Karya Murni is one of the areas in the northern arm of Sulawesi that has been tectonically influenced. Tectonic processes have implications for the formation of rocks and geological features that have the potential to be developed into geodiversity sites. The development of geological features as a geodiversity site in aspiring geopark Gorontalo can protect valuable geological features from frequent degradation. This research aims to analyze and conduct quantitative assessments of geological diversity in Karya Murni, Gorontalo. The research method used is field observation, laboratory analysis, and geodiversity assessment. Field observations included observing landform, collecting rock samples, and measuring geological structures. Field observations were also carried out to observe aspects of the geodiversity assessment which included science, education, tourism, and risk degradation. Laboratory analysis consists of geomorphological analysis, petrographic analysis, and geological structure data analysis. Geodiversity assessment uses the Geological Survey Center of Indonesia assessment. The results suggest that the geomorphology of the study area can be divided into four geomorphic units - the volcanic hills, denudational hills, Karst hills, and fluvial plain units. The stratigraphy of the research area is divided into four units from the age of the early Eocene to the Holocene - the andesite lava, volcanic breccia, reef limestone, and alluvial deposit units. The geological structure of the study area is a trending northeast–southwest to northwest–southeast. Active faults at the location of the study area consist of the Apitalawu normal fault. At recent states, generally geosites of the Karya Murni have moderate scientific values, the low educational and touristic values and high risk of degradation. The geodiversity potential of the research area can be utilized for further research and education.

Due to a significant increase in the number of spacecrafts in low orbit, the problem of planning observations by radio instruments acquires significant importance. The paper shows that this problem can be reduced to the problem of optimization of observation time. Two metrics for plan quality evaluation are proposed (minimum value metric and geometric mean metric). It was suggested 3 optimization algorithms for planning: maximization of arithmetic mean, minimization of quadratic deviation from mean, maximization of geometric mean. A comparison of the proposed algorithms and the adaptive random walk algorithm was carried out. As a result of experimental research, it has been found out that the best quality for the chosen metrics is the maximization algorithm of geometric mean. However, the time required for calculation of the schedule is more than 65 times more than for other algorithms.
Legislative Mechanisms of the European Union and of Transposition into the Romanian Legislation Concerning the Problem of Work-Life Balance for Parents and Caregivers - Sociological Aspects
Authors: Boghirnea Iulia
Published: June 2023

In this study, we want to analyse the legal framework of the European Union regarding family leaves and flexible work formulas, measures that the Member States must take by transposing the Directive 2019/1158 of the European Parliament and the Council of Europe on work-life balance for parents and caregivers. A novelty in the Union legislation is the fact that this Directive replaces the notion of “reconciliation” with that of “balance”, and the notion of “family life” with that of “private life of parents and caregivers”. Also, the Directive, which had to be transposed by all EU Member States by August 22, 2022, aims to promote and facilitate the reintegration of mothers into the labour market after the period of maternity leave and parental leave, but, in particular: fathers’ right to paternity leave, parental leave, caregiver’s leave and not least, flexible working arrangements for workers who are parents or caregivers. As for fathers’ right to paternity leave, the EU legislator provides that it can be requested around the child’s birth date, before or after birth and should be granted regardless of the marital or family status, as will be defined in the internal law of each state. The parental leave granted to fathers can be extended by one or two months, a period of time that cannot be transferred to the other parent. The right to this leave will be guaranteed, by law, to all workers who have parental responsibilities. Finally, we will analyse how Romania transposed this Directive into the internal legislation. Keywords: European Union, private life of parents and caregivers; Parental leave; Flexible working; Transposing the Directive (EU) 2019/1158 into the internal legislation
Análisis ambiental de la extracción y el uso de la arena del delta del Paraná
Authors: Zagel Mauro A.
Published: June 2023

