Authors: Mao Wei , Ding Xiaoqiang , Ding Yuqin , Fu Caixia , Zeng Mengsu , Zhou Jianjun
Published: September 2023

Background:

Chronic kidney disease has become one of the world's major public health problems, immunoglobulin A (IgA) nephropathy is a common pathological type of CKD. Delaying the progression of IgA nephropathy has currently become the main clinical treatment strategy, precise evaluation of renal pathological injury during follow-up of patients with IgA nephropathy is important. Therefore, it is imperative to develop an accurate and non-invasive imaging technique for effective follow-up of renal pathological injury in patients with IgA nephropathy.

Objective:

To investigate the clinical value of intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI) in assessing renal pathological injury in patients with immunoglobulin A (IgA) nephropathy compared with a mono-exponential model.

Methods:

Altogether, 80 patients with IgA nephropathy were divided into the mild (41 cases) andmoderate–severe (m–s) renal injury groups (39 cases) according to pathology scores, and 20 healthy volunteers were recruited as controls. All participants underwent IVIM-DWI of the kidneys, and renal parenchymal apparent diffusion coefficient (ADC), pure molecular diffusion coefficient (D), pseudo-diffusion coefficient (D*), and perfusion fraction (f) values were measured. One-way analysis of variance, receiver operating characteristic (ROC) curve analysis, and Pearson correlation analysis were performed for all the DWI-derived parameters.

Results:

The DWI-derived parameters of the m–s renal injury group were significantly lower than those of the mild renal injury and control groups (P < 0.01). The ROC analysis revealed that f had the largest area under the ROC curve for differentiation between the m–s and mild renal injury groups and between the m–s renal injury and control groups. The f had the largest correlation coefficient with renal pathology scores (r=−0.81), followed by the D* (−0.69), ADC (−0.54), and D values (−0.53), respectively (all P<0.01).

Conclusion:

IVIM-DWI demonstrated better diagnostic performance than the mono-exponential model in assessing renal pathological injury in patients with IgA nephropathy.
Comprehensive Overview of Apis mellifera Drone Development, Biology, and Interaction with The Queen
Authors: Marwaha Lovleen
Published: September 2023

The male honey bees, the reproductive caste of the colony, develop through
haploid/diploid parthenogenesis. The drones develop from haploid/ diploid unfertilized
eggs produced by parthenogenesis or from diploid fertilized eggs having identical sex
alleles, formed after sexual reproduction, with more probability when the queen honey
bee mates with the drones of the same hives. Therefore, two types of drone honey bees,
based on ploidy, are common in colonies, e.g. haploid or/and diploid. The number of
drone honey bees staying in the colony varies according to protein resources and the
strength of the worker honey bees. Generally, the haploid drone eggs/larvae laid by
workers are removed by the nurse bee due to cannibalism. The above-mentioned
eggs/larvae are marked with certain specific hormones that act as markers for
cannabalic removal of the same.

Further, the development of drones is influenced by colony temperature; hence overall
development can be completed within 24-25 days. The purpose of drone life is to
produce sperm and mate with the queen. The queen attracts the drone's honey bees
toward herself with pheromones 9-ODA, 9-HDA and 10 HDA. The drone number and
fertility depend upon the colony's environmental conditions, genomic possession and
available food in the colony. The specific chapter provides deep insight into the
development of drones, the biology of drones, the reproductive system, and the mating
behaviour of particular castes. Subsequent chapters highlight morphometric
characteristics of drones, development, mating, reproduction and artificial drone
production.
Nanocatalysts for the Photodegradation of Organic Pollutants
Authors: Pabel M.Y.
Published: September 2023

Industrial and other anthropogenic activities lead to increase in persistent organic pollutants (POPs) in natural water bodies. POPs are harmful to not only the aquatic ecosystem but also human health. Researchers around the globe have been working to develop efficient, cost-effective, environmentally-friendly methods for the treatment of contaminated waters. The chapter basically focuses on the removal of POPs by catalytic advanced oxidation processes (AOPs) using nontoxic metal oxides of d-block elements such as TiO2, ZnO, MnO2 and iron oxides nanomaterials and composites with different counterparts. An insight into the fundamentals of photocatalysis is highlighted. This chapter would bestow an opportunity to evaluate the underlying prospects of the methods involving AOPs used for the degradation of POPs dissolved in water.

