Antibody proteomics
Authors: Kazieva L.Sh. , Farafonova T.E. , Zgoda V.G.
Published: February 2023

Antibodies represent an essential component of humoral immunity; therefore their study is important for molecular biology and medicine. The unique property of antibodies to specifically recognize and bind a certain molecular target (an antigen) determines their widespread application in treatment and diagnostics of diseases, as well as in laboratory and biotechnological practices. High specificity and affinity of antibodies is determined by the presence of primary structure variable regions, which are not encoded in the human genome and are unique for each antibody-producing B cell clone. Hence, there is little or no information about amino acid sequences of the variable regions in the databases. This differs identification of antibody primary structure from most of the proteomic studies because it requires either B cell genome sequencing or de novo amino acid sequencing of the antibody. The present review demonstrates some examples of proteomic and proteogenomic approaches and the methodological arsenal that proteomics can offer for studying antibodies, in particular, for identification of primary structure, evaluation of posttranslational modifications and application of bioinformatics tools for their decoding.
Exergy-based sustainability analysis of biogas upgrading using a hybrid solvent (imidazolium-based ionic liquid and aqueous monodiethanolamine)
Authors: Kazmi Bilal , Ali Syed Imran , Awan Zahoor Ul Hussain
Published: February 2023

Energy may be generated in large quantities from fossil fuels, but this comes with environmental concerns. Thus, renewable resources like biogas, comprising carbon dioxide and methane, should be used alone or in combination with fossil fuels to mitigate the environmental footprints of energy generation systems. In this study, a new concept of hybrid solvent was presented, which combines 1-octyl-3-methylimidazolium tetrafluoroborate with aqueous mono diethanolamine for biogas upgrading process to provide high purity (≥ 99 wt%) and recovery (≥ 99 wt%) of biomethane. The process was simulated in ASPEN Plus® V.11. The thermodynamic framework was validated against experimental data, and rigorous regression was conducted to obtain binary parameters. To establish the efficacy of the suggested hybrid solvent, three scenarios were studied by altering the concentration of ionic liquid (5–20 wt%) linked with amine and compared to aqueous mono diethanolamine as the base case (50 wt%). The results showed that a hybrid solvent with 5 wt% 1-octyl-3-methylimidazolium tetrafluoroborate could increase CH4 purity to 99% (mol%). The hybrid solvent led to an energy saving of 64.94% compared to the amine-based system. Thermodynamic irreversibilities showed that 5 wt% 1-octyl-3-methylimidazolium tetrafluoroborate improved exergy efficiency by 54% over the amine-based procedure. Environmentally, the hybrid solvent system also achieved a higher capture rate (99%) and lower emissions (0.017 kW/kmol). Comparing the economic prospects, 5 wt% 1-octyl-3-methylimidazolium tetrafluoroborate saved 56% on total capital cost, making it competitive from an investment perspective.

Published: February 2023

Thermochemical treatment is a promising technique for biomass disposal and valorization. Recently, machine learning (ML) has been extensively used to predict yields, compositions, and properties of biochar, bio-oil, syngas, and aqueous phases produced by the thermochemical treatment of biomass. ML demonstrates great potential to aid the development of thermochemical processes. The present review aims to 1) introduce the ML schemes and strategies as well as descriptors of the input and output features in thermochemical processes; 2) summarize and compare the up-to-date research in both ML-aided wet (hydrothermal carbonization/liquefaction/gasification) and dry (torrefaction/pyrolysis/gasification) thermochemical treatment of biomass (i.e., predicting the yields, compositions, and properties of oil/char/gas/aqueous phases as well as thermal conversion behavior or kinetics); and 3) identify the gaps and provide guidance for future studies concerning how to improve predictive performance, increase generalizability, aid mechanistic and application studies, and effectively share data and models in the community. The development of biomass thermochemical treatment processes is envisaged to be greatly accelerated by ML in the near future.
Experimental Study of Rubber Composite Quality Assessment in Terms of Electrical Conductivity and Accelerated Thermal Ageing
Authors: Marasová, Jr. Daniela , Ambriško Ľubomír
Published: February 2023

