The present study intends to improve the robustness of a flood susceptibility (FS) model with a small number of parameters in data-scarce areas, such as northwest Bangladesh, by employing machine learning-based sensitivity analysis and an analytical hierarchy process (AHP). In this study, the nine most relevant flood elements (such as distance from the river, rainfall, and drainage density) were chosen as flood conditioning variables for modeling. The FS model was produced using AHP technique. We used an empirical and binormal receiver operating characteristic (ROC) curves for validating the models. We performed Sensitivity analyses using a random forest (RF)-based mean Gini decline (MGD), mean decrease accuracy (MDA), and information gain ratio to find out the sensitive flood conditioning variables. After performing sensitivity analysis, the least sensitivity variables were eliminated. We re-ran the model with the rest of the parameters to enhance the model’s performance. Based on previous studies and the AHP weighting approach, the general soil type, rainfall, distance from river/canal (Dr), and land use/land cover (LULC) had higher factor weights of 0.22, 0.21, 0.19, and 0.15, respectively. The FS model without sensitivity and with sensitivity performed well in the present study. According to the RF-based sensitivity and information gain ratio, the most sensitive factors were rainfall, soil type, slope, and elevation, while curvature and drainage density were less sensitive parameters, which were excluded in re-running the FS model with just vital parameters. Using empirical and binormal ROC curves, the new FS model yields higher AUCs of 0.835 and 0.822, respectively. It is discovered that the predicted model’s robustness may be maintained or increased by removing less relevant factors. This study will aid decision-makers in developing flood management plans for the examined region.

Authors: Bortone Imma , Sakar Hacer , Soares Ana
Published: March 2022

Green technologies (Green-Tech) are solutions aiming to mitigate or reverse the effects of human activity on the environment. The United Kingdom (UK) government established a Ten-Point Plan and over GBP 5 billion to support Green-Tech to lay the foundations for a green industrial revolution and reduce emissions by 180 million tons of carbon dioxide equivalent (CO2e) by 2032. Households and buildings contribute around 40% of the UK’s total GHG emissions, which implies that key actions are needed in all areas around the building sector (Point 7). This study provides an overview and analysis of the existing regulation and standards in the UK building/household sector, to understand the current state-of-the-art and identify gaps preventing Green-Tech wider implementation and use. Discrepancies in regulation and standards were identified. Given that households bring together and adhere to numerous standards and regulations, the analysis highlighted that it is critical to formulate relevant actions starting from the individuals with engagement and information. Complete and clear guidelines addressing environmental awareness, the performance and economical convenience of Green-Tech implementation and related regulations, are required to come to a consensus on the best way to move forward to achieve sustainability and NET-ZERO targets.
Leveraging UAV Capabilities for Vehicle Tracking and Collision Risk Assessment at Road Intersections

Published: March 2022

Transportation agencies continue to pursue crash reduction. Initiatives include the design of safer facilities, promotion of safe behaviors, and assessments of collision risk as a precursor to the identification of proactive countermeasures. Collision risk assessment includes reliable prediction of vehicle trajectories. Unfortunately, in using traditional tracking equipment, such prediction can be impaired by occlusion. It has been suggested in recent literature that unmanned aerial vehicles (UAVs) can be deployed to address this issue successfully, given their wide visual field and movement flexibility. This paper presents a methodology that integrates UAVs to track the movement of road users and to assess potential collisions at intersections. The proposed methodology includes an existing deep-learning-based algorithm to identify road users, extract trajectories, and calculate collision risk. The methodology was applied using a case study, and the results show that the methodology can provide beneficial information for the purpose of measuring and analyzing the infrastructure performance. Based on vehicle movements it observes, the UAV can communicate its collision risk to each vehicle so that the vehicle can undertake proactive driving decisions. Finally, the proposed framework can serve as a valuable tool for urban road agencies to develop measures to reduce crash risks.

