La importancia del "buen casar". Un acercamiento a la política matrimonial de las camaristas de Palacio en tiempos de Carlos III
Authors: Peña Ramos Jon 
Published: July 2023

El presente trabajo pretende dar a conocer la política matrimonial de las camaristas de Palacio que casaron durante el reinado de Carlos III (1759-1788). Estas jóvenes solteras de condición noble formaban parte del círculo femenino palatino y sus puestos cortesanos les granjearon multitud de posibilidades y oportunidades. Entre ellas la de desposar a un contrayente de renombre. Partiendo de este conjunto pretendemos analizar, por un lado, el perfil de las camaristas que tomaron estado y el de sus futuros maridos. El estudio prosopográfico de esta cuestión, así como la utilización de casos particulares de la segunda mitad del siglo XVIII, posibilitará atender a otras cuestiones tales como sus contextos familiares o las redes clientelares en las que se insertaban. Todo ello será posible a través del análisis y valoración de los fondos documentales conservados en los archivos nacionales, y particularmente en el Archivo General de Palacio.
El "efecto Lepanto"
Authors: García Hernán David 
Published: July 2023

Este trabajo pretende mostrar a través de algunos aspectos significativos que la batalla de Lepanto, lejos de considerarse un enfrentamiento inútil y sin ninguna trascendencia, como ha venido diciendo la historiografía tradicional, tuvo importantes implicaciones. La nueva historia cultural y el riquísimo panorama de representaciones culturales sobre el hecho que se están estudiando en los últimos años, permite acercarnos a nuevas perspectivas bastante esclarecedoras; así como otros aspectos que nos introducen en el verdadero contexto político global del momento, y también importantes dimensiones prácticas, como el desarrollo de la logística. Ello nos permite acercarnos, ayudados por algunos documentos originales no conocidos hasta ahora, y más allá de una simple mirada -ventajista- sobre los hechos posteriores, al verdadero sentido de la victoria cristiana.

MISSILE MOVEMENT CONTROL SYSTEM STABILITY RESERVE
Authors: Avdieiev V.V. , Aleksandrov A.E. 
Published: July 2023

The requirement to ensure the necessary stability factor of the rocket's rotational motion is one of the most important. It is known, the parameters of the rocket as a control object during the flight depend on the point of the trajectory and fuel consumption, that is, the stabilization system is time-varying. In the available sources, due attention is not paid to the development of a mathematical apparatus for determining the quantitative assessment of its stability factor.
The purpose of the work is to substantiate the possibility of establishing a section of the trajectory on which the non-stationary system is matched by an equivalent system with
constant parameters. This reduces the level of complexity of algorithms for the study of dynamic characteristics the margin of stability.
The mathematical model of the stabilization system is adopted in the form of a linear differential equation with time-varying parameters of the control object without taking into account the inertia of the executive device and other disturbing factors. The effect of the deviation of the parameters from their average values ​​for a certain part of the trajectory is considered as a disturbance that makes it possible to move from an approximate stationary model to a non-stationary one without increasing its order.
Using the example of a time-varying system for stabilizing the rocket rotational motion in the yawing plane, the possibility of using the Laplace transformation to determine the indicators of the stability factor by amplitude and the stability factor by phase is shown.
The obtained results can be used in the design of a stabilization system with time-varying parameters.
The next stage of the research is an assessment of the level of complexity of the calculation algorithm when increasing the order of the mathematical model of the control object.
INFLUENCE OF OPERATIONAL LOADS ON BALLASTING PARAMETERS OF UNDERWATER CROSSINGS OF TRUNK OIL AND GAS PIPELINES
Authors: Azmetov Kh. A. , Pavlova Z. Kh. , Krygin V. V. 
Published: July 2023

The trunk oil and gas pipelines are under operational loads affecting the strength and reliability of the structure. The most significant effect of loads is manifested at pipeline crossings across rivers. The stability of underwater pipeline design position and thus its reliability is achieved by ballasting with the required intensity. The current regulatory document SP 36.13330.2012 provides for the required intensity determination, taking into account the water buoyancy force and pipeline crossing along the longitudinal profile of the transition. At the same time, it should be noted that ensuring pipeline bending along the longitudinal profile of the crossing with the use of ballasting of the required intensity also depends on the internal forces acting in the pipeline wall during operation. However, this document does not take into account operational loads when determining the required ballasting intensity. In addition, ballasting with the ensuring pipeline bending along the longitudinal profile of the crossing leads to the occurrence of bending stresses, in some cases quite high, which affect the level of total stresses, strength and reliability of the structure. In many cases, water occupies only part of the concave section of the pipeline at crossings. Taking into account the above conditions and features, studies of the ballasting of underwater crossings of trunk oil and gas pipelines were carried out.
The aim of the work is to obtain analytical dependences of the ballasting intensity and bending stress in an underwater pipeline at different altitude water levels at the transition from operational loads and geometric characteristics of the crossing.
The research method is a theoretical study of the stress-strain state of an underwater pipeline under the action of operational loads and weights.
The dependences of ballasting intensity with weights of the underwater pipeline on the operational loads and the geometric characteristics of the transition at different elevations of the water level at the transition are obtained, and the highest bending stresses in the pipeline wall at the underwater crossing are determined. Recommendations to reduce the total longitudinal stress level in an underwater pipeline are given.
NEW SORBENTS BASED ON INDUSTRIAL WASTE FOR WASTEWATER TREATMENT FROM PETROLEUM PRODUCTS
Authors: Nazarov A. M. , Araslanova L. Kh. 
Published: July 2023