Belt conveyors represent efficient transport systems that are used for transportation of bulk materials across all industries. Their basic structural component is a conveyor belt. During storage and deployment, conveyor belts undergo an inevitable process of ageing which leads to deterioration of their properties. A challenge associated with the use of conveyor belts is to ensure the required electrical conductivity. This challenge has prompted the research into conveyor belts that was aimed at identifying their electrical conductivity, considering primarily the effects of ageing. Identification of electrical conductivity of newly manufactured conveyor belts is important for manufacturers in order to comply with relevant standards, and for conveyor belt users in order to eliminate potential hazards.

Authors: Barsalou Matthew
Published: February 2023

This paper describes a subset of Industry 4.0, namely, Quality 4.0. Industry 4.0, has brought with it many changes to industry and changes that will directly impact root cause analysis. Massive amounts of data are being generated by industry 4.0 and previous quality tools and methods are no longer up to the task of handling such large amounts of data. Old root cause analysis tools and methods can still be used in Quality 4.0, but they must undergo adaptation to remain usable and high-quality professionals will need to update their skills.

Authors: Khoobdel Mehdi , Azari-Hamidian Shahyad , Hanafi-Bojd Ahmad Ali , Bakhshi Hasan , Jafari Amirsajad , Moradi Mohammad
Published: February 2023

Background: Scabies is referred to the infestation of skin by an ectoparasite, Sarcoptes scabiei. Having considerable financial consequences, this disease is a public health concern in several countries. In this review, we aimed to deter­mine the current status of scabies in different provinces of Iran.
Methods: Google Scholar, PubMed, Scopus, Science Direct, Scientific Information Database (SID), Sci-explore, Civil­ica, Magiran, Iranian Research Institute for Information Science and Technology and Elmnet databases were searched to find the related data in the time period within 2000–2022. To have a better insight into the status of prevalence of sca­bies in Iran, a meta-analysis and meta-regression was performed.
Results: A total of 943 relevant studies were retrieved from the databases, and 62 eligible studies met all the needed criteria for inclusion in this systematic review. Scabies was investigated and reported in at least 22 and 21 provinces of Iran respectively. Most of the studies were conducted in Tehran, Razavi Khorasan, Hormozgan, Fars and Guilan Prov­inces. Positive samples of scabies belonged to humans, sheep, goats, dogs, rabbits, mice and gazelles. Meta-analysis showed that the overall estimated presence of scabies in Iran during 2000–2022 was 7% (95% CI 4.7–10.3%, P< 0.001).
Conclusion: Infestations due to S. scabiei in Iran occur in different geographical locations and different climates. As a neglected tropical disease, the literature about the burden of scabies in Iran is inadequate. The present review highlights the importance of development of comprehensive strategies for the diagnosis and control of scabies, especial­ly the provinces with high infestation rates.

Published: February 2023

Background: The painful bite of Pulex irritans; causes wound on the host body and is a vector for Bartonella bacteria species, which can cause trench fever, Rickettsia species, Rocky Mountain spotted fever and Mediterranean spotted fe­ver. We conducted a study to find out the hosts, abundance, as well as the molecular characteristics of this flea species in Meshkin-Shahr County, Ardabil Province, northwest of Iran.
Methods: After collecting fleas from different reservoir hosts and transferring them to the laboratory, identification was done using different morphological characters as well as the internal transcribed spacer1 (ITS1) molecular marker.
Results: This morphological study indicated that from the 1053 fleas, which were collected from 162 different animals, including cats and dogs, 74 specimens belonged to human flea, Pulex irritans. In addition, in molecular analysis showed a high sequence similarity (99.5%) with the P. irritans counterparts from Spain country and Zanjan of Iran available in GenBank.
Conclusion: Pulex irritans species is an obligatory hematophagous ectoparasite of human and animals. Therefore, con­sidering the relatively high frequency of this species on the body of cats and dogs, it is suggested to conduct more stud­ies on its distribution and the possibility of being a vector of pathogens among these animals and human. The results of these studies will be used to compile and review the control programs of this vector.

