Authors: Fauzan Khairil , Salianto Salianto
Published: December 2021

Kesehatan dan Keselamatan Kerja (K3) merupakan hal penting yang harus diterapkan di semua tempat kerja, baik pada sektor formal maupun sektor informal. Salah satu yang dapat dilakukan untuk meningkatkan K3 adalah dengan menggunakan Alat Pelindung Diri. Sayangnya, sering kita temui banyak petugas yang jarang menggunakan APD. Hipotesis yang diajukan adalah penggunaan APD akan meningkat jika petugas memiliki pengetahuan dan sikap positif terhadap penggunaan APD. Metode yang digunakan adalah kuantitatif korelasional dengan pendekatan Cross Sectional. Data yang telah dikumpulkan dianalisis dalam bentuk distribusi frekuensi. Populasi subjek adalah seluruh petugas cleaning service yang ada di RSUD dr. Zubir Mahmud Kabupaten Aceh Timur sebanyak 47 responden. Hasil dari pengabdian ini menunjukkan ada pengaruh dari sikap dan pengetahuan petugas cleaning service terhadap perilaku Kesehatan dan Keselamatan Kerja (K3) tentang penggunaan Alat Pelindung Diri (APD) (p<0,05). Saran bagi Rumah Sakit untuk memperbaharui wawasan semua petugas cleaning service Rumah Sakit dengan mengadakan sosialisasi serta kedepannya diharapkan dapat merekrut tenaga kerja non-medis khususnya cleaning service dengan standar tertentu misalnya membatasi usia produktif dengan standar pendidikan minimal SMA. Dengan demikian tenaga kerja cleaning service akan lebih mudah mencerna materi sosialisasi yang disampaikan dan bisa menjalankan perilaku K3 tentang penggunaan Alat Pelindung Diri (APD) dengan baik dan benar di setiap pekerjaannya.
Patterns of semantics forming for the -out component  in verb-adverbial compounds
Authors:   Oksana V. Koryazhkina Saint-Petersburg State Institute of Technology (Technical University),  Koryazhkina Oksana V.
Published: December 2021

Despite the fact that the issues of word-formation semantics were widely covered, not enough attention was paid to possible differences in the nature of the derived word at the level of the system language and speech. In this article, the issues of derivation are considered from the cognitive point of view on the example of the mechanism of formation of the actual meanings of the component -out in verb-adverbial compounds The aim of the study is to present the lexical meaning of the satellite -out not as a list of lexico-semantic variants, as is customary in the traditional semantic approach, but as a cluster of the most general semantic features necessary for understanding the speech context. The analysis shows that behind the entire semantic structure of the adverbial component -out is the invariant «beyond the limits of a container», as a set of the most stable semantic features that are fixed in the language consciousness of a native speaker and in one of their configurations participate in the process of decoding a specific contextual meaning in accordance with the intuition of the average native speaker. This cluster of features is the system meaning of the word. It corresponds to the verbalized concept, not given directly, but only inferred from the processes of speech on the basis of the word form and in terms of the conditions of consituations.
Cognitive operations of plant meat construal  in Engish media discourse
Authors:   Tatiana I. Semenova Irkutsk State University, Semenova Tatiana I.
Published: December 2021

This paper examines discursive representation of the concept PLANT MEAT in English mass media. The study discusses cognitive operations of categorization, conceptual integration, focus shift involved in conceptualization of a trendy meatless food product. The focus is made on nominal compounds like meatless meat and fake meat in terms of conceptual integration. The study of the relations between formally integrated linguistic structures and conceptually integrated structures supports the claim that the meanings of the compounds are not predictable from their parts. The conclusion is made that the compounds prompt for a specific complex mapping scheme and conceptual blending. Conceptual blends meatless meat and fake meat are viewed as alternative construals of the concept PLANT MEAT and as a result of focus shift mechanism in the semantic structure of the blends. Conceptual blend meatless meat highlights the property ‘absence of meat’ while conceptual blend fake meat focuses on the property ‘imitation’. The concept PLANT MEAT is a way of understanding food made from plants with the appearance similar to meat. The paper reveals pragmatic potential of the conceptual blend PLANT MEAT in shaping health and environmental benefits of a meat-free food style in media discourse.

