Climate Change and Innovation in Brazil- Threats and Opportunities

In recent decades, Brazil has adopted a political approach focused on maintaining economic stability and consolidating inclusive social policies. However, despite repeated attempts, little progress has been made in overcoming difficulties within the country and making Brazil more competitive in the global market. Nevertheless, there seems to be an awakening and a certain consensus among scholars of Brazilian problems that the expected inclusive economic growth cycle may be achieved if Brazil invests in enhancing the bioeconomy business environment through bioenergy and innovation. The actual crisis is fast–tracking two major transformations at the global level: the energy transition and the information revolution, both dependent on innovation. Brazil showcases a comparative advantage for renewable energy sources in comparison to the rest of the world. Even considering the controversial major use of hydroelectricity and sugarcane biofuels, these sources are undoubtfully less harmful than fossil sources, such as coal and diesel. This could be an unprecedented opportunity. Nevertheless, Brazil has faced considerable environmental disasters in recent years, despite its consistent legal framework protecting the environment. This paper advocates a legal pathway to disseminate knowledge and to reach sustainable growth by adopting decarbonization processes and innovation. By decarbonization processes, the authors mean the transition to a decarbonized economy by adopting innovative technological transformations that provide bioeconomy lead traditional manufacturers into renewable and sustainable industries. In relation to these processes, it is essential that decision makers, especially public officials in the national environmental and innovation agencies, understand the existing legal paths, modernize the instruments used for cooperation and the generation of new products with a focus on growth and competitiveness, and enforce environmental protection law and mechanisms. Regarding innovation, the premise is that the new cooperation instruments allowed by the legal framework of innovation will strengthen relations between public and private agents. This paper first presents the principles and main environmental and energy transition rules that comprise the current Brazilian legal framework. It then shows the contradictions that need to be overcome in the environmental system. Finally, the paper presents opportunities and proposals for change and improvement towards sustainable growth. and

Adaptive decision-making method of life cycle options by using process data collected over multiple life cycle stages

The appropriate design of product life cycles is crucial for the realization of a sustainable society. Since Alting proposed the concept of life cycle engineering in 1993, many concepts, approaches, methods, and tools have been proposed and developed for the purpose. On the other hand, rapid development of Internet of Things (IoT) technology enables the development, operation, and maintenance of a new generation of products: so-called ‘smart’ products. One characteristic of smart products is the use of data collected throughout the product’s entire life, making it possible to improve energy and resource efficiency. In this context, many efforts have been devoted to developing a variety of algorithms, methodologies, and data models for supporting IoT-enabled engineering activities such as maintenance, production planning, and logistical planning. However, there exists a gap between life cycle engineering and emerging IoT-based technologies; that is to say, little research has addressed the life cycle design of products (including end of life treatment stages) using IoT-based technologies, whereas most IoT-based research focuses on improvement of individual life cycle stages such as production, operation, or maintenance. It is not currently clear how IoT-based technologies can practically contribute to the adequate design of product’s life cycle as a whole. As a first step toward answering this question, this paper proposes a process data model that captures the complex interdependency of product data over multiple life cycle stages. We additionally present a method based on this data model for determining a product’s appropriate life cycle options. Finally, through an illustration of the method with a simplified case study, we discuss the advantages and the future development needs of IoT-based life cycle design.

Additive technology to create a tool for electroerosive processing

The paper considers new methods and tools for combined electroabrasive finishing of metal parts, and shows the advantages of such a tool over traditional methods of finishing shaping the surfaces of labor-intensive products made of difficult-to-process alloys. The possibilities of layer-by-layer application of materials using additive technology to reduce labor intensity and cost for combined processing of tools with layers of abrasive on the periphery of a metal body obtained from a low-melting alloy by the additive method are considered. The possibility of accelerated production of tools using this technology, which does not require significant costs for editing and sharpening for specific parts, is shown, which reduces the production time of technological equipment when launching new generations of products, primarily in the aerospace industry of mechanical engineering. The new method and design of the tool are protected by a Russian patent. Experimental operation of wheels made using additive technologies has shown that the use of such a tool in single and small-scale flexible structure production significantly reduces the complexity of manufacturing parts for finishing operations.

