Pelagic Fishery

Interactions between seals and midwater trawl operations in the Australian Small Pelagic Fishery are common and can be lethal. The nature of interactions and effectiveness of a seal exclusion device (SED) in mitigating lethal interactions was assessed using underwater video. Recent fishing activity and the phase of the trawl operation significantly influenced interaction rates; interactions increased with the amount of recent trawl activity and were highest while the trawl was being set. Most seals accessed the trawl via the net entrance and exited via an escape opening located at the base of the SED. The size of the escape opening was the only operational factor that influenced mortality rates — simply enlarging the escape hole reduced lethal interactions by 79%. However, since all deceased seals dropped out of the net before they were brought on board, they would have gone unobserved without video monitoring. Limiting the concentration of fishing activity in space and time and refinement of the SED design, in particular to address dropouts, is recommended if mortality rates are to be reduced.

Operational Factor

The analysis of failure of unhardened and heat-strengthened R65 rails under operating conditions in the tangent sections of the track is presented taking into account the influence of the most important operational factor - the average static axial loads of the rolling stock. Non-reinforced R65 rails in the jointed track on the 12.5 m long wooden sub-rail base were considered based on the results of their single replacement in the entire range of their failures. The work of rails under operating conditions is estimated at average static axial loads of rolling stock as 7.5, 9.5, 16.5 and 19.5 tf (73.55, 93.16, 161.82 and 191.21 kN) at all stages of the tonnage at each load. The influence of the average static axial loads of the rolling stock on rail failure in specific operating conditions has been revealed. The features of the change in the intensity of rail failure are considered at all stages of their operation, both for the specified and for the average network level of the static load. The obtained statistical data on the effect of axial loads of rolling stock on the operation of rails can be used in the practice of track maintenance. In conditions of increasing axial loads up to 25, 27 tf, it is necessary to use rails of the appropriate quality; also it is expedient to create new rails for such operating conditions. It is necessary to perform an evaluation of the real operational qualities of the rails in order to use the rolling stock with the increased axial loads (25, 27 tf) in the transportation process in the most efficient way. In the long term, the results of such studies will be aimed at improving the operation of the systems for running track and railway car complexes.

The mechanical glass transition temperature ( T g ) of dried Cronobacter sakazakii cells varied depending on differences in drying methods and water activity (a w ) levels. Because the T g of the dried bacterial cells varied depending on the drying method and a w , the T g will play an important role as an operational factor in the optimization of dry food processing for controlling microbial contamination in the future.

Relations Of Power

The paper initially establishes the theoretical framework including the crucial notions of the contemporary philosophical and cultural studies the aim of which is to investigate the Global and Individual phenomena. Following the principal tenets of Paul de Man?s tropological approach, the paper also seeks to critically explore theoretical elaborations constituting their own discursive mappings, whereas, at the same time, the latter are subject to the acute critical theoretical endeavours in the context of constructing hyperdiscursive network and spatial logic of the Global, hence totalizing which is precisely to neutralize the Individual. Consequently, by means of their own metadiscursive ?schisms?, Foucault?s visibly-invisible interactive relations of power are established, within which the Individual equally constitutes itself as an operational factor of Jameson?s culture as megastructure on the next level of abstraction - cultural selfproduction. The final segment of the paper seeks to highlight the fact that, in the contemporary epoch, discourse coequally constitutes itself as a manipulative factor in Jameson?s ?New World System? and Baudrillard?s ?fatal strategies of seduction?. Henceforth, within the contemporary discursive mapping establishing itself as a paraliterature in its own right, there remains the issue as to what extent the metastasis of the Global conditions the metastasis of the Individual, and vice versa.
