The modern world faces challenges related to the necessity of sustainable development, improving the quality of life for citizens, and reducing the negative impact of human activities on the environment. Transport, as one of the key sectors of the economy, plays a significant role in shaping modern societies. At the same time, it is a source of num...

Improving the level of accessibility of integrated interchanges and providing free movement forpeople with special needs is one of the currently most important transport issues raised by a numberof centres. Over the last two decades, several attempts have been made to develop solutions toenhance mobility, e.g. more links between destinations, openi...

The equipment of airport security screening checkpoints undergoes frequent modifications due to technological or organizational changes. New solutions complement or replace existing ones to improve the effectiveness of the equipment or formal requirements. An example of this process is the replacement of the walk-through metal detection gate with a...

The development of airport security screening systems requires the use of increasingly sophisticated and effective equipment to detect prohibited or hazardous items and substances. However, this can lead to a reduction in the throughput of the security checkpoint (SCP). This paper addresses the operationally important problem of the dilemma between...

The Scientific and Analytical Report presents policy recommendations for national and regional authorities in Ukraine regarding the development of multimodal terminals and the experience of implementing the European Green Deal by the V4 countries and Romania. In particular, the institutional framework for the implementation of the European Green D...

In recent years, efforts have been observed aimed at improving the functioning of passengers in the area of integrated transfer hubs. An analysis of literature sources and legal requirements has pointed to a lack of legal regulations in the field of public transport. The absence of guidelines concerns both modes of transport and infrastructure elem...

Transportation accessibility for people with disabilities is the challenge of our time. In Poland, there are more than 3 million people with disabilities who have legal proof of disability. In reality, there are many more - from 4 to as many as 7 million. Thus, there is a need to actively include this group of people in social life, including in th...

This paper presents an analysis of the costs, failure rate, vulnerability, and safety of electric, hybrid, and internal combustion vehicles (EV, HEV, and ICEV), including a review of literature sources, calculations, and investigations. Many literature sources do not provide information on maintenance costs (including repairs and servicing) and lim...

The analytical report presents the results of the study of international and transit cargo flows across the Ukraine-EU border section. An analysis of the development of transport (roads, railways, international transport corridors, including TENT) and border infrastructure (network of checkpoints, terminals for storage and transshipment of goods, l...

As the number of electric and hybrid vehicle users increases, there is growing interest in the topic of maintenance and servicing costs. Many literature sources do not provide information on this topic and only limit themselves to energy costs. However, it is not just energy costs that make up the total cost of owning such a vehicle. What is missin...

Mineral resources form the basis of production in the metallurgical, electrical, chemical, construction, ceramic and glass industries, as well as in other industries. However, they are still non-renewable and depletable raw material resources, which also have restrictive uses due to their uneven geological and geographical distribution. Manufacturi...

The transport process consists of many stages, where many interferences and problems may occur. It is important to identify these problems and find solutions to them, for example, using innovative tools supporting transport process management. A properly organised transport process allows the entire supply chain to function properly. For a transpor...

In recent years, the development of IT systems for fleet monitoring was observed. Tire pressure monitoring systems are constantly improved. Decreased values in tire pressure can cause deformation of tires. Monitoring of tire pressure is an important function in oversized transport trucks. Tire pressure and rolling resistant influence fuel consumpti...

With a few works in 2010 on the application of carbon nanotubes (CNTs) in wind turbine blades (WTBs), new hopes have arrived promising to conquer the so-far used materials. From that moment, several dozens of publications have been published confirming that CNTs – typically considered as ‘universal soldiers’ in the composite, hybrid and hierarchica...

The aim of this paper is to present characteristics, toxicity and environmental behavior of nanoparticles (NPs) (silver, copper, gold, zinc oxide, titanium dioxide, iron oxide) that most frequently occur in consumer products. In addition, NPs are addressed as the new aquatic environmental pollutant of the 21st century. NPs are adsorbed onto particl...

The sorption of Cu(II) ions onto natural (clinoptilolite) and synthetic (Na-X and Na-P1) zeolites was investigated. The synthetic zeolite samples were obtained from coal fly ash under hydrothermal crystallization conditions. The following issues were studied under batch conditions: the influence of the initial concentration of the Cu(II) ions, dose...

The aim of this study was to determine the adsorption capacity of the smectite clays (from the overburden of the lignite deposit in Belchatow) for two anionic dyes, i.e. Reactive Blue 81 (RB-81) and Direct Blue 74 (DB-74). Additionally, the influence of the thermal and chemical (acid and alkali) clay modifications on the amount of bonded dyes was i...

Four acid dyes were adsorbed on lignite (porosity 0.6335) from aq. solns. at initial concns. 1-1000 mg/L under static conditions. The lignite was an efficient sorbent (capacity 3.8-22.7 g/kg). The process was successfully described by Langmuir, Freundlich and Dubinin-Radushkevich isotherm equations.

Sorption capacities of low-moor peats and Neogene clays from the overburden of lignite beds in Central Poland for Cr(III) ions as chloride and metalorganic complex ions have been investigated. The binding mechanisms and sorption parameters were determined based on the Freundlich and Langmuir nonlinear sorption isotherms. The sorption capacities of...
