Modelo e heurística matemática híbrida para o problema da recuperação de malha aérea
Authors: De Souza Morais Fábio Emanuel , Gualda Nicolau Dionísio Fares , Caetano Daniel Jorge 
Published: November 2021

O problema de recuperação de malha aérea surge quando eventos inesperados como tempestades, fechamento de aeroportos e manutenção não programada de aeronaves provocam atrasos e/ou cancelamento de voos, inviabilizando o cumprimento da programação original da aeronave. Este trabalho inicia pela apresentação de um modelo matemático para a recuperação da programação de uma empresa aérea. Devido à natureza NP-Hard do problema, o modelo matemático não é capaz de resolver grandes instâncias. Tal circunstância levou ao desenvolvimento de uma heurística matemática composta por dois modelos: um modelo de fluxo em rede com programação inteira mista para gerar uma nova programação com o menor número de cancelamentos e atrasos de voos; e um modelo de programação linear inteira para minimizar as trocas de aeronaves associadas aos voos com relação à programação original. São apresentadas aplicações da heurística a instâncias com até 470 voos, para as quais se obtém, em menos de um minuto de processamento, soluções que distam menos de 0,5% das soluções ótimas, o que permite concluir que a heurística se qualifica para aplicações em casos reais de magnitude considerável.

Published: November 2021

The thermogravimetric behaviors and the kinetic parameters of uncatalyzed and catalyzed pyrolysis processes of a mixture of powdered raw rice husk (RRH) and its ash (RHA) in the form of pellets were determined by thermogravimetric analysis at three different heating rates, i.e., 5, 10, and 20 K/min, from 303 to 873 K. This research aimed to prove that the rice husk ash has a catalytic effect on rice husk pyrolysis. To investigate the catalytic effect of RHA, rice husk pellets (RHP) with the weight ratio of RRH:ARH of 10:2 were used as the sample. Model-free methods, namely Friedman (FR), Kissinger-Akahira-Sunose (KAS), and Flynn-Wall-Ozawa (FWO), were used to calculate the apparent energy of activation(EA). The thermogravimetric analysis showed that the decomposition of RHP in a nitrogen atmosphere could be divided into three stages: drying stage (303-443 K), the rapid decomposition stage (443-703 K), and the slow decomposition stage (703-873 K). The weight loss percentages of each stage for both uncatalyzed and catalyzed pyrolysis of RHP were 2.4-5.7%, 35.5-59.4%, and 2.9-12.2%, respectively. Using the FR, FWO, and KAS methods, the values of for the degrees of conversion (a) of 0.1 to 0.65 were in the range of 168-256 kJ/mol for the uncatalyzed pyrolysis and 97-204 kJ/mol for the catalyzed one. We found that the catalyzed pyrolysis led the to have values lower than those got by the uncatalyzed one. This phenomenon might prove that RHA has a catalytic effect on RHP pyrolysis by lowering the energy of activation.

»I sat alone«. The Language of Loneliness in the Hebrew Bible
Authors: Hildebrandt Samuel 
Published: November 2021

Abstract
The Hebrew Bible frequently portrays lonely characters and voices, yet a specific study of »loneliness« is not yet available. As a basic semantic and exegetical inquiry, this article surveys the usage of the lexeme בד/בדד and analyses four passages in which the expression »sitting alone« (בדד + ישׁב) appears, namely, Lev 13:46, Jer 15:17, Lam 1:1 and 3:28. Of key interest are the literary environment and discourse structures in which בדד + ישב stands. The characterisation and evaluation of loneliness likewise receive some attention. The study concludes with a synthesis that highlights connections between loneliness, society, God, and death.
Music in the Protagonist’s World, the Protagonist in the World of Music: Liudmila Ulitskaya: The Big Green Tent
Authors: Szabó Tünde 
Published: November 2021

The article examines the musical component in L. Ulitskaya’s novel The Big Green Tent. The first part provides an overview of those musical elements – realities, prototypes of individual characters and pretexts with musical themes, with the help of which an autonomous world and the image of one of the main characters of the work are created. The second part analyzes a fragment of the novel, which mixes musical and literary principles of text organization and creates a multidimensional connection with S. Rakhmaninoff's Symphonic Dances. The analysis shows that the musical component in Ulitskaya's novel performs a double function – constructing one of the plot lines and musicalizing certain fragments of the text.
The Image of the Trickster in the Novel by Vladimir Makanin The Underground, or the Hero of Our Time
Authors: Kovtun Natalia 
Published: November 2021

