Emissions of reactive nitrogen compounds (RNCs) from two vehicles with turbo-charged spark ignition engines over cold start driving cycles
Authors: Woodburn Joseph
Published: April 2021

This paper reviews the emissions of reactive nitrogen compounds (RNCs) from modern vehicles fitted with spark ignition en-gines and three-way catalysts. Specific aspects of the pollutants involved – and their formation – are discussed. Cold start driving cycles are scenarios under which emissions of all four RNCs can be significant; the mechanisms behind emissions trends are ex-plored. Experimental data obtained from two vehicles tested over two different cold start driving cycles are presented and analysed. The use of gravimetric and molar metrics are explored. Ammonia, a species which is currently not regulated for passenger cars in any automotive market, is identified as forming the majority of the RNC emissions over the entire driving cycle. While ammonia emissions are strongly linked to aftertreatment system warmup and periods of high load, significant ammonia emissions were also measured under certain hot-running, low load conditions, and even at idle. For the majority of the duration of the test procedures employed, the RNC profile was dominated by ammonia, which accounted for between 69% and 86% of measured RNCs in the ex-haust gas. Emissions are compared to the available legislative precedents (i.e. emissions limits currently in force in various jurisdic-tions). Finally, possibilities for control of exhaust emissions of currently unregulated RNCs are briefly discussed.

Sardinia is the second largest islandin the Mediterranean region, receiving significant attention due to its interesting fauna and flora. The last checklist of Sardinian ants was published more than a decade ago, and,since then,it got outdated by numerous taxonomic and faunistic novelties. As a result of recentcollecting efforts across theisland,we presentthe first Sardinian records of Messor ibericus Santschi, 1931, Solenopsis lusitanica Emery, 1915(new to Italy), Temnothorax aveli Bondroit, 1918 and Tetramorium atratulum (Schenck, 1852), while proposing to consider Solenopsis fugax (Latreille, 1798)and Temnothorax affinis (Mayr, 1855) as absent. We report for the first time a parasite-host association between Tetramorium atratulum and Tetramoriumsemilaeve André, 1883, and the conspicuous presence of ergatogynes within a Solenopsiscolony (S. lusitanica).Morphological insights on the little-known S. lusitanica and S. orbula Emery, 1875 are also discussed.We combined the new findings and previous literature data intoan updatedchecklist of 77 taxaand discuss afirst biogeographic analysis of the Sardinian antsaided bychorotypes.Eurasian, European, Euro-Mediterraneanand West-Mediterranean taxa are the numerically prevalent groups, while the overall number of speciesis significantly lower than in the other large Mediterranean islands.

Liparthrum colchicumSemenov (Coleoptera Curculionidae Scolytinae) is a relatively unknown monophagous insect species primarily associated with thin dried twigs (about 0.5-1cm in diameter) of Laurel (Laurus nobilis). After being caught in traps located at Italian ports, it was initially considered an intercepted species alien to the country. However, recent findings, suggest that this beetle may have a different origin. Several records from different sites of Tuscany and Latium showed that it could be relatively widespread in Italy. These observations strengthened the hypothesis that this scolytid, harmless to L. nobilis, might be already established or even native to the country. Therefore, we argue that it could have been easily overlooked thus far, as it thrives only in twigs already wilted due to different environmental factors. Moreover, field observations, carried out in the two Italian Regions, evidenced high frequencies of its infestations in Laurel twigs previously colonized by Xylosandrus compactus. Notes on the taxonomy and biology of this species are also reported in the present wo
Butterflies and moths (Insecta: Lepidoptera) of the Lokrum island, southern Dalmatia
Authors:   Association Hyla, Lipovac I 7, HR-10000 Zagreb, Croatia, Koren Toni
Published: April 2021

In 2016 and 2017 a survey of the butterflies and moth fauna of the island of Lokrum, Dubrovnik was carried out. A total of 208 species were recorded, which, together with 15 species from the literature, raised the total number of known species to 223. The results of our survey can be used as a baseline for the study of future changes in the Lepidoptera composition on the island. In comparison with the literature records, eight butterfly species can be regarded as extinct from the island. The most probable reason for extinction is the degradation of the grassland habitats due to the natural succession as well as the introduction of the European Rabbit and Indian Peafowl. Their presence has probably had a tremendously detrimental effect on the native flora and fauna of the island. To conserve the Lepidoptera fauna of the island, and the still remaining biodiversity, immediate eradication of these introduced species is needed.

