“…Mashhad city with a relatively dry climate located in the northeast of Iran is the nation's second most populated city with over three million residents (Department of Studies and Planning, 2017). It has an area of about 351 km 2 and is 1050 m above sea level with an average slope of 0.6% (Akhlaghi et al, 2018;Pouresmaeili et al, 2018). The number of vehicle trips per day within the city has increased in recent decade from 4,035,560 to 6,576,268 with an increased rate of trips per person from 1.62 to two trips per 24 h (Department of Studies and Planning, 2007;Department of Studies and Planning, 2017).…”

This study explores which factors influence bicycle sharing systems acceptance as a new transportation technology by identifying and describing their relationships to intention and usage behaviour. Using the latest version of technology acceptance models (UTAUT2), this study examines the effect of Performance Expectancy, Effort Expectancy, Facilitating Conditions, Social Influence, Price Value and Perceived Safety on acceptance and usage of a newly introduced bicycle sharing system in Mashhad (MBSS), Iran. The mediating effect of intention to use MBSS on the relationship between these constructs and use behaviour was examined. A total of 600 questionnaires were distributed at 128 MBSS stations of which 271 users responded. The result of a regression analysis indicated that intention to use MBSS was predicted by all the studied constructs except for Price Value, while a path analysis showed that through the Behavioural Intention, Facilitating Conditions was the only significant construct to influence Use Behaviour. Findings did not support age, income, education, and experience as moderating the relationships between the constructs and Behavioural Intention. This study recommends tracking the barriers of acceptance of bicycle sharing system by those population groups who do not use the system or use it less than the others. Moreover, findings of this study suggest improvements to Facilitating Conditions such as integration of public transport and MBSS, relocation of the stations to improve their (equity of) accessibility and, introducing motivational promotion campaigns, improving cycling social status, and improved customer service of staff may make MBSS more interesting for citizens.

“…Studies on UV radiation in Iran are few and long-term spectral measurements of UV radiation are scarce in most parts of the country. Based on a survey in different cities in Iran (Bouzarjomehri and Tsapaki, 2012;Vatani et al 2013;Babaee et al, 2016;Akhlaghi et al, 2018), the natural radiation dose rate is above the normal range, which indicates the need to regularly review, monitor and report the annual effective dose of natural radiation (Shahbazi-Gahrouei et al, 2013). Most of the northern and northwestern provinces of Iran have a high risk of esophageal cancer.…”

Abstract. The UV radiation level at the Earth’s surface is generally affected by several factors such as time, geographic location, and climate. The first observations of solar UV radiation ever made in NW Iran, obtained in June 2019 are reported in this work. The analysis of hourly values of UV irradiances measured in the study area reveals significant diurnal variation during daylight hours, with lower values in the morning and afternoon and higher around noon. Mean hourly UV (A+B) ranged from 2755 to 10434 µW/cm2 with an average value being about 7960 µW/cm2. Mean hourly UV (C) ranged from 40 to 91 µW/cm2 with an average value being about 76 µW/cm2. The results of a short but intense measurement campaign in Ardabil-Sarein indicate the trends for geographical latitude, longitude, and altitude from surface UV measurements. The UV intensity is associated with geographical longitude (r2= 0.15 for UV (A+B); r2= 0.13 for UV (C)). Furthermore, UV intensity varies with the local latitude in the study area. There is a strong linear relationship between average UV and altitude and a trend of rising UV with increasing altitude is obtained. A decrease in UV radiation with increasing solar zenith (°) was observed. However, the correlation between UV radiation and solar azimuth (°) was not significant. Understanding the factors influencing near-surface UV radiation through systematic ground-based UV will help determine whether long-term changes occur as a result of changes in cloud cover or climate change, and how specific it means to identifying the causes.

“…Yousif et al [24] performed UVB radiation measurements at Valladolid University, Spain where the weather is warm in summer due wind velocity trend over Atlantic Ocean. The UV radiation rate in Mashhad, Iran is determined by Akhlaghi et al [25]. The results indicate that the average rate of UV in Mashhad is lower than 10 W/m 2 , which is the standard global.…”

This study examines the correlation between solar UVB and different weather parameters in Kuwait climate. To achieve that purpose, an experimental outdoor facility is designed and set up at the College of Technological Studies, Kuwait for regular monitoring of solar global radiation, UVB radiation and ambient temperature in Kuwait from beginning of January 1 st 2014 until the end of December 2019. Outcomes reveal that the change of solar UVB as well as global radiation through the whole day inaugurate the same behavior for the recorded data in clear day times. Statistical analysis is carried out to obtain a correlation linking UVB radiation and both ambient temperature and global solar radiation. Regression analysis of the current work shows that there is a solid correlation among UVB radiation and both ambient temperature and global solar radiation, especially for intermediate to small global solar radiation ranges. In addition, UV index is evaluated for various months at all day times. It is important to record that UV index with the maximum values is attained in May-August months through midday period. Also, UV index values do not surpass the accepted extreme value which is higher than 9 during any time of the study period.
