El Surgimiento de la empresa hotelera moderna en la periferia
Authors: Vargas Pacheco Cristina , Cerna Sabogal José 
Published: June 2024

En el extremo norte peruano, en Piura, región con una dinámica económica sustentada en la explotación agrícola y de hidrocarburos, así como en el comercio; la inversión en el rubro hotelero se realizó de forma tímida, interviniendo capitales estatales como privados. En ese tránsito, coexistirán establecimientos que supieron transformarse con el devenir de las décadas, como es el caso del hotel Colón (ca. 1890), con aquellos imbuidos por una lógica hotelera moderna, como el hotel de Turistas (1943) y el hotel Cristina (1954). La apuesta privada por la empresa hotelera no siempre se condijo con los retornos esperados, siendo las dificultades económicas, moneda común de la vida de estos emprendimientos.
Este trabajo se inscribe dentro de la narrativa de la historia del turismo en el Perú, pero desde una perspectiva regional. El objetivo de esta investigación es comprender cómo se va construyendo la lógica turística en las regiones peruanas, en este caso, a partir de una aproximación a una parte fundamental de esta industria, como es la hotelería, lo que realizamos a través de una revisión de esa suerte de “evolución” de los alojamientos locales mediante la reconstrucción del devenir de los tres casos arriba enunciados, durante la primera mitad del siglo XX. Para esta investigación se empleó una metodología cualitativa, basándonos en las fuentes archivísticas y hemerográficas existentes, mucha de ella dispersa, así como en la escasa bibliografía sobre el tema del turismo en las regiones, especialmente en la estudiada, en el período atendido. Así, a partir de una mirada a casos concretos, se propone un acercamiento a un aspecto escasamente abordado de la historia regional, de un área generalmente atendida por su economía extractiva.

Authors: Shamansurova E. A. , Kostinov M. P. 
Published: June 2024

Assessment of the effect of vaccination against Streptococcus pneumoniae on the serotype spectrum of pneumococcus.Materials and methods. Bacteriological study of nasopharyngeal mucus of 247 healthy children attending kindergarten, as well as serotyping of the obtained samples. The specific immune response to various serotypes of S. pneumoniae was determined by ELISA.Results. A bacteriological study of nasopharyngeal mucus from 247 healthy children attending kindergarten showed that S. pneumoniae was isolated from 35.6% (20) of practically healthy children. When serotyping the isolated samples, the most common pneumococcal serotypes were 15A/F, 6 A/B, 9 A /V and 9 F, then in frequency 5 and 7 A/F, 23F serotypes. A study of specific antibodies to pneumococcus in vaccinated children showed a high level of immune response. Thus, it was found that vaccination with commercial pneumococcal vaccines protects the majority of vaccinated children. To assess the effectiveness of vaccination, it is necessary to study the circulation of serotypes in children after vaccination.

Background. Аnesthesia for carotid endarterectomy can be used as a combined endotracheal anesthesia, regional anesthesia, and also a combination of combined endotracheal anesthesia with regional anesthesia. Studies have shown that the combination of endotracheal anesthesia with regional anesthesia significantly reduces the need for analgesics after surgery, and the use of levobupivacaine as a local anesthetic reduces the incidence of adverse events.Aim. To compare the advantages and disadvantages of the combined anesthesia (the combination of endotracheal with regional anesthesia) and the regional anesthesia with sedation using levobupivacaine.Material and methods. In a prospective single-center study, patients were allocated into 2 groups. In group 1 (n=40), a general anesthesia was performed using desflurane in combination with the regional anesthesia of the superficial cervical plexus. In group 2 (n=40), a blockade of the superficial cervical plexus and deep cervical plexus was achieved. Levobupivacaine was used as a local anesthetic in both groups.Results. The study showed a significantly (p<0.05) greater number of intraoperative hypertension (BPsys more than 170 mm Hg) episodes in patients of group 1 making 10(25%) versus 4(10%) in group 2, and the presence of hypotension defined as blood pressure less than 90 mm Hg in 5 (12.5 %) patients of group 1 during surgery. In addition, tachycardia (heart rate more than 90 beats per minute) was significantly (p <0.05) more often recorded in group 1: in 8 patients (20%) versus 4 (10%) in group 2. In both groups 1 and 2, adverse events were noted: pain in the intervention area in 4 (10%) patients of group 2, positional discomfort in 3 (7.5%) patients of group 2, sensation of shortness of breath and anxiety in 1 (2.5%) patient of group 2, postoperative nausea in 3 (7.5%) patients of group 1, and postoperative vomiting in 2 (5%) patients of group 1. The time spent in the operating room was significantly longer (p<0.05) in group 1 than in group 2: 110±15 minutes versus 75±12, respectively.Conclusion. Regional anesthesia reduces the patient's time in the operating room, but the presence of "operating room effect" reduces patient satisfaction compared to general anesthesia in combination with regional anesthesia. Levobupivacaine is effective and safe for both the isolated regional anesthesia and as a component of the combined endotracheal anesthesia for carotid endarterectomy.

