Myasthenia gravis in a pediatric patient with Lennox-Gastaut syndrome following responsive neurostimulation device implantation: illustrative case
Authors: Zuckerman David A , Beaudreault Cameron P , Muh Carrie R , McGoldrick Patricia E , Wolf Steven M
Published: November 2023

BACKGROUND

Myasthenia gravis (MG) is an autoimmune disorder in which the postsynaptic acetylcholine receptor of the neuromuscular junction is destroyed by autoantibodies. The authors report a case of MG in a pediatric patient who also suffered from Lennox-Gastaut syndrome (LGS) and is one of a limited number of pediatric patients who have undergone placement of a responsive neurostimulation (RNS) device (NeuroPace).

OBSERVATIONS

A 17-year-old female underwent placement of an RNS device for drug-resistant epilepsy in the setting of LGS. Five months after device placement, the patient began experiencing intermittent slurred speech, fatigue, and muscle weakness. Initially, the symptoms were attributed to increased seizure activity and/or medication side effects. However, despite changing medications and RNS settings, no improvements occurred. Her antiacetylcholine receptor antibodies measured 62.50 nmol/L, consistent with a diagnosis of MG. The patient was then prescribed pyridostigmine and underwent a thymectomy, which alleviated most of her symptoms.

LESSONS

The authors share the cautionary tale of a case of MG in a pediatric patient who was treated with RNS for intractable epilepsy associated with LGS. Although slurred speech, fatigue, muscle weakness, and other symptoms might stem from increased seizure activity and/or medication side effects, they could also be due to MG development.
Intraoperative intraarterial indocyanine green video-angiography for disconnection of a perimedullary arteriovenous fistula: illustrative case
Authors: Jung Youngkyung , Lindgren Antti , Ahmed Syed Uzair , Radovanovic Ivan , Krings Timo , Andrade-Barazarte Hugo
Published: November 2023

BACKGROUND

Intraarterial (IA) indocyanine green (ICG) angiography is an intraoperative imaging technique offering special and temporal characterization of vascular lesions with very fast dye clearance. The authors’ aim is to demonstrate the use of IA ICG angiography to aid in the surgical treatment of a perimedullary thoracic arteriovenous fistula (AVF) in a hybrid operating room (OR).

OBSERVATIONS

A 31-year-old woman with a known history of spinal AVF presented with 6 weeks of lower-extremity weakness, gait imbalance, and bowel/bladder dysfunction. Magnetic resonance imaging revealed an extensive series of flow voids across the thoracic spine, most notably at T11–12. After partial embolization, she was taken for surgical disconnection in a hybrid OR. Intraoperative spinal digital subtraction angiography was performed to identify feeding vessels. When the target arteries were catheterized, 0.05 mg of ICG in 2 mL of saline was injected, and the ICG flow in each artery was recorded using the microscope. With an improved surgical understanding of the contributing feeding arteries, the authors achieved complete in situ disconnection of the AVF.

LESSONS

IA ICG angiography can be used in hybrid OR settings to illustrate the vascular anatomy of multifeeder perimedullary AVFs and confirm its postoperative disconnection with a fast dye clearance.
BARGAINING POWER, ECONOMIC INDEPENDENCE, DECISION MAKING: CASE STUDY OF WOMEN INFORMAL WORKERS THROUGH PHILOSOPHER JOHN STUART MILL
Authors: Munte Alfonso , Monica Monica
Published: November 2023

The scope of this research is at the level of experience of women informal workers in Pasar Besar Palangka Raya. This experience speaks of bargaining power, empowerment in terms of decision-making, economic independence, body and future authorsity and freedom of expression. Nevertheless, the authors found the imprisonment of double burden in the lives of 3 research subjects. The purpose of this study is to show the extent to which the narrative leads them to live the values of equality through informal work. The research method used is qualitative research with interviews., then the authors recorded, transcribed, made a factual solid and then classified into themes that are close to this research. The results of the research through the experiences of women informal workers in Pasar Besar show that women are found to be empowered over assets, time and in decision-making. On the other hand, both empowerment and imprisonment of women's double burden make John Stuart Mill's philosophical lens dialogue in it when talking about marriage as friendship and not as property or slavery. Mill's intersubjective space becomes a buffer in the narrative of women's experiences of informal workers. In addition, the authors finds that gossiping as a negative stigma by society becomes erroneous when confronted with the daily life practices of women informal workers. Gossip/ngerumpi is able to make women's space a place of self-development, self-protection and self-promotion when women are hit by a flood of fatigue, boredom in terms of waiting for the arrival of buyers.

