The rare earth elements (REE) are vital to innovation technologies and society and are important for the industry, especially for high-tech solutions. In the modern world, anumerous applications have been developed using rare earth elements (REE), implying human exposures and raising unclear questions as to REE-associated health effects. Protecting the environment and public health from disadvantageous...
The paper discusses options for assessing risks with a view to identifying the nature and scope of the impacts of non-conformities and defining improvement opportunities. Such options are described in terms of hazards and opportunities. The opportunities reflect the measures required to increase the chances of establishing more effective safety management systems. The hazards reflect the circumstances...
A composite material is a macroscopic combination of two or more distinct materials, having a recognizable interface between them. Modern composite materials are usually optimized to achieve a particular balance of properties for a given range of applications. Composites are commonly classified at two distinct levels. The first level of classification is usually made with respect to the matrix constituent...
Green Supply chain, Green Packaging, Eco-labels, and Eco-design strategies are concepts that are discussed frequently within scientific and political debates. Eco-design strategies for Lifecycle Design include the Eco-design Strategy wheel which presents eight Eco-design strategies: New concept development, Selection of low-impact materials, Reduction of materials usage, Optimization of production...
Shade effect is a defect of the images very often invisible for human vision perception but may cause difficulties in proper image processing and object detection especially if the aim of the task is to proceed detection and quantitative analysis of the objects. There are several methods in image processing systems or presented in the literature, however some of them introduce unexpected changes in...
Currently operating enterprises are more and more willing to adopt a process approach in their structures. The process approach means the transition from traditionally understood management towards adapting to constantly changing environmental conditions. This change is accompanied by the possibility of using a wide range of tools of ICT technology, that allow modelling of any type of process occurring...
In this article presented results of researching corrosion of steel bars in aggressive environment in time under loading. For researching were used special equipment. The experience and research works shown that steel bars in the crack cross-section area can be corrode. With increasing width of crack in re-bars and power of aggressive of environment increased the level of corrosion and decreased time...
The underlying objective of the paper is to indicate pro-environmental awareness level in micro and small enterprises and its influence on this sector’s activity in the context of environmental management. The author has introduced a taxonomy of pro-environmental awareness and also pro-environmental security, pro-environmental culture and pro-environmental ethics. Heterogeneous pro-environmental attitudes...
The strategic importance of information for the functioning of each economic entity forces entrepreneurs to properly protect them against loss, unauthorized disclosure or unauthorized modification. Hence, organizations build complex security systems taking into account state-of-the-art technical solutions, while belittling often the most important element, which is the human factor. It should be emphasized...

The study presents general assumptions of policies related to fire protection and evacuation of public buildings. Have been defined groups of human factors that have a significant impact on the efficiency of preventive actions taken and in the event of a threat. Next, the research methodology and results of questionnaire surveys carried out in randomly selected student groups are presented. A number...
During our research, we focus on a less researched area in the development of autonomous vehicles. Automotive industry is turning more and more from conventional, internal combustion engine equipped vehicles to the electric cars. Today, electric driving is mostly limited to urban traffic, this is the area where range and refueling limits can be a real alternative. However, it is important to think...
This paper presents the analysis of existing forms of heat absorbing surfaces of air solar collectors, which gained the greatest popularity in the world. The obtained data allowed to conclude that there is a need for the development of solar collectors with air as a coolant with an improved form of heat absorber, which will reduce the operational and capital costs of solar systems and allow the efficient...

The author also presents the principles of training, including H&S training, considering: demonstrativeness, accessibility, awareness of social responsibility, regularity, knowledge durability and binary relations between theory...
Theoretical and experimental studies of new technology and equipment on the fulfilled cables and ropes of handling equipment are provided for diagnosis of main process. The result of the safe processing is steel fiber which is used further for production of a steel-fiber reinforced concrete. The research offered a number of essentially new diagnose methods which considerably increases engineering...
Spontaneuos combustion (or self-ignition) is the initiation of the burning process without an external source of ignition, such as a flame or spark. This phenomenon often occurs during storage of such substances as hay, straw as well as coal or culm. Like any other type of fire, in addition to potential material losses, it also poses a threat to people. Thanks to the systematic monitoring of landfills...
