Authors: Rahardjo Sutio , Wayanti Sri , Suparji Suparji
Published: August 2022

BACKGROUND: Based on the manual book Village Midwife, published by the Ministry of Health of the Republic of Indonesia in 2008, one of the visions of empowering midwife is to reduce the case of malnourished toddlers and got diarrhea, so screening is essential to do.

AIM: This research analyzes the efforts to control the incidence of malnourished toddlers based on the analysis to management function of midwife performance in the screening of malnourished toddlers in Bangkalan Regency.

MATERIALS AND METHODS: This is a descriptive research. The research was conducted in Bangkalan Regency. Research participants consisted of 376 midwives located in 22 Community Health Centers in Bangkalan Regency. The sampling technique was proportional random sampling, with a sample size of 331 midwives. The data collection tool is in the form of a questionnaire, before being used, the validity and reliability tests are carried out, the results are valid and reliable. Data analysis used descriptive statistics, the form of frequency distribution and percentage.

RESULTS: Supervision on the parameters that most take effect to the midwife performance in the screening of malnourished toddlers. Moreover, then, the variables of the planning function and the mobilization function were affect the performance of midwife in screening malnourished toddlers in Bangkalan Regency. While the variable of the organizing function does not affect to the performance of midwife in malnourished screening.

CONCLUSION: To improve the performance of midwife in screening malnourished toddlers in Bangkalan Regency, good cooperation and coordination is most needed between the Health Office, related organizations, the community, and parents/families of toddlers as well as important officials at Bangkalan Regency. Especially to the health-care workers to announced information and socialized about the health of toddlers to the community and parents/families. So that the incidence of malnourished toddlers can be detected early for follow-up.
Case Report Multiple Sclerosis
Authors: Yolanda Ike Retno , Ritarwan Kiking
Published: August 2022

BACKGROUND: Multiple sclerosis (MS) is an autoimmune disease in the form of chronic inflammation of the CNS. This disease is mediated by autoreactive lymphocytes that can cross the blood-brain barrier and thus enter the CNS and cause inflammation. Chronic demyelinating CNS lesions characterize multiple sclerosis, and immunity to myelin is involved. This disease predominantly attacks the brain, spinal cord, and optic nerve. The diagnosis of MS is made clinically, and there is no single definitive test for MS. The key to diagnosis is Dissemination in Space (DIS) and Dissemination in Time (DIT). Magnetic resonance imaging has become an essential part of the diagnosis of MS after clinical.

CASE REPORT: Here, we report a case of a 31 year-old woman with the main complaint of weakness of four extremities accompanied by a decreased vision and impaired urination and bowel movement. The patient was diagnosed with suspected MS.

CONCLUSION: The patient subsequently was treated with intravenous steroids and, on the routine follow-up found marked clinical improvement.
Acrocalymma chuxiongense sp. nov., a new species of Acrocalymmaceae (Pleosporales) on leaves of Quercus
Authors: Liu Yu-Wei , Zeng Xiang-Yu
Published: August 2022

In Huafo Mountain, Mouding, Yunnan Province, China, we found black protrusions on the leaf surface of Quercus plants. The collection which we identified as Acrocalymma chuxiongense sp. nov., a new species of Acrocalymmaceae (Pleosporales) is characterised by dome-shaped ascomata, bitunicate asci with pedicel furcate and an ocular chamber and hyaline, obovoid to ellipsoid, 1-septate ascospores.

Morphologically, this species is typical with obovoid to ellipsoid, larger ascospores than other known species in Acrocalymma. Phylogenetic analysis also showed that it represents a distinct clade, distant to any other species of Acrocalymma. Therefore, we introduce it as Acrocalymma chuxiongense, a new species of Acrocalymmaceae. This study is adding to the current situation where there are very few species and lack of teleomorph characteristics.

