Authors: Al-Msari A.A.R.A. , Rudenko A. A. 
Published: March 2024

Introduction. In recent days, the resources of a construction project (СP) are limited; therefore, the main tasks of managing the resource supply of construction production (RSСP) are optimal planning of resources and management of material and technical support. This includes managing the resources, supply, inventory management and distribution of resources by type of construction and installation work (CIW).Materials and methods. For a systematic analysis of the functioning of a construction project, organizational and technological subsystems are identified that have the greatest impact on the quality and reliability of construction systems. These include construction scheduling, resource support for construction and estimates that determine the cost characteristics of construction production.Scientific novelty. As a criterion for determining the effectiveness of the construction process, the article proposes to use the organizational and technological reliability (OTR) of complex development, taking into account resource supply. The article examines the factors influencing this criterion, as well as determines the indicators of factors and the interval values of the risk assessment of OTR. The values of the OTR indicator are obtained, which is the probability of completing the project on time, and the classification of factors affecting OTR is supplemented.Results. Contractors and developers provide construction facilities with all necessary resources according to the technological sequence of production of the CIW, established calendar plans and construction schedules. The organisation of complete supplies of resources through enterprises and divisions of production and technological equipment, as well as production and acquisition bases will provide for the redistribution of necessary resources to fulfill the production program between the construction sites of complex development.The novelty of the study lies in the modelling of the organizational and technological reliability of complex development, taking into account the risks of resource supply.Discussion and conclusion. To ensure successful resource provision, it is necessary to take into account the risks and take into account, within the framework of information programming, the organizational and technological reliability of the technological processes of the construction project, taking into account the specific conditions and factors of the implementation of the integrated development project.

Authors: Salikhov R. F. , Berdnikov I. E. 
Published: March 2024

Introduction. Over the years of cooperation between foreign manufacturers and domestic operating enterprises, a significant amount of construction equipment has been supplied. In this regard, there is a need to develop and improve existing standards governing the methodology for calculating the operating modes of construction machines. Often, the use of indicators given in regulatory documents shows a significant discrepancy in comparison with the actual indicators obtained characterizing the annual operating modes of machines. The article presents a method for calculating the annual duration of technical maintenance and repairs (TM and R) using the example of single-bucket hydraulic excavators of domestic (EOD) and foreign production (EOFP).Methods and materials. The method is based on the obtained patterns of changes in operating time between failures, the duration of maintenance and repair of analogues of EOD and EOFP.Results. As the studies have shown, over the course of operation, the annual duration of maintenance and repair in the EOD increases by 1.73 times, and 1.13 times in the EOFP; the duration of a single maintenance and repair in the OED is 2 times, and 1.4 times in the EOFP; the average time between failures in the EOD is 1.65 times less than in the EOFP at the studied intervals. The indicator of the duration of the EOD in TO and P for 1 operating hours, based on the dependencies obtained, shows an excess of 4.25 times, and according to the regulatory source MDS 12-8.2007, it is 6.03 times higher than that of its foreign counterpart.Discussion and conclusions. As a result of the application of the proposed method, the annual fund of time costs associated with maintaining and restoring the working technical condition can be predicted not only for domestic, but also for foreign single-bucket hydraulic excavators, the accuracy of planning the work performed increases compared with existing standards, this enables to take into account the unevenly distributed annual downtime depending on the planned working time, this will have a positive effect on the planning of the use of equipment. The data obtained can be used for the EOFP of the 5-th standard-sized group as normative

