Un matadero perpetuo”: Distopías en la narrativa de Erich Rosenrauch
Authors: Sepúlveda Villa Gloria
Published: March 2023

Erich Rosenrauch Vogëlfanger (Viena, 1931–Inglaterra, 1978) publicó entre 1974 y 1978 cinco novelas que operan sobre estructuras distópicas. El caos es un elemento intrínseco en Clima de optimismo (1974), Salvaguardia (1974), En un país lejano (1976), Muertos útiles (1977) y La burra (1978). La distopía se expresa bajo cinco perspectivas: dictadores que ejercen el totalitarismo ineptamente, o bien, narrando la guerra continua, el fin de las instituciones, la negatividad de la explosión demográfica y la utilidad de los muertos. El escritor da un paso más allá cuando propone una distopía sexual en La burra. Las novelas abordan la distopía que recorta distintos territorios ficticios: Osmania, Estolandia y Cantonia y el Teatro Afrodita. La distopía de Rosenrauch emerge del abuso de poder, de los medios masivos de comunicación que automatizan a la sociedad y la ineptitud de las autoridades que simulan la democracia
Autobiografía y cruce en Las malas de Camila Sosa Villada
Authors: Venturini Ximena
Published: March 2023

En el presente artículo se estudiará el uso del yo autobiográfico en la novela Las malas (2019) de la escritora argentina Camila Sosa Villada. A partir del relato de su infancia y adolescencia, se analizará la forma en que la protagonista se nombra así misma en el relato, haciendo de su novela un retrato identitario de su vida como mujer trans.
Además, partiendo de los postulados que Paul B. Preciado presenta en Un apartamento en Urano (2019) sobre el cuerpo trans como un espacio de mezcla, se analizará el yo que se presenta en la novela entendido como una multiplicidad de voces que operan en aquello que Preciado denomina “el cruce”: el cuerpo trans cruza una frontera política y que lo relaciona con la comunidad que lo acepta o rechaza.

Arte y contexto social
Authors: Albar Mansoa Javier
Published: March 2023

El papel del arte y de los artistas en el contexto cultural y social ha sido una de las cuestiones más tratadas y debatidas a lo largo de la historia, y desde distintos ámbitos teóricos y prácticos de las artes, las humanidades y las ciencias sociales se han aportado diferentes visiones sobre la materia. Sin embargo, en todos los casos, se ha coincidido en la relevancia que tienen obras, procesos y agentes artísticos en el tejido cultural de los distintos contextos, y en cómo las artes han proporcionado un campo de conocimiento, de comunicación y de experimentación fundamental para las sociedades.  

En el momento actual, el arte se entiende como un factor que, además de cumplir las funciones estéticas que tradicionalmente se le han atribuido, puede y debe aportar otras contribuciones a la sociedad. En este congreso se presentarán investigaciones que versan sobre esta temática desde diversas perspectivas, con objeto de proporcionar una reflexión colectiva y actual sobre cuáles pueden ser las relaciones entre las artes y el contexto social en la actualidad. Para ello, se contará con diversas mesas en las que tratar y debatir sobre algunos puntos específicos. 

En el caso de la salud se trabajará, por ejemplo, sobre cómo estas contribuciones del arte se extienden a determinados contextos en los que, aunque ya tenía un papel destacado, ahora debe ser aún más relevante, sin pretender sustituir a agentes o instituciones que desempeñan tareas de apoyo. El arte no puede curar, ni salvar el mundo, pero puede contribuir a mejorar las condiciones de la gente que se encuentra en situaciones difíciles y ayudarles a superar dichas situaciones. La labor de los artistas en estos contextos y con determinados colectivos (niños, personas mayores, en hospitales, centros sanitarios,…) es un valor en alza, que requiere personas capaces de compaginar los conocimientos y la práctica artística con la sensibilidad para interactuar con ellos, y que abre un campo lleno de posibilidades en el ámbito del arte y de la educación artística.

