Food safety begins on the farms and farmers play a crucial role in producing healthy food. Several factors were investigated here including water quality, labor health, health facilities, packaging and storage, transportation, fertilizers and solid organic materials, and field sanitation to reach more comprehensive results. So, 380 farmers were selected from 77 villages of rural areas of Gonbad...

In recent projects on operating-system verification, C and C++ data types are often formalized using a semantics that does not fully specify the precise byte encoding of objects. It is well-known that such an underspecified data-type semantics can be used to detect certain kinds of type errors. In general, however, underspecified data-type semantics are unsound: they assign well-defined meaning...

The occupational exposure limits (OELs) in Taiwan was promulgated in 1974 and has been revised five times since then. Many of the OELs were adopted from the most recent ACGIH TLVs and US OSHA PELs. A total of 483 chemicals were listed in the current Taiwan OELs Standard. The procedures of OELs development in Taiwan include the IOSH organized a recommended exposure limits (RELs) Committee to sel...

We propose a high-level language based on rst order logic for expressing synchronization in concurrent object-oriented programs. The language allows the programmer to declaratively state the system safety properties as temporal constraints on speci c program points of interest. Higher-level synchronization constraints on methods in a class may be de ned using these temporal constraints. The con...

SH&E PROFESSIONALS have a vested interest in knowing more about top-level management—most of whom determine what resources are designated for safety within organizations. By knowing more about these managers’ perceptions of safety, an SH&E professional may be better equipped to negotiate for valued resources. For example, suppose you know that top-level managers within your industry think that ...
