Background: Significant data gaps exist for children and adolescents with drug-resistant (DR) TB, particularly from high TB incidence settings. This report provides a descriptive analysis of programmatic outcomes among children and adolescents treated for DR-TB in Pakistan. Methods: We extracted programmatic data from January 2014 to December 2019 from a tertiary care hospital with specialised child and adolescent DR-TB services. A physician assessed all children and adolescents (0–19 years) with presumptive DR-TB, including details of exposure to DR-TB, medical history, radiology, and laboratory results. All patients received treatment as per national DR-TB management guidelines based on WHO recommendations. Results: There were 262 treatment episodes for 247 patients enrolled during the study period. The median age of the cohort was 16 years (IQR: 13–18 years) with 16 (6.1%) children being under 5 years; 237 (90.5%) patients had pulmonary TB. The majority of the patients (194 or 74.1%) experienced a favourable treatment outcome and 26 (9.9%) died while on treatment. Female patients (78.5%) were more likely to experience favourable outcomes compared to males (64.7%; chi-sqr p-value = 0.02). Conclusions: We found high rates of favourable outcomes in children and adolescents treated for DR-TB. However, there were few young children in our cohort and there was a considerable gender gap that enhanced efforts to diagnose DR-TB in young children and to elucidate and mitigate the reasons for poor outcomes amongst males.

Background: Hesitancy remains one of the major hurdles to vaccination, regardless of the fact that vaccines are indisputable preventive measures against many infectious diseases. Nevertheless, vaccine hesitancy or refusal is a growing phenomenon in the general population as well as among healthcare workers (HCWs). Many different factors can contribute to hesitancy to COVID-19 vaccination in the HCWs population, including socio-demographic characteristics (female gender, low socio-economical status, lower age), individual beliefs regarding vaccine efficacy and safety, as well as other factors (occupation, knowledge about COVID-19, etc.). Understanding the determinants of accepting or refusing the COVID-19 vaccination is crucial to plan specific interventions in order to increase the rate of vaccine coverage among health care workers. Methods: We conducted a cross-sectional online survey on HCWs in seventeen Italian regions, between 30 June and 4 July 2021, in order to collect information about potential factors related to vaccine acceptance and hesitancy. Results: We found an overall vaccine uptake rate of 96.4% in our sample. Acceptance was significantly related to job task, with physicians showing the highest rate of uptake compared to other occupations. At univariate analysis, the HCWs population’s vaccine hesitancy was significantly positively associated with fear of vaccination side effects (p < 0.01), and negatively related to confidence in the safety and efficacy of the vaccine (p < 0.01). Through multivariate analysis, we found that only the fear of possible vaccination side effects (OR: 4.631, p < 0.01) and the confidence in vaccine safety and effectiveness (OR: 0.35 p < 0.05) remained significantly associated with hesitancy. Conclusion: Action to improve operator confidence in the efficacy and safety of the vaccine should improve the acceptance rate among operators.

Published: December 2022

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a pathogen with enteric tropism. We compared the clinical, biochemical and radiological features of children hospitalized for acute SARS-CoV-2 infection, classified in two groups based on the presence of diarrhea. Logistic regression analyses were used to investigate the variables associated with diarrhea. Overall, 407 children were included in the study (226 males, 55.5%, mean age 3.9 ± 5.0 years), of whom 77 (18.9%) presented with diarrhea, which was mild in most cases. Diarrhea prevalence was higher during the Alpha (23.6%) and Delta waves (21.9%), and in children aged 5–11 y (23.8%). Other gastrointestinal symptoms were most commonly reported in children with diarrhea (p < 0.05). Children with diarrhea showed an increased systemic inflammatory state (higher C-reactive protein, procalcitonin and ferritin levels, p < 0.005), higher local inflammation as judged by mesenteric fat hyperechogenicity (adjusted Odds Ratio 3.31, 95%CI 1.13–9.70) and a lower chance of previous immunosuppressive state (adjusted Odds Ratio 0.19, 95%CI 0.05–0.70). Diarrhea is a frequent feature of pediatric COVID-19 and is associated with increased systemic inflammation, which is related to the local mesenteric fat inflammatory response, confirming the implication of the gut not only in multisystem inflammatory syndrome but also in the acute phase of the infection.