The article is devoted to the study of the image of the trickster – one of the key ones in modern Russian culture and literature. The article analyzes the specifics of the functioning and attribution of the trickster figure in V. Makanin‘s novel The Underground, or the Hero of Our Time (1998). This is a soliloquium novel. It is shown how the appearance of the trickster hero, who is aware of his connection with the myth, helps to solve the tragic issues facing the consciousness of the turn of the XX-XXI centuries. The life – affirming, vital potential of the image of the main character of the novel – Petrovich is considered, the inherent possibilities, means of awareness and representation of the tragic are revealed. The paper examines the intertextual field of the character’s image, including the archetypes of “naked man”, “little man”, “extra man” and “underground man”, who made up the canon of Russian classics. The reinterpretation of archetypes is the realization of the author’s attempt, his hero, to “push” Russia into the next century, free from the dictates of the literary canon, opening up the prospect of finding one’s own Word as a self-determination of an individual in the new century.
Interpretation of History in the Contemporary Lithuanian Essayistics
Authors: Meržvinskaitė Birutė 
Published: November 2021

The article discusses the peculiarities of the representation of history in Sigitas Parulskis’s essay collection Eternity does not move me (2018). The essay as genre in this book unites subjectivity, critical and ironic mode of narration and the conventional categories of historiographical analysis (the state, religion, society, collective identity, culture). Explanation on the ambivalent sense and relationship between literary imagination and historical facticity is done to prove the New Historicism slogan “the historicity of texts and the textuality of history”.
Article Comments: Is This Truly Feedback for Editorial Boards? Views and Experiences of Journalists
Authors: Mažylė Jolanta 
Published: November 2021

In the modern society, online comments, especially comments on news websites, create a new problem: in theory, they should guarantee the freedom of speech and improve the work of editorial boards of daily newspapers (news websites). Feedback helps the media to better understand readers and their needs. The essence of feedback for the journalist is to obtain additional information in order to expand the topic of the article, to explore new aspects of the researched subject and to react promptly to relevant information received from the audience. Exploratory research was carried out in May 2021 striving to analyse how much actual feedback works when a media outlet publishes reader comments, as well as to examine how media staff evaluate the necessity of commends under articles and their value for direct work. Fifteen professional journalists – who have more than four years of journalistic experience in national, regional and local media – participated in the research.
Research participants were asked 9 questions, of which only several were closed-ended, while the rest were open-ended. The survey was thus carried out in person, seeking to ascertain the questions discussed and clarify situations or circumstances. The duration of each interview was 45-80 minutes. Meetings took place with interviewees or they were contacted via Skype and ZOOM platforms.
The article discusses research results, provides examples from editorial experience, as well as reveals views of editorial boards and journalists concerning the phenomenon in question and its problematic aspects.

Published: November 2021

BACKGROUND
In September 2017, the American Academy of Pediatrics issued guidance recommending hepatitis B vaccine be administered to well newborns with birth weight ≥2000 g within 24 hours after birth. At that time, ∼85% of well newborns were vaccinated before discharge at our center; however, only 35% were vaccinated within 24 hours after birth. Our aim was to vaccinate 70% of eligible newborns within 24 hours after birth by June 2018 while maintaining the overall rate of vaccination.

METHODS
A multidisciplinary improvement team analyzed existing vaccine administration processes in the well-newborn nursery. From October 2017 to January 2018, changes were made to activation of vaccine orders and to obtaining and documenting the consent processes. Vaccine administration was bundled with routine care given ≤24 hours after birth, and parent scripting was changed from offering vaccine as an option to stating it as a recommendation. From November 2016 to June 2019, we determined the overall rate and timing of vaccination using statistical process control methods.

RESULTS
Among 10 887 eligible infants, the proportion administered hepatitis B vaccine ≤24 hours after birth increased from 35.5% to 78.8% after process changes with special-cause variation on process control charts. Proportion of infants receiving vaccine any time before discharge also increased from 86.5% to 92.3%.

CONCLUSIONS
Specific process changes allowed our birth center to comply with the recommended timing for hepatitis B vaccination of ≤24 hours after birth among eligible newborns.

Authors: Uong Audrey M. , Cabana Michael D. , Serwint Janet R. , Bernstein Carol A. , Schulte Elaine E. 
Published: November 2021

OBJECTIVES
To examine the impact of the coronavirus disease 2019 (COVID-19) pandemic and associated workflow changes, such as deployment on pediatric faculty burnout in an early epicenter of the pandemic. We hypothesized burnout would increase during the COVID-19 surge.