Published: September 2023

This paper aims tp discuss the legitimacy of AIW at Nazhir Airlangga University from the perspective of the waqf law and whether it has complied with the principle of maslahah mursalah, considering that various cases of waqf property do not run optimally, are productive, are not used or are transferred to third parties. There is an interesting phenomenon, namely that at Nazhir, Airlangga University is the only one and the first time an Indonesian State University has received a Nazhir certificate to manage and develop waqf. In this case, it is interesting to discuss the practice of waqf at Nazhir Airlangga University according to the Waqf Law. This normative research uses statute approach and the conceptual approach. The results show that in practice Nazhir Universitas Airlangga in carrying out his waqf pledge practice does not use AIW un-authentic. That is, Nazhir Airlangga University in carrying out his waqf practice in terms of his pledge deed is in accordance with the procedures in accordance with Law Number 41 of 2004 concerning Waqf.
GOOD FAITH VERSUS BAD FAITH IN MITIGATING THE COVID-19 PANDEMIC IN INDONESIA
Authors: Rissy Yafet Yosafet Wilben
Published: September 2023

The COVID-19 pandemic has caused a real economic crisis across the globe, including Indonesia. To overcome this critical issue, the Indonesian President issued Government Regulation in Lieu of Law No. 1 of 2020 which was later stipulated as Law No. 2 of 2020 (the 2020 COVID-19 Emergency Law). This study applies a doctrinal legal research method. The result of the study shows that Article 17 of the 2020 COVID-19 Emergency Law grants the government officials the right of immunity to not be sued legally as long as their actions are in accordance with the good faith principle. Unfortunately, this law does not explain the meaning of good faith, so that it can become a grey area for the abuse of power. It is recommended that the government officials should be mindful in exercising their extraordinary powers based on the principle of good faith such as honesty, loyalty, trust, honour, a lack of fraudulent actions and conflict of interests, and adherence to the applicable laws to avoid an abuse of power and corruption in Indonesia.

In this dialogical article, PatrickCampbell and Adriana La Selva of international research platform CrossPollination interview Eugenio Barba and Julia Varley of Odin Teatret, with afocus on the activities of the recently inaugurated NGO Fondazione BarbaVarley. Having left their institutional base, Nordisk Teaterlaboratorium, inDecember 2022 after 56 years of being rooted to a concrete theatrical space,Odin Teatret now work nomadically, developing new projects both within Denmarkand beyond. The Fondazione Barba Varley extends and builds on the legacy ofOdin Teatret, with a specific agenda to support and promote the “nameless” –theatre groups and independent artists working silently on the borders betweentheatre and activism. Derrida’s writings around the politics of friendship(Derrida 2005) serve as a loose critical framework for articulating thepotential dialogical avenues available once one abandons the appropriativedrive of institutionalisation. The conversation follows an organic flow, with afocus on dialogue and communication, the embodied dialogical tactics of thetheatre laboratory practitioner, and the current activities of the Fondazione,such as the Constellation of the Nameless, ISTA New Generation, The Journal ofTheatre Anthropology (JTA) and the Living Archive: Floating Islands. Theatricallegacy and its transmission are articulated as relational and interpersonal,grounded on a deeply personal process of “creating signs”: the generation ofpoetic forms that translate a pragmatic know-how forged over a lifetimededicated to art as activism.

