Authors: Shaikh Sultana , Jain Vandana
Published: May 2023

Objective: To develop a novel, accurate, precise and linear reverse phase high performance liquid chromatographic (RP-HPLC) method for simultaneous qualitative and quantitative estimation of quercetin, ellagic acid and rutin in an ayurvedic formulation and validate as per international conference on harmonization (ICH) guidelines.Methods: In the present work, good chromatographic separation was achieved isocratically using a shim-pack HPLC C18 column (4.6 x 250 mm, 5Î¼m) and a mobile phase consisting of 0.02 M potassium dihydrogen orthophosphate buffer (pH adjusted to 3 with orthophosphoric acid) and methanol in the ratio 55:45, at flow rate of 1 ml/min and column temperature maintained at 35 Â°C. The effluents obtained were monitored at 254 nm with a UV-visible detector.Results: The retention time of quercetin, ellagic acid and rutin were found to be 7.52 min, 9.10 min and 12.47 min respectively. Linearity of quercetin, ellagic acid and rutin were found in the range of 8-12 ppm, 9-17 ppm and 7-11 ppm respectively. The correlation coefficient for quercetin, ellagic acid and rutin were 0.997, 0.999 and 0.999 respectively. The high recovery values (98 %-102 %) indicate a satisfactory accuracy. The low percent relative standard deviation (% RSD) values in the precision study reveal that the method is precise.Conclusion: The developed method is novel, simple, precise, rapid, accurate and reproducible for simultaneous quantitative estimation of quercetin, ellagic acid and rutin in an ayurvedic formulation. Hence the developed method can be used for quantitative analysis and quality control of extracts and commercial samples of other plant species and formulation containing these three markers.

The Philippines is a major provider of seafarers, with the majority of Filipino sailors serving on merchant ships all around the world. To stay competitive in the global market, most shipping companies recruit maritime students through a variety of processes and provide them with the necessary knowledge, expertise, and skills. The experience of maritime cadets/cadettes in the workplace aids them in realizing and grasping the employment needs onboard merchant vessels. This quantitative research study assessed the onboard experiences of PMMA cadets in order to improve the academy's shipboard training program and policy. A researcher-made survey questionnaire via Google form was used to gather data from the 162 First Class cadets/cadettes who were graduating midshipmen of S.Y. 2020-2021. The study found out that the cadet-trainees were exposed to technical tasks during their shipboard training. In terms of challenges onboard, they never at all experienced sexual and verbal harassment and abuse. Accordingly, they have very low experience related to civic disengagement. Inculcating high tolerance in shipboard training related to work stress and condition is one of the strengths of the PMMA Shipboard Training Program and the assignment and availability of training officers on board was noted as one of its weaknesses.

Published: May 2023

Abstract: Kidney stones play a role in the development of chronic kidney disease. Recurrent kidney stones should be avoided not only because of their immediate clinical manifestations but also because of their long-term predisposition to CKD progression. A lot of people confess to emergency departments with excruciating pain due to kidney stones, which are prevalent ailments around the world. The diagnosis of kidney stone illness involves the use of many imaging modalities. For the entire diagnosis and interpretation of these photos, specialists are required. Systems for computer-aided diagnosis are useful methods that can be utilized as supplemental tools to aid clinicians in their diagnosis. The deep learning (DL) technique, which has lately achieved considerable advancements in the field of artificial intelligence, is offered in this work as a means of automating the detection of kidney stones (containing stones or not) using coronal computed tomography (CT) scans. Different cross-sectional CT images were taken for every individual, resulting in a total of 1453 images. Using CT scans, we have seen that even little kidney stones are accurately detected by our model. This study demonstrates that other difficult urological problems can be addressed using newly popular DL approaches

The Soviet East European Policy in the Arabic Press on the Eve of the World War II (August — December 1939)
Authors: Mitryashkin A. S.
Published: May 2023

