Authors: Baram Shahar , Bar-Tal Asher , Gal Alon , Friedman Shmulik P. , Russo David
Published: April 2022

Abstract. Static chambers are commonly used to provide in-situ quantification of N2O fluxes. Despite their benefits, when left in the field, the physicochemical conditions inside the chamber's base may differ from the ambient, especially in drip-irrigated systems. This research aimed to study the effects of static chambers' bases on water and N-forms distribution and the impact it has on N2O measurements in drip irrigation. N2O emissions were measured in a drip-irrigated avocado orchard for two years, using bases with a dripper at their center (In) and bases installed adjacent to the dripper (adjacent). During the irrigation/fertigation season, the measured N2OIn fluxes were greater than the N2OAdjecent fluxes (0.82 ± 0.15 vs. 0.36 ± 0.05 ng cm-2 sec-1). In contrast, during the winter, when the orchard is not irrigated or fertilized, insignificant differences were observed between the measured N2OAdjecent and N2OIn fluxes. Three dimentional simulations of water flow and N-forms transport and transformations showed two opposing phenomena (a) increased water contents, N concentrations, and downward flushing when the dripper is placed inside the base, and (b) hampering of the lateral distribution of water and solutes into the most bio-active part of the soil inside the base when the base is placed adjacent to the dripper. It also showed that both "In" and "adjacent" practices underestimate the "true" cumulative flux from a dripper with no base by ~25 % and ~50 %, respectively. A nomogram in a non-dimensional form corresponding to all soil textures, emitter spacings and discharge rates, was developed to determine the optimal diameter of an equivalent cylindrical base to be used along a single dripline.

Abstract. The Millennium Drought lasted more than a decade, and is notable for causing persistent shifts in the relationship between rainfall and runoff in many south-east Australian catchments. Research to date has successfully characterised where and when shifts occurred and explored relationships with potential drivers, but a convincing physical explanation for observed changes in catchment behaviour is still lacking. Originating from a large multi-disciplinary workshop, this paper presents a range of possible process explanations of flow response, and then evaluates these hypotheses against available evidence. The hypotheses consider climatic forcing, vegetation, soil moisture dynamics, groundwater, and anthropogenic influence. The hypotheses are assessed against evidence both temporally (eg. why was the Millennium Drought different to previous droughts?) and spatially (eg. why did rainfall-runoff relationships shift in some catchments but not in others?). The results point to the unprecedented length of the drought as the primary climatic driver, paired with interrelated groundwater processes, including: declines in groundwater storage, reduced recharge associated with vadose zone expansion, and reduced connection between subsurface and surface water processes. Other causes include increased evaporative demand and interception of runoff by small private dams. Finally, we discuss the need for long-term field monitoring, particularly targeting internal catchment processes and subsurface dynamics. We recommend continued investment in understanding of hydrological shifts, particularly given their relevance to water planning under climate variability and change.

Published: April 2022

Abstract. Sea level rise and coastal erosion have inundated large areas of Arctic permafrost. Submergence by warmer and saline waters increases the rate of inundated permafrost thaw compared to sub-aerial thawing on land. Studying the contact between the unfrozen and frozen sediments below the seabed, also known as the ice-bearing permafrost table (IBPT), provides valuable information to understand the evolution of sub-aquatic permafrost, which is key to improving and understanding coastal erosion prediction models and potential greenhouse gas emissions. In this study, we use data from 2D electrical resistivity tomography (ERT) collected in the nearshore coastal zone of two Arctic regions that differ in their environmental conditions (e.g., seawater depth and resistivity) to image and study the subsea permafrost. The inversion of 2D ERT data sets is commonly performed using deterministic approaches that favor smoothed solutions, which are typically interpreted using a user-specified resistivity threshold to identify the IBPT position. In contrast, to target the IBPT position directly during inversion, we use a layer-based model parameterization and a global optimization approach to invert our ERT data. This approach results in ensembles of layered 2D model solutions, which we use to identify the IBPT and estimate the resistivity of the unfrozen and frozen sediments, including estimates of uncertainties. Additionally, we globally invert 1D synthetic resistivity data and perform sensitivity analyses to study, in a simpler way, the correlations and influences of our model parameters. The set of methods provided in this study may help to further exploit ERT data collected in such permafrost environments as well as for the design of future field experiments.
Changing the Narrative, Again
Authors: Schuurman Anton
Published: April 2022

