Site amplification using 1D seismic site response analysis in Islamabad: An application of building code of Pakistan 2021
Authors: Aaqib Muhammad
Published: February 2025

Abstract. This study investigates the site amplification factors in Islamabad, Pakistan, as per seismic regulations of a newly enacted Building Code of Pakistan (BCP, 2021). Using a series of 1D non-linear site response analyses, the study evaluates these factors for the Islamabad region. Nineteen representative profiles were selected from a dataset of 125 site profiles, classified according to the Code. The representative profiles were subjected to a combination of thirteen ground motions that are compatible with site class B of the BCP, 2021, and 1D nonlinear seismic site response analyses were performed. Calculated response spectra and amplification factors are compared with design estimates provided by the code spectra. The study finds that while the Code-based design spectrum aligns with the current study’s findings for periods greater than 0.5 seconds, it underpredicts the response for shorter periods for both SC and SD site classes. These findings highlight the need for a more refined approach in the seismic provisions for Islamabad to ensure accurate seismic hazard assessments and improved earthquake safety.
In-vessel aerobic composting with leachate recirculation and biochar for enhanced compost quality
Authors: Dharnaik Amit
Published: February 2025

Abstract. The increasing generation of municipal solid waste emphasizes the critical necessity for effective waste management strategies, particularly given that a significant fraction of municipal solid waste comprises biodegradable materials that are amenable to composting. The study investigated the potential impact of leachate recirculation, preheating, and biochar as a bulking agent on in-vessel aerobic composting efficiency. Four setups (T1 to T4) were tested over 30 days: T1 (control), T2 (with bulking agent), T3 (bulking agent + preheating), and T4 (bulking agent + preheating + leachate recirculation). The results revealed that T4 significantly enhanced the composting process, leading to a 45% reduction in Total Organic Carbon and a decrease in the C/N ratio from 28:1 to 17:1. Additionally, T4 maintained an optimum pH of 7.6 and moisture content of 55%, conditions favourable for microbial activity. Leachate recirculation in T4 also minimized phosphorus loss (40.75%) and potassium loss (63.31%) compared to the control. These studies show the effectiveness of integrating leachate recirculation, preheating, and biochar as bulking agents to accelerate organic matter degradation and produce nutrient-rich, stable compost.
Impact of COVID-19 lockdowns and seasonal variations on PM2.5 in Dhaka City
Authors: TUSHAR Fazlul Hoque
Published: February 2025

Abstract. The COVID-19 pandemic resulted in global lockdown measures, including in Bangladesh, which significantly affected daily life. This study evaluates the effect of the imposed lockdown measures on the air quality in Dhaka City, Bangladesh, focusing particularly on the concentrations of PM2.5. The daily average PM2.5 data from March 2016 to July 2023 were collected from air quality monitoring instruments at the U.S. Consulate in Dhaka. We analyzed PM2.5 concentrations during pre-lockdown, lockdown, and post-lockdown periods and seasonal variations from 2016 to 2023. Our study showed that the mean concentration of PM2.5 had a reduction of 14.78% during the 2020 lockdown in comparison to the values found in 2019. However, there was an increase in levels of PM2.5 in subsequent years, with mean concentrations increasing by 15.48% in 2021, 24% in 2022, and 38.71% in 2023 from the 2020 levels. Seasonal analysis showed that the winter season had the highest levels of PM2.5, which can be caused by less rainfall, and an increase in brick kiln activity. The lowest levels occur during the monsoon season due to heavy rainfall, higher wind speeds, and higher relative humidity. These findings assist decision-makers in formulating effective policies to reduce PM2.5 pollution by considering vehicular, industrial, and construction activities, and meteorological factors.
Critical building components analysis: An empirical study
Authors: Chowdhury S.R.
Published: February 2025

Abstract. To improve a building's performance, it is essential to critically evaluate the common structural component failures and damages encountered by construction professionals throughout a building’s service life. This study aims to identify and prioritize key building components, as well as critical defects and their underlying causes, in construction projects. After reviewing the relevant literature, 23 building assessment reports were analyzed using descriptive statistical methods. The results show that walls are the most affected component, followed by slabs, foundations, columns, beams, joints, and staircases. The most common defects include small or hairline cracks, reinforcement corrosion, concrete spalling, differential settlement, tilting, efflorescence, and seepage in walls and slabs. These issues are primarily attributed to poor planning, inadequate or absent subsurface investigations, low-quality materials, substandard workmanship, increased live loads due to changes in building use, aging structures, and insufficient concrete cover. The findings offer valuable insights for key stakeholders—such as project owners, consultants, contractors, as well as academic and industry professionals—by helping to reduce building defects and raise the standards of building performance throughout their service life.
A green-magnetic approach to textile wastewater decolorization using nickel ferrite-enhanced activated carbon from pistachio shells
Authors: HASSAN Raouf
Published: February 2025

