Barriers Hindering the Successful Deployment of GLSS in Organizations: Findings from an Empirical Study

Given the growing interest in manufacturing’s environmental effects, understanding the impact of improvement strategies on sustainability is critical. This study focuses on the implementation of Green Lean Six Sigma (GLSS) in the Mexican manufacturing sector, an area where research is limited, particularly concerning the barriers to successful outcomes. Through the development of a structural equation model using SPSS software,,version 25, 64-bit edition, key barriers such as lack of investment, insufficient participation, ineffective infrastructure, and lack of training were identified as the primary challenges to GLSS implementation. This study also highlights the interrelationships between these barriers and their influence on project success, emphasizing the role of insufficient participation as a critical mediating factor. This insight allows for a deeper understanding of how these obstacles affect the benefits of GLSS initiatives. The findings offer valuable guidance for researchers and practitioners, providing tools to enhance the effectiveness of GLSS implementation in the manufacturing industry. The study’s marginal contribution lies in its identification of key barriers and the introduction of insufficient participation as a mediating factor, offering a more comprehensive understanding of their impact on project success and contributing to improved GLSS adoption strategies.

Mechanical and dynamic characteristics for the CFRP, GFRP, and hybrid composites exposed to HCl environment

In the current study, the low-velocity impact (LVI) characteristics of carbon fiber-reinforced polymer (CFRP), glass fiber-reinforced polymer (GFRP), and hybrid composites before and after the corrosive environment exposure were investigated. In this regard, CFRP, GFRP, and hybrid composites were subjected to LVI and tensile loadings after being kept in a 10% diluted HCl environment for 1 week and 1 month, and the impacts of the corrosive environment on the composites’ dynamic and mechanical responses were determined by comparing the outcomes of the control and aged specimens. LVI tests for CFRP, GFRP, and hybrid composites were carried out by transferring 25.2 and 11.2 J impact energy to the specimens with two impact velocities of 3 and 2 m/s, respectively, and thus, the effects of impact energy and hybridization were investigated. Moreover, tensile tests were conducted for the control and aged specimens with 2 mm/min crosshead speed, and thus, the effects of fiber material, hybridization, and corrosive environment on the mechanical properties were determined. The study found that CFRP composites had higher stiffness than GFRPs, whereas hybrid composites exhibited dynamic responses between CFRP and GFRP, as expected. On the other hand, it turned out that the composites absorbed most of the impact energy, which was interpreted as being absorbed by the damage of fiber-reinforced composites, which stand out with their brittle characteristics. Furthermore, it was discovered that the damage severity elevated as expected with a longer aging time, which was attributed to the corrosive liquid attacking the fibers, matrix, and fiber/matrix interfaces and reducing strength. It was also observed that, as predicted, the corrosive effects generally resulted in a reduction in tensile responses, including ultimate strain and tensile strength.

Gender differences in the effects of urban environment on nighttime exercise behaviours: a qualitative study

ObjectiveWith the acceleration of urbanization, nighttime exercise behaviours have rapidly emerged. Existing research indicates a correlation between urban environments and physical activity; however, studies focusing specifically on nighttime are still insufficient, particularly regarding gender differences. This study aims to identify the key factors in urban environments that influence residents’ nighttime exercise behaviours and to explore the gender differences within these influences.MethodsPurposeful sampling was employed to conduct semi-structured interviews with 30 residents who regularly engage in nighttime exercise. All transcribed interviews were analyzed using Colaizzi’s phenomenological data analysis method.ResultsThe findings revealed that physical environment and environmental perception are the two primary factors influencing nighttime exercise behaviour. These factors are further divided into 10 specific sub-themes: lighting, green spaces, site facilities and layout, traffic coherence, entertainment facilities, smart sports equipment, sense of safety, convenience, pleasure, and sense of belonging.ConclusionFemales demonstrate a heightened sensitivity to the perception of the physical environment, placing greater emphasis on the feelings and experiences it provides. Males, on the other hand, focus more on the direct impact of the physical environment, such as its specific effects on exercise performance. Future urban planning and public policy should give greater consideration to gender differences in the use of urban exercise facilities, ensuring that nighttime exercise environments meet the needs of residents of different genders. This approach will contribute to enhancing overall community vitality and improving residents’ health.

