Background:

Although rare, cases of hypophysitis resembling a pituitary abscess (PA) have been reported. Differential diagnosis between hypophysitis and PA is crucial as the two diseases require different treatments.

Case Description:

A 38-year-old woman with headaches underwent head magnetic resonance imaging (MRI), which revealed an 11-mm mass lesion in the sella turcica. Due to breastfeeding, contrast-enhanced MRI was avoided. Pituitary adenomas and Rathke’s cleft cyst (RCC) were suspected, and she was initially treated conservatively. Five months later, she acquired syndrome coronavirus two infections, and while the fever subsided with acetaminophen, the headache persisted. One month later, the headache worsened, followed by fever and diabetes insipidus. MRI revealed a pituitary cystic mass with ring-shaped contrast enhancement on T1-weighted MRI and increased signal intensity on diffusion-weighted imaging (DWI). PA was suspected, and emergency endoscopic transsphenoidal surgery was performed. The microbiological examination of the yellowish-brown content drained from the cystic mass was negative. Microscopically, the cystic lesion was covered with ciliated columnar epithelium and stratified squamous epithelium, with a dense inflammatory cell infiltrate consisting mainly of lymphocytes and plasma cells observed around the cyst. This supported the diagnosis of secondary hypophysitis associated with RCC without PA.

Conclusion:

We report a case of hypophysitis secondary to RCC resembling PA with ring-shaped contrast enhancement on MRI and increased signal intensity on DWI. This case emphasizes the need for cautious diagnosis of secondary hypophysitis due to RCC in individuals with MRIs and clinical manifestations resembling an abscess.
Doping Implications of Li Solid State Electrolyte Li7La3Zr2O12
Authors: Eggestad Kristoffer , Selbach Sverre , Williamson Benjamin
Published: March 2024

Solid-state electrolytes, like Li7La3Zr2O12 (LLZO), can enable safer, more energy dense and longer lasting batteries. However, there are still challenges concerning dendrite formation and poor Li-ion conductivity. Here we investigate the effect of Al, Ga, Nb, Ta, and Y doping of LLZO using hybrid density functional theory calculations. The inferred site preferences of Al, Ga, Nb, and Ta result in donor defects that stabilise additional Li vacancies. More Li vacancies lead to increased disorder on the Li sublattice, thus predicting a stabilisation of the more ionic conducting cubic phase. Furthermore, our calculations indicate that the effect of the dopants on the sintering process is even more important than the ability to induce more ionic charge carriers. Finally, differences in Li vacancy formation energies suggest a new possible explanation for the two orders of magnitude increase in ionic conductivity upon stabilising the cubic phase.

Published: March 2024

Multiple dividing wall columns are a promising extension of the concept of dividing wall columns offering energy savings of up to 55 % compared to conventional distillation sequences for four products. This paper presents the first systematic study on the start-up of a multiple dividing wall column. The study aims to develop a start-up strategy for the first pilot multiple dividing wall column worldwide commissioned at Ulm University. The start-up process is investigated using a dynamic simulation model that facilitates the investigation of different start-up strategies and the influence of different factors on the start-up process. Based on these dynamic simulations a viable start-up procedure for the column is found. Through improvements to the procedure a significantly shortened start-up process is achieved. The dynamic response of the column shows that the cold and dry plant is able to reach the desired operating point within few hours. Simulation results are confirmed with experimental data from the pilot column.
Hole-Selective Hybrid TiO2 Layer towards Long-Term Stability of Low-Cost Photoanodes in Solar Water Oxidation

Published: March 2024

The use of conductive and corrosion-resistant protective layers represents a key strategy for improving the durability of light absorber materials in photoelectrochemical water splitting. For high performance photoanodes such as Si, GaAs, and GaP, amorphous TiO2 (a-TiO2) protective overlayers, deposited by atomic layer deposition, are conductive for holes via a defect band in the TiO2. However, when coated on simply prepared, low-cost photoanodes such as metal oxides, no charge transfer is observed through a-TiO2. Here, we report a hybrid polyethyleneimine (PEI)/TiO2 layer that facilitates hole transfer from model oxides BiVO4 and Fe2O3, enabling access to a broader scope of available materials for practical water oxidation. A thin PEI layer between the light absorber and the hybrid PEI/TiO2 acts as a hole-selective interface, improving the optoelectronic properties of the photoanode devices. These PEI/TiO2 modified photoanodes exhibit high photostability for solar water oxidation (~2 mA cm-2 for > 120 h).

