Multi-stage hydraulic fracturing technology in a well with horizontal working face
Authors: Leontiev Dmitry , Shamsutdinov Nikolay , Vaganov Yuri , Shalyapina Adel , Shalyapin Denis , Zhigalkovskaya Maria
Published: March 2023

At present, hydraulic fracturing (HF) is still the most effective method of stimulating hydrocarbon flow and enhancing oil recovery in certain types of wells, particularly those with horizontal endings. In many regions, this is the only technology that enables development of fields with hard-to-recover reserves confined to low-permeability, poorly drained, heterogeneous and dissected reservoirs, which significantly increases hydrocarbon production and makes well construction economically viable. In this work, the authors have developed a new technology for interval hydraulic fracturing in a well with a horizontal target area, with the ability to inject fracturing fluid and hold excess pressure on either side of the fracturing unit by means of flap-type check valves. The fracturing is performed through a transport unit that runs directly through the casing and protects the plug from the abrasive effects of the gel-propellant mixture. After fracturing is complete, the transport unit is removed from the plug, and the rear cut-off valves are closed. No re-entry is possible after the adaptor has been removed from the well. For the next interval, the work cycle of plug, activation and fracturing is repeated using a new transport unit. For each repetition, the newly stimulated interval remains isolated until the fracturing operation is complete and all downstream plugs have been fractured. All installed plugs are drilled out before development. During all phases of the work, it is assumed that the well is prepared without the use of coiled tubing. The novelty and innovation lie in the technological solution of delivery to the target area and using easy-to-drill plugs to guarantee open interval separation and perform selective fracturing. Potential candidates are wells with 114 mm diameter casings with single- or multiple-acting fracturing sleeves to open-close after the horizontal part of the well has been prepared (the ‘equal-pass’ section requirement is for a 95 mm diameter bit). The proposed technical means and technology, in the opinion of the authors, will increase the efficiency of field development, reservoir conditions in which are characterized by low filtration parameters, high viscosity properties, etc. The authors do not think that the proposal will generally solve the problem of intensification of the inflow of reservoir fluid to the well and thereby increase oil recovery from the reservoir, but according to in their opinion, in some respects it will contribute to this. The final results will be obtained based on the results of extensive production tests.

Authors: Mladenov D. , Yordanov S. , Dimitrova A.
Published: March 2023

This article presents the results of studies on the use of the new macrolide antibiotic tulathromycin in veterinary medicine. The information is presented according to the species of domestic animals, diseases, doses and shemes for therapy and metaphylaxis. The first section includes data for cattle and calves affected by respiratory diseases, caused by M. haemolytica, M. bovis, H. somni and P. multocida, and keratoconjunctivitis caused by M. bovis. The second one shows data for swine and pigs affected by the respiratory pathogens A. pleuropneumoniae, P. multocida, H. parasuis, B. bronhiseptica and M. hyopneumoniae. A third group presents information about small ruminants with manifested respiratory diseases caused by M. haemolytica, P. multocida, Mycoplasma spp., Pseudomonas spp. and hoof diseases from Dehelobacter nodosus. Fourth group includes the first test results of Rhodococcus equi, Streptococcus zooepidemicus, Theileria equi, Babesia bovis and Babesia bigemina, causing diseases in horses. The fifth section includes reports of treated rabbits most commonly suffering from P. multocida respiratory infections. Finally, data from new studies on the use of tulathromycin in exotic animals and cases of some tropical diseases are listed. The provided information gives proof for the high sensitivity of the tested pathogens to tulathromycin and high clinical and economical effect that is efficient in single dose of 2.5 mg/kg. Compared to other antibacterial agents there is no resistance according to data available so far. Local accumulation and prolonged persistence of the drug in lung tissues, that result in a treatment regime with a single low-volume dose (2.5 mg/kg), are associated with positive clinical outcome in domestic animals: large ruminants, pigs, small ruminants and rabbits with respiratory diseases caused by M. haemolytica, H. somni, P. multocida and M. bovis; A. pleuropneumoniae, B. bronchiseptica, P. multocida, H. parasuis and M. hyopneumoniae; S.aureus, C. pseudotuberculosis and Streptococcus spp. and P.multocida