Introduction. In conditions of the Emergency Cardiology Department, a timely and differential diagnosis of myocardial pathology is especially important in the absence of visible focal changes and significant coronary artery stenosis. This group of patients includes recipients of a transplanted heart, when it is difficult to count on the high sensitivity of perfusion images alone. This can be explained by the diffuse, balanced distribution of ischemia.Objective. To present the possibilities of perfusion myocardial single photon emission computed tomography synchronized with electrocardiography for a detailed assessment of the functional condition of both ventricles of the transplanted heartMaterial and methods. We have presented three clinical case reports of the patients with different pathology of the transplanted heart who referred themselves to the emergency cardiology clinic and underwent electrocardiographysynchronized perfusion myocardial single photon emission computed tomography for diagnostic purposes.Results. In all the cases presented, the radionuclide study influenced making the diagnosis and changing the treatment tactics. In the first case, it was possible to identify focal myocardial changes, for which coronary angiography and percutaneous coronary intervention with thromboextraction were immediately performed. In the second case, the image analysis reflecting the function of the myocardium (polar maps of wall movement and systolic thickening) allowed us to note a low efficacy of treatment for the transplanted heart rejection. In the third clinical case, the initial single photon emission computed tomography suggested the inflammatory nature of changes in the myocardium, which was verified by the results of endomyocardial biopsy.Conclusion. In the presented clinical cases, the urgently performed electrocardiography-synchronized perfusion myocardial single photon emission computed tomography made it possible to perform invasive interventions in time and thereby contribute to the recovery of the graft functional state and patient's condition improvement.

Three Root Causes for the Impasse in Reputation Measurement for Higher Education Institutions
Authors: Redler Joern , Morschheuser Petra 
Published: June 2024

Abstract
Monitoring the reputation of Higher Education Institutions is a key challenge. Despite decades of research and theory in Higher Education marketing addressing this issue, a definitive method for capturing and monitoring reputation of such institutions has yet to emerge. This paper argues that research into a theoretically sound method for capturing and monitoring the reputation of Higher Education Institutions has stalled due to three significant obstacles: (a) the complexity of defining the construct of reputation itself, (b) ongoing disputes regarding the appropriate methods of measurement for the constructs of reputation, (c) insufficient tailoring of the construct of reputation to the distinctive nature of Higher Education Institutions.
Degradation of hydroxychloroquine in aqueous solutions under electron beam treatment
Authors: Kabasa Stephen , Sun Yongxia , Bułka Sylwester , Chmielewski Andrzej G. 
Published: June 2024