Published: March 2024

The signature structure of collagen, the triple helix, comprises three collagen strands with GlyXaaYaa repeats intertwining into a right-handed superhelix. Pro and Hyp at the respective Xaa and Yaa positions provides maximum triple helical stability. Previously, we reported that peptoid residues also known as N-substituted Glycines (N-Glys) in the Xaa position generate hyperstable collagen triple helices. Here, we demonstrate that N-Glys at the Yaa position also stabilize the triple helix, with the position (Xaa or Yaa) and side chain structure of N-Gly profoundly affecting the triple helix stability. CD spectroscopy and X-ray crystallography indicated that N-Glys at the Yaa position were more conducive to triple helical folding than amino acids, although they were unable to access the most favorable phi-psi angles for the triple helix represented by Hyp. Metadynamics simulations showed a more diffused conformational space for N-Glys at the Yaa position than at the Xaa position due to minimal steric crowding from neighboring Gly. Only the S-isomers of chiral N-C(alpha) branched N-Glys were compatible with triple helical folding, with differences in backbone conformation and accessible rotamers between Xaa and Yaa positions. At the Yaa position, chiral Nspe can stabilize the triple helix better than any other natural or unnatural residues (except Hyp) via the intrachain CH•••Pi interactions. This work not only deepens our understanding of triple helical folding but also demonstrates a new design strategy for stable collagen mimetic peptides with unprecedented side chain diversity, opening new opportunities for applications in biomedicine and biomaterials.
Mass spectrometric evidence for the underrepresented RNA-protein crosslinks
Authors: Bae Jong Woo
Published: March 2024

In protein-RNA complexes, UVC crosslinks proteins predominantly to uracil. Concrete evidence for other UVC-crosslinked RNA bases is lacking. Here, I elucidate mass spectrometric signatures of UVC-crosslinked guanine, cytidine, and methyladenine. This can help us capture the native protein-RNA interactions in more detail.

Published: March 2024

Background

Vaccination adherence among healthcare workers (HCWs) is fundamental for the prevention of vaccine-preventable diseases (VPDs) in healthcare. This safeguards HCWs' well-being, prevents transmission of infections to vulnerable patients and contributes to public health.

Aim

This systematic review and meta-analysis aimed to describe interventions meant to increase HCWs’ adherence to vaccination and estimate the effectiveness of these interventions.

Methods

We searched literature in eight databases and performed manual searches in relevant journals and the reference lists of retrieved articles. The study population included any HCW with potential occupational exposure to VPDs. We included experimental and quasi-experimental studies presenting interventions aimed at increasing HCWs’ adherence to vaccination against VPDs. The post-intervention vaccination adherence rate was set as the main outcome. We included the effect of interventions in the random-effects and subgroup meta-analyses.

Results

The systematic review considered 48 studies on influenza and Tdap vaccination from database and manual searches, and 43 were meta-analysed. A statistically significant, positive effect was seen in multi-component interventions in randomised controlled trials (relative risk (RR) = 1.37; 95% CI: 1.13–1.66) and in observational studies (RR = 1.43; 95% CI: 1.29–1.58). Vaccination adherence rate was higher in community care facilities (RR = 1.58; 95% CI: 1.49–1.68) than in hospitals (RR = 1.24; 95% CI: 0.76-2.05).