El aporte del río Paraná permite el desarrollo de los servicios ecosistémicos que ofrece el delta del Paraná al área más poblada de Argentina. En la actualidad, uno de los principales servicios tiene que ver con la provisión de arena cuya extracción y uso sobre el tramo final del delta y en el corredor metropolitano se ha intensificado notablemente. A pesar de que aún no conoce escasez de arena, se prevé un agravamiento de la situación debido a las estimaciones de crecimiento del corredor metropolitano y de la producción de gas natural en Vaca Muerta. Más aún, se crea un escenario de retroalimentación donde la arena (y áridos) extraídos retornan en nuevas formas de presión, propias del avance metropolitano y agrario sobre los humedales y con ello, un aumento en el consumo de recursos naturales al que se asocia una mayor demanda de energía (gas natural, petróleo). Así pues, se aplicó una perspectiva de pensamiento sistémica y multiescalar (espacio temporal), un estudio holístico cualitativo basado en aplicar el modelo DPSIR (Factores Determinantes-Presión-Estado-Impacto-Respuesta), lo cual permitió el reconocimiento de causas y consecuencias que degradan los servicios ecosistémicos del delta del Paraná y el bienestar humano, además de ofrecer nuevas respuestas a los efectos causados por la extracción y el uso de las arenas fluviales y de los médanos de Ibicuy.

Published: June 2023

За даними досліджень установлено, що рівень вітаміну D пов’язаний з інсулінорезистентністю (ІР) та наявністю цукрового діабету (ЦД) 2 типу. Підтверджено значення вітаміну D у розвитку ІР та ЦД 2 типу в осіб із надмірною масою тіла та ожирінням. У попередніх дослідженнях виявлено високу частоту дефіциту та недостатності вітаміну D (25(OH) D) у хворих на ЦД 2 типу. Відсутня інформація про зв’язок між гіповітамінозом D і гіперлептинемією. Не встановлено, чи відрізняється ця асоціація в осіб з ІР та без неї.
Мета роботи — дослідити взаємозв’язок між (25(OH)D) і лептином в осіб з ІР та без неї.
Матеріали та методи. Під спостереженням перебували 76 осіб, яких розподілили на дві групи дослідження (по 38 пацієнтів у кожній групі). До першої групи залучили осіб з ІР (індекс HOMA IR >2,7), до другої — пацієнтів без ІР (індекс HOMA IR <2,7). Проведено порівняння вмісту 25(OH)D та лептину, антропометричних і біохімічних параметрів у групах та вивчено кореляційний зв’язок між 25(OH)D, лептином та індексом HOMA‑IR.
Результати. В осіб з ІР зафіксовано статистично значущо нижчий рівень 25(OH)D і статистично значущо більший вміст лептину порівняно з пацієнтами без ІР. У жінок концентрація 25(OH)D була статистично значущо нижчою, вміст лептину — статистично значущо більшим порівняно з показниками у чоловіків. Виявлено статистично значущий обернено пропорційний зв’язок між рівнями 25(OH)D у сироватці крові та лептину. У жінок на відміну від чоловіків цей зв’язок був статистично значущим (відповідно r=–0,4; p=0,04 і r=–0,042; p=0,8). Установлено сильний обернено пропорційний зв’язок між індексом HOMA IR та рівнем 25(OH)D лише в осіб з ІР, а також прямо пропорційний зв’язок між індексом HOMA‑IR та рівнем лептину в сироватці крові (r=+0,27; p=0,015).
Висновки. Виявлено вищий вміст циркулюючого лептину та нижчий рівень 25(OH)D в осіб з ІР. Концентрація 25(OH)D обернено пропорційно пов’язана з рівнем лептину, особливо у жінок.

