Published: August 2022

Fractionation of stable isotopes in precipitation runs through the water cycle, and deuterium excess is a second-order parameter linking water-stable oxygen and hydrogen isotopes. It is strongly influenced by under-cloud evaporation in unsaturated air, especially in arid climates. Based on the improved Stewart model, this study used 670 precipitation stable isotope data and measured meteorological element data from 11 sampling points from January 2018 to September 2019 to verify the existence of sub-cloud secondary evaporation in the Shiyang river basin and quantitatively calculate the intensity of sub-cloud secondary evaporation and its influence on precipitation stable isotopes. The study used the vapor flux and the improved Lagrangian model to track the moisture source of precipitation and analyze the influence of the moisture source of different paths on the stable isotopes of precipitation. Therefore, this study is helpful to understand the evapotranspiration loss mechanism and recharge mechanism of moisture in the watershed. The results showed that there is sub-cloud secondary evaporation in the Shiyang River Basin, and from the seasonal scale, the sub-cloud secondary evaporation is stronger in spring and summer, but weaker in autumn and winter, which makes heavy isotopes enriched in spring and summer and depleted in autumn and winter. From the perspective of spatial distribution, the sub-cloud secondary evaporation is stronger in the midstream and downstream of the Shiyang river, resulting in more enrichment of heavy isotopes. In the vertical direction, the sub-cloud secondary evaporation at 850–700 hPa is the strongest, which enriches the heavy isotope in this layer and reduces the deuterium excess. In addition, the main moisture source of precipitation in the Shiyang River Basin is the westerly air mass, and the mid and high-latitude land sources contribute more moisture to the precipitation. However, the supply of the sea source is very limited, which makes the deuterium excess of precipitation higher and does not show regional consistency and seasonality well.

Rivers are important sites for carbon (C) transport and critical components of the global C cycle that is currently not well constrained. However, little is known about C species’ longitudinal and temporal changes in large tropical rivers. The Usumacinta River is Mexico’s main lotic system and the tenth largest in North America. Being a tropical river, it has a strong climatic seasonality. This study aims to evaluate how organic (DOC and POC) and inorganic (DIC and PIC) carbon change spatially and seasonally along the Usumacinta River (medium and lower basin) in rainy (RS-2017) and dry (DS-2018) seasons and to estimate C fluxes into the southern Gulf of Mexico. Concentrations of DOC, POC, DIC, and PIC ranged from 0.88 to 7.11 mg L−1, 0.21 to 3.78 mg L−1, 15.59 to 48.27 mg L−1, and 0.05 to 1.51 mg L−1, respectively. DOC was the dominant organic species (DOC/POC > 1). It was ~doubled in RS and showed a longitudinal increase, probably through exchange with wetlands and floodplains. Particulate carbon showed a positive relationship with the total suspended solids, suggesting that in RS, it derived from surface erosion and runoff in the watershed. DIC is reported for the first time as the highest concentration measured in tropical rivers in America. It was higher in the dry season without a longitudinal trend. The C mass inflow–outflow balance in the RS suggested net retention (DOC and POC sink) in floodplains. In contrast, in the DS, the balance suggested that floodplains supply (C source) autochthonous DOC and POC. The lower Usumacinta River basin is a sink for DIC in both seasons. Finally, the estimated annual C export for the Usumacinta-Grijalva River was 2.88 (2.65 to 3.14) Tg yr−1, of which DIC was the largest transported fraction (85%), followed by DOC (10%), POC (4%), and PIC (<1%). This investigation is the first to present the C loads in a Mexican river.

