Authors: Ghellab Torkia , Charifi Zoulikha , Baaziz Hakim , Latelli Nadjia
Published: December 2023

The current study focused on examining the structural, mechanical, and optoelectronic properties of CuF, CuCl, CuBr, and CuI by the utilisation of the FP-LAPW method. The calculations reveal that GGA is a better fit than LDA for evaluating structural characteristics, including lattice parameters and bulk modulus. The examination of the band structure reveals that CuF exhibits metallic behaviour, whilst the compounds CuCl, CuBr, and CuI exhibit semiconducting properties, characterised by direct fundamental gaps (Γ → Γ) of 0.516, 0.425, and 1.049 eV, respectively. The peak absorption values for CuCl, CuBr, and CuI are located at 10.68 eV, 9.53 eV, and 7.68 eV, respectively. All materials have ultraviolet absorption peaks. Therefore, the compounds demonstrate substantial absorption in the low- and mid-ultraviolet wavelengths. The four compounds exhibit anisotropic properties, possess ductility, and demonstrate mechanical stability. These entities possess the ability to endure a wide range of temperatures. The thermoelectric performance of the three semiconductors, CuCl, CuBr, and CuI, was investigated. At 300 K, the k

L
values for CuBr, CuCl, and CuI, are 2.89 W/mK, 3.98 W/mK, and 3.56 W/mK, and the Gruneisen values are as follows: γ (CuCl) = 2.4087, γ (CuBr) = 2.4747, and γ (CuI) = 2.1962. At a temperature of 600 K, the k

T
value is found to be relatively low. The measured values for the k

T
of CuCl, CuBr, and CuI are around 1.7818 W m−1 K−1, 1.5109 W m−1 K−1, and 2.8580 W m−1 K−1, respectively. At a temperature of 300 K, the Seebeck coefficients (S) for CuCl, CuBr, and CuI are measured to be 1192.7964 μV/K, 1170.5882 μV/K, and −65.7454 μV/K, respectively. At a temperature of 800 K, the p-type compound CuBr exhibits a maximum figure of merit (ZT) value of 0.6691, corresponding to a charge carrier concentration of 31.7926 × 1020 cm3. The CuCl and CuI compounds exhibit the maximum ZT values of 0.52043 and 0.5609, respectively. In order to achieve the desired results, it is necessary to decrease the charge carrier concentration in CuCl to n = 0.514 × 1022 cm−3 and increase the charge carrier concentration in CuI to n = 9.686 × 1022 cm−3; alternatively, the chemical potentials should be decreased by 0.2563 Ryd and 0.3974 Ryd, respectively.
Occupational health in a post-pandemic world of work. Introduction to this special issue
Authors: Dörflinger Nadja , Tisch Anita
Published: December 2023

Although occupational safety and health (OSH) is a core element of social policy, OSH had rarely been in the focus of social policy research in the years preceding the Covid-19 pandemic. Therefore, this special issue brings together state-of-the-art theoretical and empirical insights underlining the connection between OSH and social policy. It contains articles from different academic disciplines dealing with the following broad topics: actors and institutions involved in OSH, OSH policies and measures, and social inequalities related to OSH. The special issue makes three contributions. First, it puts a traditional and highly relevant but under-researched topic back in the focus of attention. Second, it revives the debate by providing interdisciplinary insights on a number of key topics of relevance. Third, these insights have strong implications for policymaking; they are thus of high practical relevance and could contribute to enhancing the protection of workers in the post-pandemic labour market.
Béke minden áron

Oroszország 2022-ben indult Ukrajna elleni támadása kihívás elé állította az alapvetően orosz-párti és ukránellenes magyar kormányzati politikát. A háború előtt a magyar kormány a romlatlan Kelet és a hanyatló Nyugat diskurzusát alkalmazta. Feltételezésem szerint ez a keretezés továbbra is a magyar kormány külpolitikai diskurzusának az alapját képezi, mivel a kormányzati kommunikáció a korábbi nyugatellenes diskurzusába beillesztette az orosz-ukrán háború nyomán kibontakozó válságot. Ugyanígy az orbáni magyar külpolitika korábban alkalmazott és hangoztatott elveinek (szuverenitás és nemzeti érdek védelme, pragmatizmus, kölcsönös tisztelet, költséghaszonelv) a kontinuitásáról beszélhetünk.
Új fogyasztói szokások a vendéglátásban
Authors: Pókó Nikolett
Published: December 2023

