Published: November 2024

Abstract
Sulfur dioxide (SO2) is a sulfur-containing molecule expected to exist as a solid in the interstellar medium. In this study, we have performed laboratory experiments and computational studies on the surface reactions of solid SO2 with hydrogen atoms on amorphous solid water (ASW) at low temperatures. After 40 minutes of exposure of SO2 deposited on ASW to H atoms, approximately 80% of the solid SO2 was lost from the substrate at 10–40 K, and approximately 50% even at 60 K, without any definite detection of reaction products. Quantum chemical calculations suggest that H atoms preferentially add to the S atom of solid SO2, forming the HSO2 radical. Further reactions of the HSO2 radical with H atoms result in the formation of several S-bearing species, including HS(O)OH, the S(O)OH radical, HO–S–OH, HS–OH, and H2S. In codeposition experiments involving H and SO2, we have confirmed the formation of H2S, HS(O)OH, and/or HO–S–OH. However, the yields of these S-bearing species are insufficient to account for the complete loss of the initial SO2 reactant. These findings suggest that some products are desorbed into the gas phase upon formation. This study indicates that a portion of the SO2 in ice mantles may remain unreacted, avoiding hydrogenation, while the remainder is converted into other species, some of which may be subject to chemical desorption.

Abstract
We present a catalog of 32,162 12CO molecular clouds that covers the northern outer Galactic plane (l = [15°, 165°] and l = [195°, 230°], and b = [−5.°25, +5.°25]). The catalog was produced using a DBSCAN algorithm applied to the Milky Way Imaging Scroll Painting project data. We systematically analyze both the integrated properties and scaling relationships of these molecular clouds across different Galactocentric radii (8 < R
GC < 26 kpc). An interesting finding is that each cloud property’s mean, median, and maximum values generally decrease systematically with increasing R
GC, approximated quantitatively by exponential functions. The mass and size spectra for the entire sample show power-law indices of γ = −2.00 ± 0.13 and an upper mass limit of M

⊙, and γ = −3.68 ± 0.48 with an upper size limit of R

We find that 44.3% of the molecular mass resides in gravitationally bound structures, a proportion significantly higher than systematic studies from the CfA survey and external galaxies. Moreover, comparisons among different R
GC subsamples also reveal a decrease in the amount of bound mass with increasing R
GC. The scale length of the molecular disk is estimated to be approximately 2 kpc. These results, based on a constant CO conversion factor of

A Comprehensive Catalog of UVIT Observations. I. Catalog Description and First Release of Source Catalog (UVIT DR1)
Authors: Piridi Sonika , Kumar Ranjan , Pandey Divya , Pradhan Ananta C. 
Published: November 2024

Abstract
We present the first comprehensive source catalog (UVIT DR1) of ultraviolet (UV) photometry in four far-UV (FUV ∼ 1300−1800 Å) and five near-UV (NUV ∼ 2000−3000 Å) filters of the Ultraviolet Imaging Telescope (UVIT) on board AstroSat. UVIT DR1 includes bright UV sources in 291 fields that UVIT detected during its first 2 yr of pointed observation, encompassing an area of 58 deg2. We used the ccdlab pipeline to reduce the Level 1 data, SExtractor for source detection, and four photometric procedures to determine the magnitudes of the detected sources. We provided the 3σ and 5σ detection limits for all the filters of UVIT. We describe the details of observation, source extraction methods, and photometry procedures applied to prepare the catalog. In the final UVIT DR1 catalog, we have point sources, extended sources, clumps from nearby galaxies, globular clusters, open clusters, planetary nebulae, and gaseous nebulae. There are 239,520 unique sources in the combined UVIT DR1, of which 70,488 sources have FUV magnitudes, and 211,410 have NUV magnitudes. We crossmatched and compared noncrowded sources of UVIT with the Galaxy Evolution Explorer and Gaia source catalogs. We provide a clean catalog of the unique sources in various UVIT filters that will help further the multiwavelength scientific analysis of the objects.

Abstract
The Didymos Reconnaissance and Asteroid Camera for OpNav (DRACO) was the only instrument on board NASA’s Double Asteroid Redirection Test spacecraft. DRACO had a 2628.326 mm focal length Ritchey–Chrétien telescope with a 208.28 mm aperture and a 0.29° field of view (FOV). The camera used a front-side-illuminated complementary metal–oxide–semiconductor (CMOS) sensor, BAE CIS2521F, with 2048 × 2048 illuminated pixels. DRACO worked with an onboard image processor to support autonomous targeting and ensure impact with Dimorphos, the secondary asteroid in the 65803 Didymos system, on 2022 September 26. This paper covers the calibration and in-flight performance of DRACO, including descriptions of ground and in-flight activities, instrument characterization, the calibration pipeline, and delivered Planetary Data System (PDS) products. DRACO exhibited low read noise and dark current that enhanced the instrument’s sensitivity, although the sensor’s nonlinearity and popcorn noise in global shutter mode required careful characterization and compensation to optimize terminal navigation performance. DRACO had a relatively circular point-spread function of less than two binned pixels across the full FOV. The combined calibration efforts achieved an absolute radiometric calibration (in both rolling and global shutter modes) of better than 20% and a relative calibration across an image of <0.2%, despite no formal radiometric requirements. DRACO acquired 259,290 images in flight, which have been delivered to the PDS in both raw and calibrated forms. DRACO’s excellent performance indicates that similar off-the-shelf CMOS detectors would be well suited for future planetary missions in low-radiation environments.
Les successeurs de Néron et la Maison Dorée
Authors: Perrin Yves 
Published: November 2024

