Authors: Sis Jose  , Apoorwa Nawrathan Kothari  , Rashmi Rani  , Usha Ramakrishna Sastry  , Deepa Baskaran  , Arpana Kedlaya
Published: May 2024

Background: Fentanyl-induced cough (FIC) is an undesirable side effect associated with intravenous injection of the opioid fentanyl, which can lead to an increase in intraocular, intrathoracic, and intraabdominal pressures. The incidence of FIC is reported to be 18–65%, more common in young females, who are also at high risk population for post-operative nausea and vomiting (PONV). FIC and PONV are both common anesthesia-related events that seem to have common risk factors.
Aims and Objectives: The objectives of the study were to find out the incidence of FIC in female patients undergoing elective surgery under general anesthesia and if FIC was a risk factor for developing PONV.
Materials and Methods: A randomized, prospective study was done to compare the incidence of FIC and its correlation with PONV. 263 adult female patients belonging to American Society of Anesthesiologists status I and II, aged 18–59 years, posted for elective surgery under general anesthesia were studied over a period of 2 years. Pre-operatively, fentanyl (2 mg/kg body weight) was injected intravenously over 10 s as premedication, and the occurrence of any episode of cough within 60 s of fentanyl administration was taken as FIC. The incidence and severity of PONV were assessed in the same study population for a 24-h period. The incidence of FIC during general anesthesia in the study population was noted, and its correlation with PONV was analyzed.
Results: The incidence of FIC in the study population was found to be 27%. The incidence of PONV in the FIC group was found to be 38%, as compared to 29.7% in the non-FIC group. FIC group had a higher incidence of PONV than the non-FIC group, but it was statistically insignificant (P=0.254).
Conclusion: The incidence of PONV was slightly higher in the FIC group than in the non-FIC group, but it was not statistically significant.

Published: May 2024

Background: Metabolic liver diseases (MLDs) in children can present with a wide range of clinical features.
Aims and Objectives: This study aims to increase the high index of suspicion among physicians and awareness among caregivers regarding early diagnosis of MLD.
Materials and Methods: This hospital-based prospective observational study has been conducted in the Paediatric Outpatient Department and Inpatient Department of RG Kar Medical College, Kolkata, over 2 years from 2021 to 2023. A total of 47 children aged up to 12 years were diagnosed as various MLDs who fulfilled inclusion and exclusion criteria were included in the study. Template was generated and analysis was done on SPSS software.
Results: The study sample was 47 children with MLDs. Mean age was 4.21±3.81 years. Males: female ratio was approximately 2.35:1. History of consanguinity among parents was present in 23.40% cases which affirmed the autosomal recessive mode of inheritance in most of the MLD. History of sibling deaths was there in 10 cases. The most common symptom was yellowish discoloration 21 (44.68%) followed by abdominal distension 12 (25.53%). There were diverse modes of presentations. The most common presentations were hepatomegaly 47 (100%) and splenomegaly 30 (63.83%). Of 47 MLDs, Wilson disease cases were maximum (27.66%) followed by glycogen storage disease (23.40%).

Published: May 2024

Background: The World Health Organization states that cervical carcinoma is the fourth most common cancer among women worldwide. Pap smear is the simplest and easiest test to detect this prevalent cancer at its nascent stages.
Aims and Objectives: This study aims to evaluate Pap smears using the conventional method (Bethesda 2014) and correlate the abnormal smears with cervical biopsy.
Materials and Methods: The study is a combined retrospective and prospective study, from January 2021 to August 2023. Pap smears received were evaluated according to Bethesda 2014. Those cases categorized as Epithelial Cell Abnormality (ECA), were correlated with corresponding histopathology on cervical biopsy.
Results: Out of the 615 pap smears in this study, 525 cases (91%) were categorized as Negative for Intraepithelial Lesion or Malignancy, 53 cases (9%) as Epithelial Cell Abnormality, and 37 cases (6%) as unsatisfactory. In the Negative for Intraepithelial Lesion or Malignancy category, 353 cases (67.2%) were reactive cellular changes including inflammation, four cases (0.7%) were squamous metaplasia, and 24 cases (4.6%) were atrophic smears. In the ECA category–21 cases (39.6%) were Atypical squamous cells of undetermined significance, two cases (3.8%) were Low-grade squamous intraepithelial lesion, five cases (9.4%) were Atypical squamous cells-cannot exclude HSIL(ASC-H), 14 cases (26.4%) were High grade squamous intraepithelial lesion (HSIL) and 3 cases (5.6%) were squamous cell carcinoma (SCC) cervix, seven cases were of ECA-glandular type (13.2%). On histopathological correlation, the maximum correlation was found for HSIL and SCC cases, 71% and 100%, respectively.
Conclusion: Pap smear is a crucial screening tool to diagnose cervical carcinoma at its nascent stage. This study showed a positive correlation for high-grade lesions on Pap smears.