Ahogy a turizmus úgy a vendéglátás is egy dinamikusan fejlődő ágazat. A napjainkban végbemenő gazdasági, technológia, környezeti, társadalmi változásokra reagálnia kell a vállalkozásoknak is. Érzékelhető, hogy új fogyasztói szokások alakulnak az 21. századi ember életviteléhez igazodva. A fogyasztói döntéshozatal vendéglátásra gyakorolt hatása nagyon meghatározó. A folyamat mindkét oldalát vizsgálni kell, a fogyasztók oldalát éppen úgy mint a szolgáltatók oldalát.  Napjainkban, a válságok megjelenésével egyre fontosabbá válik az, hogy a vásárlókat a gyártók és az értékesítők valamilyen formában magukhoz kössék, megnyerjék. Ennek érdekében a márka mellett valamilyen hozzáadott tényező szükséges a vásárlói lojalitás kialakítására. A fogyasztó döntését azonban nemcsak az egyén csoportban betöltött szerepe határozza meg, hanem azon belső tulajdonságok összessége is, melyek a fogyasztó ízlését, fogyasztói attitűdjét alakítják. A fogyasztást befolyásoló tényezők azonosítása lehetővé teszi a megfelelő marketingkommunikációs stratégia kialakítását az ágazati szereplők és szolgáltatók számára.
Eyes of the machine: AI-assisted satellite archaeological survey in the Andes
Authors: Zimmer-Dauphinee James , VanValkenburgh Parker , Wernke Steven A.
Published: December 2023

Archaeological surveys conducted through the inspection of high-resolution satellite imagery promise to transform how archaeologists conduct large-scale regional and supra-regional research. However, conducting manual surveys of satellite imagery is labour- and time-intensive, and low target prevalence substantially increases the likelihood of miss-errors (false negatives). In this article, the authors compare the results of an imagery survey conducted using artificial intelligence computer vision techniques (Convolutional Neural Networks) to a survey conducted manually by a team of experts through the Geo-PACHA platform (for further details of the project, see Wernke et al. 2023). Results suggest that future surveys may benefit from a hybrid approach—combining manual and automated methods—to conduct an AI-assisted survey and improve data completeness and robustness.
Migration and ethnicity in prehistoric and early historic Europe
Authors: Cavazzuti Claudio
Published: December 2023

I am very grateful to Antiquity for asking me to read and write a review article of these two volumes. Together they provide an integrated picture of trends in recent years on the themes of mobility and ethnicity in late prehistoric and early historic Europe. Topics, chronology and regional focus are different, if not often opposed, in each book but the reader can easily catch the common ground for further reflection.
Contexte organisationnel de projet et production de santé psychosociologique : exploration pragmatiste
Authors: Djoudi Farida , Bredillet Christophe
Published: December 2023

La santé psychosociologique est un enjeu de première importance notamment en contexte de projectification. Ainsi le lien entre santé psychosociologique et gestion de projet doit être repensé au-delà des modèles traditionnels. L’article propose une réflexion théorique sur ce lien peu exploré. Pour appuyer cette réflexion, nous proposons une intégration, selon une perspective pragmatiste, des deux domaines théoriques conduisant à définir trois propositions exprimant la relation réflexive entre pratiques organisationnelles en gestion de projet, performance psychosociale et santé psychosociologique. Les implications pour la gestion de projet et un agenda de recherche concluent notre contribution.
mise en œuvre de l’IA dans les organisations est-elle compatible avec une société éthique?
Authors: Tremblay Diane-Gabrielle , Psyché Valérie , Yagoubi Amina
Published: December 2023

