Digital twin and contact analysis of ultra-long distance coiled tubing operation structures
Authors: Wei Wenlan , Qu Hao , Cheng Jiarui , Wang Wenyuan , Wang Maliang
Published: January 2023

Background: Coiled tubing operation is a high-quality operation method that considers both cost and efficiency in current oil and gas well operations. There is a significant difference between the calculation and prediction before operation and the actual operation. The reason is that the complex wellbore trajectory makes it difficult to evaluate the contact state between coiled tubing and wellbore, resulting in a significant error in the pipe string mechanics calculation and analysis.

Methods: Aiming at the contact problem between coiled tubing and wellbore in the process of coiled tubing operation, the digital twin unit of coiled tubing and wellbore is established in this study. By constructing a feedback correction collision contact algorithm, the contact state of coiled tubing and casing under different three-dimensional trajectory models was simulated.

Results: The research results show that the digital twin coiled tubing and contact algorithm can effectively predict the contact state of coiled tubing operations; the verification model shows that the contact algorithm can accurately analyze the contact state of different well trajectories.

Conclusions: The digital twin of the coiled tubing operation structure and its contact algorithm can effectively solve the problem of deterministic friction state in the process of mechanical calculation of the tubing string, which has important guiding significance and engineering value for the mechanical calculation and operation safety analysis of coiled tubing operation.

Background: Glaucoma and diabetic retinopathy are the leading causes of blindness due to an irreversible damage to the retina which results in vision loss. Early detection of these diseases through regular screening is especially important to prevent progression. The image of retinal fundus is the main evaluating strategy for the glaucoma and diabetic retinopathy detection. Then, automated eye disease detection is an important application of retinal image analysis. Compared with classical diagnostic techniques, image classification by convolutional neural networks (CNN) have the potential for better cost-effective performance.

Methods: In this paper, we propose the use of MATLAB – retrained AlexNet CNN for computerized eye diseases identification, particularly glaucoma and diabetic retinopathy, by employing retinal fundus images. The acquisition of the database was carried out through free access databases and access upon request. A transfer learning technique is used for retraining the AlexNet CNN. Specifically, the model divides the fundus image dataset into training and testing data.

Results: As datasets were added by network training, different values were reported for validation accuracy, false positives and false negatives, precision, and recall. Thus, having NetTransfer I with a validation accuracy value of 94.3% for two classes. NetTransfer II with a validation accuracy value of 91.8% for two classes. NetTransfer III with a validation accuracy value of 89.7% for three classes. Net transfer IV with a validation accuracy value of 93.1% for three classes. Finally, NetTransfer V with a validation accuracy value of 92.1% for three classes.

Conclusions: Re-training of the AlexNet network proved to be a powerful tool to create disease detection systems having high accuracy values and being able to discern between more than two diseases.
Grammatical transformations in translation of political speeches
Authors: Ababilova Nataliia , Maiboroda Rymma
Published: January 2023

The paper is devoted to the problem of translation of political speeches, which is extremely relevant today, as political activity plays a special role in society, affects the country’s place in the international arena and its relations with other coun-tries. Politicians have the opportunity to appeal to both the international community and their compatriots, gain recognition, demonstrate their leadership and represent their country in the best possible way via speeches. Translation of political speeches is considered to be one of the most complicated types of translation, which is the area of increased linguistic responsibility. Translation transformations, which are defined as certain structural or semantic changes that are the result of lexical and grammatical differences in languages, are used to achieve translation equivalence (translation adequacy) despite the differences in the formal and semantic systems of two languages. The research is aimed at examining the peculiarities of political speeches and difficulties arising in the process of their rendering into Ukrainian. This paper consists of six main sections. The first is an introduction to the study. The second examines the definition and features of political speeches given by national and foreign scientists. The third section explains the methodology used in the study and the data selection process. In the course of analysis, the existing scientific literature concerning the topic at hand providing valid grounds for the practical part of the work has been analyzed and grammatical translation transformation examples have been selected and examined. The research data was taken from the website of the US Embassy in Ukraine. Thereafter the focus shifts to challenges the students face in translation of political speeches and highlights the grammatical transformations classification that constituted the theoretical basis of the research. The fifth section is devoted to analyzing the data and the last section summarizes the findings of the study.
Cognitive and semiotic determinants of sign order in gestural and pictorial event representations
Authors: Vastenius Anu , Zlatev Jordan , Van de Weijer Joost
Published: January 2023