Authors: Ambarish Ghosh  , Maidul Islam SK  , Raghav Oza
Published: May 2024

In recent years, screen time exposure and attention-deficit hyperactivity disorder (ADHD) symptom interrelations in children have garnered increasing attention. Understanding the screen time’s impact on ADHD has become crucial due to its potential influence on socialization, neurobehavioral development, and the prevalence of ADHD among pediatric populations. Conforming to the guidelines of the preferred reporting items for systematic reviews and meta-analyses, a systematic examination was undertaken, centering on research investigating the correlation between screen time and ADHD symptoms in children. The search encompassed databases including MEDLINE (through PubMed), ScienceDirect, Wiley online library, PsycINFO, ERIC, JSTOR, and PsycArticles, utilizing descriptors such as “screen time” and “attention-deficit hyperactivity disorder.” The initial search yielded 2480 articles, supplemented by an additional 10 articles from reference searches, resulting in a total of 2480 records. Excluding the duplicates, 1590 articles were screened based on abstracts, of which 130 underwent full-text examination. Ultimately, 15 studies included in this review met the inclusion criteria. These studies, conducted between 2013 and 2023, comprised cross-sectional, longitudinal, and interventional designs, presenting varying associations between screen time and ADHD symptoms across different age groups. The findings from the selected studies depict a complex relationship between screen time exposure and ADHD symptoms in children. While some studies highlight significant correlations between increased screen exposure and ADHD symptoms, others present conflicting results, indicating the need for further research. Understanding these nuances is crucial in formulating targeted interventions and delineating clearer guidelines to manage screen time concerning ADHD in children.

Authors: Sathya Jagdish  , Kiruthiga T  , Shruthi Prashanth  , Jaya Vijayaraghavan  , Sinduja Thirumanagalam Palanisamy
Published: May 2024

Background: Hypertensive disorders of pregnancy are becoming the leading cause of maternal morbidity and mortality worldwide and are responsible for 9–25% of deaths 1. They are believed to occur due to an imbalance between pro-angiogenic factors, like placental growth factor (PlGF) and anti-angiogenic factors, like soluble fms-like tyrosine kinase-1 (sFLT-1).
Aims and Objectives: The aim of the study was to evaluate the role of the sFLT-1/PlGF ratio along with uterine artery Doppler for the prediction of pre-eclampsia (PE).
Materials and Methods: The current study was a prospective case–control study conducted at Sri Ramachandra Medical College and Hospital, Chennai, from 2018 to 2020. Blood samples for sFLT-1 and PlGF and uterine artery Doppler were done in 100 pregnant mothers who are at 16–20-week gestation attending antenatal outpatient department in the Department of Obstetrics and Gynecology.
Results: We found that the mean sFLT-1 in high-risk group was 826.17 ng/L (standard deviation [SD]±251.31) compared to 924.69 ng/L (SD±360.61) in low-risk groups. The mean PlGF in the high-risk group was 23.07 ng/L (SD±4.68) compared to 27.43 ng/L (SD±5.62) in low-risk group. The mean sFLT-1/PlGF ratio was increased in high-risk group of about 39.68 (SD±22.77) compared to 35 (SD±16.98) in low-risk group. Women with high resistance uterine artery Doppler have 8.5 odds of getting PE compared to those with normal uterine artery Doppler.
Conclusion: According to our study, the sFLT-1/PlGF ratio carries more sensitivity (90%) and negative predictive value (74.19%) if we keep the value as 32.25 along with uterine Doppler rather than their individual values for the prediction of PE.
Cutaneous manifestations of hypothyroidism: An observational study in a tertiary care center of Eastern India
Authors: Swastika Debbarma  , Aniruddha Ghosh
Published: May 2024