Published: August 2022

Following recent mimosoid phylogenetic and phylogenomic studies demonstrating the non-monophyly of the genus Albizia, we present a new molecular phylogeny focused on the neotropical species in the genus, with much denser taxon sampling than previous studies. Our aims were to test the monophyly of the neotropical section Arthrosamanea, resolve species relationships, and gain insights into the evolution of fruit morphology. We perform a Bayesian phylogenetic analysis of sequences of nuclear internal and external transcribed spacer regions and trace the evolution of fruit dehiscence and lomentiform pods. Our results find further support for the non-monophyly of the genus Albizia, and confirm the previously proposed segregation of Hesperalbizia, Hydrochorea, Balizia and Pseudosamanea. All species that were sampled from section Arthrosamanea form a clade that is sister to a clade composed of Jupunba, Punjuba, Balizia and Hydrochorea. We find that lomentiform fruits are independently derived from indehiscent septate fruits in both Hydrochorea and section Arthrosamanea. Our results show that morphological adaptations to hydrochory, associated with shifts into seasonally flooded habitats, have occurred several times independently in different geographic areas and different lineages within the ingoid clade. This suggests that environmental conditions have likely played a key role in the evolution of fruit types in Albizia and related genera. We resurrect the name Pseudalbizzia to accommodate the species of section Arthrosamanea, except for two species that were not sampled here but have been shown in other studies to be more closely related to other ingoid genera and we restrict the name Albizia s.s. to the species from Africa, Madagascar, Asia, Australia, and the Pacific. Twenty-one new nomenclatural combinations in Pseudalbizzia are proposed, including 16 species and 5 infraspecific varietal names. In addition to the type species Pseudalbizzia berteroana, the genus has 17 species distributed across tropical regions of the Americas, including the Caribbean. Finally, a new infrageneric classification into five sections is proposed and a distribution map of the species of Pseudalbizzia is presented.
Reinstatement of Ticanto (Leguminosae-Caesalpinioideae) – the final piece in the Caesalpinia group puzzle
Authors: Clark Ruth P. , Jiang Kai-Wen , Gagnon Edeline
Published: August 2022

A recent molecular phylogenetic analysis of the Caesalpinia group demonstrated that it comprises 26 genera, but the recognition of a putative 27thgenus,Ticanto, remained in doubt. This study presents a phylogenetic analysis of ITS and five plastid loci revealing a robustly supported monophyletic group representing the Ticanto clade, sister to the morphologically distinct genusPterolobium. Based upon this evidence, along with a morphological evaluation, the genusTicantois here reinstated. Descriptions are provided for all nine species ofTicanto, together with a key to the species, maps, and colour photographs. Nine new combinations are made:Ticanto caesia(Hand.-Mazz.) R. Clark & Gagnon,T. crista(L.) R. Clark & Gagnon,T. elliptifolia(S. J. Li, Z. Y. Chen & D. X. Zhang) R. Clark & Gagnon,T. magnifoliolata(Metcalf) R. Clark & Gagnon,T. rhombifoliaR. Clark & Gagnon,T. sinensis(Hemsl.) R. Clark & Gagnon,T. szechuenensis(Craib) R. Clark & Gagnon,T. vernalis(Champion ex Benth.) R. Clark & Gagnon andT. yunnanensis(S. J. Li, D. X. Zhang & Z.Y. Chen) R. Clark & Gagnon. The final major question in the delimitation of segregate genera from withinCaesalpiniasensu latoand the Caesalpinia group is thus resolved.
Osodendron gen. nov. (Leguminosae, Caesalpinioideae), a new genus of mimosoid legumes of tropical Africa
Authors: Koenen Erik J. M.
Published: August 2022

The genus Osodendron is here newly described to accommodate three species and one subspecies of African mimosoid legumes. These taxa have previously been included by several authors in Albizia, Cathormion and/or Samanea, but they have been shown to be phylogenetically unrelated to any of these, being instead the sister-group of the recently described Neotropical genus Robrichia, which is similar in vegetative morphology and especially its very similar indumentum, but is decidedly different in pod morphology. A taxonomic treatment of the three species in the genus is presented, with species descriptions, photographs, distribution maps and an identification key. The type species Osodendron altissimum (Hook. f.) E.J.M. Koenen occurs in swamp and riverine rainforest and gallery forests, with the typical subsp. altissimum widespread across tropical Africa, while Osodendron altissimum subsp. busiraensis (G.C.C. Gilbert) E.J.M. Koenen is only known from the Busira river catchment in the western part of the Democratic Republic of Congo. Of the other two species, Osodendron dinklagei (Harms) E.J.M. Koenen is a common tree of rainforest and the forest-savannah transition including semi-deciduous and secondary forest as well as gallery forest and is restricted to Upper Guinea and the similar, but vegetatively more variable Osodendron leptophyllum (Harms) E.J.M. Koenen occupies comparable vegetation types in Lower Guinea and extends marginally into the Sudanian and Zambezian savannahs in gallery forest.
Psychosocial Stressors of COVID-19– and Non-COVID-19–Dedicated Nurses: A Comparative Study

