Lean simulations provide a critical "aha moment" that helps with the understanding and buy-in of key lean principles. The purpose of this article is to share the process of development and implementation of an ongoing international on-line Lean-IPD simulation experimentation community called Administering and Playing Lean Simulations Online (APLSO). The group emerged following the arrival of the COVID-19 pandemic to include academics from 38 universities (70%) and consultant practitioners (30%). This paper documents the inception and growth of this community so that lessons learned can be shared with the international lean construction community. Serious games and simulations were transitioned to an online format, relying heavily on commonly available software such as Zoom™ and Google Slides™. The most frequently developed simulations tended to be those most typically played by academics and consultants prior to the pandemic. The authors classified games presented, as well as identified physical simulations still needing to be converted to an online format. © Prof. Luis F. Alarcón and Assoc.

This study presents a new method for assessing bacterial leaf blight (BLB) in paddy fields using multispectral UAV (Unmanned Aerial Vehicle) data through patch fragmentation analysis. Unlike traditional pixel-based methods, which often fail to capture the spatial context, our approach treats pixels as objects and analyzes their spatial relationships to evaluate BLB severity. We used six patch fragmentation metrics derived from binarized vegetation indices to classify BLB damage scores using a random forest algorithm. This method achieves high accuracy (AUC of 0.938) with a 0.5-meter sampling window, offering a more detailed assessment than conventional pixel-based analysis. This study highlights the benefits of incorporating the spatial context and improving BLB monitoring and management. This innovative approach allows agricultural stakeholders to gain valuable insights into the extent and severity of BLB disease infestation, enabling targeted intervention strategies for disease management and mitigation. © 2024, The Authors.

Since COVID-19 vaccines became available, no studies have quantified how different disaster evacuation strategies can mitigate pandemic risks in shelters. Therefore, we applied an age-structured epidemiological model, known as the Susceptible-Exposed-Infectious-Recovered (SEIR) model, to investigate to what extent different vaccine uptake levels and the Diversion protocol implemented in Taiwan decrease infections and delay pandemic peak occurrences. Taiwan’s Diversion protocol involves diverting those in self-quarantine due to exposure, thus preventing them from mingling with the general public at a congregate shelter. The Diversion protocol, combined with sufficient vaccine uptake, can decrease the maximum number of infections and delay outbreaks relative to scenarios without such strategies. When the diversion of all exposed people is not possible, or vaccine uptake is insufficient, the Diversion protocol is still valuable. Furthermore, a group of evacuees that consists primarily of a young adult population tends to experience pandemic peak occurrences sooner and have up to 180% more infections than does a majority elderly group when the Diversion protocol is implemented. However, when the Diversion protocol is not enforced, the majority elderly group suffers from up to 20% more severe cases than the majority young adult group. Copyright © 2022, The Authors.

Chromium–free conversion coatings based on Zr/Ti/Mo (ZTM) compounds via chemical conversion technology were investigated to improve the corrosion performance of SPCC-JISG 31 steels. A preliminary study was carried out to evaluate the influences of critical parameters, including the concentrations of active species Zr, Ti and Mo, and the conversion bath's pH, on the protective efficiency using a Statistical design of experiments (DoE) methodology. Passivation layer with compositional Mo, Ti and Zr elements has been employed on the steels by dipping in mixed solutions containing 17 g/l Na₂MoO₄, 1 g/l K₂TiF₆ and 7 g/l K₂ZrF₆ under pH = 5. The morphology and elemental analysis of Zr/Ti/Mo on surface of the steels was studied by the employment of scanning electron microscopy with energy dispersive spectroscopy (SEM/EDS). Pull-off adhesion test was performed, indicating that the ZTM coatings enabled to increase the adhesion strength (6.0 MPa) of mild steel to the organic coating than that of traditional phosphate (ZrP) coating. The results of electrochemical impedance spectroscopy and the salt spray test (529 h) evidenced the higher corrosion resistance of the Zr/Ti/Mo coating compared with theconventional phosphate coating. © 2024