CONSERVAÇÃO DO SOLO NA HORTICULTURA DAS REGIÕES DE NOVA FRIBURGO (BRASIL) E BUENOS AIRES (ARGENTINA)
Authors: Salles Ricardo Edson , Linhares de Assis Renato , De Aquino Adriana Maria
Published: December 2021

A horticultura é atividade dinâmica e intensa, em que o manejo da matéria orgânica do solo é fundamental. Apresenta-se análise desse manejo com a inserção de plantas de cobertura de solo nas rotações de cultivo de hortaliças em Nova Friburgo (Brasil) e Buenos Aires (Argentina). Isso a partir de estudo de caso com entrevistas de agricultores selecionados com amostragem não probabilística realizada a partir da indicação por atores-chave nos dois países, dos que tivessem experiência consolidada com a temática analisada. Verificou-se nos dois locais que aveia preta era a planta mais utilizada e que isso se devia a ação de técnicos de instituições públicas, porém, não havia planejamento rotineiro das rotações de cultivo para que houvesse o pré-cultivo de plantas de cobertura de solo ao menos uma vez ao ano em todas as áreas de produção. Nas duas regiões estudadas havia pouca oferta de sementes no comércio de insumos, em quantidade e diversidade que favorecesse a prática em questão rotineiramente, inclusive com o uso de maior número de espécies vegetais. As dinâmicas produtivas analisadas têm dilemas correlatos que demandam ações governamentais e políticas públicas específicas, que apoiem o desenvolvimento e disseminação de soluções que visem melhorar sua sustentabilidade.

Published: December 2021

A agricultura familiar tem grande importância no crescimento do país e para a segurança alimentar, porém, com as mudanças sofridas pelo meio rural nas últimas décadas, ela vem sofrendo transformações em vários aspectos. O objetivo do estudo é identificar as características de unidades familiares localizadas na região da Costa Oeste do Paraná, em relação aos membros residentes e suas relações com o novo rural brasileiro. Esta pesquisa caracteriza-se como um estudo descritivo, com abordagem quantitativa e fontes secundárias extraídas do banco de dados dos relatórios do “Projeto de Agricultura Orgânica na BP3”, trabalho conduzido e desenvolvido pela Biolabore - Cooperativa de Trabalho e Assistência Técnica do Paraná, em conjunto com a Itaipu Binacional. As informações foram extraídas dos relatórios de 200 unidades de agricultura familiar.  Identificou-se a ocorrência de pequenas famílias, em média com 3 membros residentes e parcela considerável de unidades onde somente residem o casal. Com relação a faixa etária, verificou-se que os membros residentes estão concentrados entre as faixas de 30 a 59 anos com 49,3%, e uma significativa presença de jovens até 19 anos (25,3%) e membros mais idosos com idade superior a 60 anos (7,5%). A taxa de analfabetismo é considerada baixa, porém com grande concentração de membros com ensino fundamental incompleto nas faixas etárias mais elevadas, indicando atraso educacional dos mais velhos e a formação educacional mais elevada está relacionada aos mais novos. Identificou-se que os membros residentes mais velhos são casados e dedicam mais tempo e mão de obra a propriedade, os mais jovens são solteiros, podendo constituir vínculo familiar fora do eixo rural, dedicando menos tempo as atividades agrícolas. Existe homogeneidade de variâncias entres as médias de idade e dias dedicados a propriedade entre os homens e as mulheres e indícios de pluriatividade nas unidades estudadas. Constatou-se que 65,9% dos membros residentes não possuem renda extra agrícola, entre os membros com este tipo de renda, (20,4%) a fonte advinda de aposentadorias é a principal, seguida pelas diversas outras funções desempenhadas pelos agricultores fora de sua propriedade que lhes rendem remuneração e 26,7% concentram-se na faixa entre 1 e 2 salários-mínimos que contribuem para a ampliação da renda familiar. Como trabalhos futuros, sugere-se o levantamento das potencialidades locais para a identificação de oportunidades e renda.
O PROCESSO DE MERCANTILIZAÇÃO DA AGRICULTURA FAMILIAR NO ALTO URUGUAI-RS
Authors: Deggerone Zenicléia Angelita , Schneider Sergio
Published: December 2021

Este artigo tem por objetivo apresentar alguns elementos sócio-históricos que exerceram influência no processo de mercantilização dos agricultores familiares na região Alto Uruguai-RS. O estudo desenvolveu uma abordagem qualiquantitativa, tendo sido realizada uma análise descritiva de dados primários, coletados a partir de entrevistas com atores chaves entre janeiro e abril de 2020 e de informações secundárias, obtidas por meio de pesquisas bibliográficas e documentais. Os resultados deste artigo evidenciam que o Estado, por meio da implementação de mecanismos institucionais (leis, portarias, decretos), políticas públicas de comercialização e de crédito, ofereceu condições para que ocorressem a modernização das atividades produtivas e o crescimento da produção agroalimentar, o que resultou na ampliação do processo de mercantilização. Entre as implicações que esse processo social gerou, os agricultores transformaram-se em produtores simples de mercadorias, mas isso não alterou a condição dessa categoria social, uma vez que as normas, as regras e os valores sociais que regem as relações entre os atores sociais no interior dos grupos familiares não desapareceram em razão da intensificação das trocas.