Este trabalho tem por objetivo mostrar metodologias, vivências e práticas usadas com crianças no meio religioso, chegando à observação da evangelização infantil na igreja Adventista. Detalho assim na primeira pessoa: a metodologia usada e o papel do pesquisador para a Sociologia, informando pontos positivos e negativos, e mostrando breves notas de campo. Trago observações, descrição, análise e interpretação do campo estudado, na Escola Sabatina, no grupo dos Primários da igreja Adventista, onde consegui observar e ver as contribuições da evangelização infantil para a socialização, através das aulas que assisti na igreja, dos desenhos que tive com as crianças, e das conversas com elas, e com os professores. Prossigo observando atividades e dados do grupo estudado, com desenhos. Por isso, sigo as metodologias já estudadas e pesquisadas por Pires (2011), Lewis (2006), Cohn (2005), Nunes (2007), Campos (2009), Santos (2011), Silva (2013), Falcão (2010). Com esses diálogos construí uma base metodológica, para seguir os percursos do meu campo de pesquisa. Portanto, esse material estudado rico no conceito de agência infantil me fez enveredar por uma área da Sociologia e Antropologia que começa a ter espaço.
A economia feminista e a crítica ao paradigma econômico predominante
Authors: Teixeira Marilane Oliveira
Published: April 2021

Este artigo trata do surgimento e do desenvolvimento da economia feminista como uma abordagem que se contrapõe à economia predominante, identificando as limitações teóricas e epistemológicas desta corrente para responder aos principais desafios da sociedade. Ao contestar os modelos preconizados pelos neoclássicos, estas economistas se propõem a um novo enfoque que integre a dinâmica da economia e o trabalho de reprodução como partes de um único sistema. Destaca-se, nessa abordagem, aquela que coloca no centro a sustentabilidade da vida humana. Fundamentado em bibliografia especializada o artigo percorre uma vasta literatura produzida nos últimos anos no campo da economia feminista. Essa abordagem ganhou relevância no Brasil somente nas duas últimas décadas e por iniciativa do movimento feminista organizado que, ao elaborar uma crítica às teses neoliberais e apontar as insuficiências da economia tradicional para indicar soluções aos dilemas de uma sociedade cindida por desigualdades seculares, buscou nessa literatura novos aportes teóricos e metodológicos para repensar uma nova economia. Nesse sentido, a economia feminista, com foco na sustentabilidade da vida humana, se constitui em um instrumento valioso de análise que permite uma crítica global ao sistema capitalista e à economia de mercado e, por isso, foi mais rapidamente incorporada pelos movimentos feministas que questionam o liberalismo econômico e a globalização.
Divisão sexual do trabalho sob a ordem neoliberal
Authors: Lapa Thaís de Souza
Published: April 2021

Este artigo procura trazer contribuições ao debate sobre a relação entre a divisão sexual e internacional do trabalho, procurando caracterizar não somente impactos do neoliberalismo sobre a divisão sexual do trabalho, mas mostrar, como vêm apontando sobretudo pesquisadoras feministas, que o gênero é um organizador chave da globalização neoliberal. Focalizo nessa discussão as dinâmicas da divisão sexual no trabalho assalariado e o uso estratégico da força de trabalho feminina em manufaturas que integram as cadeias globais de valor (com o exemplo emblemático da indústria eletroeletrônica), sem desconsiderar, porém, a indissociabilidade entre trabalho assalariado e reprodutivo.

