Authors: Aprilizia Dwi Suryaning Ayu , Andarini Ismiranti , Hafidh Yulidar
Published: October 2022

Background: COVID-19 has spread all over the world and became a global pandemic. In Indonesia, COVID-19 has officially defined the non-natural disaster of COVID-19 spread as national disaster in April 13th 2020. COVID-19 cases are predominant in adult population with higher severity particularly if accompanied with comorbidities resulting in a relatively high mortality rate. However, some recent studies showed that children are at a similar or higher risk to COVID-19 compared to adults. This study aims to evaluate the predictors of mortality in pediatric COVID-19 cases.Subjects and Method: This study used a cross-sectional design using data from medical records of pediatric patients with confirmed COVID-19 who were hospitalized in the isolation ward of Dr Moewardi General Hospital from March 2020 to August 2021. All variables with significant result in the bivariate analysis were analyzed using multivariate logistic regression. Data were analyzed using SPSS (IBM SPSS Statistics version 25) with significance of p value of < 0.05.Results: Results of this study showed that age 10-17 years (OR= 16.26; 95% CI= 1.47 to 179.56; p= 0.023), the use of oxygen mask (OR= 45.89; 95% CI = 5.39 to 390.58; p <0.001), and the use of continued oxygen therapy (OR= 181.48; 95% CI=11.25 to 2927.80; p <0.001) are predictors of mortality in pediatric patients with confirmed COVID-19.Conclusion: Age 10-17 years, use of oxygen mask and advanced oxygen therapy are predictors of mortality in pediatric patients with COVID-19 hospitalized in Dr Moewardi General Hospital Surakarta.Keywords: mortality, COVID-19, pediatric.Correspondence:
La investigación bioacústica de las aves del Archipiélago de Revillagigedo: un reporte de avance
Authors: Baptista  Luis F. , Martínez Gómez Juan E.
Published: October 2022

Las canciones de las aves se han convertido en herramientas importantes para estudios taxonómicos, de ecología del comportamiento y de selección sexual. En esta contribución presentamos y comparamos las vocalizaciones de 12 especies de aves de las islas Socorro y Clarión del Archipiélago de Revillagigedo. Mostramos espectros sonoros de algunas vocalizaciones, así como una discusión de sus características y diferencias geográficas – a nivel de deme, subespecie o especie. Comparamos las vocalizaciones de algunas aves con aquéllas de sus contrapartes continentales. Documentamos algunos eventos acústicos relevantes, como son las vocalizaciones de las hembras de algunas especies, los duetos antifonales de la matraquita de Isla Socorro, o las contravocalizaciones que los cenzontles de Isla Socorro intercambian con sus vecinos al amanecer o al anochecer. Además, discutimos la aplicación de los cantos y las llamadas de algunas especies en tareas de conservación, tales como el levantamiento de censos poblacionales, la identificación de sexos o el recuento de individuos célibes o apareados. También proponemos algunas líneas que la investigación bioacústica en esta región insular pudiera tomar en el futuro.

Authors: Pineda-López Rubén , Arellano-Sanaphre Alejandro , De la Vega-Aguirre Catalina
Published: October 2022

Como resultado de muestreos mensuales durante un año en embalses de Querétaro y zonas adyacentes de estados vecinos, así como de visitas a la Sierra de Lobos en Guanajuato, presentamos nuevos registros estatales de aves acuáticas para los estados de Querétaro (Bucephala albeola, Fregata magnificens, Numenius americanus), Hidalgo (Charadrius semipalmatus, Leucophaeus atricilla, Hydroprogne caspia) y Guanajuato (Pelecanus occidentalis); además de registros notables de especies poco conocidas en zonas alejadas de las costas mexicanas. Estos registros muestran que los embalses de zonas semiáridas altas de México son más utilizados por especies poco frecuentes que lo que se ha pensado, y elevan a 70 las especies observadas en la zona semiárida de Querétaro, lo que confirma la importancia de los cuerpos de agua artificiales de esta región para la conservación de las aves acuáticas.

