The impact of designated market-makers on liquidity in frontier markets
Authors: Matek Petar-Pierre , Galić Maša
Published: July 2024

Many exchanges around the globe have implemented market-making schemes inan attempt to mitigate liquidity risk and enhance trading volume. This researchexamines the impact of designated market makers on stock liquidity in frontiermarkets, specifically measured by bid-ask spreads and trading turnover. Using adifference-in-differences analysis, we studied 19 stocks that introduced designatedmarket makers at the Zagreb Stock Exchange and Ljubljana Stock Exchangebetween May 2010 and January 2022. To the best of our knowledge, this is the firststudy investigating the impact of market makers in these specific markets and onlythe second in frontier markets overall. As expected, we find a significant reductionin bid-ask spreads for most stocks following the introduction of market makers.However, unlike findings of studies conducted in more developed markets, ourresults for turnover are not conclusive, suggesting that market makers alone maynot be sufficient to overcome structural impediments to market liquidity in frontiermarkets, such as lack of free float and the dominance of large investors with long-term investment horizons.
Infectious Diseases and Their Role in Neuroimmune Disease
Authors: Melamed Isaac
Published: July 2024

Recent findings suggest a relationship between a post-infectious immune response and neurologic changes. These changes, manifesting as various neurological symptoms, including memory issues and cognitive alterations, may be linked to a form of post-infectious autoimmunity. We have coined the term “Alzheimer’s of the Immune System,” or AIS, to describe this syndrome and various immune partners that may play a role in this immune dysfunction have been identified. Here, we will discuss several clinical presentations that feed into the hypothesis of infectious-immune axis and its mechanism of action. We propose that these disorders fall under the umbrella of AIS and discuss the role of immuno therapy in their management. First, we consider pediatric acute-onset neuropsychiatric syndrome (PANS), a broad diagnostic criterion created to describe children with severe, sudden onset of neuropsychiatric changes. Research exploring the link between immune dysregulation in PANS and its amelioration with intravenous immunoglobulin treatment strongly suggests the association of PANS with a pro-inflammatory state. Next, we delve into autism spectrum disorder (ASD), characterizing it as a neuroimmune disorder. ASD marked by communication and social skill deficits, as well as repetitive and stereotypical behaviors, is characterized by related but distinct profiles of immune dysregulation, inflammation, and endogenous autoantibodies that persist within the affected individual. Further definition of the role of immune dysregulation in ASD thus necessitates a deeper understanding of the interaction between both the mother’s and child’s immune systems, and their potential role in diagnosis and treatment. Lastly, we discuss post-viral fatigue syndrome in patients who have recovered from SARS-CoV-2 infection as another example of neuroimmune condition recently added to the growing list. Further research is needed to validate our hypothesis of AIS, including large scale randomized control trials of different immuno therapies. By unravelling the infectious-immune axis and its mechanism of action, we equip physicians with valuable tools for identifying optimal forms of treatment and management for these conditions.
Association of PSEN1 Mutation with Dementia with Lewy Bodies without Features of Alzheimer’s Disease
Authors: Ayyalu Tanesh , Fredrick Jason , Singh Neeraj
Published: July 2024

