Authors: Mazur Victor , Tkachuk Oleksandr , Pantsyreva Hanna , Demchuk Olga
Published: January 2022

The widespread use of water in crop production and agriculture is due to a significant increase in yields during the watering of agricultural crops, as well as the transfer of pesticides and mineral fertilizers to plants and soil by water. One of the ways to improve the quality of water used in crop production is to structure it. An urgent task is to study the effect of structured water delivered to agricultural crops by watering or spraying on the yield, quality of the resulting products and agroecological condition of the soil. Field studies on pea crops were conducted at experimental sites of the Vinnytsia National Agrarian University, laboratory studies were conducted in accredited laboratories for monitoring the quality, safety of feed and raw materials of the Institute of Feed Research and Agriculture of Podillya of the National Academy of Agrarian Sciences of Ukraine and the testing centre of the Vinnytsia branch of the state institution “Institute of Soil Protection of Ukraine”. When watering peas with structured water, its yield increases by 42.3% compared to the version without water application and by 22.3% compared to the version with watering with plain water. Pea seeds when watered with structured water have a lower content of crude protein by 0.43 %, crude fat – by 0.09%, crude ash – by 0.63%, but a higher content of crude fibre by 0.11% and nitrogen-free extractives – by 0.99% compared to the version without water. The content of humus in the soil, when watered with structured water, was lower than in the version without water by 0.04%, lightly hydrolysed nitrogen – by 8.0%, mobile phosphorus – by 20.0%, exchangeable potassium – by 7.9%, the reaction of the soil solution – by 0.2 pH, hydrolytic acidity – by 21.7%, the concentration of mobile lead – by 18.4%. However, the concentration of mobile cadmium increased by 43.8% and soil moisture – by 4.3%. When comparing the indicators of the agroecological state of the soil, which was watered with structured and plain water, it was found that watering with structured water reduces the content of humus by 0.03%, lightly hydrolysed nitrogen – by 2.3%, mobile phosphorus – by 20%, exchange potassium – by 9.7%, hydrolytic acidity – by 7.7%, the reaction of the soil solution – by 0.3 pH, but increases the content of mobile lead by 10.9%, mobile cadmium – by 25.0% and increases the moisture content in the soil – by 2.7%

This paper analyses the impact of the armed conflict in Ukraine on the development of the agricultural sector and changes in average prices of agricultural products, and also identifies a possible relationship between changes in prices for agricultural products and financial expenditures for defence needs. The paper also investigates the possible relationship between changes in military spending, gross harvest of cereals and legumes, harvested and threshed area, their yield levels. The study considers how the presence and duration of armed conflict in the country affects: macroeconomic indicators, intensity of hostilities and their localisation in areas of economic activity, gross domestic product (GDP), government expenditures, export-import indicators; household expenditures and domestic investment, consumer and household expenditures. All this, indirectly, has an impact on fluctuations in average prices of products of different sectors of agriculture sold by enterprises. The study takes into account the importance of the agricultural sector of Ukraine, which is a significant part of the country GDP. The dependence of military spending on the size of GDP is the reason for analysing the relationship between the impact of the existing armed conflict on changes in the state of agriculture in Ukraine. One of the results of such actions was also the spending of more money on the purchase of agricultural products to support the defence needs of the state, etc. Therefore, to understand the magnitude of the impact of gross harvest factors, crop yields, and agricultural land volumes on the pricing of agricultural output using the method of statistical equation dependencies, the findings of the relevant analysis can be used as a basis for developing approaches, methods, and techniques to improve crop yields, or – initiate economic development of the country by increasing agricultural crop yields

Health connected is a technology that links medical devices, telecommunications and security techniques. It empowers patients to be observed and treated remotely from their homes. Patient’s healthcare records with a connected healthcare system should be stored securely before transmitted for further investigation and interpretation. Electrocardiogram (ECG) is the clinical method utilized to screen heart execution and utilized for the detection of various arrhythmias. For diagnostic purposes, individuals with a background of heart diseases have long records of ECGs, which results in the requirement of a large amount of storage space and labor. Hence, there is a requirement for a system that involves digital signal processing and signal security so that the spared information is made sure about at one spot and an only authentic individual can see and utilize this ECG signal for additional findings. This study presents a set of security solutions that can be deployed in a connected healthcare territory, which includes the fully homomorphic encryption (FHE) techniques used to secure the ECG signals. The study helps the medical provider to record ECG signals confidentially and to prevent mistreatment. The study focuses on Pan and Tompkins algorithm methods for the detection of the ECG Signal. As a result, the output of the Pan and Tompkins algorithm for ECG signal processing with the FHE technique shows a sensitivity of 92.59% and a positive prediction of 90.00%.