Authors: Agustinus Agustinus , Mettang Marta
Published: November 2023

This study delves into the intriguing world of "To Pembuni," a revered and enigmatic figure in the beliefs of the Nosu people. "To Pembuni" is known for its hidden nature and mystical traits. Using a nuanced approach through phenomenological research, the goal is to deeply understand the rich experiences and beliefs of the vibrant Nosu community about "To Pembuni." The findings reveal a dual existence of "To Pembuni" in both the real world of Nosu and a unique ethereal realm. This enigmatic presence is believed to occasionally take human form or inhabit dwellings. Its origin stems from regular community members seeking solace from heavy taxation by retreating into the forest. A key highlight is the deep respect and warm connection the Nosu people share with "To Pembuni," showcasing their profound rapport. An interesting theme is the intricate relationship between safeguarding the environment and the mystical bond between the Nosu and "To Pembuni," highlighting the interconnectivity of all life. Additionally, the study introduces the depths of mystical theology through the lens of William Johnston, an erudite Irish Jesuit scholar. Johnston's perspective portrays mystical theology as a discipline revealing esoteric wisdom gained through divine communion, with love as the guiding force. In conclusion, this research offers insights into mystical experiences and their impact on beliefs, underscoring the need for environmental preservation. It invites further exploration of mysticism as a path to harmoniously connect with the divine, championing love and compassion for all creation, echoing William Johnston's mystical theology.

Authors: Al-Hamzawi Ali A.
Published: November 2023

Background: Substance use disorders (SUDs) are among the common psychiatric disorders and constitute a major public health concern. Iraqi’s were exposed to widespread violence and wars in the last decades. High prevalence of alcohol and substance use was reported recently in Baghdad. Research literature documented the association of SUDs with exposure to trauma events e.g. wars, terrorist attacks and natural disaster. Published articles on SUDs among prisoners in Iraq are scarce. Therefore, this work was carried out to report on SUDs among prisoners in Al-Diwania governorate and its relation to antisocial activity.Methods: A total of 1200 prisoners in Al-Diwania civilian prison were included in the study during the period from 2nd January to 2nd May 2010. A questionnaire using ICD 10 characteristics of SUDs was used. The requested data in addition to characteristics of SUDs were demographic data and type of crime. In order to study the association of SUDs with criminal act, a control group (150 prisoners out of 1050) was selected randomly from the prisoners without SUDs.Results: The study revealed a rate of (12.5%) of SUDs The peak age of abuse was at age 31 – 35 years. More than half of the sample which was composed of male prisoners was in age 25 to 35 years. Fifty three (35.3%) of the abusers were illiterate, and 70 (46.7%) finished the primary school. Only 2 of the abusers (1.3%) had higher education. Thirty (20%) of the abusers were unemployed, 100 (66.67%) were self-employed and only 18 (12%) were employed.

Heavy Metal Contamination of Medicinal Plants in India – A Perspective
Authors: Rani Suman , Sisodia Rama
Published: November 2023

The presence of heavy metals in medicinal plants (MP) is a matter of serious concern as it directly affects human health. In India, the problem is especially significant since the country is a major consumer as well as exporter of medicinal plant-based raw materials and products. Raw material available in the market is often reported to contain traces of heavy metals and these consequently compromise the quality of medicinal plants-based medicinal formulations. In the present study, the reports of heavy metals in MP from India were collated to ascertain the extent of the problem and highlight the source of contamination. The states with the highest number of metals above permissible limits included Chhattisgarh, Maharashtra, Delhi, Kerala, Karnataka, and Uttar Pradesh. The levels of Cd and Cr metals were found to be the highest in Rajasthan, Odisha, Pb in Kerala and Hg, As in the state of Tamil Nadu. Plants growing in areas having mining activities as well as those growing on urban landscapes such as along roadsides or areas having an inflow of industrial effluents or agricultural run-off showed higher metal content than the standard limit. The presence of metals in natural habitats such as the mangroves and low lands of the Himalayan range was also noted. The review provides an insight into the magnitude of the issue, its causes and the possible lacuna that needs to be addressed to mitigate the problem.