Published: December 2022

The compatibility of sediments in terms of grain size, composition and colour among beaches and strategic sediment deposits (SSD) along Western Sardinia (Western Mediterranean Sea) were assessed to explore management strategy in the protection and adaptation to counteract the beach erosion and the effect of sea level rise along sandy shores. Twelve beaches, mainly conditioned by geological control, due to the presence of extensive rocky outcrops in the sea, enclosed in seven sedimentary cells (defined by the continuity of sediment transport pathways and by identification of boundaries where there are discontinuities), were characterised in terms of sediment composition and grain size. One hundred ninety-three beach sediments and one hundred sediments from SSDs were collected and analysed for sediment grain size, carbonate content and sediment colour. The beach sediments are composed by gravel to fine sands (D50: from 81 µm to 4986 µm) with siliciclastic and biogenic carbonate sediments mixed in different proportions (0–100% in CaCO3). The SSDs sediments are gravels to medium-fine sand (D50: from 96 µm to 1769 µm) composed by biogenic carbonate sands mixed with siliciclastic grains (0–100% in CaCO3). To be able to evaluate the compatibility between the beaches and SSDs, a multivariate statistical procedure was applied to grain size dataset. Our results show that 8 beaches have strategic deposits of compatible grain size and composition, whereas only 2 beaches have compatible strategic deposits of both grain size and colour. This may be related to the different sediment sources and depositional processes of sediment along the coastal cells and the continental shelf.
Bioponics as a Promising Approach to Sustainable Agriculture: A Review of the Main Methods for Producing Organic Nutrient Solution for Hydroponics
Authors: Szekely Iris , Jijakli M. Haïssam
Published: December 2022

Hydroponics is a soilless cultivation technique in which plants are grown in a nutrient solution typically made from mineral fertilizers. This alternative to soil farming can be advantageous in terms of nutrient and water use efficiency, plant pest management, and space use. However, developing methods to produce nutrient solutions based on local organic materials is crucial to include hydroponics within a perspective of sustainability. They would also allow hydroponics to be developed in any context, even in remote areas or regions that do not have access to commercial fertilizers. This emerging organic form of hydroponics, which can be qualified as “bioponics”, typically recycles organic waste into a nutrient-rich solution that can be used for plant growth. Many methods have been developed and tested in the past three decades, leading to greatly heterogenous results in terms of plant yield and quality. This review describes the main organic materials used to produce nutrient solutions and characterizes and categorizes the different types of methods. Four main categories emerged: a “tea”-type method, an aerobic microbial degradation method, an anaerobic digestion method, and a combined anaerobic-aerobic degradation method. The advantages and drawbacks of each technique are discussed, as well as potential lines of improvement. This aims at better understanding the links between agronomic results and the main biochemical processes involved during the production, as well as discussing the most suitable method for certain plants and/or contexts.