Published: March 2023

Generational Attitude measures the level of acceptance or non-acceptance of gay men in the community as perceived by them. This study's primary purpose is to determine the generational attitude of gays in Tagbilaran City, Bohol, Philippines. A quantitative research method was employed using a self-constructed questionnaire. Percentages, Weighted Mean, Chi-Square Test, ANOVA, and Spearman Rank Correlation were used to analyze the data collected. Overall results showed that the gay respondents' level of attitude yielded a Moderate Level of Acceptance. As a result of the survey's analysis, gay respondents think and believe that non-gays treat them appropriately. They feel that they are respected and accepted for their gay rights. The data revealed that there was a moderate level of acceptance of gay marriage. The findings of the study would form a basis for the intervention program. Moreover, the study lacked respondents who were not members of the LGBTQIA+ Community Tagbilaran. Additional research among gays who came out publicly but are not members of the LGBTQIA+ Community Tagbilaran must be conducted to validate the result of this study.

Authors:   Universidad de Buenos Aires (UBA), González Ricardo
Published: March 2023

The article concerns the issue of religious fraternities in colonial Buenos Aires: their existence and functioning as well as their influence on church furnishing in the region. Discussion begins with a short description of fraternities as religious institutions with emphasis placed on their social and culture-forming aspect. The article then presents a historical outline of the fraternities functioning in Buenos Aires: from the first ones, which appeared as early as in the late 16th century (Fraternity of Our Lady of the Rosary, 1586), to the late colonial ones originating from the 19th century (Fraternity of Souls in Purgatory, 1804). The text also describes chapels belonging to the fraternities and images associated their functioning as well as altars which were placed inside.
Hechos hierofánicos y experiencias místicas del sincretismo religioso en México
Authors:   Departamento de Filología Española Universidad de Łódź, Wendorf Anna
Published: March 2023

One of the most precious aspects of the research into Latin American cultures is undoubtedly religious experience, in regard to both its variety and diversity. Thus, this paper handles the events and situations which are inseparably connected with development of religious syncretism in Mexico. The article analyses historical conditions of syncretisation processes, American Indians’ beliefs, ceremonies and rituals, with particular consideration of Day of the Dead and cult of Our Lady of Guadalupe. The study of diachronic and synchronic profile does not claim the right to periodization of these experiences. It only aims at inquiring into social and cultural circumstances, allowing these cultures to interpret the world in a different way
¿Cidade maravillosa? La imagen de las favelas de Río de Janeiro – desde el cine artístico hasta el popular
Authors:   Universidad de Łódź (UŁ) Sociedad Polaca de Estudios Latinoamericanos, Kotarski Jędrzej
Published: March 2023

The article presents the evolution of favela’s images in Brazilian cinematography; from the first productions from the 1950s until the end of the first decade of the 21st century. The author tries to systematize them by distinguishing three periods (the 50s / 60s, the turn of the 20th and 21st centuries, the first decade of 21st century). The author discusses the change of the subject matter and the image of favela’s residents: from paternalistic images of alienation, otherness and mutual distrust, through homeliness, to relationships dominated by the world of crime at the beginning of the 21st century. Cinematography is like a mirror reflecting socio-political changes which took place in Brazil and affected its inhabitants in abovementioned periods. The analysis of these changes reveals their direction and nature which focus, like in the lens, on example of Rio de Janeiro.
The role of race relations in the Brazilian labor market: recruitment and selection processes in focus
Authors: Ferreira Cláudia Aparecida Avelar , Nunes Simone Costa , Santos Jair Nascimento
Published: March 2023

Abstract The aim is analyzing the race relations present in Brazilian society intersect gender and social class, and have an influence on the insertion in the formal labor market of black and white women through discourses of female students, and agents of Brazilian companies which capture professionals for their own company or for national and international other companies. The study adopts the qualitative approach. It uses the corpus of 26 discourses that encompass the linguistic-textual-discursive factors imbricated in the referencing process and in the construction of meanings, borrowed from Bakhtinian dialogism and Circle. The metanarratives of the agents of the companies emphasize race relations in the labor market, in line with the myth of racial democracy, meritocracy and the low schooling of women. The female students argue racism, sexism and social class as barrier to get a job in private labor market.
Flexible work as a rule in capitalism: conceptualization and theoretical-analytical propositions
Authors: Tessarini Junior Geraldo , Saltorato Patrícia , Rosa Kaio Lucas da Silva
Published: March 2023

Abstract This essay aims to explore flexible work in the context of flexible capitalism to propose a theoretical-analytical model of the different classifications of this phenomenon. From a critical literature review, we present fundamental problems - understanding the multiple manifestations of flexibility and how they affect workers and their productive practices. The proposed model comprises three interdependent analytical levels: contractual flexibility, functional flexibility, and workplace flexibility and flexitime. Each level has two subcategories that classify and analyze a work activity in terms of working arrangements, remuneration, tasks, autonomy, where work is accomplished, and work scheduling. Throughout this theoretical essay, we present an alternative definition to the concept of flexible work and argue that flexibilization is a phenomenon incompatible with the enhancement of the labor process in favor of workers and represents another movement of conflict between capital and labor. Therefore, flexibilization is configured in a mechanism of exploitation of workers and expansion of the labor force’s productivity in search of greater private accumulation of capital.