Published: August 2022

Open-channel bifurcations are the most common water diversion structures in irrigation districts. In irrigation water conveyance, water transport efficiency and sedimentation are primary concerns. This study accordingly analyzes the influence of open-channel bifurcations on water delivery in irrigation areas. Herein, the three-dimensional flow at an open-channel bifurcation was studied via numerical simulations using FLOW-3D software and including 15 sets of working conditions. The hydraulic characteristics of the recirculation zone and flow structures in the vicinity of the open-channel bifurcation were analyzed. Equations for the flow diversion width of the surface and bottom layers in the trapezoidal channel were then obtained. The flow diversion widths along the water depth were found to differ between trapezoidal and rectangular channels. The results also show that open-channel bifurcations considerably influence the flow velocity in the main channel. The flow velocity in the recirculation zone of open-channel bifurcations was small, but the pulsation velocity and the turbulent kinetic energy were large. The energy dissipated in this area was relatively large, which was not conducive to channel water delivery. This study provides a reference for channel optimization and operation management in irrigation districts.
Technical Feasibility of Heavy-Duty Battery-Electric Trucks for Urban and Regional Delivery in Germany—A Real-World Case Study
Authors: Link Steffen , Plötz Patrick
Published: August 2022

Cutting greenhouse gas emissions to comply with the Paris Agreement is challenging for road freight. While heavy-duty battery-electric trucks (BET) promise tremendous and immediate reduction potential, literature increasingly confirms technical feasibility in general, and several manufacturers launched BET models. However, their real-world application is still being questioned by fleet owners due to the limited range or payload penalties. Thus, our case study aims to assess the technical feasibility of urban and regional delivery in Germany based on real-world and per-vehicle operational data that feed into an energy simulation with Monte-Carlo modeling. Our results demonstrate the importance of vehicle-specific examination for the right battery capacity that ideally matches the vehicle’s operating profile. We find that full electrification may be most accessible for 18-t and 26-t rigid solo trucks, soon followed by tractor-trailers, while truck-trailers turn out as most challenging. With up to 600 kWh battery capacity available in all truck classes, we find nearly 40% of all transport performance and 60% of all diesel trucks may be replaced with BET—while already 400 kWh is sufficient for half of all trucks. Additional measures such as intermediate charging and adjusted and more flexible truck-tour allocation may significantly accelerate electrification.
Where to Charge Electric Trucks in Europe—Modelling a Charging Infrastructure Network
Authors: Speth Daniel , Sauter Verena , Plötz Patrick
Published: August 2022

Heavy-duty trucks account for 27% of the European greenhouse gas emissions in the transport sector. To decarbonize road freight transport, the European Union plans to build a fast charging network for trucks. This paper presents two scenarios, covering European highways with charging stations at regular intervals every 50 or 100 km along the most important highways. For each location, the required number of charging points at 15% battery electric trucking is calculated individually using queueing theory. A third scenario takes into account the infrastructure ramp-up in 2025 and assumes a share of 5% battery electric trucking in a network with a 100 km distance. We define a network of 660 (100 km distance) or 1468 stations (50 km distance). Depending on the scenario and the individual station, the projected number of charging points per station varies between 1 and 18 in 2030. The results give a first insight into what a fast charging infrastructure for trucks in Europe might look like. In particular, we show that large charging stations with more than ten charging points could be necessary in the next few years. This knowledge might help to design future charging infrastructure for electric road freight transport.

Изучены биохимический статус и динамика роста телят в молочный период выращивания при использовании в кормлении ферментативно-пробиотического препарата «Румит» (пробиотик). Для изучения влияния добавки был проведен научно-хозяйственный опыт в условиях сельхозпредприятия в Вологодской области на 20 телятах черно-пестрой породы в возрасте 1,5 мес, разделенных на 2 группы по принципу пар-аналогов. Молодняк контрольной группы получал основной рацион, животным опытной группы на протяжении эксперимента (90 дней) скармливали дополнительно в качестве добавки пробиотик в количестве 15 г на 1 голову в сутки. У телят, получавших пробиотик, отмечено повышение в крови содержания общего белка на 7,8% (Р<0,05), глюкозы — на 21,5% (Р<0,01), снижение мочевины на 12,5% (Р<0,05), билирубина и холестерина — на 5,5 и 11,8% (Р<0,05) соответственно. При анализе динамики роста молодняка в молочный период выращивания более высоким абсолютным и среднесуточным приростом, соответственно на 3,8 и 4,6%, характеризовались особи опытной группы по сравнению с контролем. В результате проведенных исследований установлено, что применение изучаемого биопрепарата телятам-молочникам положительно повлияло на обменные процессы в их организме, а также на интенсивность роста животных.

