Authors: Chandrasekaran Hariharasudhan , Subramani Suresh Ellappa , Partheeban Pachaivannan , Sridhar Madhavan
Published: August 2023

Globally, construction and demolition wastes (C&DW) are rapidly increasing, occupying 3 billion square yards of land for landfill. In India, C&D debris reaches 150 million tons per year, leading to environmental damage and resource wastage due to poor waste management practices. This study focuses on environmental impact analysis of air and water quality for selected construction and demolition waste dump yards for Chennai metropolitan city in India for two recycling units with 15 legal dumping yards. The Internet of Things (IoT) and Geographic Information System (GIS) is used to monitor and analyze environmental effect due to C&D waste dump yard. The highest concentrations of CO and CO2 in one dump site were observed at one point, with values of 7.49 ppm and 1656.06 ppm, respectively, and at another point with the lowest values of 2.3 ppm and 619.76 ppm. TDS values ranged from 269.2 mg/L to 1347.66 mg/L, and pH values ranged from 6.4 to 11.8, indicating pollution levels in drinking water. The findings suggest that improved waste management practices are urgently needed, including better regulation and enforcement of waste disposal laws, the establishment of recycling facilities with proper air and water pollution control measures, and public education campaigns for responsible waste disposal.
Embedding Technology Interface and Digital Payment Drivers in the Unified Theory of Acceptance and Use of Technology 2 Model: Transforming Behavioral Intention to Sustained Intention
Authors: Gupta Savita , Kiran Ravi , Sharma Rakesh Kumar
Published: August 2023

Purpose: The present study was undertaken with the purpose of embedding Technology Interface drivers and Digital Payment drivers as additional drivers in the Unified Theory of Acceptance and Use of Technology (UTAUT2) to examine their influence on the Behavioral Intention of online shoppers. Technology Interface drivers include chatbots (CBs) and virtual try-on (VTO) technology. Further, this study also links Behavioral Intention with Sustained Intention to analyze whether it translates into repeated online buying. Research Methods: The study is based on a survey instrument using snowball sampling with data collected from 600 consumers from northern India. The study uses PLS-SEM for gauging the association of UTAUT2 drivers, Technology Interface drivers, and Digital Payment drivers with Behavioral Intention. Findings/Results: The results show a positive and significant association with Behavioral Intention of Technology Interface drivers and Digital Payment drivers as additional drivers to UTAUT2 drivers. UTAUT2 drivers had the highest impact (β: 0.465), followed by Digital Payment and Technology Interface drivers (β: 0.263 and β: 0.211). Further examination suggests a positive impact of Behavioral Intention on Sustained Intention (β: 0.868). The outcomes reflect that the model explained 69.5% of the variation in Behavioral Intention and 75.4% of the variation in Sustained Intention. Implications: The study suggests that Indian managers need to adopt DPM as a support service to make online shopping a worthwhile experience. Technology Interface drivers have a comparatively lower coefficient, indicating that in India, they are yet to reach the optimum level for consumers to adopt them fully. Efforts to transform Behavioral Intention into repeated online buying or Sustained Intention may go a long way in building a strong, committed community of online sellers to assist in enhancing customer experience.

Published: August 2023

This paper presents a comprehensive evaluation of a new control technique for the sphere motor system, aimed at achieving accurate tracking, robust and dispersion of vibrations. Control methods include the determination of a nonlinear model and the application of feedback linearization, followed by the optimization of the proportional derivative (PD) coefficients through the Adaptive Neuro-Fuzzy Inference System. In addition, the system’s reaction to harsh environments is managed using Long Short-Term Memory. In order to gain a deeper understanding, symmetrical environmental disturbances and trajectories are introduced during the testing phase. The results demonstrate the superior performance of the control strategy, with reduced vibrations, faster recovery and confirmed tracking accuracy. In addition, the control method shows its adaptability and reliability, as evidenced by the significant reduction in CO2 emissions compared to conventional PD control methods. The use of symmetric trajectories and visualizations further emphasizes the behavior of the system under symmetric conditions, strengthening the effectiveness and applicability of the control strategy in real-world scenarios. Overall, this study presents a promising solution for converting complex systems under different conditions and making them potentially applicable in various industrial contexts.
On Ulam Stability with Respect to 2-Norm
Authors: Brzdęk Janusz
Published: August 2023

