Gastronomy tourism plays a very important role in a country's economy. Gastronomy tourism has been proven to have a positive impact on competitive dynamics and the long-term viability of a destination, as well as the local economy and regional development. Therefore, this study aims to examine the influence of gastronomic tourism on tourist satisfaction. Apart from that, this study also tested the influence of tourist satisfaction on revisit intention and recommendation intention. This study involved 462 domestic tourists in Surabaya. Data were analyzed using Structural Equation Modeling (SEM) analysis with SmartPLS. This study reveals that the quality of gastronomy tourism influences tourist satisfaction and will ultimately encourage potential revisit intention and recommendation intention for tourists to visit gastronomy tourism. Other findings show that tourist satisfaction mediates the effect of gastronomy tourism quality on tourists' revisit intention and recommendation intention to visit gastronomy tourism. The results of this study provide important implications for gastronomy tourism businesses to build tourist satisfaction by improving the quality of gastronomy tourism. By paying attention to and improving the quality of gastronomy tourism, a country can build a positive image, increase competitiveness and support economic growth through a sustainable tourism industry.

The methods of radar with narrow-band radiation by switching the antenna pattern around the equi-signal zone or in orthogonal planes are considered, which significantly (by tens of dB) reduce the power of the transmitter by narrowing the receiver bandwidth. The range to the target is determined by calculating the phase difference of the received signal at the switching frequency of the reference signal of this frequency by a stabilized quartz oscillator. It is shown that it is possible to increase the accuracy of measuring the range by introducing two scales: coarse, determined by the switching frequency, the wavelength of which corresponds to a double range to the target, and accurate, with a higher switching frequency.Since the required radiation power of the transmitter in the narrowband case is determined by the noise immunity of phase measurements, then at a given range of the system, by increasing the power of the transmitter, it is possible to reduce the error of measuring the range. As is known, in the pulsed radar method, the accuracy of the range estimation is limited by the duration of the emitted pulse and practically does not depend on the power of the transmitter. For this reason, the radars used do not allow for the accuracy of estimating their coordinates better than tens of meters. A possible solution to such a problem is the use of continuous signals with partial modulation, but requiring a wide bandwidth of receivers determined by frequency deviation, which significantly reduces the noise immunity of the system. The disadvantage of the narrowband radar method described below with spatial signal modulation is the inability to distinguish targets located at the same azimuth. However, in a number of tasks, for example, when used in altimeters, over-the-horizon radar, high-precision radio geodesic measurements, etc., the radar options described in the article make it possible to increase the accuracy of measuring the range not achieved by other methods. The main advantage of the new method is: stealth; high noise immunity; minimum radiation power of the transmitter; the ability to quickly change the carrier frequency, independence from the speed of movement of the target, since the measurement of the signal phase is determined only by the switching frequency.

Desplazamientos migratorios y migrantes en Caterva de Juan Filloy
Authors: Guevara Martina
Published: March 2024

Nos interesamos por las configuraciones temáticas y estructurales de los migrantes y la migración en Caterva de Juan Filloy (1937). En primer lugar, contextualizamos el papel de la migración en el modelo nacional de la Argentina desde su momento fundacional hasta la década del 30. En segundo lugar, nos detenemos en los años 30 para establecer los vínculos entre una configuración específica de la migración y los migrantes en Caterva, y las particularidades de un contexto en el que se masifican los discursos xenófobos y se produce un giro restrictivo en la política migratoria. Nuestro análisis se articula a partir de tres ejes: la criminalización de los migrantes por su ideario político, la desmitificación y reconversión del mito de la nación agraria y el crisol de razas y, finalmente, el trazado de un nuevo recorrido migratorio que no tenga como centro a Buenos Aires.

