Methyl 2-[(carbamoylamino)imino]-2-(3-{1-[(carbamoylamino)imino]-2-methoxy-2-oxoethyl}phenyl)acetate ethanol monosolvate monohydrate
In the title compound, C14H16N6O6·C2H6O·H2O, both substituents of the benzene ring are approximately planar with maximum deviations from the mean plane of 0.0561 (12) (an imine N atom) and 0.1419 (11) Å (a methoxy O atom). The substituents are tilted out of the plane of the benzene ring by 64.48 (4) and 70.08 (5)°, respectively. In the crystal, molecules form centrosymmetric dimers associated via pairs of N—H⋯O hydrogen bonds. The dimers are linked via the water and ethanol molecules, forming two-dimensional hydrogen-bond networks lying parallel to (100)

Specific Features of the Text in the Cognitive-Pragmatic Approach
This article differentiates the concepts of text and discourse, determines the fundamental differences and their relationship. Moreover, the article shows the role of pragmatics, a discipline that develops in close connection with cognitive science and evolutionary psychology and opens new ways to consider discourse analysis. In addition, we also discuss the relationship between pragmatics and discourse analysis, focusing on the links between the process of understanding utterances, which is in the realm of pragmatic theories, and the infl uence that is in the realm of discourse. The subject of our consideration is the text, the basic principles of its linguistic interpretation related to discourse, as well as the basic conceptual provisions of the modern theory of discourse
The sustainability implications of "product take-back clause" insupplier/retailer interface : case study: Swedish bread industry
Food waste consumes resources, has a negative effect on the environment and leads to monetary losses for the
supply chain participants. One of the ways to address food waste is to reconsider the supply chain´s linear
process and implement the reverse supply chain. Many researchers consider reverse supply chain to be
sustainable and value adding. Yet some studies mention that in supplier-retailer interface in the context of food
industries, reverse supply chains with take-back clause might be exposed to retailers’ market power abuse and
cause overproduction and waste. This study used the qualitative approach to explore implications of power
relations in retailer-supplier interface on take-back practice by looking at the case of Swedish bread suppliers.
All major bread suppliers that have take-back agreement along with retailer chains, representing all retailer
corporate ownership groups in Sweden have been interviewed. Using the theory of market power and reverse
supply chain sustainability, the study analyzed the implications of power-relations on the take-back practice and
explored sustainability concerns and/or fixtures it poses for the supply chain. The study findings do not fully
confirm with conclusions of previous research arguing that reverse supply logistics systems serve as additional
incentive for powerful retailers to over-order or lead to higher waste due to inability of suppliers to properly
dispose of waste. Yet other instances of retailer’s market power that have not been touched upon in previous
research were found within studied take-back agreement. The specific terms of agreement resulting from power
asymmetries were found to still cause over-ordering and other negative effects on the overall sustainability of
bread supply chains. The sustainability breaches identified in the study are mainly connected with lack of
retailer’s economic incentive to reduce the amount of unsold bread, which becomes the source of
overproduction, and leads to economic, environmental and social costs
The Role of Cultivated Plants of the Family Solanaceae in Agriculture
The role of algae (Solanaceae) in the agriculture of our republic is great. Potatoes and tomatoes from cultivated plants belonging to the family Solanaceae occupy large areas around the world and in our republic. The weight and quality of the product obtained from them is also high. The average yield of tomatoes in the country is 253 ts/h, the average yield of potatoes is 198 ts/h
{4-[(2,4-Dichlorobenzoyloxy)methyl]-1-phenyl-1H-1,2,3-triazol-5-yl}methyl 2,4-dichlorobenzoate
In the title molecule, C24H15Cl4N3O4, the triazole ring makes dihedral angles of 72.02 (12), 81.60 (12) and 73.82 (11)°, respectively, with the adjacent phenyl ring and the two dichlorobenzene rings. In the crystal, a weak C—H⋯N interaction, a short Cl⋯Cl contact [3.307 (2) Å] and a π–π stacking interaction [centroid–centroid distance = 3.568 (4) Å] are observed. An intramolecular C—H⋯O interaction is also present
Structural solutions of the supercharged engine in the output and input system
During the intake process, the working volume of the cylinder is filled with a fresh charge. As noted, a fresh charge consists of air in a diesel engine, and in engines with ignition from an electric spark (gasoline carburetor or gasoline with fuel injection, as well as gas) – from a mixture of air and vapors of light fuel or combustible gas
