Published: April 2024

Abstract. Metrology has been a slowly digitalizing field in which a significant part of the handling of data has been dependent on paper-based processes. Due to the need for the improved efficiency and reliability of these processes, digitalization has become a major topic of interest in the metrology community. Data formats such as the digital calibration certificate (DCC) have an essential role as an enabler of further digitalization, acting as the harmonized data format for calibration data. Naturally, introducing these data formats into industrial usage sets new requirements with respect to the calibration management and associated systems. Diversity of metrology also means that the systems need to be flexible and scalable to fulfill the needs of actors in the global calibration infrastructure with very different requirements. This paper presents a conceptual approach for enhancing the communications between the existing systems in a calibration ecosystem and enabling DCC-based data exchange with third-party systems using the Beamex calibration ecosystem as an example. Thus, the presented system architecture concept that introduces data and DCC exchange services would provide a solution to enable the use of DCCs on Beamex systems.

Abstract. The presence of exceptionally old ice and relative ease of access make Antarctic blue-ice areas (BIAs) attractive paleoclimate archives. However, only a handful of BIAs, mostly situated in West Antarctica and along the Transantarctic Mountains, have been investigated for this purpose. Here, we present the age of surface ice from the Grove Mountains BIA in Princess Elizabeth Land, East Antarctica, determined by measuring 81Kr in the trapped air. Two samples yield an average age of 143-29+33 kyr. Together with the reported terrestrial age of a chondrite, we conclude that the Grove Mountains BIA holds considerable potential for paleoclimate studies.
Algorithmic recommendation as repair work: Towards a more just distribution of attention on cultural and entertainment digital platforms
Authors:   , Bartolo Louisa
Published: April 2024

Scholars, civil society groups and regulators have highlighted various risks associated with the digital ‘nudging’ of human attention by platform companies’ recommender systems. In this thesis, I focus on the risks of these systems encoding and re-entrenching social inequality: under-representing, or harmfully misrepresenting, (members of) historically marginalised social identity groups. I empirically examine patterns in the recommendation of history books on Amazon and the representation of transgender streamers in homepage recommendation on Twitch. I then develop a framework for reimagining algorithmic recommendation as a tool to elevate the voices of those historically excluded from participation in public spaces and conversations.

Published: April 2024

Rice milling process refers to the removal of husk and bran layers from the paddy grain. Proper machine settings in relation to physical and engineering properties of paddy are necessary for efficient milling operations. The present research work was aimed at incorporating modifications in a rice rubber roll sheller of modern rice mill for better control on its operation. A microcontroller-based electronic device was developed to quantify the clearance between the rubber rolls and feed opening of the rubber roll sheller. The values were displayed on seven-segment display units. A mechanical system to suit automation was also developed to automatically control the feed rate of feed hopper of the rubber roll sheller. The device was designed to read from 0 - 72 mm feed opening gap with least count of 0.075 mm, and rolls clearance from 0 mm to 21 mm with least count of 0.01 mm.

Published: April 2024

In the context of intensive water consumption patterns emanating from urbanization and accelerated economic growth, water footprint (WF) has been recognized as comprehensive measure to promote efficient, equitable and sustainable use of water resources. In the present study, the WF of a river basin was assessed and blue, green and grey water footprints of major water-consuming sectors of agriculture, domestic and industry within the Betwa river basin were quantified. Sustainability of the blue and grey WFs were analysed to identify temporal hotspots wherein water consumption and pollution infringed upon environment flow requirements. Total annual WF of the Betwa river basin was estimated as 9186 Mm3 . Agricultural sector was the largest water consumer accounting for 96.4 % of the total WF, followed by the industrial and domestic sectors (2.2 %). The WF of rainfed and irrigated agriculture was 3868 and 4986 Mm3 , respectively. The comparable proportions of blue (45.5 %) and green (43.6 %) WFs in total WF highlighted equal dependence on rainfall, surface water and groundwater resources. The study demonstrated that consumption-based approach of WF provided more realistic estimates of the water uses at river basin scale. Higher values of sustainability indicators like Blue Water Scarcity Index (>400 during December, January and February) and Water Pollution Index (>135 during January and February) indicated that the pattern of human consumption of blue water and resultant pollution was encroaching into environmental flows within the Betwa river basin.