Equivalencies Between Ad Hoc Strategies and Multivariate Models for Meta-Analysis of Dependent Effect Sizes
Authors: Pustejovsky James E. , Chen Man
Published: March 2024

Meta-analyses of educational research findings frequently involve statistically dependent effect size estimates. Meta-analysts have often addressed dependence issues using ad hoc approaches that involve modifying the data to conform to the assumptions of models for independent effect size estimates, such as by aggregating estimates to obtain one summary estimate per study, conducting separate analyses of distinct subgroups of estimates, or combinations thereof. We show that these ad hoc approaches correspond exactly to certain multivariate models for dependent effect sizes. Specifically, we describe classes of multivariate random effects models that have likelihoods equivalent to those of models for effect sizes that have been averaged by study, classified into subgroups, or both. The equivalencies also apply to robust variance estimation methods.
Multi-stage attacks Concepts Detection and Defense
Authors: Neagu Delia Daniela
Published: March 2024

We live in a fast-paced world, surrounded by all kinds of technologies. However, unfortunately these technologies present weaknesses that exposes us to malicious attacks. The attackers are developing their skills and continuously find new ways of penetrating into systems where they have unauthorized access. These attacks can cause data breaches and losses and can even cause physical damage to the systems. By getting access to sensitive data, the attacker may steal the bank account details of an individual, their identity and even invade their privacy, which may cause a serious psychological impact. These attacks can cost companies huge financial losses, damage their reputation, and it might even place them in a situation where they have to face legal consequences for not being able to protect their customer’s data. This report will discuss multi-stage attacks, which is a very dangerous type of attack, because it’s not easily detectable. This attack, as it can be referred from the name, happens in multiple steps, where each step executed by its own does not seem malicious. However, all these phases executed together will cause great harm. This report will also present several proposed detection methods, as well as defence recommendations against this type of attack.

Reintegrating Money into Monetary Policy
Authors: Ambler Steve
Published: March 2024

Actuellement, les agrégats monétaire ne jouent aucun rôle dans l'analyse de la politique monétaire par la Banque du Canada ou dans sa communication au public. Cet article montre que négliger les agrégats monétaires est justifié lorsque la banque centrale atteint sa cible en moyenne, lorsque l'inflation est stable, et lorsque les attentes inflationnistes sont bien ancrées. Dans ce cas, le seul prédicteur fiable de l'inflation à un horizon approprié est la cible d'inflation elle-même. Par contre, en périodes d'inflation élevée comme celle que nous avons vécue depuis 2021, la monnaie contient de l'information concernant l’évolution de l'inflation qui est dangereuse d’écarter. Néanmoins, il faut interpréter cette information de façon judicieuse puisque la vitesse de circulation de la monnaie dépend des attentes et du degré de permanence des chocs monétaires.

Note des rédacteurs : Le premier volume de Canadian Public Policy/Analyse de politiques a été publié en 1975. Ce volume-ci est le cinquantième.

Sources of Distortion During Quench Hardening Studied Using Computer Modeling
Authors: Li Zhichao , Lynn Ferguson B. , Sims Justin , Yu Tianyu
Published: March 2024

Quench hardening is a transient thermal stress process with phase transformations. It is inevitable that a component will go through plastic deformation due to phase transformations, which will lead to distortion in the hardened part. Understanding the sources of distortion is necessary in designing the heat treat process and component configuration to obtain a product with greater dimensional accuracy. It is worth mentioning that consistent distortion can be compensated by adjusting the part dimensions prior to hardening. The possible sources of distortion include residual stresses prior to hardening, heating rate, austenitizing temperature, soaking time, quenching rate and uniformity, and possible tooling constraints, etc. The significance of these effects varies according to the part geometry and heat treatment process. Characterization of material properties and the development of computer modeling made it possible to understand the material and component responses during quench hardening, which is the key to process improvement and part configuration optimization. In this paper, the hardening process of a simplified bevel gear with thin-wall feature made of AISI 9310 is analyzed using DANTE, and the effect of tooling used in a press quench on distortion is investigated. The causes of distortion are analyzed through the material response aspect using the modeling results.

Published: March 2024

The most common probe used for cooling curve analysis of quenchants is a 12.5 mm diameter x 60 mm Inconel 600 cylindrical probe with a Type K thermocouple inserted into the geometric center. The time-temperature cooling curve is obtained at this position and is the basis for national and international standards including ASTM D6200, D6482, D6549, ISO 9950 and others. However, greater insight into the quenching process would be possible if a better profile were available for the uniformity and wetting kinematics of the quenching process. An alternative probe design, proposed by Prof. H.M. Tensi and his colleagues, utilizes a cylindrical 15 mm diameter x 45 mm flat-bottom shape with four thermocouples. One thermocouple is inserted to the geometric center of the probe at 22.5 mm from the bottom. The remaining three thermocouples are located 2 mm below the surface of the probe at 2 mm, at 15 mm, and at 30 mm from the bottom. This alternative probe design was used to characterize the usual centerline cooling curve properties as well as rewetting properties of two vegetable oils, palm oil and canola oil, a commercial fast petroleum oil quenchant, and a conventional petroleum oil quenchant. The probe construction, use, and quenching characterization results are reviewed in this paper.
Re-Wetting Behavior and Heat Extraction during Laboratory-Scale Quenching Experiments using Two Probe Geometries
Authors: Cruces-Reséndez R. , Hernández-Morales B. , Durán García E.I.
Published: March 2024