Le sort de la Domus Aurea après Néron est abordé au fil des pages des études sur Vespasien et ses successeurs ; l’historiographie dominante veut que Vespasien ait tout fait pour rejeter la résidence dans l’oubli et que ses successeurs aient poursuivi la même politique. Le renouvellement des connaissances archéologiques, la prise en compte de données épigraphiques, paléographiques et archivistiques peu ou pas exploitées et le primat accordé à une problématique historique invitent à réviser le tableau. Cet article fait le point sur les transformations post-néroniennes qui caractérisent chaque aire de la Domus Aurea en approfondissant l’étude de la fabrique de l’Oppius et de la domus Titi, puis en propose un décryptage politique : si les successeurs de Néron condamnent la scandaleuse résidence dans le discours, ils en cultivent habilement et efficacement l’héritage pour affirmer la nature personnelle de leur pouvoir.
Autour de L’archéologie industrielle en France (1980) de Maurice Daumas
Authors: Dorel-Ferré Gracia 
Published: November 2024

L’article examine la publication et l’impact du livre de Maurice Daumas, dans le contexte de la sensibilisation au patrimoine industriel. Seul à opérer « un tour de France » de l’archéologie industrielle, son travail ambitieux n’a pas été remplacé mais il a eu pour conséquence d’établir un fossé entre l’archéologie industrielle considérée comme le prolongement de l’archéologie classique et le patrimoine, que Daumas n’a pas voulu prendre en compte en tant que tel. Malgré les tentatives ultérieures, ce fossé n’a jamais été comblé, affaiblissant pendant longtemps ce qui aurait pu être une discipline plurielle, mettant l’accent sur le technique, le social et le citoyen. Aujourd’hui, les architectes en font leur matière première, au niveau national, par des conversions et au niveau international en orientant leurs propositions de listes du patrimoine mondial.
Concevoir l’histoire des techniques en France (1950-1980) : l’apport de Maurice Daumas
Authors: Garçon Anne-Françoise 
Published: November 2024

Qu’est-ce que concevoir une histoire des techniques à une époque donnée ? Question difficile, qui suppose pour y répondre que soient conduites de nombreuses études de cas. Voilà pourquoi cet article se focalise sur Maurice Daumas (1910-1984). Trente années durant en effet, dans la France des années 1950-1980, Daumas a travaillé à constituer l’histoire des techniques en tant que discipline, trente années durant lesquelles, la France a connu successivement la reconstruction (1945-1955), une industrialisation effrénée (1955-1975), puis, à partir de 1975, une désindustrialisation brutale tandis que débutait la révolution numérique. Dans un premier temps donc, j’analyserai les fondements de la pensée de Daumas dans la décennie d’après-guerre (1945-1955). Puis, après avoir présenté les méthodes et concepts qu’il a déployés durant les années 1960, j’analyserai comment et pourquoi, à partir d’une conception identique de l’histoire des techniques, Maurice Daumas et Bertrand Gille se focalisèrent dans les années 1970, sur deux concepts différents, celui de complexe technique pour Daumas, celui de système technique pour Bertrand Gille et je montrerai que ni l’un ni l’autre n’a compris ou accepté la complémentarité de leurs approches. Je reviendrai pour conclure, sur l’apport et les limites de l’œuvre de Daumas et ce qu’elle offre aujourd’hui aux historiens des techniques.
The Organisation of Pottery Production in the First Urban Societies. Technical and Social Analysis of Pyrotechnologies and Potters’ Working Spaces in Southwest Asia (4th and 3rd millennium BCE)
Authors: Padovani Claire 
Published: November 2024