Authors: Dawusu Umar Jamaluddin , Baffa Sani Suraja , Muhammad Adam Uba
Published: March 2023

The widespread use of antibiotics both inside and outside of medicine is playing a significant role in the emergence of resistant bacteria. The study was aimed to determine the antibiotic sensitivity patterns of Staphylococcus aureus and Escherichia coli isolated from Urinary Tract Infected (UTI) patients. Antibiotic susceptibility patterns of the bacterial isolates were determined using modified Kirby Bauer method. The susceptibility of antibiotic against S. aureus showed that most of the isolates were resistant to more than 3 antibiotics. Most of the isolates were sensitive to gentamicin, ofloxacin, Septrin and Augmentin. However, the isolates were more resistant to streptomycin, Nalidixic acid and levofloxacin. The susceptibility pattern of S. aureus against the antibiotics showed that 14 out of the 20 isolates were multi drug resistant. For E. coli, result showed that most of the isolates were resistant to more than 3 antibiotics. Most of the isolates were sensitive to Levofloxacin, ofloxacin, Streptomycin and gentamicin. However, the isolates were more resistant to Ceporex, Augmentin and ampicillin and 14 out of the 20 isolates were multi drug resistant. It is concluded that the bacteria isolated from UTI patients are mostly resistance to some classes of antibiotics.

So Close: Measuring Social Distance in Virtual Relationships
Authors: Ramos Ritta Dianne , Pasia Dolorosa
Published: March 2023

The objective of the study is to create a measure for social distance in virtual relationships developed through online interaction. The researchers patterned their scale from the Bogardus Social Distance Scale, incorporating the recommendations of Michael Heraghty (2002). The researchers used quantitative and qualitative methods in determining the concepts and variables that could be included in their social distance scale for virtual relationships. Selection of informants and respondents was done using the purposive method of non-probability sampling. Focus group discussions and online interviews were first conducted to determine the important variables and appropriate arrangement of items in the social distance scale. Subsequently, social distances toward different kinds of people and the validity and reliability of the variables in the scale were examined through surveys, the primary quantitative research method of this study. Generally, survey results showed that respondents were most likely to interact with females, people within their age bracket, and people residing within their city or municipality. In contrast, they were unlikely to pursue any interaction with gays and lesbians. Survey findings also showed that online interactions start with including a person in someone’s messenger account; conversations – even those about non-personal topics – can only take place after the respondents have added a person in their messenger list.

Предметом исследования является неоднородное, линейное дифференциальное уравнение в частных производных четвертого порядка с двумя независимыми переменными. Целью исследования является нахождение решения удовлетворяющих как начальным, так и однородным краевым условиям первого рода. Интегральные, интегро-дифференциальные уравнения можно встретить во всех областях науки, например уравнение переноса, возникающее в процессах замедления нейтронов, играющее большую роль в современной физике. Мы знаем, что колебания тонкой проволоки можно выразить отдельными дифференциальными уравнениями второго порядка. Если вместо проволоки рассматривать тонкую сплошную балку (тонкий молоток), то процесс ее колебаний выражается дифференциальными уравнениями четвертого порядка. Такие проблемы возникают при проектировании тяжелой техники. Для построения решения была применена формула Дирихле для двойного интеграла, вследствие которого получаются интегральные уравнения Вольтерра с тремя неизвестными. Формула Дирихле была использована для решения задачи Абеля. В заключении была доказана основная теорема о существовании решения обратной задачи, удовлетворяющих выше указанным условиям.

Authors: Alam Khan Dr Ismail , Alam Dr Aziza , Durrani Dr.Mushyyada , Iqbal Dr Nayab , Akhtar Dr. Ambreen , Gul Dr. Rubeena
Published: March 2023

Objective: To explore their perception how patient safety is being addressed in undergraduate and post graduate medical curriculum

 

Methods: This was descriptive survey; using the universal sampling technique a questionnaire based survey was conducted with 80 post graduate residentss in two selected tertiary care hospitals to determine their attitude towards the patient’s safety measures. A tested questionnaire was used to collected data. Descriptive statistics were obtained by using SPSS software version 20.

