A mutual-aid group for Latino and Latina adolescent survivors of parental intimate partner violence
Authors: Molina Olga , Chapple Reshawna
Published: May 2023

This qualitative study explores the perceptions of Latino and Latina adolescent survivors of parental intimate partner violence (IPV) who participated in mutual-aid groups. Two focus groups were conducted. Data were analyzed utilizing a grounded theory approach. Five conceptual themes arose including: (a) feelings about the parental intimate partner violence; (b) reflections about group activities that helped them cope with the violence at home; (c) the role of the group in enabling a safe home away from home; (d) the impact of the Latino culture on adolescent survivors of parental IPV and (e) adolescent post-group experiences. Findings indicated that overall the group experience was overwhelmingly positive. It helped the adolescents decrease feelings of depression, isolation, improved self-esteem and was empowering. Implications for social workers include utilization of mutual aid groups with Latino/a adolescent survivors of parental IPV.Keywords: mutual-aid groups, domestic violence groups, Latino and Latina adolescents, survivors of parental intimate partner violence, undocumented immigrants, resilience theory; groupwork; group work
How Pre-deliberation Processes Predict Group Discussion: An Application of the Goals-Plans-Action Model
Authors: Henningsen Mary Lynn Miller , Henningsen David Dryden
Published: May 2023

The goal of the study was to investigate the role of pre-deliberation planning on the enactment of normative and informational influence attempts during group decision-making. The goals-plans-action model (Dillard, 1990) was used to frame the study. The participants (N=112) performed a judgmental group decision-making task. The results of the study support the GPA in several ways. Pre-deliberation plans were enacted in discussion. In support of the extant group literature, perceptions of the task type influenced the proportion of pre-deliberation informational plans. Post-discussion attitudes toward the group’s decision were related to goals and to the proportion of normative plans.
Dialogic sharing of lived experience in different self-help/mutual aid groups
Authors: Munn-Giddings Carol Diane , Borkman Thomasina
Published: May 2023

This article is based on a recent re-visiting of published data related to the ‘sharing’ processes between members of two strikingly different types of self-help/mutual aid groups (SHMAGs) run by and for peers who share the same situation.    Data from taped meetings and observations with a stress-coping Carers’ groups is compared with observational data from an identity changing Alcoholics Anonymous group and discussed in relation to Bohm’s (1987, 1996/2013) concept of dialogue as an alternative communication process that facilitates inquiry and the accumulation of knowledge. Groups were at extreme opposites in terms of their expected goals, strategies of help, and organisational characteristics yet unexpected similarities were found in relation to the authority of sharing lived experience which was in both cases respectful, supportive and non-judgemental. Group members did not openly disagree with each other but expressed a difference in opinion by the juxtaposing of a personal story which suggested an alternative way of doing or viewing things.    The paper contributes to our knowledge of how sharing lived experience can be a key similarity between strikingly different SHMAGs.  The paper also contributes to our understanding of the usefulness of dialogue as an explanatory framework for viewing SHMAGs as collective learning enterprises.Keywords (up to 6): self-help/mutual aid groups, lived experience, dialogue, collective learning, sharing stories
“A place where I am always welcome”: A thematic analysis of what belonging to Alcoholics Anonymous means to its members
Authors: Ogilvie Lisa , Prescott Julie , Carson Jerome
Published: May 2023

The purpose of this study is to explore what belonging to Alcoholics Anonymous (AA) means to its international membership. The aim is to gain a collective view of the opinions held by those accessing the services offered by AA globally. This paper focuses on the study of AA entirely from the perspective of its members, without being attentive to the AA approach to recovery, or the 12-step programme it advocates. An online survey was distributed as a link on Facebook groups accessed by members of AA. Responses (N=182) were received from members accessing AA services in 11 different countries. These were analysed using thematic analysis. The findings convey a positive message for what belonging to AA means, demonstrating that members accomplish more than sobriety and sustained abstinence. They develop a positive outlook, feel connected and accepted into a unique community, that offers a platform for achieving personal and spiritual growth.
Amaru: rede de conhecimento em terapia ocupacional da América Latina
Authors: Lopes Correia Ricardo , Silva Carla Regina , Bianchi Pamela Cristina , Monzeli Gustavo Artur , Takeiti Beatriz Akemi , Morrison Rodolfo , Testa Daniela
Published: May 2023

