The Competitiveness of Qatari Tourism: A Comparative and SWOT Analysis
Authors: Yap Ghialy , Saha Shrabani , Alsowaidi Saif S. 
Published: July 2022

Purpose- Qatar has placed its tourism sector as one of the main strategies of economic diversification to achieve sustainable tourism goal. The country aims to develop diverse tourism products, ranging from cultural, urban, and nature tourism to education. The government has invested a huge amount in designing and building tourism infrastructures such as the eight new stadiums to host the 2022 World Cup, the national museum, Museum of Islamic Art, Katara Cultural Village, Souq Waqif, and many resorts and high end hotels. Given these significant tourism investments, it is unquestionable that the country reaps commensurate long-term benefits in terms of growth of its tourism sector and possible ripple effects in other sectors of the economy. Hence, this study reconnoitres the viability of positioning Qatar’s tourism sector as being pivotal to its economic-diversification strategy by comparing its tourism competitiveness with its strong competitors, namely the United Arab Emirates, Egypt, Saudi Arabia and Turkey. Methodology- To examine this, the study employs secondary data, questionnaire surveys as well as SWOT analysis to identify the strengths and weaknesses of Qatar relative to the competing destinations. Findings- The findings reveal that Qatar is not price competitive with the nearby countries. Furthermore, the competing nations, in general, have longer and deeper expertise in tourism, and invested more resources than Qatar in developing their tourism sectors. However, Qatar performed the best for its health and financial systems, compared to its competitors, based on scheme of the Global Competitiveness Rankings. In order to increase its tourism, the country should focus more on developing the highest quality of health tourism products and targeting on wealthy tourists who can afford to buy a property and live in Qatar as second-home residents. Originality/value- This paper investigates the tourism competitiveness of Qatar in comparison of its neighbouring destinations with respect to the goals set up by the Qatari government. Based upon the analysis, it can be concluded that Qatar has loss its price competitiveness to its neighbouring countries. Furthermore, the study provides a comprehensive examination of Qatar and its competitors using all indices provided by the Travel and Tourism Competitiveness reports, and conduct strengths and weaknesses analysis based on these indicators.
Building the skill of happiness: WeChat’s role in the promotion of mental health in China
Authors: Bram Barclay 
Published: July 2022

Abstract
China is in the midst of a “psy-boom” as the use of psychological services and interest in psychology and psychologically informed personal development tools are seeing a meteoric rise. One of the key drivers of this trend has been the innovative use of social media tools like WeChat by psychological service providers to both attract consumers and deliver products. This paper argues that online psychological service provision via WeChat constitutes a very literal “technology of the self” in the way that the content published explicitly tells consumers that a better, healthier and happier self is within reach. For a fee these companies help provide people with psychological toolkits that they use to shape their understanding of the ways they can heal themselves and others.

Abstract
Medicinal plants contain phytochemical components of pharmaceutical importance, and Trema orientalis MeOH extracts are believed to have potential antioxidant and cytotoxic properties. This investigation explores the phenolic, antioxidant, and anticancer property of the methanol extracts of aerial parts of T. orientalis. The total polyphenol content (TPC) and the total flavonoid contents (TFC) were determined following standard methods. In vitro antioxidant property was assessed by 1,1-diphenyl-2-picrylhydrazyl (DPPH) and 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays. Cytotoxicity experiments were performed against eight cell lines and one fibroblast cell using the methylthiazolyldiphenyl-tetrazolium bromide assay. The antimicrobial activity assay was performed using the agar-diffusion method. Individual phenolic acids identified by GC/MS were examined in silico to estimate their drug likeness based on their structures. TPC and TFC were the highest in the leaf extract, with the strongest radical scavenging activity against ABTS (84.43%) and DPPH (79.60%) radicals. The highest cytotoxicity activity was exhibited by leaf (IC50 = 2.256 ± 0.85 μg/mL) and twig (2.704 ± 1.31 μg/mL) extracts against the HCT116 cell line, followed by bark (3.653 ± 0.05 μg/mL) and leaf (3.725 ± 0.30 μg/mL) extracts against the HT29 cell line. Clonogenicity resulted in a clear decrease of colony formation by HCT116 cells, suggesting a dose-dependent mode. In silico investigation suggested that phenolic acids detected have non-drug-like properties. Extracts showed antimicrobial inactivity.

