Mathematical Modelling and CFD Simulation for Oxygen Removal in a Multi-Function Gas-Liquid Contactor
Authors: Wang Mengdie , Nie Qianqian , Xie Guangyuan , Tan Zhongchao , Yu Hesheng
Published: June 2023

This paper presents and compares the mathematical models and computational fluid dynamics (CFD) models for degassing of oxygen from water in a laboratory-scale multi-function gas-liquid contactor under various operating conditions. The optimum correlations of the overall volumetric liquid-phase mass transfer coefficient (kLa) are determined by the mathematical models of specific contactors. Both the continuous-reactor model and semi-batch model can evaluate the degassing efficiency with relative errors within ±13%. Similarly, CFD models agree with experimental data with relative errors of ±10% or less. Overall, the mathematical models are deemed easy to use in engineering practice to assist the selection of efficient contactors and determine their optimum operation parameters. The CFD models have a wider applicability, and directly provide the local mass transfer details, making it appropriate for harsh industrial scenarios where empirical correlations for important quantities are unavailable. Combining these two types of models can effectively guide the design, optimization, and operation of the high-throughput degassing system.
Experimental Study on the Working Efficiency and Exergy Efficiency of the Vehicle-Mounted Thermoelectric Generator for Cold Chain Logistics Transportation Vehicle
Authors: Fu Yunchi , Li Yanzhe
Published: June 2023

This paper investigates a vehicle-mounted thermoelectric generator system working efficiency and exergy efficiency in a cold chain logistics transport vehicle (CLVTEG). The study examines the impact of factors such as load resistance, temperature difference, and copper foam on the performance of CLVTEG. Results demonstrate that adding copper foam significantly improves the output power of CLVTEG, with 40 PPI copper foam showing a 1.8 times increase compared to no copper foam. Additionally, copper foam enhances working and exergy efficiency, with 10 PPI copper foam achieving the best overall efficiency. The study also explores the effect of temperature difference on CLVTEGs efficiency, observing an initial increase followed by a decrease. Overall, this research underscores the importance of considering work and exergy efficiency when evaluating thermoelectric generators. Adding copper foam in the CLVTEG central area enhances heat transfer, resulting in improved efficiency. These findings offer valuable insights for optimizing the design and operation of thermoelectric generators in cold chain logistics transport vehicles.

Published: June 2023

Titanium is considered to be a biocompatible material and is used to a great extent in the pharmaceutical and oral implantology fields. While initially, specialists considered that its use does not cause adverse effects on the human body, as time has gone by, it has become clear that its use can lead to the development of certain diseases. The objective of this study was to identify the way in which digital technologies have the capacity to facilitate information regarding the potential long-term harm caused by titanium device toxicity during the COVID-19 pandemic. In this study, a regression model was developed to identify how a series of independent variables have the ability to influence the dependent variable (respondents’ perceptions of how new web technologies have the ability to help future physicians to facilitate information absorption with regard to potential titanium toxicity). The results illustrated that new technologies have the potential to support both the learning process on this topic and the innovation activity by discovering new solutions that will gradually lead to the reduction of the side effects of titanium used in the pharmaceutical and oral implantology fields.

Deep learning techniques are required for the analysis of synoptic (multi-band and multi-epoch) light curves in massive data of quasars, as expected from the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST). In this follow-up study, we introduce an upgraded version of a conditional neural process (CNP) embedded in a multi-step approach for the analysis of large data of quasars in the LSST Active Galactic Nuclei Scientific Collaboration data challenge database. We present a case study of a stratified set of u-band light curves for 283 quasars with very low variability ∼0.03. In this sample, the CNP average mean square error is found to be ∼5% (∼0.5 mag). Interestingly, besides similar levels of variability, there are indications that individual light curves show flare-like features. According to the preliminary structure–function analysis, these occurrences may be associated with microlensing events with larger time scales of 5–10 years.
High mountain trees: altitudinal records recently broken for eleven different tree species in Britain
Authors: Watts Sarah H.
Published: June 2023