It is expected that, at the end of the case discussion, students will be able to achieve the following learning objectives: (a) understand the platform business model (b) understand the exponential nature of digital platforms; (c) understand the business ecosystem concept; (d) understand the concept of adjacency of digital platforms; (e) understand envelopment strategies.
Efeito da transparência e do capital social na intenção de mobilizar recursos
Authors: Tondolo Rosana da Rosa Portella , Tondolo Vilmar Antonio Gonçalves , Bitencourt Cláudia Cristina , Paiva Ely Laureano
Published: March 2023

Resumo O objetivo, neste artigo, consistiu em analisar o efeito da transparência e o efeito moderador do capital social na intenção dos gestores de Organizações da Sociedade Civil (OSCs) quanto à mobilização de recursos. Para atender ao objetivo, foi realizado um experimento, entre sujeitos, baseado em vinhetas, com 92 gestores de OSCs. Por meio do experimento, os gestores foram submetidos à decisão de aceitar apoio financeiro de um patrocinador com vistas a viabilizar a participação em um edital de concessão de recursos para desenvolvimento de projetos sociais. Os resultados evidenciam que o gestor da OSC está mais propenso a mobilizar recursos quando o patrocinador apresenta transparência em suas ações e que o capital social entre o gestor e o patrocinador não modera a relação entre transparência e a intenção de mobilizar recursos. Como principais contribuições, o estudo demonstra o papel do gestor da OSC como tomador de decisão.
Effect of transparency and social capital on fundraising intentions
Authors: Tondolo Rosana da Rosa Portella , Tondolo Vilmar Antonio Gonçalves , Bitencourt Cláudia Cristina , Paiva Ely Laureano
Published: March 2023

Abstract This article analyzes the effect of transparency and the moderating effect of social capital in Civil Society Organization (CSO) managers’ fundraising intentions. An experiment was carried out based on vignettes, with 92 CSO managers. Through the experiment, managers were asked to accept or decline financial support from a sponsor to enable participation in a public call for proposals to develop social projects. The results show that CSO managers are more likely to raise funds when the sponsor shows transparency in their actions and that the social capital between the manager and sponsor does not moderate the relationship between transparency and fundraising intentions. The study’s main contribution is that it demonstrates the role of the CSO manager as a decision-maker.
Fake news e storytelling: dois lados da mesma moeda ou duas moedas com lados iguais?
Authors: Girão Mel , Irigaray Hélio Arthur Reis , Stocker Fabricio
Published: March 2023

Resumo Fake news e storytelling têm sido abordados como constructos totalmente diferentes. As primeiras seriam intencionalmente e comprovadamente falsas; já o mesmo não se pode dizer do storytelling, cujas veracidade e autenticidade não são facilmente verificáveis. Todavia, tanto uma narrativa quanto a outra podem enganar os leitores e ambas estão inseridas em um contexto social e histórico que atua como fator regulador do processo de produção, circulação e recepção de discursos. Por isso, neste ensaio, defendemos a ideia de que, na sua essência, tanto as narrativas que compõem as fake news quanto as que formam o storytelling são duas moedas iguais, por guardarem similaridades nos processos de confecção e reprodução e, principalmente, nas suas motivações ulteriores, cujo objetivo final é a manutenção ou obtenção de capital econômico, social ou político.
Fake news and storytelling: two sides of the same coin or two equal coins?
Authors: Girão Mel , Irigaray Hélio Arthur Reis , Stocker Fabricio
Published: March 2023

Abstract Fake news and storytelling have been approached as completely different constructs. The former is intentionally and demonstrably false or misleading information, whereas storytelling produces a narrative with veracity and authenticity that are not easily verifiable. However, both can deceive readers and are inserted within a social and historical context that contributes to regulating discourse production, circulation, and reception. This essay advocates the idea that, in essence, fake news and storytelling narratives are two equal coins, similar in the processes of making and reproducing information and, mainly, in their goal of obtaining and maintaining economic, social, or political capital.
Ornamental cherry tomatoes in different protected environments and reflector materials in cultivation Bench
Authors: Campos Ruth S. de , Costa Edilson , Cavalcante Daniele F. , Freitas Rodolfo A. , Binotti Flávio F. da S.
Published: March 2023