The effect of probe geometry on the re-wetting behavior and heat extraction of cylindrical probes during forced convective quenching in laboratory-scale equipment was studied. Flat-end and hemispherical-end cylindrical probes made of AISI 304 stainless steel and instrumented with type-K thermocouples were considered. Two free-stream velocities (0.2 and 0.6 m/s) and two initial probe temperatures (850 and 950°C) were studied. The quench medium was water at 60°C. The inverse boiling curves and videos obtained showed that the vapor film stage lasts longer when using flat-end probes. This delay in the start of re-wetting shifted the cooling curves to the right and favored the probe surface to reach lower temperatures before the start of re-wetting which resulted in slightly higher values of the wetting front velocity. It is shown that the hydrodynamics of the flow around the probe end is responsible for the differences observed between the two geometries.

Published: March 2024

High frequency welding is a thermo-mechanical process that relies on precise heat input as well as mechanical control as strip edges are heated and forged together to result in a seam weld. Heat input can be defined as a way of characterizing the temperature distribution at the strip edges prior to forging them together. Heat input is affected by several process variables ranging from raw material properties to welder settings and weld area setup. These are summarized in this paper, with special attention on the effects of welder frequency, welder power, line speed, and steel alloy composition on heat input and the resulting weld quality. Frequencies in the range of 100 – 800 kHz are considered. Data from tube mills (including general data and controlled on-the-mill experiments) and laboratory evaluations are included in this paper.

Published: March 2024

In this work, tungsten carbide coatings are deposited by low-pressure cold spraying in order to assess the influence of powder compressive strength and binder materials on coating properties. Powder compressive strength was measured with a micro-compression tester, and cobalt and FeCr in different proportions were used as the metal binder. It was found that compressive strength affects coating hardness as well as deposition efficiency and that the optimum value for deposition efficiency is about 200 MPa. The results also indicate that dense coatings can be produced with either binder material, although coatings with an FeCr binder are the hardest.

Published: March 2024

This study compares two methods for modeling the breakup of droplets during suspension plasma spraying. One is based on Taylor analogy breakup, the other on Kelvin-Helmholtz Rayleigh Taylor breakup. A three-dimensional model with two-way coupling is used to simulate flow within the plasma plume and interactions between suspension droplets, and a Reynolds stress model is used to simulate gas field turbulence. After breakup and vaporization, the solid suspended particles are tracked through the domain to determine the characteristics of coating particles. The numerical results are validated against experiments using high-speed imaging.

The shortage of high-quality stone materials for road construction requires the search for alternative materials, the use of which will ensure the proper quality of road pavements. Metallurgical slags are a valuable raw material for the construction industry in general and for road construction in particular due to its properties. However, they are characterized by heterogeneity of composition in different batches and, as a result, physical and mechanical characteristics that change over time. The use of various methods for stabilizing that kind of technogenic raw materials makes it possible to obtain stone raw materials with specified properties. The paper considers the effect of crystal-chemical stabilization of slag in the process of draining on the complex of standardized indicators of the final material – slag rubble. Stabilization of furnace slag during draining made it possible to improve the following standardized indicators: compressive strength grades from 800 to 1200, abrasion grades from IV to II, structural stability of slag against decay from StS2 to StS1, frost resistance to F50. The physical and mechanical properties of the resulting stone material make it possible to use it for the construction of base layers and as part of composite materials for the construction of coatings in road pavement structures.