Abstract. In the pursuit of eco-friendly solutions for textile wastewater treatment, this study presents a green magnetic adsorbent material synthesized from pistachio shell-derived activated carbon-supported by modified nickel ferrite (NiFe2O4/AC). The research explores the material's structural, morphological, and chemical properties through a comprehensive characterization including XRD, TEM, and SEM. XRD analysis confirmed the crystalline structure of the nickel ferrite nanoparticles with an average crystallite size of 12.4 nm. TEM and SEM images revealed a uniform distribution of nanoparticles on the porous activated carbon matrix, which is critical for maximizing the adsorptive capacity and facilitating magnetic separation. These structural features contribute to the composite's high adsorption efficiency and recyclability. The adsorption performance is evaluated using various parameters including pH, adsorbent dosage, contact time, and stirring rate, and the results demonstrate its efficacy in removing colorants from textile wastewater. The NiFe2O4/AC magnetic nanocomposite exhibits remarkable adsorption abilities, leading to the complete decolorization of textile wastewater when utilized under optimal conditions, including a pH of 9, a contact time of 60 min, an adsorbent dosage of 0.8 gm, and a stirring rate of 150 rpm. This innovative green adsorbent holds great promise as an environmentally responsible and cost-effective solution for the textile industry's wastewater treatment needs. Its unique combination of renewable raw materials and advanced adsorption properties represents a significant step toward sustainable water purification and pollution control.

Published: February 2025

Background

The impact of adverse childhood experiences (ACEs) has been the focus of most studies for the past decade. There is an indication that developing resilience can help youth overcome these ACEs.

Objective

This article presents a study protocol for a randomized controlled trial (RCT) to investigate the effects of a resilience-building intervention on psychological well-being, coping strategies, stress, quality of life, resilience, resource finding, and resilience among individuals affected with ACEs in Malaysia.

Methods

The is a 2-armed, single-blind, RCT, whereby 50 participants (25 in each group) with ACEs will be randomly assigned to intervention and control groups. The former will be exposed to a resilience-building program (R2), which entails a multisystemic approach to resilience and recognizes the importance of rugged qualities and access to resources among individuals affected with ACEs. The intervention will be delivered via internet-based by a facilitator and broadly divided into 5 sessions, focusing on self-exploration and social support, coping techniques and coping skills, resource finding, spirituality, and resilience building. Meanwhile, the control group participants will not receive any form of intervention. Saliva samples will also be collected from both groups and assessed for salivary cortisol levels. Outcome measures will be assessed during baseline and postintervention using validated instruments. Another follow-up measurement will be conducted 4 weeks later.

Results

The clinical trial has been registered with the Australia New Zealand Clinical Trials Registry. Ethical approval was obtained from the Research Ethics Board at the National University of Malaysia (UKM PPI/111/8/JEP-2021-894). A total of 28 participants have been recruited to the RCT Participant recruitment will be completed by January 2025. The final analysis will be conducted by March 2025.

Conclusions

This is among the first studies to provide evidence in the context of RCTs for resilience-building intervention that combines self-report and physiological measures (ie, saliva and heart blood pressure) among individuals with ACEs. The findings will assist relevant authorities in the health and policy sectors to develop effective strategies for addressing the negative impacts of ACEs on the vulnerable population in Malaysia.

Identifying Misinformation About Unproven Cancer Treatments on Social Media Using User-Friendly Linguistic Characteristics: Content Analysis
Authors: Fridman Ilona , Boyles Dahlia , Chheda Ria , Baldwin-SoRelle Carrie , Smith Angela B , Elston Lafata Jennifer
Published: February 2025

Background

Health misinformation, prevalent in social media, poses a significant threat to individuals, particularly those dealing with serious illnesses such as cancer. The current recommendations for users on how to avoid cancer misinformation are challenging because they require users to have research skills.

Objective

This study addresses this problem by identifying user-friendly characteristics of misinformation that could be easily observed by users to help them flag misinformation on social media.

Methods

Using a structured review of the literature on algorithmic misinformation detection across political, social, and computer science, we assembled linguistic characteristics associated with misinformation. We then collected datasets by mining X (previously known as Twitter) posts using keywords related to unproven cancer therapies and cancer center usernames. This search, coupled with manual labeling, allowed us to create a dataset with misinformation and 2 control datasets. We used natural language processing to model linguistic characteristics within these datasets. Two experiments with 2 control datasets used predictive modeling and Lasso regression to evaluate the effectiveness of linguistic characteristics in identifying misinformation.

