CONCEPTUAL MODEL OF THE EDUCATIONAL PRESUMPTIONS OF THE COORDINATION OF COLLABORATION AND COMPETITION CAPABILITIES IN DANCESPORT
Authors: Armas Audrius , Šniras Šarūnas
Published: April 2019

Background. Simultaneously manifested collaboration and competition capabilities are coordinated. This harmony is determined by social interdependency of participants of the activity. It is also true about the dancesport activity. Dancesport dancers mostly compete for higher results, but collaboration is obligatory in order to achieve that result. The problem question was what the educational presumptions of the coordination of collaboration and competition in the dancesport activity are. The research aim was to create the conceptual model of the educational presumptions of the coordination of collaboration and competition in the dancesport activity.

Research method was theoretical analysis and synthesis. The results of theoretical analysis are generalized and incorporated into the conceptual model.

Discussion and conclusions. The theoretical model of the educational presumptions of the coordination of collaboration and competition in dancesport compiled and presented on the basis of the analysis of scientific literature reveals the conceptual basis of the educational presumptions of the coordination of collaboration and competition in dancesport. Dancesport dancers act and strive for sport and personal goals by using collaboration and competition capabilities, coordinating them and reaching the higher form of coopetition (harmony). The model of the educational presumptions of the coordination of collaboration and competition in dancesport is based on the analysis of literature about the forms of the interpersonal interaction both in the social environment and sport activity, manifestation of discussed forms of the interaction and theory of empiric learning including capabilities.
LIFESTYLE PERCEPTIONS AMONG MIDDLE – AGED OBESE WOMEN
Authors: Vasiliauskaitė Živilė , Karanauskienė Diana
Published: April 2019

Background. The aim of the study was to establish the perceptions of lifestyles among middle-aged obese
women.
Methods. Data collection method was semi-structured face-to-face interview. Interview guide was based on
short form 36 (SF-36), long form of IPAQ and previous research (Bukman et al., 2014).
Results. All obese women of our study feel inferiority complex due to their physical appearance, feel dissatisfied
with themselves trying to hide their appearance, discomfort, and disadvantages. They have a lot of health problems:
joint pain, increased cholesterol level, increased blood pressure, heart beat rate, dyspnoea, as well as chronic diseases
such as type 2 diabetes, thyroid gland dysfunction and sleep disorders. All the subjects both had poor eating habits
and ate inadequate food. Some of the participants ate a lot before bedtime and skip breakfast. The physical activity
is limited and reduced of all subjects.
Conclusions. The relationship between excess weight and psychological well-being is complex, encompassing
physical, social and psychological factors. All obese women of our study feel inferiority complex due to their physical
appearance, dissatisfied with themselves. They complained of cardiovascular problems, sleep disorders and chronic
diseases. The physical activity was limited and decreased. Also, such a great weight excess caused a discomfort in
their daily life. Obese women in our study negatively view smoking effects, but they tolerate or even have positive
attitudes to alcohol consumption, though they acknowledge that alcohol increases their weight. Malnutrition is
most common problem of our respondents. They both had poor eating habits and ate inadequate food. Some of the
participants ate a lot before bedtime and skip breakfast. A lot of participants reported about their negative attitude to
their diet, but this attitude did not always act like a stimulus to change. Most of respondents could not find the time
or motivation to engage in the adequate physical activity. They wanted to increase their physical activity, but found
excuses not to do that – their excess of weight, lack of time, as well as laziness, passivity - the main causes of their
inactivity or poor physical activity.
MEMBANGUN SEMANGAT KERASULAN REMAJA KATOLIK DALAM KONTEKS MASYARAKAT PLURALIS DI INDONESIA
Authors: Supriyadi Agustinus
Published: April 2019

Catholic teens Indonesia is part of the Church in Indonesia and the Indonesian people. Indonesia consists of thousands of islands that stretched from Sabang to Merauke. This fact opens the possibility of a fairly wide occurrence of the encounter between cultures and simultaneous cross-cultural. This diversity is certainly a logical consequence to an enrichment of civilizations and diversity (plurality), although also contains elements of the loss. Plurality of Indonesian society on the one hand can make the Catholic teens swept away in the swift currents of the community to lose our identity or conflict. However Plurality can also awaken in the Catholic teen award nature between one race to the other races, between ethnic or tribal one with the other tribes, between groups with one another. In a pluralistic society such as this, the Catholic teens called to the apostolate. Through the act of self-discovery, live in love and have a sense of tolerance of differences is the real form of the apostolate.
KERASULAN AWAM DI BIDANG POLITIK (SOSIAL-KEMASYARAKATAN), DAN RELEVANSINYA BAGI MULTIKULTURALISME INDONESIA
Authors: Dewantara Agustinus Wisnu
Published: April 2019

