permutations on a fixed number of symbols. This algorithm is very similar to the standard method for generating a random permutation, but is less well known. We consider both methods in a unified way, and discuss their relation with exhaustive generation methods. We analyse several random variables associated with the algorithms and find their grand probability generating functions, which gives easy access to moments and limit laws.Comment: 9 page

Remaking Medical Geography

Medical geography has a long tradition of examining the spatial distribution of diseases and medical care resources. With the shifts in theory, methodology, and changing health issues, medical geography is remaking itself in three complementary modalities. First, in taking into account new theories it is remaking itself as the geography of health and health care. Secondly, in taking into account new methodologies, it is contributing to the global interest in seeking new ways of understanding the spatial distribution of diseases and medical resources. Thirdly, in focusing on issues such as HIV/AIDS, health and the environment and vulnerable populations such as the elderly and immigrant women, it is increasingly contributing to public policy at various geographic scales

Pultrusion Die Assembly

This invention relates generally to pultrusion die assemblies, and more particularly, to a pultrusion die assembly which incorporates a plurality of functions in order to produce a continuous, thin composite fiber reinforced thermoplastic material. The invention is useful for making high performance thermoplastic composite materials in sheets which can be coiled on a spool and stored for further processing

Leading Transportation Indicators: Forecasting Waterborne Commerce Statistics Using Lock Performance Data

This paper develops and applies a forecasting model for transportation data based on the leading economic indicators literature. The specific application is to forecast river tonnages. Waterborne commerce data reflect tonnages of commodities moved on various rivers and in various directions. They are released after the Lock Performance Monitoring System data which reflect tonnages moving through specific locks. The model presented here forecasts waterborne commerce data from lock performance data. The results suggest that even a very simple model can provide precise forecasts

The Effects of Linear Microphone Array Changes on Computed Sound Exposure Level Footprints

Airport land planning commissions often are faced with determining how much area around an airport is affected by the sound exposure levels (SELS) associated with helicopter operations. This paper presents a study of the effects changing the size and composition of a microphone array has on the computed SEL contour (ground footprint) areas used by such commissions. Descent flight acoustic data measured by a fifteen microphone array were reprocessed for five different combinations of microphones within this array. This resulted in data for six different arrays for which SEL contours were computed. The fifteen microphone array was defined as the 'baseline' array since it contained the greatest amount of data. The computations used a newly developed technique, the Acoustic Re-propagation Technique (ART), which uses parts of the NASA noise prediction program ROTONET. After the areas of the SEL contours were calculated the differences between the areas were determined. The area differences for the six arrays are presented that show a five and a three microphone array (with spacing typical of that required by the FAA FAR Part 36 noise certification procedure) compare well with the fifteen microphone array. All data were obtained from a database resulting from a joint project conducted by NASA and U.S. Army researchers at Langley and Ames Research Centers. A brief description of the joint project test design, microphone array set-up, and data reduction methodology associated with the database are discussed
