Authors: Silva Maurina Dias da , Scareli-Santos Claudia 
Published: August 2019

O objetivou deste trabalho foi estudar a interação entre a planta hospedeira Ouratea spectabilis (Mart. Ex Engl.) Engl. (Ochnaceae) e o inseto indutor das galhas foliares quanto aos aspectos morfológicos, anatômicos e distribuição da galha no limbo foliar. Foram realizadas coletas nas estações seca (setembro/2015) e chuvosa (dezembro/2015) em 10 indivíduos de O. spectabilis, localizados na mata de galeria, pertencente à Escola de Medicina Veterinária e Zootecnia, da Universidade Federal do Tocantins, campus Universitário de Araguaína. Para a realização dos testes histoquímicos e caracterização anatômica foram utilizados cortes transversais à mão livre das folhas sadias e de galhas. A galha cônica de O. spectabilis possui tricomas diferenciando da folha sadia, que é glabra, internamente apresentaram tecido nutritivo rico em proteína e, de forma geral, os tecidos galígenos são mais ricos em compostos secundários quando comparado com as folhas sadias. O galhador pertence a um novo gênero da família Cecidomyiidae (Diptera). A distribuição das galhas no limbo foliar foi estatisticamente maior na região entre nervuras, independente da posição das folhas no ramo e das estações do ano, e a maior infestação foi verificada no período chuvoso.

Published: August 2019

Apresentam-se os resultados de uma pesquisa que mapeou os riscos psicossociais no trabalho dos policiais militares vinculados à 1º Companhia Independente de Arraias-Tocantins. Utilizou-se o Protocolo de Avaliação dos Riscos Psicossociais do Trabalho (PROART). Participaram 62,7% da população. Utilizou-se estatística descritiva e análise de conteúdo. Os resultados demonstram que o contingente da Divisão de Tarefas (75,7%) mostrou-se propenso a maiores riscos psicossociais que aquele da Divisão Social do Trabalho (62,1%). Há uma leve predominância do Estilo Gerencialista em relação ao Coletivo. Quanto aos riscos de sofrimento patogênico, verificou-se risco baixo para a Falta de Sentido no Trabalho e para a Falta de Reconhecimento, ao passo que o fator Esgotamento Mental obteve risco médio (52,7%). Identificou-se risco baixo para os danos psicossociais e médio para os danos físicos (48,6%). Conclui-se através deste mapeamento que os Policiais Militares desta Companhia estão expostos a Riscos Psicossociais Médios para a forma como a organização é estruturada, sobretudo para o pouco efetivo, pela pouca autonomia e liberdade de expressão, bem como pela interferência política nas decisões da Companhia. Isto representa um estado de alerta onde a organização do trabalho deve intervir em médio a curto prazo para evitar o possível adoecimento de seus trabalhadores.

Published: August 2019

O povo Karajá-Xambioá, também conhecido como Karajá do Norte ou Irarumahadu (povo de baixo), pertencente ao tronco linguístico Macro-Jê, e família língua Karajá, possui uma população aproximada de 543 (DSEI 2016) indígenas, distribuídos em quatro aldeias; Xambioá, Kurehê, Wari Lỹtỹ e Hawa Tamara. Este artigo objetiva uma análise da historicidade dos usos dos grafismos Karajá-Xambioá, fazendo um apanhado histórico e cultural da representatividade e da interface entre o grafismo e o território na composição cultural desse povo. O grafismo possui sentidos diversos, não somente na vaidade, mas na busca pela estética perfeita e pelos valores que são transmitidos através da arte dos traços tradicionais. O problema de estudo trata do contato com o não indígena, que causou danos a história desse povo, com perda de identidade cultural, deixando de praticar seus rituais, dentre eles a sua pintura corporal. Dentre os resultados tem-se o resgate sobre a cultura da “arte indígena”, especificamente o grafismo corporal do povo Karajá-Xambioá, contribuindo para a manutenção e registro das pinturas, além de ser também uma importante peça para a educação escolar indígena do povo, assegurando as memórias e os traços para as futuras gerações.