The political responsibility is important, not because of the need for the love of the homeland and the challenge of the disintegration of the nation in multicultural sphere, but must be born of deep Christian faith. This paper specifically addresses to the lay apostolate in socio-politics-society. The Catholic laity was also called to be salt and light in the political world. The emergence of some form of practical theology (such as liberation theology and political theology) affirms that concern. The theme of the laity will be juxtaposed with a review of the "political attitude" voiced by the prophets in Scripture. The hope is that the laity will become more aware of its social-political calling as part of the faithful life to sound prophetic voice in the world. The struggle of the Church into a prophetic power largely depends on the laity (and of course in good cooperation with the priests). The laity today are called to be new prophets to proclaim the truth without becoming part of the defilement itself
Nonalcoholic Fatty Liver Disease: An Update on the Diagnosis
Authors: Zhang Jia-Zhen , Cai Jing-Jing , Yu Yao , She Zhi-Gang , Li Hongliang
Published: April 2019

Nonalcoholic fatty liver disease (NAFLD) is a common liver disease and a major cause of related complications such as cirrhosis and hepatocellular carcinoma (HCC). NAFLD progresses through the stages of simple steatosis, nonalcoholic steatohepatitis (NASH), fibrosis, cirrhosis, and
HCC. However, NAFLD usually cannot be diagnosed in a timely manner, which is largely attributed to the asymptomatic features of NAFLD patients and the lack of an effective and accurate noninvasive screening approach. Although liver biopsy has been recognized as a gold standard for diagnosing
NAFLD, this approach is not suitable for screening and monitoring NAFLD because of its high cost and invasiveness. Several noninvasive screening and diagnostic systemic assessments have been developed in recent years for NAFLD evaluation. Here we summarize the current status and methods for
NAFLD diagnosis, including both noninvasive (imaging, biomarkers) and invasive (liver biopsy) assessments. We further discuss the advantages and disadvantages of these developed diagnostic approaches for NAFLD.
Mechanochemical synthesis of poly(trimethylene carbonate)s: an example of rate acceleration
Authors: Park Sora , Kim Jeung Gon
Published: April 2019

Mechanochemical polymerization is a rapidly growing area and a number of polymeric materials can now be obtained through green mechanochemical synthesis. In addition to the general merits of mechanochemistry, such as being solvent-free and resulting in high conversions, we herein explore rate acceleration under ball-milling conditions while the conventional solution-state synthesis suffer from low reactivity. The solvent-free mechanochemical polymerization of trimethylene carbonate using the organocatalysts 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) and 1,5,7-triazabicyclo[4.4.0]dec-5-ene (TBD) are examined herein. The polymerizations under ball-milling conditions exhibited significant rate enhancements compared to polymerizations in solution. A number of milling parameters were evaluated for the ball-milling polymerization. Temperature increases due to ball collisions and exothermic energy output did not affect the polymerization rate significantly and the initial mixing speed was important for chain-length control. Liquid-assisted grinding was applied for the synthesis of high molecular weight polymers, but it failed to protect the polymer chain from mechanical degradation.
Factors Related to Insomnia in Adult Patients with Tinnitus and/or Hyperacusis: An Exploratory Analysis
Authors: Aazh Hashir , Baguley David M. , Moore Brian C. J.
Published: April 2019

