Possible Cisco-based Fire Protection Solutions in Education Institutions

Abstract

Solutions based on Cisco firewall protection provide numerous possibilities for more efficient protection of the abundant quantity of data that is necessary for the operation of an educational institution. Firstly, data phishing can be complicated by the constitution of a virtual network. The IDPS-based access system enables the management center to identify a potential threat in a timely manner. Furthermore, the Cisco-type firewall of a new generation is able to verify the encrypted data in a way that avoids decoding and listening the communication itself. The AAA framework is also an imperative, as in case of a network, control of access is of the utmost importance.

Design of a Horizontal Anaerobic Reactor

Abstract

Adequate security measures at schools are essential, not only in Vojvodina but in all secondary schools. This work outlines the opinion of secondary school teachers concerning the mechanical and electronic protection of secondary school institutions. The present research aims to shed light on the significance of school security, and problems caused by its lack, as well as to offer suggestions towards increased security and protection.

Roaming of Materials Scientists in Biology: Structural Colours of Butterfly Wings

Abstract

The photonic nanoarchitectures occurring in the wing scales of Lycaenid butterflies were investigated by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and UV-VIS spectroscopy. We found that the males of all the nine investigated species possess photonic nanoarchitectures built according to the same general “plan”, but each species exhibits species-specific features which results in species-specific colours reproduced generation by generation with a high degree of accuracy.