ABSTRACT The study aimed to evaluate the growth of ornamental cherry tomato plants in different protected environments and reflective materials on the cultivation benches. As there were no repetitions of the protected environments, each environment was considered an experiment. In each environment, the experimental design used was completely randomized with five replications and three plants per plot. From the analysis of individual variances and evaluation of the mean squares of residues smaller than seven, the joint analysis of variance was performed (three protected environments x three reflective materials on the cultivation bench + 1 control without material). The protected environments evaluated were the agricultural greenhouse with a screen of 42-50% shading under the film, the agricultural screenhouse with a black screen of 30% shading, and the agricultural screenhouse with an aluminized screen of 35% shading. The reflective materials on the cultivation bench were Aluminet®, white Formica laminate, and red Formica laminate. The different protected environments influenced the growth of plants, and due to the lower incident light, the plants showed greater height in the agricultural greenhouse (42-50% shading). The reflective benches did not interfere with plant height but favored fruit production. The agricultural greenhouse (42-50% shading)) stands among the environments. For the reflective materials on the bench, aluminized fabric and red Formica laminate stood out, as they favored the growth of cherry tomato plants with desirable ornamental traits, such as greater fruit production.
Nutrients in lettuce production in aquaponics with tilapia fish compared to that with hydroponics
Authors: Duarte Eglerson , Silva Enilson de B. , Moreira Fernanda da C. , Braga Dermeval , Santos Shara G. dos
Published: March 2023

ABSTRACT In aquaponic systems, the residual water from the cultivation of fish is not enough to meet the nutritional demands of plants. The main objective of this study was to investigate how to adjust a nutritive solution for the cultivation of lettuce (Lactuca sativa L.) in aquaponics, based on hydroponics. The treatments included six separate crops of lettuce in an aquaponic system, while the hydroponic system served as the control. In each treatment, three blocks were used to quantify the parameters of ‘head’ diameter, number and dry weight of leaves, shoot dry weight, root dry weight, total dry weight, and the concentration and accumulation of nutrients in the total dry weight of the lettuce plants. The lower nutrient supply led to the occurrence of the lowest total dry weight in the C2 leaf crops when compared to that of the other crops of aquaponics, which had adequate time for system maturation. The system maturation and the use of a balanced solution in the C5 and C6 crops allowed the head diameter of the aquaponics plants to be equal to those of the hydroponics plants. In the aquaponic system, N and Fe were the most limiting macronutrient and micronutrient, respectively. To produce lettuce in an aquaponic system, it is necessary to ‘ripen’ the crop water for at least 30 days, and supplement micronutrients in the form of mineral fertiliser.

ABSTRACT Objectives: Evaluate the treatment outcome and the performance of the uCentum spinal fixation system in treating traumatic, degenerative, and tumoral diseases of the spine. Methods: This is a therapeutic study to investigate treatment outcomes and level of evidence III, including twenty-three adult patients of both sexes undergoing surgical treatment of degenerative (13 patients), traumatic (04 patients), or tumor diseases (06 patients). Patients were prospectively evaluated using clinical parameters: pain (visual analog scale), clinical and functional assessment questionnaires (SF-36, Oswestry and Roland-Morris), and radiological criteria (arthrodesis consolidation, loosening, breakage or deformation of the implants). Results: Twenty patients were followed for a period of 01 month to 12 month (mean 6,5±7,77). Three patients died due to complications unrelated to the primary disease (traumatic brain injury, septicemia, and lung tumor). Improvements were observed in clinical parameters and scores of the evaluation questionnaires used. No implant-related complications (breakage, loosening, deformation) were observed. Conclusion: the uCentum fixation system showed great versatility for performing the surgical treatment, allowing the performance of open, percutaneous procedures, the introduction of acrylic cement inside the implants, and conversion of polyaxial screws into monoaxial screws intraoperatively.