Background:People with tinnitus and/or hyperacusis often experience insomnia. However, it is unclear what factors are most strongly associated with insomnia.Purpose:To explore factors related to insomnia in patients with tinnitus and/or hyperacusis.Research Design:This
was a retrospective study using multiple-regression analysis.Study Sample:Data were assessed for 444 consecutive patients who sought help concerning their tinnitus and/or hyperacusis from a specialist audiology center in the UK National Health Service. The average age of the patients
was 54 years (standard deviation = 15 years).Data Collection and Analysis:The results of audiological tests and self-report questionnaires were gathered retrospectively from the records of the patients. Multiple-regression analysis was used to assess the relationship between insomnia
and other variables.Results:Sixty-nine percent of patients with tinnitus experienced some form of insomnia as measured via the Insomnia Severity Index (ISI). A multiple-regression model showed that ISI scores were significantly associated with depression scores measured via the depression
subscale of the Hospital Anxiety and Depression Scale (HADS) (regression coefficient [b] = 0.44, p < 0.001), tinnitus annoyance measured via the visual analog scale (VAS) (b = 0.49, p = 0.001), anxiety measured via the anxiety subscale of the HADS (b =
0.21, p = 0.012), and tinnitus handicap measured via the Tinnitus Handicap Inventory (b = 0.07, p < 0.001). The model explained 45% of the variance in ISI scores. VAS scores for tinnitus loudness, hyperacusis-related measures, hearing thresholds, age, and gender were
not significantly related to insomnia.Conclusions:The prevalence of insomnia in patients with tinnitus is high. Both tinnitus-related factors and psychological factors are related to the severity of insomnia. Hyperacusis is not significantly associated with insomnia.
DYNAMICAL ANALYSIS TO EXPLAIN THE NUMERICAL ANOMALIES IN THE FAMILY OF ERMAKOV-KALITLIN TYPE METHODS
Authors: Cordero Alicia , Torregrosa Juan R. , Vindel Pura
Published: April 2019

In this paper, we study the dynamics of an iterative method based on the Ermakov-Kalitkin class of iterative schemes for solving nonlinear equations. As it was proven in ”A new family of iterative methods widening areas of convergence, Appl. Math. Comput.”, this family has the property of getting good estimations of the solution when Newton’s method fails. Moreover, the set of converging starting points for several non-polynomial test functions was plotted and they showed to be wider in the case of proposed methods than in Newton’s case, for small values of the parameter. Now, we make a complex dynamical analysis of this parametric class in order to justify the stability properties of this family.
Masers and Other Instabilities in a Weakly Magnetized Relativistic Plasma: Theory and the Astrophysical Relevance of the Maser
Authors: Gruzinov Andrei , Waxman Eli
Published: April 2019

A sufficient condition for maser instability in a weakly magnetized relativistic plasma with an isotropic particle distribution function is given. Maser growth rates and polarizations are computed starting from the exact dielectric permittivity tensor of a magnetized plasma. For very weak magnetic field, our results confirm the approximate validity of the “standard maser theory,” which is based on the Einstein coefficients method, with one significant exception. For inclined propagation and a realistic (small but finite) field, the growth rates of the two (nearly circular) polarizations differ significantly, while the standard theory predicts two (nearly circular) polarizations with similar growth rates. We show that this deviation is due to circularly polarized synchrotron emission, which is neglected in the standard theory. The maser is shown to grow slower than Langmuir waves. Nevertheless, significant generation of EM waves is seen in (highly simplified) direct numerical simulations. We study the nonlinear saturation of maser instability and find that it offers a mechanism for the conversion of a significant fraction of the plasma energy into radio waves. We briefly discuss the conditions under which maser instability may operate in astrophysical sources and provide rough estimates that may be used for guidance when studying particular astrophysical sources/phenomena.
Proton Temperature-anisotropy Instability Coexisting with Ambient Turbulence in the Solar-wind Plasma
Authors: Markovskii S. A. , Vasquez Bernard J. , Chandran Benjamin D. G.
Published: April 2019

The description of the thermal-ion instabilities in the solar wind is usually based on the assumption of a uniform and stationary background. However, the instabilities have to coexist with omnipresent turbulence that makes the ambient medium inhomogeneous and time dependent. We perform three-dimensional hybrid simulations with particle-in-cell protons and a quasi-neutralizing electron fluid to investigate the effect of the turbulence on a particular instability. The instability is driven by the proton temperature anisotropy and it would generate Alfvén/proton-cyclotron waves propagating nearly parallel to the mean magnetic field if the turbulence were not present. The turbulence in our simulations is approximately two-dimensional with wavevectors highly oblique to the magnetic field. We find that, first, the turbulence results in a considerable modification of the proton distribution function. This contributes to the properties of the instability, such as its growth rate and saturation level. Second, the spatial inhomogeneity associated with the turbulent fluctuations extends the spectrum of the unstable waves to higher perpendicular wavenumbers making them more oblique. This is similar to the effect exerted on an instability by a static nonuniform background. Despite the quantitative changes introduced by the turbulence, we conclude that the instability remains qualitatively the same.
Binary Red Supergiants. II. Discovering and Characterizing B-type Companions
Authors: Neugent Kathryn F. , Levesque Emily M. , Massey Philip , Morrell Nidia I.
Published: April 2019

