This systematic review has been undertaken in order to assess the effects of hypocaloric, high-protein diets on weight loss and cardiovascular risk factors such as serum lipid levels in metabolically healthy obese adults. The primary outcomes measured include changes in pre- and post- diet mean BMI, LDL-C, HDL-C, TAG, and TC levels. 

Four databases including: Embase, MEDLINE (via PubMed), Cochrane and Web of Science were searched with no restrictions on language or publication period. Clinicaltrials.gov was also searched in order to identify unpublished or on-going studies.

Three of four studies included in this systematic review noted a significantly greater loss in pre- and post- diet mean BMI levels in the hypocaloric, high-protein diet group as compared to hypocaloric, non-high protein diets (control). Whilst pre- and post-diet mean LDL-C, HDL-C, TAG, and TC levels did not differ significantly among hypocaloric, high-protein and control diet groups.

Hypocaloric, high-protein diets had an unclear effect on blood-lipid levels as compared to control. Weight loss however was significantly greater in the hypocaloric, high-protein group as compared to other hypocaloric, non-high-protein diet groups.

Free vibration analysis of Kagome lattice cylindrical shells is presented using an improved equivalent stiffness matrix model. The boundary conditions of the shell are simply supported and the classical thin shell theory is considered to obtain the equations of motion. The modified equivalent stiffness matrix of the lattice shell is extracted by collecting stiffness matrix of a simple shell and those of grid-reinforced shell according to their volume fractions. The equations of motion are derived using the Hamilton’s principle as well as the Flugge thin shell theory and then are solved by the Navier type solution. The present results are compared by those obtained by a finite element analysis (FEA) in Abaqus software. Comparison results report good accuracy of the present method in comparison with those obtained by the FEA. Finally, effects of various parameters such as shell thickness, width and length of the grids and mode number on the natural frequencies of Kagome lattice cylindrical shell are investigated. The novelty of this paper is using the Flugge shell theory as well as a modified equivalent stiffness matrix for vibration analysis of Kagome lattice shell.

 Statin therapy is widely used for the management of dyslipidemia and the prevention of cardiovascular diseases (CVDs). However, there is a growing concern about its potential effects on bone metabolism markers and mineral density. The aim of this systematic review and meta-analysis was to investigate the effect of statin therapy on these parameters.

 PubMed/MEDLINE, Scopus, and Clarivate Analytics Web of Science databases were searched from inception to August 2023, using MESH terms and keywords.

 After screening 2450 articles, 16 studies that met the inclusion criteria were included, of which 12 randomized controlled trials (RCTs) were used for meta-analysis. The findings showed that statin therapy significantly reduced bone-specific alkaline phosphatase (B-ALP) levels (WMD=-1.1 U/L; 95% CI -2.2 to -0.07; P=0.03; I2=0%,), and bone mineral density (BMD) at different sites (WMD=-0.06 g/cm2 ; 95% CI -0.08 to -0.04; P<0.001; I2=97.7%, P<0.001). However, this treatment did not have a significant effect on osteocalcin, serum C-terminal peptide of type I collagen (S-CTx), serum N-telopeptides of type I collagen (NTx) concentration, or overall fracture risk.

 This systematic review and meta-analysis provide evidence that statin therapy is associated with a significant reduction in B-ALP levels and BMD at different sites of the skeleton. Further studies are needed to investigate the long-term effects of statin therapy on bone health and to identify the potential underlying mechanisms.