Se concluye que hay una gran heterogeneidad entre países y regiones, y el índice de percepción de la corrupción es uno de los indicadores que genera mayor diferenciación. También se delimitan seis clústeres de países por situaciones similares, que permiten resumir los retos que enfrentan los países para fomentar la paz, la justicia y la constitución de instituciones gubernamentales sólidas.
Políticas de comercio exterior
Authors: Baena-Rojas Jose Jaime , Mackenzie-Torres Tania Margarita , Guerrero-Molina María Isabel
Published: September 2023

A mediados de la década de 1990 México ingresó al sistema multilateral de comercio afianzando su liberalización comercial a través de una serie de políticas internas de comercio exterior. Esto consolidó la exportación de bienes terminados y diversas materias primas, que convierten ese mercado en uno de los más importantes de Latinoamérica. Este artículo identifica algunas de dichas políticas de comercio exterior caracterizando el comportamiento diacrónico de las exportaciones. Por ello, este trabajo, esencialmente descriptivo, considera bases de datos oficiales secundarias, a escala tanto local como internacional. Se concluye que entre los productos que más inciden en el total de las exportaciones de México sobresalen algunos sectores como bebidas, tecnología, electrodomésticos y automóviles, además de sectores como materias primas mineras y agrícolas. Todos ellos tienen un notable protagonismo respecto a otros países.

Firearm Possession Rates in Home Countries and Firearm Suicide Rates Among US- and Foreign-Born Suicide Decedents in the United States: Analysis of Combined Data from the National Violent Death Reporting System and the Small Arms Survey
Authors: Song In Han , Lee Jin Hyuk , Shin Jee Soo
Published: September 2023

Background

Suicide by firearms is a serious public health issue in the United States. However, little research has been conducted on the relationship between cultural backgrounds and suicide by firearms, specifically in those born and raised in the United States compared to those who have immigrated to the United States.

Objective

To better understand the relationship between cultural backgrounds and suicide, this study aimed to examine firearm suicide rates among US- and foreign-born suicide decedents based on the firearm possession rate in the decedent’s home country.

Methods

Multivariate logistic regression was performed to analyze data of 28,895 suicide decedents from 37 states obtained from the 2017 National Violent Death Reporting System data set. The firearm possession rate in the home countries of foreign-born suicide decedents was obtained from the 2017 Small Arms Survey.

Results

The firearm suicide rate was about twice as high among US-born suicide decedents compared to their foreign-born counterparts. Meanwhile, suicide by hanging was about 75% higher among foreign-born compared to US-born suicide decedents. Those from countries with a low-to-medium firearm possession rate were significantly less likely to use firearms compared to US-born suicide decedents (adjusted odds ratio [AOR]=0.45, 95% CI 0.31-0.65, and AOR=0.46, 95% CI 0.39-0.53, respectively). Meanwhile, firearm suicide rates were not different between US- and foreign-born suicide decedents from countries with a similarly high firearm possession rate.

Conclusions

The results suggest that there is an association between using firearms as a means of suicide and the firearm possession rate in the decedent’s home country. Suicide by firearms in the United States needs to be understood in the sociocultural context related to firearm possession.

Authors: Sa'id Iklil Iman Mohd , Hotung Natasha , Benton Madeleine , Nadal Iliatha Papachristou , Baharom Anisah , Prina Matthew , Nisak Mohd Yusoff Barakatun , Goldsmith Kimberley , Siew Mooi Ching , Forbes Angus , Ismail Khalida , Chew Boon How
Published: September 2023

BACKGROUND

Women with gestational diabetes mellitus (GDM) have an increased risk of developing type 2 diabetes mellitus (T2DM) later in life. Whilst diabetes prevention interventions (DPI) have been developed to delay or prevent the onset of T2DM, few studies have provided process evaluation (PE) data to assess the mechanisms of impact, quality of implementation or contextual factors that may influence the effectiveness of the intervention in practice. The aim of this review was to identify and evaluate PE data and how these link to outcomes of randomised control trials of T2DM prevention interventions for women with GDM.

OBJECTIVE

Specific objectives were to identify the extent to which PE components were reported and described in RCTs of DPIs for women with previous or current GDM and to assess whether these components could contribute to explaining the intervention outcomes of the DPIs.