The percentage of massive main-sequence OB stars in binary systems is thought to be as high as 100%. However, very few Galactic binary red supergiants (RSGs) have been identified, despite the fact that these stars are the evolved descendants of OB stars. As shown in our recent paper, binary RSGs will likely have B-type companions, as dictated by stellar evolution considerations. Such a system will have a very unique photometric signature due to the shape of the spectral energy distribution. Using photometric cutoffs, it should therefore be possible to detect candidate RSG+B star binary systems. Here we present our spectroscopic follow-up observations of such candidates. Out of our initial list of 280 candidates in M31 and M33, we observed 149 and confirmed 63 as newly discovered RSG+B star binary systems. Additional spectra of four candidate systems in the Small Magellanic Cloud confirmed all of them as new RSG+B star binaries including the first known RSG+Be star system. By fitting BSTAR06 and MARCS model atmospheres to the newly obtained spectra, we place estimates on the temperatures and subtypes of both the B stars and RSGs. Overall, we have found 87 new RSG+B star binary systems in M31, M33 and the Small and Large Magellanic Clouds. Our future studies are aimed at determining the binary fraction of RSGs.

Published: April 2019

Azorean volcanic cave biodiversity is under considerable pressure due to ongoing threats of pollution, land use change, touristic activities or climate change. In this contribution, we present the IUCN Red List profiles of 15 cave-adapted arthropod species, endemic to the Azorean archipelago, including species belonging to the speciose genus Trechus (Carabidae), which is represented in Azores by seven species. The objective of this paper is to assess all endemic Azorean cave-adapted species and advise on possible future research and conservation actions critical for the long-term survival of the most endangered species.

Most species have a restricted distribution (i.e. occur in one or two caves), very small extent of occurrence (EOO) and a small area of occupancy (AOO). A continuing decline in the number of mature individuals is inferred from the ongoing cave habitat degradation. The two troglobitic species of the homopteran genus Cixius are in great danger of extinction due to major land-use changes in epigean habitats above their known localities. We suggest, as future measures of conservation, the regular monitoring of the species (every five years), the creation of additional protected caves, the limitation of several aggressive activities around the caves (e.g. decreasing pasture intensification) and in some cases the creation of fences in the entrance of the most important caves.
Review of the fish parasitic genus Elthusa Schioedte & Meinert, 1884 (Crustacea, Isopoda, Cymothoidae) from South Africa, including the description of three new species
Authors: van der Wal Serita , Smit Nico J. , Hadfield Kerry A.
Published: April 2019

The branchial-attaching cymothoid genus, Elthusa Schioedte & Meinert, 1884 is a genus with a worldwide distribution of 36 species, including the three species described here. Elthusaraynaudii (Milne Edwards, 1840) is the only species that has been described from southern Africa. All South African material held at the National Museum of Natural History, Paris, France (MNHN) and the Iziko South African Museum, Cape Town (SAMC) identified as, or appearing to belong to, Elthusa was examined. Four species were identified, Elthusaraynaudii and three species that proved to be undescribed. Elthusaxenasp. n. can be distinguished by an evenly rounded pereonite 1 anterior margin, a roughly rectangular pleotelson, and narrowly rounded uropod apices that extend to more than half the length of the pleotelson. Elthusaacutinasasp. n. is identified by the produced and narrowly rounded cephalon anterior margin, acute uropods that are shorter than half the length of the pleotelson, and pereonite 1 anterior margin with medial projection. Elthusarotundasp. n. is characterised by the round body shape, broadly rounded uropod apices, and protrusions on the proximal and lateral margins of the merus and carpus of pereopod 7. A key to the South African Elthusa species is provided, together with a table summarising the hosts and localities of the 33 previously known species of Elthusa.

Authors: Bousquet Franck
Published: April 2019

L’objectif de cet article est double : étudier les évolutions de l’information service et celles des titres de la Presse Quotidienne Régionale française. Ainsi, après un retour sur la notion d’information service et sur son rôle dans l’établissement de l’offre informationnelle, aussi bien éditoriale qu’économique, proposée par la PQR, il s’agira d’abord d’étudier ses reconfigurations socio-financières contemporaines ainsi que de présenter les acteurs médiatiques qui se proposent désormais de la prendre en charge. Par la suite, par l’intermédiaire de la mobilisation du concept de territoire nous tenterons de déterminer les nouvelles frontières que dessinent ces évolutions, pour les titres de la PQR mais aussi pour l’information infra-nationale en général.