 

Results: out of total 80 participants 16% were female and 84% were male having clinical experience ranged from 2-5 years. Regarding the attitude varying responses were reported.  17(21.3%) were strongly agreed that Making errors in medicine is inevitable, similarly 52(65%) were also strongly agreed that consciousness after encountering with error could reduce the occurrence. 29(36.3%) were strongly agreed that Competent physicians do not make medical errors, regarding morality 55(68.8%) were strongly agrees the patient safety is our moral responsibility. however they indicated that there is lack of proper reporting system which act as barrier.  Less than half of the participants were in support of routinely report medical errors. 58(72.5%) reported with disagreement regarding reporting the medical error. The document review shows that there is no specific slot delegated to the patient safety measure in the curriculum of Postgraduate as well as undergraduate medical curriculum however they has addressed the topic indirectly to some extent.

 

Conclusion: It is concluded that the participants (Trainees medical officers) had positive attitude towards the patient safety. Although they are aware about patient safety however has varying interpretations depending upon the case and situation. The medical errors being inevitable aspects is broadly associated with; the human factor, system and management factors which have further multi-facets linkages, contributing to medical error.  The main reason for the patient safety concerns is due to the gap between what WHO recommended about patient safety and the curricular contents of undergraduate and postgraduate medical studies in Pakistan

Objective: This study aimed to determine the effects of Liraglutide on glycosylated hemoglobin (HbA1c) and body weight in patients with type 2 diabetes.
Material and Methods: A prospective observational study was conducted in a private tertiary healthcare setting. A total of 58 adult patients with T2DM using oral anti-diabetic agents with or without insulin were enrolled in the study from November 2020 to April 2022. Liraglutide was administered at a dose of 0.6 mg/day which was raised to 1.2 mg/day after 1 week and later to 1.8 mg/day depending upon patient preferences and tolerability. Patients were assessed for changes in their body weight, fasting blood glucose (FBG) level, random blood glucose (RBG) level, and HbA1c at the 1st and 2nd follow-up visits of the 8th and 16th week, respectively.
Results: At the 16th week, the mean weight was 100.78±17.56 vs 102.74±17.26 and 104.11±17.95 at the 8th week and baseline visit, revealing a significant difference across three-time points [F(1.4, 36.45)=8.57, p=0.003]. A post hoc pairwise analysis showed that weight significantly decreased from baseline and 16th-week follow-up visits (p=0.011). Similarly, a significant decrease was observed in mean HbA1c across three-time points [F (2, 39.40) =8.81, p=0.001]. Mean HbA1c at 16th week was 6.61±1.13% vs 8.09±1.43% at baseline (P = 0.001). No significant reduction in FBG, RBG, blood pressure, and serum lipid profile were observed. Moreover, no major side effects occurred in any patient.
Conclusion: Liraglutide is an effective and well-tolerable drug in improving glycemic control, causing significant weight loss in the study population when used as a monotherapy or in combination therapy.

Published: March 2023

The use of the Global Positioning System (GPS) as a fast and efficient alternative in the geodetic network measurements has become a common practice worldwide. The advantages of using the GPS technique compared to the traditional surveying methods are based on accuracy, time and cost. In this study, the static-mode of GPS measurement technique has been utilized to establish a precise geodetic network in Khartoum State. The network was referenced to a single control station that is related to the International Terrestrial Reference Frame (ITRF 2005). A number of six points have been constructed and observed around Khartoum State. In particular, seven observation sessions were conducted that gave an over determined system. The least-squares method was used in the adjustment of the GPS network. Two methods were utilized for the adjustment, namely, the parametric and the condition equation methods. The most probable values of the coordinates of the newly-established points were computed from both methods and they were found to be identical. The average standard deviation of the X, Y, and Z coordinates are ±1.36 cm, ±1.12 cm, & ±0.69 cm respectively.