The rapid increase in the world's population has made efficient use of water an urgent necessity. The objective of the research was to evaluate the effect of deficit irrigation and planting density on morphophysiological and productive indicators of the hybrid Py 4039 corn crop with drip irrigation. A bifactorial experiment was developed with a 4x3 arrangement with 12 treatments, four percentages of the raw sheet calculated with the Cropwat 8.0 software and three planting densities were evaluated. An experiment was developed in divided plots. In the main plots the sheets were evaluated at 120, 100, 90 and 80% of the total gross layer and in the secondary plots the planting densities of 66 666, 50 000 and 40 000 plants per ha. The morphophysiological variables measured were plant height, stem diameter, number of leaves and corn insertion height, and the productive variables: average grain weight and estimated yield. The efficient use of water was estimated by the relationship between the corn production obtained and the volume of water consumed. The results were evaluated by means of a bifactorial analysis of variance, with the statistical program (STATGRAPHICS) Statistical Analysis System. The results obtained show that with an irrigation sheet of 376.31 mm and a density of 66 666 plants, an average yield of 13.49 t.ha-1 is reached, and an efficiency in the use of water of 8.98 kg of corn produced per m-3 of water applied.

Behind the Cancellation of Green Refinery Cooperation Between Pertamina and Eni
Authors: Abdul Rachman Muhammad Fauzi , Yani Yanyan Mochamad , Montratama Ian
Published: January 2022

Pertamina and Eni faced double strike problems. The Italian government did not grant the license for building Indonesian crude palm oil (CPO) based green finery to Eni-Pertamina as most Indonesian CPO producers do not possess RSPO certificates and the EU restricts the use of CPO. The policies resulted in opportunities loss for Pertamina and Eni in 2019. This qualitative paper examined the logical reasons behind the Italian government decision by two levels of analysis, domestic and regional locus. The finding shows that domestically, political circumstances among parties and figures, other than CPO commodities farmers, played a significant role in the cancellation. The historical instability in Italy domestic political situation also brought it closer to revocation. On another level, the ups and downs of Italy-the EU relations before and during Conte I and Conte II government were a regional reason behind it.

Revitalising Jiri Technical School in a Dramatically Changed Context: Governance, Management and Employability
Authors: Kafle Agni Prasad , Pfeiffer Hansruedi
Published: January 2022

This paper examines two assumption: First, whether inadequate practical training, including much shortened apprenticeship training, has negatively affected the employability and incomes of graduates of TVET institutions in Nepal, and the second, whether it is good institutional management and governance that provide the systems for quality training and positive labour market outcomes. Tracer studies and an institutional assessment of Jiri Technical School (JTS) confirm the first assumption. The review of select literature on institution building and the benchmarking of JTS’ operative practices against those of high performing educational institutions (in India) confirm the second assumption. It is argued that poor management and governance of TVET institutions drifts the mission of Technical Schools away from their initial socio-economic mandate: the provision of skilled human resource and access to qualification opportunities to the youth having the aptitudes for such an education. Social rather than labour market demand with corresponding politics is one major force for such deviation. To revitalise the JTS, it is proposed to bank on the federalisation of the TVET governance system to professionalise Board, Management and teachers for enhanced labour market outcomes in closer cooperation between actors from the education and employment systems.

Authors: Khan M. Zakir Saadullah , Mazumder Sharna
Published: January 2022

The aim of this study is to measure the efficiency of higher educational institutions and investigate the comparative efficiency of public and private higher education in Bangladesh. Using data envelopment analysis (DEA), technical efficiency of 15 public universities and 20 private universities of Bangladesh are evaluated over the period 2008-2018. The empirical results reveal that public universities on an average operate between 56.2 to 80.7 percent level of technical efficiency while the private universities between 49.1 to 77.6 percent level over the study period. That is, universities in Bangladesh, on an average, do not operate efficiently in terms of resource utilization. Over the years only 33% public universities and 25% private universities are found efficient. The inefficient universities can improve their efficiency by utilizing full capacity of the inputs or reducing the amount of inputs at the estimated inefficiency rate of the respective universities. Findings also show that the public universities have the scope of producing 1.24 to 1.78 times and private universities 1.28 to 2.04 times as much output from the same level of inputs. Special monitoring by the regulatory authorities is required for inefficient universities to enhance their efficiency level.
Level of Perceived Employability of Engineering Students in Kathmandu Valley
Authors: Sharma Amrita
Published: January 2022

