Disability: Between Mobility and Organizational Inclusion
Authors: Fattori Lorenzo
Published: April 2022

Various charters of rights in Western society recognise a specific right to mobility, but it may actually be difficult to travel freely for some citizens. Indeed, people with disabilities often encounter technical or organisational problems that prevent them from enjoying this right. We believe that ensuring mobility is fundamental for the organisational inclusion of people with disabilities. Since the early 1990s, many legislative provisions have been drafted to create and improve travel possibilities for people with disabilities in Italy. Therefore, after thirty years, it is legitimate to investigate the state of the arts of such provisions nowadays. Thus, the following paper carries out a specific study of the functioning of transport systems from the point of view of people with disabilities so as to explore the possibilities of improvements. Furthermore, this study evaluates if further interventions are necessary regarding the legislative framework and, above all, the actual possibilities of mobility offered by transport systems, beginning with the railroad, which first, in the 1980s, started to offer specific services for people with disabilities.
Sexual Fluidity and Attitudes towards Bisexuality
Authors: Sbrana Serena , de Miguel Adelia
Published: April 2022

The following research provides an instrument to assess sexual fluidity changes over time in attractions and sexual orientation identity, thus examining whether experiencing sexual fluidity is related to specific cognitions, attitudes and beliefs among sexually and non-sexually fluid individuals. Participants (435 Spanish young adult students, 310 females and 125 males) completed an online form assessing demographic data, sexual orientation, sexual fluidity, and attitudes towards male and female bisexuality. An empirical sexual fluidity factor has been isolated: women scored higher than men (d = .68), and bisexual people higher than the homosexual (d = 1.74) and heterosexual (d = 1.40) groups. The study also highlights gender, sexual orientation and sexual fluidity differences in attitudes towards male and female bisexuality. Indeed, women consider male and female bisexuality more stable than men (d = .29 & d = .34); sexually fluid people show higher positive attitudes towards male and female bisexuality (d ranged .29 – .51) than the non-sexually fluid group; bisexual individuals scored higher in male and female bisexuality attitudes than heterosexual individuals. This study confirms previous research that showed that female individuals are more likely than male to have fluid sexuality. Attitudes about bisexuality are not a simple question: they are affected by gender, sexual orientation and sexual fluidity factors.

Authors: Cabral Caíque Lima , Castro João Wagner Alencar
Published: April 2022

Ciclones são agentes meteorológicos-oceanográficos, responsáveis por mudanças rápidas nos padrões de erosão e deposição de sedimentos nas zonas costeiras. O setor oeste do Oceano Atlântico Sul, próximo à costa leste da América do Sul é favorável à gênese de ciclones extratropicais. No litoral do Estado do Rio de Janeiro, a passagem de ciclones, ocorre de forma episódica, acarretando inundações costeiras e impactos ambientais sobre a infraestrutura urbana local. O presente artigo, objetiva investigar o registro sedimentar ciclogênico em camadas de lamas orgânicas superficiais de pântanos costeiros desse segmento de litoral brasileiro. Procedimentos metodológicos incluem análises de dados multi-proxies, envolvendo, testemunhagem, padrões granulométricos, perfis faciológicos, tratamento palinológico, interpretação de lâminas delgadas de palinomorfos, complementadas por técnicas geocronológicas de percentual de carbono moderno - pMC e isótopos estáveis de carbono. Resultados obtidos em testemunhos posicionados a 0,5 m acima do nível médio do mar, à 1,0 km da linha de praia, sugerem inundação marinha de grande proporção no início do século XX na área ocupada pela Marina Porto Búzios, Armação dos Búzios - Rio de Janeiro.
Evidências de captura fluvial no semiárido setentrional brasileiro: o caso do divisor entre os rios Acaraú e Aracatiaçu
Authors: Rodrigues Wesley Feitosa , Salgado André Augusto Rodrigues , Maia Rúbson Pinheiro
Published: April 2022