The way people order signs in non-verbal event representations of events has been a topic of extensive research in recent decades, with conflicting findings. Based on a literature review, we distinguish the following factors that have been argued to influence sign order: (a) diagrammatic iconicity, (b) manipulation vs. construction events, (c) reversibility, (d) most common word order of L1, (e) the semiotic system (gesture, depiction) used, and (f) a putative “natural” Agent–Patient–Act order. To test the role of these factors, we conducted a study where Swedish participants observed events that varied with respect to reversibility and construction/manipulation status, and then had to communicate them to an addressee using gestures for half the stimuli. For the other half, they used sequences of simple drawings of the event participants and the action. The results showed the huge influence of the semiotic system (e) on sign order. There was a role of reversibility (c) only when gestures were used, while L1 word order (d) only had an effect when sequences of pictures were used. The “ontological status” of the Patient (b) was shown to affect the representations in both semiotic systems but was much stronger for gestures. Even the two most general factors (a) and (f) where shown to be sensitive to the type of semiotic system. Future studies of how such cognitive and semiotic determinants interact are needed to fully understand the phenomenon of sign order preference.
Repensar la formación carcelaria en Colombia desde una perspectiva filosófica.
Authors: Sarmiento Aponte Ingrid Victoria
Published: January 2023

En Colombia el hacinamiento se ha constituido históricamente como uno de los principales problemas de los centros carcelarios y penitenciarios, hecho que durante la crisis sanitaria desencadenada por el COVID-19 se hizo más evidente; así como la manera en que este atenta contra los Derechos Humanos fundamentales de los individuos privados de la libertad. Por otra parte, y desde una perspectiva educativa, otro de los problemas que enfrenta el sistema penitenciario del país, es la reducida oferta de proyectos formativos que repercutan en el desarrollo de la dimensión moral de las personas condición de cárcel, falencia que, sumada a muchas otras, dificulta la resocialización y explican la alta reincidencia en los delitos. En el presente artículo, apoyados en una lectura de algunas de las obras de Dewey dedicadas a pensar la naturaleza humana, su carácter moral y las características de una auténtica educación moral, se aboga por una formación ética para personas en condición de cárcel donde confluyan el interés por transformar las condiciones en las que se desenvuelven y la creación de escenarios que favorezcan el desarrollo de su capacidad para examinar reflexivamente la experiencia a través de la filosofía. Ahora bien, las conceptualizaciones que aquí se presentan fueron precursoras de un proceso investigativo que inició en la Universidad Nacional Abierta y a Distancia en el año 2021 bajo la orientación y acompañamiento del doctor José Barrientos-Rastrojo, profesor titular de la Universidad de Sevilla y director del proyecto Internacional Boecio, y en el marco del cual se desarrollan talleres de estoicismo en cárceles orientados por estudiantes de distintos programas de la Escuela de Educación y la Escuela de Ciencias Sociales, Artes y Humanidades. Este proyecto investigativo condujo a la adaptación de los talleres a las modalidades virtual y a distancia para el trabajo con distintos grupos vulnerables y su impacto se encuentra actualmente siendo evaluado por distintos trabajos de grado asociados a esta investigación.

La narrative Syad como un método de Filosofía Aplicada para minimizar los sesgos cognitivos.
Authors: Devarakonda Saathvikd
Published: January 2023

El término “salud” no solo se aplica a las esferas física, social y psicológica, sino que también a la esfera filosófica. La oorientación filosófica ha surgido recientemente como un método útil para afrontar problemas personales relacionados con la salud filosófica mediante el empleo del diálogo socrático y técnicas relacionadas para examinar los pensamientos, valores, intenciones y acciones relevantes y para estimular las acciones que alivian los problemas. En este artículo, presento dos doctrinas filosóficas jainistas antiguas interdependientes que aplicables a la práctica de la orientación filosófica, a saber, la Anekāntavāda, de naturaleza ontológica, y la Syadvada, de naturaleza epistemológica. Anekāntavāda es la doctrina de la no unilateralidad, es decir, plantea que la realidad es multifacética, y Syadvada es la doctrina que establece que el conocimiento es relativo y en perspectiva. El artículo explica algunas formas en las que estas doctrinas alinadas pueden aplicarse fructíferamente para resolver varios problemas relacionados con los tipos de sesgos cognitivos y la racionalidad limitada, que a menudo se presentan en las sesiones de orientación filosófica. La investigación ha demostrado que la limitada racionalidad y la heurística son las principales causas de los sesgos cognitivos. Este documento analiza las causas y los impactos de los sesgos cognitivos en los procesos de formación de juicios y toma de decisiones y se centra principalmente en dos aplicaciones de las dos doctrinas jainistas: (1) comprender las múltiples dimensiones de la realidad a través de Anekāntavāda para minimizar la dependencia de la heurística y de una racionalidad limitada, y (2) identificar y minimizar sesgos cognitivos específicos. El objetivo es proponer la Anekāntavāda y la Syadvada como herramientas metodológicas de orientación filosófica para ser utilizadas y proponer la combinación de Syadvada y Terapia Narrativa – el método “Syad-Narrative” – para atenuar los sesgos cognitivos y así producir resultados en la orientación filosófica

