The management of wastes, in particular of industrial waste, in an economically and environmentally acceptable manner is one of the most critical issues facing modern industry, mainly due to the increased difficulties in properly locating disposal works and complying with even more stringent environmental quality requirements imposed by legislation. In addition, in recent years the need to achieve sustainable strategies has become of greater concern, also because some traditional disposal options, such as landfill, are progressively restricted, and in some cases banned, by legislation. Therefore, the development of innovative systems to maximize recovery of useful materials and/or energy in a sustainable way has become necessary. Industrial wastes are generated through different industrial processes or energy production utilities as additional materials. Industrial symbiosis theory defines non-deliberately produced material as by-products or valuable raw materials which can be exploited in other industrial avenues. Paper industry is a strategic industry in many countries but in the same time, the production of paper consumes high quantities of energy, chemicals and wood pulp. Consequently, the paper production industry produces high environmental emission levels mainly as CO2 due to energy consumption, or solid waste streams which include wastewater treatment sludges, lime mud, lime slaker grits, green liquor dregs, boiler and furnace ash, scrubber sludges and wood processing residuals. In terms of volume, most solids or liquids are those from the treatment of effluents, although waste from wood is also produced in large quantities.

Bosnian Abstract: U jugoslavenskom razdoblju dvije najistaknutije licnosti u politickom životu Bosnjaka iz Bosne i Hercegovine svoj život su zavrsile na istaknutim jugoslavenskim politickim pozicijama, ali je njihova smrt bila predmet raznih konstrukcija kako u nauci tako i u javnom diskursu. Rijec je o Mehmedu Spahi i Džemalu Bijedicu. U njihovom politickom djelovanju povezivala ih je jugoslavenska ideja, u koju su vjerovali, cinjenica da su obojica iznenada umrli, te naknadna mitologizacija njihove smrti. Ta mitologizacija je za cilj imala potpunu reviziju njihovog politickog djelovanja i uglavnom je bila produkt novog politickog konteksta. U ovom radu pokusavam kontekstualizirati njihovo politicko djelovanje i njihovu smrt, te objasniti razloge mitologizacije smrti svakog od njih.English Abstract: During the Yugoslav period two of the most prominent personalities in the political life of Bosniaks from Bosnia and Herzegovina ended their lives while occupying prominent political offices at the Yugoslav level. Their deaths however were subject to various constructions, in scholarly as well as public discourse. These two individuals were Mehmed Spaho and Džemal Bijedic. In their political work they were connected by the Yugoslav idea, in which they both believed, by the fact that both died suddenly, and the subsequent mythologization of their deaths. This mythologization had the aim to completely revise their political actions and was mainly a product of the new political context. In this paper the author attempts to contextualize the political activities and deaths of these two figures, and to explain the reasons for the mythologization that took place afterwards.

Next Generation Network (NGN) faces the challenge of the rapidly increasing amount of signaling. The growing amount of signaling is a consequence of several reasons arising from the fact that signaling is the main source of network intelligence, analysis, and user behavior monitoring. With the increase in signaling load and complexity, the network management becomes a challenging issue that can impact overall Quality of Service (QoS). To confront this issue, there is a need for reliable and forehand signaling transmission in NGN. As there is much confusion about the interpretation of this concept, this paper aims to provide an overview of the evolution of signaling transmission. Migration towards NGN is analyzed from the signaling perspective. The NGN signaling protocols and related transmission requirements are identified. Through the discussion of standard approaches, the paper considers our previously published approach to signaling transmission along with the current issues and emerging opportunities.