We have studied the biochemical status and growth rates of calves during the dairy growing period when using the enzymatic-probiotic preparation “Rumit” in feeding. To study the effect of the additive, we have conducted a scientific and economic experiment in the conditions of the Agricultural Production Co-operative “Andoga Kolkhoz” of the Kaduysky district of the Vologda Oblast on 20 calves of black-and-white breed at the age of 1.5 months, divided into two groups according to the principle of pairs of analogues. The calves of the control group received the main diet, the animals of the experimental group during the experiment (90 days) in addition to the main feed, the probiotic “Rumit” was fed 15 g per head per day as an additive. Calves receiving the biopreparation “Rumit” in addition to the main feed have showed an increase in the blood content of total protein by 7.8% (p0.05), glucose by 21.5% (P˂0.01). We have found a decrease in blood urea by 12.5% (P˂0.05), bilirubin and cholesterol by 5.5 and 11.8% (P˂0.05), respectively. When analyzing the calves’ growth rates during the dairy growing period, calves of the experimental group are characterized by higher absolute and average daily increments, and the difference with the control group is 3.8 and 4.6%, respectively. As a result of the conducted research, we have found that feeding the studied biological product to dairy calves had a positive effect on metabolic processes in the body, as well as on the intensity of animal growth.
Patient experiences of GP-led colon cancer survivorship care: a Dutch mixed-methods evaluation
Authors: Vos Julien AM , van Miltenburg Vera E , Beverdam Frédérique H , van Weert Henk CPM , van Asselt Kristel M
Published: August 2022

Background

Colon cancer survivorship care constitutes both follow-up and aftercare. GP involvement may help to personalise care.

Aim

To explore patients’ experiences of GP-led versus surgeon-led survivorship care.

Design and setting

Patients with stage I to III colon cancer were recruited from eight Dutch hospitals and randomised to receive care by either the GP or surgeon.

Method

A mixed-methods approach was used to compare GP-led care with surgeon-led care. After 1 year the Consumer Quality Index (CQI) was used to measure quality aspects of care. Next, interviews were performed at various time points (3–6 years after surgery) to explore patients’ experiences in depth.

Results

A total of 261 questionnaires were returned by patients and 25 semi-structured interviews were included in the study. Overall, patients were satisfied with both GP-led and surgeon-led care (ratings 9.6 [standard deviation {SD} 1.1] versus 9.4 [SD 1.1] out of 10). No important differences were seen in quality of care as measured by CQI. Interviews revealed that patients often had little expectation of care from either healthcare professional. They described follow-up consultations as short, medically oriented, and centred around discussing follow-up test results. Patients also reported few symptoms. Care for patients in the GP-led group was organised in different ways, ranging from solely on patient’s initiative to shared care. Patients sometimes desired a more guiding role from their GP, whereas others preferred to be proactive themselves.

Conclusion

Patients experienced a high quality of colon cancer survivorship care from both GPs and surgeons. If the GP is going to be more involved, patients require a clear understanding of roles and responsibilities.
UK newspapers ‘on the warpath’: media analysis of general practice remote consulting in 2021
Authors: Mroz Gilly , Papoutsi Chrysanthi , Greenhalgh Trisha
Published: August 2022

Background

Following a large-scale, pandemic-driven shift to remote consulting in UK general practice in 2020, 2021 saw a partial return to in-person consultations. This occurred in the context of extreme workload pressures because of backlogs, staff shortages, and task shifting.

Aim

To study media depictions of remote consultations in UK general practice at a time of system stress.

Design and setting

Thematic analysis of national newspaper articles about remote GP consultations from two time periods: 13–26 May 2021, following an NHS England letter, and 14–27 October 2021, following a government-backed directive, both stipulating a return to in-person consulting.

Method

Articles were identified through, and retrieved from, LexisNexis. A coding system of themes and narrative devices was developed iteratively to inform data analysis.

Results

In total, 25 articles reported on the letter and 75 on the directive. Newspaper coverage of remote consulting was strikingly negative. The right-leaning press in particular praised the return to in-person consultations, depicting remote care as creating access barriers and compromising safety. Two newspapers led national campaigns pressuring the government to require GPs to offer in-person consultations. GPs were quoted as reluctant to return to an ‘in-person by default’ service (as it would further pressurise a system already close to breaking point).