Authors: A. A. Alnoor Jaafar , B. A. N. Mustafa Amin
Published: March 2023

This paper shows the difference in video quality between two compressed videos using H.264 AVC (Advanced Video Coding) and H.265 HEVC (High Efficiency Video Coding) encoders. To evaluate video completely it should be prepared video files that have a variety of bit rates and content. There are many video quality assessment methods. We can divide the min to subjective and objective methods. Subjective are conducted by a human perception and objective are conducted by a computer software which is calculating the video quality. All of these methods have theirs advantages and disadvantages. To generate compressed videos from the original video FFmpeg (Fast Forward-moving picture experts group) converter has been used. MSU-VQMT (Moscow State University’s Video Quality Measure- mentTool) was used to perform comparative objective analysis of video quality. Delta, MSE (mean square Error), MSAD (Mean Sum of Absolute Difference), PSNR (Peak Signal-to-Noise Ratio), and SSIM (Structural Similarity Index Measure) metrics were measured. The result from FFmpeg shows that the size of the compressed video using the H.265 codec has been decreased by 50% compared to the compressed video using the H.264 codec. The comparison of metrics shows that delta, MSAD, PSNR, and SSIM values of H.265 encoded video was decreased, while Delta and MSE value was increased compared to H.264 encoded Video. That’s mean the overall video quality was decreased but the video size was enhanced.
A Comparative Study of Artificial Intelligence Algorithms Used for an Accurate Image Geometric Dimensions Recognition
Authors: Mohamed Hamoud Kaid Mahmoud , Mohamed Ahmed Mahmoud Muawia
Published: March 2023

The process of distinguishing objects in digital images and recognizing them is a basic process in AI, in order to distinguish the object and determine its features. It has many uses in various engineering and medical fields. There is a great difficulty in recognizing digital images and distinguishing objects in them. This paper discusses some basic artificial intelligence techniques based on the geometric dimensions of the object in the image in order to recognize these objects and distinguish them from the background of the image. Where there is great difficulty in separating the object from its background, this paper presents the most accurate methods of programmatic application using Matlab environment to identify components in the image, its distinction, and its characteristics. The paper provides a comparison between these AI methods and chooses the most accurate one. AI recognition methods use various algorithms including algorithms based on color density and algorithms that depend on geometric dimensions such as Hue moment algorithms, Haralik features algorithms, and Zernike moment algorithms. In this paper these algorithms were applied to a group of images to extract the features of the object and the best one will be chosen with the aid of Matlab. The most accurate recognition process is chosen through building a digital library that contains many pictures and training the program on these images to recognize and distinguish the object in the image.

Authors: Al-Ameri Wahbi , Elhassan Ahmed , Maher Ragaei
Published: March 2023

Although various techniques exist for remediation of wastewater, electrochemical technology and electrochemical advanced oxidation processes are the most promising and innovating methods for destroying and eliminating a broad-range of organic and inorganic contaminants presented in the produced water effluents. This study presents integrated electrochemical treatment techniques including electrocoagulation process, electrooxidation process and electro-Fenton process for a real produced water, supplied by an oil company. The electrocoagulation method was conducted by iron and aluminum electrodes, electrooxidation method by graphite electrodes and the electro-Fenton method by iron and graphite electrodes. The experiments were performed in the same electrolytic batch cell with the same spacing between electrodes and electrode surface. The feasibility of treatment processes was monitored by the removal of total organic carbon (TOC) and chemical oxygen demand (COD).As a result of the study, the most efficient technology was the electrooxidation process where the removal efficiencies of TOC and COD were 93.5 % and 94 %, respectively. Additionally, electro-Fenton process led to higher removal efficiencies reaching 85 % and 87 % for TOC and COD, respectively. The electrocoagulation treatment of produced water by using iron and aluminum electrodes was moderately efficient for removal of TOC. However, it was inefficient for removal of COD. Furthermore, electrocoagulation remediation was proved to be an effective method for removal of inorganic species such as calcium, magnesium and sulfate. It can be concluded that electrochemical methods could be used for effective produced water treatment where it can be safely disposed of or effectively reused for injection and irrigation.

There is a need to control air temperature and humidity in humid regions, especially when fresh air is demanded. This study investigates the performance of a hybrid liquid desiccant (LD) air-conditioning system with a direct expansion (DX) evaporative cooler. Temperature, relative humidity, and power consumption were measured and reported using a wireless data-logging system at the air conditioning unit's key locations. The results showed that the hybrid unit reached a 34 % saving in the cooling load. In addition, the air hybrid liquid desiccant air-conditioning system with the direct expansion evaporative cooler saved about 32% in power consumption, compared to an uncooled desiccant air conditioning system that saved 23%.