Аннотация
Вопреки общепринятым представлениям о том, что испанские писатели не уделяли особого внимания России из-за ее удаленности, в данной статье предпринята попытка доказать наличие этого внимания и описать его своеобразие. На самом деле испанцы проявляли живой интерес к культуре России, страны, расположенной на противоположном конце «великой европейской оси», как отметил испанский философ и эссеист Хосе Ортега-и-Гассет. В статье на основе изучения образа России в испанской литературе показано, что образ России часто служил испанским писателям средством самопознания, и русская тема подчас превращалась в испанскую.
Compact low-pass filter (LPF) with wide harmonic suppression using interdigital capacitor
Authors: Mandal Arpita , Moyra Tamasi 
Published: July 2022

Abstract
In this article, a compact microstrip low-pass filter (LPF) with low in-band insertion loss and a wide attenuation band is recommended. The structure is modeled using two rectangular-shaped open resonators (ORs) loaded with multiple sections of the interdigital capacitor. The proposed LPF has a cut-off frequency of 1.5 GHz, a passband insertion loss of 0.35 dB, and an electrical circuit size of 0.02 λ
g
2. In the ground plane, two dissimilar defected ground structures (DGSs) are introduced to generate additional attenuation poles for enriching the stopband performance of the LPF. The harmonics suppression is achieved up to 15 GHz with tenth harmonic suppression and relative stopband rejection of almost 165%. The EM simulated results show a well-matched behavior with the experimental ones. The proposed LPF can be used for global positioning systems (1500 MHz), telecommunications (1600 MHz), and audio broadcasting (1400 MHz) applications.

Abstract
To effectively control the flow and combustion of pulverised coal in down-fired boilers and improve their thermal efficiency while ensuring low NO
x
emissions, on arch secondary air (OASA) combustion technology and a smoke-tracing analysis were proposed. The aerodynamic characteristics of a 300-MWe Foster Wheeler (FW) down-fired boiler with the OASA ratios (R
OASA) of 0%, 10%, 20%, and 30%, the flow trajectories and mixing characteristics of OASA, and fuel-rich coal/air flow (FRA) and fuel-lean coal/air flow (FLA) were studied experimentally. For the R
OASA of <10%, FRA and FLA flow to furnace centre soon after they are injected into the furnace. OASA and FLA may mix with FRA before ignition. For the R
OASA of 20% or higher, FRA and FLA flow to the near-wall area soon after being injected into the furnace. FRA mixes with OASA after ignition. With the increase in R
OASA, the mixing distance between OASA and FRA increases first and then decreases. The penetration depth of coal/air flow and furnace airflow fullness increases. For the R
OASA of 30%, the dimensionless penetration depth of coal/air flow can exceed 0.7. Furnace dimensionless airflow fullness at all the dimensionless heights can exceed 0.6. In real operation, the recommended R
OASA is between 20 and 30%.
Reinterpretation of the Geldart A powder classification based on Eulerian–Eulerian CFD simulation
Authors: Kannan Janani , Sande Priya C. 
Published: July 2022

Abstract
Geldart classified powders into four categories and assigned each category its own unique characteristic. Geldart A particles, being easily aeratable, show a unique feature of ‘Homogenous expansion’ before bubbling. In this work, an additional feature for the Geldart chart is proposed which adds significant utility for the processing of Geldart A particles. CFD was used to characterize the entire Geldart A region of the Geldart chart based on detailed fluidization behavior. For this, Eulerian–Eulerian Two-fluid model (TFM) simulations were conducted for 25 particle systems across the entire span of the Geldart A region. The simulations (Solid volume fraction (SVF) contours) of bed evolution, taken before the appearance of multiple bubbles, were analyzed in detail. The particle systems were then sub-categorized into Red (5% average bed expansion), Orange (12.5% average bed expansion), and Green (30% average bed expansion) sub-types. The sub-types were plotted on Geldart chart, and for the first time a continuum heat map was generated, from which the ‘level of fluidizability’ of all Geldart A powders can be conveniently gaged. The map can be used for a more informed choice of powder for various industrial applications. Also, the A/B boundary proposed by Verloop was found to be a better fit for our proposed continuum when compared to the original Geldart A/B boundary. The 2D Simulation results performed in this work, found adequate validation against experimental findings in literature. Further, fine mesh 2D simulation results compared well with 3D simulations for dense bed, and were thereby deemed adequate for revealing dense bed behavior before onset of multiple bubbles.