Conclusion

Remote consultations have become associated in the media with poor practice. Some newspapers were actively leading the ‘war’ on general practice rather than merely reporting on it. Proactive dialogue between practitioners and the media might help minimise polarisation and improve perceptions around general practice.

Published: August 2022

The relevance of scientific work is determined by the need to identify and justify the syntactic-semantic connection between contemporary musical art and the socio-cultural world space. The aim of the article is a comparative analysis of tradition-innovation relation in the context of musical art in modern Ukraine on the example of leading musical projects. Achievement of the objectives was possible due to the use of a number of methods of scientific research, among which analysis, synthesis, generalization, and systematization, as well as the method of comparativism. The relevance of studying the correlative connection between traditional Ukrainian cultural space and global artistic trends, gravitating toward pluralism and multiculturalism, as well as the establishment of intercultural communication was confirmed. The novelty of the scientific article consists in the study of musical projects as objects of the sphere of art for the identification of Ukrainian tendencies. The practical value of the work is focused on providing the scientific space with qualitative information content on the topic of the formation of Ukrainian festivals and explaining their specificity. Thus, the authors have summarized a comprehensive cultural research and identified the prospects for further developments with the online measurement of audiovisual int of modern Ukraine.
The Predictive Power of Biological Markers for Malignant Thyroid Nodules. Single-Center Experience
Authors: CAPOGLU Recayi , BAYHAN Zulfu , GÖNÜLLÜ Emre , COSKUN Murat , HARMANTEPE Ahmet Tarık , KUCUK Furkan , DEMİR Hakan
Published: August 2022

Background: Thyroid nodules are mostly benign. Although it varies by region, 5.4% of nodules in men and 6.5% of nodules in women may be malignant. In rural regions where a radiologist, an endocrine surgeon, a cytologist, and an endocrinologist are not present, difficulties may be experienced in the management of thyroid nodules.

Objectives: This present study aims to determine if it is possible to comment on whether the nodule is malignant by evaluating the biological markers in patients with thyroid nodules.

Methods: We reviewed retrospectively the data of patients between January 2019 and September 2020 who underwent total thyroidectomy in terms of thyroid ultrasonography results, thyroid fine-needle aspiration biopsy results, neutrophil, platelet, lymphocyte, red blood cell, and mean erythrocyte volume (MCV) values, histopathological examination results of thyroid specimens. Subsequently, we calculated Mentzer index, Systemic immune-inflammatory index, and neutrophil-lymphocyte ratio for each patient.

Results: 140 patients were included in the study. 110 (78.6%) of the patients were female and 30 (21.4%) were male. The mean age of the patients was 48 ± 12.5 (20-76). There was no statistically significant difference in Mentzer index, Systemic inflammatory index, and neutrophil-lymphocyte ratios between patients with malignant and benign thyroid nodules.

Conclusion: Biological markers have limited predictive power in the management of thyroid nodules. Therefore, the use of biomarkers that we have studied in the treatment of thyroid nodules does not seem possible at present.
Gravity-Dependent Animacy Perception in Zebrafish

Published: August 2022

Biological motion (BM), depicted by a handful of point lights attached to the major joints, conveys rich animacy information, which is significantly disrupted if BM is shown upside down. This well-known inversion effect in BM perception is conserved in terrestrial vertebrates and is presumably a manifestation of an evolutionarily endowed perceptual filter (i.e., life motion detector) tuned to gravity-compatible BM. However, it remains unknown whether aquatic animals, living in a completely different environment from terrestrial animals, perceive BM in a gravity-dependent manner. Here, taking advantage of their typical shoaling behaviors, we used zebrafish as a model animal to examine the ability of teleosts to discriminate between upright (gravity-compatible) and inverted (gravity-incompatible) BM signals. We recorded their swimming trajectories and quantified their preference based on dwelling time and head orientation. The results obtained from three experiments consistently showed that zebrafish spent significantly more time swimming in proximity to and orienting towards the upright BM relative to the inverted BM or other gravity-incompatible point-light stimuli (i.e., the non-BM). More intriguingly, when the recorded point-light video clips of fish were directly compared with those of human walkers and pigeons, we could identify a unique and consistent pattern of movements in the vertical (gravity) direction. These findings, to our knowledge, demonstrate for the first time the inversion effect in BM perception in simple aquatic vertebrates and suggest that the evolutionary origin of gravity-dependent BM processing may be traced back to ancient aquatic animals.