The current comparative study sought to identify psychosocial stressors of corona-virus disease 2019 (COVID-19)–dedicated (
n
= 110) and non-COVID-19–dedicated (
n
= 118) nurses (herein referred to as COVID nurses and non-COVID nurses, respectively). Data were collected online from October 20, 2020, to April 1, 2021. Significant predictors of mental health for COVID nurses were purpose/meaning (β = −0.32,
p
< 0.001), perceived stigma (β = 0.25,
p
= 0.001), perceived work environment improvement (β = −0.22,
p
= 0.004), and absolute work intensity (β = 0.26,
p
= 0.004). For non-COVID nurses, predictors were purpose/meaning (β = −0.34,
p
< 0.001) and absolute work intensity (β = 0.26,
p
= 0.003). It is necessary to develop programs and policies that support the mental health of nursing staff. Administrative efforts should be made to create a work environment that allows nurses to focus on their work during health crises, such as the COVID-19 pandemic. Nursing staff should be supported so that appropriate working hours are maintained and breaks are guaranteed. [

A method to calculate the number of dynamic HDFS copies based on file access popularity
Authors: Cao Xi-yue , Wang Chao , Wang Biao , He Zhen-xue
Published: August 2022

HDFS heterogeneous clusters usually have multiple storage media at the same time. How to efficiently read and write file copies and reasonably use various storage media is a problem to be solved. Dynamically adjusting the number of copies is important in HDFS, which can solve the problem of accessing a large number of hot files at the same time and improve the efficiency of cluster services. A method is introduced to calculate the number of dynamic HDFS copies based on file access popularity in this paper. Firstly, an algorithm was proposed to predict file popularity based on the cuckoo search optimization Markov model. The unbiased grey model is used to predict the accessing file's popularity at the next moment according to the recent access of the file. The cuckoo search is used to optimize the Markov model, and the prediction error is corrected. Then, the calculation method of the number of copies is designed based on the prediction of the popularity of the file to be accessed and the availability of the node. The experiment shows that the proposed method has a high fitting degree with the actual value, and the MAPE is 3.08%, and it is the smallest, compared with several commonly used prediction models. In CloudSim4.0 simulation platform, multiple users write 10 files to the cluster at the same time, and the change number of copies is calculated according to the predicted value at the next moment, so as to improve the user access efficiency.
De Didot (an III) à Laboulaye (1879) : l’avènement philosophique de Montesquieu
Authors: Volpilhac-Auger Catherine
Published: August 2022

À la fin du XVIIIe siècle, l’édition des œuvres de Montesquieu relève encore de la polémique, avec l’édition de 1759 (remarques « anonymes » de Luzac) puis celle de Didot (1795), qui prétend s’appuyer sur Helvétius, ou de l’hagiographie, avec l’édition Plassan (1796-1797). Le XIXe siècle développe une pratique commercialement utile, mais aussi intellectuellement intéressante, qui consiste à juxtaposer les notes critiques extraites de divers commentateurs : l’œuvre devient ainsi matière à débat, en un temps (après la Restauration) où Montesquieu revient en grâce, tandis que se multiplient les éditions qui ne peuvent guère se différencier que par cet apparat critique hétéroclite. Les Œuvres complètes dues à Laboulaye (1875-1879) marquent une véritable rupture : se conjuguent la formation juridique et les positions politiques de ce partisan d’une monarchie constitutionnelle, mais surtout le désir d’entrer dans la pensée de Montesquieu plutôt que de la critiquer superficiellement, pour mieux y introduire le lecteur. C’est à ces conditions que l’œuvre ainsi éditée peut devenir proprement philosophique.
Un livre « utile en ce moment » : l’édition de Buffier comme pratique idéologique au XIXe siècle
Authors: Rouquayrol Louis
Published: August 2022