Wheat (Triticum aestivum) response under soil moisture and crop water stress based irrigation scheduling at variable nitrogen regimes

The field experiment was conducted during winter (rabi) seasons of 2021–22 and 2022–23 at research farm of ICAR-Indian Agricultural Research Institute, New Delhi to examine the water productivity and crop response under soil moisture and crop water stress based irrigation scheduling at variable nitrogen regimes in wheat (Triticum aestivum L.). Experiment was conducted in a split-plot design (SPD) design comprised of 3 irrigation regimes in main plots and 5 graded nitrogen (N) levels in sub-plots, replicated thrice. Irrigation scheduling regimes included I1 (50% available soil moisture depletion-ASMD); I2 (CWSI i.e. crop water stress index based); and I3 (Conventional crop growth stage based). The 5 graded N levels included 0 (N0); 50 (N1); 100 (N2); 150 (N3); and 200 (N4) kg N/ha. Results showed that 50% DASM based irrigation significantly increased grain yield (11.28 and 6.30%), straw yield (5.33 and 5.70%), dry matter accumulation (5.65 and 5.44%), water productivity (11.37 and 6.19%), root length (15.89 and 44.48%), root weight (11.63 and 12.77%) and grain N uptake (20.88 and 14.52%) compared to conventional crop stage based irrigation during 2021–22 and 2022–23, respectively. Among the graded N application, maximum grain yield (4.78 and 4.82 t/ha) and crop water productivity (13.91 and 15.09 kg/ha-mm) were recorded with treatment N4 (200 kg N/ha), but remained statistically at par with N3 (150 kg N/ha) due to the marginal increment beyond 150 kg N/ha. Overall, soil moisture based irrigation at 50% MAD with 150 kg/ha N application proved to be the most effective and economical approach to enhance dry-matter accumulation, yield and water productivity with saving from harmful environmental effects ascending from excessive nitrogen use.

Abstract 4132875: Living Address Environmental Biotope Affects the Risk of Coronary Obstruction and Myocardial Ischemia Detected by Coronary Computed Tomography

Background: Several studies reported positive associations between air and noise pollution exposure and coronary artery calcification, but environmental effects on coronary obstruction and flow remain largely unknown. Hypothesis: Distance to road and airport, air pollution, and residential green space are linked to coronary artery obstruction and myocardial ischemia. Low CV-risk patients develop coronary obstruction due to environmental factors, while high-risk patients are more prone to develop myocardial ischemia. Methods: Consecutive patients screened by coronary CT angiography for stable chest pain between 01/01/2019 and 31/12/2020 were included in a registry. Distance to airport and major road, and exposure to PM2.5, NO 2 and normalized difference vegetation index (NDVI) were modelled at patients’ living address. Risk of obstructive coronary artery disease (OCAD, stenosis ≥50%) and abnormal fractional flow reserve (FFR CT <80%) was assessed using propensity score (PS)-adjusted logistic regression. Subgroup analysis was performed according to gender and Framingham CV-risk categories. Results: We enrolled 2620 patients, including 420 (16%) FFR CT analyses. OCAD was reported in 518 (20%) patients and abnormal FFR CT in 276 (11%). People with OCAD lived closer to the airport (10.841 [7.869-19.022] km vs. 12.297 [8.691-22.843] km, p<0.001). Distance to airport decreased OCAD risk (OR 0.983, 95%CI 0.974-0.992, per 1 km) in univariate analysis, with the association present in male, female, and low-risk patients. After PS-adjustment, a trend of association was present between airport distance and abnormal FFR CT risk (OR 0.986, 95%CI 0.969-1.003, per 1 km). Road distance tended to decrease OCAD risk in univariate and PS-adjusted analysis, in the general (OR 0.928, 95%CI 0.808-1.309; and OR 0.928, 95%CI 0.840-1.021, per 1 km) and high-risk population. NO 2 exposure tended to increase OCAD risk in univariate analysis (OR 1.012, 95%CI 0.997-1.027, per 1 µg/m 3 ), with the association only present in female patients, and disappearance after PS-adjustment. PM2.5 exposure showed no associations, while NDVI tended to increase OCAD risk in low-risk patients after PS-adjustment. Conclusion: Residential distance to airport is the major risk component compared to other urban exposome factors studied in this epidemiological observation. Green space tends to exert a cardioprotective effect in low-risk patients, whereas living close to major road worsens the risk in high-risk patients