Published: December 2022

This study assessed the spatiotemporal variability and pollution grades of heavy metals in water and sediments of Bahr El-Baqar drain, Eastern Nile Delta, Egypt, by integration of geochemical analysis, metal pollution indices, correlation, and multivariate statistical analyses. Twenty samples of water and sediments were collected during 2018 and analyzed for heavy metal concentrations using ICP-OES. Heavy metal contents in the water samples followed the order: Fe > Zn > Al > Pb > Mn > Cu > Ni. The drain sediments were highly contaminated with heavy metals that followed the order: Fe > Al > Mn > V > Zn > Cu > Cr > Ba > Ni > Pb > As. Spatiotemporally, most metals in the drain sediments showed a decreasing trend from upstream (south) to downstream sites (north). Results of principal component analysis (PCA) supported those from the Pearson correlation between investigated heavy metals. In water, Mn, Ni, Pb, Zn, Cu, and Fe showed highly significant correlations. In sediments, Ba, Ni, Zn, Fe, Al, Mn, and V showed strong positive correlations indicating that these metals were derived from similar anthropogenic sources. The calculated metal pollution indices: enrichment factor (EF), contamination factor (CF), pollution load index (PLI), degree of contamination (DC), and index of geo-accumulation (Igeo) indicated high loadings of heavy metals in the drain sediments. EFs revealed low, moderate to significant enrichment, whereas CFs showed low, moderate, and considerable contamination. PLI indicated low, baseline, and progressive contamination, while DC indicated low, moderate, and considerable degree of contamination. Igeo of all investigated metals (except for As; class 1) indicated extremely contaminated sediments (class 7).
Analytical Method for Groundwater Seepage through and Beneath a Fully Penetrating Cut-off Wall Considering Effects of Wall Permeability and Thickness
Authors: Mei Jinling , Cao Hong , Luo Guanyong , Pan Hong
Published: December 2022

A fully penetrating cut-off wall is a vertical seepage barrier that fully penetrates an aquifer and is embedded in an underlying aquitard to a certain depth. Groundwater seepage with this type of wall occurs through three paths: leakage through the body of the wall in the aquifer, leakage through the body of the wall embedded in the aquitard, and seepage under the wall. Seepage through the first path can be simply treated as one-dimensional flow. However, due to the mutual influence of seepage through the latter two paths, the seepage problem is complicated and still needs to be studied. An analytical method is proposed to solve this problem in this study. Mathematic expressions for flow rate and head value are obtained by superposition of drawdowns of two exact models, namely, the model with only leakage through the wall body and the model with only seepage under the wall, respectively. Exact solutions are quoted or derived for the exact models, but they involve Legendre’s elliptic integrals of the first and third kinds. To facilitate an engineering application, approximate models of the exact models are introduced and their solutions are applied to the analytical formulas. The accuracy and applicability of the proposed method are verified compared with the numerical method. The proposed method provides a simple but effective method for quickly estimating the quantity of seepage in the aquitard (including leakage through the wall body and seepage under the wall) when simultaneously considering the effects of wall permeability and thickness.
Flood Damage on Dairy Farms: A What-If Analysis to Assess Economic Losses
Authors: Gaviglio Anna , Marescotti Maria Elena , Demartini Eugenio , Corradini Annafrancesca
Published: December 2022

Although the impact of floods on the agricultural sector is relevant, with potential consequences on food security, in the new EU Common Agricultural Policy (CAP) proposal, agricultural risk management tools have been reinforced and extended. As far as we know, guidelines for the estimation of insurance indemnities related to flooding damage in the European livestock sector have not been proposed yet, unlike what has occurred in extra-European contexts. The present research proposes a model to identify the components of flood damage on dairy farms aimed at categorizing the cost typologies related to flood events by implementing a what-if approach. Our results highlight that collecting data about the vulnerability of a farm is an essential condition to assess the severity of damage from an economic perspective. In fact, even if some of the variables considered cause large economic losses per se, others are mainly related to poor management of issues related to the health of the herd (i.e., mastitis, lameness, other diseases). Such issues can be exacerbated by floods. Herd management, which includes comprehensive data collection, is essential for the calculation of economic losses in a single farm case and is also indispensable for the calculation of indemnity for the recovery of farming activities.