Published: October 2022

Las áreas arboladas urbanas son utilizadas por algunas aves invasoras en su proceso de colonización; la detección temprana de estas especies es una acción necesaria para su vigilancia y control. Utilizamos un muestreo rápido en parques urbanos, que requiere de poco tiempo de planeación y ejecución, como una forma de detección de aves que actualmente aumentan su distribución en México: Streptopelia decaocto (paloma de collar), Myiopsitta monachus (perico monje), Turdus rufopalliatus (mirlo dorso rufo) y Sturnus vulgaris (estornino pinto). Realizamos los muestreos en la mayoría de los parques de las ciudades de León de los Aldama, Guanajuato, Aguascalientes y Santiago de Querétaro. Presentamos los primeros registros de M. monachus, T. rufopalliatus y S. vulgaris para la ciudad de León de los Aldama; así como de M. monachus en la de Guanajuato. Además, en Santiago de Querétaro registramos las cuatro especies buscadas; a T. rufopalliatus en Guanajuato, y a S. vulgaris en Aguascalientes. Analizamos las variables asociadas con la presencia de las especies, así como el establecimiento de las especies en cada ciudad en relación con la proporción de parques en que se presentan. Sugerimos que este método es útil para evaluar la distribución actual de estas especies en México y proveer de conocimiento básico para futuros estudios.

The Cattle Egret (Bubulcus ibis) is an avian species native to Africa that has the ability to adapt to different habitats, environmental characteristics, and available food sources. We collected a total of 2,400 Cattle Egret excreta from four resting colonies during the months of January to March 2020, in the region of Tulancingo de Bravo, Hidalgo, Mexico; in order to identify the elements that make up the diet of the Cattle Egret. Samples were placed in 70% alcohol, and later analysed with a stereoscopic microscope. We identified a total of 1,677 items from 16 taxonomic entities that could be grouped in four categories. Arthropods were the main component in samples (51.8%), particularly insects of the order Orthoptera and Coleoptera. Other components in samples were plant material (26.6%), animal remains (13.9%), and plastic or other non-biological material (7.7%). We also report the first record of the Red-Spotted Toad (Anaxyrus punctatus) as a possible component in the diet of the Cattle Egret. The predominance of insects, particularly Orthoptera and Coleoptera, in the Cattle Egret diet in our study reflects the extent of agricultural activities in the region. Our study provides the first report on the diet of the Cattle Egret in an agricultural area or Hidalgo, Mexico, and corresponds with other studies, where variations in diet depend on the region, habitat, climate, and extent of environmental contamination.

SEMANTICS OF TRANSFORMATION OF LITERARY SPACE IN THE FINAL SCENE OF “THE CHERRY ORCHARD” BY ANTON CHEKHOV. THE ROLE OF DETAIL
Authors:   Russian State University for the Humanities, Maryakhina Elena A.
Published: October 2022

The article considers the semantics of space formed by the system of object-details and sonosphearic elements in the finale part of Anton Chekhov’s The Cherry Orchard. The theatrical version of the play created at the Moscow State Theater “Lenkom” (dir. Mark Zakharov) became a starting point for the analysis of the literary text. Detail is studied as regards the formation of motifs involved in constructing the spatial organization of the artistic world, as well as an element of the material world that constructs a space in a certain way. Such characteristics of place as narrowness, length, isolation, “verticalization” or ‘horizontalization”, as well as the properties of its boundaries create a semantic field for the world of objects and things, in which Firs finds himself at the end of the play. The contextual analysis of the world of things makes it possible to identify the role of certain characteristics in the topos of the house and estate, the semantics of their transformation, and to assess the role of details in creating the meanings associated with the ontological sphere and its change and in unfolding that meaning in the character and the reader (spectator)’s minds. The significance of the transformation of the place in the final scene makes it possible to trace the connection between the inner state of the character and the “state” of the house itself and read the play’s final scene in terms of the connection between man and place.

