Authors: Leonov M. I. 
Published: November 2018

The article examines the first armed revolutionary demonstration initiated by the SRs on December 5–6, 1904 in Moscow, during which there were acute clashes and which, according to the level of preparedness, scope and immediate consequences, was a landmark event in the life of the ancient capital. The beginning of the Socialist-Revolutionary organization in Moscow at the end of 1896 was put by prominent figures of the Union of Socialist-Revolutionaries, founded in Saratov: Argunov, M.E. Argunova, S.I. Barykov, V.I. Evreinov, A.S. Martynov, V.N. Pereverzev, A.A. Chepik, N.M. Chernov. The Socialist-Revolutionary organization of Moscow by the end of 1904 was considered exemplary in the party of the Socialist Revolutionaries. It conducted active agitation among students, students, intellectuals, workers. In autumn 1904, given the worsening of social tension, the Moscow Committee of the Socialist-Revolutionary Party began organizing an armed demonstration, appointing it on December 5 and 6. Special hopes were placed on the workers of the Prokhorovka Manufactory. December 5, 1904 in the demonstration were involved about two thousand people, mostly students and intellectuals. During the demonstration, violent clashes occurred with the use of weapons, at this time more than 30 people were injured. In the demonstration on December 6, about 300 people participated.The demonstration on December 5–6 was sympathetically received by students and intellectuals. On the leaders of the dispersal of the demonstration, Grand Duke Sergei Aleksandrovich and D.F. Trepov, the SRs organized assassinations. The demonstration on December 5–6, 1904, was the first mass armed revolutionary manifestation in Moscow in the early 20th century. In 1905 armed clashes between demonstrators and government troops became commonplace.
POSSIBILITY AND APPLICABILITY OF PSEUDO-RANDOM CODE FUNCTIONS IN IMPULSE-CODE SEISMIC CONCENTRATION TO OIL AND GAS SEISMOLOGY PROBLEM-SOLVING RESEARCH
Authors: Khasan R. E. , Kostrygin Yu. P. 
Published: November 2018

The applicability of pseudo-random code functions in impulse-code seismic concentration to oil and gas seismology problemsolving has been assessed through the comparative analysis of correlation functions in compliance with pseudo-random pulse sequences and linear change in pulse repetition sequences. The research shows that the correlation functions’ main peaks spectrums of pseudo-random pulse sequences are almost equal to the single impulses’ spectrums used for the sequences development. The given circumstance reflects the general possibility of pseudo-random sequences applicability to oil and gas seismology problemsolving. However, pseudo-random sequences are characterised by the increased interference level of correlative transformation, which makes the use of pseudo-random code functions in oil and gas seismology inappropriate. It is noted that not only are impulsecode pseudo-random signals characterised by high-amplitude correlation noise, but also all the other pseudo-random complex signals, e.g. random quasi-harmonic signals, contained in modern vibroseis management systems.
Fundamentos de la semiótica jurídica. Hacia una semiótica del Derecho penal
Authors: Moya Vargas Manuel Fernando 
Published: November 2018

Historiográficamente, el Derecho se caracteriza por el predominio de la hermenéutica y de la dogmática. Esta condición se manifiesta en una epistemología cuyo método ha enseñoreado el aspecto técnico del saber jurídico. Consecuencia de lo cual ha sido, como sucede con la mayor parte de las ciencias sociales y humanas, la discreta importancia que han terminado otorgando a la sociedad y al ser humano, a los cuales reducen en tanto legos, a nudos e impotentes destinatarios de las instituciones jurídicas. De esta forma, el Derecho ha sido capitalizado por los técnicos, quienes se han desembarazado de “los demás”, transfiriéndolos a la sociología jurídica, la cual sin embargo no ha tenido por empeño el desarrollo de la ciencia del Derecho. En contraste, la semiótica del Derecho, semiótica jurídica o semiótica de la justicia, reivindica al ser humano y a las sociedades, en tanto las restablece en su condición auténtica de comunidades de hablantes del Derecho que, a través de procesos comunicativos para los cuales usan los signos jurídicos, crean y transmiten su propio sentido de justicia.
Approcher la densité des ligneux par l’indice perpendiculaire de végétation : cas d’une savane arborée au nord de la Tanzanie

