Authors: Mobini Maryam , Ghasemian Roya , Vahedi Larijani Laleh , Mataji Maede , Maleki Iradj
Published: October 2021

Background:

The cause of coronavirus disease 2019 (COVID-19) is a virus which can lead to severe acute respiratory syndrome-CoV-2 (SARS-COV-2). There are evidences of involvement of immune system in pathogenesis of this disease. We investigated the presence of various vasculitis-associated autoantibodies and complement levels in patients with COVID-19.

Materials and Methods:

Patients with severe or critical type of COVID-19 were evaluated for symptoms, signs, and laboratory tests of vasculitis syndromes including rheumatoid factor (RF), antinuclear antibody (ANA), anti-double-stranded DNA, c and p anti-neutrophilic cytoplasmic antibody (c ANCA and P ANCA), and complement levels.

Results:

The study was performed in forty patients with severe or critical illness. The mean age of the participants was 48.5 ± 9.8 years. All patients had pulmonary involvement in lung computed tomography scans. Vasculitis laboratory test results included RF in two patients, ANA in three patients, and ANCA in one patient. Seventeen (42.5%) patients had hypocomplementemia in one or more complement tests. Four patients expired, of whom three had a decrease in complement level.

Conclusion:

Decrease in complement levels may predict a critical state of COVID-19 disease. Therefore, measuring its levels may be of great benefit in making earlier decisions to initiate disease-suppressing treatments including corticosteroids.

Background:

Familial hypercholesterolemia (FH) leads to elevated low-density lipoprotein cholesterol (LDL-C) levels in plasma. Mutations of its related gene; apolipoprotein B (APOB) is seen in about two percent of the patient with FH. Thyroid disease is usually part of the exclusion criteria for the detection of FH which alters the lipid profile. We evaluated mutations in the APOB gene in patients with high LDL-C levels.

Materials and Methods:

Patients aged between 2 and 80 years with at least one LDL-C level of more than 190 mg/dl were selected (120 patients) from Isfahan Laboratories. Blood samples were obtained from all patients. Genomic DNA was extracted. Primer sequences were designed by Oligo 7.60 to amplify the desired 844 bp region of exon 26 of the APOB gene containing R3500Q and R3500W variants associated with FH.

Results:

Overall, two patients showed a heterozygous form of a common pathogenic variant in exon 26 named c. 10579 C > T (R3500W, cDNA.10707), and one patient was hypothyroidism. We also recognized another nonpathognomonic variant c. 10913G > A (rs1801701, cDNA.11041) in 13 patients, two of them were hypothyroidism.

Conclusion:

This study for the first time shows the coexistence of APOB mutation in hypothyroidism, which emphasis screening of patients with hypothyroid for FH detection.

Effects of exposure to ambient air pollution on pulmonary function impairment in Korea: the 2007-2017 Korea National Health and Nutritional Examination Survey
Authors: Choi Soo Beom , Yun Sungha , Kim Sun-Ja , Park Yong Bum , Oh Kyungwon
Published: October 2021

OBJECTIVES: This study aimed to investigate the association between pulmonary function and air pollution using 2007-2017 data from the Korea National Health and Nutrition Examination Survey, a nationwide cross-sectional representative survey.METHODS: A total of 27,378 participants that had sampling weights from a complex sample survey were included in this study. Using the data for forced expiratory volume in 1 second and forced vital capacity, the participants with pulmonary function impairment were classified according to the criteria of restrictive lung disease and chronic obstructive pulmonary disease (COPD). Exposure to ambient air pollution was estimated using the Community Multiscale Air Quality model. Multivariate linear and logistic regression analyses with complex samples were used to determine the associations between pulmonary function and air pollution after adjusting for covariates.RESULTS: In total, 13.2% of the participants aged >40 years had COPD, and 10.7% were classified as being in the restrictive lung disease group. According to the multivariate logistic regression model, the odds ratios for the fourth quartiles of particulate matter less than 10 μm in diameter (PM10), particulate matter less than 2.5 μm in diameter (PM2.5) and carbon monoxide (CO) with a 2-year lag period were 1.203 (95% confidence interval [CI], 1.036 to 1.396), 1.283 (95% CI, 1.101 to1.495), and 1.292 (95% CI, 1.110 to 1.504), respectively, using the restrictive lung disease group as an event after adjusting for covariates in the complex sample.CONCLUSIONS: Long-term exposure to PM10, PM2.5, and CO was significantly associated with pulmonary function, especially restrictive lung disease.