Results

User-friendly linguistic characteristics were extracted from 88 papers. The short-listed characteristics did not yield optimal results in the first experiment but predicted misinformation with an accuracy of 73% in the second experiment, in which posts with misinformation were compared with posts from health care systems. The linguistic characteristics that consistently negatively predicted misinformation included tentative language, location, URLs, and hashtags, while numbers, absolute language, and certainty expressions consistently predicted misinformation positively.

Conclusions

This analysis resulted in user-friendly recommendations, such as exercising caution when encountering social media posts featuring unwavering assurances or specific numbers lacking references. Future studies should test the efficacy of the recommendations among information users.

Published: February 2025

BACKGROUND

In 2022, 54% of people with HIV were aged 50 and older, yet clinical care for HIV often falls short of comprehensively integrating care for aging-related conditions. In response, the Health Resources and Services Administration’s HIV/AIDS Bureau’s Ryan White HIV/AIDS Program (RWHAP) funded a new initiative comprised of 10 demonstration sites to test emerging interventions to support persons aging with HIV, as well as a capacity-building provider and an evaluation provider. NORC at the University of Chicago received the award for the evaluation provider.

OBJECTIVE

The purpose of this article is to describe application of the HRSA HAB Implementation Science Framework to a multi-site evaluation, evaluation protocol, technical assistance to support evaluation, and the initiative’s dissemination plan.

METHODS

Using a theory-based approach, NORC developed a mixed-methods evaluation plan using an implementation science Hybrid Study Type 2 with two main aims: 1) describe implementation outcomes, and 2) assess client-level outcomes. Implementation outcomes were assessed at an organizational-level using tools including a survey of site characteristics, key informant interviews, documentation of monthly monitoring calls, and costs. Client-level outcomes were assessed through a survey and medical chart abstraction tool. NORC also collects data on sites’ engagement with the capacity-building provider and their satisfaction with services provided.

RESULTS

Organizational-level data collection began upon Institutional Review Board (IRB) approval on April 6, 2023. All sites were enrolling clients into the intervention and evaluation by September 2023. Analysis of baseline results is currently underway, and comprehensive findings are expected by late 2025.

CONCLUSIONS

To our knowledge, this is the first national study to evaluate emerging interventions for persons aging with HIV using implementation science. The findings will build the evidence base for advancing HIV clinical care to meet the needs of an aging population.

Until recently, the agro-industrial complex of the Russian Federation tended to lag behind foreign countries due to the lack of proper mechanization of work. After all, a significant part of the
work in rural areas is often occupied by loading and unloading operations during transportation of
various goods. Therefore, in order to improve productivity of the performance of the above works it
is necessary to use specialized equipment. Such equipment includes a hydraulic lift mounted on the
chassis of road construction and agricultural machines. The article considers the existing variants of
domestic and foreign devices. However, high price is the main problem of these devices, so often in
order to perform loading/unloading operations one has to use homemade equipment designs. The
article discusses the options of lifts installed on the tractor MTZ-80 (MTZ-82) – one of the most
common machines in rural areas. The following options are proposed - simplified version with a fixed
boom and the version with a «hinge-type» boom. During the work, positive and negative aspects of
each of the proposed designs, especially their operation features, were identified. Individual cargoaltitude characteristics were determined for each type. The article considers the possibilities of connection of hydraulic system fittings to regular system of the tractor without its change. Also, we considered the possibility of the machine roll-over with the installed new equipment and made conclusions that the MTZ-80 tractor was not inclined to roll-over when the above devices were installed.
We came to the conclusion confirming the feasibility of using these devices in practice in the agroindustrial complex of the Russian Federation.

Animal husbandry is an important part of the Russian agro-industrial complex. For its
development, various feed additives are being developed, including probiotic ones, which have a positive effect on both productivity and animal health. Probiotic additives consist of living microorganisms that do not die when they enter the gastrointestinal tract, but retain their viability and actively
participate in the process of digestion. Bacteria of the genus Bacillus, widely used in the creation of
probiotic additives, through the synthesis of pectolytic, proteolytic enzymes, contribute to the normalization of digestion, produce nonessential amino acids and essential amino acids, such as threonine, glutamic acid, alanine, valine, tyrosine, histidine. In addition, these bacteria stimulate the body's
immunity, have anti-allergenic and antitoxic effects, and also exhibit antitumor activity. This article
examines the influence of factors such as cultivation temperature and active acidity of the medium
on the development of probiotic culture of Bacillus subtilis. Our goal was to experimentally determine
the optimal values of temperature and acidity for the cultivation of microorganisms. To determine the
optimal level of acidity, 4 experiments were conducted with a pH equal to 6, 7, 8, 9, and to determine
the most suitable temperature, 5 experiments were conducted with 37, 25, 30, 33.5, 40. So, as a result
of experiments conducted at the Far East Research Institute of Mechanization and Electrification of
Agriculture in the years 2018-19, it was found that an increase in the cultivation temperature up to
ͶͲˑС and the pH of the medium up to 8 had positive effect on the growth dynamics of the bacterium
Bacillus subtilis.