Abstract
Hydroxychloroquine (HCQ), a 4-amino quinoline derivative, has antimalarial and anti-inflammatory activity and was most recently proposed in the treatment of SARS-COVID-19. Its pharmacokinetics and toxic side effects necessitate the monitoring of its presence in the environment and its removal from wastewater. In this study, HCQ was removed from an aqueous solution with a removal efficiency of between 80% and 90% under electron beam (EB) irradiation. The degradation of HCQ was propagated by reactions involving both the hydroxyl radical and aqueous electron. The degradation was observed to follow a pseudo-first-order kinetic reaction. The applied radiation dose, pH, and initial HCQ concentration were influential in the degradation efficiency under EB irradiation. Acidic and alkaline pH favored the removal of HCQ under EB irradiation. Even though the initial HCQ was successfully degraded, it was not completely mineralized. The TOC and chemical oxygen demand (COD) remained at a relatively stable level following EB irradiation of the aqueous solutions. This is attributed to the formation of other organic compounds that were not degraded under the investigated experimental conditions.
Influence of the type of fuel used on the content of gamma radionuclides in the soot from the smoke ducts of the home furnaces
Authors: Stobiński Marcin 
Published: June 2024

Abstract
This paper presents the results of the measurements of gamma radioactive isotopes in soot samples from 15 different chimneys of household furnaces fired with various types of solid fuel. Soot samples were collected by the chimney sweep during the mandatory periodic cleaning of the chimneys. The γ-spectrometry technique using the high-purity germanium (HPGe) detector was employed for radiometry of the above-mentioned soot. It was found that the determined activity of gamma isotopes in soot is at a level similar to that in fly ash from power plants around the world. Artificial 137Cs was detected only in the soot from the combustion of biofuel or mixed fuel. The results obtained were chemometrically analyzed to find the relationship between the fuel used and the gamma isotope content in the soot. The analysis of 137Cs, 40K, 228Th, and 226Ra is sufficient to differentiate between the soot obtained and tested, and it varied with the fuel type burned (fossil fuels/biofuels).
Ontological and philosophical basis of the causal status of ethnopsychological idiosyncrasy in translation/interpretation
Authors: Iovenko V. A. 
Published: June 2024

The causal status of the phenomenon of ethnopsychological idiosyncrasy is considered in the article in relation to the process of translation in the format of activity ontology. In translation studies, activity ontology uses not only comparison of idiomatic units and structures, but also, for research purposes, draws on textual, cultural, psychological, philosophical, pragmatic, cognitive and other aspects and phenomena which underlie translation process as a unique manifestation of interlingual and intercultural mediation. The activity paradigm opened up new prospects for studying fundamental problems of the translation theory. Among these problems are factors (determinants) of an adequate translation that are prerequisites of a translator’s work. Ethnopsychological idiosyncrasy, the concepts world picture and closely connected world idiomatic picture are considered from philosophical, and linguistic perspectives as well as from the point of view of translation theory.The article proves the causal status of ethnopsychological idiosyncrasy as one of the most important factors determining translation activity. In order not to “lose yourself ” in the idiomatic picture of the target language, which is conditio sine qua non for an adequate translation, translators should possess professional skills to overcome conceptual stereotypes and peculiarities of the ethnic and psychological idiosyncrasy in the source language. If it doesn’t happen, translations are perceived as not quite natural and therefore are not fully adequate.The differences in ethnic and psychological peculiarities in the communities, which enter into bilingual communication, form an ethnic and psychological differential, which should be neutralized during translation.The author established certain manifestations of the Spanish ethnic and psychological idiosyncrasy relevant for the translator’s communicative activity in the Spanish-Russian idiomatic combination.
Getting a handle on a Hansard with Python and NLTK, or how to tame the linguistic picture of British politics with NLP
Authors: Gagarin S. N. 
Published: June 2024