Published: December 2021

Relevance . Treatment of diffuse lesions of the arteries of the lower extremities is often reduced to primary amputation at the hip level, since the healing of trophic ulcers is not guaranteed during arterial reconstruction. Profundoplasty without distal bypass surgery can be considered an alternative method. The aim of this study is to compare the long-term results of distal shunting and isolated profundoplasty in patients with diffuse lesions of the lower limb arteries and trophic ischemic ulcers. Materials and Methods . The study included 86 patients with diffuse lesions of the lower limb arteries. There were 52 (60.4%) men and 34 (39.6%) women. The average age was 67.3 16.8 years. All patients had diffuse lesions of the arteries below the pupar ligament, the state of the lower leg arteries was 5-8.5 points on the Rutherford scale, in all cases there were trophic ulcers. Group 1 included 48 patients who underwent reconstruction of the leg arteries. Group 2 consisted of 38 individuals who had limited intervention with endarcteriotomy from common femoral and deep femoral arteries. Results and Discussion . Amputations at the hip level were performed within a year in 11 (23.4%) patients of group 1 and in 3 (6.3%) patients within 30 days after surgery. Thus, 14 (29.7%) patients lost their limbs. A comparative analysis revealed that the group of patients with amputations had a more severe form of diabetes (p = 0.003), an outflow score on the Rutherford scale (p 0.001), and lower transcutaneous oxygen tension values before and after surgery. Within 12 months after the bypass surgery, the primary patency of the shunts was 65.9% (thrombosis occurred in 16 patients). Conclusion . The preservation of the limb in patients in our study by the end of 1 year after reconstruction is similar regardless of the reconstruction method. Given the minimal invasion during profundoplasty, this operation may be the method of choice for diffuse lesions of the arteries of the lower extremities.

Authors: Zotova Tatjana Yu. , Lukanina Anastasiya A. , Blagonravov Mikhail L.
Published: December 2021

Relevance . The study of the daily dynamics of blood pressure in arterial hypertension both on the basis of the daily index and on the basis of the time load is a relevant task, since, these indicators are associated in the literature with stable changes in the neurohumoral regulation of the cardiovascular system in arterial hypertension . The aim of the study was to compare data of the time load in patients with arterial hypertension , depending on the nocturnal blood pressure profile, with integrative indicators of the activity of the cardiovascular system in the form of a Circadian index, a structural point of blood pressure, double product. Materials and Methods. The study included 72 patients who were treated at the City Clinical Hospital No 13 in Moscow and signed a voluntary consent to participate in the research and the processing of personal data. Inclusion criteria: arterial hypertension. Exclusion criteria: metabolic syndrome, secondary forms of arterial hypertension and concomitant pathology. Depending on the daily index (DI10% and DI10%) patients were divided into 2 groups: 1 group (N= 32): patients with arterial hypertension without nocturnal decrease in blood pressure (non-dippers and night-pickers100%); Group 2 (N = 40): patients with arterial hypertension who had a nocturnal decrease in blood pressure (dippers and over dippers 100%). All patients and members of the control group (N=15) underwent daily monitoring of blood pressure (24-hour Arterial Blood Pressure Monitoring). The data were statistically processed to determine the 5% level of significance of differences (p0.05) (Students test). In the comparative analysis of integrative indicators at day and at night, a variance analysis was applied. Results and Discussion . As a result of the study, it was found that the values of Circadian Index for blood pressure vary depending on the type of night decrease in blood pressure and the blood pressure time load, while daily index and structural point of blood pressure remain on the same level as a reflection of the hemodynamic allostasis existing in both groups. Conclusion. Reflection of the allostatic load on hemodynamics is change of values of double product and of the structural point of blood pressure compared with the control group. These changes are not associated with the peculiarities of the nocturnal blood pressure profile in patients with hypertension without metabolic syndrome.

