Ultrasound examination is a valuable method in diagnosing visceral vasoconstriction of atherosclerotic origin, as well as constriction related to the compression of the celiac trunk. Given the standard stenosis recognition criteria of >70%, the increase in peak systolic velocity (PSV) over 200 cm/s in the celiac trunk; of PSV > 275 cm/s in the superior mesenteric artery, and of PSV > 250 cm/s i...

CM: Problem Management is a detailed problem management process model to be utilised within corrective maintenance. It has been developed at ABB and evaluated for its industrial relevance within 17 non-ABB organisations. In this paper, we present the evaluation results of CM: Problem Management. Our primary goal is to confirm its industrial relevance. Our secondary goal is to establish current ...

Two new tools have been employed to diagnose and actively perturb fluctuations in the edge plasma of the Alcator C-Mod tokamak. A mirror Langmuir probe [1, 2, 3] has been used to characterize edge fluctuations and transport with unprecedented detail. In addition, a new Shoelace antenna [4, 5] provides a direct drive to actively probe these fluctuations at a specific k⊥ (1.5 cm ) within a broad ...

We perform low-temperature electrical transport measurements on gated, quasi-2D graphite quantum dots. In devices with low contact resistances, we use longitudinal and Hall resistances to extract carrier densities of 9.2-13 x 10(12) cm(-2) and mobilities of 200-1900 cm(2)/V.s. In devices with high resistance contacts, we observe Coulomb blockade phenomena and infer the charging energies and cap...

The paper provides comparative data concerning sleeping distance in relation to sexual state and hierarchical dominance in the Arctic blue fox. Increasing levels of vulval swelling and electrical resistance of vaginal tract were inversely related to sleeping distance between the highest-ranking male and each female on heat. A mating pair typically slept no further than 50 cm from each other. On...

Radiation quality indices (QI), tumor control probability (TCP), and normal tissue complication probability(NTCP) were evaluated for ideal single and double plane HDR interstitial implants. In the analysis, geometrically-optimized at volume (GOV) treatment plans were generated for different values of inter-source-spacing (ISS) within the catheter, inter-catheter-spacing (ICS), and inter-plane-s...

Cerebral malaria (CM) in children is associated with a high mortality and long-term neurocognitive sequelae. Both erythropoietin (Epo) and vascular endothelial growth factor (VEGF) have been shown to be neuroprotective. We hypothesized that high plasma and cerebrospinal fluid (CSF) levels of these cytokines would prevent neurological sequelae in children with CM. We measured Epo, VEGF, and tumo...

BACKGROUND Epidemiological and health services research often use International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes to identify patients with clinical conditions in administrative databases. We determined whether there are systematic variations between stroke patient clinical diagnoses and ICD-9-CM codes, stratified by hospital characteristics and ...

In northern Yellowstone National Park, quaking aspen (Populus tremuloides) stands were dying out in the late 20th century following decades of intensive browsing by Rocky Mountain elk (Cervus elaphus). In 1995–1996 gray wolves (Canis lupus) were reintroduced, joining bears (Ursus spp.) and cougars (Puma concolor) to complete the guild of large carnivores that prey on elk. This was followed by a...

PURPOSE Laparoscopic radical nephrectomy has emerged as a standard of care in appropriate candidates with clinical stage T1 renal tumors (7 cm or less). Herein we present our experience with laparoscopic radical nephrectomy for clinical stage T2 tumors (greater than 7 cm). MATERIALS AND METHODS Patients undergoing laparoscopic radical nephrectomy between September 1997 and July 2003 were retr...