The discourse of employability revolves around the mitigation of mismatch between educational outcomes and the job market demand. This discourse is pertinent in engineering education as it is dedicated to producing human resources with the required employability skills. In this context, the students - to whom employability is transformed - are in the central focus. Their perceptions about their abilities in demonstrating and performing in the world of work require attention to connect education and their work. Considering this, the level of perceived employability of the engineering students studying in their final year was measured by using a self-constructed scale in a representative sample of 314 students of Kathmandu valley. The finding shows that the graduating students’ perceived employability was not consolidated and optimised to reflect on their behaviour and practices. It is at the level of ‘emergence’ and ‘presence’, which is thus not enough to see in their abilities to perform better. Therefore, the students were not able to perform as per the expectation of the market.  The key implication of this study is that the gap of work-study transition stipulated to be minimised for the employability of the graduates with their exposure in the world of work.

Using Dictation Techniques to Improve the Eighth-Grade Students’ Listening Comprehension Achievement at SMPN 35 Surabaya
Authors: Vitriyati Laely
Published: January 2022

Dictation is an ancient technique in teaching language becoming one of interesting ways to improve the students’ listening comprehension proposed by Davis & Rinvolucri (1988). This study was aimed to solve the students’ listening comprehension achievement by using dictation techniques as a technique in teaching listening at SMPN 35 Surabaya in the academic year 2020/2021. Classroom Action Research (CAR) was applied in this study in two cycles. In this classroom action research, the technique was divided into note taking and partial dictation. The primary data about students listening achievement were gained from the listening test. Meanwhile, the supporting data were gathered from observation and documentation. The results on students’ activity showed the use of text dictation techniques could improve the eighth-grade students’ activity in listening. Furthermore, In the first cycle of the test’ result, the teaching listening activity was not so good as what was expected. On the average, the percentage of the students’ involvement in the process of teaching listening was only 45% in the first meeting and 50% in the second meeting. But, in the second cycle the percentage of students’ involvement in the process of teaching listening increased from 77% in the first meeting to 80% in the second meeting. This improvement happened because of some revision, they were; choosing the text with familiar story for the students, reading the text more clearly, turning up the volume, and using more gestures in teaching listening technique

Published: January 2022

Abstract. A new empirical parameterization (EP) for multiple groups of primary biological aerosol particles (PBAPs) is implemented in the aerosol cloud model (AC) to investigate their roles as ice-nucleating particles (INPs). The EP describes the heterogeneous ice nucleation by (1) fungal spores, (2) bacteria, (3) pollen, (4) detritus of plants, animals, and viruses, and (5) algae. Each group includes fragments from the originally emitted particles. A high-resolution simulation of a midlatitude mesoscale squall line by AC is validated against airborne and ground observations. Sensitivity tests are carried out by varying the initial vertical profiles of the loadings of individual PBAP groups. The resulting changes in warm and ice microphysical parameters are investigated. Overall, PBAPs have little effect on the ice phase, especially in the convective region. In the stratiform region, increasing the initial PBAP loadings by a factor of 100 resulted in less than 60 % change in ice number concentrations. The total ice concentration is mostly controlled by various mechanisms of secondary ice production (SIP). However, when SIP is artificially prohibited in sensitivity tests, increasing the PBAP loading by a factor of 100 has no significant effect on the ice phase. Further sensitivity tests revealed that PBAPs have little effect on surface precipitation as well as on shortwave and longwave flux.
On the quality of RS41 radiosonde descent data
Authors: Ingleby Bruce , Motl Martin , Marlton Graeme , Edwards David , Sommer Michael , von Rohden Christoph , Vömel Holger , Jauhiainen Hannu
Published: January 2022

Abstract. Radiosonde descent profiles have been available from tens of stations for several years now – mainly from Vaisala RS41 radiosondes. They have been compared with the ascent profiles, with ECMWF short-range forecasts and with co-located radio occultation retrievals. Over this time, our understanding of the data has grown, and the comparison has also shed some light on radiosonde ascent data. The fall rate is very variable and is an important factor, with high fall rates being associated with temperature
biases, especially at higher altitudes. Ascent winds are affected by pendulum motion; on average, descent winds are less affected by pendulum
motion and are smoother. It is plausible that the true wind variability in
the vertical lies between that shown by ascent and descent profiles. This
discrepancy indicates the need for reference wind measurements. With current processing, the best results are for radiosondes with parachutes and pressure sensors. Some of the wind, temperature and humidity data are now assimilated in the ECMWF forecast system.

