According to unevenly epidemiologic studies on health outcomes in Iran, some adverse outcomes such as poisoning especially in children less noticed. We were interested to write some childhood poisoning factsheets to provide easy to understand information on pitfalls and challenges around epidemiologic measures, etiology and prevention in this context. Valid evidences about childhood poisoning i...

Hospitals are a symbol of social welfare and the last refuge of patients, which is the most important issue of the health system. Patient safety is the first and most important issue for the health system.  Before COVID-19, the World Health Organization (WHO) defined the Hospital Safety Index (HSI) to measure hospital preparedness for disasters. During the COVID-19 crisis, hospitals faced many ...

let $mathcal{r}$ be a  commutative ring with identity, let $a$ and $b$ be two $mathcal{r}$-algebras and $varphi:blongrightarrow a$ be an $mathcal{r}$-additive algebra homomorphism. we introduce a new algebra $atimes_varphi b$, and give some basic properties of this algebra. generalized $2$-cocycle derivations on $atimes_varphi b$ are studied. accordingly, $atimes_varphi b$ is considered from th...

the goal of this work is to present a case study demonstrator, presenting the field trial experience while extending network connectivity services in the campus, by enabling SDN-based equipment and coexisting with legacy hardware. The demonstrator aims to show the benefits of gradually adopting SDN technologies. This adoption will also improve and provide added value to traditional campus conne...

Network security management is becoming more and more complicated in recent years, considering the need of deploying more and more network security devices/middle-boxes at various locations inside the already complicated networks. A grand challenge in this situation is that current management is inflexible and the security resource utilization is not efficient. The flexible deployment and utili...

Business models of network service providers are undergoing an evolving transformation fueled by vertical customer demands and technological advances such as 5G, Software Defined Networking (SDN), and Network Function Virtualization (NFV). Emerging scenarios call for agile network services consuming network, storage, and compute resources across heterogeneous infrastructures and administrative ...

In this paper, we propose our on-going effort for developing NetOpen networking service that supports extended flowbased networking with programmable network substrates.