Published: October 2021

Aedes albopictus is a competent vector of numerous pathogens, representing a range of transmission cycles involving unique hosts. Despite the important status of this vector, variation in its feeding patterns is poorly understood. We examined the feeding patterns of Ae. albopictus utilizing resting collections in Long Island, NY, and contextualized blood meal sources with host availability measured by household interviews and camera traps. We identified 90 blood meals, including 29 humans, 22 cats, 16 horses, 12 opossums, 5 dogs, 2 goats, and 1 each of rabbit, rat, squirrel, and raccoon. This is only the third study of Ae. albopictus blood feeding biology that quantitatively assessed domestic host availability and is the first to do so with wild animals. Host feeding indices showed that cats and dogs were fed upon disproportionately often compared with humans. Forage ratios suggested a tendency to feed on cats and opossums and to avoid raccoons, squirrels, and birds. This feeding pattern was different from another published study from Baltimore, where Ae. albopictus fed more often on rats than humans. To understand whether these differences were because of host availability or mosquito population variation, we compared the fitness of New York and Baltimore Ae. albopictus after feeding on rat and human blood. In addition, we examined fitness within the New York population after feeding on human, rat, cat, horse, and opossum blood. Together, our results do not indicate major mosquito fitness differences by blood hosts, suggesting that fitness benefits do not drive Northeastern Ae. albopictus feeding patterns.

Published: October 2021

Schistosomiasis is the second most important parasitic infection after malaria in terms of its socioeconomic impact and is endemic in 78 countries. It affects more than 240 million people worldwide, with 90% of cases occurring in sub-Saharan Africa. In Uganda, Schistosoma mansoni is the most common species, with more than seven million people infected and 17 million living at risk despite mass drug administration (MDA) of praziquantel initiated more than 16 years ago. There has been a shift in the WHO schistosomiasis goals from controlling morbidity to elimination as a public health problem. Understanding the drivers of infection in persistent transmission hotspots despite ongoing control interventions is paramount. We conducted a cross-sectional epidemiological study of 381 individuals in Bugoto community, Mayuge district, Eastern Uganda, along with a structured survey to ascertain drivers of S. mansoni infection. Bugoto has had community-wide MDA since 2004. We detected a S. mansoni prevalence of 52% across the whole community and a prevalence of 71% in school-age children. This qualifies Bugoto as a highly endemic community according to WHO guidelines. Using a multivariate logistic regression, we found that S. mansoni infection was best explained by age group, longer residence times, and any daily contact with lake water. Schistosoma mansoni infection remains a large burden across this community. This study identifies opportunities for interventions that reduce lake water contact, expand treatment eligibility to all at risk, and improve MDA coverage for long-term residents in these settings to control schistosomiasis in persistent transmission hotspots.

Research mentoring programs are limited in many low- and middle-income countries (LMICs). The TDR Global initiated a global crowdsourcing open call soliciting proposals on how to improve research mentorship in LMICs. The purpose of this study is to examine ideas submitted to this open call to identify the ways to improve research mentorship in LMICs. Open calls have a group of individuals solve all or part of a problem and then share solutions. A WHO/TDR/SESH crowdsourcing guide was used to structure the open call. Each submission was judged by three independent individuals on a 1–10 scale. Textual submissions were extracted from eligible proposals and qualitatively analyzed via inductive and deductive coding techniques to identify themes. The open call received 123 submissions from 40 countries in Asia (49), Africa (38), Latin America (26), and Europe (10). Among all participants, 108 (87%) had research experience. A total of 21 submissions received a mean score of 7/10 or higher. Our thematic analysis identified three overarching themes related to prementoring, facilitation, and evaluation. Prementoring establishes mentor–mentee compatibility to lay foundations for mentorship. Facilitation involves iterative cycles of planning, communication, and skill improvement. Evaluation creates commitment and accountability within a framework of monitoring. This global crowdsourcing open call generated numerous mentorship ideas, including LMIC-contextualized facilitation tools. The open call demonstrates a need for greater focus on mentorship. Our data may inform the development of formal and informal mentoring programs in LMIC settings.
Nagrobek Stanisława Staszica a polityka wizerunkowa Towarzystwa Warszawskiego Przyjaciół Nauk

