Published: September 2023

AbstractThe present study aims to identify the most productive countries, journals, authors, institutions and the most used keywords in the field of special education during 2011–2020, based on the WoS database. The widespread effects of the papers and how they are related were analyzed with the bibliometric analysis method. The findings of the study showed that the USA is inarguably the most productive country, followed by England and Australia. On the other hand, there was a very strong positive correlation(r = 0.929) between the number of papers published by countries and their h-index, a similar finding was also found to be present between the countries' h-index and GDP per capita (r = 0.790). Moreover, it was found that the journals with the highest quartile (Q1 and Q2) in the field of special education published significantly more papers than the journals with the lowest quartile (Q3 and Q4). Matson, JL (USA), Sigafoos, J (New Zealand) and Lancioni, GE (Italy) were determined as the most prolific authors, respectively. Autism, intellectual disability, and Down syndrome were the phrases most frequently used as keywords. Our findings provide key information regarding the developments that the research direction of special education field has recently taken. This study also serves a potential roadmap for future studies.
Arms and the mollusc: An evolutionary arms race has produced armor based on molluscan biomineralization
Authors: Cartwright Julyan H. E. , Checa Antonio G. , Vendrasco Michael J. 
Published: September 2023

AbstractMore than half a billion years ago in the early Cambrian period, there began an evolutionary arms race between molluscs and their predators, in which molluscs developed armor in the form of a biomineral exoskeleton—a shell—to avoid being eaten by predators that were developing jaws and other novel means of devouring them. The mollusc fabricates multiple layers of shell, each of a particular microstructure of a composite between an inorganic and an organic phase, which are the end result of more than 500 million years of coevolution with increasingly deadly predators. Molluscan biomineralization is an excellent case to study how a biological process produces a complex structure, because the shell is constructed as an extracellular structure in which all construction materials are passed out of the cells to self-assemble outside the cell wall. We consider what is known of the development of multilayer composite armor in the form of nacre (mother of pearl) and the other strong microstructures with which molluscs construct their shells.

Nano-TiC-reinforced 18Ni300 steel manufactured by Powder Bed Fusion-Laser Beam with improved wear resistance for mould inserts
Authors: Ferreira Daniel F. S. , Miranda G. , Oliveira Filipe J. , Oliveira José M. 
Published: September 2023

AbstractIn injection moulding, surfaces can be exposed to harsh working conditions, especially when polymers reinforced with abrasive glass fibres are used. Low carbon martensitic steels, such as maraging steels, are an excellent choice for demanding and complex mould inserts produced by Powder Bed Fusion-Laser Beam (PBF-LB). However, their wear resistance is lower than that of tool steels such as AISI D2 or H13, whose PBF-LB printability is challenging, due to their carbon content that makes them susceptible to cracking. In this study, an alternative material with high printability by PBF-LB was developed, by reinforcing maraging steel 18Ni300 with nano-sized titanium carbide (TiC). TiC-reinforced 18Ni300 nanocomposites showed an improvement in microhardness of up to 23% (730 HV2) after addition of 7.0 vol% TiC. Tribological tests against a polypropylene with 40 wt% glass fibres showed that the specific wear rate decreased by about an order of magnitude (to 0.32 × 10–6 mm3/N m) compared to the unreinforced maraging steel.

Authors: Mahajan Lisa , Terzieva Liliya , Kaosol Waruth 
Published: September 2023