Published: March 2023

This paper implements object video tracking system that represents object location in subsequent video frames. A closed-circuit television (CCTV) camera mounted on a rotating system is used for capturing video while the object of interest always kept at the centre of the screen. Three tracking algorithms were selected and implemented: template matching, contour matching and optical flow. Measures of their accuracy and speed were taken for comparison. The software was implemented in a personal computer with C# programming language, with the aid of EmguCV which is a wrapper for OpenCV, a famous image processing library. The system implemented for this study is able to successfully track a rigid body, discernible from the background objects with size up to 400×300 pixel for the Phase Alternate Line (PAL) system of 720×576 pixel frame size. Tracking was stable even with the existence of rotation and scaling. Some faults were observed when occlusion was present or when the target was moving with a speed faster than that of the rotation system of 30 degrees/s horizontal and 15 degrees/s vertical.

Published: March 2023

The main objective of this paper is to assess the quality of drinking water at the out skirts of Khartoum State. The objectives include studying the effects of practices employed by the inhabitants of Al-Hella Al-Jadeeda in handling, transporting and storing water. In addition to statistical analysis of data collected through questionnaires, samples from different sources and locations of wells, tanks, carro carts and drinking water containers, were collected and examined physically, chemically and microbiologically. The results revealed that, the water is physically and chemically acceptable for human consumption except for some doubts in its lead content. The lead content was found to be varied between 0.03 to 0.667 mg/L, which indicates a quantity far above the maximum allowable limits. Tests conducted on microbiological quality of water showed that water samples, were highly contaminated with coliform bacteria, which implies that fecal contamination is evident. It could be concluded that the pollution found is due to poor environmental sanitation awareness and carelessness of people on their personal hygiene. The study recommended that a network distribution system should be established in the area. Meanwhile, traditional drinking water carriers and distributors must be periodically cleaned, regularly disinfected with chlorine to remove any public health hazards. It is also recommended to introduce low-cost technologies such as sand purification systems in addition to the enhancement of awareness on the health hazards of polluted water.

The aim of this study is to simulate a Fluid Catalytic Cracking (FCC) Regenerator, of a local refinery, using the Fluent Ansys.13 program and subsequently to investigate the impact of the change in geometry on the unit’s performance. Three different geometrical models of FCC Regenerator were simulated. The Solid Works program was used to build up the computational domain and the commercial CFD code Ansys-Fluent 13 was used for meshing, models setup and solving. Three cases were examined: base case with a single air inlet, case one with five air inlets, and case two with five air inlets, however with the catalyst inlet axis raised by 100%. The results showed that the carbon solid mass content (used to represent the coke) decreases from 0.39 to 0.23 in the base case and to 0.12 in case one and to 0.19 in case two for the regenerated catalyst. Case one resulted in a decrease in carbon content by 100%, with a carbon monoxide emission of 10ppm (the base case at a value of 200ppm) which increased in case two to 100ppm. Furthermore the impact of air mass flow rate in case one (best case) was investigated starting with a mass flow rate of 29.5kg/s. The flow rate was further increased by 100% and 200% which resulted in a carbon mass content of 0.092 and 0.08 respectively.

Published: March 2023

Multiple injuries and fatalities occur during confined space entry work more than any other type of work performed in all developed countries. This research aimed at evaluating employee's awareness of confined spaces basic concepts and work hazards, and to generally assess the entry program used to access these confined spaces. The data were collected from a random sample of factories and industries in Khartoum north industrial area. A questionnaire was the instrument used to collect the data. The data were analyzed using standard Statistical Package for the Social Sciences (SPSS). The results demonstrated lack of employee's awareness regarding the concept of confined spaces and hazards of working. It also shows failure of (80%) of workplaces to conduct confined space training, ensure supervision and provide procedures reinforcing the need for a comprehensive confined space safety program. It also demonstrated little evidence of a safe system of work in many of the cases. Over (82%) of the confined spaces were permitted to be entered without pre-entry hazards identification. In addition no atmospheric gases monitoring before or during entry (0%) since over (80%) of spaces expected to contain atmospheric hazards depending on confined space location, construction, condition, and work to be performed. also no effective nor adequate emergency rescue procedures were hold. The results showed that the most important reasons for confined spaces accidents and fatalities were lack of employees' perception of hazards from working in confined spaces, and scarcity of designing appropriate preventive measures and entry written programs by companies. Accordingly, the study will help in putting the companies comply with their own procedures and practices, and to maintain the safety of the employees.