Conclusion

Interventions aimed at increasing HCWs’ adherence to vaccination against VPDs are effective, especially multi-component ones. Future research should determine the most effective framework of interventions for each setting, using appropriate study design for their evaluation, and should compare intervention components to understand their contribution to the effectiveness.
Burden of chickenpox complications in Poland, 2006 to 2021: A comprehensive registry-based study
Authors: Halik Rafał , Paradowska-Stankiewicz Iwona , Trochonowicz Aneta , Dittmer Swavik
Published: March 2024

Background

Chickenpox, a vaccine-preventable disease caused by the varicella zoster virus, generally presents with mild symptoms but can cause complications necessitating hospitalisation. In Poland, since 2009, vaccination has been obligatory for children up to 12 years of age who are particularly vulnerable to infection and for children in their vicinity.

Aim

To examine the burden of chickenpox complications and the trends of hospitalisation arising from these complications over time in the Polish population.

Methods

Data spanning 2006–21 were sourced from the Polish Infectious Diseases Surveillance System, the Nationwide General Hospital Morbidity Study and the Statistics Poland death registry. Standardised and age-specific incidence rates, hospital discharge rates and number of deaths because of chickenpox were calculated. Moreover, the joinpoint regression model was used to analyse trends of annual hospital discharge rates.

Results

Over the analysed timeframe, 25,804 hospitalisations and 52 deaths attributable to chickenpox complications were documented, and 1.0% of chickenpox cases required hospitalisation because of chickenpox. Age-standardised hospitalisation rates varied between 2.3 and 9.6 per 100,000 population. The analysis revealed no statistically significant trend in overall hospital discharge rates from chickenpox complications. However, a notable increase in hospitalisation rates was observed in children aged 0–4 and among inhabitants of rural areas, with annual percentage changes of 4.9% and 3.4% respectively.

Conclusions

Our findings suggest that the implementation of a universal chickenpox immunisation programme, supported by health education, should be considered to reduce the number of hospitalisations and nearly eliminate deaths because of chickenpox.

The Norm of Marriage Age Limit and Cultural Contestation of Child Marriage Law in Rural Communities
Authors: Syahrudin Hidayat  , Abdul Ghofur  , Ummul Baroroh
Published: March 2024

Changes in state legal norms regarding the age limit for marriage have been implemented to reduce the number of child marriages in Indonesia. However, child marriage is still practised, especially in rural areas of Central Java. This paper discusses three main problems, namely the prevalence of child marriage in rural areas, the dominance of tradition and dogmatic understanding of religion, the impact of poverty and social media technology as factors influencing child marriage in rural communities, and the transformation of social engineering through education and economic improvement to overcome the problem. child marriage in rural areas. This legal sociology research uses a qualitative approach.  Data analysis techniques use interactive models. The study shows that the prevalence of child marriage increased by 300% after changes in norms regarding the age limit for marriage, especially in rural communities. This happens because child marriage in rural communities is a tradition passed down through generations. Traditions and religious norms understood by rural communities as allowing child marriage have become an unwritten legal system implemented by the community. Changes in state legal norms regarding marriage age limits have the potential to disrupt established social institutions, so that sociologically they are not binding as norms for rural communities, giving rise to an apathetic public response. Therefore, efforts to improve the education and economic systems with a holistic approach are very effective in overcoming the problem of child marriage in rural communities.

Published: March 2024

The number of disputes in religious courts continues to increase every year, giving great potential to develop the use of artificial intelligence to make it more efficient and effective by paying attention to the basic principles of Islamic law. This paper discusses the potential and development of the use of artificial intelligence technology in dispute cases in religious courts based on Maslahah Mursalah. The research method is juridical-normative, with a conceptual and philosophical approach. The research shows that the use of artificial intelligence in dispute resolution at religious courts is important for the reason that it can minimize the risk of errors and help judges determine legal considerations in the dispute resolution of Islamic law so that they are more accurate, effective, and efficient. The potential for developing the use of artificial intelligence technology in religious courts must consider several aspects, including the integration of artificial intelligence technology in the dispute resolution process in religious courts, the development of artificial intelligence-based decision support systems, and legal-ethical aspects of the use of artificial intelligence in religious courts. The formulation of the concept for developing the use of artificial intelligence technology in dispute resolution in the religious courts must be guided by the Maslahah Mursalah principle as a moral-ethical foundation within the legal system framework, which includes legal structure, legal substance, and legal culture so that the development of the use of artificial intelligence technology in the disputes resolution of Islamic law in religious courts be effective and justice for all.
Epistemology of Fatwas on Digital Transaction in Indonesia
Authors: Bashori Akmal , Mutho'am Mutho'am , Noor Hazlina Wan Jusoh Wan
Published: March 2024

