Loops in the fundamental group of which are not represented by circle actions
Authors: Anjos Sílvia , Barata Miguel , Pinsonnault Martin , Reis Ana Alexandra
Published: June 2022

We study generators of the fundamental group of the group of symplectomorphisms
$\operatorname {\mathrm{Symp}} (\mathbb C\mathbb P^2\#\,5\overline { \mathbb C\mathbb P}\,\!^2, \omega )$
for some particular symplectic forms. It was observed by Kȩdra (2009, Archivum Mathematicum 45) that there are many symplectic 4-manifolds
$(M, \omega )$
, where M is neither rational nor ruled, that admit no circle action and
$\pi _1 (\operatorname {\mathrm {Ham}} (M,\omega ))$
is nontrivial. On the other hand, it follows from Abreu and McDuff (2000, Journal of the American Mathematical Society 13, 971–1009), Anjos and Eden (2019, Michigan Mathematical Journal 68, 71–126), Anjos and Pinsonnault (2013, Mathematische Zeitschrift 275, 245–292), and Pinsonnault (2008, Compositio Mathematica 144, 787–810) that the fundamental group of the group
$ \operatorname {\mathrm{Symp}}_h(\mathbb C\mathbb P^2\#\,k\overline { \mathbb C\mathbb P}\,\!^2,\omega )$
, of symplectomorphisms that act trivially on homology, with
$k \leq 4$
, is generated by circle actions on the manifold. We show that, for some particular symplectic forms
$\omega $
, the set of all Hamiltonian circle actions generates a proper subgroup in
$\pi _1(\operatorname {\mathrm{Symp}}_{h}(\mathbb C\mathbb P^2\#\,5\overline { \mathbb C\mathbb P}\,\!^2,\omega )).$
Our work depends on Delzant classification of toric symplectic manifolds, Karshon’s classification of Hamiltonian
$S^1$
-spaces, and the computation of Seidel elements of some circle actions.

X

, and denote by

\ell_{\infty}(C)

the

\ell_{\infty}

-sum of

C

. In the present paper, by using the degree of nondensifiability (DND), we introduce the class of

r

-

\Delta

-DND-contraction maps

f: \ell_{\infty}(C)\rightarrow X

and prove that if

f(\ell_{\infty}(C))\subset C

then there is some

Existências Líquidas
Authors: Da Costa Tavares Khetllen
Published: June 2022

A partir de retratos de mulheres indígenas datados da primeira metade do século XX, conservados no acervo do Museu da Imagem e do Som de Manaus (MISAM), este estudo, por meio da poética do livro de artista Existências Líquidas, apresenta um olhar subjetivo acerca das representações de povos originários. A obra partiu do desejo de entrelaçar afetos às imagens das retratadas memorando hábitos do cotidiano da minha família afro-indígena, como as receitas de chás, que aprendi com minha avó materna Norma Teixeira. As fotos das retratadas, agrego fragmentos de vegetais que coletei durante caminhadas em Manaus e os associei à resistência do matagal no âmbito urbano como um ato de resistir da população indígena frente as políticas racistas, que desconsideram os modos de vida desses povos.

Published: June 2022

Atopic Dermatitis (AD) is a chronic disease that generates scaly lesions on the skin, generates itching, erythema and affects 20% of children and about 5% of adults. Currently AD is considered a systemic disorder associated with the development of other comorbidities, whose pathophysiology is not completely understood, but there is a strong correlation with the dysfunction of the skin physical barrier and immunobiological dysregulation. The present study aims to analyze the effectiveness of the use of probiotics administered orally for the adjuvant treatment of patients with AD, evaluating their effectiveness, which are the most used, the correlation with the intestinal microbiota and the immune system, if there is greater effectiveness according to the age group and which strains and dosages are most indicated. The study used a prospective literature review, academic material in Portuguese and English, in the PubMed, Scielo and LILACS databases from 2017-2022 for works on the topic of probiotic use in AD. The literature review showed that although the first-choice treatment for AD is corticosteroids, probiotics as an adjuvant can reduce the need for corticosteroids. The most used strains are Lactobacillus plantarum and Lactobacillus fermentum, but the doses vary greatly between authors and commercial presentations, ranging from 5-10x109CFU for the first microorganism and 1-2x109CFU for the second. The higher incidence of efficacy of its in children and controversial conclusions on dosage was due to several factors, such as environmental, diet, which is indicative of the need for future studies to establish dose and identify proven clinical efficacy.
Icons from the collection of Tatyana Mavrina (1900–1996) in the Department of Private Collections of the Pushkin State Museum of Fine Arts
Authors: Важкая М.А.
Published: June 2022

