Evaluation of the “Aviation Security” programme in Polish Air Force Academy

The article presents the opinion of students on undergraduate majoring in “Aviation Security” in Polish Air Force Academy. The aim of the study was to describe the training and propose changes in the educational process of students for the security. The article presents the aims and tasks of public education for the security of the State and analysis of the results that have been obtained on the basis of a questionnaire. The result of the research of the proposed changes might be to introduce students in the education process for the security of the state, to increase the efficiency of the process. presented she stayed proposal of changes in the requirements for the education of students for the security of the state and in the program and plan of full-time studies of the first degree in “Aviation Security” in Polish Air Force Academ

The LubMedNet services for data storage and télédistribution

This paper is reports several Radiological and Oncological Information Systems integrated by a very efficient medical network system. The system covers the entire image flowpath in the Diagnostic Radiology Department (i.e. image acquisition, processing, archiving, long term storage) and allows for transmitting medical images through Municipal Area Network. The system has been working reliably since November 1999. About 22000 CT examinations have been archived using our system. Over 300 special examinations for radiotherapy planning have been sent to the Lublin Oncology Centre

Li-S battery recycling

Lithium-ion batteries are not situable for electric vehicles with high millage, military power supplies and fixed power networks. Therefore, the Li-S batteries have been intensively investigated, due to the high capacity, low cost, widespread source, and nontoxicity. The development of Li-S batteries causes increasing need to find the methods for their recycling. Some of them are discussed in the paper. The recycling of Li-S cell relates to its anode, cathode, electrolyte, binder and separator. The Li-S battery should be fully charged before recycling. There are potential methods for recycling of lithium from anodes, especially by re-melting. It is also possible to recycle some materials from the cathodes, especially sulfur by re-melting and graphite by dry crushing, Eco-bat Technologies method or the method investigated by Xiang et al. There is no effective recycling methods for electrolytes, binders and separators. It is necessary to carry out further studies on them

The Toxicity of Secondary Lithium-Sulfur Batteries Components

Currently, apart from the widely known lithium-ion batteries, there are competitive solutions in the form of, for example, Li-S batteries. While the results of studies on the toxicity of Li-ion battery components are published, such studies on the components of Li-S cells are just beginning. The purpose of the current review was to identify materials used in the production of Li-S batteries and their toxicity, especially for humans. The review showed many kinds of materials with different levels of toxicity utilized for manufacturing of these cells. Some materials are of low toxicity, while some others are of the high one. A lot of materials have assigned different hazard statements. For some of the materials, no hazard statements were assigned, although such materials are toxic. No data related to the toxicity of some materials were found in the literature. This points out the need to further studies on their toxicity and legal actions to assign appropriate hazard statements