Published: November 2023

In this study, we present our findings from examining a gas lift tower for produced and tap water de-oxygenation, applying the nitrogen purging at an ultra-fine bubble scale (18 μm average size). The experiments were conducted for produced water samples grafted with polyacrylamide concentration 300 ppm with a measured bulk viscosity of 5 mPa.s. Upon applying a series of experimental sets, 0 ppm DO was attained in all examined operational schemes (semi batch and once through) within various time limits, depending on the water level in the column. Considering the zero DO level as an objective function, the results showed an improvement of 5.7–14 folds in reaching the 0 ppm DO upon experimenting with the ultra-fine bubble purging in different schemes, compared with of the results obtained from the ordinary bubble size (mm scale). The results show that DO reached < 10 ppb within 23 minutes with nitrogen flowrate 3 L/min while DO reaching < 10 ppb within 28 minutes with nitrogen flowrate 5 L/min. Furthermore, implementing the ultra-fine bubble nitrogen purging was successful in running the de-oxygenation tower in a full continuous mode at a balanced inlet/outlet water flow rate. This has been done after reaching stability in the column operation (lasting around 1 hour for 422 L of examined water sample). The stable fine bubbles cloud in the column was quite efficient in treating water influent stream to be exited directly at 0 ppm DO within the same effluent flow rate. The treatment efficiency has shown an increase with increasing water level in the column, resulting in a denser layer/cloud of fine bubbles. This result suggests a unique approach/solution for the complete removal of DO from produced water, which is accounted effective to be adopted industrially

Authors: Maktof Zainab R. , Radia Nadher D.
Published: November 2023

This study investigated the ability of nanocomposite hydrogels (NaCMC-g-AAc/COOH-MWCNTs) to adsorb Pb(II) ions, an environmental pollutant. The characterisation of the hydrogel and nanocomposite was achieved using FTIR, FESEM, XRD and TGA techniques, XRD techniques. Adsorption studies showed that equilibrium was reached after 120 minutes with a removal efficiency of 82%. Many factors were also studied, as the results indicated that the adsorption equality was of the (S4) type according to Giles’ classification, and the adsorption parallels for Pb (II) ions matched the Freundlich adsorption model. The absorption process was found to be endothermic, with absorption increasing with increasing temperature. Positive content and entropy are noted, as well as negative free energy, indicating the physical and spontaneous nature of the process.

Authors: Miao Shidi , Jia Haobo , Huang Wenjuan , Cheng Ke , Zhou Wenjin , Wang Ruitao
Published: November 2023

OBJECTIVES:

This study explores a deep learning (DL) approach to predicting bone metastases in breast cancer (BC) patients using clinical information, such as the fat index, and features like Computed Tomography (CT) images.

METHODS:

CT imaging data and clinical information were collected from 431 BC patients who underwent radical surgical resection at Harbin Medical University Cancer Hospital. The area of muscle and adipose tissue was obtained from CT images at the level of the eleventh thoracic vertebra. The corresponding histograms of oriented gradients (HOG) and local binary pattern (LBP) features were extracted from the CT images, and the network features were derived from the LBP and HOG features as well as the CT images through deep learning (DL). The combination of network features with clinical information was utilized to predict bone metastases in BC patients using the Gradient Boosting Decision Tree (GBDT) algorithm. Regularized Cox regression models were employed to identify independent prognostic factors for bone metastasis.

RESULTS:

The combination of clinical information and network features extracted from LBP features, HOG features, and CT images using a convolutional neural network (CNN) yielded the best performance, achieving an AUC of 0.922 (95% confidence interval [CI]: 0.843–0.964, [Formula: see text] 0.01). Regularized Cox regression results indicated that the subcutaneous fat index was an independent prognostic factor for bone metastasis in breast cancer (BC).

