Published: April 2023

Electromagnetic field (EMF) and geomagnetic field (GMF) are inescapable environmental factors experienced by all living organisms including plants. Despite the progresses made in the field of plant-senses, the impact of Electromagnetic field (EMF) and geomagnetic field (GMF) on plant growth and development is not fully explored. In this context influence of exposure intensity and duration of exposure to low frequency (50 Hertz) electromagnetic field produced by a locally designed monoaxial Helmholtz Coil on germination parameters of Triticum aestivum L. (Wheat) has been studied in the present work. Wheat seeds were exposed to magnetic field strengths of 30, 60 and 75 Gauss for different periods of time (10, 20 and 30 minutes) inside the Helmholtz Coil. Control plants were grown under the local geomagnetic field (50 micro Tesla). Germination parameters like mean germination time, germination percentage, co- efficient of germination etc. were calculated for each test condition. Results indicated that among all the test conditions the alternating magnetic field with exposure rate of 60 Gauss/30 minutes found most conducive to Wheat germination which is reported here for the first time. These results are encouraging to work further on the effect of magnetic field on biochemical and molecular changes that may be resulting these observed phenomena.

Published: April 2023

Nearly every facet of modern life has been profoundly impacted by the development of nanotechnology. Researchers from a variety of disciplinary domains are becoming interested in nanoparticles (NPs) with distinctive physicochemical features and broad medicinal uses. Because of their distinct structural characteristics, NPs have a wide range of uses in medication delivery, chemical and biological sensing, and other related fields. Oxidative processes are unavoidable as they are important in energy metabolism and the utilization of nutrients. The treatment available may not be sufficient to treat the disease as it is caused by many factors and there are so many adverse effects caused by the synthetic medicine available. The present study evaluated the phytochemical, phenolic, flavonoid, and antioxidant activity of Noni seed synthesized with silver nitrate. Fresh seeds of Morinda citrofolia obtained were extracted by maceration method and synthesis was done by reacting 10 mL of the Morinda citrofolia seed extract with 90 mL AgNO3 solution. Phytochemical, TPC, TFC, and antioxidant tests were carried out according to standard procedure. Results revealed that Noni seed AgNps contains alkaloids, tannins, flavonoids, resins, and terpenoids. Phenolic content was non-significantly different (p>0.05) and flavonoid content was significantly different (p<0.05) in comparison to gallic acid. Noni seed-AgNps extract also showed high antioxidant activity because of their higher percentage inhibitions very near to the controls used. From the study, we can conclude that Noni seed-AgNps extract has many important secondary metabolites and it has a potential for strong antioxidants.

Contact dermatitis is a frequent reason for consultation in dermatology. In recurrent and erythrodermic forms, patch testing in search of an allergenic substance is necessary. The aim of this study is to describe the preliminary results of patch testing using the standard European battery at the Dermatology Hospital of Bamako. This was a descriptive cross-sectional study conducted at the Dermatology Hospital of Bamako over a period of two years. All patients screened for recurrent or extensive eczema were included. The patch tests performed were those of the standard European battery. After application of the allergens, the tests were read at 48 and 72 hours. During the study 5777 cases of eczema were detected , 29 patients presenting a recurrent and/or extensive form were tested, of which 28 patients had a positive test at 72 hours (96%): 17/29 males (56%) and 12/25 females, i.e. a sex ratio of 1.42. The mean age of the patients was 39 years (range 7-72 years). With the exception of 1 patient, all patients were poly-sensitized: 9 patients reacted to 2 allergens, 9 others to three allergens and 6 to at least 5 allergens. Potassium dichromate was found 12 times, paraphenylene diamine 7 times, nickel 5 times and finally epoxy resin and fragrance mix 3 times each. In Africa, in the absence of suitable test batteries, the standard European battery was used. The positivity rates observed in our series are higher than those reported in other African populations. Although the detection of an allergen alone is not sufficient to explain a clinical picture, it is possible that the poly-sensitization observed in our cases could be one of the consequences of exposure to several allergens. In addition, it would have been interesting to explore the role of phytotherapy in the clinical pictures observed in our cases.

