The data of phytochemical studies are of great importance and contribute to supplementing the available information on the dynamics of the accumulation of primary and secondary metabolites in herbaceous plants on the territory of Dagestan.

Eksperimentalna istraživanja obradivosti održivog kompozita reciklažom otpadne plastike i poljoprivrednog otpada

Widespread applications of raw materials in building construction with population generation have steadily increased the demand for fresh raw materials and provoked environmental pollution. Development of sustainable building materials by recycling various solid waste could be a viable approach to reduce the problems arising from generating solid waste besides providing an alternative raw material for building construction. The present study demonstrates the development of polymeric composite materials as floor tile using different waste plastics, includes lowdensity polyethylene, high-density polyethylene, polyethylene terephthalate, and polypropylene as matrices with incorporation rice husk ash and sand as fillers. The workability of the developed materials was verified through experimental evaluations of physical, mechanical, and tribological properties. The minimum values of water absorption and abrasive wear were found to be 0.0397 % and 0.03267 (cm3 ) for the composites LDPE50PET20S30 and LD50S50, respectively. However, the composites HD50S50 resulted in an optimum mechanical strength with compressive strength and flexural strength of 46.2 and 6.24 (N/mm2 ), respectively. It was observed that the workability of the composites improves with the incorporation of sand particles. The scope of the present study relies on the development of methods and techniques for developing sustainable building materials through recycling of solid waste along with its characterization which provides an easy reference for solid waste processing towards sustainability.

The Use of Ultrasound in the Extraction of Biologically Active Compounds from Plant Raw Materials, Used or promising for Use in Medicine (Review)

Introduction.This review examines the current state of technology for ultrasonic isolation of biologically active components from medicinal vegetal raw materials. The main emphasis is placed on "green" technologies that intensify the processes of isolation of components such as flavonoids.Text.Modern technologies imply the use of combined methods, including, in addition to ultrasound, significant grinding of raw materials before the extraction process, the use of supercritical solvents (liquefied gases) under excessive pressure. The effect of ultrasound power and temperature on the output of the extracted components was also considered.Conclusion.1. To increase the yield of biologically active compounds from plant raw materials among various physical methods of extraction intensification, the use of ultrasound dominates. 2. Ultrasonic extraction can be divided into several main types: extraction in an ultrasonic bath, the use of submersible ultrasonic emitters, as well as the combination of ultrasonic extraction with additional types of influence. 3. In the literature, examples of the use of ultrasonic extraction for the isolation of phenolic compounds are most fully presented, it being noted that the parameters need to be selected individually for each individual plant. 4. The power of ultrasound and the nature of the extractant can affect the course of oxidative processes in the extract, and such phenomena are characteristic not only for too high capacities, but also for low ones. 5. Ultrasound can significantly increase the yield of biologically active compounds even in aqueous extraction of fresh raw materials. 6. The spectrum of extractants selection for ultrasonic extraction of plant raw materials is quite large. Both organic solvents (ethanol, methanol, ethyl acetate, acetone) and water can be used, as well as mixtures of various extractants.

The study and scientifical substantiation of critical control points in the life cycle of immunostimulating products such as pastila and marmalade

Based on the study results, this paper reports a technology to produce natural fruit and berry pastila and marmalade of improved nutritional and biological value with a long shelf life. Critical control points of product safety have been identified and scientifically substantiated. The technological process to prepare pastila and marmalade involves exposing the raw materials to high and low temperatures while maintaining certain indicators of the content of dry substances. The identification feature of marmalade products is the content of a certain type of fruit raw materials, which poses risks throughout the life cycle of product manufacturing despite the fact that the preparation and storage of the raw materials implies the temperature range from 0 °C to minus 15 °C. Problematic issues of mold occurrence have been considered. It was established that the moisture content in the product above 15 % leads to an increase in the content of mold fungi and significantly reduces its shelf life. This paper gives the results of a study to identify the preservation of vitamin C in products prepared from fresh berries and from berries subjected to freezing. It was revealed that in the process of storing the raw materials at a temperature of minus 15 °C, the amount of vitamin C in the resulting product decreased by 11.3 % compared to the product prepared from fresh raw materials. The maximum limit of the high preparation temperatures of 108 °C did not significantly affect the loss of vitamin C. Studies were conducted to determine the sugar content in products whereby a high fructose content was identified. Critical control points at all stages of production were determined, which has made it possible to choose the optimal technological modes and parameters for the safety and quality of the product

Comparative pharmakognostical study of roots of Rosa Majalis Herrm. and Rosa Canina L.