Published: November 2018

Le domaine de Namalok (4 500 ha), situé au nord-est de la Tanzanie, a été protégé par TPC Limited, une société sucrière privée, pour en faire une réserve privée de faune et de flore. La végétation locale est constituée de savanes arbustives à Salvadora persica, de fourrés de Suaeda monoica et de savanes arborées plus au moins denses à Acacia xanthophloea, Faidherbia albida et Acacia tortilis. Afin de répondre à un objectif de gestion suite à la réintroduction de grands herbivores, la composition floristique de ces formations ligneuses a été étudiée en association avec une approche cartographique du degré d’accessibilité des formations ligneuses par les herbivores, exprimé en classes de densité établies selon l’indice perpendiculaire de végétation (IPV). Les résultats révèlent tout d’abord une corrélation très élevée entre la densité calculée des ligneux et l’IPV (r2 = 0,96) et confirment l’intérêt de l’approche proposée d’analyse d’images satellitaires. Dans une perspective plus locale, ils montrent aussi que, sur le plan floristique, les niveaux successifs des densités cartographiées sont composés de 70 espèces végétales et relèvent d’un fond floristique d’espèces pantropicales. Ces savanes montrent également une distribution spécifique relativement équitable et très diverse, avec des fréquences spécifiques voisines les unes des autres. Les savanes arborées représentent 38 % de la surface du domaine. Par ordre croissant de densité, les savanes de moins de 100 arbres/ha couvrent 836 ha, celles comptant 100 à 200 arbres/ha occupent 654 ha et celles ayant des densités de 200 à 300 arbres/ha sont assez peu importantes et n’occupent que 206 ha. Les savanes de densité supérieure à 300 arbres/ha représentent des étendues beaucoup moins vastes, soit seulement 22 ha.

L’étude visait à caractériser la populationnaturelle d’un ligneux alimentaire, Neocarya macrophylla (Sabine) Prance (Chrysobalanaceae). Elle a été conduite dans le Dallol Bosso au sud-ouest du Niger. Les données provenaient de relevés floristiques dont le dispositif de sondage était de type systématique. Onze transects ont été installés, et 83 placettes de 50 m x 50 m ont été échantillonnées. La structure de la population a été renseignée par ladiversité floristique, la densité des arbres, le taux de régénération et la structure démographique des populations. Une classification ascendante hiérarchique de la matrice espèces-relevés a été réalisée afin d’identifier des groupes végétaux. À l’intérieur de chaque placette, ont été relevés le diamètre à 1,30 m pour les sujets de diamètre supérieur ou égal à 5 cm, et le nombre d’individus. Le coefficient générique reste faible et les familles et genres représentés par une seule espèce demeurent prépondérants. La flore recouvre 36 espèces ligneuses réparties en 30 genres relevant de 19 familles, pour lesquelles dominent les Fabaceae (27,8 %) et les Malvaceae (13,9 %). Trois groupes structuraux apparaissent, caractérisés par une dominance de N. macrophylla, dont la population tend à se régénérer. Les histogrammes de structure des populations font en effet apparaître des effectifs élevés dans les classes de petit diamètre. La densité moyenne de l’espèce est de 26,1 individus/ha, mais varie en fonction des groupes structuraux. L’observation de la régénération naturelle, dont le niveau élevé ne préjuge toutefois pas du devenir des plantules, montre que N. macrophylla se renouvelle essentiellement par semis (87,6 %), et faiblement par rejets de souche (11,1 %). Les résultats de cette étude permettent de mieux appréhender le statut de cette espèce, en faveur de la mise en place de stratégies de gestion durable.