Abstract
The historically underrepresented Pacific Colombian Coast is known for its social injustice and poverty. However, in this adverse environment, a group of artists called School and Workshop Watercolorists of San Cipriano, created in the decade of 1990s, decided to use art as the means to express both their individual and collective concerns. The artists are watercolorists, photographers, painters, and sculptors who tell their stories through their work. The pieces of four San Cipriano artists have been displayed in Buenaventura’s local venues and at the National Museum of Colombia. In addition, these artists are helping in the assemblage of the permanent museum’s hall, Strength, Faith, and Substance, which is a joint effort of the grassroots artists, anthropologists, and archaeologists, to display Colombian spirituality. The following is a transcription of an Explorers event with the watercolorists and the museum professionals involved in the hall’s display.

Published: July 2022

Abstract
Early detection is crucial for optimal treatment and prognosis of cancer. New approaches for pan-cancer screening comprise the comprehensive characterization of circulating tumor DNA (ctDNA) in plasma by next generation sequencing and molecular profiling of mutations and methylation patterns, as well as fragmentation analysis. These promise the accurate detection and localization of multiple cancers in early disease stages. However, studies with real screening populations have to show their clinical utility and practicability.

Authors: López Muñoz Irasema 
Published: July 2022

Currently, the use of information and communication technologies and, especially, the Internet, favor a greater exercise of the rights of children and adolescents, such as freedom of expression and information; however, given this present panorama, it is imperative that not only the benefits that the use of information technologies brings us be observed, but also the dangers that are implicit in the use of these must be considered. For this reason, the present article has the general objective of analyzing the best interests of the child, as a procedural standard in the protection of infants and adolescents against the use of information technologies to identify some of their main risks, and the measures of protection in the Mexican legal system. The main conclusion of this study emphasizes the inclusion of general legislative, administrative, social and educational measures, translated into technological solutions for prevention and protection, where the assistance and support of those who exercise parental authority, guardianship and custody is essential in the use that children and adolescents make of said information technologies.

Published: July 2022

Objectives/Background: The aim of this study was to investigate nutritional habits, biochemical markers and the allele and genotype frequencies of GCK rs4607517 -30G>A polymorphism of patients with Type 2 Diabetes Mellitus (T2DM).Methods: The study was conducted with 200 T2DM patients and 100 controls. The analysis of GCK Gene rs4607517 -30G>A polymorphism was performed by Real-Time PCR method. The Attitude Scale for Healthy Nutrition was applied to the intervention group. Additionally, the sociodemographic data of the patients were collected, anthropometric measurements were performed and their biochemical markers were examined.Results: The mean duration of diabetes of the patients was 7.94±5.81 years, the mean age 55.88±12.23 years, the mean BMI 30.14±5.91 kg/m2, and the mean HbA1c value was 7.74±1.97. There was no difference between allele and genotype frequencies of two groups (p>0.05). The anthropometric and biochemical values of the patients with different genotype was similar (p>0,05). Furthermore, as the HbA1c values of the patients increased, the Malnutrition score was found to increase, and there was a statistically significant found between the groups (p=0.012). Conclusion: Although there are studies related to the effect of rs4607517 polymorphism in the GCK gene on the development of T2DM, the fact that the frequency of polymorphism of the patient group in our study was similar to the control group makes it necessary for the variant to be screened in larger patient populations. The majority of patients with T2DM were found to have high levels of HbA1c, LDL cholesterol, and triglycerides, inadequate level of nutrition knowledge and were obese.

Published: July 2022

OBJECTIVES
Social determinants of health have been demonstrated to be important drivers of health outcomes and disparities. Screening for social needs has been routinely performed and shown to be beneficial in ambulatory settings, but little is known regarding parent perspectives on screening during pediatric hospitalizations. This study sought to determine parental attitudes surrounding inpatient screening and screening process preferences in the hospital setting.

METHODS
We conducted 17 semistructured interviews with English- and Spanish-speaking parents of hospitalized children at 1 tertiary and 2 community hospitals between July 2020 and February 2021, with questions probing opinions and experiences with social needs screening, comfort level with discussing social needs with hospital providers, and screening process preferences in the hospital setting. Interviews were recorded, professionally transcribed, and analyzed thematically.

RESULTS
Participants were median age 32 years, with majority female and English-speaking, and nearly one-half with children admitted to a community hospital. Emergent themes included (1) importance of screening for social needs across multiple health care settings, (2) hospitals viewed as capable systems to respond to social needs, (3) most parents comfortable discussing social needs with inpatient providers, (4) appreciation for providers expressing caring and desire to help during inpatient screening, and (5) importance of a family-centered approach to inpatient screening.