The aim is to conduct a comparative pharmacognostical study of the series of roots of Rosa (R.) majalis Herrm. and Rosa (R.) canina L. with the establishment of diagnostic features of morphological and anatomical structure and boundary limits of numerical indicators of raw materials.
 Materials and methods. The fresh and dry raw materials were used to study the macroscopic microscopic features by microscope Delta optical BioLight 300 (Poland). Determination of total polyphenols was performed by spectrophotometry (on a spectrophotometer Optizen POP (Korea)) and HPLC (chromatograph an Agilent 1200 3 D LC System Technologies (USA)).
 Results. The morphological (nature of the surface (periderm) and fracture) and anatomical (color of cell walls and their cavities; location of the sclerenchyma; the presence of a crystalline coating of the sclerenchyma at the root of R. canina; of various elements of the remains of the tetraarchic conducting bundle in the center of the root) diagnostical features of roots of R. majalis and R. Canina were established.
 Comparing the numerical values of loss on drying (not more than 10 %), total ash (not more than 5 %), extractable matter (not less than 9 %) and the quantitative content of total polyphenols (not less than 4 %) it was determined that both types of raw materials according to these indicators are almost indistinguishable.
 Conclusions. Loss on drying, total ash, extractable matter and content of total polyphenols of the root of R. majalis and R. canina do not have significant differences, that is why the root of both plant species can be used as medicinal plant raw materials such as “Rose root”. The obtained data will be used in further research when creating methods of quality control of plant raw materials and phytomedicines

Assessment of microstructural changes in processed products from green peas

A demand for canned vegetables and fruit depend, first of all, on their consumer characteristics. These products should correspond to high requirements regarding their nutritional and biological value, as well as sensory properties. The aim of the work was to study the microstructural changes in the cells of green peas in the products of their processing. Fresh, frozen and canned peas made from fresh and rehydrated raw materials were used as objects of the research. Components such as chlorophyll and starch were characterized in the cells of the hypodermis and parenchyma, respectively, using light microscopy. It was found that plastids with chlorophyll stained in the bright green color were present only in cells of the hypodermis of frozen peas. Moreover, the same color of the pigment was also recorded in the samples of fresh peas. Appearance of brown hues in these cells was observed in the canned product from fresh peas, which was associated with transformation of chlorophylls into pheophytins and pyrophephytins. The hypodermis in the samples of canned peas from rehydrated raw materials was represented by almost colorless cells. When analyzing the preparations of the parenchymal cells of the indicated processed products stained with iodine, it was shown that starch grains in the samples of frozen and canned green peas from fresh raw materials maintained their concentric shape, while swelling of starch grains was observed in the stained preparations of the parenchyma of canned peas from rehydrated raw materials. The comparative microstructural analysis of processed products from green peas showed that maximum quality had the frozen product from fresh raw materials as the studied indicators (chlorophyll and starch grains) showed.

Recycling lead and transparent conductors from perovskite solar modules

Perovskite photovoltaics are gaining increasing common ground to partner with or compete with silicon photovoltaics to reduce cost of solar energy. However, a cost-effective waste management for toxic lead (Pb), which might determine the fate of this technology, has not been developed yet. Here, we report an end-of-life material management for perovskite solar modules to recycle toxic lead and valuable transparent conductors to protect the environment and create dramatic economic benefits from recycled materials. Lead is separated from decommissioned modules by weakly acidic cation exchange resin, which could be released as soluble Pb(NO3)2 followed by precipitation as PbI2 for reuse, with a recycling efficiency of 99.2%. Thermal delamination disassembles the encapsulated modules with intact transparent conductors and cover glasses. The refabricated devices based on recycled lead iodide and recycled transparent conductors show comparable performance as devices based on fresh raw materials. Cost analysis shows this recycling technology is economically attractive.

