Authors: Deroide Carlos Alberto dos Santos
Published: November 2021

Este experimento foi conduzido na UniversidadeEstadual de Maringá objetivando avaliar o desempenho de cordeiras alimentadascom ração completa sob duas formas físicas: farelada ou peletizada. Foram utilizadas14 cordeiras ½ Dorper – Santa Inês (D-SI) distribuídas em dois grupos ao acaso,com sete animais por tratamento. A ração foi balanceada de acordo com o NRC (2007),utilizando-se como ingredientes básicos: milho, farelo de soja e feno deTifton; tendo 19,02% de proteína bruta e 72,96% de nutrientes digestíveistotais. Foram analisados os parâmetros de ingestão diária de matéria seca(IDMS), ganho de peso diário (GPD), conversão alimentar (CA) e adigestibilidade in vitro da matériaseca (DIVMS) da ração. Não se observou diferença entre os pesos finais dascordeiras para as duas formas físicas da ração, porém os valores de GPD, IDMS,CA e DIVMS foram melhores para as cordeiras alimentadas com ração peletizada.Assim, recomenda-se a recria de cordeiras com esta forma de ração.
Intrinsic device parameter extraction method for zinc oxide-based thin-film transistors
Authors: Yoon Minho , Lee Jiyoul
Published: November 2021

We present a device parameter extraction method that enables the reliable extraction of the intrinsic device parameters of zinc oxide (ZnO) thin-film transistors (TFTs). By assuming that mobility and contact resistance were modeled as gate bias-dependent power-laws, we derived a current–voltage relationship that decoupled from the contact resistance effect. In accordance with this derived relationship, we extracted the intrinsic mobility and contact resistance using the modified method, the values being consistent with the parameters extracted using the four-probe method.

Authors:   Department of Systems and Computer Engineering, Faculty of Engineering, Al-Azhar University, Cairo, Egypt.., El Fiky Ahmed Hashem
Published: November 2021

The COVID-19 will take place for the first time in December 2019 in Wuhan, China. After that, the virus spread all over the world, with over 4.7 million confirmed cases and over 315000 deaths as of the time of writing this report. Radiologists can employ machine learning algorithms developed on radiography pictures as a decision support mechanism to help them speed up the diagnostic process. The goal of this study is to conduct a quantitative evaluation of six off-the-shelf convolutional neural networks (CNNs) for COVID-19 X-ray image analysis. Due to the limited amount of images available for analysis, the CNN transfer learning approach was used. We also developed a simple CNN architecture with a modest number of parameters that does a good job of differentiating COVID-19 from regular X-rays. in this paper, we are used large dataset which contained CXR images of normal patients and patients with COVID-19. the number of CXR images for normal patients are 10,192 image and the number of CXR images for COVID-19 patients are 3,616 images. The results of experiments show the effectiveness and robustness of Deep-COVID-19 and pretrained models like VGG16, VGG19, and MobileNets. Our proposed Model Deep-COVID-19 achieved over 94.5% accuracy.
GRADUATE UNEMPLOYMENT: IMPLICATIONS FOR EDUCATIONAL PLANNING IN NIGERIA.
Authors: Dauda LIVALA, Sunsuwa
Published: November 2021

The paper investigates the problem of graduate unemployment and its underlying effects on the Nigerian economy vis-à-vis the role of educational planners. It emphasizes that graduate unemployment represents colossal waste in human capital development. The paper outlined some causes of graduate unemployment to include incongruity between the number of graduates and the existing job opportunities, obsolete curriculum, vocational and technical education not inbred in the university, and a poor foundation for entrepreneurship. The paper outlined some consequences of unemployment and presents entrepreneurship education as a panacea to unemployment. The paper noted some strategies required by educational planners to cater for those in the labour market. Some employable skills required at the labour market were also revealed. The paper recommends a commitment to intellectual and attitudinal empowerment through educational planning to engender tenacious self-reliance and egalitarian society in the long run. It also recommends developing a more practical-based programme and prioritizing curriculum reform amongst others to enhance job creation that will promote graduate employability at the Labour market.

Authors: Vargas Diana , Celis Luis , Lizcano Fernando
Published: November 2021

Objetivo: la obesidad ha aumentado en todo el mundo, no obstante existen pocas opciones terapéuticas novedosas y la inclinación a actividades cruentas para la terapia de obesidad y diabetes mellitus 2 no dejan de ser un riesgo. Con el fin de valorar el efecto de compuestos sobre la actividad de la célula grasa, estudiamos en forma preclínica la actividad de ácido valproico, tricostatin a (inhibidor de histonas deacetilasas) y eiD1 (inhibidor de eP300), el cual reduce la actividad de PParg en un modelo de células preadipocíticas 3T3-l1.