Dementia with Lewy bodies affects 0.4% of people over the age of 65 each year, making it the second most common neurodegenerative form of dementia following Alzheimer’s disease. It is more commonly diagnosed over the age of 50, and in men more than in women. As a synucleinopathy, in which alpha-synuclein inclusions accumulate in neurons, dementia with Lewy bodies shares many clinical features with idiopathic Parkinson’s disease, including bradykinesia, visual hallucinations, and cognitive decline. Neuroimaging in dementia with Lewy bodies reveals occipital and parietal atrophy and hypometabolism. Some cases of dementia with Lewy bodies and idiopathic Parkinson’s disease have been shown to be associated with genetic mutations, such as in the GBA gene. In this case report, we present a unique case of a young man who started showing clinical features of dementia with Lewy bodies at the age of 43, with further confirmation of the diagnosis in neuroimaging studies. However, his genetic test results revealed the presence of a PSEN1 mutation, which has been described with Alzheimer’s disease, even though he did not show typical clinical or neuroimaging findings that matched with Alzheimer’s disease. This report reveals a potential unique association of the PSEN1 mutation with early-onset dementia with Lewy bodies, indicating that we may have an incomplete understanding of the function of such genes in cognitive development, as well as the phenotypic presentations of dementia with Lewy bodies, idiopathic Parkinson’s disease, and Alzheimer’s disease.
Current Concepts of Leukemic Stem Cells: Origin, Characteristics, and its Clinical Implications in Acute Myeloid Leukemia
Authors: Sivakumar Visaali , Ravi Soundarya , Manivannan Prabhu
Published: July 2024

Despite significant advancements in therapy, patients diagnosed with acute myeloid leukemia (AML) continue to face poor outcomes, often experiencing relapses even after achieving initial complete remission. The occurrence of relapse is attributed to the inability of conventional treatment to eliminate a specific subset of cells within the bone marrow known as leukemic stem cells (LSCs). These specialized cells exhibit self-renewal capacity and have the ability to proliferate and differentiate into leukemic blasts. The accumulation of multiple genetic mutations in LSCs makes them resistant to standard chemotherapy. Several studies have been conducted to identify the phenotypic characteristics and genetic signatures of LSCs, with the aim of differentiating them from normal hematopoietic stem cells (HSCs). Understanding the role of LSCs in AML treatment resistance has paved the way for the development of targeted and more precise treatments, especially for relapsed AML patients, without affecting the healthy HSCs. This review elaborates on the origin, phenotypic and genotypic characteristics of LSCs, and their role in the biology of AML, with a brief note on therapies targeting LSCs.

Anesthetic management in orthopaedic surgery for rheumatic patients
Authors: Shetti Akshaya N
Published: July 2024

Patients with rheumatic diseases frequently require orthopaedic surgeries due to progressive joint damage and deformities. These patients pose unique challenges for anesthesiologists due to systemic involvement, altered anatomy, and chronic pain management needs. This review explores optimal anesthetic strategies to improve surgical outcomes and enhance patient safety in this vulnerable population. Preoperative assessment is crucial for identifying systemic manifestations of rheumatic diseases, including cardiovascular, respiratory, and renal involvement, which can significantly impact anesthetic management. A thorough evaluation helps tailor the anesthetic plan to individual patient needs, ensuring better perioperative care.

Regional anesthesia, particularly neuraxial blocks and peripheral nerve blocks, offers significant benefits over general anesthesia in this population. These techniques can reduce postoperative pain, enhance recovery times, and decrease opioid consumption. However, the presence of spinal deformities and anticoagulation therapy in these patients requires careful consideration and meticulous planning. Multimodal analgesia, combining regional techniques with systemic medications, is recommended to manage chronic pain and minimize opioid use postoperatively. Effective pain management strategies are essential for improving postoperative outcomes and patient satisfaction.
Congenital cervical teratoma
Authors: Sumarlin Sofi , Suhandr Wiwin
Published: July 2024

: Teratoma, originating from the Greek word "teras" meaning "monster," reflects its diverse tissue composition, often containing ectodermal, mesodermal, and endodermal tissues. These embryonic germ layers contribute to the rarity of teratomas in the neck, though they are more commonly found in the sacrococcygeal area. Notably, teratomas occurring in the cervical region can lead to life-threatening symptoms due to their mass effect.

: A 26-year-old multiparous woman highlighted the challenges of managing cervical teratomas. During her 38th week of gestation, an ultrasound revealed a tumour on the foetus's neck, measuring 5.2 x 4.7 cm with doppler, neovascularization, and solid parts suspected to be a teratoma. The patient, despite no prior illness, had not taken prescribed vitamins during pregnancy. She underwent a caesarean section, delivering a baby girl weighing 3100 grams with an Apgar score of 8, who was found to have a solid mass in the posterior neck. The baby underwent surgery three days later, where 200-gram mass was removed and identified as a mature teratoma through anatomical pathology examination. The successful surgery allowed the mother and baby to return home in good condition.