The impact of government intervention in competitive electronic closed-loop supply chain to support internal industry

Due to the development of various industries, including electronic products industries, waste management of these products in order to reduce serious damages into the environment has been considered by human societies. On the other hand, due to the fact that a high percentage of the waste of these products have capability to use for production of new products, the management of these chains is more important to reduce production costs and consequently reduction the damage on the environment. There are competitive chains in which a variety of internal products are produced by a chain that competes with products produced by another chain abroad. In the proposed mathematical model, in addition to considering the waste management of these types of products, the government tries to intervene in a way that supports internal chain. Therefore, the first purpose of this study is to answer how waste management in the competitive chain (especially electronic products) and the second purpose is to answer how the government intervenes in this type of competitive chain to support domestic industry. These two cases will be examined by presenting a mathematical model. Due to the competitive demand function for both supply chains, the importance of pricing and quality determination is particularly evident. Optimal decision variables that impact on the demand functions are concluded by Stackelberg game using manufacturers leadership without and under government intervention. Numerical examples indicate reduction on using fresh raw materials for internal manufacturer and subsequently, reduction purchasing cost of fresh raw materials by government intervention. This leads to a reduction in production costs for the internal manufacturer, which in a way has led to a boom in the internal industry. Furthermore, government intervention leads to reduce in price of products for customers. Finally, in order to extract some management concepts, several sensitivity analyzes are performed on the main parameters.

Life cycle assessment of lithium-ion batteries and vanadium redox flow batteries-based renewable energy storage systems

Renewable energy has become an important alternative to fossil energy, as it is associated with lower greenhouse gas emissions. However, the intermittent characteristic of renewables urges for energy storage systems, which play an important role in matching the supply and demand of renewable-based electricity. The life cycle of these storage systems results in environmental burdens, which are investigated in this study, focusing on lithium-ion and vanadium flow batteries for renewable energy (solar and wind) storage for grid applications. The impacts are assessed through a life cycle assessment covering the batteries supply phase, their use and end-of-life, with experimental data from test set-ups. The battery composition is investigated in detail as a factor for the final impacts, by comparing two types of cathodes for the lithium-ion battery and the use of recycled electrolyte for the vanadium flow battery. Results indicate that the vanadium-based storage system results in overall lower impacts when manufactured with 100% fresh raw materials, but the impacts are significantly lowered if 50% recycled electrolyte is used, with up to 45.2% lower acidification and 11.1% lower global warming potential. The new lithium-ion battery cathode chemistry results in overall higher impacts, with 41.7% more particulate matter and 52.2% more acidification.

Devising nanotechnology for vegetable cryofrozen enrichers with biocomponents and the natural protein healthy snacks containing them

This paper reports the development of nanotechnology for processing vegetables (spicy and carotene-containing ones) into frozen cryoadditives – enrichers with biologically active substances (BAS), as well as natural protein health snacks containing them. An innovative method proposed for obtaining vegetable nano additives involves the use of deep processing of raw materials. The method is based on a complex effect exerted on raw materials by cryo-processing and cryomechanodestruction, making it possible not only to preserve the BAS of fresh vegetables but also to transform them into a nanostructured form in order to fully reveal the biological potential of the raw materials. The resulting nano additives made from vegetables have no analogs. The BAS mass fraction in the produced frozen cryoadditives is 3.0...3.2 times larger than that in the starting fresh raw materials. Vegetable-based cryoadditives that are used in the manufacture of snacks are not only the BAS carriers but also perform the functions of structure-forming agents, gel-forming agents, colorants, thereby making it possible to produce high-quality health products and eliminate the need for food additives. Applying the vegetable-based frozen cryoadditives enrichers with biocomponents has made it possible to devise a new generation of natural protein snacks for healthy eating. The protein base used included nano additives made from legumes (peas) and soft salt cheese, which are distinguished by a high content of complete protein and are easily digestible. The new protein-vegetable snacks differ from conventional ones in the high content of β-carotene, phenolic compounds, tannins; 100 g of the product may satisfy about 30 % of the daily protein needs. The devised snacks are a new type of natural wellness products that are made without the use of artificial food additives and are recommended for industrial production.