Rearranjos de drenagem têm sido investigados e descritos em boa parte do território brasileiro desde meados dos anos 1960. A grande exceção é a região semiárida, principalmente o Nordeste Setentrional, onde as interpretações vigentes entendem que as bacias hidrográficas da região se organizam graças à antecedência e/ou superimposição. Entretanto, até essa região apresenta anomalias fluviais que tipificam processos de rearranjos de drenagem. Algumas dessas anomalias se localizam no divisor hidrográfico entre as bacias dos rios Acaraú e Aracatiaçu no semiárido cearense. Essas anomalias foram investigadas por meio de sensoriamento remoto, de geoprocessamento e de análise em campo de evidências geomorfológicas. Os resultados obtidos indicam que parte de um paleo alto curso da bacia hidrográfica do rio Aracatiaçu foi pirateada para a do rio Acaraú. Esse processo transferiu alguns milhares de km² de área entre as bacias hidrográficas e reorganizou toda a rede de drenagem da região investigada. A identificação dessa grande captura fluvial sugere que processos de pirataria fluvial podem ter papel ativo na modelagem do relevo e na organização das bacias hidrográficas do semiárido brasileiro, demonstrando a importância do tema para os modelos de evolução geomorfológicos propostos para a região.
Bases teóricas do modelo stream-power de incisão fluvial
Authors: Peifer Daniel , Cremon Édipo Henrique , Val Pedro , Fernandes Nelson Ferreira
Published: April 2022

A ausência de literatura nacional explicativa sobre o principal modelo matemático que descreve a erosão fluvial emescalas de tempo geológico (>103 anos), o modelo stream-power, é um fator limitante na formação de jovens geomorfólogos em consonância com o cenário internacional da disciplina. Isto dificulta o desenvolvimento de pesquisa geomórfica no Brasil que tenha inserção internacional. Esta nota técnica preenche esta importante lacuna da geomorfologia quantitativa brasileira com o primeiro trabalho em língua portuguesa que apresenta a derivação e as implicações do modelo stream-power. É nítida a tendência recente de trabalhos nacionais que empregam algoritmos sofisticados, relacionados com o modelo stream-power, para extrair informações quantitativas de modelos digitais de elevação. Ainda assim, o entendimento sobre a teoria física e matemática que embasa essas métricas topográficas é, no melhor dos casos, incipiente. Aqui, apresentamos a derivação do modelo stream-power usando duas abordagens, a primeira partindo da tensão de cisalhamento média e a segunda da taxa de perda de energia potencial por unidade de área do leito. Descrevemos a mecânica simplificada de diferentes processos deerosão fluvial visando esclarecer uma noção genérica de “incisão fluvial” como resultado de um processo único, e, por fim, listamos as principais limitações do modelo.

Published: April 2022

Colorectal endoscopic submucosal dissection (ESD) is now widely performed and firmly established in the treatment of early-stage colorectal cancer. In particular, there have been many studies on difficult cases of colorectal ESD. Difficult cases can be divided into two groups: difficult dissection of the lesions and difficult approach to the lesion. In most cases, a combination of strategies can solve the problem. Challenging lesions such as those in the anal canal and ileum can also be treated from an anatomical perspective. In the rectum, there are no limits to size or circumference. In addition, the indications for ESD in patients without risk of metastasis other than deep invasion are being considered. Therefore, when ESD is performed on difficult lesions, it is necessary to ensure the quality of dissection.
A Novel Experimental Setup, Modelling and Static Behaviour of Cable-Supported Pipe Systems
Authors: Agwoko Marvin Paul , Zhi Hua Chen , Hong Bo Liu
Published: April 2022

Large spatial requirements in both onshore and offshore necessitate the investigation of the structural suitability of Cable-supported pipe system (CSPS) for transmission of fluids. This paper presents a novel experimental setup and finite element modelling of the CSPS structure. The
experimental setup involves the loading of the structure using pipe clamp loading pad. Scale down models, six scenarios accounting for the effect of mid span depth-span, number of truss modules, member sections, and single and double tubes pipe sections are presented subject to cable tension,
elastic and ultimate loading of the structure. The load– displacement responses of the six scenarios shows elastic responses and within limit stress until joint failure at ultimate load. Thus, the structure possesses the strength that can support its service life until loaded to the
ultimate limit of the joints. The failure mode of the structure suggested the need for the cable-truss joints to be design against sudden failure. Parametric evaluation based on member section properties reveals significant deformation when the cable section is reduced compared to other member
sections. The limit displacement of 64.8m span length (L) in comparison to other cable-supported structures is within L/600 - L/250, subject to check in different scenarios.

