BACKGROUND Engineered nanomaterials (ENMs) are marketed as a substance or mixtures and are additionally used due to their active agent properties in products such as pesticides or biocides, for which specific regulations apply. Currently, there are no specific testing strategies for environmental fate and effects of ENMs within the different regulations. An environmental test and risk assessmen...

In this paper we present the novel design, implementation, and evaluation of an ad-hoc parallel I/O system (AHPIOS). AHPIOS is the first scalable parallel I/O system completely implemented in the Message Passing Interface (MPI). The MPI implementation brings the advantages of portability, scalability and high performance. AHPIOS allows MPI applications to dynamically manage and scale distribute...

A sophisticated method for node deployment can efficiently reduce the energy consumption of a Wireless Sensor Network (WSN) and prolong the corresponding network lifetime. Pioneers have proposed many node deployment based lifetime optimization methods for WSNs, however, the retransmission mechanism and the discrete power control strategy, which are widely used in practice and have large effect ...

OBJECTIVE Management of pulmonary atresia with intact ventricular septum (PAIVS) can be directed to either biventricular repair or univentricular palliation. The optimal management strategy has yet to be defined. METHODS All patients operated at the Royal Children's Hospital, Melbourne for PAIVS between 1990 and 2006 (n = 81) were reviewed. Patients were retrospectively stratified into a simp...

The Association of Southeast Asian Nations (ASEAN) is a confederation of 10 sovereign states occupying approximately 1.7 million square miles of Southeast Asia with an estimated population of just under 630 million. Southeast Asia continues to have one of the world's highest rates of cervical cancer-related death. Organised training in cervical cancer screening is essential but lacking in low t...