Published: April 2019

We aimed at assessing the evidence for an effect on vaginal dysbiosis by oral administration of a mixture of Lactobacillus strains isolated from vaginal microbiota. For this purpose, we systematically reviewed the literature for randomised clinical trials (RCTs) in which the effect of oral administration of a mixture of four Lactobacillus strains (Lactobacillus crispatus LbV 88 (DSM 22566), Lactobacillus gasseri LbV 150N (DSM 22583), Lactobacillus jensenii LbV 116 (DSM 22567) and Lactobacillus rhamnosus LbV96 (DSM 22560)) on vaginal dysbiosis was examined based on Nugent score. Four RCTs were identified: a double-blind (DB)-RCT in 60 male-to-female transsexual women with neovagina; an open label RCT in 60 pregnant women with herpes virus infection; a DB-RCT in 36 women with bacterial vaginosis; a DB-RCT in 22 postmenopausal breast cancer patients receiving chemotherapy. Only in the three DB-RCTs Nugent score was assessed. The meta-analysis of these trials showed a significant reduction of Nugent score by probiotics compared to placebo in the fixed (standardised mean differences (SMD) -0.561; confidence interval (CI) -0.935 to -0.186; P=0.004 and random effect models (SMD -0.561; CI -0.935 to -0.186; P=0.004). The odds ratio (OR) of the cases presenting with improved Nugent score after probiotics compared to placebo treatment showed a significant effect in the fixed (OR=3.936; CI 1.702 to 9.100; P=0.001) and random effect model (OR=3.902; CI 1.681 to 9.059; P=0.001) Cochran’s Q and I2 statistics showed no heterogeneity. This meta-analysis indicates that the oral intake of the pertinent Lactobacillus strains improves the microbial pattern in vaginal dysbiosis.

Uses of Non-Thermal Treatment Technologies in Liquid Foodstuff
Authors: Yıkmış Seydi
Published: April 2019

Heat treatments are the most basic methods used to provide microbiological and enzymatic inactivation of food. However, the applied high temperature affects important parameters such as color, nutritional value, taste, and sensory characteristics of foods in the negative direction. Therefore, in recent years, producers and consumers have sought to obtain healthy food with little deviation in quality parameters, and new techniques of non-thermal emerged from this point. In this chapter, non-thermal food such as accented electric fields, ultrasonic waves, high-pressure application, microfiltration, X-rays, ionizing radiation, high voltage electrical discharge, pulsed light, ultrasound, magnetic field heating, and information on conservation methods are given.

Assessing the Environmental Characteristics of the Margaret River Wine Region, Australia
Authors: Lacorde Mathieu
Published: April 2019

Six sub-regions of the Margaret River Geographical Indication were proposed in 1999 in an attempt to characterize local variations in grape-growing conditions. Detailed environmental data has since been produced and this article aims at reassessing the proposed sub-regions by means of a GIS-based spatial analysis of the new datasets. Topography, climate, and a variety of soil parameters were reviewed, and a relevant set submitted to an unsupervised isocluster classification to determine the natural clustering of environmental parameters. The analysis shows that the initial sub-regions do not consistently respect climate patterns and soil type distribution. It is proposed to distinguish twelve natural units by considering temperature and rainfall gradients as well as the presence of the Dunsborough Fault system which appears to have a significant control on soil distribution. This study also shows that average growing season temperatures have gained +0.2°C across the peninsula from 1961–2000 to 2001–2015.

Published: April 2019

Personalized medicare systems is an emerging field of research, which bears the potential to significantly reduce healthcare expenditures and treatment errors and thereby to revolutionize the entire treatment procedure. In this novel approach, genomic variation in different individuals is duly taken into consideration. However, there exist several serious issues (e.g. privacy concerns) that provide hindrance to large-scale adoption of this medicare system. The main objective of this study has been to identify the privacy issues and to evaluate their impact on successful implementation of this novel medical treatment. The methodology used is empirical and is based on a survey-based post facto procedure. The data collected from the survey are analyzed by using the method of structural modelling analysis. This is an original study in the realm of healthcare management, which reveals that the technology related factors and privacy concerns have considerable impact on the successful implementation of personalized medicare system on a large scale. But the privacy concerns have no significant moderating effect on the impact of technology related factors, so far, the success of implementation of personalized medicine is concerned.