Background: Ticks are blood-sucking ectoparasites of many vertebrates and act as vectors of a wide range of vector-borne diseases. Alongside pathogens transmission, ticks also cause economic losses in animal industry such as produc­tion loss, physical damage, anemia, and poisoning. This study aimed to determine the fauna, geographical distribution and seasonal activity of ticks collected from animals in Lorestan Province, west of Iran.
Methods: Ticks were collected from domestic animals including cattle, sheep, goats, chickens, turkeys, pigeons, as well as wild animals such as jackals in 2017–2018. Then, they were identified based on morphological characteristics using valid identification keys.
Results: Out of a total of 706 ticks, 433 (61.33%), 104 (14.73%), 33 (4.67%) and 136 (19.26%) ticks were collected in spring, summer, autumn and winter, respectively. In terms of hard ticks, 4 genera and 6 species were identified: Hy­alomma asiaticum (22.80%), Hyalomma anatolicum (3.68%), Hyalomma marginatum (2.40%), Rhipicephalus san­guineus (0.84%), Dermacentor marginatus (1.13%), and Haemaphysalis sulcata (0.64%). Additionally, two genera and four species fell into soft ticks: Argas persicus (60.48%), Argas reflexus (6.65%), Ornithodoros canstrini (0.70%) and Ornithodoros erraticus (0.42%). There was significant variation in the seasonal activity and abundance of ticks in dif­ferent seasons but in the tick abundancy among different regions.
Conclusions: The present study provides a perspective of the distribution status of ticks in Lorestan Province, their sea­sonal activity and the likelihood of emergence of related diseases.

The proposed Employee Management System is a web application that uses MYSQL Server as its database and acts as a bridge between users and the database, which houses all of the data. Its purpose is to enable the administrator to collect and save personnel information and records. The application also performs the leave management system task, which keeps track of all of the organization's employees' leave, allows for easy retrieval of information without the need for human intervention, and allows managers to manage their employees' leave and mark their leave dates. Furthermore, it will abolish the paper/file system, which will solve the current system's problems. Finally, it is revealed that this system would not only automate the entire procedure, but it will also save time for the administrator, which can be put to better use for his institute.
Shifting roles of Women through the Lens of Indian Popular Media
Authors: Padhi Prasanta Kumar , Nayak Anwesha , Singh Bidya
Published: February 2023

The importance of mass media has increased as a result of the development of new communication technologies. By portraying only a portion of truth and via the constant repetition of the same visual and audio, the mass media affects our ideas of social reality. Although the form and content of the media have evolved significantly over the past years, the media has always supported the stereotypical perceptions of women and their social responsibilities. The news about women's struggles and the injustices committed against them has always cast a shadow over them and their social contributions. In a changing world, it is essential that the print and electronic media paint a fair picture of women's multifaceted lives and contributions to society. This study aims to provide a picture of how women are perceived in the popular media, primarily the Bollywood movies and soap operas based on an analysis of the shifting stereotypes in the media's projection of women. It contends that women and their issues are no longer marginalised in the media. However, outdated sex stereotypes have persisted in various forms. Women have become more and more of a commodity in the media as a result of its rising commercialization. The mainstream media, on the other hand, frequently co-opts and re-constructs progressive rhetoric on women's concerns in order to establish the hegemony of dominant socioeconomic classes. As a result, in the setting of a capitalist economy, it is much harder to change how women are represented in the popular media.