Le Traité des premières vérités (1724) de Claude Buffier connaît, au XIXe siècle, deux éditions. L’une, d’inspiration catholique, insiste sur la continuité entre la philosophie du sens commun du jésuite et le principe d’autorité de Félicité de Lamennais. L’autre, qui émane de l’école cousinienne, insiste au contraire sur la dette de l’école écossaise du Common Sense à l’égard de l’œuvre de Buffier. L’une et l’autre cherchent à dissocier Buffier de la philosophie dont il se sentait peut-être le plus proche, mais qui préfigure à bien des égards tous les excès (sensualisme, matérialisme, athéisme) du XVIIIe siècle que catholiques et cousiniens combattent : celle de Locke. Par leurs défauts, ces deux éditions ne nous apprennent pas grand-chose sur le Traité des premières vérités, mais disent en revanche beaucoup des luttes idéologiques dont le XIXe siècle a été le théâtre.
Les éditions des philosophes écossais par Théodore Jouffroy. Mouvement historique et réforme philosophique
Authors: Clauzade Laurent
Published: August 2022

Le travail éditorial de Théodore Jouffroy s’est exclusivement attaché à présenter et à traduire les auteurs écossais : les Esquisses de philosophie morale de Dugald Stewart, et les Œuvres complètes de Thomas Reid. Cette étude essaie de déterminer le sens de ce travail, que Jouffroy ne concevait pas comme une contribution à l’histoire de la philosophie, mais plutôt comme une réflexion sur la nature et l’organisation des sciences philosophiques. La première partie de cette étude décrit le contexte historique complexe dans lequel ces éditions ont été élaborées. La seconde partie montre, à partir de la préface aux œuvres complètes de Reid, comment les rapports entre Jouffroy et l’éclectisme cousinien ont évolué.

Published: August 2022

The internet of things (IoT) is a revolutionary technology that links living and non-living devices all around the world. As a result, the frequency of cyber-attacks against IoT deployments is expected to rise. As a result, each system must be absolutely secure; otherwise, consumers may opt not to utilize the technology. DDoS assaults that recently attacked various IoT networks resulted in massive losses. There is only one way to detect stolen data from software and malware on the IoT network that is discussed in this chapter. To categorize stolen programming with source code literary theft, the tensor flow deep neural system is offered. To communicate raucous information while simultaneously emphasizing the value of each token in terms of source code forgery, tokenization, and measurement, the malware samples were gathered using the Malign dataset. The results show that the methodology proposed for analyzing IoT cyber security threats has a higher classification efficiency than current methodologies.

Published: August 2022

Sustainability has become the global need for survival in all scopes due to financial development's side effects that have resulted in environmental destruction. The world leaders have proposed green banking (GB) to reduce carbon footprints from banking operations by promoting paperless financial services based on technology. However, the adoption of GB remains unsatisfactory in the UAE. The study attempts to investigate the determinants of consumers' adoption of GB technology. An exploratory sequential mixed-method approach is employed. The qualitative analysis identified six new challenges facing customers' intention adoption of GB technology: customer awareness, personal innovativeness, bank reputation, security and privacy, system quality, and government support. The preliminary qualitative findings are mostly confirmed by quantitative study whereby customer awareness, personal innovativeness, system quality, and bank reputation significantly impact customers' intention to adopt GB technology. The discussions and implications of these findings are further elaborated.

Green Entrepreneurship and Sustainable Development
Authors: Chandel Tarana Afrin
Published: August 2022

The environmental problems and employment crises throughout the world have been growing. Economic growth is one of the key parameters for economic policies expected for beneficial effects having good impact on the employment and economic well-being. Changes are required and need to find solutions for the problem instead of creating. These changes affect the environment while facilitating industries/business. To overcome the environmental hazard, green entrepreneurship came to light. The concept of green entrepreneurship came into existence from environmental hazards such as pollution, global warning, depletion of ozone layer, and climatic changes occurring due to disturbance within the ecosystem. This study also aims to analyze the relationship between entrepreneurship, transformation, and green development along with the relation between social, traditional entrepreneurship, and in-between institutions and industries.
Social Entrepreneurship Through Innovations in Agriculture
Authors: Khan Shad Ahmad , Magd Hesham , Al Shamsi Ibrahim Rashid , Masoom Kaneez
Published: August 2022