Обогащение продуктов питания – современный принцип пищевой индустрии

Aim. To analyze the scientific and technical literature and identify ways to create a new generation of mass-consumption food products enriched with vital nutrients. Discussion. The main malnutrition of the Russian population is the excess of caloric intake over an indicator of the level of energy consumption. One of the ways to solve this problem is the production of functional food products or enriched functional products. The essence of this is that only those micronutrients that are really in short supply should be used in the fortification of products. These should be products of mass consumption, and especially those that undergo refining, which results in the loss of micronutrients. The use of raw materials and ingredients only of natural (animal, vegetable, mineral) origin, allows you to create active complexes that qualitatively change the physiological properties of the product, and can affect many product characteristics and processes such as physico-chemical, structural-mechanical and organoleptic characteristics of the product, the processes of color formation, fermentation, oxidation, storage capacity. However, sometimes a strong passion for enriching the product with useful macro- and micronutrients affects the taste characteristics. Conclusion. When developing recipes and technologies for new-generation products, it is necessary that the enrichment of the product with important and necessary elements does not worsen the organoleptic characteristics. At the same time, it is necessary to ensure the safety of products without compromising consumer properties. The diet should contain all the necessary nutrients (nutrients) for a person in sufficient quantities and balanced with each other in the most favorable proportions.

Enrichment — the way to create a new generation of food products

The main dysnutrition of the Russian population is the excess of caloric intake over an indicator of the energy consumption level. One of the ways to solve this problem is the production of functional food products or enriched functional products. The essence of this is that only those micronutrients that are really in short supply should be used in the fortification of products. These should be products of mass consumption, and especially those that undergo refining, which results in the loss of micronutrients. The use of raw materials and ingredients only of natural (animal, vegetable, mineral) origin allows creating active complexes that qualitatively alter the physiological properties of the product and can affect many product characteristics and processes such as physico-chemical, structural, mechanical and organoleptic characteristics of the product, the processes of color formation, fermentation, oxidation, and storage capacity. However, sometimes a strong passion for enriching the product with useful macro- and micronutrients affects the taste characteristics. Therefore, when developing recipes and technologies for new-generation products, it is crucial that the enrichment of the product with important and necessary elements should not deteriorate the organoleptic characteristics. At the same time, it is essential to ensure the safety of products without compromising consumer properties. The diet should contain all the nutrients necessary for a person in sufficient quantities and balanced with each other in the most favorable proportions

Dairy by-products: characteristics and modern ways of utilization

The unique composition of milk makes this foodstuff an exceptional raw material for the production of new ingredients with good functional properties and the possibility of a various applications in the food industry. Therefore by-products of the milk industry that arise in special technological processes have great importance and application in the production of new generations of ingredients. Fractionation of milk is very important in the development of these products, so it was necessary to make a whole series of studies in this field, especially regarding different levels of fractionation and separation of certain milk constituents during filtration processes. This review is based on the presentation of basic characteristics of by-products which are produced during milk processing, such as whey, skim milk, buttermilk and permeate, and many possibilities of their application. Wide range of products based on dairy byproducts has been produced. Whey proteins and caseins are protein fractions which are excellent emulsifiers and protein supplements. Furthermore, they can be chemically or enzymatically modified in order to produce bioactive peptides with numerous functional and nutritional properties. In this context, techniques that enable more complete utilization of total milk proteins are being developed. Generally, proteins as important part of dry matter of by-products represent an economic and environmental problem if they are not utilized. Phospholipids originating from milk fat are excellent emulsifiers and also known as food components that exhibit excellent pharmacological activity (nutraceutical properties). In addition, the enzymatic modification of milk phospholipids makes it possible to obtain the emulsifiers with the desired functional properties. As dominant component of the dry matter of milk, lactose also has a whole range of good functional properties and allows different types of fermentations depending on the applied starter culture. Therefore it has great application in the food industry. Refined lactose is characterized by a high degree of purity, chemical and physical stability, and as such, it is applied in the pharmaceutical industry as a filler and inert tablet carrier. Also lactose can be used in the chemical industry. However, there are few more aspects to overcome, such as deeper understanding of functional and nutritional properties of these new ingredients that might be barrier for their use and acceptability. In addition, the possibility of using different components of milk dry matter in other industries, such as in the production of plastic materials, paints, textile fibers, etc., are presented in this review. New trends in nutrition, requirements for minimum processed food, ecological aspect of food production are the dominantfactors that have imposed the need for innovative approaches in creating new food products. All of the above have influenced dairy industry in order to expand the diversity of dairy products which meets the needs of the modern consumer, such as low fat and fat free milk products, high protein content products, fortified products with the addition of minerals, vitamins, etc., probiotic and prebiotic dairy products, low lactose and lactose free products, and others. All this points to the innovation potential of dairy by-products, which provides great opportunities for research and the possibility of their application in the processing of milk and dairy products.