In 2022 a project was initiated utilising citizen science to document observations of trees growing in Britain above 900 m. This focused recording effort contributed to eleven new altitudinal records for tree species in this country, including Sorbus aucuparia at 1150 m and Picea sitchensis at 1125 m (both East Inverness-shire, v.c.96). Some of these observations involved increases of at least 200 m above previous known altitudinal limits. The new records were a mix of small, stunted plants not expected to reach maturity in these extreme environments, as well as arctic-alpine Salix shrubs adapted to low temperatures and exposed conditions. Although these findings are currently too restricted to draw broad conclusions on the impacts of climate warming and land management on tree colonisation in mountain environments, long-term data collection may allow an analysis of drivers of change in the future. Out of a total of 72 tree records above 900 m collated by the author in 2022, 56% were Picea sitchensis, highlighting the ability of this neophyte to spread into high elevation habitats. The project has been useful for generating public interest in biological recording at and above the altitudinal treeline, and the continuation of such work will assist with mountain woodland restoration projects for a variety of ecologically important taxa and plant communities.
The wild Scots Pines (Pinus sylvestris) of Kielderhead

Published: June 2023

In the British Isles, Scots Pine (Pinus sylvestris L.) is currently considered to be native only in the Scottish Highlands. Once widespread throughout the archipelago, the species is thought to have declined to extinction outside the Scottish Highlands c.4500 cal BP, and c.1550 cal BP in Ireland. However, there have been discussions about whether some naturally occurring populations may have persisted outside the Highlands into modern times, and potentially may still be alive today. One such population is the enigmatic “Kielderhead Pines” in a remote valley just on the English side of the Scottish border at the heart of the c.60,000 ha Kielder Forest in Northumberland. Debate about the origins of this small population of apparently wild living pines has been ongoing since the 1950s, which has inspired the creation of the “Kielderhead Wildwood” to support its conservation and restoration. We outline the status, significance and the state-of-play in 2023 of our understanding of the origin of these trees, summarising research on the age of the trees, bioclimatic studies, possible botanical evidence of flora and lichen species typical of the Scottish pinewoods and genetics. We conclude that the explanation for the occurrence of the Kielderhead Pines - that they are locally native - remains a possibility, but we recognise and recommend that further research is required. We summarise the conservation efforts that have taken place to secure the pines within a landscape of restored, wild native upland woodland and mires i.e. re-creation of a Northumbrian equivalent of the Caledonian Forest. We also reflect on how the Kielderhead Pines support the case for greater consideration of the restoration of W18 pine woodland vegetation in appropriate locations outside the Scottish Highlands. We conclude by reflecting that one day these few pines, discovered in an isolated valley in Kielder Forest in the 1950s, may be seen as the start of something much bigger in the uplands of northern England, southern Scotland and beyond.
Were the five rare heathers of the west of Ireland introduced through human activity? An ecological, genetic, biogeographical and historical assessment
Authors: Sheehy Skeffington Micheline , Scott Nick
Published: June 2023

Five rare Irish heather species have different disjunct ‘Lusitanian’ type distributions in Europe. They are confined in Ireland to the western coastal region and found elsewhere only, or principally, in the Iberian Peninsula. Two also occur in Britain, but only in the extreme southwest. None could have survived the last ice age in Ireland, and migration northwards, leaving hundreds of kilometre gaps en route, appears impossible. We assemble here the growing evidence that Erica ciliaris L. (Dorset Heath), E. erigena R. Ross (Irish Heath), E. mackayana Bab. (Mackay’s Heath), E. vagans L. (Cornish Heath) and Daboecia cantabrica (Huds.) K. Koch (St Dabeoc’s Heath) have been introduced inadvertently through human activity, along with another heathland Lusitanian species Simethis mattiazzii (Kerry Lily), if over a long period. We suggest that the proximity to the coast of extensive heathland habitats in northern Spain and western Ireland along with the cutting of heathland for bedding and packing in Spain is a probable cause of their inadvertent carriage on a direct maritime trade route which dates from prehistorical times. By considering them together, we suggest that until a precise date for the earliest arrival in Ireland of each species is established, they should all now be considered as naturalised archaeophytes.