Trombocitopenia por agregados plaquetarios: reporte de caso
Authors: Reibán Espinoza Esteban Adrián , Sanmartín Calle Yesenia Alexandra , Reibán Sanmartín Esteban Alexander
Published: February 2023

RESUMEN

Introducción: la pseudotrombocitopenia inducida por EDTA (ácido etilendiamino tetraacético) es un fenómeno de aglutinación de plaquetas que se presenta in vitro, mediado por anticuerpos anti-plaquetarios de tipo IgG, IgA o IgM dirigidos contra el complejo glucoproteínico IIb/IIIa de la membrana plaquetaria.

Caso clínico: presentamos un caso clínico de una paciente de 59 años de edad sometida a recambio valvular aórtico; clínicamente con evolución favorable durante el periodo posquirúrgico, sin embargo, en estudios de control se registra trombocitopenia severa, lo que llevo a cuestionar el uso de anticoagulantes y la necesidad de transfusión de plaquetas. Al realizar estudios complementarios se encontró agregados plaquetarios en el frotis de sangre periférica, posteriormente se realizó recuento seriado de plaquetas y comparación del histograma plaquetario, catalogando el caso como pseudotrombocitopenia.

Conclusión:

La trombocitopenia por agregados plaquetarios es una condición de baja incidencia (0.07% a 0.1%). Se debe a la agregación de plaquetas in vitro asociada al uso de anticoagulantes, frecuentemente etilendiaminotetraacético (EDTA), en el presente caso también se asoció al uso de citrato de sodio. Este problema no se asocia a sangrado, sin embargo su desconocimiento pudo haber llevado a realizar procedimientos diagnósticos y terapéuticos innecesarios.

Authors: Farias Andre Luis Assunção de , Malato Aline Pantoja
Published: February 2023

Os conflitos socioambientais produzidos por grandes projetos na Amazônia envolvem diferentes atores, como grandes empreendimentos rodoviários, hidrelétricos, portuários, minero-metalúrgicos e urbanos, gerando danos ambientais e colocando grupos sociais em colisão. Diante disso, o objetivo deste artigo é analisar os conflitos socioambientais produzidos pelos Grandes Projetos Urbanos (GPU) no Território Metropolitano de Belém (TMB), compreendendo como se manifestam na comunidade local. A metodologia, de base bibliográfica e de abordagem qualitativa, utilizou a abordagem da Ecologia Política, e o conceito de conflito socioambiental. Conclui-se que os conflitos socioambientais originados de GPUs, a exemplo do Aterro Sanitário de Marituba; do BRT Belém e da Macrodrenagem da Estrada Nova, indicam uma disputa assimétrica tanto do ponto de vista econômico quanto cultural e político entre os grupos sociais envolvidos, contribuindo para a reprodução da desigualdade ambiental na Amazônia e, por conseguinte, para a criação e perpetuação de riscos e danos desproporcionais sobre os mais pobres e moradores da periferia do TMB.

Authors: Heiser Rebecca , Dello Stritto Mary Ellen , Brown Allen , Croft Benjamin
Published: February 2023

When higher education institutions (HEIs) have the potential to collect large amounts of learner data, it is important to consider the spectrum of stakeholders involved with and impacted by the use of learning analytics. This qualitative research study aims to understand the degree of concern with issues of bias and equity in the uses of learner data as perceived by students, diversity and inclusion leaders, and senior administrative leaders in HEIs. An interview study was designed to investigate stakeholder voices that generate, collect, and utilize learning analytics from eight HEIs in the United States. A phased inductive coding analysis revealed similarities and differences in the three stakeholder groups regarding concerns about bias and equity in the uses of learner data. The study findings suggest that stakeholders have varying degrees of data literacy, thus creating conditions of inequality and bias in learning data. By centring the values of these critical stakeholder groups and acknowledging that intersections and hierarchies of power are critical to authentic inclusion, this study provides additional insight into proactive measures that institutions could take to improve equity, transparency, and accountability in their responsible learning analytics efforts.