Métodos: se realizó transfecciones transitorias con lipofectamina a las células 3T3-l1 y 293. las células unipotentes 3T3-L1 fueron sometidas a diferenciación con el coctel específico para diferen- ciación y se les adicionaron los compuestos a concentraciones fisiológicas para las células. Se valoró la expresión de UCP1 mediante Western blot y los experimentos se realizaron por triplicado.

Resultados: se observó que el efecto de tricostatin a fue mayor que el del ácido valproico en actividad lipolítica, no obstante ambos compuestos ejercen una efecto aditivo sobre la actividad de eiD1 en la diferenciación de la célula adiposa. eiD1 es capaz de estimular la actividad de proteína UCP1, cuya expresión es propia del adipocito marrón.

Conclusiones: eiD1 es una proteína que puede ser referente para inducir una célula adiposa calori- génica más activa, reduciendo la acumulación de lípidos en célula grasa. el efecto de ácido valproico y tricostatin a pueden servir de parámetro para la búsqueda de nuevos planes terapéuticos dirigidos a la obesidad

Authors: Bhardwaj Abhishek , RATH MANORANJAN , Pareek Keshav , AAYUSH KUMAR
Published: November 2021

The main aim of the study is to analyze the heat transfer through the clay brick walls of the residential building to find out the dominant mode of heat transfer and incorporate various materials in the wall to reduce heat loss and increase energy efficiency. The transient thermal analysis was performed using the finite element method, and by employing a CFD program focused on heat transfer processes. Later, two models of building wall fragments incorporating the Phase change materials were developed to identify the optimal position of the PCM layer inside the wall and to investigate the role of PCM on the heat transfer rate. Insulation was done with the different types of plywood and finite element simulation was performed to study the change in heat transfer rate. Inserting plywood into the sandwich material with Chinese plywood can reduce the heat transfer content.

Opinitis. Het (on)vermogen tot zelfstandig oordelen
Authors: Schreijnders Rudy
Published: November 2021

We leven in een tijdperk van meningen. Op sociale media, in talkshows op tv en in talloze vlogs en blogs buitelen de meningen over elkaar heen. Iedereen lijkt overal iets van te vinden, en ook te móeten vinden. We staan met ons allen bloot aan een stortvloed van besmettelijke opinitis, die we overigens ook met ons allen veroorzaken. Veel meningen zijn aangepraat en er wordt veel nagepraat, beïnvloed door de bubbel waartoe men behoort of door publieke figuren en influencers die hun mening zó overtuigend presenteren dat grote groepen hun mening voor waar aannemen. De filosofie maakt al sinds de oudheid onderscheid tussen ‘meningen’, die schijnkennis vertegenwoordigen, en ‘waarheid’ op basis van kennis die voortkomt uit denken. Zelfstandig oordelen betekent in de eerste plaats onafhankelijk oordelen; onafhankelijk van meningen, drogbeelden en sentimenten. De bijdragen in deze bundel verkennen hoe onafhankelijk oordelen tot stand komt. Hoe kunnen we zélf oordelen over waarheid en geloofwaardigheid? Welke rol spelen anderen daarbij? Nabije anderen, maar ook bubbel-overstijgende inspirerende denkers, historische of fictionele figuren, die uitnodigen tot nieuwe interpretaties en ideeën. En hoe krijgt een oordeel gezag? Is dat door imiterende herhaling, door het volume van de spreker, door slaafse volgzaamheid? Of door eigen, zelfstandige interpretatie? In Opinitis gaan filosofen, theologen, cultuurhistorici en publicisten in op bovenstaande vragen. Zij onderzoeken vanuit verschillende invalshoeken hoe onze oordelen tot stand komen, hoe we ons verhouden tot de macht van de media en de invloed van de meerderheid, en hoe we aan onze eigen bubbel kunnen ontsnappen.

Published: November 2021

The management of panurethral stricture was still challenging and controversial. We presented a case of pan urethral strictures management by using a one-sided dissection of dorsal onlay buccal mucosal graft (BMG) urethroplasty (Kulkarni technique). A 53-years old man admitted with panurethral stricture who had previously undergone several procedures. Bipolar micturition cystourethrography procedure revealed 17 cm stricture length. One-sided dissection dorsal onlay buccal mucosal graft urethroplasty was performed. No drain was placed. The Foley catheter was removed four weeks after surgery, and the results of the micturition were favourable. No fistulae were found at a straight erection and meatus at a normal position. The postoperative flow rate (Qmax) was 24.9 ml/second. As a conclusion Kulkarni technique urethroplasty gained good outcome for panurethral stricture in our case.
The outcome of surgical resection in complete paraplegia patient due to thoracic schwannoma
Authors: Monica Maria , Ginting Bair
Published: November 2021