Authors: Souza Juliana Mio de , Morgado Paulo , Costa Eduarda Marques da , Vianna Luiz Fernando de Novaes
Published: March 2022

The simulation and analysis of future land use and land cover—LULC scenarios using artificial neural networks (ANN)—has been applied in the last 25 years, producing information for environmental and territorial policy making and implementation. LULC changes have impacts on many levels, e.g., climate change, biodiversity and ecosystem services, soil quality, which, in turn, have implications for the landscape. Therefore, it is fundamental that planning is informed by scientific evidence. The objective of this work was to develop a geographic model to identify the main patterns of LULC transitions between the years 2000 and 2018, to simulate a baseline scenario for the year 2036, and to assess the effectiveness of the Chapecó River ecological corridor (an area created by State Decree No. 2.957/2010), regarding the recovery and conservation of forest remnants and natural fields. The results indicate that the forest remnants have tended to recover their area, systematically replacing silviculture areas. However, natural fields (grassland) are expected to disappear in the near future if proper measures are not taken to protect this ecosystem. If the current agricultural advance pattern is maintained, only 0.5% of natural fields will remain in the ecological corridor by 2036. This LULC trend exposes the low effectiveness of the ecological corridor (EC) in protecting and restoring this vital ecosystem.

Published: March 2022

Events, such as the COVID-19 pandemic, that rapidly impact global communication and travel have significant consequences for the tourism industry, which is one of the pillars of global development. We assess the impacts of the COVID-19 crisis on the Colca y Volcanes de Andagua UNESCO Global Geopark in Peru. The Colca y Volcanes de Andagua Geopark was established immediately prior to the pandemic in October 2019. The instability of the government in Peru during the pandemic and the difficult living conditions in the high Andes, such as the lack of drinking water, cleaning agents, medical care, and the high levels of poverty, particularly in the geopark region, has contributed to the significantly high COVID-19 infection rates. In addition, detrimental impacts faced by the local community are a direct result of a reduction in travellers to the area due to legislative restrictions, which have had negative consequences on the local tourism industry. There is an urgent need for the recovery of the local tourism industry to prevent the permanent closure of tourism facilities and to minimise poverty rates.

Authors: Powers Samantha Rae , Gazica Michele W. , Myers Karen K.
Published: March 2022

This study examines the role of work-related emotional communication in promoting the well-being and sustainability of professionals working for professional service firms (PSFs), which depend upon the well-being of their professionals for their own organizational sustainability. Using survey data from 1465 attorneys, a structural equation model was tested including key work-related emotional communication variables as mediators between a dichotomous variable of professional seniority and three dimensions of burnout. Results showed that more experienced attorneys’ reliance on automatic regulation over surface acting has a significant effect on reported burnout. There is no difference based on professional seniority in use of deep acting or communicative responsiveness. We conclude with a discussion of the findings and theoretical and practical implications, as well as provide suggestions for future research.
The Productive Orientation of Rural Extensionists in the Regions of Mexico: A Key Element for Agroecological Transition
Authors: Gallardo-López Felipe , Landini Fernando , Hernández-Chontal Mario Alejandro
Published: March 2022

Considering the agroclimatic and social diversity of Mexico, this paper starts by recognizing the potential of rural extensionists within a policy framework of agroecological transition in the country. This paper identifies the types of productive positioning (agroecological vs. conventional) of rural extensionists located across the diverse states and socioeconomic regions of Mexico. This data is intended to outline particular features for the differentiation and targeting of regional strategies to train extensionists according to their regional context. We analyzed 1448 questionnaires gathered in 2019 via the online platform SurveyMonkey from rural extensionists enrolled in the Mexican Rural Extension System (SERMexicano). The results revealed that extensionists mainly identified themselves with the agroecological model. However, a significant proportion across states and regions still associated themselves with the conventional model. Three types of trends were recognized in relation to the positioning of extensionists, namely agroecological, towards neutrality, and contrasting. According to the socioeconomic regions where extensionists are located, diverse inter- and intraregional nuances among these positionings were also identified. Finally, we conclude by emphasizing the need for this heterogeneity to be considered in order to design and implement programs aimed at transitioning and expanding agroecology in Mexico.
An Analysis of the Development of Modular Building Design Elements to Improve Thermal Performance of a Representative High Rise Residential Estate in the Coastline City of Famagusta, Cyprus
Authors: Altan Hasim , Ozarisoy Bertug
Published: March 2022

