Analysis of Squirrel Cage Motor with Broken Bars and Rings

Abstract — In the paper results of calculations and measurements of an induction motor with broken bars or rings are presented. The calculations were made using the circuit and circuit-field method. The stator current as diagnostic signal for estimation of a damaged squirrel cage motor has been taken. For separation of additional components in the stator current arising at a rotor asymmetry low-pass filters of Mathcad program were used.
Knowledge Management in Autonomic Database Performance Tuning

Databases are growing rapidly in scale and complexity. High performance, availability and further policy goals need to be satisfied under any circumstances to please customers. In order to tune the DBMS within their complex environments highly skilled database administrators are required. Unfortunately, they are becoming rarer and more and more expensive. Hence, improving performance analysis and moving towards automation of problem resolution requires a more intuitive and flexible source of decision making. This paper points out the importance of knowledge for autonomic database tuning, proposes a component-based knowledge model and briefly presents first prototypical evaluation results.
Theory of mind in schizophrenia: Exploring neural mechanisms of belief attribution

Background: Although previous behavioral studies have shown that schizophrenia patients have impaired theory of mind (ToM), the neural mechanisms associated with this impairment are poorly understood. This study aimed to identify the neural mechanisms of ToM in schizophrenia, using functional magnetic resonance imaging (fMRI) with a belief attribution task. Methods: In the scanner, 12 schizophrenia patients and 13 healthy control subjects performed the belief attribution task with three conditions: a false belief condition, a false photograph condition, and a simple reading condition. Results: For the false belief versus simple reading conditions, schizophrenia patients showed reduced neural activation in areas including the temporoparietal junction (TPJ) and medial prefrontal cortex (MPFC) compared with controls. Further, during the false belief versus false photograph conditions, we observed increased activations in the TPJ and the MPFC in healthy controls, but not in schizophrenia patients. For the false photograph versus simple reading condition, both groups showed comparable neural activations. Conclusions: Schizophrenia patients showed reduced task-related activation in the TPJ and the MPFC during the false belief condition compared with controls, but not for the false photograph condition. This pattern suggests that reduced activation in these regions is associated with, and specific to, impaired ToM in schizophrenia.
Factors Associated With Recurrence and Survival in N0 Gastric Cancer.

innovations were used on an urgent basis due to patient need. Thus the choice is to expect every innovation to receive IRB approval and accept that many surgeons will not complete this step, or develop internal processes such as we have done to have some element of institutional control or oversight. The second comment by Sood et al is that we did not ‘‘explicitly mention an objective methodology that monitors safety during implementation. ’’ Although statistical process monitoring is an excellent tool, the purpose of our article was not to discuss safety monitoring methodologies. Furthermore, statistical process monitoring would not have been applicable to our innovations given the small sample sizes. Finally, although we strongly agree with the aim of adoption of therapeutic innovations only after ‘‘comparative outcomes with immediate to long-term follow-up,’’ this does not reflect the current reality. Until that IDEAL world is reached, our program provides our institution, and we hope it would also provide other institutions, with a mechanism for accountability during the introduction of surgical innovations.
Intrinsic Kinetics Study of Biogas Methanation Coupling with Water Gas Shift over Re-Promoted Ni Bifunctional Catalysts

The intrinsic kinetics of biogas methanation coupling with water gas shift over Re-promoted Ni bifunctional catalysts were investigated in this study. The catalysts were prepared through co-impregnation of Ni and Re precursors on the H2O2-modified manganese sand. The experiments were performed in a fixed bed reactor under the assorted reaction conditions of 300–400 °C, 0.1–0.3 MPa, and a 0.6–1.0 H2/CO ratio. The effect of gas internal and external diffusion on the performance of methanation coupling with water gas shift was examined by changing catalyst particle size and gas hourly space velocity (GHSV) and further verified by the Weisz–Prater and Mears criterion, respectively. It was found that the internal and external diffusions were eliminated when the catalyst particle size was 12–14 meshes and GHSV was 2000 h−1. Three kinetics models including the empirical model (EM), synergetic model (SM), and independent model (IM) were proposed, and 25 sets of experimental data were obtained to solve the model parameters. By mathematical fitting and analysis, it was discovered that the fitting situation of the three kinetics models was in the order of EM > SM > IM, among which EM had the highest fitting degree of 99.7% for CH4 and 99.9% for CO2 with the lowest average relative error of 8.9% for CH4 and 8.7% for CO2. The over 30% of average relative error for CO2 in IM might exclude the possibility of the Langmuir–Hinshelwood water gas shift mechanism in the real steps of biogas methanation coupling with water gas shift over Re-promoted Ni catalysts.
Hospice Core Professions’ Views on Interdisciplinary Teams: A Qualitative Investigation