Published: August 2022

Maize (Zea mays L.) is the most abundantly produced and consumed cereal in the world. Major challenge in maize production in Africa is low soil fertility due to lack of sustainable soil fertility restoring inputs among others. This study investigated the potentials of Moringa-banana-maize mix, a biodegradable, environment friendly and abundantly available free gifts of nature in soil fertility improvement. The objective of this study was to investigate the effects of the mixture of Moringa olifera leaves (MO) +Banana Peels (BL) +Maize Stalks (MS) on yield and profitability of maize production. Specifically, to choose the right combination of the mix and determine the correct mode of application. Field and screen house experiments were conducted in 2020 planting seasons, at the Teaching and Research Farm of Kwara State University, Malete. Four treatments were considered and each represented a technology on field/screen trials. These include; A=100N+40P+30K, B= 120N+50P+40K, C= 70N+30P+ 20K and the control using the national recommended dose of 90kg/ha of NPK fertilizer (for comparison).
Comparative Study of three Clustering Algorithms for Microarray Data

Published: August 2022

High throughput genomic data analysis is becoming an increasingly integral part of biomedical research. The information derived from gene expression analysis helps in diagnosing the treatment modality given to the patient. However, the amount of data is humongous and becomes complex to examine manually. Unsupervised machine learning algorithms perform complex tasks on an unlabelled data by clustering to comprehend the underlying structure and behaviour of the pattern. Clustering microarray data, examines the differential expressed genes found by grouping the genes based on the similarity of the expression values. In this study, we propose to elucidate the best clustering algorithm for gene expression data on various clinical conditions. The proposed study was carried on three gene expression datasets of Severe acute respiratory syndrome, Amyotrophic lateral sclerosis and Parkinson’s disease. Differentially expressed genes were found at three p-values 0.01, 0.05, 0.001 and the most significant number of genes were retrieved at p-value 0.05. We experimented the differential expressed genes on three clustering algorithms, namely Hierarchical clustering, k-means clustering and fuzzy clustering of the three diseases. The performance of the three clustering algorithms was evaluated using the internal validity index, wherein Hierarchical clustering was found to be best for gene expression data.

Published: August 2022

The Commission of National Education (Komisja Edukacji Narodowej), which was established in 1773, introduced fundamental changes relating to organisation and the curriculum in the Polish education system. The Commission constituted a kind of Ministry of Education, which exercised supervision over all the schools in the Crown and the Grand Duchy of Lithuania. The hierarchy was as follows - the Main Crown Schools in Kraków and Grand Duchy of Lithuania in Vilnius, subordinate to the Commission, were in turn superior to divisional schools, including subdivisional schools, and these in turn were superior to parish schools. The changes in the curriculum in the Main Schools were focused predominantly on broadening knowledge in the field of mathematics, natural sciences, and technical skills, which was brought to life in the form of Collegium Physicum and its respective departments, e.g. the departments of architecture, mechanics, and hydraulics, and their respective offices, gathering tools, equipment, and models facilitating the sharing of knowledge through presentations. Similar curricular changes were implemented in secondary schools. It was the first time that natural sciences with technical elements had been introduced on such a wide scale to the curriculum. The official instructions enabled the standardisation of the curriculum in all schools. The characteristic feature of the curriculum was its utilitarianism, as, when teaching each subject, particular attention was paid to developing students' skills in using acquired theoretical knowledge in practice. The changes were introduced in a systematic manner. The first step covered the preparation of the curriculum and instructions concerning its implementation, which was followed by teacher training. This was of paramount significance to the teaching of mathematics, natural sciences, and technical subjects. The class books were arranged by putting them out to tender, and often the works by foreign authors were used. The new curriculum modernised education, broadening students' knowledge of mathematics, natural sciences, and technical subjects, and preparing them for the huge civilisational changes brought by the 19th century. It aroused interest in technology, which was entering nearly all spheres of socio-economic life on a bigger and bigger scale. It proved useful in the 19th century, when Polish students went to technical colleges abroad in great numbers due to the lack of technical universities in the Kingdom of Poland and the Prussian Partition.

