The focus of festival applications based on situation-aware ubiquitous computing has increased lately. An example of situation-aware applications is a smart festival management system. Since ubiquitous applications need situation-aware middleware services and computing environment keeps changing as the applications change, it is challenging to detect errors and recover them in order to provide ...

Large reduction in emissions of anthropogenic pollutants in a mega city during the week-long holiday gives an opportunity to investigate how the urban air quality reacts to reductions in emission. This study conducted a systematical examination of the “Spring Festival effect” over three consecutive winters in Shenzhen with a population of greater than ten million, and the difference in the conc...

However, many scholars could not agree whether this improvement was due to direct, indirect, or both forms WCF. Thus, study first investigated the role WCF students’ writing achievement; it then if there a statistically significant difference in achievemen...

Research on waste tire pyrolysis carbon black (PCB) in bitumen mixtures indicates that it has excellent high-temperature rutting resistance; however, the degradation of low-temperature crack resistance and water stability PCB-modified asphalt limits its wide application. Therefore, hot-mix (HMA) were enhanced by addition chicken feather (WCF). Based response surface methodology (RSM), a varianc...

To  communicate  effectively,  learners  have  to  become  proficient  in  both  the  language  and  the culture of the target language.  Being aware of socio-cultural frameworks does not mean that as an outcome of instruction learners have to become "native-like," but an awareness of L2 cultural norms can allow learners to make their own informed choices of how to become competent and astute l...

BACKGROUND A body mass index (BMI) ≥30 kg/m(2) and a waist circumference (WC) ≥80 cm in women (WCF) or ≥90 cm in men (WCM) are reference cardiometabolic risk markers (CMM) for Mexicans adults. However, their reliability to predict other CMM (index tests) in young Mexicans has not been studied in depth. METHODS A cross-sectional descriptive study evaluating several anthropometric, physiologica...