Stanisław Staszic’s Tombstone and the Image-Building Policy of the Warsaw Society of Friends of Sciences

The article is devoted to the artistic setting of Stanisław Staszic’s (1755–1826) burial place, for which his main heir, the Warsaw Royal Society of the Friends of Sciences (TKWPN), was responsible. The inspiration to raise this topic was the discovery of two previously unknown Jakub Tatarkiewicz’s designs of Staszic’s unrealized neoclassical tombstone in the collections of the Central Archives of Historical Records in Warsaw (AGAD). However, the projects were never commissioned by TKWPN but were the sculptor’s proposal. By analysing the relationship between these artistic projects and the initiatives concerning Staszic’s tomb which stemmed directly from the Society (a big raw stone as memorial), the article highlights the problem of TKWPN’s participation in creating the posthumous cult of its long-time president and most important benefactor. The TKWPN’s seemingly paradoxical reluctance to glorify Staszic by means of traditional (artistic) forms of commemoration can be interpreted as a logical action calculated to benefit the Society’s image. Therefore, focusing on this single aspect of the posthumous cult of Staszic, directly related to the TKWPN, this article refers to the image-building policy of this institution, and thus to the ways of building its social status. At the same time, it tackles the issue of the prestige of science and scientific patronage as a new (from the early 19th-century perspective) form of public merit.
Czas kolejowy

Railway Time The inventions of the electromagnetic telegraph and the railroads significantly accelerated communication in time and space. It greatly influenced the way time was expressed and forced a change of centuries-old patterns and habits. It became necessary to gradually move away from local times (the average solar times of individual places) to the uniform time in the scale of entire countries, and then to the zone time. This process began in the 1830s on the railway and a few years later in the telegraph service, developing in parallel and in conjunction with the railroads. Initially, individual railway authorities adopted the same railway time on their networks (usually the capital time of a given country or the directorate’s headquarters). From 1884 until the first decade of the 20th century, culminating in the early 1990s, they gradually switched to zone time. Its introduction improved the work of railways, increased traffic safety, and made it easier for passengers to find their way around train timetables. Almost in parallel, since the mid-1860s, the process of switching from a twelve-hour count to a 24-hour count of time on the railways took place. In the rich literature devoted to time in its various aspects, few studies focus on the issues of organizing the measurement and expression of time on railways, and there are virtually no studies relating to railways in the present-day Polish lands which at the time operated under three different state authorities. The work aims to collect and systematize the facts that contributed to the process of introducing the 24-hour zone time on Central European railways and to present this process in the context of the world railways.

Stanisław Siedlecki’s (1912–2002) Film Portraits against the Backdrop of Svalbard. Vignettes from the Visual History of Science The article offers a new perspective on Stanisław Siedlecki’s biography through visual history, with a particular emphasis on film history. The connections between Siedlecki’s life and the cinema can be grouped in three sections: 1. films starring Siedlecki, 2. films by Siedlecki and 3. films about Siedlecki. The film Do Ziemi Torella (To Torell Land) represents the pre-war period; the post-war period is marked by Siedlecki’s collaboration with Jarosław Brzozowcki on the making of Skroplone Powietrze (Liquefied Air) and Wieliczka – both from 1946. In the International Geophysical Year 1957/1958, Siedlecki led the Polish polar expedition, during which the visual material was created. He appeared in all three ‘roles’ (as a co-writer, protagonist, and consultant) in Jarosław Brzozowski’s film W Zatoce Białych Niedźwiedzi (In the Polar Bear Bay). He consulted polar films until the early 1990s. There are also two film biographies (portraits) of Siedlecki by Wanda Rollna and Iwona Bartólewska. The analysis of this material has also shed new light on the visual narration of the Polish polar expeditions in the 20th century.