This paper presents the challenges of production and dissemination of knowledge in Occupational Therapy in Latin America, its place in the global scenario and the weaving of a political-epistemic network of communication, discussion and exchange. A sense of groupwork, processes and intervention as a collective network is proposed to analyse and understand the social relational practices that make up the political-epistemic network between key-subjects, different types of knowledge, as well as different ways of producing and disseminating them for the institutionality of the field of Occupational Therapy itself and for its outreach in society in general. To this end, we describe and analyse the actions of the Amaru Network as a collective strategy to face the challenges of the production and dissemination of hegemonic and excluding knowledge in Occupational Therapy in the Latin American context. We take as the axis of analysis the idea of collective as a conceptual category that serves to designate and guide the counter-hegemonic processes of knowledge production in the scientific and cosmological reality of the Latin American region. The Amaru Network, in proposing and sustaining a social practice engendered in a collaborative network between Latin American countries, turns its gaze to the broadening of epistemological bases for other possible modes of knowledge production.
Este ensaio apresenta os desafios da produção e difusão de conhecimento em Terapia Ocupacional na América Latina, seu lugar no cenário global e a tessitura de uma rede político-epistêmica de comunicação, de discussão e troca. Propõe-se um sentido de trabalho em grupo, de processos e intervenção, enquanto coletivo em rede para analisar e compreender as práticas sociais relacionais que conformam a rede político-epistêmica entre sujeitos-chaves, diferentes tipos de conhecimento, bem como distintos modos de produzi-los e difundi-los para a institucionalidade da própria área de Terapia Ocupacional e para seu alcance na sociedade em geral. Para tanto, são descritas e analisadas ações da Rede Amaru como estratégia coletiva no enfrentamento aos desafios da produção e difusão do conhecimento hegemônico e excludente em Terapia Ocupacional que se colocam ao contexto latino-americano. Tomamos como eixo de análise a ideia de coletivo enquanto uma categoria conceitual que serve para designar e orientar os processos contra-hegemônicos da produção de conhecimento na realidade científica e cosmológica da região latino-americana. A Rede Amaru, ao se propor e sustentar uma prática social engendrada em uma rede colaborativa entre países latino-americanos, volta seu olhar para o alargamento das bases epistemológicas para outros modos possíveis de produção de conhecimento

A arte na engenharia do século XIX: ornamento e estética arquitetônica nas obras de infra-estrutura urbana
Authors:   Pontifícia Universidade Católica de Campinas, Oliveira Carolina Bortolotti de
Published: May 2023

Em meados do século XIX na Europa, tanto o campo de atuação dos arquitetos como dos engenheiros passa por transformações. Enquanto o profissional de arquitetura se volta aos projetos residenciais, à decoração de interiores e às discussões a respeito de suas atribuições na intervenção das cidades – uma vez que o urbanismo se torna uma disciplina científica; os engenheiros enfrentavam os desafios alarmantes que tomavam conta das cidades industriais: falta de sistemas de abastecimento de água, tratamento de esgoto, iluminação, redes de transportes, pontes e viadutos, além das melhorias portuárias. Dentro desse cenário internacional, a revista britânica Engineering, lançada em 1866, procura estabelecer um debate com seu público leitor, tratando não apenas da formação técnica e prática – característica do ensino da engenharia, mas enfocando aspectos artísticos até então ausentes na formação de um engenheiro civil. Destaca-se aqui a inserção de ornamentos e elementos decorativos oriundos da linguagem arquitetônica, medidas e proporções que deveriam revelar a beleza do desenho nas construções monumentais, a questão do “gosto na engenharia”, que deveria passar pela apreciação pública, enfim, um novo olhar é lançado sobre os equipamentos urbanos que emergem, nesse momento, como autênticas “obras de arte”. O presente artigo, portanto, pretende verificar em que medida a representação das obras de engenharia tornaram-se um legado visual para compreensão das rápidas transformações ocorridas, sobretudo, na segunda metade do século XIX, uma vez que a revista Engineering traz inúmeros projetos, desenhos, detalhes construtivos e ornamentais, reproduzidos diariamente junto às reportagens. Pretende-se analisar também em que medida o repertório arquitetônico foi amplamente incorporado aos projetos de engenharia.
Do pictoral ao moderno sem fronteiras práticas: fotográficas de vanguarda a serviço da fotografia amadora
Authors:   Universidade Federal de Minas Gerais, Menezes Lucas Mendes
Published: May 2023