Liability Regimes in the Age of AI: a Use-Case Driven Analysis of the Burden of Proof
Authors: Fernández Llorca David , Charisi Vicky , Hamon Ronan , Sánchez Ignacio , Gómez Emilia
Published: March 2023

New emerging technologies powered by Artificial Intelligence (AI) have the potential to disruptively transform our societies for the better. In particular, data-driven learning approaches (i.e., Machine Learning (ML)) have been a true revolution in the advancement of multiple technologies in various application domains. But at the same time there is growing concern about certain intrinsic characteristics of these methodologies that carry potential risks to both safety and fundamental rights. Although there are mechanisms in the adoption process to minimize these risks (e.g., safety regulations), these do not exclude the possibility of harm occurring, and if this happens, victims should be able to seek compensation. Liability regimes will therefore play a key role in ensuring basic protection for victims using or interacting with these systems. However, the same characteristics that make AI systems inherently risky, such as lack of causality, opacity, unpredictability or their self and continuous learning capabilities, may lead to considerable difficulties when it comes to proving causation. This paper presents three case studies, as well as the methodology to reach them, that illustrate these difficulties. Specifically, we address the cases of cleaning robots, delivery drones and robots in education. The outcome of the proposed analysis suggests the need to revise liability regimes to alleviate the burden of proof on victims in cases involving AI technologies.

A Study on Media Content for Global Citizenship in English Education: A Focus on the Documentary Side by Side: Out of a South Korean Orphanage and Into the World
Authors: Cha Minyoung
Published: March 2023

The purpose of this study is to analyze the contents of the documentary, Side by Side: Out of a South Korean Orphanage and into the World (Glenn & Julie, 2018), as a form of media content for global citizenship education, and to examine the validity of its utilization. This documentary proposes an improved awareness of transnational adoption and a new awareness of the issue through creative directing and innovative screening methods. Utilizing media contents such as documentaries, students objectify social issues and materialize the recognition of problems and their solutions independently. This can be used as an effective approach to improve global citizenship in English education targeting the MZ generation who are actively open to media and digital environments. Above all, watching Side by Side: Out of a South Korean Orphanage and into the World and discussing the adoption discourse will be an opportunity for students to develop their multicultural sensitivity and learn the virtues of being human. Furthermore, it will find whether this documentary is appropriate for practicing the core areas of global citizenship and global citizenship education presented by UNESCO (2015) and could be considered a basic study for future English class design and learning outcomes.
ENDÜLÜS EMEVÎ HALİFESİ III. ABDURRAHMAN’IN SIMANCAS YENİLGİSİ (939)
Authors: KÜSKÜ Orhun
Published: March 2023

Endülüs Emevî Devleti’nin sekizinci hükümdarı ve ilk halifesi olan III. Abdurrahman, uzun süren iktidarının sağladığı avantajın yanında sergilediği üstün yönetim becerileri sayesinde İslâm ve Dünya tarihinde başarılı idareciler arasında yer almıştır. İktidarının başlangıcında karşılaştığı zorlukları uzunca uğraşlar sonrası bertaraf etmeyi başaran Endülüs Halifesi, İber Yarımadası’nın kuzeyindeki Hristiyan krallıklara karşı da aynı başarıyı göstermiştir. Lakin devletin gücüne güç katan ve hatta halifelik makamıyla gücünü perçinleyen Abdurrahman en-Nâsır’ın 939 yılında Simancas’ta León Kralı II. Ramiro’ya karşı kritik bir mağlubiyeti vardır. Saltanatının ilk otuz yılında merkeziyetçi bir yönetim modelini ortaya koymak için çabalayan en-Nâsır, bu uğurdaki uygulamaları sebebiyle özerkliklerine düşkün olan sınır bölgelerindeki yönetici soylu ailelerin öfkesini üzerine çekmiştir. Ayrıca halifenin Arapların ordu içindeki nüfuzlarını sınırlandırmak için önemli mevkilere Arap olmayan Slav kökenli kimseleri yerleştirmesi, Kurtuba Hilafetine karşı başka bir gayrimemnun grubun peyda olmasına yol açmıştır. Böylesi bir atmosferde Endülüs Emevî hükümdarının Hristiyanlar üzerine cihat çağrısıyla savaşa gitmesi, İslâm ordusunun çokluğunun anlamını yitirmesine ve neticede -Hristiyanların önceden hazırladığı hendeğin de etkisiyle- ağır bir yenilginin yaşanmasına sebep olmuştur. Bununla beraber Simancas bozgununun süreçleri ve Endülüs Emevîleri üzerindeki etkileri genel olarak tartışmalı olsa da III. Abdurrahman’ın siyasetinde kayda değer değişikliklerin meydana geldiği aşikârdır.