In this article I argue that the development of postmodernism and the return of the narrative in the1970s did not just happen for internal scientific reasons but were a reaction to the societal developments and theories at the time. To this end I use the contemporary criticism concerning postmodernism by Beck and Giddens. In the second part I highlight three monographs to argue that social science history in recent decades also renewed itself against this background, thus helping us to understand our contemporary world in which questions of transitions and transformations are central. They use history to inform and diagnose our current situation, which they therefore need to understand as an ongoing process, though not necessarily a continuing one.

Published: April 2022

The aim of this study is to establish the functional relationships between different groups of factors of production and the stability of the lining of small-volume converters. At the stage of development of world metallurgy, the oxygen-converter process is the most popular way of producing structural steel. Its main difference is high productivity, which is determined by the duration of maintenance-free periods of smelting units. Under the current conditions, it is possible to increase productivity and reduce the cost of steel production in converters by increasing the stability of refractory linings. Thus it is relevant and necessary to assess the factors influencing the stability of the lining and the search for rational technological conditions for its operation. A statistical analysis over a five-year period of the work of two 50-ton converters with top blowing, which was lined with periclase carbon heat-treated refractories, was conducted. It was established that the dependences of the lining stability on the consumption indicators of charge materials are extreme: the consumption of hot metal at the level of 920-930 kg/t of steel corresponds to the lowest indicators of the lining stability; scrap consumption at the level of 200 -
220 kg/t of steel and lime consumption at the level of 70-75 kg/t of steel correspond to the best working conditions of the lining. Regarding the chemical composition of processed hot metal, the best working conditions of the lining correspond to the content of silicon in it at the level of 0.80-0.85% of the mass and manganese - 0.50-0.60% of the mass.
Researches shown that in order to more accurately interpret the impact of certain factors on the stability of the lining of oxygen converters, it is necessary to group factors by organizational and production characteristics and conduct a detailed analysis in each of the groups. According to the results of correlation and regression analysis, the equation was obtained, which allows to predict the stability of the lining of converters with a capacity of 50 tons. The resulting equation can be used in industrial conditions to predict the stability of the lining.

Published: April 2022

The purpose of the work is to reveal the essence of the proposed new approach to describe the patterns of distribution of elements between the metal and slag phases, the basis for the development of which was the created information and intellectual resources of the knowledge base "Metallurgy" developed in Iron and Steel Institute of Z.I.Nekrasov of the NAS of Ukraine. The information component is a database continuously updated with modern data on the properties of metallurgical melts "Metal", "Slag", "Ferroalloys" and "Metal-Slag-Gas" and containing the results of our own and industrial experimental studies of the properties of metallurgical melts and literary searches (articles, patents, inventions, scientific developments, monographs). As a scientific basis for describing the processes of interactions between phases, the work uses the original concept of directed chemical bonding, as well as the experience accumulated in the department of physicochemical problems of metallurgical processes in creating information and analytical systems for forecasting and controlling the processes of iron and steel smelting. The starting points laid down in the concept of directed chemical bonding are its core and consider melts as chemically unified systems, and simply not mechanical mixtures of components. This approach allows to describe in more detail the physicochemical interactions in a multiphase metallic medium. The main difference between the proposed approach and the existing ones consists in taking into account interatomic bonds in the interaction of metal and slag melts, complex ratios of their physicochemical and thermophysical properties, as well as significant technological parameters during out-of-furnace treatment in a ladle-furnace unit. Adequate mathematical models (R2≥0,9) have been developed, which allow to quantify the efficiency of assimilation and distribution of additives that determine the technological purposefulness of the processing of an intermediate product and determine the selection from these positions of rational compositions of alloying and refining components within the domestic raw material base.