CONCLUSION:

Subcutaneous fat index could predict bone metastasis in BC patients. Deep learning multimodal algorithm demonstrates superior performance in assessing bone metastases in BC patients.
Managing public sector data: National challenges in the context of the European Union’s new data governance models
Authors: Buttow Clarissa Valli , Weerts Sophie
Published: November 2023

In its regulatory enterprise to improve the conditions of data sharing and reuse, the European Union has enacted new legislation: the Data Governance Act (DGA). The DGA envisages new forms of sharing public sector data (PSD). Based on a legal analysis of the DGA and an in-depth study of data governance literature, this paper highlights what is at stake in the new regulatory framework and argues that more than the mere openness of more PSD will be necessary to ensure that the European Union policy goals are achieved, especially those concerning enhancing innovation for the common good. From this perspective, the paper argues that the public data trust model of data governance and the Responsible Research and Innovation approach offer two powerful tools for public sector data governance. In this context, this paper contributes to the debate about new data governance models and discusses tools and frameworks enabling the use of data for the common good. It also provides insights to public administration practitioners aiming to implement a framework for increased and sustainable PSD sharing.

Authors: Sandhu Muhammad Abdullah , Amin Asjad , Tariq Sana , Mehmood Shafaq
Published: November 2023

Dengue mosquitoes are the only reason for dengue fever. To effectively combat this disease, it is important to eliminate dengue mosquitoes and their larvae. However, there are currently very few computer-aided models available in scientific literature to prevent the spread of dengue fever. Detecting the larvae stage of the dengue mosquito is particularly important in controlling its population. To address this issue, we propose an automated method that utilizes deep learning for semantic segmentation to detect and track dengue larvae. Our approach incorporates a contrast enhancement approach into the semantic neural network to make the detection more accurate. As there was no dengue larvae dataset available, we develop our own dataset having 50 short videos with different backgrounds and textures. The results show that the proposed model achieves up to 79% F-measure score. In comparison, the DeepLabV3, Resnet achieves up to 77%, and Segnet achieves up to 76% F-measure score on the tested frames. The results show that the proposed model performs well for small object detection and segmentation. The average F-measure score of all the frames also indicates that the proposed model achieves a 76.72% F-measure score while DeepLabV3 achieves a 75.37%, Resnet 75.41%, and Segnet 74.87% F-measure score.

Published: November 2023

BACKGROUND: Tongue diagnosis is a crucial traditional Chinese medicine (TCM) inspection method for TCM syndrome differentiation and treatment. OBJECTIVE: The primary research focus was on tongue image characteristic parameters of patients with non-small cell lung cancer (NSCLC). Analysis of the tongue image parameters of various pathological stages of NSCLC provides technical support for establishing an integrated Chinese and Western auxiliary diagnosis and efficacy evaluation medicine system for lung cancer that integrates tongue image features. METHODS: Tongue image characteristics of 309 patients with NSCLC and 206 controls were collected and analyzed clinically. The T-test or rank sum test and logistic regression analysis were applied to analyze the characteristics of tongue image indicators of different pathological stages of NSCLC. RESULTS: There were differences in tongue image characteristics in the NSCLC group compared to the control group. The tongue quality and brightness of the tongue coating in the NSCLC group increased, the red component was reduced, the tongue coating thickened, and the yellow component increased compared to the healthy control group. A comparison of tongue image indexes of NSCLC in different pathological stages showed that stage IV had lower TB-b and higher TB-a than stage I. In addition, stage IV had lower TB-b than stage II + III, showing an increase in the blue and red components of the tongue in stage IV and the appearance of cyanotic tongue features. CONCLUSION: The tongue image characteristics of NSCLC patients differed from those of the control group. Tongue imaging indicators can reflect the characteristics of tongue images of patients with NSCLC. The tongue image characteristics of patients with stage IV lung cancer are bluish and purple compared with those with stage I, II, and III. It is suggested that the tongue’s image characteristics can be used as a reference for the pathological classification of NSCLC and judgment of the disease process.