The Ulam stability of various equations (e.g., differential, difference, integral, and functional) concerns the following issue: how much does an approximate solution of an equation differ from its exact solutions? This paper presents methods that allow to easily obtain numerous general Ulam stability results with respect to the 2-norms. In four examples, we show how to deduce them from the already known outcomes obtained for classical normed spaces. We also provide some simple consequences of our results. Thus, we demonstrate that there is a significant symmetry between such results in classical normed spaces and in 2-normed spaces.

Published: August 2023

The interactions between specific snake venom toxins and muscle constituents are the major cause of severe muscle damage that often result in amputations and subsequent socioeconomic ramifications for snakebite victims and/or their families. Therefore, improving our understanding of venom-induced muscle damage and determining the underlying mechanisms of muscle degeneration/regeneration following snakebites is critical to developing better strategies to tackle this issue. Here, we analysed intramuscular bleeding and thrombosis in muscle injuries induced by two different snake venom toxins (CAMP—Crotalus atrox metalloprotease (a PIII metalloprotease from the venom of this snake) and a three-finger toxin (CTX, a cardiotoxin from the venom of Naja pallida)). Classically, these toxins represent diverse scenarios characterised by persistent muscle damage (CAMP) and successful regeneration (CTX) following acute damage, as normally observed in envenomation by most vipers and some elapid snakes of Asian, Australasian, and African origin, respectively. Our immunohistochemical analysis confirmed that both CAMP and CTX induced extensive muscle destruction on day 5, although the effects of CTX were reversed over time. We identified the presence of fibrinogen and P-selectin exposure inside the damaged muscle sections, suggesting signs of bleeding and the formation of platelet aggregates/microthrombi in tissues, respectively. Intriguingly, CAMP causes integrin shedding but does not affect any blood clotting parameters, whereas CTX significantly extends the clotting time and has no impact on integrin shedding. The rates of fibrinogen clearance and reduction in microthrombi were greater in CTX-treated muscle compared to CAMP-treated muscle. Together, these findings reveal novel aspects of venom-induced muscle damage and highlight the relevance of haemostatic events such as bleeding and thrombosis for muscle regeneration and provide useful mechanistic insights for developing better therapeutic interventions.

Published: August 2023

White spot disease (WSD) is a severe viral threat to the global shrimp aquaculture industry. However, little is known about white spot syndrome virus (WSSV) transmission dynamics. Our aim was to elucidate this in Litopenaeus vannamei using peroral in vivo WSSV challenge experiments. We demonstrated that WSD progression was rapid and irreversible, leading to death within 78 h. Viral DNA shedding was detected within 6 h of disease onset. This shedding intensified over time, reaching a peak within 12 h of the time of death. Isolating shrimp (clinically healthy and diseased) from infected populations at different time points post-inoculation showed that host-to-host WSSV transmission was occurring around the time of death. Exposing sentinels to environmental components (i.e., water, feces, molts) collected from tanks housing WSSV-infected shrimp resulted in a significantly (p-value < 0.05) increased infection risk after exposure to water (1.0) compared to the risk of infection after exposure to feces (0.2) or molts (0.0). Furthermore, ingestion of WSSV-infected tissues (cannibalism) did not cause a significantly higher number of WSD cases compared to immersion in water in which the same degree of cannibalism had taken place.

