Preventing pathogenic viral and bacterial transmission in the human environment is critical, especially in potential outbreaks that may be caused by the release of ancient bacteria currently trapped in the permafrost. Existing commercial disinfectants present issues such as a high carbon footprint. This study proposes a sustainable alternative, a bioliquid derived from biomass prepared by hydrothermal liquefaction. Results indicate a high inactivation rate of pathogenic virus and bacteria by the as-prepared bioliquid, such as up to 99.99% for H1N1, H5N1, H7N9 influenza A virus, and Bacillus subtilis var. niger spores and 99.49% for Bacillus anthracis. Inactivation of Escherichia coli and Staphylococcus epidermidis confirmed that low-molecular-weight and low-polarity compounds in bioliquid are potential antibacterial components. High temperatures promoted the production of antibacterial substances via depolymerization and dehydration reactions. Moreover, bioliquid was innoxious as confirmed by the rabbit skin test, and the cost per kilogram of the bioliquid was $0.04427, which is notably lower than that of commercial disinfectants. This study demonstrates the potential of biomass to support our biosafety with greater environmental sustainability.

The article presents data on the effective use of secondary saline irrigated land in Almaty oblast. The use of salt-resistant phytomeliorants and an adoptogen contributed to a decrease in the salt content in the soil, along with an increase in yield and improvement of the soil structure. The results showed that in the upper layers of the soil (0-20 cm), the content of agronomically valuable aggregates is higher and ranges from 64 to 73%, and with a depth (20-40 cm) it decreases and ranges from 39 to 66%. The content of water-bearing aggregates increases by 2-5% with depth, and the volume mass of the soil increases with depth and averaged 1.24-1.30 g/cm3. The humus content ranges from 0.54 to 1.16%. The results of observations of the growth and development of phytomeliorants showed that phytomeliorants intensively grew, developed and accumulated aboveground masses, especially in variants with adaptogen treatment. The height of plants reached up to 266 cm (Sudan grass), and on the variant without treatment was 257 cm. Accumulated aboveground masses from 950 to 2013 gr. Intensive growth of phytomeliorants was suppressed by weeds, and their contents were insignificant from 19 to 22 pcs/m2, and in the variant with adaptogen treatment was from 18-20 pcs/m2. The average yield of sorghum green mass ranged from 740.4 centner/ha in the variant without adaptogen treatment, and in the variant with treatment was 777.4 centner/ha. The average yield of sudan grass was 947.0-990.3 centner/ha, and soybean seed yield was in the range from 54.7-56.4 centner/ha. Intensive development of phytomeliorants contributed to an increase in yield and a decrease in salts on the upper soil horizon (0-20 cm) from 0.06 to 0.27%. The largest decrease in salts by 0.27% was observed under soybean crops. The use of the recommended technology contributed to saving irrigation water up to 70% due to drip irrigation, reducing the cost of washing and chemical reclamation – gypsum.

Due to the rise in environmental awareness, corporate companies have shifted their focus from an obsession with short-term profits to contemplating long-term strategies to achieve sustainable management. Effective use of resources is the primary indicator of this achievement. Fulfillment of corporate social responsibility and thinking beyond the regulatory aspects of corporate sustainable management are goals that have continually attracted attention worldwide. Material flow cost accounting based on ISO 14051, which was announced by the International Organization for Standardization (ISO), is a tool that can be used to achieve a balance between the environment and economy. We focused on using ISO 14051-based material flow cost accounting as an analytical evaluation tool from the perspectives of finance and accounting personnel. We conducted a case study on a flat-panel parts supplier to determine whether the efficient use of recycled glass could reduce company costs. The primary finding is that the film layer on recycled washed glass tends to be stripped during the production process, causing increased reprocessing costs and thus rendering the cost of renewable cleaning higher than that of reworking. This study revealed that the ISO 14051-based material flow cost accounting analysis constitutes a valuable management tool, thereby facilitating the promotion of sustainable development.