: Teratomas emphasized their diverse nature, with cervical teratomas mostly affecting females and originating from early aberrant germ cells. These tumours, often neuroepithelial, rarely become malignant. Diagnosis involves prenatal ultrasonography, aiding in intervention planning, while postnatal imaging guides surgical approaches.

: Congenital teratomas pose challenges in prenatal diagnosis and management, requiring a multidisciplinary approach. Early detection through antenatal imaging, surgical excision, and meticulous follow-up are crucial for optimal outcomes, emphasizing the importance of comprehensive care and collaboration across medical specialties.

Authors: Cofferri Fernanda Fátima , Novello Tanise Paula
Published: July 2024

A educação a distância é uma modalidade de ensino que tem se consolidado cada vez mais nos diferentes níveis. Assim, problematizar e compreender como acontecem os processos pedagógicos na Educação a Distância (EaD) é emergente. Nesse sentido, o presente artigo apresenta um recorte do amplo escopo que compõem essa modalidade de ensino, focando no feedback como um dispositivo para a permanência dos estudantes. O objetivo é analisar as perspectivas de tutores e professores acerca do feedback como elemento determinante para a permanência estudantil na EaD. Para tanto, a produção dos registros aconteceu durante um curso de formação de tutores de uma universidade federal brasileira em que tutores a distância registraram perspectivas e entendimentos acerca do feedback. Os registros produzidos foram analisados numa perspectiva qualitativa, a partir da Análise de Conteúdo (Bardin, 2011), sendo a discussão reflexiva-teórica organizada em duas seções, uma delas abordou os desafios e potencialidades do feedback, e a outra seção o processo de orientação do professor ao tutor na elaboração de feedback. Por fim, o estudo aponta que, no processo de mediação pedagógica, as ações de professores e tutores são complementares e precisam ser articuladas, especialmente no processo de elaboração do feedback, no alinhamento de critérios avaliativos, objetivos pedagógicos, bem como, as questões que perpassam a disciplina. Tais elementos impactam na interação e no processo formativo dos estudantes, tutores e professores. Assim, o feedback se configura em um elemento determinante para a qualidade e permanência na educação a distância.

Published: July 2024

Introduction. The article examines the social transformation of state-confessional relations, its historical aspect, positive and negative trends of their evolution in the conditions of the formation of modern Russian society. The object of the study was the socio-philosophical aspects of some provisions of the economic model based on the principles of Islam as one of the traditional denominations of the Russian Federation. Theoretical analysis. The theoretical foundations of this issue in the paradigm of classical Muslim thought are given, as well as examples of their application in the modern socio-economic field of Russian regions. The philosophical justifications of the considered models of social relationships are analyzed from the standpoint of Islamic theology. Conclusion. The result of this work is the conclusion that the use of the potential and developments based on the socio-philosophical aspect of Islamic theology can serve as a positive experience of the inclusion of Islamic models in the all-Russian socio-economic field. This vector of development is designed to make progress in the spheres of life of the Russian society. And at the same time, the integration of the denominational aspect into the paradigm of socio-economic development of Russia has a special role to play.
Coping methods as a new paradigm for the processes of influencing the behavior and personal traits of schoolchildren
Authors: Saveleva Olga E. ,   Smolensk State University
Published: July 2024