ABSTRACT The hospice interdisciplinary team (IDT) has been recognized as an ideal model for interprofessional collaboration. To address the manner in which interdisciplinary practices are perceived by team members, this study explored profession-based similarities and differences in perceptions among the four core hospice IDT members (physicians, nurses, social workers, and spiritual care providers) as well as experiences on the IDT. Semistructured interviews with 20 hospice professionals, 5 from each profession, were completed. Findings suggested that while hospice professions share some perceptions and experiences about hospice team membership, strengths of and barriers to teamwork, and individual members’ contribution to the team, significant profession-based differences exist largely in the area of hospice team membership beyond the core members, type of language and descriptions used, perceptions of causes and effects of barriers to teamwork, and understandings of how team effectiveness is evaluated. Changes at the team-based, organizational, policy, and educational levels are needed to further maximize strengths of individual hospice IDT member and team qualities.
A two stage structure for high order multi-bit /spl Sigma/-/spl Delta/ ADC with multiplier-less digital correction logic

This paper presents the design methodology of /spl Sigma/-/spl Delta/ ADC that uses a high order single bit first stage, and a multi bit first order second stage and introduces a novel multiplier-less high order digital correction block. The selection of the number of bits and order is done by design graphs that are obtained through numerous simulations under practical tolerances in implementation parameters. By using an example of a 3rd order first stage with a 5-bit second stage, we show that the over-sampling ratio can be reduced to (=<32) while achieving a high bit resolution (>16 bits) for 2% mismatch implementation tolerances between analog and digital parts. Our approach results in an overall increase in the maximum baseband frequency, while the additional digital correction logic is minimal. <<ETX>>
Shamanism

First published in 1951, "Shamanism" soon became the standard work in the study of this mysterious and fascinating phenomenon. Writing as the founder of the modern study of the history of religion, Romanian emigre--scholar Mircea Eliade (1907-1986) surveys the practice of Shamanism over two and a half millennia of human history, moving from the Shamanic traditions of Siberia and Central Asia--where Shamanism was first observed--to North and South America, Indonesia, Tibet, China, and beyond. In this authoritative survey, Eliade illuminates the magico-religious life of societies that give primacy of place to the figure of the Shaman--at once magician and medicine man, healer and miracle-doer, priest, mystic, and poet. Synthesizing the approaches of psychology, sociology, and ethnology, "Shamanism" will remain for years to come the reference book of choice for those intrigued by this practice. "
Problems in the coupling of eye and hand in the sequential movements of children with Developmental Coordination Disorder.

BACKGROUND Shifting gaze and attention ahead of the hand is a natural component in the performance of skilled manual actions. Very few studies have examined the precise co-ordination between the eye and hand in children with Developmental Coordination Disorder (DCD). METHODS This study directly assessed the maturity of eye-hand co-ordination in children with DCD. A double-step pointing task was used to investigate the coupling of the eye and hand in 7-year-old children with and without DCD. Sequential targets were presented on a computer screen, and eye and hand movements were recorded simultaneously. RESULTS There were no differences between typically developing (TD) and DCD groups when completing fast single-target tasks. There were very few differences in the completion of the first movement in the double-step tasks, but differences did occur during the second sequential movement. One factor appeared to be the propensity for the DCD children to delay their hand movement until some period after the eye had landed on the target. This resulted in a marked increase in eye-hand lead during the second movement, disrupting the close coupling and leading to a slower and less accurate hand movement among children with DCD. CONCLUSIONS In contrast to skilled adults, both groups of children preferred to foveate the target prior to initiating a hand movement if time allowed. The TD children, however, were more able to reduce this foveation period and shift towards a feedforward mode of control for hand movements. The children with DCD persevered with a look-then-move strategy, which led to an increase in error. For the group of DCD children in this study, there was no evidence of a problem in speed or accuracy of simple movements, but there was a difficulty in concatenating the sequential shifts of gaze and hand required for the completion of everyday tasks or typical assessment items.
Low-Loss Millimeter-Length Waveguides and Grating Couplers in Single-Crystal Diamond