The work execution is aimed at accelerating the introduction of advanced technologies in construction in terms of creating scientific and technical groundwork for the development of additive construction production and the development of the domestic regulatory and technical base in the field of construction 3D printing.
Method of Redevelopment of Underground Mining Facilities
Authors: MANKO A.V.
Published: March 2024

Mining is a set of industrial branches engaged in exploration, extraction, primary processing and obtaining the initial semi-finished product of elements related to minerals. Deposits are ore, non-metallic and alluvial. These deposits are mined by open pit and closed pit methods. After the end of underground operations, empty mine fields remain, which on the surface are labeled as exclusion zones. The problem of cave-in zones, under which the waste mine fields of the mining industry are located, has been particularly acute for decades. These mines are located not only under the industrial zones of populated areas, but also under residential and public areas and cause irreversible transformation of the natural environment, which leads to catastrophic consequences. Transformation of underground space is the main task of redevelopment of industrial areas of this kind. It is possible to build underground structures for other purposes in worked-out mines. Due to the fact that these structures will be maintained and operated, the change in the secondary stress fields in the mountain massif will not have such catastrophic consequences as in the case of alienation-collapse zones. Besides, the reuse of worked-out workings is economically more favorable due to the fact that sinking will be minimal. In this paper only underground mining complexes and the possibility of their reuse will be considered.
Functional Alterations in Macrophages After Hypoxia Selection
Authors: Degrossoli Adriana , Giorgio Selma
Published: March 2024

Regions of low oxygen tension are common features of inflamed and infected tissues and provide physiologic selective pressure for the expansion of cells with enhanced hypoxia tolerance. The aim of this study was to investigate whether macrophages resistant to death induced by hypoxia were accompanied by functional alterations. A mouse macrophage cell line (J774 cells) was used to obtain subpopulations of death-resistant macrophages induced by long-term exposure to severe hypoxia (<1% O2). The results indicated that exposing J774 macrophages to periods of severe hypoxia results in the selection of cells with phenotypes associated with the modulation of heat-shock protein 70 kDa (HSP70) expression, tumor necrosis factor-α (TNF-α), and nitric oxide (NO) production and reduced susceptibility to parasite Leishmania infection. Thus, we suggest that hypoxia-selected macrophages may influence the outcome of inflammation and infection. Exp Biol Med 232:88–95, 2007

Published: March 2024

Endothelin (ET)-11–21 is known to play an important role in the pathogenesis of acute ischemic arrhythmia. In the present study, we attempted to determine whether administration of ET-11–31 would result in arrhythmia in perfused isolated rat hearts. Forty-eight Sprague-Dawley rats weighing ~250–350 g were randomized into 6 groups. Heart was isolated and perfused in a Langendorff mode. The effects of ET-11–31 on arrhythmia, heart rate, coronary flow, and heart function were analyzed. Perfusion with 1 n M ET-11–31 resulted in frequent ventricular ectopic beats (VEBs) and ventricular tachycardia (VT). Overall VEB was 128.0 (~66.0–1015.0), and the arrhythmia score (AS) was 2.18 ± 0.87; both were significantly higher than those of the control group ( P < 0.01). Pretreatment with perfusion of 10 n M of the ETA-receptor antagonist BQ123 markedly attenuated the occurrence of VEB and VT induced by ET-11–31. AS in 10 n M BQ123 group was significantly lower than that in 1 n M ET-11–31 group ( P < 0.01). The arrhythmia induced by 1 n M ET-11–31 was partially but significantly reduced by phosphoramidon (1 μ M), a neutral endopeptidase/ET-converting enzyme inhibitor. ET-11–31 per se caused arrhythmia in perfused isolated rat hearts. This arrhythmogenic action is in part mediated by ETA receptor and may be attributed mainly to the conversion of ET-11–31 to ET-11–21.
Improvement of Machine Vision Video Signal Processing Algorithm for Higher Accuracy in Extended Object Speed Measurements
Authors: Diyazitdinov R. , Vasin N.
Published: March 2024

Machine vision systems are widely used for monitoring of the railway infrastructure condition. High reliability of machine vision systems allows using them not only for video recording but also for automation of technological processes. One of the important tasks in the process automation is measurement of an extended object speed (rail-road cars, electric locomotives and rolling stock). Some systems have a requirement to estimate speed in real time (braking of cars at a shunting yard). In this case the speed is calculated by two adjacent frames to ensure the minimum delay for measurement. However, the image of an extended object can be uninformative (image fragments are uniform in brightness), the weather can cause interference. It leads to high speed estimation error. This article describes the improvement for the existing real-time algorithm which allows for higher accuracy in speed measurements. The improvement implies selection of an informative image area corresponding to an extended object. A comparative analysis of the existing and improved algorithm showed a significant reduction in the estimation error in speed measurements.