The aim of the work is to study modern ways to increase the operational reliability of the furnace and hearth of blast furnaces, which largely determine the duration of the blast furnace campaign. The article analyzes the ways to increase the stability of the furnace and hearth, presents the results of the analysis of thermal work and ignition of the lining of metal receivers of blast furnaces of different designs. The modern directions of construction of the metal receiver of blast furnaces are determined. It is shown that the modern methodology of construction of blast furnace furnaces develops two main directions: the use of a coordinated combination of refractory materials with a cooling system; use of a combination of wear-resistant materials based on carbon and ceramics. However, even the improvement of the design and cooling system of the metal receiver does not allow to fully increase the duration of the campaign. To assess the service life of the furnace, it is necessary to provide regular automated control of the ignition of the furnace lining and hearth. In Ukraine, during the renovation of blast furnaces, the design of metal receivers with the use of "ceramic glass" was preferred. To date, the system of monitoring the thermal work and ignition of the furnace has been implemented in 10 blast furnaces using the automatic control system "Horn" developed by the HMI NASU. The implementation of continuous control over the ignition of the furnace in blast furnaces allowed us to assess the effect of the use of ceramic cups. The value of heat losses of the furnace and the cost of coke for their compensation are estimated. Methods and models for determining the thermal state and wear of the metal receiver lining based on a combination of calorimetric and thermometric control methods have been developed. Comparison of heat losses of the metal receiver in the cooling system of blast furnaces allows to quantify the thermal performance of controlled areas and the furnace as a whole. It is shown that the specific value of heat loss of the metal receiver per unit volume of the blast furnace can serve as an integral parameter. It is established that the value of specific heat losses per unit volume of the blast furnace with a ceramic cup is ~ 0.4-0.7 kW/m3, which is much less than blast furnaces without it (~ 0.9-1.1 kW/m3). Ceramic glass saves coke about 1 kg/t of cast iron.

The article presents the results of using a drug with a controlled long-term release of a substance in a bolus form, which was administered orally to lactating cows with a predisposition to the development of metabolic disorders - first of all, the development of ketosis. As a result of the work, it was determined that in the experimental group of animals there was an unreliable increase in the concentration of total protein in the blood serum, while it should be noted that the phenomenon of the % ratio of albumin and globulins was impaired in animals of both groups. Also, in the experimental group of cows, the concentration of urea increased by 22%, which indicates the activation of protein metabolism, the cholesterol level in cows of both experimental groups increased. An analysis of the changes in lipids showed that the cholesterol concentration in the control group of cows by the 30th day of the experiment became 15% higher, and in the experimental group of animals - 27.9% higher, while the intergroup difference between them was 12.7%. The levels of triglycerides in animals of both groups were approximately the same and did not have significant differences, although their concentration slightly increased. The data obtained may indicate that under the action of boluses with prolonged release of components, there is a faster activation of metabolic processes in the body of cows in the postpartum period.

Since COVID-19 became a pandemic, the global economy has been dramatically affected. Not just that, the consumer behavior in the retail market has also changed. This paper aims to examine the effect of the coronavirus crisis on consumer behavior in retail services. The paper will focus on retail banking services, especially the Jordanian banking sector. The goal of the study was achieved by conducting a survey among Jordanian consumers in the retail banking sector, which was done using questionnaires, a sample of 240 retail customers from 14 valid participants. The paper brings new insight into how the pandemic affected retail banking services and proves the acceptance of online and banking in the conceptual model. The results show that the variables around attitudes toward the internet and mobile banking were directly and positively affected by the variables related to the perception of the pandemic's impact on the consumer's lifestyle. Other variables such as the safety of using online and mobile banking services and phones also contributed to this rise in a positive attitude. The Trust in Mobile and internet banking has several administrative and social implications, which were also discussed. Because new consumption behavior models are being developed, mobile and internet services could prevail even after the later stages of the epidemic. Initiatives to provide online educational programs, especially financial courses, should be intensified by the banks in Jordan to enable their customers to be familiar with the use of the banks' online banking services. They should enhance their communication with their customers and offer new products and services while also showing flexibility while negotiating to refinance and loaning terms.