The article proposes an optimised starter’s set of basic Python and NLTK (Natural Language Toolkit) methods that are essential in the analysis of massive textual corpora conducted as part of research investigating linguistic images of the world. The need to specify and detail these applied techniques stems from the nature and scope of the inexorable challenges confronted by contemporary cognitive linguistics and lexicology in the realm of unstructured big data analysis. Their viability and practical value are demonstrated in a series of illustrative examples where they are applied to the processing of continuous parallel diachronic corpora of Hansard that capture the discourse of both chambers of the British parliament produced in the years 2006-2023 and jointly amounting to over a third of a billion tokens.The article suggests that the methods it outlines and classifies can be seen as forming an indispensable minimum of IT competences that is capable of delivering a substantial boost to the level of research both as regards its overall quality and its competitive edge. The proposed toolkit includes an essential set of instruments for target vocabulary processing as well as for the assessment and visualisation of word and phrase frequency and collocation.The author presumes that, urged by the need to keep abreast of prevailing trends, the contemporary Russian researcher of linguistic images of the world is highly likely to find themselves compelled at some point to embrace the quantitative analysis methods made possible by combining Python and NLTK. As part of its substantial and varied range of benefits, the latter would arguably help them design and customise research protocols, adapting them with ease and versatility. Lastly and most importantly, the author suggests that Python and NLTK skills may serve as a comfortable gateway towards eventually upgrading one’s linguistic research to cutting-edge global standards of technological sophistication and marketability.

Responsive Maneuver Planning for Sun-Synchronous Repeating Ground Track Orbits
Authors: Treblow Shalom , McGrath Ciara N. 
Published: June 2024

This paper investigates the suitability of sun-synchronous orbits (SSOs) as an injection location for responsive, maneuverable spacecraft. This work identifies a range of near-circular, repeating ground track (RGT) orbits that can be easily maneuvered into from SSOs. Four orbits that are simultaneously sun-synchronous and have an RGT are found, which could deliver high-frequency imagery of a target with constant lighting conditions. A method for maneuvering between RGT orbits that are targeting different regions using high-thrust impulse propulsion is also presented. This method is used to model two possible case studies for targeting regions on demand starting from an SSO injection orbit. In a comparative case study with a method that used low-thrust propulsion to move between targets, it was found that the method outlined in this paper required 55% less [Formula: see text]. A case study considering urgent response times showed that RGTs covering targets could be reached in as little as 4 h from any starting location, but this could require extremely large amounts of [Formula: see text] (upward of 1 km/s), while any global target could be viewed within 18 h with a maximum [Formula: see text] of [Formula: see text].
Unsteady Surface Pressure Characterization on Launch Vehicle in Liftoff Configuration

Published: June 2024

Acquisition of unsteady pressure using remote scanners can provide practical advantages over making the same measurements directly using flush-mounted pressure transducers. However, pneumatic distortion of the signal is introduced by the tubing between the sensing module and surface port. This typically limits the usefulness of such measurements to averaged, steady data only, restricting the application of pressure scanners for unsteady pressure measurements in wind-tunnel and flight-testing applications. In this work, unsteady pressure on the surface of a 1.75%-scale model of the NASA Space Launch System Block 1B Cargo vehicle was remotely measured using an electronic scanning pressure module at the NASA Langley Research Center 14-by 22-Foot Subsonic Tunnel. Subsequent reconstruction using an empirically tuned, Wiener-filtered inverse transfer function produced excellent agreement compared to nearby surface-mounted transducers within a usable bandwidth of approximately 500 Hz. Interactions between the launch vehicle and the support tower produced strong oscillations that were absent in the vehicle-alone configuration, and it is likely that the wake interaction leads to a resonant flow response when the launch tower is immediately downstream of the vehicle.

Published: June 2024

Measurements were performed in the T6 Stalker facility operating in Aluminum Shock Tube mode for conditions relevant to Titan entry. Spatially and spectrally resolved radiation emitted from a high-temperature test gas behind a normal shock was recorded by means of emission spectroscopy. For Titan atmospheric entry, the main radiator of interest is cyano radical, formed in the nonequilibrium region behind the shock. The tests reported in this work measured radiation at velocities from 3.1 to 8.5 km/s and freestream pressures of 13, 20, and 133 Pa at a nominal composition of 98% [Formula: see text] and 2% [Formula: see text]. These shock layer radiation experiments employed an optical emission spectroscopy system on each side of the facility to allow two spectral regions to be measured simultaneously for each test, covering the spectral range of 200–900 nm. The present work provides a new, comprehensive benchmark set of data relevant to Titan entry studies.