How Road and Rail Transport Respond to Economic Growth and Energy Prices: A Study for Poland

Transport drives economies. This statement covers complex and multifaceted economic, environmental, and political issues. The literature mainly describes the unidirectional impact of transport on the economy, and far less often bilateral or reverse impacts. This is the context in which this study was conducted. The question of whether the economy (GDP and exports and imports) and energy prices (crude oil and diesel) have an impact on road and rail transport in Poland was examined. The research was based on correlation methodology and VAR modelling for the January 2010–March 2024 period (quarterly data). It was found that there is no sufficiently strong basis to speak of an inverse relationship, i.e., that the economy is the cause of transport. This confirms the majority of studies, but it has been shown that this relationship occurs in the current period. And this statement means that both road transport, which is developing, and rail transport, which is declining in Poland, are able to serve the economy on a continuous basis. Moreover, rail transport is positively affected by changes in fuel prices, but the basic energy resource used in rail transport is not fuel but electricity. Therefore, as fuel prices rise, investment in rail transport or combined transport can have positive economic and environmental effects in the future.

Multiple environmental regulations and green technology innovation: a boundary theory perspective

Purpose Based on boundary theory, the authors try to clarify the boundaries of multiple environmental regulations. This paper aims to explore the strategic choices of multiple environmental regulations, analyze their spatial impact on green technology innovation and clarify the implementation priorities of multiple environmental regulations in various regions. Design/methodology/approach The authors construct an asymmetric response model based on the boundary theory perspective to analyze the strategic choices of different environmental regulations. In addition, dynamic spatial econometric methods are used to empirically analyze the differentiated regulatory boundaries of command-control type, market-incentive and voluntary-participation in environmental regulations and their spatial effects on green technology innovation. Findings Strict compulsory boundaries are formed in China when the command-control and market-incentive types are selected in a dynamic spatial and competitive game environment. When voluntary participation is selected, strict compulsory or loose basic boundaries are formed in each region. The command-control type is highly dependent on geographical distance, the market-incentive type is more dependent on an economic connection and the voluntary-participation type has obvious spatial spillover effects under the spatial weight matrix of geographical distance and economic connection. When Eastern China chooses voluntary participation in environmental regulation, the incentive effect on green technology innovation is the strongest. Middle China is the market-incentive type, and Western China is the command-control type. Command-control type and market-incentive type form strong complementary effects in dynamic spatial environments. Originality/value From the boundary theory perspective, this study analyzes the differentiated dynamic spatial boundaries of command-control, market-incentive and voluntary-participation in environmental regulations. Analyze the spatial impact of multiple environmental regulations on green technology innovation and clarify the implementation priorities of multiple environmental regulations in various regions.

The Impact of Entrepreneurial Leadership, Business Environment, Digital Literacy, and Religiosity on Msme Performance: The Mediating Role of Innovative Behavior in Pekanbaru

This study examines the influence of entrepreneurial leadership, business environment, digital literacy, and religiosity on the performance of micro, small, and medium enterprises (MSMEs) in Pekanbaru, with innovative behavior as a mediating variable. Using a sample of 300 MSME entrepreneurs and analyzed through Partial Least Squares (PLS) Structural Equation Modeling (SEM), the research finds significant direct effects of entrepreneurial leadership (β = -0.204, p = 0.047), business environment (β = 0.225, p = 0.007), digital literacy (β = 0.139, p = 0.022), and religiosity (β = 0.271, p = 0.011) on business performance. The mediating role of innovative behavior is only significant in the relationship between religiosity and business performance (β = 0.162, p = 0.012). The findings emphasize the critical role of religiosity and innovative behavior in improving MSME performance. This research contributes to the growing literature on MSMEs by demonstrating how leadership, environment, digital skills, and religiosity shape performance outcomes.