В 1994–1997 гг. в отдел личных коллекций Государственного музея изобразительных искусств им. А.С. Пушкина поступило 25 икон из собрания художника Татьяны Алексеевны Мавриной (1900–1996). Особенностью данной коллекции является творческий подход при ее формировании. Наибольшая часть икон носит народный характер, прекрасно сочетаясь с сохраняющими древнерусские традиции русскими прялками XIX века или акварельными работами, выполненными Т.А. Мавриной. В исследовании представлено несколько икон из собрания художника Татьяны Алексеевны Мавриной, позволяющих увидеть стремление коллекционера собрать яркие образцы древнерусской иконописи XV–XVII веков. Некоторые иконы ранее упоминались в искусствоведческих исследованиях (поясные изображения архангелов Михаила и Гавриила из деисусного чина, икона «Битва новгородцев с суздальцами»), тогда как икона «Богоматерь на престоле и Никола Можайский с избранными святыми на полях» подробно описана впервые. Данная статья затрагивает лишь часть исследования иконописи из собрания Татьяны Алексеевны Мавриной, необходимой для введения в научный оборот образцов русской иконописи XV–XVII веков.

25 icons from the collection of the artist Tatyana Alekseevna Mavrina (1900–1996) entered the Department of Private Collections of the Pushkin State Museum of Fine Arts in 1994–1997. The collection is distinguished by a creative approach in its formation. Most of the icons are of a folk character, perfectly combined with the Russian spinning wheels of the 19th century, which preserve ancient Russian traditions, or watercolor works by T.A. Mavrina. The study presents several icons from the collection of the artist Tatyana Alekseevna Mavrina. They allow you to see the collector's desire to collect bright examples of ancient Russian icon painting of the 15th–17th centuries. Some of the icons were before mentioned in art research (belt images of the archangels Michael and Gabriel from the Deesis Rank, the icon “The Battle between Novgorod and Suzdal”), while the icon “Mother of God enthroned and Nikola Mozhaisky with some saints on the fields” is described in detail for the first time. This article covers only part of the study of iconography from the of Tatyana Mavrina collection necessary for the introduction to the scientific circle of the samples of Russian icon painting of the 15th–17th centuries.

Published: June 2022

В 2022 году исполнилось 110 лет со дня кончины известного заонежского художника-иконописца из с. Космозеро Михея Ивановича Абрамова. Иконописная мастерская Абрамовых, славившаяся по всему Заонежью, действовала на протяжении целого столетия. Иконы, писанные Абрамовыми, можно было встретить как в домашних крестьянских иконостасах, так и во многих храмах Олонецкой губернии. В настоящее время большая часть абрамовских икон утрачена либо хранится в собраниях музеев республики без атрибуции. Наиболее полное собрание иконописных работ космозерских иконописцев хранится в фондах музея-заповедника «Кижи». В статье рассматривается история формирования музейной коллекции, характеризуются иконы, написанные в этой мастерской, в том числе и уникальные подписные иконы заонежских изографов; приводятся воспоминания односельчан и членов семьи об организации работы и жизненном пути последнего иконописца Заонежья Ивана Михеевича Абрамова; поднимается вопрос о судьбе коллекции икон и оборудования мастерской Абрамовых, вывезенных в Финляндию в период финской оккупации советской Карелии в 1943 г.; рассматриваются возможности пополнения коллекции в настоящее время. Исследование опирается на документы Национального архива Республики Карелия, Национального архива Финляндии (Хельсинки), материалы Научного архива музея-заповедника «Кижи», в том числе экспедиционные записи.