Background: Changes in skin, hair, and nails may be initial manifestations of an underlying thyroid hormone deficiency. Symptomatic treatment of cutaneous manifestations without treatment of underlying hypothyroidism contributes to long-term morbidity in patients.
Aims and Objectives: The aim of the study was to study the cutaneous manifestations and demographic profile of patients with hypothyroidism.
Materials and Methods: We conducted a hospital-based cross-sectional study of 200 patients presenting with cutaneous changes in primary hypothyroidism for a period of 18 months. A detailed history, clinical examination, and relevant investigations were performed.
Results: Out of 200 patients, cutaneous manifestations were more prevalent in the age group between 30 and 49 years. The ratio of male to female was 1.0:6.4. A family history of hypothyroidism was present in 34.5% of patients. The most common cutaneous features were alteration in skin texture (53.0%), dry skin (48.5%), generalized pruritus (42.5%), urticaria (17%), followed by pigmentation of the skin (34.5%), out of which vitiligo was 9.0%, melasma was 5.5%, and others were 20.0%. Other changes include xerosis (32.5%), eczematous disorder (13%), acquired palmoplantar keratoderma (11.5%), and brittle nails (3.5%). 39.5% had hair changes, out of which diffuse hair loss was 17.5%, coarse hair wa s 12%, alopecia areata was 4.5%, and lateral loss of eyebrows was 4.5%. Changes in the oral cavity and mucous membrane were present in 3.0% of the patients, which included lip vitiligo (1.5%), oral lichen planus (1%), and oral candidiasis (0.5%). Menstrual abnormalities were present in 50.84% of females. The percentage of hypothyroid patients who complained of easy fatigability, facial puffiness, cold intolerance, weight gain, constipation, neck swelling, hoarseness of voice, increased sleeping pattern, and non-pitting edema of feet were 38.5%, 36.5%, 26.0%, 23.5%, 17.0%, 9%, 8%, 7.5%, and 6.5%, respectively.
Conclusion: Based on our study, it can be concluded that the presence of certain skin conditions, such as alteration in skin texture, dry skin, generalized pruritus, urticaria, skin pigmentation, and diffuse hair loss, may indicate the possibility of hypothyroidism. These cutaneous manifestations may occur earlier than the diagnosis of hypothyroidism through biochemical testing. Therefore, it is important to consider the possibility of hypothyroidism when examining patients with these skin conditions.

RESEARCH OF ECONOMIC SUSTAINABILITY AS THE BASIS OF ENSURING ECONOMIC SECURITY AT THE MICRO LEVEL
Authors:   Odessa National Maritime University, Zahorodnia Karina , Khotyeyeva Natalia
Published: May 2024

The article is devoted to the study of the economic sustainability and economic security of an enterprise in the conditions of multiple external environment.In the conditions of instability of the external environment of enterprises, the problems of ensuring their economic stability and adaptability acquire priority importance. Ensuring the economic stability of the enterprise is a guarantee of viability and the basis of stable economic development, competitive position and competitive advantages in the market. It gives priority in attracting investments, obtaining loans, choosing contractors and attracting qualified personnel. The higher the economic stability of the enterprise, the higher its adaptability, independence from changes in the market and, therefore, the lower the probability of bankruptcy.It is proven that the economic security of the enterprise largely depends on the component of economic stability, solvency, liquidity, profitability. It is indisputable that economic sustainability is the basis of enterprise security and the ability to implement development strategies in conditions of minimizing the impact of risks, threats and dangers. It was noted that the effectiveness of the relationship and mutual influence of the economic stability and security of the enterprise is reflected in its financial flexibility based on the ability to change the volume and structure of funding sources, as well as the directions of investment of financial resources due to the influence of risks, threats, dangers of the internal and external environment.Therefore, without ensuring the economic stability of their enterprises in the conditions of a market economy, enterprises will not be able to operate successfully on the market. The modern market is constantly changing. Since changes are happening quickly, adapting to them becomes a significant advantage of enterprises in the fight against competitors.
Policies for Other People: Reflections from an Economist on Research and Federal Policy Regarding Indigenous Nations in Canada after 1975
Authors: Feir Donn L.
Published: May 2024

