Authors: Madhubala M. , Kasthuri C. , Shukul Mansi , Ali J. Mohamed 
Published: November 2018

Background: The use of heparin and aspirin in obstetric care has grown considerably since their introduction into clinical practice. Because of the physiological changes of pregnancy, the usage of heparin and optimal dosage of heparin remains uncertain. Here our institute designed low dose Unfractionated Heparin (5000 IU s/c daily) as thrombo Prophylaxis regimen. To study the outcome of low dose UFH (5000 IU sc /daily) + Low dose aspirin (75 mg oral per day) for thrombo prophylaxis in utero placental insufficiency, in patient with 2 or more abortions.Methods: This retrospective study was conducted in 135 patients with 2 or more abortions as obstetric history. Prophylactic low dose of UFH (5000 IU s/c daily) + LDA 75 mg oral was initiated. The Primary outcome is live birth, and secondary outcomes is Reduced incidence of early onset of gestational hypertension (HT), Intrauterine Growth Retardation (IUGR).Results: Out of 135 women 131 gave live birth, 2 had first trimester abortion and 2 had intrauterine death by 5 to 6 months. PIH was higher in patients with more than 30 years of age.Conclusions: In our Retrospective, data combination of low dose UFH (5000IU s/c) + LDA (75mg oral) is as safe as routine thrombo prophylaxis with good compliance.
Vaginal cuff dehiscence after total laparoscopic hysterectomy a case report and brief review of the literature
Authors: Kalogeropoulos Sotirios , Chronopoulou Elpiniki , Iliopoulos Evangelos , Decavalas Georgios 
Published: November 2018

Vaginal cuff dehiscence (VCD) is a serious complication of total laparoscopic hysterectomy (TLH) or trachelectomy with high morbidity, as it can potentially lead to evisceration/bowel ischemia and sepsis. Authors present a case report of vaginal cuff dehiscence after laparoscopic trachelectomy. The patient reported post-coital onset of symptoms. She presented with acute abdomen and required urgent surgical intervention. In this case surgical management was dictated by the clinical manifestation. However, authors argue that conservative management is also an option for some of these patients and the decision regarding the management plan should be personalized according to the clinical presentation and the patient’s expectations. Emphasis should be given to avoid early onset of sexual activity during the immediate recovery period. Compared to women who underwent an abdominal or vaginal hysterectomy, those who had a laparoscopic procedure have less post-operative pain, shorter recovery period and often they are advised to return early to their normal habits and their work place. It is expected that this group of patients feel well enough to resume sexual activity soon after their procedure. Therefore, our counselling is of paramount importance as it should be highlighted that sexual intercourse is possibly the most common triggering event for VCD which a serious complication with severe morbidity is. The resumption should, therefore, follow medical consultation and be individualized according to co-morbidities which could affect healing, intraoperative findings and evaluation of the whole recovery progress.

ESTIMATION OF SEISMIC WAVES PARAMETERS WITH APPLICATION OF A GENETIC ALGORITHM
Authors: Sultangaleev R. R. , Troyan V. N. 
Published: November 2018

A Genetic algorithm (GA) is a very important method for the solution of non-linear problems. The basic steps in GA are coding, selection, crossover, mutation and choice. Coding is a way of representing data in binary notation. The algorithm must determine the fitness of the individual models. This means that the binary information is decoded into the physical model parameters and the forward problem is solved. The resulting synthetic data is estimated, then compared with the actual observed data using the specific fitness criteria. The selection of pairs of the individual models for the reproduction is based on their fitness values. Models with the higher fitness values are more likely to get the selection than models with low fitness values. A crossover caused the exchange of some information between the paired models thereby generating new models. The mutation is a random change of binary state. The condition of the procedure of mutation: if a value obtained by a random number generator is less than a certain threshold value, the mutation procedure is performed. The last basic step in GA is choice. We choose from each pairs a model, which has the less fitness function. Then we produce the procedures: the crossover, the mutation and the choice. This procedure is continued until we obtain the optimal model. We have used the GA for the estimation of the velocity for the gradient layer. The synthetic seismogram was calculated by the finite- difference method. The obtained results showed a high effectiveness of GA for the seismic waves velocity estimation.

