 More than two-thirds of the world’s population is likely to reside in urban areas by 2050. Rapid urbanization contributes to many contemporary challenges that confront cities. Sustainable urban development (SUD) is a widespread area of investigation that can be considered from various attitudes, such as environment, economy, society, technology, culture, and so on. This paper aimed to perform a bibliometric analysis of “sustainable urban development” research during 2002-2021, considering source types, subject areas, document types, affiliations, journals, countries, authors, and keywords. Also, Social Network Anal­ysis was applied to recognize mapping trends, status, and hot spots in SUD research and to discover co-authorship relations and international collaborations among countries worldwide. The results of this study showed that the number of SUD-relat­ed publications has remarkably increased by more than sixteen times over the study period. Social sciences” (24.6%), “envi­ronmental science” (21.2%), and “engineering” (13.4%) were the three major subject areas. China, with 539 publications (20.3%), was the most productive country in terms of the num­ber of publications. The most independent rate of the publica­tions belonged to India (76.5%), while Hong Kong ranked 1st in cooperator publications (61.6%). The “Sustainability” pub­lished the most related articles, followed by “Journal of Cleaner Production” and “Sustainable Cities And Society.” Among the top ten productive institutes and organizations, five affiliations were from China. “Deep learning,” “circular economy,” “big data,” “air pollution,” “spatial analysis,” “urban resilience,” “urban heat island,” “system dynamics,” and “cultural heritage” were the most increasing keywords in recent years, based on the author keywords analysis.

Detergents are a part of human life and are consumed for different purposes, particularly hygiene. In recent years, the detergent industry has experienced significant changes as a result of environmental concerns, the availability, and cost of raw resources and energy, consumer preferences, demographic and sociological trends, as well as global economic and political factors. Several review papers have been published on detergents, but no bibliometric research has been conducted in this field. This study aims to assess the trend of detergent research and show the related hotspots by conducting a bibliometric analysis based on 37650 published articles from Scopus from 2000 to 2022. Numerous significant aspects of these articles, such as subject categories, journals, authors, countries, and keywords, were examined systematically. According to the findings, the number of detergent-related papers has increased significantly over the past two decades. The United States was the leading country in terms of both quality and quantity, followed by China and Brazil. In addition, Detmann, E. from Sweden was the most productive author. Keyword analysis suggests that current research has focused on the development of effective cleaning products that are safe for humans and the environment.

Aims: The need for new antibacterial drugs is justified because many pathogens are currently resistant to available antibacterial drugs, and this is an alarming threat to the health of future generations. 1, 3, 4‑Oxadiazole has been shown to pose a wide range of antibacterial activity. Some of the marketed drugs also possess this heterocyclic moiety.  
Materials & Methods: The new derivatives of 1, 3, 4-oxadiazole were synthesized using a single-stage, high-yield method. Then, to measure the antibacterial activity of prepared derivatives agar well diffusion method was employed, and the minimum inhibitory concentration (MIC) and the minimum bactericidal concentration (MBC) were determined at a concentration of 1mg/mL with three replications.
Findings: Compounds 4a, 4d, and 4i exhibited a promising antibacterial activity against Acinetobacter baumannii PTCC1855. Among the three compounds mentioned, compound 4i showed the best performance with IZ=22±0.75 m.m , MIC=500µg/mL and MBC=125µg/mL at a concentration of 1mg/mL.
Conclusion: The new 1, 3, 4‑Oxadiazole derivative (4i) was shown to be a promising compound for pharmaceutical applications, by adding other functional groups to its structure, it is possible to increase the destructive power of the compound.

ta http-equiv=Content-Type content="text/html; charset=utf-8">ta name=ProgId content=Word.Document>ta name=Generator content="Microsoft Word 15">Aims: Antibiotic resistance is recognized as one of the most challenging public health problems in the world. The need for new antibacterial and antifungal drugs is justified because many pathogens are currently resistant to available drugs. Several components of 1, 3, 4‑oxadiazoles have been shown to pose a wide range of antibacterial activities.
Materials & Methods: The new derivatives of 1, 3, 4-oxadiazole were synthesized using a single-stage method. The structure of derivatives was evaluated by IR, H-NMR, C-NMR, and GC-Mass methods. Then to measure the antibacterial and antifungal activities of the prepared derivatives at a concentration of 0.5 mg/mL, agar well diffusion method was employed, and the minimum inhibitory concentration (MIC) and the minimum bactericidal/fungicidal concentration (MBC/MFC) were determined with three replications.
Findings: The study of antibacterial properties of the prepared derivatives showed the highest activity of the compounds 4b-g against Enterococcus faecalis strains, among which the compound 4g with IZ= 55.66 ± 0.5 mm and MIC=31.25 mg/mL had the greatest effect compared to the others. Also, the compound 4f with MIC= 125 mg/mL had a powerful effect against E. faecalis strains. In the case of fungal samples, the highest activity of the compound 4b was with IZ=12.33±0.5 mm against Candida glabrata and with IZ=13.33±0.5 mm against C. krusei strains.
Conclusion: The new 1, 3, 4‑oxadiazole derivatives (4b, 4d, and 4g) with tolyl, dimetylphenyl, and methoxyphenyl groups were shown to be a promising compounds for pharmaceutical applications so that by adding other functional groups to their structure, it is possible to increase the destructive power of these compounds.

Marriage is a demographic, social and economic phenomenon and age of marriage is a good instrument for its analysis. Age pattern of marriage among women in Iran has recently changed. Mean age at first marriage increased from 19.9 years in 1986 to 22.4 years in 1996 and to 23.3 years in 2006. In this article various factors affecting age of marriage are identified. An economic approach to define and identify parameters and variables of the model and the mechanisms that affect marriage and its timing are also used. Under this approach an econometric model to identify socioeconomic factors affecting women’s marriage pattern in Iran is developed. Data is from the 2001 Socioeconomic Survey of Iranian Households and the 1996 census of Iran. Proportional Hazard Cox Regression model is used to analyze data. The application of Proportional Hazard Cox Regression technique indicates that education has a statistically significant and strong positive effect on woman’s age at the first marriage. Other significant factors include rural–urban residence, ethnic group, age group, and socioeconomic status of the household.