Press releases as a component of the communication process between journalists and public relations representatives

The article is based entirely on the results of research carried out by a research team composed of experts of the Polish Press Agency and the Institute for Development of Information Society under the scientific direction of the author of the publication. The researchers aimed to examine the role that press releases play in the relations between media representatives and public relations specialists, the extent to which they are used, and the attitude of journalists to this type of material. The research activities were carried out at the turn of August and September 2020 among journalists, including in particular people listed in the Polish Press Agency databases. The research was carried out using a quantitative research method – CAWI technique (Computer Assisted Web Interview). While creating their materials, media representatives seek inspiration in various sources, however, when writing articles they most frequently use press releases sent by e-mail. Such a position was taken by respondents, who work mainly for Web portals.

Artykuł opiera się w całości na wynikach badań zrealizowanych przez zespół badawczy złożony z ekspertów Polskiej Agencji Prasowej oraz Instytutu Rozwoju Społeczeństwa Informacyjnego pod kierownictwem naukowym autora publikacji. Celem było zbadanie, jaką rolę informacja prasowa odgrywa w relacjach pomiędzy przedstawicielami mediów a specjalistami do spraw public relations, w jakim zakresie wykorzystuje się ją i jaki jest stosunek dziennikarzy do tego typu materiałów. Działania badawcze zrealizowano na przełomie sierpnia i września 2020 roku wśród dziennikarzy, w tym przede wszystkim osób znajdujących się w zasobach baz Polskiej Agencji Prasowej. Badania zostały wykonane za pomocą ilościowej metody badawczej przy użyciu techniki CAWI (Computer Assisted Web Interview). Na bazie badań wykazano m.in., że przedstawiciele mediów, tworząc swoje materiały, poszukują inspiracji w różnych źródłach, jednak przy pisaniu artykułów prasowych najczęściej korzystają z informacji prasowych przesyłanych drogą mailową, przy czym istotnie częściej taką deklarację składali ankietowani, którzy pracują głównie w portalach internetowych.

Fear and retrotopia – Critical reflections on the rise of defensive emotions in liquid modernity
Authors: Jacobsen Michael Hviid
Published: October 2021

This article critically addresses the contemporary study of what is called 'defensive emotions' such as fear and nostalgia among a number of social theorists. While it may be true that the collective emotions of fear and nostalgia (here framed by the phrase of 'retrotopia') may indeed be on the rise in Western liberal democracies, it is also important to be wary of taking the literature on the matter as a sign that fear and nostalgia actually permeate all levels of culture and everyday life. The article starts out with some reflections on the sociology of emotions and shows how the early interest in emotions (theoretical and empirical) among a small group of sociologists is today supplemented with the rise of a critical social theory using collective emotions as a lens for conducting a critical analysis of the times. Then the article in turn deals with the contemporary interest within varuious quarters of the social sciences with describing, analysing and diagnosing the rise of what is here called 'defensive emotions' – emotions that express and symbolize a society under attack and emotions that are mostly interpreted as negative signs of the times. This is followed by some reflections on the collective emotions of fear and nostalgia/retrotopia respectively. The article is concluded with a discussion of how we may understand and assess this relatively new interest in defensive emotions.

