This study investigated the medicinal properties of lavender and ways to increase its production.

To collect relevant data, we reviewed Out of twenty to thirty studies reviewed on the metabolites of this valuable plant and presented the results in the form of a review. Ultimately, we proposed a solution to increase the production of secondary metabolites.

The studies conducted on the therapeutic effects of this plant and the promising results led us to present a plan based on a strategy to increase the production of secondary metabolites. Lavender has been studied in a wide range of diseases and lavender aromatherapy has been shown to reduce anxiety before surgery. It has been found that lavender can be useful in preventing heart damage in people at risk of myocardial infarction and ischemic heart disease.

Various elicitors should be used in tissue culture conditions to produce secondary metabolites effectively.

Consumption of tea and herbal teas is increasing worldwide due to their beneficial substances and daily antioxidant properties. However, in unfavorable environmental conditions, biological contamination can occur and cause a variety of diseases in humans and animals. In the meantime, fungal infection is of special importance as it produces secondary metabolites (mycotoxins). Mycotoxins affect various tissues of the body and their acute and chronic toxic effects can have serious problems for public health. Health risk varies in terms of mycotoxins and depends primarily on the geographical area and economic status of the population. This review examines the published articles about determining the presence of mycotoxins in herbal teas and teas and transfer to infusions 1997-2019 using high technique apparatus. The collected information was obtained from PubMed, Science Direct, Scopus, and Web of Science. This review decided to investigate the mycotoxins levels in tea and herbal tea and then consider different and effective proposed methods of removing or reducing mycotoxins.

This study developed a dispersive liquid-liquid microextraction technique followed by spectrophotometric analysis for preconcentrating/determining penicillin G benzathine and penicillin G potassium.

The procedure was based on forming a color complex of penicillin G with bromothymol blue and its extraction by DLLME. The univariate method was employed for optimizing the parameters.

Optimized conditions for extracting benzathine and potassium penicillin G were 1.5 mL methanol and acetone as dispersive solvents; 300 μL CHCl3 and 250 μL CCl4 as extracting solvents; pH 4 and 3; 0.8 mL and 0.9 mL bromothymol blue (10-3 M), and NaCl 0.8 M for both analytes. The calibration curves were linear over the ranges 50-750 and 800-950 IU mL-1 for analyzing benzathine, and 800-1600 and 1750-6500 IU mL-1 for potassium penicillin G. The relative standard deviations and detection limits were obtained to be 6.53% and 0.101 IU mL-1 and 4.65% and 0.149 IU mL-1 for determining benzathine and potassium penicillin G, respectively.

The proposed method was employed for extracting and determining penicillin in human plasma, urine, orange juice, and milk, with acceptable recovery values of 94.3-102%.

 This study investigated the effect of waste separation from the source on the chemical characteristics of wet waste in Ardabil city.

A sample of wet waste material was collected from each district of the 3rd and 4th regions of Ardabil city in order to analyze of Cd, Pb, pH, EC, TDS, OC, K, Ntotale, and P values with standard methods.

The results showed that the average concentration of Pb was determined to be 102 mg/kg in area 3 and 125 mg/kg in area 4. Also, the average concentration of Cd in municipal waste compost samples was 3.139 mg/kg and 4.21 mg/kg in regions 3 and 4. The percentage of nitrogen (N) in both managed samples of regions 3 and 4 was 0.32% and 0.18%. The average percentage of phosphorus (P) in unseparated and separated urban waste compost of region 3 was 0.089% and 0.13%, respectively. In region 4, the average percentage of P in managed municipal waste compost was 0.24% and in unmanaged was 0.201%. The concentration of potassium (K) in separated urban waste compost in areas 3 and 4 was found to be 60.2 ppm and 39 ppm, respectively.

According to the results, it can be said that the effect of management on the number of heavy metals in the waste was significant at the possible level of P > 5%. Further, waste separation at the source systematically reduces the waste with heavy metals.