Authors: Virde Harshal , Dohare Devendra
Published: January 2023

The water-carried sewerage system has replaced the older, more basic technique of excreta disposal as the cities have grown. The infrastructure of any society's water supply and sewage system is crucial. The purpose of a sewer network is to move home or industrial waste water from a source location to a treatment facility or disposal site. The sewage system consists of a network of sewer lines that, at their nodal points, collect and discharge waste materials into a separate network of sewer lines. Since then, a lot of researchers have made contributions to this topic. As a result, an effort has been undertaken in this paper to gather data from research papers on the design of sewerage network systems. The objective of this paper is to proposed a treatment unit and design of sewerage network for Saatvik Vihar Phase-II, Indore (Madhya Pradesh), with the help of SewerGEMS software also using the process of Moving Bed Biofilm Reactor (MBBR) for the cleaning of wastewater of the society.

Human activity has drastically impacted the earth's ecology, resulting in significant changes in the environment over the ages. Developing countries like India have extensive intervention of life form activities has intensified environmental problems, soil degradation, greenhouse effect, global warming, and ecological imbalance. These difficulties have directly impacted the quality and maintenance of the environment. Research and statistics clearly indicate that if current trends continue, situations would worsen in the near future. Sustainable solutions, such as bioremediation for water pollution and microbial decomposition for crop residue waste, are becoming increasingly important and demand huge exposure in order to minimize the negative effects of human activities and assure sustainable development. Microorganisms play a significant part in carbon as well as other nutrient cycling, and their influence on climate change deserves special consideration. If microorganisms and nutrient cycling are connected, they operate as an effective strategy for addressing many environmental issues like soil degradation, global warming, and ecological imbalance. Thus, this paper aimed to close a research and evaluation gap by analyzing environmental challenges and their long-term growth.
Influence of Organic Waste on Nutrient Composition of Compost and the Impact of Sawdust on Composting Process.
Authors: Parihar Parveen , Choudhary Rakesh
Published: January 2023

To improve soil health and fertility use of compost is a better idea than chemical fertilizers. Compost is a product of the degradation of waste organic matter. The choice of organic waste to get a good quality of compost is needed for the proper recycling of organic waste. So, the present study was to identify the effect of the type of organic waste on the physical properties and nutrient content of compost. The experiment was conducted with four types of organic waste (Fruit waste, vegetable waste, cooked leftovers, and farm waste). The analysis shows that type of organic waste in composting influences the nutrient content of compost but the physical properties of compost are not much affected by the type of organic waste. It was observed that waste from cooked leftover food contains more nutrient content than other waste. So this waste is more suitable for composting. During the study effect of sawdust as a bulking agent was also observed. Sawdust significantly affects the composting process as it accelerates composting and also affects the quality of compost.
Dog: A Companion on the Journey to Independence Beyond Attachment Trauma
Authors: Yoo Misung
Published: January 2023

The ‘Animal symbol’ symbolizes the primitive and instinctive nature of human beings, and has been psychologically important since ancient times. Among many animals, dogs, in particular, were originally wolves, but were the first to be domesticated by humans. It is an animal that people attach to and regard as a family member because it is absolutely obedient to and dependent on humans when they perceive humans as the leader. However, in most countries, the dog is an animal that has been recognized not only as a loyal, home-keeper, but also as a guide between the dead and the underworld and as a human companion. The reason is that although dogs have been domesticated and become new animals, they still have the instinctive characteristics of wolves. Infants in the early stages of their lives also have a time when they rely entirely on their mothers, similar to the characteristics of domesticated dogs. However, when a healthy attachment is formed, the baby is psychologically separated from the mother and self-development begins toward independence. However, if psychological independence is not achieved for some reason, similar to a domesticated dog, they become completely dependent on their mother and are swallowed up by their maternal mother, and they may become stuck in childhood dependence, causing difficulties in interpersonal relationships. In this case, our reason, guided by the instinctive energy of our inner dog, begins a healing journey towards independence. In this paper, among the many symbols of dogs, the dog as a symbol of loyalty, the dog as a healing animal, the dog as a guide to the unconscious, and the dog as a symbol of instinct and intuition were examined. In addition, the symbolic meaning of the dog discussed above was confirmed through the case where a high school client who was psychologically dependent on his mother while having sandplay therapy started a healing journey by using a dog symbolically to achieve attachment and independence.
The Life Experiences of Wives Suffering from Marital Conflicts: A Narrative Inquiry using Sandtray Images
Authors: Kwak Sookyung , Seo Mia
Published: January 2023