Published: February 2023

Abstract

Introduction: Recently cesarean section rate has increased significantly all over the world. The information provided by the healthcare provider during pregnancy follow-up is important for the pregnant women to decide on the delivery method. In particular, information about normal birth; may help reduce rising cesarean rates by curbing fears of obscurity and widespread public rhetoric. The aim of this study is to investigate the effect of the education given by the prenatal school on the delivery method preferred by the pregnant women.

Methods: This descriptive study includes equal number of nulliparous pregnant women who applied to Ankara Training and Research Hospital Gynecology and Obstetrics outpatient clinic, who attended or did not attend the prenatal school between January 2020 and November 2022. The effect of education on decision making was investigated by comparing delivery methods according to the status of being educated in the pregnancy school and the primary cesarean section rate of the same number of nulliparous pregnant selected from among the uneducated pregnant women who gave birth in the same period in our clinic were compared.

Results: In our study, 44 (81.5%) of the 54 nulliparous pregnant women who received education gave normal birth, while 33 (61.1%) of 54 those who did not receive education gave birth normally. A statistically significant difference was found between the two groups in terms of delivery mode (p

Солошенко // Известия Томского политехнического университета. Инжиниринг георесурсов. – 2023. – Т. 334. – № 2. – С. 7-21.

Актуальность исследования обусловлена необходимостью познания фундаментальной научной проблемы – железомарганцевый рудогенез Мирового океана. Помимо перспективного минерального сырья морские железомарганцевые образования являются регистраторами условий седиментации в прошлом. Их формирование осуществляется при различных процессах, которые отражены в вещественном и изотопном составе. В настоящее время наименее изученным регионом Тихого океана является его северный сегмент. Цель: изучить изотопный состав Sr и Nd железомарганцевых корок северной Пацифики, формирующихся в условиях низкого терригенного потока. Методы: литолого-морфогенетический; рентгеноструктурный – определение минерального состава; масс- спектрометрический – определение химического и изотопного состава. Результаты. Исследованы железомарганцевые образования гайотов северной части Императорского хребта (Детройт, Сьюзей, Ханзей) и разломных зон Амлия, Рат и Стейдмейт, а также гайота Вулканолог (Магеллановы горы) в качестве сравнительного материала. На основании текстурно-структурных и минералого-геохимических особенностей изученные железомарганцевые образования отнесены к гидрогенным железомарганцевым коркам. Изотопный состав стронция изученных образцов находится в интервале от 0,70797 до 0,70919 (среднее 0,70885). При этом содержание стронция изменяется почти в три раза – от 660 до 1700 г/т. Зависимости изотопного состава от концентрации Sr не отмечается. Смещение величины отношения 87Sr/86Sr происходит к его значениям, характерным для вулканических пород, что является отражением высокого количества кварц-плагиоклазовой примеси в образце. Изотопный состав неодима в пересчете на εNd варьирует в интервале от –3,5 до –3,0, что соответствует современному значению глубинной воды северной Пацифики. Повышение значение εNd до –2,3 соответствует пробе с максимальной аллотигенной примесью. Минимальное значение величины εNd (–4,4) установлено в подошвенном слое железомарганцевой корки гайота Ханзей. Такое значение соответствует миоценовой глубинной воде северной Пацифики. Это является основанием полагать, что в миоцене на формирование вещественного состава железомарганцевых корок северной Пацифики оказывали влияние глубинные атлантические воды, поступающие через Панамский пролив. Прекращение их поставки в Тихий океан произошло, вероятно, пять млн лет назад.

Чаркин, Е.И. Ярощук, О.В. Дударев, Н.А. Смирнова, Н.В. Гусева, И.П. Семилетов // Известия Томского политехнического университета. Инжиниринг георесурсов. – 2023. – Т. 334. – № 2. – С. 130-146.

