A New Approach to Eco-Logistics

Solution of problems in the field of ecology and environment has an important place at the state level, but also at the level of civil initiatives and individuals. It is in the result of increasing limitedness of natural resources and environmental consciousness. Eco-logistics is important effective tool which is the object of study, discussions of many experts in logistics, because it provides a wide scope of application. The main mission of eco-logistics is underling the importance of production processes, services and other activities connected with logistics impact on the environment. Suitable way of eco-logistics implementation creates conditions for logistics costs reduction and also for natural resources and environment saving. The paper presents new approach to eco-logistics and its new definition.

Reverse Material Flow of Worn-Out Conveyor Belts

Options for further use of worn-out conveyor belts were analysed and examined within the frame of research about options of reverse logistics. Reverse logistics has importance because one of the most important elements of reverse logistics is presented by wastes. By the research it is examined the reverse logistics network system for wastes. The article presents partial results of the aforesaid research in the field of reverse material flow of rubber wastes, especially results of theoretical knowledge of the current state of reverse material flow of rubber wastes in Slovak republic and re-processing of rubber wastes.

The Calculation of Force Effects of a Conveyor Belt of the Pipe Conveyor to Forming Rollers by FEM

The paper interprets the calculation of the size of force effects created by the reason of the effect of balled conveyor belt of pipe conveyor to the guide rollers located in the ring idler stations. Knowing them is essential for the research of dynamic resistances by pipe conveyors operations. Examined force effects were determined by the help of finite element methods. The calculation was performed by the program Abaqus. Presented calculation is realized by original calculation model. The results of the calculation present information about action of the effect force of the balled conveyor belt to the guide rolls in the ring idler station. Results became a basis for determination of postulates for identification of dynamic resistances. Their knowledge is the key element for conveyor belts lifetime increase.

Application of Reverse Logistics Processes in Belt Conveying

Reverse logistics is very interesting part of eco-logistics, application part of logistics. It creates conditions for various applications and also for various subjects. One form of application is connection of reverse logistics and processing of used wear conveyor belts. Conveyor belts present one of the most important parts of belt conveying and their lifetime is limited, for example by breakdowns, damages, etc. So, using of reverse logistics processes affords facilities for producers and users of conveyor belts at the direction of material saving and also saving of costs.

Financial Management of Non-Profit Organization Providing Specific Services

One of the most important role of all communities is to assure, create and take bearings to the effective support for non-profit sector, which is a very important element in providing of assistance in the cases when the help at the state level is not sufficient. On the present, non-profit organizations are experiencing their continuous development and in the result of this fact it is not uniquely determined the suitable „form“ of application of management and tools of managerial accounting in non-profit organizations, which creates the base of research, of which partial results are presented by this paper.
