La corona, la cruz y el corazón. Alianzas y rebeldías en cartas a san Antonio de Padua
Authors: Kalman Judith
Published: December 2021

En un restaurante en el centro de México, los dueños colocaron una figura de san Antonio de Padua, parado de cabeza. Al poco tiempo de inaugurarse, en apego al culto tradicional a san Antonio, los propietarios empezaron a encontrar cartas adheridas a la superficie del santo, por lo que decidieron ubicar un atril con un libro de actas donde comensales podrían escribirle una carta al santo. El contexto de un espacio con motivos religiosos en un restaurante creó un espacio híbrido de lo sagrado y lo profano, un contraste que se observa en las cartas que las comensales allí escribieron. La finalidad de este artículo es examinar algunas de estas cartas y explorar las semejanzas y diferencias entre ellas en su estructura, tono, uso de lenguaje y discurso. Se ilustra cómo las diferencias se explican por la coexistencia de posibles posicionamientos y prácticas sociales presentes en el mundo social de las autoras.

Published: December 2021

Objective. To conduct a morphometric analysis of the soleus muscle of rats after moderate spinal cord contusion injury.

Material and Methods. Experiments were performed on female Wistar rats aged 8–12 months, weighing 270–320 g. Animals of the experimental group (n = 25) underwent laminectomy at the T9 level under general anesthesia and modeling of spinal contusion injury of moderate severity. Intact rats constituted the control group (n = 10). Euthanasia was performed on the 5th, 15th, 30th, 60th, 90th, and 180th days of the experiment. Paraffin sections were stained with hematoxylin-eosin and Masson, the diameters of muscle fibers were determined by computer morphometry, and histograms of their distribution were obtained.

Results. In the soleus muscle, the signs of reversible reparative processes prevailed in response to neurotrophic damage. It was evidenced by a local increase in the diversity of myocyte diameters and the loss of polygonality of their profiles, focal destruction of muscle fibers, activation of the connective tissue component, disorganization of some intramuscular nerve conductors, and vascular fibrosis of perimysium. Nevertheless, the histostructure of an intact muscle prevailed in the course of the experiment, which was confirmed by the data of morphometric analysis. All histograms of the distribution of the muscle fiber diameters are unimodal with a mode in the range of 30–41 μm. On the 180th day, the maximum myocyte diameters in the histogram of the left limb muscle belonged to the range of 21–30 μm, which was typical for histograms in the intact group.

Conclusion. The nature of the plastic reorganization of the soleus muscle when neurotrophic control is impaired indicates compensatory regeneration of muscle tissue by the type of restitution, which opens up the possibility of predicting the rehabilitation period. It is advisable to take this into account when developing medical and social programs and therapeutic measures, where the most important role is played by superficial neuromuscular and functional electrical stimulation.
X-ray and CT scan predictors of damage to the posterior ligamentous complex in fractures of the vertebral bodies of the thoracolumbar junction: systematic review and meta-analysis
Authors: Afaunov Asker Alievich , Chaikin Nikita Sergeyevich , Basankin Igor Vadimovich , Takhmazyan Karapet Karapetovich
Published: December 2021

Objective of the review was to identify, basing on literature data, the most reliable X-ray and CT signs of damage to the posterior ligamentous complex (PLC) in fractures of the vertebral bodies of the thoracolumbar junction, initially interpreted as type A according to the AOSpine classification. The systematic review was carried out according to the recommendations of PRISMA. The search in PubMed, MEDLINE and Cochrane Library databases revealed 491 articles on relevant issues. Once the inclusion and exclusion criteria have been met, 7 original articles from peer-reviewed scientific journals for the last 10 years were selected for a systematic review, 6 of which were included in the meta-analysis. In all articles, the authors identified two groups of patients: with and without damage to the PLC. The PLC damages were confirmed by MRI and intraoperatively. Radiographic and CT spondylometric parameters were identified, which had statistically significant differences between the groups. To determine predictors of PLC damage, the values of these parameters were subjected to regression analysis. This was followed by a meta-analysis of random and fixed effects models depending on the homogeneity of the data. Statistical heterogeneity was assessed using the X-square test with the null hypothesis of the absence of significant differences in all studies, as well as the heterogeneity index – I2. For the graphical display of the results, forest plots were built. Local kyphosis angle >25°, Cobb angle >16° and difference between interspinous distances >2.54 mm are CT scan predictors of PLC damage. The parameters characterizing the interspinous relationship were studied in no more than two studies, but at the same time they always had statistically significant differences between the groups with and without PLC injuries, therefore, they cannot be ignored during diagnosis. Anterior/posterior vertebral height ratio, anterior vertebral height ratio, sagittal index and suprajacent/subjacent parameters are not the predictors of PLC damage.