Acquiring Accurate Reservoir Data During TCP To Maximize Oil Production and Increase ESP Run Life

Published: November 2018

Abstract
Impulse testing using a simple drillstem testing (DST) or tubing-conveyed perforating (TCP) string is reinvigorated by employing a bidirectional wireless acoustic telemetry system. Paired with enhanced-functionality downhole test tools, the innovative approach reduces the cost of testing while providing critical data for completion design, reservoir monitoring and electric submersible pump (ESP) sizing.
Over 46% of all the reported premature pump failures today are associated with incorrect equipment selection and pump sizing. It is mainly due to a lack of reliable reservoir information and especially in new wells without any historical production data (Vandevier, 2010).Operating the pump outside its specified range due to incorrect sizing can cause either a severe downthrust or upthrust condition that results in premature wear of the pump stages and reduces the expected life. It is mainly associated with incorrect pump sizing due to a lack of reliable reservoir information. The oil industry has long sought improvements in performing reservoir characterisation and acquiring dynamic reservoir and well data necessary for ESP sizing, especially in new wells without historical production data. The proposed new methodology and a unique impulse testing technique allow acquiring reservoir data for proper pump sizing.
The impulse testing is not a new concept that allows testing the wells using a simple DST or TCP strings with no flow of hydrocarbon at the surface. This allows the cost to be reduced in comparison with conventional DST operations or any other testing methods.
A new impulse testing technique uses bi-directional wireless acoustic telemetry system to acquire real-time bottom hole pressure data and interface with remote-controllable new-generation downhole tools, such as a tester valve, circulating valve, firing head, or fluid sampler, to issue commands and verify tool status. The acquired data credibly represent reservoir pressure, fluid properties, and well inflow performance that can be used for proper pump sizing.
Pressure-Transient Behaviors of Wells in Fractured Reservoirs With Natural- and Hydraulic-Fracture Networks
Authors: Chen Zhiming , Liao Xinwei , Yu Wei , Sepehrnoori Kamy 
Published: November 2018

Summary
Fracture networks are extremely important for the management of groundwater, carbon sequestration, and petroleum resources in fractured reservoirs. Numerous efforts have been made to investigate transient behaviors with fracture networks. Unfortunately, because of the complexity and the arbitrary nature of fracture networks, it is still a challenge to study transient behaviors in a computationally efficient manner. In this work, we present a mesh-free approach to investigate transient behaviors in fractured media with complex fracture networks. Contributions of properties and geometries of fracture networks to the transient behaviors were systematically analyzed. The major findings are noted: There are approximately eight transient behaviors in fractured porous media with complex fracture networks. Each behavior has its own special features, which can be used to estimate the fluid front and quantify fracture properties. Geometries of fracture networks have important impacts on the occurrence and the duration of some transient behaviors, which provide a tool to identify the fracture geometries. The fluid production in the fractured porous media is improved with high-conductivity (denser, larger) and high-complexity fracture networks.

Authors: Chauhan Anjali , Sillu Devendra , Agnihotri Shekhar 
Published: November 2018

Background:
The limitless presence of pharmaceutical contaminants in discharged wastewater has
emerged as a threat to aquatic species and humans. Their presence in drinking water has although raised substantial
concerns, very little is known about the fate and ecological impacts of these pollutants. As a result, these pollutants
are inevitably introduced to our food chain at trace concentrations. Unfortunately, the conventional wastewater
treatment techniques are unable to treat pharmaceuticals completely with practical limitations. The focus has now
been shifted towards nanotechnology for the successful remediation of these persistent pollutants. Thus, the current
review specifically focuses on providing readers brief yet sharp insights into applications of various nanomaterials
for the removal of pharmaceutical contaminants.

Methods:
An exhaustive collection of bibliographic database was done with articles having high impact and citations
in relevant research domains. An in-depth analysis of screened papers was done through standard tools. Studies were
categorized according to the use of nanoscale materials as nano-adsorbents (graphene, carbon nanotubes), nanophotocatalysts
(metal, metal oxide), nano-filtration, and ozonation for promising alternative technologies for the
efficient removal of recalcitrant contaminants.

Results:
A total of 365 research articles were selected. The contemporary advancements in the field of nanomaterials
for drinking and wastewater treatment have been thoroughly analyzed along with their future perspectives.

Conclusion:
The recommendations provided in this article will be useful to adopt novel strategies for on-site removal
of the emerging contaminants in pharmaceutical effluents and related industries.

Published: November 2018

Background:Long suspected as transcriptional noise, recently recognized, long non-coding RNAs (lncRNAs) are emerging as an indicator, biomarker and therapy target in the physiologic and pathologic process. Mesenchymal stem cells and embryonic stem cells are important source for normal and therapeutic tissue repair. However, the mechanism of stem cell differentiation is not completely understood. Research on lncRNAs may provide novel insights into the mechanism of differentiation process of the stem cell which is important for the application of stem cell therapy. The lncRNAs field is still very young, new insights into lncRNAs function are emerging to a greater understanding of biological processes.Objective:In this review, we summarize the recent researches studying lncRNAs and illustrate how they act in the differentiation of the mesenchymal stem cells and embryonic stem cells, and discuss some future directions in this field.Results:Numerous lncRNAs were differentially expressed during differentiation of mesenchymal stem cells and embryonic stem cells. LncRNAs were able to regulate the differentiation processes through epigenetic regulation, transcription regulation and post-transcription regulation.Conclusion:LncRNAs are involved in the differentiation process of mesenchymal stem cells and embryonic stem cells, and they could become promising indicator, biomarker and therapeutic targets in the physiologic and pathologic process. However, the mechanisms of the role of lncRNAs still require further investigation.