Esta comunicação tem como objetivo analisar o fenômeno da apropriação de práticas fotográficas artísticas consideradas de vanguarda na produção de fotógrafos artistas amadores entre os anos de 1940 e 1960. Apesar do impulso inicial deste breve trabalho se relacionar com a pesquisa em desenvolvimento no mestrado – que tem como foco a realidade fotográfica artística belo-horizontina – nosso ponto de partida não diz respeito a uma localidade específica; construiremos uma abordagem temática a partir do contato com publicações especializadas (nacionais e estrangeiras), catálogos de exposições organizadas por foto-clubes de várias localidades do mundo, assim como imagens fotográficas oriundas de diferentes coleções. O material analisado foi catalogado através de uma pesquisa realizada nos seguintes acervos: da Société Française de Photographie e da Maison Européenne de la Photo, ambas localizadas em Paris e com uma riquíssima coleção de publicações com o tema da fotografia de várias localidades do mundo; do fotógrafo belo-horizontino Wilson Baptista, fundador do Foto Clube de Minas Gerais (FCMG) em 1951, cuja coleção é constituída por catálogos de exposições e publicações nacionais e internacionais de fotografia; e também alguns números da revista Fotoarte, criada por iniciativa de fotógrafos amadores brasileiros membros de foto-clubes e publicada a partir de 1958. Desta forma, a produção dos fotógrafos amadores não será abordada em sua totalidade; optamos por analisar imagens e textos de fotógrafos formalmente reunidos nessas associações de aficionados no período mencionado.
Fin-de-siècle: luxúria, morte e prazer
Authors:   Universidade Estadual de Campinas, Costa Junior Martinho Alves da
Published: May 2023

Este artigo gravita sobre uma questão latente do final do século XIX: a articulação entre Luxúria, morte e prazer. Certamente esta questão não nasce no bojo daquilo que hoje, grosso modo, chamamos de Decadentismo e Simbolismo, contudo neste período, irrefutavelmente, ganha nova roupagem e dita novas diretrizes para as artes. Este tema já é revigorado com o Romantismo, a “beleza meduséia” torna-se uma chave importante para a compreensão deste período. O termo, emprestado de Mario Praz, faz menção exatamente ao belo no que tange seus aspectos que parecem contrariá-lo.
Fronteira e diálogo na arte japonesa
Authors:   Pontifícia Universidade Católica de São Paulo, Okano Michiko
Published: May 2023

Este texto faz um recorte da história da arte nipônica, precisamente do período no qual se estabelece um intenso diálogo entre o Japão e o Ocidente, na segunda metade do século XIX. Trata-se de uma época em que um intercâmbio se efetivou em dupla direção - o Japão acatou o Ocidente como modelo e a Europa descobriu e encantou-se com a arte japonesa, especificamente, com a xilogravura Ukiyo-e. A adoção desse modelo ocidental pelo Japão acarretou, ao mesmo tempo, a exclusão de áreas que passaram a ser consideradas periféricas, tais como as artes tradicionais japonesas, que não se encaixavam nos novos moldes, e a criação de movimentos artísticos que se contrapunham às representações da arte provenientes da Europa. Tal processo de ocidentalização gerou também ambiguidade dos termos empregados para se referir à arte e gerou uma tênue fronteira entre a arte e o artesanato ou as artes tradicionais do dô.