An examination of scene complexity’s role in cybersickness

This study explored the effects of scene complexity factor on cybersickness. In this between-subjects experiment, 44 participants played the Pendulum Chair VR game, half with a simple scene and half with a complex scene. The complex scene featured higher optic flow (lower-level perceptual factor) and higher familiarity (higher level factor). Dependent variables were cybersickness and task performance. Results were unexpected in that cybersickness did not differ significantly between the simple and complex scenes. These results suggest that the impact of optic flow and familiarity on cybersickness may be affected by each other or other factors, making them unreliable predictors of cybersickness if considered alone. Both lower level and higher-level factors would benefit from further research to deduce the conditions under which they affect cybersickness. VR designers could consider that optic flow and familiarity alone are not reliable factors when predicting the cybersickness-inducing effects of a new environment.

Combined effects of urbanization and climate variability on water and carbon balances in a rice paddy-dominated basin in southern China

Abstract Urbanization is known to elevate storm runoff, but how it influences carbon cycle and ecosystem productivity through altering the evapotranspiration (ET) process is less clear. We examined the combined effects of urbanization including change in impervious surface area (ISA) and climate variability on the water and carbon balances of the Qinhuai River Basin (QRB) over 2001–2018. QRB represents a typical rice paddy-dominated region that experienced rapid urbanization in southern China. We improved a monthly scale water supply stress index ecosystem service model by integrating local eddy flux measurements and high-resolution remote sensing data. We found a significant downward trend in both ET (−4.6 mm yr−1, p < 0.05) and gross primary productivity (GPP) (−10.4 gC m−2 yr−1, p < 0.05) but a significant upward trend in water yield (Q) (+28.6 mm yr−1, p < 0.05). These ecosystem function changes coincided with a 96% increase in urban areas, 1.9-fold increase in ISA, and a 37% reduction in rice paddy fields. The mean annual watershed GPP decreased from 1048 gC m−2 to 998 gC m−2 while the annual Q increased from 284 mm to 669 mm from 2001 to 2018. Scenario modeling experiments suggested that the negative impacts of loss of rice paddy fields and increase in ISA on ET and GPP overwhelmed the positive impacts of climate warming. The reduction in GPP and increase in Q were largely attributed to the increases in ISA, not necessarily due to changes in land use types (e.g. urban area). The expansion of urban area, increase in ISA and reduction in leaf area index, and increase in precipitation explained the increase in Q. Our research offers insight about the interactions of carbon and water cycles through the critical ET processes under a changing climate and land surface characteristics at a watershed level. Our modeling tool and analysis provides land managers and policy makers information for designing effective ‘Urban Nature-based Solutions’ to mitigate the negative environmental effects of urbanization on carbon and water resources.

Evaluation of solar distiller performance using steel wool pads, internal reflectors, and woven wire mesh: economic, environmental, and sustainability analysis

Abstract Different researches were performed by using thermal storage materials, solar concentrators, reflectors, and other technologies to increase the productivity of solar stills. The main objective of the present study is to enhance the basin solar still productivity by using ecomaterials from the wastes of workshops and factories. So, this study presents an experimental investigation of basin solar still performance using steel wool pads, internal reflectors, and woven wire mesh. The experimental setup was performed at Suez Canal University, Ismailia City, Egypt. Two solar stills were included: one represents the conventional design (CSS), and the second one is the modified with steel wool pads, internal reflectors, and woven wire mesh (MSS). Both solar stills were evaluated under identical climate conditions, considering water depths of 1, 2, 3, and 4 cm, and the required parameters were measured and tabulated during the working days. The results indicated that incorporating these modifications led to a notable increase in accumulative productivity and daily thermal efficiency with minimum cost per liter. The MSS enhanced the daily yield and thermal efficiency by 22.1% and 28.0%, respectively, versus CSS at a water depth of 1 cm. In addition, the energy production factor (EPF), energy payback time (EPT), and the average exergy waste were 1.2 years, 0.85, and 400.2 J, respectively, for MSS. The annual exergy output, environmental effect factor (EEF), improvement potential (IP), and sustainability index were 462.7 kWh, 10.4, 290.6 W, and 1.09, respectively, for MSS. Finally, the cost per liter and the annual CO2 reduction over a lifetime for CSS and MSS were 0.023 $/l, 17.4 tons, and 0.11 $/l, 20.4 tons, respectively. These results align with and reinforce previous publications on desalination, highlighting the potential of these modifications for addressing the pressing challenges of affordable and efficient water using solar energy.