Authors:   Poznan University of Technology, Libertowska Andżelika
Published: October 2022

Purpose: The aim of the article is to analyze the results of research on the interdependencies between cooperation, trust, as well as norms and values, as key elements of social capital in high-tech enterprises in Wielkopolska Region. Design/methodology/approach: The analyzes carried out covered 51 enterprises belonging to advanced technology industries, including 41 small and 10 medium-sized ones. The research was conducted using the interview method, using a questionnaire and supported by the CATI technique. The obtained data were subject to further analysis and statistical inference. They consisted in determining the mutual dependencies for the three resources of social capital, i.e. trust, norms and values as well as cooperation (jointly creating the social capital of these enterprises) and their components. The relationships were determined based on the calculated Pearson's linear correlation coefficients. Findings: Based on the conducted analyzes, it is legitimate to conclude that the designated level of cooperation, norms, values and trust are closely related. For all combinations of the indicated resources, the determined Pearson's linear correlation coefficients are statistically significant with a probability of 0.05. Also, many combinations of the components of these resources are correlated with each other. Practical implications: The application dimension of the article is perceived in at least two possibilities. Firstly, for business representatives, it can be a valuable source of information on the key factors in the appreciation of social capital in a company. Secondly, on the basis of the calculated correlations, the article gives the opportunity to review the most important relationships between these components, which may also be useful from the point of view of the appreciation of social capital in the enterprise. It is also worth emphasizing the interdisciplinary nature by combining the scientific and application aspect, which can be used at the level of company management. Originality/value: This work deals with an original approach to social capital, both due to the conceptualization of the concept of social capital and its components, as well as the interrelationships between its components. It is also worth emphasizing the interdisciplinary nature of the work, combining the scientific and application aspects that can be used at the level of company management. Moreover, the methodology described in the research process may be used in enterprises operating in industries other than high-tech.
Waste management in Polish organisations participating in EMAS
Authors:   Rzeszow University of Technology, Nycz-Wróbel Jadwiga
Published: October 2022

Purpose: The purpose of this paper was to present the activities undertaken in the area of waste management by Polish enterprises participating in the EMAS system, operating in the water supply, sewage and waste management and remediation branches. Design/methodology/approach: The grounds for the assumed research method was the analysis of secondary sources in form of environmental statements. The selection of sample was targeted, the research was complete and included 19 companies participating in EMAS, dealing with water supply, sewage and waste management and remediation. Based on the analysis, groups of most frequent activities in the area of waste management have been determined and specific solutions implemented in each group have been presented. Findings: Polish enterprises mostly performed activities relating to: public educational campaigns, use of a system of measurable indicators, waste treatment or disposal and modification of waste treatment installations. It has been found, despite the fact that research has been made among organisations whose activity mainly involves positive environmental impact, that presented solutions could be implemented or inspire not only businesses with a similar profile, but also those whose operations entail producing and introducing waste to the environment. Research limitations/implications: A certain limitation of the research is the fact that information in environmental reports is not uniform, which makes it difficult to analyse. Not every organisation includes data on specific implemented activities in their environmental reports. The areas of further research may include analysis of solutions implemented by Polish manufacturing companies participating in EMAS, relating to waste or energy efficiency. Practical implications: The key input of the described research includes examples of specific actions that could be implemented by organisations dealing with various types of activity in order to prevent production of waste or reduce the volume of waste. Social implications: This paper describes exemplary solutions that could help organisations in improving their environmental performance relating to waste. Originality/value: The results of conducted research may supplement the previous research concerning the EMAS system. This paper contains guidelines and examples of specific activities that organisations could implement in the field of waste management.
Motivation of retired officers of the Polish Army to take up work after the service
Authors:   Military Academy of Land Forces in Wrocław, Rzepecka Aleksandra
Published: October 2022