ESP Metallurgy in High-Speed Liquid Droplets/Jets Applications
Authors: Aljishi Hassan , Aljizeeri Ali 
Published: November 2018

Abstract
Liquid impingement erosion has been identified as a potential damage and failure source in many Electrical Submersible Pumps (ESPs) in the oil & gas business. Erosion causes a progressive loss of materials from the housing of the electrical submersible pump which decreases its structural integrity and leads to its failure. Consequently, this subject has been studied widely in many research papers in the oil and gas industry, and many materials have been developed and commercialized to resist it and protect the equipment from any potential wearing.
The goal of this paper is to show the role of erosion in degrading the ESP performance and life and to provide an experimental comparative study of several materials used for encountering erosion for onshore and offshore fields in Saudi. Also,A cost-benefit analysis of some erosion resistant alloys was presented to help engineers to decide when to use these materials if the application requires.
The result of this methodology shows that well fluid characteristic plays a significant role in determining the amount of erosion. Well fluid is a multi-phase flow (gas, oil, and water), and the S.G of water is higher than oil. According to that, the damage that water particles produce is greater than oil. Therefore, when the percentage of water in the well fluid goes high, it increases the damaging impact on the ESP housing, especially when the velocity of fluid over the motor is high ~ 13 ft/s. Erosion resistant alloys should be used and implemented for these cases. Examples of materials include:12-Chrom, 9-Chrome, Carbon steel and stainless-steel coating.
Finally, this paper provides engineers with guidelines/recommendations for selecting the proper metrology for equipment running in wells with high water cut & fluid velocity.
Reducing Non-Production Time with P2P Thru-Tubing Conveyed ESP System

Published: November 2018

Abstract
Electrical submersible pumping system (ESP) failures introduce many issues to operators and reservoirs. These issues can significantly increase operational expenditure (OPEX), especially in areas where it is challenging for workover rigs to operate or the rig cost is very high. In addition, production loss due to workover rig availability, mobilization, and climate challenges presents a major problem to operators to produce economically from this type of well.
Thru-tubing conveyed ESP (TTC ESP) using a pump-to-pump (P2P) connection allows wireline installation of a pump section followed by an additional tandem pump(s) installed on top of the first. Special profiles on the upper section of the lower tandem allow the shaft and housing engagement to match the lower section of the upper tandem pump. TTC with P2P helps reduce ESP installation time in areas where workover rigs cannot be mobilized during the winter season and the cost of intervention is very high. Several pump-to-pump systems were installed without issues and run in environments that were challenging for a conventional ESP.
The system was designed for economic production of recently fractured production wells by allowing low-cost replacement of the primary failure component, the ESP centrifugal pump. Current systems are too long to fit inside practical length wireline lubricators, so this new connection allows shorter pump sections to be stacked sequentially. Additional sections also allow higher head (increased number of stages) for deeper applications. This technology is currently achieving "blind" tandem pump installations at setting depths approaching 8,000 ft.

Abstract
The objective of this project was to install a capillary string attached to the production tubing and inject continuously corrosion inhibitor using electric chemical skid unit on the surface, controlling the doses according to the specific flow rate per well, and improve continuous rod life by extending MTTF.
To achieve the above mentioned objective, the well selection was focused on candidates with a declared corrosion-fatigue mode of failure, with bad actor wells of run life between one and three months. Once the candidates were identified, fluid samples were collected and sent to the lab to identify the corrosion source and categorize the corrosive level of the fluid, however this key information will define the chemical type and the specific daily doses. The chemical skid unit was designed and engineered to set the correct injection doses to maintain continuous treatment and avoiding waste. The use of chemical corrosion inhibitor programs has proven to be a cost-effective approach to minimize corrosion damage and to extend the life of downhole equipment. For this study, we have installed a capillary string attached to the production tubing string and Sucker Rod pump.
The capillary string has been successfully installed at pump seating depth (4,500 ft.). Chemical injection was commissioned at a rate of 5L/day, equivalent to approximately 60 PPM; the injection unit works as expected.
To have an efficient and effective product injected into the well, proper chemical selection considerations need to be taken.
After two months, a corrosion coupon installed in the flowline was removed to evaluate the effectiveness of the program. The analysis confirmed a reduction on the corrosion rate. The well selected has successfully achieved six months run life and still is running.
The continuous rod string was pulled out after six months and found in good condition.
This paper is intended to demonstrate the added value for fields where corrosion leads to regular downhole equipment failures, and providing a clear methodology of well selection and cost-effective solutions implementation, to reach an improved target of MTTF and ultimately of Operational Expenditures Reduction.