The article is dedicated to the 110th anniversary of the death of the famous icon painter from Zaonezhye, Mikhey Abramov. The Abramovs' icon-painting workshop, famous throughout Zaonezhye, operated for a century. The icons painted by the Abramovs were both in home peasant iconostases and in many churches of the Olonets province. At present, most of the Abramov icons have been lost or are kept in the collections of museums in the Republic of Karelia without attribution. The funds of the Kizhi Museum-Reserve store the most complete collection of icon-painting works of Kosmozero icon painters. The article discusses the history of the formation of the museum collection, characterizes the icons painted in this workshop, including the unique signature icons of Zaonezhsky iconographers. The author cites the memories of fellow villagers and family members about the organization of work and the life path of the last icon painter of Zaonezhie, Ivan Abramov. The article also raises the question of the fate of the collection of icons and equipment of the Abramov workshop, taken to Finland during the Finnish occupation of Soviet Karelia in 1943, and considers the possibility of replenishing the collection at the present time. The study is based on documents from the National Archives of the Republic of Karelia, the National Archives of Finland (Helsinki), materials from the Scientific Archives of the Kizhi Museum-Reserve, including expeditionary records.

Authors: Нечаева Г.Г.
Published: June 2022

В статье приводятся описание и анализ образа «Богоматери Огневидной». Памятники этой редкой иконографии хранятся в Ветковском музее старообрядчества и белорусских традиций (Республика Беларусь). Представлены основные этапы формирования и разнообразие вариантов образа, его участие в сложных композициях целостных комплексов памятников иконописи, происходящих из локальных старообрядческих традиций региона Ветки и Стародубья; его роль в старообрядческой культуре Ветки. На примере местных памятников анализируются живописные особенности воплощения образа. В символическом и семантическом ключе представляется иконография многочастной иконы с включением образа Богоматери Огневидной; в частности, показано, что духовный смысл образа был близок монастырскому кругу и скитническому движению Ветки и Стародубья, мистическим традициям исихазма, а тема огневидных образов и глубины символики огня представляет стройную иконографическую программу ветковской школы иконописи.

The article describes and analyzes the image of the “Our Lady of Fire”. Examples of this rare iconography are kept in the Vetka Museum of the Old Believers and Belarusian Traditions (Republic of Belarus). The main stages of formation and variety of variants of the image, its participation in complex compositions of integral complexes of icon-painting monuments, originating from the local Old Believer traditions of the Vetka and Starodubye region are presented, as well as its role in the Old Believer culture of Vetka. On the example of local monuments, the picturesque features of the embodiment of the image are analyzed. The author analyzes the iconography of the multi-part icon with the inclusion of the image of the Mother of God of Fire in symbolic and semantic aspects. In particular, it is shown that the spiritual meaning of the image was close to the monastic circle and the hermitage movement of Vetka and Starodubye, the mystical traditions of hesychasm, and the theme of fire-like images and the depth of the symbolism of fire represents a harmonious iconographic program of the Vetka school of icon painting.

O objetivo deste artigo é analisar as respostas elaboradas pelos mapuche diante dos movimentos expansionistas que pretendiam incorporar o Wallmapu à órbita do poder estatal chileno, ressaltando o papel dos indígenas como sujeitos capazes de se adaptar e resistir às políticas criollas.
“Questão de índios” e “questão de fronteiras”: conexões transnacionais entre os Estados Unidos e a Argentina pelas cartas de Miguel Malarin
Authors: Pompeu Ana Carollina Gutierrez
Published: June 2022

Entre os anos de 1877 e 1879, o militar argentino Miguel Malarin esteve nos Estados Unidos para observar e estudar temas como organização militar, conflitos contra sociedades indígenas e expansão das fronteiras internas. Essa viagem, feita a mando de Julio Argentino Roca, importante militar do cenário argentino, rendeu um conjunto de cartas escritas por Malarin a Roca, que consistem na principal fonte primária deste artigo. As cartas demostram que os personagens do período refletiram sobre situações como a expansão das fronteiras étnicas de maneira transnacional. Tal percepção motivou a viagem de Miguel Malarin aos Estados Unidos, país que parecia vivenciar situação análoga à encontrada na Argentina, a respeito das tentativas do Estado em promover a submissão dos povos originários e a incorporação de seus territórios. A “questão de índios” e a “questão de fronteira” são os pontos principais do original argumento de Malarin, que foram encaminhadas a Roca no conjunto epistolar analisado.
José Martí, a Guerra Civil norte-americana e o pensamento político dos abolicionistas nos Estados Unidos (décadas de 1880 e 1890)
Authors: Santos Lucas Machado Machado dos
Published: June 2022

