Bearing incipient fault diagnosis based upon maximal spectral kurtosis TQWT and group sparsity total variation denoising approach
Authors: Li Qing , Liang Steven Y.
Published: May 2018

Localized faults in rolling bearing tend to result in periodic shocks and thus arouse periodic responses in the vibration signal. In this paper, a novel fault diagnosis method based on maximal spectral kurtosis tunable Q-factor wavelet transformation (TQWT) and group sparsity total variation denoising (GS-TVD) is proposed to address the issue of bearing incipient failure. Firstly, the range of Q-factor was pre-selected according to the spectral distribution of impulse component, and bearing vibration signal was transformed by the TQWT method. Then, the spectral kurtosis of each scale transform coefficients was calculated, and the optimal Q-factor and decomposition scale can be selected according to the kurtosis maximum principle. In order to remove the interference components and high-frequency noise from the reconstructed vibration signal generated by inverse TQWT, the GS-TVD approach is employed, thus the cyclic periodicity characteristic and transient impulses can be detected obviously. The two cases experimental results indicate that the proposed technique is more effective and applicable for bearing incipient fault diagnosis compared with traditional method.
Teager energy enhancement base on polar coordinates at angular domain and feature extraction of bearing’s early fault
Authors: Mei Jianmin , Chang Chun , Ren Gang
Published: May 2018

Unstable signal under variable rotation speed condition can expose bearing’s weak fault feature more obviously, a method of Teager energy enhancement base on polar coordinates at angular domain (TEEPAD) is proposed in this paper to analyze the unstable signal and extract single or concurrent fault of bearing’s early failure. Firstly, order analysis is selected to resample the unstable signal in time domain to stationary signal in angular domain, then Teager energy operator of stationary signal in angular domain is calculated and projected on the polar coordinates plane to enhance the fault feature. Analysis result of actual signal shows that single or concurrent fault feature of bearing’s early failure is effectively extracted by TEEPAD, and the other components having different periods or random noise are restrained synchronously.

Water quality deterioration of treated oilfield injection water in the water distribution system of the Jianghan oilfield
Authors: Li Ji , Wang Yaru , Li Shenglan , Fang Liping , Hou Guangcheng , Shi Baoyou
Published: May 2018

The deterioration of treated oilfield injection water quality in the distribution system has become a common issue that hinders the application of oilfield wastewater as a reusable source for oil production. Hereby, this work devotes to monitoring treated water parameters and the formation of pipe scales in the whole distribution system in Jianghan oilfield. Our results showed that the cause of water deterioration in the distribution system is due to the increased suspended solids. Coupon tests indicated that the rates of pipe corrosion and scale formation significantly increased, which was in line with our monitoring data. This further demonstrates that the deterioration of injection water leads to significant pipe corrosion and scale formation after the long distance transportation from effluent wastewater treatment plants to injection wells. The chemical composition of the collected pipe scale is consistent with that of suspended solids extracted from water samples. This indicates that the increased suspended solids in water are likely due to the contribution of pipe scale that can be on the walls of pipelines, consequently deteriorating the injection water quality. The findings of the present study show an important significance in understanding the mechanism of injection water deterioration in the distribution system.

Authors: Zeng Xu , Liu Jun , Zhao Jianfu
Published: May 2018

Catalytic wet oxidation of high concentration pharmaceutical wastewater with Fe3+ as catalyst was carried out in a batch reactor. Results showed that the degradation of pharmaceutical wastewater was enhanced significantly by Fe3+. The effects of reaction parameters, such as the catalyst dose, reaction temperature, time, and initial oxygen pressure, were discussed. The chemical oxygen demand (COD) removal increased with the increases of catalyst dose, temperature, time and oxygen supply. With the initial COD 34,000–35,000 mg/L, approximately 70% COD removal can be achieved under the conditions of catalyst 1.0 g and oxygen pressure 1.0 MPa at 250 °C after 60 min. The results of kinetic studies showed that two reaction steps existed in this oxidation process, which followed an apparent first-order rate law. This process provides an effective approach for the pretreatment of high concentration pharmaceutical wastewater.

