Objetivo: Determinar la relación del uso del chat y los juegos en red en las habilidades sociales de los alumnos de primer y segundo año de Ingeniera Sistemas y Psicología. Metodología: Se empleó una muestra no probabilística de muestreo por conveniencia de estudiantes universitarios de la Universidad Peruana Unión de Lima, incluyendo universitarios de ambos sexos con edades entre 15 y 25 años. Resultados: Los resultados indican que los alumnos de la carrera de Ingeniería de Sistemas (50%) se caracterizan por hacer un uso moderado del chat. Por otro lado, se observa que los de Psicología (50%) a comparación de los de Ingeniería de Sistemas (16.3%) utilizan muy poco el chat. En cuanto a los juegos en red, en Psicología (96.4%) se caracterizan por jugar muy poco juegos en red al igual que la carrera de Ingeniería de Sistemas (63.8%). Aunque los de la carrera de Ingeniería de Sistemas (30%) presen- tan un nivel de uso promedio de los juegos en red y con respecto a habilidades sociales tenemos que en la carrera de Psicología (97.6%) se caracterizan por tener un nivel de habilidades sociales altas. De manera similar también ocurre con la carrera de Ingeniería de Sistemas (91.3%).Conclusiones: Por lo tanto, la relación de correlación nos indica que existe una relación negativa y altamente significativa entre el uso del chat y las habilidades sociales (r= - 0.419, p< 0.01). Esto quiere decir que cuanto menor es el nivel de uso del chat, mayor es el nivel de habilidades sociales. Asimismo, existe una relación negativa y altamente significativa entre el uso de los juegos en red y las habilidades sociales (r = - 0.215, p< 0.01). Esto quiere decir que cuanto mayor es el uso de los juegos en red menor son las habilidades sociales.

Published: August 2024

Recently, the advancement in sustainable methods for fabricating novel metabolites is one of the prime challenges in metabolic engineering. The current increase in fuel prices and its limited supply made the scientific community more concerned about finding an alternate source of fuel generation. Scientists are now interested in biofuel because of its low cost and ease of production. An intriguing area of research in metabolic engineering is using imaginative manipulation of microbes to manufacture chemicals or molecules of commercial importance. One such bacterium whose commercial potential is rapidly attracting the attention of the scientific fraternity is Cyanobacteria, which are either single-celled or multi-cellular filamentous photosynthetic organisms that can also fix CO2. The generation of biofuel has been transformed by the use of CRISPR (clustered regularly interspaced short palindromic repeats) technology in cyanobacteria, which allows for precise genetic alterations to improve their metabolic processes. Scientists can effectively modify the cyanobacterial genome using CRISPR to increase lipid accumulation, maximize photosynthetic efficiency, and enhance stress tolerance. Cyanobacteria have gained attention in the scientific community as a potential source for biofuel production due to several advantageous characteristics like photosynthetic capacity, genetic manipulation, lack of dependency on fertile land, high biomass yield, versatile biofuel production etc. which our present manuscript aims to catalogue. Cyanobacteria play a pivotal role in developing environmentally friendly energy solutions by converting CO2 into renewable energy sources, serving as a flexible platform for producing different types of biofuels and reducing greenhouse gas emissions.

Este relato de experiência parte da ideia de deaf gain, desenvolvida pelos Estudos Surdos, para pensar em estratégias de educação visual no ambiente escolar. A partir da reformulação da surdez enquanto forma de diversidade sensorial e cognitiva, buscamos refletir de que forma a educação escolar de pessoas surdas pode ser potencializada através do uso das imagens em movimento. Afinal, sabemos que a “competência para ver” não é algo inato e pode ser aperfeiçoada através do uso das tecnologias visuais. Para tanto, utilizamos a exibição do curta de animação Fazendeiro, do diretor espanhol Albert Mielgo, em uma aula de Filosofia do 1º ano do Ensino Médio do Colégio de Aplicação do Instituto Nacional de Educação de Surdos – CAp/INES, para proporcionar uma vivência pedagógica centrada na linguagem cinematográfica e que também servisse de ponto de partida para a discussão de temas de grande relevância em nossa sociedade.

