Published: August 2021

This article provides a general description of the powers and competencies of public authorities exercising public administration in the field of air protection. Atmospheric air is proposed to mean an element of the natural environment, which is an invisible mixture of gases within the territory of Ukraine and contains vital chemicals and compounds necessary for the existence of living organisms. It is determined that the subjects of public administration in the field of air protection are the system of bodies of general and special competence, which exercise public administration powers to restore, preserve, ensure air quality and ensure the right of citizens to air, and take the necessary measures. to reduce the incidence of air pollution due to air pollution. The subjects of public administration in the field of air protection are proposed to be divided into two groups: 1. subjects of general competence (Verkhovna Rada of Ukraine, President of Ukraine, National Security and Defense Council of Ukraine) and 2. subjects of special competence (Cabinet of Ministers of Ukraine) (Government of Ukraine), Ministry of Environmental Protection and Natural Resources of Ukraine, State Ecological Inspectorate of Ukraine, Ministry of Health of Ukraine, local state administrations and local governments). Based on the analysis of legislative and by-laws, which determine their administrative and legal status in general, the powers of these entities in the field of air protection are highlighted. Emphasis is placed on the special tasks of these actors in order to preserve the health of the nation.

Published: August 2021

This study aims to investigate the causality relationships between energy use, energy intensity, energy price and economic growth. Regarding the data analysis, the study covered the period from 1980 until 2020. All relevant preliminary tests were conducted in order to validate the data before the main analysis. We deployed ARDL bound test of cointegration approach for long-run relationship, as well as the granger causality test proposed by Toda and Yamamota (1995). The empirical results showed the presence of long-run relationship among the variables. We also found that energy use and economic growth has a bidirectional relationship. Similarly, we observed a presence of another feedback causal effect between energy intensity and economic growth. Likewise, a bi-directional causal relationship exists between energy price and economic growth in the Nigerian economy. The study makes available policy recommendations in the last part of the paper.

The production of multicomponent vaccines faces certain difficulties, since all antigens included in the composition should be of an optimal amount, not compete with each other (not cause interference) and ensure the formation of a stable and long-term immune response. However, in addition to effectiveness, it should be taken into consideration that antigen overload can have a negative effect on the safety of the drug, and, therefore, it is necessary to carefully study all possible negative reactions in naturally susceptible animals. Our work presents the results of a study of the safety of the inactivated vaccine against streptococcosis in pigs «VERRES-STREPTO» developed in the period of 2016–2020. The study was carried out on laboratory animals, as well as on piglets and sows. When using the drug according to the requirements indicated in the instructions, no local and / or systemic undesirable reactions were detected in experimental animals: anaphylaxis, depression, adynamia, fever, abortion. The formation of minor aseptic oedemas, which resolved on their own within 7–10 days, was noted at the injection site. The studies showed that the drug is safe for laboratory and naturally susceptible animals in the effective recommended and double doses. The expected efficacy of the use of this drug will significantly outweigh the potential risks of its use.

This article presents materials on the production test of the Abiopeptid feed additive on calves of the Holstein breed raised in Sovkhoz Golovkovo LLC MTF Kryukovo, two groups of 20 calves were formed in each experimental group, the Abiopeptid feed additive was soldered at a rate of 1 ml/kg live masses. As a result, the use of the Abiopeptid feed additive at a dose of 1 ml / kg of calf live weight has been established that it does not negatively affect the physiological parameters of the clinical status of animals. The use of the Abiopeptid feed additive increases the average daily gain of calves by 100,0 g compared with the control group. The results of blood tests suggest a reliable stimulating effect of the Abiopeptid feed supplement on metabolic processes, increasing the parameters characterizing hematopoiesis. Thus, the Abiopeptid feed additive can be recommended for use by animals during the period of active growth and development of the body, to stimulate weight gain, and activate animal metabolism, and prevent anemia and malnutrition. In order to determine the effectiveness of the feed additive, we studied the indicators of the clinical status of calves and a biochemical and general blood test.