This paper analyzes Arabic newspaper and magazine publications devoted to the assessment of the USSR foreign policy towards the East European countries after the signing of the Soviet-German non-aggression treaty of August 23, 1939. The article presents the opinions of Arab journalists and writers about the prerequisites and consequences of the signing of the so-called «Molotov-Ribbentrop Pact», the peculiarities of relations between Moscow and Berlin in the end of 1939, the reasons for the invasion of the Red Army in Poland, as well as the motives that prompted the Soviet leadership to strengthen its presence in the Baltic region. It is concluded that many authoritative Arabic newspapers and magazines, despite a dependence on the Western European information agenda, sought to independently comprehend the actions of the Soviet government in different parts of Europe, sometimes even emphasizing the forced nature of an aggressive and ultimatum policy. At the same time, it is impossible to talk about the existence of a dominant position on this problem. Arab authors frequently criticized the military and political actions of the Soviet government in the autumn-winter of 1939. It should be added that the volume and number of articles published in the press testify to the true interest of the Middle Eastern publics in the state of affairs in the distant Soviet Union.

Published: May 2023

One of the key drivers of the Indonesian economy is small and medium-sized enterprises (SMEs). Especially in overcoming the crisis caused by COVID-19. However, SMEs also need a competitive advantage to be able to compete with larger companies. One of the competitive advantages can be obtained through innovation in eco-design (Vihma & Moora, 2020). This study examines the factors which influence SMEs’ intention to adopt eco-design. The quadruple bottom line (QBL) method forms the foundation for these elements (Simons et al., 2017). It is the evolution of the triple bottom line (TBL) with the additional factor of purpose, besides three existing factors: people, planet, and profit. In addition, using the theoretical framework of planned behavior and social cognitive theory, we also investigate the variables that affect purpose. In this work, structural equation modeling partial least squares is used as a quantitative method. A questionnaire is used to gather the primary data, SMART PLS 3 software is used for data processing, and SME entrepreneurs are selected as respondents. According to the findings, attitude, and self-efficacy significantly influenced purpose. People, planet, and purpose influence SMEs’ intention to adopt eco-design.

Published: May 2023

This research explores how increased gender diversity on corporate boards in Iceland, driven by applying a “hard” public policy, i.e., board gender quota legislation, has affected post-quota board directors’ perceptions of board functioning. This study falls into the growing literature on board diversity (Boshanna, 2021; Li et al., 2020). Directors’ opinions towards board decision-making and monitoring activities are researched, as well as their effect on corporate governance practices. A survey was answered by 244 board directors in Iceland. Results show that the initial attitude towards gender quotas was more negative among male directors than female directors but became more similar and positive over time. Strong support is found for increased female board participation leading to different viewpoints being discussed at the board table in addition to better decision-making. A similar picture emerges regarding the behavior of holding chief executive officers (CEOs) accountable and being more focused on corporate governance practices. These results were significantly the view of female directors and directors chairing the assessed board. Male directors are more negative than their female counterparts about the short term effect of increased female participation is having on board dynamics. This research indicates that a gender quota has led to increased female board participation in addition to impacting decision-making corporate norms, according to directors, as policymakers intended.
MANAGING AGILE PROJECTS FROM THE VIEWPOINT OF EVOLVING CAPACITIES
Authors: Shah Wasim Fathima , Srivastava Sarthak
Published: May 2023

Businesses have increasingly prioritised the introduction of
ground-breaking new products in recent years as a means of
differentiating themselves from the competition. As a result, several
businesses have begun adopting agile project management practises rather
than traditional waterfall methods. Iterative, or “agile,” project
management has emerged, was spurred by the need for a more adaptable
approach to product creation that would allow businesses to more quickly
and easily provide creative goods that would both delight their
consumers and generate a profit. As a result, agile project management
was developed as an alternate to conventional methods, which frequently
entail rigid procedures that must be modified whenever a new requirement
arises. The author examines the link between agile project management
and new product development in this work. The paper’s case study and
findings show that innovation may be realised through the use of agile
management, user participation in the development process, competent
team members, effective management, and cutting-edge tools. Many
recommendations were made, all of which may be followed by businesses in
order to be creative and to attain high levels of customer happiness.
This was done in order to support the agile principles.