New micronutrient biocomponents based on blackcurrant seeds pomace – Bench-scale kinetic studies

In the present work new universal bench-scale plant for biosorption, useful in production of new micronutrient biocomponents, was described. The new installation enabling working in a fixed bed or stirred tank batch mode. Reactors may also be used in serial or parallel mode, which gives many application possibilities. Copper ions were selected as a sorbate for kinetic modelling. The results of the adsorption capacities of Cu(II) were 13.9 mg/g for fixed bed and 12.8 mg/g for stirred tank. During biosorption of Cu(II) ions from aqueous solution ion exchange and release of Ca(II), K(I), Mg(II), and Na(I) were observed. For kinetics description of stirred tank process pseudo-1st-and pseudo-2nd order models were used. For fixed bed process the Thomas, Yoon-Nelson, Adams-Bohart and Wolborska models were used. The use of blackcurrant seed residues as biosorbents enables the generation of new products from waste biomass, which can become an alternative to the traditional fertilizers with microelements. The presented technology is an attempt to reduce environmental impact of the conventional micronutrient fertilizers, which contain toxic chelators such as EDTA. Minimization of waste and maximization of product output makes it an efficient tool supporting cleaner production.

Considerations Regarding the Role of Fortification Infrastructure Used for General Protection of the Romanian Armed Forces, Public Administration Authorities and Civil Population During Crisis Situations

Abstract The physiognomy of the combined operations recorded essential changes at the beginning of the 21st century, due to the impact of the scientific and technical revolution in the military field, materialized in the production of new generation’s weapons with particularly destructive characteristics (Vladu & Popa, 2016). The emergence of new advanced capabilities for conducting air operations, as well as the use of military robots and intelligent ammunitions in joint operations led to the implementation of the “lightning success” concept by the forces of modern armies. In this respect, we consider that a particularly important role in achieving “lightning success”, by the forces of the modern armies, is played by the main characteristics of adversary general protection system, particularly by the weaknesses of the fortification system which have not been able to provide optimal conditions for protection for the command and control systems, fighting and supporting forces, as well as for public administration authorities and the civilian population.

Ecological panels as an alternative for waste from mechanical processing of Amazonian species

The wood residues resulting from the operational phases in companies in the forestry market are normally considered by-products and, therefore, are discarded or reused for energy production, however, this material has a greater potential, such as the generation of new products through agglutination, which may generate a new segment in the wood industry, causing competition between products of native and planted species. This research aimed to develop agglomerated panels using residues of two tree species from the Amazon (Dinizia excelsa Ducke and Manilkara huberi (Ducke) Chevalier) and a mixture of commercial Amazonian species of high density, with the purpose of greater added value and a possible solution to reduce the negative environmental impacts of carbon emissions. The experimental design consisted of three treatments with five repetitions in each. Experimental panels were produced with a nominal density of 0.80 g/cm³, using castor oil-based resin with 10% percentages. The panels were pressed with a pressure of 10 MPa, temperature of 100ºC and with a pressing time of 10 minutes. The evaluations of the results obtained were compared with the ANSI A208.1 / 2009 standard and with the literature on agglomerated panels of tropical species. In physical properties, the panels showed compliance with the values found in the literature, however, they are outside the standard of the norm. Regarding the mechanical properties, the MOR values classify the panels in the medium to high density standard in accordance with the standard. The results of the MOE are superior to those of the existing literature, with emphasis on the perpendicular traction that presents values consistent with the literature. The machining evaluations carried out according to ASTM D 1666-11 / 2011, show a good quality in the finish. In general analysis and in compliance with the regulations, all panels have economic viability and potential for industrialization.