Passive design strategies can reduce heating and cooling demands with integration of more efficient building systems as well as the potential to integrate modular off-site construction technology and its technical systems to offset overall energy consumption. This study evaluates the energy performance of the nationally representative post-war social housing estate in the southeastern Mediterranean island of Cyprus where the weather is subtropical (Csa) and partly semi-arid (Bsh). This study employed a mixed methods research design approach which was based on a thorough field study that consisted of a questionnaire survey conducted with residents of the social housing estate in the hottest summer month of August, to explore the occupants’ thermal sensation votes (TSVs), their habitual adaptive behaviour, and home energy performance concurrently. On-site environmental monitoring was performed, and in-situ measurements of each occupied space were recorded to identify ‘neutral’ adaptive thermal comfort. The selected representative high-rise residential development was modelled using Integrated Environmental Solutions’ Virtual Environment (IES-VE) software, where extensive dynamic thermal simulations have been produced to assess existing energy performance and energy effectiveness of retrofitting strategies. The results demonstrated that a moderate–strong relationship was found between orientation and reasons for thermal discomfort (χ2 = 49,327, p < 0.001, Cramer’s V = 0.405). Individual levels of thermal comfort were not limited to household socio-demographic characteristics, however; environmental factors were also determinants in the development of adaptive thermal-comfort theory. Furthermore, the occupants’ TSVs indicated that in a southeastern Mediterranean climate, 28.5 °C is considered a neutral temperature, and the upper limit of the indoor-air thermal-comfort range is 31.5 °C.

Published: March 2022

Soil erosion causes land degradation which negatively impacts not only natural resources but also livelihoods of people due to low agricultural productivity. Cambodia is prone to soil erosion due to poor agricultural practices. In this research we use Battambang province as a case study to quantify impact of land use and land cover change (LULC) on soil erosion. This study assessed the impact from LULC changes to soil erosion. LULC change maps were analyzed based on Landsat satellite imagery of 1998, 2008, and 2018, computed in QGIS 6.2.9, while the soil erosion loss was estimated by the integration of remote sensing, GIS tools, and Revised Universal Soil Loss Equation (RUSLE) model. The results showed that the area of agricultural land of Battambang province significantly increased from 44.50% in 1998 to 61.11% in 2008 and 68.40% in 2018. The forest cover significantly decreased from 29.82% in 1998 to 6.18% in 2018. Various soil erosion factors were estimated using LULC and slope. Based on that, the mean soil loss was 2.92 t/ha.yr in 1998, 4.20 t/ha.yr in 2008, and 4.98 t/ha.yr in 2018. Whereas the total annual soil loss was 3.49 million tons in 1998, 5.03 million tons in 2008, and 5.93 million tons in 2018. The annual soil loss at the agricultural land dramatically increased from 190,9347.9 tons (54%) in 1998 to 3,543,659 tons (70.43%) in 2008 and to 4,267,439 tons (71.91%) in 2018 due to agricultural land expansion and agricultural practices. These losses were directly correlated with LULC, especially agricultural land expansion and forest cover decline. Our results highlight the need to develop appropriate land use and crop management practices to decrease land degradation and soil erosion. These data are useful to bring about public awareness of land degradation and alert local citizens, researchers, policy makers, and actors towards land rehabilitation to bring the area of land back to a state which is safe for increasing biodiversity and agricultural productivity. Measures to reduce or prevent soil erosion and the use of conservation agriculture practices, along with water and soil conservation, management, agroforestry practices, vegetation cover restoration, the creation of slope terraces, and the use of direct sowing mulch-based cropping systems should be considered.

