background: considering high importance of heavy metals residue from view point of food safety, this study was conducted to determine the contents of chromium (cr), lead (pb) and cadmium (cd) in different tissues (liver, heart and muscle) of marketed chickens in mashhad, iran. methods: chicken tissues were collected from four popular brands distributed in different markets in mashhad, followed ...

This paper argues that discussion of new food-safety governance should be framed by the realization that the dominant food system within which food-safety governance is designed to makes food safe is itself a structural and systemic sources of food un-safety, poor health and a future of food insecurity for many. For some, an appropriate policy response lies in addressing the connections between...

In this paper, based on the imbalance of the supply-demand relationship of food, we design a spreading model of food safety risk, which is about from food producers to consumers in the food supply chain. We use theoretical analysis and numerical simulation to describe the supply-demand relationship and government supervision behaviors' influence on the risk spread of food safety and the behavio...

On January 30, 2020, the World Health Organization (WHO) announced coronavirus disease-2019 (COVID-19) as an international public health concern. Currently, due to COVID-19 world is facing a remarkable danger. As proposed by WHO, many countries have applied physical distancing together with obligatory use of mask practice stop transferral disease. Within these measures, people working in branch...

The demand for locally produced food is increasing as global food supply system has considerably affected the confidence of consumers by increasing tonne-kilometres, food safety risk, environmental impact, and disconnecting local food producers and consumers. However, local food suppliers are not in the position to compete with large scale food supply systems due to high logistics costs. The ov...

In this working paper, the National Institute of Civil Aeronautics of the Bolivarian Republic of Venezuela (Instituto Nacional de Aeronáutica Civil – INAC) presents a project to implement safety management system (SMS)/State safety programme (SSP) using an integrated administrative and management system for civil aeronautical safety (AEROSIG), with the intention of providing a useful reference ...

Reactive systems maintain an ongoing interaction with their environment, and respond to inputs from the environment by possibly sending outputs to it. Most importantly, in most reactive systems, the functionality performed in response to inputs is no longer limited to data manipulation and numeric computation. Instead, a sizable portion of effort is often required to focus on control logic that...

In this paper we use equation solving for translating internal tests derived for a component embedded within a composite system into external tests defined over the external alphabets of the system. The composite system is represented as two communicating finite state machines (FSMs), an embedded component FSM, and a context FSM that models the remaining part of the system and which is assumed ...