The shift from conventional business transactions to digital business transactions, especially for the Muslim community in Indonesia,  necessitates a fast and reactive response from current laws. The theoretical argument that has been developed thus far is that the fatwa is the most appropriate legal tool for Muslim communities to respond to the rapid development of digital business. Nevertheless, do the existing fatwas fulfill legal needs as expected in this era of digital transactions? Hence, this paper discusses digital transaction fatwas within the framework of Islamic legal epistemology, especially fatwas from the National Shariah Council–Indonesian Ulama Council. The research method uses normative juridical with a conceptual and historical-uṣūliyah approach. This research finds that the contemporary fatwa epistemology of the National Shariah Council–Indonesian Ulama Council in terms of digital transactions employs istiṣlāhī arguments. This is shown by the proposition that fiqh rules are more dominant than textual ones. Moreover, the arguments in the fatwa of the National Shariah Council–Indonesian Ulama Council provide signs of benefit as the estuary of maqāṣid syarī'ah. The consistency of the use of legal methodology utilized by the National Shariah Council–Indonesian Ulama Council in fatwas on digital transactions is shown in the structure and utilization of al-nuṣūṣ al-shariah arguments, the opinions of ulama, and the rules of fiqh, which are expanded from the five rules of fiqh into eight rules. These fatwas are reliable and valid in terms of dictum and method, thus supporting the development of the current digital transactions.
Inappropriate Behavior in Buying and Selling Usernames on Twitter: An Islamic Law Perspective
Authors: Nizami Auliya Ghazna , Andini Rahma Hidayah  , Hidayatulloh
Published: March 2024

Transformations in the digital world allow illicit transactions such as buying and selling usernames, which are currently popular among social media users, especially on Twitter. The more people who use Twitter, the more usernames are used, and the system will automatically reject new user requests with usernames that have already been used. This research examined username buying and selling transactions and inappropriate behavior by users on Twitter. This research used qualitative methods with an approach to Islamic legal norms. Data were obtained from document studies and interviews with sellers and buyers of usernames via Twitter direct messages. The results of the research showed that buying and selling usernames are an illegal and prohibited sale because many inappropriate behaviors, such as hacking, are found, resulting in nonfulfillment of the conditions for the objects bought and sold. Islamic law stipulates that traded objects must meet requirements such as perfect ownership, clear, useful, and halal. This means that there is no element of gharar in every buying and selling transaction because it can cause disputes between the seller and the buyer.

Published: March 2024

In this paper, we present a new four-step iterative scheme namely DH-iterative which is faster than many super algorithms in the literature for numerical reckoning fixed points. Under this algorithm, some fixed point convergence results and ω 2 -stability for contractive-like and Reich-Suzuki-type nonexpansive mappings are proposed. Our results extend and improve several related results in the literature. Finally, some numerical examples are given to study the efficiency and effectiveness of our iterative method.
Investigating the Relationship between University Environment and Female Student’s Entrepreneurial Thinking in Algeria
Authors: Saadaoui Atmane , Mohamad Armanurah , Abd Rani Shamsul Huda
Published: March 2024