Published: March 2024

Introduction. The high importance of the urban passenger transport complex as a system determining the level of socio-economic development of the urban area is formulated. One of the systemic problems of the passenger transport complex of modern cities is the decentralization of planning and management processes, which determines the structural imbalance of key subsystems. The results of a literary review are presented, during which the works devoted to improving the efficiency of the transport process, the process of providing energy resources and the process of maintaining rolling stock in good condition are considered. The necessity of developing a methodology ensuring the coordination of the state and functioning of key subsystems of the transport complex is noted. The purpose of scientific work is defined, the list of solved tasks is defined.Materials and methods. The structural scheme of the urban passenger transport complex is given, a conceptual approach to solving the problem of coordinated optimization of its key subsystems is described. The following are defined: the target indicator, the objective function and its limitations that determine the optimization process being implemented. A brief description of methods for determining and mutual coordination of structural parameters of subsystems forming the material basis of the transport complex is given.Results. Theoretical provisions reflecting a conceptual approach to ensuring the efficiency of urban transport systems based on the coordinated development of subsystems, based on the magnitude of the proposed integrated efficiency indicator, are presented. Based on the data obtained from the results of analytical studies and field experiments, a calculation was made that made it possible to determine the structural parameters of the subsystems of the urban passenger transport system of one of the cities, ensuring the maximum value of the efficiency of transport activities provided by structural coordination of the subsystems that make up the material basis of the urban passenger transport system.Discussion. The solution of the tasks set is reflected, indicators reflecting the achievement of the research goal are indicated, confirmation of the hypothesis about the possibility of improving the efficiency of the urban passenger transport complex through the implementation of conditions ensuring the coordinated development and interaction of key subsystems is formulated.Conclusion. A generalizing conclusion about the solution of an important scientific, methodological and applied task – to increase the efficiency of the passenger transportation process along urban passenger transport routes based on ensuring the coordinated development of the subsystems that make up its material base is formulated.

O discurso feminista nas ruas de Córdoba: análises de pichações
Authors: Cruz Camilla 
Published: March 2024

Neste artigo, pretendo compreender como o discurso feminista de pichações se manifesta nas ruas da cidade argentina de Córdoba. Atualmente, os movimentos feministas permeiam a sociedade para lutar pela equidade de direitos entre os gêneros. Dessa forma, é importante atentar para as pichações, pois significam uma forma de luta na urbe, visto que o sujeito feminista produz sentidos ao expressar-se no espaço urbano onde transita. Por isso, busco refletir sobre os efeitos de sentido produzidos no discurso da cidade, lugar onde os sujeitos-feministas manifestam suas vozes anonimamente. Neste sentido, com base na Análise do Discurso francesa, analiso fotografias autorais de pichações de Córdoba que podem expressar uma ideologia feminista. O aporte teórico desta pesquisa se baseia nos estudos dos seguintes analistas de discurso: Pêcheux (1990, 1999, 2014) e Orlandi (2001, 2004, 2009). As pichações selecionadas para esta pesquisa ressoam discursos de luta feminista passageiros e anônimos, que se materializam na urbe. Por onde passamos, há discursos que podem desaparecer e/ou ser transcritos em momentos indeterminados, por sujeitos desconhecidos. Finalmente, é possível considerar que os discursos feministas cordobenses podem demonstrar a produção de efeitos de sentido no espaço urbano sobre o aborto, a violência de gênero e o combate ao machismo.

Polymorphism in cherry plum (<i>Prunus cerasifera</i>) and its significance for stone crop breeding
Authors: Eremin G. V. , Eremin V. G. 
Published: March 2024