Cet article expose les compétences essentielles à la gestion de l’intelligence artificielle (IA) dans les organisations en mettant l’accent sur la dimension éthique, mais sans négliger les enjeux d’un point de vue managérial, technique, humain, inclusif et responsable. En effet, dans le contexte de changement associé à la transformation numérique, les organisations qui se numérisent, en intégrant l’IA, ont besoin d’identifier les enjeux éthiques et les compétences requises associées pour gérer des projets d’IA. Les enjeux liés au développement et à la gestion des projets d’IA sont complexes et différents de ceux liés à la gestion traditionnelle des projets informatiques. Cette complexité soulève des questions éthiques, juridiques et de responsabilité sociale (du point de vue de l’équité, de la diversité et de l’inclusion) en matière d’IA; celles-ci auront des implications sur les compétences attendues des gestionnaires de projets d’IA à l’avenir. Notre recherche visait à identifier ces enjeux et à les décrire en matière de compétences, ce que nous avons fait au moyen d’entrevues et de groupes de discussion avec des experts de la communauté de l’IA, dans le contexte plus large d’une recherche sur la gestion de l’IA. Cet article porte surtout sur les enjeux éthiques dégagés de notre revue des écrits et des rencontres avec des experts de l’IA et leur résonance dans l’écosystème d’IA québécois; nous nous concentrons donc ici sur les questions d’éthique, de transformation du marché du travail, de gouvernance et de responsabilité sociale.
« Star Model » pour analyser et articuler un changement organisationnel
Authors: Brunet Maude
Published: December 2023

Cet article présente le « Star Model » couramment mobilisé en stratégie (Kates et Galbraith, 2007), et plus récemment en gestion de projet, afin d’analyser une entité organisationnelle gérant des projets (organisation, direction ou bureau de projet). Les piliers de ce modèle en étoile sont les capacités organisationnelles, les talents, le système de récompense, les processus et la structure. Un exemple inspiré d’un cas réel permet de faire une analyse sommaire d’une organisation en milieu événementiel, et d’utiliser une grille d’analyse pour proposer un plan d’action afin d’opérer les changements organisationnels permettant une gestion de projet plus adaptée à l’organisation et à son contexte.
Les principales contributions de l’article sont d’ordre théorique, avec pour objectif de faire ressortir l’importance des interrelations à la limite des champs disciplinaires de la gestion de projet, de la stratégie et de la gestion de changement. Il a aussi des visées pratiques, comme le modèle et la grille d’analyse sont des outils réflexifs pouvant être utilisés par des gestionnaires ou analystes dans divers contextes organisationnels.
Communist Legacy, Anti-Elite Sentiments, and Modernization Theory
Authors: Vasilyeva Olga , Libman Alexander
Published: December 2023

Communist rule left a strong imprint on the development of Eastern European countries, but the precise mechanisms and directions of this legacy effect are subject to debate. This article looks at the legacies of giant infrastructural projects, which played an important role in the ideology and policy practice of communist regimes. Using the natural experiment of the Baikal-Amur Mainline (BAM), we investigate the influence of this project on post-communist voting behavior. We show that the BAM legacy reduces the share of votes for United Russia, the party of power of Putin’s regime, and leads to a larger share of votes for the Liberal-Democratic Party of Russia (LDPR). While the BAM legacy could be associated with a multitude of channels, we provide empirical evidence for at least one of them—the persistence of human capital, showing that BAM settlements are characterized by better educational outcomes than the control group.
Type 2 diabetes management in the homeless population: health inequality and the Housing First approach
Authors: Benz Fee
Published: December 2023

Homelessness is a significant public health concern, with a substantial homeless population in England. Homeless individuals face unique challenges, including a heightened risk of violence, inadequate nutrition, limited healthcare access and increased prevalence of co-morbidities. Type 2 diabetes (T2DM) is notably more prevalent among homeless individuals compared to the general population, leading to higher rates of diabetes-related emergency department visits and hospitalisations.
There is limited research examining diabetes management specifically in homeless populations, and a comprehensive review addressing the barriers and targeted interventions for this vulnerable group is currently lacking. This article aims to explore the health inequalities experienced by homeless individuals in relation to T2DM management, and to evaluate the Housing First approach as a potential intervention. Housing First, which provides immediate access to permanent housing, has demonstrated efficacy in enhancing housing stability and healthcare behaviours among homeless populations. Moreover, the available evidence suggests that Housing First programmes may improve diabetes-related outcomes, including HbA1c testing and medication adherence, and may lead to fewer hospitalisations.
association of dietary acid-base load with psychological disorders, sleep and circadian rhythm among obese and overweight women: a cross-sectional study
Authors: Mirzababaei Atieh , Mehranfar Sanaz , Shiraseb Farideh , Abaj Faezeh , Hajishizari Sara , C.T. Clark Cain , Mirzaei Khadijeh
Published: December 2023