Robust multiperiod inventory model considering trade-in program and refurbishment service: Implications to emerging markets

We propose a closed-loop supply chain system that incorporates a trade-in program and refurbishment service simultaneously. Through the trade-in program, retailers collect used old-generation products from customers and provide them with new-generation products at a discount price. It helps to acquire the additional products required for the refurbishment service. The proposed integrated system could be useful to retailers selling the smartphone which has a high potential in emerging markets. We approximate the multistage stochastic optimization model to the robust counterpart which features a second-order cone program. Computational results provide managerial insights that could be beneficial to the retailer.

Spectral harmonization and red edge prediction of Landsat-8 to Sentinel-2 using land cover optimized multivariate regressors

Multi-sensor remote sensing applications consistently gain importance, boosted by a growing number of freely available earth observation data, increasing computing capacity, and increasingly complex algorithms that need as temporally dense data as possible. Using data provided by different sensors can greatly improve the temporal resolution of time series, fill data gaps and thus improve the quality of land cover monitoring applications. However, multi-sensor approaches are often adversely affected by different spectral characteristics of the sensing instruments, leading to inconsistencies in downstream products. Spectral harmonization, i.e., the transformation of one sensor into the spectral domain of another sensor, may reduce these inconsistencies. It simplifies workflows, increases the reliability of subsequently derived multi-sensor products and may also enable the generation of new products that are not possible with the initial spectral definition. In this paper, we compare the effect of multivariate spectral harmonization techniques on the inter-sensor reflectance consistency and derived products such as spectral indices or land cover classifications. We simulated surface reflectance data of Landsat-8 and Sentinel-2A from airborne hyperspectral data to eliminate any sources of error originating from unequal acquisition geometries, illumination or atmospheric state. We evaluate different methods based on linear, quadratic and random forest regression as well as linear interpolation, and predict not only matching but also unilaterally missing bands (red edge). We additionally consider material-dependent spectral characteristics in the harmonization process by using separate transformation functions for spectral clusters of the input dataset. Our results suggest that spectral harmonization is useful to improve multi-sensor consistency of remote sensing data and subsequently derived products, especially if multiple transformation functions are incorporated. There is a strong dependency between harmonization performance and the similarity of source and target sensor's spectral characteristics. For spectrally transforming Landsat-8 to Sentinel-2A, we achieved the lowest radiometric inter-sensor deviations with 50 spectral clusters and linear regression. Based on simulated data, deviations are below 1.7% reflectance within the red edge spectral region and below 0.3% reflectance for the remaining bands (RMSE). Regarding spectral indices, our results show a reduction of inter-sensor deviation (vegetation pixels only) to 38% of the initial error for NDVI (Normalized Difference Vegetation Index) and to 43% for EVI (Enhanced Vegetation Index). Furthermore, we computed the REIP (Red Edge Inflection Point) with an accuracy of 3.1 nm from Sentinel-2 adapted Landsat-8 data. An exemplary multispectral classification use case revealed an increasing inter-sensor consistency of classification results from 92.3% to 97.3% mean error. Applied to time series of real Landsat-8 and Sentinel-2 data, we observed similar trends, albeit intermingled with non-sensor-induced inconsistencies.