Authors: Korolova Zh.V. , Vasilchuk Е.O.
Published: June 2023

Objective — to compare the effectiveness of combined ablative and non-ablative methods of laser treatment and cryodestruction in patients with widespread papillomatosis.
Materials and methods. For treatment we used the Fotona SP Spectro new laser system which has two handpieces — for ablative (wavelength 2940 nm, erbium laser) and non­ablative (neodymium Nd:YAG laser, wavelength 1064 nm) treatment methods, Fotona S11 scanner (neodymium laser, wavelength 1064 nm) and Cry­ac cryospray.Under observation were 45 patients with widespread recurrent papillomatosis, with confirmed papillomavirus infection (ICD10 code D23.5; ICD11 XH17Q9). The lesion area was the front surface of the chest, under the mammary glands, the area of the treatment area — 10 × 10 cm.According to the inclusion and exclusion criteria from the retrospective analysis of the disease histories, three groups of patients were formed: group 1 — treatment according to the accepted method of laser therapy with an erbium (ER:YAG) laser, group 2— combined ablative and non­ablative laser therapy (with erbium and neodymium lasers) and group 3 — cryodestruction of papillomas.
Results and discussion. The best result and the speed of the obtained positive results of the treatment and a significantly less frequent occurrence of new elements during the observation within a year after the start of therapy were shown by group 2 — where combined laser therapy was applied. Significant advantages of laser therapy over cryodestruction were determined according to the results of this study and according to the current literature.
Conclusions. The combined method of laser therapy, especially the mechanisms of the pathogenesis of the obtained therapeutic effect, require careful study. According to the obtained results, this approach is the most effective in terms of both aesthetic and therapeutic (positive effect on pathogenetic links) achievements.

Published: June 2023

Objective — to conduct a comprehensive retrospective study of the medico-social and epidemiological direction regarding the structure, determinants and cause-and-effect relationships between the performance of professional duties and skin diseases in sailors; substantiate proposals for additional measures that will improve the level of health protection of water transport workers of Ukraine to international standards.
Materials and methods. The research methods applied in the work were as follows: bibliosemantic, statistical observation, analytical and structural analysis. These methods made it possible to process only valid, complete and up-to-date information, to make correct and thorough conclusions about the nature and regularities of the researched process.
Results and discussion. The volume of water transportation of chemicals, goods or foods that were treated with chemicals is increasing every year. Some cargoes on board ships are disinfected, in particular, with the help of toxic fumigants. All fumigants that are used to protect transported goods are a potential health hazard for workers and can cause, among other things, occupational dermatoses.Available data on the study of sanitary-chemical, hygienic and epidemiological parameters of working conditions, living conditions and morbidity of dockers and sailors during transshipment in ports and transportation of bulk freight on ships of the bulk fleet indicate contamination of workplaces with dangerous and harmful substances, which caused damage to the mucous membranes and skin coverings.
Conclusions. The mechanisms of health preservation and emergency response readiness constitute a complex scientific and practical problem and require further thorough study, considering the variety of determinants and risk factors in water transport, the differences in their physical and chemical properties, as well as the potential impact on human health and the aquatic environment. Scientifically based proposals have been provided regarding additional measures, the implementation of which will bring the level of health protection of water transport workers of Ukraine closer to international standards. Among the scientific and practical tasks related to the treatment and prevention of skin diseases among water transport workers, the priority is given to the implementation of modern diagnostic algorithms, training of personnel, organization of telemedical consultations, updating the completeness of ship’s first-aid kits in order to provide timely, high-quality emergency medical care as needed.

Published: June 2023

Biochars made from brewer’s spent grain were added to the anaerobic digestion of brewer’s spent grain to enhance the methane fermentation process and improve biogas production. In research, the effect of biochars made at 300, 450, and 600 °C and doses of 1-8% added to anaerobic digestion was tested. The biochemical biogas potential tests in mesophilic conditions were performed. The tests took 28 days, the biogas yield for each reactor varied from 500-650 ml×gVS-1, and around 60% substrate degradation was obtained. For each test, the kinetics parameters using the first-order model were determined. The constant biogas production rate (k), and the biogas production rate (r) varied from 0.05-0.08 d−1, and 42-60 ml×(gVS×d)−1 respectively. Though the differences in biogas production turned out to be statistically insignificant (p<0.05) due to the high disappearance in obtained data and conflicting effects, the response surface area analysis showed that biochar made at 450 °C at the share of 1-4% could be used to maximize biogas production. Nevertheless, supplementation with biochar needs to be done carefully since in many cases, a reduction in biogas production was observed