Published: April 2023

The objective of this work is to highlight and discuss a rare cause of curable spinal cord compression with a favourable evolution, through the case of a posterior thoracic epidural arachnoid cyst for which we will discuss its clinical, paraclinical, therapeutic and evolutionary characteristics, with review of the literature. The patient was a six and a half year old boy with no previous pathological history. He was admitted for progressive gait problems with myalgia. MRI showed an extradural cystic lesion in the thoracic spinal cord opposite D5-D10 with a signal similar to that of the CSF. A laminectomy followed by evacuation of the cyst with partial removal of the wall was performed. Pathological examination confirmed the diagnosis. The evolution was marked by a total disappearance of the initial clinical symptomatology in the patient. Although rare, the extradural arachnoid cyst is a potential cause of reversible spinal cord compression for which surgical resection is the treatment of choice.

Introduction: Neonatal and child morbidity is a threat to socio-economic and health progress in sub-Saharan Africa. In paediatric in-patient practice, knowledge of morbidity is important for health care personnel to ensure optimal patient management. The frequency of these pathologies varies between countries. Objective: The objective of our study was to identify the main morbidities in children hospitalised in the paediatric ward of the commune II health centre. Methods: This was a retrospective descriptive study from 1 January to 31 December 2017. We included all children aged 01 month to 15 years hospitalized in the pediatric ward. The study included 418 children aged 0 to 15 years hospitalised in the department during the study period. Results: Children aged 0 to 5 years were the most represented 89.4% with a majority in the 0 to 1 month age group (39%). Males were the most represented with 58%, i.e. a M/F sex ratio of 1.4. ). The children's mothers were not in school in 78% of cases and were housewives in 70%, and 95% of the parents were married. Socioeconomic status was very low in 34% of families. The patients consulted after 1 to 2 days in 47.1% of cases. Admission to the service was direct in 84% and hospitalisation was more frequent between July and November in 66.3%. The reasons for hospitalization of children were dominated by fever 39% followed by respiratory difficulties 29% and convulsions 10%. Malaria was the first cause of hospitalization with 30%.

Authors: Zaghba Nahid , Assia Boussehra , Benjelloun Hanane , Chaanoun Khadija , Yassine Najiba
Published: April 2023

Introduction: Pleural aspergillosis is a rare pathology; it is defined by an infection of the pleural cavity by an opportunistic fungus of the genus Aspergillus. Observation: We report the case of a 24-year-old female patient treated for pulmonary tuberculosis complicated by a left pyopneumothorax drained for 5 months. The reason for consultation 3 months after stopping the antibacillary treatment was a purulent bronchial syndrome, left chest pain with a tingling sensation and exertional dyspnea. Clinical examination revealed an aerated effusion syndrome in the left hemithorax. Chest imaging showed a left pneumothorax with thickening of the visceral pleura and a left upper lobar alveolar focus with clearing within it. Aspergillus serology was positive. The patient had undergone video-assisted thoracoscopy, which revealed the presence of false membranes and whitish deposits of mycotic appearance. The biopsy of the pseudomembranes was in favor of pleural aspergillosis. The patient was put under antifungal treatment for 6 months with a good clinical and radiological evolution. Conclusion: Aspergillus is a mycelial fungus formed by filaments that penetrate the airways by inhalation of its spores. Pleural localizations are rare. Sequelae of tuberculosis, broncho pleural fistulas, pleural drainage and pulmonary resection are considered the main conditions predisposing to infection of the pleural space by aspergillus. The diagnosis is confirmed by pleural fluid culture or pleural biopsy.