Analyzing a closed-loop sustainable supply chain with duopolistic retailers under different game structures

This article investigates a closed-loop supply chain consisting of a manufacturer, two suppliers and two competitive retailers. One retailer sells manufactured products whereas the other retailer sells remanufactured products and takes up corporate social responsibility (CSR). One supplier supplies used products or cores for remanufacturing while the other supplier supplies fresh raw materials for manufacturing new product. The manufacturer sells both new and remanufactured products with different wholesale prices. The paper analyzes the two competitive retailer's different game strategies when the manufacturer acts as the Stackelberg leader. It is shown that remanufacturing is a good policy to adopt for the whole supply chain, not only for economical benefits but also for environmental sustainability. Optimal decisions of the proposed closed-loop supply chain and its members are also supported by a numerical example. Finally, sensitivity analysis is carried out with respect to key model-parameters.

Effect of organic acids on the formation of biogenic amines in fermented anchovy sauce comprising raw anchovy materials with different levels of freshness.

We investigated the effect of different levels of organic acids on the formation of biogenic amines in anchovy fish sauce. Fish sauce samples were prepared with fresh anchovies used immediately after being caught (F), and anchovies left at ambient temperature for 4h (4h), 18h (18h), or 24h (24h). Anchovies from each of the four groups were mixed with salt at a 4:1 ratio and then fermented at ambient temperature for varying periods of time. The F and 4h anchovies contained higher levels of acetic acid, succinic acid, and lactic acid, and the levels increased during the fermentation process. The histamine content of the fish sauce samples prepared using F anchovies ranged from 44.0 to 9.2mg/kg at 1 and 24months of fermentation. The histamine content of fish sauce samples prepared using 4h, 18h, and 24h anchovies was 111.5-37.0mg/kg (4h), 780.1-560.3mg/kg (18h), and 880.6-675.7mg/kg (24h). Our findings indicated that the histamine and other biogenic amine levels were closely associated with the degree of freshness of the raw anchovy material. These findings indicate that lower pH levels resulting from organic acids generated by the fresh raw material can effectively inhibit histamine formation.

Experimental investigation on bending strength of compacted plastic-concrete

Conventional methods for recycling demolition concrete and plastic waste do not allow recycling of 100% demolished concrete or large volumes of plastic waste. Furthermore, fresh raw materials for concrete manufacturing are still required, while it is projected that they will soon be in short supply due to ever growing consumption. This study focuses on producing a stabilized construction material with better mechanical strength than traditional concrete. A novel method for recycling demolished concrete and plastic waste by compacting concrete and plastic powders under various pressures and temperatures is proposed. The effects of forming conditions on the bending strength of the compacted plastic–concrete (CPC) are analyzed. Furthermore, the water absorption ability and micro-structure of the CPC are also determined. The experimental results confirm the feasibility of CPC and show promising aspects of CPC related to recycling both types of waste in concrete applications, achieving a closed loop for concrete recycling and a high-volume plastic recycling ratio. SEM results showed that the hot-pressing method ensures a good fusion between concrete and plastic particles. Almost all the specimens formed under different conditions possessed a superior bending strength than traditional concrete, and its strength remains stable with up to 75% plastic composition in the specimen. Therefore, the proposed method reveals the feasibility of large-scale plastics recycling in construction, and makes the CPC competitive with other construction materials.

Effect of pre-treatment and drying methods on the content of minerals, B-group vitamins and tocopherols in kale (Brassica oleracea L. var. acephala) leaves

Dried vegetables are widely used in food production. Kale leaves, due to their high health-promoting properties, can be a valuable raw material for drying. The aim of the study was to evaluate the effect of blanching, drying methods (air-drying, freeze-drying), the time and temperature of storage on the content of ash, minerals, vitamins B1, B2, and tocopherols in dried kale products. The dried products were evaluated directly after processing and after 12 months of storage at ambient temperature, 18–20 °C and cold temperature, 8–10 °C. In 100 g dry matter from fresh raw material the dominant minerals were potassium (2613 mg), calcium (1346 mg), phosphorus (432 mg), magnesium (129 mg). Kale leaves had 0.828 mg vitamin B1, 1.533 mg vitamin B2 and 16.55 mg total tocopherols per 100 g of dry matter. Blanching, applied prior to drying, significantly reduced the levels of minerals (3–38%) and vitamins (8–45%), except for calcium, zinc and manganese. This pre-treatment had, however, a beneficial effect, especially on vitamin retention during the storage of dried products. After 12 month storage, the losses of vitamin B1, B2 and total tocopherols in dried, previously blanched, raw materials ranged from 3 to 10%, 1 to 4%, and 1 to 16%, respectively, depending on the type of sample. In the dried products obtained from unblanched raw material, the losses were larger and amounted to 10–17%, 8–16% and 4–17%, respectively. Throughout drying and storage, the minerals examined were fairly stable. Dried kale is generally a good source of minerals and vitamins. However, blanching before drying is recommended. In addition, freeze-drying and storage in cold temperature allows for higher vitamin preservation in dried kale.