METHODS

A systematic review was conducted to identify studies published from 2005–2020. Five electronic bibliographic databases (Cochrane Library, Cochrane Collaboration Registry of Controlled Trials, EMBASE, PubMed, and MEDLINE) were searched using the Medical Research Council’s PE framework of complex interventions to identify key PE components.

RESULTS

Twenty-four studies were included. Only five explicitly reported a PE theoretical framework. Whilst most studies linked PE data with study outcomes, it was unclear which of the reported PE components were specifically linked to the positive outcomes.

CONCLUSIONS

We need clearer guidance and robust frameworks for conducting PEs for the development and reporting of DPIs for women with GDM.

Authors: Che Qianzi , Song Tian , Liang Ning , Guo Jing , Chen Zhao , Liu Xiaoyu , Yang Lu , Jiang Yin , Wang Yanping , Shi Nannan
Published: September 2023

BACKGROUND

Although results from in vitro studies and small randomized controlled trials have shown positive effects of Dazhu hongjingtian injection (DZHJTI) on acute ischemic stroke (AIS), their generalizability to routine clinical practice remains to be established.

OBJECTIVE

The primary aim of this study is to evaluate the effectiveness of DZHJTI treatment for AIS with regard to changes in the stroke-related neurological deficit from baseline to outpatient follow-up, mortality, subsequent vascular events, disability, and traditional Chinese medicine syndrome in real-world clinical settings. By monitoring for adverse events or significant changes in vital signs and laboratory parameters, we also aim to assess the safety of DZHJTI.

METHODS

This prospective, multicenter cohort study plans to enroll 2000 patients with AIS within 14 days of symptom onset from 30 hospitals across China. Eligible patients will be followed up for 6 months after initiating medication treatments. The primary outcome will be the change in the National Institute of Health Stroke Scale score from baseline to outpatient follow-up. The secondary outcomes include overall mortality, stroke recurrence, new-onset major vascular events, global disability, and improvement of traditional Chinese medicine syndrome in 6 months. Adverse events or clinically significant changes in vital signs and laboratory parameters, regardless of the severity, will be recorded during the trial to assess the safety of DZHJTI. An augmented inverse propensity weighted estimator will be used to reduce variability and improve accuracy in average treatment effects estimation.

RESULTS

The clinical trial registration was approved in October 2022, and the recruitment and enrollment of participants started in November 2022. The study’s outcomes are expected to be published in 2025 in reputable, peer-reviewed health-related research journals.

CONCLUSIONS

This real-world cohort study is the first to assess the effectiveness and safety of DZHJTI in treating AIS. It may provide additional clinical evidence, including the duration of response, long-term drug effectiveness, and subgroup efficacy data. The study results will be valuable for clinicians and patients seeking optimal treatment for AIS and could lead to better use of DZHJTI and improved patient outcomes.

ChatGPT: Cognitive momentum or menace? (Preprint)
Authors: Ghosh Ritwik , Dubey Souvik , Jana Dubey Mahua , Chatterjee Subhankar , Das Shambaditya , Benito-León Julián
Published: September 2023

BACKGROUND

Students, teachers, corporate houses, and people from various streams have started using Chat Generative Pre-trained Transformer (ChatGPT) for already integrated information and writing. Discussions have already gained attention on ChatGPT, and some researchers also wanted to categorize this invention as a revolution.

OBJECTIVE

The authors try to elucidate the crosstalk between human cognition and Chat Generative Pre-trained Transformer (ChatGPT) and its impact on human cognition in the future.

METHODS

We searched through the PubMed, Embase, Web of Science, and Scopus databases with the following keywords (["Cognition" OR "Cognitive"] AND ["ChatGPT" OR "Chat Generative Pre-trained Transformer"]) up to 1 August 2023.

RESULTS

There are reports on literature deciphering how ChatGPT works and its prospects. However, there is a dearth of articles on how ChatGPT might affect human cognition reversely.