Authors: Akkaya Bulent , Bagieńska Anna
Published: March 2022

The need for organizations to adapt to constant change means the challenges of implementing an agile strategy. Therefore, the purpose of the study is to analyze the role of agile women leadership and team effectiveness by looking into the mediating effect of interpersonal trust based on a cross-sectional quantitative study with a sample of 269 employees from Poland and Turkey. Questionnaires were distributed to individuals in companies having women leaders or managers. The three questionnaires required the respondents to answer questions regarding the perception of agile leadership, trust and team effectiveness. By using SPSS, demographics, descriptive statistics and tests of normality were determined. Smart PLS version 3.0 was used for confirmatory factor analysis, internal accuracy and validity estimates, hypothesis checking and mediation testing. Results of PLS-SEM indicated interpersonal trust has a full mediation role between agile women leadership in shaping team effectiveness. The population of this study are working for organizations of just two countries; hence, the generalizability of the findings to other settings is unknown. Our findings contribute to the literature on women agile leadership and team effectiveness by demonstrating how the growth in trust to managers contributes to the emergence of team effectiveness and the agile leadership trend over time. This study will therefore contribute to the understanding of organized teams’ effectiveness in the perspective of agile women leadership and trust of supervisors.
Sustainability and the Digital Transition: A Literature Review
Authors: Rosário Albérico , Dias Joana
Published: March 2022

The digital transition processes have demonstrated an enormous capacity to develop and implement sustainable solutions, which allow solving several problems such as poverty, high rates of species extinction and lack of equal opportunity. However, little attention is paid to the connection between the digital transition and sustainability. Thus, a systematic bibliometric literature review was developed to fill this knowledge gap and demonstrate the potential contributions of the digital transition to environmental, economic, and social sustainability aspects. In environmental sustainability, the digital transition involves the application of technologies such as Artificial Intelligence (AI), big data analytics, Internet of Things (IoT), and mobile technologies that are used to develop and implement sustainability solutions in areas such as sustainable urban development, sustainable production, and pollution control. In economic sustainability, emerging digital technologies can drive transformation into a more sustainable circular economy, the digital sharing economy, and establish sustainable manufacturing and infrastructure design. In the digital transition to social sustainability, the studies analyzed demonstrate the need for multidimensional policy perspectives to address the current digital divide. For effective management of the digital transition that achieves sustainability goals, the study discusses alternative approaches that include innovation through experimentation and dynamic and sustainable advantages achievable through temporary benefits.
Study on the Effect of Amorphous Silica from Waste Granite Powder on the Strength Development of Cement-Treated Clay for Soft Ground Improvement
Authors: Nakayenga Joyce , Inui Mutsuko , Hata Toshiro
Published: March 2022

Granite powder (stone powder), a waste product generated from stone quarries, is increasingly being reused in cement-treated clays. The particle size of stone powders affects the cement-clay reaction by either increasing or reducing the unconfined compressive strength (UCS). This study investigated this phenomenon by separating stone powder from the same batch at the quarry into five particle sizes (A, B, C, D and E: 106–75 µm, 40–75 µm, 20–40 µm, <20 µm and 106–<1 µm, respectively). Flow value, fall cone, UCS and thermogravimetry-differential thermal analysis (TG-DTA), X-ray fluorescence, electrical conductivity and NaOH digestion tests were conducted. It was discovered that stone powder had an amorphization rate of up to 1.45% (14.5 mg/g of amorphous silica); hence, it was pozzolanic. However, the amorphousness varied with the particle size of the material in the order of D > E > C > B > A, which translated into UCS variation in the same order. Stone powders D and E played two roles in UCS development, i.e., nucleation of cementitious products and reaction with Ca(OH)2 to increase the UCS higher than the control sample. Linear regression equations determined the minimum concentration of amorphous silica for a UCS increment as 9.4 mg/g.