Desenvolvemos neste ensaio uma abordagem transnacional acerca da interpretação histórica do cubano José Martí sobre dois aspectos da História dos Estados Unidos que estão intimamente conectadas com a História Mexicana e das Nações do Caribe, principalmente Cuba: as consequências da Guerra Civil Americana e a luta abolicionista nos Estados Unidos. Acreditamos que esta chave é fundamental para compreendermos os volumosos textos jornalísticos que este importante intelectual e líder político cubano escreveu sobre o gigante do Norte e sobre estes dois temas selecionados, em particular. Realizamos neste ensaio, uma reflexão que dialoga com a historiografia latino-americana e estadunidense e pesquisas mais recentes sobre a obra deste intelectual, com foco no debate racial, para, por fim, apontar, a partir da análise de artigos para a imprensa, as perspectivas do abolicionismo radical e do anticolonialismo diretamente no posicionamento de José Martí durante as décadas de 1880 e 1890 do século XIX.

Published: June 2022

This study aims to determine suitable biochar precursor for local production of biochar as an alternative low-cost solution to address the persistent water supply issue in rural areas in Sarawak. A series of physicochemical characterization and adsorption studies were conducted for biochar pyrolysed from bamboo, dried leaves, wood shavings, rice husk, tree branch and wood chip, in a stainless-steel canister (without oxygen) at 600oC for three hours using a muffle furnace. Bamboo was the only precursor which fulfilled the requirements for water treatment in rural areas, i.e., biochar yield, structural integrity in water and adsorption characteristics. The pyrolysis of bamboo achieved a biochar yield of 32.8%, which attributed to the high fixed carbon content of 70.9% required for adsorption. The biochar consisted of homogeneous carbon structures with BET surface area of 317 m2/g, total pore volume of 0.189 cm3/g and micropores averaging 1.218 nm, which demonstrated favourable adsorption characteristics. The selection of bamboo as precursor is practical in rural areas as it is easily obtained and safe to be pyrolyzed into biochar. The application of biochar for water treatment helps to overcome the water supply issues and promote sustainable biomass waste management in rural areas.

Due to the unsatisfactory performance of MS544-5 in estimating the design capacity of bolted timber connections, this present study was initiated to validate the existing predictive equations used by the Malaysian Standard (MS544-5). An evaluation of the European Yield Model (EYM) equation was also done to provide an optimal design equation for the bolted connection design in local hardwood. To verify these two sets of equations, a series of bolted timber connection tests was conducted on Nyatoh hardwood. Nyatoh was chosen as its strength makes it ideal for use as structural timbers, either as roof rafters or floor joists in masonry building constructions. The bolted timber connection tests conducted involved eight types of bolt configurations and the tests on each configuration was done in sets of 10 specimens. The experimental values obtained were then compared with the predictive equations of MS544-5 and EYM to examine their effectiveness. From the comparison, it was found that the prediction values given by MS544-5 were overly conservative with an average effective ratio of 0.34 while the EYM had an average effective ratio of 1.09. Thus, the use of EYM equations was recommended for the sustainable retrofit design development of Malaysian masonry buildings.

The performance of Fibre Reinforced Mortar (FRM) mixed with microfine size Palm Oil Fuel Ash was investigated in this study (POFA). The ideal volume of POFA and fibre in the mixed mortar is calculated in order to generate a cost-effective high-strength mortar with increased ductility. In this experimental investigation the polypropylene fibre used ranged from 0 kg/m3 to 20 kg/m3 and the replacement of cement with microfine POFA content of 0% and 40% (optimum) was studied. The mechanical properties of fibre reinforced masonry in the presence of the POFA was tested using compressive strength, flexural and split tensile tests. The surface morphology of the fibre reinforced mortar was studied using scanning electron microscopy (SEM) which showed the good fibre-mortar bond in the morphology of the samples at 7 and 28 days. From the compressive strength results, FRM tester contains 40% microfine POFA as a replacement against cement mixed with 10 kg/m3 of polypropylene fibre is optimum and achieved compressive strength up to 79.5 MPa at the 56th day of curing. Ductility ratio up to 13.3 was achieved from the flexural test for FRM sample with 15 kg/m3 polypropylene fibres. The high strength FRM with inclusion of POFA as supplementary cementitious material had the potential to become a new sustainable material in construction.