Published: November 2018

Background:The provision of universal health coverage is acknowledged as a priority goal for healthcare systems globally. In South Africa, the National Health Insurance system has been endorsed as a funding model for the provision of universal health coverage for South Africans. Community Health Workers have contributed to better universal health coverage outcomes in many countries. A study in India revealed that coverage of health care practices is positively correlated with the knowledge level of Community Health Workers. In South Africa, there is a difference in the duration of training of Community Health Workers in different provinces, especially in Vhembe District.Objective:This study aimed to assess Community Health Workers’ knowledge regarding their roles and describe their challenges within the context of National Health Insurance.Methods:Qualitative design was used to collect data from 33 participants who formed five focus groups comprising six to eight members each. Ethical principles of research such as permission, informed consent, voluntary participation and anonymity were observed. Data was analysed using thematic data analysis technique guided by Tesch open coding method.Results:The findings revealed that Community Health Workers lack adequate knowledge regarding the roles they are expected to play within Ward Based Outreach teams. Some of the challenges they face include transportation to clients’ homes and poor reception in households.Conclusion:A review of the South African Qualification Authority health promoter unit standards is recommended coupled with the mentorship of Community Health Workers by retired nurses to help them understand their roles better.
MiRNAs: Biology, Biogenesis, their Web-based Tools, and Databases
Authors: Tafrihi Majid , Hasheminasab Elham 
Published: November 2018

Introduction: MicroRNAs (miRNAs), which are evolutionarily conserved, and endogenous non-coding RNAs, participate in the post-transcriptional regulation of eukaryotic genes. The biogenesis of miRNAs occurs in the nucleus. Then, in the cytoplasm, they are assembled along with some proteins in a ribonucleoprotein complex called RISC. miRNA component of the RISC complex binds to the complementary sequence of mRNA target depending on the degree of complementarity, and leads to mRNA degradation and/or inhibition of protein synthesis. miRNAs have been found in eukaryotes and some viruses play a role in development, metabolism, cell proliferation, growth, differentiation, and death.Objective:A large number of miRNAs and their targets were identified by different experimental techniques and computational approaches. The principal aim of this paper is to gather information about some miRNA databases and web-based tools for better and quicker access to relevant data.Results:Accordingly, in this paper, we collected and introduced miRNA databases and some webbased tools that have been developed by various research groups. We have categorized them into different classes including databases for viral miRNAs, and plant miRNAs, miRNAs in human beings, mice and other vertebrates, miRNAs related to human diseases, and target prediction, and miRNA expression. Also, we have presented relevant statistical information about these databases.

Destacando a questão da apropriação dos mecanismos culturais em
situação de 'exclusão" nas favelas do Brasil, o artigo aponta para a
emergência de uma literatura "marginal" no país e para a dominação da
linguagem escrita nos segmentos sociais que foram, por séculos,
excluídos por sua "iliteralidade". A autora associa a questão da natureza
do espetáculo aos ataques palestinos ocorridos, nos últimos trinta anos, e
analisados a partir do arquivo da BBC. O ponto de partida é o 11 de
setembro, evento que expressa o domínio sobre a arte da representação e
é expressão máxima da guerrilha de controle dos espetáculos midiáticos.
Essas diferentes experiências de controle da representação têm um
aspecto comum: a violência com que são representadas, fazendo das
convenções do espetáculo cinematográfico e da mídia espetáculos do 49
terror. Nesse sentido, ocupam lugares chaves no mundo contemporâneo,
a começar pelo próprio controle sobre os mecanismos de construção da
representação.

A obrigatoriedade do diploma e a identidade jornalística no Brasil: um olhar pelas margens
Authors: Albuquerque Afonso de 
Published: November 2018

O artigo investiga o problema da delimitação das fronteiras que definem a prática legitima do jornalismo, tendo por referência a obra de Barbie Zelizer. Destaca, a este respeito, a sua proposição de que o profissionalismo se desenvolveu de forma
incipiente no jornalismo e que a identidade jornalística é construída com base em narrativas compartilhadas, através das quais os jornalistas se constituem como uma comunidade interpretativa autorizada. Visto que o modelo de Zelizer foi elaborado tendo por referência o jornalismo americano, é preciso verificar a sua aplicabilidade ao jornalismo de outros países. O artigo faz isso em duas etapas. Na primeira,
considera, de modo comparativo, o desenvolvimento do profissionalismo no jornalismo em diferentes países da Europa Ocidental. Na segunda, discute o impacto que o
decreto-lei n° 972 de 17 de outubro de 1969, que regulamentou a profissão de jornalismo no Brasil, sobre o processo de construção de identidade dos jornalistas
do país.