The social entrepreneurs consider solving the social problem first rather than minting profits. As the world today is suffering from the problem of rising population, the food demands are destined to rise in the times to come. The shrinking arable land, less availability of fresh water, concentration of population in towns and cities, etc. are becoming a threat to the agriculture sector. Thus, the agriculture sector requires innovative practices that at times comes with cost. Entrepreneurship with an objective of minting profit might escalate the price of the agricultural produce, and being a primary sector, it might further lead to inflation in other sectors as well. To these issues, social entrepreneurship appears to be a potential solution that has been discussed considering literature and reports in this chapter.
Cyberbullies and Cyberpunks, Oh My
Authors: Shin Songyon , Shadwick Joshua T. , Sobba Kristen N. , Radu Monica Bixby
Published: August 2022

For decades, cyberbullying has been acknowledged as a social phenomenon that poses adverse effects on victims. Scholarship generally defines cyberbullying as repeated behaviors that intend to harm the victims. Prior studies aimed at investigating cyberbullying and victimization patterns among juveniles. Furthermore, risk factors, which increase the likelihood of cyberbullying engagement, had been revealed in several different studies. While there are consistent findings regarding the negative outcomes of cyberbullying, the trends are somewhat obscure due to inconsistent methodology. Furthermore, despite cyberbullying being a domestic and international issue, prior research practices have limited generalizability across samples. These limitations led to inherent gaps in the literature, which ultimately hinders a comprehensive understanding of cyberbullying. Thus, the ultimate purpose of this chapter is to provide both domestic and international reviews regarding cyberbullying engagement. By doing so, this chapter will navigate an in-depth analysis of cyberbullying worldwide.

Published: August 2022

The development of new information technologies has led to new forms of violence between adolescents and young people, frequent users of social networks, chats, and e-messages. Thus, this chapter aims to clarify the concept of cyberbullying and characterize this problem by reflecting on similarities and differences of traditional bullying and its typologies and presenting some prevalence data in different countries, namely during pandemic situation. The authors intend to characterize the participants and roles played in this problem, also reflecting on the consequences for them in the short and long term with an emphasis in the consequences on mental health. The main risk and protection factors of a biopsychosocial nature will be explored considering that this phenomenon is complex and dynamic. Subsequently, preventive strategies will be presented at school and family levels to foster more proactive than reactive responses to the fight against cyberbullying. Finally, some empirically validated intervention strategies stand out.
COVID-19 Misinformation and Polarization on Twitter
Authors: Godard Rebecca , Holtzman Susan
Published: August 2022

This study investigated polarization on Twitter related to the COVID-19 pandemic by examining tweets containing #Plandemic (suggests the pandemic is a hoax) or #StayHome (encourages compliance with health recommendations). Over 35,000 tweets from over 25,000 users were collected in April 2020 and examined using sentiment and social network analyses. Compared to #StayHome tweets, #Plandemic tweets came from a more tightly connected network, were higher in negative emotional content, and could be sub-divided into specific categories of misinformation and conspiracy theories. To evaluate the stability of users' COVID-related perspectives, the prevalence of pro- and anti-mask sentiment was measured in same users' tweets approximately four months later. Results revealed substantial stability over time, with 40% of #Plandemic users tweeting anti-mask hashtags compared to just 2% of #StayHome users. Findings demonstrate COVID-related polarization on Twitter and have implications for public health interventions to quell the propagation of misinformation.

Crisis Communication in the Age of Social Media and the Case of Dairy Khoury
Authors: Zammar Nisrine
Published: August 2022

The use of social media platforms has become an essential part of today's protocol of reacting to any sudden crisis, due to their interactive nature which allows them to reach vast and heterogeneous audiences. This makes them the right tool that enables the organizations to spread their messages efficiently. Any failure in responding adequately on social media level, would allow rumors and negative contents to circulate uncontrollably, affecting the organizational reputation and recovery. Therefore, the main purpose of this paper is to provide a clear understanding of the crisis communication strategy adopted by Dairy Khoury, a Lebanese firm, on social media, at a time when the new power of social media had not yet been fully measured and estimated. The author will highlight the necessity of a preset crisis communication strategy and the use of social media platforms while dealing with crisis.
Enhancing Emergency Communication With Social Media
Authors: Grace Rob , Kropczynski Jess , Pezanowski Scott , Halse Shane , Umar Prasanna , Tapia Andrea
Published: August 2022