CONCLUSIONS

ChatGPT bears a broader perspective of artificial intelligence dedicated predominantly to several modalities assisted write-without-language barriers. The human brain works silently beyond the perception of most human beings, which is why its true potential often remains unacknowledged. We regularly do things (like reading or writing) that auto-activate numerous brain circuits to boost cognitive functions integrated. So, we should keep this practice intact and continue. We must not kneel before ChatGPT for the supreme cognitive abilities governed and given to us by Nature.

Introduction. The article focuses on the figure of Noyon (Prince) Tseren-David Tundutov, a most renowned Kalmyk nobleman whose multifaceted efforts were derived from the dramatic social upheavals and disturbances of the late nineteenth and early twentieth centuries. The topic still remains understudied since earlier works contained only insufficient data which made it virtually impossible to describe his personality in greater detail. Furthermore, the bulk of the former were published in the Soviet era, and the evaluations of Kalmyk noblemen’s endeavors are definitely to be revised. Goals. So, the paper aims to — wherever possible — extensively outline sociopolitical, economic, and household aspects of Noyon Ts.-D. Tundutov’s life. Materials and methods. The study basically employs both general scientific and special historical methods, with particular roles to be played by that of systems analysis and the principle of historicism that have proved instrumental in examining Noyon Ts.-D. Tundutov’s deeds contextually. The principle of objectivity has been secured by specially selected and compared sources of diverse origin, including some newly introduced material pertaining to records management. Results. Noyon Ts.-D. Tundutov was taking a most active part in solving social and political issues that arose from facts of the early twentieth-century Kalmyk life, namely: land and nationality questions, religious problems, economic affairs, and his endeavors as a deputy of the Imperial Duma. Special attention should be paid to the complete data on the Noyon’s real and personal property uniquely published herein. Conclusions. Despite the 1892 Reform had virtually deprived him of any subject commoners he succeeded in gaining opportunities for a successful development of his gardens and farms reported to have became diversified enough. In social and political life, he did achieve a status of somewhat ethnos-wide leader capable of demonstrating personal qualities required by the community in the early twentieth century.

Published: September 2023

Introduction. Evgeny A. Stulov (1902–1940) is a remarkable yet still little-known figure who invested extensive and fruitful efforts in Mongolia and for Mongolia. He came from a large peasant family but grew to receive sound training for that time which included real school courses followed by studies at Moscow University (External Affairs Department, Faculty of Social Science). On graduation, he was added to the reserve list of the People’s Commissariat of Foreign Trade (Administrative and Economic Department) to be further employed as economist (since August 1925) at the Chief Department of Tariffs (same Commissariat) — and soon promoted to Secretary of the Committee for Customs and Tariffs (CDT). Stulov’s expertise and competence were manifested in most diverse ways: he was writing scholarly articles, delivering lectures; as Advisor to the MPR Economic Council had to deal with the troubled situation in Arkhangai Aimag; and was in charge of Mongolia’s zoning. Goals. The study describes E. Stulov’s efforts dealing with Mongolia’s zoning, provides data on his articles and lectures. Materials. The paper investigates documents housed at Russian State Archive of the Economy, examines some published sources and scholarly writings. Results. Despite E. Stulov lived a short life (38 years only), his knowledge, competences, and accomplishments made it possible for him to gain a deep and practical understanding of the country and its citizens. As Advisor to the MPR Economic Council, he promptly delved into the circumstances behind the uprising in Arkhangai Aimag — and along with other researchers was further involved in zoning endeavors. Key outcomes of his work were approved and accepted by the Mongolian government. The scope of his activity also included writing of articles and lecturing. Our analysis attests to that he was well familiar with works authored both by predecessors and contemporaries , i.e. then and there we would face a man of individuality and talent who had accumulated good knowledge of Mongolia and actually done a lot for its future.
Strengthening of reinforced concrete structures by composite materials taking into consideration the carbonization of concrete
Authors: Rimshin Vladimir I. , Truntov Pavel S.
Published: September 2023