Published: April 2021

Background: Male androgenetic alopecia (MAGA), also known as androgenetic alopecia, is the most common hair loss in males who have a genetic predisposition. The pattern of baldness in MAGA starts from the frontal area in a triangular pattern, followed by progressive thinning of the vertex until baldness occurs. Generally, the diagnosis of MAGA is established by clinical examination. FDA has approved a combination of topical minoxidil and oral finasteride for MAGA treatment. Currently, there is another treatment option like dutasteride, a prostaglandin analog, ketoconazole, and co-adjuvant therapy like laser therapy, hair transplantation, and so on. Purpose: To provide an updated treatment for MAGA. Review: Etiopathogenesis of MAGA is influenced by genetic susceptibility and hormonal factors. The European Consensus Group set the evaluation diagnosis of MAGA to include a historyof hair fall, physical examination, hair examination, supporting examination, and clinical documentation. There are therapeutic options for MAGA, including antiandrogen therapies, androgen-independent therapies, and co-adjuvant therapies. The FDA has approved a combination of topical minoxidil and oral finasteride for MAGA treatment. MAGA may affect patients’ quality of life and self-esteem. In general, patients expect higher. Conclusion: MAGA is the most common progressive hair loss in males. The MAGA therapy is expected to achieve cosmetically significant regrowth and to slow additional hair loss.

Published: April 2021

Purpose – of the study is to indicate the path of much needed segmentation in the Croatian tourist supply. Therefore, it aims to identify the destination-specific elements of bicycle destinations in Europe, within the context of cycle tourism demand. Design – While the quality of the tourist product is proportional to the level of logistics implementation and the rivalry on the tourist market is supply chain-based, the focus is on a crucial element of tourist supply chain management—information. Methodology – The study recognizes both counterparts on the market, although highlighting the tourist supply. The data on supply was collected by researching the internet information sources available to cycle tourists while making travel decisions. Findings on the destinations’ logistic product variables are compared to criteria set by the researched cycle tourism demand. Approach – This small-scale research of bicycle tourism supply aims at testing the selected criteria for the purpose of a sequential wider research oriented towards providing a list of possible upgrades for Croatian destinations. Findings – Among all features attributable to a destination, research demonstrated that the cycle tourists’ primary focus is on information accessibility. The cycling-specific supply recognizes this information dependency and targets the market by a variety of needed information, while general tourist sites often lack complete information. Value – Similar research of bicycle tourism does not exist. The field is mainly contributed to trough conceptual discussions and studies of existing practice. This research establishes to what extent the demand and supply side match by identifying the common attributes of cycle tourism destinations.

Published: April 2021

The history of public recognition of pesantren is closely related to the existence of figures in a pesantren. However, in today's development, various needs and challenges require pesantren to adapt in order to maintain their existence. The increasing number of students followed by various developments in needs and efforts to increase protection are the reason why a number of traditional pesantren transforming their spatial concept. This design transformation was carried out from open (inclusive) to closed (exclusive). On the other hand, this condition has implications for the role of pesantren in community empowerment. This is what happened at the Al-Hikmah 2 Benda Islamic Boarding School, one of the Islamic boarding school that has transformed its space from open to closed. From the existing background, the reasons and objectives of the researcher are to 1). Trace the inclusive and exclusive concepts that have been used by the AlHikmah 2 Benda Islamic Boarding School. 2). Analyze the impact of the application of concepts that have been used on pesantren and society. The research method used is naturalistic, with a key instrument is the researcher. The research results showed that the inclusive and exclusive concepts that have been used by the Al-Hikmah 2 Benda Islamic Boarding School were obtained, as well as the implications of the advantages and disadvantages of applying each of these concepts. Inclusive Islamic boarding schools have advantages in socio-economic interactions and the role of community empowerment but are constrained in efforts to protect students and community recognition, while the concept of exclusive pesantren has advantages in anticipating the protection of students but the role of pesantren in community empowerment is limited. However, there are inclusive spaces found in the exclusive layout of the AL-Hikmah 2 Benda Islamic Boarding School. These spatial concepts and models can be used and developed to deal with problems that arise from the application of each existing concept.