Authors: Bailey J. C. , Brooks C. K.
Published: August 2021

The whole-rock geochemistry and mineral chemistry of six samples of Lower Cretaceous tholeiitic basalt from Franz Josef Land, U.S.S.R., have been studied. Geochemical criteria indicate that the basalts are initial rifting tholeiites characterised by low contents of Ti and other H-elements, suggesting derivation from a depleted mantle source. These tholeiites formed during a Lower Cretaceous rifting stage in the formation of the Arctic Ocean basin, most likely the opening of the Canada Basin.
Hadimopanella from the Lower Cambrian of North
Greenland: structure and affinities
Authors: Almgreen S. E. Bendix , Peel John S.
Published: August 2021

New records of minute phosphatic sclerites of Hadimopanella are described from the Aftenstjernesø and Henson Gletscher Formations of western and central North Greenland in strata of Early Cambrian age. The new material illustrates the occurrence of mineralisation in the wall between individual sclerites and confirms earlier suggestions of the close relationship between Hadimopanella and Utahphospha. Both forms are compared with spicules produced by living and fossil compound ascidians of the genus Cystodytes and it is concluded that they may have been Early Palaeozoic representatives of the chordate Class Urochordata.

Published: August 2021

Arthrorhachis tarda (Barrande, 1846) and Sphaeragnostus cingulatus (Olin, 1906) are described from the Upper Ordovician (Harjuan Series) of Sweden and Bornholm, Denmark. S. cingulatus is extremely rare, while A. tarda is generally abundant in middle Ashgillian strata and known from a great number of localities in southern and south-central Scandinavia. Outside Scandinavia, A. tarda is frequently encoun- tered in the pre-Himantian Ashgill of Poland, Bohemia, various parts of the British Isles, and Kazakh­stan. In most of these areas, the species is generally confined to mudstone sequences, and it is usually associated with faunas of Mediterranean type. The generic concept of Sphaeragnostus is revised.

Published: August 2021

We present the detections of shocked molecular hydrogen (H2) gas in near- and mid-infrared and broad CO in millimeter from the mixed-morphology supernova remnant (SNR) HB 3 (G132.7+1.3) using the Palomar Wide-field InfraRed Camera, the Spitzer GLIMPSE360 and Wide-field Infrared Survey Explorer (WISE) surveys, and the Heinrich Hertz Submillimeter Telescope. Our near-infrared narrow-band filter H2 2.12 μm images of HB 3 show that both Spitzer Infrared Array Camera and WISE 4.6 μm emission originates from shocked H2 gas. The morphology of H2 exhibits thin filamentary structures and a large scale of interaction sites between the HB 3 and nearby molecular clouds. Half of HB 3, the southern and eastern shell of the SNR, emits H2 in a shape of a butterfly or W, indicating the interaction sites between the SNR and dense molecular clouds. Interestingly, the H2 emitting region in the southeast is also co-spatial to the interacting area between HB 3 and the H ii regions of the W3 complex, where we identified star-forming activity. We further explore the interaction between HB 3 and dense molecular clouds with detections of broad CO(3-2) and CO(2-1) molecular lines from the southern and southeastern shell along the H2 emitting region. The widths of the broad lines are 8–20 km s−1; the detection of such broad lines is unambiguous, dynamic evidence of the interactions between the SNR and clouds. The CO broad lines are from two branches of the bright, southern H2 shell. We apply the Paris–Durham shock model to the CO line profiles, which infer the shock velocities of 20–40 km s−1, relatively low densities of 103–4 cm−3, and strong (>200 μG) magnetic fields.