Authors: Poudel Shiva Raj
Published: May 2018

The main objective of the study is to identify the major indicators of credit risk among the Nepali commercial banks. The study is conducted using the sample of 15 commercial banks operated in Nepali economy. One way Fixed Effect Model (FEM) of panel data analysis is used as a major tool of analysis. All the data for the study were obtained from the database of Nepal Rastra Bank for bank specific variables and database of World Bank for macroeconomic variables for the year 2002/03 to 2014/15. The credit risk among the commercial banks in Nepal was regressed on bank specific variables such as liquidity, capital adequacy ratio, bank size, and interest spread. Similarly, the effects of macro-economic variables such as GDP growth, rate of inflation and interbank interest rate were also examined along with bank specific variables in identifying credit risk in Nepali commercial banks. The study reveals that liquidity has the significant positive impact on credit risk in Nepali commercial banks. In contrast, capital adequacy ratio and interest spread have the significant negative impact on credit risk. The analysis further confirmed that bank size and interest spread both have no any clear direction of impact on credit risk. Moving towards the GDP growth, credit risk in Nepali commercial banks is negatively fluctuates with GDP growth, however, the statistics show the coefficients are insignificant at 5% level. Contrarily, Inter-bank interest rate has insignificant negative impact on credit risk in Nepali commercial banks.
A Short Message Service Intervention for Improving Infant Feeding Practices in Shanghai, China: Planning, Implementation, and Process Evaluation (Preprint)
Authors: Jiang Hong , Li Mu , Wen Li Ming , Baur Louise A , He Gengsheng , Ma Xiaoying , Qian Xu
Published: May 2018

BACKGROUND

Although mobile health (mHealth) has been widely applied in health care services, few studies have reported the detailed process of the development and implementation of text messaging (short message service, SMS) interventions.

OBJECTIVE

Our study aims to demonstrate the process and lessons learned from a community-based text messaging (SMS) intervention for improving infant feeding in Shanghai, China.

METHODS

The intervention included planning and development, implementation, and process evaluation. A 3-phase process was adopted during planning and development: (1) a formative study with expectant and new mothers to explore the barriers of appropriate infant feeding practices; (2) a baseline questionnaire survey to understand potential intervention approaches; and (3) development of the text message bank. The text messaging intervention was delivered via a computer-based platform. A message bank was established before the start of the intervention containing information on the benefits of breastfeeding, preparing for breastfeeding, early initiation of breastfeeding, timely introduction of complementary foods, and establishing appropriate feeding practices, etc. An expert advisory committee oversaw the content and quality of the message bank. Process evaluation was conducted through field records and qualitative interviews with participating mothers.

RESULTS

We found that the text messaging intervention was feasible and well received by mothers because of its easy and flexible access. The weekly based message frequency was thought to be appropriate, and the contents were anticipatory and trustworthy. Some mothers had high expectations for timely response to inquiries. Occasionally, the text messages were not delivered due to unstable telecommunication transmission. Mothers suggested that the messages could be more personalized.

CONCLUSIONS

This study demonstrates the feasibility and value of text messaging intervention in filling gaps in delivering health care services and promoting healthy infant feeding practices in settings where personal contact is limited.

Authors: Dur Onur , Rhoades Colleen , Ng Sally Man Suen , Elsayed Ragwa , van Mourik Reinier , Majmudar Maulik D.
Published: May 2018

BACKGROUND

Wearable and connected health devices along with the recent advances in mobile and cloud computing provide a continuous, convenient-to-patient and scalable way to collect personal health data remotely. The Wavelet Health Platform and the Wavelet Wristband have been developed to capture multiple physiological signals and to derive biometrics from these signals including resting heart rate, heart rate variability, and respiration rate.

OBJECTIVE

This study aims to evaluate the accuracy of the biometrics estimates and signal quality of the wristband.

METHODS

Measurements collected from 35 subjects using the Wavelet Wristband were compared with simultaneously recorded electrocardiogram and spirometry measurements.

RESULTS

The heart rate, heart rate variability (SDNN) and respiration rate estimates matched within 0.6 ± 0.9 bpm, 7 ± 10 ms and 1 ± 1 brpm mean absolute deviation of the reference measurements, respectively. The quality of the raw plethysmography signal collected by the wristband, as determined by the harmonic-to-noise ratio, was comparable to that obtained from measurements from a finger-clip plethysmography device.

CONCLUSIONS

The accuracy of the biometrics estimates and high signal quality indicate that the Wristband PPG device is suitable for performing pulse wave analysis and measuring vital signs.