We investigate new graph characteristics namely total (vertex, edge) face irregularity strength of gen- eralized plane grid graphs Gmn under k-labeling Phi of type (Alpha, Beta, Gamma). The minimum integer k for which a vertex-edge labelled graph has distinct face weights is called the total face irregularity strength of the graph and is denoted by tfs(Gmn). In this article, the graphs G = (V;E; F) under consideration are simple, finite, undirected and planar. We will estimate the exact tight lower bounds for the total face irregularity strength of some families of generalized plane grid graphs.

Nutrition is one of the main environmental factors affecting the reproductive system. The modern diet is characterized by higher consumption of high-calorie foods, saturated fats, trans fats, refined grains and added sugar. Despite the heterogeneity of the populations studied, in general, the data confirm a steady downward trend in male sperm quality in most Western countries, including an increase in the prevalence of conditions such as complete asthenozoospermia (lack of motility) and isolated asthenozoospermia (low sperm motility due to varicocele, infections or genetic factors). Clear patterns between nutrition and fertility have been identified. Studies have shown a significant positive effect of additional exogenous micronutrient intake on total sperm count (ω-3 and CoQ10); sperm concentration (selenium, zinc, ω-3 and CoQ10); sperm motility (selenium, zinc, ω-3, CoQ10 and carnitine); morphology (selenium, ω-3, CoQ10 and carnitine). Additional exogenous intake of micronutrients that affect sperm can be used as an effective and safe factor in modulating male fertility.

Reproducing of the humidity curve of power transformers oil using adaptive neuro-fuzzy systems
Authors: Vasilevskij V.V. , Poliakov M.O.
Published: April 2021

Introduction. One of the parameters that determine the state of the insulation of power transformers is the degree of moisture content of cellulose insulation and transformer oil. Modern systems of continuous monitoring of transformer equipment have the ability to accumulate data that can be used to reproduce the dynamics of moisture content in insulation. The purpose of the work is to reproduce the curve of the of humidity of transformer oil based on the results of measuring the temperature of the upper and lower layers of oil without the need for direct measurement of moisture content by special devices. Methodology. The construction of a fuzzy neural network is carried out using networks based on adaptive neuro-fuzzy system ANFIS. The network generated using the Grid Partition algorithm without clustering and Subtractive Clustering. Results. The paper presents a comparative analysis of fuzzy neural networks of various architectures in terms of increasing the accuracy of reproducing the moisture content of transformer oil. For training and testing fuzzy neural networks, the results of continuous monitoring of the temperature of the upper and lower layers of transformer oil during two months of operation used. Considered twenty four variants of the architecture of ANFIS models, which differ in the membership functions, the number of terms of each input quantity, and the number of training cycles. The results of using the constructed fuzzy neural networks for reproducing the dynamics of moisture content of transformer oil during a month of operation of the transformer are presented. The reproducing accuracy was assessed using the root mean square error and the coefficient of determination. The test results indicate the sufficient adequacy of the proposed models. Consequently, the RMSE value for the network constructed using Grid Partition method was 0.49, and for the network built using the Subtractive Clustering method – 0.40509.
Optimization and reliability of the power supply systems of a compressor station
Authors: Benchouia N. , Saaidia M.
Published: April 2021