Published: June 2023

Hydrogen is widely recognised to play a key role to decarbonise various industries, as well as transportation, heating and power sectors, for it does not generate greenhouse gas emissions at the point of use. Understanding the technologies that can generate low carbon hydrogen is essential in planning the development of future gas networks and more sustainable manufacturing processes. One promising approach is hydrogen production by gasification of waste, referred to as biohydrogen. This paper summarises work undertaken to design a commercial Waste-to-Hydrogen (WtH2) plant, which includes an assessment of current development stage of technologies, the identification of an appropriate scale for the plants, and development of specifications for process design and output streams. The overall production levels of biohydrogen is observed to be limited by the availability of sustainable feedstocks; however, the results of negative CO2 emissions achieved via biohydrogen production shows that its overall potential to reduce GHG emissions is significantly better, as compared to other form or low carbon hydrogen. In particular, biohydrogen application is capable of generating negative emissions that are required to offset GHGs from other sectors in the future. In combination, low carbon hydrogen production can make a very important contribution to achieving net zero commitment in UK.

Metastasis to the brain occurs in a significant fraction of patients with breast cancer and lung cancer (1-3). We mined published RNA-sequencing and multiplexed gene expression data (4, 5), comparing primary and brain metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the CNS. We found that toll-like receptor 10, encoded by TLR10, was among the genes whose expression was most different in the brain metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. Multiplexed gene expression data (5) revealed conserved differential expression of TLR10 in CNS metastasis in patients with lung cancer. TLR10 mRNA was present at decreased quantities in metastasis to the brain in humans with lung cancer. Expression of TLR10 in primary tumors of the breast was correlated with overall, distant metastasis-free and recurrence-free survival. Modulation of TLR10 expression may be relevant to the biology by which tumor cells metastasize from the breast to the brain in humans with cancer of the lung and breast.

BackgroundIn contrast to evidence for interventions supporting victim/survivors of domestic violence and abuse (DVA), the effectiveness of perpetrator programmes for reduction of abuse is uncertain. This study aims to estimate the effectiveness and cost-effectiveness of a perpetrator programme for men.MethodsPragmatic two-group individually randomised controlled trial (RCT) with embedded process and economic evaluation. Five centres in southwest England and South Wales aim to recruit 316 (reduced from original target of 366) male domestic abuse perpetrators. These will be randomised 2:1 to a community-based domestic abuse perpetrator programme (DAPP) or usual care comparator with 12-month follow-up. Female partners/ex-partners will be invited to join the study. The intervention for men comprises 23 weekly sessions of a group programme delivered in voluntary-sector domestic abuse services. The intervention for female partners/ex-partners is one-to-one support from a safety worker. Men allocated to usual care receive no intervention, however are free to access other services. Their partners/ex-partners will be signposted to support services. Data is collected at baseline, and 4, 8, and 12 months’ follow-up. The primary outcome is men’s self-reported abusive behaviour measured by the Abusive Behaviour Inventory (ABI-29) at 12-months. Secondary measures include physical and mental health status and resource use alongside the abuse measure ABI (ABI-R) for partners/ex-partners and criminal justice contact for men. A mixed methods process evaluation and qualitative study will explore mechanisms of effectiveness, judge fidelity to the intervention model using interviews and group observations. The economic evaluation, over a one-year time horizon from three perspectives (health and social care, public sector and society), will employ a cost-consequences framework reporting costs alongside economic outcomes (Quality Adjusted Life Years derived from EQ-5D-5L, SF-12 and CHU-9D, and ICECAP-A) as well as the primary and other secondary outcomes.DiscussionThis trial will provide evidence of the (cost)effectiveness of a DAPP. The embedded process evaluation will further insights in the experiences and contexts of participants and their journey through a perpetrator programme, and the study will seek to address the omission in other studies of economic evaluations.