Authors: Lattie Emily G , Kaiser Susan M , Alam Nameyeh , Tomasino Kathryn N , Sargent Elizabeth , Rubanovich Caryn Kseniya , Palac Hannah L , Mohr David C
Published: May 2018

BACKGROUND

The ability to successfully recruit participants for electronic health (eHealth) clinical trials is largely dependent on the use of efficient and effective recruitment strategies. Determining which types of recruitment strategies to use presents a challenge for many researchers.

OBJECTIVE

The aim of this study was to present an analysis of the time-efficiency and cost-effectiveness of recruitment strategies for eHealth clinical trials, and it describes a framework for cost-effective trial recruitment.

METHODS

Participants were recruited for one of 5 eHealth trials of interventions for common mental health conditions. A multipronged recruitment approach was used, including digital (eg, social media and Craigslist), research registry-based, print (eg, flyers and posters on public transportation), clinic-based (eg, a general internal medicine clinic within an academic medical center and a large nonprofit health care organization), a market research recruitment firm, and traditional media strategies (eg, newspaper and television coverage in response to press releases). The time costs and fees for each recruitment method were calculated, and the participant yield on recruitment costs was calculated by dividing the number of enrolled participants by the total cost for each method.

RESULTS

A total of 777 participants were enrolled across all trials. Digital recruitment strategies yielded the largest number of participants across the 5 clinical trials and represented 34.0% (264/777) of the total enrolled participants. Registry-based recruitment strategies were in second place by enrolling 28.0% (217/777) of the total enrolled participants across trials. Research registry-based recruitment had a relatively high conversion rate from potential participants who contacted our center for being screened to be enrolled, and it was also the most cost-effective for enrolling participants in this set of clinical trials with a total cost per person enrolled at US $8.99.

CONCLUSIONS

On the basis of these results, a framework is proposed for participant recruitment. To make decisions on initiating and maintaining different types of recruitment strategies, the resources available and requirements of the research study (or studies) need to be carefully examined.

Authors: Lozano-Ortega Greta , Waser Nathalie , Bensink Mark E , Goring Sarah , Bennett Heather , Block Geoffrey A , Chertow Glenn M , Trotman Marie-Louise , Cooper Kerry , Levy Adrian R , Belozeroff Vasily
Published: May 2018

Aim:
Randomized controlled trials (RCTs) with clinical outcomes are considered the gold standard for regulatory approval. However, by design they are only able to answer a small number of clinical questions. Other high-quality studies are required for clinical decision-making. The EVOLVE was the largest RCT, evaluating the effects of cinacalcet on clinical outcomes among adult patients receiving maintenance dialysis suffering from secondary hyperparathyroidism. While the EVOLVE trial did not reach its primary end point, imbalance in subjects’ age at randomization and discontinuation rates are two of the reasons that the lack of mortality benefit is in question. We undertook a systematic literature review and Bayesian meta-analysis combining randomized and observational studies on the estimated effects of the oral calcimimetic cinacalcet on clinical outcomes including all-cause mortality, cardiovascular-related mortality, hospitalization for cardiovascular events, fracture and parathyroidectomy among patients on maintenance dialysis.
Methods:
Data sources included MEDLINE, EMBASE and Cochrane Central Register of Controlled Trials databases. RCTs and observational studies were included. Data extraction was completed by two authors independently and in duplicate determined the methodological quality of the studies and extracted data.
Results:
Of 564 unique citations identified, 16 studies were included: six observational studies and ten RCTs. Four high-quality studies (two observational and two RCTs) were deemed suitable for meta-analysis. Results indicated a statistically significant reduction in the risk of death associated with cinacalcet (hazard ratio: 0.83; 95% credible interval: 0.78–0.89).
Conclusion:
The results of this meta-analysis indicate that treatment of secondary hyperparathyroidism with calcimimetic therapy may in fact reduce mortality among patients receiving maintenance dialysis. This finding provides justification for a well-designed and adequately powered randomized trial to definitively address the question.