One of the main causes for deterioration of reinforced concrete structures in modern construction is corrosion of reinforcement. Corrosion leads to decrease of adhesion between reinforcement and concrete, formation of cracks and destruction of the protective layer of concrete. All this reduces the load-bearing capacity of reinforced concrete structures. The structures of sludge reservoirs exposed to carbon dioxide were used as an object of the study. The characteristic defects and damages revealed by visual inspection were described. The verification calculation of the considered construction depending on the pH of the medium was performed on the basis of the results of technical inspection and study. The degree of carbon dioxide impact on the considered structures was determined by the phenolphthalein test method, which is based on the color change of acid-base indicator solution on the surface of concrete and reinforced concrete depending on the pH value of its medium. The phenolphthalein test revealed that pH of the medium is less than 8 for the depth more than the thickness of the concrete protective layer. A verification calculation of the considered structure was performed on the basis of the technical inspection results and the conducted research. According to the calculation results, a variant of beam reconstruction and strengthening using external reinforcement based on carbon fibers FibARM 230/150 was proposed. The reconstruction was carried out with account of the carbonized concrete layer.

Authors: Krivoshapko Sergey N.
Published: September 2023

Superellipses are becoming more and more in demand in various branches of science and national economy due to their versatility. They found the most application in shipbuilding. Suggestions for the use of superellips in architecture and construction have appeared recently. The author proposes explicit and parametric equations of surfaces with a main framework of three predetermined superellips lying in three coordinate planes. These equations describe a large set of analytical shapes suitable for the formation middle surfaces of thin building shells. One of the superellipses is taken in a form of a circle. The shells can be designed on circular and rhombic plans, and also on plans in the shape of superellips of general type with convex and concave sides. All recommended surfaces are illustrated in 24 examples using computer graphics. A network of curvilinear non-orthogonal coordinates is generated on the surfaces using dimensionless independent parameters. The considered surfaces can become a part of the reserve of surfaces for further application in real structures and facilities.

Published: September 2023

The objective of the research is to study the effect of different additives on the conventional concrete. In this term, three types of materials have been added to the concrete: gelatin powder as the binder, recycled aggregates, and almond shell as the fine and coarse aggregates. Several experiments have been made tо determine physical and mechanical properties, such as test for compressive and tensile strengths, for impact loading strength, durability test (water absorption) and deep penetration tests. Moreover, the microstructure results for the new type of concrete have been studied by means of scanning electron microscopy (SEM) and energy-dispersive x-ray spectroscopy (EDXS). The results show that when 70 kg of gelatin powder is added to 1 m3 of concrete, the concrete’s compressive strength and tensile strength are improved more than 22%; during impact loading the first and ultimate cracks are 11 and 129 by numbers, and the first and ultimate cracks’ strength is more than 223 and 2346 J respectively. The durability of sample from concrete with additional gelatin has been improved. SEM results illustrate that the weakness of almond shell concrete is related to cracks and voids between the cement matrix and almond shell. The voids of gelatin concrete are higher than that of conventional concrete. The conventional concrete has smooth crystals, and gelatin concrete has sharp and cubic crystals. EDXS results show that chemical content of these two types of concrete is different: conventional concrete contains silicon, while EDXS results show that chemical content of these two types of concrete is different: conventional concrete contains silicon, while gelatin concrete contains calcium and also C-S-H gel is generated in it.