Pre-Marital Counselling and Sustainability of Marriages in Contemporary Ghanaian Society
Authors: Cobbinah Joseph Ezale , Osei-Tutu Ellen Mabel
Published: April 2019

Marriages in Ghana are usually preceded by counseling. It is believed that premarital counseling helps to sustain marriages because it gives couples the initial skills needed to enable them to start their marriage and solve minor problems that may be encountered in the relationship. This study was aimed at assessing the significance of premarital counseling to the sustenance of marriage. The study adopted a mixed methodological approach in gathering the data. Data was gathered from 112 individuals from three different suburbs of the capital city of Ghana. The results showed that although pre-marital counseling was observed to be important for would-be couples, it does not help sustain all marriages. Married couples that were given pre-marital counseling were getting separated as well as those who never had pre-marital counseling. It is therefore recommended that although premarital counseling may be necessary, it is not sufficient to sustain marriages. Therefore, counseling should continue even after marriage.
An Observational Study of Leadership Dysfunction in Nonprofit Governance
Authors: Kayal Sr. Raymond John
Published: April 2019

This case study shows how observational research explained behaviors in the volunteer board of directors of the Good Sisters of Guardian Angels, a faith-based community service organization. This article presents a review of the literature and experiential information relating to human and organizational behavior and boardroom best practices. The study shows how the mix of status and personality characteristics with opposing motivational forces resulted in boardroom balkanization and high turnover. In response to the research questions, personal observation, notes, communications, and public records were used to gather the data which were analyzed and compared inferentially for behaviors prejudicial to group harmony. This study used third-party participant observation to examine decision-making behavior in forming a model of reality and moral reasoning reflective of the ethical dilemmas faced by study participants. The findings suggest that greater care should be given to board member nominations to more closely align with the organization's mission.
Synergistic Effect of Micro and Nano Fillers on Mechanical and Thermal Behavior of Glass-Basalt Hybrid Nano Composites
Authors: Rudresh B M  , Ravikumar B N  , Madhu D  , Lingesh B V
Published: April 2019

This article deals with the combined effect of micro and nano fillers on mechanical, thermal and morphological behavior of glass-basalt hybrid composites (GB). Three material systems were selected for the study: glass-basalt fiber reinforced 80 wt. % PA66 – 20 wt. % PTFE blend (GB), GB/Micro fillers (MoS2, SiC, Al2O3) (GBM) and GBM/nano fillers (TiO2) (GBN). It has been revealed from the experimentation that the effect of micro fillers deteriorated the mechanical behavior of micro composites (GBM). But the combined effect of micro and nano fillers slightly impaired the mechanical behavior of nano composites. The synergistic effect of micro and nano fillers constrained the loss of strength of nano composites. But the impact strength of nano composites has been improved due to hybrid fillers effect. The hybrid effect of fillers significantly improved the thermal stability of nano composites. Further, it is observed from the morphology that the fractured surfaces were characterized by fiber pull out and fiber overlapping, severe deformation and agglomeration of nano particles.
Investigation Into Cloud Computing Adoption Within the Hedge Fund Industry

Published: April 2019

Cloud computing is not associated with a specific technology, instead it as an alternative method to deliver technology as a service. This article investigates current cloud computing adoption in the United States (USA) and United Kingdom (UK) hedge fund industry. Hedge fund technologists, prime service consultants, technology service providers, industry application vendors, investors and an independent information security consultant participated were surveyed for this article. The article acknowledges the growth of cloud computing in the hedge fund sector. This research work also highlights that the private cloud definition is vague and requires further classification, elaborating on the variants of private cloud. This is important as the variants of private cloud computing offer varying benefits and risk which the hedge fund sector has proven to be sensitive. Equally, this article argues that some of the current security concerns are over-stated and perhaps reflect a conservative decision making framework rather than a realistic consideration of the options.