Biodegradation of Polyethylene Using Bacillus tropicus Isolated from Sewage Wastewater Treatment Plant

One of the most pressing environmental problems contemporary civilizations confront is the ever-increasing amount of plastic waste. Because of their impact on every living thing, these wastes are seen as a major issue on a global scale. To counteract the harmful environmental effects caused by conventional disposal methods, it is critical to show that eco-friendly alternatives are viable. Biodegradation is one of the best eco-friendly methods for removing plastic waste. In this study, we aimed to identify bacteria from sewage wastewater treatment plants (SWWs) that could degrade low-density polyethylene (LDPE). Bacterial strains isolated from sewerage wastewater were incubated for 120 days in 50 mL of minimal salt media (MSM) containing 60 mg of low-density polyethylene (LDPE). After four months, our research revealed that Bacillus tropicus (SH4) demonstrated significant potential, degrading the LDPE up to 21.6%. We observed the changes after biodegradation using FTIR, GC-MS, and SEM analysis. In conclusion, microorganisms extracted from sewage wastewater possess the ability to mitigate plastic contamination in aquatic ecosystems. Future proteomics and genome investigations are necessary to elucidate the enzymes and metabolic processes implicated in plastic breakdown.

Preventive Effects of Polyprenols from the Needles of Aabies sibirica under the Influence of Adverse Factors

Currently, biologically active substances of natural origin are widely used as preventative agents. The search and development of new drugs for the prevention and correction of nonspecific disorders of the body’s resistance to adverse effects in environment continues. A preclinic assessment of the effectiveness of polyprenols from Siberian fir Abies sibirica was carried out when used prophylactically for two weeks. It has been shown that the effect of polyprenols is manifested by antioxidant, anabolic activity and stimulation of hematopoiesis in an experimental model of combined poisoning with carbendazim and X-ray irradiation.

Awareness on Carbon Footprints Among Politeknik Sultan Haji Ahmad Shah Students

In this study, we aimed to investigate the awareness and actions related to carbon footprints among Politeknik Sultan Haji Ahmad Shah (Polisas) students. As the world's greenhouse gas emissions continue to rise globally, it is critical to assess people's attitudes and actions in tackling this environmental challenge, especially those of the younger generation. In addition to evaluating the students' views about the impacts of carbon emissions, the study also studied the students' actions to reduce carbon emissions. The study attempted to measure the carbon footprint values of Polisas students based on their daily activities using the Polisas Carbon Footprint Calculator. Using data from their regular monthly activities, students may estimate their carbon footprint with the help of this simple application, which helps them gain a better awareness of their environmental effects. Important information about the attitudes and behaviours of 406 participating students regarding carbon emissions was obtained through the distribution of questionnaires to them. The respondents' data was analysed using the Statistical Package for the Social Sciences (SPSS), and the results showed an average high mean of 3.68 for attitudes towards carbon emissions and 3.60 for actions connected to lowering carbon emissions. It suggests a positive inclination among Polisas students towards environmental consciousness and sustainable practices. The findings further highlight the monthly carbon footprint of Polisas students, calculated at 3287.14 kg of CO2. To contextualize this data, the Polisas Carbon Footprint Calculator recommends planting an average of 104 plants per month, equivalent to four trees per day, to offset their carbon emissions. It gives students a tangible understanding of their carbon footprint and encourages them to actively participate in carbon offsetting initiatives actively, fostering a sense of responsibility for their environmental impact. In conclusion, this study contributes valuable insights into the awareness, attitudes, and practices of Polisas students regarding carbon footprints. The implications of this study extend to the development of targeted environmental education programs and initiatives to enhance student's understanding of their contributions to carbon emissions. Moreover, the findings underscore the potential for instituting campus-wide sustainability measures and encouraging students to actively engage in carbon offsetting activities, thereby fostering a more environmentally conscious and responsible student community at Politeknik Sultan Haji Ahmad Shah.