A gene pool of cherry plum (Prunus cerasifera Ehrh.) numbering over 1000 accessions including wild forms and released cultivars of various origins has been gathered at the Krymsk Experiment Breeding Station, a branch of VIR. The study of the morphological diversity of cherry plum, or myrobalan plum, made it possible to clarify its position within the system of the genus Prunus L., and to propose an intraspecific system composed of three subspecies: Prunus cerasifera subsp. cerasifera – the typical cherry plum, P. cerasifera subsp. orientalis (M. Pop.) Erem. et Garcov. – the oriental cherry plum, and P. cerasifera subsp. macrocarpa Erem. et Garcov. – the large-fruited cherry plum with the following several varieties: Armenian (P. cerasifera subsp. macrocarpa var. nairica (Koval.) Erem. et Garkov.), Georgian (var. georgica (Erem.) Erem. et Garcov.), Iranian (subsp. macrocarpa var. iranica (Koval.) Erem. et Garcov), Pontic (subsp. macrocarpa var. pontica (Koval.) Erem. et Garcov.), Tauric (subsp. macrocarpa var. taurica (Kost.) Erem. et Garcov.), and the red-leaved cherry plum (Pissard plum) (subsp. macrocarpa var. pissardii (Carriere) Koehne).The most important role of interspecific hybridization involving the species P. cerasifera is in the origin of a number of Prunus L. species, including domestic plum P. domestica L., Fenzl’s almond P. fenzliana Fritsch, and black apricot P. dasycarpa Ehrh., has been established.The cherry plum gene pool had been found to contain donors of a number of traits of importance for breeding, which were used to create an assortment of Russian plum (Prunus × rossica Erem., hybrid myrobalan plum) cultivars and clonal rootstocks of stone fruit crops. Among them, the Russian plum ‘Globus’, ‘Kubanskaya Kometa’, ‘Gek’, ‘Kolonnovidnaya’, ‘Iyulskaya Roza’, and clonal rootstocks ‘Kuban 86’, ‘VVA 1’, ‘Evrika 99’, ‘Best’, ‘Zarevo’ have been regionally adapted and got a wide distribution.An outstanding general combining ability was demonstrated by cherry plum cvs. ‘Pionerka’, ‘Purpurovaya’, ‘Otlichtnitsa’, ‘Ashtarakskaya 2’ and ‘Tsiteli Drosha’, which were used in breeding a number of cherry plum cultivars at the Krymsk EBS, e.g. cherry plums ‘Neberdzhaevskaya Rannyaya’, ‘Kremen’, Russian plum ‘Kubanskaya Kometa’, ‘Iyulskaya Roza’, ‘Naydena’, ‘Gek’, ‘Podarok Sad-Gigantu’, etc.Most effective was the hybridization of Crimean, Armenian and Georgian cherry plum cultivars with the Chinese plum (Prunus salicina Lindl.) ‘Burbank’, ‘Gigant’, and ‘Skoroplodnaya’. As clonal rootstocks, the hybrids of myrobalan plum with peach (‘Kuban 86’ and ‘Fortuna’ rootstocks), with cherry plum ‘Sapa’ (‘Evrika 99’ and ‘Spiker’ rootstocks), as well as with low micro-cherry (rootstock ‘Best’) and Louiseania ulmifolia (Franch.) Pachom. (rootstock ‘Upriamets’) turned out to be very valuable.

Published: March 2024

One of the most important challenges in the production of gluten-free foods is the need to improve their nutritional quality. This work attempts to produce gluten-free noodles by substituting three different percentages of corn flour with hemp and to evaluate their technological and nutritional quality. This study used corn flour with 10.33 % protein and 1.57 % fiber and commercial hemp flour with 23.57 % protein and 28.75 % fiber. The pastas were made by extrusion by adding pregelatinized starch, ovalbumin and salt to obtain the control, then substitutions were made with 5 %, 10 % and 15 % hemp flour. The addition of hemp flour did not significantly affect the most important quality indicators, such as optimum cooking time and cooking residue, and even increased the firmness of the cooked pasta. Protein and fiber content increased significantly. It can be concluded that the addition of these percentages of hemp flour does not produce a deterioration of the technological quality of gluten-free pasta and allows for an increase in fiber and protein content, generating a significant improvement of nutritional quality.

Why Mature Galaxies Seem to Have Filled the Universe Shortly After the Big Bang — A New Cosmological Model, that Predicted the JWST Observations
Authors: Pletcher Arthur 
Published: March 2024

The Azimulthal Hyper-Projection (AHP) onto spacetime Model of Cosmology is just an extension of the familiar Atlas map of a globe in geography. The Atlas is an azimuthal projection of 3 spacial dimensions projected onto a 2 dimensional plane. The important feature of an Atlas is that the geometry expands asymptotic toward the horizon, and is therefore POSITIONALLY DEPENDENT, such that if North America is centrally positioned, then Siberia and Alaska are viewed as extremely remote. Thus if the Bering Strait were centrally positioned, then longitudinal meridians of North America would likewise be viewed as being remotely separated. AHP extends this concept to a hyper-projection of 5 dimensions onto spacetime. However as viewed in spacetime, geodesics appear to be expanding outward in 3 dimensional space away from the observer. Thus by extension, AHP is also POSITIONALLY DEPENDENT, such that the separations between remote galaxies appear (measures) to be much greater than they would appear from their mutual local group, and vice versa our local group of galaxies would appear to be mutually separated with extreme distances from a remote perspective. A proposed experiment (figure 14) is offered to prove that two separated objects, as measure from a remote distance \((\sim 40 AU)\) are greater than their respective distance, as measured locally.

