One of the largest sources of methane emissions is landfills, and various models have been developed to predict landfill methane production and emissions. The main goal of this research is to utilize the inverse Gaussian model to estimate g methane greenhouse gas emissions and model it using field data. This study introduces a simple method to estimate the amount of methane emissions based on ambient methane concentrations.

In this research, the methane emission rates from landfill were estimated for warm (July) and cold (February) seasons using a sampling campaign from 27 stations and standard inverse Gaussian dispersion equations. Monte Carlo simulation was also employed. To determine the model, an optimization-based method, along with inverse scattering modeling, was utilized to process surface emission monitoring data.

The model results indicated during the cold (February) and warm (July) seasons, the methane emission rates were estimated at 1696.99 and 16.53 g/s, respectively. These findings confirm that the methane production and emission during the cold season were lower than in the warm season, likely due to reduced temperature and bacterial activity.

The method used in this study, the inverse Gaussian dispersion model, can be applied to estimate methane gas emission rates from other landfills. However, it necessitates the permanent recording of data and the use of daily or weekly averages in calculations to mitigate potential errors and enhance the accuracy of modeling.

Rodents are the reservoir of many zoonotic diseases, including some helminth infection. The necessity to identify rodents and parasites which are transmitted through in different geographical areas of Iran and control and prevention measures can be very important from a health point of view.

In this study 40 rodents were caught from different parts of Alborz province from autumn 2018 to autumn 2020. Internal organs and viscera of mice erer examined after dissection using direct parasitological methods and parasites isolated from each rodent were identified in terms of genus and species.

Of the 40 rodents killed, 57.5% were infected with parasitic helminth. Detected worm species include Hymenolepis diminuta (17.5%), Hymenolepis nana feraterna(7.5%), Syphacia obvelata(7.5%), Syphacia muris(2.5%), Aspicularis tetraptera(7.5%), Trichuris muris(15%), Cysticercus fasciolaris(Taenia taeniae formis Larva Stag)(2.5%), Trichosomoides crassicauda(2.5%).

The results indicate the infection of rodent in Alborz province with different types of worms. Isolation of some zoonotic worm parasites from rodents in urban and rural communities reminds the neceeity of more attention for control and prevention measures as the most important action to prevent spread of parasitic disese in province.

Achillea millefolium L. is one of the most famous medicinal herbs that has been used extensively in ancient medicine for the treatment of diseases in general and wounds and burns in particular. This plant has many subspecies that different compounds of monoterpene and sesquiterpene are found in its essential oil. The purpose of this study was to analyze and compare the yields and essential oil compositions of two subspecies of Achillea millefolium subsp. millefolium and Achillea millefolium subsp. elbursensis with an economical usability approach in the pharmaceutical and medical sciences. For this purpose, two subspecies were collected from two subspecies in flower and leaf mountain range in July and flowering with three replications. Essential oil extraction was performed by Clevenger method and essential oils were identified by mass spectrometry chromatography (GC / MS). The results of analysis of variance showed that there was a significant difference between the two subspecies in flower and leaf essential oil yield at 1% level and the highest yield belonged to Alborz flower. Also, comparison of the essential oils and essential oils of Alborz aquatic leaves showed that the major part of the essential oils of both organs was chamazolene and was always higher in flower (79.3%) than in leaves (69.2%). However, in the Hibernians, the composition of 1 and 8 cineol was 14.4% in flowers and 5.6% in leaves. Thus, Alborz subspecies can be a unique natural economic resource for the pharmaceutical industry in the production of comazolene-containing drugs such as anti-inflammatory drugs and skin diseases and a subspecies of thousands of leaves grown in Alborz Mountains for extraction of 1 and 8 cineols in various medical and pharmaceutical applications.

Effective communication is an important factor in pre-hospital care. The emergency medical communication and dispatch center is one of the most stressful work environments in the healthcare domain so that it is essential to assess the harmful factors associated with this work environment. According to the guidelines of pre-hospital emergency procedures, it should take 120 seconds from the triage nurse response to the moment the mission is announced. The present study aimed to investigate the effect of ergonomic status at the workplace on the time of the announcement of the mission to dispatch personnel working at emergency medical communication and dispatch center. This study was conducted based on a descriptive-interventional design. In total, 36 participants were randomly selected from emergency medical communication and dispatch center. The data were collected using luxmeter, sound meter, and rapid office strain assessment. This study evaluated the time of the mission announcement by the communication and dispatch staff. The data were analyzed through descriptive statistics. P-value less than 0.05 was considered statistically significant. According to the results, the intervention affected the time of call registration and the mission assignment. The measured time before the intervention was 2.02s which decreased to 1.92s after the intervention. Therefore, the results indicated that the intervention significantly contributed to the differences between the times of registration until the mission assignment. It can be concluded that the improvement of ergonomic status can have effects on the staffs' performance.

Alborz Province is one of the provinces that accepted immigrants. Immigration has a profound effect on physical and mental health in elderly. This study was performed to assess the health status of Alborz province older population.
In this cross-sectional study, 235 subjects were enrolled (113 men and 122 women) aged ≥ 60 years using multi-level proportionated cluster random sampling that selected from 19 cities of this province. Data was collected by a demographic questionnaire, measuring anthropometric characteristics, and blood pressure and using "Mini Nutritional Assessment", ”Geriatric Depression Scale-15 ", “Katz’s Activity of daily living”, and "Lawton’s Instrumental activities of daily living”. Data was analyzed with spss21.
The mean age of the participants was 68 (6. 00) years. The prevalence of anxiety and depression among the participants was as٪ 51. 5 and 34٪, respectively. At risk or malnutrition was observed in 27٪ of the participants and ٪ 54. 5 had suffered dental problems and ٪ 49. 8 also had problem in walking.
Overall, the health status of elderly people in the Alborz, perhaps slightly better than the national average, but the high prevalence of metabolic disorders also the high prevalence of depression and anxiety require serious intervention by policy makers to promote the health in elderly.

Introduction and The nature and type of chemicals used in industrial processes, treatment and management of wastes resulting from them complicated. This study aimed to investigate wastewater management, manufacturing industries Savojbolagh city Alborz Province was from an environmental standpoint in 2013-2014
This study is type of cross-sectional. The three field visit, a questionnaire survey data and control / monitoring in industrial plants with more than 50 workers (totaling 108 units) were used. To do this research from the Environmental Protection Agency's questionnaire was used. The questionnaire included questions about the quantity, quality and wastewater management, industrial manufacturing setting. How to manage of industries Wastewater treatment plants, based on four indicators of wastewater production, production per capita, per capita of BOD, per capita of COD, from 1 to 6 are ranked. Rated for better environmental management in each index is defined.
The produced wastewater industries studied, 1942 cubic meters per day respectively. Food industry alone produces 59 percent of total industrial wastewater. The highest per capita BOD related to the industry (slaughterhouse) by g / d 320 per worker and the cellulose industry with the highest per capita COD g / d561 per person. 76% of Studied industries do not have any strategy to reduce the production of waste. 34% of industries have treatment plants that only 17% of the industry to comply with effluent discharge standards. The most common method of disposal of Treated wastewater and untreated are well absorbed.
Based on this assessment, management of industrial wastewater for agriculture (slaughterhouse) unfavorable and non-metallic mineral industries were favorable.