Considering the challenges related to ethnic and cultural diversity in Iranian society and the consequences thereof, the present study analyzes the elements and messages representing ethnic identity-seeking on Instagram pages. The primary research question is: What are the main messages, features, and symbols of ethnic nationalism employed by Turkish identity-seekers on Instagram? This study employs semiotics and qualitative content analysis methodologies. The study population comprises Instagram pages of ethnic identity-seekers, with a sample of four selected images chosen purposively from Instagram pages during Fall 2021. The selected images were analyzed using Saussure's semiotic perspectives, Peirce's semiotic elements, and Roland Barthes's explicit and implicit connotations. The qualitative content analysis included Castells' theory of identity, Smith’s ethnic nationalism intensity, and persuasive techniques and appeals. Findings indicate that the recurring use of symbols associated with Turkish ethnicity in the analyzed images generally signifies a Pan-Turkic identity, advocating for an independent state for Turkish-speaking peoples worldwide. Iconic signs such as the "Grey Wolf," the wolf hand gesture, the Turkish and Azerbaijani flags, and historical figures like Babak Khorramdin, Oghuz Khan, and Tomyris—symbols of Azerbaijani mythology—are prominently featured. Ethnic demands are also articulated using cultural elements such as football, employing emotional, logical, and nostalgic appeals to capture audience attention.

The conservation of species depends on the protection of their natural habitats, and this is possible with a more detailed analysis of habitats (15, 31). In this regard, habitat suitability modeling is a scientific and practical solution to estimate the distribution range of species (12). Modeling allows ecologists and wildlife experts to gain knowledge about the ecological needs of species, barriers and factors limiting their distribution, predicting the effects of climate change, habitat destruction, and species invasion. One of the most widely used and best methods for modeling the habitat suitability of species that only uses presence data is the maximum entropy (MaxEnt) method (24). Studying the habitats of all species on a large scale is challenging due to budget and time limitations. It is imperative to direct the limited budgets and efforts towards conservation of greater ecological significance or at greater risk. The Persian Gazelle, Gazella bennettii shikarii, is an important hereditary mammal species that is part of the Bovidae family and the antlope subfamily. It can be found in India, Pakistan, southern Afghanistan, and Iran. In Iran, Persian gazelle prefers dry and very dry plains with an average annual rainfall of 50-250 mm and usually hills (2). Several studies conducted on the habitat suitability of this species in Iran protected areas including Kavir national park (18), Naybandan wildlife refuge (3) and Copper Ore Protected Area (22). To conduct a more comprehensive analysis of meta populations, we need to address the gaps in the distribution and habitat requirements of this species in peripheral areas, including the study area. The present study aims to evaluate the suitability of existing habitats and to identify the potential habitats of Persian gazelle (Gazella bennettii) in Hormod protected area using the MaxEnt method, so that its results can be used for better conservation and management of this species meta populations.

Study area: Hormod protected area with an area of ​​208,731 hectares located in southeast of Fars province, Iran (Fig.1). Most important threat factors of this area, are the droughts, illegal hunting, illegal grazing, crossing the area by Shiraz-Bandar Abbas Road, agriculture and harvesting edible mushrooms by local peoples.Recording species presence points: during the extensive field visits in different seasons of 2022-23, along the specific routes of the plain and hilly areas as the actual habitats of the species, using a Global Positioning System (GPS) 45 presence points was recorded (Fig. 1).Environmental data: based on the literature review, four groups of environmental variables including climatic factors (Tables 1 and 2), vegetation cover, topographical factors (slope, aspect and elevation) and human factors (distance from the village, water sources, road, agricultural lands and environmental checkpoints) which are effective in determining the habitat suitability of this species were used in the modeling.Modeling: Species presence points were converted into digital layers in ArcGIS 10.3 software, then these presence points were considered as dependent variables and selected environmental data (layers) as independent variables. To run the model, 10,000 background points and a maximum of 15 repetitions were considered. Also, 70% of presence points were used to build the model and the remaining 30% were used to evaluate the modeling results.Model evaluation: In this study, the area under the curve (AUC) of the receiver operating characteristic (ROC) was used to check the validity of the results obtained from the model, which is one of the most common methods for evaluating predictive models (8). Jackknife test was also used to determine the importance of each environmental variable in predicting the suitability of the habitat of the species.