A lot of people in Korea have suffered from severe toxicity of PHMG, a humidifier disinfectant. To assess the risk and in-depth mechanistic understanding of toxicity posed by a hazardous substance, it is essential to determine its biological uptake in organs. In this study, we investigate the biodistribution of PHMG using radioanalytical techniques. By labeling PHMG with radioactive indium (111In), the uptake values of PHMG in organs can be measured after intravenous injection in Sprague–Dawley rats for up to 168 h. The results indicate that PHMG is distributed in the liver (28.63% injected dose (%ID)) and lungs (12.44%ID) at 30 min post administration. In addition, the clearance rate of PHMG distributed in the internal organs is slow, with approximately 65% of injected PHMG remaining in the lungs after 1 week. Moreover, we quantified biodistribution of the radiolabeled PHMG exposed through intratracheal instillation and oral administration routes, and the observed data were compared to each other to understand in vivo behavior of PHMG. In addition, radiolabeled PHMG in an animal model can be visualized using SPECT/CT. The obtained results indicate that repetitive exposure to PHMG results in damage to lungs, as well as extrapulmonary organs.

Published: October 2021

Dikey eksenli rüzgâr türbinleri; küçük ve estetik yapıda olması, sessiz çalışabilmesi, şehir merkezlerinde ve sosyal alanlarda da sıkça kullanılması sayesinde tercih edilmektedir. Dikey eksenli rüzgâr türbini olan Savonius rüzgâr türbininin düşük olan kanat performansını arttırabilmek için literatürde çeşitli çalışmalar yapılmıştır. Bu çalışmada, kanatlar arasına toplamda aynı yüzey alanına sahip daire, kare, altıgen ve yekpare hava akış kanalı açılmıştır. İncelenen hava akış kanallarından yekpare hava akış kanalının 2,82x10-2 değeri ile en yüksek güç katsayısını verdiği tespit edilmiştir. Yekpare hava akış kanalı türbinin 0,10-0,30 arasında örtüşme oranlarına sahip tasarımları incelenmiş ve 0,25 örtüşme oranının en yüksek güç katsayısını verdiği sonucuna varılmıştır.
Metatalk in Advanced Spanish L2 and Heritage Learners When Solving Lexical Problems: A Multiple-case Study
Authors: Cecilia Tocaimaza-Hatch C.
Published: October 2021

Metatalk (MT) emerges in interaction when learners, working through a linguistic problem, turn their attention to features of their language (Swain, 2000; Swain & Lapkin, 2002). One factor that influences how MT develops is learners’ language proficiency. This multiple-case study explored how high-proficiency Spanish L2 and heritage learners engaged in lexical MT during a text reconstruction activity. Key findings from the analysis of learners’ lexical language-related episodes (LLREs) and commentaries from a debriefing interview revealed that (a) learners targeted mostly word meaning with few exchanges on spelling and pronunciation, (b) LLRE frequencies were comparable among dyads and learner groups, (c) learners described inferencing processes toward solving LLREs as internal and often not verbalized, thus demonstrating a transition toward self-regulation, and (d) although capable of producing MT in Spanish, learners often gravitated toward English in their metalinguistic talk. MT was materialized as dyadic collaboration when learners sought an answer together; role-taking emerged as one partner took the expert role, at least momentarily, and provided an answer to the linguistic question posed by their partner.
Effect of Bay Spacing on Design Parameters of RC Structures Subjected to Lateral Loads
Authors: Vimala A. , Vimala A.
Published: October 2021

Structural configuration is one of the
important parameters to control the
performance of multi-storeyed structures
subjected to lateral loads. On other hand, also
the economy of multi-storeyed structures
depends on the spacing of columns. The
present investigation is aiming to find the
effect of bay spacing on the performance of
medium to high rise RC structures subjected

to lateral loads. In this regard, a computer-
based analysis is carried out for 10, 15, 20, 25

and 30 storied bare frame structures. Each
structure performance under lateral loads is
investigated for 4 types of bay spacing i.e.
5m, 6m, 7.2m and 8.64m, with an increment
of 20% bay space each time. For each
structural model, the behaviour of the
structure is examined in terms of storey
displacement, storey drift and base shear. The
quantitative parametric comparison is done
between all the models mentioned and has
identified the optimal size of the bay spacing
to suit the aspect ratio of the structure is
proposed.