Introduction. Many educational systems recognize the importance of building a skill of conflict-free communication in the younger generation, which is based on tolerance or the ability to accept others without judging. Statistics indicate the presence of a large number of theoretical works on the development of conflict-free communication skills. However, psychologists record an increase in aggression and conflict in Russian society. According to the author, the problem is not in the content-related component of personality formation, but in the methods used in modern schools. Theoretical analysis. The comparative analysis of methods of molding the behavior of schoolchildren revealed the skewed nature of those ones that are used in Russian schools. All of them belong to the “character-building” paradigm. Meanwhile, foreign schools use not only character-building methods to correct behavior, but also teaching methods, for example, they teach coping strategies (breathing, meditative techniques, etc.). Conclusion. The author suggests that the general pedagogical paradigm of personality formation should include not only methods of character building, but also methods of coping (for example, with stress and other negative emotions). It is proposed to classify coping methods into behavioral, auto-training and communication-related ones based on the mechanism and agent of influence.
Impact of Old-Aged Spryce Forests on the Carbon Balance of the Conyferous Forest Stand of the Valday Region
Authors: Yuzbekov Ahmed K. , Kumanyaev Anton S.
Published: July 2024

Monitoring the photosynthesis- and respiration-related characteristics of the old-aged forests of the Valday Region is of paramount importance since it is imperative that the role of all factors contributing to their carbon balance should be evaluated. This work presents data on seasonal dynamics of midday carbon-dioxide exchange and photosynthetic productivity of the Norway spruce (Picea abies L.) in May - October 2018-2020. It was established that the main factors determining the CO2 assimilation rate of the spruce are the air temperature and illumination. The average annual photosynthesis intensity level was more than two times higher than the light-dependent respiration level. Significant interseasonal changes in spruce photosynthetic productivity were revealed: the maximum and minimum photosynthetic productivity was detected in June-July and October, respectively. The interannual changes were related to the weather conditions and to the state of the forest stand in the tested area. The total carbon dioxide uptake by spruce needles in 2018, 2019, and 2020 was 3.3, 2.13, and 1.15 ton of CO2∙ha-1∙year-1. The average value of net primary production (0.37 ton of C∙ha-1∙year-1) and the positive carbon dioxide balance of the Norway spruce testify to a considerable influence of old-aged spruce forests on the carbon balance of the forest cenoses of the Valday Region.

Authors: Tsepina Natalia I. , Kolesnikov Sergey I. , Minnikova Tatiana V. , Ruseva Anna S. , Trufanov Dmitry A.
Published: July 2024

The effect of silver nanoparticles (AgNPs) in concentrations was evaluated 0.1; 0.5; 1; 5; 10; 50 and 100 mg/kg for the germination and root length of ordinary black earth radish 30 days after contamination. It was found that the degree of ecotoxic effect of AgNPs on the germination and length of radish roots is directly dependent on their dose in the soil. The content of AgNPs 1, 5, 10, 50, 100 mg/kg in ordinary chernozem caused a decrease in the germination of radish by 11, 13, 15, 18 and 38 % compared with the values in uncontaminated soil. Doses of AgNPs 0.5, 1, 5, 10, 50 and 100 mg/kg inhibited the length of radish roots by 19, 20, 25, 30, 37 and 43 % compared with the values obtained in uncontaminated soil. The radish root length index showed the greatest sensitivity to soil contamination by AgNPs compared to the germination index. The obtained results on the assessment of phytotoxicity of soils contaminated with AgNPs can be used for diagnostics and as an indicator of the ecological state of soils.

Authors: Adzhiev Anatoly Kh. , Kupovykh Gennady V. , Yurchenko Natalya V. , Kerefova Zalina M.
Published: July 2024