Red-shifting is alternatively proposed as azimuthal angular projections of wavelengths \(\lambda\). Magnitude is alternatively proposed as a function of Lambert's cosine law of illumination, over expanding geodesics. From established \(z\) values, the Universal hypersphere is calculated (figure 9). A function of this projected hypersphere is shown to match the Universal expansion rate, as established from supernova cosmology survey points, and also satisfies the Cosmological Constant \(\Lambda\), without dark energy. Flattened galaxy rotation curves are simply and accurately explained as measured expanding geodesics and apparent increasing density, along the observer's line of sight (figure 11, equation 20). As well, this model provides a reasonable explanation of the James Web Space Telescope findings: of maturely developed galaxies at the time of the early universe. The justification of such a radically novel model is from recent observations from the first dataset, provided by NASA's James Webb Space Telescope (JWST) of six massive galaxies, at a time in the early universe, seem to defy conventional cosmological models, as they appear to be as mature and developed as our own local group. Such unexpected discoveries JUSTIFY A RADICALLY NOVEL MODEL OF COSMOLOGY. TO QUOTE JOEL LEJA, ASSISTANT PROFESSOR OF ASTRONOMY AND ASTROPHYSICS AT PENN STATE “IT TURNS OUT WE FOUND SOMETHING SO UNEXPECTED IT ACTUALLY CREATES PROBLEMS FOR SCIENCE. IT CALLS THE WHOLE PICTURE OF EARLY GALAXY FORMATION INTO QUESTION”.
Detailing the chemical composition of roasted soybeans and the effect for its use in the diet of dairy cows

Roasted soybeans are a complete source of indigestible protein in the rumen, have high sanitary and hygienic indicators, are devoid of non-nutritional substances of ordinary raw soybeans. The SoyPass and RaPass technology provides all the advantages of roasting soybeans and creates prerequisites for prolonged storage of beans for up to two years without prior drying. The introduction of full-fat flattened soybeans roasted by the Roast-A-Matic roaster into the diet of dairy cows leads to an increase in their milk productivity. Certified results of chemical research show that after frying, the percentage of crude protein significantly increased (by 2.92 points, P < 0.05) and the content of total digestible nutrients (by 8.1 %, P < 0.05), urease activity decreased to 0.06 ± 0.007 units of pH. The biological value of soy protein after frying corresponds to the indicators of the reference protein. Two groups of cows were involved in the study: № 1 – high-yielding cows with a daily milk yield of 30.69–35.96 L (n = 307) and № 2 – medium- and low-yielding cows with a yield of 19.05–28.88 L (n = 377). Group № 1 was given 300 g of roasted soybeans (111 g of protein) daily in their diet instead of 250 g of a high-protein supplement (200 g of protein); group No. 2 – gradually replaced 230 g of the supplement (184 g of protein) and 1500 g of 51 % meal (765 g of protein) with 1700 g of roasted soybeans (629 g of protein). In both groups, the 65-day observation period should be divided into 2 periods: 1) a 30-day period of intensive growth with a rapid increase in milk yield (up to +24.2–25.0 %); 2) the period of stabilization (from the 31st to the 65th day), characterized by some fluctuations in the % increase in milk, but in general by reliable maximum values (up to +25.0–36.7 %). The maximum daily volume in group № 1 reached 41.83 ± 1.04 and 41.83 ± 0.3 L (Р < 0.01) on the 32nd and 38th days, respectively. At the same time, the range of the indicators of the individual yield in the group ranged from 10.7 to 11.7 L. Similar indicators for group № 2 were: 32.56 ± 2.74 L (Р < 0.025) on the 58th day and 10.4–23.8 L. So, in the first 30 days of feeding full-fat fried soybeans, there is a rapid but unstable (with fluctuating peaks) increase in milk productivity of cows. During the 2nd month of soy consumption, the maximum milk yield is reached, when the increase in added milk is not rapid, but stable. Thus, it is advisable to introduce 1.5–2.0 kg/day of roasted soybeans (equivalent to 0.3–0.4 kg of fat/day) into the diet of dairy cows.