Published: June 2023

Infection remains an important cause of maternal and newborn morbidity and mortality globally despite evidence that it can be reduced with adherence to infection prevention and control (IPC) practices. The implementation of IPC has been especially challenging in rural health centres. This pilot study used a non-randomised quasi-experimental design to examine the impact of a low-cost intervention bundle at five rural health facilities in Southern Province of Zambia. We used the Infection Control Assessment Tool (ICAT) and surveyed the incharge nurse, observed deliveries and reviewed logbooks to collect pre- and post-intervention data on healthcare worker IPC practices and maternal and newborn outcomes. The intervention bundle included education sessions, provision of alcohol hand rubs (AHRs), short message service (SMS) text messages and poster reminders, and monthly study visits. The overall ICAT score did not significantly increase after the intervention (64.0 vs. 71.8, maximum score 133, P = 0.28). There was a significant increase in the labour and delivery practices module score (12.5 vs. 16.6, maximum score 27, P = 0.04) and a trend towards improvement in the hand hygiene module (9.1 vs. 13.6, maximum score 23, P = 0.08). There were no differences in pre- or post-intervention outcomes amongst the 654 mothers who delivered and the 655 newborns during the study period. In conclusion, a low-cost bundle of interventions did neither overall improve healthcare workers’ IPC practices in rural Zambia nor significantly change the rates of newborn and maternal complications. Identified challenges included inconsistent supplies of AHRs, protective and sterile equipment, as well as heavy workload for healthcare workers, which inhibited preventative behaviours.

Datasets of text images are important for optical text recognition systems. Such datasets can be used to enhance performance and recognition rates. In this research work, we present a bilingual dataset consists of Arabic/English text images to address the lack of availability of bilingual text databases. The presented dataset consists of 97812 text images, which are categorized into two groups; Scanned page and digitized line images. Images of the two forms are written with 10 fonts and four sizes, and prepared/scanned with four dpi resolutions. The dataset preparation process includes text collection, text editing, image construction, and image processing. The dataset can be used in optical text recognition, optical font recognition, language identification, and segmentation. Different text recognition and language identification experiments have been conducted using images of the dataset and Hidden Markov Model (HMM) classifier. For the digitized images recognition experiments, the best-achieved recognition correctness is 99.01% and the best accuracy is 99.01%. The font that has the highest recognition rates was Tahoma. For the scanned images recognition experiments, Tahoma has also shown the highest performance with 97.86% for correctness and 97.73% for accuracy. For the language identification experiments, Tahoma has shown the performance with 99.98% for word-language identification rate.
Spatial Pyramid Pooling and Adaptively Feature Fusion based Yolov3 for Traffic Sign Detection
Authors: Li Bin , Xiong Shimin , Zhu Shiao , Cui Dongfei , Song Xiaonan
Published: June 2023

Traffic sign detection is a key part of intelligent assisted driving, but also a challenging task due to the small size and different scales of objects in foreground and closed range. In this paper, we propose a new traffic sign detection scheme: Spatial Pyramid Pooling and Adaptively Spatial Feature Fusion based Yolov3 (SPP and ASFF-Yolov3). In order to integrate the target detail features and environment context features in the feature extraction stage of Yolov3 network, the Spatial Pyramid Pooling module is introduced into the pyramid network of Yolov3. Additionally, Adaptively Spatial Feature Fusion module is added to the target detection phase of the pyramid network of Yolov3 to avoid the interference of different scale features with the process of gradient calculation. Experimental results show the effectiveness of the proposed SPP and ASFF-Yolov3 network, which achieves better detection results than the original Yolov3 network. It can archive real-time inference speed despite inferior to the original Yolov3 network. The proposed scheme will add an option to the solutions of traffic sign detection with real-time inference speed and effective detection results.