Published: December 2021

Objective. To assess the significance of clinical factors of extramedullary tumors and new methods of their resection as potential predictors of their recurrence and continued growth.

Material and Methods. The long-term results of removal of primary extramedullary tumors in 412 patients operated on in 1998–2014 were analyzed comparing the use of standard methods of microsurgical technique for tumor removal (277 patients) and of those with additional use of neodymium laser radiation (135 patients).

Results. The use of laser technologies for resection of extramedullary tumors can significantly reduce the number of their recurrences and continued growth, along with other clinical factors is a significant prognostic indicator in determining the nature of the disease course and can be a predictor of their occurrence. The most reliable clinical factors determining the prognosis of a decrease in the incidence of recurrences and continued growth when using laser techniques of surgical resection were repeated operations (p = 0.002), the presence of ependymomas of the cone and cauda equina (p = 0.017), operations for primary tumors in the thoracic spine (p = 0.039) and extramedullary tumors with Grade I anaplasia (p = 0.007). An increase in the number of these conditions was associated with operations on the cervical spine (p = 0.027), the presence of a tumor with Grade II anaplasia (p = 0.007), and a primary extramedullary tumor involving more than three vertebrae (p = 0.017).

Conclusion. The use of the laser is indicated for reoperations when removing neoplasms, that have arisen as a result of recurrence or continued growth of extramedullary tumors of any level and length after removal of primary neoplasms with a Grade I malignancy confirmed by intraoperative cytological examination involving no more than three vertebrae in the thoracic, lumbar and sacral spine and during resection of ependymomas with extramedullary growth.

Published: December 2021

Drowsiness is the main cause of road accidents and it leads to severe physical injury, death, and significant economic losses. To monitor driver drowsiness various methods like Behaviour measures, Vehicle measures, Physiological measures and Hybrid measures have been used in previous research. This paper mainly focuses on physiological methods to predict the driver’s drowsiness. Several physiological methods are used to predict drowsiness. Among those methods, Electroencephalography is one of the non-invasive physiological methods to measure the brain activity of the subject. EEG brain signal extracted from the human scalp is analysed with various features and used for various health application like predicting drowsiness, fatigue etc. The main objective of the proposed system is to early predict the driver drowsiness with high accuracy so that we have divided our work into two steps. The first step is to collect the publicly available dataset of EEG based Eye state as (Eye open and Eye closed) where the signal acquisition process was done from Emotiv EEG Neuroheadset (14 electrodes) and analysed various feature engineering techniques and statistical techniques. The second step was applied with the machine learning classification model as K-NN and performance-based predicting models are used. In the Existing System, they used various machine learning classification models like K-NN and SVM for EEG Eye state classification and produced results around 80% -97%. Compared to the Existing system our proposed method produced better classification models for predicting driver drowsiness using different Feature engineering process and classification models as K-NN produced 98% of accuracy.

Published: December 2021

The heart disease detection and classification using the cost-effective tool electrocardiogram (ECG) becomes interesting research considering smart healthcare applications. Automation, accuracy, and robustness are vital demands for an ECG-based heart disease prediction system. Deep learning brings automation to the applications like Computer-Aided Diagnosis (CAD) systems with accuracy improvement compromising robustness. We propose the novel ECG-based heart disease prediction system using the hybrid mechanism to satisfy the automation, accuracy, and robustness requirements. We design the model via the steps of pre-processing, hybrid features formation, and classification. The ECG pre-processing is aiming at suppressing the baseline and powerline interference without loss of heartbeats. We propose a hybrid mechanism that consists of handcrafted and automatic Convolutional Neural Network (CNN) lightweight features for efficient classification. The hybrid feature vector is fed to the deep learning classifier Long Term Short Memory (LSTM) sequentially to predict the disease. The simulation results show that the proposed model reduces the diagnosis errors and time compare to state-of-art methods.