Authors: S. J. Kale  , S. K. Jha  , Prerna Nath
Published: April 2024

Pusa Basmati 1121 (PB1121) rice (longest milled grain in the world), raw and parboiled, was dehusked and milled at 6 different degrees of milling (DOM) varied from 5-10 per cent. Head rice yield decreased up to 10% with increased DOM in both raw and parboiled rice. However, parboiling increased the yield of marketable rice by 18.68 per cent. DOM significantly (α=0.05) affected cooking and textural qualities of raw and parboiled rice. Mineral composition of raw and parboiled rice indicated that P, K, Mg and S constituted the major portion, about 97% of the mineral composition of PB1121 rice. DOM adversely affected the mineral content of rice, but this effect was less severe in parboiled rice. Principal component analysis (PCA) performed for selected quality characteristics of PB1121 rice indicated that optimum DOM (%) for raw and parboiled PB1121 rice would be 7% and 8%, respectively.

Surgical stapling has evolved significantly over time, with the primary goal of improving patient outcomes. This study describes the technological advancements in surgical stapling from the perspective of staple and cartridge design, assessing the impact of staple design when it changes from the traditional B form (also known as 2D staple form) to a three-dimensional form (known as 3D staple form). The change in configuration helps compress a larger surface area of the tissue. The 3D configuration is designed to optimize compression not only underneath each staple but also across staples and multiple staple lines, including both stapled and unstapled regions of the tissue. By achieving more evenly distributed compression throughout the staple line, there is potential for reduced leak paths. The study demonstrates that the 3D staple form in surgical stapling results in more evenly distributed compression. In the future, this advanced technology should seamlessly integrate into emerging systems such as the surgical robot, enabling continued progress in surgical instrumentation and ultimately in surgical care.

Background: Female cosmetic genital surgery is becoming increasingly sought after by women who are concerned with the appearance of their vulva. Labiaplasty for the labia minora is undoubtedly the most commonly performed female cosmetic genital surgery. However, an increasing number of patients seen in our clinics in both Brazil and the United States are presenting with clitoral hypertrophy, specifically clitoral elongation. The elongated clitoris will usually protrude beyond the labia minora and majora and from the patient’s perspective will give a less feminine appearance as they will often describe the protruding clitoris as feeling like they have a small penis. The surgical technique described here, Batalha Clitoropexy, is a minimally invasive surgical technique for clitoral length-reduction that does not require amputation or debulking. This technique is presented in the form of the detailed sequential steps needed to achieve satisfactory results. Photos taken before and after the procedure in a representative case show that the clitoral length has been shortened from 5.0 cm to 1.5 cm without the need of an invasive amputation or debulking clitoroplasty. Many patients with clitoromegaly or an elongated protruding clitoris do not need to undergo an invasive clitoroplasty. Specifically, patients with clitoral elongation or clitoral ptosis can be surgically treated with a less-invasive clitoropexy surgical procedure which can restore normal anatomic position to treat a protruding clitoris.

The formation of colloidal species of fullerene C60 in two component (xylenedimethylformamide) organic solvents was studied for the first time. The results of the study of the refractive index and UV-visible spectra of C60 solutions were accompanied by an analysis of the particle size using the dynamic light scattering (DLS) method. A correlation has been established between the change in the refractive index of the solution and the degree of selforganization of fullerene molecules in solution at different concentrations and storage periods. It is shown that in the xylene-dimethylformamide binary system, the absorption spectra of C60 (~0.22 mg/ml) do not retain spectral features in a pure solvents when the solution is stored after 5 days. It has been established that, over time, the C60-xylene-dimethylformamide solution becomes polydisperse, and the sizes of the resulting fullerene nanoaggregates depend on the initial C60 concentration.

Published: April 2024

Rapidly developing antibiotic resistance limits the capabilities of veterinary specialists and doctors in the fight against infectious diseases. Effective diagnosis and continuous improvement in the field of antimicrobial therapy is the main approach in the treatment and prevention of bacterial infections. According to available data, bacteria are able to develop resistance in 2-3 years, while it takes an average of 5 years to develop and test a new antimicrobial drug. In our study, bacteriological examination of samples of pathological material from cows from 10 livestock farms in different districts of the Leningrad region was carried out, followed by determination of the sensitivity of isolated crops to antibiotics. In this study, 84 samples from cows were selected and examined and 115 cultures of microorganisms were isolated. As a result of the bacteriological study of the pathological material from cows, 9 groups and types of pathogenic and opportunistic microorganisms were identified. The main proportion is detected on staphylococci – 35.7%, mainly Staphylococcus aureus, epidermal staphylococcus and citrus staphylococcus. Escherichia coli (23.5%) and Proteus vulgaris (20.9%) were among the microorganisms in terms of frequency of occurrence. Most of the isolated cultures had average sensitivity to gentamicin, enrofloxacin, ciprofloxacin, ceftriaxone, cefepim, cefotaxime, neomecin; resistant to doxycycline, amoxicillin, levofloxacin, colistin, doxycycline, streptomycin, tylosin, tetracycline.