Authors: Lee Yoon Jin , Lee Changjin , Oh Soojeong , Chun Duk-Hee
Published: April 2023

Providing adequate sedation while ensuring normoventilation is a challenge during an awake craniotomy. The use of sedative agents may cause hypoventilation and apnea, inducing hypoxemia and hypercapnia. High-flow humidified nasal oxygen delivery devices have shown positive results in various clinical areas. Here, we present two case reports of patients undergoing awake craniotomy who experienced a sudden decrease in oxygen saturation while receiving dexmedetomidine sedation. Despite being aroused to take deep breaths, the patients’ oxygen saturation did not return to baseline. Arterial blood gas analysis (ABGA) revealed a significant fall in partial pressure of oxygen. To address the hypoxemia, we initiated high-flow nasal oxygen (Optiflow) 10 L/min instead of conventional oxygen treatment via nasal prong. Follow-up ABGA results showed that Optiflow 10 L/min effectively provided adequate oxygenation and prevented the retention of carbon dioxide. Optiflow 10 L/min was successful in managing the patients’ hypoxemia while maintaining adequate oxygenation, ventilation, and sedation during awake craniotomy.

Published: April 2023

Extramammary Paget's disease (EMP) is a rare form of intraepithelial adenocarcinoma that primarily affects older women. This case report describes a 40-year-old patient diagnosed with EMP who presented with a rapidly growing, painful, and bleeding perianal erosion that did not respond to antifungal treatment. The patient underwent wide excision of the lesion and the postoperative course was uneventful. The case highlights the importance of considering EMP in the differential diagnosis of perianal eruptions, particularly in older women, and emphasizes the need for careful histological examination and appropriate management.

Метод створення лісових культур дуба звичайного (Quercus robur L.), вид садивного матеріалу та його якість істотно впливають на стан, продуктивність і стійкість майбутніх насаджень. Нині як серед українських, так і зарубіжних дослідників немає єдиної думки щодо методів створення штучних дубових насаджень і більш придатного виду садивного матеріалу у різних лісорослинних умовах. Дослідження проведено у південно-східній частині Лівобережного Лісостепу (ДП "Харківська ЛНДС", Липецьке лісництво) в умовах свіжої кленово-липової діброви. Дослідні культури було створено в 2010 р. різними методами та видами садивного матеріалу – садінням сіянців із закритою і відкритою кореневими системами та висіванням жолудів. Категорія лісокультурної площі – свіжий зруб, утворений після здійснення лісовідновної рубки смугово-поступовим способом (ширина смуги вирубування – 25 м) в ослаблому стиглому порослевому дубовому деревостані. Дослідні лісові культури було створено чистими за складом, простими за формою та наступними за часом. Установлено, що вищі таксаційні показники (середня висота і діаметр) характерні для дубових молодняків, створених сіянцями із закритою кореневою системою, порівняно з молодняками, створеними сіянцями з відкритою кореневою системою та висіванням жолудів. Проте ця різниця виявилася неістотною – тільки на 3 і 2 % за висотою та 2 і 7 % за діаметром. З'ясовано також, що дуб у складі досліджуваних молодняків, створених висіванням жолудів, відзначається вищою інтенсивністю росту за висотою, розрахованою за середнім поточним приростом, відповідно на 2 і 6 %, порівняно з молодняками, створеними садінням сіянців із закритою та відкритою кореневими системами та санітарним станом. В умовах свіжої діброви південно-східної частини Лівобережного Лісостепу України під час штучного лісовідновлення дубових насаджень, за наявності достатньої кількості жолудів (у насіннєві роки) та за відсутності загрози їх пошкодження гризунами або кабанами потрібно віддавати перевагу висіванню жолудів. Цей метод є порівняно недорогим і таким, що найбільше відповідає природі лісу. За відсутності достатньої кількості жолудів доцільно здійснювати штучне лісовідновлення методом садіння сіянців як з відкритою, так і закритою кореневими системами.