We report on the design, fabrication, and characterization of millimeter-length strip waveguides with monolithic grating couplers in commercially available synthetic single-crystal diamond. To minimize the device footprint and the influence of the wafer wedge of the single-crystal diamond thin plate, we adopt a curled waveguide layout. The devices are fabricated using electron-beam lithography and reactive-ion etching. To improve the e-beam patterning accuracy of the grating etch masks, we apply proximity-effect compensation on the gratings and tapers. The linear characterization results indicate a waveguide attenuation of 6.5 dB/mm and a grating transmission of -6.3 dB in the fiber-optic communication C band. These results demonstrate the feasibility of fabricating long waveguides and integrated grating couplers in single-crystal diamond. Our research findings would be beneficial for further exploring quantum and nonlinear optics in integrated single-crystal diamond devices.
Biochemical Evaluation of Genotoxic Biomarkers for 2-Deoxyribonolactone-Mediated Cross-Link Formation with Histones

Numerous environmental carcinogens involve radical formation interacting with DNA to produce 2-deoxyribonolactone (dL), a major type of oxidized abasic site, implicated in DNA strand breaks, mutagenesis, and formation of covalent DNA–protein cross-links (DPC). Studies showed major dL-specific DPC occurred due to reactions with DNA polymerase β (Polβ) dependent on native conformation, while other DPC formed involved nonenzymatic reactions of DNA binding proteins with dL lesions. Polβ appeared to play a major role in alleviating the cytotoxic effects of neocarzinostatin, which was used as a dL-producing agent. When a duplex DNA containing a dL at a site-specific position was incubated with purified histones, DPC were formed between dL and each histone protein, including H1, H2A, H2B, H3, and H4. Comparative kinetic analysis of DPC formation with histones and Polβ revealed two distinct mechanisms of dL-mediated DPC formation. The rate of DPC formation with Polβ was approximately two orders of magnitude higher than that with various histone proteins. These results indicate that catalytic activity of Polβ mediates rapid DPC formation between dL and this DNA repair enzyme, whereas nonenzymatic reactions of dL with histones form DPC more slowly. The abundance of histones and their constant interaction with DNA may nevertheless yield significant levels of DPC with dL, as biomarkers of dL-induced cytotoxicity. Overall, data suggest that occurrence of dL-mediated DPC with histones may contribute to the genotoxic effects of dL in DNA.
Platelet-Rich Plasma: A Promising Product for Treatment of Peripheral Nerve Regeneration After Nerve Injury

ABSTRACT Nerve regeneration includes regrowth of injured axons as well as myelination, restoration of synaptic connections and recovery of physiological functions. Platelet-rich plasma (PRP) is prepared from the patient's own blood and contains growth factors that influence wound healing and used in various surgical fields including oral and maxillofacial surgery. When platelets are activated either ex vivo or in vivo, growth factors and proteins were released from platelets' alpha granules. Recent studies proved that PRP could promote regeneration of injured peripheral nerve. This review focuses on current trials using PRP to promote nerve regeneration and repairment, and proposes potential clinical application of PRP for nerve injury in the future.
Effective Cutoffs for Detecting Random, Partially Random, and Nonrandom 370-Item MMPI–2 Short Form Protocols