Language in Mathematics Education: On the epistemic and reconstructivistic side of languaging processes
Authors: Kuzu Taha Ertuğrul
Published: May 2023

[English]: In this article, languaging processes in mathematics education will be reflected from a theoretical and methodological viewpoint. Language is not just a tool for language learning: It is a highly complex medium for transporting meaning. It plays a key role in explaining and fostering as well as reconstructing and interpreting cognitive processes – not only in mathematics education, but due to the abstract nature of mathematical objects in a particularly important way. Thus, language as a mediational dimension is essential in the learners’ as well as researchers’ processes of understanding, be it in interpretational processes or in verbalized, deictical, either explicit or implicit explanations and actions. In this article, this dual-sided perspective will be explained by giving insights into language-related processes of interpreting and understanding mathematical relations in Substantial Learning Environments (SLE’s) as well as relational strategies such as the ‘Auxiliary Task.’
[Bahasa]: Artikel ini membahas proses berbahasa dalam pendidikan matematika dari perspektif teoritis dan metodologi. Bahasa bukan saja sebuah alat untuk pembelajaran bahasa tetapi juga sebuah medium yang sangat kompleks untuk menyampaikan makna. Bahasa memainkan peran penting untuk menjelaskan dan memelihara serta mengembangkan dan memaknai proses kognitif - tidak hanya dalam pendidikan matematika, tetapi karena karakateristik objek matematika yang abstrak sehingga peran bahasa diperlukan. Oleh sebab itu, bahasa sebagai sebuah dimensi mediasional sangat penting dalam proses pemahaman siswa dan peneliti baik itu dalam proses interpretasi atau dalam penjelasan dan tindakan yang diverbalkan, deiktis, baik eksplisit maupun implisit. Dalam artikel ini, perspektif dua sisi ini akan dijelaskan dengan memberikan wawasan ke dalam proses yang berhubungan dengan bahasa untuk menafsirkan dan memahami hubungan matematika dalam konteks Linkungan Belajar Substansial (Substantial Learning Environments, SLE) serta strategi relasional seperti Tugas Tambahan (Auxiliary Task).

Health Risk Assessment Via the Consumption of Clam (Corbicula largillierti) Accumulated Heavy Metals (Pb) and Coliform Bacteria at Kapuas River, West Borneo
Authors: Rahayu Widya , Sari Dahlia Wulan
Published: May 2023

As population activity is increasing and the Kapuas river is still a means of transportation, causing Corbicula largillierti to accumulate heavy metals (Pb) and Coliform bacteria in their bodies. This makes it dangerous to be consumed by humans. Thus, this research has two main aims. First, to find out the concentration of Pb and Coliform inside Corbicula largillierti that lives at Kapuas river, Pontianak and the river’s water. Second, to analyze the health risk of consuming the clams. Furthermore, the Atomic Absorption Spectrophotometer (AAS) is used to analyze the Pb sample and the Most Probable Number (MPN) method is used to analyze the Coliform. The result of this research shows that concentration Pb and Coliform from the Kapuas river have exceeded the limits designated for aquatic biota based on the Decree of the State Minister for the Environment No. 51 of 2004. In addition, the health risk is measured using Estimated Daily Intake (EDI), Target Hazard Quotient (THQ) and Target Carcinogenic Risk (TR) with scores for each are >10 times the RfD, >1 and 10−3. This result shows that based on the clam Corbicula largillierti consumption for 70 years life span of 60 kg body weight,  had a high and negative effect on health risk problems and had a cancer risk for consumers. However, the health risk problem might increase much worse due to the long and continual period of consumption exceeding estimated daily intake.