Актуальность исследования определяется необходимостью оценки региональных особенностей транспорта и преобразования органического вещества в различных седиментационных и биогеохимических обстановках, действующих на Восточно-Сибирском арктическом шельфе, в том числе в Восточно-Сибирском море – наиболее ледовитом и наименее изученном море Российской Арктики. Цель исследования заключается в определении состава и источников органического вещества донных осадков Чаунской губы (Восточно-Сибирское море). Объекты: 25 проб поверхностных донных осадков, отобранных по профилю от прибрежной зоны Чаунской губы до внутренней части шельфа Восточно-Сибирского моря в ходе комплексной научно-исследовательской морской экспедиции на борту НИС «Академик Опарин» в сентябре–октябре 2020 г. Методы. Для анализа групп углеводородных соединений ОВ донных осадков был применен пиролитический анализ по методу Rock-Eval; оценка распределения н-алканов проводилась на основе результатов газовой хромато-масс-спектрометрии. Гранулометрический анализ осадков выполнялся на лазерном анализаторе частиц. Результаты. Состав осадочного материала в Чаунской губе преимущественно определяется особенностями подводного рельефа и гравитационными потоками поступающего терригенного материала – продуктов локальной термоабразии береговой зоны (о. Айон) и речного аллювия в юго-восточной части губы. Определенную роль в формировании седиментационного облика губы, предположительно, играют процессы вытаивания криозоля в результате разрушения областей припайного льда. Данные пиролиза и анализ распределения н-алканов для поверхностных осадков указывают на смешанный генезис органического вещества в поверхностных осадках с доминирующим вкладом наземного органического вещества высокой степени преобразованности и высокое содержание трудноразлагаемых гуминовых веществ и фульвокислот. Присутствие автохтонного органического вещества отражает высокую продуктивность вод Чаунской губы.

Background: This study assessed the effect of different sticking agents viz., gum arabic, guar gum and xanthan gum for coating Rhizobium sp. and Arbuscular Mycorrhizal Fungi (AMF) on seed germination and vigour of blackgram seeds. Methods: The surface sterilised seeds were first coated with different sticking agents as per the following treatments, T0 - Dry seed, T1 - Water, T2 - Gum arabic 20% w/v, T3 - Guar gum 0.5% w/v, T4 - Xanthan gum 0.3% w/v followed by coating with Rhizobium sp. and AMF liquid cultures. Result: Among the different sticking agents, gum arabic (20%) when used as a sticker for coating Rhizobium sp. and AMF, increased the seed germination (95%) and vigour index (21.85) of blackgram compared to the control. The efficacy of inoculation depended on the survival of inoculants on seeds. On using sticking agents, the survival of microbes could be extended up to 48 h of treatment and 87 per cent AMF colonization with gum arabic (20%) as deduced from the viability studies.

Quo vadis Transylvania?: Hungarian and Romanian resolution for Transylvania during World War II
Authors:   East European and Balkan Institute, Kim Jiyoung
Published: February 2023

World War I and World War II were the most important inflection points in Hungarian history. As a result of World War I, historical Hungary was annihilated with the dissolution of the Austro-Hungarian Monarchy. In particular, as Transylvania, the cause of the conflict between Hungary and Romania, belonged to Romania, Hungary and Romania have maintained uncomfortable relations until now. The defeat of Germany's alliance with Hungary in World War II brought territorial gains to Romania's alliance with the Soviet Union. In this article, we looked at the various measures and discussions that Hungary and Romania had during and after World War II regarding the Transylvania issue. In the end, the interests of the great powers were the decisive factor that separated the fate of the two countries.
Economic Contribution of the Financial Sector to the Russian Economy with I-O Analysis