The quantification and characterisation of municipal solid waste are indispensables for waste management forethought. This study quantified the municipal solid wastes from three principal council areas in Kuching, the capital city of Sarawak, Malaysia which are the Kuching South City Council, Kuching North City Hall and Padawan Municipal Council to evaluate and analyse the contemporary waste trend and differentiate between the waste streams. The municipal solid waste samples are amassed directly from the source location and categorised according to the socio-economic level of the sampling location sites. This study discovered that there is no significant difference in the waste composition trend generated by the residents in different residential areas. The composition of the solid wastes was found to vary in different socio-economic categories. Organic waste is found to be the highest waste component in all socio-economic groups. The top three municipal waste compositions from the residential areas are organic wastes (61.58% w/w), plastics (12.06% w/w) and nappies/sanitary napkins (11.67% w/w), which ranged from 44.57% to 72.08%. This study provides a recent waste trend database with a detailed analysis of the differences between the waste streams for sustainable waste management in Kuching.

Composite materials have been continuously innovated and developed so that they can be improved in almost any criteria as their characteristics are preferable to single- phase materials. Natural fiber reinforced polymer composites can sustainably reduce inorganic and organic wastes, aside from serving as materials with improved mechanical properties. In this study, fiber extracted from Durio zibethinus (durian) skin was examined. Durio zibethinus (DZ) fiber was fabricated into fiber paper sheets and underwent hot- press lamination to produce a composite. This study investigates the differences between fibers extracted from DZ skin and husk. Tensile and micro Vickers tests were performed on the fabricated composites. The results show that the tensile behaviour of the composite fabricated from DZ skin fiber had a value of 20.1 MPa compared with the composite fabricated from a mixture of skin and husk which had a value of 19.4 MPa. These findings suggest that using durian skin resulted in better tensile strength with a FVF (fiber volume fraction) of 18%, compared with using a mixture of skin and husk which had a FVF range of between 8% and 23%. The hardness, meanwhile, increased with the FVF for the composite fabricated from a mixture of DZ skin and husk. This natural fiber composite has the potential to be used in households, automotive parts, lightweight furniture and many other composite engineering applications.

This paper presents a study on the stabilisation performance of Sarawak soils using GeoCrete® Technology. GeoCrete is used for stabilisation treatments where the soils are treated with ordinary Portland cement (OPC) as a binder and GeoCrete® powder (GCP) as an alkaline additive to improve their strength and elasticity. The use of GCP in soil stabilisation was proven to improve the compressive strength of soils by more than twice the initial strength after 28 days of being treated, with the treatments carried out on three identified soils: Clay, silt and sand. This technique has been successfully implemented on farm roads, rural roads and highways. Thus, further investigation of stabilisation with GCP was conducted on peat, which is known as a material with high permeability and low bearing capacity behaviour. The peat samples collected are mixed at a designated percentage of OPC and 2% of GCP. The compacted and treated peat samples with OPC and GCP were prepared at the optimum moisture content, mixed thoroughly to a uniform condition using a laboratory mixer and air cured for 7 and 28 days in a single batch. The results showed that peat stabilised with GCP has an average of more than 40% of the unconfined compressive strength, qu value after 28 days of curing when compared with peat at the natural state.

This paper describes the field test of a stormwater detention system which is a system designed to hold a specific volume of water and release it slowly over time, in this test case precast concrete modular units are assembled in a residential car porch and connected to a partial roof catchment via a downpipe. Stormwater is held and stored temporarily within the chambers created by the precast concrete pieces. Rainfall and flow data associated with the detention system in terms of the inflow, outflow and water levels data are collected and verification process are performed by comparing the collected data to design data for the intended system.