Published: August 2019

ABSTRACT
This is a descriptive, retrospective cross-sectional epidemiological study, on cases of Congenital Syphilis (CS) reported on the Information System for Notifiable Diseases (SINAN) from 2013 to 2017. This study aims to describe the epidemiological profile of CS cases reported in the eight health regions of the state of Tocantins. The health care regions were related to the variables maternal schooling, prenatal performance, area of residence, moment of diagnosis and treatment of the partner. Of the 1192 cases reported,the majority were in the Capim Dourado region. It was verified that in most cases the mothers studied until elementary or secondary school, performed prenatal care and resided in urban areas, and that the diagnosis occurred during prenatal care, however, the partner was not treated. Only Amor Perfeito region showed a predominance of diagnosis performed at the time of delivery and Ilha do Bananal region was the one with the highest percentage of diagnosis carried out after birth. The increase in SC cases may reflect increase in it’s incidence and improvement in the notification system. The percentage of untreated partners and late diagnoses may suggest a qualitative and an access deficit in prenatal care.

Abstract
The success of hydraulic fracture treatment can be evaluated by measuring fracture conductivity and regained permeability. However, selecting the suitable fracture fluid system plays an essential role to minimize or eliminate the formation damage. To address the potential formation damage during fracturing treatment, this research presents a comprehensive review of a good number of published papers that are carefully reviewed and summarized including experimental research, case studies, and simulation work on recent improvements of using HVFR to carry the proppant and capture the optimum design in fracturing operations. This paper also provides formation damage mechanisms such as chemical, mechanical, biological, and thermal. Moreover, the research explains the fracture damage categories including damage inside fracture and damage inside the reservoir. The advantages of using HVFRs are also fully explained. Experimental rheological characterization was studied to investigate the viscoelastic property of HVFRs on proppant transport. The successful implication of utilizing HVFRs in the Wolfcamp formation, Permian Basin was discussed.
The findings of this research are analyzed to reach conclusions on how HVFRs can be an alternative fracture fluid system of many unconventional reservoirs. Comparing to the traditional hydraulic fracture fluids system, the research shows the many potential advantages that HVFR fluids offer, including superior proppant transport capability, almost 100% retained conductivity, around 30% cost reduction, and logistics, such as minimizing chemicals usage by 50% and operation equipment on location, reduce water consumption by 30%, and environmental benefits. Finally, this comprehensive review addresses up-to-date challenges and emphasizes necessities for using high viscosity friction reducers as alternative fracture fluids.
The Effect of Water Cut on the Producing Trends and Downhole Multiphase Flow Conditions in Oil-Rich Shale Plays
Authors: Nagoo Anand , Kannan Subash 
Published: August 2019

Abstract
The continually evolving water management practices of liquids-rich tight oil operators (for optimizing the water use and costs of their water life cycle) is a topic of major impact. One area during the produced water phase of the water life cycle, is the less understood effect of different water cut fractions of the total fluids production from the formation on both the producing three-phase flow rate trends on surface as well as the downhole multiphase flow conditions, in particular, lateral to bend slugging and loading tendencies. This paper quantifies this effect of varying water cut production in a variety of operational conditions. In order to quantify the effect of varying water cut production, the methodology of this work involves first understanding the basic differences between gas-and-water (100 % water cut) and gas-and-oil (0% water cut) multiphase production in terms of their averaged slip behaviors, and therefore, total pressure gradient observations. We utilize published lab-scale flow loop experiments and a few actual, field-scale wells to demonstrate the different reported behaviors. An analytical multiphase flow simulator is then validated against these observations. Once verified, we then use the simulation tool to perform downhole calculations of flowing bottomhole pressure, gas volume fraction (gas-liquids slip), wellbore flow pattern, difference in wellbore and critical gas velocities and slugging flow characteristics (slugging frequency, velocity and lengths) for a given set of surface operating conditions. The workflows presented in this work will enable a deeper insight into the differences between gas and liquids slip under varying water cut fractions in both lighter condensate fluids as well as denser black oil fluids production. This work adds an improved understanding of the effect of water cut fractions on the total pressure gradient behaviors and downhole multiphase flow slugging and loading behaviors in liquids-rich tight oil developments.
Leveraging Cloud-Based Analytics to Enhance Near-Real Time Stage Management
Authors: Bommer Peter , Iriarte Jessica 
Published: August 2019