Published: April 2019

The objective of this study was to evaluate the effect of marigold flower extract and paprika on egg quality of Black Avifran laying hens in different periods of storage. A completely randomized design study with a 3x3 factorial scheme with three diets (control, paprika, and marigold flower extract) and three storage periods (0, 7, and 14 days) was carried out. The following metrics were evaluated: egg weight, yolk weight, shell weight; yolk color, albumen height, specific gravity, and Haugh unit as well as the yolk, shell, and albumen percentage relative to the total weight of the egg. There was no significant interaction between additives and storage time (p > 0.05) for most of the parameters evaluated. The only exception was observed for yolk color, in which the interaction effect between treatments was significant (p < 0.05). The effect of storage time was significant (p < 0.05) for albumen weight, albumen percentage, yolk color, albumen height, specific gravity, and Haugh unit, with reduction of these parameters over the evaluation period. The use of paprika and marigold flower extract in the diets of Black Avifran laying hens does not influence egg quality.

Carcass and meat characteristics of 48 Nellore heifers at 24 to 30 months of age, with an initial weight of 263.4 ± 13.9 kg, were evaluated. The experiment was set up as a completely randomized design with four treatments, which consisted of four slaughter-weight classes, namely <340, 340-370, 370-400, or >400 kg. Back fat thickness was not influenced (p > 0.05) by slaughter weight in any of the forms it was expressed (mm or %), averaging 5.3 mm. Loin eye area in cm2 increased (p < 0.05) with the increase in slaughter weight. Animals slaughtered at a live weight (LW) of more than 400 kg showed better (p < 0.05) carcass conformation than the other experimental groups (9.8 points). Heifers slaughtered at over 400 kg LW had a more compact (p < 0.05) carcass (1.65 cm kg-1 cold carcass). The marbling degree of meat was lower (p < 0.05) in the animals slaughtered at less than 340 kg LW. In conclusion, cull heifers must not be slaughtered at a LW of less than 340 kg and slaughter weights greater than 400 kg have positive implications on important carcass characteristics, notably conformation and marbling.

The objective of this work was to evaluate the chemical composition and rumen disappearance rate of dry matter of corn silages with inoculants combining L. buchneri strain LN40177 in different strata of the silo. The experimental design was a 3x2 randomized complete block design, with three treatments: Control: corn silage without inoculant; 11CFT: corn silage with inoculant which combines L. buchneri strain LN40177 (1.1 x 1011 CFU g-1) with L. casei (1.1 x 1011 CFU g-1); and 11C33: corn silage with inoculant which combines L. buchneri strain LN40177 (1.1 x 1011 CFU g-1) with L. plantarum (1.1 x 1011 CFU g-1) and Enterococcus faecium (1 x 1010 CFU g-1), associated with two strata of the silo (lower and upper). The silage inoculated with 11C33 presented higher contents of crude protein and NDF and lower hemicellulose content in relation to the control treatment and 11CFT. The use of both inoculants resulted in silages with higher concentrations of soluble nutrients. Lower stratum silage had a higher rumen disappearance rate of dry matter compared to the upper stratum. In general, the combinations of L. buchneri promoted nutritional improvements in corn silage, but in presence of L. casei, there were more outstanding improvements.

The aim of this study was to evaluate the action of commercial and non-commercial cellulase and pectinase on rice husk and Tifton 85 hay hydrolyses. The hydrolysis kinetics of the substrates with commercial cellulase and pectinase were evaluated and the hydrolysis at different temperature and agitation conditions was maximized using experimental design. The combined use of commercial and non-commercial enzymes under optimized conditions was evaluated. The pre-treatment of the residues was also investigated by milling and different concentrations of NaOH. Finally, the effect of the hydrolysis on the bromatological composition of the residues was evaluated. The best hydrolysis times of rice husk and Tifton 85 hay were 10 and 12h for commercial cellulase, 12 and 14h for non-commercial cellulase, 10 and 14h for commercial pectinase and 16 and 20h for non-commercial pectinase, respectively. The highest hydrolysis values were obtained using commercial cellulase with 1:50 (w:v enzyme:water) dilution rate, at 45ºC and 300 rpm agitation for both substrates, reaching 20.6% maximum percentage for Tifton 85 hay and 11.6% for rice husk. The combined use of commercial enzymes did not increase hydrolysis percentage. The pre-treatment using 7.5% NaOH and 0.5 mm grain size significantly increased the rice husk and Tifton 85 hay hydrolyses (60-80%), either using commercial cellulase or pectinase enzymes. The use of non-commercial enzymes provided 18-30% hydrolysis obtained from commercial ones. Bromatological analyzes indicated a reduction in neutral detergent fiber and acid detergent fiber content for rice husk and Tifton 85 hay when using pectinases and commercial cellulases.
Antropofagia, sentimento íntimo e sincronicidade: uma possível introdução para a análise do humor na literatura brasileira
Authors: França Eduardo Melo
Published: April 2019