Authors: Escobar-Castellanos1 Blanca , Sanhueza-Alvarado2 Olivia
Published: May 2018

El objetivo del artículo es describir los patrones del conocimiento en enfermería de Barbara Carper y su influencia en los diferentes contextos de la disciplina de enfermería, en la investigación, educación y práctica. Metodología: revisión de la literatura científica realizada en las bases de datos de Bvs-BIREME, SciELO y PubMed durante los años 2008 al 2015, seleccionando nueve artículos que emplearon el abordaje de patrones del conocimiento de Carper como criterio de inclusión, tanto en investigaciones cualitativas como cuantitativas. La necesidad de fundamentar el quehacer profesional de Enfermería ha permitido desarrollar aspectos propios de la misma a través de valores, estructuras, formas, comportamientos y patrones de conocimiento que sirvan como directrices para ejemplificar características y modos de pensar acerca de los fenómenos de estudio. Hablar de patrones de conocimiento en la disciplina es hacer referencia a Bárbara Carper, quien identificó cuatro patrones fundamentales. Estos patrones se distinguen según el tipo de significado lógico: el empírico hace referencia a la ciencia de enfermería; el estético al arte de enfermería; el personal al conocimiento de uno mismo y los otros, y el ético permite el desarrollo del conocimiento moral en enfermería. Se concluye que cada patrón del conocimiento de enfermería tiene dimensiones y elementos esenciales que permiten su comprensión; todos son indivisibles, se pueden emplear de forma individual, pero se integran como un todo cuando se desarrolla la práctica del cuidado.
OS COLÉGIOS JESUÍTICOS EUROPEUS E SUAS INFLUÊNCIAS NO TEATRO POPULAR DE JOSÉ DE ANCHIETA: A ARTE DE CONVENCER
Authors: Silveira Camila Nunes Duarte , Casimiro Ana Palmira Bittencourt Santos , Almeida Maria Cleidiana O. de
Published: May 2018

A prática teatral não era novidade para os primeiros jesuítas que vieram para o Brasil. Na Europa, desde a fundação da Ordem e dos primeiros colégios, os jesuítas faziam amplo uso dos recursos cênicos como parte constituinte do currículo de seus estudantes. As representações eram recursos para as práticas oratórias como forma de expor os conteúdos aprendidos, sendo também importante artifício das comemorações. Sua obrigatoriedade já se fazia presente nas Constituições da Companhia e perdurou no texto da Ratio Studiorum. No contexto da América Portuguesa, José de Anchieta fez amplo uso de seus conhecimentos em retórica, adquirido no Colégio das Artes, em Coimbra, para criar um teatro adaptado ao seu público, formado principalmente por indígenas. Neste sentido, o presente estudo teve por objetivo analisar tal prática teatral nos Colégios Jesuíticos, especialmente no Colégio das Artes, em Coimbra, com vistas a identificar os elementos que subsidiaram José de Anchieta na criação de um teatro adaptado ao contexto da América Portuguesa. Os resultados apontaram que Anchieta não esqueceu seus estudos no colégio conimbricense, mas, pelo contrário, adaptou-os ao contexto do Novo Mundo, e soube aplicá-los à conjuntura social de acordo com as finalidades de catequização pensadas pelos jesuítas.
Income Shifting Using a Cost-Sharing Arrangement
Authors: De Simone Lisa , Sansing Richard C.
Published: May 2018

This study investigates the use of a cost-sharing arrangement (CSA) by a multinational corporation (MNC) to shift the income attributable to intangible property (IP) to low-tax foreign jurisdictions. We identify three major effects that determine whether an MNC will use a CSA to develop the IP rather than develop the IP domestically: an operating intangible effect, an undervaluation effect, and an enforcement effect. First, we find that the MNC is more likely to use a CSA to develop the IP when the MNC has valuable domestic operating intangibles, such as a global brand. Second, the MNC is more likely to use a CSA if the nature of the IP development project allows the MNC to understate the fair market value of the IP. Third, the MNC is less likely to use a CSA if the tax authority can cost effectively challenge the position and impose retroactive revaluations of the IP.

