Introduction: Identification of the risk factors that can be modified is an essential aspect in the development of the effective strategy for therapeutic intervention with the purpose to improve mobility and injury prevention and post-fall consequences. This research aimed to analyze the impact of programmed therapeutic exercises on the fall risk factors in the elderly.
Methods: We included 260 patients older than 65 years, and assigned them randomly into three groups. Group A: 65 patients subjected to therapeutic exercises for moderate-intensity muscle strengthening with Theraband stretch straps (corresponding to 11-14 on the Borg rating of perceived exertion scale). Group B: 65 patients subjected to therapeutic anti-gravity exercises. Control group: 130 patients not participating in programmed therapeutic exercises.
Presence of fall risk factors was assessed in all three groups with standardized Fast Evaluation of Mobility, Balance, and Fear test (FEMBAF) before the initiation of therapy, after three and after six months of treatment.
Results: At the end of the study, the subjects of the group A had significantly fewer limitations in performing basic life activities at home compared to the patients of the control and Group B, p = 0.037. The control group subjects were statistically significantly more likely to complain of vertigo than subjects of the experimental groups, p = 0.021. The subjects of the experimental groups had more than two falls than the control group subjects, p = 0.003 statistically. In the control group, the number of fractures after the fall at the end of the study increased significantly, statistically higher than in the subjects of the experimental groups, P = 0.037.
Conclusion: Programmed therapeutic exercise significantly reduces the risk of falling factors, and significant effects have been achieved among subjects who have exercised with elastic strips.

Aim:to investigate safety and angiographic efficacy of two-stage revascularization with percutaneous coronary intervention (PCI) with stenting delayed by one day in patients with acute myocardial infarction (MI) and massive coronary thrombosis.Materials and methods.We included in this study 12 patients with massive infarct related coronary artery thrombus which length was greater than thrice the vessel diameter in the presence of TIMI grade II–III blood flow as detected by coronary angiography (CAG). The emergency PCI was not performed, and conservative antithrombotic therapy continued for 24 hours. After this day, CAG was repeated.Results.Repeat CAG in all patients showed thrombus regression which visually appeared as complete lysis in 8, and partial lysis – in 4 patients. Stenting of residual stenosis was performed in 11 patients without complications. In 1 patient residual stenosis was considered insignificant (<50 %) therefore stenting was not performed. No-reflowphenomenon and recurrent MI were not observed.Conclusion.These data suggest that in patients with massive coronary artery thrombosis conservative antithrombotic therapy for 24 hours followed by repeated CAG and, if required, by stenting of residual stenosis, is safe treatment tactics that might reduce the risk of the no-reflow phenomenon.

Authors: Fedirchyk Tetiana , Nitalia Nikula 
Published: March 2019

The article presents comprehensive analysis of the problem of formation of methodology culture of would-be elementary school teachers in pedagogical theory and educational practice. The problem of the formation of a methodological culture of future teachers of elementary school was studied by us from the standpoint of scientific approaches: cultural; axiological systemic; competent; person-activity approaches. It is established that the concept of "methodological culture of the teacher of elementary classes" is an integral part of the category field in the hierarchy of concepts: “culture” ‒ “culture of the person” ‒ “professional culture” ‒ “vocational pedagogical culture” ‒ “methodical culture”. The theoretical analysis of psychological and pedagogical literature allowed to carry out the pedagogical concrete definition of the concept “methodical culture of the teacher of elementary classes”, which is considered in the work as an integrative set of his professional-personal values and qualities, methodical competence and methodical skills, which allows creatively to carry out professional-methodical activity on the basis reflection, experience and self-development, taking into account regulatory requirements. Structure of methodology culture of an elementary school teacher has been shown as combination of components: value and motivational, cognitive and praxeological, personality and artistic, reflective and evaluational. Criteria, values for levels of formation of methodology culture of would-be elementary school teachers have been elaborated that reflect unity and connection of all structural components of the described phenomenon. Levels of formation of methodology culture of would-be elementary school teachers have been established in the process of professional training: adaptive-repetitive, reproductive, systemic-productive, integrative-creative. Efficiency of the model of formation of methodology culture of would-be elementary school teachers has been proved theoretically and experimentally, which consists of three interrelated units (theoretical and methodical, context and activity, resultative). Teacher’s guides have been elaborated and introduced for formation of methodology culture of would-be elementary school teachers in the process of professional training.