Purpose: The aim of the work was to successfully define motivation and the act of motivating, but also to characterize many different kinds of the former. Based on a survey carried out among retired officers a set of data was presented, explaining the reasons for their desire to find employment after withdrawing from the army, as well as making known retirees’ opinions on their persisting willingness to keep working post-retirement. The profile of an officer of the Polish Army was also discussed. Design/methodology/approach: The research was conducted in a group of retired officers of the Polish Army in 2019-2021 using the snowball method. The study also used the method of analysis and criticism of the literature and the heuristic method, as well as the quantitative method - a questionnaire was used. The research problem was expressed in the form of a question: What factors influence the motivation of retired officers of the Polish Armed Forces to take up work after leaving the service? Findings: The termination of military service after several years of work in the Polish army may be a difficult moment for some officers, because most of their lives they worked in one organization, where there are clear and defined rules and high discipline. During their service, the officers of the Polish Armed Forces acquired valuable competences – knowledge and skills supported by experience, therefore it is important that they can still use their competence potential. It is essential that officers who will retire plan their future careers. Motivation, i.e. a set of forces and factors that are aimed at supporting an individual in certain behaviors, also plays a large role. Thanks to them, you can work towards achieving specific goals. According to the survey, retired officers take up work after leaving the service due to the desire to further use their knowledge and experience. Working in a group, contact with other people also influences the continuation of work in retirement. For some respondents, too low a retirement benefit is a factor that motivates them to look for a job. Originality/value: Results of this research should be of interest to institutions and people, who help retired officers of the Polish Armed Forces. Secondly they are also directed to officers themselves, as a support in planning their future professional career.

Authors:   Poznan University of Economics and Business, Byczyk Mateusz
Published: October 2022

Purpose: As the organization grows, attention begins to be paid to the growing potential and role of communication. Communication, which so far played mainly the role of providing information in the course of the current rapid evolution, is beginning to be noticeable in every aspect of business operations. Currently, managers must be aware that communication affects the entire organization, while it is their role to influence communication in order to obtain the best benefits. The purpose of this article is to present comments or problems that were noticed by the authors of the reviewed articles during the communication process. Design/methodology/approach: This review is based on studies conducted in case to understand communication problems, published between 2017 and 2022. Findings: The analysis highlight that the communication problems in organizations are increasingly encountered and, what is most important, almost always very easy to solve. Practical implications: In the case that almost all the publications discussed are focused on the most common problems in enterprises, it can be assumed that with a high probability such problems will appear or have already appeared in every organization. Thanks to this review, as well as a deeper analysis of the aforementioned literature, readers of this article can very quickly identify similar communication problems in their environment and its exemplary solution. Originality/value: This review emphasizes that communication should be considered on many levels since it affects both people and organizations in different respects. In addition, in this research work, it can be indicated that communication allows us to better understand human needs and act on them appropriately.
Effectiveness of Current Interventions to Alleviate Parental Distress in the NICU: A Rapid Review
Authors: Shudra Darylle , Papathanassoglou Elizabeth , Reichert Amber
Published: October 2022

Background: The birth of a premature infant and admission to the NICU is often unexpected and traumatic for families, leading to increased distress and can negatively impact parental-infant attachment. Appropriate interventions can help to lessen the negative impact of a NICU admission on families, improving parental mental health, reducing distress, enhancing parent- infant relationships, and improving the long-term physical, cognitive, emotional, and social development of the infant.

Aims: The purpose of this study is to examine and evaluate research evidence on the effectiveness of current interventions for improving parental distress in the NICU.

Methods: A rapid review was conducted utilizing a protocol based on the Virginia Commonwealth University guidance. Keyword searches were conducted on CINAHL, MEDLINE, and PsychINFO, and studies were selected according to pre-defined eligibility criteria, published between January 2015 and January 2020. The literature search included primary studies of interventions with parental stress and/or anxiety reduction as outcomes.

Results: A total of 14 articles were included, evaluating the effectiveness of 13 different interventions, including narrative writing, art therapy, structured nursing interventions, anxiety counselling, spiritual care, organizational change, music therapy, relaxation, and mindfulness techniques. With the Pexception of three, all the studies found significant results in the reduction of stress and/or anxiety levels of the subjects, with mothers having overall higher levels of stress indicated by higher stress scores on standardized measurement tools.