The work examines the anomalous thunderstorm process that occurred on the territory of the Rostov region on June 27, 2023. This thunderstorm process was observed in other regions of the North Caucasus, but the greatest intensity of thunderstorm activity was observed in the territory of the Rostov region, where the thunderstorm lasted more than a day. The analysis of thunderstorm activity was carried out using data from the lightning direction network of the Federal State Budgetary Institution "High Mountain Geophysical Institute". During the day, about 60,000 lightning strikes were recorded in this territory, of which 7,635 were ground strikes. Of the registered 7635 ground-based lightning discharges in the Rostov region, negative lightning amounted to 6625, and positive lightning – 1010. The share of negative lightning discharges from the total number of ground-based lightning discharges in the specified territory was 87 %. The largest number of negative lightning (more than 70 %) had values up to 20 kA. More than 50 % of positive lightning discharges had values from 21 to 40 kA. The average value of the negative polarity currents was -19.19 kA, and the positive polarity was +39.7 kA. Such a large-scale thunderstorm process is a consequence of regional climate change. When carrying out lightning protection measures for facilities in the Rostov region, it is recommended to take into account abnormal values of thunderstorm activity.

Authors: Kondrat Oleksandr R. ,   Ivano-Frankivsk National Technical University of Oil and Gas, Shmuilin Taras V. ,   Ivano-Frankivsk National Technical University of Oil and Gas
Published: July 2024

The existing problems of production, collection and preparation of high-viscosity oils need to be solved by further research and search for effective technologies. The oil of the Kokhanivske field is unique among the fields of Prykarpattia region, which is characterized by a high density of ≈1000 kg/m3, a significant content of asphaltenes, resins up to (45–60% by weight) and sulphur (7%), which is most suitable for the production of the highest quality bitumen. According to the physico-chemical characteristics and composition of the oil of the Kokhanivske field, an analysis of the conformity of this oil to the bituminous group according to the international classification was carried out. It is emphasized that this oil can be an analogue of the raw material from which high-quality bitumen of the Swedish company Nynas are produced. In connection with the above-mentioned physical and chemical properties of the oil from the Kokhanivske field (high density, viscosity asphaltene and resin content, etc.), significant complications arise during its collection and preparation. In order to solve the problem of preparing this type of oil, a technological solution for its preparation with a wave field of different intensity is proposed. In accordance with this technological solution, a laboratory setup was developed to study the effect of a wave field of different intensity on high-viscosity oil of the Kokhanivske field based on the Yutkin effect.

The facial skin of the study subjects was divided, with the experimental sample on the right side and the control sample on the left; the all-in-one cream was applied twice a day, in the morning and the evening, respectively, for eight weeks. During the experiment, the research subjects were not made aware of the components of the sample. The research results are as follows.
The all-in-one cream containing sucrulfate had the effect of improving skin roughness, shrinking pores, reducing pigmentation, maintaining moisture content, increasing elasticity, and reducing wrinkles. It is expected that sucralfate will be commercialized as a stabilizing material in the cosmetic industry in the future as it has proven its effectiveness in improving facial skin.
Proposal for Hairstyles Inspired by Natural Images
Authors: Kang Yeo-Jin , Kim So-Hyeon ,   The Korean Society of Beauty and Art
Published: July 2024

In October 2022, the National Human Rights Commission of Korea confirmed that school regulations regarding hair length infringe upon students’ rights. Back in 1982, the Ministry of Education introduced ‘Hairdo Freedom’. Since then, the regulations have been adjusted in response to social changes. Nonetheless, witnessing such regulations being lifted remains exceptional. In fact, there have been various discussions regarding regulations for employees as well as students. These changes indicate that our society has transitioned from an era of ‘respect for human rights’ to an era of ‘respect for individuality’. The respect for individuality forms the foundation for the ground for the growth of beauty industry. This necessitates a high level of professionalism in each field because consumers seek out experts who can distinguish themselves with unique styling skills and expertise. Consequently, beauty corporations have strived to introduce new styles on a quarterly or annual basis, while small businesses have also been releasing their own styles. In this new era of information and communications technology (ICT), consumers access information about these experts through their mobile devices. Therefore, it is the right time to develop new and creative ideas to effectively respond to such changes. Throughout the extensive history of art, nature has served as a focal point for aesthetic inspiration. In fact, it holds great symbolic significance as an art motif in design because it offers a wealth of unique images that can inspire people to create imaginative artworks. These days, the trend-sensitive beauty industry has experienced an increase in demand for distinctive and creative designs. Given these circumstances, it seems that nature could serve as a creative and distinctive source of inspiration. Therefore, this study proposes practical hairstyles inspired by such natural images.