Background: The full potential of social entrepreneurship remains challenging to achieve, despite continuous efforts in various economies, including South-East Asia. Several obstacles need to be addressed, such as the scarcity of skilled employees, limited business understanding among founders, difficulties accessing funding and infrastructure, and the absence of proper social impact measurement. Higher education institutions (HEIs) often face constraints in engaging and supporting early entrepreneurial activities, exacerbating the imbalance in the social entrepreneurship landscape. This imbalance has been observed in both Thailand and Myanmar.
Research objectives: The Erasmus+ funded project, STEPup, running from 2020 to 2023, recognized an opportunity to foster innovative social entrepreneurship practices tailored for disruptive business settings in these two countries. By applying the challenge-based learning approach through interactive case challenge proceedings involving social entrepreneurs, faculty mentors and students, the development of the entrepreneurial mindset of the latter group was studied.
Research design and methods: To accomplish this, a multi-method research design was chosen, which involved a case-challenge experience within the framework of 6 universities, a questionnaire-based survey conducted among the student population which took part in the case-challenge experience and desk research.
Results: The study revealed the necessity for a self-organizing and organic support system for social entrepreneurship. The objective of this paper is to present recommendations and strategic guidelines to enhance access and opportunities for existing social enterprises and social entrepreneurs seeking to establish and sustain a social enterprise ecosystem. The proposed framework leverages the support, expertise, and structure of existing higher education institutions.
Conclusions: Higher Education Institutions can serve as excellent cases demonstrating how to design and develop resource hubs for social enterprise practitioners and engage stakeholders from all sectors to address social issues and promote awareness.

Published: September 2023

INTRODUÇÃO: Avaliar a importância do pré-natal durante o período gestacional, bem como identificar os riscos, benefícios e dificuldades desse acompanhamento na atenção básica. MÉTODO: Trata-se de uma revisão integrativa de literatura. O levantamento bibliográfico foi realizado no período de fevereiro a março de 2021, nas seguintes bases de dados: Scientific Eletronic Library Online (SCIELO) e Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS). Para operacionalizar a busca foram utilizados os seguintes descritores: “Atenção primária a saúde”; “Cuidado pré-natal”; “Enfermagem obstétrica” e ‘’Gestantes’’, em português. RESULTADOS: Foram analisados 13 artigos que atenderam aos critérios de inclusão. Os artigos foram ordenados em dois quadros de modo decrescente de acordo com ano de publicação. A partir da análise e síntese dos artigos incluídos foi possível delinear duas categorias, a saber: a importância do pré-natal e a promoção da saúde para a gestante. CONSIDERAÇÕES FINAIS: Conclui-se que o acompanhamento pré-natal com um profissional de saúde capacitado pode contribuir para a redução das complicações obstétricas e da morbimortalidade materno-infantil. A síntese dos resultados revela também que no contexto da atenção básica ainda não se realiza uma assistência pré-natal efetiva, pois existem lacunas na atenção básica.

Authors: Kanawala Arundati , Shekhawat Gulab Singh 
Published: September 2023

Background: Thyroid disorders are the predominant endocrinological afflictions of pregnancy that if were to affect the mother and her child, would lead to various complications.
Methods: A randomized study among 450 third trimester admitted cases for any indication were subjected to thyroid functions by TSH, Free T4 and TPO Ab. Total 61 mothers (54 hypothyroidism and 7 sub clinical hyperthyroidism) had thyroid dysfunction. These 54 hypothyroid mothers were further evaluated during the remaining course of gestation for feto-maternal outcomes.
Results: Out of 450 third trimester ANC cases 61(13.5%) had deranged thyroid functions in third trimester. Out of 61patients, 18 (29.50%) patients had TPO Ab positive. Prevalence of subclinical hypothyroidism, overt hypothyroidism, and subclinical hyperthyroidism was 9.6%, 2.45%, and 1.5%, respectively. Anemia was found in 9.3% of SCH and 27.3% cases in OH cases. Preeclampsia was found in 16.2% cases of SCH and 18.2% cases in OH cases. Gestational diabetes mellitus was noticed among 16.27% cases of SCH and 18.18% cases of OH. Previous abortions were present among 65.1% cases of SCH and 45.45% cases of OH. Placental abruption and cardiac failure were observed in 4.65% and 2.34% of SCH only. Cesarean delivery occurred in 18.6% of SCH and 36.36% of overt hypothyroidism.
Conclusions: This study concludes a high prevalence of thyroid disorders as subclinical hypothyroidism (9.6%), overt hypothyroidism (2.5%) and subclinical hyperthyroidism (1.5%) in third trimester pregnancy.