Published: February 2025

Objective

We investigated the association between historic redlining and risk of gestational diabetes (GDM), and if this relationship is mediated by maternal obesity and area-level deprivation.

Research design and methods

This retrospective study included 86,834 singleton pregnancies from Kaiser Permanente Southern California’s (KPSC) health records (2008–2018). Redlining was assessed using digitized Home Owners' Loan Corporation (HOLC) maps, with patient’s residential addresses geocoded and assigned HOLC grades (A,B,C,D) based on their geographic location within HOLC-graded zones. For GDM cases, exposure was assigned based on address at diagnosis date; for non-cases, it was assigned based on address during the 24th–28th gestational week. Health records were combined with area deprivation index (ADI) from 2011–2015 census data. Mixed-effect logistic regression models assessed associations between redlining and GDM, with mediation by BMI and ADI evaluated using inverse odds ratio weighting. Models were adjusted for maternal age, education, race and ethnicity, neighborhood level income, and smoking status.

Results

Among the 10,134 (11.67%) GDM cases, we found increased risk of GDM in B ("Still desirable," adjusted odds ratio [aOR] 1.20, 95% confidence interval [CI] 0.99-1.44), C ("Definitely declining," aOR 1.22, 95% CI 1.02-1.47), and D ("Hazardous, i.e., redlined," aOR 1.30, 95% CI 1.08-1.57) graded neighborhoods compared to the "Best" graded zone. Pre-pregnancy BMI and ADI mediated 44.2%, and 64.5% of the increased GDM risk among mothers in redlined areas.

Conclusions

Historic redlining is associated with an increased risk of GDM, mediated by maternal obesity and neighborhood deprivation. Future research is needed to explore the complex pathways linking redlining to pregnancy outcomes.

Published: February 2025

Atopic dermatitis is a chronic skin disease affecting quality of life, sleep, and mental health. Traditional evaluation methods focus on clinical assessments, but there is a growing need for tools that incorporate patient-reported outcomes (PROs). To evaluate the effectiveness of the Atopic Dermatitis Control Tool (ADCT) in assessing disease severity in patients with moderate to severe atopic dermatitis and to compare the efficacy of systemic immunosuppressants and dupilumab in patients with moderate to severe atopic dermatitis. A prospective, observational study was conducted across seven centres in Korea, involving 112 patients with moderate to severe atopic dermatitis. The ADCT, Eczema Area and Severity Index (EASI), and Dermatology Life Quality Index (DLQI) were used for assessing atopic dermatitis severity. In addition, the study assessed the effectiveness of immunosuppressants and dupilumab over the course of one year. The study found significant correlations between ADCT scores and other severity measures (EASI, DLQI). The correlation coefficients were 0.54 (p < 0.0001) for ADCT vs EASI and 0.83 (p < 0.0001) for ADCT vs DLQI. Furthermore, patients treated with dupilumab exhibited greater improvement compared with those on cyclosporine, as measured by the ADCT (adjusted OR [95% CI]); 6.98 [2.49, 19.58]). The ADCT effectively captures subjective aspects compared with the EASI and can be used practically and effectively in clinical settings of atopic dermatitis.

Teacher job satisfaction is crucial in supporting the achievement of individual and organizational performance in education. However, in the context of education in Indonesia, there is a lack of research specifically exploring how school climate affects teacher job satisfaction, particularly considering the role of self-efficacy and work engagement as mediating variables. This study aims to analyze the mediating role of self-efficacy and work engagement in the relationship between school climate and teacher job satisfaction. The study uses a cross-sectional survey design involving 208 senior high school teachers (44.13% male, 59.13% female; average age = 37.96, SD = 8.34). Data were collected using the Minnesota Satisfaction Questionnaire (MSQ), School Climate Survey, Teachers’ Self-Efficacy Scale, and Utrecht Work Engagement Shortened Version (UWES-9). Data analysis was conducted using Structural Equation Modelling - Partial Least Squares (SEM-PLS) to test the hypotheses. The results indicate that school climate significantly influences teacher job satisfaction through the mediation of self-efficacy. Furthermore, work engagement also serves as a significant mediator in this relationship. These findings contribute to efforts to enhance teacher job satisfaction, showing that a positive school climate can foster improvements in self-efficacy and work engagement, which, in turn, enhances teacher job satisfaction. Therefore, it is essential to create a supportive school climate to improve teachers' overall well-being.