Die Geburt christlicher Porträts in antiken und modernen theologischen Kontroversen
Authors: POLAŃSKI Tomasz
Published: April 2022

Los pintores iconoclastas siempre han mantenido que su arte desciende a través de generaciones de Lucas y San Nicodemo. Las fuentes literarias griegas, siriacas, coptas y latinas ofrecen una selección de pasajes que hacen referencia a los iconos. Provienen principalmente del Concilio de Nicea (787). Los estudios de Elliger (1930) y Koch (1917) han marcado la discusión sobre los iconos a lo largo de los últimos cien años. Al mismo tiempo, la gran acumulación de restos arqueológicos ha ido mostrando que aquellos individuos con una visión anicónica, como Clemente de Alejandría o Tertuliano, representaban un círculo reducido de teólogos. La Carta a Constancia de Eusebio no surgió entre sus escritos hasta el s. VIII (787). Las huellas de los cuatro escritos de Epifanio de Salamina que son críticos con las imágenes también surgieron durante el periodo iconoclasta (G. Ostrogorsky). Y como si fuera contrario a todas las discusiones sobre imágenes de Cristo relacionadas con el cristianismo primitivo, el acheiropoietoi mostró a los cristianos el “verdadero rostro” de Jesús, revelado de manera milagrosa por el propio Cristo. Las fuentes literarias hacen referencia a dos tradiciones diferente sobre el acheiropoietos de Edesa (Acta Thaddaei, Doctrina Addaei), que ha sido documentado con el himno siriaco de la iglesia catedral de Urfa (c.550). La popularidad de las imágenes en los siglos IV-VII no podría pensarse sin una larga y previa trayectoria histórica.

El encomio del protomártir Esteban de Gregorio de Nisa entre hagiografía y βασιλικὸς λόγος
Authors: CHIRIATTI MATTIA COSIMO
Published: April 2022

La tradición hagiográfica transmitida e impulsada a partir del texto de los Hechos de los Apóstoles sobre el primer héroe del cristianismo primitivo, el protomártir Esteban, encuentra, en uno de los dos βασιλικοὶ λόγοι de Gregorio de Nisa (Gr. Nyss., Steph. I, ed. O Lendle, 1990, 97,4 - 105,21), una de sus más brillantes representaciones literarias. La hagiografía del santo se desarrolla siguiendo las normas del discurso imperial, teorizado en los dos tratados “Sobre los géneros epidícticos” atribuidos a Menandro el Rétor, en los cuales se hace hincapié en los τόποι ἐγκωμιαστικοί respecto al panegírico del personaje alabado. En la primera traducción al castellano, que presentamos a continuación, se pone un particular énfasis en esta innovación: el obispo de Nisa consigue transformar el relato neotestamentario en un discurso de fuertes matices propagandísticos, en el cual los aspectos más corrientes del personaje (patria, educación, actos) se convierten en virtudes y gestas de un arquetipo cristiano a seguir.

Farmer satisfaction level indicates the good opportunity to survive in the market by taking into account quality.
Temperature Transient Analysis of Naturally Fractured Geothermal Reservoirs
Authors: Wei Cao , Liu Yang , Deng Ya , Cheng Shiqing , Hassanzadeh Hassan
Published: April 2022

A potential approach to develop geothermal energy is by producing low-to-medium temperature fluids from naturally fractured geothermal reservoirs (NFGRs). Pressure transient analysis (PTA) is the most common approach to characterize such reservoirs for improving development efficiency. However, pressure inversion leads to nonuniqueness and cannot be used to estimate thermal properties. Moreover, reliable methods to evaluate the development potential of fractured geothermal reservoirs are lacking. To address the gap, this work aims to study the temperature behavior and explore a suitable analysis method for characterizing geothermal reservoirs and evaluating development potential.

We developed numerical and analytical models to analyze the temperature behavior in NFGRs. The developed models account for the Joule-Thomson [J-T effect (μJT)], adiabatic heat expansion/compression effect (ζ), reservoir formation damage, heat conduction, and convection effects. The developed numerical solution is verified and found to agree with the proposed analytical solutions.

The results show that temperature transient analysis (TTA) with constant or temperature-dependent μJT and ζ assumption leads to a minor difference when reservoir temperature changes significantly. Moreover, three heat radial flow regimes (HRFR) and a thermal interporosity regime with a V-shape characteristic have been identified. The results also show that temperature data provide information not accessible by PTA. The results reveal that temperature derivative curves signify a “hump” when formation around a wellbore is damaged, and the temperature data can be used to characterize the skin-zone radius and permeability. It is demonstrated that the properties such as J-T coefficient, effective adiabatic heat expansion coefficient, and fracture intrinsic porosity can be estimated using TTA. The results indicate that fracture thermal storativity (ωT) and matrix thermal interporosity coefficient (αT) can be estimated from the thermal interporosity regime exhibited on the temperature derivative curve. The results also suggest that commercial geothermal energy harness is more difficult when the ωT is high or the αT is very small. Finally, we introduced an integrated workflow of combining PTA and TTA to characterize NFGRs. Simulated test examples are interpreted to demonstrate the applicability of the developed workflow. This work aids in better understanding the potentials of temperature data on geothermal reservoir characterization.