Published: December 2021

The aim of this study was to study the impact of crop load on the yield and grape quality of ‘Merlot’ and ‘Vranac’ (Vitis vinifera L.) in Trebinje vineyard. The crop load levels studied in this trial were 9 buds (V1) and 12 buds (V2) per vine at each variety trained on Lenz-Moser bilateral cordon system. The impact was determined by measurements of yield per vine and grape quality characterized by the contents of total soluble solids, titratable acidity, total phenolics, total flavonoids and by total antioxidant capacity. The measured parameters of grape quality of ‘Merlot’ and ‘Vranac’ were not influenced significantly by crop load levels. V2, compared to the V1, showed the potential for increasing grape yield only for Merlot variety under experimental conditions. The results of this study also showed a positive correlation between total phenolics/flavonoids and total antioxidant capacity of grape berries in both varieties, regardless of crop loads applied.

Fusarium graminearum fungus cause significant loss in maize (Zea mays L.) and other cereal crops all over the world. The usage of chemical agents cause severe environmental problems. Bacillus species and other plant growth-promoting bacteria (PGPR) play key role in biopesticide development. A wide range of environmentally safe antimicrobial agents are already being manufactured. The current investigation was focused on exploring the antifungal activity of Bacillus thuringiensis lipopeptide surfactin against fungal phytopathogen Fusarium graminearum. B. thuringensis was isolated from the rhizosphere of maize crop and cultivated to produce lipopeptides. Surfactin was identified by high-performance liquid chromatography (HPLC) from the extract at 210 nm, retention time 3-5 minutes and the obtained peaks area was 3.990. The growth of F. graminearum was successfully inhibited by surfactin at different concentrations. Among these, 80 % concentration showed the highest zone of inhibition in comparison to 60 %, 40 % and 20 % concentrations (p < 0.005), respectively. The current study concludes B. thuringensis lipopeptide surfactin has a high potential to inhibit the growth of F. graminearum.

Objectives

Lifestyle changes have led to an increase in the prevalence of hypertension in Chinese children and adolescents. The aim of this study was to analyze the prevalence of hypertension and its association with overweight and obesity among students aged 6–17 years in Suzhou. This retrospective analysis included physical examination data of primary and junior high school students in Suzhou Industrial Park from 2016 to 2019.

Methods

Elevated blood pressure and hypertension were defined using blood pressure criteria appropriate for age, sex, and height percentile. Overweight and obesity were defined using the 2007 diagnostic criteria proposed by the World Health Organization for school-age children. Logistic regression analysis was used to evaluate the association between hypertension and overweight and obesity.

Results

A total of 128,113 students were included. The prevalence of elevated BP and hypertension was 9.92% and 13.56%, respectively. The incidence of high blood pressure was higher in boys than in girls and increased with an increase in body mass index (BMI). The prevalence of hypertension in obese boys and girls (27.07% and 27.49%, respectively) was 2.3-fold and 2.8-fold higher than that in normal-weight boys and girls (11.58% and 9.83%, respectively).

Conclusions

Blood pressure was positively correlated with BMI, and the risk of high blood pressure due to overweight/obesity was 10.44%. Overweight and obesity significantly increased the risk of hypertension in students aged 6–17 years in Suzhou. Targeted weight-loss programs during childhood and adolescence may reduce the risk of hypertension in adulthood.
Sustainability Assessment of Electricity Supply Chain via Resource Waste Reduction and Pollution Emissions Management: A Case Study of the Power Industry
Authors: Pouralizadeh Mojgan
Published: December 2021