Authors: GÜRLER Cem
Published: March 2023

Crowdfunding platforms determine different strategies to attract more backers and fundraiser. Although the product itself is a project in crowdfunding projects, it can be said that the platform is as important as the project. This study aims to rank the factors affecting the choice of crowdfunding web sites with analytic hierarchy process. For this purpose, four dimensions (tangibles, reliability, assurance, integration of communication) and ten criteria (usability, design, navigability, standardization, reputation, relevancy, authority, privacy, FAQ’s and help, inclusion of special services) were included in the analysis. 11 people knowledgeable about crowdfunding were reached to ask pairwise comparisons. For this purpose, a survey was created. Surveys were sent and collected via email. The data used in the study were collected from three different groups: academics, backers, and a fundraiser. AHP results revealed that most important dimension was reliability. Moreover, according to the calculated general weights, the most important criterion is privacy, while the least important criterion is design.

Genellikle insanlar doğumdan itibaren toplumsal cinsiyet rollerine maruz kalarak ilerleyen yaşantılarında bu roller doğrultusunda tüketim tercihlerini ve kararlarını belirlemeye çalışmaktadır. Toplumdan topluma değişen söz konusu bu roller, kişilerin vereceği tüketim kararlarında etkili bir pozisyonda yer almasını sağlayabilir. Ancak daha önce yapılmış çalışmalar, küresel bir şokun tüketimler üzerinde bireylerin benzer tüketim tercihlerinde bulunulduğunu göstermiştir. Bu bağlamda çalışmanın amacı Covid-19 salgını ile birlikte toplumun cinsiyetlere yüklediği rollere ait tüketim kalıplarının genç yetişkinler üzerindeki değişiminin ne şekilde yaşandığını ortaya koymayı amaçlamaktadır. Araştırma yöntemi olarak nitel araştırma tekniklerinden derinlemesine mülakat tekniği kullanılmıştır. Çalışma kapsamında Muğla Sıtkı Koçman Üniversitesi İktisadi ve İdari Bilimler Fakültesi bünyesinde yer alan bölümlerdeki (işletme, iktisat, kamu yönetimi, siyaset bilimleri ve uluslararası ilişkiler) 40 öğrenci ile bu görüşmeler gerçekleştirilmiştir. Sonuç olarak küresel salgınla birlikte toplumsal cinsiyet algısına aykırı satın alımlar gerçekleştiren katılımcıların son derece az oluşu hatta genç yetişkinlerin büyük çoğunluğunun toplumsal cinsiyete bağlı tüketim yapmadıkları ve buna karşı oldukları ortaya çıkmıştır.
O Legado da Memória Coletiva na Cultura Digital: Digitalização, Mapeamento Cultural e Cocriação
Authors: Velhinho Ana , Almeida Pedro
Published: March 2023

Em plena transição digital, na qual o património digital emerge como resposta a uma necessidade de preservação e gestão da informação cultural numa era de produção acelerada e desregulada, o mapeamento cultural destaca-se como abordagem agregadora e multidisciplinar que convoca à participação. Neste contexto, o design afirma-se como mediador entre múltiplas disciplinas, tornando-se cada vez menos centralizado na materialização de objetos como finalidade, em favor da implementação de processos de cocriação e ativação de sistemas sociotécnicos que congregam pessoas, contextos e tecnologia. Neste âmbito, destaca-se a preservação e dinamização do património cultural, que tem vindo a estar institucionalmente a cargo dos museus, bibliotecas e arquivos, responsáveis pela recolha, preservação e disponibilização à comunidade. O presente artigo evidencia o impacto da digitalização da cultura e das políticas de acesso aberto nas instituições da memória, em termos de gestão das coleções e de experiências de fruição dentro e fora das instituições com recurso à tecnologia, bem como apresenta metodologias de participação ativa de comunidades na documentação e salvaguarda do património cultural imaterial, com destaque para várias iniciativas, em particular desenvolvidas em Portugal.
On Λ-fractional variational calculus
Authors: KA Lazopoulos , AK Lazopoulos
Published: March 2023

Pointing out that Λ-fractional analysis is the unique fractional calculus theory including mathematically acceptable fractional derivatives, variational calculus for Λ-fractional analysis is established. Since Λ-fractional analysis is a non-local procedure, global extremals are only accepted. That means the extremals should satisfy not only the Euler–Lagrange equation but also the additional Weierstrass-Erdmann corner conditions. Hence non-local stability criteria are introduced. The proposed variational procedure is applied to any branch of physics, mechanics, biomechanics, etc. The present analysis is applied to the Λ-fractional refraction of light.
ONT Sequencing IT/Compute Pop!_OS 22.04 Setup v2
Authors: Douglas Russell Stephen
Published: March 2023