Approximately 30–40% of growth hormone-secreting pituitary adenoma (GHPA) harbor somatic mutations in the GNAS (α subunit of the stimulatory G protein) gene. However, the latent functional role of the mutations and relative molecular mechanism in GHPA remain unknown. The GNAS gene mutations were detected in GHPAs using a standard PCR-sequencing procedure. The mutation-associated MEG3 expression was measured by RT-qPCR. MEG3 was manipulated in GH3 cells using a lentiviral expression system. Alterations in mRNA profiles in the MEG3-overexpressed cells were analyzed by RNA-seq. The cell invasion ability was measured using a Transwell assay, and the EMT-associated proteins were quantified by immunofluorescence and western blot. Finally, a tumor cell xenograft mouse model was applied to verify the effect of MEG3 on tumor growth and invasiveness. The percentage of invasive tumors was significantly declined in GNAS-mutated GHPA tumors with the GNAS mutations compared to those tumors with the wild-type of GNAS. Consistently, the GH3 cell invasion capacity was decreased by expressing the mutant GNAS. MEG3 is uniquely expressed at high levels in GHPA harboring the mutated GNAS gene. Accordingly, the upregulation of MEG3 resulted in inhibiting cell invasion; and vice versa, the downregulation of MEG3 led to enhancing cell invasion. Mechanistically, the high level of MEG3 in mutated GNAS cells prevented the cell invasion via inactivation of the Wnt/β-catenin signaling pathway, which was further validated in vivo. The GNAS mutations inhibit the invasiveness of GHPA cells via inactivation of the MEG3/Wnt/β-catenin signaling pathway.

Background: Glioblastoma multiforme (GBM) is a highly vascular-rich and devastatingly aggressive type of malignant brain tumors, thus anti-angiogenesis therapy plays an essential role in the treatment of GBM. Our previous study had showed that the prostate-specific membrane antigen (PSMA) promoted angiogenesis of GBM through interacting with Integrin β4 (ITGB4) and regulating NF-kB signaling pathway. This study aims to explore the upstream molecular mechanism of GBM regulating the expression of PSMA and promoting angiogenesis process.Methods: Human cytokine antibody array and bioinformatics were used to explore potential cytokines involved in regulating PSMA expression. Recombinant protein was applied and western blot, qRT-PCR were assessed to verify that the contributing cytokine was SPP1. Potential transcription factor mediating the expression of PSMA was sifted through PROMO and JASPAR website. ChIP assay and dual luciferase were used to confirm that the transcription factor HIF-1α could regulate PSMA expression. Cellular migration and tube formation ability were assessed by scratch assay and tube formation assay in human umbilical vein endothelial cells (HUVECs). ELISA was conducted to evaluate the variation of SPP1 in the serum of GBM patients pre- and post-surgery. Expression levels, prognosis and receiver operation characteristic (ROC) curve of SPP1 were determined by bioinformatics to evaluate its clinical value. Results: We demonstrated that cytokine SPP1 secreted from GBM could regulate the expression of PSMA in HUVEC. The mechanistic study revealed that SPP1 regulated the expression of PSMA through transcription factor HIF1α. Recombinant protein SPP1 could promote migration and tube formation ability of HUVEC, which could be blocked by knockdown of HIF1α. SPP1 was abundantly expressed in the GBM, and the high expression of SPP1 is associated with poor prognosis. Furthermore, SPP1 had a high value of clinical diagnosis with considerable sensitivity and specificity. Conclusions: In this study, we identified that upstream cytokine SPP1 secreted from GBM could upregulate PSMA expression in endothelial cells via transcription factor HIF1α, which constructs a positive chain in angiogenesis and provides promising candidates for targeted therapy of GBM.