Published: April 2023

Запропоновано концептуальний підхід до управління будівельними ризиками в діджиталізованому середовищі з використанням онтологічної структуризації для нагромадження знань щодо ризиків, факторів та шляхів їх актуалізації. Актуальність теми зумовлена недостатністю використання інформаційних технологій для управління будівельними ризиками в Україні. Проаналізовано наукові дослідження з обраної проблематики, використано методи групування та структурування інформації, оцінено технологічні можливості інформаційного моделювання будівель (BIM) та семантичної web-технології для створення онтологічної методології для управління знаннями про ризики будівництва. З'ясовано, що управління безпекою в будівництві є трудомістким процесом, який потребує значних затрат часу і великих обсягів знань інженерів-проєктувальників. Проаналізовано наявні інструменти цифровізації управління ризиками. Рекомендовано зосереджувати в діджиталізованому середовищі семантично організовані, онтологічно анотовані та динамічно пов'язані з конкретними будівельними проєктами знання про ризики для забезпечення візуальної підтримки інформаційної карти, аналізу і повторного використання збережених знань. Запропоновано створювати карти ризиків з фіксацією їх потенційної взаємозалежності у вигляді семантичної мережі структурованих знань. Показано, що в межах представленої концепції забезпечується ідентифікація будівельних процесів і потенційних ризиків з одночасним аналізом факторів і шляхів, що сприяє адекватному вибору запобіжних заходів. Окреслено переваги застосування BIM у підтриманні планування безпеки та інтеграції автоматизованої ідентифікації ризиків на спеціалізованих цифрових платформах. Зазначено про обмеження представленого концептуального рішення, окреслено шляхи їх вирішення. В майбутньому доцільно розширити дослідження, включивши, окрім суто будівельних, інші типи ризиків, зокрема логістичні та інфраструктурні.

The molluscs of the Duddingston Loch area, Edinburgh, Scotland: comparison of the present with the 19th and 20th centuries
Authors: Sumner A.T.
Published: April 2023

The molluscan fauna of Duddingston Loch, Edinburgh, Scotland and surrounding areas has been studied in recent years, and compared with earlier reports, particularly that of D.K. Kevan in 1929–1930. Ten freshwater mollusc species that were recorded in the past have not been found in recent years, while other species have arrived and flourished. Reasons for such changes may include adverse effects of algal blooms and the introduction of certain fish. The terrestrial mollusc fauna in the Duddingston Loch area has not changed in the same way, but several alien species that have become widespread in the Edinburgh area and in Scotland generally have also appeared here. As a result, a total of 76 species of mollusc has been recorded in the Duddingston Loch area, making this one of the richest sites for molluscs in Scotland.

The Blodwen Lloyd Binns Bequest: three decades of major positive impacts on Glasgow Natural History Society
Authors: Downie J.R. , Weddle R.B. , Futter S. , Mable B.K.
Published: April 2023

The establishment of the Blodwen Lloyd Binns (BLB) Bequest in 1991 and the transformative impact of its first 20 years on the development of Glasgow Natural History Society have previously been reported. This paper describes the following decade, up to 2022. BLB’s requests, including publication of a biography of John Scouler and floras of Renfrewshire and Lanarkshire have been carried out. Sadly, Peter Macpherson, author of the Lanarkshire flora, died before publication of his book. The overall capital value of the Bequest has been maintained, and supplemented in the last decade by additional legacies and donations. The income generated has been used to fund a wide variety of natural history projects: publication of The Glasgow Naturalist and several books, a BLB prize and lecture series, the organisation of several conferences, bursaries to help young scientists learn identification and recording skills, and funding of a wealth of public engagement and research work, including student expeditions and tools to help communities appreciate local biodiversity. Although the COVID-19 pandemic curtailed some work normally funded by the Bequest, the lack of funding applications allowed strengthening of the Bequest’s capital through re-investment.

