Performance is a major issue in the acceptance of object-oriented and relational database systems aimed at engineering applications such as computer-aided software engineering (CASE) and computer-aided design (CAD). Because traditional database systems benchmarks are inapproriate to measure performance for operations on engineering objects, we designed a(More)
This study was conducted to characterize the chemistry associated with the decomposition of human remains with the objective of identifying time-dependent biomarkers of decomposition. The purpose of this work was to develop an accurate and precise method for measuring the postmortem interval (PMI) of human remains. Eighteen subjects were placed within a(More)
Cerebral amyloid deposits from five patients with presenile or senile cerebral disease of the Alzheimer type were stained with uranyl acetate and lead citrate or with periodic acid-thiocarbohydrazidesilver proteinate, and examined with traditional highresolution electron microscopy and with a goniometer tilting stage. In addition to a carbohydrate-rich(More)
Preweanling and postweaning offspring of gerbil parents fed Purina Laboratory Chow or Pooch dog food show selective preference for odors coming from other animals of these same diets. Odors with differential quality include whole animal, cage material and ventral scent gland sebum. Apparently diet alters chemosignals, even those from a specialized scent(More)
In 2 studies (ns = 10, 9) college students were trained using biofeedback to lower or to raise finger temperature. Successful subjects were then asked to do distracting intellectual tasks, while simultaneously retaining the learned temperature changes. Results indicated that these changes could be maintained without detectable decreases in problem-solving(More)
The decision to outsource the manufacture of an entire device can be difficult, yet the advantages of this business strategy are huge. The important elements of the process are examined here so that companies can adopt this approach with confidence.