Background: Epidemiological studies have reported that dietary acid load is associated with psychological disorders through different pathways. We aimed to examine the association of dietary acid-base load with psychological disorders, sleep and circadian rhythm.
Methods: This study was performed on 404 female subjects aged 18 years and above. We evaluated potential renal acid load (PRAL) and net endogenous acid production (NEAP) score by a validated food frequency questionnaire (FFQ) for Iran which contained 147 items. To assess psychological disorders, an Iranian validated version of the depression, anxiety and stress scale (DASS-21) was used. The Pittsburgh Sleep Quality Index (PSQI) and morning-evening questionnaire (MEQ) were applied to evaluate sleep quality and circadian rhythm status, respectively.
Results: After adjustment for a wide range of confounding variables, a significant positive association was observed between dietary acid-base load and severe depression (ORPRAL=1.10, 95% CI=1.01-1.19, p=0.02 and ORNEAP=2.46, 95% CI=1.41-14.61, p=0.02). Women in the high dietary acid base load category had higher anxiety (ORPRAL=1.12, 95% CI=1.02-1.23, p=0.01 and ORNEAP=1.80,95% CI=1.12-10.72, p=0.01). There was a strong positive relationship between dietary acid-base load and sleep disturbance (p<0.05). Additionally, circadian rhythm assessment showed that those with greater commitment to PRAL had 23% higher risk of being completely evening type, while the odds of being completely morning type were decreased by 15% and 12% across higher adherence to PRAL and NEAP.
Conclusion: Women with higher dietary acid-base load score had greater odds for depression, anxiety, psychological distress, sleep disturbance and evening-type circadian rhythm compared to lower ones.

We report a 61-year-old male patient without personal history of thyroid carcinoma or radiation exposure. In 2011, he presented with a cervical mass whose biopsy diagnosed a papillary thyroid carcinoma (PTC) in a lymph node metastasis (LNM). Total thyroidectomy with lymphadenectomy of central and ipsilateral compartment was performed. Histopathology identified a 2 mm follicular variant of PTC and LNM in 25/25 lymph nodes. The patient was treated with 150 mCi of radioactive iodine (RAI), followed by levothyroxine suppressive therapy. In 2016, a retrotracheal mass was diagnosed, suggesting local recurrence; patient was submitted to surgical excision and RAI therapy (120 mCi). Due to seizures, in 2019, a brain CT was performed that diagnosed brain metastases. The patient underwent debulking of the main lesion. Histopathology analysis confirmed a metastatic lesion with variated morphology: classical PTC and follicular pattern and hobnail and tall cell features. Molecular analysis revealed BRAFV600E in LNM at presentation and BRAFV600E and TERT promoter (TERTp) mutations in the recurrent LNM and brain metastasis. Based upon this experience we review the reported cases of subcentimetric PTC with brain metastases and discuss the molecular progression of the present case.

Learning points

Papillary microcarcinoma (PMCs) usually have very good prognosis with low impact on patient survival.

PMCs presenting in elderly patients with LNM at diagnosis may carry a guarded outcome.

Brain metastasis although rare indicate aggressive phenotypic features.

Patient risk stratification of PMCs based on histopathological analysis and genetic testing may have a significant impact on prognosis providing therapeutic markers, that may predict disease progression and overall outcome.

Adrenal lesions (ALs) are often detected in patients with multiple endocrine neoplasia type 1 (MEN1). However, they are not well described in MEN1, making their clinical management unclear. This study examined the prevalence and outcomes of ALs found in MEN1. We performed a retrospective chart review of patients diagnosed with MEN1 from 1990 to 2021. ALs were diagnosed using abdominal or thoracic imaging and classified as being unilateral or bilateral, having single or multiple nodules, and as having diffuse enlargement or not. Measurable nodular lesions were analyzed for their size and growth over time. Patients’ clinical and radiographic characteristics were collected. We identified 382 patients with MEN1, 89 (23.3%) of whom had ALs. The mean age at detection was 47 ± 11.9 years. We documented 101 measurable nodular lesions (mean size, 17.5 mm; range, 3–123 mm). Twenty-seven nodules (26.7%) were smaller than 1 cm. Watchful waiting was indicated in 79 (78.2%) patients, of whom 28 (35.4%) had growing lesions. Functional lesions were diagnosed in 6 (15.8%) of 38 that had functional work-up (diagnoses: pheochromocytoma (n = 2), adrenocorticotropic hormone-dependent hypercortisolism (n = 2), hyperandrogenism (n = 1), hyperaldosteronism (n = 1)); surgery was indicated for 5 (83.3%; n = 12 nodules), 2 of whom had bilateral, diffuse adrenal enlargement. Two patients were diagnosed with adrenocortical carcinoma and two with neoplasms of uncertain malignant potential. Radiographic or clinical progression of ALs is uncommon. Malignancy should be suspected on the basis of a lesion’s growth rate and size. A baseline hormonal work-up is recommended, and no further biochemical work-up is suggested when the initial assessment shows nonfunctioning lesions.
O ATLAS COMO CIÊNCIA DAS IMAGENS: HISTÓRIA DA ARTE E HISTÓRIA DA CULTURA EM GERHARD RICHTER E ABY WARBURG
Authors: Duarte Miguel Mesquita
Published: December 2023