Background: Different timelines are preferred for repair surgeries in patients with unilateral complete cleft lip and palate (UCLP). The aim of this study was to evaluate the effects of early palatoplasty on procedural related blood loss (anemia) and fistula formation in patients with UCLP. Methods: This randomized controlled trial conducted on patients candidate for UCLP repair. Patients in control group underwent cheiloplasty, closure of nasal floor, caudal septum dislocation repair, and primary rhinoplasty in first surgery at age of 28 days-4 months. In second surgery, patients in control group underwent two flap palatoplasty with vomerian flap and intravelar veloplasty, soft palate repair and also myringotomy at age of 9-12 month. In case group, infants underwent cleft lip and nose repair (like control group), hard palate repair in first surgery and then in second surgery, patients underwent soft palate repair with intravelarveloplasty. Results: Fifteen patients were included in each group. Two patients in primary surgery in the case group and two patients in secondary surgery in the control group were developed to oronasal fistula after palatoplasty (P= 0.432). The mean hemoglobin levels in the case and control groups at the primary surgery were 10.32±0.68 and 10.31±0.49 g/dL, respectively (P= 0.968) and at the secondary surgery were 11.29±0.54 and 11.37±0.40 g/dL, respectively (P= 0.666). Conclusion: There were no perioperative hemorrhagic events and need to blood transfusion in both groups. Early palatoplasty may as safe as conventional technique in patients with UCLP.Trial registration number: IRCT20180802040678N5

Background: Biliary disorders are still the most challenging cases in the field of gastroenterology, as comprehensive clinical evaluation and treatment considerations are still necessary. In the era of laparoscopic procedure, there are a lot of innovations on non-surgical management approaches, such as endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic ultrasound (EUS). Since there is no clear consensus yet in managing complicated biliary disorders, this study is aimed to see the impact of endoscopic management for difficult biliary cases. Methods: A cohort-retrospective endoscopy database study was conducted at a tertiary-referral private hospital in Jakarta, Indonesia, between January and December 2020. Difficult biliary cases defined as biliary case which required at least one of the following conditions: multi-management approach, biliary obstruction with cholangitis or biliary sepsis, difficult CBD stone, recurrent CBD stone, or advanced progressive malignant biliary obstruction. Results: Sixty-one subjects in this retrospective database study were suitable as difficult biliary cases. The proportions of malignant and non-malignant etiologies were similar (44.3% versus 55.7%, respectively). In this study, 68.8% of all subjects underwent standard therapeutic ERCP procedure, while 16.4% of the subjects underwent combination of therapeutic ERCP and EUS in one session based on the complexity of the case; and 8.2% of the subjects underwent therapeutic ERCP with additional single operator cholangioscopy procedure. One subject underwent rendezvous ERCP procedure through percutaneous approach. Around 4.9% of the subjects underwent EUS-biliary drainage procedure. The technical success rate of all procedures was 100%. Re-intervention ERCP was performed in 6 subjects (9.8%). No significant association was observed between all mortality outcomes and baseline characteristics of the patients. There were also no significant associations between re-intervention procedures, as well as post-procedural pain or acute pancreatitis, with mortality outcomes. Conclusion: Difficult biliary cases require a good clinical approach algorithm to decide which procedure comes first based on comprehensive evaluation consists of patient’s factor, expertise, cost, and the risk of complications.

Background: Colic pseudolipomatosis is a rare and benign condition of which many endoscopists and pathologists are unaware. Several pathogenic mechanisms have been postulated. For a better understanding and recognition of this uncommon lesion with particular attention to its etiology, we report and discuss a series of patients in whom colonic pseudolipomatosis was found during routine colonoscopy and occurring in an epidemic pattern.Methods: This was an observational cross-sectional study reporting a form of unprecedented colitis, colonic pseudolipomatosis, observed in a series of patients at our endoscopy center during a 3−month period in late 2021 (October - December). We collected demographic/clinical data, endoscopic and histological findings from all included patients. For statistical analysis, we used the simple method of ratio to provide percentagesResults: In total, eight patients were included. Their median age was 59,5 years with a male/female sex ratio of 0.6. During endoscopy, flat or slightly elevated whitish−yellow plaques extending from a few millimeters to several centimeters, were found in the colonic mucosa of all patients at variable sites. In three patients, a whitish foamy fluid appeared under our observation rapidly followed by the formation of whitish plaques when water was irrigated. Histological specimens showed in all cases, numerous optically empty vacuoles of variable size in the lamina propria. After confronting histological findings to endoscopic features, the diagnosis of pseudolipomatosis was made in all cases. The disinfectant we use contains hydrogen peroxide and peracetic acid. We found that our disinfectant machine had a technical malfunctioning in the rinse cycle of endoscope channels during this period. No further cases were observed after we serviced the machine. No patient subsequently suffered morbidity or mortality.Conclusion: Pseudolipomatosis seems to be an endoscopy induced lesion rather than a true pathological entity. The detection of such lesions should incite to a careful check of the disinfection process, thus, minimizing patients’ exposure to residual disinfecting agents in the endoscope and avoid further unnecessary investigations.