Reinforcement Learning for Limited Labeled Classification
Authors: Chun Xaolin
Published: June 2023

This paper explores the application of reinforcement learning techniques in the context of limited labeled classification tasks. Limited labeled data scenarios, where the availability of labeled samples is scarce or expensive, pose significant challenges for traditional supervised learning methods. Leveraging the power of reinforcement learning, this study proposes a novel framework that addresses the issue of limited labeled data by combining active exploration and uncertainty-based strategies. The framework utilizes an agent that interacts with the environment, actively selecting instances to label based on uncertainty estimates and exploration-exploitation trade-offs. Reinforcement learning algorithms, such as Q-learning or policy gradient methods, are employed to train the agent to make informed decisions on the most informative instances to label. Experimental evaluations on various benchmark datasets demonstrate the effectiveness of the proposed approach, showcasing improved classification performance compared to traditional supervised learning methods in limited labeled scenarios. The findings of this study provide insights into the potential of reinforcement learning for addressing the challenges posed by limited labeled classification tasks, offering a promising avenue for practical applications in domains with limited labeled data availability.
Geochemical Insights: Unraveling the Influence on Kerogen and Organic-rich Mudrocks
Authors: Alaquib Mohammad
Published: June 2023

The examination of geochemical factors and their impact on kerogen and organic-rich mudrocks holds significant implications for reservoir characterization, hydrocarbon exploration, and production strategies. The understanding of the geochemical environment empowers reservoir engineers and geoscientists to gain valuable insights into the distribution, quality, and producibility of hydrocarbons trapped within these formations. This knowledge is particularly crucial in the efficient development of unconventional resources, including shale gas and tight oil, as their successful exploitation heavily relies on comprehending the behavior and properties of kerogen and organic-rich mudrocks.Therefore, geochemistry assumes a critical role in unraveling the properties and behavior of kerogen and organic-rich mudrocks, which are fundamental to petroleum geology and hydrocarbon exploration. This comprehensive review delves into the wide-ranging influence of geochemistry on various facets of kerogen and organic-rich mudrocks. Specifically, it investigates the interplay between geochemical factors and their effects on the physical properties of kerogen, wettability characteristics, adsorption properties, wettability of organic-rich mudrocks, and dynamic properties within kerogen pores. By examining the intricate relationship between geochemical processes and these organic-rich materials, this review sheds light on their behavior and potential applications within the energy industry.
A network analysis of the semantic evolution of ‘fruit’ and ‘stone’ in Tibeto-Burman languages
Authors: Li Yu , Qiu Mengyang
Published: June 2023

The lexemes ‘fruit’ and ‘stone’ are known as the origins of the numeral classifiers for small round objects in many Tibeto-Burman languages. This paper employs a correlation-based network construction method to investigate the colexification networks of the two concepts in 58 + 68 Tibeto-Burman languages. A total of 104 concepts colexified with ‘fruit’ and 99 concepts colexified with ‘stone’ are organized into macro semantic classes. Semantic networks on the basis of the similarities in colexification patterns of concepts, as well as languages networks on the basis of the similarities in colexification patterns of languages, are constructed for ‘fruit’ and ‘stone’, respectively. The results indicate that classifiers for small round objects evolved from either ‘fruit’ or ‘stone’ are directly colexified with class terms in compound nouns denoting varieties of fruits/stones and the shape class of small round objects, indicating that they are diachronically related. However, ‘fruit’ and ‘stone’ differ significantly in their modes of deriving a classifier. Moreover, languages that have developed classifiers from ‘fruit’ are mostly from the Ngwi subgroup, whereas languages whose classifiers are colexified with ‘stone’ evolved independently.
Antecedents of mind wandering states in healthy aging and mild cognitive impairment