Comment les gouvernements colonisateurs établissent-ils des politiques relatives aux peuples et aux nations autochtones? Une façon de faire est de répondre à la recherche. Cependant, la recherche est aussi influencée par les politiques publiques et les narratifs sociaux qui les sous-tendent. Dans le présent article, je me penche sur la documentation publiée dans la plus importante publication sur les politiques publiques du Canada, Analyse de politiques, depuis 1975 et sur des articles publiés dans des revues économiques pour mieux comprendre l’état actuel du dialogue sur les politiques publiques au Canada, comme créé par la présente revue et des économistes. Moins de 3 % de tous les articles d’ Analyse de politiques depuis sa création jusqu'au présent numéro traitent de contextes autochtones. Le pourcentage est encore plus bas dans les 400 principales revues économiques, avec 21 articles. La majorité de cette documentation est axée sur l’éducation et les marchés du travail ou sur l'autonomie gouvernementale ou les droits des autochtones, ces derniers étant beaucoup plus présents après l'an 2000. Je discute de ces deux volets de documentation et je confirme les résultats des articles sur le marché du travail avec des données plus récentes. À l'examen de la documentation, il est devenu clair qu'il reste encore beaucoup à faire pour que la recherche reflète la pleine réalité économique des nations autochtones et pour que les politiques tiennent compte de la vie économique autochtone.

Note des rédacteurs : Le premier volume de Canadian Public Policy/Analyse de politiques a été publié en 1975. Ce volume-ci est le cinquantième. Pour commémorer cet événement, nous avons organisé une série de conférences qui sont publiées dans ce numéro spécial. Dr. Feir a donné cette conférence dans la portion virtuelle des réunions de l'Association canadienne d’économique en mai 2023.

El acceso abierto y los repositorios son aspectos cruciales para la difusión de los resultados científicos. A pesar de los avances de todos estos años, existen retos para una implantación total del modelo abierto que han quedado evidenciados en la reciente convocatoria de sexenios 2023 en España, en la que se sumaba el requisito de depositar en abierto las publicaciones. Este escenario ha incrementado la demanda de orientación en bibliotecas por parte de la comunidad, revelando al mismo tiempo desconocimiento y errores en el depósito. Esta nota pretende en primer lugar enfatizar la importancia de los repositorios, en especial los repositorios institucionales, para asegurar la preservación y maximizar la disponibilidad de las publicaciones científicas. En segundo lugar ofrece directrices para una implementación efectiva del acceso abierto, resaltando la elección de repositorios, atención a políticas editoriales, y la gestión adecuada de metadatos. Pues a la vista de estos nuevos requerimientos enfrentamos una oportunidad única para fortalecer la investigación y contribuir al acceso abierto, siempre que se realice correctamente.
THE IMBALANCE OF POWER
Authors: Brightman Marc
Published: May 2024

Amerindian societies have an iconic status in classical political thought. For Montaigne, Hobbes, Locke, Hume and Rousseau, the native American ‘state of nature’ operates as a foil for the European polity. Challenging this tradition, The Imbalance of Power demonstrates ethnographically that the Carib speaking indigenous societies of the Guiana region of Amazonia do not fit conventional characterizations of ‘simple’ political units with ‘egalitarian’ political ideologies and ‘harmonious’ relationships with nature. Marc Brightman builds a persuasive and original theory of Amerindian politics: far from balanced and egalitarian, Carib societies are rife with tension and difference; but this imbalance conditions social dynamism and a distinctive mode of cohesion. The Imbalance of Power is based on the author’s fieldwork in partnership with Vanessa Grotti, who is working on a companion volume entitled Living with the Enemy: First Contacts and the Making of Christian Bodies in Amazonia.