The IT requirements for processing MinION data should be carefully reviewed before purchasing a MinION device. You will want to go with a Linux system. System76 is really the primary/best vendor for laptops. Pay careful attention to the GPU. It is probably the most important component for fast processing of the data. Here is is a link to a Facebook thread of some discussion when first considering the specs required. Setting up all of the programs/dependencies, particularly for utilizing the GPU during the analytical workflows is the next important step. You will want to get all of this in place before you start with the lab workflows, as there are many things that could go wrong or that you will need to work through in order for you to be able to actually begin a run.
Extraction of Yeast High-Molecular-Weight Genomic DNA v1
Authors: L. Hoyer Lois
Published: March 2023

This protocol is used for extraction of high-molecular-weight genomic DNA from yeast cells such as Candida albicans. We have used the protocol successfully for other fungal species such as Emydomyces testavorans that have considerably different incubation conditions and growth kinetics than C. albicans. The resulting DNA is suitable for long-read genome sequencing as well as many other applications. The protocol uses Zymolyase to spheroplast fungal cells, followed by phenol/chloroform extraction and isopropanol precipitation to collect the genomic DNA. The protocol is scaled for cultured yeast cells in a 50-ml volume. Starting with a large number of cells allows DNA yield to be sacrificed at each step in favor of purity and gentle handling of the preparation. The protocol was based on the method from the Laboratory Course Manual for Methods in Yeast Genetics (Cold Spring Harbor Laboratory, 1986; see References). Modification and addition of protocol steps were made over the years, evolving into the protocol presented here which is a standard method in the Hoyer Laboratory.
Bloqueo de los nervios iliohipogástrico e ilioinguinal para analgesia posquirúrgica en cesárea tipo Pfannenstiel realizada bajo anestesia general: ¿qué concentración del anestésico local usar?
Authors: García Alberto Paulo , Custode Vivanco Francisco Javier , Martínez Castaño Vasti , Millán Trujillo Luis Alberto , García García Héctor Iván
Published: March 2023

El bloqueo bilateral de los nervios Iliohipogástrico e Ilioinguinal con bupivacaína al 0.5% puede proveer analgesia luego de cesárea con incisión de Pfannenstiel aunque la cantidad de droga usada está cerca de la dosis máxima segura. Diseñamos este estudio para comparar el efecto analgésico de la bupivacaína al 0.5% y diluida al 0.25%. Se incluyeron treinta pacientes aleatoriamente asignadas a un grupo de estudio (bupivacaína 0.25%, n= 15) y uno de control (bupivacaína 0.5%, n=15). Se evaluaron las pacientes con una Escala Visual Análoga (EVA) a las O, 4, 8, 12 y 24 horas posoperatorias por médicos que no sabían a qué grupo pertenecían y sólo en caso de necesidad se prescribió analgesia IM con Diclofenaco. Los puntajes de analgesia y los requerimientos de analgesia complementaria fueron notoriamente similares en ambos grupos y no hubo diferencias estadísticamente significativas. Concluimos que el bloqueo de estos nervios es una técnica analgésica efectiva (el dolor siempre estuvo en promedio por debajo de 4 en la EVA), que no es afectada por la dilución del anestésico y que además es segura pues no se presentaron complicaciones.

El propósito de este trabajo fue demostrar la circulación de los virus de influenza en la ciudad de Medellín. Se estudiaron 15 pacientes y 15 controles, titulando sus anticuerpos séricos mediante la prueba de Inhibición de la Hemaglutinación (IH). En 8 pacientes (53,3%) se encontró alza o disminución cuádruple o mayor de los títulos. La positividad por subtipo fue de 62,5% para A/ (H1 N1 ), 25% para A/(H3N2) y 12,5% para influenza B. Los títulos estables ≥ 40 se consideraron como evidencia de infección previa o de circulación reciente del virus y se encontraron distribuidos así: Para A/(H3N2) 53,3% en los pacientes y 80% en los controles; para A/(H1N1) 100% en cada uno de los grupos y para B, 6,7% en los pacientes y 13,4% en los controles. Este informe sugiere una mayor circulación reciente de una cepa A/(H1 N1 ). Los virus tipo B no parecen haber circulado en la población por un período prolongado ya que los ancianos no mostraron evidencia serológica de ello. En conclusión pudo observarse la circulación simultánea de las dos cepas A estudiadas, con predominio de la A/(H1 N1 ). Sería recomendable mantener la vigilancia permanente de estos virus para poder aplicar medidas preventivas y de tratamiento oportuno.
La p67-PHOX como un elemento esencial del sistema NADPH oxidasa de las células fagocíticas
Authors: Avendaño Claudia Patricia , Patiño Grajales Pablo Javier
Published: March 2023