Authors: Pansari Nishtha , Diwan Arundhati , Rajbhoj Ashwin 
Published: September 2023

Background: Peripheral neuropathies are disorders of peripheral nerve cells and fibres. Chemotherapy-induced peripheral neuropathy (CIPN) is a common side effect of anticancer treatment, and it can affect the patient's long-term survival. The prevalence of CIPN is around 38%. Peripheral neurotoxicity (PN) is a side effect of paclitaxel that can lead to treatment discontinuation. The intensity and severity of neuropathy is more with patients receiving weekly paclitaxel chemotherapy.
Methods: 60 patients of CA breast receiving weekly paclitaxel monotherapy who fulfilled inclusion and exclusion criteria were enrolled in the study. Clinical examination and grading of neuropathy was done according to NCI-CTCAE version 4.0. All patient had undergone nerve-conduction studies at baseline and 3 months after baseline.
Results: 50% of patients, developed signs symptoms of peripheral neuropathy, out of which tingling sensation was the most common symptom (40%). The incidence of grade 1 peripheral neuropathy at 3 and 6 months were 35%, and 31.66%, while grade 2 neuropathy was noted in 18.33%, and 14.75% of patients, respectively. There was a significant difference in the SNAP value between baseline and 3 months for right ulnar nerve, right and left sural nerve and CMAP for right median nerve, right ulnar nerve, right and left tibial nerves which suggests development of neuropathy during 3 months of paclitaxel chemotherapy.
Conclusions: This study provides information on the incidence and severity of peripheral neuropathy in patients receiving weekly paclitaxel chemotherapy, which can help physician in further management.

Authors: Kumar Sanjay , Yadav Akhilesh 
Published: September 2023

Background: For skewed datasets, the mode is utilized as a more appropriate measure of location. We formed chain ratio and product estimators for the population mode using two types of auxiliary information under the two-phase sampling scheme.
Methods: Expressions for biases and mean square errors for the formed estimators up to the first order of approximation are obtained. The confidence intervals of the estimators are obtained and the aspects related to fixed cost and fixed variance are also studied. A simulation study is performed to support the theoretical outcomes. A real dataset is also provided which was collected from the department of agriculture, United States.
Results: The simulation results for the fixed first-phase sample size and the second-phase sample size show that the mean square error is 0.035, the bias is 0.012, the confidence interval is 2.67-3.15, and the cost of the survey under the fixed variance is ₹ 194.67 of the proposed estimator , which is lower than 0.039, 0.055, 2.70-3.20, and ₹ 247.37 of the ratio estimator and 0.078, 0.041, 2.57-3.31, and ₹ 268.73 of the naive estimator .
Conclusions: The simulation results show that the proposed estimator performs better than the ratio estimator and the naive estimator .

Os resultados indicam que, por meio da aplicação do protocolo IRDI e observação dos 31 indicadores de risco com vistas aos 4 eixos, torna-se possível estabelecer um roteiro de intervenções precoces quanto à prevenção. E ainda, sua aplicabilidade na área educacional possibilita que crianças e suas famílias tenham os devidos encaminhamentos para intervenções mais eficientes reduzindo os riscos de desenvolvimento infantil com prejuízos psíquicos.
Investigating the Impact of Aqueous Phase on CO2 Huff ‘n’ Puff in Tight Oil Reservoirs Using Nuclear Magnetic Resonance Technology: Stimulation Measures and Mechanisms
Authors: Liu Junrong , Li Hangyu , Liu Shuyang , Xu Jianchun , Wang Xiaopu , Tan Qizhi 
Published: September 2023