Published: June 2023

Gas-liquid two-phase flow is widely involved in many scientific and technological fields, such as energy, electricity, nuclear energy, aerospace and environmental protection. In some fields, extracting the accurate position of bubbles in space can not only accurately capture the characteristics of bubbles in two-phase flow, but also plays an important role in the subsequent research like bubble tracking. It has got some progresses to use Convolutional Neural Network (CNNs) to identify bubbles in gas-liquid two-phase flow, while accurate pixel segmentation map in the bubble identification problem is more desirable in many areas. In this paper, VGG16-FCN model and U-Net model are utilized to identify bubbles in two-phase flow images from the perspective of semantic segmentation. LabelMe is used to label the images in the experiment, which can remove the noise in the original image. In addition, bubble pixels with low ratio relative to the background affects the loss function value tinily which cause the irrational evaluation for the recognition in traditional semantic segmentation, thus, Dice loss is used as the loss function for training to improve the recognition effect. The research results show that the two deep learning models have strong feature extraction ability and accurately detect the bubble boundary.

Electrical energy has become a basic need for humans today, almost all aspects of human life require electrical energy. The electrical energy needed so far has been produced from fossil energy which is not environmentally friendly and has dwindling reserves, alternative energy is needed which is environmentally friendly and sustainable. Energy that can be utilized includes water energy, wind energy, solar energy and so on. The sun is one of the abundant energy, by crossing the equator, Indonesia has enormous energy reserves. This potential is expected to become Indonesia's future energy. Currently solar cell technology is very advanced with increasingly good efficiency, in addition to energy conversion by solar cells with photovoltaic technology, a method is needed to store the results of the conversion into storage (batteries) optimally. One of the battery charging technologies is the Pulse Width Modulation (PWM) method, with this method battery charging is optimal on a 50 WP solar panel. In this study, a 50 WP solar panel was used, a 28 Ah 12 Volt battery, a 10 Watt Dc 12 Volt load and a 10 Ampere PWM Solar Charger Controller (SCC). The system was running for 3 months from September to December, the load was turned on for 12 hours every day with a load absorption current of 0.9 Amperes. Every day the current used is 10.8 Amperes. For 3 months the weather was not always stable, so charging was less than optimal, but until now the system is running well with an average after usage voltage of 12.3 Volts.

Позиционный нистагм чаще всего возникает вследствие заболевания внутреннего уха – доброкачественного пароксизмального позиционного головокружения (ДППГ). Диагноз устанавливается на основании жалоб и анамнеза пациента, а также выявления характерного нистагма. Несоответствие характеристик нистагма ожидаемым при ДППГ требует исключения других причин позиционного головокружения, в том числе центрального позиционного синдрома. В статье приведен разбор основных характеристик центрального и периферического позиционного нистагма. Описываются основные заболевания, которые могут проявляться позиционным синдромом, а также критерии дифференциальной диагностики центрального и периферического позиционного головокружения. Описан клинический пример центрального позиционного синдрома при вестибулярной мигрени, которая скрывалась под маской доброкачественного пароксизмального позиционного головокружения горизонтального полукружного канала (геотропного типа), а также наш опыт лечения пациентов с мигрень-ассоциированным головокружением. Наглядно объясняется важность сбора анамнеза и правильности оценки результатов, полученных при проведении диагностических позиционных тестов, чтобы не пропустить под маской доброкачественного пароксизмального позиционного синдрома заболевания центральной нервной системы.