The DECam Local Volume Exploration survey (DELVE) is a 126-night survey program on the 4 m Blanco Telescope at the Cerro Tololo Inter-American Observatory in Chile. DELVE seeks to understand the characteristics of faint satellite galaxies and other resolved stellar substructures over a range of environments in the Local Volume. DELVE will combine new DECam observations with archival DECam data to cover ∼15,000 deg2 of high Galactic latitude (∣b∣ > 10°) southern sky to a 5σ depth of g, r, i, z ∼ 23.5 mag. In addition, DELVE will cover a region of ∼2200 deg2 around the Magellanic Clouds to a depth of g, r, i ∼ 24.5 mag and an area of ∼135 deg2 around four Magellanic analogs to a depth of g, i ∼ 25.5 mag. Here, we present an overview of the DELVE program and progress to date. We also summarize the first DELVE public data release (DELVE DR1), which provides point-source and automatic aperture photometry for ∼520 million astronomical sources covering ∼5000 deg2 of the southern sky to a 5σ point-source depth of g = 24.3 mag, r = 23.9 mag, i = 23.3 mag, and z = 22.8 mag. DELVE DR1 is publicly available via the NOIRLab Astro Data Lab science platform.
A surrogate-based approach to nonlinear, non-Gaussian joint state-parameter data assimilation
Authors: Maclean John , Spiller Elaine T.
Published: August 2021

Many recent advances in sequential assimilation of data into nonlinear high-dimensional models are modifications to particle filters which employ efficient searches of a high-dimensional state space. In this work, we present a complementary strategy that combines statistical emulators and particle filters. The emulators are used to learn and offer a computationally cheap approximation to the forward dynamic mapping. This emulator-particle filter (Emu-PF) approach requires a modest number of forward-model runs, but yields well-resolved posterior distributions even in non-Gaussian cases. We explore several modifications to the Emu-PF that utilize mechanisms for dimension reduction to efficiently fit the statistical emulator, and present a series of simulation experiments on an atypical Lorenz-96 system to demonstrate their performance. We conclude with a discussion on how the Emu-PF can be paired with modern particle filtering algorithms.
Open-loop equilibrium mean-variance reinsurance, new business and investment strategies with constraints
Authors: Zhang Liming , Wang Rongming , Wei Jiaqin
Published: August 2021

In this paper, we study a general mean-variance reinsurance, new business and investment problem, where the claim processes of original and new businesses are modeled by two different risk processes and the safety loadings of reinsurance and new business are different. The retention level of the insurer is constrained in \begin{document}$ [0,1] $\end{document} and the controls of new business and risky investment are required to be non-negative. This model relaxes the limitations of those in existing research. By using the projection onto the convex set controls valued in, we obtain an open-loop equilibrium reinsurance-new business-investment strategy explicitly. We also show that the obtained equilibrium strategy is the optimal one among all deterministic strategies in the sense that it yields the smallest mean-variance cost. In the case where original and new businesses are the same, the equilibrium strategy is given in closed-form and its sensitivities to safety loadings are shown by numerical examples. At last, by comparing with the case where acquiring new business is prohibited, we show that allowing writing new policies indeed improves the performance of the insurer's risk management.

The strong P-regular splitting is put forward and defined for iterative methods of non-Hermitian linear systems in the paper. The strong P-regular splitting combining SOR iterative methods and relaxed SOR iterative methods are established, and conditions guaranteeing the convergence are presented. Furthermore, two numerical experiments are done to illustrate the convergence and effectiveness of our iterative methods.

Virtual reality (VR) is increasingly used for presurgical planning and teaching during surgery. However, VR aided presurgical planning toolbox for left ventricular assist device (LVAD) implantation is not widely available. We investigated the use of a VR environment with wearable headsets and touch controllers in simulating an implant in an 11-year-old boy. The technology played a significant role in the optimal positioning of the LVAD.

High-dose methotrexate (HDMTX) is gaining importance in the management of acute lymphoblastic leukemia (ALL). Its efficacy and toxicity depends on dose strength, route of administration, and infusion time. HDMTX toxicities can be controlled by continuous monitoring of urine pH and adequate supportive care (hyper-hydration, alkalinizing agents, and leucovorin rescue). A patient suffering from B cell Ph + ALL was kept on Berlin-Frankfurt-Münster-90 protocol and administered methotrexate 8 g/cycle by intravenous infusion with normal saline over 6 h. He developed leucopenia and severe anemia after receiving the first cycle of chemotherapy, which was treated with subcutaneous filgrastim 300 mcg OD for 5 days and 1 pint red blood cell. After the third cycle, patient developed mucositis and treated with leucovorin and local anesthetics; and continued the chemotherapy. In conclusion, the patient was continuously monitored for urine pH and tolerated the HDMTX well when provided adequate supportive care.