Summary
CO2 huff ‘n’ puff is a promising enhanced oil recovery (EOR) technique for tight/shale reservoirs, also enabling CO2 geological storage. However, the effectiveness of this method can be significantly affected by the aqueous phase resulting from connate water and hydraulic fracturing. The mechanism underlying the influence of the aqueous phase on oil recovery during CO2 huff ‘n’ puff, as well as the corresponding stimulation methods in such scenarios, remain unclear and warrant further study.
To investigate this, we utilized a nuclear magnetic resonance (NMR) instrument to track the movement of fluids during CO2 huff ‘n’ puff under water invasion conditions. The impact of the invaded aqueous phase on oil recovery was examined, and the impact of different treatment parameters was explored. The results show that the aqueous barrier formed by water invasion alters the pathway of CO2 diffusion to matrix oil. This alteration leads to a diminished concentration of CO2 in the oil phase, which, in turn, results in a substantial reduction in oil recovery. Consequently, the performance of CO2 huff ‘n’ puff is highly sensitive to the water phase.
Nevertheless, the oil recovery dynamics in cyclic CO2 huff ‘n’ puff under water invasion exhibit distinctive patterns compared with those without water invasion. These differences manifest as notable low oil recovery in the first cycle, followed by a rapid increase in the second cycle. This behavior primarily arises from the expulsion of a significant portion of the invaded water from the macropores after the first cycle. However, the effectiveness of this mechanism is limited in micropores due to the challenging displacement of trapped water in such pores. Raising the injection pressure mainly boosts oil recovery in macropores, with minimal response in micropores. Yet, the achievement of miscibility does not lead to a substantial improvement in the CO2 huff ‘n’ puff performance, primarily due to the constraints imposed by the limited CO2 dissolution through molecular diffusion
Additionally, we have proposed three stimulation mechanisms achieved by lengthening the soaking time under water invasion conditions. First, the prolonged soaking time increases the concentration of CO2 molecules that diffuse into the matrix oil. Second, it promotes the imbibition of the trapped water on the fracture surface into the deeper matrix to alleviate water blockage. Finally, the invaded water in macropores displaces oil in micropores by capillary force during the soaking period.

Abstract

The standard method for identifying active Brown Adipose Tissue (BAT) is [18F]-Fluorodeoxyglucose ([18F]-FDG) PET/CT imaging, which is costly and exposes patients to radiation, making it impractical for population studies. These issues can be addressed with computational methods that predict [18F]-FDG uptake by BAT from CT; earlier population studies pave the way for developing such methods by showing some correlation between the Hounsfield Unit (HU) of BAT in CT and the corresponding [18F]-FDG uptake in PET. In this study, we propose training convolutional neural networks (CNNs) to predict [18F]-FDG uptake by BAT from unenhanced CT scans in the restricted regions which are likely to contain BAT. We performed experiments on datasets from four different cohorts, the largest study to date. We segmented the BAT regions using the predicted [18F]-FDG uptake values and evaluated the accuracy of the segmentations, showing 23% to 40% improvement over the conventional CT thresholding-based method. Additionally, we showed that BAT volumes computed from the segmentations could be used to distinguish subjects with and without active BAT with an AUC of 0.8, whereas the CT thresholding-based method achieved 0.6. Our findings suggest that CNNs, when trained on cold-stimulated cohorts, can be effectively used to create stratified cohorts from only CT, thereby having the potential for facilitating large-scale imaging studies with greater efficiency and lower costs.
Plasma Powder Transferred Arc Additive Manufacturing of ((Fe,Ni)-Al) intermetallic alloy and resulting properties
Authors: Treutler Kai 
Published: September 2023

Abstract
Intermetallic alloys such as iron aluminides are of increasing interest for high temperature applications due to their properties. However, their application potential is limited by their limited machinability with conventional manufacturing methods such as milling. Arc-based additive manufacturing offers an approach to produce these materials to final contour or with very little post-processing. However, the properties of many intermetallic alloys, such as low toughness, require a special manufacturing process. Using a selected iron-nickel-aluminum intermetallic compound as an example, a possible process, including a subsidiary heat treatment, for the arc-based additive manufacturing of materials based on brittle intermetallic materials is presented, which could enable the production of structural components. In addition, some basic mechanical properties that can be achieved in a component are shown proportionally. These properties include initial investigations into the wear resistance of these compounds. It is shown that these intermetallic compounds have a superior wear resistance as commonly used co-base alloys, but have a lower density compared to these co-alloys.