Les 4e et 3e millénaires av. n. è. constituent une période de mutations socio-politiques et économiques majeures, marquée par la naissance des premiers états et des premières sociétés urbaines en Asie du Sud-Ouest. De manière générale, la population augmente et se concentre. Par conséquent, la demande en poterie, le bien matériel le plus consommé par les habitants, s’intensifie. Comment les potiers organisent-ils la production (soit l’ensemble des activités qui permettent de créer les produits céramiques) pour répondre à cette demande de plus en plus importante ? Est-ce que cette organisation est homogène et évolue de manière linéaire sur tout le territoire ? Quels impacts ces changements ont-ils sur la maîtrise du feu pour la cuisson, une des tâches les plus délicates de la chaîne opératoire céramique ? L’économie ancienne est habituellement étudiée à travers les sources textuelles. Pourtant, certains paliers de transformation de la production sont nettement perceptibles dans les vestiges archéologiques. En particulier, des fouilles très récentes montrent qu'à partir de la deuxième moitié du 3e millénaire av. n. è., les premières manufactures de céramique à grande échelle, regroupant des dizaines de fours fonctionnant en même temps, sont installées dans la région du Tigre. En outre, certains groupes de potiers améliorent les techniques de cuisson afin d'optimiser la production de chaleur et d'économiser le combustible. La diffusion de ces innovations pyrotechnologiques met en évidence des réseaux de diffusion spécifiques. Cependant, la transformation de la production ne suit pas une complexification linéaire et continue, d’un mode de production « domestique » à « industrielle ». L’analyse des techniques de cuisson et de l’organisation spatiale des espaces de travail potiers permet de nuancer cette dichotomie des catégories de production. La manière dont les sites de production de poterie de différentes régions sont construits et utilisés par les potiers met en évidence la variabilité culturelle du développement économique et pyrotechnologique de chaque région, et offre une nouvelle perspective sur l'organisation sociale du travail pendant la période protohistorique.
Percutaneous release of plantar fasciitis
Authors: Negm Mohammad A. , Elshal Ehab A. , Abdelkader Mohammad E. 
Published: November 2024

Background and aim
Plantar fasciitis (PF) is reportedly the most common cause of pain in the inferior heel. It affects sedentary and athletic populations. Obesity and prolonged standing are risk factors for it. Diagnosis is primarily based on history and physical examination. PF is thought to be caused by biomechanical overuse from prolonged standing or running, thus creating microtears at the calcaneal enthesis.

Patients and methods
This was a single-center, prospective, observational, case series study that involved 20 patients with chronic PF. All patients were treated by percutaneous plantar fasciotomy, with a follow-up duration of 6 months.

Results
In our study, there were 20 patients (20 feet) in whom there was a significant change in American Orthopedic Foot and Ankle Scale from 44.75±8.61 before the operation to 90.45±11.69 in the first follow-up visit (2 months after operation) and to 90.9±13.35 in the second visit (6 months after the operation) and a significant change in visual analog scale from 6.8±1.06 before the operation to 1.45±1.96 in the first follow-up visit and to 1.7±2.54 in the second follow-up visit. Regarding postoperative patient satisfaction levels, 60% of patients were very satisfied and 15% were satisfied, whereas 25% were not satisfied. All patients in this study returned to their full activity at an average of 3.85±1.09 weeks.

Conclusion
The percutaneous release of plantar fascia was effective in the treatment of PF.
Evaluation of the effect of platelet-rich plasma on the healing of the lay-open surgically repaired sacrococcygeal pilonidal sinus
Authors: Megahed Hazem A. , Elmoursi Lamiaa Z. 
Published: November 2024

Background and aim
Pilonidal sinus disease is surgically treated by two main methods, which include excision with primary closure/flap repair or excision of the sinus with healing by secondary intention, which is highly prevalent because of its relationship with a lower incidence of recurrence. However, it is linked to extended healing periods. This study was performed to evaluate the role of platelet-rich plasma (PRP) in accelerating the healing of the lay-open surgically repaired sacrococcygeal pilonidal sinus.

Patients and methods
This randomized prospective trial was performed between October 2020 and September 2021 on 40 patients in the Surgery Department of Al-Azhar University Hospital in New Damietta with a simple sacrococcygeal pilonidal sinus. Two groups were randomly selected from among the patients: group A (control group), comprised 20 patients who underwent a complete removal of the pilonidal sinus using the lay-open method and group B (PRP group), comprised 20 patients who underwent the same procedure. The surgical wound was injected with PRP just after surgery and on postoperative days 3, 7, and 14.

Results
The PRP group (B) experienced accelerated healing and resulted in a significant difference weeks 2, 3, 4, and 5. All revealed a very significant difference. At week 6, it becomes significant again.

Conclusions
PRP therapy considerably shortens the healing time and postoperative pain associated with pilonidal wounds following surgery, also, the time needed to resume work or daily activities and complications are decreased.
A comparative study between classically inverted and temporally inverted internal limiting membrane flap technique in the treatment of macular hole
Authors: Hegazy Hassan M. , Gad Ashraf M. , Ibrahim Ibrahim F.M. 
Published: November 2024

Background and aim
A full-thickness retinal tissue defect affecting the anatomic fovea and, particularly, the foveola of the eye is referred to as a macular hole.
The study’s objective was to compare the visual and anatomical results of using a temporal inverted internal limiting membrane (ILM) flap and a classical inverted ILM flap in the surgical closure of stage IV idiopathic macular holes.

