Published: November 2018

Abstract
Fungi and bacteria are encountered in many habitats where they live in complex communities interacting with one another mainly by producing secondary metabolites, which are organic compounds that are not directly involved in the normal growth, development, or reproduction of the organism. These organisms appear as a promising source for the discovery of novel bioactive natural products that may find their application in medicine. However, the production of secondary metabolites by those organisms when cultured axenically is limited as only a subset of biosynthetic genes is expressed under standard laboratory conditions leading to the search of new methods for the activation of the silent genes including epigenetic modification and co-cultivation. Biosynthetic gene clusters which produce secondary metabolites are known to be present in a heterochromatin state in which the transcription of constitutive genes is usually regulated by epigenetic modification including DNA methylation and histone deacetylation. Therefore, small-molecule epigenetic modifiers which promote changes in the structure of chromatin could control the expression of silent genes and may be rationally employed for the discovery of novel bioactive compounds. Co-cultivation, which is also known as mixed-fermentation, usually implies two or more microorganisms in the same medium in which the resulting competition is known to enhance the production of constitutively present compounds and/or to lead to the induction of cryptic metabolites that were not detected in axenic cultures of the considered axenic microorganism. Genomic strategies could help to identify biosynthetic gene clusters in fungal genomes and link them to their products by the means of novel algorithms as well as integrative pan-genomic approaches. Despite that all these techniques are still in their infancy, they appear as promising sources for the discovery of new bioactive compounds. This chapter presents recent ecological techniques for the discovery of new secondary metabolites that might find application in medicine.
A Lonerganian-Bakhtinian novelization of inculturation
Authors: Orji Cyril 
Published: November 2018

AbstractI wish to correlate Bernard Lonergan’s functional specialty Communications with Mikhail Bakhtin’s notion of novelistic discourse with the goal of teasing out how the Bakhtinian notion of discourse furthers on-going reflection on inculturation. Theology as a highly differentiated and specialized reflection on religion bears fruit in the final stage (Communications) of theological reflection. This fruit – inculturation – can be explained using different constructs. This paper privileges the Bakhtinian construct in that it addresses “the life and behavior of discourse in a contradictory and multi-languaged world” in ways that Lonergan’s differentiated and specialized reflection on theology accounts for multiplicity of cultural traditions in an ever-changing world church.
Wolbachia Infection Associated with Increased Recombination inDrosophila
Authors: Singh Nadia D 
Published: November 2018

AbstractWolbachia is a maternally-transmitted endosymbiotic bacteria that infects a large diversity of arthropod and nematode hosts. Some strains of Wolbachia are parasitic, manipulating host reproduction to benefit themselves, while other strains of Wolbachia exhibit obligate or facultative mutualisms with their host. The effects of Wolbachia on its host are many, though primarily relate to host immune and reproductive function. Here we test the hypothesis that Wolbachia infection alters the frequency of homologous recombination during meiosis. We use D. melanogaster as a model system, and survey recombination in eight wild-derived Wolbachia-infected (strain wMel) and Wolbachia-uninfected strains, controlling for genotype. We measure recombination in two intervals of the genome. Our results indicate that Wolbachia infection is associated with increased recombination in one genomic interval and not the other. The effect of Wolbachia infection on recombination is thus heterogenous across the genome. Our data also indicate a reproductive benefit of Wolbachia infection; infected females show higher fecundity than their uninfected genotypic controls. Given the prevalence of Wolbachia infection in natural populations, our findings suggest that Wolbachia infection is likely to contribute to recombination rate and fecundity variation among individuals in nature.

Published: November 2018

BACKGROUND:
The Centers for Disease Control and Prevention (CDC) published the Core Elements of Hospital Antibiotic Stewardship Programs (ASPs), while the Choosing Wisely for Newborn Medicine Top 5 list identified antibiotic therapy as an area of overuse. We identify the baseline prevalence and makeup of newborn-specific ASPs and assess the variability of NICU antibiotic use rates (AURs).