Published: March 2023

This paper presents the superiority of data mining techniques in predicting the amount of power generated by thermal power plants, over the traditional approaches that use thermodynamic laws or the power plant manufacturer’s guides. The paper first compares between amount of power calculated using thermodynamic laws, and the amount of power predicted using manufacturers’ guides with the actual power generated. Then prediction model was built to predict the amount of generated power using the controllable parameters at turbine inlet. Models were evaluated using separate test sets, or cross validation in case of small sets. The values predicted by this model is then compared with actual and other predicted values to prove that data mining tool is most accurate than traditional methods.

Published: March 2023

Many types of grids are developed to address the fast growing demand such as smart grid and Microgrid. The main objectives of this paper were to explore the implementation of Microgrid in a fish farm, to show the benefit of adding a renewable source; the photovoltaic system. The Micro-grid consisted of old Indian diesel pumps- which caused all types of pollution diesel spill engine oil spill, noise and utility supply. Photovoltaic system is added after a catastrophic accident by contamination a fish pond by mix of diesel and engine oil killing tens of thousands of fishes. The Photovoltaic system panel was connected directly to a DC centrifugal solar pump. The solar pump produced an average flow rate of 0.0073 m3/s (210.65 m3 per day). The data sheet showed that the selected pump should produce 200 m3 per day, and this means that the design performance and experiment results are in close agreement. Furthermore, this grid shows a good actual experience of using solar pump for fish ponds as replacement of the traditional diesel-based method.

Published: March 2023

This paper proposes a novel simple staircase modulation to obtain reasonable performance of an output voltage for a cascaded HBridgemultilevel inverter. The motivation of the proposed algorithm is that the inverter phase voltage intersects with an original sinusoidalwaveform at equal points in the y-axis. This modulation technique can calculate the independent switching angles more simply than thetraditional method, which employed Fourier’s series analysis, and can be applied to all kinds of multilevel inverters. In this paper, for the sake of validation, the technique was applied to a cascaded H-bridge inverter with unequal DC sources. Then, it was applied to the seventh, ninth, eleventh, and twenty-seventh levels of the multilevel inverter. In addition, pulse width modulation techniques used in this type of multilevel inverter are complicated. The PSIM software program was used for all simulation examples, and its results are consistent with the experimental results.

Background: Pressure is a localized injury to the skin and underlying tissue usually over a bony prominence, as a result of pressure, or pressure contributing to shear. Objective: The main objective was to determine the prevalence of pressure ulcers in the patients of Ibn e Sina hospital Multan and to determine the risk factors contributing to pressure ulcers by using Braden Scale. Methodology: It was a cross-sectional observational study conducted on 246 patients of Ibn e Sina hospital Multan. During the 6 months of the study, patients were interviewed regarding their demographics and risk factors for pressure ulcers according to the Braden scale. Spss21 was used to analyze the data. Results: Out of 246 patients, 74.8% of male patients had pressure ulcers. The patients were from 25 to 85 years old. The pressure ulcers were more frequent among the 45 to 65 years age group (i.e., 44.7%) and married patients (95.5%). Among 246 patients only 4.5% patients were at extra high risk and most of the patients were at low risk (69.5%) by using the Braden scale. This data will help physicians, researchers, and policymakers in Pakistan and other nations advocate for the needs of pressure ulcer patients. Conclusion: According to this study pressure ulcers were more frequent in male married patients of the middle age group. Most of the patients were at low risk of developing pressure ulcers on the Braden Scale.