An important factor in preventing industrial accidents includes the ability of employees to have awareness of the work situation, understand the information from it, and predict how situations will develop. In this study, we examined the role of fatigue and work-related stress in predicting work situation awareness among workers.

The current study was a cross-sectional study. The sample consisted of 180 employees in the National Petrochemical Company in 2022 year that was selected according to the stratified random sampling method and responded to questionnaires about demographic characteristics, work situation awareness, work stress, and fatigue. The data were analyzed by correlation techniques and stepwise regression.

The results showed that there was a significant internal correlation between research variables. Also, the results of stepwise regression analysis revealed that fatigue and work stress significantly predicted, respectively, almost 11% and 16% of variances in work situation awareness among workers.

According to the findings of the present study, fatigue and work-related stress can predict work situation awareness. Therefore, considering these variables can be significant in promoting work situation awareness among workers.

The present research was conducted to achieve sustainable development and optimal use of environmental resources for identifying and prioritizing fire risk factors and fire management in Vesiye forest park located on the southern slopes of Alborz, Iran, to control and reduce the resultant destruction.

The three-round Delphi questionnaire and previous information were used to identify the most important fire risk factors in the studied forest park, which were subsequently ranked and weighted using Analytic Hierarchy Process (AHP).

The effective factors in the fire were identified to be vegetation type, slope, slope direction, distance to roads, distance to settlements, presence of tourists, altitude changes in the region, annual temperature changes, vegetation density, land use, atmospheric humidity percentage, wind speed, direction and the presence of hunters, and animal husbandry, respectively. According to the analyzed data, the highest ranks were assigned to vegetation type (0.2785), slope (0.1875), slope direction (0.1495), distance to roads (0.1075), and distance to settlements (0.0665), and the lowest weight to height (0.055).

The results revealed that the vegetation type has provided suitable conditions for fire in Vesiye Forest Park due to its high flammability factor as a fuel for the fire and the distance to roads as the factor of easy access for tourists to the forest park.

This study was conducted to determine the factors affecting the professionalism of human resources management in the Ministry of Industry, Mines, and Trade.

A survey method was selected to collect data. We asked the managers of the Ministry of Industry, Mines, and Trade to answer the questionnaire. The statistical population included 165 vice presidents and heads of the Ministry of Mining Industry and Trade, who were selected by simple random sampling. The measurement tool was a Delphi questionnaire and researcher-made questionnaires. Reliability, convergent validity, and divergent validity of the data were tested. The relationship between the investigated variables was tested based on a causal structure with the partial least squares technique, and then the Goodness of fit (GOF) index was calculated.

The coefficient of determination of the endogenous structures of the research model was desirable. Moreover, the coefficient of determination of merit-oriented and health-oriented ministry creation was reported as 0.527 and 0.707, which were acceptable values. Also, cross-validity redundancy and commonality were obtained in the range of 0.15 to 0.35≥.

The predictive power of the research constructs is estimated as a medium to strong.

Despite the considerable health benefits of walking on human health, pedestrian traffic accidents seriously threaten people’s safety. Specifically, the risky behaviors of pedestrians may lead to dangerous situations while crossing the road. Few studies have examined the relationship between high-risk pedestrian behaviors and some of their characteristics. The present study aimed to investigate the risky behaviors of pedestrians and their relationship to some demographic variables while crossing the street.

This descriptive-analytical study was conducted among 700 pedestrians over 18 years old. Data were collected using the Pedestrian Violations Questionnaire (PVQ). Convenience sampling was done in areas with different socioeconomic levels. The data were analyzed by the SPSS version 16 using an independent t-test, one-way ANOVA, chi-square, and Fisher exact tests at a significance level of 0.05.

The results indicated a significant relationship between risky pedestrian behaviors and demographic variables, including age, marital status, and education. However, there was no statistically significant difference between the risky behaviors of females and males and their involvement in accidents.

Pedestrian risky behaviors seem to be strongly correlated with age. Education can also be a predictor of risky behaviors.
