    Predicting Soil Carbon Pools in Central Iran Using Random Forest: Drivers and Uncertainty Analysis

    Shohreh Moradpour1,#, Shuai Zhao2,#, Mojgan Entezari1, Shamsollah Ayoubi3,*, Seyed Roohollah Mousavi4

    Revue Internationale de Géomatique, Vol.34, pp. 809-829, 2025, DOI:10.32604/rig.2025.069538 - 06 November 2025

    Abstract Accurate spatial prediction of soil organic carbon (SOC) and soil inorganic carbon (SIC) is vital for land management decisions. This study targets SOC/SIC mapping challenges at the watershed scale in central Iran by addressing environmental heterogeneity through a random forest (RF) model combined with bootstrapping to assess prediction uncertainty. Thirty-eight environmental variables—categorized into climatic, soil physicochemical, topographic, geomorphic, and remote sensing (RS)-based factors—were considered. Variable importance analysis (via) and partial dependence plots (PDP) identified land use, RS indices, and topography as key predictors of SOC. For SIC, soil reflectance (Bands 5 and 7, ETM+), topography, More > Graphic Abstract

    Abstract Nowadays, the use of renewable energies, especially wind, solar, and biomass, is essential as an effective solution to address global environmental and economic challenges. Therefore, the current study examines the energy-economic-environmental analysis of off-grid electricity generation systems using solar panels, wind turbines, and biomass generators in various weather conditions in Iran. Simulations over 25 years were conducted using HOMER v2.81 software, aiming to determine the potential of each region and find the lowest cost of electricity production per kWh. In the end, to identify the most suitable location, the Technique for Order Preference by Similarity… More > Graphic Abstract

    Journal of Renewable Materials, Vol.11, No.1, pp. 41-59, 2023, DOI:10.32604/jrm.2022.023151 - 10 August 2022

    Abstract The aim of this research work was to evaluate the potential of using renewable natural feedstock, i.e., Jatropha curcas oil (JCO) for the synthesis of non-isocyanate polyurethane (NIPU) resin for wood composite applications. Commercial polyurethane (PU) is synthesized through a polycondensation reaction between isocyanate and polyol. However, utilizing toxic and unsustainable isocyanates for obtaining PU could contribute to negative impacts on the environment and human health. Therefore, the development of PU from eco-friendly and sustainable resources without the isocyanate route is required. In this work, tetra-n-butyl ammonium bromide was used as the activator to open the… More > Graphic Abstract

    Abstract The epidemic outbreak COVID-19 was first detected in the Wuhan city of China and then spread worldwide. It is of great interest to the researchers for its high rate of infection spread and its significant number of fatalities. A detailed scientific analysis of this phenomenon is yet to come. However, it is of interest of governments and other responsible institutions to have the right facts and figures to take every possible necessary action such as an arrangement of the appropriate quarantine activities, estimation of the required number of places in hospitals, assessment of the level… More >

    Abstract Undoubtedly, noise has become a major hazardous issue in today’s industrial world, with a lot of people suffering from exposure to excessive noise in their work environments. This study was conducted to weigh and prioritize noise control methods in an Iranian tire manufacturing complex in Iran. The Delphi method and the Technique for Order Preference by Similarity and an Ideal Solution (TOPSIS) were utilized for this purpose. This cross-sectional, descriptive study was conducted in the baking hall of an Iranian tire manufacturing factory in 2016. To weigh and prioritize noise control methods, Analytic Hierarchy Process… More >

    Abstract ITS (Internal Transcription Spacer of nuclear ribosomal DNA) regions method was applied to identify and study the phylogenetic relationships existing between 41 individuals of Crocus, including 8 species collected in Iran (4 crop and 8 wild individuals) and 16 species (2 crop and 27 wild individuals) already registered in GenBank (NCBI). PCR amplifications were performed using the primer designed on the nucleotide sequence of nuclear region (ITS). A total of 12 sequences were obtained and registered in NCBI database. In particular, 4 of these sequences were not already present in the scientific library. Nucleotide… More >

    First report of lemon verbena crown rot caused by Phytophthora cactorum in Iran

    Moshrefi Zarandi D1, MM Aminaee2, S Rezaee3, A Sharzei4

    Phyton-International Journal of Experimental Botany, Vol.85, pp. 246-248, 2016, DOI:10.32604/phyton.2016.85.246

    Abstract Lemon verbena (Lippia citriodora) is a medicinal plant from the Verbenacea family. Its plantation and medicinal use in Iran has risen greatly in recent years. Crown and root rot symptoms were observed on this plant in some farms and greenhouses of Kerman province during November 2012. The infected plants were taken to the laboratory. Then, samples of infected root tissues were removed and were surface sterilized with 0.5% sodium hypochlorite and cultured onto CMA-PARPH medium. Based on morphological features, the isolated fungus was identified as Phytophthora cactorum. Pathogenicity test was performed using inoculated wheat seeds. To our More >

    European Cytokine Network, Vol.25, No.1, pp. 24-29, 2014, DOI:10.1684/ecn.2014.0350

    Abstract Introduction: The result of recent genome-wide association studies revealed that, in addition to HLAB27, a few non-HLAgenes are associated with susceptibility to ankylosing spondylitis (AS) in Caucasian populations. According to these studies, IL-23R is one of the genes that is associated with AS. In this study, we evaluated five important single nucleotide polymorphisms (SNPs) of the IL-23R gene which confers susceptibility to AS, and its effects on the severity of the disease in HLA-B27 positive and negative patients and several subtypes of HLA-B27. Materials and methods: The study population consisted of 294 AS patients and… More >

    European Cytokine Network, Vol.25, No.2, pp. 35-40, 2014, DOI:10.1684/ecn.2014.0352

    Abstract Background: Juvenile systemic lupus erythematosus (JSLE) is a polygenic, autoimmune disorder of unknown origin. As proinflammatory cytokines, including interleukin-6 (IL-6) and the interleukin-1 (IL-1) family, seem to contribute to the pathogenesis of JSLE, this investigation was performed to assess the associations of particular single nucleotide polymorphisms (SNPs) of IL-6 and IL-1 genes in a case-control study. Methods: Fifty nine JSLE cases were recruited for this study as the patient group, and were compared against 140 healthy, unrelated, control subjects. Using the polymerase chain reaction with the sequence-specific primer method, genotyping was carried out for the… More >
