Microwave-Induced Chemotoxicity of Polydopamine-Coated Magnetic Nanocubes

Polydopamine-coated FeCo nanocubes (PDFCs) were successfully synthesized and tested under microwave irradiation of 2.45 GHz frequency and 0.86 W/cm2 power. These particles were found to be non-toxic in the absence of irradiation, but gained significant toxicity upon irradiation. Interestingly, no increase in relative heating rate was observed when the PDFCs were irradiated in solution, eliminating nanoparticle (NP)-induced thermal ablation as the source of toxicity. Based on these studies, we propose that microwave-induced redox processes generate the observed toxicity

The essence and features of the shipbuilding cluster systems have been considered. The mechanisms of the organization of shipbuilding clusters are analyzed as well as the indicators of the effectiveness of their operation. The research aim is to develop the principles for the organization of the shipbuilding cluster system and use the models as a logistics tool in order to develop and operate the shipbuilding cluster system. A scheme of the functional decomposition of the shipbuilding cluster of operating system is developed. The competitive factors of the developed shipbuilding cluster system are: total cost of the design and construction of the vessel; turnaround time for construction of the vessel; quality of the product; required level of the technical maturity of the cluster members. The balance model should be used for planning the budget revenues. The properly constructed balanced scorecard, supported by the special software, allows each participant cluster focusing their resources (financial, human, technological, informational ones) on the implementation of the strategy and ensuring the steady traffic of your goals

The basic mechanism elements of the proactive management of ship repair enterprises are described. The research aim is to develop the basic mechanism elements of the proactive management of ship repair enterprises. The range of monitoring indicators of the production processes taking into account the features of the ship repair manufacturing is proved. The principles of implementation of controlling processes based on the budgeting system and earned value method are proposed. There are four approaches for implementation of the controlling system: a simple variance analysis of actual results from the planned ones; a budgeting control of the department with the elements of the factor variance analysis; a strategic approach to the variance analysis; a variance analysis taking into account the uncertainty. The recommendations on the information system structure which provides the implementation of the proactive management mechanism are proposed. Along with the introduction of the proactive management elements it is advisable to save the traditional schemes of management decisions, i.e. it is necessary to maintain a balance between the proactivity and reactivity in terms of resources cost

The solution of the problem of the development of a logistic unit (vessel) for the maritime cluster of the south of Ukraine as a standard logistic unit of maritime logistics has been considered. The use of a water transport logistic unit (taking a ship of mixed navigation as an example) for providing the practical application of the theoretical logistics foundations in the cargo shipping management is studied. One of the issues for the development of shipping and shipbuilding in Ukraine is the construction of a standard barge hull for large-scale manufacture. The comparative characteristics of ships with standard hulls are given. One of the promising directions of the shipbuilding development in Ukraine is noted. It is the construction of standard hulls for carriers, self-propelled and non-self-propelled barges, bunkering, fishing and maintenance vessels. The recommendations for the selection of elements for the construction of standard vessels for Ukrainian cargo fleet are stated. The foreign experience of large-scale shipbuilding is analyzed.