As gas pipeline systems become larger and more complex, the importance of optimally operating and planning these facilities has increased. The capital costs and operating expenses of pipeline systems are so large that even small improvements in the use of the system can involve large sums of money. Purpose. This article proposes a method to improve the reliability and optimization of power supply systems for compressor stations. The novelty of the proposed work is the development of a new mathematical model that allows the choice of the most appropriate maintenance policies in the best way to significantly reduce costs as well as to optimize useful key performance indicators – failure rate, average time between breakdowns, the average repair time for equipment in compressor station electrical supply systems. Applying graph theory to represent this mathematical model from the schematic diagram of the different energy sources with respect to the five compressor stations is adequate. Methods. The problem that arises for the future operator or operator is, among others, how to balance two main aspects: a technical aspect and an economic aspect. The proposed methodology introduces a research algorithm to calculate the optimal values of the operating parameters of the power supply systems of compressor stations by combining technical and economic aspects in order to reduce costs and increase performance indicators. The proposed algorithm can be implemented in FORTRAN code. Results. The algorithm developed is an efficient tool for calculating maintenance costs and allows by means of programming to define the most appropriate maintenance policy. On the other hand, this technique could be used as an essential economic evaluation indicator for other equipment in order to choose among all the technically possible solutions the one which allow obtaining the best economic result. Practical value. The proposed algorithm has been examined in this third variant of the supply system with two turbogenerators. The result of the optimization shows a clear preference for selecting station C for the pipeline as this presents the minimum cost which is the definition of the algorithm optimizer. Then, it is important to adopt the most recommended maintenance policies and practices in order to ensure the availability of the power supply systems and to avoid unplanned outages with the resulting loss of production.
Enhancing graduate employability through targeting ePortfolios to employer expectations: A systematic scoping review
Authors: Mitchell Lana , Campbell Chris , Somerville Mari , Cardell Elizabeth , Williams Lauren
Published: April 2021

Electronic portfolios (ePortfolios) are increasingly being used in university degrees to showcase graduate employability. However, evidence on employers’ views and use of ePortfolios has not been synthesised. This study aimed to systematically review the evidence on employer, industry representative and university educator views on the use of ePortfolios in recruiting graduates, including recommended ePortfolio content. Six databases were searched to identify original research on views and utilisation of ePortfolios published since 2000. Studies were screened in duplicate, and the full texts of 163 articles reviewed. Included studies were synthesised to reveal common themes. The 17 included studies represented a range of industries and most were conducted in the USA (n=10). Awareness of ePortfolios was low, as was use within recruitment. Perceived advantages of ePortfolios in recruitment included showcasing key skills/work; ability to comprehensively assess and differentiate between candidates quickly; and accessibility. The main disadvantages were the time taken to review, excessive information and establishing authenticity. Recommended ePortfolios content included samples of professional work, reflections, videos and photos. Inclusion of typical resume content, work experience, skills, transcripts, certificates, references, supervisor evaluations were important, as was a clear and concise structure.

É a afetividade, ou ainda, as modulações sensíveis dos atores do enunciado no conto “O bife e a pipoca” de Lygia Bojunga, demarcando como as diferenças sociais são articuladas no projeto enunciativo do enunciador, que este estudo tem como propósito. Isto é, escolhas enunciativas que recaem sobre o crer do enunciatário, as modalidades epistêmicas, articuladas em percursos figurativos e temáticos que reforçam uma leitura sensorial na busca pela adesão afetiva do leitor. Para ancorar teoricamente a análise, recorremos à Semiótica Discursiva, de linha francesa, no que tange ao estudo do plano de conteúdo, e à Semiótica Tensiva para tratar dos afetos, no estudo dos sentidos depreendidos no conto. Por fim, a partir dos operadores de triagem e mistura, o estudo busca enfatizar como a obra retrata a distinção de classes sociais e, por conseguinte, a exclusão social.

In conjunction with computational density functional theory approaches (DFT), prepared samples were characterized by UV/Vis spectrophotometric studies and Fourier transform infrared measurements (FTIR) to take into account a detailed description of the different reaction mechanisms within the polymeric matrices. To conduct all calculations, the Becke three-parameter hybrid functional (B3LYP) correlation function used with the electron core potential basis set LANL2DZ was used. A detailed study for different reaction regimes was studied and reaction via Oxygen was observed to be preferred and compatible with that of the experimental data. UV/vis. Absorption experimental data were used to calculate the optical energy gap using the Mott-Davis equation and observed data was found to follow an indirect transition route.