METHODS:
Data were collected using a cross-sectional audit of Vermont Oxford Network members in February 2016. Unit measures were derived from the 7 domains of the CDC’s Core Elements of Hospital ASPs, including leadership commitment, accountability, drug expertise, action, tracking, reporting, and education. Patient-level measures included patient demographics, indications, and reasons for therapy. An AUR, defined as the number of infants who are on antibiotic therapy divided by the census that day, was calculated for each unit.

RESULTS:
Overall, 143 centers completed structured self-assessments. No center addressed all 7 core elements. Of the 7, only accountability (55%) and drug expertise (62%) had compliance &gt;50%. Centers audited 4127 infants for current antibiotic exposure. There were 725 infants who received antibiotics, for a hospital median AUR of 17% (interquartile range 10%–26%). Of the 412 patients on &gt;48 hours of antibiotics, only 26% (107 out of 412) had positive culture results.

CONCLUSIONS:
Significant gaps exist between CDC recommendations to improve antibiotic use and antibiotic practices during the newborn period. There is wide variation in point prevalence AURs. Three-quarters of infants who received antibiotics for &gt;48 hours did not have infections proven by using cultures.
PR-activity of Ukrainian universities in social networks
Authors: Bakhmetieva A. 
Published: November 2018

Scientific problem. The paper notes that the desire of Ukrainian universities to carry out PR-activities in social media is correlated with the tendencies of PR activity of European and American universities. However, the lack of specialists in digital communications (SMM) within the staff of universities makes it possible to characterize their activity in social media as being carried out without a clear definition of goals and using limited tools. Due to the lack of strategic planning, we observe low communication efficiency of using social media.
Novelty. The brand pages of Ukrainian universities in social networks are analyzed, quantitative characteristics and content topics are investigated. Recommendations are developed for improving the efficiency of communication and updating the style of content on the brand pages of universities in social networks.
Research methodology. The official accounts of Ukrainian classical and technical universities in social networks (Facebook, YouTube, Twitter and Instagram) are discovered and analyzed the statistics of these pages. Based on the statistical data and the method of observation, brand pages of universities in social networks are defined in which are active and promising for the promotion of the communication strategy of universities, and which social networks have lost popularity among target audiences. In addition, the analysis of the contents of Facebook brand pages is done. The basic statistics is graphically presented in four tables, which allow comparing the PR activity of the universities in social media.
Results. For the effectiveness of PR in social media, it is necessary to increase the activity of followers, to distribute different content in the information and comment on the publications. It is proved that the lack of strategic planning of communicative activity in social networks negatively affects the results of both large PR campaigns and the effectiveness of communications for informational support of university activities. The main shortcomings in creating the content of the university's PR services and the main trends in writing messages in the Facebook news are revealed.
The practical significance. The detailed study of the PR-practice of the universities makes it possible to develop recommendations for increasing the effectiveness of promote brand pages in social networks.

Os mixosporídios são parasitos celulares encontrados nos diversos órgãos dos peixes de água doce ou estuarinos. Este grupo é economicamente importante por ser causador de doenças em inúmeros peixes, incluindo aqueles de valor comercial. Kudoa é destaque neste grupo por causar mioliquefação pós-mortem no pescado tornando-os impróprios para o consumo humano e, por isso, o conhecimento acerca deste gênero é de extrema importância. O objetivo deste trabalho foi descrever e caracterizar morfologicamente ogênero Kudoa Meglitsch, 1947 encontrado na musculatura esquelética em Genyatremus luteus. Foram coletados 22 espécimes de Genyatremus luteus, no município de São Caetano de Odivelas, nordeste paraense. Após a captura, os animais foram acondicionados em sacos plásticos com aeração artificial e transportados vivos ao Laboratório de Pesquisa Carlos Azevedo (LPCA), na Universidade Federal Rural da Amazônia, onde foram mantidos em aquários. Os animais foram anestesiados, sacrificados e, posteriormente, necropsiados para avaliação em microscopia de luz (ML). Fragmentos de musculatura esquelética foram retirados e esporos isolados, tetracapsulados, com corpo quadrangular ou pseudoquadrangular, determinantes do gênero Kudoa foram encontrados. Estes fragmentos contendo parasitos foram colhidos e fixados, desidratados, diafanizados e impregnados em parafina liquida. Foi realizado corte histológico e coloração em H&E, permitindo evidenciar a formação cística no interior e entre as fibras musculares. Estudos complementares estão sendo realizados para identificação da espécie encontrada, a fim de aumentar o conhecimento sobre o estado de sanidade dos peixes da região Amazônica no estado do Pará.