Published: August 2023

Background: The COVID-19 pandemic has had a significant impact on the epidemiology of respiratory viruses. Non-pharmaceutical interventions (NPIs) led to a dramatic reduction in respiratory infections. However, the long-term effects on respiratory virus epidemiology remain unclear. Materials and Methods: We conducted a comparative study on hospitalized pediatric patients with respiratory illness during two seasons: 1 October 2021 to 15 March 2022 and 1 October 2022 to 15 March 2023. We compared the type of virus, mean duration of hospitalization, and disease severity. Results: In the first season, 47.1% of patients (65/138) tested positive for at least one respiratory virus, with respiratory syncytial virus (RSV) being the most frequent (23.2%). In the second season, 82.9% of patients (102/123) tested positive, with RSV and Rhinovirus being the most prevalent (28.38% and 27.03%, respectively). Other viruses, such as Influenza A/B, Metapneumovirus, and Adenovirus, also showed increased prevalence. Disease severity and mean duration of hospitalization were similar between the two seasons. Conclusions: Our study highlights increased prevalence in respiratory viruses, including RSV and Rhinovirus, following the easing of NPIs. The prevalence in respiratory viruses, including RSV and Rhinovirus, increased in the second season compared to the first one. Interestingly, RSV’s peak incidence shifted from February to November. The emergence of rhinovirus as the most prevalent respiratory virus during certain months suggests viral competition and dynamic changes in viral circulation. The overall severity of respiratory infections remained relatively stable between the seasons.

Ebola virus is a zoonotic pathogen with a geographic range covering diverse ecosystems that are home to many potential reservoir species. Although researchers have detected Ebola virus RNA and serological evidence of previous infection in different rodents and bats, the infectious virus has not been isolated. The field is missing critical knowledge about where the virus is maintained between outbreaks, either because the virus is rarely encountered, overlooked during sampling, and/or requires specific unknown conditions that regulate viral expression. This study assessed adipose tissue as a previously overlooked tissue capable of supporting Ebola virus infection. Adipose tissue is a dynamic endocrine organ helping to regulate and coordinate homeostasis, energy metabolism, and neuroendocrine and immune functions. Through in vitro infection of human and bat (Eptesicus fuscus) brown adipose tissue cultures using wild-type Ebola virus, this study showed high levels of viral replication for 28 days with no qualitative indicators of cytopathic effects. In addition, alterations in adipocyte metabolism following long-term infection were qualitatively observed through an increase in lipid droplet number while decreasing in size, a harbinger of lipolysis or adipocyte browning. The finding that bat and human adipocytes are susceptible to Ebola virus infection has important implications for potential tissue tropisms that have not yet been investigated. Additionally, the findings suggest how the metabolism of this tissue may play a role in pathogenesis, viral transmission, and/or zoonotic spillover events.
Energy Status of Stygophilous Amphipod Synurella ambulans as a Promising Biomarker of Environmental Stress in the Hyporheic Zone
Authors: Redžović Zuzana , Erk Marijana , Gottstein Sanja , Cindrić Mario
Published: August 2023

The hyporheic zone (HZ) is a sensitive ecotone in river ecosystems because of its biodiversity and susceptibility to human activities. Hyporheic fauna are exposed to multiple stressors that affect the physiology and metabolism of organisms and ultimately ecosystem functioning and biodiversity. This study aimed to quantify adenine nucleotides in the stygophilous freshwater amphipod Synurella ambulans and to evaluate the potential of adenylate energy charge (AEC) as a physiological biomarker of general stress in the HZ of the Sava River at sites with different intensities of environmental and anthropogenic stress. Field studies were conducted seasonally (in December 2018 and April, July, and October 2019) at two sampling sites, one upstream (1-UP) and the other downstream (2-DOWN) of the discharge from the wastewater treatment plant using the standard piston pump. The amphipod population from site 1-UP had significantly higher AEC values than the population from site 2-DOWN in all seasons except summer. Coordinated changes in AEC values with the ATP/ADP ratio indicated differences in energy status between the two populations. However, no changes in the apparent equilibrium constant of adenylate kinase were observed, except in spring at site 1-UP. Multiple linear regression models showed the strongest associations of AEC with Fe and Zn accumulated in amphipods, followed by environmental factors (conductivity, dissolved O2, and concentrations of nitrites and phosphates in the interstitial water). AEC was shown to be a useful index of environmental stress in S. ambulans because it can directly measure the change in available energy and thus the metabolic stress to which the organism is exposed. Finally, seasonal and spatial variations in AEC values reflected ecological status in the HZ.
Experimental and DEM-CFD Coupling Investigations on the Characteristics and Mechanism of Seepage Erosion for Cohesionless Soil
Authors: Su Hui , Dai Da , Zhang Ting , Yang Jiaqi , Mu Zhiyong
Published: August 2023

