Funding sources used in construction logistics centres

In recent days the questions related to the use of public-private partnership (PPP) in the logistics activities are of a great importance. This article reveals the most common sources of funding that can be used in the construction of logistics centers, analyzes the types of support to the private sector in the implementation of PPP projects

Research of risks in the implementation of construction projects of the logistics centers on the basis of public-private partnership

In this paper the authors proposed to consider public-private partnership (PPP) as a methodological basis for the creation of the logistics center. The paper analyzes the characteristics of risks disclosing their nature, impact on the project, methods of influence on the risk and distribution between the partners in the implementation of construction projects of the logistics centers based on PPP

Теоретические аспекты и роль дебиторской задолженности в современной экономической системе

Дебиторская задолженность играет важную роль в экономике. Слишком высокая ее доля в общей структуре активов хозяйствующего субъекта снижает ликвидность и финансовую устойчивость организации и повышает риск ее финансовых потерь

Plant thionins: structure, biological functions and potential use in biotechnology

Antimicrobial peptides (AMPs) are important components of defense system in both plants and animals. They represent an ancient mechanism of innate immunity providing rapid first line of defense against pathogens. Plant AMPs are classified into several families: thionins, defensins, nonspecific lipid-transfer proteins, hevein- and knottin-type peptides, hairpinins and macrocyclic peptides (cyclotides). The review focuses on the thionin family. Thionins comprise a plant-specific AMP family that consists of short (~5 kDA) cysteine-rich peptides containing 6 or 8 cysteine residues with antimicrobial and toxic properties. Based on similarity in amino acid sequences and the arrangement of disulphide bonds, five structural classes of thionins are discriminated. The three-dimensional structures of a number of thionins were determined. The amphipathic thionin molecule resembles the Greek letter Г, in which the long arm is formed by two antiparallel α-helices, while the short one, by two parallel β-strands. The residues responsible for the antimicrobial activity of thionins were identified. Thionins are synthesized as precursor proteins consisting of a signal peptide, the mature peptide region and the C-terminal prodomain. Thionins protect plants from pathogenic bacteria and fungi acting directly on the membranes of microorganisms at micromolar concentrations, although their precise mode of action remains unclear. In addition to plant pathogens, thionins inhibit growth of a number of human pathogens and opportunistic microorganisms, such as Candida spp., Saccharomyces cerevisiae, Fusarium solani, Staphylococcus aureus and Escherichia coli. Thionins are toxic to different types of cells including mammalian cancer cell lines. Transgenic plants expressing thionin genes display enhanced resistance to pathogens. A wide range of biological activities makes thionins promising candidates for practical application in agriculture and medicine

Beer and teens

The results of an anonymous survey showed that today teenage beer consumption is a very topical issue. This article empirically proves that beer has a negative effect on various biological objects, and even more so on a fragile children's organism.Результаты анонимного анкетирования показали, что на сегодняшний день употребление пива подростками является очень актуальной проблемой. В данной статье опытным путем доказывается, что пиво негативно влияет на различные биологические объекты, а тем более на неокрепший детский организм