Removal of Environmentally Harmful and Hardly Degradable Pharmaceuticals Sulfamethoxazole, Diclofenac, and Cetirizine by Adsorption on Activated Charcoal
Authors: Pavúková Daniela , Fašková Lucia , Melníková Eva , Mališová Emília , Híveš Ján , Štibrányi Ladislav , Hudec Pavol , Naumowicz Monika , Gál Miroslav
Published: December 2022

The removal of three environmentally harmful and hardly degradable pharmaceuticals, namely sulfamethoxazole, diclofenac, and cetirizine, from aqueous solution by the adsorption onto two types of activated charcoals (WSCl2 and HWOH) was investigated. The volume of micropores and mesopores in two charcoals was the main property affecting removal efficiencies. Using microporous WSCl2 as an adsorbent, higher removal efficiencies were achieved for all chosen pharmaceuticals. The highest removal efficiency was recorded in the case of sulfamethoxazole (79%). A direct correlation between log Kow and removal efficiencies and between the solubility of pharmaceuticals and removal efficiencies was not found. The adsorption behavior of individual pharmaceutical solutions can be described by the pseudo-second order kinetic model. The parameters obtained from the kinetic model show that the adsorption rate on HWOH was higher than on WSCl2. However, the amounts of adsorbed pharmaceuticals were lower on HWOH than on WSCl2, which can be linked to the textural difference between the charcoals. In the mixture consisting of all three compounds, overall removal efficiencies were lower than in the case when individual pharmaceuticals were present in the solution. Results also indicate that a certain fraction of the micropores can only be occupied by the smallest compound in the mixture (sulfamethoxazole).

Published: December 2022

The operation process of a virtual power plant is affected by many uncertainties, and how to ensure its comprehensive operation quality is a pressing challenge. For the virtual power plant incorporating electric vehicles, the interval number is used to describe the stochastic fluctuation of system uncertainties, and the optimization objectives are to (1) improve the operating economy, environmental protection, and grid load smoothing, (2) build a multi-objective interval optimal dispatching model considering the constraints of power balance and equipment operating characteristics, (3) solve the Pareto solution set by adopting the improved NSGA-II algorithm incorporating extreme scenario analysis, and (4) determine the optimal dispatching solution by the hierarchical analysis method. The median values of the determined optimal target intervals are 6456.11 yuan, 9860.01 kg, and 2402.56 kW. The algorithm shows that the proposed optimal dispatching strategy can effectively improve the economy of the virtual power plant and ensure that environmental protection and grid load smoothing requirements are met.
Electric Vehicle Charging Data Analytics of Corporate Fleets
Authors: Gonçalves Frederico , de Abreu Borges Liselene , Batista Rodrigo
Published: December 2022

The advances in electric mobility, motivated by current sustainability issues, have led public and private organizations to invest in the electrification of their corporate fleets. To succeed in this transition, companies must mitigate the impacts of electrification on their fleet operation, in particular the ones on vehicle recharging. The increase in energy demand caused by electrification may require changes in the company electrical infrastructure, the installation of charging stations, and the proper planning of the recharging schedule, considering the particularities of each fleet and operation. In this context, data analytics is seen as an important tool to help companies to understand their charging fleet profile, supporting decision makers in making data-driven decisions regarding their charging infrastructure. This paper shows how data analytics could be applied to analyze the charging data of corporate electric fleets, adopting a business-oriented analysis method based on the Cross Industry Standard Process for Data Mining (CRISP-DM) methodology. The analyses were performed on data collected from three different companies, with each one of them operating fleets of vehicles of different categories, i.e., ultra-light, light, and heavy vehicles. The results illustrate how data analytics, based on interactive reports and dashboards, can shed light on business questions related to the operation of electric vehicle corporate fleets.
A Descriptive Systematic Review of Food Insecurity and Intimate Partner Violence in Southern Africa
Authors: Macassa Gloria , Francisco Jose da Cruz , Militao Elias , Soares Joaquim
Published: December 2022

