The present study examined the effects of boundary strength and stress on nasal coarticulation with neighboring segments. Acoustic and nasal airflow data were recorded from four speakers as they produced intervocalic fricative-nasal and nasalfricative sequences that spanned a word-internal boundary or a word boundary under two different stress conditions. Although neither stress nor boundary af...

In this paper I study the e¤ects of environmental regulation which establishes upper and lower binding targets to pollution emissions. Essentially, I deal with the properties of a stochastic model of pollution control in continuous-time under emission targets and uncertainty, emphasizing dynamic nonlinearities. Inside the targets pollution behaves as if it were freely ‡oating until it hits one ...

In order to solve the problem of fuel pollution, the diesel fuel for power generation of marine was abandoned and shore power supply have been proposed at the historic moment. The Shore Power Supply which needs transferring 380V/50Hz to 450V/60Hz is used on shipping who need this kind of power, so effectively curbs the emissions of pollution gas into the air, and achieves the purpose of improvi...

Background: In order to protect the environment, humans are required to comply with environmental ethics, as set forth in environmental laws. Unfortunately, oil pollution has had many negative impacts on the Earth's environment in recent years, so various countries have been examining and deciding on new environmental laws over many years. Many decisions overlap with international law and have ...