Conclusion: There is a need for ongoing assessment of parental distress and integration of appropriate interventions within the NICU settings. In this review, both individualized and group interventions including narrative writing, art therapy, music therapy, spiritual care, activity-based group therapy, music therapy, audio-assisted relaxation techniques, mindfulness based neurodevelopmental care, cognitive behavioral based counselling, family nurture intervention and a structured nursing intervention were shown to be effective in reducing parental stress and/or anxiety in the NICU. The small scale of the studies included in this review impact generalizability to a broader audience and emphasizes the need for larger scope, multi-center studies at an international level to build on and broaden our level of knowledge on how to better support families and reduce parental distress in the NICU.
RISK, RETURN AND INTERNATIONAL PORTFOLIO DIVERSIFICATION: K-MEANS CLUSTERING DATA
Authors: Dziuba Pavlo , Glukhova Darya , Shtogrin Kyryl
Published: October 2022

The work is devoted to the study of the international investment portfolio, its features such as risk, profitability and the level of international diversification, as well as global flows of portfolio investments. The methodology of the work is as follows. The paper develops k-means clustering model to study the patterns of global portfolio investment flows and equity markets. The model groups 30 developed and emerging stock markets according to three variables: return, risk and the level of international diversification. Thus, the main purpose of this paper is to investigate different stock markets on a global scale through an in-depth analysis of the respective market portfolios and their measures of risk, return and international diversification, as well as their interrelationships. The researcher develops and builds the model in such a way as to either confirm or refute the hypotheses put forward. The results of the study demonstrate the following results, which present opportunities for further research. The study supports the hypothesis that portfolios of investors from developed stock markets have a better level of international diversification than portfolios of investors from emerging stock markets. However, there is high within-group variation in the levels of international diversification among developed markets. There are three groups of developed markets based on the level of international diversification of investors in their respective markets: low-level markets (ca. 22%); mid-level markets (43%); and high-level markets (ca. 61%), while emerging markets are generally more heterogeneous. The hypothesis that stock markets that are domestic to investors with higher levels of international diversification have higher rates of return and lower rates of risk has not been confirmed. In general, developed stock markets are characterized by higher returns and international diversification with lower risk ratios. Nevertheless, the higher level of international diversification in developed market portfolios is not always accompanied by better stock performance. The best risk-return ratio (return – 0.46%, risk – 5.56%) is observed for markets from the cluster with an average level of international diversification. While the markets in the cluster with the highest level of international diversification have unreasonably high-risk ratios, which are not compensated by better returns. Markets in the cluster with lower levels of international diversification have unreasonably low rates of return that are not accompanied by correspondingly lower risks.

The increase in media proliferation as a result of the emergence of social media as alternative sources of news dissemination and consumption has led to many changes in journalism, such as declining gatekeeping and content scrutiny. Thus, headline construction and structuring play a crucial role in this new era of news. Like their counterparts all over the world, Nigeria’s mainstream media are not left out of this raging redefinition of news construction and distribution in a hyperbolic and propagandistic format, despite their significant contributions to democracy since its return in 1999. The rise of insecurity and the attendance of political uproars, buoyed by online misinformation through pluralistic digital media, triggers intentional or inadvertent mistakes among the hitherto respected and credible mainstream media causing the need to respond to the salient issues in the media spaces without being out of the mainstream. Using the content analysis and process tracing methods, this paper explores the influence of the current media agenda on the gatekeeping of news that is increasingly spreading misinformation via clickbait on the headlines of the mainstream media.
Correlation between latent toxoplasmosis and thyroid hormone levels in sera of schizophrenic patients
Authors: Alla Khadang Mohammed  , Sarmad Nagemaldeen Mageed
Published: October 2022