Published: May 2023

The recent investigation was to ascertain whether europinidin could
defend rats against scopolamine- tempted deficits in learning and
memory. Wistar rats were arbitrarily separated into four clusters and
treated as follows: Cluster 1 (normal control) and Cluster 2
(scopolamine-SCOP) received oral administration of 3 ml/kg of 0.5%
sodium CMC (vehicle). Clusters 3 and 4 received europinidin (p.o. lower
dose-10 and higher-20 mg/kg, respectively) for a 14-day period. The
ability to move spontaneously, recall information, and learn were
assessed in rats for 15-day, animals were placed for euthanasia, and
analyzed for acetylcholine esterase (AChE), choline acetyltransferase
(ChAT), antioxidant (CAT, SOD, GSH, and MDA), nitrites,
anti-inflammatory (TNF-α, IL-1β, IL-6, and IL-10) and brain-derived
neurotrophic factor (BDNF). SCOP caused the animals to lose their
memory. SCOP altered the activities of AChE and ChAT, decreased GSH,
SOD, and CAT quantity attenuated the levels of IL-10, BDNF, and improved
levels of MDA, nitrate, IL-1β, IL-6, and TNF-α in brain tissue.
Europinidin effectively reduced the neurobehavioral deficits, oxidative
stress, and neuroinflammatory markers affected by SCOP in the treated
rats as well as reverted the AChE, ChAT, and BDNF levels back to normal,
europinidin lessens the reminiscence impairment affected by scopolamine
in rats.

Published: May 2023

Flowering phenology of alpine plant communities and seasonal dynamics of
flower visitors have been scarcely studied in the tropical/subtropical
alpine regions. We report flowering phenology, flower production, and
flower-visiting insects in the alpine site of central Taiwan. Throughout
the research period (2017–2018), we recorded flowering phenology of 130
plant species, flower production of 81 species, and 15,127 insects
visiting alpine flowers. Most of the alpine plants were visited by
dipteran insects and/or hymenopteran insects. The seasonal patterns of
flowering were more apparent in bee-visited plants compared to
fly-visited plants in which the flowering of bee-visited plants clearly
increased as the season progressed. About 63% of flower visitors were
dipteran insects (syrphid and non-syrphid flies), and 30% were
hymenopteran insects (mostly bumble-bee workers). Although the seasonal
trend in fly abundance was less clear between years, bumble-bee
abundance consistently increased in the middle to late seasons,
reflecting colony development. There was a positive correlation between
bee abundance and the number of flowering species of bee-visited plants,
but there was no correlation between fly abundance and the number of
flowering species of fly-visited plants throughout the season. These
results suggest that the flowering phenology of subtropical alpine
communities is influenced by the seasonal availability of pollinators.
Bumble bees, syrphid flies, and non-syrphid flies had wide ranges of
foraging flowers, but their niche overlap was relatively small. Because
cold-adapted bumble bees are threatened by climate change in Taiwan,
plant–pollinator interactions may be disturbed by global warming.
Study on Optimization Methods for Production Processes of Composite Insulator Sheath and Core Rod
Authors: Luo Haowen , Yang Jihao , Zhang Sida , Liu Yunfan , Cheng Li , Li Siwei
Published: May 2023

Water diffusion significantly contributes to abnormal temperature rise
in composite insulators. At the same time, the material performance
defect caused by the composite insulator production process can further
increase moisture intrusion. To propose optimized heating measures for
composite insulators from the material itself, this paper conducts
research on the ingredient process of composite insulator sheath and the
production process of composite insulator core rods, respectively. We
establish the water absorption model of aluminium hydroxide particles
and the penetration model of epoxy resin. Then we identified that the
flame retardant particle size is a factor that affects the water
absorption of the sheath, while epoxy resin liquid viscosity and fibre
volume fraction are factors that affect the porosity of the core rod in
the process. Water absorption experiments are conducted to verify the
positive correlation between the particle size of flame retardant and
the saturated water absorption rate of the sheath. Our porosity testing
has confirmed that low-viscosity liquids and high-fibre volume fraction
can reduce the porosity of the core rod. Based on these findings, we
propose heat generation optimization measures for the sheath and core
rod from a process perspective.
Influences of fluid velocities and solid properties on the thermal behavior of microchannel reforming reactors
Authors: Chen Junjie
Published: May 2023