Construction dispute contributing to the involvement of billions US dollars in lawsuits and Asia was reported as the continent that had the highest dollars involved. Sarawak, the largest state in Malaysia, faced similar issues and such dispute had been reported in leading to cost and time overrun on the multiple large-scale construction projects. This research investigates factors causing dispute within Sarawak construction industry, by targeting G7 contractors, who has no limitation in handling the scale of project, by using simple random sampling method. Eighty-six contractors responded to the online questionnaire, amounting to 34% valid response rate. Descriptive statistics and Mann-Whitney U-test were used to investigate the viewpoint of respondents. The findings revealed that delay issue as the key cause of dispute to the contractors in Sarawak. Mann-Whitney U-test showed statistical significant differences on the perspectives of contractors between less than or equal to 10 years working experiences and more than 10 years experiences on four causes: poor cost management, finance issue, delay issue and different interpretation of contract provisions. This research could serve as a guideline for the contractors in handling dispute to improve construction companies’ profit margin and construction projects’ efficiency.
ENHANCING SECURITY OF RFID-ENABLED IOT SUPPLY CHAIN

Published: September 2023

In addition to its benefits, the popular Internet of Things (IoT) technology has also opened the way to novel security and privacy issues. The basis of IoT security and privacy starts with trust in the IoT hardware and its supply chain. Counterfeiting, cloning, tampering of hardware, theft, and lost issues in the IoT supply chain have to be addressed, in order to ensure reliable IoT industry growth. In four previous works, radio-frequency identification (RFID)-enabled solutions have been proposed by the same authors, aimed to bring security to the entire IoT supply chain. The works propose a new RFID-traceable hardware architecture, device authentication, and supply chain tracing procedure. In each of these works, a variant of the same is proposed. However, the same variant of lightweight RFID authentication protocol coupled with the offline supply chain proposed in these works has such security vulnerabilities that make the whole supply chain unsafe. In our present work, an online supply chain hop-tracking procedure supported by a novel RFID mutual authentication protocol, based on the strong matching of the RFID readers-their operators-central database present at the transfer hops is proposed. Our proposed Strong RFID Authentication Protocol (STRAP) has been verified by two well-accepted formal protocol analyzers Scyther and AVISPA. The verification results demonstrate that STRAP overcomes the previous works’ vulnerabilities. Furthermore, our proposed novel online supply chain tracing procedure supporting STRAP removes the previous offline supply chain tracing procedure weaknesses.
A pediatric case of portosystemic shunt presenting hypoxemia with brain abscess in an emergency department
Authors: Hwang Seong Taek , Park Jun Sung
Published: September 2023

Portosystemic shunt is a rare congenital vascular anomaly. The shunt is hard to clinically suspect because its symptoms develop insidiously and affect various systems at different time points. We report a case of an 11-year-old girl who presented with brain abscess and hypoxemia without respiratory distress. No abnormality related to the hypoxemia, such as intracardiac shunt, was found on the initial chest radiograph and echocardiogram. However, computed tomography showed a portosystemic shunt. An intrapulmonary shunt was demonstrated by bubble contrast echocardiography, indicating a grade 2 hepatopulmonary syndrome, a complication of portosystemic shunt. This case describes the diagnostic process of an unusual case presenting neurological abnormalities and hypoxemia without respiratory distress. Portosystemic shunt with hepatopulmonary syndrome should be considered in the differential diagnosis of unexplained hypoxemia.
A PRACTICAL ESTIMATION OF THE REQUIRED SAMPLE SIZE IN FMRI STUDIES
Authors: CANDEMİR Cemre
Published: September 2023

In functional Magnetic Resonance Imaging (fMRI) studies, the variability in fMRI data, the complexity of the analysis, and the need to correct for multiple comparisons make determining the appropriate sample size challenging. Hence, power analysis becomes an important tool to use for determining the appropriate sample size needed to achieve reliable and statistically significant results. In this context, this study aims to represent the process of conducting a power analysis and estimating the sample size for an fMRI study. To do this, three functional, affective, behavioral, and cognitive, data sets having different experimental task designs are used. This study provides a step-by-step guide on how to conduct a power analysis and estimate the sample size for various fMRI studies.
A ESCOLHA DE LIVROS DIDÁTICOS DE CIÊNCIAS DA NATUREZA NO ENSINO MÉDIO EM CONTEXTO DE IMPLEMENTAÇÃO DA BASE NACIONAL COMUM CURRICULAR: OS PROCESSOS E OS ESPAÇOS DE DECISÃO DOS DOCENTES
Authors: Pedreira Ana Júlia Lemos Alves , De Souza Rodrigo Diego
Published: September 2023