Authors: Kumbi Arun , Birje Mahantesh N.
Published: November 2023

Now a days, the Internet of Things (IoT) plays a vital role in every industry including agriculture due to its widespread and easy integrations. The agricultural methods are incorporated with IoT technologies for significant growth in agricultural fields. IoT is utilized to support farmers in using their resources effectively and support decision-making systems with better field monitoring techniques. The data collected from IoT-based agricultural systems are highly vulnerable to attack, hence to address this issue it is necessary to employ an authentication scheme. In this paper, Auth Key_Deep Convolutional Neural Network (Auth Key_DCNN) is designed to promote secure data sharing in IoT-enabled agriculture systems. The different entities, namely sensors, Private Key Generator (PKG), controller, and data user are initially considered and the parameters are randomly initialized. The entities are registered and by using DCNN a secret key is generated in PKG. The encryption of transmitted data is performed in the data protection phase during the protection of data between the controller and the user. Additionally, the performance of the designed model is estimated, where the experimental results revealed that the Auth Key_DCNN model recorded superior performance with a minimal computational cost of 142.56, a memory usage of 49.5 MB, and a computational time of 1.34 sec.
On the forecast of the martensitic transformation deve-lopment during winding pipes made of austenitic steel on a reel
Authors: Shimov G. V. , Bushueva N. I. , Loginov Yu. N.
Published: November 2023

A pipes winding process numerical simulation is performed in the coil drawing technology implementing at different reel diameters. The features of the stress-strain state in the process of the pipe winding process are investigated to predict the products properties. The pipe winding process modeling is performed using the finite element method in the DEFORM-3D. The strain distribution color levels for the considered variants are given. The difference in the deformed state is shown. A graph of the deformation value dependence on the reel size and a graph of the martensite depending on the reel diameter are presented. The deformation zone numerical simulation during austenitic steel pipes coil drawing showed a difference in the stress-strain state depending on the reel diameter choice. The calculations also made it possible to predict the martensitic transformation development probability in steel 12X18010T in order to as-sess impact on the finished products properties. It is established that with a decrease in the reel radius, there is an in-crease in tensile deformations (in the wall outer layers) and compression (in the wall inner layers) and an martensitic transformation development intensification. The strain degree distributions gradients (along the pipe section) and the characteristic points at which the martensitic transformation occurs most intensively during the winding and pipe bend-ing are established. The results obtained can be applied both to predict the pipe winding implementation, as the coil drawing testamentary stage and to assess the cold deformation effect on the products properties during the heat ex-change equipment installation
Flowsheets for hydroxyacetone–phenol binary mixture separation: The use of special distillation methods
Authors: Gaganov I. S. , Rytova E. V. , Frolkova A. K.
Published: November 2023

Objectives. To study the possibility of hydroxyacetone–phenol binary mixture (a constituent of a mixture of phenol production by the cumene method) separation in flowsheets based on the use of distillation special methods. This is the addition of separating agents to increase the relative volatility of the components of the original mixture, and the variation of pressure in the columns.

Methods. A computational simulation in Aspen Plus® was used as the research method. Mathematical modeling of the vapor–liquid equilibrium was carried out using a local compositions model Non-Random Two Liquid. The viability of the latter was confirmed by comparing experimental and calculated on phase equilibrium data, and azeotropic data. The average relative error does not exceed 3%.

Results. The dependence of the composition and boiling point of the hydroxyacetone–phenol azeotrope on pressure was determined in a computational experiment (as the pressure increases, the azeotrope is enriched with phenol). The possibility of using a complex of columns operating under different pressures to separate the mixture was shown (the shift of the azeotrope is about 9%). The change in the relative volatility of components of the original mixture in the presence of a high(diethylene glycol) and a low-boiling (acetone) separating agent was investigated. Both solvents are selective agents used in extractive and re-extractive distillation processes. Three technological separation flowsheets containing two distillation columns were proposed.

Conclusions. The study established the operation parameters of the columns (number of theoretical stages, feed stages of the original mixture and separating agent, and reflux ratio) and energy consumption (total heat supplied to the columns boiler) of three separation flowsheets ensuring the production of products of a given quality (not less than 0.99 mol fractions). The flowsheet with diethylene glycol is characterized by the lowest energy consumption. It is recommended that complexes of extractive and re-extractive distillation be further optimized. This enables the second product of cumulus production—acetone—to be involved in the technological cycle.