Authors: Бабич А.В. , Остапчук П.Н.
Published: October 2021

Численно (методом конечных разностей) посчитаны диффузионные потоки радиационных точечных дефектов на круговую базисную краевую петлю циркония в тороидальном резервуаре с учетом их упругого взаимодействия и упругой анизотропии гексагонального кристалла. Тороидальная геометрия резервуара представляется более приемлемой для петли, чем сферическая или цилиндрическая, поскольку позволяет провести расчеты для петли любого размера и без какой-либо коррекции упругого поля в ее области влияния. Получены зависимости эффективностей захвата и «bias»-фактора петли от радиуса и ее природы. Показана существенная роль формы граничного условия на внешней поверхности резервуара в нарушении симметрии в поглощении ТД петлями разной природы.

Authors:   Commission for Air Quality Management in NCR and Adjoining Areas, Tyagi Charu
Published: October 2021

The COVID-19 epidemic forced many countries around the world to lockdown completely. This occlusion influenced the atmospheric composition positively due to reduced anthropogenic activities. Recently, many studies across India have shown how the COVID-19 lockdown has affected air quality in different cities. However, these studies did not examine the phased percentage variation in air pollutant concentrations across different states of India. In this study, percentage variation in the concentration of five criteria pollutant, PM10, PM2.5, NO2, CO and Ozone were studied for 13 states across India during four phases of COVID-19 lockdown. A significant decrease in air pollutant levels was observed in all four phases, with phase 1 and phase 2 reporting a maximum decrease. PM10 and PM2.5, CO and NO2 showed a decrease in concentration in all states. Ozone showed a mixed response, with both increase and decrease recorded across states. During the COVID-19 lockdown period in India, AOD levels were reduced by 10.25%. This study will certainly help regulators set the guidelines and mitigation measures for appropriate control of air pollutants in different states in future.

Published: October 2021

This study aims to obtain empirical evidence of the influence of the six elements of fraud hexagon theory on potential financial statement fraud by involving the audit committee which acts as a moderating variable in the financial statements of state- owned companies listed on the Indonesia Stock Exchange in 2016-2020. Potential financial statement fraud is measured using the f-score model. The research sample was obtained by the purposive sampling technique. Data analysis methods and techniques include descriptive statistics, evaluation of the SEM-PLS model, and hypothesis testing. The results show that financial pressure has a positive effect on potential financial statement fraud, effective monitoring has a negative effect on potential financial statement fraud, while related party transactions, CEO education, CEO narcissism, and political connection do not affect potential financial statement fraud. The role of the audit committee as a moderating variable is only able to weaken the relationship between financial pressure and potential financial statement fraud.

Perfil epidemiológico dos acidentes automobilísticos na cidade de Volta Redonda -RJ no ano de 2015
Authors: De Oliveira Glauber Correia , Marcelino Priscila da Silva
Published: October 2021

As causas externas estão entre as três principais causas de morbimortalidade no mundo. E dentro dessa classificação, os acidentes automobilísticos certamente ocupam papel de destaque, causando sério impacto social, econômico, psico/emocional e moral, além de ser fator determinante de morbimortalidade, principalmente na população chamada economicamente ativa e em idade fértil. O objetivo principal desse trabalho foi traçar um perfil epidemiológico dos acidentes automobilísticos ocorridos na Cidade de Volta Redonda-RJ no ano de 2015 para, a partir desses dados, promover estratégias que visem reduzir a quantidade e a gravidade desses acidentes, além de melhorar a qualidade do atendimento, reduzindo assim a morbimortalidade desses pacientes. Para atingir esse objetivo, realizamos um estudo transversal, com utilização de dados do DATASUS (dados estes disponíveis para o público sem qualquer restrição), utilizando como descritores primários “acidentes de transporte”, “cidade de Volta Redonda” e “ano de 2015”; e como descritores secundários as demais informações pertinentes ao tema (como “faixa etária”, “gastos”, “gênero”, ‘óbitos”, “tipos de acidente de transporte”, entre outros). Através da realização deste estudo observamos o grande impacto causado pelos acidentes automobilísticos, com destaque para o elevado número de internações decorrentes de acidentes com motocicletas, e depois pedestres e ocupantes de veículos de passeio, enquanto que as internações em consequência dos outros tipos de acidentes ocorreram em proporções significativamente menores. Quando o foco das avaliações foi o gasto decorrente do atendimento a essas vítimas a perfil foi semelhante. Em relação aos óbitos (15 no total), houve um equilíbrio entre vítimas de acidentes envolvendo motocicletas, pedestres e veículos de passeio, sendo apenas um classificado como “outros tipos de acidente de transporte”. Além disso, observou-se que a maioria das internações e dos óbitos (por qualquer tipo de acidente) ocorreu na população de sexo masculino. Assim, foi possível concluir que o impacto dos acidentes envolvendo veículos de transporte é relevante na cidade de Volta Redonda-RJ, seguindo a tendência mundial contemporânea. Desta forma, é necessário que se trace estratégias para redução da quantidade e da gravidade dos acidentes automobilísticos, bem como de otimização dos atendimentos intra e extra-hospitalar, para que seja possível a redução da morbimortalidade e consequentemente dos seus impactos sociais, econômicos, psico/emocionais e morais.