Abstract
Normally, the optimization of hydraulic fracturing performance is limited to pre-job modeling and analytics. A design is determined for a particular well or project and applied without significant change during the course of the stimulation. Performance results are collected during the job and then analyzed after the fact, with the primary purpose of designing for the next project.
Significant design improvements can be made by evaluating stage performance in real-time as the well is being stimulated. Unfortunately, real-time analytics are difficult because the immense of volume, variety, and velocity of the available data. The typical frac fleet captures metered data from as many as one hundred measurement points simultaneously on a second-by-second basis. This means that for a single stage, the comma-separated values (CSV) files containing the recorded channels often include over one million discrete data points. Utilizing these large files (approximately 5 MB) with typical off-the-shelf software can be time-consuming. The manual process of file acquisition by analytical staff alone can often exceed the time available between stages. While these files are an invaluable resource, they are often left untouched until long after a job is completed, if they are ever used at all. Cloud-based analytics greatly shorten the acquisition and utilization timeline, making near real-time analysis possible.
While the challenges involved in utilizing "big data"; for actionable analytics are frequently discussed, the technology and approaches described in this paper are relatively new to the field of real-time stage management. This paper introduces a novel and highly effective approach in the field of hydraulic fracturing optimization. The history of CSV analysis is presented along with examples of specific types of beneficial stage analytics.
Prediction of the Fracture Closure Pressure from the Instantaneous Shut-In Pressure ISIP for Unconventional Formations: Case Studies
Authors: Kholy S. M. , Ma J.. , Mohamed I. M. , Abou-Sayed O.. , Abou-Sayed A.. 
Published: August 2019

AbstractHydraulic fracturing is applied ubiquitously in unconventional hydrocarbon reservoir development to increase the well productivity. To design a frac job, an injection falloff diagnostic test, such as minifrac test, is conducted first to determine key formation properties and frac operational parameters, including fracture closure pressure. In low permeability formations, the conventional pressure falloff analysis (i.e. G-function) is not practical to identify the fracture closure since it requires several days of well shut-in to collect enough pressure falloff data to reveal the fracture closure. In SPE-187495-PA, the authors show that it is possible to develop an empirical equation to predict the fracture closure pressure (Pc) from instantaneous shut-in pressure (ISIP), the first falloff data point, by regressive analysis on datasets from minifrac tests for conventional formations, including G-function estimated Pc, ISIP, petrophysical and mechanical properties. Since petrophysical and mechanical properties could be estimated from cores and wireline logs, the application of this equation requires a minifrac test to have a very short falloff period only to estimate ISIP. The objective of this work is to extend that equation for unconventional formations by introducing appropriate deviation terms for tight-sand and shale formations, respectively, in order to reduce the discrepancy between predicted Pc and G-function estimated Pc.To this end, several datasets, each of which contain the same attributes, are collected from publications for shale and tight-sand formations. Part of datasets are selected for developing respective deviation terms, for shale and tight-sand, to be added to the empirical equation, while the remaining datasets are used to test the respective new equation. Then a regression analysis is performed between Pc differences and the individual petrophysical and mechanical properties for shale and tight-sand datasets separately. Eventually, two deviation terms have been derived and incorporated to the empirical equation, one for shale and another one for tight formations.The deviation term for tight-sand formations correlate strongly with the rock mechanical properties, while the other with the rock mechanical properties and the formation porosity. Several field cases have been used to validate the empirical equation with respective deviation terms and the results show that the new formulae predict the fracture closure pressure with a relative absolute error less than 5% compared to those estimated from the G-function analysis for both the shale and the tight formations cases which are not used in developing respective deviation terms.