This paper investigates how customs officials perceive the implementation of e-customs will influence business performance in Vietnam, a developing country with a lower technological environment. A survey of customs officials was conducted, and data were analyzed by structural equation modelling. The outcomes discover two significant enablers related to relative advantages and the new exploring factor Culture while Finance & Human Resources and Legislation as the inhibitors. Additionally, the study also emphasized that e-customs implementation had a positive influence on firm performance in Vietnam. In addition, the study provides different viewpoints of cultural dimensions in case study of applying e-customs in Vietnam in comparison with previous studies. Culture with attributions related to uncertain acceptance and individualism encourage innovation in other literature reviews, however, the study indicates uncertainty avoidance and collectivism as Vietnam also promotes e-customs deployment. Vietnam with high power distance and short-term orientation became old themes. This emerging country switched to low distance and long-term orientation in terms of e-customs innovation. In contrast to previous studies related to constraints from technology in emerging economies, technological factors are not an obstacle for Vietnam. Furthermore, previous literature reviews inflected legislation and regulations of government as one of the limitations that should be examined in further and this research carried-out this investigation in one of emerging economies. The results of the paper support policy makers who can have essential solutions to enhance e-customs implementation as well as enterprises’ managers set-up strategy to adapt with the modernization environment.

As part of their corporate social responsibility (CSR) and sustainable products, many big players in the industry have now reduced plastic through the design, manufacturing and packaging of products and their ultimate disposal. This paper investigates the direct and indirect relationships between awareness, trust, and brand preference on purchase intention in green marketing. Based on a review of the literature, a series of hypotheses are derived and tested using regression analysis. The research employs an online survey-based method to test a theoretically grounded set of proposed hypotheses. The data were collected from 348 young adults living in Jakarta, Indonesia. The results show that green awareness does not influence purchase intention directly. On the other hand, the indirect effect of green awareness through green brand preference on purchase intention was greater compared with the indirect effect through green trust. Therefore, this study draws attention to the importance of green brand preference and green trust on purchase intention. Given that the consumption of organic products has the potential to elicit awareness, trust, and preference of eco-friendly consumers, these findings have significant management implications for corporate managers when considering the production of organic commodities.

Published: April 2022

This study investigates the application of the technology acceptance model (TAM) on the digital payment using social media platforms with the extended inclusion of perceived ease of use, perceived security, perceived usefulness, and trust in enhancing consumer behavioral intention. This work has surveyed 250 consumer films on the digital social media platform. Data collection used a questionnaire designed with a five-point Likert scale. The questionnaire was created using a Google Form, and questionnaire distribution was performed by sending the link through social media to the respondents. As many as 300 questionnaires were distributed, and 258 questionnaires were considered valid for further analysis. Data analysis used smartPLS software version 3.0. The result revealed that nine hypotheses were empirically supported while the others two were not supported. Perceived security directly affects trust and consumer behavioral intention. Perceived ease of use directly affects perceived usefulness and consumer behavioral intention. Perceived security indirectly influences consumer behavioral intention through trust and perceived usefulness. Furthermore, perceived usefulness directly affects trust and consumer behavioral intention. Besides, trust directly affects consumer behavioral intentions. Perceived ease of use indirectly affects behavioral intention through perceived usefulness. Moreover, perceived security affects consumer behavioral intentions indirectly through trust. Perceived ease of use influences perceived usefulness. However, perceived usefulness did not indirectly influence behavioral intention through trust. Finally, perceived ease of use did not affect consumer behavioral intention through perceived usefulness and trust. These findings extended the application of the technology acceptance model in using digital payment platforms in Indonesia. These findings reinforced current research on user adoption of new technology. Furthermore, this result provides a managerial implication for digital payment platforms providers to improve consumer behavioral intentions.

Published: April 2022

Indonesia is a country dominated by rural areas. Addressing rural poverty is a priority of the Indonesian government work program and an effort to achieve the Sustainable Development Goals (SDGs). One of the actual programs dealing with poverty is a digital village which is implemented in a smart village ecosystem. Since 2018, Indonesia has initiated various pilots of smart village projects. The success of a smart village is closely related to citizen science. The purpose of this research was to build a citizen science prospect model for a smart economy in a smart village ecosystem using Structural Equation Model – Partial Least Square (SEM-PLS) approach. This study proposes a novelty of measuring villagers' readiness to build a smart economy in a smart village ecosystem based on the strength of community support. We propose an assessment of the prospect of developing a smart economy in a smart village through the citizen science level that integrates exogenous variables of community support for the environment, citizen character, empowerment, entrepreneurship, innovation, and the smart economy. The citizen science model towards a smart economy showed a high level of predictive relevance, which was 87,2%. The citizen science model towards a smart economy can also explain empirical data with a GoF value of 0,488. This research showed that the indicators of Information Communication Technology (ICT), ICT literacy, access to education and research and development (R & D) facilitation, motivation for smart villages, and innovation in villages were driven by family participation. The collaboration with the private sector, local government, and communities drive the village's smart economy. The SEM PLS approach has not been widely used in research on the smart village component, especially the relationship between citizen science and the smart economy. Therefore, this research can fill the gap in smart village research, which is still dominated by a descriptive approach.

