Lightcurves and Rotations of Trans-Neptunian Objects in the 2:1 Mean Motion Resonance with Neptune
Authors: Thirouin Audrey , Sheppard Scott S. 
Published: July 2022

Abstract
We report the rotational lightcurves of 21 trans-Neptunian objects (TNOs) in Neptune’s 2:1 mean motion resonance obtained with the 6.5 m Magellan-Baade telescope and the 4.3 m Lowell Discovery Telescope. The main survey’s goal is to find objects displaying a large lightcurve amplitude that is indicative of contact binaries or highly elongated objects. In our sample, two 2:1 resonant TNOs showed a significant short-term lightcurve amplitude: 2002 VD130 and (531074) 2012 DX98. The full lightcurve of 2012 DX98 infers a periodicity of 20.80 ± 0.06 hr and amplitude of 0.56 ± 0.03 mag, whereas 2002 VD130 rotates in 9.85 ± 0.07 hr with a 0.31 ± 0.04 mag lightcurve amplitude. Based on lightcurve morphology, we classify (531074) 2012 DX98 as a likely contact binary but 2002 VD130 as a likely single elongated object. Based on our sample and the lightcurves reported in the literature, we estimate the lower percentage of nearly equal-sized contact binaries at only 7%–14% in the 2:1 resonance, which is comparable to the low fraction reported for the dynamically cold classical TNOs. This low contact binary fraction in the 2:1 Neptune resonance is consistent with the lower estimate of the recent numerical modeling. We report the Sloan g′, r′, and i′ surface colors of 2002 VD130, which is an ultra-red TNO whereas 2012 DX98 is a very red object based on published surface colors.

Authors: Adomako Isaac Agyekum , Venter Dalene , Sampane Donkor Eric , Engel-Hills Penelope 
Published: July 2022

Introduction: Radiology is a technical service that provides medical imaging for all sectors of healthcare. Hospital-acquired infections (HAIs) is a major challenge in radiology and this is exacerbated in contexts where the healthcare system is unable to provide adequate funding and attention to effective infection control measures. The objectives of this study were to audit current cleaning procedures through the observation of practices in a radiology department, and to determine the types and numbers of nosocomial pathogens present on selected radiology imaging equipment and accessories before and after decontamination.
Methodology: In phase one we observed seven radiographers to audit cleaning procedures and practices. In phase two we collected swab samples from selected radiology imaging equipment and accessories and then cultured them for identification of microbes.
Results: It was observed that radiographers partially practiced infection control measures. This was due to the absence of documented protocol for infection control procedures. Our results indicated that all the selected equipment and accessories were contaminated with microorganisms pre- and post-cleaning. The identified microbes were Staphylococcus aureus, Coagulase negative Staphylococci (CoNS), Bacillus species (spp.), Shigella spp., Shigella sonnei., Klebsiella spp., Salmonella paratyphi A (S. paratyphi A), Salmonella typhi (S. typhi), Providencia rettgeri, Enterobacter spp. and Citrobacter spp. and Methicillin resistant strains of Staphylococcus aureus (MRSA).
Conclusions: The research concluded that the recommended cleaning agents did not effectively reduce the number of microorganisms making the selected equipment and accessories fomites for nosocomial pathogens.

La correspondance entre marchands ifrīqiyens et pisans au début du XIIIe siècle
Authors: Ouerfelli Mohamed 
Published: July 2022

Le présent article se propose d’examiner les conditions, les circonstances et les modalités de la production d’un corpus de lettres expédiées au tout début du XIIIe siècle par des marchands tunisois à leurs homologues pisans pour traiter d’affaires commerciales, et surtout pour les inciter à reprendre leurs activités suspendues à la suite d’un acte de piraterie mené par des Pisans dans le port de Tunis. Ces lettres constituent un exemple original d’écriture marchande produite dans le cadre de relations commerciales entretenues entre l’Ifrīqiya et le monde latin. Elles ont été rédigées dans l’entourage du pouvoir par les services de la douane ou du gouverneur almohade de Tunis et expédiées dans un contexte précis, d’où les différences constatées par rapport à d’autres écritures, directes et pragmatiques, produites par des hommes d’affaires, comme le montrent les quittances rédigées par des membres de la communauté mudéjare de Valence et retrouvées dans les archives de la compagnie de Francesco di Marco Datini.
The present paper analyses the conditions, circumstances and terms of the production of a corpus of letters sent at the beginning of the XIIIth century by Tunis merchants to their Pisan counterparts in order to deal about trade businesses, but above all to prompt them to resume their activities, which had been suspended due to an act of piracy done by Pisans in Tunis harbour. These letters are an original example of trade writing produced within the framework of commercial relationship between Ifrīqiya and the Latin world. They have been written in the circle of the power by the customs house or by the almohad governor of Tunis, and sent in a particular context. This explain the differencies we can note with other writings, which are direct and pragmatic, produced by businessmen, as shown by the receipts written by members of the mudejar community of Valencia and found within the archives of the company of Francesco di Marco Datini.
Typologie des sources documentaires se rapportant à l’histoire du commerce en Russie au moyen Âge et au début de l’époque moderne (Xe-XVIIe siècle)
Authors: Kaštanov Sergej M. , Komočev Nikita A. 
Published: July 2022