Synodal management in the Ukrainian Greek Catholic Church (18th–20th centuries)
Authors: Yasenitsky Vasiliy Matveyevich ,   Kolomna Theological Seminary
Published: May 2018

The study considers the history of synodal (conciliar) management in the Ukrainian Greek Catholic Church. The Zamość Council of 1720 became the first synod in the history of the Russian Uniate Church. In Galicia, such councils were not convened until 1891 while a synod with the participation of local bishops took place in Lviv. A great contribution to the revival and development of the Synodal Administration was made by Metropolitan Andrey (Sheptytsky) (1865–1944). Bishops’ Councils were constantly held under the guidance of the next head of the Ukrainian Greek Catholic Church Metropolitan Joseph Slepoy (1892–1984). The Synodal Administration was regulated in the Patriarchal Charter of 1973, which defined the highest ecclesiastical administration prior to the adoption of the Code of Canons of the Eastern Churches in 1990. The research analyzes the most important points of this document and describes the rules of the present-day particular law of the Ukrainian Greek Catholic Church regarding the structure and powers of the synod.
The initiation and development of the Federal Republic of Germany in the structure of the European cooperation in the 1950–1960s: a historiographical review
Authors: Barkalova Irina Nikolaevna ,   Donetsk Academy of Management and Public  Administration under the Head of the Donetsk People’s Republic
Published: May 2018

The study discusses the problematic historiography of the initiation and development of the Federal Republic of Germany in the structure of the European cooperation in the 1950–1960s. In the first instance, the analysis of economic and political factors of the European integration policy-making in Germany requires a consideration of the European Union as a unique phenomenon in world history. Since Germany is a country that dominates in the EU and its political forces and attitudes have a major impact on a Europe-wide policy, the European integration should be studied through the prism of determining the place and role of Germany in the pan-European structure. The backgrounds to the development of the European policy of the Federal Republic of Germany in the 1950–1960s are considered. For better and more comprehensive understanding of the subject matter, the author went beyond the period under study and tried to distract from the traditional German policy which for almost a thousand years had been predominantly aggressive.

Authors: Wantoro Wandi , Trihandaru Suryasatriya , Pattiserlihun Alvama
Published: May 2018

The measurements of gamma linear attenuation coefficient in the air at variance air pressure has been done. The measurements were performed to determine the effects of air pressure changes on gamma linear attenuation coefficient in the air. The measurements were used Co-60 as the gamma radiation source and LND 72 Geiger-Muller as the radiation detector in a room with 18oC room temperature and 68% air humidity. The linear attenuation coefficient value was calculated according to Lambert-Beer law. From the measurement, we obtained the attenuated gamma intensity in the air at air pressure variation. The unattenuated gamma intensity was determined by making a linear fit function of the attenuated gamma intensity data. From the calculation, It was found that the value of gamma linear attenuation coefficient in the air increases with the increasing of air pressure.

Published: May 2018

Sarcoidosis is a systemic disorder with unknown etiology and pathogenesis characterized by non-caseating granulomas, and different clinical manifestations of sarcoidosis hinder diagnosis and treatment. Therefore, a comprehensive understanding of serological markers based on clinical observations of sarcoidosis and the progression of granulomas would aid analysis in routine clinical practice. In this review, we overview common serological markers, including angiotensin converting enzyme (ACE) and lysozyme, and describe in detail new promising indices in sarcoidosis such as a T cell serological marker (soluble interleukin 2 receptor; sIL-2R) and thymus and activation-regulated chemokine (TARC/CCL17).

Dice Didi-Huberman en La imagen superviviente (2013) que, «cuando tratamos de saber si un cuerpo yacente está muerto o sobrevive, si posee todavía un residuo de energía animal, hay que estar atento a los movimientos» y bien cierto es que para que cualquier cuerpo, también el del arte, pueda afectar a otros, este debe ser capaz de moverse, y aún más, de moverse con un cierto ritmo.

The Effect of Amaranth Seeds, Sea Buckthorn Pomace and Black Chokeberry Pomace in Feed Mixtures for Broiler Chickens on Productive Performance, Carcass Characteristics and Selected Indicators of Meat Quality
Authors: Orczewska-Dudek Sylwia , Pietras Mariusz , Nowak Joanna
Published: May 2018