Este artículo busca demostrar que es posible establecer importantes paralelismos entre el Atlas de Gerhard Richter (1962.2013) y el Atlas Mnemosyne de Aby Warburg (1924.29), pese a las diferencias históricas y temáticas que separan los dos proyectos. Partiendo de la amplia relación entre archivo, memoria e imagen, el artículo se centra en el análisis de tres aspectos fundamentales: el montaje-saber cómo base para la constitución de un relato sin texto; la importancia del componente autobiográfico y ficcional en los proyectos historiográficos de estos dos autores; y la centralidad de los procesos de inscripción, transformación y supervivencia de las imágenes, así como la respectiva correlación con el espacio de la memoria cultural, abordada aquí en su multiplicidad de saberes y objetos, pero también como principio ético-científico de construcción simbólica e interpretación del saber histórico. Aportando pistas para posteriores estudios comparativos entre Richter y Warburg, —hasta la fecha prácticamente inexistente en la literatura especializada (el texto de Buchloh sobre el archivo anómico, de 1999, toca sólo superficialmente esta relación)— el artículo pretende también contribuir a la reevaluación epistemológica de algunos de los significados, valencias y conceptos inherentes a los atlas de estos dos “historiadores-artistas” alemanes.

Published: December 2023

Snake grass fiber was used as a supporting material in an epoxy matrix. The goal was to develop a lightweight structural material. To enhance the interfacial bonding between the snake grass (Sansevieria ehrenbergii) fiber and polymer matrices, the fiber underwent chemical treatment with NaOH. Samples were prepared with both neat and treated fibers mixed with epoxy at various volume percentages. The mechanical properties of snake grass fiber exhibited improvement with increasing fiber length and fixation, reaching optimal values at 20 mm length and 20% v/v fixation. Dynamic mechanical analysis (DMA) demonstrated superior energy absorption by the composite up to 140 °C, irrespective of repetition. Thermogravimetric analysis (TGA) indicated rapid degradation of untreated fiber with a residue level of 0.2%, while the snake grass composite (25% v/v) exhibited stable residue content at 11%. Microscopic evaluation using a scanning electron microscope provided insights into the morphology of the fiber surface.

Published: December 2023

The objective of this work was to evaluate whether the chemical composition of wood and its crystallinity can help in the analysis of degradation by fungi and insects in logs of Amazonian wood species stored in a stockyard. For this study, wood from five commercial species that had been stored in an open yard for six months was used. The scale of degradation by fungi and insects, the moisture content of the logs, the total extractive content, lignin, holocellulose and the crystallinity were evaluated. It was concluded that the position of the logs in the stacks, associated with the storage time, influenced the evaluated characteristics. It was also observed that X-ray diffraction has potential for analysis of the degradation by fungi and insects in logs of Amazonian species stored in the stockyard.
Letters from the Past: Justinas Marcinkevičius’ Letters to His Teacher Genovaitė Andrašiūnienė
Authors: Bandoriūtė-Leikienė Salomėja
Published: December 2023

Nowadays, the long-standing communication by letters has changed a lot. A couple of decades ago, writing letters to another city, country or simply to someone who lives further away was a completely normal activity. Today, paper letters are usually only documents or postcards. Thus, it is interesting and meaningful to study letters as a disappearing form of communication. Researching letters is interesting for representatives of various branches of science. Investigating ego documents, especially letters, gives us an opportunity to find out more about the past communication, sender and receiver of the letter and the general discourse of the researched period. Reading letters, especially letters written by famous public figures, is interesting not only for the scientists, but also for the regular readers. Furthermore, it justifies the taboo set by social norms – prohibited reading of stranger’s letters.