Published: December 2021

Relevance. Acute bacterial prostatitis is one of the urgent problems in urology. According to the data presented in the literature, the number of men who have been diagnosed with this disease ranges from 10 to 40 %. At the same time, the main etiological factor in the development of this pathology is most often assigned to the bacterial microflora. However, most of the works are devoted to the study of the microflora in chronic prostatitis, and the state of the microflora in acute bacterial prostatitis remains insufficient. The aim of the study is to evaluate the state of prostate secretion microflora in a comparative aspect in healthy individuals and in patients with acute bacterial prostatitis. Materials and Methods. The study included a comparative analysis of microbiological cultures in prostate secretion of 30 people. All examined were divided into two groups: the first included 15 people without established urological pathology, the second - 15 people with an established diagnosis of acute bacterial prostatitis. Results and Discussion. As a result of the study, it was found that when sowing prostate secretion in persons without established pathology, the absence of microorganism growth was not observed in 60 % of observations, while in 40 % of cases, microorganisms growth was obtained. In the group of examined without established urological pathology, the growth of microorganisms of the following was noted: Escherichia coli - in 58 % of observations; Staphylococcus epidermidis - in 10 % of observations; Staphylococcus warnerii - in 6 % cases and Enterobacter spp. - in 26 %. At the same time, the number of detected microorganisms did not exceed 104 CFU/ml. At the same time, the presence of microbial associations was not recorded. In patients with acute bacterial prostatitis, the sterile prostate secret was 13,3 %, and in 86,7 % of people, microflora growth was obtained. Most often, in the group examined with acute bacterial prostatitis, Escherichia coli was obtained - in 45 % of the observations; Klebsiella spp. - in 23 % cases and Proteus spp. - in 19 %. Less often Staphylococcus epidermidis - in 8 % of observations; Enterobacter spp. - 3,2 %. Serratia spp. - 1,1 % and Staphylococcus warnerii - in 0,7 % cases were the least obtained. At the same time, 86 % of observations in this group revealed microbial associations. Conclusion . Comparison of the state of microflora of prostate secretions in healthy individuals and patients with acute bacterial prostatitis revealed that in patients with acute bacterial prostatitis, the absence of inoculated microflora in prostate secretions was 3 times less than in healthy individuals (13.3 % and 40 %, respectively.), and Escherichia coli was the most common microorganism in the group of patients with acute bacterial prostatitis.
Prospects and Challenges In Developing 'Japanese Studies' Program in Bangladesh: Lessons From the University of Dhaka
Authors: Akon Md. Saifullah , Sharmin Dilruba
Published: December 2021

Japanese Studies has entered a booming period in Bangladesh where the growing demand for knowledge on Japan, particularly Japanese development experience, society, and culture, has intensified. Besides, the increasing number of Japanese companies and opportunities to work in Japan so far is conducive to the increasing number of students in the Japanese language. Considering the given facts, academic institutions of Bangladesh need to initiate 'Japanese Studies' programs to produce 'Japanologists’-contextual and transitional expertise. The larger goal of this study is to identify the major prospects and challenges and consider the future directions for the Japanese Studies program. The paper intends to think alternatively beyond the 'ivory tower' mindset of a large number of Bangladeshi students as well as academicians and show the prospects of Japanese Studies with sustainable employment opportunities through industry-academia collaboration. The methods and equipping tools employed in this paper include lexical scrutiny and contextual analysis under the qualitative research method to analyse the current state of knowledge and pedagogical development. Presenting the number of stumbling blocks of the Japanese Studies program in Bangladesh, the paper finally demonstrates the program's future as an academic discipline. It ends with possible suggestions towards success in producing Japanologists to strengthen Bangladesh-Japan bilateral relations.
China and Russia Security Cooperation on Arms Exports Toward the US’ Global Hegemony
Authors: Wiranata Kusuma Sigit Candra , Ngambut Aurelia V. T. , Christina Novelia
Published: December 2021

The purpose of this paper is to analyse China and Russia’s relationship in terms of arms exports between both countries and its implications for the United States (US) using a qualitative method and the conceptual framework of Neorealism: hegemony and security cooperation. China and Russia are two great powers that have maintained close diplomatic ties since the Cold War Era. Both China and Russia cooperate in various sectors, including security. Since the collapse of the SU (USSR), which marked the establishment of post-Cold War Russia, the country has become a major arms exporter to China. This close relationship has dynamically developed in the last few decades. China-Russia security cooperation has been assessed as a security challenge for the US. The security cooperation between China, the new rival for the US since its rising, and Russia, the US’ former superpower rival in the Cold War era, is interpreted as a threat to US domination in the Asia-Pacific. However, this paper concludes that while China and Russia have a close relationship, China can surpass Russia’s military technology. That is why, although these countries relationships are close and Russia does not see China as its primary threat, this does not mean that Russia will let its guard down in facing China’s development. There is a tri-polar power balance between these countries and with the US. The main worry is if two actors get too close, leaving the remaining state isolated. Regardless of the global power equilibrium trajectory, China and Russia will become more closed than the US.
A política das Letras na obra de Luís de Camões / The Politics of Letters in Luís de Camões’ work
Authors: De Brito Matheus Barbosa Morais
Published: December 2021