This study used narrative inquiry to understand the experiences of three wives who were suffering from marital conflicts. We collected data in the form of stories of life experiences of the participants and the images which they expressed in their sandtrays. Data collection involved interviews with each of the three participants over four 60-minute sessions. Narrative analysis of the data revealed the following meanings of marital conflict: ‘scabs picked over and over’ as the appearance of marital conflict; ‘glacial-interglacial cycles’ as the cycle of marital conflict; ‘seesaw not showing where it is tilted’ as the degree of marital conflict; and ‘walking up the spiral stairs slowly but constantly, at least until today’ as the trajectory of marital conflict. Based on the results of this study, it is proposed to develop an efficient counseling intervention strategy for wives suffering from marital conflict.
Genoese-Italian “vulgar” phraseology in GEPHRAS and GEPHRAS2
Authors: Autelli Erica
Published: January 2023

Vulgar terms have often been avoided in language and dialect dictionaries, although one can already find many of them in historical dictionaries and they have a century-long lexicographic tradition. There is a desideratum for further studies from a contrastive perspective as only certain languages or varieties have been analysed in more detail. This paper will focus on Genoese-Italian phraseology and in particular on GEPHRAS and GEPHRAS2, which represent two new phraseographical projects that will result in one unique phraseological dictionary, which will also collect such vulgar expressions. In particular, the phrasemes based on the headwords BELLIN, BAGASCIA, CÛ, MOSSA (usually ‘cock’, ‘whore’, ‘ass’ and ‘pussy’ or ‘bollocks’) will be compared.
Die Rolle der Schulsprachenpolitik bei der Normalisierung der llengua pròpia in Katalonien und der Region Valencia seit Beginn der Transición
Authors: Kühne Ina
Published: January 2023

Catalonia and the Valencian Country are characterized by a very special sociolinguistic situation, which consists in the coexistence of the Castilian language as the official language of the Spanish state and the regional languages as co-official languages in the respective Autonomous communities. This constellation holds the potential for political tension, since in the past ‒ but still today ‒ it lead/leads to linguistic conflicts, whose origins lie in the political history of Spain, during which the regional languages time and time again were subject to repressions and prohibitions, that came to a head during the dictatorship of Francisco Franco. Since the beginning of the Spanish transition to democracy it was possible to work towards a resolution of the linguistic conflicts by means of legal norms and a corresponding language legislation. Especially the language teaching policy is an important area of language policy, since it has a long-lasting influence on the language skills of the citizens. The present article gives a detailed description of the measures taken in Catalonia and the Valencian Country concerning the language teaching policies since the beginning of the Spanish transition to democracy. Furthermore, it analyzes, in what way the language skills of the citizens of the Autonomous communities of Catalonia and Valencia have been improved through the applied language teaching policies and finally offers a comparison between the two Regions in this respect. The analysis is based on statistical surveys realized by the Institut d’Estadística de Catalunya (IDESCAT) and the Generalitat Valenciana.
The magic of moulding – Applying upper limb cast in a child
Authors: Doshi Chintan
Published: January 2023

Upper limb fractures are common in pediatric population. Most of these injuries need application of cast as a routine procedure. The purpose of this review is to discuss the art of applying a well moulded upper limb cast in children in order to get excellent outcome. Material to be selected for cast application depends on the fracture configuration, requirement for moulding, and other physical properties of the cast required for particular patient. A well –moulded cast should be applied in order to prevent further fracture displacement. It is important to understand and maintain certain radiographic indices in order to ensure a good outcome from casting technique. Preventing cast related complications like wet cast, skin complication, compartment syndrome, thermal injuries, and cast syndrome are important consideration when taking care of the cast. Patient education is one of the most important factor in ensuring proper cast maintenance.
‘Severs Disease’ – Manifestations & Management
Authors: Gupta Khyati , Shah Avi
Published: January 2023

Calcaneal apophysitis (Sever’s Disease) is a common cause of heel pain in growing children. It’s true incidence and etiology in unknown but, recent evidence supports overuse injury as an underlying etiology. It can present as either unilateral or bilateral heel pain in active growing children or adolescents who had a history of new-onset sports activity. Diagnosis mainly relies on a thorough clinical examination with a positive squeeze test being confirmatory. Radiologic imaging may be unnecessary but can help rule out or avoid missing other problematic conditions. Treatment options are mainly conservative and include rest, medications, therapy, or orthosis. Educating parents and coaches is pivotal for the prevention of these self-limiting conditions in young athletes. Evidence suggests a return to sports in most in a few weeks to months after appropriate care.