The aim of the present study was to determine the effect of amaranth seeds, dried sea buckthorn pomace and dried chokeberry pomace on the growth performance of broiler chickens and on the fatty acid profile and oxidative stability of meat lipids. The study was conducted on 480 Ross 308 chickens assigned in the second production phase to 4 experimental groups. The birds from the control group received 3% flax oil, while the chickens from the experimental groups were fed with mixtures containing: 3% flax oil and 8% amaranth seeds (group II), 3% flax oil and 3% dried sea buckthorn pomace (group III), and 3% flax oil and 3% dried chokeberry pomace (group IV). Basic production parameters were evaluated for each feeding period. At 42 days of age, 8 birds with body weight close to the average from each group were slaughtered. A simplified analysis of the chicken carcasses was conducted and samples of the breast muscles were collected for further analysis. The addition of 8% amaranth seeds into the feed mixtures in the second feeding phase decreased body weight gains (P<0.05) and increased the feed conversion ratio compared with groups receiving sea buckthorn or chokeberry pomace. However, the addition of amaranth seeds into the feed mixtures increased breast muscle yield (P<0.05) and decreased fat content in comparison to the other experimental groups. Moreover, sensory analysis of the breast muscles from chickens fed the diet with amaranth seeds revealed that they were characterised by a better aroma (P<0.05) and flavour. The studied feed additives did not significantly affect the physicochemical properties of the breast muscles. Sea buckthorn pomace efficiently slowed down lipid oxidation in the breast muscles. The obtained results indicate that using tested plant additives in feed mixture may be an effective way to improved production parameters of broiler chicken and effectively enriched meat in n-3 fatty acid and protect against excessive oxidation of lipids.
New Polymorphic Changes in the Wnt7A Gene and Their Effect on Reproductive Traits in Pigs

For many years, research has been undertaken to identify genetic markers associated with reproductive traits in pigs, but these issues are still open to research. WNT7A expression was found in endometrium during embryo implantation as well as in early pregnancy in humans and in different species of animals. Our study was designed to identify polymorphic changes in the WNT7A gene and their effect on reproductive traits in 480 Polish Large White (PLW ) and Polish Landrace (PL) pigs in 4 successive litters. As a result, 3 mutations were identified: two transitions in exon 3 g.6270G>A (rs326274214) and in intron 4 g.36251G>A (rs321204163) and deletion/insertion in intron 4 g.36220delinsAT (rs338143418). Frequency analysis of the genotypes of these polymorphisms in the WNT7A gene showed departure from Hardy-Weinberg equilibrium for PLW at locus g.36220delinsAT and for total breeds and PLW at locus g.36251G>A. Generally, the largest litters were found in sows with AA genotypes for mutations g.6270G>A and g.36251G>A and in sows with ins/ins genotype for mutation g.3622delinsAT . However, the sows of these genotypes formed only a small percentage (from 9% to 13%) in the studied group of animals. Statistical analysis showed significant differences only for the number of piglets born and reared in parity 1 (1NBA and 1N21d) in favor of the sows with genotype AA g.6270G>A (P≤0.05) and for the number of piglets born in litter 4 (4NBA) with genotype ins/ins g.3622delinsAT (P≤0.05). The analysed mutations had no effect on the age at first farrowing and the successive farrowing intervals.
The Influence of Plant Dominants on the Associated Species Abundance in Wet Tall-Herb Meadow Plant Communities
Authors: Lebedeva Vera , Tikhodeyeva Marina , Koptseva Elena
Published: May 2018

Plant interactions in wet tall-herb meadow plant communities were described through dominant and edificator species identification. Five dominant species were identified: Alopecurus pratensis, Filipendula ulmaria, Deschampsia cespitosa, Anthriscus sylvestris, and Angelica sylvestris. The effects of species were studied using ANOVA and correlation analyses. Not all dominants were recognised as edificators. Edificators (Alopecurus pratensis, Filipendula ulmaria, Deschampsia cespitosa, Angelica sylvestris) had a negative effect on the various abundance indicators of associated species: percent cover, number, phytomass, and height. The edificator effects differed significantly in their level and duration and depended on the biomorphs of dominants. The perennial species Alopecurus pratensis, Filipendula ulmaria, and Deschampsia cespitosa were strong constant edificators. Angelica sylvestris, a short-lived monocarpic from the Apiaceae, is a weak seasonal edificator, while Anthriscus sylvestris is not an edificator. Analysis of the life strategies of species showed that competitors are not always edificators (Anthriscus sylvestris), whereas stress-tolerant may show edificator properties (Deschampsia cespitosa). The associated plant species often show positive interactions. Most of the associated species are stress-tolerant and have not an edificator effect.