Death by waste: Fashion and textile circular economy case

In a circular economy model the way we use the textiles needs to change at a fundamental level. A circular economy is an alternative to a traditional economy (fabrication, use and dispose) in which we keep resources in a loop for as much time as possible, try to maintain their value while in use, and repurpose for generation of new products at the end of utilization. The value of the global fashion industry is 3000 Billion dollars that accounts for more than 2% of the world's Gross Domestic Product (GDP) (https://fashionunited.com/global-fashion-industry-statistics/). In the last two decades not only the textile industry has doubled the production but also an average global annual consumption of textiles has doubled from 7 to 13 kg per person and reached to the threshold of 100 million tonnes of textiles consumption. More than two thirds of the textile goes to landfill at the end of their use and just around 15% is recycled. Various scientific studies confirm that the disposal nature of fast fashion and throwaway culture is resulting in a serious environmental, health, social and economic concern. One of the global environmental challenges arising from micro-plastic and micro-textile waste entering into the oceans that can end up in fish and eventually food chain. Herein, through a systematic literature review, the significance of circular fashion and textile is highlighted and various approaches for reuse, recycle and repurposing of the textiles waste as well as disruptive scientific breakthroughs, innovations and strategies towards a circular textile economy have been discussed. Looking into the future, remarks have been made in regards to tackling the key challenges in recycling of textile materials in different stages of their manufacturing process.

РАЗРАБОТКА ТЕХНОЛОГИИ РЕСТРУКТУРИРОВАННОГО МЯСНОГО ПРОДУКТА ИЗ БАРАНИНЫ

The article is devoted to the development of a technology for obtaining a restructured meat product from lamb. Increasing the production of meat products, expanding the range, increasing their biological value, as well as creating a new generation of products that meet the requirements of a healthy diet, are urgent tasks of the meat industry. Despite the development of the production of synthetic forms of food additives, the interest in the expanded use of non-traditional types of plant raw materials is constantly growing. In the meat processing industry, decoctions of medicinal herbs are used. They contain near-fatal substances (10-12%), essential oils, resinous substances (17%), anthocyanins (5-6%), flavonoids and other substances that have a preventive effect on diseases of the gastrointestinal tract. The development of scientific principles for the design of the composition and improvement of technologies for functional lamb meat products is an urgent problem of great scientific and practical importance. In this regard, experimental studies were conducted to develop a recipe for meat products for preventive use. Experimental studies were conducted in the laboratory of the Department of Food Technologies of the Don State Agrarian University. On the basis of the conducted research, a recipe and a technological scheme for the production of a restructured meat product from lamb were developed. The expediency of using phytocomponents in a meat product is justified. The dose of the introduction of phytocomponents into the product and the optimal method of applying multicomponent brine were established. On the basis of organoleptic and physico-chemical studies, a rational formulation of the product is proposed. The prototype No. 2 had a dense consistency and a pleasant taste. The average organoleptic evaluation of the developed product was 4.73 points, and the content of phytopreparations allows us to attribute it to functional products. The use of multi-component syringe brine in combination with mechanical processing of meat contributes to the formation of an elastic structure.

ANALYSIS OF ABSORPTIVE CAPACITY CONDITIONS BASED ON R&D PROJECTS

ABSTRACT Purpose: In this study, the notion of absorptive capacity (AC) and its configurations were adopted as a reference with the general goal of understanding the development stage of processes and routines of the acquisition, transformation and application of knowledge in the context of a public research company. Originality/value: One of the mobilizing factors in the agricultural sector in Brazil is the generation of new products and processes. In this case, the Brazilian Agricultural Research Agency (Embrapa) has played a role, especially in the absorption, internalization and generation of agricultural knowledge and innovations. In its processes, it involves its decentralized units and scientific and technological partners through research and development (R&D) processes. Identifying and systematizing the most effective forms and configurations in processes and routines associated with the dynamic of knowledge appropriation in a diverse and dynamic environment such as Embrapa constitutes a major challenge for scholars. However, recent studies have highlighted the growing diffusion of the debate on the AC construct. Design/methodology/approach: For this purpose, a case study was conducted involving Embrapa and three of its R&D projects. The study found evidence of intra-organizational and interorganizational alliances, as well as resulting important innovations. Findings: The principal contribution was identifying, in a public research company, the presence of routines and processes similar to those observed in the configurations of AC analyzed in the literature and the consolidation of routines and processes of knowledge absorption at the intra-organizational and interorganizational levels.