Published: March 2022

The COVID-19 pandemic has caused educators around the world to access online-learning systems. Applying the online system involves challenges, such as the students’ need to cope with changes in their learning process, where they must develop capabilities to manage their learning more independently. Self-Regulated Learning (SRL) is an approach considered to help us understand students’ ability to manage their learning strategies and achieve improved performance. This paper aims to investigate the SRL of Indonesian students in underdeveloped areas when using a learning management system (LMS), namely SPADA, initiated by the Indonesian government. This study employed the clickstream data (CSD) of SPADA to examine students’ SRL within the first nine months of its implementation. We also analyzed the correlation of certain activities in SPADA with the students’ SRL results. The findings suggest some positive indications of SPADA implementation, particularly in promoting the students’ SRL, either students in general or in the underdeveloped areas. Some improvements indeed still need to be made on the system, including in improving the platform architecture to gain a better measurement method on students’ SRL.
The Principle of Maximum Entropy and the Distribution of Mass in Galaxies
Authors: Sánchez Almeida Jorge
Published: March 2022

We do not have a final answer to the question of why galaxies choose a particular internal mass distribution. Here we examine whether the distribution is set by thermodynamic equilibrium (TE). Traditionally, TE is discarded for a number of reasons including the inefficiency of two-body collisions to thermalize the mass distribution in a Hubble time, and the fact that the mass distribution maximizing the classical Boltzmann–Gibbs entropy is unphysical. These arguments are questionable. In particular, when the Tsallis entropy that describes self-gravitating systems is used to define TE, the mass distributions that result (i.e., the polytropes) are physically sensible. This work spells out this and other arguments for TE and presents the polytropes and their properties. It puts forward empirical evidence for the mass distribution observed in galaxies to be consistent with polytropes. It compares polytropes with Sérsic functions and it shows how the DM halos resulting from cosmological numerical simulations become polytropes when efficient collisions are allowed. It also discusses pathways to thermalization bypassing two-body collisions. It finally outlines future developments including deciphering whether or not DM particles collide efficiently.
A Matrix Model of Four-Dimensional Noncommutative Gravity
Authors: Manolakos George , Manousselis Pantelis , Roumelioti Danai , Stefas Stelios , Zoupanos George
Published: March 2022

In this review, we revisit our latest works regarding the description of the gravitational interaction on noncommutative spaces as matrix models. Specifically, inspired by the gauge-theoretic approach of (ordinary) gravity, we make use of the suggested methodology, modified appropriately for the noncommutative framework, of the well-established formulation of gauge theories on them. Making use of a covariant four-dimensional fuzzy space, we formulate the gauge theory with an extended gauge group due to noncommutativity. In turn, in order to decrease the amount of symmetry we employ a symmetry breaking and result with an action which describes a theory that is a minimal noncommutative extension of the original.
Technological Novelties of Ground-Based Very High Energy Gamma-Ray Astrophysics with the Imaging Atmospheric Cherenkov Telescopes
Authors: Mirzoyan Razmik
Published: March 2022

In the past three decades, the ground-based technique of imaging atmospheric Cherenkov telescopes has established itself as a powerful discipline in science. Approximately 250 sources of very high gamma rays of both galactic and extra-galactic origin have been discovered largely due to this technique. The study of these sources is providing clues to many basic questions in astrophysics, astro-particle physics, physics of cosmic rays and cosmology. The currently operational generation of telescopes offer a solid performance. Further improvements of this technique led to the next-generation large instrument known as the Cherenkov Telescope Array. In its final configuration, the sensitivity of CTA will be several times higher than that of the currently best instruments VERITAS, H.E.S.S., and MAGIC. This article is devoted to outlining the technological developments that shaped this technique and led to today’s success.