The discrepancy between the characteristics of nystagmus expected in BPPV requires the exclusion of other causes of positional vertigo, including central positional syndrome. The article presents an analysis of the main characteristics of central and peripheral positional nystagmus. The main diseases that can manifest as positional syndrome are described, as well as criteria for differential diagnosis of central and peripheral positional vertigo. A clinical example of central positional syndrome in vestibular migraine, which was hiding under the mask of benign paroxysmal positional vertigo of the horizontal semicircular channel (geotropic type), is described, and our experience in treating patients with migraine-associated vertigo is presented. The importance of collecting anamnesis and the correctness of evaluating the results obtained during diagnostic positional tests is clearly explained, in order not to miss the diseases of the central nervous system under the guise of benign paroxysmal positional syndrome.
PROGRAM ORIENTATION OF MUNICIPAL BUDGETS
Authors:   University of National and World Economy, Bulgaria, Borisov Borislav
Published: June 2023

The purpose of the article is to show the necessity of developing program-oriented municipal budgets. The view of different authors on the subject is presented, as well as good practices of other countries. The existing practice of developing strategic documents and budgets in Bulgarian municipalities is described. A sociological survey was made of the opinion of business organizations as partners of local authorities, regarding their participation in the budget process and in the development of strategic documents for the development of municipalities. The results show a rather skeptical attitude towards the possibilities of business organizations to influence local policies and the development of budgets. A proposal is made in the national legislation and in the local normative base of the municipalities to establish the requirement for coordination of the strategies, plans and programs developed at the municipal level with the annual budgets. Program budgeting at the municipal level is not only possible, but also imperative, due to its efficiency, transparency, opportunity for wider citizen participation in the budget process and in the development and implementation of local policies.
THE MESSAGES IN COMMUNICATION - WHY DON’T WE UNDERSTAND EACH OTHER

Published: June 2023

The introduction of rules in a given field is related to the setting of certain requirements to the products, processes or bodies that implement them and aims to ensure a certain quality. This is generally the case, but it also applies in full force to the communication process. The existence of strict rules in communication presupposes the setting of specific requirements regarding the necessary knowledge, professional skills and competencies that communicators must possess in order to achieve the desired effect, striving for professional growth and career in their organizations. In the process of communication information, emotions, feelings, ideas are exchanged. Assuming the communicators are professionally trained - then why don’t they understand each other? We will try to get to the reason in this post. For the purposes of the research, fundamental scientific formulations and methods of the theory of the nature of communications, comparative analysis, as well as examples from the speeches of celebrities in public space (media and social networks) - were used. Communication between people can be characterized as interpersonal if it meets the following criteria: it involves a certain number of people in immediate interaction; participants have the opportunity to see, hear, easily provide feedback. It is assumed that each of the participants understands, perceives and influences the other side, respects the arguments of their partner. Communication implies investment of emotions, competence of the parties in relation to the established rules, possession of a certain intelligence, which is the basis of the management of emotions - emotional intelligence. It includes self-control skills, personal and social competence, motivation and delegation skills, conflict resolution, empathy and hope. It is indisputable that the skills and abilities necessary in the process of communication and the manifestation of intelligence are found in a different proportion in each one. Emotions are a starting point for personality development, they face challenges, give everyday life more depth and meaning. Emotions require intelligence, they must be harnessed to facilitate achievement. Anyone can learn to be intelligent about their emotions and apply that intelligence to solving many of life’s problems. To achieve excellence in this field, knowledge and development of certain skills are required. Defining feelings makes it possible to study their nature and control them. There is no great human good without great emotion, because feelings have taught mankind to reason. Differences in religious, cultural and political beliefs are often the cause of tragic and fatal separation. The feelings manifested in sympathy and compassion, empathy and pain, all have the ability to unite.

Sharia banking is one of the nation's economic solutions, this is because economic activity is the backbone of the driving force for national stability, then at this time national economic activities must be started moving towards a sharia-based economy. The development of Islamic banking in Indonesia has resulted in a merger or merger of 3 (three) existing Islamic banks, namely Bank Syariah Mandiri (BSM), Bank Negara Indonesia Syariah (BNIS) and Bank Rakyat Indonesia Syariah (BRIS). The definition of a merger is a process of merging two companies, where one of them remains standing by using the name of the company, while the other company disappears and all of its assets are put into the company that remains standing. There are several types of mergers, including horizontal, vertical and conglomerate mergers. Each merger has its own characteristics. Horizontal merger is a process of merging between two or more companies, where the type of business of the company is still the same. As is happening in the banking industry, of course, the merger is carried out because there are certain goals and reasons to be achieved. Based on some of the problems above, the researcher wants to conduct research on what are the effects or impacts of the merger of three BUMN Sharia Banks on the development of the Islamic economy in Indonesia.

