    Abstract From its beginning until today the Hungarian hydrocarbon industry has suffered more than seventy bigger accidents where intervention of the fire service and thorough examination was required. In the article the author presents the short analysis of accidents that were collected, systemized, and entered into database during the research, and their integration into the Geographic Information System (GIS). Based on the finished database, with the extended list of the locations’ GPS coordinates, the accidents will be entered into the ArcMap application. The publication of the accidents will be done with the help of Arcgis Viewer for Flex – Application Builder program. Following the GIS placement of accidents, testing, drawing conclusions and summarization are the main goals. The next step will be the preparation for assigning the database to the Disaster Management Decision Support Geographic Information System. Following the international publication, the long-term goal is the connection of each country’s files of dangerous industrial activities that were collected by researchers into one common database.

    Abstract One of the essential prerequisites for an efficient and effective organisation in our information society is the timely provision of information to the entitled person or persons. This is particularly important in the public, economic and business sphere, in public administration, law enforcement agencies and military operations as well. The information must always be available in the right place, at the right time, in the required quantity, quality and format, in order to gain and maintain the information superiority. This paper aims to analyse and present the methods of information sharing among different classified and non-classified systems and networks, their proposed areas of application, the security measures required for their safe implementation, and the risks and issues arising from their use. In this part of the article, the author analysed the different international security management procedures, the possible threats, vulnerabilities and solutions to create the most effective information-sharing environment.

    Abstract This work is motivated by a fine chemical industry task where n-propanol should be separated from its aqueous mixture. To accomplish this problem, the pervaporation process intends to apply PERVAP™ 1201 type dehydration membranes and to obtain information about the water removal from an aqueous mixture of n-propanol. Different evaluation parameters (selectivities, separation factors, and total fluxes) were experimentally determined. First in the literature, this binary system's Membrane Flash Index (MFLI) is also determined, confirming the efficiency of pervaporation against flash distillation. The experimental data from pervaporation measurements were evaluated with the improved model by Szilagyi and Toth. It has been established that the model can also be used for this case. The hybrid distillation and pervaporation system is rigorously modelled in a professional flowsheet environment (ChemCAD) and optimized with the dynamic programming optimization method. The distillation-based hybrid method without an extra added extractive agent for separating the n-propanol-water mixture has not yet been published in this computer program. The main objective functions of the hybrid method are the number of minimal theoretical stages and the minimal membrane area. It can be concluded that the process can dehydrate n-propanol with a purity of 99.9 percent.

    Abstract Nowadays, there is increasing interest in advanced simulation methods for desalination. The two most common desalination methods are multi-stage flash distillation (MSF) and reverse osmosis (RO). Numerous research works have been published on these separations, however their simulation appears to be difficult due to their complexity, therefore continuous improvement is required. The RO, in particular, is difficult to model, because the liquids to be separated also depend specifically on the membrane material. The aim of this study is to model steady-state desalination opportunities of saline process wastewater in flowsheet environment. Commercial flowsheet simulator programs were investigated: ChemCAD for thermal desalination and WAVE program for membrane separation. The calculation of the developed MSF model was verified based on industrial data. It can be stated that both simulators are capable of reducing saline content from 4.5 V/V% to 0.05 V/V%. The simulation results are in accordance with the expectations: MSF has higher yield, but reverse osmosis is simpler process with lower energy demand. The main additional value of the research lies in the comparison of desalination modelling in widely commercially available computer programs. Furthermore, complex functions are established between the optimized operating parameters of multi-stage flash distillation allowing to review trends in flash steps for complete desalination plants.

    Abstract Nitrogen is one of the most critical nutrients in the biosphere, and it is an essential nutrient for plant growth. Nitrogen exists in the atmosphere vastly as a gaseous form, but only reactive nitrogen is usable for plants. It is a valuable resource and worth recovering in the wastewater sector. The aim of this work was to prepare a comprehensive environmental analysis of a novel membrane contactor-based process, which is capable of highly efficient nitrogen removal from wastewater. Life cycle assessment (LCA), PESTLE and multi-criteria decision analysis (MCDA) were applied to evaluate the process. The EF 3.0 method, preferred by the European Commission, IMPACT World+, ReCiPe 2016 and IPCC 2021 GWP100 methods were used with six different energy resources-electricity high voltage, solar, nuclear, heat and power and wind energy.

    Abstract An aging society is a growing challenge for families, social and rehabilitation service providers, and economies. Information and communication technology-based assistive technology can bolster the independence of older adults (65 years and above) and reduce their burden on caregivers. Currently, there is no unified methodology to assess the effectiveness and acceptance of these technologies. The present study undertakes a scoping review to (1) identify and characterize the methods for assessing the acceptability and usability of information and communication technology-based assistive technologies, (2) explore the advantages and disadvantages of the assessment methods, (3) determine the possibilities of combining the assessment methods and (4) define the most commonly used assessment method and set of outcome measures. The literature was searched in MEDLINE, Scopus, IEEE Cochrane and Web of Science bibliographic databases using the keywords defined by reviewers for articles in English published between 2011 and 2021. Of the 1696 matches, 31 met the inclusion criteria. It was found that a combination of different assessment methods was common in outcome measurements. Of the 31 studies, assessment methods were combined in 21 studies and multiple questionnaires were used in 11 studies. The most common technique of outcome measurement was the use of questionnaires (81%), conducting interviews (48%) and recording usability-performance measures (39%). The advantages and disadvantages of the assessment methods could not be determined in the selected studies in this scoping review.

    Abstract Recycling and disposing wastewater from the pharmaceutical industry are of utmost importance in mitigating chemical waste generation, where unmanaged hazardous waste fluxes could cause massive environmental damage. Air stripping, steam stripping, distillation, and incineration offer significant emission reduction potentials for pharmaceutical applications; however, selecting specific process units is a complicated task due to the high number of influencing screening criteria. The mentioned chemical processes are modelled with the Aspen Plus program. This study examines the environmental impacts of adsorbable organic halogens (AOX) containing pharmaceutical process wastewater disposal by conducting life cycle impact assessments using the Product Environmental Footprint (PEF), IMPACT World + Endpoint V1.01, and Recipe 2016 Endpoint (H) V1.06 methods. The results show that the distillation-based separation of AOX compounds is characterized by the most favourable climate change impact and outranks the PEF single score of air stripping, steam stripping, and incineration by 6.3%, 29.1%, 52.0%, respectively. The energy-intensive distillation technology is further evaluated by considering a wide selection of energy sources (i.e., fossil fuel, nuclear, solar, wind onshore, and wind offshore) using PESTLE (Political, Economic, Social, Technological, Legal, Environmental) analysis combined with multi-criteria decision support to determine the most beneficial AOX disposal scenario. The best overall AOX regeneration performance and lowest climate change impact (7.25 × 10

    Abstract Human milk oligosaccharides (HMOs) are structurally complex unconjugated glycans that are the third largest solid fraction in human milk after lactose and lipids. HMOs are in the forefront of research since they have been proven to possess beneficial health effects, especially on breast-fed neonates. Although HMO research is a trending topic nowadays, readily available analytical methods suitable for the routine investigation of HMOs are still incomplete. NMR spectroscopy provides detailed structural information that can be used to indicate subtle structural differences, particularly for isomeric carbohydrates. Herein, we propose an NMR-based method to identify the major isomeric HMOs containing GlcNAc and/or Neu5Ac building blocks utilizing their amide functionality.