METHODS
We conducted serial cross-sectional surveys of pediatric faculty at an academic, tertiary-care children’s hospital that experienced a COVID-19 surge in the Northeastern United States. Surveys were administered pre-surge (February 2020), during the surge (April 2020), and postsurge (September 2020). The primary outcome was burnout prevalence. We also measured areas of worklife scores. We compared responses between all 3 survey periods. Continuous variables were analyzed by using Student’s t or Mann–Whitney tests, and categorical variables were analyzed by using χ2 or Fisher’s exact test, as appropriate.

RESULTS
Our response rate was 89 of 223 (40%) presurge, 100 of 267 (37%) during the surge, and 113 of 275 (41%) postsurge. There were no differences in demographics, including sex, race, and academic rank between survey periods. Frequency of burnout was similar in all 3 periods (20% to 26%). The mean scores of emotional exhaustion improved during the surge (2.25 to 1.9; P = .04).

CONCLUSIONS
Contrary to our hypothesis, we found no changes in pediatric faculty burnout after a COVID-19 surge. Emotional exhaustion improved during the COVID-19 surge. However, these findings represent short-term responses to the COVID-19 surge. Longer-term monitoring of the impact of the COVID-19 surge on pediatric faculty burnout may be necessary for health care organizations to mitigate burnout.

Published: November 2021

OBJECTIVES
Clinical event debriefing (CED) can improve patient care and outcomes, but little is known about CED across inpatient settings, and participant experiences have not been well described. In this qualitative study, we sought to characterize and compare staff experiences with CED in 2 hospital units, with a goal of generating recommendations for a hospital-wide debriefing program.

METHODS
We conducted 32 semistructured interviews with clinical staff who attended a CED in the previous week. We explored experiences with CED, with a focus on barriers and facilitators. We used content analysis with constant comparative coding to understand priorities identified by participants. We used inductive reasoning to develop a set of CED practice recommendations to match participant priorities.

RESULTS
Three primary themes emerged related to CED barriers and facilitators. (1) Factors affecting attendance: most respondents voiced a need for frontline staff inclusion in CED, but they also cited competing clinical duties and scheduling conflicts as barriers. (2) Factors affecting participant engagement: respondents described factors that influence participant engagement in reflective discussion. They described that the CED leader must cultivate a psychologically safe environment in which participants feel empowered to speak up, free from judgment. (3) Factors affecting learning and systems improvement: respondents emphasized that the CED group should generate a plan for improvement with accountable stakeholders. Collectively, these priorities propose several recommendations for CED practice, including frontline staff inclusion.

CONCLUSIONS
In this study, we propose recommendations for CED that are derived from first-hand participant experiences. Future study will explore implementation of CED practice recommendations.

Aim. To study the prevalence of RBM20 gene polymorphisms and their relationship with the structural and functional left atrial (LA) characteristics in patients with coronary artery disease and heart failure with reduced ejection fraction (HFrEF).Material and methods. The study included 138 men aged 55,8±6,6 years with prior myocardial infarction ³12 months ago and HFrEF (class II-IV heart failure, left ventricular ejection fraction (Simpson’s methods), 25,1±7,2%). The control group consisted of 384 healthy donors. Genotyping of two RBM20 polymorphic variants (rs942077 and rs35141404) was performed by real-time polymerase chain reaction.Results. The prevalence of RBM20 polymorphisms did not differ in the HFrEF cohort and the control group. The GA rs35141404 genotype was more common among patients with a less pronounced increase in LA volume index (LAVI) (p=0,034). The minor A allele rs35141404 was associated with a protective effect on severe LA remodeling. However, this association did not reach the level of significance.Conclusion. For the rs942077 and rs35141404 polymorphic variants of the RBM20 gene, no significant associations were found with the LA size and atrial fibrillation presence in patients with HFrEF and old myocardial infarction. There was a tendency towards the association of the A allele and the GA rs35141404 genotype with a protective effect on LA remodeling. The data obtained confirm the need for further search for genotype-phenotype relationships of a wider population of patients with heart failure and coronary artery disease.

The aim of this study was to investigate the patient characteristics and laboratory parameters for COVID-19 non-survivors as well as to find risk factors for major bleeding complications. For this retrospective study, the data of patients who died with COVID-19 in our intensive care unit were collected in the period of March 20 - April 30, 2020. D-dimer, platelet count, C-reactive protein (CRP), troponin, and international normalized ratio (INR) levels were recorded on the 1st, 5th, and 10th days of hospitalization in order to investigate the possible correlation of laboratory parameter changes with in-hospital events. A total of 161 non-survivors patients with COVID-19 were included in the study. The median age was 69.8±10.9 years, and 95 (59%) of the population were male. Lung-related complications were the most common in-hospital complications. Patients with COVID-19 had in-hospital complications such as major bleeding (39%), hemoptysis (14%), disseminated intravascular coagulation (13%), liver failure (21%), ARDS (85%), acute kidney injury (40%), and myocardial injury (70%). A multiple logistics regression analysis determined that age, hypertension, diabetes mellitus, use of acetylsalicylic acid (ASA) or low molecular weight heparin (LMWH), hemoglobin, D-dimer, INR, and acute kidney injury were independent predictors of major bleeding. Our results showed that a high proportion of COVID-19 non-survivors suffered from major bleeding complications.
Musineon glaucescens (Apiaceae), a new species from Central Montana, U.S.A.
Authors: Lesica Peter 
Published: November 2021