Seepage erosion is one of the main reasons for the local collapse or instability of embankments. To investigate the characteristics and mechanism of seepage erosion for cohesionless soils, model tests using an independently developed seepage erosion device and numerical simulations based on a discrete element method-computational fluid dynamics (DEM-CFD) coupling model were carried out. The results show that the seepage erosion process of cohesionless soil could be characterized by four stages: stable seepage, upward migration of fine particles, boiling of sand samples, and erosion damage. The skeleton structure of a soil sample under seepage flow was continually changed due to the loss of fine soil particles, which resulted in a significant decrease in the sample strength and could, ultimately, lead to the failure of the sample. The results of this study can provide references and bases for the design, construction, and long-term service of embankments or earth dams under complex seepage conditions, reducing the risk of seepage erosion.

Published: August 2023

This study is the first to report the high performance of calcined natural sphalerite as a heterogeneous catalyst (Catalyst) in the piezo- and photocatalytic degradation of pharmaceuticals (bezafibrate and ceftriaxone) using high-frequency ultrasound (US, 1.7 MHz) and ultraviolet-light-emitting diodes (LED, 365 nm). The kinetic comparison showed that piezo-photocatalysis (LED + US + Catalyst) was more efficient than photocatalysis (LED + Catalyst) for degrading both contaminants in deionized water as well as in surface river water at natural pH (7.9). Despite reducing degradation rates (~1.7 times) in river water due to the scavenging effect of its constituents, ceftriaxone and bezafibrate were degraded by 77% and 48% after 1 h of exposure, respectively. Adding H2O2 increased the corresponding pseudo-first-order rate constants, and the complete degradation of ceftriaxone was achieved. However, the contribution of ultrasound at a given intensity was hidden, which resulted in a similar performance of piezo-photocatalysis and photocatalysis for treating river water. No pronounced synergy between the piezo- and photocatalytic processes was observed in the experimental conditions used. Nevertheless, the H2O2-assisted piezo-photocatalysis using high-frequency US, LED, and natural catalysts can be considered a novel and effective strategy for eliminating pharmaceuticals from real water without pH adjustment.

Published: August 2023

The purpose of this research is to describe the analysis of knowledge to be taught on limit of function. This research is part of the didactic transposition research on the concept of limit of function which consists of four stages. Qualitative research with descriptive method is used in this study. The target is a differential calculus course taught in the first semester at a university in Aceh. Data collection techniques consist of documentation studies and unstructured interviews. Analysis of calculus text book documents, especially on limit functions, was carried out using a praxeology approach. The results of the analysis show that the description of the differential calculus course contains material on the real number system, functions and graphs, limits of functions, continuity of functions, derivatives of functions, and applications of derivatives. This is different from the presentation of material in RPS which is compiled by a team of lecturers supporting differential calculus courses. For presentation of material in calculus textbooks, the concept of the limit of a function begins with an intuitive or informal introduction to the concept. Several cases are given to deepen the concept of limits through graphs, analytics, and numbers.

In the post-epidemic era, Chinese investment in the “Belt and Road” countries faces significant opportunities and challenges. Firstly, global markets actively seeking recovery have given multinational investors more opportunities. China, with its strict and effective epidemic control, has preceded the rest of the world in the period of epidemic stabilization and Chinese investors have also seized the opportunity of economic reversal and recovery. However, it is worth noting that protectionism and anti-globalization forces around the world have also taken advantage of the COVID-19 epidemic to become more prevalent, and Chinese outbound investment will face a more complex environment and more intense confrontation. In this complex environment, choosing to develop investment sectors that are more compatible with the interests of the host country can effectively reduce the risk of investment. Therefore, this paper analyses the selection of industries for China's investment along the “Belt and Road” from multi-dimensional perspectives. SWOT analysis is used to explore the advantages and disadvantages of industries in the process of "going global" in four dimensions: opportunities, advantages, disadvantages and challenges. Finally, recommendations are given for the selection of industries for China's investments in countries along the “Belt and Road”. Key words: Belt and Road, China's investments, post-pandemic