Las células fagocíticas cumplen un papel fundamental en la defensa innata del huésped contra la invasión de microorganismosL. uegod e ser fagocitados, uno de lo~ mecanismos utilizados para destruir dichos microorganismos es la producción de metabolitos intermedios del oxígeno generados a través del sistema NADPH oxidasa. Los radicales libres del oxígeno están al mismo tiempo involucrados en el daño tisular, que ocurre en muchas condiciones inflamatorias. La NADPH oxidasa es un complejo proteico conformado por varios componentes: gp91-phox y p22-phox, los cuales forman un heterodímero llamado citocromo b558q1u e se encuentra en la membrana de las células fagocíticas, y por las proteínas p47-phox, p67-phox y p40-phox que forman un complejo macromolecular localizado en el citoplasma. Durante la activación de las células fagocíticas los componentes citosólicos del sistema se translocan a la membrana y se unen al citocromo b558c'o nformandoa sí el complejo enzimático activo de la NADPH oxidasa cuya importancia biológica se ha evidenciado en las últimas cuatro décadas gracias al estudio de la enfermedad granulomatosa crónica (EGC). Ésta es una inmunodeficienciap rimariac aracterizadap or infecciones recurrentes y severas. Todos los casos de EGC reportados hasta ahora tienen que ver con una alteración en los genes que codifican las proteínas gp91-phox, p22-phox, p67-phoxy p47-phox. La p67 -phox es uno de los componentes del sistema NADPH oxidasa que más ha llamado la atención en los últimos años, pues tiene un papel fundamental en la activación del flujo de electrones desde el citoplasma a la vacuola fagocítica. En este articulo se hace una revisión acerca de lo que hasta ahora se conoce de la estructura y función de la p67-phox. Además se revisarán las diversas mutaciones identificadas en su gen, que debido a su alto grado de heterogeneidad son de gran utilidad para el entendimiento de la estructura y función del sistema NADPH oxidasa.

Published: March 2023

Entre agosto de 1989 y diciembre de 1991 se buscó asociación entre algunos factores de riesgo comunes a los prematuros con peso menor de 1.500 g al nacer y el hecho de presentar disminución de la agudeza auditiva, medida con los potenciales evocados del tallo cerebral a los 4 meses y luego entre los 8 y los 14 meses. Los factores de riesgo tenidos en cuenta en 133 prematuros del ";Programa madre canguro"; del Instituto de los Seguros Sociales, en Medellín, fueron: Peso inferior a 1.500 g, hiperbilirrubinemia superior a 10 mg/ml, sufrimiento fetal, membranas hialinas, uso de aminoglicósidos, hipoglucemia, hemorragia del tercer trimestre e hipertensión arterial materna. Se halló pérdida de la agudeza auditiva en la evaluación inicial en 54 nifíos (40.6%) mientras en la final sólo la presentaban 10 (7.5%); no pudo detectarse asociación entre los factores de riesgo y la disminución de la agudeza auditiva en la evaluación inicial ni en la final. La mejoría de resultados de agudeza auditiva entre las pruebas iniciales y las finales puede explicarse, entre otras razones, por la maduración cerebral del prematuro. Se debe investigar más la razón de los déficits finales y, ojalá, establecer programas de seguimiento con pruebas auditivas en este grupo de niños en riesgo.

Authors: Duque Alzate John Jairo
Published: March 2023

En 23 niños menores de 12 años que murieron en forma violenta sin haber recibido tratamiento, se estudiaron para Helicobacter pylori las mucosas gástricas con las coloraciones de hematoxilina eosina, Warthin Starry e inmunohistoquímica. Se encontró que 14 casos (60,9%) fueron positivos para esta bacteria, de los cuales 9 (64,3%) pertenecían a un estrato social bajo y 5 (35,7%) a uno medio. De los casos positivos para H. pylori, 9 tenían gastritis aguda, 1 gastritis crónica y sólo en 4 la mucosa gástrica era normal. Se observó una clara asociación entre H. pylori y cambios de gastritis.