Aircrafts are responsible for a significant environmental impact mainly due to the air pollution caused by their motors. The use of composite materials for their production is a way to significantly reduce the weight of the structures and to maximise the ratio between the payload weight and the gasoline consumption. Moreover, the design phase has to consider the cost of different operations performed during the aircraft service life. During the entire life cycle, one of the main costs is the maintenance one. In the current literature, there is a lack of knowledge of methods for maintenance cost estimation in the aircraft industry; moreover, very few environmental assessment methods have been developed. Thus, the aim of this paper is to define a new method to support the aircraft design process; both the environmental and the economic dimensions have been included with the purpose of assessing the aircraft sustainability during its service life. A green index has been identified mixing the maintenance cost and an environmental parameter with the aim of identifying the greenest solution. A final practical application shows the feasibility and the simple application of the proposed approach.

In addition to data and record handling and the completion of complex and arduous mathematical calculations, the computer may serve a wide range of purposes for the agricultural industry; these include the provision of day-to-day management information, the mechanical enactment of management decisions, business forecasting, interpretation of real life and prediction of future response by use of simulation models, analysis of cost effectiveness of various tactics and stratagems, the transfer of information, scrutinization of existing knowledge and the formulation of experimental programmes. The computer is seen as a major linking medium between research, development and production practice; being both the preferred route for information flow and an ideal way of packaging dispersed pieces of knowledge into practical, usable, systems advice.The concern of practical producers is not with discrete little problems but with systems. To help, the extension worker must bring forward systems solutions. Often research and development workers try to get across to producers potential benefits in small bits (3 times daily milking gives a yield lift of 15%; flat rate feeding gives better margins over concentrates; high density diets improve feed efficiency), whereas producer benefits come from the cost effectiveness of whole integrated systems.

The paper shows that in the conditions of a deficit of high-quality metal charge in steels melting production, the effective use of waste from abrasive grinding in the composition of the metal charge is a promising method for reducing the cost of steel. The most rational solution for the disposal of metallurgical wastes may be the agglomeration of fine-grained and fine-dispersed materials using briquetting technology widely used in many countries around the world to produce multi-purpose briquettes.

The subject of the article is to give a full analysis of the cascade type layouts in elements strengthening design in bending by gluing the fiber reinforced polymer (FRP) materials on their surfaces’ applicability and effectiveness. The research objectives are the substantiation elements cascade method application reinforcement with adhesive joints. Materials and methods are revealed in a few variants of FRP-reinforcement with application of FEM simulation. A number of diagrams and tables represent the results. The results are defined in the cost-effective efficient method presentation of the bent elements strengthening to increase their bearing capacity reserves, the features of the bonded joint behavior, the equations and formulae for the glue joint analysis and design. Conclusions are formulated in depicting the “cascade” reflects, the features of the proposed strengthening design, the base element unloading, which is gradual with each successive element attached. The design examples are oriented on the adhesive joints’ application possibility analysis of attaching the FRP elements. The results suggest the effective use possibility of the adhesive joints to strengthen rather stiff, including steel, elements in bending. The cascade method eliminates the indispensability of highly expensive high-strength materials, thereby reducing the reinforcement structures cost.

Biologics play a key role in cancer treatment and are principal components of many therapeutic regimens. However, they require complex manufacturing processes, resulting in high cost and occasional shortages in supply. The cost of biologics limits accessibility of cancer treatment for many patients. Effective and affordable cancer therapies are needed globally, more so in developing countries, where health care resources can be limited. Biosimilars, which have biologic activity comparable to their corresponding reference drugs and are often more cost effective, have the potential to enhance treatment accessibility for patients and provide alternatives for decision makers (ie, prescribers, regulators, payers, policymakers, and drug developers). Impending patent expirations of several oncology biologics have opened up a vista for the development of corresponding biosimilars. Several countries have implemented abbreviated pathways for approval of biosimilars; however, challenges to their effective use persist. Some of these include designing appropriate clinical trials for assessing biosimilarity, extrapolation of indications, immunogenicity, interchangeability with the reference drug, lack of awareness and possibly acceptance among health care providers, and potential political barriers. In this review, we discuss the potential role and impact of biosimilars in oncology and the challenges related to their adoption and use. We also review the safety and efficacy of some of the widely used biosimilars in oncology and other therapeutic areas (eg, bevacizumab, darbepoetin, filgrastim, rituximab, and trastuzumab).