Authors: Brostolin Marta Regina 
Published: November 2018

A infância caracteriza-se como uma categoria histórica e social. A estrutura da sociedade, as condições de vida e de inserção da criança em cada contexto social, econômico, político e cultural é que vão tecer as diferentes concepções de infância e as diversas formas de ser criança. A partir dessa perspectiva, o presente texto resultante de uma revisão de literatura, tem por objetivo refletir e discutir a trajetória, políticas públicas e legislação referentes ao atendimento à criança no percurso da história num primeiro cenário. No segundo trata a criança como um sujeito de direitos, protagonista e ator social que produz e reproduz cultura e, no terceiro cenário aborda a Base Nacional Comum Curricular da Educação Infantil fazendo uma breve contextualização do momento atual pelo qual a educação brasileira passa. Conclui-se que para além das políticas de educação infantil é importante pensar em outras políticas quando se trata do atendimento integral a criança e, aqui se inclui aspectos relacionados não só à educação, como também, à saúde, à cultura e à proteção, o que torna necessária a interlocução, com outras áreas dos serviços públicos e outras ações que não são específicas da educação.
Evaluasi Kinerja Bagan Kendali Fm Pada Proses Short-Run

Published: November 2018

<p><em>The manufacturing production process that is currently trend is short-run. Short-run process is a job shop and a just in-time. These causes the process parameters to be unknown due to unavailability of data and generally a small amount of product. The control chart is one of the control charts which designed for the short run. The procedure of the control chart follows the concept of succesive difference and under the assumption of the multivariate Normal distribution. The sensitivity level of a control chart is evaluated based on the average run length (ARL) value. In this study, the ARL value was calculated based on the shift simulation of the average vector by recording the first m-point out of the control limits. The average vector shift simulation of the target () is performed simultaneously with the properties of a positive shift (=+ δ). Variations of data size and many variables in this study were m = 20, 50 and p = 2, 4, 8, respectively. Each scheme (a combination of δ, m and p) is iterated 250,000 times. The simulation results show that for all schemes when both parameters are known ARL<sub>0 </sub>≈ 370. But, when parameters are unknown, ARL<sub>1</sub> turn to smaller. This conclusion also implied when the number of p and n are increased, it reduce the sensitivity of the control chart.</em></p>
Standalone Sand Control Failure: The Role of Wellbore and Near Wellbore Hydro-Thermo-Chemical Phenomenon on the Plugging and the Flow Performance Impairments of the Standalone Sand Screen