Food insecurity and intimate partner violence are important determinants of health and wellbeing in southern Africa. However, very little research has attempted to investigate the association between them even though food insecurity is anticipated to increase in the region, mostly owing to climate change. The objective of this paper was to descriptively review peer reviewed studies that investigated the relationship between food insecurity and intimate partner violence in southern Africa. Literature searches were carried out in Scopus, Web of Science and PubMed databases without any time restriction. A total of five studies that investigated the association between food insecurity and intimate partner violence were identified in South Africa and Swaziland. Of these four studies used a cross-sectional design, and one employed a longitudinal design. Samples varied from 406 to 2479 individuals. No empirical studies were found for the remaining southern African countries of Angola, Botswana, Malawi, Namibia, Zambia, Zimbabwe, Lesotho, and Mozambique. Moreover, the reported findings indicated that there was an association between food insecurity and interpersonal violence (i.e., physical, psychological, and emotional) in the sub-region regardless the fact that the five studies used diverse measurements of both food insecurity and intimate partner violence.
Dostoevsky's polyphony versus postmodern nomadism
Authors:   Сulture studies department, GITR Film and Television School, Stroeva O.V.
Published: December 2022

The paper is devoted to the variability of interpretations of F. Dostoevsky in the existential-postmodernist key due to the polyphonic mechanism inherent in the works of the great writer. The question of F. Dostoevsky's influence on F. Nietzsche and other non-classical philosophers has been considered by Western thinkers since the 19th century which led to the understanding of the writer's work in the West as an example of existentialist drama, the aesthetics of tragic absurdity and complex psychology. Existentialist quests and ideas of non-classical philosophy were reflected further in the postmodern aesthetics, where the concept of so-called nomadic subjectivity has been formed — the one that is in the process of permanent formation deprived of selfintegrity. The principal concern of this study is to correlate the model of postmodern “flickering differance” described by the philosophers with the provisionary model of the polyphony of the great Russian writer. The specific model of postmodern subjectivity finds its embodiment not only in the experiments of modern auteur cinematography but also in the trends of mass film industry. Thus, the undertaken analysis is focused not only on direct adaptations of the writer's works but also the most popular screen works of recent years, including series, both foreign and domestic. Opposed to the pessimism and hopelessness of postmodernism F.M. Dostoevsky shows in his works the way out of the existential crisis, proposing a coordinate system for assembling. F.M. Dostoevsky’sworks are highly relevant today as never before, as they teach a mature approach to rendering an accountof the formation of subjectivity.
ROLE OF MEDIATION IN A CONFLICT RESOLUTION
Authors: Kuziv M.
Published: December 2022

The article considers the role of mediation to conflict resolution. The problem of mediation is disclosed as an alternative way of resolving disputes. It has been revealed that in all the concepts of mediation the participation of a third party is emphasized that of the mediator who provides some assistance in establishing an understanding and whose interests are not directly related to the misunderstanding issues. An active third party controls the process, facilitates a realistic assessment of the situation by the   parties, adopts an adequate solution, reduces emotional stress, etc. The expediency and possibilities of using mediation in Ukraine are analysed. It has been investigated that presently Ukrainian legislation has not yet defined the legal status of a mediator as well as that of professional mediator organizations and the procedure for certification of mediators, additional requirements for professional mediation skills and the quality of services provided and similar requirements. In the current legislation of Ukraine there is no regulation of the relations between the mediation participants.The types of mediation and its techniques have been considered. Such kinds of mediation as preventive mediation and mediation of conflict that has already arisen, survey mediation, mediation of containment (escalation) of the conflict, conflict settlement mediation, of voluntary and obligatory types, mediation focused on problem solving, transformation, rehabilitation, assessment mediation and mediation, based on mutual understanding, as well as reflexive, contextual and independent intervention techniques have been dealt with. These should be used for the success and effectiveness of the mediation process.It has been found that the use of mediation has proven its appropriateness for solving a variety of conflicts, but the real effectiveness of mediation also depends on the mediator's professionalism, the type of conflict and the personal characteristics of the conflicting parties.

ECONOMIC ASPECTS OF CRYPTOCURRENCY MINING
Authors: GONAK Igor
Published: December 2022

Introduction. Economic development of Ukraine in the third decade of the 21st century largely depends on the development of digital technologies, on which the cryptocurrency busi­ness directly depends. According to the Index proposed by chainalysis.com, Ukraine is one of the leaders in the world and the undisputed leader in Europe in the adoption of cryptocurrencies. This became possible thanks to the active development of financial and information technol­ogies in Ukraine, and the financial, economic and military-political crises only give additional impetus to the development of the cryptocurrency business due to its global nature and full or indirect independence from attempts at state regulation. One of the areas of cryptocurrency business development is cryptocurrency mining.