Abstract
Surveillance and deep analysis of the performance of artificial lift systems in a field are fundamental for continuous improvement. A field data analysis was conducted to determine the appropriate configurations of electrical submersible pumps (ESP) for the field and to identify how the implementation of the improvement plans resulted in the increase of mean time between failure (MTBF).
The investigation and exhaustive data analysis of the common root causes of failure identified in the failure analysis of the ESPs and analysis of the challenging conditions presented in the field, such as fluid characterization, decline of reservoir pressure, workover intervention procedures, and ESP technology currently applied in the field, enabled determining the specifications required of the ESP equipment to avoid premature failures (run life less than 90 days). The analysis included a specific matrix for root cause identification and several lessons learned over the 32 months of experience in this mature field.
The methodology used for this investigation included the recompilation and analysis of data on failed ESPs and knowledge of specific parameters of the field and applications (wells and fluids produced). The methodology enabled the operator and service companies to achieve greater run life and improve valuable indicators such as MTBF and failure index. After the implementation of the improvement plans, the index of premature failures (ESP failures with less than 90 days) was reduced by 86%from the first to the third year.
An increase of 66.6% of survival probability compared in a 1-year period (comparing year 1 to year 3) was also achieved for the entire ESP population operating in this field.
The thorough knowledge of the well conditions, including production, surface facilities, chemical treatment, and electrical parameters, by the artificial lift engineers and the operator’s engineering department helped in developing appropriate applications for the studied field.
With the knowledge of a field, it is possible to determine the appropriate artificial lift ESP configuration and best operational practices for production and technology. This knowledge allows the operator to be aware of changes to the budget in considering equipment fit for the operating environment, which results in improved run life, thus minimizing the deferred production and preserving the reservoirs through the reduction of well interventions.

Published: November 2018

Background:
Closely related to causes of various diseases such as rheumatoid arthritis, septic shock,
and coeliac disease; tyrosine nitration is considered as one of the most important post-translational modification
in proteins. Inside a cell, protein modifications occur accurately by the action of sophisticated cellular machinery.
Specific enzymes present in endoplasmic reticulum accomplish this task. The identification of potential tyrosine
residues in a protein primary sequence, which can be nitrated, is a challenging task.

Methods:
To counter the prevailing, laborious and time-consuming experimental approaches, a novel computational
model is introduced in the present study. Based on data collected from experimentally verified tyrosine
nitration sites feature vectors are formed. Later, an adaptive training algorithm is used to train a back propagation
neural network for prediction purposes. To objectively measure the accuracy of the proposed model, rigorous
verification and validation tests are carried out.

Results:
Through verification and validation, a promising accuracy of 88%, a sensitivity of 85%, a specificity of
89.18% and Mathew’s Correlation Coefficient of 0.627 is achieved.

Conclusion:
It is concluded that the proposed computational model provides the foundation for further investigation
and be used for the identification of nitrotyrosine sites in proteins.

Background:Cancer remains one of the most serious disease worldwide. Robust metabolism is the hallmark of cancer. PPAT (phosphoribosyl pyrophosphate amidotransferase) catalyzes the first committed step of de novo purine biosynthesis. Hence PPAT, the key regulatory spot in De novo purine nucleotide biosynthesis, is an attractive and credible drug target for leukemia and other cancer therapeutics.Objective:In the present study, detailed computational analysis has been performed for PPAT protein, the key enzyme in de novo purine biosynthesis which is inhibited by many folate derivatives, hence we aimed to investigate and gauge the inhibitory effect of antifolate derivatives; lomexterol (LTX) methotrexate (LTX), and pipretixin (PTX) with human PPAT to effectively capture and inhibit De novo purine biosynthesis pathway.Methods:The sequence to structure computational approaches followed by molecular docking experiments was performed to gain insight into the inhibitory mode, binding orientation and binding affinities of selected antifolate derivatives against important structural features of PPAT. Results: Results indicated a strong affinity of antifolate inhibitors for the conserved active site of PPAT molecule encompassing a number of hydrophobic, hydrogen bonding, Vander Waals and electrostatic interactions.Results:Results indicated a strong affinity of antifolate inhibitors for the conserved active site of PPAT molecule encompassing a number of hydrophobic, hydrogen bonding, Vander Waals and electrostatic interactions.Conclusion:Conclusively, the strong physical interaction of selected antifolate inhibitors with human PPAT suggests the selective inhibition of De novo purine biosynthesis pathway by antifolate derivatives towards cancer therapeutics.