Os Lusíadas é trivialmente encarado como um épico nacionalista, narrativa “colonialista” que justifica a dominação da África e da Ásia em nome da Fé e do Império. Mas essa recepção tem também suas inflexões históricas. Camões já foi acusado de paganismo, lascívia, vitupério à memória régia, impiedade, má escrita, etc., e até surpreende que já se disse que seu poema “desacredita a Nação Portuguesa”. Lendo atentamente, a montagem d’Os Lusíadas não ignora, por exemplo, a ignomínia do ataque dos marinheiros aos negros da Baía de Santa Helena, nem deixa, para além do velho do Restelo, de acusar a cobiça e ignomínia da mercancia, exprobando o Gama – que é mentiroso, inculto e covarde. O presente artigo oferece algumas coordenadas ético-retóricas para uma compreensão do enlace entre as letras e a política no século XVI, com destaque para a sua figuração na obra de Luís de Camões. Faremos uma leitura de alguns passos d’Os Lusíadas visando a entender dois fundamentais mecanismos de representação que tornam o poema, mais do que um artefato patriótico inócuo, uma particular mensagem: o louvor, como regulativo do “ideal”, e o vitupério, como aplicação a uma situação concreta.
ARTAUD E O MEIO PARA OS DEVIRES-LOUCO
Authors: Lock Farina Diego
Published: December 2021

O presente artigo analisa os agenciamentos entre a obra de Artaud e o desdobramento de alguns de seus conceitos operado por Deleuze no campo do pensamento imanente. Partindo de Pour en finir avec le jugement de dieu e da poética da crueldade, Artaud erige o “Corpo sem órgãos”, que declara combate ao organismo antropocêntrico, em nome da liberdade pré-individual, do fim do juízo, e pela demanda de uma história do impossível na linguagem. Fora e devir, gagueira e esquizofrenia enquanto estilo, encontram em Deleuze singulares problematizações ético-políticas através da literatura como empreendimento de saúde. Nesse intuito, tensionamos sobretudo as leituras de Grossman e Blanchot acerca do silêncio e do sofrimento artauniano com o pensamento sem imagem deleuziano, no sentido de explorarmos as reais metamorfoses que acontecem em meio a esse processo artístico antimimético, não-teleológico, não-identitário e que, enfim, provoca os limites do ontológico, promovendo a multiplicidade no plano da criação.
Digital and electronic transactions against velocity of money

Published: December 2021

The payment system accumulates through an interbank fund transfer system, banking procedures, and a set of instruments that guarantee the circulation of money (Hancock & Humphrey, 1997). The theory of money expressed by Fisher is very striking and different from Marx’s. Marx only emphasizes monetary developments as contemporary capitalism. However, Fisher on the form of money and the function of money in a certain amount (as cited in Ivanova, 2020). The flow of electronic and digital transactions has continued to innovate over the past decade. An important point of this research is to identify electronic transactions and digital transactions against the velocity of money (VoM) in Indonesia. Fisher’s theory of money is applied to this study. Through a quantitative approach, time-series data for 2009–2019 was collected from the Bank of Indonesia and BPS-Indonesia. Multiple linear regression analysis is useful in interpreting the data. As a result, we find electronic transactions measured by credit cards appear to have a negative effect on VoM, but the impact is significant. Meanwhile, debit cards actually have a positive and significant effect on the value of VoM. Interestingly, other empirical results explore the relationship of digital transactions represented by e-money with VoM, where the effect is negative and insignificant. This finding is also very relevant to banking efforts to harmonize and adopt advanced technology in the financial system
Investigations of the through-thickness residual stress distribution during the partial heating roll forming process of square and rectangular hollow steel sections
Authors: Mehari Zelalem Abathun , Han Jingtao
Published: December 2021

With the growing demand for rectangular and square hollow steel sections
in the last few decades, the cold roll forming process has become a
widely acknowledged hollow sections manufacturing method; however,
residual stress generated during the roll forming process is one of the
primary concerns on roll-formed products. In this regard, several
researchers have conducted numerical and experimental investigations of
residual stress distributions on roll-formed steel sections. However,
most of the studies found in the literature have been confined to the
measurement of residual surface stresses. On the other hand,
experimental studies conducted on fatigue and load-carrying capacity of
hollow structural steels have shown that there is indeed a simple
relation between the through-thickness residual stress distributions and
mechanical properties of structures. Thus, this paper employed a proper
numerical modelling procedure using LS-DYNA’s finite element code to
explore through-thickness residual stress distributions generated during
the roll forming process of rectangular and square hollow steel sections
from different material grades. Moreover, a small-scale parametric study
was conducted to explore the effects of the partial heating roll forming
method on through-the-thickness residual stress distributions to satisfy
the growing demand for residual stress-free roll-formed products.
A target capture approach for phylogenomic analyses at multiple evolutionary timescales in rosewoods (Dalbergia spp.) and the legume family (Fabaceae)
Authors: Crameri Simon , Fior Simone , Zoller Stefan , Widmer Alex
Published: December 2021