Authors: Bhide Prajakta , Vaidya Sandeep
Published: January 2023

Intoed and out-toed gait in children can occur due to foot deformities or torsional alignment of the femur and/or tibia. In most cases, these deformities are physiological and resolve with age. Physical examination consists of assessment of rotational profile of the lower limb which includes foot progression angle, torsional alignment of the femur and tibia, and foot shape. Few cases may be due to underlying pathological conditions which need to be identified and treated.

Published: January 2023

Background: Coronavirus disease 2019 (COVID-19) has spread throughout the world, affecting people from all walks of life, including orthopedic doctors in India. We’ve We’ have seen a significant decrease in the number of patients. The study’s study’s goal was to determine the extent to which the epidemic has affected Indian orthopaedic practice. Methods: An online survey of currently practicing Indian orthopaedic doctors was done. The study enlisted the help of 500 orthopaedic surgeons. A statistical analysis was performed to determine the relationship between the demographic profile of study participants and other orthopaedic practice characteristics. Results: Maximum participants belonged to the age group of 30-–40 years (39.8%) and only 13.6% belonged to the age group of 51-–60 years. Approximately, 85.8% participants were married. Out of all, 86% participants were consultants and 14% were residents. Most of the participants (35.2%) have 5-–10 years of practice experience. Most of the participants were working in charity hospitals (31.4%) and very few of them (4.8%) were working in government hospitals. Conclusion: Practicing orthopaedic surgeons working in the private sector and running their own (individual) hospitals and clinics have been the most badly afflicted in terms of earnings, while those working in the government sector and medical universities have been the least afflicted.

Authors: Khemkar Sachin , Pawar Eknath , Shet Vipul , Kambli Mrinal , Modi Nihar , Mokashi Mitali
Published: January 2023

Background: Osteochondroma is the most common benign skeletal neoplasm and is found most often in long bones, especially in the distal femur and proximal tibia. They usually present as painless swelling near the joint and can be complicated by mechanical irritation, compression or injury of adjacent structures, fracture, malignant transformation, and post-operative recurrence. Locking of the knee refers to flexion of the knee without complete extension and passive extension is limited resulting in significant pain. Excision is a successful form of the treatment for symptomatic osteochondromas. Case Report: A case of osteochondroma of the proximal tibia illustrates extra-articular cause of locked knee secondary to the incarceration of pes anserinus tendons by the lesion. Conclusion: Surgical excision of the bilobed pedunculated posteromedial proximal tibia osteochondroma and restoration of the gracilis and semitendinosis to its normal anatomic position resulted in the complete resolution of symptoms.

Authors: Rajani Amyn M , Rajani Kareena , Mittal Anmol RS , Shah Urvil A , Rajani Khushi A , Rajani Kashish A
Published: January 2023

Introduction: Enchondroma is a common bone tumor; however, its location in the proximal epi-metaphyseal region of the tibia is a rare finding. Its management is complicated by the weight-bearing nature of the site and despite an array of available treatment modalities in the literature, there is no fixed consensus. Case Report: Through this case, we report a 60-year-old female who was evaluated for bilateral knee osteoarthritis. On plain radiography, a lytic lesion was noted which on CT guided biopsy was confirmed to be an enchondroma of the right proximal tibia. The patient underwent extensive curettage, allograft impaction, and supplementary fixation by a poly ethyl ether ketone plate. Following a period of immobilization, she was able to walk full weight-bearing after 3 weeks of the surgery and carry out her daily activities at 2 months. At 1 year postoperatively, the patient achieved excellent clinical, radiological, and functional outcomes without any complications. Conclusion: Management of an enchondroma in weight-bearing regions of long bones can pose multiple challenges. Timely diagnosis and management by thorough curettage, uncompromised allograft impaction, and supplementary fixation by a PEEK plate give excellent short-term and long-term results.
Iatrogenic CSF Leak from CT Myelogram Leading to Cauda Equina Compression: A Case Report
Authors: Megalla Martinus , Decilveo Alexander P , McCunney Robert M , Ruoff Mark
Published: January 2023

Introduction: Although magnetic resonance imaging (MRI) is the preferred imaging modality for diagnosing cauda equina syndrome (CES), computerized tomography (CT) myelogram may be used in patients who are unable to undergo MRI. When inserting the needle for CT myelogram, there is a risk of cerebrospinal fluid (CSF) leak, which theoretically could lead to CES. To the best of our knowledge, there are no reports of CT myelogram resulting in cauda equina compression. Case Report: We report the case of a 38-year-old man who underwent surgical decompression for CES and developed an iatrogenic CSF leak from a pre-operative CT myelogram causing recurrent thecal sac compression requiring repeat surgery and dural repair. Conclusion: Although CT myelogram may be used to aid in the diagnosis of CES, consideration should be given to the potential risk for causing a CSF leak and resultant thecal sac compression.
Total hip arthroplasty after seven decades of a Girdlestone situation due to tuberculous coxitis in childhood
Authors: Pelczar Michal P , Nowakowski Andrej M
Published: January 2023