Background: The radical cure of Glioblastoma multiforme (GBM) is a troublesome medical problem, owing to its resistance to temozolomide chemotherapy and very poor surgical results or high relapse rate. Resistance to temozolomide emerges from numerous signalling pathways that are altered in GBM, especially the hedgehog signalling pathway. Hence, further research is urgent needed to identify more effective treatment modalities. Methods: We evaluated the effect of ATO on viability, cell proliferation, colony formation production. Flow cytometer assesses the degree of apoptosis, and Western blot analysis the expression of hedgehog signalling pathway proteins(Gli1, Gli2 and SMO). Moreover, use database(CGGA and TCGA) to inquire the relationship between Arrb1 expression level and miR-326 expression level in different levels of gliomas. Finally, The methylation sequencing level of CpG in Arrb1 gene with the survival period of nude mice gives a good explanation to the results of the Immunohistochemica.Results: Flow cytometer showed that the ATO caused apoptosis increased in a dose-dependent manner. Western blot analysis revealed the low expression of Gli1, Gli2 and SMO as well as the mRNA levels(included FOXM1). Arrb1 expression level was positively related with miR-326 expression level in different levels of gliomas from databases(CGGA and TCGA). Immunohistochemical analysis showed that ATO downregulated the expression of SMO, GLI1and Arrb1. The methylation level of CpG in Arrb1 gene was significantly reduced and the survival period of nude mice was prolonged by ATO. Conclusion: Our results showed that the cytotoxicity of ATO could be regulated by the SMO via Hh signalling pathway as well as miR-326, presenting a promising potential therapy for patients with GBM.

Green innovation is a key component of sustainable development amid the fast transition to a low-carbon world. As the most populous country in the world, China displays apparent disparity of green innovation across regions. The extant literature mainly conducted a single factor research on the impact of green innovation and come to conflicting results. Therefore, this study aims to systematically investigate the antecedent multi-factor mechanisms contributing to high green innovation performance.We make the initial attempt to employ a clear-set qualitative comparative analysis(QCA) method to conduct a multi-factor configuration analysis with a sample of 30 provinces and autonomous regions in China. Different from the traditional quantitative regression analysis, this study analyzes 7 conditions jointly to explore the underlying configurations mechanism of green innovation. The results reveal 3 driving configurations for high green innovation performance: resource-driven, policy-dependent and environment-friendly. And the results further suggest that: First, innovation resources ensure the development of green innovation ,and high green innovation performance depends on the richness of innovation resources; Second, environmental regulation serves as a key condition to improve green innovation in the regions with high investment in green innovation and strong government support, and the policy support and effective government guidance are the guarantees for green innovation; Third, the quantity of inter-provincial R&D technology spillovers or foreign investment is the driving force for green innovation in the regions with strong social responsibility. This study takes into consideration of multi-factors that may affect green innovation to address the potential causal relationships, which overcomes the inconsistency in previous single-factor research. The findings shed light on the feasible paths for managers to improve firms’ high green innovation performance in practice.