Published: March 2022

Porcine circovirus-like virus P1 can infect many kinds of animals and mainly causes postweaning multisystemic wasting syndrome. In China, the genetic diversity, variation, and evolutionary processes of this virus have not been described yet. To improve our knowledge of its genetic diversity, evolution, and gene flow, we performed a bioinformatics analysis using the available nucleotide sequences of the P1 virus; among them, 12 nucleotide sequences were from ten pig farms in Jiangsu Province in this epidemiological survey, and 84 sequences were downloaded from GenBank. The P1 sequences showed a rich composition of AT nucleotides. Analyses of the complete genomic sequences were polymorphic and revealed high haplotype (gene) diversity and nucleotide diversity. A phylogenetic analysis based on the NJ method showed that all P1 virus sequences formed two distinct groups: A and B. High genetic differentiation was observed between strains from groups A and B. The codon usage pattern of P1 was affected by dinucleotide compositions. Dinucleotide UU/CC was overrepresented, and dinucleotide CG was underrepresented. The mean evolutionary rate of the P1 virus was estimated to be 3.64 × 10−4 nucleotide substitutions per site per year (subs/site/year). The neutrality tests showed negative values. The purifying selection and recombination events may play a major driving role in generating the genetic diversity of the P1 population. The information from this research may be helpful to obtain new insights into the evolution of P1.

Meat and bone meal (MBM) is one animal by-product used in pets. This study purposed to provide information on MBM including either coarsely (MBMc) or finely (MBMf) ground with regard to diet digestibility and fecal characteristics in dogs. Three different levels of MBM (6%, 12% and 24%) of each grinding form (MBM6, MBM12 and MBM24) were added to a basic diet. Six Beagle dogs (body weight 16.7 kg ± 0.42) participated in a Latin Square experiment. Each trial began with the animals adapting to the food for a five-day period, followed by five days of fecal collection. The feed particle size had no effect on the apparent digestibility of organic matter, crude protein and crude fat. The fecal score was significantly affected by the particle size × level interaction among treatments (p < 0.0001). It was noted that the different particle sizes or levels of MBM as main effects had no significant effect on the fecal fatty acid concentrations. These findings suggest that using coarse or fine grinding even including MBM up to 24% in dog diets does not affect the apparent digestibility of protein nor fecal quality negatively in our experimental study.
Farmers’ Participatory Alternate Wetting and Drying Irrigation Method Reduces Greenhouse Gas Emission and Improves Water Productivity and Paddy Yield in Bangladesh
Authors: Hossain Mohammad Mobarak , Islam Mohammad Rafiqul
Published: March 2022

In dry season paddy farming, the alternate wetting and drying (AWD) irrigation has the potential to improve water productivity and paddy production and decrease greenhouse gas (GHG), such as methane (CH4) and nitrous oxide (N2O), emissions when compared to continuous flooding (CF). Participatory on-farm trials were conducted from November 2017 to April 2018 in the Feni and Chattogram districts of Bangladesh. Total 62 farmers at Feni and 43 at Chattogram district, each location has 10 hectares of land involved in this study. We compared irrigation water and cost reductions, paddy yield, and CH4 and N2O emissions from paddy fields irrigated under AWD and CF irrigation methods. The mean results of randomly selected 30 farmers from each location showed that relative to the CF irrigation method, the AWD method reduced seasonal CH4 emissions by 47% per hectare and CH4 emission factor by 88% per hectare per day. Moreover, the AWD decreased the overall global warming potential and the intensity of GHG by 41%. At the same time, no noticeable difference in N2O emission between the two methods was observed. On the other hand, AWD method increased paddy productivity by 3% while reducing irrigation water consumption by 27% and associated costs by 24%. Ultimately it improved water productivity by 32% over the CF method.