Habitat desirability: According to the results, about 36746 hectares equivalent to 17.6% of Hormod protected area is considered as a suitable habitat and about 171985 hectares equivalent to 82.4% is an unsuitable habitat for the Persian gazelle (Fig. 2).Model evaluation: In this study, the value of the area under the curve (AUC) calculated equal to 0.87, that indicates the “very good” predictive performance of the model (20) (Fig. 3).The participation of variables in model: in Hormod protected area, the variables of distance from the villages, vegetation cover, slope and average daily temperature with 41.1, 16.6, 13.7 and 10.3 percent of influence are the most important variables affecting the suitability of Persian gazelle habitat, respectively (Fig. 4). However, according to the jackknife test, the average daily temperature variable has the highest power to predict the suitability of the Persian gazelle habitat in the Hormod protected areas (Fig. 5), in the other words by removing this variable, the predictive power of the model decreases more than removing any other variables.Species response curves: Finally, the response curves of the species to the four main environmental variables that affect its habitat suitability were examined (Fig. 6).

In this study, the habitat suitability of Persian gazelle was mapped within the protected area of ​​Hormod using MaxEnt software. The suitable habitats of species are located in the northern and northeastern parts of the study area, which have the greatest distance from human factors, especially villages. The distance from the village has the most importance on the desirability of Persian gazelle habitat in the study area. Based on the results, with increasing the distance from the village, the habitat desirability for Persian gazelle increases. According to the response curves, with an increase in the distance of 10 km from the village, the habitat suitability for the species increases. It seems that moving away from the village in order to find a shelter to prevent hunting is very important as one of the parameters of habitat selection in terms of the species of Persian gazelle in the study area. In a study conducted in the southern regions of Tunisia on Gazella dorcas (5), it was found that human variables and especially the distance from agricultural lands were the most important factors shaping the distribution pattern of this species. Also, the study conducted on the condition of the gazelle (Gazella cuvieri) habitat in North Africa (14) also showed that the presence and distribution of this species is affected by the increasing distance from human settlements and areas with low human population density. The results of the present study showed that vegetation plays a role as the second most important factor in the desirability of the habitat of this species, and the highest presence of the species is in the type of salt desert rangeland (Salsola tomentosa). In similar studies, the importance of vegetation in the desirability of the habitats of Persian Gazelle and other wildlife species has also been confirmed (13, 18, 19, 29). Considering the drastic decrease in the population size and the range of distribution of the Persian gazelle in Iran (3) and that this type of prey is used by important carnivores such as leopards and cheetahs, we suggest to preventing the habitat destruction and proper protection of the suitable habitat of this species in the study area.

Pandemics pose significant threats to global health systems, as exemplified by COVID-19, which placed unprecedented strain on healthcare infrastructures worldwide. One innovative solution that emerged during this crisis was the use of multifunctional centers. These facilities, capable of rapid conversion for various healthcare services, played a crucial role in alleviating pressure on hospitals. In Iran, the Iran Mall Convalescent Center demonstrated the effectiveness of such centers by converting into the country’s largest vaccination hub. This paper explores the importance and benefits of multifunctional centers in managing future pandemics. Multifunctional centers offer reduced pressure on hospitals, cost-effective and rapid setup, flexibility in services, optimized resource use, and increased healthcare system resilience. However, challenges include the need for rapid adaptation, specialized training, and coordination among various stakeholders. The Iran Mall Convalescent Center’s successful operation highlights the potential of multifunctional centers to enhance pandemic preparedness and response.