Published: April 2024

L-carnitine is a vitamin-like substance that plays an important role in the transport of fatty acids and their further use as an energy source. Most studies have identified beneficial effects of using L-carnitine for preventive and therapeutic purposes. The series of publications reviewed is devoted to the study of the results of the use of L-carnitine in metabolic disorders, diseases of various organs, organ systems, the central nervous system, as well as to elucidate the possible reasons for the decrease in the level of L-carnitine in the body. To date, L-carnitine is used in the Russian Federation only in the form of a feed additive; the purpose of our study was to study L-carnitine in the form of an injection solution. Toxicity studies were conducted on outbred rats in October 2021 in the vivarium of the St. Petersburg State University of Veterinary Medicine. The study involved females weighing 190-210 grams. When studying subchronic toxicity when administered intra-muscularly, L-carnitine was administered at 2 dose levels. 1/5 and 1/10 of the maximum tolerated dose in acute toxicity studies. In this regard, three groups of animals were formed. The first experimental group (n=10) was administered the drug intramuscularly at a dose of 0.08 mg/kg, the second group (n=10) at a dose of 0.04 mg/kg. The control group (n=10) was intramuscularly injected with a 0.09% sodium chloride solution at a dose of 0.08 mg/kg. The study was carried out over 42 days. Biological material samples were taken from 5 animals from each group the next day after the end of the drug administration (day 43), and 10 days after the last drug administration (day 53). The results of the study showed that dosages of 1/5 and 1/10 of the maximum tolerated do not cause external signs of toxicosis and death in rats. No significant changes were found in the biochemical parameters of the blood of animals in the experimental and control groups.

The structure of groups plays an important role in the study of the nature of the groups. We examine some basic properties and structural characteristics of the dihedral group of degree n, where n is a natural number, by group-theoretic approach. We begin the exploration by providing a foundational understanding of dihedral groups, elucidating their definitions and essential properties. Furthermore, we investigated the algebraic and geometric aspects of these groups, highlighting their role in describing symmetries of n-gons and other mathematical entities. Special attention is given to the distinctive features that differentiate dihedral groups from other algebraic structures. The analytic expressions for the order of subgroups are obtained and the commutativity investigated. The groups are all represented for further analysis and applications.
Theoretical Study of Forced Van Der Pol Oscillator Equation Using Multiple Two-timing Regular Parameter Perturbation and Asymptotic Expansion Techniques
Authors: N.O. Onuoha
Published: April 2024

This paper presents the theoretical study of forced Van der Pol oscillator equation. Oscillatory systems are studied to know measures that can reduce the amplitude of oscillation of the oscillatory system. Here, multiple two-timing regular parameter perturbation is applied since it is a kind of perturbation among other perturbation techniques that enables the study of the behaviour of a system under certain conditions. Asymptotic expansion technique was also applied. Excel Microsoft was used to analyse the uniformly valid asymptotic solution of the Van der Pol oscillator equation obtained. The uniformly valid asymptotic solution in the independent variable obtained, showed that damping alters the amplitude of the oscillatory system thereby affecting its motion. Increase in damping decreases the amplitude of oscillation of the system. With damping incorporated in the system though very small damping, the amplitude of oscillation reduces with time.

Published: April 2024

The generation of flow data allows the assessment of the capacity to meet water demands, predict floods, and estimate the potential for hydraulic exploitation for electrical energy generation. In Brazil, precipitation data series, due to their ease of measurement, are more extensive compared to flow data series, enabling the use of hydrological models called rainfall-runoff models capable of estimating flows from precipitation data. Therefore, utilizing the Brazil Gridded Meteorological Data (BR-DWGD) database, this study aims to generate, calibrate, and validate flow data for the Piauitinga river basin located in the state of Sergipe, Brazil, using the monthly rainfall-runoff SMAP model. The soil parameters considered in the validation for the studied region showed a good fit to the observed data, achieving a Nash-Sutcliffe (NS) of 84% and log-Nash-Sutcliffe (NSLog) of 85% in calibration, and Nash-Sutcliffe (NS) of 70% and a log-Nash-Sutcliffe (NSLog) of 80% in validation. Therefore, since the rainfall-runoff model used exhibited good performance for the studied hydrographic basin, it becomes feasible to use the generated synthetic series to fill possible gaps in the historical series of monthly average flows.