Published: January 2022

Abstract. Excessive reactive oxygen species (ROS) in the human body is an important factor leading to diseases. Therefore, research on the content of reactive oxygen species in atmospheric particles is necessary. In order to more conveniently and accurately detect the content of reactive oxygen in atmospheric particles hour by hour. Here, to modify the instrument, it is added a DTT experimental module that is protected from light and filled with nitrogen at the end, based on the Monitor for AeRosols and Gases in ambient Air (MARGA). The experimental study found that the detection limit of the modified instrument is 0.024 nmol min−1. And the accuracy of the online instrument is determined by comparing the online and offline levels of the samples, which yielded good consistency (slope 0.97, R2 = 0.95). It shows that the performance of the instrument is indeed optimized, the instrument is stable, and the characterization of ROS is accurate. Meanwhile, reactive oxygen and inorganic ions in atmospheric particles are quantified using the online technique in the northern suburbs of Nanjing. It is found that the content of ROS during the day is higher than that at night, especially after it rains, ROS peaks appear in the two time periods of 08:00–10:00 and 16:00–18:00. In addition, examination of the online ROS and water-soluble ions (SO42−, NO3−, NH4+, Na+, Ca2+, K+), BC and polluting gases (SO2, CO, O3, NO, NOx) measurements revealed that photo-oxidation and secondary formation processes could be important sources of aerosol ROS. This method breakthrough enables the quantitative assessment of atmospheric particulate matter ROS at the diurnal scale, providing an effective tool to study sources and environmental impacts of ROS.

Abstract. Long et al (2021) conducted a detailed study of possible interferents in measurements of surface O3 by UV spectroscopy, which measures the UV transmission in ambient and O3 scrubbed air. While we appreciate the careful work done in this analysis, there were several omissions and, in one case, the type of scrubber used was mis-identified as manganese dioxide (MnO2), when in fact it was manganese chloride (MnCl2). This misidentification led to the erroneous conclusion that all UV-based O3 instruments employing solid-phase catalytic scrubbers exhibit significant positive artifacts, whereas previous research found this not to be the case when employing MnO2 scrubber types. While the Long study, and our results, confirm the substantial bias in instruments employing an MnCl2 scrubber, a replication of the earlier work with an MnO2 scrubber type and no humidity correction is needed.
The first 250 years of the Heinrich 11 iceberg discharge: Last Interglacial HadGEM3-GC3.1 simulations for CMIP6-PMIP4

Abstract. The Heinrich 11 event is simulated using the HadGEM3 model during the Last Interglacial period. We apply 0.2 Sv of meltwater forcing across the North Atlantic during a 250 years long simulation. We find that the strength of the Atlantic Meridional Overturning Circulation is reduced by 60 % after 150 years of meltwater forcing, with an associated decrease of 0.2 to 0.4 PW in meridional ocean heat transport at all latitudes. The changes in ocean heat transport affect surface temperatures. The largest increase in the meridional surface temperature gradient occurs between 40–50 N. This increase is associated with a strengthening of 20 % in 850 hPa winds. The stream jet intensification in the Northern Hemisphere in return alters the temperature structure of the ocean heat through an increased gyre circulation, and associated heat transport (+0.1–0.2 PW), at the mid-latitudes, and a decreased gyre ocean heat transport (−0.2 PW) at high-latitudes. The changes in meridional temperature and pressure gradients cause the Intertropical Convergence Zone (ITCZ) to move southward, leading to stronger westerlies and a more positive Southern Annual Mode (SAM) in the Southern Hemisphere. The positive SAM influences sea ice formation leading to an increase in Antarctic sea ice. Our coupled-model simulation framework shows that the classical "thermal bipolar see-saw'' has previously undiscovered consequences in both Hemispheres: these include Northern Hemisphere gyre heat transport and wind changes; alongside an increase in Antarctic sea ice during the first 250 years of meltwater forcing.
Coupling Human and Natural Systems for Sustainability: Experiences from China’s Loess Plateau