One of the most common types of ecotoxicants are petroleum products - an unidentified group of petroleum hydrocarbons and products of its processing. In this regard, the development of technology for obtaining new highly efficient and inexpensive sorbents for wastewater treatment from petroleum products (including those based on industrial waste) is an urgent problem. In this paper, a method of wastewater treatment from petroleum products using composite sorbents based on waste-tailings of Uchalinsky (SU), Buribaevsky (SB), Sibaysky (SS) mining and processing (GOK), and clay of the Talalaevsky deposit (G) and sodium humates (GN) obtained from the waste of the Tyulgan brown coal. The efficiency plants of purification was investigated using these sorbents of model wastewater contaminated with oil from the Vozeyskoye field of Usinsk Neftegaz LLC and real wastewater from the Ufa refinery of ANC Bashneft. It is shown that the efficiency of purification and the rate of adsorption of model wastewater containing petroleum products (8-50 mg/dm3) increases in a number of sorbents BAU - A < CC + G < SB ++ G < SU + G SU + G + GN (where BAU - A sorbent of comparison, activated carbon) and are maximal for GOK covered with GN. For real wastewater containing petroleum products of the Ufa refinery (3-625 mg/dm3), the adsorption activity increases in the series CC + G < SB ++ G < SU + G. Thus, the most effective sorbents for real and model wastewater containing oil and petroleum products are sorbents based on Uchalinsky GOK waste in a composition with clay (degree of purification 96.1 %), as well as SU modified GN (98.2 %).

Published: July 2023

The main problem in the development of the Priobskoye field is the search and implementation of technological solutions for the most efficient development of layers of ultra-low permeable reservoirs. A factor complicating the hydrocarbon production for such facilities is the low impact of flooding. These restrictions lead to high rates of decline in oil production, therefore, the most urgent issue is the search for an up-to-date technological solution aimed at improving the efficiency of field development.
This article is devoted to improving the efficiency of the development system in areas with low filtration and capacitance properties. It presents the results of research on the study of the construction of horizontal wells longitudinally and transversely to regional stress, followed by multi-stage hydraulic fracturing in the conditions of one of the largest fields in Western Siberia. The results of the research made it possible to determine an effective strategy for designing development systems in future areas.
The relevance of this work: the demand for the extraction of hard-to-recover reserves from reservoirs characterized by low permeability.

PIPE PROTECTION FROM CORROSION UNDER THERMAL INSULATION
Authors: Burkov D. V. , Gubaidullin M. G. 
Published: July 2023

Oil in the northern regions has a positive solidification temperature, so it needs to be heated to ensure pumping. Oil must have a high positive temperature along the entire pipeline length, which leads to a number of issues related to maintaining a positive temperature of oil in the pipeline along its entire length. Taking into account all the geological and climatic features of the Far North, for reliable and safe operation of the oil pipeline it is necessary to ensure the required temperature of the transported product, preventing pumping stops and preventing energy consumption overruns.
During the operation of pipelines with thermal insulation, moisture is formed in the thermal insulation layer for a number of reasons. Water gets under thermal insulation in two ways: as a result of condensation or comes from the outside. In addition, the thermal insulation itself can absorb and retain water, which subsequently turns out to be under insulation. Condensation may occur when the operating temperature of the surface changes.
Prolonged exposure to leaked or condensed moisture on the outer wall of the pipeline is the cause of corrosion under thermal insulation. The development of the process is quite complex, and has a number of features that distinguish it from conventional corrosion. The nature, speed and degree of damage to the surface are strongly influenced not only by the characteristics of the aquatic environment (hydrogen index, composition and concentration of dissolved electrolytes, etc.), but also by the ability of the insulating layer to release corrosive agents – chlorides and sulfates under the influence of water.
Chlorides and sulfates are water-soluble substances, their aqueous solutions have high electrical conductivity, which increases the corrosion intensity. Also the features of moisture accumulation of thermal insulation, which directly depends on the microstructure of the material are important.
During operation, the outer surface of the insulated pipelines is inaccessible for visual inspection without opening the insulation, and the beginning of corrosion in this case is difficult to determine, as a result, severe corrosion may occur with subsequent loss of integrity of the pipeline wall. The aggressiveness of the environment under thermal insulation is due to several factors: high temperature, the presence of moisture and chemicals.
The problem of metal corrosion is considered to be one of the most significant in safe operation of industrial facilities, as well as reducing the damage to the economics and the environment. Corrosion protection under thermal insulation is a serious problem requiring special attention.

Published: July 2023

As feições erosivas lineares podem ser compreendidas como a expressão da relação entre os elementos naturais e antrópicos. Assim, o objetivo do artigo foi analisar uma paisagem marcada por feições erosivas a partir de imagens de altíssima resolução geradas por um VANT DJI MAVIC Pro com sensor RGB CMOS com pixels efetivos de 12.35 M. Os resultados apontam para possibilidade de identificar o grau de dinamicidade dos taludes erosivos de voçorocas, assim como para um aumento no detalhamento dos sistemas erosivos vinculados às ravinas. A semelhança entre os fenômenos identificados em campo e os presentes na imagem também é interessante e constitui-se em um fator que reduz drasticamente o ônus com as etapas de reambulação. Algumas limitações foram identificadas, como a necessidade de verificações em campo para caracterização de rupturas topográficas com afloramento d’água e limitações no processo de fotointerpretação, causadas, por exemplo, por obstrução no campo de visada.