The main objective of this research is to evaluate the impact of food and nutritional education strategies on symptoms associated with intestinal dysbiosis in women. For the methodological search, a qualitative research approach was conducted, of the integrative literature review type. Data collection took place in scientific databases: LILACS and PUBMED. The results obtained suggest that food and nutritional education plays a crucial role in modulating the intestinal microbiota. Nutritional education strategies can provide women with information about how to choose foods rich in fiber, prebiotics and probiotics, which promote intestinal health. Nutritional guidance can help women avoid processed foods high in sugar and saturated fat, which are known to harm the microbiota. However, adopting a balanced and healthy diet, under the supervision of healthcare professionals, can be an effective tool in improving symptoms associated with intestinal dysbiosis in women.

Potentially malignant lesions can be defined as areas whose tissue is morphologically altered and where cancer, in that location, is more likely to occur. These lesions can be triggered by environmental and behavioral factors, and, in this sense, this study seeks a relationship between electronic cigarettes and potentially malignant oral lesions. The objective of this work is to present a relationship between electronic cigarettes and potentially malignant oral lesions. The search for scientific articles to compose the research sample took place in June and July 2023, using the Medline and Web of Science databases, with an advanced search feature, using the following descriptors: "Oral neoplasm"; "Oral cancer" and "Electronic cigarette". It was found that all articles analyzed in this study showed some relationship between electronic cigarettes and potentially malignant lesions in the oral cavity. It is possible to identify relationships between electronic cigarettes and potentially malignant lesions in the oral cavity. However, studies are still scarce. In this sense, there is an indisputable need for more studies that seek to delve deeper into this topic, as it is extremely relevant to health. Although the evidence is still developing and there are significant gaps in research, the studies analyzed in this review indicate that electronic cigarettes may pose a risk for the development of potentially malignant lesions in the oral cavity. Importantly, more research is needed to fully understand the relationship between e-cigarette use and potentially malignant lesions in the oral cavity.

В данной статье предлагается решение для анализа и оптимизации данных с использованием самоорганизующейся

карты Кохонена. Разработан модифицированный алгоритм для формирования и дальнейшего преобразования карты на основе цветовых коэффициентов, соотнесенных с исходными данными. Предлагаемое решение отличается высокой наглядностью представления как исходных данных, так и полученных после преобразования результатов, а также простотой последующей интерпретации. Алгоритм, реализованный на языке программирования Python, предусматривает использование

данных без предварительной обработки, данных обработанных и приведенных в формат цветовых коэффициентов от 0 до 255 (формат Red Green Blue), шестнадцатеричный формат (HEX), а также данных, преобразованных в цветовые коэффициенты, используемые библиотекой Matplotlib. Рассмотрено применение нейронной сети для анализа входных данных в формате одномерного массива с двумя фиксированными цветовыми коэффициентами и трех одномерных массивов, где каждый массив исходных данных сопоставляется с одним из трех цветовых коэффициентов. Предложенный метод рассматривается в отношении данных Федеральной службы государственной статистики, а именно: Рентабельность продаваемых товаров, продукции (работ, услуг) организаций по добыче полезных ископаемых, обрабатывающих производств, по обеспечению электрической энергией, газом и паром; кондиционированию воздуха в 2021 году по данным бухгалтерской отчетности с использованием Государственного информационного ресурса бухгалтерской отчетности ФСН России. Полученные результаты могут стать основой для дальнейших исследований в области анализа данных и принятия решений на распределение ресурсов субъектов РФ и последующего прогнозирования уровня развития регионов во времени.

В статье рассмотрено возможность оценки жесткостных характеристик зданий по результатам экспериментальных измерений частоты их собственных колебаний. Определены периоды собственных колебаний здания с использованием эмпирических формул и стандартов некоторых стран мира. Проведено сравнение результатов вычислений и численного моделирования для оценки достоверности значений эмпирических формул. Проведены экспериментальные измерения динамических параметров здания методом случайного колебания и произведена первичная оценка жесткостных свойств материала. Результаты еще раз проверены экспериментом по определению жесткостных характеристик материалов строительных конструкций методом с использованием изгибных волн. Использование комбинации двух экспериментальных методов (метод случайного колебания и метод с использованием изгибных волн) необходимо для получения надежныхи высокоточных оценок об уровне повреждения здания при обследовании для реконструкции.

Проведен анализ положений нормативно-правовых актов, регулирующих проведение оценки технического состояния объектов строительства на различных стадиях жизненного цикла. Установлены особенности определения состава и объемов работ при проведении технического обследования, указываемых в программе работ. Предложен подход к формированию программы работ и, как следствие, установлению стоимости и сроков выполнения, основанный на результатах определения напряженнодеформированного состояния строительных конструкций и объекта в целом. Расчетное обоснование выполняется в рамках анализа результатов расчета пространственной модели «сооружение-основание», создаваемой на основании проектной документации и результатов визуального обследования. Особенно актуальным это становится при определении объемов детального обследования, связанного с использованием специального оборудования, лабораторной базы и пр.