Authors: Shih Neng-Hui , Tsai W. C. , Wang Chih-Hsiung
Published: April 2023

This study proposes a heuristic inspection policy to address the existence of type I and II inspection errors. The deterioration process often shifts from an in-control state to an out-of-control state toward the end of a production lot, producing more nonconforming products. As a result, if the initial (late-produced) products in a production lot are chosen for inspection, the products identified as nonconforming (conforming) may need to be inspected repeatedly. The decision regarding the demarcation point between initial and late-produced products, their respective inspection rounds, and the production lot size must be made simultaneously to minimize the expected total cost per conforming product. This paper provides numerical examples to explore the effect of inspection errors on the optimal production lot size, inspection policy, and the associated cost.
The Metaphysics of Time and Temporal Experience in Africa: A Cultural and Philosophical Perspective
Authors: Muhamba Denis , Sanga Innocent , Ndemo George
Published: April 2023

This paper explores the metaphysics of time and its relevance to Africa from a cultural and philosophical perspective. The paper argues that the Western concept of time, which is based on linear and objective concepts, is not the only way to explain time and temporal experience to all cultures and civilizations. By examining traditional African perspectives on time, the paper demonstrates the importance of considering cultural and philosophical differences in the study of time and temporal experience. The paper concludes that the Western concept of time must be supplemented with an understanding of the diverse and complex ways in which time is experienced and understood in Africa

Authors: Hosny Mostafa A. , Ibrahim Sameh A.
Published: April 2023

This work presents a fast transient boost converter in 40nm CMOS technology. The converter is fully integrated and utilizes MOS+ MOM capacitors to minimize the area. The unique pseudo-6-bit Analog to digital converter helps the system achieve its fast trainset load changes. The design also utilizes 32-phases of operation to achieve small ripples though it uses a relatively small output capacitor. The converter generates a 3 V supply from a 1.8 V input and achieves a fast transient response of 1mA to 24mA, and vice versa, in 100 ps with an undershoot and overshoot not exceeding 4% of the regulator’s output and ripples less than 40mV peak-to-peak.

This article illustrates and explains Charles Dicken’s novel, Great Expectations, based on reader- narration, themes, techniques, figures of speech, language, and characters. The article applies reader-response theory response theory. It delves into the novel’s core to discover its aesthetic elements, decorations, style of in the novel’s analysis since this theory sheds light on the interaction and involvement of readers with the text and its elements. Readerresponse theory enables readers to be part of the narration and the literary work. As a result, this paper clarifies the impact of readers on literary texts; it shows how readers deal with the text during their journey of analysis. This paper demonstrates the influence of Great Expectations as a literary masterpiece of Charles Dickens on the readers who read and analyze its meanings and lessons. The article also clearly looks for an identity for the reader and gives him a real chance to explore the text with more than one concept. This paper includes a lot of information about the Victorian age images and acts and their influence on the characters and readers. The article begins with an introduction regarding the novel and its author. Also, it refers to the reader-response theory, its definition, its qualities, and its influence on the reader. The body paragraphs are great pieces where the novel explores its themes, language, stylistic devices, and techniques.

The conclusion is more precise; an overview of the things must be seen as good points to realize while studying with a grand finale when the writer summarizes the novel with its aim and function.
GTC/CanariCam Mid-infrared Polarimetry of Magnetic Fields in Star-forming Region W51 IRS2