Patients and methods
A prospective, randomized, interventional, comparative study was conducted at Al-Azhar University hospitals on 40 eyes of 40 patients with macular holes randomized to two groups: group I (20 patients) undergone pars plana vitrectomy with classic inverted ILM flap and group II (20 patients) undergone pars plana vitrectomy with the temporal inverted ILM flap technique.

Results
In group I, there was statistically insignificant differences (P=0.648) between patients who had dissociated optic nerve fiber layer (DONFL) in their optical coherence tomography (OCT) images (yes group) (mean±SD=0.44±0.08), and patients without DONFL in their OCT images (no group) (mean±SD=0.41±0.12), and same observation found in group II at which there was no statistically significant difference (P=0.874) between patients who had DONFL in their OCT images (yes group) (mean±SD=0.47±0.12), and patients without DONFL in their OCT images (no group) (mean±SD=0.46±0.19).

Conclusion
There is no significant difference in the postoperative best-corrected visual acuity between the two techniques. The integrity of Ellipsoid zone (EZ) and External limiting membrane (ELM) is essential for the improvement of visual acuity after operation.
Preliminary Study: Expulsive Effect of Empagliflozin on Small Lower Ureteric Stones in Type II Diabetic Patients
Authors: Abdelaziz Alsayed S. , Abdalaziz Mohab AS. , Ebraheem Mostafa M. , Raheem Ali A. , Ghoneem Ayman M. 
Published: November 2024

Background and aim
Currently, a new oral diabetes medication comprises inhibition of the sodium-glucose co-transporter 2 (SGLT2), resulting in glycosuria, which may have a dislodging impact on stone ureter. The purpose of this trial was to examine and compare efficacy of empagliflozin in treatment of ureteric stones in type 2 diabetes patients with tamsulosin.

Methods
Between July 2018 and March 2020, 111 diabetic patients coming to urology outpatient clinics with a single 5–10 mm lower ureteral stone were randomly assigned to two groups: Empagliflozin group (Group A, n=54): Patients got an oral dose of 10 mg of empagliflozin once daily, and Tamsulosin group (Group B, n=57): Patients received tamsulosin 0.4 mg once daily but no SGLT2 inhibitor. The spontaneous passing stones, time required for expulsion, and unfavorable effects were assessed.

Results
There were no significant variations in baseline characteristics between the two groups of patients. In groups A and B, stone expulsion was reported in 75.9% and 77.1% respectively. In group A, the average time to expulsion was 11±4 days, while in group B, it was 13±6 days. The rate of spontaneous stone passage was insignificantly greater in group B, although the stone expulsion time was insignificantly shorter in group A than in group B. The unfavorable effects identified in both groups were comparable in severity and mildness.

Conclusions
In comparison to 0.4 mg tamsulosin, empagliflozin is a safe and efficient medical expulsive therapy for solitary lower ureteral stones < 10 mm in type 2 diabetes individuals.
Evaluation of apically extruded debris from root canal filling removal of the mesiobuccal canal of maxillary molars using XP shaper and protaper with two different irrigation
Authors: Mirsattari Sanaz , Jahromi Maryam Zare , Khabiri Masoud 
Published: November 2024

ABSTRACT

Background:
Periapical extrusion of debris for root retreatment will effectively improve the posttreatment inflammation and pain. The aim of this study was to investigate the extruded debris for root retreatment using XP shaper and ProTaper files.

Materials and Methods:
In his experimental laboratory study, 40 extracted human maxillary molars were used in this laboratory study. After disinfection and equalization of length, the samples were treated with a passive step-back technique and dressed. The samples placed in the tubes for retreatment were divided into four groups: (1) XP shaper file and hypochlorite, (2) XP shaper file and ethylenediaminetetraacetic acid (EDTA), (3) ProTaper file and hypochlorite, and (4) ProTaper file and EDTA. Then, the teeth were taken out of the tubes, and cleaned to collect the remaining apical debris. The weight of the tube and the extruded debris was measured again. Data were analyzed using the Kruskal–Wallis test (α =0.05).

Results:
The highest average of extruded debris was related to the XP shaper file with EDTA solution, and the lowest average was related to the ProTaper file with hypochlorite solution. Between the two files used with EDTA and hypochlorite solution, the average debris extrusion of the XP shaper file with EDTA solution was significantly higher (P < 0.05) compared to the ProTaper and XP shaper files with hypochlorite solution (P < 0.05).

Conclusion:
Regardless of the type of irrigant material, the ProTaper file can be a more suitable option than the XP shaper file for retreatment of the tooth root canal with minimal debris extrusion.