Latent toxoplasmosis is a prevalent chronic infection caused by a protozoan parasite called Toxoplasma gondii. Recent studies have shown that T. gondii may affect thyroid hormone levels and thus induce behavioral alteration. However, this correlation has been inadequately investigated. Therefore, we aimed to examine the relationship between latent toxoplasmosis and thyroid hormone levels in schizophrenic patients. For this purpose, blood samples and sociodemographic information were collected from 101 schizophrenic patients attending three psychiatric hospitals in Kurdistan region of Iraq. Anti-T. gondii-IgG antibodies and thyroid hormones levels (TSH, T3, T4) were determined in sera of all patients using ELISA technique. Anti-T. gondii-IgG antibodies were detected in sera of 40 (39.6%) out of 101 schizophrenic patients. Logistic regression analysis showed significant association between toxoplasmosis and schizophrenic patients in 50-60 age group (OR=6.177, p=0.05), and un-employed patients (OR=3.562, p=0.05). Data analysis showed non-significant difference in TSH levels between IgG seropositive and IgG seronegative group (p>0.05). On the other hand, T4 levels were significantly higher in the seropositive (10.16 ± 2.61) than seronegative group (7.01 ± 2.01), with highly significant positive correlation between IgG and T4 levels (p= 0.001). Finally, T3 levels were significantly higher in the seropositive (1.91 ± 0.5) than seronegative group (1.12 ± 0.43), with non-significant positive correlation between IgG and T3 levels (p=0.30). Owing to the fact that there was statistically significant increase in thyroid hormone levels in T. gondii seropositive patients, our results suggest that there is a significant association between toxoplasmosis and thyroid hormone levels in schizophrenic patients.

Purpose: Cypermethrin (class II) belongs to pyrethroid insecticides which have been in wide use to control various pests including moth pests of cotton, fruit and vegetable crops. This study was aimed to investigate the effects of cypermethrin on haematology of female rats and their modulation by co-administration of sodium selenite. Methodology: Four equal groups of female rats were made (n=20). Group 1 received 1 ml corn oil, Group 2 was administered 55 mg/kg/b.w of cypermethrin, Group 3 was provided with 1 ppm of sodium selenite and Group 4 was given both cypermethrin and sodium selenite. Haematological analysis of blood samples was performed employing Sesmex Kx-21 (Japan). Results: Red blood cell (RBC) count, haemoglobin concentration (Hb) and hematocrit (Hct) were significantly reduced (P<0.05) due to cypermethrin treatment which indicates that rats were suffering from anaemia. While, the rest of the hematological parameters i.e. platelet count (PLT), number of lymphocytes, white blood cell (WBC) count, platelet larger cell ratio (P-LCR), RBC distribution width (RDW), mean platelet volume (MPV), platelet distribution width (PDW), lymphocyte percentage (LYM), mean corpuscular haemoglobin concentration (MCHC), mean corpuscular haemoglobin (MCH) and mean corpuscular volume (MCV) were non-significantly affected. Selenium coadministration with cypermethrin was found to restore the levels of above-mentioned parameters to those found in control group. Conclusion: Hence, it can be concluded from this study that cypermethrin administration can cause hematological alterations in rats. Co-administration of selenium provided protection against cypermethrin toxicity to some extent.

This paper will demonstrate how a novel drill pipe conveyed casing and cement evaluation tool can change the way operators approach well integrity decisions through the well life cycle. Through field test results we will demonstrate how operators can improve efficiency, reduce rig time and personnel on board, improve safety of operations and reduce the risk of non-productive and invisible flat time through the application of what is actually not a new technology, or measurement physics but an adaptation in mode of conveyance. The new drill pipe conveyed tool can be run anytime drill pipe is utilized in the well. A radial distribution of ultrasonic transducers arranged on the circumference of a drill collar allows for full azimuthal interpretation of the casing and cement whilst rotating the drill pipe. Analysis of the acquired data allows for interpretation of caliper, thickness and an evaluation of the material in the annular space behind the casing. Additionally, the tool can provide casing collar location in real-time and has the ability to orient downhole devices such as whipstocks, perforating guns and oriented cutters. We will demonstrate through case histories the range of applications of this technology both in recorded mode and in real-time decision making to provide solutions where well integrity measurements are critical in solving problems throughout the well life cycle. Direct comparisons with wireline will demonstrate the efficacy of the technique. Real-time examples of casing collar location (CCL) show the need, especially in deviated and deep wells of running CCL on the actual operation to correctly position devices downhole and eliminate the depth discrepancies that can arise from comparison of wireline and drill pipe conveyed techniques. Examples conclusively demonstrate that the tool can be run in parallel with existing operations to minimize rig time and eliminate the need for a dedicated, standalone wireline operation. Additionally, we will discuss the advantages and disadvantages of drill pipe deployed well integrity measurements and the technology advances used to overcome some of the inherent challenges of this technique.