Introduction: Tuberculous coxitis accounts for about 15% of all osteoarticular tuberculosis cases and is the second most common after spinal tuberculosis. In extensive cases, Girdlestone resection arthroplasty is an option for primary surgical treatment followed in the course of time, with total hip arthroplasty (THR) to increase function. However, the remaining bone stock is generally poor. In these cases, the Wagner cone stem offers good pre-conditions for bone restoration even seven decades after Girdlestone, as presented here. Case Report: A 76-year-old male patient was admitted to our department with a painful hip, who had previously been treated with Girdlestone at the age of 5 years after being diagnosed with tuberculous coxitis. After an intensive and very detailed evaluation of treatment options, the decision fell on rearticulating with a THR, even though primary surgery lay seven decades back. Since it was not possible to insert an appropriate non-cemented pressfit-cup, an acetabular reinforcement ring and a PE low profile cup were inserted, cemented with less inclination to avoid or reduce hip instability. A fissure around the implant (Wagner cone stem) was secured with numerous cerclages. Surgery was performed by the senior author (A.M.N.) postoperatively, the patient suffered a prolonged delirium. Ten months after surgery, the patient was satisfied with the result and reported a meaningful improvement in his daily quality of life. His mobility increased significantly and represented by his ability to climb stairs without being in pain or needing walking aids. Today, 2 ½ years after THR surgery, the patient still reports being satisfied and pain free. Conclusion: Despite transient complications postoperatively, we are happy to report a very satisfactory clinical and radiologic outcome after 10 months. The today 79-year-old patient reports having a higher quality of life since rearticulation of his Girdlestone situation. However, the long-term effects and survival rate of this procedure need to be observed furthermore.

Authors: Ambulgekar Rajesh K , Ghag Niranjan Sunil
Published: January 2023

Introduction: Although osteoid osteomas are relatively common lesion, sites such as distal phalanx are still rarely observed. These lesions present with characteristic nocturnal pain due to prostaglandins and may also be associated with clubbing. Diagnosis of these lesions at uncommon sites becomes tricky and 85% are misdiagnosed. Case Report: A 18-year-old patient presented with the left distal phalanx of little finger clubbing and nocturnal pain (visual analogue scale [VAS] score: 8). After clinical workup and investigation to rule out infective and other causes, the patient was posted for excision of the lesion with curettage. Post-surgery outcome showed reduced pain (2 months post-operative VAS score: 1) and good clinical results. Conclusion: Although osteoid osteoma of distal phalanx is a rare entity and difficult to diagnosed. Complete excision of lesion shows promising results both in terms of reduction of pain and functionally.
Trans-Scaphoid Perilunate Fracture Dislocation Managed With Open Reduction: A Case Report
Authors: Ambulgekar Rajesh K , Masne Pratik Sharad , Jadhav Akshay
Published: January 2023

Introduction: Perilunate dislocations (PLD) and perilunate fracture dislocations (PLFDs) are complex wrist injuries, resulting from high energy trauma such as motor vehicle accidents, fall from height, and extreme athletic injuries. About a fourth (25%) of PLD are missed at the initial presentation. Urgent closed reduction should be attempted in the emergency room itself to minimize the morbidity due the condition. However, if it is unstable or irreducible the patient the can be posted for open reduction. Perilunate injuries can result in poor functional results, if left untreated patients may have long-term morbidity due to complications such as avascular necrosis of lunate and scaphoid, post-traumatic arthritis, chronic carpal tunnel syndrome, and sympathetic dystrophy. Patient outcome even after treatment is also controversial. Case Report: We have brought one such case where the patient, a 29-year-old male suffered a Transscaphoid PLFD, presented to us late and was treated with open reduction with good functional outcome postoperatively. Conclusion: Early and prompt diagnosis followed by early intervention is necessary to prevent the potential risk of avascular necrosis of lunate and scaphoid and secondary osteoarthritis in PLFDs to reduce the long-term morbidity and long-term follow-up is advisable to diagnose and treat the long-term sequelae.

Published: January 2023

A microwave driven five-level X-type atomic system is proposed to diffract weak probe light into higher-order directions via the phenomenon of electromagnetically induced grating. In the proposed scheme, the effect of various system and field parameters on its higher-order diffraction efficiency is studied. The present atomic scheme offers excellent control over higher-order diffraction intensities by utilizing the microwave induced quantum interference effect. It is observed that the desired first-order diffraction efficiency can be attained through optimal selection of microwave field strength and relative phase factor.