Coordination of a sustainable reverse supply chain with revenue sharing contract

<p style='text-indent:20px;'>In this article, a three-echelon closed-loop supply chain is considered under sustainability consideration through remanufacturing of waste materials. Depending upon quality, the collector collects the used products and forwards to the manufacturer for remanufacturing. The collector offers a reward or incentive to consumers to influence them to return the used items. The shortfall amount of collected used items, if any, is meet up by the supplier by supplying fresh raw materials. In three separate cases viz centralized, decentralized and revenue-sharing contract, optimal incentives for end-customers and optimal profits of supply chain members are determined. The revenue-sharing contract is implemented in two different settings - one including the supplier and the other one excluding the supplier. The win-win outcome for the supply chain members is investigated and a specific range of the sharing parameter for win-win outcome is obtained. Optimal results are supported by numerical analysis, and sensitivity of the optimal results with respect to key parameters is analyzed.</p>

Use of rizostar in the production of sorghum silages

This study aimed to evaluate the development of culture, mass production, and the silage nutritional value of sorghum under three nutrients fonts. The experiment was conducted as a block randomized design, with three treatments and six replications. The treatments consisted of fonts fertilizations in showing: Monoammonium Phosphate, with 90.0 kg ha-1, and Rizostar with 37.5 kg ha-1 and 45.0 kg ha-1 doses. The productive parameters of the plants were evaluated at 30 days and at the time of harvesting the plants for silage, in addition to the nutritional value of the silages. The materials presented expressive productions, with averages of 43846; 43346; 44002; and 35674 kg ha-1 of green matter. The Maxisilo sorghum hybrid presented the highest levels of acid detergent fiber (ADF), with a mean of 471.42 g kg-1 dry matter (DM). Crude protein (CP) contents in each hybrid remained constant over time, presenting mean values of 74.37; 65.26; 54.44; 78.43 g kg-1. The mean total digestible nutrients values found in the Dominator sorghum hybrid were 657.34 g kg-1, being higher than the others. After long storage periods, the nutritional parameters of the materials remained stable in their CP, DM, NDF, and ADF values. The aerobic exposure nutritionally deteriorated silages. Fertilization with Rizostar 45, does not influence the final level of plants, fresh raw materials, and dry raw materials, besides significantly increasing the use of samples.

Use of Spent Mushroom Substrate in New Mushroom Crops to Promote the Transition towards A Circular Economy

The use of spent mushroom substrate (SMS) in new cultivation cycles has already been reported due to its economic and environmental viability. When considering the application of the circular economy concept in the production of edible mushrooms, the re-use of the SMS within the same process is highly attractive, because it allows a better use of the biomass and the energy involved in the process and, therefore, tends to improve energy efficiency and resource conservation. However, this alternative generates important challenges, which derive from maintaining the quality standards of the mushrooms produced and, at the same time, not incurring excessive costs that are detrimental to the process itself. In our opinion, the main difficulty of the process in achieving success is regarding the biological and agronomic parameters that involve the production of the mushroom. It is useless to apply SMS in new cycles if the mushroom harvest is impaired and farms become non-viable. However, numerous examples are reported here where SMS was recycled into new substrates for either the same or different mushroom species without negatively affecting yield compared with using substrates prepared from 100% fresh raw materials. Thus, we suggest that each farm has its own specific technological study, since a small variation in the raw material of the compost, and mushroom cultivation practices and casing layer used, can influence the entire viability of the mushroom circular economy.
