Este trabalho investiga quantitativamente a trajetória da blogosfera científica brasileira através de dados estatísticos. A amostra é constituída por 346 blogs científicos do banco de dados Anel de Blogs Científicos, que compreende grande parte dos blogs científicos no Brasil, verificando a atividade destes entre as datas da primeira postagem e a postagem mais recente até novembro de 2015. São analisados dados sobre gêneros de blogueiros, temática científica, distribuição regional e tempo de atividade dos blogs, e curva de crescimento dos blogs ativos. Os resultados mostram que em 37% dos blogs participam mulheres e em 74% dos blogs participam homens; a temática predominante é a de Ciências da Vida; a maioria dos blogs se concentra nas regiões Sul e Sudeste do país; e a vida média sobre todos os blogs é de 4,8 anos, com um coeficiente de variação de 0,58. Um achado importante é que o número de blogs ativos parece ter diminuído nos últimos anos. Conjecturamos que esse fenômeno é devido à concorrência com outras mídias sociais (Facebook, Twitter e video blogs), entre outras possíveis causas.
Application of Data Mining for Quick Root-Cause Identification and Automated Production Diagnostic of Gas Wells With Plunger Lift
Authors: Singh Ajay 
Published: January 2017

Summary
The paper presents an application of the classification-and-regression-tree (CART) technique as a root-cause identification and production diagnostic tool, and presents case studies from real field data for gas wells using the plunger-lift system. Specifically, regression-tree analysis was performed on the basis of the available operation data. The regression-tree model is data-driven and easy to construct, and does not require all the parameters that a first-principles-based model often requires. Thus, these models are quite useful in cases where real-time data or the required data for a detailed analysis are unavailable. To improve prediction capability, a cross-validation technique was used to optimize tree size. A total of 8 to 10 variables that could potentially affect the gas-production rate was considered, with case studies conducted on actual field data. Questions, such as which group of wells is performing well or poorly, are quickly answered. Regression-tree analysis, when applied at the field level, can identify a group of wells that underperform compared with other wells. As a result, an asset team can prioritize wells identified as poor performers. Further, a statistical analysis helps to gain insight into understanding the causal relationship between the gas-production rate and various operational variables. On the basis of this analysis, recommendations are also provided to improve the gas-production rate of poorly performing wells. Individual-well models were also constructed to identify the root causes for high or low gas production on the basis of operational changes made during a certain period of time. Only a few of the variables were found to have a significant impact on gas production. The interpretation of the decision tree indicated that additional operational variables, such as production time and pressure-buildup time, should be included in the regression-tree analysis to improve the diagnostic process. This paper summarizes these conclusions and recommends future work to improve the prediction capability of the regression-tree analysis.
An Analytical Solution for Pseudosteady-State Flow in a Hydraulically Fractured Stratified Reservoir With Interlayer Crossflows

Published: January 2017

Summary
This work presents an analytical solution for the pseudosteady-state (PSS) flow in a hydraulically fractured stratified reservoir with finite fracture conductivity in the presence of interlayer crossflows. Specifically, a three-layer configuration is considered, with the midlayer hydraulically fractured and sandwiched between two adjacent layers feeding the midlayer by crossflows. The circular drainage area is approximated as elliptical, allowing the problem to be solved in elliptical coordinates analytically. Explicit expressions in the physical-variable space for the dimensionless productivity index (PI) and the wellbore-pressure drawdown for the PSS flow of such a hydraulically fractured system with interlayer crossflows are derived for the first time. Compared with the case without interlayer crossflows, the dimensionless PI is reduced because of additional pressure drawdown occurring in the sandwiching layers; on the other hand, the time rate of increase of the pressure drawdown at the wellbore is also decreased because of the addition of the producible fluid stored in the sandwiching layers. This slower time rate of increase of the wellbore-pressure drawdown prolongs the PSS production period, which can lead to a larger accumulative production. It is also shown that when the layers have comparable thickness, fracturing the higher-permeability layer provides the best performance because the wellbore-pressure drawdown experiences the slowest time rate of increase during the PSS flow period. The analytical solution can also be used for fracture-design optimization as well as production-decline analysis for fractured stratified systems.
The Effects of Perforation Erosion on Practical Hydraulic-Fracturing Applications
Authors: Long Gongbo , Xu Guanshui 
Published: January 2017

Summary
Predicting perforation erosion and its effects on fracture dimensions, fluid distribution, and pressure drop can be an essential part of successful design of hydraulic-fracturing treatments, especially for massive treatments along the horizontal wells when limited-entry techniques are implemented. Both the perforation diameter D and discharge coefficient Cd increase dynamically as proppant-laden slurries are pumped through perforations, making it necessary to consider the changes of these two variables in terms of time to predict the perforation-erosion effects. In this paper, we conduct a study of the perforation-erosion effects by implementing our new perforation-erosion model derived from experimentally verified abrasion mechanisms to calculate the rate changes of these two variables and the consequent influence on the fracture dimensions, fluid distribution, and downhole pressure during a treatment. The selected parameters affecting the erosion effects in the study include perforation number, perforation-cluster spacing, in-situ stress difference, and fracturing-fluid viscosity. The results demonstrate that our model can predict the perforation-erosion effects on practical hydraulic-fracturing applications in a physically clear and mathematically concise manner under different circumstances by inspecting the simultaneous increases of D and Cd separately, leading to more-appropriate treatment designs, especially with the limited-entry techniques.

ROMANS AND THEIR ‘MEDICAL LAW’ (CRIMINAL LAW ASPECTS) Summary Medicine began to be regulated by law already in the antiquity. Securing the public interest, the Roman legislator made attempts to protect his citizens from certain blameworthy medical practices. There are sources available showing cases of doctors (medics), midwives and pharmacists being criminally prosecuted as a result of the fatal consequences of their medical and quasi-medical activities. The Roman law would impose criminal liability for the acts of administering poison instead of a medicament, bans on sterilization (castration), bans on abortion, criminal liability for causing the death or bodily injury of another man’s slave as a result of his improper treatment (imperitia). Doctors could be divided into private doctors, hired by private persons, and public ones, who were employed and paid by municipalities. Public doctors had to be highly qualified and enjoy an immaculate reputation. Nonetheless, the requirements demanded of doctors did not change the generally negative opinion on medics as held by the Roman society.

<p><em>According to psychological development of young child at elementary school, at least there are two main reasons of visual stimulative utilization using fine art work in teaching-learning process. The first, visual stimulation is more interesting thing to enrich child motivation in learning because the students will enjoy the process, the materials can be explained easily, teaching method will be varied and the students will involve themselves in teaching-learning process, not only listening the lesson from teacher but also observing, searching or demonstrating massage of the illustration. The second, visual stimulation is appropriate to psychological development of the children in the elementary school because this media explain the abstract concept become the concrete one and simplify the complexity of the lesson. It is very important to PAI learning process which much of it’s materials consist of the abstract concept. More over using visual stimulation will give the teacher positivity to make Joyful Learning which students may learn not under pressure and the learning process of PAI will be productive, full of creativities, activities, effectiveness and joyfulness. </em></p><p> </p><p><strong><em>Keywords</em></strong><em>: Visual stimulation, psikologis development</em>.</p>