Using different algorithms to extract, describe, and match features requires knowing their capabilities and weaknesses in various applications. Therefore, it is a basic need to evaluate algorithms and understand their performance and characteristics in various applications. In this article, classical local feature extraction and description algorithms for large-scale satellite image matching are discussed. Eight algorithms, SIFT, SURF, MINEIGEN, MSER, HARRIS, FAST, BRISK, and KAZE, have been implemented, and the results of their evaluation and comparison have been presented on two types of satellite images. In previous studies, comparisons have been made between local feature algorithms for satellite image matching. However, the difference between the comparison of algorithms in this article and the previous comparisons is in the type of images used, which both reference and query images are large-scale, and the query image covers a small part of the reference image. The experiments were conducted in three criteria: time, repeatability, and accuracy. The results showed that the fastest algorithm was Surf, and in terms of repeatability and accuracy, Surf and Kaze got the first rank, respectively.

Among the most important and basic requirements of good social governance, in order to control and reduce social problems and damages in the development process; Drafting and approving laws and adopting correct policies. Therefore, in the development programs of the whole country, the eyes of experts and legislators, paying attention to social issues (apart from the way of implementation and effectiveness of adopted policies) has always had a special place. Therefore, in this article, we are going to answer the question of how far the legislator has been able to control and reduce the social harms that were previously in the relevant provisions of the laws of the fourth, fifth and sixth programs, with reference to the library method and analytical description. Because, the solutions to improve the governance capacity in the field of effectively dealing with social problems and harms are by emphasizing the rules and indicators necessary for the formulation of high-quality legal rulings in this field. Because the low quality of legal rulings and non-compliance with the principles of law writing, despite the allocation of resources and provision of executive facilities, hinders the effectiveness of actions and the realization of the legislator's intentions. In terms of control criteria, amend and complete the explained development in the law of the 7th development plan and provide the necessary points for advanced policies accordingly. Therefore, with regard to 6 components or basic elements of priority, strategy, solution, implementer, indicator and finally the implementation guarantee, the implementation of the laws was discussed and finally the findings of the article indicated that the legislator by implementing the aforementioned levels in the laws of the previous development program And with a little modification, it has had a stability-oriented approach.

Quercetin (Qu) is a type of plant flavonoid that is beneficial in fighting prostate hyperplasia cells. ‎Meanwhile, Nigella sativa seed oil (NSO) has shown promise in relieving benign prostatic ‎hyperplasia (BPH) symptoms. This study aims to assess the effects of Qu combined with NSO-‎based nanoemulsion (Qu-NSO) against a rat model of BPH. The study involved the ‎induction of ‎BPH in rats using testosterone enanthate (5 mg/kg) subcutaneously and ‎administering different ‎treatments, ‎including Qu (25 mg/kg and 50 mg/kg), NSO, and Qu-NSO (25 mg/kg and 50 ‎mg/kg), with total volume 0.5 ml per oral to assess the effects of ‎Qu-NSO. NSO, coconut oil, ‎Tween 80, and polyethylene glycol 400 (PEG) were obtained for the ‎self-nano-emulsified drug ‎delivery system. The globule size and zeta potential of formed vesicles were measured. ‎Dihydrotestosterone (DHT), prostate-specific antigen (PSA), prostatic weight and index, oxidant ‎and antioxidant markers, and histopathology were investigated in the rat model. The average ‎globule size for Qu-NSO was ‎171.9 ± 10.9 ‎nm, with ‎a zeta potential value of ‎+17.3 mV.

Qu-NSO was superior to the finasteride group in decreasing ‎prostatic weight and antioxidative ‎properties, such as increasing antioxidant enzyme ‎activity.‎ ‎This study revealed that the Qu and NSO in a Qu NSO formula enhanced the Qu efficacy in ‎managing BPH.‎

In this article, the method of relating the dimensional parameters of the klystron tube resonator cavity to one of its parameters and then analyzing the cavity using this parameter is discussed. This new method makes it much easier to design and optimize the resonator. This method has been used to design a cavity for 3GHz frequency, so that after specifying a general parameter of the cavity and making other dimensions depend on it, and then using the sweep of this geometric parameter to check the changes in the electrical parameters of the design of the RF section including the resonance frequency , M and R/Q and then the effects on the output efficiency of the klystron tube has been studied using Mathematica and Microwave Studio CST software.

