The photocatalytic reduction of hexavalent chromium (Cr(VI)) using ZnO nanorods immobilized on kaolin clay was studied. Scanning electron microscopy (SEM) and Fourier transform infrared (FT-IR) analysis demonstrated favorable immobilization onto the kaolin. efficiency UV/ZnO/kaolin process for Cr(VI) about 88.0%, which more effective than UV/ZnO (43.7%). increased from 35.7 to 97.1%, with increasing photocatalyst dosage 0.25 3 g/L, respectively. reaction rate constant (kobs) decreased 0.0769...
Abstract Background With the unprecedented expansion of COVID-19 in world since December 2019, Iran’s health system, like other countries, faced various challenges managing disease, which led to numerous experiences and lessons learned. This study was conducted identify these regarding unique political, economic, cultural issues, could help countries with similar situations. Methods The present performed using a qualitative multi-method approach content analysis method. data were collected...
Abstract The effect of dissolved oxygen on the photocatalytic reduction Cr(VI) with illuminated TiO2 was studied in this work variation solution pH, contact time, and initial concentration. Oxygen or nitrogen gas used as a purging gas. Overall, removal efficiency decreased pH increased. by UV/TiO2 increased decreasing because potential difference between conduction band Cr(VI)/Cr(III) well anionic-type adsorption onto surface. compared to that less competition reaction electron TiO2. pattern...
Challenges of Social Trust in Disaster Management Focusing on COVID-19 Iran: Recommendations for Gaining it Again
The incidence of kidney stones has been rising globally, particularly among the elderly. This study aims to determine prevalence and its associated factors in Iran. cross-sectional was conducted using data collected first phase Ardakan Cohort Study on individuals aged 50 years above, Yazd province, Baseline a comprehensive checklist stone occurrence ascertained through participants' self-reported response question "Have you ever diagnosed with stones?" Logistic regression analysis used due...
Quantitative and qualitative evaluations of the publication trends architecture can be useful for guiding future research agendas both researchers journals. This study aimed to investigate bibliometric characteristics emergency medicine (EM) researches across different journal quartiles. A systematic search was conducted in Scopus database retrieve published documents from journals Q1 Q4 categories (based on Scimago Journal Ranking) inception April 2024. The analyses were carried out using...
Introduction: Nowadays, noise pollution in the environment has become as a worldwide health concern. A large share of this comes from vehicles, where mufflers their exhaust systems are essential for lowering engine levels. Proper muffler design and modifications to its geometric parameters, including adding holes baffle changing orientation, can significantly influence acoustic performance contribute effective enhanced reduction. Materials Methods: The finite element numerical method was...
In this work, removal of phenol from aqueous solutions by activated red mud was investigated. Scanning electron microscopy and energy dispersive X-ray spectroscopy used to observe the morphology surface components mud, respectively. The effects various parameters on efficiency were studied, such as contact time, pH, initial concentration, adsorbent dosage. percentage initially increased, solution pH increased 3 7, then decreased above neutral pH. increasing concentrations. Adsorption results...
Acceptance and willingness to receive the vaccine are among main factors in success or failure of a health system implementing vaccination program. The present study was conducted Tehran, political economic capital Iran, determine acceptance COVID-19 identify its associated factors, explain most important barriers strategies for vaccination. This research concurrent quantitative qualitative mixed-method study. In part, 1200 individuals aged more than 18 years were selected from households 22...
Background Disasters are considered one of the major threats to health communities. Given global spread disasters, there has been a renewed emphasis in recent years on using community participation approaches disaster risk management. Community field emergency and Low Middle-income countries faces lot challenges. Objective The objective this study is explore specific challenges faced by communities Iran concerning their Methods In study, qualitative content analysis as research methodology...
Effect of different type organic compounds (humic acid, oxalate, ethylenediaminetetraacetic nitrilotriacetic phenol) on the photocatalytic removal cyanide with TiO2 or ZnO was studied in this work variation solution pH, contact time, initial concentration and compounds. Photocatalytic oxidation efficiency greatly affected by pH. It increased as pH decreased. Also maximum observed near at neutral because reduced activity exceedingly low high values originated from either acidic/photochemical...