Поднимается проблема выбора цветовых решений архитектурных объектов в городской среде. Проблема выбора цветовых решений фасадов зданий в городской среде связана с необходимостью создания гармоничного и эстетически приятного визуального облика города. При выборе цветовых решений для фасадов зданий необходимо учитывать множество факторов. Проведен подробный анализ научной литературы, который показал необходимость в проработке данной темы. Одной из проблем отсутствие универсальной методики формирования цветовых решений городской среды. Авторами рассмотрены существующие методы, разработанные отечественными учеными. В разработанных методах присутствуют общие принципы определения колористических решений для фасадов зданий, такие как: исторически сложившаяся архитектура, гармоничное сочетание цветовых решений, создание благоприятной композиции. Однако, данные методы не учитывают влияние колористики на психоэмоциональное состояние жителей, что на данный момент является очень важным. По этой причине, авторами ставится задача разработки универсальной методики, позволяющей учитывать этот фактор, охватывать все аспекты формирования целостной колористической среды, а также гибко подходить к основным критериям оценки экстерьеров градостроительных территорий и учитывать факторы, являющиеся предпочтительными для конкретных субъектов.

This article focuses on analyzing mobile phone reviews on JD.com as coding objects, effectively employing machine learning algorithms such as Latent Semantic Indexing (LSI), Latent Dirichlet Allocation (LDA), and text clustering in natural language processing to extract thematic keywords from online shopping review texts and perform axial coding. Subsequently, DBSCAN clustering algorithm is applied to categorize the main categories of design, service, and production under the perspective of businesses and consumers as consumption attraction, while categorizing price and brand under consumption intention, forming selective coding. By applying Grounded Theory to the analysis of online shopping reviews, this study accurately identifies consumer needs and feedback, with the aim of helping businesses improve product and service quality, enhance customer satisfaction and loyalty, and engage in personalized marketing and customized services.
Firefly Optimization-Based Buffer Replacement Algorithm to Improve Nand Flash Memory Performance
Authors: P. K. Singh Shweta,
Published: April 2024

Because of its shock tolerance, nonvolatility, low power consumption, and fast I/O speed, flash memory is often used for storage in consumer applications and, more recently, in the business computer environment. State drives SSDs to have not-in-place updates and asymmetric I/O latency, with write/erase operations being substantially slower than read operations. In this paper, we propose a buffer replacement technique FBRA that uses the firefly algorithm (FA) to precisely predict whether the pages residing in the buffer is hot or cold. The firefly optimization estimates hot fitness value of each page in the buffer in order to accurately classify them as hot or cold by characterizing precisely the temporal and spatial locality. To increase the hit ratio and SSD buffer use, the frequently used pages should stay longer in buffer compared to other pages. The proposed approach outperforms the existing SSD buffer management strategies regarding buffer hit ratio, write count, and runtime. Trace-driven simulation is done using FlashDB Simulator to support the performance of our approach surpasses various traditional buffer replacement policies.
Comparative Analysis of Early Diabetic Retinopathy Detection: Enhanced Minimal CNN vs VGG Architecture on CLAHE- Preprocessed Retinal Images
Authors: P. Ranjana Ebin P. M.,
Published: April 2024

Ocular impairment is one of the prominent problems affecting middle-aged individuals due to uncontrolled blood sugar levels, commonly known as Diabetic Retinopathy (DR). The small abnormalities in the retinal capillaries, called microaneurysms and intra retinal bleeding, are the initial symptoms of Diabetic Retinopathy. Clinically recognizing diabetic retinal disease is a time-consuming and difficult process due to limitations in resources and experienced doctors. Early detection is crucial in avoiding the progression of Diabetic Retinopathy, highlighting the importance of an automated DR detection method to identify symptoms in its early stages. In this paper, researchers developed an unfamiliar framework known as Enhanced Minimal Convolutional Neural Network (EMCNN) to classify Mild-DR and No-DR ophthalmic photos using a binary classification process. The proposed new model EMCNN is compared with the migration learning method using the existing framework VGG16 and VGG19 in terms of precision and effectiveness. Before being sent across the network, the fundus pictures underwent preprocessing using the Contrast Limited Adaptive Histogram Equalization (CLAHE) tactic. EMCNN is an experimental model that enjoys a minimum number of layers and batch normalization to minimize the training effort. The EMCNN model achieved 94.89% accuracy using 3100 image dataset which is a remarkable improvement when compared with VGG architectures since the VGG architecture is trained with millions of images.