Environmental noise, caused by traffic, leads to increased risk of health problems. Nowadays, noise pollution is one of the most important problems in the communities which adversely affects the health. The aim of this study was to assess the noise pollution in Khorramabad city.

To measure the noise level in the city, 39 stations near to sensitive places such as hospitals, educational centers, and so on were selected. Measurements were performed, for 30 min, in the mornings (7-10 AM) and evenings (5-8 PM) using a standard sound level meter. The measurements were made on working days during the week and assuming the traffic load was the same.

The sound level in all 39 considered stations was higher than the standard of residential-commercial in more than 90% of the stations compared to the environmental standard. The mean of sound measured in the monitored stations was equal to 68.28±2.6 dB. The maximum measured sound level belonged to station S2. In station S2, the maximum measured sound was reported as 81.72±11.3 dB. The findings showed that sound level in the evenings were slightly higher than the mornings. Also, in the evening, the highest and lowest measured sound values belonged to stations S1 and S20. The amount of measured sound level at stations S1 and S20 was equal to 80.9 and 39.7 dB, respectively. Based on findings, the highest and lowest sound recorded belonged to stations S39 and S20 which area type of stations S20 and S39 was commercial and residential, respectively.

This study showed that the average level of sound pressure was higher than the permissible limit, so the necessity of planning is suggested to reduce the level of noise pollution and consequently reduce the anxiety level of citizens and increase health.

In judicial divorce, when a couple is neither satisfied nor divorced, the religious judge divorces the wife for specific reason and at the wife's request. What is important in the context of divorce is its nature, because it has different effects depending on that nature. The issue of divorce is controversial. A group believes that it is reciprocal while the other group holds a different perspective, asserting that each of these views has important and fundamental issues. In this article, by expressing the right to refer to the reform of the divorce, the problem of redressing the divorce is resolved and there is no violation of the rule of divorce. The present article reviews the contents of verses 228, 229 and 231 of Surah Baqarah, criticizing the viewpoint of the well-known jurisprudent that argues that the will of reform is not a condition. It also examines the various views on this matter, and finally, affirms the existence of this condition as necessary for the referral.

Recurrent aphthous stomatitis or RAS is one of the most common lesions of the oral mucosa, which is recurrent and painful. So far, several factors have been known as predisposing factors to this disease. However, there is no specific treatment for it. Anxiety and stress are among the causes of these lesions. Quality of life reflects the level of satisfaction and sense of well-being in individuals. Since it is believed that these lesions affect the quality of life due to their chronic and painful nature, the present study aimed to evaluate the quality of life of patients with recurrent oral aphthous stomatitis using the COMDQ questionnaire.

The tool used to measure quality of life in this study was the COMDQ questionnaire. This questionnaire examines the quality of life of patients with chronic mucosal diseases using 26 questions in four subgroups, including pain and functional limitations, treatment and medication, psychological and social status, and patient support. In the scoring system for recurrent aphthous stomatitis, the characteristics of lesions in the last three months and factors such as the number of lesions, the rate of recurrence of lesions, and the affected areas should be considered to determine the severity of the disease. Thus, the USS system, which is derived from the combination of the above items, was used. The USS system includes 6 subgroups, including the frequency of the aphthous lesions in the last three months, diameter, duration, ulcer-free period, location of aphthous lesions, and pain. Pearson's correlation coefficient was used to calculate the correlation between age severity and duration of the disease with quality of life. To compare the average scores of this questionnaire in two genders, an independent t-test was used, and the Mann-Whitney test was used if the data were not normal. Data analysis was done by SPSS ver 25 software.