This study was conducted to determine the effectiveness of story theatre in improving speaking skills in English to Grade 12 General Academic Strand (GAS) students, University of Cebu- Main Campus, S.Y. 2020-2021. The result was used as a basis for a proposed action plan. Specifically, the study sought answers to the pretest scores of the control and experimental groups, the posttest scores of the control and experimental groups, the significant difference between their pretest scores, the significant difference between their pretest-posttest scores, and the significant difference between their posttest scores. A quasi-experimental design was used for the control and experimental groups. There were 40 Grade 12 students as subjects of the study. The experimental group was treated with the use of story theatre, while the control group was taught using the lecture method. Pretest and posttest evaluations were used to measure the academic performance of the students for both groups. The findings of the study revealed that most of the students had good level performances. The posttest scores of both groups marked an increase, and the posttest mean value of the experimental group was significantly higher than that of the control group. Student’s speaking skills in the English language are effectively enhanced with the use of story theatre. The interest, retention and learning ability of the students are better realized when they are actively involved with a combination of the written word, acting, movement and characterization.

Одним із ефективних підходів до оцінки нелінійної структури, поведінки, моделювання, прогнозування розвитку фітоценозів на основі сучасних математичних підходів і методів є лінеаризація, коли складні нелінійні відношення спрощуються до лінійних форм певного типу. У методичному відношенні лінійність можна трактувати як проекцію нелінійної структури із багатомірного простору на площини, на яких лінії мають певну форму, довжину та спрямованість, тобто векторизованість. При цьому виникають проблеми щодо адекватності відображення результатів і не спотворення суті, що вимагає перевірки результатів різним способом розрахунків та різної репрезентативності даних, а також пошуку лімітуючих меж. У роботі наводяться приклади лінеаризації з різних областей фітоценології. Оцінка репрезентативності вибірки геоботанічних описів союзів для фітоіндикаційної оцінки різними способами розрахунків показала, що при кількості 30 із різних асоціацій дає надійні результати, а 50 − надійність є високою. Поетапна маніпуляція із середніми значеннями, при порівняльному аналізі синтаксономічного складу на ландшафтному чи регіональному рівні, тобто оцінці β, γ-ценорізноманітності підвищує рівень достовірності апроксимації та полегшує візуалізацію отриманих результатів. На прикладах аналізу складного характеру кореляційних зв’язків між показниками екофакторів показано, що в окремих випадках поза критичними межами, точками біфуркації відбуваються якісні зміни, що свідчить про необхідність врахування лімітуючих значень при розробці прогностичних моделей. Зроблено висновок, що достовірність результатів. отриманих лише одним способом, не є достатньо надійною, а потребує перевірки іншим методом розрахунків або оцінки іншої вибірки даних. Наведені приклади свідчать про перспективність лінеаризаційного підходу в геоботанічних дослідженнях.

Published: November 2023

Проаналізовано видове різноманіття епігейних мохоподібних у лісових екосистемах Українського Розточчя та встановлено відмінності їх водного обміну і продуктивності залежно від умов локалітетів. Всього в епігейних угрупованнях визначено 48 видів мохоподібних, з них найбільшу кількість (33 види мохів та 2 види печіночників) – у зоні повного заповідання старовікових лісів. Збільшення кількості видів ксероморфних рудералів та поселенців у складі лісових мезоморфних угруповань є показником ступеня порушення лісових екосистем як природними, так і антропогенними чинниками. Стабільніші умови водного режиму і більший вміст вологи визначено у мохових рослинах та у ґрунті під ними на території букових старовікових лісів й насаджень сосни звичайної, порівняно з ділянками стаціонарної рекреації. Результати досліджень свідчать, що мохи лісових екосистем мали досить високий вміст хлорофілів та низькі показники (1,48–2,17) співвідношення Хл a/b, що вказує не лише на їх тіньовитривалість, а й на більшу адаптованість до широкого діапазону освітлення. Для домінантних лісових видів родини Polytrichaceae були зафіксовані найбільші показники фітомаси і фотосинтетичної продуктивності. У старовікових лісах фітомаса цих видів залежно від умов локалітетів досягала 337,55–784,57 г/м2, показники вмісту хлорофілів a+b змінювались в межах 3,82–4,61 мг/г маси сухої речовини, XI становив 1,27–7,87 г/м2. Дещо менші показники фітомаси (584,86–784,57 г/м2) визначено для субдомінантних видів роду Plagiomnium, показники вмісту хлорофілів a+b у яких становили 3,18–3,73 мг/г маси сухої речовини, а XI – 1,86–2,93 г/м2. На порушених ділянках для низькодернинних синузій мохів-поселенців і сланево-плетивних синузій за участю печіночників установлено невеликі показники наземної фітомаси асимілюючих пагонів (428,11–726,79 г/м2) та фотосинтетичної продуктивності (0,39–0,80 г/м2). Показники первинної продуктивності свідчать, що здатність бріофітного покриву до зв'язування атмосферного вуглецю має індикаційне значення для оцінки стану і функціональних особливостей лісових екосистем та залежить від видового складу бріосинузій, показників їх фітомаси, вмісту хлорофілів у різних умовах локалітетів.