Published: August 2023

This research emphasizes the importance of involving young women in various activism. Problems arise when young women are often considered immature to be involved in social and political movements. Apart from being supported by a patriarchal mindset that tends to subordinate women’s experience, there is an intersectional problem where young people need more knowledge to make changes. In fact, one way to encourage active representation of women in political space is to encourage involvement from a young age. This research explores the activism experiences of young women who influence their respective communities. Data was collected through Focus Group Discussion (FGD) and strengthened through literature studies. The data is managed using a political participation theory approach, as well as the influence of affect theory in digital activism. The findings in this research show that young women’s knowledge is just as essential in the political space. Their advocacy is full of the spirit of the times, so they can have a strong influence on other young women through the community they have built.
Complications of uneventful phacoemulsification on the first postoperative day: to determine the necessity of the first day review
Authors: Seow Sieng Teng , Tajunisah Begam Binti Mohamed Iqbal
Published: August 2023

Purpose: To establish the type and number of complications detected on the first postoperative day and to determine the necessity of the first day review.

Study design: Clinical audit.

Methods: This is a retrospective review of 297 patients who underwent routine phacoemulsification cataract surgery by qualified ophthalmologists and trainees from September to December 2020 at our day-care operation theatre. All cases of uncomplicated phacoemulsification were analysed for the types and frequency ofcomplications on postoperative day one.

Results: Of 297 cases of routine cataract surgery, 6.7% of cases were excluded due to intraoperative complications. Of the remaining 277 cases, a total of 54 cases (19.5%) were found to have complications on day 1 postoperative review. These included raised intraocular pressure (67.0%), epithelial defect (20.0%), intense inflammation with presence of fibrin (5.0%), retained soft lens matter (4.0%), retained fibres (2.0%), and exposed corneal suture (2.0%). Two patients (0.7%) needed the removal of soft lens matter. Of 36 cases of raised intraocular pressure, 1 patient required anterior chamber paracentesis for retained viscoelastic, 18 patients required topical antiglaucoma medication, 15 patients needed systemic oral acetazolamide, and 2 patients with pre-existing glaucoma were instructed to continue their antiglaucoma medications.

Conclusions: Following uneventful phacoemulsification, only 19.5% of patients were found to have complications on day 1 postoperative review. The most frequent complication was raised intraocular pressure, which can be detected on the day of surgery. Reviewing patients on the same day of surgery can reduce workload and demands on clinician time. It can also significantly reduce health care costs without compromising patient safety.

Two new endemic species of Anaulacodesmus Attems, 1898, a genus of millipede native to Chile, are described. Anaulacodesmus panterae sp. nov. and Anaulacodesmus picassovallebuonai sp. nov. were discovered in fragments of Valdivian temperate forest in southern Chile. These species can be separated from the rest of the congeners based on their larger size and gonopodal characters. A. panterae from Valdivia (Los Ríos Region), has distally swollen gonopods, a trait it shares with A. dahli Chamberlin, 1957 and a A. enkrates (Attems, 1898). Anaulacodesmus picassovallebuonai sp. nov., from Temuco and Lake Villarrica (La Araucanía Region), is morphologically similar to A. bifidus Golovatch, 2014 with which it shares the bifid structure of the telopodite. Detailed descriptions and character illustrations are provided for both species.

Published: August 2023

Castor is one of the important oil crop, the shelling process of which directly affects the quality of castor seeds. In the process of shelling, the shelling force of castor is an important index to study its damage. The castor capsule model was established and the shelling test machine was established based on the discrete element method. Then the extrusion law of castor capsule during shelling was analyzed. The shelling process is divided into three stages, which are the Initial stage, stable shelling stage and the final stage. The force law of shelling process is analyzed. The results show that with the increase of rotating speed, the maximum force decreases from 68.78 to 68.10 N, the maximum speed increases from 8.92 to 12.99 m/s, the force of inner drum increases from 509.34 to 533.14 N, and then decreases to 456.15 N. The shelling increases from 91.23% to 91.28%, and then decreases to 88.89%. With the increase of filling amount, the maximum force increases from 55.86 to 76.93 N, the maximum speed decreases from 12.99 to 10.86 m/s, the force of inner drum increases from 338.58 to 603.364 N, and the shelling rate changes from 91% to 90.05%. This study can provide theoretical support for the design of castor shelling machine.

