In the last decades, many studies have been conducted on new materials to meet a growing industrial demand and to move scientific research forward. Superabsorbents are good examples of materials that have generated special attention in many fields for their ability to absorb and retain water up to 1000 times of their dry weight. They found many applications in hygiene products and other products, for a fast growing market of USD 9.58 Billion in 2019. Most of them are composed of synthetic polymers, which are often not environmentally friendly. Therefore, natural superabsorbents and particularly those based on polysaccharides have received a recent increased interest for their biodegradability, biocompatibility, and renewability. This review focuses on polysaccharide-based superabsorbents, on their properties, synthesis methods, and characterization. Their potential applications in many fields, such as biomedical and hygiene, agriculture, water treatment, and the building sector, are also reported with an interest in products already marketed.

The author outlines that the study of food design and film art as part of the country's ethnic culture examines the preservation and development of traditions and interethnic ties. Given that folk traditions have a peculiarity to develop, being in constant search of new solutions, taking into account the emergence of new materials, technologies and information tools, an idea to combine the potential of film art and food design in research has started up. It is noted that the search for analogues of the issue studied has no positive effect. The purpose of the study is a theoretical justification for the possibility of using different art forms as tools to unlock the possibilities and diversity of the art of food and filmmaking. Based on the study of various sources, it has been found that the topic of preserving the ethnic cultures of Russia is relevant and new, due to the unusual combination of the art of food and filmmaking. Hypothesis. It is suggested that the preservation and development of the country's ethnic cultures and intercultural ties is possible if best practices and achievements of food design as an essential part of people's culture will be applied while modelling different forms and spaces in film art. Results. Based on the results of the study, it can be concluded that the hypothesis put forward has historical evidence in the works of such scientists as: Kostomarov N.I., Orlovskaya A.V. and Pokhlebkin V.V. Based on their experience and knowledge the following is possible: formation of new approaches, serch for new solutions and development of new forms and spaces, using advances in food design, film art and people's culture.

In this research paper design and analysis of wire ropes used in elevator have been presented. The main objective of this study is to find the best practices on handling wire ropes for safety and to reduce the downtime of elevators due to wire rope failures. Design calculations have been done to calculate the apt dimensions and design is constructed on Auto Desk inventor software and the analysis have been performed using Ansys. Two configurations of the wire ropes have been studied and from this result it can be concluded that the design of wire rope is possible to relieve mechanical handling and to improve the design of wire ropes making it more durable by possible inclusion of new materials which in turn increases the efficiency and life of wire ropes without compromising safety.

This article relates history and various aspects of steam locomotive boilers and their relevance in present and future. Prior to 1950, boilers for steam locomotives were built in the United States using primarily lower carbon steel products. The Subgroup on Locomotive Boilers was formed in 2010. Four and a half years later, its work was published as Part PL, Requirements for Locomotive Boilers. The ASME’s Subgroup for Steam Locomotives has taken the approach of codifying both best practices and Code material from steam days. The new locomotive code, Part PL in Section I can truly be looked at as a beginning. New materials and methods will now have a place to be vetted within the unique perspective of steam locomotive operation so as to ensure safe steam locomotive boilers for centuries to come.

"Water represents the essence of life on earth, so we must preserve and use responsibly this given resource. For many years, water treatment has been a field of continuous development. At the same time, new materials and techniques are being developed for one of the most important methods in water treatment: Reverse Osmosis (RO). Actual technology in this domain provided us with good know-how to reverse osmosis systems creation, simulation, and validation of the simulation results. Our duty is to bring value to this heritage with new specific cases where the known techniques will be used to create efficient models for water treatment by reverse osmosis. Reverse osmosis is mainly a method for seawater desalination which started to be used more often in industrial applications for water and other product treatment. The focus of this study is to design and simulate a reverse osmosis system with the help of Q+ Projection software v3.1 for a 10 m3/h well water flow by using different types of membranes, in order to select an appropriate membrane which will provide the best parameters for permeate water. Permeate water resulted after reverse osmosis treatment will be used as process water for spirit drinks production. "

AbstractMembrane techniques for water treatment have been growing significantly for the last decade. Reverse osmosis, for example, is the leading seawater desalination technique. Nanofiltration membranes are used more and more for hardness removal and even to desalinate slightly polluted waters. Ultrafiltration and microfiltration membranes are used extensively mainly as membrane bioreactors in wastewater recovery. While this trend is growing, the membranes still may be improved significantly, based on new materials designed to increase the flux of water through the membranes at reduced pressures while maintaining or even improving the rejection of dissolved matter or suspended matter. Better membranes will reduce energy consumption while maintaining affordable separation properties.

This paper proposes the knowledge development of the crisis management taking place in the largest drinking water treatment system in Thailand, with the capacity of approximately 4,000,000 CMD. The system encountered with the flood crisis six years ago. Having drawn back to 2011, the flood crisis had massive impact on Metropolitan Waterworks Authority (MWA). For examples, many water treatment processes were disrupted, consumers were not confident on the drinking water quality, and additional operation cost of MWA was raised up about 300 million baht, etc. Therefore, it is an importance to have mitigation measures for the organization to reduce the risk by increasing the capacity of the community and cooperating with the stakeholders to cope with the risks by applying well planned and well-executed in Disaster Risk Reduction (DRR) and Crisis and Emergency Risk Communication (CERC). The result shows the development opportunities of the Metropolitan Waterworks Authority in various aspects from past experiences, and proposes the best practices in order to response with all stakeholders when risks encountered.

Microstructural Studies

After materials with superconducting temperatures higher than liquid nitrogen have been prepared, more emphasis has been on increasing the current densities (Jc) of high Tc superconductors than finding new materials with higher transition temperatures. Different processing techniques i.e thin films, shock wave processing, neutron radiation etc. have been applied in order to increase Jc. Microstructural studies of compounds thus prepared have shown either a decrease in gram boundaries that act as weak-links or increase in defect structure that act as flux-pinning centers. We have studied shock wave synthesized Tl-Ba-Cu-O and shock wave processed Y-123 superconductors with somewhat different properties compared to those prepared by solid-state reaction. Here we report the defect structures observed in the shock-processed Y-124 superconductors.