Published: May 2023

The purpose of this study was to evaluate the suitability of water quality parameters in intensive white shrimp (Litopenaeus vannamei) cultivation activities based on Good Aquaculture Practice (GAP) quality standards implication practice. This research was carried out with the ex-pose facto causal design concept during one cycle of shrimp cultivation, with the indicator being studied was the condition of the water quality parameters which were then corrected with the GAP standard according to the Minister of Agriculture Regulation No. 75 of 2016. The results showed that the condition of the water quality parameters during the cultivation period was still in accordance with the GAP quality standards, except for the alkalinity parameter which had a value of 157 mg/L and organic matter 104.43 mg/L, both values ​​were above the GAP quality standard threshold. The abnormal condition of the two parameters was caused by unpredictable natural and seasonal factors. This can be seen from the trend of the temperature and salinity parameter graphs that fluctuate unstable. Furthermore, for technical parameters, the cultivation system at the research site was still in accordance with the cultivation quality standards listed in the GAP. Based on the discussions, it can be concluded that the water quality parameters at the research pond location as a whole were still in accordance with the GAP quality standard which refers to the Minister of Fisheries Regulation No. 75 of 2016, except for the alkalinity and organic matter parameters which had a slightly worse concentration than the GAP quality standard.

Published: May 2023

Shrimp farmers have reported mass mortality of white shrimp (Litopenaeus vannamei), reaching 2-3 kg/day in Gerongan Village, Kraton District, Pasuruan Regency in mid-2021. Preliminary analysis suggests that mass mortality was caused by bacterial diseases. Thus, to find out the main pathogen causing the mass mortality, the present study investigated microbial composition in rearing media of white shrimp (Litopenaeus vannamei) infected by the white feces disease (WFD) and healthy white shrimp using next-generation sequencing (NGS) technology. The research was conducted by collecting normal water samples and infected shrimp pond water samples. The results of the NGS assay showed that Vibrio vulnificus was found dominant in WFD-infected shrimp pond water, therefore was suspected to be the main cause of WFD.
Aquafeed Biofloatation through Mycelial Hydrophobic Coating

Published: May 2023

Aquafeed biofloatation through tempeh mould fermentation on sinking aquafeeds produces water-floating property, an alternative to the expensive extrusion technique. However, the role of the fungal mycelium in this biofloatation remains unclear.  This study aimed to investigate the role of surface mycelium of the fermented feed in the buoyancy. Commercial sinking feed was fermented using a tempeh starter at ambient temperature (28–33 °C) for 48 h. Freshly fermented feeds were produced, some of which were peeled to remove the surface mycelium, while the others were left intact. After 24-h oven-drying at 50 °C, physical tests were done on the peeled and unpeeled fermented feeds, plus unfermented feed as a negative control. Results showed that the unpeeled fermented feed had the highest floatability (48% at the 60th minute), and continued floating until the 120th minute with 36% floatability. In contrast, the unfermented feed did not float at all, while the peeled fermented feed sank within the first 2 minutes. Only the unpeeled fermented feed showed hydrophobic characteristics (> 90° contact angle and 20.16 s water absorption time). Thus, the hydrophobic surface mycelium might prevent rapid water infiltration into the fermented feed matrix, enabling the intact fermented feed to float longer.
Strong metal-support interaction of Pt-based electrocatalysts with transition metal oxides/nitrides/carbides for oxygen reduction reaction
Authors: Chen Min
Published: May 2023

The practical application of carbon-supported Pt-based catalysts for the oxygen reduction reaction (ORR) in proton exchange membrane fuel cells (PEMFCs) still faces many limitations, including carbon corrosion and their weak interaction with Pt-based nanoparticles (NPs). Harnessing the strong metal-support interaction (SMSI) effects at the interface between Pt-based nanoparticles and alternative corrosion-resistant non-carbon support is an effective strategy to address these issues. The rational design of Pt-based catalysts with favorable SMSI and elucidation of the mechanisms underlying such interactions is indispensable for achieving desirable activity and stability. In this review, first, the basic principles of the ORR are briefly introduced. Next, the formation process of SMSI, construction strategies, and the advantages and drawbacks of representative supports, including transition metal oxides, nitrides, and carbides (TMOs, TMCs, and TMNs, respectively), are fully discussed. Finally, the challenges and prospects in promoting the practical applications of the SMSI effect for ORR are highlighted.