Published: February 2023

After the outbreak of the Russia-Ukraine War in February 2022, Russia was effectively cut off from the global financial system by being kicked out of the SWIFT payment network. Consequently, the development of the financial market has become an urgent task for Russia. In this paper, an inter-industry analysis was conducted for countries in transition, such as Russia, the Czech Republic, 경Poland, and Kazakhstan, using input-output tables from 1999 to 2018 provided by the OECD. According to the research findings, the financial industries of the four countries showed relatively high forward linkage effects and low backward linkage effects. In other words, they are categorized as intermediate-demand primitive industries. In addition, the Russian financial industry was found to have the following characteristics. First, it does not yet account for a large portion of the national economy and has experienced ups and downs due to economic fluctuations, but is growing relatively steadily. Second, although the financial industry is not a core industry in the Russian economy, it is of great importance because of its relatively high-added value and production support effect of other industries. Third, given the growing support effect of other industries, it is likely that the higher productivity and efficiency in the financial market will contribute to the competitiveness of other industries. This suggests the need to increase the proportion of the Russian financial industry in the national economy. In this context, the policy for the efficient development of the financial market implemented by the Russian government appears to be desirable. In particular, if the efficiency of the financial sector is improved and costs are reduced through the development of fintech, it will contribute more to the growth of other industries and the national economy.

Os aplicativos e a internet têm auxiliado na superação de problemas de espaço e tempo. Por meio de computadores e smartphones temos acesso a inúmeros bens e serviços sem sair de casa, o que poupa tempo, gastos com transporte entre outras situações desgastantes como esperas em filas e congestionamentos. Concomitantemente, tanto a estrutura física, quanto o mercado de trabalho têm se transformado com o avançar da tecnologia. Os bancos são um exemplo de organizações que estão migrando para plataformas digitais, deixando de lado os espaços físicos e dispensando parte da mão-de-obra. Por outro lado, as cooperativas crédito estão abrindo novas agências e contratando trabalhadores, numa clara estratégia oposta aos concorrentes. Esse é o objeto de análise desse trabalho, que investiga a dinâmica de empregos formais entre as cooperativas de crédito entre 2006 e 2018.

Performance of a 7-Type HPV mRNA Test in Triage of HPV DNA Primary Screen Positive Women Compared to Liquid-Based Cytology
Authors: Sørbye Sveinung Wergeland , Falang Bente Marie , Antonsen Mona
Published: February 2023

Background: A plethora of data supports HPV-based screening to be the preferred strategy for cervical cancer prevention. The shift to a more sensitive firstline test brings the need of effective triage up for discussion. Currently, most algorithms apply cytology as triage of HPV-DNA positive women. This study compared the performance of a 7-type HPV-mRNA test to cytology. Methods: From 2019-01-01, until 2021-12-31, cervical samples from 58,029 women were examined at the University Hospital of North Norway. 30.5% (17,684/58,029) fulfilled the criteria for HPV-DNA primary screening. All positive samples were triaged by cytology and followed-up according to national guidelines through 2022. Additionally, a 7-type HPV-mRNA test was applied. Study endpoint was histologically confirmed high grade lesion (CIN2+). Results: 5.6% (990/17,684) had positive HPV-DNA test, 97.2% (962/990) with valid HPV-mRNA results. 55.5% (534/962) had abnormal cytology (ASC-US+) and 35.1% (338/962) had positive HPV-mRNA test. 13.9% (134/962) had CIN2+. Sensitivity (CIN2+) of cytology versus the HPV-mRNA test was 76.1% (102/134)) versus 73.1% (98/134)), p=0.67. The specificity was 47.8% (396/828) versus 71.0% (588/624), p<0.001. PPV was 19.1% (102/534) and 29.0% (98/338), p<0.001 respectively. The number of colposcopies per CIN2+ detected by cytology and HPV-mRNA test was 5.2 and 3.1. Conclusion: The 7-type HPV mRNA test was significant more specific than cervical cytology in triage of HPV-DNA positive women. Using this biomarker as threshold for colposcopy may better balance the benefits and harms of screening.