This study proposes a monocular vision navigation control system based on PID-fuzzy control, which travels along the edge of the path. It collects path image information through monocular vision, identifies the path edge through image processing to determine the preview point, and uses a combination of PID and fuzzy control to design a controller to track the preview point for path navigation. Firstly, coordinate calibration and conversion were performed on the monocular camera, achieving coordinate conversion from the image coordinate system to the world coordinate system. The accuracy of the calibration results was verified through experiments. According to the navigation strategy of driving along the edge of the path, the world coordinate equation of the path edge is obtained through image processing technology, and the preview point tracked by the navigation system is determined. The navigation parameters are determined based on the position of the preview point. The PID fuzzy controller system designed in this study can switch different control methods based on the position of the preview point. Finally, an experimental verification was conducted on the monocular visual navigation system of the control system. The verification results showed that the average error of the navigation control system in tracking the path when driving in a straight line was 0.039 m, the average error when turning left was 0.079 m, and the average error when turning right was 0.121 m. The error range can meet the basic requirements of agricultural robot farmland operations. Research has shown that the navigation strategy based on PID-fuzzy joint controller to track the preview point along the path edge has a good effect on the visual navigation control system of agricultural robots. This study provides important reference value for the research and development of monocular visual navigation systems of agricultural robots.

Published: August 2023

Çalışma, “Distopya mimarlığının yakın gelecekteki tasarım potansiyelleri nelerdir?” sorusuna cevap arar ve bu potansiyeller arasındaki bağların ilişkilerine ait bir döküm sunmayı hedefler. Bu bağlamda, literatür taraması yoluyla, ütopya ve distopya kavramları arasındaki benzerlikler ve farklar ile kavramların birbirlerinin tanımlarını ve çalışma alanlarını besledikleri noktalar irdelenir. Öncü figürlerin mekân bağlamında öne çıkan öneri ve vurguları tartışılır, örtük ilişkiler değerlendirilir. Çalışma, distopya mimarlığının mekân ölçeğinde umut ve trajedinin izini sürerek, geleceğe ilişkin özgün bir mekânsal kavrayış geliştirilebilmesine odaklanır. Greene ütopya ve distopya kavramlarının anlamsal benzerlik ve farklılıklarına, Zahrani ütopyanın sonuna, Pereira mimarlığın distopik kurgu yazımındaki rolüne, MacLeod ve Ward çağdaş şehirlerdeki distopik öğelerin ilişkilenme biçimlerine, Was, bilimkurgudaki mimari detaylara, Knutz tasarım kurgusundaki yeni tipolojik arayışlara, Coleman mimarlıkta ütopyanın kronikleşen sorunlarına, Crosbie ütopya ve distopyadaki ana figür arayışına, Schneekloth dünyayı yeniden üreten ve bozan temalara, Kraftl konut bağlamında umut ve hazza, Sprecher ve Leblanc atopyaya, Scott tekno-ütopyaya, Mihailescu distopik kurguya, Miller feminist ideolojideki post-apokaliptik umut etme biçimlerinin distopik yanına ve Picon, şehir üzerinden yakın geleceğin temalarının okunma biçimlerine değinir. Bu doğrultuda, distopik kolajların, geçmiş ve şimdiki zamandan yoğun biçimde beslenen ve yüzeysel önyargıların aksine, gerçekliğe büsbütün bağlı temalar üzerinden geliştirilebildiği sonucuna varılır. Distopya mimarlığı, ütopya mimarlığının bir karşıtı değil, bir ardılı olarak varlığını sürdürmekte ve fütüristik temaları, mevcut değişkenler üzerinden yorumladığı ölçüde mekânsal bir devingenlik kazanmaktadır.