Rootstock election is one of the key decisions when designing a vineyard. Although the research performed to determine the effect they induce in the behaviour of scion varieties is not scarce, it is not easy to have a global idea, as results are usually published scattered. In this work, we re-examine previous research conducted in Spain on rootstock implications on vine agronomic performance through the performance of a meta-analysis (MA). As a result, we were able to integrate the information reported in 20 articles that included rootstock experimentation conducted with 36 different varieties and 47 different rootstocks, totalling 764 individual records. However, when the information was filtered before the meta-analysis, this number decreased to 312 records, for which rootstock Response Ratios (RR) were calculated.
The characteristics conferred by the rootstock were more closely related to the rootstock itself, rather than to the characteristics of the Vitis sp. crossing used to create the rootstock. Several rootstocks were identified as more suitable for adapting to future climate change conditions, as far as they were able to moderate sugar accumulation and pH (161-49 C, 41-B MGt and 420A MGt). Meanwhile, 140 Ru and 5-BB were observed to provide high pH and sugar contents despite their high yield. In conclusion, despite being based on data from a single country, the meta-analysis was shown to be a useful tool for enhancing the value of previous research on rootstocks. Combining articles from both peer-reviewed and technical journals helped in the assessment of the implications of different rootstocks, although further steps should be taken to facilitate data integration (harmonisation of measurement and reporting procedures, open data repositories, etc).
Pencantuman Label Alergen dalam Pelabelan Produk Pangan Sebagai Bentuk Perlindungan Konsumen
Authors: Muhammad Danang Wahyu , Kautsar Izzy Al , Latifah Emmy
Published: May 2023

The purpose of this study is to present a normative analysis of the labeling of food products in Indonesia and the relationship between information disclosure on food labels and the implementation of consumer protection. This research uses normative juridical methods. The results conclude that first, the current global food issue is the danger of consuming food ingredients that contain allergens. The United States, Singapore and Japan have required the inclusion of allergen information in the labeling of food products in their respective National Laws. This is a lesson for Indonesia to require the inclusion of allergen information in the National Law. Therefore, a limited revision of Article 97 paragraph 3 of the Food Law is needed to include the obligation to include warnings for allergen content on food labels. Second, many food products do not display information in accordance with reality and its original content, which is detrimental to consumers. Consumer protection in food regulation through food labeling departs from the State's efforts to safeguard the rights and interests of these consumers so that they are not harmed by profit-oriented producers by way of processing and distributing fair and healthy food products based on the principle of information disclosure.

A Time Two-mesh Finite Difference Numerical Scheme for the Symmetric Regularized Long Wave Equation
Authors: Gao Jingying , He Siriguleng , Bai Qingmei , Liu Jie
Published: May 2023

This paper proposed a time two-mesh (TT-M) finite difference numerical scheme to improve the efficiency of solving the symmetric regularized long wave (SRLW) equation. The TT-M Crank-Nicolson discretization and finite difference method are employed in time and space approximation respectively. The scheme involves three main steps: firstly, the time interval is divided into coarse and fine time meshes, then the nonlinear system is solved on the coarse time mesh; secondly, coarse numerical solutions on the fine time mesh are computed using an interpolation formula based on the solutions derived in the step one; lastly, the TT-M finite difference numerical solutions can be obtained through constructing the linearized fine time mesh system using Taylor’s formula. Compared to the currently existing TT-M numerical methods, the novelty of this study is that the nonlinear term including derivatives is linearized by Taylor’s formula for a function with three variables, whose error analysis is more complex. Finally, some numerical examples, including computational time and accuracy, preservation of conservation laws, are given to verify the efficiency of the scheme. By comparing it with the standard nonlinear finite difference scheme, this method can reduce CPU time without sacrificing accuracy.
Evaluating the Impact of Engineering Works in Tidal Flats Using Time-Series Satellite Images – Case of the Mont-Saint-Michel Bay, France
Authors: Deroin Jean-Paul
Published: May 2023

