Abstract
The Kepler and TESS missions revealed a remarkable abundance of sub-Neptune exoplanets. Despite this abundance, our understanding of the nature and compositional diversity of sub-Neptunes remains limited, to a large part because atmospheric studies via transmission spectroscopy almost exclusively have aimed for low-density sub-Neptunes, and even those were often affected by high-altitude clouds. The recent TESS discovery of the hot, dense TOI-824 b (2.93 R
⊕ and 18.47 M
⊕) opens a new window into sub-Neptune science by enabling the study of a dense sub-Neptune via secondary eclipses. Here, we present the detection of TOI-824 b’s hot dayside via Spitzer secondary-eclipse observations in the 3.6 and 4.5 μm channels, combined with a reanalysis of its interior composition. The measured eclipse depths (142

K) indicate a poor heat redistribution (f < 0.49) and a low Bond albedo (A

B
< 0.26). We conclude that TOI-824 b could be an “exposed Neptune mantle”: a planet with a Neptune-like water-rich interior that never accreted a hydrogen envelope or that subsequently lost it. The hot dayside temperature is then naturally explained by a high-metallicity envelope reemitting the bulk of the incoming radiation from the dayside. TOI-824 b’s density is also consistent with a massive rocky core that accreted up to 1% of hydrogen, but the observed eclipse depths favor our high-metallicity general circulation model (GCM) simulation to a solar-metallicity GCM simulation with a likelihood ratio of 7:1. The new insights into TOI-824 b’s nature suggest that the sub-Neptune population may be more diverse than previously thought, with some of the dense hot sub-Neptunes potentially not hosting a hydrogen-rich envelope as generally assumed for sub-Neptunes.
(When) Can Wave Heating Balance Optically Thin Radiative Losses in the Corona?
Authors: De Moortel I. , Howson T. A. 
Published: December 2022

Abstract
Why the atmosphere of the Sun is orders of magnitudes hotter than its surface is a long standing question in solar physics. Over the years, many studies have looked at the potential role of magnetohydrodynamic (MHD) waves in sustaining these high temperatures. In this study, we use 3D MHD simulations to investigate (driven) transverse waves in a coronal loop. As the boundary-driven transverse waves propagate along the flux tube, the radial density profile leads to resonant absorption (or mode coupling) and phase mixing in the boundaries of the flux tube and the large velocity shears are subject to the Kelvin–Helmholtz instability (KHI). The combination of these effects leads to enhanced energy dissipation and wave heating. Considering both resonant and nonresonant boundary driving as well as different densities for the flux tube, we show that only wave heating associated with a resonant driver in a lower-density loop (with a loop core density ∼5 × 10−13 kg m−3) is able to balance radiative losses in the loop shell. Changing the model parameters to consider a denser loop or a driver with a nonresonant frequency, or both, leads to cooling of the coronal loop as the energy losses are greater than the energy injection and dissipation rates.
La recherche collaborative : au-delà de l’entre-soi, un entredeux de savoir émancipateur
Authors: Bert Catherine 
Published: December 2022

Pour faire face à l’incertitude et à la complexité du monde, nous avons besoin de coconstruire des savoirs robustes, ainsi que de croiser les expertises au sujet des différents registres de nos existences. La recherche collaborative se présente comme une voie spécifique pour répondre à ces besoins. Elle s’appuie sur une exigence démocratique de construire un savoir « avec » et non pas « sur ». L’intention de cet article est de proposer une réflexion sur les enjeux épistémologiques de la recherche collaborative. Ces enjeux seront développés non pas en répondant à trois questions, mais en les déployant : qui produit le savoir ? quel est le statut du savoir ? à quoi sert le savoir ? Au regard de ces questions, les enjeux épistémologiques apparaissent inextricablement liés à des enjeux éthiques et politiques.
La Serbie, équilibriste entre Russie et Occident
Authors: Bieber Florian , Cadenza Academic translations  
Published: December 2022