Circunstancias que impiden o condicionan la adopción: el alcance de la denominada “cláusula chadiana” = Circumstances that prevent or condition the adoption: the scope of the so-called “chadian clause”

Resumen: A raíz del caso de la ONG francesa “El Arca de Zoé” y su tentativa de traslado ilícito a Francia de 103 menores, supuestamente huérfanos de la guerra del Chad, el legislador español incorporó en el art.4 LAI la denominada “cláusula chadiana”. Se trata de una serie de condiciones que inciden en la tramitación de la adopción y que sólo vinculan a las autoridades españolas. No obstante, cabe preguntarse si tales circunstancias pueden repercutir igualmente en el sector de la eficacia de las adopciones constituidas por las autoridades de un país respecto del cual rige una de las prohibiciones o condicionamientos previstos en este precepto.Palabras clave: “cláusula chadiana”, Ley de Adopción Internacional, adopción internacionalAbstract: Following the case of the French NGO “Zoé´s Ark” and its attempted illicit transfer to France of 103 children, supposedly orphans of the Chadian war, the Spanish legislator incorporated into the art.4 LAI the so-called “chadian clause”. This is a series of conditions that affect the processing of adoption and are linked to the Spanish authorities. However, it is questionable whether the circumstances can also affect the sector of the effectiveness of adoptions constituted by the authorities of a country to which one of the prohibitions or conditions provided in this precept.Keywords: “chadian clause”, The Intercountry Adoption Act, Intercountry Adoption

Abstract
This paper presents field results of the first well perforating system integrated with a depth correlation and real time high-speed measurements device, this tool acquires and transmits downhole data to surface in real time while perforating. The docking gun system with plug-in design improves operational safety, efficiency and reliability, whereas downhole measurements help to obtain maximum well productivity by providing real-time downhole wellbore pressure, transient dynamic underbalance and/or overbalance for perforation cleanup and/or well stimulation.
The new perforating system consists of two main components: a docking gun system and an advanced measurements module. The docking gun system consists of a compact, plug-in, radio frequency safe, addressable firing system for single and multi-zone sequential perforating applications. The system eliminates port plugs and wellsite arming of detonators, reducing human error and improving overall safety, efficiency, and reliability. The advanced measurements module provides high-frequency transient wellbore pressure, peak acceleration amplitude, and low frequency pressure, temperature, gamma ray, and active casing collar locator. These measurements enable real time confirmation of downhole conditions before, during, and after perforating, with accurate depth correlation even in high chrome tubulars and large casing sizes.
This instrumented docking gun system delivered an outstanding field performance, adding value to operators by increasing safety, efficiency and reliability, while at the same time maximizing productivity. This instrumented gun system can be deployed with wireline, tractor or electrical coil tubing. The new docking gun system design reduces human error and the risk of wellsite accidents and failures. With this system we also maximize gun length deployment per run and operational efficiency. In addition, real time downhole measurements of low- and high-frequency wellbore pressure allow optimization of perforating cleanup and stimulation, maximizing productivity and reducing the overall cost per barrel produced.
Study on Mechanism of Coiled Tubing Surface Damage in Injector Head

Published: March 2019

Abstract
According to literature, most failures of coiled tubing are classified into four kinds of causes, mechanical damage, corrosion, string manufacturing, and human error. Among these, the failures due to mechanical damages take 29% of all failures. Although there are various kinds of mechanical damages, longitudinal plowing marks (LPM) are the major mechanical damages, account for 46%. Understanding the mechanism of LPM damage on coiled tubing surface will help to reduce this kind of damage.
A conjecture is proposed that the running of the CT-gripper block-chain system will produce a period excitation which arouses CT string system resonance, and the vibration of CT string may make slippage between the gripper blocks and CT string at the wave peak and stop slippage at the wave trough, which may form fish scale damage. Because of the mismatch of the diameters between CT with grown diameter and gripper blocks, the first principle stress on the surface of CT will be large enough so that rock debris can carve CT easily when a gripper block is clamping it. FEM is employed to calculate the stress of CT when it is in this situation. The results verify the guess.
To determine the CT string system resonance, we tried to find which gives the system a period excitation and how the system resonates. First a mechanical model of CT-gripper-chain is build, and excitation frequency is found to be related with the velocity of CT string running and length of gripper block. After idealization, a dynamic model for CT string in vertical well is built, and the wave equation is established, then frequency equation is derived and natural frequencies are found. After that, finite difference method is used to conduct numerical calculation. The results show that when system resonates, it must take minutes to reach large stress amplitude of the CT string enough to make damage on it. The field recorded data indicate that there maybe exists resonance actually.
After synthesizing the information above, an image of the process how LPM is formed has been constructed. Finally, the measures to reduce LPM damage are recommended.
Incremental Gains in Coil Tubing Reachability for Highly Restricted Extended Reach Open Hole Completions
Authors: Saiood Hussain , Duthie Laurie , Aybar Umut , Bal Moustapha 
Published: March 2019