Abstract. Addressing the sustainability challenges facing humanity in the Anthropocene requires the coupling of human and natural systems, rather than their separate treatment. To understand the dynamics of a coupled human and natural system (CHANS) and promote its sustainability, we proposed a conceptual cascade framework of “Pattern-Process-Service-Sustainability”. The use of this framework was systematically illustrated by a review of CHANS research experiences in China’s Loess Plateau (LP) in terms of coupling landscape patterns and ecological processes, linking ecological processes to services, and promoting social-ecological sustainability. The LP is well-known for its historically notorious soil erosion and successful vegetation restoration achieved in recent decades. Vegetation coverage in the LP has increased since 2000 due to ecological restoration. Soil erosion has been well controlled and the sediment deriving from the LP, and flowing into the Yellow River, has greatly decreased; however, overplanting, the introduction of exotic plant species, and the mismanagement of planted vegetation have also led to soil drying in some areas. Ecosystem services, especially for soil conservation and carbon sequestration, have significantly improved, although a trade-off between carbon sequestration and water supply has been identified at multiple scales. Based on the comprehensive understanding of CHANS dynamics, targeted policy and management suggestions are here proposed to support the social-ecological sustainability of the LP. The research experience accumulated on the LP offers examples of the application of the “Pattern-Process-Service-Sustainability” framework. Future research using this framework should especially examine the integrated research of multiple processes, the cascades of ecosystem structure, function, services, and human-wellbeing, the feedback mechanisms of human and natural systems, and the data and models for sustainability.

Abstract. Topographic development via paraglacial slope failure
(PSF) represents a complex interplay between geological structure, climate,
and glacial denudation. Southeastern Tibet has experienced amongst the
highest rates of ice mass loss in High Mountain Asia in recent decades, but
few studies have focused on the implications of this mass loss on the
stability of paraglacial slopes. We used repeat satellite- and unpiloted aerial
vehicle (UAV)-derived
imagery between 1990 and 2020 as the basis for mapping PSFs from slopes
adjacent to Hailuogou Glacier (HLG), a 5 km long monsoon temperate valley
glacier in the Mt. Gongga region. We observed recent lowering of the glacier
tongue surface at rates of up to 0.88 m a−1 in the period 2000 to 2016,
whilst overall paraglacial bare ground area (PBGA) on glacier-adjacent
slopes increased from 0.31 ± 0.27 km2 in 1990 to
1.38 ± 0.06 km2 in 2020. Decadal PBGA expansion rates were
∼ 0.01 km2 a−1, 0.02 km2 a−1, and 0.08 km2 in the
periods 1990–2000, 2000–2011, and 2011–2020 respectively, indicating an
increasing rate of expansion of PBGA. Three types of PSFs, including
rockfalls, sediment-mantled slope slides, and headward gully erosion, were
mapped, with a total area of 0.75 ± 0.03 km2 in 2020. South-facing
valley slopes (true left of the glacier) exhibited more destabilization
(56 % of the total PSF area) than north-facing (true right) valley slopes
(44 % of the total PSF area). Deformation of sediment-mantled moraine
slopes (mean 1.65–2.63 ± 0.04 cm d−1) and an increase in
erosion activity in ice-marginal tributary valleys caused by a drop in local
base level (gully headward erosion rates are 0.76–3.39 cm d−1) have
occurred in tandem with recent glacier downwasting. We also observe
deformation of glacier ice, possibly driven by destabilization of lateral
moraine, as has been reported in other deglaciating mountain glacier
catchments. The formation, evolution, and future trajectory of PSFs at HLG
(as well as other monsoon-dominated deglaciating mountain areas) are related
to glacial history, including recent rapid downwasting leading to the
exposure of steep, unstable bedrock and moraine slopes, and climatic
conditions that promote slope instability, such as very high seasonal
precipitation and seasonal temperature fluctuations that are conducive to
freeze–thaw and ice segregation processes.

Abstract. In the East Asian monsoon region, winter extreme precipitation events occasionally occur and bring great social and economic losses. From December 2018 to February 2019, southeastern China experienced a record-breaking number of extreme precipitation events. In this study, we analyzed the variation in water vapor isotopes and their controlling factors during the extreme precipitation events in Nanjing, southeastern China. The results show that the variations in water vapor isotopes are closely linked to the change in moisture sources. Using a water vapor d-excess-weighted trajectory model, we identified the following five most important moisture source regions:
South China, the East China Sea, the South China Sea, the Bay of Bengal, and continental regions (northwestern China and Mongolia). Moreover, the variations in water vapor d excess during a precipitation event reflect rapid shifts in the moisture source regions. These results indicate that rapid shifts among multiple moisture sources are important conditions for sustaining wintertime extreme precipitation events over extended periods.