La Serbie a refusé de soutenir les sanctions de l’UE contre la Russie, suscitant par l’ambivalence de sa politique étrangère une attention redoublée de la communauté internationale. Cette position s’inscrit dans la continuité de la politique étrangère du pays. L’ambiguïté est une stratégie délibérée pour le président Vučić, qui entend ne pas être « coincé entre l’Est et l’Ouest » : elle lui permet de consolider son pouvoir à Belgrade et de maximiser sa marge de manœuvre sur le plan international.
A reaction to the French “non”? Or a case of institutional bricolage?
Authors: Anderlini Michel Vincent 
Published: December 2022

Comment la Commission européenne a-t-elle conçu sa nouvelle méthodologie d'élargissement malgré une certaine lassitude face à ce processus ? Plusieurs études ont montré que l'opposition française au lancement des négociations d'adhésion avec la Macédoine du Nord et l'Albanie en 2019 expliquait le contenu de la nouvelle méthodologie. Traditionnellement, la politique d'élargissement a été vue à travers le prisme de l´institutionnalisme rationnel : de ce point de vue, la nouvelle méthodologie serait le résultat d’un tel choc externe. Cet article soutient au contraire, en utilisant le cadre de l'institutionnalisme discursif et le concept de bricolage institutionnel, que la nouvelle méthodologie est le produit de quatre discours différents sur l'élargissement superposés les uns sur les autres.
Process of Economic Sanctions Success or Failure
Authors: Aghanouri Reza , Sahraii Hedayat 
Published: December 2022

Background:
Economic sanction is a United Nations' pressure tool on a target government and civilians for changing strategic decisions about violating international norms of behavior, but many authors argue that in several cases, sanctions do not work. A nonpolitical and noneconomic study about economic sanction outcomes is scarce. In this study, we reviewed the related official documents, translated the sanction process by neuroscience language, and tried to recognize the type of stress process related to different outcomes in the target countries.

Methods:
We do this job in three phases: phase one is related to the literal review, phase two focuses on definition analysis according to neuroscience approaches, and phase three comes on neuroscientific target analysis. Defining stress process related to different outcomes by neuroscience is mentioned in the discussion based on using of other papers' data.

Results:
Stress act of sanctions As: Act

things are means that how could sanctions affect civilians and run the process of social pressure in the target entities.

Conclusion:
We concluded that sanctions are always threatening political tools and their effectiveness completely depends on the politicians view to threat proximity and the type of response to stresses of sanctions.
Streptomyces sp. Vitnk9 Derived Compound against Fish Bacterial Pathogens
Authors: Nabila Mohammed Ishaque , Krishnan Kannabiran 
Published: December 2022

Background:
The extensive research in the field of aquaculture is essential to combat the fish bacterial diseases causing massive economic loss to the aquaculture industry and these pathogens remains to be a threat to human well-being due to consumption of fish and fish products as a major food source.

Methods:
This study focuses on extraction and identification of the antibacterial compound produced by Streptomyces sp. VITNK9 against selected fish bacterial pathogens.

Results:
Bioactivity-guided extraction of ethyl acetate extract and purification results in isolation of the lead compound 1-(2-hydroperoxycyclopentyl)-4-hydroxytridecan-7-one (HCHD) from Streptomyces sp. VITNK9 having a chemical formula of C18H34O4 and a molecular weight of 314.46 g/mol. HCHD (100 μg/ml) demonstrated antibacterial activity with the inhibition zone of 19.33 ± 0.47 mm and the MIC (minimal inhibitory concentration) of 3.125 μg/ml toward Edwardsiella tarda and 16.66 ± 0.47 mm and the MIC value of 12.5 μg/ml against Aeromonas
hydrophila. In silico molecular docking studies showed the interaction of HCHD with the drug target enzyme acetate kinase of E. tarda and A.
hydrophila. It showed the least binding free energy of-6.5Kcal/mol and-6.1 Kcal/mol with acetate kinase of E. tarda and A.
hydrophila, respectively.

Conclusion:
The outcome of this study suggests that the inhibition of bacterial acetate kinase by the lead compound HCHD and thereby affects the bacterial metabolism. Streptomyces species are more promising source for isolating antibacterial secondary metabolites for controlling fish bacterial pathogens.