Published: April 2023

We present 0.″4 resolution imaging polarimetry at 8.7, 10.3, and 12.5 μm, obtained with CanariCam at the Gran Telescopio Canarias, of the central 0.11 pc × 0.28 pc (4.″2 × 10.″8) region of W51 IRS2. The polarization, as high as ∼14%, arises from silicate particles aligned by the interstellar magnetic field (B-field). We separate, or unfold, the polarization of each sightline into emission and absorption components, from which we infer the morphologies of the corresponding projected B-fields that thread the emitting- and foreground-absorbing regions. We conclude that the projected B-field in the foreground material is part of the larger-scale ambient field. The morphology of the projected B-field in the mid-infrared (mid-IR) emitting region spanning the cometary H ii region W51 IRS2W is similar to that in the absorbing region. Elsewhere, the two B-fields differ significantly with no clear relationship between them. The B-field across the W51 IRS2W cometary core appears to be an integral part of a champagne outflow of gas originating in the core and dominating the energetics there. The bipolar outflow, W51north jet, that appears to originate at or near SMA1/N1 coincides almost exactly with a clearly demarcated north–south swath of lower polarization. While speculative, comparison of mid-IR and submillimeter polarimetry on two different scales may support a picture in which SMA1/N1 plays a major role in the B-field structure across W51 IRS2.
Constraints on the Binarity of the WN3/O3 Class of Wolf–Rayet Stars*
Authors: Massey Philip , Neugent Kathryn F. , Morrell Nidia I.
Published: April 2023

The WN3/O3 Wolf–Rayet (WR) stars were discovered as part of our survey for WRs in the Magellanic Clouds. The WN3/O3s show the emission lines of a high-excitation WN star and the absorption lines of a hot O-type star, but our prior work has shown that the absorption spectrum is intrinsic to the WR star. Their place in the evolution of massive stars remains unclear. Here we investigate the possibility that they are the products of binary evolution. Although these are not WN3+O3 V binaries, they could still harbor unseen companions. To address this possibility, we have conducted a multiyear radial velocity study of six of the nine known WN3/O3s. Our study finds no evidence of statistically significant radial velocity variations, and allows us to set stringent upper limits on the mass of any hypothetical companion star: for probable orbital inclinations, any companion with a period less than 100 days must have a mass <2M
⊙. For periods less than 10 days, any companion would have to have a mass <1M
⊙. We argue that scenarios where any such companion is a compact object are unlikely. The absorption lines indicate a normal projected rotational velocity, making it unlikely that these stars evolved with the aid of a companion star that has since merged. The modest rotation also suggests that these stars are not the result of homogenous evolution. Thus it is likely that these stars are a normal but short-lived stage in the evolution of massive stars.
Food safety in health: a model of extraction for food contaminants
Authors: Cai Yuanyuan , Liang Hao , Zhang Qingchuan , Xiong Haitao , Tong Fei
Published: April 2023

Contaminants are the critical targets of food safety supervision and risk assessment. In existing research, food safety knowledge graphs are used to improve the efficiency of supervision since they supply the relationship between contaminants and foods. Entity relationship extraction is one of the crucial technologies of knowledge graph construction. However, this technology still faces the issue of single entity overlap. This means that a head entity in a text description may have multiple corresponding tail entities with different relationships. To address this issue, this work proposes a pipeline model with neural networks for multiple relations enhanced entity pairs extraction. The proposed model can predict the correct entity pairs in terms of specific relations by introducing the semantic interaction between relation identification and entity extraction. We conducted various experiments on our own dataset FC and on the open public available data set DuIE2.0. The results of experiments show our model reaches the state-of-the-art, and the case study indicates our model can correctly extract entity-relationship triplets to release the problem of single entity overlap.

Published: April 2023

This work is an approach that brings together Learning Analytics and Ontologies for a data classification that promotes improvements and behavioral changes for students and teachers on e-Learning platforms. Combining training courses, dashboards, user's evaluations, and based on Design Science Research (DSR) methodology, artifacts were created. One of the most important artifacts of our work is the Sapes tool that aims to improve students’ perceptions of their learning path and to promote a better teacher overview to follow their students' progress. The results showed high approval by the participating students and teachers, who perceived the Sapes tool as a good facilitator of the teaching-learning process, with possibilities for self-monitoring, dynamization of the learning sequence and better interactivity with colleagues, highlighted as absent in standard e-Learning courses. In addition, the application changed the behavior of users towards the content provided by the teacher, with students performing self-management and self-regulation that were not commonly performed previously.
