Opis:
The paper presents the main problems and their solutions in the reconstruction of treatment facilities in the Russian Federation. The results of research aimed the use of the stable system, which is based on nitrification activated sludge appliance, when the sludge contains bacteria-heterotrophic-nitrificators, are shown. The working process after the reconstruction was high effective (about 98% organic compounds removing, and about 99% ammonium nitrogen removing). Analysis of the treatment facilities after reconstruction proves theoretical assumptions about the system. These data confirm the stability of the developed technological schemes and give reasons to recommend it for further implementation of the reconstruction of treatment facilities

Opis:
The article describes the results of the eco-balance analysis of the disused lead-acid batteries recycling technology. The analysis will be made using the life cycle assessment (LCA) method. The analysis was developed using the SimaPro7.3.3. software. The life cycle assessment (LCA) was made using Ecological Scarcity and IMPACT2002 + methods. The results are shown as environmental points [Pt], which reflect the potential level of environmental burdens exerted by the analysed object. The results are presented in the environmental categories, which are grouped in the impact categories. For the Ecological Scarcity method, these are emission into air, water, soil, energy, and natural resources and deposited waste. For the IMPACT2002 + method: human health, climate changes, ecosystem quality and resources consumption. The boundaries of the system under investigation include the processes of mechanical battery scrap processing, desulfurization and crystallization processes (PI), the melting processes to obtain crude lead and refining processes (PII and PIII). As the functional unit, there was accepted 1 Mg of the processed battery scrap. Particular attention was paid to the airborne emission, which adversely affect human health and climate change. The technology for which the tests were conducted offers the possibility to recover other elements, for example, secondary lead, polypropylene and sulfuric acid as crystalline sodium sulphate.

Opis:
Double-haploidization (DH) is one of the favorable techniques to obtain 100% pure double haploid plants (DH’s) for generating the new F1 cultivars in a short time. The fecundity of this technique depends on the high quantity of haploids and also fertile DH’s. However, there are no comprehensive reports on the chromosome doubling and fertility (fruit and seed-set) of winter squash and pumpkin haploids, currently. Thus, to obtain high frequency and fertile DH’s, the efficiency of different anti-mitotic agents (colchicine, amiprophos methyl, trifluralin and oryzalin) was tested at various concentrations and exposure times for both in vitro and in vivo conditions. Haploid plantlets recovered from anther cultures of winter squash and pumpkin lines were used for DH program. The haploid plants were wholly immersed in aqueous solutions of antimitotic agents in vitro and apical parts of haploid plantlets were treated with anti-mitotic agents three times in vivo. Since some plants remained haploid, and the highest DH efficiency was obtained from multiple treatments of colchicine to shoot tips of haploid plants in the rate of 93.3%. In vivo multiple treatments of 1% colchicine for an hour was found to be the best doubling procedure for the recovery of high-frequency fertile DH’s in our winter squash and pumpkin breeding program.

Opis:
The causes of plane crashes, stemming from the subcritical growth of fatigue cracks, are examined. It is found that the crashes occurred mainly because of the negligence of the defects arising in the course of secondary metalworking processes. It is shown that it is possible to prevent such damage, i.e. voids, wedge cracks, grain boundary cracks, adiabatic shear bands and flow localization, through the use of processing maps indicating the ranges in which the above defects arise and the ranges in which safe deformation mechanisms, such as deformation in dynamic recrystallization conditions, superplasticity, globularization and dynamic recovery, occur. Thanks to the use of such maps the processes can be optimized by selecting proper deformation rates and forming temperatures.
Dokonano analizy przyczyn katastrof lotniczych wskutek podkrytycznego rozwoju pęknięć zmęczeniowych. Stwierdzono, że do katastrof tych dochodziło głównie z powodu nieuwzględniania uszkodzeń powstających podczas wtórnego kształtowania materiałów. Wykazano, że istnieje możliwość eliminowania takich uszkodzeń, to jest powstawania: pustek, pęknięć klinowych, pęknięć między krystalicznych oraz adiabatycznych pasm ścinania i lokalizacji odkształceń. Wymaga to jednak stosowania map procesów kształtowania, określających zakresy występowania w/w uszkodzeń oraz zakresy występowania bezpiecznych mechanizmów odkształceń, do jakich należy odkształcanie w warunkach rekrystalizacji dynamicznej, superplastyczności. globularyzacji i zdrowienia dynamicznego. Stosowanie takich map umożliwia optymalizację procesów poprzez dobór odpowiedniej prędkości odkształceń i temperatury kształtowania.