Analysis of End-to-End Delay in the Transport Segment of Fronthaul 4G/5G Networks Based on TSN Technology
Authors: Roslyakov A. , Gerasimov V.
Published: March 2024

One of the characteristic features of 4G/5G mobile networks is the spatial separation of functional blocks.  The corresponding segments of the xHaul transport network are used to connect these blocks. One of them is the Fronthaul front end segment, which connects remote radio equipment with their control equipment. The data streams of standard CPRI/eCPRI radio interfaces in this segment impose strict requirements on the quality of service and, above all, on delays. To meet these requirements, it was proposed to use in the Fronthaul segment Ethernet bridge network based on the technology of time-sensitive networks TSN (Time Sensitive Networking), which provides determinated delays, reliable packet delivery and high accuracy of synchronization of nodes in the network. The IEEE 802.1CM standard describes profiles of TSN networks that defines the functions, options, configurations, default values, protocols and procedures of bridges, stations and local networks required to build the Fronthaul transport segment. The article presents a methodology for determining the maximum end-to-end traffic delays of standard CPRI/eCPRI radio interfaces in the Fronthaul segment of 4G/5G networks, built on the basis of TSN technology, in accordance with the requirements of IEEE 802.1CM standard. Two main components of end-to-end delay are identified ‒ delays in TSN bridges and delays in xEthernet channels. For high-priority traffic flows of CPRI/eCPRI radio interfaces in bridges, characteristic cases of mutual influence of flows arriving simultaneously at different input ports are given. An example of numerical calculation is given, which allowed to determine the permissible physical length of the Fronthaul segment at a given boundary end-to-end delay of transmission of high-priority traffic.

У статті розглянуто сутність поняття «конфлікт» та визначено, що існують наступні підходи до його розуміння: деструкція відносин / боротьба; ситуація протиборства / конфронтації; засіб розв‘язання суперечностей; зіткнення різноспрямованих сил; стан взаємовідносин. Наведено авторське визначення поняття «конфлікт», зокрема під конфліктами слід розуміти ситуацію, коли відбувається зіткнення інтересів двох чи більше сторін, які мають протиріччя в цілях, інтересах, потребах, цінностях, переконаннях тощо. Конфлікти можуть виникати у різних ситуаціях, зокрема розбіжності в цінностях та переконаннях, конкуренція за ресурси, несумісність темпераментів та характерів, стресові ситуації, несумісність стилів роботи, амбіційність, культурні та етнічні відмінності, розбіжності в уявленнях і цілях тощо. Конфлікт може виникати у будь-якій сфері життя – від особистих відносин до міжнародних відносин, і мати різні форми прояву, починаючи від непорозумінь і закінчуючи відкритими конфліктами. Управління конфліктами на підприємстві є важливим для забезпечення продуктивності та гармонійної співпраці між співробітниками, врахування інтересів всіх сторін. Окрім того управління конфліктами залежить від етапів, до яких належать виявлення конфлікту (перший етап), зокрема необхідно розпізнати наявність конфлікту на підприємстві, який реалізується шляхом виявлення напруження у взаємовідносинах на підприємстві, зниження продуктивності або погіршення комунікації між працівниками. Другий етап – це дослідження причин виникнення конфлікту, зокрема це може бути різниця в уявленнях, конкуренція, непорозуміння тощо. Третій етап – це планування стратегії вирішення конфлікту, тобто розробка плану дій для вирішення конфлікту, і може включати різні способи зменшення напруги, пошук компромісу або впровадження нових політик та процедур. Четвертий етап – це реалізація стратегії управління конфліктами, що передбачає здійснення плану дій з метою вирішення конфлікту. П’ятий етап – оцінка та перегляд результатів. Після вирішення конфлікту важливо оцінити результати застосованих стратегій. Якщо конфлікт було успішно вирішено, варто проаналізувати, що саме принесло успіх, а якщо не вдалося досягти успіху, варто зрозуміти причини та внести корективи у стратегію. Шостий етап – створення профілактичних заходів з метою уникнення подібних конфліктних ситуацій у майбутньому.