Published: March 2022

Changes in glacier resources and their meltwater runoff contributions in Xinjiang are significant to the hydrological processes and water resources utilization. This study used the first and second Chinese Glacier Inventory, geomorphological and meteorological data. GIS spatial analysis technology was used to explore the characteristics of glacier change and its response to topography and climate change in Xinjiang in the last 50 years. The results show that there are currently 20,695 glaciers in Xinjiang with a total area of 22,742.55 km2 and ice reserves of about 2229.17 km3. Glaciers in Xinjiang are concentrated at 5100–6000 m. The Tianshan mountains have the largest number of glaciers. However, the Kunlun mountains have the largest glaciers and ice reserves. The scale of glaciers is significantly larger in the south than that in the north. The changes in glaciers in Xinjiang during the last 50 years are mainly receding and splitting, and their number, area, and ice reserves have decreased by 1359, 7080.12 km2 and 482.65 km3, respectively. Small glaciers are more sensitive to climate change. Glaciers are basically unchanged in regions above 6000 m. The glaciers on the south slope of mountains are more susceptible to climate change. The phenomenon of an increase in the number of glaciers but decreasing total area in the southern mountains is related to glacier extinction and splitting. Glacier development and formation are determined by the combination of topography and hydrothermal material conditions. The change of glacier areas in Xinjiang is jointly affected by climatic conditions (53.45%) and topographic conditions (46.55%), among which climatic conditions are more prominent.

Published: March 2022

The impacts of climate change on the Nile River and Grand Ethiopian Renaissance Dam (GERD) along with the increased water demand downstream suggest an urgent need for more efficient management of the reservoir system that is well-informed by accurate modeling and optimization of the reservoir operation. This study provides an updated water balance model for Aswan High Dam Reservoir, which was validated using combined heterogeneous sources of information, including in situ gauge data, bias-corrected reanalyzed data, and remote sensing information. To investigate the future challenges, the spatial distribution of the annual/seasonal Aswan High Dam Reservoir surface air temperature trends over the period from 1979 to 2018 was studied. An increase of around 0.48 °C per decade in average annual temperature was detected, a trend that is expected to continue until 2100. Moreover, a set of machine learning models were developed and utilized to bias-correct the reanalyzed inflow and outflow data available for Aswan High Dam Reservoir. Finally, a policy tree optimization model was developed to inform the decision-making process and operation of the reservoir system. Results from the historical test simulations show that including reliable inflow data, accurate estimation of evaporation losses, and including new regulations and added projects, such as the Toshka Project, greatly affect the simulation results and guide managers through how the reservoir system should be operated in the future.
Seawater Intrusion in Extremely Heterogeneous Laboratory-Scale Aquifer: Steady-State Results
Authors: Ahmed Ashraf , Robinson Gareth , Hamill Gerard , Etsias Georgios
Published: March 2022

This work used experimental and numerical methods to investigate seawater intrusion (SWI) in a complex heterogeneous laboratory-scale aquifer. We started the analysis with a homogeneous isotropic aquifer as a reference case, then moved to heterogeneous layered aquifers. The study also investigated block-wise synthetic aquifers with different configurations. The seawater wedge toe length generally decreased under heterogeneous conditions, while the freshwater–saltwater dispersion/mixing zone generally increased when compared to the homogenous case. The saltwater–freshwater interface shows a distinct gradient change across boundaries at differing hydraulic conductivities. This was attributed to streamline refraction, which caused a reduction to the angle of intrusion when transitioning from high to low permeability zones and vice versa. The refraction also affected the mixing zone, where additional spreading was also observed when transitioning from high to low permeability zones and vice versa. When low permeability zones predominated the shoreline at the saline water boundary, this produced a shorter saline wedge in the horizontal direction, but it was more expanded vertically. This study provides insight into the general processes of SWI in heterogeneous aquifers and could be used as a basis for defining conceptual models of real-world systems. It highlights the capabilities of the image analysis to capture small perturbations.

Authors: Favaretto Chiara , Martinelli Luca , Vigneron Emma M. Philippine , Ruol Piero
Published: March 2022

This paper highlights the issue of the model consistency for wave hindcasts in enclosed basins, such as lakes and lagoons. For these applications, the wind input mechanism is essential and the differences in the model approaches and available settings make it critical and difficult for the users to comprehensively understand each of the model’s capabilities and limitations. Therefore, three freely accessible regional scale spectral wave models (SWAN, STWAVE, and CMS-Wave), using the Half and Full plane modes where available, are used for wave hindcast purposes in two locations of the Garda Lake (IT). Results achieved with default settings are compared and discussed. Significant differences are found showing that, unfortunately, specific calibration, which is, however, not possible in many practical cases, is essential for applications in enclosed basins.