The subject of this article are the letters of the Lithuanian poet Justinas Marcinkevičius to his teacher Andrašiūnienė, written in 1949–1961, after leaving Prienai to study at Vilnius University. Andrašiūnienė was a famous intelligent of Prienai district, a teacher of the Lithuanian language, who financially and morally supported her talented students, including famous poet Marcinkevičius and linguist Jonas Kazlauskas. The leads of the existence of these letters circulated among the people of Prienai for many years, until a few years ago they accidentally came into poet’s family hands (Marcinkevičius himself did not know about the existence of these letters). There are 44 letters of Marcinkevičius to teacher Andrašiūnienė, which were written while he was studying at Vilnius University. 43 letters are perfectly preserved, but one is no longer legible, because a third of the text is damaged.

The research of the letters reveals a close relationship between young poet Marcinkevičius and his teacher: a son-mother relationship. Marcinkevičius’ choice to call the teacher mother, mommy, confirms the fact that he is missing for mother’s care and attention (he lost his real mother in his early adolescence). Andrašiūnienė was not only a financial supporter, guardian, but also the first critic of the young poet’s writing. This critique significantly formed poets’ personality.

The young poet’s letters reveal his talent for writing: the texts are fluent and literary. Also, there are a lot of stories about his achievements and creative downfalls. Marcinkevičius is carefully writing about his negative position towards the ideology of the time. It is interesting to read letters where Marcinkevičius is arguing and getting angry with his teacher. These letters reveal the rebellious side of the poet, which is completely unexpected. The opportunity to look at Marcinkevičius’ youth by reading his letters deepens the knowledge of the change of the poet’s work and the formation of his personality.

Pengembangan Primer Diagnostik Menggunakan Penanda mat-K Secara In Silico untuk Mendeteksi Kelangkaan Jenis Tumbuhan Di Indonesia
Authors: Dzikrina Hanina , Hidayat Topik , Sriyati Siti
Published: December 2023

Indonesia merupakan negara dengan kekayaan biodiversitas tertinggi di dunia. Terdapat sekitar 40.000 jenis tumbuhan yang tumbuh di Indonesia dan sebagian besar tumbuhan sudah menunjukkan kelangkaan. Penentuan kelangkaan suatu jenis tumbuhan dapat diketahui berdasarkan distribusi populasinya, namun membutuhkan waktu yang cukup lama. Ketidakstabilan genom akan terjadi pada jenis tumbuhan langka, karena tidak mampu beradaptasi pada ekosistem. Banyaknya tumbuhan yang terancam punah dan habitat asli yang rusak, maka mengharuskan para peneliti untuk mengetahui keberadaan dan melakukan pendataan terhadap keragaman jenis tumbuhan di Indonesia secara cepat. DNA barcoding merupakan teknik yang dikembangkan untuk mempercepat dan mempermudah proses identifikasi organisme dengan menggunakan potongan DNA tertentu. Tujuan dari penelitian ini adalah mencari primer spesifik untuk mendeteksi status kelangkaan pada tumbuhan menggunakan penanda mat-K secara in silico. Gen mat-K merupakan penanda umum yang direkomendasikan untuk analisis pada tumbuhan. Metode yang digunakan yaitu dengan pendekatan secara in silico karena waktu yang diperlukan relatif lebih singkat dan murah. Penelitian ini berhasil mendapatkan sepasang primer forward 1:F_1635–1657 dan primer reverse 1:R_2093–2113 dengan persentase keberhasilan amplifikasi yang dicapai sebesar 66%. Kedepannya, primer ini dapat digunakan untuk mengidentifikasi status kelangkaan pada tumbuhan.AbstractIndonesia is a country with the highest biodiversity wealth in the world. There are around 40,000 types of plants that grow in Indonesia and most of the plants are rare. Determining the rarity of a plant type can be determined based on its population distribution, but it takes quite a long time. Genome instability will occur in rare plant species, because they are unable to adapt to the ecosystem. The large number of plants that are threatened with extinction and their natural habitats are damaged requires researchers to quickly identify the existence and collect data on the diversity of plant species in Indonesia. DNA barcoding is a technique developed to speed up and simplify the process of identifying organisms using certain pieces of DNA. The aim of this research is to look for specific primers to detect rarity status in plants using mat-K markers in silico. The mat-K gene is a general marker recommended for analysis in plants. The method used is an in silico approach because the time required is relatively shorter and cheaper. This research succeeded in obtaining a pair of forward primers 1:F_1635–1657 and reverse primers 1:R_2093–2113 with a successful amplification percentage of 66%. In the future, this primer can be used to identify rarity status in plants.