Objective: Mind wandering refers to periods of internally directed attention and comprises up to 30% or more of our waking thoughts. Frequent mind wandering can be detrimental to ongoing task performance. We aim to determine whether rates of mind wandering change in healthy aging and early-stage cognitive impairment and how differences in mind wandering contribute to differences in cognitive performance.Method: We administered a standard behavioral task, the Sustained Attention to Response Test or SART, to measure mind wandering in healthy younger adults (N = 66), healthy older adults (N = 52), and adults with cognitive impairment (N = 37), that was completed daily for 3 weeks. SART performance was deconstructed into three distinct “states” of mind wandering based on an established framework.Results: Generally speaking, averaged across three weeks of testing, mind wandering was lower in healthy aging relative to younger adults but higher in cognitive impairment, although the specific patterns varied across mind wandering states. Multiple states of mind wandering also predicted working memory performance, however reaction time variability tended to be the best predictor based on AICc model comparisons. Each state was also modestly associated with different dispositional factors including mood, fatigue, open-mindedness, and agreeableness.Conclusions: Patterns of mind wandering change across healthy aging and cognitive impairment and are related to individual differences in multiple dispositional factors and also memory performance. These results suggest that different states of mind wandering should be measured and accounted for when modeling cognitive change in healthy and pathological aging.
Peace is a form of cooperation, and so are the cultural technologies which make peace possible
Authors: Lie-Panis Julien , André Jean-Baptiste
Published: June 2023

While necessary parts of the puzzle, cultural technologies are insufficient to explain peace. They are a form of second-order cooperation---a cooperative interaction designed to incentivize first-order cooperation. We propose an explanation for peace-making cultural technologies, and therefore peace, based on the reputational incentives for second-order cooperation
Redrawing women’s later-inlife desires: Representations of ageing femininities, intimacies and the promise of happiness in graphic novels
Authors: De Vuyst Sara
Published: June 2023

This article explores representations of ageing femininities and later-in-life intimacies based on a critical, contextualised reading of two graphic novels. Narratives of later life are deeply entangled with notions of happiness. While ageing has usually been associated with decay, loss and an irreversible path to unhappiness, in recent years, there has been a shift towards a more rosy picture of an active, social, happy and fulfilling later-in-life. These happiness scripts contain a set of gendered instructions on how to achieve the good life in old age. For ageing women, they include expectations about beauty and the body, sexual desires and the temporal organisation of the life course. This article draws on Sara Ahmed’s critique on the disciplinary dynamics of the promise of happiness and the work that emotions do to value certain bodies, expressions of sexuality and life choices as good for older women and others as bad. The study found that the two graphic novels analysed ‘Bloesems in de herfst’ (Blossoms in Autumn, 2018) by Zidrou and Aimée De Jongh and ‘Bingo Love’ (2018) by Tee Franklin and Jen St-Onge, both confirm and challenge normative ideas about gender, ageing and sexuality. However, while both graphic novels redraw some lines of the prevailing scripts of happiness for ageing women, they do not erase them entirely from the frame. In the end, I will take the discussion one step further by reflecting on how representations of older women can destabilise norms about gender, sexuality and ageing and subvert disciplinary narratives about later life happiness.

Mandarin (Citrus reticulata) is the major sub-tropical fruit popularly grown in slopy terraces of mid-hills which has high domestic and foreign market potentialities. Scientific studies are hardly carried out to assess the socio-economic aspects of mandarin production in this area. So, this research was aimed to assess the production and profitability of mandarin production in Salyan district.  For this, 61 respondents of Baghchaur municipality and 59 of Chhatreshwari rural municipality were selected using random sampling procedure which makes altogether 120 respondents in the study area. Pretested semi structured questionnaire were asked with farm decision makers for primary data collection. Collected data were encoded in MS excel version 2021, and required inferences on socio-economic and demographic characteristics, BC ratio, cobb-douglas production function and problem ranking were made by using SPSS version 26. Independent t test was used to compare the means between two municipalities. The results revealed that the annual mandarin production was 3560.58 Kgs per household with productivity of 14.60 tons per hectare. Average annual variable cost of production and revenue were NRs 227309.41 and NRs 988963.52 per hectare respectively. BC ratio was 5.07 indicating it as profitable business with the benefit of NRs 4.07 per rupee invested.  Among the various determinants, cost of organic manure, human labor and plant protection materials had significantly increased while cost of irrigation had decreased the returns from the enterprise at different significance levels. The return of scale was 0.936 indicating decreasing rate of return of mandarin production.