Non-steroidal anti-inflammatory drugs (NSAIDs) are an important therapeutic class of drugs widely used to suppress acute or chronic pains and inflammatory diseases such as in rheumatoid arthritis (RA), osteoarthritis (OS) etc. The aim of this study was to investigate the random combination and individual effect of COX-2 inhibitors (NSAIDs) on the liver. This study was conducted using a total of 40 adults Wistar rats. The rats were divided into eight groups of 5 rats each. Group one was the control group, group 2 was given piroxicam (0.29mg/kg) daily, group 3 was given ibuprofen (5.71mg/kg) daily, and group 4 received diclofenac (1.42mg/kg) daily. Group 5 received piroxicam (0.29mg/kg bodyweight) plus ibuprofen (0.58mg/kg), group 6 received piroxicam (0.29mg/kg) plus diclofenac (1.42mg/kg) and group 7 received ibuprofen (0.58mg/kg) plus diclofenac (1.42mg/kg) respectively daily. Group 8 was given Piroxicam (0.29mg/kg bodyweight) plus Ibuprofen (5.71mg/kg) plus diclofenac (1.42mg/kg) daily. Intervention was over a period of 3days. Animals were sacrificed after 24 hours and the liver tissues were excised, some were fixed in 10% neutral buffered formalin for histological studies while others were placed in normal saline for biochemical analysis. The results revealed that there was no significant statistical difference in total bilirubin, ALT and AST when compared to the control. This suggests that NSAIDs may have no significant effects on the liver for this regimen. Histological changes observed were congested portal vein, haemorrhagic bile ducts, distortion of portal triad and sinusoids, and degeneration of hepatocytes. In conclusion, NSAIDs may have harmful effect on the cytoarchitecture of the liver which can lead to liver damage especially when given in high doses and in combination, but however it had no effect on liver function.
An unusual median nerve formation; A case report and literature review
Authors: Mohammed Abdelsalam Ahmed Abdelmotalab , Ali QM 
Published: December 2022

The Median nerve anatomical variation is commonly encountered. During the dissection of about 65 years of formalin-fixed male cadaver at the Department of Human Anatomy at National University Faculty of Medicine for undergraduate students in 2016-2017, the left upper limb showed that the median nerve was formed by the union of the three roots. However, the third root arose from the musculocutaneous nerve inside the coracobrachialis muscle, perforating the lower part of the muscle and joining the median nerve at the middle of the arm region. Knowledge of these variations is useful clinically, especially when evaluating symptoms of upper limb trauma, and it is also useful when performing surgical approaches.
Gender Differences in Experiences of Adherence to HIV/AIDS Management among HIV-Positive Adults attending a Tertiary Hospital in Rivers State, Nigeria
Authors: Luke A , Uzosike TC 
Published: December 2022

Background: Adherence to HIV/AIDS management is the fundamental mechanism for ending HIV/AIDS by 2030. Rivers State has the third-highest HIV/AIDS burden in Nigeria. This study aimed to gain insights into the gender differences in experiences of adherence to HIV/AIDS management among HIV patients attending the University of Port Harcourt Teaching Hospital, Rivers State Nigeria.
Methods: A qualitative study design was carried out among 24 adult HIV positive patients who were purposively selected. Four focus group discussions were conducted with six participants in each group (2-male groups and 2-female groups). Each session was audio-recorded with consent from participants, transcribed verbatim, and exported into ATLAS. Ti version-12 software for analysis. Results were presented in tables and diagrams, highlighting codes and quotations.
Results: The majority of respondents were within 30-39 years. Most participants understood adherence as the timely ingestion of antiretroviral medications. The commonest reasons for non-adherence among the female gender were shame, poor attitude of healthcare workers, lack of support from discordant spouses/partners, and long waiting times at the clinic. While the male gender reported financial constraints and fear of being embarrassed or stigmatized.
Conclusion: This study revealed the socio-cultural, economic, and psychosocial factors influencing adherence to HIV/AIDS management. Hence solutions proffered by discussants such as improving on personal efforts, disclosure to trusted persons, friendly behaviour of healthcare workers, family and spousal support should be considered by healthcare facilities, donor organizations, and the government.