OBJECTIVES

To examine the prevalence and trends in severe obesity among 16.6 million children aged 2 to 4 years enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) from 2010 to 2020.

METHODS

Severe obesity was defined as a sex-specific BMI for age ≥120% of the 95th percentile on the Centers for Disease Control and Prevention growth charts or BMI ≥35 kg/m2. Joinpoint regression was used to identify when changes occurred in the overall trend. Logistic regression was used to compute the adjusted prevalence differences between years controlling for sex, age, and race and ethnicity.

RESULTS

The prevalence of severe obesity significantly decreased from 2.1% in 2010 to 1.8% in 2016 and then increased to 2.0% in 2020. From 2010 to 2016, the prevalence decreased significantly among all sociodemographic subgroups except for American Indian/Alaska Native (AI/AN) children. The largest decreases were among 4-year-olds, Asian/Pacific Islander and Hispanic children, and children from higher-income households. However, from 2016 to 2020, the prevalence increased significantly overall and among sociodemographic subgroups, except for AI/AN and non-Hispanic white children. The largest increases occurred in 4-year-olds and Hispanic children. Among 56 WIC agencies, the prevalence significantly declined in 17 agencies, and 1 agency (Mississippi) showed a significant increase from 2010 to 2016. In contrast, 21 agencies had significant increases, and only Alaska had a significant decrease from 2016 to 2020.

CONCLUSIONS

Although severe obesity prevalence in toddlers declined from 2010 to 2016, recent trends are upward. Early identification and access to evidence-based family healthy weight programs for at-risk children can support families and child health.
Three-dimensional (3D) transthoracic echocardiography in Cor Triatriatum Sinister: Make new friends but keep the old
Authors: Basile Paolo , Santoro Daniela , Guaricci Andrea Igoren
Published: December 2023

Cor Triatriatum Sinister (CTS) represents a rare congenital cardiac defect characterized by the presence of a fibro-muscular membrane separating the left atrium into two cavities. During adulthood CTS may be asymptomatic and incidentally found during imaging diagnostic workflow. Bidimensional (2D) transthoracic echocardiography (TTE) is considered the first-line imaging technique for the evaluation of CTS. Cardiac magnetic resonance (CMR) and transoesophageal echocardiography (TEE) are advanced diagnostic tools, usually required to obtain additional data. When these diagnostic techniques are contraindicated or not available, three-dimensional (3D) TTE may provide useful information which may help in the morphological assessment of CTS. Moreover, this widespread technique is safe and frequently available in the echocardiography laboratories, although the acoustic window and the training of the operator may be limiting factors. With this case report we sought to emphasize the usefulness of this technique as a valid alternative to CMR and TEE in selected settings.
El interés de Augusto para el Ebro Medio y el empleo del ejército romano. El caso del miliario de Santacara («CIL» XVII/1, 151) (Navarra)
Authors: Calonge-Miranda Adrián
Published: December 2023

En el año 2015 se dio a conocer el octavo miliario de Santacara fechado durante el gobierno de Augusto. Pese a su reutilización como parte de un edificio con fines agrícolas, se ha conservado gran parte de la inscripción: la filiación y los títulos. Gracias a la comparativa en cuanto a la distribución de la titulatura imperial de la inscripción viaria carense con tres epígrafes de Ejea de los Caballeros y Castiliscar (provincia de Zaragoza, Aragón) que prueban la intervención de legiones en la construcción de calzadas, es posible establecer paralelismos. Por todo ello, se propone que el ejemplar de la antigua ciudad de Cara, también fuera realizada en el marco de unas obras planificadas y ejecutadas por el ejército.
El estudio tiene también por objeto hacer un repaso de la intervención de la administración de Augusto en el Ebro Medio y en el territorio vascón tanto en las ciudades como en la red viaria. Además, de una reflexión sobre la impor tancia de la malla radial de calzadas en el entorno de Caesaraugusta o la importancia de las conexiones con los Pirineos.