Aim: Normal tension glaucoma (NTG) is a common optic neuropathy that can be challenging to diagnose due to the intraocular pressure remaining within the normal range. Early diagnosis and intervention are crucial for the effective lifelong management of patients.
Methods: This study recruited a total of 225 participants. Small extracellular vesicles (sEVs) RNA from circulating plasma was analyzed via transcriptomic sequencing, and its expression levels were verified by quantitative real-time polymerase chain reaction (qRT-PCR). Logistic regression, linear regression, and receiver operating characteristic (ROC) curve analyses were performed to examine the association of biomarkers with clinicopathological characteristics.
Results: Analysis of sEVs mRNAs in NTG patients revealed mitochondrial dysfunction and enrichment of central nervous system degenerative pathways, reflecting the pathological features of NTG. Compared with those in the controls, the expression levels of sEVs let-7b-5p in the plasma of NTG patients were significantly lower, with an area under the curve (AUC) of 0.870 (95%CI: 0.797-0.943) (P < 0.0001), and the AUC combined with age was 0.923 (95%CI: 0.851-0.996) (P < 0.0001). In addition, we found that let-7b-5p levels were significantly correlated with the severity and visual field defects of NTG patients and had good specificity compared with other ophthalmic diseases.
Conclusion: The sEVs RNA signatures in circulating plasma from NTG revealed mitochondrial dysfunction and that sEVs let-7b-5p can be a useful noninvasive biomarker for NTG.

Background:
Corrective osteotomy for intra-articular malunion is a challenging procedure. However, recent advancements, including patient-matched instruments created on the basis of preoperative computer simulation, enable accurate intra-articular correction. We hypothesized that intra-articular corrective osteotomy using patient-matched instruments for the treatment of distal radial intra-articular malunion would reduce intra-articular deformity and restore wrist function at 12 months of follow-up.

Methods:
This prospective study included 12 patients with distal radial intra-articular malunion who underwent intra-articular corrective osteotomy external to the joint using patient-matched instruments. The primary end point was the maximum step-off on the articular surface of the distal radius, measured with use of computed tomography (CT), with an expected postoperative value of ≤1.5 mm. The secondary end points included the gap of the articular surface; range of motion; grip strength; pain evaluated using a visual analog scale (VAS); patient satisfaction; Disabilities of the Arm, Shoulder and Hand (DASH) score; and Patient-Rated Wrist Evaluation (PRWE) score. A mean postoperative step-off of ≤1.5 mm for the primary end point was assessed with use of the 1-sample t test. The secondary end points were assessed with use of the Dunnett multiple comparison test.

Results:
The average step-off significantly improved from 3.75 ± 1.04 mm preoperatively to 0.51 ± 0.40 mm at the 52-week postoperative follow-up and was maintained within 1.5 mm. The average wrist and forearm range of motion, VAS score, grip strength, DASH score, and PRWE score significantly improved. Eleven patients were either very satisfied or satisfied with their outcomes.

Conclusions:
The use of patient-matched instruments could contribute to improving postoperative outcomes of intra-articular corrective osteotomy procedures involving the distal radius.

Can we Estimate a Fatigue Life for Sucker Rod Materials?
Authors: Bühler M. , Lopez E. , Pereyra M. , Oliva E. 
Published: August 2024

Abstract
This paper aims to discuss the behavior, focused on data distribution of fatigue life for different sucker rod grades in pure fatigue and corrosion fatigue mechanisms. Analysis of the impact from several variables and the accuracy to estimate a fatigue life.
Fatigue - and more frequently - corrosion-fatigue is a major cause of premature failures in the oil and gas industry. Various technical conditions affect fatigue life and fatigue crack growth such as the material surface condition, residual stress, bulk material properties, stress conditions (multi axial, amplitude constant or variable) and environmental influence. All these conditions lead to a stochastic (not deterministic) behavior of the component. I.e., the fatigue lives of similar components under the same conditions (loads, environment) can be significantly different.
Scatter in fatigue is an inherent characteristic of materials. The performance of a sucker rod under fatigue and corrosion fatigue conditions depends on many factors, including the environment characteristics, the material properties, and the applied stresses, giving as result a stochastic behavior.
Literature available to date on this matter suggest that statistical aspects of fatigue of material are well recognized. The sources of this scatter can be essentially different for the crack initiation period and crack growth period.
Tenaris performed extensive and abundant corrosion fatigue tests at the same stress conditions to obtain the distribution function of the fatigue life. Tests were performed in fatigue tensile testing machines equipped with enclosed chambers covering the whole surface of full-scale rod samples (1" diameter × 2 ft length).
Results of corrosion fatigue testing for particular sets of samples were analyzed under Weibull density function. Even at Lab conditions with all the testing parameters as much controlled as possible, there is a dispersion of results.
The fatigue behavior of a material, mainly in its early stages, i.e. crack initiation and growth, is governed by stochastic factors giving a particular probability distribution of failure occurrence under this phenomenon. Understanding these features provides a good tool to analyze the performance of sucker rod strings and design solutions to improve the fatigue life of components.
Innovative Electric Submersible Plunger Pump System Driven by Linear Permanent Magnet Motor as A Technological Alternative for Conventional Rod Pumps in San Joaquin Basin Wells