Local social media users share and access critical information before, during, and after emergencies. However, existing methods can identify local social media users only after an emergency has occurred, and only then discover a small proportion of users sharing information in a geographic area. To address these limitations, we introduce the method of Social Triangulation to identify local social media users who access community information before an emergency in order to develop emergency communications strategies that contribute to community resilience. Social Triangulation identifies local users vis-à-vis the community organizations they curate within their social networks and, as a result, helps reveal the information infrastructure of a community. Consequently, social triangulation can inform emergency communications planning by identifying “filter bubbles” among social media users loosely embedded in an information infrastructure, as well as community influencers who are well-positioned to redistribute official information during an emergency.
Affording Twitter in Emergency Situations
Authors: Mirbabaie Milad , Amojo Ireti , Stieglitz Stefan
Published: August 2022

This study focuses on Twitter affordances and sense-making outcomes during a single emergency situation. By using an interpretive affordance lens, this study aims to assess rumors as influencers of sense-making during the 2017 Manchester terrorist attack. The authors combined a quantitative network analysis with a qualitative content analysis to assess the role of rumors during the emergency management after the attack. This study provides argumentative grounds for the notion of sense-making as a consequence of affording social media and builds on prior research to place sense-making as a cognitive process within the affordance concept. The authors emphasize new potentials to prevent or control rumors on social media for practitioners and contribute insights to rumor research. Namely, the authors contribute a novel perspective of rumors and their role during emergency management on social media.

Authors: Santos Rodrigo Otávio dos
Published: August 2022

Esse artigo pretende discutir questões acerca da Educação permeada pelas novas redes sociais que estão permanentemente em contato com os estudantes. Portanto, nosso objetivo principal é analisar de que forma os algoritmos, o engajamento e as redes sociais afetam os indivíduos e, mais especificamente, os estudantes. Para tanto, primeiro verificamos as características dos algoritmos, discutindo o que são, qual sua influência no cotidiano, o problema do julgamento arbitrário e de seu formato de caixa preta indecifrável. Adiante, analisamos as redes sociais e o processo de engajamento. Discutimos o que são essas redes, sua influência no mundo contemporâneo, a falta de filtro em postagens e a característica de tela opaca. Também analisamos a questão capitalista de que apenas uma rede de cada tipo pode sobreviver no mercado, além das consequências de um engajamento forçado, os efeitos das interações e as relações com notícias falsas ou teorias da conspiração, bem como a hierarquia entre homem e máquina nessa configuração. Por último, refletimos sobre o processo educacional no qual apresentamos questões como a concentração dos discentes, a dificuldade de triagem da informação correta e a função curadora do professor. Nossa base metodológica consiste em pesquisa bibliográfica e exploratória, com a finalidade de ampliar a discussão. Nosso principal resultado é justamente o debate em torno do tema, buscando apresentar elementos para uma melhor compreensão do fenômeno, tentando com isso fomentar novas possibilidades de entendimento desses elementos e uma melhor relação ensino-aprendizagem no mundo conectado por redes sociais e seus algoritmos. A principal conclusão que podemos tirar é que as redes sociais imbricadas na sociedade influenciam por demais a educação e as formas como jovens aprendem, modificando alguns elementos no cerne da educação, e que são muitos os desafios postos e vindouros, e que cabe aos profissionais da educação conhecer a máquina para não ser sobre pujado por ela.
Pode Maria falar? Um estudo interseccional do conto “Maria”, de Conceição Evaristo
Authors: Azevedo Karen Juliana de Souza , Santos Júnior José Rosa dos
Published: August 2022

O presente trabalho tem como objetivo analisar o conto Maria, de Conceição Evaristo, pela ótica do conceito de interseccionalidade, a partir de Kimberlé Crenshaw (1989) e Carla Akotirene (2019), assim como do conceito de subalternidade, proposto por Spivak (2014). A personagem homônima do conto Maria, de Conceição Evaristo, é uma representação análoga do que tais autoras discutem sobre a identidade da mulher negra ser complexa e relacional com os aspectos de raça e de gênero e não uma coisa ou outra. Assim, Maria performatiza uma complexidade, silenciada e inclusa nos ditames da subalternidade, cuja voz não pode ser ouvida. Na análise do conto de Conceição Evaristo, fundamentada nos conceitos de Akotirene, Crenshaw, e Spivak, pode-se verificar como a personagem Maria e, consequentemente, a obra engendram problemáticas recorrentes na sociedade brasileira, como o silenciamento de sujeitos subalternos, principalmente da mulher preta. Assim, a importância deste artigo se dá pela sua contribuição aos estudos interseccionais na literatura afro-brasileira de autoria feminina