Analysis of temporal patterns of high-dimensional time-series water quality data is essential in informing better pollution management. In this study, Dynamic Factor Analysis (DFA) and Cluster Analysis (CA) were adopted to analyze time-series water quality data monitored at five stations SB1, SB2, SB3, SB4 and SB5 on La Buong river in the Southern Vietnam. Application of DFA identified two temporal patterns in SB1 and SB2 and three temporal patterns in SB3, SB4 and SB5. Analysis of factor loadings of water variables revealed run-off-driven patterns with the contribution of Total Suspended Solid (TSS), turbidity or Fe at all stations. The association of other variables like BOD5, COD at SB1, SB2, SB4, and SB5 to this run-off pattern exposed their sharing of common driver. On the contrary, separation of variables like Phosphate (PO43−) in SB3, SB4 and SB5 from run-off pattern suggested their local point-source origin. The derived factors from DFA were later used in time-point CA to explore temporal distribution of pollution intensities. Comparisons between clusters’ value and two regulatory benchmarks A2 and B1 for drinking and irrigation water respectively suggested land-use approach for abating TSS, Fe and BOD5, COD at most sites. The control of point sources of BOD5 and COD pollutants is needed at SB3 along with PO43−, Ammonium (NH4+) and Escherichia coli (E.coli) at SB1 and SB4.

Multidrug-resistant (MDR) Klebsiella pneumoniae (K. pneumoniae) poses a serious public health threat. K. pneumoniae strains that produce extended-spectrum beta-lactamases (ESBL) are becoming increasingly reported in nosocomial and community-acquired infections. Besides resistance genes, integrons, and plasmids, altered membrane permeability caused by porin loss and energy-dependent efflux have also contributed to antibiotic resistance in K. pneumoniae. The objective of this study was to determine the correlation between the reduction of antibiotic susceptibility and overexpression of efflux pump as well as the lack of outer membrane proteins (OMPs) among clinical ESBLs resistant K. pneumoniae. The expression levels of ramA, acrA, ompK35 and ompK36 in 12 MDR K. pneumoniae strains with varying MICs levels were analyzed using quantitative real time-Polymerase Chain Reaction (qRT-PCR). The role of efflux pump on antibiotic resistance was also studied by using minimum inhibitory concentration (MICs) method with//without efflux pump inhibitor. The result indicated that the strains with highest resistance to cefotaxime showed the lowest level of ompK35 and ompK36 genes expression while the strains with lowest MIC level of resistance to cefotaxime showed the highest level of expression of acrA and ramA. Our finding also revealed the effect of efflux pump inhibitor phenyl-arginine-b-naphthylamide (PAβN) on the MIC levels of ceftazidime, amoxicillin-clavulanate and cefotaxime which were significantly reduced around 1–7 folds MIC levels. These results suggest that Efflux pump system and deficiently of OMPs contributing role in antibiotic susceptibility which should be taken seriously to prevent the treatment failure due to antimicrobial resistance.

Background: To provide an overview of the worldwide association between hospital beds, the burden of non-communicable diseases (NCDs), and COVID-19 mortality.Methods: Data was extracted regarding COVID-19 deaths and cases from the Our World in Data as of March 23, 2021. The following data was obtained:1) NCDs disability-adjusted life years (DALYs), health-adjusted life expectancy, and the health access and quality index from the Global Burden of Disease study; 2) the number of hospital beds, physicians, nurses and midwives per population, and out-of-pocket payments from the WHO website. Using the multilevel generalized linear model, these variables’ independent associations with COVID-19 mortality rate ratio (MRR) was examined.Results: Hospital beds were associated with reduced COVID-19 mortality (MRR=0.47; 95% CI: 0.44 to 0.5) globally. During COVID-19 peak periods, despite a decreasing trend in COVID-19 MRR with increasing beds in high-income countries, the odds of mortality remained high even within the highest percentile of hospital beds (MRR=1.54 for 20th-40th and 1.06 for >60th bed percentile, respectively). On the contrary, in middle-income countries, an inverse association was observed between the number of hospital beds and COVID-19 mortality in both periods. NCD DALYs were associated with increased COVID-19 deaths, particularly during peak mortality periods in high-income countries. Death-to-case ratio increased by approximately two times during the peak vs non-peak mortality periods.Conclusions: COVID-19 is a syndemic interacting with non-communicable diseases and not only a pandemic. A comprehensive national healthcare plan against COVID-19 spread should include adequate measures to protect vulnerable patients with pre-existing chronic conditions.