Makna Teologis Kekudusan Allah Pada Peristiwa Kematian Uza Menurut 2 Samuel 6:6-7
Authors: Weya Mandin , Adhi Benaya Setia
Published: June 2022

Doktrin tentang kekudusan Allah dalam Perjanjian Lama merupakan ajaran teologis yang sulit dimengerti oleh orang Kristen masa kini. Konsep kekudusan Allah dijalankan dengan sangat kaku sehingga mengabaikan unsur kemanusiaan. Bahkan, tidak sedikit para sarjana Alkitab menilai bahwa konsep kekudusan Allah dalam Perjanjian Lama bertentangan dengan kasih Allah. Salah satu narasi yang mencatatkan peristiwa itu adalah kematian Uza. Kematian Uza dalam kitab 2 Samuel 6:6-7 merupakan kematian yang kontroversial. Tidak banyak sarjana yang menyoroti peristiwa itu sesuai dengan teologi Perjanjian Lama secara keseluruhan. Bahkan, beberapa penafsir mengabaikan kesatuan narasi kitab sejarah Perjanjian Lama sehingga hanya terbentuk tafsiran yang bersifat etis. Pencatatan narasi tentang kematian Uza dicatatkan dengan motif khusus dari naratornya. Penelitian ini menggunakan studi kepustakaan, yaitu dengan melakukan studi terhadap literatur yang relevan dengan topik penelitian. Selain itu, penelitian ini juga mempertimbangkan struktur besar dan motif teologis yang dipakai oleh narrator. Penulis kitab Samuel memperhatikan aspek penting dalam kitab Imamat tentang kekudusan Allah. Peristiwa kematian Uza tidak dapat dikaji dengan pendekatan etis, melainkan harus melihat hubungan intertekstual dengan kitab Imamat. Akhirnya, pembaca dapat memahami bahwa teologi kekudusan Allah lebih ditonjolkan dari pada etika dalam peristiwa kematian Uza.The doctrine of the holiness of God in the Old Testament is a theological teaching that is difficult for Christians today to understand. The concept of God's holiness is carried out so rigidly that it ignores the human element. In fact, not a few Bible scholars consider that the concept of God's holiness in the Old Testament is contrary to God's love. One of the narratives that record this event is the death of Uza. Uzzah's death in 2 Samuel 6:6-7 is a controversial death. Not many scholars highlight the event according to Old Testament theology as a whole. In fact, some interpreters ignore the unity of the narrative of the Old Testament historical books so that only ethical interpretations are formed. Narrative recording of Uza's death is recorded with the special motives of the narrator. This study uses a literature study, namely by conducting a study of the literature relevant to the research topic. In addition, this study also considers the large structure and theological motifs used by the narrator. The writer of the book of Samuel noticed an important aspect in Leviticus concerning the holiness of God. The incident of Uza's death cannot be studied with an ethical approach, but must look at the intertextual relationship with the book of Leviticus. Finally, the reader can understand that the theology of God's holiness is emphasized more than ethics in the event of Uzzah's death.
Bom Ladrão, Jesus e Josué:
Authors: Solda Dimas
Published: June 2022

O modo como o chamado “Bom Ladrão”, o malfeitor crucificado ao lado de Jesus (Lc 23,42), se dirige a ele passa despercebido pela maioria dos comentadores desse texto: depois de repreender aquele que profere ofensas, o Bom Ladrão se dirige ao crucificado ao seu lado, chamando-o simplesmente pelo nome: “Jesus”. O presente artigo destaca a importância desse vocativo, único em todo o Novo Testamento, e sugere a relação com teologia do “êisodo”, ligada ao Livro e ao personagem Josué. As ligações textuais são múltiplas, desde a mesma raiz no nome de ambos os personagens, Josué e Jesus, até o aspecto da continuidade e completude da função de Jesus em relação a Josué, marcado pela posição geográfica a oriente do rio Jordão. O verbo “ir, entrar”, revela a função de liderança de Jesus, aos moldes de Josué: com a sua morte, Jesus lidera o novo povo de Deus para a verdadeira terra prometida. O Bom Ladrão, então, é aquele que, por primeiro reconhece e aponta essa realidade.