This study aimed to evaluate the influence of adding plastic bottle fibers to soil-cement mixtures and the possible improvements generated by the addition of a blend of two types of additives, namely, additive 1 (waterproofing improver) and additive 2 (adhesion enhancer), in the compactability and shear strength parameters of soil-cement-plastic fiber mixtures, considering a tropical residual soil. The fibers used in this study are made of Polyethylene Terephthalate (PET), produced from soft drink bottles, and added to the soil with 2 mm width and 1 cm length, in the content of 1% in relation to soil dry mass. Also, contents of 3% and 5% Portland cement, in relation to soil dry mass and two additives, additive 1 at a ratio of 0.25 kg m-³ dry soil and additive 2 at a ratio of 0.60 kg m-³ dry soil, were used to evaluate the possible effect of these variables on the investigated engineering behavior parameters. The compaction results indicated that the inclusion of PET fibers in soil-cement mixtures tends to decrease the maximum dry unit weight compared to fiber-free mixtures. Also, if compared to soil-cement-fiber mixtures, the incorporation of additives to soil-cement-fiber composites resulted in higher values of maximum dry unit weight and lower values of optimum moisture content, but still maintaining values lower than obtained for compacted soil. Results of the direct shear test showed enhanced shear strength with the addition of fibers to soil-cement, for both the parameter of cohesion and the internal friction angle of the material in comparison to fiber-free composites, which demonstrates the potential application of these composites in geotechnical works.

A growing demand for advanced composite materials as well as diverse design requirements offering significant weight savings in comparison to conventional materials have all contributed to a growing interest in composite materials. This review paper is focused on Powder Metallurgy (P/M) process to fabricate magnesium based metal matrix composites. The excellent oxidation and corrosion resistance and low density of Silicon carbide have made it a popular material even at very high temperatures. Despite their very high specific strength, magnesium matrix composites possess excellent cast ability, good damping capabilities, and greater machinability. Therefore, this review paper discusses the importance, fabrication, and properties of magnesium matrix composite materials for industry applications. An examination of the properties of recently produced magnesium matrix composites by various researchers is presented in this review paper.

The increase in the production and utilization of plastics has created a never-ending problem of plastic waste. Developing countries face challenges with plastic waste disposal that in due process negatively impacts the environmental ecosystem. That notwithstanding, it suffices to mention that most developing countries have poor road networks that pose a burden towards smooth economic and social development. The problem is further exacerbated by the limited availability of bitumen which is usually imported but also has environmental concerns. It is against this background that we proposed alternative binders from plastic waste which can help developing countries to manage plastic waste as well as build road networks, thereby leading to sustainable development. We explored the 80/100 penetration grade bitumen modification (Penetration grade 85 and Softening temperature 46°C) using polyethylene terephthalate (PET) waste (2 – 12%) and lignin (0.2%) as a crosslinking agent by weight for every PET waste – Bitumen sample. The research showed that Plastic waste and lignin improved the performance of bitumen. The modified bitumen with 10% waste PET and 0.2% lignin enhanced the softening point and penetration points to 55°C and 46, respectively; hence the incorporation of PET and lignin provided better properties compared to the neat bitumen.

In this scientific study, the main properties of structurally inhomogeneous materials are predicted by computer modelling methods. The automatic combination of a scanning microscope and a program cell makes it possible to view the procedure in detail before and after etching with the necessary increase in resolution. Based on the results obtained, we constructed a graphical dependence of the particle sizes of 40 XН steel on the iterative process, and also studied in detail the procedure for the effect of different particle sizes on porosity. We modelled 2D and 3D drawings of the PRT – 7 shaft part. We justified the predicted number of properties, in particular: porosity, particle shape, grain size, microstructure of the sample surface, pre-etching process, post-etching process, as well as the main advantages of the iterative process.