Published: November 2023

Впродовж 2002–2023 років в урбанофлорі Київської міської агломерації сталися суттєві зміни: вона поповнилась 85 чужорідними видами з 63 родів і 43 родин, це здичавілі декоративні або бур’янові рослини. Переважна більшість їх ергазіофіти – 86%; крім 7 ксенофітів, 4 імовірно аборигенні види з прогресуючим типом ареалу, 1 раніше непомічений через низьку присутність, що разом становить близько 14%. Джерело поповнення – культивування рослин: озеленення, міське та аматорське квітникарство, інтродукційні центри тощо. Нестабільна складова новітнього елементу становить 79% (ефемерофіти – 33%, колонофіти – 46%). Ергазіофіти-ефемерофіти перебувають на імміграційному етапі стабілізації, триває формування повночленних нормальних популяцій, посилення присутності в просторі та утримання території. Зміни урбанофлори є зворотними, виявлені видовий і типологічний стан новітнього елементу вкрай сприятливі для запровадження превентивної системи раннього розпізнавання, вчасного реагування та запобігання негативному впливу чужорідних видів у межах Київської міської агломерації на аборигенні види, їх угруповання, біотичну різноманітність та якість життя.

¿Está el futuro de la energía relacionado con el hidrógeno?
Authors: Fermán Ávila Víctor Hugo , Núñez Caraveo Sergio Eduardo , Ochoa García Evelyn
Published: November 2023

En este artículo de reflexión pretendemos demostrar que definitivamente sí existe una relación muy cercana entre la energía y el hidrógeno, y que el hidrógeno está posicionándose como una alternativa viable para tomar el timón de las energías; de hecho, no sólo se trata de las energías renovables y limpias, sino de todo el mercado de la energía. Este artículo también comenta cómo la transición hacia ese uso del hidrógeno está siendo mucho más corta de lo que imaginábamos. Los países Latinoamericanos, con muy honrosas excepciones, sólo somos observadores de cómo Europa y los Estados Unidos ya están entrando en la etapa inicial, no sólo del desarrollo de las tecnologías basadas en el hidrógeno, sino en su aprovechamiento, con planes concretos tanto para el despliegue de tecnología tanto en celdas de combustible de hidrógeno, celdas de electrólisis, sistemas de recarga a alta presión, como de perspectivas de la evolución de mercado de esta energía.

Authors: Rahman Mohammad Ramzanur , Karim Mohammad Rezaul , Siddiki Mohammad Shohel Rana , Habib Raihan
Published: November 2023

Peda is a highly nutritious indigenous milk product of Bangladesh containing milk solids added sugar and other additive like cardamom powder. This experiment was conducted to test the feasibility of using mawa (dried milk) for making peda and also conducted to test the impact of sugar level on the quality of peda. Sugar, as traditional sweetener was used to make peda samples at the level of 0 g, 75 g, 150 g and 225 g. Peda samples were prepared with these different sugar ratios were analyzed for sensory attributes, chemical composition and microbiological quality. Analysis of the data for quality such as flavor, body and consistency, color and appearance and chemical analysis such as protein content, carbohydrate content, ash and total solids contents of peda samples revealed significant (P<0.05) difference, but there was no significant (P>0.05) differences for fat content and total viable count of peda samples. The organoleptic quality of 150 g sugar containing peda samples scored better result than control and other treatments. If overall quality aspects were considered, 150 g sugar containing peda samples gave best results than other samples.