The purpose of the article is to reveal the algorithm of conducting business in the field of cryptocurrency mining and the economic efficiency of mining in Ukraine and the possibility of its impact on economic growth in the country.

Results. Cryptocurrency mining is the process of creating cryptocurrency coins. It has been investigated that the cryptocurrency mining process is not a financial pyramid or some kind of virtual game, but is one of the newest types of business activity, which requires significant the­oretical and practical economic and technical knowledge, is economically expedient both in the short and long term.

When mining, you can use a variety of computer equipment, depending on the miner’s economic tasks and desired results. ASIC equipment has been developed for mining on an industrial scale. Cloud mining is used for investing. If there is no knowledge about mining and limited financial resources, you should use browser mining or mine on your own PC, laptop or smartphone. However, the most efficient and widespread mining takes place on video cards. It was found to be a by-product of mining. It is estimated that there is a slight correlation between the earnings of miners on the Ethermine mining pool and the daily mining profit.

Conclusions. Although the history of cryptocurrency business is only one and a half decades, mining, as an object of business activity in Ukraine, is a significant economically effective type of business activity, which is noted in the world rating of the perception of cryptocurrencies, according to which Ukraine is one of the world leaders. Attempts to implement legal regulation of cryptocurren­cy mining both in Ukraine and in other countries, and its gradual implementation do not significantly harm the creation, distribution and use of cryptocurrency coins, however, will create transformed conditions for the economic attractiveness of cryptocurrency mining as business objects.

Published: December 2022

Squamous cell carcinoma of the penis is rare in daily practice. Epidermal growth factor receptor is widely overexpressed in this type of cancer. In a metastatic situation, chemotherapy has modest efficacy. Agents targeting this receptor, including Cetuximab, are effective as monotherapy or in combination with chemotherapy. The finding was fortuitous in the anatomopathological analysis of a resection specimen for phimosis. It progressed first to the inguinal lymph nodes 3 months after surgery and then rapidly to the lungs and liver after the first line of chemotherapy. Cetuximab monotherapy in the second line of therapy was well tolerated and showed a complete response after 6 months of treatment. This response has been maintained for 5 years of treatment. The efficacy of agents targeting the Epidermal Growth Factor Receptor in squamous cell carcinoma of the penis opens the way to therapeutic optimization.

A quantitative assessment of the influence of the uncertainty in meteorological elements during the period of the lead time of long-term river runoff forecasts on their error is proposed. Examples of such assessment are given for long-term forecasts of various characteristics of the water inflow into the Cheboksary Reservoir and the runoff of rivers in the Oka, Kama, Tobol and Don basins, which were obtained using the ECOMAG, DWAT, HBV river runoff formation models and the ensemble approach. It is shown that the influence of the uncertainty in the course of meteorological characteristics depends not only on climatic conditions of the formation of river runoff, but also on the accuracy of its modeling. As increasingly advanced river runoff formation models are introduced, this uncertainty will become the main factor determining the quality of its forecasting. Keywords: river runoff, forecast, lead time, error, meteorological elements, uncertainty, assessment

Innovative methodologies between supply and demand
Authors: Luna Diego , Pineda-Alfonso José Antonio
Published: December 2022

At present, educational discourses on innovative methodologies make up an enthusiastic panorama that is not exempt from criticism. The aim of this paper is to understand the real possibilities of success for new methodological proposals in a case study focused on the Geography and History classes of a teacher–researcher. The results obtained allow us to identify a central category of analysis, “methodological ineffectiveness”, and two subcategories, “methodological supply” and “methodological demand”. This confirms the importance of exploring the impact of new methodologies based on the factors and voices specific to each educational context.