The Mont-Saint-Michel is known worldwide for its unique combination of the natural site and the Medieval abbey at the top of the rocky islet. But the Mont is also located within an estuarine complex, which is considerably silting up. For two decades, large-scale works were planned to prevent the Mont from being surrounded by the expanding salt meadows. The construction of a new dam over the Couesnon River, the digging of two new channels, and the destruction of the causeway were the main operations carried out between 2007 and 2015. The remote sensing approach is fully suitable for evaluating the real impact of the engineering project in both time and space, particularly the expected large-scale hydrosedimentary effects, for reestablishing the maritime landscape around the Mont. Sentinel-2 satellite data have been used for the period from 2015 to 2023. Aster data were used for the previous period covering 2000 to 2017. Aerial photographs and an ALOS scene have been also used. The remote sensing approach is based on time-series images. It allows identifying local or regional consequences and temporary or permanent effects. The migration of the different channels (especially for the new west and east Couesnon river courses) and the erosion-progradation balance of the vegetation through space and time are the main features to study. Between 2007 and 2023, the erosion of the salt meadows is significant to the south-west of the Mont (− 150 ha) but more limited to the south-east (− 65 ha). The erosion effect is limited to the immediate environment because the vegetation fringe of the uppermost tidal flat along the main dike is slightly increasing (+ 35 ha) to the west and to the east (+ 40 ha). During the same period, the sedimentation considerably increased to the north-east of the Bay, between the Bec d’Andaine, the Grouin du Sud and Tombelaine islet, which seems now facing the same silting-up problem. At this stage, the remote-sensing survey indicates mixed results for the engineering project.
Impact of Converting On-Street Parking Lots to Bus-Only Lanes on Traffic Efficiency and Emissions in the Age of Autonomous Vehicles
Authors: Zhou Ling , Ye Xiaofei
Published: May 2023

Autonomous vehicles (AVs) may not only reduce parking demand, but also free up on-street parking spaces. From the perspective of bus priority, converting on-street parking lots into dedicated bus lanes can both ensure bus priority and accommodate non-bus traffic, helping to reduce congestion and pollution. In order to study the impact of conversion of on-street parking lots to bus lanes on traffic flow, a microscopic simulation framework based on VISSIM is proposed in this paper. Data was collected using the floating car method and video recording method to quantify the factors affecting traffic flow due to the conversion of on-street parking. The VISSIM simulation model was then calibrated. According to the proportion of the on-street parking lots into a bus lane, the on-street parking lots conversion simulation model of different scenarios was established, and the influence of different on-street parking lots conversion ratio on traffic efficiency and pollution emission was quantitatively analyzed. Finally, the optimization method based on bus lane network connectivity is discussed. The results indicate that: When the on-street parking lots conversion ratio is approximately 100%, bus speed increases by 21.03%, bus delays decrease by 14.27%, and bus parking instances decrease by 11.31%. Total emissions are negatively correlated with vehicle speed. As the conversion rate of on-street parking increases, the emissions of road segments and the entire road network gradually decrease. At a conversion ratio of 100%, the average total emissions for road segments have the highest reduction rate, decreasing by 4.12%. At a conversion ratio of 50%, the average emission total for the road network shows the largest reduction, falling by 2.88%.

Published: May 2023

The effects of 1%~5% cold compression on the mechanical properties, microstructure and residual stress of 7050 aluminum alloy were investigated, and the results were applied to the complex die forging with stiffener structure. The results show that with the increase of cold compression, the tensile strength of forging decreases gradually, but the conductivity and fracture toughness of the forging have little change. TEM microstructure shows that with larger cold compression (5%), the dislocation density was relatively higher, which promoted the precipitation and growth of precipitated phases at positions with higher dislocation density during aging process. The ultrasonic tests of residual stress show that with the increase of cold compression, the residual stress in the forging decreases first, and then increases when cold compression reaches 5%. The results of the die forging of 7050 aluminum alloy with bar structure show that the residual stress of the die forging is obviously eliminated after 2-4% cold compression, and the deformation after machining is obviously less than of the uncompressed forgings. The combination of bar and web is more beneficial to the uniform distribution of residual stress of the die forging with bar structure.
Use of Rotavirus Vaccine as a Containment Measure for SARS- CoV-2 Coronavirus (COVID-19): A Study of Possible Cross and Trained Immunity
Authors: Lorite - Ayan Nuria
Published: May 2023

This proposal was prepared in the very first weeks of 2020 because of the outbreak of COVID-19. There are good reasons to suppose that rotavirus vaccine can be used as protection tool to effectively and safely fight and mitigate SARS-CoV-2 infection and the impact caused by COVID- 19 in adult humans, due to the development of cross and trained immunity following rotavirus vaccination. Up-to-date, some rotavirus vaccines are available and approved, two of them have a large experience in results and safety. Little experience has been achieved in the use of rotavirus vaccine in adults. However, it can be expected that it would be safe and effective in adults and in the elderly as well. This proposal explains the background of this hypothesis based on lungs and intestine relationships.