In this study, 251 questionnaires were completed using the census sampling method. Among the study participants, 116 (46.22%) were men and 135 (53.78%) were women. The average total COMDQ score was 43.34±13.78 and no significant difference was observed between men and women in any of the dimensions of quality of life and the total quality of life score, as well as age (P>0.05). The correlation between COMDQ total score and general health (P=0.014) and also in comparison with oral health was significant (P=0.014). Also, the severity of lesions (USS score) (P<0.001), the number of aphthous ulcers in the last three months (P<0.001), duration (P<0.001), ulcer-free period (P<0.001) and a lower score in the subgroup of the location of oral ulcers (P=0.033), there was a significant relationship with the total score of the quality of life questionnaire.

Lesions of recurrent aphthous stomatitis are painful and have a long treatment period. In addition, various factors contribute to the occurrence of these lesions, and patients often suffer from them. Therefore, these lesions bother the patients and according to the results of the present study, they affect the quality of life of the patients. Raising awareness about the nature of these lesions and their follow-up should be on the agenda. Also, the mental and psychological aspects of the health of the patients should be taken into consideration in the treatment approaches.

For optimizing the operational efficiency of a wind farm in complex terrain, the wake study of wind turbines and the detailed analysis of the wind data are essential. In this research, Manjil wind farm located in Alborz Mountains with special topography and distinct wind regime had been studied. OpenFOAM has been applied for Computational fluid dynamics simulations of two wind speeds in different reference heights as case studies. Then, a comparison between the simulation results and available Supervisory control and data acquisition dataset has been done. The result pretended that velocity of the wake is recovered up to 85% after ten times the diameter of the turbine. In this distance, there is a 14.5% and 15.5% speed reduction on average for two simulations, with velocity on the hub height of 9 and 17 m/s respectively. The analysis of raw wind data shows that a high potential of wind energy is available in summer and there is almost no wind in wintertime, which causes some challenges for developing the wind farms under these conditions.

Population growth and industrialization have led to an increase in waste and sewage production, which is always a concern for urban managers. With the increasing population, in addition to increased waste production, the need for energy also increases. With the increase in energy consumption, a renewable source must be sought to meet the country's needs. Municipal solid waste and sewage sludge have a high potential for energy production due to the high volume of organic matter in them. Therefore, in addition to waste disposal, appropriate management of waste and sewage can be used as a suitable source of energy production. In this research, simultaneous management of sewage and solid waste in Tehran was carried out. For this purpose, information was implemented on a superstructural model, and then, using Python programming language and decision nodes, decision coefficients from 0 to 100 percent with a one percent step were considered. Finally, 592 scenarios were proposed, and two scenarios were selected as the best scenarios in terms of energy perspective, with the approaches of heat recovery and electricity production. In these two scenarios, approximately two million gigajoules and one million four hundred thousand gigajoules were recovered as the highest heat and electricity from simultaneous management of sewage and solid waste in Tehran city, respectively. By implementing this model for Tehran, urban managers can use waste and sewage as a source to meet the energy needs of waste disposal systems and supply part of the city's energy needs.

In recent years, the fight against the smuggling of goods and currency in our country has been a special category that has attracted the attention of statesmen, economists, producers and even the general public. The orders and menus of the Supreme Leader of the Revolution in this regard are another proof of the concern of the leader of the revolution for this sinister phenomenon.

The main purpose of this article is to investigate the impact of the national media on combating the smuggling of goods and currency

The research is applied in terms of purpose and is considered as quantitative research. The statistical population of this study is all experts in the field of goods and currency smuggling and national media, including experts from the central headquarters of the fight against goods and currency smuggling and national media experts, a sample of 385 of them from all over the country was randomly selected using the Cochran formula. . The data analysis method is based on structural equation modeling.

The findings from the analysis of the research data showed that the effectiveness of the national media in all three areas of social role (two dimensions), media function (four dimensions) and land factors (four dimensions) is effective in combating the smuggling of goods and currency. .

the contextual role of the media, which is related to providing the necessary background and platform for the role of the national media in combating goods smuggling, has the greatest impact, and after that, the social role of the national media is the second priority to influence the fight against goods smuggling, and finally the functional role The national media is the third priority for influence.