MSME AAA Bakery is a home industry produces white bread. This MSME produces every day to fulfil customer demand. However, there is waste in the production activities of MSME AAA Bakery, namely in the form of a relatively longer cooling time, cooling time for fresh bread between 120 minutes to 180 minutes, while at MSME AAA Bakery the cooling time for bread is 231 minutes on average. This is due to the initial rack design that hinders the cooling process. The purpose of this study was to minimize the cooling time of the bread with a prototype of a bread cooling rack redesign. The method used is Verein Deutcher Ingenieuer 2222, because it can provide a solution to the problem of long bread cooling time by redesigning the bread cooling rack. So that the relatively long cooling time of bread can be minimized and there is no long waiting time for bread production activities at MSME AAA Bakery. The results of the redesigned prototype of the bread cooling rack showed that there was a differences in the cooling time of the bread. In the experiment with the redesigned shelf prototype, the cooling time of the bread was around 90 minutes.

В данной статье рассмотрены диагностика и лечение круглогодичного аллергического ринита (КАР). Пациентам 1-й группы назначалась монотерапия (назальный спрей азеластина (аллергодил)), пациентам 2-й группы назначалась комбинированная терапия (назальный спрей азеластина в сочетании с интраназальным глюкокортикостероидом (ИГКС) (флутиказон)). Проведенное исследование подтвердило более высокую эффективность сочетанного применения азеластина (аллергодила) и ИГКС у пациентов с КАР по сравнению с монотерапией азеластином (аллергодилом).

This article discusses the diagnosis and treatment of perennial allergic rhinitis (PAR). Patients in group 1 were prescribed monotherapy (azelastine nasal spray (Allergodil)), patients in group 2 were prescribed combined therapy (azelastine nasal spray in combination with intranasal corticosteroids (fluticasone)). The study confirmed the higher efficacy of combined use of azelastine (Allergodil) and intranasal corticosteroid in patients with PAR compared with monotherapy with azelastine (Allergodil).

Puskesmas sungai tarab 2 setidaknya melayani sekitar 60 pasien setiap harinya. Data ini terus bertambah seiring dengan bertambahnya pasien yang berobat sehingga jumlah data yang begitu banyak tidak dapat dipelajari semuanya dan berakhir menjadi arsip saja. Berdasarkan latar belakang masalah diatas penulis ingin mengolah data tersebut dengan mengelompokkan penyakit berdasarkan lingkungan dengan yang bukan berdasarkan lingkungan menerapkan teknik data mining metode K-Means. K-Means adalah algoritma Clustering yang digunakan untuk mengelompokkan data kedalam beberapa kelompok dengan sistem partisi. Sehingga nantinya dapat membantu pihak puskesmas dalam memberikan penyuluhan kepada masyarakat akan pentingnya kebersihan lingkungan serta penyakit-penyakit yang timbul akibat lingkungan kurang bersih. Berdasarkan hasil pengujian algoritma k-means terhadap 15 sampel data maka diperoleh cluster_0 atau penyakit berdasarkan lingkungan sebanyak 10 items adapaun penyakitnya yang termasuk berdasarkan lingkungan adalah malaria, dbd dan dermatitis. Sedangkan cluster_1 atau penyakit bukan berdasarkan lingkungan sebanyak 5 items dan penyakit yang termasuk dalam kelompok ini adalah vertigo dan brongkitis. Berdasarkan data di atas dapat disimpulkan bahwa penyakit berdasarkan lingkungan masih banyak diderita masyarakat dan diperlukan edukasi dari pihak puskesmas agar masyarakat dapat terhindar dari penyakit tersebut.