Abstract
Successful stimulation fluid placement in extended reach wells (ERW's) through coiled tubing (CT) is primarily dependent on the depth reached for maximum reservoir contact. Well configurations of minimum bypass (2.4 in.) and openhole sections (6 1/8 in.) are the main challenges for CT reach in these ERW's. Implementation of a CT slim tractor along with fiber-optic enabled cable were applied to overcome the challenges and set a new record for CT reach.
CT lockup is the phenomenon that occurs due to friction forces and helical buckling, which limits the CT reach. To tackle these challenges, an accurate simulated lockup depth is estimated using historical data to identify the required pull force. The CT slim tractor (2 1/8-in.) was chosen as the optimum tool to provide the required pull force, as well as pass through the minimum ID restriction of the well. Specially designed tapered CT with fiber-optic enabled cable acquired real-time data from the downhole tension-compression (TC) sub to confirm both the activation and lockup depth of the tractor.
The expansion ratio of the tractor from 2 1/8-in. to 6 1/8-in. OH section opens a new era for CT reach in restricted ERW's. The world slimmest tractor passed the 2.44-in. minimum ID restriction and provided more than a 3,000 lbf pulling force, allowing the CT to cover the entire openhole section. Along the way, two new records were recorded for the longest section tractored by a slim CT tractor and the furthest distance travelled in a producer well reaching a TD of 24,706 ft. Increased reservoir contact during stimulation through engineered solutions has set a new standard enabling the implementation of a full stimulation campaign.
These engineered solutions demonstrate the potential for CT interventions in extended-reach horizontal wells with completion restrictions, where the main challenge is to maximize the reach for optimum stimulation. As a direct result of several innovative solutions applied simultaneously, a new record for CT reach was set, surpassing the previous record by nearly 5,000 ft.
Successful Coiled Tubing Fishing Operation Uses Hybrid Cable Connected Tools to Evaluate/Validate Downhole Data in Real-Time: A Case Study in the Eastern Foothills of Colombia

Abstract
New downhole coiled tubing (CT) technology was used to facilitate the success of a challenging fishing intervention and to verify the reliability and accuracy of CT operations/simulation software. The technology supplies the newly designed bottomhole assembly (BHA) with continuous power from, and fiber-optic communications with, surface equipment, enabling accurate, real-time monitoring of measurements of bottomhole conditions.
Uncertainty exists in operations using CT regarding whether the planned axial force is transmitted from the surface through the pipe to the BHA and whether the BHA is functioning according to plan. During fishing operations, unless the BHA applies a minimum amount of force (compression and/or tension) to the fishing neck, the particular intervention run will be unsuccessful. The BHA then needs to be returned to the surface without recovering the fish.
This paper presents a case study of a well located in the foothills of Colombia in which a perforating gun became stuck following an operational issue. This situation resulted in an oil production reduction of 30%. Several fishing attempts were performed using conventional CT to recover the stuck perforating gun and to restore production to its previous level.
The initial lack of real-time BHA data and the inherent nature of CT elongation and buckling led the operator to believe that the fish was being recovered to the surface; several runs were performed with unsuccessful results. A CT string, equipped with fiber-optic communications and a continuous power supply to the BHA, confirmed that the perceived movement of the fish was not real and that the BHA selected was not generating nor transferring the expected force to the fish. The force transmitted by the pipe and the upward/downward impact force generated by the jar were measured in real time and determined to be consistent with simulated forces; the BHA configuration used for the operation was then redesigned. The new design led to the successful recovery of the fish and the return of well production to its initial level.
The real-time data measured during the fishing operation favorably compared to the simulated forces predicted during job design and execution. The accuracy and reliability demonstrated by the CT simulation software in use enabled the operator to gain confidence in all simulations performed with the software for future CT operations.
This case study is the first known instance in which CT was used in conjunction with downhole tools that were supplied with continuous power to sensors to enable measurement of parameters, including force, pressure, temperature, torque, inclination, phasing, acceleration, gamma ray, and casing collar locator (CCL). This technology was supported by reliable software capable of simulating downhole conditions with precision and accuracy.