Africa’s Food Security under the Shadow of the Russia-Ukraine Conflict
Authors: Hatab Assem Abu
Published: August 2022

The Russian invasion of Ukraine in February 2022 has emerged as an exogenous shock to global food supply chains, which foreshadows worrying impacts on Africa’s food security and nutrition, and threaten to derail national and global efforts to end hunger and poverty and to achieve sustainable development goals on the continent. This article provides an early assessment of the implications of the invasion for Africa’s food supply chains and food security. Two particularly aggravating factors, which explain the current and likely future impact of the invasion on Africa’s food security are discussed: the timing of the invasion and the two parties involved in the conflict. The article underlines four major channels by which the invasion disrupts African food supply chains: energy markets and shipping routes, availability and prices of agricultural production inputs, domestic food price inflation, and trade sanctions and other financial measures. In addition, the article considers the risk of social and political unrest that disruption to food supply chains and spikes in domestic food prices may inflame. Finally, the paper briefly discusses options for short- and long-term responses by African governments and their development partners to mitigate the repercussions of the conflict on food supply chains, boost food and nutrition security, and build resilience of Africa’s food systems.

Published: August 2022

Diabetes mellitus is a disease caused by high blood glucose levels. Blood glucose is a sugar that functions as an energy source for humans, formed from carbohydrates consumed and then stored as glycogen in the liver and muscles. Examining blood glucose levels can be done in two ways, namely using a photometer and a glucometer. This study aimed to determine differences in the results of blood glucose checks measured using a photometer and glucometer. The research was conducted with an analytic observational design with a cross-sectional approach. The study was conducted in June 2022. The population in this study were all Prolanis participants at the Klirong 1 Public Health Care Center. The sampling technique in this study used the accidental sampling technique. The data analysis used paired sample T-test. The results of the blood glucose checks using a photometer and glucometer showed a p-value (0.000) and alpha value (0.05).

In the case of tangible cultural heritage items made of natural fibres, biodegradation due to microorganisms can lead
over time to undesirable deterioration, including physical, mechanical and chemical damage as well as aesthetic
alteration of materials. In this study, the antifungal activity tests were performed on 3 old maps (on silk, on canvas and
on paper) using the AATCC 30-2004 test method. Map samples were immersed in a chitosan solution (10 g/l) and
evaluated using Scanning Electron Microscopy (SEM) with a Field Emission Scanning Electron Microscope (ULTRA 55,
ZEISS). The process showed that, due to its antimicrobial effect, chitosan treatment is effective for removing external
agents and microorganisms present on fibre surfaces. The technique is simple, efficient and the results indicated that
chitosan can be transformed into a very good and cheap antimicrobial solution for the conservation and preservation of
heritage objects.

Online distance learning (ODL) is one extension of the distance learning approach introduced by the Department of Education (DepEd) as part of its learning continuity in the new normal (COVID – 19 times). Despite the advantages brought by online learning in continuing learners’ learning experiences and improving learners’ academic performance during the pandemic, it is still of vital importance to examine what factors are sensitive to changes in learner’s online academic performance. In this study, sensitive factors affecting online academic performance are examined through the lens of machine learning (ML) methods: Boruta algorithm (BA) for feature selection; multilayer perceptron neural network (MLP NN) for model formulation; and partial derivatives method (PDM) for sensitivity analysis. Data used in the analysis are responses in the survey participated by N = 978 senior high and junior school students of a private high school institution in the Philippines. Out of eighteen factors considered in the analysis, BA revealed only six relevant factors that contributes greater information to changes in student's online academic performance. Formulated MLP NN model achieved a high testing accuracy of 0.932 with a kappa coefficient of 0.891 and an f – measure of 0.924, that aided the sensitivity analysis using PDM to have better results. Sensitivity analysis showed that motivation and mental well – being are the most sensitive factors affecting both below average and above average online academic performance.