Understanding the genetic changes associated with the evolution of
biological diversity is of fundamental interest to molecular ecologists.
The assessment of genetic variation at hundreds or thousands of unlinked
genetic loci forms a sound basis to address questions ranging from
micro- to macro-evolutionary timescales, and is now possible thanks to
advances in sequencing technology. Major difficulties are associated
with i) the lack of genomic resources for many taxa, especially from
tropical biodiversity hotspots, ii) scaling the numbers of individuals
analyzed and loci sequenced, and iii) building tools for reproducible
bioinformatic analyses of such datasets. To address these challenges, we
developed a set of target capture probes for phylogenomic studies of the
highly diverse, pantropically distributed and economically significant
rosewoods (Dalbergia spp.), explored the performance of an
overlapping probe set for target capture across the legume family
(Fabaceae), and built a general-purpose bioinformatics pipeline.
Phylogenomic analyses of Dalbergia species from Madagascar
yielded highly resolved and well supported hypotheses of evolutionary
relationships. Population genomic analyses identified differences
between closely related species and revealed the existence of a
potentially new species, suggesting that the diversity of Malagasy
Dalbergia species has been underestimated. Analyses at the family
level corroborated previous findings by the recovery of monophyletic
subfamilies and many well-known clades, as well as high levels of gene
tree discordance, especially near the root of the family. The new
genomic and bioinformatics resources will hopefully advance systematics
and ecological genetics research in legumes, and promote conservation of
the highly diverse and endangered Dalbergia rosewoods.

The article explores labor migration processes in modern Russian school education. The relevance of this research is due to the current shortage of teachers in Russian schools, especially young specialists. The main method was qualitative content analysis of documents, statistical data, and available resources on this issue presented in the scientific articles on this issue. This paper shows that the transitional state of modern Russian society social and cultural transformation has a significant impact on the processes of professional migration. The article reveals the connection between the ongoing social and cultural transformation and the processes of labor migration of Russian teachers and graduates of pedagogical universities, which is a new perspective for considering this issue, since the problem of labor migration has not been examined from this angle.

Authors: Savic Sladjana , Roglic Goran , Avdin Vyacheslav , Zherebtsov Dmitry , Stankovic Dalibor , Manojlovic Dragan
Published: December 2021

Compounds used in the fashion industry effect the water bodies in the vicinity of textile factories, resulting in the visible coloration of surface water. Fe-doped graphite-based in house prepared electrodes were used in the Fenton- -like degradation of Reactive Blue 52 (RB52). The electrodes consisting of high-density graphite in three granulation sizes and three levels of Fe content were characterized using scanning electron microscopy (SEM). The amount of Fe in the electrodes and H2O2 concentration in synthetic textile wastewater were optimized. Additionally, the size of graphite grains was varied to investigate whether it effects the degradation rate. Under only 10 min of electro-Fenton degradation, a system with 10 mmol dm-3 of H2O2 and an electrode made of 7 % of Fe and 70 ?m of granulation size of graphite, degraded over 75 % of RB52, and over 99 % after 40 min of treatment. The obtained results indicate that the proposed approach could be beneficial in the field of novel materials for environmental application and that in house prepared carbon could be an excellent replacement for commercially available supports.
Profit Calculation in a Late 14th Century Sole Proprietorship: The Case of Francesco Datini
Authors: Kuter Mikhail , Baker Charles Richard , Gurskaya Marina
Published: December 2021

This paper examines the Profit on merchandise accounts (a forerunner of the income statement) in a sole proprietorship in Pisa that officially operated between 1386 and 1392, but took several months to finally end its activities, which it did in 1393. The Profit on merchandise account was where the balance on each goods account was transferred when all the items recorded in it were sold. The principal contribution of this paper is the identification of a unique approach to medieval product costing that ensured indirect expenses on merchandise were recovered from customers when sales took place, while earning an average return of over 10 percent on those costs. It also highlights the problems encountered when working with archival material that has deteriorated over time; and presents a research method that reconstructs missing data using the trail to original entries and contra entries recorded in double entry.
Effects of Slab Types on the Seismic Behavior and Construction Cost of RC Buildings
Authors: TUNÇ Gökhan , AZİZİ Abdul Basir , TANFENER Tuğrul
Published: December 2021