Spinal schwannoma is the most common benign intradural spinal tumor. However, studies regarding the neurological outcome of tumor resection in complete paraplegia patients are still lacking. The authors report a case of complete paraplegia due to primary intradural extramedullary low-grade schwannoma of the spinal cord. Surgery was performed 5 weeks after the paraplegia complaint first occurred. The patient did not regain motor nor sensory function in the 1-month follow-up, but resolution of pain was achieved. The patient was able to perform daily activity more comfortably. In the event of complete paraplegia, surgery should still be offered promptly as it can still benefit the patient. Possible factors that could have influenced the prognosis in our study are discussed.
The use of CONOX as a guide to the general anesthesia on laparotomy patients compared with standard clinical care– A pilot study
Authors: Jehosua Brillyan T , Suarjaya I Putu Pramana , Hartawan IGAG Utara , Senapathi Tjokorda Gde Agung
Published: November 2021

Background

Avoiding excessive doses of anesthesia was fundamental, mainly to reduce the adverse effect of anesthesia. Electroencephalography (EEG)-based monitors can be used to measure the depth level of anesthesia and guide intraoperative hypnosis drug and opioid administration. This study aims to evaluate the benefit of using CONOX monitor when administering anesthesia drugs in laparotomy procedures.

Method

Twenty patients aged 18-65 years with physical status ASA I-III who underwent major laparotomy surgery with general anesthesia total intravenous anesthesia (TIVA) were divided into two groups. Group A received general anesthesia guided with the CONOX monitor, while group B using standard clinical care. We later evaluate the total use of propofol and fentanyl, intraoperative hemodynamic profile, postoperative cognitive disorder (POCD), intraoperative awareness, postoperative nausea and vomiting (PONV), and moderate to severe pain in the post- anesthesia care unit (PACU).

Results

The mean total propofol used is lower in CONOX group (63.6 ± 11.7 mcg/kg/min vs. 74 ± 17.87 mcg/kg/min). A similar result was obtained with fentanyl. The CONOX group use a lower total of fentanyl (212.5 ± 32.3 mcg vs. 249 ± 54.6 mcg) than the control group. POCD was found to be more prevalent in the control group (5 vs 2 patients). While there is no report of intraoperative awareness.

Conclusion

The incidence of PONV and moderate to severe pain in PACU was similar between the two groups. This pilot study is a preliminary study to evaluate the benefit of using EEG-based monitors to adjust anesthesia drugs.

Published: November 2021

Patients with difficult airways who are going to undergo surgery under general anesthesia require special consideration from an anesthesiologist. Knowing the most significant risk of morbidity and mortality is often due to difficult cases of airway management. One of the most common complications and often becomes lawsuits in the field of anesthesia is dental trauma that occurs during the intubation process due to contact from laryngoscope blade to the teeth. This descriptive study will show the measured force exerted on the maxillary incisors at the time of performing laryngoscopy using a McGrath video laryngoscope in patients with a potentially difficult intubation (LEMON criteria ≥ 3). The contact force exerted on the maxillary incisors is measured using a special instrument. The contact force exerted on the maxillary incisors in patients with a potentially problematic airway was discovered to vary.
Perancangan dan Pembuatan Indikator Volume Kernel di Kernel Storage Bin pada Stasiun Nut and Kernel Pabrik Kelapa Sawit
Authors: Haq Idad Syaeful
Published: November 2021

Kernel Storage Bin (KSB) merupakan tangki penyimpan sementara kernel produksi di Stasiun Nut and Kernel yang terletak di atas. Proses pengiriman kernel produksi menuju KSB menggunakan konveyor Dry Kernel Distributing dan konveyor Cross Dry Kernel. Persoalan yang sering terjadi adalah kernel pada KSB mengalami penuh dan terjadi penumpukan kernel pada konveyor. Penyebab hal ini, karena operator tidak mengetahui kondisi kernel pada tanki KSB yang sudah terisi penuh, serta kernel berisiko tumpah jatuh ke lantai bagian bawah KSB. Atas dasar ini, perlu dibuat alat indikator di KSB untuk meminimalkan terjadinya penumpukan kernel saat KSB penuh dan mencegah terjadinya kerusakan konveyor, serta memudahkan operator mengontrol pengisian kernel di KSB. Metode penelitian menggunakan observasi langsung dalam mengidentifikasi penyebab masalah dengan metode Root Cause Analysis (RCA) dengan alat bantu diagram Ishikawa guna memperoleh akar persoalan beserta solusi yang diberikan. Alat indikator dibuat menggunakan sensor limit switch yang terhubung dengan bandul level dan panel indikator. Alat ini mampu bekerja baik dengan penanda visual dalam bentuk lampu indikator, serta penanda audio dalam bentuk suara sirine. Lampu indikator berwarna hijau akan menyala ketika tumpukan kernel di KSB masih dalam kondisi rendah (low), dan lampu indikator akan berwarna merah, serta sirine menyala ketika tumpukan kernel di KSB penuh (high). Taksiran total jumlah berat rata–rata kernel yang tertampung pada KSB-1 saat kondisi penuh adalah 85,50 ton, sedangkan pada KSB-2 adalah 90,89 ton dan KSB-3 adalah 62,75 ton. Pengujian putaran reverse otomatis motor listrik pada konveyor Dry Kernel Distributing saat KSB nomor-1, 2 dan 3 kondisi penuh memberikan hasil kinerja yang baik. Pemasangan alat indikator (berbasis visual dan audio) memberikan hasil kernel tidak mengalami penumpukan lagi di KSB. Kernel yang tidak menumpuk akan mengurangi kerusakan konveyor Cross Dry Kernel, serta memudahkan operator mengontrol penyimpanan kernel produksi.

