OUTCOME MEASURES |
Network measurements were compared using coefficient of variation. Measurements were correlated with scores from the National Public Health Performance Assessment and with LHD demographics. Rankings of tasks, knowledge, and resources were correlated across pairs of LHDs. |
RESULTS |
We found that 11 LHDs exhibited compound organizational structures in which centralized hierarchies were coupled with distributed networks at the point of service. Local health departments were distinguished from random networks by a pattern of high centralization and clustering. Network measurements were positively as... |
CONCLUSIONS |
Shared network patterns across LHDs suggest where common organizational management strategies are feasible. This evidence supports national efforts to promote uniform standards for service delivery to diverse populations.Volumetric analysis of the tympanic isthmus in human temporal bones. |
A volumetric study on the tympanic isthmus and its relationship to temporal bone pneumatization was conducted in 110 serially sectioned temporal bones with and without middle ear pathology. With a microcomputer and digitizing tablet, the area of the tympanic isthmus and the degree of pneumatization in sample sections w... |
A three series-connected transistor model is introduced to understand the electrical characteristics of conventional recess-channel-array transistors (RCATs) and modified RCATs. An RCAT is considered to be a serial connection of three transistors consisting of one bottom transistor and two vertical transistors. The ele... |
OBJECTIVE |
To evaluate the effectiveness of a helium-oxygen mixture (79%He- 21%O(2)) as an aerosolizing compressed gas for beta(2)-agonist therapy in patients with an asthma exacerbation. |
METHODS |
Twenty-four patients in the outpatient department with a mild to moderate exacerbation of asthma were enrolled. The patients were randomly divided into an experimental group (13 cases) and a control group (11 cases). The experimental group inhaled Berotec with heliox-driven, and the control group inhaled Berotec with c... |
RESULTS |
The results of spirometric parameters and arterial blood-gas analysis were measured. In the mild to moderate asthma patients, no statistical differences between the two groups for forced vital capacity (FVC), forced expired volume in one second (FEV(1)), and expiratory flow in 50% forced vital capacity (FEF(50)) were p... |
CONCLUSIONS |
Compared with the traditional inhalation of beta(2)-agonist therapy using compressed air-driven, the method of inhaling beta(2)-agonist with heliox-driven has more obvious benefits for those suffering from severe asthma. This is likely due to the cooperative effects between inhaling heliox on its physical gas propertie... |
Hydroxyapatite (HAp) has been used for several decades in the biomedical industry for dental and orthopedic implants owing to it being the basic component of bone (about 70%). The effect of load on the tribological behavior of highly porous plasma sprayed Ca10 (PO4).6(OH)2 (HAp) deposited onto a Ti6Al4V alloy substrate... |
Within the Macroscelidea 15 species of elephant‐shrews are recognized, of which nine occur in the southern African subregion. The Cape rock elephant‐shrew (Elephantulus edwardii) is the only strictly endemic South African elephant‐shrew species. Recent distribution data suggest that E. edwardii is continuously distribu... |
The prevalence of H. pylori infection in 200 dyspeptic patients undergoing upper G.I. endoscopy was investigated by histology and rapid urease test. H. pylori was associated with 86% cases of chronic gastritis, 84.6% cases of duodenal ulcers and 78.5% of gastric ulcers. None of the 15 histologically normal gastric biop... |
We have previously shown that CD8(+)gammadelta T cells decrease late allergic airway responses, airway eosinophilia, T helper 2 cytokine expression and increase interferon-gamma (IFN-gamma) expression. We hypothesized that the effects of CD8(+)gammadelta T cells were IFN-gamma mediated. Brown Norway rats were sensitize... |
In his 1840 review of Hawthorne's Twice-Told Tales, Edgar Allan Poe imposed a distinction between tales and essays which has haunted Hawthorne scholarship for more than a century and a hale Now we rarely discuss Hawthorne's "essays," and one of the reasons that we don't is Poe's emphasis on "their discrepancy with that... |
Synthesizing the movements of a responsive virtual character in the event of unexpected perturbations has proven a difficult challenge. To solve this problem, we devise a fully automatic method that learns a nonlinear probabilistic model of dynamic responses from very few perturbed walking sequences. This model is able... |
The threat posed by insiders deliberately or inadvertently misusing their knowledge and access to sensitive information is a major security challenge. Finding effective, acceptable and affordable ways to manage the insider threat is non-trivial, involving the use of controls that range from technical to procedural. To ... |
BACKGROUND |
Endoscopic ultrasound (EUS) is an important new tool in the staging of pancreatic malignancies. Using new curved linear-array instruments, real-time fine-needle aspiration biopsy (RTFNA) of pancreatic lesions can be performed. |
METHODS |
Forty-five patients with pancreatic lesions (22 males and 23 females) underwent staging with the Olympus EUM-20 (Olympus America Corp, Melville, NY) followed by EUS-RTFNA with the Pentax FG-32PUA (Pentax-Precision Instrument Corp, Orangeburg, NY) and the 22-gauge GIP needle (GIP Medizin Technik, Grassau, Germany). |
RESULTS |
EUS tumor stages were as follows: TO, n = 1; T1, n = 8; T2, n = 9; and T3 n = 27. Aspiration attempts were unsuccessful in four patients (two technical failures and two inadequate specimens). The remaining 41 lesions (mean size, 3.3 cm) were aspirated under EUS guidance (median passes, three) and the cytologic diagnose... |
CONCLUSION |
EUS-guided RTFNA is a safe and accurate method for performing pancreatic biopsy. It should be considered in patients with suspected pancreatic malignancies in whom a tissue diagnosis is required or when other modalities have failed. EUS-RTFNA allows for local staging and tissue diagnosis in one procedure.INTERIOR DESIG... |

Large dark prismatic crystals (P 1 ¯ ) consisting of closely packed centrosymmetric [Cu(4,7-dichloroquinoline)2]2Br4 binuclear units are formed when 4,7-dichloroquinoline (DCQ, C9H5NCl2) binds copper(II). Cu2+ adopts a strongly distorted square pyramidal coordination geometry, perturbed by electrostatic interactions wi... |
Wear limits the life-span of many mechanical devices with moving parts. To reduce wear, lubricants are frequently enriched with additives, such as zinc phosphates, that form protective films on rubbing surfaces. Using first-principles molecular dynamics simulations of films derived from commercial additives, we unravel... |

Logic programming has traditionally lacked devices for expressing mutually exclusive goals and queries. We address this limitation by adopting choice-disjunctive goal formulas of the form $G_1 + G_2$ where $G_1, G_2$ are goals and + is a linear logic connective. These goals has the following operational semantics: choo... |
The purpose of this paper is to broaden the practical notion of Taguchi's Quality Loss Function (QLF) from a static, one‐stage concept into a dynamic time‐varying tool. Taguchi challenged the old‐age notion of engineering tolerance and proposed a quadratic QLF that quantifies loss to society, caused by deviation of pro... |

We compare typical properties of the hyperbolic and quasi-hyperbolic attractors with the properties of the particular attractor observed in the classical dry friction oscillator excited by external harmonic drive [Popp & Stelter, 1990a; Hinrichs et al., 1998; Oestreich et al., 1996]. Our analysis shows that the main co... |
