background and purpose: it is extremely important to recognize the qualitative and quantitative characteristics of this type of waste before any planning on them due to the lack of the prepared program in the field of household hazardous waste (hhw) management in the country. this research has been done in babol, iran, in order to achieve this important goal. materials and methods: the cross-se...

Palaeontology formed the basis for defining most of the geological eras, periods, epochs and ages that are commonly recognized. By the same token, the Anthropocene can be defined by diverse palaeontological criteria, in accordance with commonly accepted biostratigraphic practice. The most useful Anthropocene biostratigraphic zones will be assemblage and abundance zones based on mixes of native ...

Users of mobile networks can change their identifier in regions called mix zones in order to defeat the tracking of their location by third parties. Mix zones must be carefully deployed in the network to reduce the cost induced on mobile users and to provide high location privacy. Unlike most previous work that considers a global adversary, we consider a local adversary equipped with multiple e...

Transportation of hazardous goods is a demanding and risky job. The greatest risks, dangers consequences for the population environment are associated with transport goods. Today, numerous systems software packages have been developed, aim which to improve performance this type mitigate possible accidents. By monitoring adaptive management in road traffic, traffic accidents can be repaired more...

Work zones in the United States have approximately 700 traffic-related fatalities, 24,000 injury crashes, and 52,000 non-injury crashes every year. Due to future highway reconstruction needs, work zones are likely to increase in number, duration, and length. This study focuses on analyzing the effect of work zone duration mainly due to its policy-sensitivity. To do so, we created a unique datas...

The first and most important step in road safety management is the identification of roads with safety needs. The most prevalent road screening technique utilizes the quality control method. Exposure data is used to estimate the expected number of crashes, which is then compared to the actual number of crashes in order to identify locations with safety needs. This approach must be modified when...

Hard rock aquifers for the purpose of this Paper mean the non-carbonate, fractured rock aquifers in the terrain covered by crystalline basement complex, metamorphic rocks and also by extensive effusive volcanic rocks like the basalts of western India (Deccan traps. Ground water development in hard rock aquifer areas has always played a secondary role compared to that in the areas having high-yi...

Hazard perception (HP) tests are used in several developed countries as part of the driver licensing process, where they are believed to have improved road safety; however, relatively little HP research has been conducted in developing countries, which account for 80% of the world’s road fatalities. Previous research suggests that drivers in these countries may be desensitized to hazardous road...

Pavement maintenance is vital for travel safety and thus detecting dangerous road conditions in real-time fashion is desirable. Using off-the-shelf sensors and a wireless sensor network product to detect such conditions at a low cost poses many challenges. To meet these challenges, a “Smart Dust” (i.e., the Mica2 Motes)-based sensor network is adopted in a proof-of-concept study to monitor pave...