Recent years in the fields of accelerators of fundamental particles, satellites and radars are completely devoted to the design of the high power klystrons. Increasing the efficiency of such klystrons is an exclusive problem, which requires fundamental research in the processes of interaction of the electron beam with the field of resonators. The aim of this paper is to present new ideas for increasing the output efficiency of klystron tubes using clustered cavity with gap displacement. In this paper,clustered cavity resonators are used in the design of electron bunching to determine the effect on the bunching and output efficiency of the klystron tube. To improve the efficiency of a klystron tube designed with five single cavity, first by using a clustered cavity in the redesign of the structure, an increase in efficiency of 2.63% and 6.11% for three clustered cavity has been achieved. This increase in efficiency has been done without increasing the length of the wave-beam interaction area. CST and KLYC software have been used to prove this claim.

The study encompassed multiple forests within a 24,000-ha area in Ardal and Kiar counties, Chaharmahal and Bakhtiari province, Iran. It involved the analysis of tree and stand indices to assess the spatial characteristics of the forests along topographic gradients. The findings indicated that the forest stands exhibited irregular and heterogeneous patterns at the plot level, particularly in terms of diameter, height and uniformity indices. However, the density and tree species composition were consistent across all forest stands. The influence of slope on tree- and stand-based indices was generally not statistically significant, except for the height diversity index, which displayed higher values in forests situated on steep slopes. Changes in the geographic aspect and altitude did not exert significant effects on tree and forest indices, except for the tree diameter diversity index, which exhibited variations with altitude. The dominant tree species observed in all forests was Quercus brantii, followed by Pistacia atlantica. The presence of certain species was influenced by topographical factors, such as Daphne mucronata being exclusive to southern slopes and plains, Fraxinus angustifolia being limited to lower altitudes, and wild almond species being restricted to specific altitude ranges. Statistical analysis revealed no significant variation in plant species distribution across the topographical factors. Notably, families including Asteraceae, Poaceae, and Fabaceae exhibited the highest species counts within the entire study area.

Also, there is a significant direct relationship between internalized culture, symbolic culture, institutional culture, crystallized culture and the realization of resistance economy.

Pyrocatechol, a phenol derivative, is commonly found in industrial effluents at various concentrations due to its extensive use in multiple industries. These toxic compounds are resistant to biological degradation and pose significant threats to environmental and human health when they enter aquatic environments.

This study explores the removal of pyrocatechol from aqueous solutions using activated carbon coated with aluminum nanoparticles.

Laboratory materials included oak wood (collected from the mountains around Lorestan province, Iran), pyrocatechol, H 3 PO 4 , HCl, Al 2 O 3 , NaCl, NaOH, graphite oxide, and NH 3 . This experimental study was conducted on a laboratory scale. Oak wood was used to synthesize activated carbon, while aluminum oxide and oak moss were employed to produce aluminum nanoparticles using a green method. The characteristics of the adsorbents were examined using XRD, FESEM, FTIR, and BET analyses. Parameters such as contact time (5 - 40 min), pH (3 - 11), initial concentration of pyrocatechol (20 - 200 mg/L), adsorbent dose (50 - 250 mg), and ionic strength were investigated. The residual concentration of pyrocatechol was measured using a spectrophotometer at a wavelength of 275 nm.

The results indicated that maximum adsorption efficiency was achieved with a pyrocatechol concentration of 100 mg/L, a pH of 7, a contact time of 20 minutes, and an adsorbent dose of 250 mg. Isotherm and kinetic analyses showed that the adsorption data correlated well with the Langmuir model and the pseudo-second-order kinetic model, respectively.

Activated carbon derived from oak wood and coated with aluminum nanoparticles using a green method is highly efficient in removing pyrocatechol from aqueous solutions. This method is recommended as an effective, rapid, cost-effective, and environmentally friendly approach for the removal of pyrocatechol from aqueous environments.