Opis:
The article outlines the cultural context of Russian women who contributed to the development of decadent poetry in the late 19th and early 20th centuries, most now forgotten or “occulted” (eclipsed, crowded out). Given the importance of gender theories and “feminine” discursive space in the Silver Age, this phenomenon must be examined; it is not just a typical example of women written out of literary history. The article suggests reasons why decadence may have appealed to women as well as why Russian women who adopted a specifically decadent position might not have been taken seriously. It ends by suggesting why more famous Russian poets (especially Axmatova and Cvetaeva, whose reputations have lasted and grown) achieved more lasting influence thanks to their occulted female predecessors.

Opis:
In this study, a mathematical formulation for static bending analysis of a beam on a non-homogenous foundation is presented. The proposed method offers an accurate procedure for analysis and design of a beam resting on a varying soil bed. The Winkler foundation model is used and presented using discontinuous functions to account for the sudden change in the soil stiffness coefficient. The solution of the governing differential equation is then obtained using the Galerkin method with the help of approximation functions that satisfy the boundary conditions. A systematic approach for setting the approximation functions for different support and soil conditions is suggested. The accuracy of the proposed method is verified through two numerical examples, and they showed an excellent agreement with the finite element method (FEM) and available literature results.

This study investigated arbuscular mycorrhizal fungi (AMF) inoculation and phosphorus fertilizer on growth, productivity and quality of onion grown under saline soil conditions. The experiment was conducted in the Experimental Farm of Desert Research Center, Ras Sudr, South Sinai Governorate, Egypt. Egyptian local onion cultivar ‘Giza 20’ was selected. Treatments were: two arbuscular mycorrhizal fungi (AMF) inoculation treatments [without inoculation (–AMF) and with mycorrhizal inoculation (+AMF)] and four phosphorus supplied treatments (0, 48, 96 and 144 kg P2O5 ha-1). Mycorrhizal inoculation and phosphorus addition affected the plant growth, bulb yield and quality. Morphological traits of plant (height, leaf number, fresh and dry weight), neck diameter, bulb characters (diameter and weight), total soluble sugars (TSS), protein, P content increased, while proline content decreased due to the inoculation of AMF and phosphorus application. Onion inoculated by AMF combined with 96 or 144 kg P2O5 ha-1 gave the highest productivity under saline conditions.

Opis:
Navigation is a complex interaction between human, organizational, environmental, and technological factors on the ship’s bridge. Today, ships bridges include a broad suite of equipment with both digital and analogue interfaces, covering a range of functions and purposes. Suboptimal usability in equipment and interface design as well as layout of the ships bridge has been reported by researchers for decades. This paper aims to contribute to our understanding of why there has been limited progression in usability in ship bridge design over the last decades, by investigating the stakeholders’ different perspectives of their influence, interest and responsibility for usability in ship bridge design. The study is based on interviews with seafarers, shipowners, equipment manufacturers, shipyard, insurance companies, classification societies and a flag state. Usability in navigational equipment and systems on a ship’s bridge is required by the International Maritime Organization (IMO) SOLAS Regulation V/15. We find that this goal-based requirement is challenging to follow up both in design, development, and survey work. To achieve usability in maritime equipment and bridge systems ideally requires the actively involvement of end-users throughout the design and development process. We find that the seafarers, the direct end-users, do not have a clear voice in the ship bridge and bridge equipment design and the associated purchasing processes. The other stakeholders appear to recognize the existing shortcomings, and some do show interest in improvements, but the responsibility for usability seem to be fragmented, and they see the potential solutions as being somebody else’s problem. We conclude by suggesting both long-term and a short-term way forward for improving usability in ship bridge design.

There is extensive literature addressing the subject of “emotional intelligence” (EI) and its importance to the profile of leaders and models of leadership. Despite what some have argued as the sine qua non of leadership, there are arguably few, if any, valid instruments available to predict demonstration of EI competencies. This paper focuses on EI and challenges to measurement as it relates to leadership development in maritime management —where EI competencies are deemed critical to effective performance. The authors review and evaluate current instruments that claim to measure EI, survey hiring practices in selected companies in the shipping industry, and make recommendations for further research.