Musineon glaucesens is described as a new species from two populations in the Big Belt Mountains of Montana, U.S.A. It appears to be most closely allied to the small genus Musineon which is endemic to western North America. It occurs just outside the range of M. vaginatum but differs from that species by its larger fruits, more widely lobed and glaucous leaves, and talus-slope habitat.
A morphological comparison of Arceuthobium abietinum and A. campylopodum (Viscaceae) and nomenclatural changes for A. abietinum
Authors: Mathiasen Robert L. , Kenaley Shawn C. 
Published: November 2021

Fir dwarf mistletoe (Arceuthobium abietinum, Viscaceae) parasitizes true firs (Abies spp.) in the Pacific Northwest through California, the Southwest, and into northern Mexico. At present, fir dwarf mistletoe consists of two special forms (formae speciales, f. sp.) and one subspecies that are morphologically similar, but exhibit a high degree of host specificity. However, A. abietinum has been treated as a subspecies of A. campylopodum or conspecific with it in some taxonomic treatments. Therefore, we undertook this study to compare the morphologies of these dwarf mistletoes; collecting morphological data from nearly 100 A. abietinum and 60 A. campylopodum populations collected across most of their geographic ranges and analyzing these data using univariate and multivariate statistical tests. Our results demonstrated that the special forms and subspecies of A. abietinum are morphologically distinct from A. campylopodum, thereby, supporting the continued recognition of A. abietinum as a separate species. Furthermore, our analysis found significant differences for several of the characters we examined between the special forms of A. abietinum. Therefore, we recombined the special forms as subspecies: A. abietinum subsp. abietinum (formerly f. sp. concoloris) and A. abietinum subsp. magnificae (formerly f. sp. magnificae). The previously described A. abietinum subsp. wiensii was morphologically distinct from subsp. abietinum and subsp. magnificae. The distinctiveness of these taxa was supported by their host affinities as well.
Calathea multispicata (Marantaceae), a new species endemic to Colombia
Authors: Kennedy Helen , Serna Marcela 
Published: November 2021

Calathea multispicata H. Kenn. & M. Serna, endemic to Colombia, is described as new. Currently, it is known only from the Department of Valle de Cauca in premontane (1300–1800 m) pluvial forest habitat. Calathea multispicata is characterized by the presence of only two leaves per shoot, one basal and one cauline and the numerous relatively small, short-pedunculate inflorescences. Each inflorescence has 3–4 bracts, which, after the first terminal one, are borne in the axil of the cauline leaf. Calathea multispicata is most similar in aspect to C. harlingii H. Kenn. Calathea multispicata shares the habit of a single cauline leaf subtending inflorescences above one or more basal leaves with C. harlingii, C. hagbergii H. Kenn, C. andersonii H. Kenn. and C. pluriplicata H. Kenn. but differs from these species in having a single vs. 2–10 basal leaves, more numerous (up to 19 vs. 2–7) inflorescences with fewer bracts (3–4 vs. 5–17) borne in a series in the axil of the cauline leaf.

Published: November 2021

Rehderodendron truongsonense, a new species from Vietnam, is described and illustrated. In the treatment of the Styracaceae for the Flore du Cambodge, du Laos, et du Viêtnam, specimens of this species were recognized as R. macrocarpum Hu. These specimens clearly differ from R. macrocarpum, however, as well as from all other species of Rehderodendron (where these characters are known) by, e.g., an evergreen versus deciduous habit, fewer secondary veins of the leaf blade, shorter inflorescences and corolla lobes, large and conspicuous lowermost bracteoles, the presence of eight ovules per carpel, and a fruit with ca. 10 to 20 ribs that are indistinct. Phylogenetic analysis based on five chloroplast DNA regions (clpP-psbB, ndhD-psaC-ndhE-ndhG, rpl22-rps19, rps18-rpl20, and psbI-trnS-GCU) placed the new species as nested within Rehderodendron and sister to R. gongshanense. This new species is endemic to the Truong Son Mountain Range, from which the epithet is derived, and we assign it an IUCN Red List preliminary status as Near Threatened.