Investigation on the Interrelationship between the Chemical Composition, Heat Treatment Parameters and the Phase Transformation Process, Microstructure Evolution and the Mechanical Properties of Austempered Steel
Authors: Okwonna O. C , Chima O.M.
Published: December 2022

The interrelationship between chemical composition, heat treatment parameters, and phase transformation, microstructural evolution and the mechanical properties of austempered steel was studied. Two samples of steel with different percentage composition of carbon of 0.56 and 0.76 were used for the study. They were austentized at the respective temperatures of 8000C, 8400C, 9000C and 9600C for 30 minutes. They were thereafter quenched using bitumen-palm kernel oil, and subjected to austempering isothermal heat treatment at 4200Cfor different time durations of 5, 15, 30, 45 and 60 minutes. The samples were tested for tensile strength, elongation, hardness and impact strength. They were also subjected to microstructural characterization to determine the phases in the microstructures and their effects on the properties of the developed materials. Results obtained revealed that the dominant phases in the microstructure were bainite, matensite and traces of retained austenite. It was found that decreasing austenitizing temperature yields finer grain structures with increase in tensile strength and elongation with decrease in hardness and relatively little effect on the impact strength. At any given austenitizing temperature, shorter austempering holding time yielded optimum properties in tensile strength and elongation while higher hardness values were associated with shorter holding time. These results proved that the process conditions have strong correlation with both the microstructures and the mechanical properties. It was concluded that the most promising microstructures with respect to excellent strength-ductility property are those obtained at the ausenitizing temperature range of 800 -8400C for the austempering time range of 5 – 30 minutes. These materials have potential for load bearing application while those austenitized within the range of 900 - 9600C using austempering time range of 5 – 15 minutes are candidate material for wear resistant application.

A STUDY ON DYNAMIC RELATIONSHIP BETWEEN GOLD PRICE AND STOCK MARKET PRICE IN INDIA
Authors: Panchal Nilam
Published: December 2022

Gold has always been contemplate an attractive investment in India and its excellent performance in recent years has substantially confirmed the wisdom of that tradition. When markets are volatile the investors are into panic and so they tend to move out the risky assets they have invested such as stock and invest into assets such as gold. The main objective of the paper is to analyse the effect of Gold prices on Indian stock market represented by Nifty-50. This study is based on the secondary data collected which investigates the homogeneity between Gold price and Stock market price (Nifty) by using daily time series data from January 2018 to May 2021.
Ultra-diffuse Galaxies as Extreme Star-forming Environments. I. Mapping Star Formation in H i-rich UDGs
Authors: Kado-Fong Erin , Greene Jenny E. , Huang Song , Goulding Andy
Published: December 2022

Ultra-diffuse galaxies (UDGs) are both extreme products of galaxy evolution and extreme environments in which to test our understanding of star formation. In this work, we contrast the spatially resolved star formation activity of a sample of 22 H i-selected UDGs and 35 low-mass galaxies from the NASA Sloan Atlas (NSA) catalog within 120 Mpc. We employ a new joint spectral energy distribution fitting method to compute star formation rate and stellar mass surface density maps that leverage the high spatial resolution optical imaging data of the Hyper Suprime-Cam Subaru Strategic Program and the UV coverage of the Galaxy Evolution Explorer, along with H i radial profiles estimated from a subset of galaxies that have spatially resolved H i maps. We find that UDGs have low star formation efficiencies as a function of their atomic gas down to scales of 500 pc. We additionally find that the stellar mass-weighted sizes of our UDG sample are unremarkable when considered as a function of their H i mass—their stellar sizes are comparable to NSA dwarfs at fixed H i mass. This is a natural result in the picture where UDGs are forming stars normally, but at low efficiencies. We compare our results to predictions from contemporary models of galaxy formation, and find in particular that our observations are difficult to reproduce in models where UDGs undergo stellar expansion due to vigorous star formation feedback should bursty star formation be required down to z = 0.