Authors: Xu Ying , Zhang Weiye , Tian Chuanshan
Published: January 2023

Measuring magnetic response from spin and current is of fundamental interest in condensed matter physics. Negatively charged nitrogen-vacancy (NV−) centers in diamond are emerging as a robust and versatile quantum sensor owing to their high sensitivity, nanometer-scale spatial resolution, and noninvasive operation with access to static and dynamic magnetic and electron transport properties. In this review, we discuss the rapidly growing interest in the implementation of NV− magnetometry to explore condensed matter physics, focusing on three topics: anti/ferromagnetic materials, superconductors, and metals/semimetals/semiconductors.

Published: January 2023

Data from national health information systems are essential for routinely tracking progress, programmatic decision-making and to improve quality of services. Understanding the data elements captured in patient registers which are building blocks of national HMIS indicators, enables us to standardize data collection and measurement of key indicators for tracking progress towards achieving maternal and newborn health goals. This analysis was done through a review of antenatal care (ANC), childbirth and postnatal care (PNC) registers from 21 countries across five geographic regions. Between July and October 2020, country-based maternal and newborn experts, implementing agencies, program managers, and ministry of health personnel were asked to share the registers in use. Both paper-based and electronic registers were obtained. Twenty ANC registers, eighteen childbirth and thirteen PNC were available and analyzed. Both longitudinal and cross-sectional ANC and PNC registers were obtained, while the childbirth registers included in the analysis were all cross-sectional. Fifty-five percent (11/20) ANC registers and 54% (7/13) PNC registers were longitudinal. In four countries, the registers were electronic, while the rest were paper-based (17 countries). Sub-analysis of registers from four countries (Ghana, Kenya, Nigeria, and Zambia) where the 2017/2018 and 2019/2020 registers were available showed that the latest versions included 21/27 (78%) of data elements that are critical in the computation of key maternal and newborn care indicators. This analysis highlights some areas in where there are data gaps in data on pregnancy and childbirth. Program managers and health workers should use data gathered routinely to monitor the performance of their national health system and to guide the continuous improvement of health care services for women and newborns. The findings can help to inform the standardization of pregnancy and childbirth registers, and provide information for other countries seeking to introduce indicators in their health systems.
Food insecurity in the Eastern Indo-Gangetic plain: Taking a closer look

Objective

Food security is an important policy issue in India. As India recently ranked 107th out of 121 countries in the 2022 Global Hunger Index, there is an urgent need to dissect, and gain insights into, such a major decline at the national level. However, the existing surveys, due to small sample sizes, cannot be used directly to produce reliable estimates at local administrative levels such as districts.

Design

The latest round of available data from the Household Consumer Expenditure Survey (HCES 2011–12) done by the National Sample Survey Office of India used stratified multi-stage random sampling with districts as strata, villages as first stage and households as second stage units.

Setting

Our Small Area Estimation approach estimated food insecurity prevalence, gap, and severity of each rural district of the Eastern Indo-Gangetic Plain (EIGP) region by modeling the HCES data, guided by local covariates from the 2011 Indian Population Census.

Participants

In HCES, 5915 (34429), 3310 (17534) and 3566 (15223) households (persons) were surveyed from the 71, 38 and 18 districts of the EIGP states of Uttar Pradesh, Bihar and West Bengal respectively.

Results

We estimated the district-specific food insecurity indicators, and mapped their local disparities over the EIGP region. By comparing food insecurity with indicators of climate vulnerability, poverty and crop diversity, we shortlisted the vulnerable districts in EIGP.

Conclusions

Our district-level estimates and maps can be effective for informed policy-making to build local resiliency and address systemic vulnerabilities where they matter most in the post-pandemic era.

Advances

Our study computed, for the Indian states in the EIGP region, the first area-level small area estimates of food insecurity as well as poverty over the past decade, and generated a ranked list of districts upon combining these data with measures of crop diversity and climatic vulnerability.
Mapeamento de trabalhos sobre temas socioambientais
Authors: Medeiros da Fonseca Eril , Duso Leandro
Published: January 2023

Este trabalho tem por objetivo investigar como ocorre a abordagem de questões/temas socioambientais em práticas educativas no ensino de Ciências. A partir de uma abordagem qualitativa, realizou-se um levantamento nas atas do Encontro Nacional de Pesquisa em Educação em Ciências (ENPEC) e em periódicos da área de Educação Ambiental no período de 2010 a 2020. Realizou-se o processo analítico através da análise de conteúdo. Os resultados foram sistematizados em duas categorias: visão reducionista sobre temas socioambientais e abordagem de aspectos da realidade e problemática local. Alguns trabalhos abordam questões ambientes de forma dissociada entre sociedade e natureza ou antropocêntrica.
Recifes de coral