Within the humanitarian arena and since the introduction of the humanitarian reform process in 2005, the cluster approach was introduced to strengthen the cooperation and accountability between agencies working in the same field. Such an integrated approach is particularly needed and relevant in emergencies like cholera, especially in countries undergoing internal conflicts like Yemen. Several areas of concern have been identified during the past field experiences, which include dysfunctional cooperation as a result of different mandates as well as the relationship between nongovernmental organizations and their donors. Control of environmental health services is, for instance, the responsibility of several clusters/agencies and stakeholders, which usually results in a complicated and sometimes confusing approaches to address gaps and barriers. As far as the drinking water quality monitoring and surveillance are concerned, sampling and testing and compilation of data are usually carried out by many agencies included in the health and water sanitation and hygiene (WASH) clusters. We believe that the cluster theoretical approach for emergency response remains a turning point for the humanitarian arena. However, lessons from the recent past, especially in the management of a cholera outbreak in fragile settings, may serve as a serious reflection on roles and dynamics within the blurred border between health and WASH. Specifically, cluster leads in the field have the responsibility for ensuring that humanitarian actors working in their sectors remain actively engaged in addressing crosscutting concerns such as the environment.

Podoconiosis is a type of tropical lymphedema that is clinically distinguished from lymphatic filariasis (LF) because it is ascending and commonly bilateral but asymmetric. The disease is a result of a genetically determined inflammatory reaction to long-term exposure to mineral particles in irritant red clay soils derived mainly from volcanic soils. We conducted the first nationwide mapping of the prevalence and risk factors of podoconiosis in Kenya. We performed a population-based cross-sectional survey to determine the national prevalence of podoconiosis and included 6,228 individuals from 48 villages in 24 sub-counties across 15 counties. Participants answered a questionnaire about the history of symptoms compatible with podoconiosis, received a point-of-care antigen test, and underwent a physical examination if they had lymphedema. A confirmed case of podoconiosis was defined as a case in a resident of the study village who had lower limb bilateral and asymmetric lymphedema lasting more than 1 year, negative test results for Wuchereria bancrofti antigen, and other causes of lymphedema ruled out. Of all the individuals surveyed, 89 had lymphedema; of those, 16 of 6228 (0.3%; 95% confidence interval [CI], 0.1–0.5) were confirmed to have podoconiosis. A high prevalence of podoconiosis was found in western (Siaya, 3.1%; Busia, 0.9%) and central (Meru, 1.1%) regions, and a low prevalence was observed in northern (Marsabit, 0.2%), eastern (Makueni, 0.2%), and coastal (Tana River, 0.1%) regions. The identified risk factors were age 56 years or older (adjusted odds ratio [aOR], 5.66; 95% CI, 2.32–13.83; P < 0.001) and rarely wearing shoes (aOR, 18.92; 95% CI, 4.55–78.71; P < 0.001). These results indicated that the podoconiosis prevalence is low and localized in Kenya; therefore, elimination is achievable if appropriate disease prevention, management, and behavioral strategies are promoted.
Interpretação do Ensino de Frações em Livros do GRUEMA
Authors: Gouveia Relicler Pardim
Published: August 2021

O objetivo deste artigo é apresentar uma interpretação do ensino de frações, a partir da análise do “Curso Moderno de Matemática para o ensino de 1.º grau”, de Manhúcia Perelberg Liberman, Lucília Bechara Sanchez e Anna Franchi. Pretende-se compreender que matemática para ensinar pode ser interpretada ao analisar as orientações contidas nesta obra. O texto que aqui apresentamos apoia-se nos conceitos elaborados pela Equipe de Pesquisa em História Social da Educação, da universidade de Genebra – saberes a ensinar e saberes para ensinar –, bem como as apropriações desses conceitos assumidos pela equipe do GHEMAT-SP, que colocam o saber profissional como tema para análise do ensino e da formação em contexto histórico. Para análise documental, se admitiu como fontes de pesquisa os livros do ensino primário da coleção GRUEMA, dos anos de 1974 e 1975. Os resultados da análise realizada, apontam que uma matemática para ensinar foi objetivada no período do Movimento Matemática Moderna, a partir da construção e do desenvolvimento da obra, e das diversas representações utilizadas para ensinar frações, colocando em foco a expertise das autoras.
Tecnologias Digitais e Práticas de Subitização: Perspectivas na Educação Básica
Authors: Marques Wagner da Silveira
Published: August 2021

