The developed model enables the application of soft mathematics technology to make reliable decisions related to the field of business of the military process industry. Using the method of analogy, the developed model for optimal process industry management can be used for systems in other areas as well. Unlike various models that were developed before the covid-19 pandemic, this model puts the health safety factor in the first place in terms of evaluation.With the appearance of the covid-19 pandemic, a security factor in the military industry, and above all the process is further complicated, and thus the system optimization of management. The paper shows the possible application of the model on a specific production system in the field of military process industry. Research shows that at all levels of management in the conditions of the covid-19 pandemic, there was no systematic approach to management optimization in which the safety factor is in the first place.Successful modeling of such complex systems is not possible without the application of multidisciplinary knowledge such as: engineering-technical, medical-health, security, economic, socio-psychological, educational and soft mathematics. In the education system, developmental changes are needed in the function of educating a larger number of staff who possess multidisciplinary knowledge.","PeriodicalId":111112,"journal":{"name":"Proceedings of the 34th International Congress on Process Industry","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122155301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The structure of cationic starch derivatives was characterized by using Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). The properties of materials such as cationic degree, viscosity, swelling capacity, solubility and moisture content were determined according to standard methods. The degree of cationization of the prepared cationic starches varied from 0.048 to 0.162 mmol g-1for samples with GTMAC and from 0.032 to 0.156 mmol g-1for samples with BHC.

The content of paraffin in oil has a dominant influence on the properties of paraffin oil, and in particular has an impact on the reduction of the flow properties of the oil. Oil heating improves the flow properties, reduces the viscosity, as well as the losses of pressure on the friction when transporting pipes. The physical properties of crude oil are modified by heating to prevent the formation of wax inside the oil pipeline. Based on experimental and theoretical research on the real oil pipeline, simulation using the Origin software, the influence of the change in the temperature of heating crude oil, viscosity and flow, pressure drop and pump power was analyzed. Depending on the paraffin content, the oil is heated to the appropriate temperature before being introduced into the pipeline. The starting temperature of the oil depends on the paraffin content and the pour point. The case of heating oil to a temperature of 20 ‒ 50 oC was considered. The cooling rate during oil transport is (0,52 ‒ 0,55) oC / h. When transporting domestic paraffin oil, the downtime should not be longer than 24 hours, because due to standing and cooling, solid paraffin particles would appear, and then the oil would gelation in the pipeline. With a decrease in temperature Δt = 10 oC and a consequent increase in viscosity, there is a noticeable increase in pressure drop by 3 ‒ 4% and that requires more pump power.","PeriodicalId":111112,"journal":{"name":"Proceedings of the 34th International Congress on Process Industry","volume":"150 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128872918","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Amino-modified lignin microspheres (LMS-NM) were synthesized via inverse suspension copolymerization of kraft lignin with poly(ethylene imine) grafting-agent and epichlorohydrin cross-linker. The porous structure of the synthesized adsorbent was formed using a 5.0 wt.% sodium-alginate solution. Additional efficiency in the removal of chromium anions from water was achieved by functionalization of lignin microspheres with magnetite (NM) nanoparticles obtained by co-precipitation and additional introduction of amino groups. Structure of formed LMS-NM was confirmed via Furrier Transform Infrared (FTIR) Spectroscopy. Optical microscopy analyses showed the creation of sphere-shaped materials and showed the diameter of prepared LMS-NM in the range of 500 to 800 µm. The removal of chromate anions from water solution was performed in a batch system. The result confirmed high adsorption efficiency and potential application of this nature-based adsorbent for heavy metal anions removal.

Samples of packaging for food products and samples of garden hoses were tested, for which, based on the imprinted identification/recycling code i.e., the manufacturer's specification, it was assumed that they were made of polymer materials based on PVC. It was assumed that by applying the burning test, a preliminary identification of PVC types from which the tested samples were made could be performed. It is also assumed that the presence of additives in PVC-based plastics significantly affects the burning behavior of samples. The obtained results suggest / preliminary confirm that the samples of butter packaging containers are made of rigid PVC. The presence of an additive in the rigid PVC interferes with the behavior of the samples in the open flame during the burning test. Based on the results of the burning test, it can be estimated (preliminarily identified) that the samples of garden hoses are made of flexible PVC. The burning test represents a fast method of identification of PVC-based polymer materials, which enables preliminary differentiation of flexible and rigid PVC in recycling packaging plants and polymer processing plants.","PeriodicalId":111112,"journal":{"name":"Proceedings of the 34th International Congress on Process Industry","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133262897","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Effects of its presence can easily be noticed and felt. As technology moves forward, organizations experiment with ways to solve problems using Artificial Inteligence. Openness to change can be one of the most important advantages for organizations in near future. In the beginning of the paper, it will be explained how techniques of Artificial Inteligence can influence quality management processes in an organization, in parallel with analysis of relation between Artificial Inteligence Techniques and Deming’s PDCA cycle. As an example, use of artificial techniques in service quality management processes in hotels will be shown in this part of the paper. Standardization in Artificial Intelligence is a hugely important topic in this paper. The goal of Standardization in Artificial Intelligence is to enable the right ways to exploit the good side of Artificial Inteligence’s potentials. Speciffically, this paper will focus on BS 8611:2016, for ethical design and application of robots and P7001, for transparency of Autonomous Systems. As a conclusion to the paper, authors analysed the possibilities for improvement, not only for improvement of quality of products and services, but of quality of an organization itself, using Artificial Inteligence techniques.