This case report highlights our experience in managing two cases of acute lower limb ischemia with simultaneous acute coronary events. One patient was detected with acute ST-elevation myocardial infarction while being evaluated for acute lower limb ischemia and another patient had NSTEMI with acute left ventricular failure and delayed presentation of acute lower limb ischemia. Both had good outcomes.
Ultrasound-Guided Thrombin Injection of a Pseudoaneurysm with Concomitant Deep Vein Thrombosis

Published: August 2022

The formation of a pseudoaneurysm (PSA) is one of the most common complications following arterial catheterization. These pseudoaneurysms have the potential to cause life-threatening complications. One such extremely uncommon complication is the development of deep vein thrombosis (DVTs). Successful treatment of a PSA can be hindered in patients receiving anticoagulants and special considerations are necessary in such cases. We present a 70-year-old female who developed a postarterial catheterization PSA which was treated with Ultrasound-Guided Thrombin Injection (UGTI) while the patient was receiving apixaban for treatment of a PSA-induced DVT. Peri-procedural imaging helped correctly identify this complex pathology, guide thrombin injection, and observe in real-time instantaneous thrombosis of the PSA while confirming adjacent femoral artery patency. Given the risk of associated complications, patients with a PSA who are receiving anticoagulation should undergo an UGTI for PSA closure. Anticoagulation may cause difficulty in achieving complete thrombosis of PSAs, but recent research has suggested that UGTI remains the preferred method with high overall success rates. Patients receiving anticoagulation undergoing this procedure may benefit from serial postprocedure duplex scans to assess for incomplete PSA closure, thrombosis, or recurrence.

Background:

Anastomotic pseudoaneurysm affecting arteriovenous fistula created for hemodialysis is an unusual and catastrophic complication. There is lack of clinical data in literature about its incidence and management.

Aims and Objectives:

To study the incidence and understand the aetiology of anastomotic pseudoaneurysm of arteriovenous fistula (PA-AVF) occurring in first six months after surgery.

Materials and Methods:

Cohort study based on retrospective analysis of three-year data of case-series of PA-AVF occurring in first six months after AV fistula creation for hemodialysis.

Results:

Among the 283 AV fistula surgeries (215 distal forearm radio-cephalic AVF and 68 brachial artery or cubital region AVF), 7 patients (2.4%) developed PA-AVF within 1 to 8 weeks after AV fistula surgery. Over-extended dependence on non-cuffed hemodialysis (HD) catheter was a common factor among patients developing this complication. All the patients had a prolonged stay (34 to 75 days) of non-cuffed HD catheters before development of PA-AVF. Diagnosis of HD catheter-related blood stream infection (HD-CRBSI), which overlapped with development of PA-AVF, was proven in 4 patients, two of which also had surgical site infection. One patient had traumatic PA-AVF and in two patients the cause could not be established although features consistent with CRBSI were present. Excision of pseudoaneurysm and ligation of radial artery was done in all cases.

Conclusion:

Infection is the most common cause of anastomotic pseudoaneurysm of AV fistula. Our study points towards extended use of non-cuffed hemodialysis catehters as a risk factor for development of PA-AVF. Prevention and early aggressive management of CRBSI and surgical site infections along with a limited use of non-cuffed HD catheters for the minimum required duration is the key to reduce the incidence of this complication

Objective:

To report the applicability of ambulatory cleft lip repair (CLR) and to review the existing literature.

Materials and Methods:

This is a retrospective clinical case series study of ambulatory CLR in North-western Nigeria. The study was carried out in Usmanu Danfodiyo University Teaching Hospital (UDUTH), Sokoto, between January 2012 and December 2018. Relevant clinical data of the subjects obtained include sociodemographics, type of cleft, and complications. Protocol employed includes premedication with diazepam (0.5 mg/kg, IV) slowly, followed by administration of glycopyrrolate (0.005 mg/kg, IV) and diclofenac potassium (1 mg/kg, IV). Then, ketamine (0.1 mg/kg, IV) was infused slowly over a 5-min period to achieve procedural sedation (Ramsey sedation score of 3). The data were analyzed using (SPSS; Chicago, IL, USA) program, version 20. The results were presented in simple descriptive statistics.

Results:

The age ranged from 2 to 21 years with male preponderance (M: F = 4:1). All participants had unilateral clefts lip with or without alveolus. The left side was twice involved as the right. There were no perioperative complications nor mortality recorded and no patient required conversion to general anesthesia. All patients were successfully discharged home on the same day of the operation. No case of readmission was recorded and subsequent follow-up was uneventful.

Conclusions:

Parenteral use of ketamine and diazepam for outpatient pediatric cleft lip procedures is safe and of immense benefits in reducing the surgical cleft burden without compromising patients safety.