Pulsed electric fields of specific frequencies emitted by a glass plasma antenna tube have been shown to slow the growth of Acute Lymphoblastic Leukemia cells by as much as 43% when exposed to a series of frequencies between 156kHz and 162kHz. This narrow band of frequencies is termed a “Destructive Cancer Resonant Frequency Formant” (DCRFF).

The development of magnesium calcium phosphate bone cements (MCPCs) have garnered big attention. MCPCs are bioactive and biodegradable and have appropriate mechanical and antimicrobial properties for use in reconstructive surgery. In this study, the cement powders based on a (Ca + Mg)/P = 2 system doped with Zn2+ at 0.5 and 1.0 wt.% were obtained and investigated. After the mixing with a cement liquid, structural and phase composition, morphology, chemical structure, setting time, compressive strength, degradation behavior, solubility, antibacterial activities, and in vitro behaviour of the cement materials were examined. A high compressive strength of 48 ± 5 MPa (mean ± SD) was achieved for the cement made from Zn2+ 1.0-wt.%-substituted powders. The Zn2+ introduction led to antibacterial activity against Staphylococcus aureus and Escherichia coli strains, with an inhibition zone diameter up to 8 mm. Biological assays confirmed that the developed cements are cytocompatible and promising as a potential bone substitute in reconstructive surgery.
Metallic and Insulating Phases in Two-Dimensional Strongly-Coupled Field Theories With a Gravitational Dua
Authors: Stephenson Matthew
Published: May 2023

We consider a specific holographic model in the limit where the gauge field does not couple to the rest of of the holographic fields (gravity and scalar sector) and investigate a phase of matter at zero charge density, a realistic feature that may have implications for disordered strange metals. We then pick a specific form of the gauge coupling $Z(\alpha)$ with a certain disorder realization and argue that this provides a hard-gapped insulator with exponentially-suppressed conductivity by holographic methods. The limit is non-trivial: as there is backreaction at zero density amount, surviving in the coupled case.
Carbon-Intensity and Carbon-Efficiency of Charcoal Production, by Pathway
Authors: Johnson Eric P
Published: May 2023

There are four commercial pathways to make grill charcoal from wood. These have been modelled to calculate a carbon intensity (CI) for each. Results are presented along with discussion of the sensitivities: biogenic carbon; quality of the charcoal; classification of products, wastes and residues; and division of burden. Grill charcoal’s CI ranges greatly, depending on the pathway by which it is produced. Wood distillation, a commercial process that once was common but now is rare, has a CI 50+% lower than that of the next-lowest commercial process, Kilns. Earth mounds/pits and external-fuelled Retorts have CIs considerably higher still. The carbon efficiency (CE) of Wood distillation is more than twice that of the next-best, again Kilns. CE is defined as normalised, total carbon emitted. This is not the same as CI, it is not usually considered in studies such as this, yet it is important for climate impact. CE could be a useful measure in assessments (such as this) where biogenic carbon is significant.

Stress is one of the important factors affecting the growth and development of plants. In recent years, a large body of data on transcriptional changes in response to stress in plants has been obtained. Despite the fact that the important role of the regulation of translation in response to stress has been proven in plants, knowledge in this area remains extremely scarce. In this review, we focused on mRNA translation in the cytoplasm of higher plants. Most of the current research on the effects of translation has been done in yeast and mammalian systems. Translation factors and mechanisms are mostly conserved among eukaryotes; however, some differences are known to exist among plants. A comprehensive understanding of the complex apparatus of translation and its regulation in plants is required. In this work, we have tried to update modern ideas about the regulation of translation under conditions of abiotic stress.