Cholnoky László (1879−1929) egész élete során szoros kapcsolatban állt olyan zsidó folyóiratokkal, mint az Egyenlőség, a Múlt és Jövő és a Remény. Ezekben a lapokban arányaiban sokkal több eredeti szövege jelent meg, mint a többi budapesti hírlapban vagy folyóiratban, ami részben „emancipációs tanmeséinek” köszönhető, amelyeket célzottan ezen lapok számára írt. Az első világháborút és forradalmakat követő időszakban Cholnoky irodalompolitikai tevékenységet is kifejtett a lapok hasábjain. A korabeli prominensek emiatt filoszemitának könyvelték el a szerzőt (noha az irodalmi élet perifériájára csak 1925 után sodródott), megnehezítve publikációs tevékenységét és egzisztenciája szinten tartását. A tanulmány Cholnoky ezekben a lapokban kifejtett tevékenységét, valamint egy, az Egyenlőségben és a Múlt és a Jövőben publikált elbeszélés érdekes metamorfózisát mutatja be.

Los medios de pago en el largo plazo. El caso de Buenos Aires, del dinero virreinal al dinero bancario
Authors: Wasserman Martín
Published: July 2024

El propósito del artículo consiste en evidenciar que todo medio de pago admitido como dinero conlleva tanto la materialización de un compromiso asumido por su emisor como beneficios potenciales resultantes de la provisión de instrumentos transaccionales admisibles. Consecuentemente, los cambios materiales e institucionales experimentados en el largo plazo por los medios de pago han implicado modificaciones en los modos de formular aquellos compromisos y en la manera de negociar la distribución de los beneficios reportados. El caso del Río de la Plata, una economía carente de producción metalífera local, ofrece un observatorio para comprender el modo en que distintos gobiernos materializaron sus compromisos en medios de pago y distribuyeron los beneficios obtenidos de su provisión, lo que demuestra los cambios experimentados entre el periodo hispánico y el posrevolucionario a fin de focalizar, entonces, en el cambio que abrió la puerta a un periodo cuya matriz se sostiene desde entonces: la irrupción del sistema bancario y sus instrumentos de pago.

Bu çalışmada Human Immunodeficiency Virus (HIV) infeksiyonu nedeniyle polikliniğimizde takip edilen hastalarda hepatit prevalansını görmek amaçlandı. Ocak 2018-Aralık 2022 yılları arasında Dr. Lütfi Kırdar Kartal Şehir Hastanesi Enfeksiyon Hastalıkları ve Klinik Mikrobiyoloji polikliniği’nde takip edilen 530 HIV pozitif hasta hepatit serolojisi açısından retrospektif olarak incelendi. Hastalara ilk başvuru sırasında hepatit A virüs (HAV) immunglobulin (Ig) G, hepatit B yüzey antijeni (HBsAg), hepatit B kor antikoru (anti-HBc), hepatit B yüzey antijenine karşı antikor (anti-HBs) ve hepatit C virus antikoru (anti HCV) bakıldı. Hepatit A infeksiyonuna karşı 412 (%77.8) hastanın bağışıklığı mevcuttu. On sekiz (%3.4) hastada HBsAg pozitifliği, 73 (%13.8) hastada anti-HBc ve anti-HBs pozitif tespit edildi, 47 (% 8.9) hastada izole anti-HBc pozitifliği mevcuttu. Aşılama sonrası 180 (%34.0) hastada anti-HBs pozitifliği gelişmişti. Hepatit B ile hiç karşılaşmayan 212 (%40.0) hasta vardı. Dört (%0.7) hastada anti HCV pozitifliği vardı. HIV pozitifliği ile takip ve tedavisine başlanan her hastanın hepatit B virüsü (HBV) ve hepatit C virüsü (HCV) açısından taranması, HIV/HBV veya HIV/HCV ko-infeksiyonu tespit edilen hastalarda sirozu ve olası karaciğer kanseri riskini önlemek için uygun tedavilerin seçilmesi, HBV ‘ye karşı bağışıklığı olmayanların aşılanması, pediatrik yaş grubu dışında geçirildiğinde fulminan seyredebilen hepatit A’ya karşı bağışıklığın tespiti, gereğinde aşılanmalarının sağlanması önemlidir.
Oral Assessment Model: Assessing the Quality of Pronunciation in English Reading
Authors: Sun Xiaoming
Published: July 2024