Measuring the state of stress in rock formations is important in many industries, with applications ranging from radioactive waste disposal and carbon storage sites to reservoir management and geomechanical modeling in the oil and gas industry. Hydraulic fracturing is a reliable technique and a direct method for measuring the magnitude of the minimum horizontal stress in the subsurface. Using wireline formation testers, this method relies on isolating an interval with inflatable packers and creating hydraulic fractures by injecting fluid into the formation and analyzing the pressure responses for multiple cycles of fracture propagation and pressure falloff to identify fracture closure and measure closure stress. There have been significant improvements in wireline formation stress testing and the performance of inflatable dual packer systems in recent years. This has resulted in development of wireline formation stress testing systems that can inject fluids for fracture initiation and propagation at differential pressures up to 6,000 psi in an 8.5-in. borehole. However, there are still technical needs for packer systems with increased pressure ratings and better compliance, as well as requirements for higher pump rates and flow control. To increase the differential pressure capability, dynamic sealing, and system compliance for stress testing in formations with higher stress conditions and breakdown pressures, a new dual packer architecture and redesigned mandrel assembly has been developed and engineered. The high-pressure packer and mandrel system that is capable of up to 10,000-psi differential pressure can be fitted to upgrade existing wireline formation stress testing systems. This system also provides better test interval isolation and compliance to reduce interval compressibility and interval volume variation to enable more accurate interval pressure measurements during hydraulic fracturing tests. In this contribution, we review the engineering and laboratory testing that was performed to validate the new wireline stress testing assembly and packer designs and the seal and retraction performance. We also describe field results and the practical application of the new system during its field application and provide a comparison with previous wireline stress testing technologies to highlight the improvements

Based on the known data on the amplitudes and phases of the main tidal waves in coastal areas of southwestern Kamchatka, their alongshore variability was analyzed. It is shown that they increase from south to north. However, it is difficult to accurately assess these variations due to the fact that coastal tide gauges, which were usually installed at the mouths of rivers, are affected by the distorting effect of bottom friction. Satellite altimetry data were used for a more accurate characterization of the spatial variability of tide magnitude. These data were obtained during the passes of the TOPEX/Poseidon satellite in 1992–2002 on the original and 2002–2005 on the orbits shifted by half the inter-track distance. The amplitudes of both diurnal and semidiurnal waves have been revealed to increase sharply in the north direction, and this increase is limited by the shelf zone of southwestern Kamchatka. Significant spatial variations in the tidal wave characteristics are the cause of strong alongshore currents in this area. Estimates obtained on the basis of calculating the difference in the tidal level at the points of various sub-satellite tracks have shown that the speed of the coastal flow can reach 1−1.3 knot. The main contribution to the formation of tidal currents is made by diurnal components.

The aim of this study is to examine the relationship between economic growth and tourism revenues in Turkey within the scope of the tourism-led growth hypothesis with the help of tests that take into account structural breaks. In this context, causality and cointegration tests based on the Fourier approach were used by considering the industrial production index, tourism revenues and real effective exchange rate data for the January 2005-December 2019 period. The results of the causality test revealed that, unlike the Granger causality test, which does not take into account the structural break, the results of the causality tests that take into account the structural break have a unidirectional causality relationship from tourism revenues to economic growth. Similarly, contrast to the Johansen test, which does not take into account the break in the cointegration analysis, the Fourier Johansen test detected the existence of a long-term relationship between economic growth, tourism revenues and the real exchange rate. In addition, the long-term cointegration estimation showed that tourism revenues have a positive and statistically significant effect on economic growth.