Female entrepreneurship is a growing segment which has the potential to promote economic growth and job creation in specific regions and countries. In particular, there is no consensus on the most effective way to foster female entrepreneurship. Universities are well-known actors where female students' entrepreneurial thinking can be developed. Moreover, the educational policies related to supporting students’ entrepreneurial activities differ significantly among institutions and environments. Based on the lens of institutional theory, the aim of this study is to analyze the influences of the university environment on the development of entrepreneurial thinking among Algerian female university students. A self-administered survey was used in this study to gather data from 413 female students enrolled in three different Algerian universities. Using Smart-PLS software, the outcomes assert that the normative and cognitive dimensions significantly influence entrepreneurial thinking among female business students in Algerian universities. Such a finding contradicts past research on the impact of the regulative dimension and brings fresh insights into the role of the support of Algerian higher education institutions in fostering the entrepreneurial thinking of their female business students.
A presença/ausência da bruxa nos contos de fadas de Marina Colasanti
Authors: Ferreira da Silva Edilane
Published: March 2024

Os contos de fadas de Marina Colasanti representam princesas, príncipes, reis, entre outras/os personagens-tipo do contexto medieval, com exceção da controversa bruxa. Há apenas a construção de uma feiticeira, no conto “Quem me deu foi a manhã” (2009), a qual é condenada à morte na fogueira por acusação de praticar bruxaria. Em “Entre as folhas do verde O” (1979), “Debaixo da pele, a lua” (1997), “Vermelho, entre os troncos” (2009) e “São os cabelos das mulheres” (2009), as protagonistas se metamorfoseiam em lua e loba. Nos contos, essas personagens se conectam à natureza mais-que-humana e a uma natureza instintual ou selvagem, isto é, ao feminino arquetípico, e é por intermédio dessas inter-relações que elas resistem às violências patriarcais. Tais produções são lidas a partir de uma perspectiva ecofeminista, com base nas contribuições teóricas de Mies e Shiva (1993), Starhawk (1989), entre outras. Argumento que essas protagonistas, ao serem mimetizadas como mulheres conhecedoras e conectadas a elementos da natureza, são, na realidade, representações da bruxa, mas não conforme o estereótipo dos contos clássicos. Elas se vinculam às mulheres que foram consideradas bruxas e queimadas pela Inquisição. Colasanti, portanto, ainda que não categorize as personagens como bruxas, promove uma revisão da representação da bruxa nos seus contos de fadas contemporâneos e revisionistas.

Mapeamento da cadeia produtiva do feijão-comum no Brasil
Authors: Oliveira Gilmara Martins de , Wander Alcido Elenor
Published: March 2024

O Brasil está entre os maiores produtores, consumidores e importadores mundiais de feijão. O feijão possui grande importância econômica e nutricional para a população, é a principal fonte de proteína vegetal consumida pelo brasileiro. O objetivo deste trabalho foi fazer o mapeamento da cadeia produtiva do feijão no Brasil, procurando entender as relações entre os agentes presentes em cada elo. Buscou-se analisar o funcionamento da cadeia produtiva e os principais entraves que têm afetado a competitividade. Por meio de pesquisa bibliográfica e análise de dados disponibilizados por entidades relacionadas ao setor obteve-se informações que permitiram a descrição da cadeia produtiva e suas principais características. Assim, tem-se que a cadeia em questão está geograficamente dispersa, em praticamente todos os estados brasileiros há produção de feijão. Apresenta baixo nível organizacional, o que aumenta os custos transacionais; baixa capacitação técnica por parte dos produtores e custos produtivos elevados com defensivos e fertilizantes devido à alta incidência de pragas e doenças.
Uma análise estrutural do desenvolvimento e do emprego no estado de Alagoas no período de 2004-2014
Authors: Da Silva Karine Daniele
Published: March 2024

O presente estudo teve como objetivo analisar a maneira como o desenvolvimento econômico determina o perfil do emprego gerado, tomando o estado de Alagoas como estudo de caso. Ao realizar a análise para o período de 2004 a 2014, percebe-se que a estrutura ocupacional resultante das vagas criadas é precária e seletiva, pois em sua maioria demandaram trabalhadores do sexo masculino, com segundo grau completo, idade entre 18 e 24 anos, com rendimentos de no máximo um salário mínimo e meio, ocupados no setor de serviços e comércio, em empresas de micro porte. Com base no resultado da análise dos dados, conclui-se que o foco em atividades produtivas com pouco conteúdo tecnológico, como o caso do setor de serviços, em Alagoas, acaba gerando empregos precarizados e com baixas remunerações, muitas vezes por exigir uma mão de obra pouco qualificada. Nesse sentido, gera-se um ciclo vicioso que impede o ganho de riqueza e, consequentemente, o desenvolvimento local sustentado.