Authors: Ikram Hira , Umer Aiman , Kashif Muhammad , Rehman Bushra , Saleh Zada Numan , Islam Khan Sanam
Published: May 2024

In the current work, we used molecular approaches to collect and characterise bacteria that produce amylase from soil. Based on clear zones, three species were separated using iodine agar plates. Then, these bacterial isolates were characterised by 16S rRNA gene sequencing. Based on 16S rRNA analysis, the bacterial isolates were identified as Bacillus cerus, Bacillus subtilis, and Bacillus stratosphericus. In addition, numerous growth parameters were tuned to produce the most amylase possible. For both 24 and 48 hours, the isolates' maximum optical density for growth was seen at pH 7.0. Compared to nitrogen and peptone, all three of the bacterial isolates produced the greatest amount of amylase when maltose was utilised as the carbon source. Further investigation is needed to determine which novel isolates in this site have the highest amylase activity. Our findings indicate that this enzyme has a variety of potential industrial applications.

Стаття розглядає різні моделі фінансування інновацій, що існують у сучасному українському бізнес-середовищі, аналізуючи їх переваги та недоліки. Автор детально описує кілька основних джерел фінансування: внутрішні кошти підприємств, банківське кредитування, венчурне фінансування, державне фінансування та краудфандинг. В контексті кожного джерела оцінюється його роль у підтримці інновацій, а також визначаються основні виклики та перспективи для розвитку. Особлива увага приділяється венчурному фінансуванню та його впливу на розвиток стартапів у галузі високих технологій. Автор підкреслює важливість державної підтримки інноваційних проектів та роль краудфандингу як інноваційного методу залучення коштів, що дозволяє підприємцям тестувати ринковий попит і залучати широку аудиторію до фінансування своїх ідей. Стаття висвітлює не тільки поточний стан справ у сфері фінансування інновацій в Україні, але й пропонує рекомендації щодо оптимізації існуючих моделей і розвитку нових підходів, з метою підвищення ефективності та залучення додаткових ресурсів для підтримки інноваційної активності. Стаття акцентує увагу на необхідності адаптації українських компаній до змінюваних умов глобалізації, швидкого технологічного прогресу та зростаючої конкуренції на міжнародних ринках. Окремо варто відзначити аспекти синергії між різними джерелами фінансування та їхнє потенційне поєднання для досягнення кращих результатів в інноваційних проектах. Наприклад, можливість комбінування державних субсидій із венчурними інвестиціями або використання краудфандингових кампаній для залучення додаткового фінансування та перевірки ринкової валідації продуктів. У підсумку, стаття наголошує на імперативі розробки комплексної державної політики у сфері інновацій, яка б включала податкові стимули, фінансові інструменти та регуляторні рамки, що сприятимуть розвитку інноваційної екосистеми. Автор закликає до створення умов, які не лише допоможуть українським компаніям виживати, але й процвітати в епоху технологічних змін.

Groundwater: Sinking Cities, Urbanisation, Global Drying, Population Growth
Authors: Pattison John Edward , Cooke Peter
Published: May 2024

An examination of a few examples of aquifer-use shows the importance and fragility of groundwater, with poor management leading to over-extraction by individuals and authorities producing subsidence – sinking cities. Freshwater is one of our most precious resources and it is rapidly disappearing, leading to global drying. At the same time, the global and urban populations are increasing, with civil unrest increasing due, in part, to freshwater shortages. The increasing global population and global urbanisation are driving an increase in water use, restriction of aquifer recharge and increased aquifer pollution. It is argued that urban population growth with attendant increased water use, combined with climate change and poor management, is significant in water stress. Particular attention must be paid to the effect of rising populations on local water resources, especially groundwater, and the knock-on effect on urban sustainability.