Published: June 2023

Accurate dataset classification is a critical task in various domains, and combining different methodologies can enhance classification performance. This research presents a novel approach that integrates Hybrid Grid Partition and Rough Set methods for fuzzy rule generation, aiming to improve accuracy and interpretability in dataset classification. The proposed approach leverages Hybrid Grid Partition to discretize continuous attributes and Rough Set attribute reduction to identify essential attributes, enabling accurate classification while handling uncertainty and imprecision. The generated fuzzy rules provide interpretability, aiding decision-making processes and providing insights into classification factors. The approach's robustness and generalization capabilities are demonstrated through experiments on diverse datasets, indicating its potential applicability in real-world scenarios. However, limitations such as the absence of specific evaluation metrics and the need for further validation on larger datasets are acknowledged. Overall, this research contributes to accurate dataset classification by offering a novel integrated approach and highlighting areas for future investigation and refinement

Published: June 2023

This research presents a novel approach for optimizing dataset classification through the integration of a hybrid grid partition and rough set method for fuzzy rule generation. The objective is to improve classification accuracy and interpretability while effectively handling uncertainty in the dataset. The proposed approach combines grid partitioning, rough set theory, and fuzzy logic to identify relevant attributes within each grid cell, generate accurate fuzzy rules, and perform classification based on fuzzy inference. The research demonstrates the improved accuracy of the hybrid approach compared to traditional methods, along with enhanced interpretability of the generated fuzzy rules. The scalability and generalizability of the approach are validated through its application to a case example in customer churn prediction in the telecommunications industry. However, certain limitations, such as the selection of the partitioning scheme, computational complexity, and handling of missing data, need to be considered. Further research is required to address these limitations and benchmark the approach against state-of-the-art techniques. The proposed hybrid approach contributes to the field of dataset classification by offering an effective and interpretable methodology for improved classification performance and actionable insights in real-world applications

The objectives of this study were to determine the extraction yield and phytochemical composition of different Artemisia herba-alba (AHA) extracts, as well as to investigate in-vitro their antioxidant, anti-inflammatory, anti-glycation, and antibacterial activities. Four solvents with different polarities were used to prepare AHA extracts. The extraction yield was determined using the gravimetric method. The qualitative analysis was performed using the standard methods. The quantitative analysis, the antioxidant, and the anti-inflammatory activities were estimated using the colorimetric method. The anti-glycation activity was measured using the spectrofluorimetric method. The antibacterial activity was performed using an agar diffusion method. Our findings showed that 80% aqueous ethanolic extract significantly (p ≤ 0.05) compared to other extracts exhibited high extraction yield (15.3%), high phytochemical content (263.93±2.46 mg GAE/g E for total phenols), (40.94±1.45 mg QE /g E for total flavonoids), and (35.99±1.20 mg GAE/g E for total tannins), better Diphenyl-2-Picrylhydrazyl (DPPH) radical scavenging capacity (IC50 = 4.13±0.02 mg/mL) with no significant differences (p ≤ 0.05) when compared to methanolic extract, as well as high anti-glycation activity (IC50 = 3.96±0.09 mg/mL). The methanolic extract had a significant inhibitory effect against the majority of the tested bacteria ccompared to other extracts. The anti-inflammatory potential of distilled water extract was significantly (p ≤0.05) higher (IC50 = 2.96±0.06 mg/mL) compared to the rest yet failed to show any antimicrobial activity against all assayed bacteria. In summary, the solvent type had a significant effect on the chemical and biological characteristics of AHA. The diversity and significance of Artemisia herba-alba’s biological activities demonstrate its potential application within the pharmaceutical and food areas.