Abstract
Although several workflows have been developed over the years for the design of the optimal sand control solutions in thermal applications, numerous sand control failures still occur every year. This paper aims at assessing the failure mechanism of different sand control techniques and the factors contributing to the failure by analyzing different failed sand control screen samples recovered from thermal and non-thermal wells.
Several failed standalone screens have been studied, which were collected from various fields and operational conditions. The screens were first inspected visually, and then certain sections of screens/pipes were selected for more detailed study on the failure mechanism. The liners/screens were cut into sections to be studied through SEM-EDX, reflective light microscopy, X-ray micro CT scan and petrographic thin sections to better understand the localized plugging mechanism. Through the studies of several polished sections, a statistical variation of the plugging zone was found. Moreover, we further focused on the critical zones such as the inlet and outlet of the aperture and the zone adjacent to the formation to better investigate the plugging mechanism.
The study on wire wrap screen samples revealed significant plugging of the annular space between the base pipe and the screen. Extensive clay/fines buildup in the annular space led to full to partial clogging in some sections. The base pipe corrosion study reveals that the corrosion mechanism is highly flow dependent since the perforation on the base pipe was enlarged to an oval shape from the original circular shape with its larger axis pointing toward the flow direction. The size of the plugged zone was significantly higher in the outer diameter section where a mixture of the clay and corrosion byproducts plugged the near screen pore space and the screen aperture. Examined premium mesh screen samples showed that the plugging mechanism is highly sensitive to the mesh size and assembly process. The highest pore impairments were associated with mesh screens in which the mesh was directly wrapped around the base pipe causing a reduced annular gap for the flow toward the perforations. The investigation of slotted liner samples showed widest plugging zone in the slot entrance and the lowest on the slot wall. A distinct interplay of the clay and corrosion byproduct led to the adsorption of clay, forming a compacted layer over the slot wall.
This paper reviews the plugging mechanism of the standalone sand control screen obtained from the field to provide first-hand evidence of the plugging mechanism and provides explanations for some of the poor field performances. The results could help engineers to better understand the micro-scale mechanisms leading to sand control plugging.
Structural Reliability Study of OCTG Casing and Connections for Thermal Wells
Authors: Khan Mohammad Sayed , Hamilton Andrew 
Published: November 2018

Abstract
This paper describes a reliability based study of OCTG connections and casing for thermal wells. The fundamental principle of structural reliability analysis is being used to model the uncertainties associated with the load capacity of the casing as well as different installation and the operational loading conditions. These uncertainties influence the strength and performance of the thermal well casing structure. Traditional deterministic design factor cannot quantify the uncertainties associated with these variables. Statistical distributions of these variables obtained from different sources such as analysis, production and laboratory test data. Finding the proper statistical distribution of installation and operational load of the represented thermal well data is challenging since each well is unique. However, with the reliable dataset of statistical significance used to build a structural reliability model with reasonable accuracy. This model used for risk analysis as well as could predict the failure mode during the early design phase. The probability theory used in the assessment of structural reliability model. The reliability model concerns the aspects of probabilistic modeling of load (S) and strength/resistance (R) variables. The combined loading conditions and elastic-plastic materials models are outlined to represent the thermal well. Structural reliability analysis methods such as FORM/SORM and Monte Carlo simulation will be discussed to address the randomness of casing loading and OCTG property uncertainty originating from the parameters mentioned above.
Pollution and Sun Exposure: A Deleterious Synergy. Mechanisms and Opportunities for Skin Protection
Authors: Marrot Laurent 
Published: November 2018

Background:
Pollutants are diverse chemical entities, including gases such as
ozone and particulate matter PM. PM contains toxic chemicals such as polycyclic aromatic
hydrocarbons (PAHs). Some PAHs can induce strong oxidative stress under UVA exposure.
Pollution aggravates some skin diseases such as atopy or eczema, but epidemiological data
also pointed to a correlation with early occurrence of (photo)-aging markers.

Objective:
This paper aims at reviewing current literature dealing with dermatological effects
of pollution, either on in vitro models or using in vivo approaches (including humans).
It particularly focuses on the probable deleterious synergy between pollutants and sunlight.

Results:
An exhaustive analysis of literature suggests that skin may be impacted by external
stress through oxidation of some of its surface components. However, pollutants detected in
plasma may also be provided to deep skin by the circulation of the blood. Oxidative stress,
inflammation and metabolic impairments are among the most probable mechanisms of pollution-
derived dermatological hazards. Moreover these stresses should be amplified by the
deleterious synergy between pollution and sunlight. Some experiments from our lab identified
few PAHs inducing a huge toxic stress, at nanomolar concentrations, when exposed to
long UVA wavelengths. Prevention strategies should thus combine surface protection (long
UVA sunscreens, antioxidants) and enhanced skin tissue resistance through stimulation of
the natural antioxidation/detoxification pathway Nrf2.

Conclusion:
In people exposed to highly polluted environments, pollutants and sunlight
may synergistically damage skin, requiring a specific protection.