Authors: Jiang Zhaozhuang , Zhu Yan , Du Juan , Sun Shihao
Published: May 2024

Aiming at the problem of the limited load of automated guided vehicle (AGV) used in logistics transportation, design a simple structure, safe and reliable AGV frame. The frame adopts seesaw structure to reduce the deviation of center of gravity, so that it can bear large load, and analyze its performance. The three-dimensional modeling of the AGV frame was created with SOLIDWORKS software and imported into HYPERWORKS for static analysis of full-load bending conditions, full-load bending and torsion conditions, emergency braking conditions, and emergency turning conditions to determine whether the strength and stiffness of the AGV frame meet the requirements, and according to the results of simulation for structural optimization. Then, the vibration characteristics of the frame structure were determined by free modal analysis through HYPERWORKS. The maximum stress and displacement of the AGV frame under four working conditions are obtained. Among which, the full-load bending and torsion condition is the most unfavorable. The maximum stress is 236.6MPa, which does not exceed the yield limit (343 MPa) of the material 16MnL. The maximum deformation is 1.413mm, which is within the allowable range. The natural frequency of the frame is between 10-46Hz, which belongs to the low-frequency range. The strength and stiffness of the AGV frame designed in this paper meet the requirements when the load is 3 tons, and there is no resonance phenomenon with the road surface. At the same time, it also provides certain ideas and reference value for designing other types of frames.

Published: May 2024

This manuscript introduces a novel framework and algorithm that leverages inertial sensors to capture and optimize data on human joint motion posture, thereby enhancing the accuracy and stability of contemporary motion capture technology. By wirelessly transmitting nine-axis motion data from joint-worn inertial sensor nodes to a host computer, real-time visualization of motion attitude data is achieved through software. Moreover, the acquired data is effectively denoised through a two-stage extended Kalman filter algorithm. Subsequently, the feasibility of capturing motion attitude using the inertial nodes, as well as the effectiveness of the proposed algorithm, is empirically validated through single-node experiments, substantially elevating the overall stability of the system.
Research on Coal-Rock Recognition Based on the EMD-EM-BP Model
Authors: Tian Shengyu , Tian Ying , Wang Yang , Gu Jieying
Published: May 2024

This article presents a coal-rock recognition method based on a BP neural network. It involves testing acoustic emission (AE) signals during the shearing and cutting of coal-rock, analyzing coal-rock characteristics, and applying Empirical Mode Decomposition (EMD) to the AE signals to obtain several Intrinsic Mode Functions (IMFs). Energy moments of the IMFs, with significant correlation coefficients, are then extracted. These energy moments serve as inputs for the BP neural network to identify the acoustic emission signals of coal-rock. Experimental results indicate that after using the EMD algorithm to decompose the AE signals and calculate the energy moments of the IMFs in relation to the original AE signals, distinctive features become apparent. The BP neural network achieves a high accuracy rate of 95% in recognizing coal-rock characteristics. This model offers exceptional recognition precision and lays the theoretical and technological groundwork for realizing automated and intelligent mining in fully mechanized mining operations.

Relevance. The great potential for the development of the agricultural industry in the Russian Federation necessitates the study of factors influencing it. In the current crisis conditions of economic development, this direction will help identify the causes of the development of agricultural crises, make timely management decisions related to minimizing the consequences of their negative impact and rapid economic recovery. The purpose of the study is to analyze the factors of agricultural activity that can reflect the impact of instability and economic crises on the development of the agricultural sector. Methods. The methods of normalized sliding standard deviation, a model of multiple linear regression, a forecasting method based on the ARIMA model, and the Granger causality test were used. Scientific novelty. For the first time in Russian practice, the volatility of agricultural indicators was assessed, the links between these indicators and shocks in financial markets were revealed. Results. A statistical relationship between the volume of agricultural production and instability factors has been modeled, showing that 87.5 % of the variation in agricultural production can be explained by variations in variables – water, labor. The causality test showed that instability in the agricultural sector is the reason for the volatility of the RTS index, the index of industrial production. The growth of agricultural production is predicted for all three forecasting scenarios. The most likely (optimal) scenario showed an increase in production volumes to 9806,9 billion rubles by the end of 2023, to 10 707,1 billion rubles by the end of 2024 and to 11 605,1 billion rubles by the end of 2025. It is concluded that financial shocks cause an increase in volatility in agricultural markets.