The energy and power industries are one of the most important economic sectors, essential in creating value-added economic growth in any society. The waste of energy resources and environmental issues in the energy and power plant sectors have created various challenges for the power industry. Managing existing capacities and reducing environmentally harmful effects result in system efficiency enhancement and wasted energy returns to the natural cycle in electricity supply chain divisions. This study aims to determine divisions of an electricity supply chain as resource allocation handling, providing harmful emissions abatement (e.g., carbon dioxide and greenhouse gases) and waste energy mitigation. The proposed intermediate approach measures the unified inefficiency score of each production factor and determines the level of total unified inefficiency from the average of the sum of these inefficiency scores. Indeed, the proposed intermediate approach distinguishes influential supply chain divisions from the uninfluential ones to sources utilization management for abatement of significant flare and greenhouse gases and wasted energy in energy and power plant sectors, as well as transmission and distribution lines. The current paper introduces intermediate approaches for sustainability evaluation of the electricity supply chain based on data envelopment analysis models. The proposed approach evaluates the potential of supply chain divisions to reduce undesirable outputs. The intermediate approach, under managerial disposability, enables us to determine regions of the supply chain with the necessary preparation to confront harmful emissions and wasted energy. One empirical implication has been obtained from model performance in the electricity supply chain. Findings suggested that the oil field, power plant, and transmission line divisions, as well as industrial consumers, have adequate potential for pollution emissions abatement and energy loss prevention as the increase of inputs provides more outputs. Moreover, these divisions are efficient in 10 supply chains. The implications of the results, including the fact that the increase of inputs provides desirable output increments and productivity enhancement in the oil field, power plant sections, and industrial consumers, have been considered.

This paper presents a metaheuristic method, namely Equilibrium Optimizer (EO) to solve the economic dispatch (ED) problem. The main objective function to be achieved is to minimize the total fuel costs of all generating units to meet the total load demand and to satisfy various operating constraints. Three case studies are used to test the effectiveness of the EO method in solving ED problems, they are three generators case, six generators case, and fifteen generators case. The simulation of solving ED problems using the EO method is implemented using MATLAB software and is carried out 30 times for each case study. The results of EO method are compared with Particle Swarm Optimization (PSO), Grey Wolf Optimizer (GWO), and Whale Optimization Algorithm (WOA) methods. The simulation results show that the EO method can solve the ED problem more optimal than all other comparison methods for all the case studies by producing the minimum total fuel costs.

Process industries such as oil refineries, petrochemical plants, and power plants require a human-machine interface system to monitor continuously. The operator usually carries out monitoring via a human-machine interface. However, it is difficult to know the condition of process equipment in real-time. The implementation of augmented reality allows engineers to visualize process equipment in real-time when conducting field inspections. The implementation of augmented reality at the human-machine interface to the fluid catalytic cracking process in an oil refinery is discussed in this paper. The design was started by developing a three-dimensional process equipment model using Autodesk Inventor. The result of the three-dimensional model then using Unity 3D software connected to the Vuforia Engine was implemented on a gadget into an augmented reality application. Data communication performance analysis was carried out using inferential statistics methods to test variations in service quality at levels 0, 1, and 2. The result of the Tukey test showed that the communication network latency value in level 2 was significantly higher than levels 0 and 1, which was 0.704±0.108 seconds. These results indicate that augmented reality can be implemented on human-machine interfaces by ensuring the quality of data communication services using Message Queue Telemetry Transport (MQTT) protocol at levels 0 or 1.

Self balancing robot is a two-wheeled robot that only has two fulcrums so that this robot is an unbalanced system. Therefore, a control system that can maintain the stability of the robot is needed so that the robot can keep in standing position. This study aims to design a self-balancing robot and its control system which improves the robot's performance against the maximum angle of disturbance that can be overcome. The control system used is based on fuzzy logic with 9 membership functions and 81 rules. The control system is applied to the ESP-32 microcontroller with the MPU-6050 sensor as a feedback position of the robot and DC motor as an actuator. Complementary filters are added to the MPU-6050 sensor readings to reduce noise to obtain better robotic tilt angle readings. The improvement of this research compared to previous research based on fuzzy is the addition of the number of membership functions from 7 to 9 and the embedding of a complementary filter on the MPU-6050 sensor output reading. The result shows that the designed self balancing robot which has dimensions of 10cm x 18cm x 14.5cm can cope with the maximum disturbance angle up to 17.5⁰.