The ability of the 370-item short form MMPI–2 (Butcher, Graham, Ben-Porath, Tellegen, Dahlstrom, & Kaemmer, 2001) validity scales to detect random protocols was investigated using samples of 500 nonrandom protocols, 250 half-random protocols, and 250 all-random protocols. The long-form cutoff of VRIN ⩾ 80 was unable to detect protocols with either level of randomness. The long-form cutoffs of Fp ⩾ 100 or F ⩾ 100 were able to detect all-random but not half-random protocols. Alternative cutoffs for VRIN, Fp, and F were investigated and short-form subscales of those scales were developed to improve detection of partially random protocols. An algorithm using alternative cutoffs for the scales and the new subscales was highly effective, detecting almost all of the random protocols as well as the nonrandom protocols. A follow-up cross-validation study was conducted that confirmed the effectiveness of the algorithm.
Modeling and Analysis of Network Dynamics in Complex Communication Networks Using Social Network Methods

Modern communication networks are inherently complex in nature. First of all, they have a large number of heterogeneous components. Secondly, their connectivity is extremely dynamic. Nodes can come and go, links can be removed and added over time. Traditional modeling and simulation techniques amalgamate or ignore such dynamics and therefore, are unable to represent them. Complex communication networks are therefore better modeled as mathematical structures called graphs. Modeling as graphs allows for the application of complex techniques such as various network based analysis techniques. While this is a very important and much needed skill for communication networks researchers and engineers, to the best of our knowledge, currently there is no resource describing these details. In this paper, we give a concise but comprehensive review of modeling complex communication networks as graphs. We also show how to apply complex social network analysis on these models besides a demonstration of formal modeling network dynamics.
Cu2ZnSn(S,Se)4 thin films prepared using Cu2ZnSnS4 nanoparticles

Cu2ZnSn(S,Se)4 (CZTSSe) is a compound semiconductor which replaces a part of S in the CZTS crystal by Se. The bandgap varies from 1.05 eV to 1.51 eV depending on the mole ratio between S and Se. In this paper, CZTSSe thin films were prepared by the selenidation of CZTS film, and the Se mole ratio was tuned by changing annealing conditions. The film quality of the obtained CZTSSe was characterized by X-ray diffraction (XRD) and Hall measurements. It was revealed that both the supply of Se vapor pressure and the annealing temperature of CZTS were controlling parameters for the selenidation of the film. The crystal quality of CZTSSe was also influenced by the supply of Se vapor pressure.
The Purple Cauliflower Arises from Activation of a MYB Transcription Factor1[W][OA]

Anthocyanins are responsible for the color of many flowers, fruits, and vegetables. An interesting and unique Purple (Pr) gene mutation in cauliflower (Brassica oleracea var botrytis) confers an abnormal pattern of anthocyanin accumulation, giving the striking mutant phenotype of intense purple color in curds and a few other tissues. To unravel the nature of the Pr mutation in cauliflower, we isolated the Pr gene via a combination of candidate gene analysis and fine mapping. Pr encoded a R2R3 MYB transcription factor that exhibited tissue-specific expression, consistent with an abnormal anthocyanin accumulation pattern in the mutant. Transgenic Arabidopsis (Arabidopsis thaliana) and cauliflower plants expressing the Pr-D allele recapitulated the mutant phenotype, confirming the isolation of the Pr gene. Up-regulation of Pr specifically activated a basic helix-loop-helix transcription factor and a subset of anthocyanin structural genes encoding flavonoid 3’-hydroxylase, dihydroflavonol 4-reductase, and leucoanthocyanidin dioxygenase to confer ectopic accumulation of pigments in the purple cauliflower. Our results indicate that the genetic variation including a Harbinger DNA transposon insertion in the upstream regulatory region of the Pr-D allele is responsible for the up-regulation of the Pr gene in inducing phenotypic change in the plant. The successful isolation of Pr provides important information on the regulatory control of anthocyanin biosynthesis in Brassica vegetables, and offers a genetic resource for development of new varieties with enhanced health-promoting properties and visual appeal.
The Clinical Significance of Caspase Regulation in Acute Leukemia