Published: March 2024

Ветровые воздействия способны существенно влиять на конструктивную прочность и устойчивость зданий и сооружений. Объекты с большим фронтальным сечением испытывают большое лобовое сопротивление, поэтому воздействие ветра вносит значительный вклад в динамическую нагрузку на конструкцию и может привести к потере ее устойчивости и разрушению. Ветровая нагрузка на сооружение зависит от характеристик ветра, параметров конструкции и аэродинамических коэффициентов. Целью настоящей работы является экспериментальное определение аэродинамических коэффициентов для различных групп резервуаров вертикальных стальных для хранения нефти и нефтепродуктов. Исследования проводились на масштабных моделях резервуаров в специализированной аэродинамической трубе для испытаний зданий и сооружений. Полученные по результатам эксперимента данные сравнивались с результатами расчета ветровых нагрузок по нормативным методикам. Также в рамках эксперимента была выполнена визуализация структуры ветрового потока классическим дымовым методом. Полученные изображения структуры потока хорошо согласуются с базовыми представлениями аэрогидродинамики об обтекании цилиндрических тел ветровым потоком. Установленные по результатам исследований значения аэродинамических коэффициентов для испытанных компоновок резервуаров позволяют определять ветровую нагрузку на поверхности исследуемого объекта, задавая значения нормативного ветрового давления и коэффициента надежности в соответствии с нормативными требованиями и не влияют на увеличение металлоемкости резервуарных конструкций.

Wind impacts can significantly affect the structural strength and stability of buildings and structures. Wind load on a structure depends on the wind characteristics, design parameters and aerodynamic coefficients. The purpose of this work is the experimental determination of aerodynamic coefficients for various groups of vertical steel tanks used for storage of oil and oil products. The studies were carried out on scale models of tanks in a specialized wind tunnel used for testing buildings and structures. The data obtained from the results of the experiment were compared with the results of calculating wind loads according to standard methods. Also, as part of the experiment, the visualization of the structure of the wind flow was performed using the classic smoke method. The obtained images of the wind flow structure are in good agreement with the basic concepts of aerodynamics about wind flow flowing around cylindrical bodies. The values of aerodynamic coefficients established based on the results of the studies for the tested tank layouts allow determining the wind load on the surface of the object under study by setting the values of the standard wind pressure and the reliability coefficient in accordance with the regulatory requirements.

Authors: Febriadi Sandy Rizki , Kurniawan Cecep Soleh
Published: March 2024

Indonesia is a country with the largest muslim population in the world. Muslim population in Indonesia is 80% of the approximately 220 million Indonesian population. That is, about 180 million Muslims have the obligation to pay zakat, both zakat fitrah and zakat assets. This condition should be an extraordinary zakat potential related to zakat collection efforts. However, the development of zakat management institutions has not been accompanied by the growth of public interest in paying zakat to these zakat institutions. The impact is that the management of zakat in Indonesia is not optimal, while the potential for zakat in Indonesia is very large. This research purposes to find out concept of zakat, history, legal basis, types, and its wisdom. As well as, it describes legal regulations of zakat, laws and other regulations that applied in Indonesia, especially related to the institutional aspects of zakat institutions. The research method used is a normative juridical approach, which is a method of researching a thought related to the laws that apply in society. The research result implied that Zakat is the name for a certain property, obtained from a certain property, according to a certain way and given to a certain group of people as well. Legally, the development of zakat management regulations in Indonesia began with the issuance of Law Number 23 of 2011 concerning Zakat Management, until the issuance of the Decree of the Chairman of BAZNAS Number 142 of 2017 concerning the Nishab Value of Zakat for Income in 2017.