Analysis of the Energy Balance in the <i>Morus alba-Bombyx mori</i> System in Cuba’s Sericulture

The National Sericulture Project in Havana, started in 2011 to establish silkworm (Bombyx mori) rearing at a large scale in order to generate products to be used in the cosmetic, biomedical, biotechnological and pharmaceutical industries. The feeding of Bombyx mori L. exclusively depends on mulberry (Morus alba L.), so turning this system into a sustainable one for its development in the country requires an efficient use of the energy mainly based on the energy input-output relationships, on having mulberry cultivars of a high photosynthetic efficiency, on increasing agroecological practices and introducing other agricultural activities to diversify the intensive mulberry production system. The analysis of the energy balance used the software Energia 3.01, designed to estimate the energy of agroecosystems. The management of the area was characterized by identifying conventional agroecological practices developed on it. The results of estimating the energy efficiency indicate a mean efficiency for a specialized system depending on very few external outputs. These results were compared to 2019 the energy balance made in 2017. The introduction of new productive activities leading to increased energy efficiency and the generation of new products with a favorable impact on the environment and on the energy balance of the system, were proposed.

ИССЛЕДОВАНИЕ АДГЕЗИОННЫХ И ТЕПЛОЗАЩИТНЫХ СВОЙСТВ РЕЗИН НА ОСНОВЕ ЭТИЛЕН-ПРОПИЛЕН-ДИЕНОВЫХ С АРИМИДНЫМ НАПОЛНИТЕЛЕМ

Reinforced materials of the "fabric filler-vulcanized rubber" type may be successfully operated under the condition of the specified adhesive strength at the interface of the "substrate-polymer (rubber) "contact. The article presents theoretical infor-mation about ethylene propylene (EDM) and ethylene-propylene-diene (EPDM) synthetic rubbers, known internationally under the brand name EPDM-monomer, arimide fiber and laboratory research methods. The advantages of using EDM and EPDM in the manufacture of heat-protection coatings are; high heat resistance, low density, good compatibility with fillers (mineral and synthetic), compatibility with epoxy and phenol-formaldehyde resins, belong to coking materials. The article also provides the results of experiments and analysis of the data obtained, namely, the adhesive strength and thermal effect of rubbers based on EPDM with an arimide filler of a non-woven structure. The object of the research was modified heat-protective materials based on EPDM, and the subject of the research was selected rubber compounds based on EPDM and synthetic arimide fiber. To as-sess the physicochemical and thermophysical properties, a derivatographic analysis was performed, which includes TGA and DTA, two vulcanized rubber-woven samples from rubbers of grades 51-1615, 51-2110 together with arimide fiber. For the first time, results were obtained using ethylene-propylene-diene rubbers, including modification with a phenol-formaldehyde resin, which gives a higher erosion resistance when exposed to high-speed heat flow. Analysis of the results of experimental studies has shown that the use of arimide fiber can provide higher strength and thermophysical properties of heat-protective materials. In general, the results obtained may be of practical significance for the development of new-generation products.

On The Problem of Operation of Self-Propelled Drilling Rigs in the Harsh Winter Conditions of the Far North

In the North-East and Arctic regions of the Russian Federation, self-propelled drilling rigs of various modifications are in high demand for drilling of various purpose wells during exploration and engineering works. Due to the geographical inaccessibility of the production sites during the warm season, the bulk of drilling work is carried out in winter. The drilling fleet of exploration companies is becoming obsolete due to the lack of stable production of new generation drilling equipment by domestic plants, so now the process of purchasing imported equipment with higher technological capabilities, but not enough adapted to work in the harsh climatic conditions of the cryolithic zones of the northern and arctic regions, has begun. Besides, the enthusiasm for imported equipment, as we know, leads to constant dependence on foreign companies - suppliers of spare parts, technological means and materials and providing maintenance of drilling rigs.