O objetivo deste trabalho é, a partir de uma reflexão sobre a fundação da literatura brasileira, no século XIX, e da relação que se estabeleceu desde então entre literatura e nação, propor uma problematização sobre a presença do humor – enquanto estrutura literária, elemento mimetizado e meio de reflexão – entre os autores que compõem a literatura brasileira. Para isso, admitindo a ideia machadiana de sentimento íntimo, recortes sincrônicos e uma perspectiva antropofágica, propomos investigar se é possível reconhecer nas obras nacionais, marcadas pelo humor, traços de um diálogo com (1) tradições literárias, autores e retóricas relacionadas ao humor, com (2) reflexões teóricas, psicológicas, filosóficas ou sociológicas sobre a origem, manifestação e efeitos decorrentes do humor e a (3) possibilidade dessa manifestação expressar algum traço característico de determinado período histórico ou cultura particular.
Fantástico e psicanálise: relações históricas e discursivas
Authors: Rabêlo Fabiano Chagas , Martins Karla Patrícia Holanda , Danziato Leonardo José Barreira
Published: April 2019

Esclarece-se os pressupostos de uma proposta de interlocução entre psicanálise e literatura fantástica por meio do mapeamento da rede de trocas que se estabeleceu entre esses dois campos ao longo dos últimos 140 anos. A partir do resgate das definições e cronologias do fantástico, desenha-se um quadro esquemático de suas diferentes fases e vertentes, ao mesmo tempo que se estabelece um paralelo com a história da psicanálise e alguns de seus fundamentos teóricos e éticos. Indica-se como elementos comuns mais relevantes: o tensionamento e a proximidade com o discurso científico e a tradição romântica, a ênfase na sexualidade e na divisão psíquica, a interrogação de uma racionalidade totalizante e a valorização de uma modulação estética da angústia e do fenômeno do estranho. Ao final, questiona-se o estado atual dessa relação, destacando-se algumas contribuições que a literatura fantástica pode oferecer à investigação clínica psicanalítica.

This study reports the biosynthesis of narrow range diameter silver nanoparticles at optimum conditions usingEucalyptus corymbiaas a reducing and stabilizing agent. Optimal conditions for biosynthesis of silver nanoparticles (AgNPs) were found to be; an extraction temperature of 90°C, pH of 5.7 a Silver Nitrate concentration of 1mM and AgNO3to plant extract ratio of 4:1. UV-Visible spectroscopy monitored the formation of colloidal AgNPs. The UV-Visible spectrum showed a peak around 425 nm corresponding to the Plasmon absorbance of the AgNPs. The size and shape characterization of the AgNPs was done using Transmission Electron Microscopy (TEM) techniques which revealed narrow range diameter (18-20 nm), almost monodispersed AgNPs, spherical in nature and with minimal agglomeration. Energy Dispersive X-ray (EDX) results showed the presence of two peaks at 3.0 and 3.15 keV in the silver region. The Fourier Transform Infrared-Spectra (FTIR) of the plant extract and the AgNPs gave rise to vibrational peaks at 3260 and 1634 wavenumbers which are due to the presence of OH and –C=C-functional groups respectively.

Authors: Sanchez Gustavo
Published: April 2019

The objective of the paper is to show how dynamic machine learning modeling can help drillers and operators validate signals from their sensors. Data and signal quality are a big problem in the industry when it comes to digitization. The method will show the importance of having a validation pipeline, and how it can help other algorithms make better decisions. Our approach uses statistical principles, machine learning and advanced analytics. The method is ISO 8000 compliant and can provide a framework in data management and data quality for companies to use. Depending on the application the accuracy of our method will vary. Results are anywhere in the 88% - 99% range of accuracy. The process has been validated by a major drilling contractor in signals ranging from blow out prevention, dynamic positioning systems, and tripping. The process can save upwards of 50% of time spent cleaning, mapping, and validating sensor signals. The end product allows the user to understand problems in the data collection system from the sensor all the way to the enterprise historian. It will also reduce false positives and false negative that are present in maintenance, optimization, and automation.