Changes in properties of thermal insulations under certain environmental effects

AbstractSaving energy and reducing greenhouse gas emissions is a priority for the construction sector. Heating of buildings requires the burning of fossil fuels, which can be significantly reduced by insulating the building envelope. Nowadays, the thermal insulation of buildings is essential. There are several important, well-known data about most thermal insulation materials, but there is only negligible information about the change of their properties under installation conditions or if they are already exposed to additional stresses due to structural failures and damages. This study aimed to examine the changes in properties of three common thermal insulation materials when installed in a flat roof or facade and exposed to excess moisture due to the damage of waterproofing or façade and/or when exposed to direct strong sunlight.

Transgene effects vary among maize populations with implications for improving quantitative traits

AbstractThe goal of transgenesis in plant breeding is to make step‐change improvements in traits of interest. However, improving quantitative traits, such as yield in maize (Zea mays L.), with transgenes has been difficult. Traditionally, transgene testing is done on a few isogenic lines, and results are extrapolated to entire breeding populations. Testing on limited germplasm does not provide a robust estimate of a transgene's value. Incorporating transgenes directly into breeding populations could increase genetic variance and the rate of genetic gain. Here, we used a transgene that reduces ethylene as a case study and investigated event, transgene, family, and environment effects and their interactions. We also determined whether introduction of the transgene into a breeding population would result in transgenic lines being preferentially selected over nontransgenic lines for yield. We found significant variation in transgene effects across clustered environments and families for multiple traits including yield. In environmental Cluster 2, the transgenic lines yielded 0.4 Mg ha−1 more than nontransgenic lines in family KC22; yet, in family QY43, transgenic lines yielded 0.3 Mg ha−1 less. Similarly, within Cluster 4, the QY43 family had preferential selection of transgenic over nontransgenic lines, whereas in families YE41 and AY91, nontransgenic lines were selected more frequently. These results show the critical importance of evaluating transgenes across broad germplasm diversity to assess their general value to a program. Integrating transgenes, or using gene editing, directly in a breeding program can expand genetic variation for quantitative traits and potentially accelerate genetic gain.

A Methodological Approach to the Study of Retroreflective Pavements

Climate change, principally driven by human activities, has led to an increase in global temperature, which is predicted to continue rising in the coming years. This temperature increase is even more pronounced in urban areas due to the heat island effect. This phenomenon is highly influenced by the presence of paved streets made with bituminous mixtures, which are characterised by their high solar radiation absorption capacity. Bituminous mixtures retain and re-emit a large amount of heat that intensifies the urban heat island effect. The novelty of this work is to measure retroreflective properties of bituminous mixtures that present a highly textured surface. In this context, the aim of this study is to evaluate the retroreflectance of different bituminous mixtures for use as pavement surfaces, focusing on the influence of colour and different types of aggregates. For this, total and directional reflectance measurements were conducted to determine the retroreflectance of these mixtures, with the purpose of mitigating the heat island effect in urban environments without affecting users through reflected solar radiation. The results show the retroreflective capacity of the designed mixtures within the visible spectrum, especially those manufactured with light-coloured aggregates and synthetic binders pigmented with titanium dioxide. Thus, the retroreflectance of the lighter mixtures range from 37.9% at a 0° entrance angle to 68.9% at 60°, while the black mixtures exhibit values between 5.1% and 8.4%.