Virtual reality (VR) is a new technology that has applications in a variety of sectors, including medical, education, gaming, psychology, and sociology. The application of VR in education is intriguing and warrants further examination, but research on the subject is currently restricted. VR can benefit education by allowing students to participate in memorable and engaging experiences that they would not otherwise be able to have. Traditional approaches are still used to teach students, which is an essential element of the curriculum for those who want to conceive problem-solving. As a result, there is a scarcity of study on VR deployment. In this paper, we investigated the factors affecting the adoption of VR in higher educational institutes. To this end, we extended the technology Acceptance Model (TAM) with four additional factors and formulated a set of hypotheses. The hypotheses are then evaluated using a dataset collected from 503 Jordanian students. The result shows that the factors perceived facilitating condition, perceived effort expectancy, and perceived compatibility significantly affected the intention to use VR systems and tools for educational purposes. We believe that this study will help decision makers to build sustainable learning and educational systems in Jordan universities.

Today, the use of technology has made education more enjoyable. Vocabulary retention becomes a challenging task for both teachers and learners. They may learn the vocabulary but may not retain it. Yet, the use of web-based games may assist them in maintaining words known for short and long-term retention. The current study was conducted to identify students' abilities in retaining words learned after they were assigned to play a web-based vocabulary learning game, namely OnVac. Both short and long-term retention were measured after they were required to play the game as a treatment. Also, the study investigated students' perceptions about the system operation of OnVac. The use of quantitative research design, particularly quasi-experimental research and survey showed gains in vocabulary retention among students for short and long-term retention. The study also found that OnVac can support vocabulary learning among students in their learning of the specialized vocabulary. In terms of the system operation, the participants reported that the tool could assist them in learning engineering and technology words as it was convenient to use. The study provided implications to the teaching pedagogy in that teachers need to be wise and analytical in developing the online game to assist learners in learning English specialized vocabulary.

This paper empirically identifies the predictors influencing the use of promo code in Jordan. This research extended TAM and TBP models with perceived enjoyment and brand image in the context of digital shopping features. The study utilized 379 surveys distributed in Jordan and analyzed the data using SEM. Findings of this study confirmed the proposed model, where brand image, perceived enjoyment, perceived behavior control and social influence significantly predict customers behavioral intention to use promo code with an R2 = 59%. The model of this study also supported the role of perceived ease of use and social influence in predicting brand image. Discussion and conclusion are depicted at the end of this paper.

We present a case of arteriovenous malformation with aneurysmatic dilatation of the drainage vein, presenting with obstructive hydrocephalus located in the tectum. A 59-year-old female patient was taken to the emergency department after complaining for 8 days of increasingly worsening headache, gait disturbance, sleepiness, blurred vision, and double vision, as well as gush vomiting. The patient indicated that he had been experiencing from intermittent headaches for almost a year. On examination, there was an ataxic walk, bilateral papilledema, and slight cognitive impairment. CT, MRI and CTA imaging tests were used for the diagnosis, respectively (Figures 1-3). CT scans of the brain revealed triventricular hydrocephalus and a dense space occupying lesion thought to produce aqueductal stenosis in the tectal region of the mesencephalon (Figure 1). Following that, the patient had brain MRI and CTA imaging. This dense lesion in the tectum was found to be a vascular structure connected to the adjacent arteriovenous capillary network and the vein of galena (Figure 2,3). In the differential diagnosis, arteriovenous malformation with aneurysmatic dilatation in the drainage vein was considered primarily.