Published: February 2023

The paper portrays predictive models for dissolved oxygen (DO) levels in an urban lake using common water quality parameters like Temperature, pH, Conductivity and ORP at a time. Data were sampled using three real-time, industry-standard sensors, OPTOD, CTZN, and PHEHT, and then interpolated using the ArcGIS kriging technique. Correlation studies were analyzed through the ML algorithm, the correlation study signified a highly positive correlation between DO and other water parameters and the model was corroborated by R-score in order to create the linear regression model. In addition, an artificial neural network- a machine learning method using the Levenberg-Marquardt algorithm was developed to build a model to predict the do as well. Then, the performance of the models was validated and also the R2 accuracy was checked of the predicted data against the actual data. Thus, the appropriateness of the ANN model for the forecasting of investigated attributes is indicated by the fact that the discrepancy between the forecasted and real ANN model is significantly lesser than that of the regression model. However, the model can be used to reveal DO data from unknown urban lake water.
SenGlove - A Modular Wearable Device To Measure Kinematic Parameters Of The Human Hand
Authors: David Jonas , Helbig Thomas , Witte Hartmut
Published: February 2023

For technical or medical applications, the knowledge of the exact kinematics of the human hand is key to utilizing its capability to handle and manipulate objects and to communicate with other humans or machines. The optimal relationship between the number of measurement parameters, measurement accuracy as well as complexity, usability and cost of the measuring systems is hard to find. Biomechanic assumptions, the concepts of a biomechatronic system and the mechatronic design process as well as commercially available components are used to develop a sensorized glove. The proposed wearable can measure 14 of 15 angular values of a simplified hand model introduced in this paper. Additionally, five contact pressure values at the fingertips and inertial data of the whole hand with a degree of freedom of six are gathered. Due to the modular design and a hand size examination based on anthropometric parameters, the concept of the wearable is applicable for a large variety of hand sizes and adaptable to different use cases. Validations show a combined root-mean-square error of 0.99° to 2.38° for the measurement of all joint angles at one finger, surpassing the human perception threshold and the current state of the art in science and technology for comparable systems.

Published: February 2023

In this paper, in order to provide proper parameters for the preparation of semi-solid billets, the semi-solid annealing of hot-rolled 2A14 Al alloy was investigated. The microstructure was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) with X-ray energy dispersive spectrometer (EDS) and electron backscattered diffraction (EBSD), scanning transmission electron microscope (STEM). XRD results show that with the increase of temperature, equilibrium θ-Al2Cu gradually dissolved in the matrix. The EDS results of SEM and STEM show that there were coarse θ-Al2Cu phase, ultra-fine precipitate Al(MnFeSi) or (Mn, Fe)Al6 phase and atomic clusters in the microstructure. EBSD results show that the recrystallization mechanism was dominated by continuous static recrystallization (CSRX), the homogeneous nucleation occurred when the sample was heated to near solidus temperature, and CSRX happened in the semi-solid temperature. In the process of recrystallization, the micro-texture changed from preferred orientation to random orientation. A variety of experimental results show that static recrystallization (SRX) occurred at semi-solid temperature due to the blocking effect of atomic clusters on dislocation slip and the Zener drag effect of fine precipitates on low angle grain boundaries (LAGBs) disappeared with melting at semi-solid temperature.
Optimization of Pile Driver Frame Based on Sensitivity Analysis
Authors: Wu JinMei , Yang Yanqing
Published: February 2023

The optimization of the pile driver frame is very important to the overall performance of the pile driver. This paper takes the large body structure of a model of hydraulic static pile driver as the research object. ANSYS APDL finite element software is used to perform static analysis and sensitivity analysis on the large body structure of the pile driver. On the premise of meeting the design requirements, according to the most dangerous working conditions of the pile driver, the size optimization of the frame structure of the pile driver is carried out based on sensitivity analysis. The mathematical model is established with the plate thickness as the design variable, the strength and stiffness of the body structure as the constraints, and the minimum mass of the body structure as the objective function. The optimization results show that the optimization design model based on sensitivity analysis not only meets the strength and stiffness conditions of the large structure, but also reduces the structural quality by 22.1% and greatly saves the production cost.