Reinforced concrete-framed buildings are commonly preferred to other types of buildings in Turkey. In these types of buildings, a two-way slab with beams, flat, waffle, and ribbed slab types are widely used. In building design, determining the best slab type that will perform well under gravity and lateral loads, with the least cost, is required. However, the proper selection of slab type has generally been overlooked by designers due to the emphasis on other structural members, such as beams, columns and structural walls. For this reason, the structural contribution of floors to building design has not been adequately examined. This shortcoming must be inspected in detail starting from the very first step of the design stage of a building. This study assesses the effects of different slab types on multi-story reinforced concrete buildings by investigating their structural behaviors while trying to optimize their overall cost. For this purpose, a total of 36 structural models were constructed, analyzed, and designed according to the current Turkish Building Codes and Standards. The type of slab system (a two-way slab with beams, flat, waffle and ribbed), the number of floors (10, 20 and 30), and span length (6, 7.5, and 9 m) were selected as the key parameters in these analyses. The buildings were assumed to be office buildings located in a seismically-active zone in Istanbul. The results indicated that a two-way slab with beams was the most economical slab type for 6-meter spans, while the waffle slab was the most economical for spans larger than 7.5 meters. Based on these results, the flat slab was found to be the most expensive slab type in all cases. Out of all slab types, the two-way slab with beams exhibited better earthquake performance, while the waffle and flat slabs provided relatively poor earthquake performances.

Objective

To evaluate the mechanical stability and the proteolytic activity of bonds created by a two-step, etch-and-rinse adhesive applied to cross-linked and air-dried etched dentin.

Methods

Flat dentin surfaces were produced in 64 extracted sound human molars. The dentin was etched with 35% phosphoric acid for 15 seconds, and then the teeth were divided into groups according to the cross-linking solution applied on the etched dentin. Group 1: 5% grape seed extract (GSE), Group 2: 5% glutaraldehyde, Group 3: Gluma Desensitizer, or Group 4: deionized water (control). Solutions were applied for 60 seconds, followed by rinse and blot drying. Then, the teeth were separated into two subgroups where the etched dentin was kept moist or air-dried. The adhesive was applied followed by a composite resin buildup. After 24 hours, the teeth were cut into beams (0.81 mm²) that were tested for microtensile strength immediately or after 12 months of aging in a 37°C saliva-like buffer. Additional teeth (n=32) were bonded as described and cut into 0.5-mm-thick slabs. The slabs were prepared for nanoleakage (scanning electron microscopy) and in situ zymography (EnzChek Protease Assay Kit). Bond strength data were submitted to ANOVA and Tukey tests (α =0.05).

Results

Significant reduction in immediate bond strength (ca 65%) and increase in proteolytic activity was seen when the etched dentin was air dried without previous cross-linking biomodification. Conversely, bond strengths did not differ from those produced on wet dentin when collagen was cross-linked before air drying, irrespective of the solution applied. For both moist and air-dried etched dentin, collagen cross-linking resulted in mechanically stable bonds and reduced proteolytic activity after 12 months of storage.

Conclusion

Bonds produced by the application of a two-step, etch-and-rinse adhesive to cross-linked, air-dried, etched dentin were mechanically stable and revealed reduced proteolytic activity after 1 year of aging.

Published: December 2021

Purpose

The following PICO (Patient/Population, Intervention, Comparison, and Outcomes) question was proposed: “Are retention rates of composite resin restorations in noncarious cervical lesions (NCCLs) when using adhesives considered “gold standard” (OptiBond FL and Clearfil SE Bond) higher than those obtained with other adhesives brands”?

Methods

A search was performed in February 2019 (updated in November 2019) in the PubMed/MEDLINE, EMBASE, LILACS, BBO, Web of Science, Cochrane Library, Grey Literature, and IADR abstracts (1990–2018); unpublished and ongoing trial registries, dissertations, and theses were also searched. Only randomized clinical trials (RCTs) conducted in NCCLs that compared either OptiBond FL or Clearfil SE Bond adhesive with other commercially available adhesives were included. The risk of bias (RoB) was applied by using the Cochrane Collaboration tool. A meta-analysis was performed for retention rates at different follow-up times using a random effects model for both the adhesives. Heterogeneity was assessed with the Cochran Q test and I2 statistics. Grading of Recommendations: Assessment, Development and Evaluation (GRADE) assessed the quality of evidence.