Le développement du commerce en Russie au Moyen Âge et au début de l’époque moderne est illustré par diverses sources écrites à caractère juridique. Les plus importantes d’entre elles sont de type contractuel (traités extérieurs et intérieurs, testaments, actes d’achat, de crédit et de baux), contractuel-législatif (octroi d’immunités douanières et statuts douaniers), législatif (à tous les niveaux), administratif (comptes rendus, quittances, factures, requêtes et suppliques, certificats de statuts personnels, essentiellement pour l’époque moderne), et comptable (registres de comptes de monastères et registres de douanes, à partir du XVIe siècle seulement).The development of trade in Russia in the Middle Ages and the early modern period is illustrated by diverse sources written with legal character. The most important of them are of many types: contractual (external and internal treatises, wills, acts of purchase, of credit and leases), contractual-legislative (granting of customs immunities and customs statuses), legislative (at every level), administrative (reports, receipts, requests and petitions, certificates of personal statuses, essentially of early modern period), and accountable (registers of accounts of monasteries and registers of customs, only from XVIth century onwards).

Published: July 2022

INTRODUCTION: The study of how classroom layout and activities affect learning outcomes of students with different demographics is difficult because it is hard to gather accurate information on the minute by minute progression of every class in a course. Furthermore, the process of data gathering must produce an abundance of data to work with and hence must be automated.
OBJECTIVES: A machine learning model trained on images of a classroom and thus capable of accurately labeling the classroom layout and activity of many thousands of images much faster and cheaper than employing a human.
METHODS: Transfer learning can allow for preexisting computer vision models to be retrained on a smaller, more specific dataset in order to still achieve a highly accurate result.
RESULTS: In the case of the classroom layout, the final model achieved an accuracy of 97% on a four category classification. And for detecting the classroom activity, after experimentation with several different versions that could work on a very small sample sizes, the best model achieved an accuracy of 86.17%.
CONCLUSION: In addition to showing that using computer vision to determine human activities is possible albeit more difficult than layouts of inanimate objects such as classroom desks, the study shows the differences between the use of self-supervised learning techniques and data augmentation techniques in order to overcome the problem of small training data-sets.
In vitro and in vivo effects of Khaya grandifoliola C. DC. (Meliaceae) leaf on erectile dysfunction in male rats
Authors: Gbolade A.A. , Ahmadu N.B. , Igwe C.S. 
Published: July 2022

Background: Khaya grandifoliola C. DC. (Meliaceae) is exploited as a popular antimalarial herbal medicine in Nigeria, externally in treating skin diseases, and to enhance libido.Objectives: This study evaluates the aphrodisiac potential of K. grandifoliola leaf in male Wistar rats. Materials and methods: Aphrodisiac property was determined by oral administration of graded doses: 100, 250 and 1000 mg/kg of crude methanol (MeOH) extract of K. grandifoliola leaf, and 100 and 200 mg/kg each of aqueous (AQ) and dichloromethane (DCM) fractions to male rats using standard procedure. Sildenafil citrate and distilled water served as positive and negative controls, respectively. Sexual behavioural parameters like mounting, intromission and ejaculatory frequencies and latencies were recorded on day 7. Anti-lipid peroxidation effect and serum testosterone concentrations were also monitored.
Results: From the sexual behavioural study, MeOH extract of the leaf was active and significantly increased mount and ejaculatory frequencies, and decreased mount and ejaculatory latencies in a dose dependent manner, but had no effect on intromission latency and intromission frequency. Both AQ and DCM fractions were more active than extract, comparable to Sildenafil citrate, but DCM fraction was comparatively more active. Testosterone concentrations were also increased dose-dependently by all tested agents, but DCM fraction was the most active and comparable to Sildenafil citrate. Only DCM fraction significantly inhibited lipid peroxidation but was not comparable to Vitamin E.Conclusion: From all indications, MeOH extract and fractions of K. grandifoliola leaf which increased serum testosterone and sexual behavioural indices has potential for improving sexual dysfunction in males, and the more active DCM fraction qualifies for further phytochemical investigation to isolate active compounds. These findings therefore justify the acclaimed local use of K. grandifoliola leaf in treating male infertility.