CONCLUSIONS
Parents reported positive perceptions regarding pediatric inpatient social needs screening importance and hospitals’ ability to address social needs and identified multiple screening process preferences for the hospital setting that can inform the development of family-centered inpatient social needs screening strategies.

Published: July 2022

Introducción. La actividad agropecuaria es usuaria y productora de energía, puede evaluarse mediante el análisis energético, que también relaciona conceptos de física, bioquímica y biología. Objetivos. Evaluar desde un enfoque energético expandido, distintos modelos comerciales de producción primaria de leche. Materiales y métodos. Se trabajó con datos retrospectivos de nueve establecimientos lecheros de la Región Pampeana Argentina, entre julio de 2014 a junio de 2015. Se calcularon cuatro indicadores: egreso energético (EE), ingreso energético (IE), eficiencia energética (EE/IE) y anergía (A). Resultados. Los mayores EE se basaron en productividad primaria neta, en condiciones de alta suplementación. El IE promedió fue 239,9 GJ/ha/año, rango en que se alinearon los sistemas con carga animal media. El agua (67 %) fue la principal aportante. La eficiencia (EE/IE) presentó marcada variabilidad, basada en los IE; aunque la biomasa vegetal fue la mayor causa de fluctuación de los EE, ya que los aportes de leche y carne no difirieron entre sistemas. El stock (almacenamiento) energético remanente no se utilizó dentro del sistema, ni contribuyó con el mismo mediante su exportación, por lo que se definió como una fracción sin utilidad práctica (A). Conclusiones. El análisis energético fue una herramienta válida para evaluar la sustentabilidad de los sistemas, se aplicó en modelos de producción con diferentes estrategias de intensificación. Al incluir la biomasa vegetal, los mayores egresos energéticos (EE) se apreciaron en modelos de alta suplementación, pero en el subsistema lechero tomado de manera individual, se asoció carga animal con mayores EE (por incremento de productividad) y mayores ingresos energéticos (IE), debido al incremento en el agua consumida.

AbstractRecently infectious diseases and increasing microbial drug-resistant have caused many humorless health problems. To fill knowledge gaps and guide strategies at all levels for antimicrobials which represent a challenge and an urgent need. For these reasons, our target is developing a new effective antimicrobial drug with extended action time, multi-antimicrobial agents, low toxicity, and safe strategies. Metal–organic frameworks are promising materials for antimicrobial agents. Herein, a novel affordable Fe(III)-MOF was simply prepared via a reflux method. FE-SEM images showed an octahedral structure with sharp edges with high crystallinity and purity of Fe(III)-MOF. Under optimum conditions, the Fe(III)-MOF showed excellent antimicrobial efficiency against ± bacteria, fungus, and yeast with an inhibition zone ranging between 40–46 and 22–24 mm at a concentration of 50 and 25 μg/mL Fe(III)-MOF, respectively. As well, the mechanism of interaction is also well studied. The results open the door for the use of prepared materials as an effective and efficient antimicrobial agent.Graphical abstract
Local Self-government in the System of Civil Society Institutions
Authors: Nikitina Elena E. 
Published: July 2022

Changes in public relations and a high level of civic engagement have led to the constitutional amendment and adoption of such categories as civil society and institutions of civil society. An important result of constitutional modernization was the normative consolidation in the text of the Constitution of the Russian Federation of the main forms of interaction between civil society institutions and public authorities. For the implementation of the constitutional provisions, it is necessary to develop theoretical ideas concerning the activities of the structural elements of modern society on their interrelations with public authorities.
The legal characteristics of a civil society institution are studied in the context of local self-government. It is opined that local self-government is not even remotely qualified to be regarded an institution of civil society because it lacks the attributes of independence and autonomy of activity. In accordance with the legislation of the Russian Federation, a significant part of the activities of local self-government bodies, including their formation, takes place in the public sphere. Only certain elements of their activities in particular, the forms of direct democracy can be attributed to the sphere of civil society. It is suggested that local self-government be considered from the general law view as a form of interaction between civil society institutions and the public authorities.
Special attention is paid to the relationship between local self-government and civil society. An analysis of the current regulations on the interaction between civil society institutions and local self-government bodies leads to the conclusion that the existing legislation does not fully provide for the implementation of various forms of direct participation of citizens and their associations in the local self-government affairs. Therefore, it is necessary to improve legislation in order to increase the effectiveness of the interactions between local self-government bodies and civil society institutions.
