The article studies the conditions favorable for the formation of opportunistic behavior of subjects of the credence goods market. The absence of a number of rules, which should govern social and legal relations in the sphere under the study, along with imperfection and inefficiency of the existing rules allowed to identify a group of institutional conditions for developing opportunism. The limitations of competition, the variability of the economic environment, wide range of differentiated products and the unevenness of their distribution, the dependence on external raw material sources form the group of market conditions. Impulsivity, suspiciousness and difficult predictability of the behavior of ordinary consumers, but also inherent in modern society the spiritual and moral decline form the group of socio-psychological conditions for opportunistic behavior. The article discusses in detail each of the groups, the examples of the Russian practice are given.

The problem of how to remediate protein deficiency in the human diet can be solved by using new raw material sources or by consuming vegetable proteins, in particular, sunflower protein, more efficiently. Sunflower is high in biologically complete proteins with a wide range of functional properties. This makes it practical to use sunflower protein as a component of forcemeats for frozen semi- processed minced meat products. As this task is highly topical and promising, it has determined the direction of further research. The purpose of the research is to establish how sunflower protein affects the qualitative characteristics of forcemeat for frozen semi-processed minced meat products, and to specify the rational norms of using it in their composition. It has been studied how sunflower protein effects on the moisture-holding capacity of forcemeat. The results have shown a sharp increase in this parameter after introducing sunflower protein. It has been established that sunflower protein affects the processes of freezing and defrosting in forcemeat systems. However, it has no pronounced cryoprotective properties independent of  its concentration in a system, and the loss in weight during freezing the samples is but insignificant. Studying the effect of sunflower protein powder on the sensory, functional, and technological properties of forcemeat reveals positive dynamics and direct relationship between these characteristics and the concentration of sunflower protein. The losses in the weight of the semi-processed products during heat treatment have been analysed. The   data   obtained  have  shown  that   this   parameter   decreases   by 1.9 times when sunflower protein is used. Sensory evaluation of the samples has allowed establishing that the rational norm for sunflower protein as a forcemeat component is up to 10%. Thus, the research conducted prove that it is practical to use sunflower proteins as components of forcemeats for frozen semi-processed minced meat products. This will make the products more nutritious, allow controlling their amino acid composition, curtail the expenditure of raw meat, help control the rheological parameters, and expand the range of products.

Abstract Biochar is currently applied in many low-impact development measures, such as biofilters and filter strips. However, its application in permeable pavement is limited. Due to the wide range of raw material sources, biochar may also contain nutrients and heavy metals. Whether its leachate will cause contamination during application remains unknown. Based on the static leachate contamination test, this study first evaluated the leachate contamination risks of three types of biochar and porous asphalt mixture (PA) with three biochar fillers. Through the pavement infiltration test, the purification performance of PA with biochar fillers and filter layers was further analysed. The results show that biochar contains nitrogen and phosphorus, and the leaching contamination of coconut shell is the most obvious; when the biochar is applied as a filler in PA, the leaching contamination decreases, while the pollutant purification performance is not obvious; when 3−5 mm rice straw biochar is used as a filter layer, the removal rate of total suspended solids can be 100%, but it is accompanied by more serious nitrogen and phosphorus leaching, and the greater the thickness, the more serious the degree of leaching. Deionized water cleaning can remove the phosphates contained in biochar, but have little effect on nitrogen. Therefore, before the application of biochar, cleaning measures should be taken to minimize its leaching contamination.

Any change of the raw material sources for glazes, economically, ecologically motivated, and also from the glaze quality point of view, is conditioned by the molecular formula rationalization and by the variation limits of the molecular formula, respectively. The proper glaze compositions are placed within their limit variation intervals with optimized processing and utilization properties. For this purpose, the rationalization criteria and procedures of molecular formulas are summarized in the present paper, as well as the results referring to their rationalization obtained in the authors� previous work. Thus, one starts from a base of raw materials that are selected, usable and also accessible for the design and producing of the glazes. On these bases the groundwork and the design equation for the glaze recipes are developed, exemplified for a single glaze. For an easy access to results, computer programs are used for an easy access to results.

Phenol–formaldehyde (PF) resin continues to dominate the resin industry more than 100 years after its first synthesis. Its versatile properties such as thermal stability, chemical resistance, fire resistance, and dimensional stability make it a suitable material for a wide range of applications. PF resins have been used in the wood industry as adhesives, in paints and coatings, and in the aerospace, construction, and building industries as composites and foams. Currently, petroleum is the key source of raw materials used in manufacturing PF resin. However, increasing environmental pollution and fossil fuel depletion have driven industries to seek sustainable alternatives to petroleum based raw materials. Over the past decade, researchers have replaced phenol and formaldehyde with sustainable materials such as lignin, tannin, cardanol, hydroxymethylfurfural, and glyoxal to produce bio-based PF resin. Several synthesis modifications are currently under investigation towards improving the properties of bio-based phenolic resin. This review discusses recent developments in the synthesis of PF resins, particularly those created from sustainable raw material substitutes, and modifications applied to the synthetic route in order to improve the mechanical properties.

Abstract The objective of the present study is to examine the fine structure of vegetative cells of Laminaria digitata using both chemical fixation and cryofixation. Laminaria digitata was chosen due to its importance as a model organism in a wide range of biological studies, as a keystone species on rocky shores of the North Atlantic, its use of iodide as a unique inorganic antioxidant, and its significance as a raw material for the production of alginate. Details of the fine structural features of vegetative cells are described, with particular emphasis on the differences between the two methods used, i.e. conventional chemical fixation and freeze-fixation. The general structure of the cells was similar to that already described, with minor differences between the different cell types. An intense activity of the Golgi system was found associated with the thick external cell wall, with large dictyosomes from which numerous vesicles and cisternae are released. An interesting type of cisternae was found in the cryofixed material, which was not visible with the chemical fixation. These are elongated structures, in sections appearing tubule-like, close to the external cell wall or to young internal walls. An increased number of these structures was observed near the plasmodesmata of the pit fields. They are similar to the “flat cisternae” found associated with the forming cytokinetic diaphragm of brown algae. Their possible role is discussed. The new findings of this work underline the importance of such combined studies which reveal new data not known until now using the old conventional methods. The main conclusion of the present study is that cryofixation is the method of choice for studying Laminaria cytology by transmission electron microscopy.