Published: July 2022

Pinus peuce is a five-needle pine native to high-elevation montane habitats of the Balkans. This study aimed to assess the diversity and composition of fungal communities associated with soil, rootlets and living needles of P. peuce at three high-altitude forest sites with different edaphic conditions and stand characteristics in south-eastern Montenegro. In total, 90 samples of each substrate (needles, rootlets and soil) were sampled. DNA amplification using ITS2 rDNA as a marker and high-throughput sequencing resulted in 23,394 high-quality reads, representing 825 fungal taxa. There were 52.5% Basidiomycota, 43.9% Ascomycota and 3.6% Mucoromycotina. There were 118 unique fungal taxa in the rootlets, 230 in soil and 113 in the needles, and only 8 taxa were shared. The most common fungi in rootlets were Rhizopogon mohelensis (11.0%), Suillus americanus (8.4%), and R. fallax (6.9%), in soil – Phlebiopsis gigantea (5.1%), Tylospora asterophora (2.9%), and Sollicocossima terricola (2.7%), and in the needles – Dothideomycetes sp. (17.6%), Dothideomycetes sp. (10.7%), and Leotiomycetes sp. (6.5%). The results showed that functional tissues and the rhizosphere soil of P. peuce were inhabited by a high diversity of fungi. Fungal communities in the rootlets and soil were largely determined by the site conditions such as soil properties and forest stand composition.

Delivering premature HIS complexe maneuver in differentiating between paroxysmal supraventicular tachycardias
Authors: Thinh Do Duc , Thuy Nguyen Tran , Dong Tran Van 
Published: July 2022

Background: It is difficult to differentiate between paroxysmal supraventricular tachycardias in some circumstances. Delivering premature His complexes (PHC), a new maneuver, has been recently introduced. The study aimed to describe and evaluate initially the value of this maneuver.
Methods: From 12/2021 to 05/2022, 30 patients who underwent electrophysiological studies were diagnosed with AVRT or AVNRT, and successful RF ablations. The PHC maneuver was performed when making differential diagnoses.
Results: 12 AVRT cases and 18 AVNRT cases underwent the premature His complex maneuver. Delivering PHCs disturbed all AVRTs in both early PHCs (∆A1A2 = 21,33 ms) and late PHCs (∆A1A2 = 44,43ms). Late PHCs (∆PHC < 20ms) did not disturb the AVNRT circuit (∆A1A2 = 0ms). Early PHCs (∆PHC ≥ 20ms) with mean ∆PHC = 38,9ms would advance the next atrial potential of ∆A1A2 = 15,85ms, but it was significantly shorter than the atrial advancement of ∆A1A2 = 44,43ms in AVRT (p<0,05). In comparison with the prematurity of PHC, the advancement of the next atrial potential ∆A1A2 in AVRT was greater than or equal to it (∆A1A2-∆PHC ≥ 0ms, however in AVNRT was always shorter (∆A1A2-∆PHC ≤ -5ms). This maneuver had accurate results in all cases with a sensitivity and specificity of 100%.
Conclusions: This initial evaluation suggested that this maneuver had highly accurate in differentiating AVNRT and AVRT. Premature His complexes will absolutely disturb the AVRT circuit. Delivering late PHCs could not disturb the AVNRT circuit, and early PHCs would advance the next atrial potential with an amount shorter than the prematurity of PHC. Further studies are necessary to determine the value of the maneuver in clinical practice.

Transposition of the great arteries (TGA) is a complex cyanotic congenital heart disease, and only 10% of children with TGA can be alive through infancy. Rastelli operation is a standard surgical method for patient with TGA associated with ventricular septal defect (VSD) and pulmonary stenosis (PS). The aim of this report was to show short-term outcome of Rastelli operation in TGA; 3 patients (aged from 3 months to 4 years) were diagnosed TGA, VSD, atrial septal defect (ASD) and PS (2 severe pulmonary stenosis, 1 pulmonary atresia) with cyanosis, failure to thrive, baseline oxygen saturation values of 62% to 75%. All of 3 was performed Rastelli procedure and hospital discharged after 14 – 17 days postoperatively with saturation > 95%, no early complication, reoperation or death. Rastelli procedure in TGA associated with VSD, ASD and PS is initially well performed at the department of Pediatric Cardiac Surgery, Cho Ray hospital with satisfactory short-time outcome