Published: October 2021

Apesar das medidas de prevenção e controle da poluição atmosférica, as indústrias siderúrgicas são percebidas pela população ao seu redor como uma das maiores fontes de emissão de poluentes, principalmente, em relação à qualidade do ar. Neste sentido, as emissões atmosféricas devem ser consideradas como aspectos relevantes para a gestão ambiental e serem tratadas com restrição. O objetivo do estudo em questão foi realizar uma análise da qualidade do ar da Cidade de Volta Redonda, considerando dados de qualidade do ar disponíveis entre os anos de 2010 a 2014 e sua possível correlação com as atividades da siderurgia, considerada nesta região uma das principais fontes de poluição. Também foi realizada uma comparação da legislação brasileira com a legislação dos Estados Unidos e da Europa, bem como os níveis de qualidade do ar da cidade de Volta Redonda frente a estas legislações.

Aspectos quantitativos do comportamento de defesa da perereca-da-folhagem Phyllomedusa rohdei Mertens, 1926
Authors: Ennes Felipe
Published: October 2021

Estratégias anti-predação desenvolvidas por anfíbios anuros são variadas e podem ser observadas isoladamente ou em combinação com outros comportamentos. O comportamento de tanatose e encolher-se (do inglês "shrinking") são exemplos de exibição corporal, onde os indivíduos se mantêm imóveis, fingindo-se de morto, confundindo e/ou enganando predadores. Phyllomedusa rohdei é uma perereca conhecida por adotar o comportamento defensivo de encolher-se, inclusive no ato de manuseio do indivíduo. O objetivo deste estudo é analisar a influência de diferentes características (horário, grau de atividade, altura do poleiro, distância para o indivíduo cantor mais próximo, tamanho, massa, condição física e condição climática da noite) na adoção ou não deste comportamento no momento de captura do indivíduo, bem como a influência das características analisadas no tempo que cada indivíduo permanece imóvel. Foram analisados um total de 18 machos. Nenhuma fêmea foi capturada e apenas dois machos permaneceram ativos após a captura (ou seja, eles não ficaram parados). Todos os outros adotaram a estratégia de encolher-se quando manuseados. Em média, cada macho permaneceu imóvel por 163,5s. A análise de regressão mostrou que nenhuma das variáveis bióticas e abióticas influenciou significativamente o tempo que os machos permaneceram imóveis. No entanto, quando analisadas separadamente, a altura do poleiro foi negativamente correlacionada com o tempo de imobilidade. Considerando que os machos mais ativos ocupam os poleiros mais elevados da vegetação, porque estes seriam os locais com a menor degradação do sinal acústico ou porque esses poleiros são os melhores pontos de observação da área à procura de fêmeas, esses machos poderiam estar mais estimulados, de modo que permaneçam menos tempo imóveis. Sugerimos que machos nestas condições (em sítios de vocalização mais elevados e, possivelmente, mais favoráveis) voltem mais rapidamente as suas atividades após serem perturbados.