Published: August 2019

Abstract
BACKGROUND: Huntington’s disease (HD), an inherited, often late-onset, neurodegenerative disorder, is considered to be a rare, orphan disease. Research into its genetic correlates and services for those affected are inadequate in most low-middle income countries, including India. The apparent ‘incurability’ often deters symptomatic and rehabilitative care, resulting in poor quality of life and sub-optimal outcomes. There are no studies assessing disease burden and outcomes from India.
METHODS: We attempted to evaluate individuals diagnosed to have HD at our tertiary-care center between 2013 and 2016 for clinical symptoms, functionality, mortality, follow up status through a structured interview, clinical data from medical records & UHDRS TFC scoring.
RESULTS: Of the 144 patients, 25% were untraceable, and another 17 (11.8%) had already died. Mean age at and duration of illness at the time of death, were 53 years and 7 years respectively, which is much shorter than in Europe and USA. The patients who could be contacted (n=81) were assessed for symptomatic morbidity and total functional capacity (TFC). Mean CAG repeat length and TFC score were 44.2 and 7.5 respectively. Most individuals (66%) were in TFC stage I and II and could perhaps benefit from several interventions. The TFC score correlated inversely with duration of illness (p<0.0001). The vast majority were being taken care of at home, irrespective of the physical and mental disability. There was a high prevalence of psychiatric morbidity (91%) including suicidal tendency (22%). Three of the 17 who died had committed suicide, and many other families reported suicidal history in other family members. Only about half the patients (57%) maintained a regular clinical follow-up.
CONCLUSIONS: This study demonstrates the poor follow-up rates, significant suicidality & other psychiatric symptoms, suboptimal survival durations and functional outcomes highlighting the need for holistic care for the majority who appear to be amenable for interventions.

Abstract
Background
depression is one of the most serious and prevalent mental illnesses that can result in serious disability and ending life by committing suicide and homicide. The risks of having depression are substantially higher in persons who have parental neglect when compared to the general population.
Objective
To detect prevalence of depression and its association with parental neglect among adolescents in governmental high schools at Aksum town, Tigray, Ethiopia 2019
Method
A facility based cross-sectional study was conducted from January 1-30/2019 at Aksum town high schools. Public health questionnaire was used in this study to detect Depression. Study participants were selected using simple random sampling technique. Data was collected with face to face interview. Data was analyzed using statistical package for social science version 22. Bivariate and multivariate logistic regressions were used to see the association between depression and parental neglect. Adjusted Odds ratio at a p-value <0.05 with 95% confidence interval was taken to declare statistical significance of variables.
Result
A total of 624 students were participated in the study yielding a response rate of 99.05%. Prevalence of depression was found to be 36.2%. Depression among adolescents was found to have significant and strong association with parental neglect ((AOR=2.61, 95% CI (1.83, 3.72), p-value=0.000).
Conclusion and recommendation
In the current study the prevalence of depression is found to be high when compared to other population. Significant and strong association is also determined between parental neglect and depression. It is good if school teachers give emphasize for those students who seems psychologically unwell. It is better if school teachers exercise linking such students to school psychologists. It is good to conduct prospective cohort study to investigate temporal relationship between factors and depression. It is good if Aksum university comprehensive hospital start campaign which will teach about the effect of parental neglect on the adolescent’s mental health.

Published: August 2019

Abstract
Background: Therapeutic interchange policies in hospitals are useful in dealing with antimicrobial shortages and minimising resistance rates. However, the extent of antimicrobial shortages and availability of therapeutic interchange policies is unknown among public sector hospitals in South Africa.

Objective This study aimed to ascertain the extent of antimicrobial shortages among public sector hospitals, the presence of current therapeutic interchange policies and the role of pharmacists in the process.

Setting Public sector hospitals in South Africa.

Methods: A quantitative and descriptive study was conducted with a target population of 403 public sector hospitals. Data were collected from hospital pharmacists using an electronic questionnaire, administered via SurveyMonkeyTM.

Main outcome measure Prevalence of public sector hospitals with antimicrobial shortages over the past six months and the prevalence of hospitals with therapeutic interchange policies.

Results: The response rate was 33.5%. Most (83.3%) hospitals had experienced shortages in the previous six months. Antimicrobials commonly reported as out of stock included cloxacillin (54.3%), benzathine benzylpenicillin (54.2%), erythromycin (39.6%) and ceftriaxone (38.0%). Reasons for shortages included pharmaceutical companies with supply constraints (85.3%) and an inefficient supply system. Only 42.4% had therapeutic interchange policies, and 88.9% contacted the prescriber when there was a need for substitution.

Conclusions: Antimicrobial shortages are prevalent in South African public sector hospitals with penicillins and cephalosporins being the most affected. Therapeutic interchange policies are not available at most hospitals. Effective strategies are required to improve communication between pharmacists and prescribers to ensure safe, appropriate and therapeutically equivalent alternatives are available.