Este artigo tem foco nos processos e os espaços de escolha dos livros didáticos de Ciências da Natureza, pelos professores de Física, Química e Biologia, que atuam no Ensino Médio, via PNLD 2021, em contexto de implementação da BNCC. O objetivo da pesquisa, metodologicamente qualitativa, visou caracterizar esse processo a partir dos professores que atuam nessas disciplinas. O referencial que fundamentou este estudo consistiu na produção teórica sobre Livro Didático e Políticas Curriculares da área de Educação e Educação em Ciências. Participaram 102 professores das disciplinas da área. Concluiu-se que os espaços de escolha dos docentes, nesse processo, são limitados pelas condições de trabalho; pela não participação dos docentes na formulação das políticas e nas decisões sobre quais conhecimentos estão e não estão na escola; as limitações na presença e organização dos conhecimentos nos LD e o risco do empobrecimento da formação dos estudantes, mas, evidencia-se o comprometimento dos docentes com a formação dos estudantes diante das limitações.
Microstructure development in warm upset AM Ti64
Authors: Szczepanik Stefan , Nikiel Piotr
Published: September 2023

As AM Ti alloys generally contain porosity, for demanding applications it must be eliminated. HIP was reported, but it is expensive; accordingly forging by upsetting of EBM Ti6Al4V at 900?C was investigated. Strain rates of 0.01-1 s-1 were employed. In contrast to the as-printed material, porosity was not detected. From the plastometric tests the stress-true strain relationships were obtained and peak stresses were determined. Using the Simufact simulation program, details of the distribution of equivalent strains and temperatures were obtained. Comparison with wrought cast and printed materials is reported. The eventual microstructure consisted of alpha lamellae ranging in width from 1.81 to 2.34 ?m, depending on strain rate and deformation, and beta formed in the interlamellar space during cooling in air. The hardness of the fully processed material was in the range of 293-304 HV1, independently of strain rate. This is to be compared with EBM Ti64, 316-360 HV0.3, and similarly processed cast wrought material, 350-365 HV0.3.

Published: September 2023

The aim of this study was to investigate the effect of hexagonal boron nitride (h-BN) addition on copper based alloy system. Varying amounts of h-BN were added to the prepared metal matrix composition as a reinforcing material. The powder mixture was subjected to high-energy mechanical alloying and compacted under 400 N/mm2 and were sintered at 820?C for 2 hours. Following the sintering of the samples characterization procedures were performed after wear and friction testing. The addition of h-BN led to a decrease in dimensional shrinkage after sintering, while the difference between the achieved density and theoretical density increased. XRD results revealed the presence of characteristic peaks attributed to the reinforcement and metallic matrix. The wear tests revealed a significant increase in wear with higher h-BN content under different applied loads. The initial decline in friction coefficient with h-BN addition was followed by an increase as the h-BN content increased.
Understanding the Sustainability Reporting Landscape and Research Opportunities in Accounting
Authors: Dechow Patricia M.
Published: September 2023

I first distinguish the terms economic growth, economic development, and sustainable development. I then discuss the term ESG and why this term is used with respect to the corporation. I follow with a discussion of the shareholder primacy perspective and how this perspective plays a defining role in corporate law, corporate governance, and asset management. I argue that the shareholder primacy perspective is not appropriate for sustainability reporting because when a firm pollutes the environment, reduces biodiversity, or has inequitable social policies, it does not bear the full cost of its action; society and the planet does. Therefore, providing sustainability disclosures that are relevant to investors misses the point that sustainability disclosures are motivated by the desire of other stakeholders to learn about externalities. I discuss the different standard setters in the sustainability space and how accounting and measurement play key roles. I close with a discussion of research opportunities.