The present study relates to hydrogen production in a microchannel
reactor by steam-methanol reforming on copper-based catalysts. Hydrogen
is produced by steam reforming methanol in a reactor which is shaped
much like a conventional shell and tube heat exchanger except that the
tubes contain catalysts. Calculations are performed using computational
fluid dynamics and chemical kinetics to investigate the hydrogen
production and thermal transport processes in a heat integrated
microchannel reactor by steam-methanol reforming. The change of thermal
energy in the reactor is fully described in order to analyze the
influences of fluid velocities and solid properties on the thermal
behavior of the reactor. The results indicate that a sufficient reaction
rate is crucial for the complete conversion of the hydrocarbons on the
catalyst. In order to increase the hydrogen content of the synthesis gas
produced by the steam methane reforming process, the synthesis gas can
be subjected to water-gas shift reactions to react residual steam in the
synthesis gas with the carbon monoxide. Reformer tube failures are
typically associated with high metal temperatures. Preferably, the size
and shape of the catalyst pellets and the shape of the metal foam
particles are similar. At smaller excess-air factors, the increase in
temperature in the entry zone of the reactor is less pronounced. Because
of the requirement of reactor compactness, the number of burners is kept
at a minimum.

Opportunities and Challenges in Applying Machine Learning for Access Control
Authors: Nakamura Sora , Tanaka Yuto
Published: May 2023

Access control systems are important in regulating who can access physical facilities , computer systems, and data resources. However, traditional access control systems have limitations in adapting to changing user behavior and evolving security threats. We argue that applying machine learning is a promising direction to access control systems can enhance their accuracy, efficiency, and effectiveness. Machine learning can help identify and mitigate security risks in real-time by detecting patterns of suspicious activity that may indicate a security breach or attempted attack. It can also learn to identify anomalies and raise alerts, enabling security personnel to respond quickly and prevent potential security incidents.

The current stage of development of Ukraine's international relations with other countries requires a revision of the foreign language teaching process in higher school. Special emphasis should be paid to the effectiveness of foreign language learning. The expansion of international contacts highlights the need for training a specialist who can communicate with representatives of other countries not only at the domestic level, but also in professional activities. First of all, this concerns specialists in those professions in which there is intercultural communication (international internships, participation in international conferences). The English learning process of many Ukrainian medical colleges and universities is mainly based on non-authentic materials. Few studies have been conducted to explore the implications of authentic and non-authentic materials in learning English for Specific Purposes (ESP), for medicine in particular. The current study explores students’ perception of these resources in learning medical English. In order to optimize the learning process, a comparative analysis of English language manuals for medical professionals was made. The data were obtained on the basis of a questionnaire filled out by medical students of two universities. The students were required to assess different aspects of both authentic and non-authentic materials. The ultimate goal of the analysis is to determine the educational efficiency of the afore-mentioned textbooks and the students’ motivation for English learning. Analyzing the effectiveness of training future medical specialists for professional communication, the following methods were used: descriptive, statistical and empirical methods: observation, testing, and questionnaires. The findings showed that the participants had positive attitudes toward using authentic resources and that they preferred them to non-authentic ones. Authentic resources provide a beneficial effect on the development of students’ language skills in their professional area. The prospects of further studying in the in-depth analysis of different ways of optimizing English language proficiency.
Meaning differences between English clippings and their source words: A corpus-based study
Authors: Hilpert Martin , Saavedra David Correia , Rains Jennifer
Published: May 2023

This paper uses corpus data and methods of distributional semantics in order to study English clippings such as dorm (< dormitory), memo (< memorandum), or quake (< earthquake). We investigate whether systematic meaning differences between clippings and their source words can be detected. The analysis is based on a sample of 50 English clippings. Each of the clippings is represented by a concordance of 100 examples in context that were gathered from the Corpus of Contemporary American English. We compare clippings and their source words both at the aggregate level and in terms of comparisons between individual clippings and their source words. The data show that clippings tend to be used in contexts that represent involved text production, which aligns with the idea that clipped words signal familiarity with their referents. It is further observed that individual clippings and their source words partly diverge in their distributional profiles, reflecting both overlap and differences with regard to their meanings. We interpret these findings against the theoretical background of Construction Grammar and specifically the Principle of No Synonymy.
