CRITICAL INFRASTRUCTURE PROTECTION WITHIN THE EUROPEAN UNION [PDF]

Journal of Defense Resources Management, 2013
The new dynamics and intensity of the risks and threats posed to societal functioning and citizens’ security have acquired new meanings. Consequently, an integrated approach to the concept of ”critical infrastructure” is necessary. The critical nature of

Principles for management of risks of critical infrastructure [PDF]

, 2018
On the basis of present knowledge, the critical infrastructure is a set of physical (technical and material), cyber and organizational subsystems of human system that are necessary for ensuring the protection of: human lives, health and security ...

Skew critical problems

, 2007
Skew critical problems occur in continuous and discrete nonholonomic Lagrangian systems. They are analogues of constrained optimization problems, where the objective is differentiated in directions given by an apriori distribution, instead of tangent ...

Emergency and critical care services in Tanzania: a survey of ten hospitals. [PDF]

, 2013
While there is a need for good quality care for patients with serious reversible disease in all countries in the world, Emergency and Critical Care tends to be one of the weakest parts of health systems in low-income countries.

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

FEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

FEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

Role of Chlorides in Corrosion of Reinforcing Steel in Concrete

Corrosion and Materials Degradation
Chlorides have long been held responsible for the initiation and progression of the corrosion of reinforcing steels in concrete structures, with higher concentrations assumed to cause earlier and more severe subsequent reinforcement corrosion.

Vulnerability and Protection of Critical Infrastructures

, 2004
Critical infrastructure networks are a key ingredient of modern society. We discuss a general method to spot the critical components of a critical infrastructure network, i.e. the nodes and the links fundamental to the perfect functioning of the network.