Published: December 2022

Aim/objectives: It was aimed to assess the prevalence of latent TB among HIV+ patients, evaluate the coverage of isoniazid preventive therapy (IPT), the continuous risk of latent tuberculosis infection, and factors associated with the presence of latent Tb in HIV+ patients.
Methods: This is an analytical cross-sectional study of HIV+ patients attending the HIV clinic or admitted not previously treated for TB and did not have clinical and laboratory evidence of active TB and matched HIV-negative population attending our GOC. Data collected with a pre-tested investigator administered questionnaire included the age, sex, height and weight, medical and drug history, and relevant physical examination findings such as body temperature and respiratory rate. Active TB was excluded by history, sputum AFB Z-N staining, or GeneXpert test and chest radiography. Whole blood samples were collected from participants for QuantiFERON TB Gold Plus for quantification of Interferon Gamma Release assay (IGRA) in order to diagnose or exclude latent TB. Data were analyzed using IBM SPSS version 25.0 software at a level of significance of p < 0.05. Association between means and qualitative variables was analyzed with student-t-test and Chi-square test
Results: The mean ages of the HIV+ and control groups were 42.69 ± 9.91 and 41.29 ± 9.20 years respectively with no significant statistical difference. 76(95.0%) of HIV+ patients and 74(92.5%) controls had no symptoms of TB and chronic lung disease. 18(22.5%) HIV+ patients and 2(2.5%) controls were exposed to persons with chronic cough (p=<0.001). The prevalence of latent TB among HIV+ patients was 22.50% and 10.0% among controls (p- value=0.001). 8(44.4%) out of 18 with latent TB had prior use of IPT compared with 24 (38.7%) out of 62 without latent TB (p-value =0.67). CD4 count was a significant factor associated with the presence of latent TB among HIV+ persons (p-0.03). Similarly, there was a significant association between viral load and positive IGRA (p<0.001).
Conclusion: Latent TB infection remains significantly higher among HIV+ than HIV-negative patients which may account for the higher incidence of active disease amongst them. Isoniazid preventive therapy coverage was poor amongst HIV+ patients in this study.

Scythian language: current state in the context of historical and linguistic discussions
Authors: Чибиров А.Л. 
Published: December 2022

Рассматриваются вопросы современного состояния скифского языка. Уде- ляется внимание сопоставлению позиций историка-востоковеда и лингвиста С.В. Кул- ланды и его оппонента Ю.А. Дзиццойты, что представляет интерес для более полного освещения вопроса. Автор исходит из того, что вопрос идентификации языка скифов не теряет своей актуальности в свете этнополитических процессов, в которые во- влечена Россия в последние два десятилетия своей новейшей истории. Автор отме- чает, что, в ответ на новаторские предложения С.В. Кулланды по новому прочтению скифской ономастики и глосс, лингвисты выдвигают аргументы «против», основыва- ясь прежде всего на выводах классического языкознания. Подчеркивается, что теория польского лингвиста К.Т. Витчака о дифференциации скифского и сармато-аланского языков, получившая свое развитие в цикле статей С.В. Кулланды, аргументирована и подтверждена соответствующими результатами археологических раскопок. Сделан вывод о том, что с поиском и обнаружением новых свидетельств, связанных с языком скифов, теория К.Т. Витчака и С.В. Кулланды, возможно, получит подтверждение или будет опровергнута в дальнейших изысканиях лингвистов.
Considering issues of the Scythian language contemporary state, the article focuses on the comparison of scientific positions of S.V. Kullanda, a historian-orientalist and linguist and his opponent Yu.A. Dzitstsoity, that is of interest for more complete coverage of the problem. The author assumes that the question of the Scythian language identification does not lose its relevance, especially in the light of ethnopolitical processes in which Russia has been involved during the past two decades of its modern history. The author notes that in response to S.V. Kullanda's innovative suggestions on the new interpretation of the Scythian onomastics and glosses, linguists raise arguments against them, basing on the provisions of Classical Linguistics. The article emphasizes that a theory on differentiation of the Scythian and Sarmato-Alanic languages by a Polish linguist K.T. Vitchak, has been developed in a cycle of S.V. Kullanda's articles that provide arguments and appropriate results of archaeological excavations. The article draws a conclusion that with the search and discovery of new evidences related to the Scythian language, K.T.Vitchak and S.V. Kullanda's theory might obtain confirmation or be disproved in further linguistic studies.