Published: January 2023

Os recifes de corais são ecossistemas importantes com grande biodiversidade. No entanto, este ecossistema vem sofrendo ameaças constantes. Neste contexto, a prática da educação ambiental na escola, aliada às novas ferramentas didáticas digitais, torna-se fundamental para sensibilizar e conscientizar sobre a fragilidade do ecossistema recifal. Esse trabalho tem por objetivo analisar como os jogos didáticos e ferramentas tecnológicas auxiliam na aprendizagem e na prática de educação ambiental na escola. Após revisar a bibliografia sobre a questão analisada, foi-se proposto um jogo educacional digital que auxilia na aprendizagem, permitindo a compreensão da dinâmica das relações ecológicas no ecossistema recifal, assim como sensibiliza em relação à importância de sua preservação.
pressupostos históricos da Educação Ambiental e a crise ambiental atual
Authors: Macedo Pereira Alexandre , De Assis Estevam Lucena Figueiredo Iohanna Maria , Da Silva Andrei Rufino
Published: January 2023

A partir de 2017, diversos países elegeram governos ultraconservadores que ignoram a crise ambiental. Este artigo tem como objetivo central reconstituir a história da Educação Ambiental em âmbito nacional e internacional. Como objetivos específicos, o artigo pretende a) recuperar a memória histórica da luta pela implementação e consolidação da Educação Ambiental (EA) no combate à crise ambiental e b) apresentar as ações do governo federal brasileiro e de seus aliados no parlamento que visam a desmontar as políticas públicas ambientais, em particular a Política Nacional de Educação Ambiental (PNEA). Metodologicamente, esta é uma pesquisa bibliográfica. Concluímos que, no Brasil, está em curso um projeto de governo cujo objetivo é aniquilar as políticas ambientais.
Trilhas interpretativas ecológicas e a conservação da biodiversidade na Educação Ambiental
Authors: De Vechi Anderson , De Oliveira Magalhães Júnior Carlos Alberto , Barion Romagnolo Mariza
Published: January 2023

O presente artigo teve por objetivo realizar uma pesquisa investigativa acerca dos artigos publicados nos últimos dez anos (2009-2019) sobre a temática das trilhas interpretativas ecológicas envolvendo conservação e preservação da biodiversidade local. E através da Educação Ambiental que se utilizaram dos instrumentos das trilhas interpretativas ecológicas para aprimorar a sensibilização coletiva referente à importância da preservação das áreas naturais. Realizou-se uma revisão bibliográfica sistematizada por meio das plataformas do Google Acadêmico, Periódicos da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (Capes), Plataforma ResearchGate e Scientific Electronic Library Online (Scielo) e Scopus. A análise se deu a partir de 41 artigos selecionados, que buscavam apresentar a abordagem presente na Educação Ambiental nos últimos dez anos. A metodologia empregada foi a investigativa bibliográfica quantitativa, abarcando o resultado dos principais métodos de abordagem na preservação da biodiversidade e dos biomas brasileiros. A partir dos resultados pode-se concluir que a inter-relação com a biodiversidade, ecologia e educação ambiental, encontrados nos artigos estudados, demonstraram que a utilização de práticas relacionadas com a educação ambiental, por meio de trilhas interpretativas ecológicas ocorreram, predominantemente, na biodiversidade da Mata Atlântica. Conclui-se que o contato direto com as áreas naturais foi o método presente na maioria dos artigos pesquisados, apresentando resultados satisfatórios, não limitando, assim, a Educação Ambiental ao um simples método teórico.
pesquisa fenomenológica no contexto climático
Authors: Marcomin Fátima Elizabeti , Becker Lidiane Gil , Nardi Tatiani do Carmo
Published: January 2023

O texto apresenta algumas reflexões sobre as potencialidades de atividades pedagógicas, sobre o clima, junto a estudantes do ensino fundamental de uma escola da rede pública no sul de Santa Catarina – Brasil, durante a pandemia da Covid-19 em 2021. A Cartografia do Imaginário, em seus elementos Bachelardianos, sustentou a pesquisa Fenomenológica. Aprofundamentos atinentes aos conceitos, às causas e consequências dos problemas regionais e globais referentes à questão climática, agravada pela ação humana, estiveram presentes nas atividades e discussões promovidas na escola. As manifestações a partir da arte, expressas em desenhos e poemas, retrataram eventos climáticos relevantes e a pandemia; contudo ainda carecem de aprofundamentos de conhecimentos e sinalizam a necessidade de processos formativos, contínuos, críticos e participativos na interface escola-comunidade acerca do tema.