Published: August 2024

Abstract
New technology has been successfully deployed to reduce the numbers of repetitive failures in conventional rod pump systems and down production associated with failures by using an Electric Submersible Plunger Pump system (ESPP) with a Linear Permanent Magnet Motor (LPMM) in vertical and deviated wells. With this new technology, production efficiency is improved compared to conventional rod pump systems. In addition, wellsite aesthetics are enhanced, which is an important feature of this technology for urban areas. A downhole reciprocating pump is driven by LPMM which replaces a long stroke rod pump that has lower reliability based on frequent failures. The ESPP with LPMM was situated in the well to avoid free gas. The ESPP with LPMM system has achieved steady production due to a unique algorithm that controls the LPMM speed and assists with difficult operational conditions resulting from sand or gas interference. The variable speed drive (VSD) is adapted from a conventional electric submersible pump controller. The motor operating temperature is low due to intermittent loading on the motor and the idle time between each stroke. The power consumption was lower than previous rod pump systems while producing similar production rates. These power measurements show a reduction in power usage of over 50% compared to traditional rod pump systems. Currently, the ESPP with LPMM unit is operating under the initial projected parameters with no failure to date, and a second unit was recently installed in the field. Furthermore, this technology maintains high energy efficiency while eliminating potential leaks from the wellhead stuffing box with a rod string. Thus, there are no methane emissions, very low noise and low surface visual clutter during production activity. Lower cost is derived from the reduction in the number of workover interventions compared to other conventional and unconventional pumping systems.

Published: August 2024

Abstract
The paper presents a methodology for optimizing Gas lift wells, aimed at enhancing the gas injection pressure and consequently deepening the gas injection point to improve the gas lift performance.
An in-depth evaluation is performed to optimize the gas lift method, employing both simulation software and in-house developed gas lift tools. The process involves the strategic installation of Side Pocket Mandrels (SPMs) equipped with Injection Pressure Operated (IPO) valves and Venturi valves at specific depths to optimize gas injection points. The analysis also looked the impact of installation of Pressure Control Valves (PCVs) in the Gas lift pipe line networks, which in computer simulations showed potential to increase gas injection pressure. The increase in pressure enables the optimization of the gas lift wells, thereby improving well performance. The comprehensive nodal analysis and calibration pressures were applied to fine-tune the gas lift designs, considering the individual characteristics of expected targeted wells.
In the simulated scenarios, the newly evaluated methodology improves gas lift wells’ efficiency by 18%. The PCV installation and subsequent adjustments in injection pressure enables the targeting of deeper gas lift injection point, optimizing the gas lift performance and enhancing drawdown and overall well productivity. The custom-developed real-time gas lift monitoring system was pivotal in continuous performance evaluation, allowing for immediate detection and resolution of issues such as gas re-circulation and valve leaks.
This paper introduces innovative techniques and methodologies in gas lift optimization, particularly emphasizing the development and utilization of a proprietary real-time monitoring system for gas lift operations. This system represents a significant advancement in the field, enabling real-time diagnostics, troubleshooting and optimization across multiple wells. The integration of gas lift rig-less technologies is also proposed to enhance the economic viability and operational efficiency of gas lift systems. This innovation marks a significant advancement in artificial lift methods, presenting a more efficient and integrated approach to Gas Lift performance monitoring.