Fast finite-time backstepping controller for a quadrotor UAV under state constraints
Authors: Mung Xuan Nguyen , Le Thanh Lanh , Nguyen The Mich
Published: December 2023

Quadrotors have gained popularity in a wide range of applications. In this paper, a new approach for solving the tracking control problem of quadrotors with full-state constraints is presented. The proposed method involves a backstepping control scheme integrated with a fast finite-time filter. First, necessary state transformations are performed to support the design of the finite-time filter and controller. Next, the controller is formulated based on the backstepping technique. All the state constraints are taken into consideration in the controller. However, it is well-known that the backstepping control design can lead to the “explosion of complexity” when calculating time derivatives of certain nonlinear functions. Therefore, the proposed filter comes to provide a solution for estimating the time derivatives with the estimation errors converging to zero in finite time. The closed-loop system's finite-time stability is rigorously proved using the Lyapunov theory, despite the state constraints. Simulation results demonstrate the feasibility and efficacy of the proposed method.

To understand and solve budget deficit problems, some academics propose budgets cuts while some suggest increase in taxes. The purpose of this study is to check the causal relationship among ten countries from two regions, south and eastern Asia, where all countries are developing except, Japan. The relationship is tested among three fiscal variables for the period of twenty-seven years from 1980 to 2017. For analysis purposes, Augmented Dickey Fuller test, Toda and Yamamoto Granger Causality Test and Johnson co-integration tests has been used. The results reveal three co-integrating effects for, Bangladesh and Mongolia, two for India and Japan, one for Sri Lanka, Nepal, China, South Korea, North Korea, while non for Pakistan. The Toda and Yamamoto Granger causality tests reveal evidence of tax-and-spend hypothesis for China, Pakistan, and Nepal. For Nepal, we found support for spend-and-tax hypothesis. There is evidence of neutrality for Japan, South Korea, North Korea, Mongolia, India, Sri Lanka, and Bangladesh. The results validate that south and eastern Asian countries tax policies have lessor impact to reduce budget deficits and do not offer permanent solution for fiscal problems. Our findings support increase in taxes may be a good solution to budget deficit problem, but it can be reduced if revenues and expenditures are controlled simultaneously. Major policy implications include, raising tax rates in nations like China, Pakistan, and Nepal, to increase revenue and strengthen fiscal sustainability, the significance of government spending reduction as a key tactic for managing budget imbalances, the importance of balancing both revenue generation and expenditure and flexibility in approach and continual monitoring of fiscal indicators.

Published: December 2023

Silver nanoparticles (AgNPs) are useful substances with a wide range of uses. utilizing the extract taken from the peels of the Rheum ribes L.(Rr) fruit growing in the Erzurum region, silver nanoparticles were speedily created in this study utilizing a quick, easy, and environmentally friendly technique without harmful stages. In order to evaluate the attributes of the synthesized Rr-AgNPs, FE-SEM or TEM micrographs were utilized to characterize the morphology of the AgNPs. A UV-visible spectrophotometer was used to assess the highest absorbance bands of RR-AgNPs. These data were used to produce RR-AgNPs, which were characterized as having exclusively negative surface charges of -25 mV, a spherical shape, maximum absorbance at 428 nm wavelength, and 96 nm size distribution. The effectiveness of the produced AgNPs for usage in medical applications was assessed using the MTT technique with microdilution. Minimum Inhibition Concentrations of Rr-AgNPs on pathogen strains were found to range from 0.03-0.50 mg/L. Additionally, it was discovered that AgNPs effectively suppressed malignant cells in the investigation for the anticancer effects of AgNPs, with rates of 86.27%, 74.67%, and 73.49%. Healthy cells were not subjected to any inhibitory effects at the same concentrations that caused this result.

Published: December 2023

RESUMO Este trabalho de pesquisa se propõe a indagar sobre a estética nas organizações, a partir de uma perspectiva semiótica, e a identificar quais são as percepções que as pessoas têm sobre nove dimensões das organizações em que atuam. Para isso, foi selecionada uma amostra de 60 pessoas, entre as quais 75% trabalham como docentes na modalidade virtual na Fundação Getúlio Vargas, no Rio de Janeiro. Os resultados permitem concluir que as valorações, tais como: os aspectos culturais, os efeitos pragmáticos das ações e os propósitos das organizações se percebem como mais importantes que os processos - planos, ações e avaliações; e os fundamentos - princípios, táticas e estratégias. A principal conclusão que se infere desta pesquisa é que os docentes valoram um clima organizacional sem estresse, a fim de favorecer a criatividade e a inovação. Entendem que uma cultura em que prevaleça a ética e a transparência contribui para que a organização tenha reconhecimento público, ou seja, tenha uma boa imagem.