O termo subitizing, traduzido para o nosso idioma como subitização, ainda não cunhado fortemente na Educação Matemática, constitui a habilidade em reconhecer um conjunto com poucos objetos, o que, em nossa concepção, tende a se aproximar da capacidade de estimativa do estudante. Sentimo-nos, então, inclinados a investigar indícios da utilização de tecnologias digitais, mediante práticas de numeramento, especialmente no campo da subitização ou estimativa, verificar quais tipos de recursos são utilizados, além da forma como se caracterizam as atividades no âmbito da Educação Básica, por meio da realização de uma revisão sistemática de literatura. De fato, das oito averiguações selecionadas, praticamente nenhuma se refere diretamente à subitização, mas nossas lentes permitiram sinalizar a possibilidade de recursos digitais, bem como de atividades, ambos por nós elencados, capazes de potencializar o aprendizado matemático de estudantes não somente nesse campo, mas abrangendo, inclusive, a estimativa.
Questões Sociocientíficas como Contexto em Livros Didáticos de Matemática para o Ensino Fundamental
Authors: Bernardo José Roberto da Rocha , Dassie Bruno Alves
Published: August 2021

Neste trabalho apresentamos uma pesquisa que focalizou o uso de questões sociocientíficas (QSC) como contextos em livros didáticos de matemática para o Ensino Fundamental no Brasil. Mais especificamente, foram analisados os capítulos de Estatística das obras aprovadas pelo Programa Nacional do Livro Didático – PNLD 2020, com o objetivo de identificar a ocorrência de atividades que valorizem temas como catalisadores de processos reflexivos acerca do contexto para compreender como se dão essas relações. Essas duas perspectivas guiaram nossa pesquisa. Os dados obtidos foram submetidos à análise de conteúdo que favoreceu a construção de categorias temáticas e a realização de inferências e interpretações. Em relação à presença de temas nas obras, observa-se uma grande diversidade, o que é positivo. Em relação à maneira como o potencial de contextualização das QSC se relaciona com o conteúdo tratado, esta ainda se mostra tímida.
Interpretações de Características da Modelagem Matemática Presentes na Literatura a partir das Dimensões da Relação com o Saber

Published: August 2021

Neste artigo apresentamos os resultados de uma pesquisa de caráter qualitativo que teve como objetivo identificar e interpretar características da Modelagem Matemática (MM) presentes na literatura, a partir da noção de relação com o saber e suas dimensões. Para atingir tal objetivo foram levantados artigos sobre MM nos seguintes periódicos: Boletim de Educação Matemática (Bolema); Educação Matemática em Revista (EMR); Revista de Educação Matemática (REMat); Zetetiké. O corpus da pesquisa foi constituído por 30 artigos que abordam a MM por um viés teórico. As análises pautaram-se nos procedimentos sugeridos pela Análise Textual Discursiva (ATD) e desse processo analítico emergiram 14 diferentes unidades de análises (UA) significadas pelos excertos extraídos dos artigos. Tais UA foram organizadas em três categorias que caracterizam a relação com o saber: a dimensão epistêmica, a dimensão pessoal e a dimensão social. Deste processo concluímos que as ações dos professores e dos alunos no âmbito da MM revelam aspectos epistêmicos, pessoais e sociais sobre a aprendizagem da Matemática. Acreditamos que as dimensões da relação com o saber podem servir como foco para propostas de atividades de MM, pois tratam das características das relações de ensino e de aprendizagem entre os sujeitos nelas envolvidos, a saber: a relação entre professor e alunos; a relação entre professor e o saber; e a relação entre alunos e o saber.