Results

After removal of duplicates and noneligible articles, 25 studies remained for qualitative synthesis, as one study was common to the two adhesives, of which 9 studies were used for the OptiBond FL meta-analysis and 14 for the Clearfil SE Bond meta-analysis. No significant differences were observed for retention rates in follow-up periods of 12–24 months (p=0.97), 36–48 months (p=0.72), or 108–156 months (p=0.73) for OptiBond FL; and for 12–24 months (p=0.10) and 36–48 months (p=0.17) for Clearfil SE Bond. A significant difference was only found for OptiBond FL at 60–96 months (p=0.02), but only three studies were included in this meta-analysis.

Conclusions

The evidence from available RCTs conducted in NCCLs that compared OptiBond FL or Clearfil SE Bond does not support the widespread concept that these adhesives are better than any other competitive brands available in the dental market.

Fundamental physiologic concepts of venous hemodynamics and systemic venous return
Authors: Markovic Jovan N
Published: December 2021

Understanding the nominal venous anatomy and venous hemodynamics is the first and fundamental step in understanding the pathophysiology of venous disorders. Over the last two decades, significant effort has gone into improving the management of chronic venous disorders resulting in substantial improvement in the management of patients affected by venous insufficiency. Given the continuity of the venous system especially pertinent to the relationship between thoracic, abdominal, pelvic, and infrainguinal venous anatomy, combined with the increasing knowledge we gained regarding hemodynamics of the venous system it is imperative that a comprehensive approach to venous disorders is undertaken that evaluates venous system as a continuum rather than an approach that would evaluate only isolated venous territory affected by a specific venous disorder. Understanding of venous anatomy and physiology, as the basic components for venous hemodynamics, is an essential step to gain insights into venous return concepts, initially described by Dr. Guyton. Dr. Guyton's model represents a fundamental and one of the most significant advancements in our understanding of venous return. This manuscript details essential domains of hemodynamics, which can be useful for validation of our current understanding of systemic venous return.

This paper shows the prospect to find industrial-scale hydrogen accumulations in riftogenic structures of platforms using the example of the Dnieper-Donets Aulacogene, located in the southern part of the East European Platform. Within the Dnieper-Donets Depression, geological and geophysical methods indicate a significant number of deep faults and ring structures of volcanogenic and explosive origin promising increased hydrogen content. Possible locations of the most propitious areas of hydrogen concentration are associated with faults in rift systems and their nearest margins, as well as with explosive and volcanogenic ring structures with signs of modern activation. At a fine-grained level, the prospectivity of the area is determined not only by the specified structural relationship, but also by the set of geophysical characteristics (thermal, seismic, gravity, electrical conductivity, magnetic) and the corresponding geological and hydrogeological parameters. Areas for further more detailed investigations within the Sribne and other ring structures, Southern Near-Edge Fault, Northern Near-Edge Fault were identified based on the data on geological and geophysical materials, satellite images, and field work. We defined high-priority and low-priority territories. Areas for initial investigations using satellite images, gas sampling (hydrogen, helium, methane, etc.), primary geophysical surveys (with evaluation of intermediate reservoirs and cap rocks) were identified. The primary results can be used to plan pilot shallow drilling and wells sampling. The areas for priority deeper drilling and sampling are selected by the sum of results obtained and data comparison. The paper presents the results obtained 30 km east of Kyiv as an example of field assessment of H2 degassing in a local depression. The results show that hydrogen concentrations at depths of 0.45 to 1.5 m are near zero outside the local depression. The maximum values of H2 concentration (up to 3300 ppm 1.5 m deep) are characteristic of the point inside the depression.
O ENSINO DE QUÍMICA COMO UNIDADE DIALÉTICA ENTRE OS NÍVEIS MACROSCÓPICOS E SUBMICROSCÓPICOS: para além do triângulo do Johnstone
Authors: De Souza Silva Caio , Da Silva Messeder Neto Hélio
Published: December 2021

No ensino de química há uma adoção quase que hegemônica das ideias do professor Alex Johnstone sobre os três níveis representacionais do conhecimento químico, os quais ficaram conhecidos como triângulo de Johnstone: macroscópico, submicroscópico e simbólico. Nesse sentido, muitos trabalhos tomam essa ideia  como embasamento quase que natural e focalizam o debate na forma de torná-lo didático, deixando em segundo plano discussões epistemológicas necessárias. No entanto, este trabalho tem como objetivo contribuir com a crítica ao triângulo de Johnstone e promover uma discussão que gere uma nova compreensão da realidade sobre os níveis do conhecimento químico através da perspectiva do materialismo histórico-dialético e da psicologia histórico-cultural. Esses fundamentos nos levaram a propor que a química se fundamenta na unidade dialética entre dois níveis da realidade, o macroscópico e submicroscópico, mediados pela representação.  Além disso, apontamos princípios da prática pedagógica para que a nossa concepção pudesse ganhar materialidade para o campo do ensino de química.