When learning English, it is very important to correct the wrong pronunciation. This paper briefly introduces the speech recognition-based mispronunciation recognition algorithm and the mispronunciation recognition algorithm based on prior text. An accent recognition loss function is added to the algorithm based on prior text to improve its performance. After that, the performance of the algorithm is tested by using LibriSpeech and L2-Arctic datasets in the simulation experiment. When the number of hidden layers was 5 and the number of neurons in each hidden layer is 256, the proposed recognition algorithm performs the best. The algorithm converged faster during training, and the loss function is the smallest when it is stable. The proposed algorithm had the best recognition performance on both datasets, and the accent in L2-Arctic has little influence. The average recognition time of the proposed algorithm for the datasets is the least.

Published: July 2024

In the context of low-carbon and circular economy, this study aimed to develop a method for producing biofuels rich in hydrogen, using exclusively waste materials as energy sources or beneficial additives. Selected materials were forest and agricultural wastes as feedstocks, as well as demolition wastes from construction activities and red mud (RM) waste from the aluminum industry as a novel CO2 sorbent and catalyst, respectively. The experiments were carried out in a fixed-bed gasification system under a steam atmosphere and a thermogravimetric-mass spectrometric unit. The effects of temperature, sorbent/fuel ratio, and catalyst loading on final conversion, product gas composition and heating value, hydrogen yield, and energy recovery were examined, and optimum conditions were determined. At 750°C, Ca/C = 1, and RM loading 20–30% wt, the amount of CO2 captured by the building demolition waste sorbent was 76.5–81.2%, the molar fraction of hydrogen in the product gas 74.8–77.1% mol (raised up to 77% as compared to reaction without sorbent or catalyst), the hydrogen yield 1.31–2.08 m3/kg, the higher heating value (HHV) of gas 13.4–13.6 MJ/m3, and fuel conversion 71–100%. For the same proportions of sorbent and catalyst at 850°C, 64.3–77.8% of CO2 was captured, the hydrogen concentration in product gas was 76.6–79.8% mol, the yield was 1.5–2.35 m3/kg, the HHV of gas was 12.4–13.2 MJ/m3, and the conversion of organic matter was 88.1–100%.

Purpose: To explore how race and residential zip codes' socioeconomic index (SES) influenced COVID-19 testing rates in St. Louis during the early and peak phases of the pandemic.
Method: An ecological study was conducted using COVID-19 testing data from March to November 2020 in St. Louis City. The study included 16,915 individual tests from 30 residential zip codes.
Results: The overall testing rate in St. Louis was 303.97 per 10,000 population. Testing rates among Blacks, Whites, American Indian/Alaskan Natives, and Asians were 374.26, 247.77, 360.63, and 242.41 per 10,000, respectively. Higher testing rates were observed in low and middle SES zip codes compared to high SES zip codes. Adjusted for SES, testing rates were 1.68% higher among Blacks and 0.43% higher among American Indian/Alaskan Natives compared to Whites, and 0.033% lower among Asians. Geographical mapping showed higher testing rates in the inner core and lower rates in the periphery of St. Louis.
Conclusion: Race and SES influence testing rates. Areas with low testing rates should be targeted for intervention in St. Louis.