Disruptions of pathways of programmed cell death, or apoptosis, are increasingly found in malignant cells of both solid and hematologic neoplasms. Caspases belong to a family of cysteine proteases and have emerged as central regulators of the apoptotic cascade. Despite many and diverse signals that can trigger apoptosis, the execution of apoptosis appears to be uniformly mediated through activation of caspase enzymes. Inapproriate expression of cas-pases or malfunctions in their regulation through other pathways may also be an important step in the pathogenesis of acute leukemias. Recent studies have shown that overexpression of the inactive forms of caspases CPP32 (caspase 3) and ICH-1 (caspase 2) is frequently observed in the blasts of patients with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL). Many other enzymes involved in apoptosis are expressed at high levels in patients with acute leukemia. Whether this signals the capacity of leukemic cells to rapid induction of apoptosis with fast reduction of the burden of disease and favorable clinical outcome, or accumulation of inactive substrates that cannot be activated by lack of cellular mechanisms to do so, requires further investigation. With the identification of many other regulators of apoptotic activity in the leukemic cells, new targets for future therapy may be identified and many new insights can be gained in understanding the biological behavior of response and resistance to therapy as well as control and relapse from minimal residual disease.
[Quality of life of hemodialysis patients in a Brazilian Public Hospital in Belém - Pará].

INTRODUCTION End-stage chronic kidney disease (CKD) requiring dialysis affects the quality of life sometimes more severely than other chronic diseases, such as rheumatoid arthritis, heart failure, coronary artery disease, and chronic obstructive pulmonary disease, exerting a negative effect on the energy and vitality levels, limiting social interactions, and hindering psychic health. OBJECTIVE To evaluate the quality of life of patients with CKD on hemodialysis in a public Brazilian Amazonian hospital. METHODS Data were collected through interview based on the Brazilian version of the SF-36 questionnaire. The study was conducted on 50 patients (mean age, 48 ± 16 years; mean hemodialysis time, 3 ± 2.9 years). RESULTS The most affected domain was role limitations due to physical health, with a mean score of 36 ± 36, and 58% of the patients in the lowest quartile, while mental health and social functioning were relatively preserved, with most patients in the highest quartile. Men obtained poorer scores than women did for role limitations due to physical health and vitality. Age correlated negatively with physical functioning. Patients on hemodialysis for more than one year had better scores in the social functioning domain, with a positive correlation between dialysis time and physical functioning. CONCLUSIONS The domains assessed were globally impaired in the population studied, especially regarding role limitations due to physical health, suggesting that chronic disease with prolonged treatment has a negative influence on those domains.
Acoustic Analysis of Snoring in the Diagnosis of Obstructive Sleep Apnea Syndrome: A Call for More Rigorous Studies.

BACKGROUND Snoring is a common symptom of obstructive sleep apnea syndrome (OSA) and has recently been considered for diagnosis of OSA. OBJECTIVES The goal of the current study was to systematically determine the accuracy of acoustic analysis of snoring in the diagnosis of OSA using a meta-analysis. METHODS PubMed, Cochrane Library database, and EMBASE were searched up to July 15, 2014. A systematic review and meta-analysis of sensitivity, specificity, and other measures of accuracy of acoustic analysis of snoring in the diagnosis of OSA were conducted. The median of apneahypopnea index threshold was 10 events/h, range: 5-15 or 10-15 if aforementioned suggestion is adopted. RESULTS A total of seven studies with 273 patients were included in the meta-analysis. The pooled estimates were as follows: sensitivity, 88% (95% confidence interval [CI]: 82-93%); specificity, 81% (95% CI: 72-88%); positive likelihood ratio (PLR), 4.44 (95% CI: 2.39-8.27); negative likelihood ratio (NLR), 0.15 (95% CI: 0.10-0.24); and diagnostic odds ratio (DOR), 32.18 (95% CI: 13.96-74.81). χ(2) values of sensitivity, specificity, PLR, NLR, and DOR were 2.37, 10.39, 12.57, 3.79, and 6.91 respectively (All p > 0.05). The area under the summary receiver operating characteristic curve was 0.93. Sensitivity analysis demonstrated that the pooled estimates were stable and reliable. The results of publication bias were not significant (p = 0.30). CONCLUSIONS Acoustic analysis of snoring is a relatively accurate but not a strong method for diagnosing OSA. There is an urgent need for rigorous studies involving large samples and single snore event tests with an efficacy criterion that reflects the particular features of snoring acoustics for OSA diagnosis.