New regularities have been discovered in the synthesis of polymer ionic liquids and ionene-type ionic liquids based on polyionenes derived from tetrahydro-1,4-oxazine. The methods for regulating the molecular weight of the synthesized polymers have been improved by varying the nature and composition of the solvent, as well as the concentration of the starting monomers. These improvements have resulted in the creation of new and promising materials. For the first time, we investigated the effects of temperature, solvent type and composition, chemical structure, and concentration of polyionenes derived from tetrahydro-1,4-oxazine on their behavior in water and water-ethanol solutions, as well as the shape of macromolecules in different solvents. Newly synthesized polymeric ionic liquids and ionene ionic liquids with an ionic conductivity of 10–2–10–5 S•cm–1 and a glass transition temperature range of –1500С–150С exhibit five to six orders of magnitude higher ionic conductivity compared to known analogues.

Liquefied petroleum gas (LPG) is one of the common fossil fuels that can be derived from natural gas or crude oil. In either case, it contains impurities such as H2S and CO2, which should be removed to obtain sweet liquified petroleum gas with a pure concentration of hydrocarbons such as ethane, propane, and butane. The most common method of gas sweetening process is by using amine compounds, which come in various types, each designed for specific and selective removal of acidic gases. In this study, methyldiethanolamine (42 wt.%) was used as a solvent to extract approximately 0.8% of H2S from sour LPG at a temperature of 400C. The objective of this study focuses on simulating and optimizing the LPG sweetening unit using Aspen HYSYS V11 to investigate the different parameters that affect the separation of acidic gases and to achieve high profitability. The number of trays, circulation rates, temperature, mass and molar flow rates, and other parameters were studied to reduce the H2S concentration to 0% in the treated LPG stream. The sweetening process was proposed to produce LPG with high levels of specific preferred specifications such as calorific value and purity, in addition to being environmentally friendly.

The optical characteristics of glasses have become an increasingly established and developing aspect. This article presents the optical characteristics of the Ln3+ ion in lead sodium fluoroborate glass, which has the composition 10 PbO–19 NaF–70 B2O3–1.0 Ln2O3 (where Ln=Eu and Tb, all in mol.%). Glass samples were processed using the conventional melt-quenched approach, and the glassy nature was confirmed by the X-ray diffraction patterns. The optical absorption spectra of PbO–NaF–B2O3 glasses with Eu3+ ions exhibit distinct absorption bands that were assigned to the transitions 7F05L6, 5D3, 5D2, and 7F15D1. Judd-Ofelt (JO) factors (2, 4, 6) were determined from the absorption spectra. By using least square fit analysis, oscillator strength (f) was evaluated and presented. Regarding the three J-O parameters (2, 4 and 6), 2, that is related to structural adjustments in the area of the Ln3+ ion, indicates slow adjustments of the covalent surroundings.

The article reveals the trends and risks of digitalization, which today is the main factor in the formation of a new society. Digitalization is seen as the high point of the globalization process. Digital technologies have increased the effects of globalization, weakening the factors that hinder interstate economic interaction, which has become a determinant of the growth in the share of international trade in national economies, thereby increasing the degree of interdependence of states, international integration and the role of large private companies in international trade. Digitization as a complex and multifaceted phenomenon is of particular importance, since the developed global level of the technological process and the prevalence of digital technologies led to the active involvement of people in the online environment. And although the states are at different stages, we can affirmatively talk about the last stage at which the population of the planet is, having reached the global scale of digital technologies. The acquired level of distribution and use of digital technologies indicates the formation of a digital space, the structure of which consists of computer technologies, mobile devices and other means of virtual and augmented reality, in which communication between users is deployed, the movement of information flows takes place, as well as production, distribution, exchange and consumption of digital goods and other types of social interaction. The digital space is the main source of formation of the digital economy and contains all its processes and elements. Modern society is in the thick of digitalization. In almost all areas of social life, we find a wide array of different practices that are subject to digital change. The Internet and social media platforms have changed how we receive information and experience entertainment, socialize, shop, and present ourselves. We develop and are confronted with new digital business models that are based on the “new gold” of user and process data. Apps and “smart” machines are designed to make sense of these data in order to automatically understand patterns or to control industrial processes in the context of Industry 4.0 (the Fourth Industrial Revolution). Algorithms, autonomous vacuum cleaners, cars or weapons and humanoid robots are in different stages of development and implementation. All of these manifestations and practices are obviously connected to questions of digital security, democracy, and how politics and legislation deal with these new phenomena of digitalization.
