The development of novel foods produced through agricultural biotechnology is a complex three-stage process: gene discovery, line selection, and product advancement to commercialization. The safety of genetically modified foods is an integral part of the overall developmental process throughout all of the stages. In the discovery stage, the safety of the gene, its source, and the gene products ...

The virtual class 15] construct was rst introduced in the language Beta to provide added expressiveness when used with inheritance. Unfortunately, the virtual class construct in Beta is not statically type-safe. In this paper we show how a generalization of the semantics of object-oriented languages with a MyType construct leads to a variant of virtual classes which needs no run-time checks. Th...

The vascular bioactivity/safety of nanomaterials is typically evaluated by animal testing, which low throughput and does not account for biological differences between animals humans such as ageing, metabolism disease profiles.

introduction: since hospitals give their services to a huge number of people most of whom are sick and disabled and also because they have many expensive and modern equipment and facilities, any negligence regarding the standards of safety management leads to severe damages including financial ones. this may even result in irrecoverable consequences such as their clients’ death. so, this invest...
