Excess gross motor activity (hyperactivity) is considered a core diagnostic feature of childhood ADHD that impedes learning. This view has been challenged, however, by recent models that conceptualize excess motor activity as a compensatory mechanism that facilitates neurocognitive functioning in children with ADHD. The current study investigated competing model predictions regarding activity l...

Introduction: Human activities, such as mining, result in the elevation of natural ionizing radiation in the environment. Jos-Plateau, Nigeria, including Kuru-Jos has experienced commercial tin mining in the past, and local mining is still being practiced in this area. Therefore, it is important to assess the radiation exposure due to grown crops and the farm soils in ...

The approach taken in the WHO Guidelines for controlling radiological hazards public water supplies has two stages. first is an initial screening gross alpha and beta activity to determine whether concentrations are below levels at which no further action required; if these exceeded, investigation of concentration individual radionuclides comparison with specific guidance levels. Mineral obtain...

Abstract One of the important issues today is problem global warming and climate change. Global change are phenomena increasing concentrations greenhouse gases in atmosphere due to various human activities as a result economic development activities. The success can be seen from increase value national output form gross domestic income. Therefore, purpose this study determine effect measured by...

Mobile technologies have deployed a variety of Internet–based services via location based services. The adoption of these services by users has led to mammoth amounts of trajectory data. To use these services effectively, analysis of these kinds of data across different application domains is required in order to identify the activities that users might need to do in different places. Researche...

National governments can only tax the economic activity they either directly observe or that is reported by municipal authorities. mining, a very common phenomenon in Colombia, changed with a tax reform that reduced the share of revenue transferred back to mining municipalities. To overcome the challenge of measuring illegal activity, we construct a novel dataset using machine learning predicti...

industrial-scale r&d it projects depend on many sub-technologies which need to be understood and have their risks analysed before the project can begin for their success. when planning such an industrial-scale project, the list of technologies and the associations of these technologies with each other is often complex and form a network. discovery of this network of technologies is time con...