Modeling the Regional Effects of Climate Change on Future Urban Ozone Air Quality in Tehran, Iran

arXiv 2021年

Quantifying the impact of climate change on future air quality is challenging in air quality studies. To investigate to what extent climate change can affect future summertime Ozone (O3) air quality in an urban area, the number of future exceedances of O3 air quality standards associated with regional climate change is projected by developing a statistical approach. An artificial neural network model is employed to simulate hourly O3 concentrations. The model is developed based on hourly observed values of temperature, solar radiation, nitrogen monoxide and nitrogen dioxide which are monitored during summers (June, July and August) of 2009–2012 at an urban air quality station in Tehran, Iran. Climate projections by HadCM3 GCM over the study area, driven by IPCC SRES A1B, A2 and B1 emission scenarios, are downscaled by LARS-WG5 model over the periods of 2015–2039 and 2040–2064. Further calculations are then performed to obtain future hourly temperature and solar radiation values by developing the future diurnal patterns of the variables in the study area. Future hourly O3 concentrations are then projected for five summers in each climate period. The projections are calculated by assuming that current emissions conditions of O3 precursors remain constant in the future. Therefore, only the impact of climate change on future O3 concentrations is investigated in this study. The employed O3 metrics include the number of days exceeding one-hour (1-hr) (120 ppb) and eight-hour (8-hr) (75 ppb) O3 standards and the number of days exceeding 8-hr Air Quality Index (AQI) in the study area. GCM simulations indicate that the surface temperature in the study area increases over all months of the year. The projected increases in solar radiation and decreases in precipitation in future summers along with summertime daily maximum temperature rise of about 1.2 ∘C and 3 ∘C in the first and second climate periods respectively are some indications of more favorable condition for O3 format

In this study, we compared a wide range of cell-based bioassays to the use of chemical analysis followed by exposure-activity ratio (EAR) and Toxicological Prioritization index (ToxPi) for prioritizing chemicals, sites, and hazard concerns in water samples. Surface water samples were collected from nine sites in three Central Pennsylvania streams and analyzed for a targeted list of compounds of emerging concern (CECs), including pesticides, personal care products, and pharmaceuticals. Cell-based reporter assays evaluated human and zebrafish molecular initiating events (MIEs) in endocrine and metabolic disruption, altered lipid metabolism, and oxidative stress. Bioassays showed that 29 out of 40 assays had at least one site with activity over the limit of detection. The receptors that exhibited the highest number of samples above the effect-based trigger (EBT) values that would be expected to cause toxicity were Aryl hydrocarbon receptor (AhR, human and zebrafish), Pregnane X Receptor (PXR), Estrogen Receptor-beta (ERB), and Androgen Receptor (AR). Characterizing the collection sites by their bioactivity aligned closely with the stream in which samples were collected, with the three sites in Warriors Mark Run, three in Halfmoon, and three in Spruce Run more similar than sites from the other streams. The sum of all EARs for each chemical indicated that the pharmaceutical Carbamazepine and the pesticides Carbaryl and Atrazine posed the greatest concern. However, predicted activity and site prioritization based on individual chemical analysis and calculated EAR were different than those measured by bioassay, indicating that biologically active chemicals are present in the samples that were not included in the targeted analytes. Taken together, these data show that chemical analysis and EAR analysis are beneficial for prioritization of chemicals, whereas mechanism-based bioassays are more inclusive of known as well as unknown chemical contaminants and thus of more use fo

Domestic waste from households is the biggest contributor to municipal waste management. Palangka Raya City is one of the cities that faces waste problems due to lack of awareness of the citizens. The culture of dumping garbage into river bodies is common for residents who live along the river banks. This study aims to determine waste generation and the factors affecting waste generation of household in the Palangka Raya City. The measurement of waste generation was carried out in accordance with the guidelines of SNI 19-3964-1994, while the variables that are suspected to influence the waste generation were collected by the questionnaire. To find out the factors affecting waste generation, data were analyzed by multiple linear regression. Based on the results of research conducted on 48 respondents obtained household waste generation in Palangka Raya City is 0.33 kg/person/day, while significant factors affecting waste generation are concern for the environment and income levels at a 95% confidence level and the number of family members at the 99% confidence level. While the recycling knowledge, education level, house size and installed electrical power did not significantly affect waste generation. With this information, it can be calculated the needs of TPS, the needs of the transport fleet, the needs of cleaning staff and plans for controlling household waste generation in the Palangka Raya City. © The Authors, published by EDP sciences, 2019.