This article is devoted to the development of a mechanism for ensuring the economic secu-rity of the coastal Arctic region. The analysis showed that in the Strategy of economic security of the Russian Federation for the period up to 2030 the mechanism of economic security for the regional level is not proposed, as well as indicators that take into account specific features in the development of territorial systems are not proposed. The absence of this mechanism does not contribute to the adoption of timely and effective man-agement decisions aimed at preventing the occurrence of adverse events and minimizing threats (damages).

Herein, we report precise variation of Fe and Mn constituent in the sodium magnate layered cathodes with the compositions of Na0.8Fe0.4Mn0.5O2, Na0.8Fe0.5Mn0.4O2, Na0.8Fe0.6Mn0.3O2, Na0.8Fe0.6Mn0.4O2, Na0.8Fe0.7Mn0.4O2, Na0.9Fe0.6Mn0.3O2 in order to attain a high performing cathode. Based on this transition metal stoichiometry, an interesting sodium magnate combination of Na0.8Fe0.6Mn0.3O2, with O3-type crystal phase, possess R3m space group along with the superior electrochemical behavior is obtained. On charge-discharge capacities in the range of 2.0-3.8 V at 0.1 C, it shows the comparatively higher performance of the first and the second charge capacity of 115 and 180 mAhg-1 and discharge capacity of 184 and 181 mAhg-1, respectively. The best sample was then compared with the closely related Na0.8Fe0.6Mn0.4O2, Na0.9Fe0.6Mn0.3O2 combination in terms of valence ratio and influence of excess sodium for the structure robustness, stability along with purity. The best sample with the composition Na0.8Fe0.6Mn0.3O2 does not show detectable impure phase while Na0.8Fe0.6Mn0.4O2 and Na0.9Fe0.6Mn0.3O2 shows a tendency of P-type (Cmca space group) behavior with 30.8% and 32.8%, respectively. The enhancement of iron constituent increases not only the performances but also the stabilization of sodium vacancy ordering and substitution of Mn with a substantial reduction of Jahn-Teller distortion, mounting biphasic characteristics and high peak intensity of 41.5 °.

Love in the family through the eyes of the writer Meir Shalev (and fragments of novel texts and analysis)
Authors: Rozin Vadim
Published: November 2021

The article presents small fragments of three novels by Meir Shalev, and the author on this material discusses the writer's understanding of love, family and personality. Why, he asks, is the fate of the family as portrayed by Shalev so sad, almost unconnected with love, and why the personality in novels is usually lonely? To answer these questions, an analysis of these three realities important for life is proposed, on the one hand, as Shalev understands them, on the other, how they currently look objectively. The author comes to the conclusion that at present in culture the understanding and concepts of family, love and personality are not coordinated with each other, which gives rise to numerous problems and a crisis of sociality. In parallel, he is trying to clarify the essence of the phenomena of love, family, personality and sociality discussed by Shalev.

Disk Masses and Dust Evolution of Protoplanetary Disks around Brown Dwarfs
Authors: Rilinger Anneliese M. , Espaillat Catherine C.
Published: November 2021

We present the largest sample of brown dwarf (BD) protoplanetary disk spectral energy distributions modeled to date. We compile 49 objects with ALMA observations from four star-forming regions: ρ Ophiuchus, Taurus, Lupus, and Upper Scorpius. Studying multiple regions with various ages enables us to probe disk evolution over time. Specifically, from our models, we obtain values for dust grain sizes, dust settling, and disk mass; we compare how each of these parameters vary between the regions. We find that disk mass decreases with age. We also find evidence of disk evolution (i.e., grain growth and significant dust settling) in all four regions, indicating that planet formation and disk evolution may begin to occur at earlier stages. We generally find that these disks contain too little mass to form planetary companions, though we cannot rule out that planet formation may have already occurred. Finally, we examine the disk mass–host mass relationship and find that BD disks are largely consistent with previously determined relationships for disks around T Tauri stars.
Probing Protoplanetary Disk Winds with C ii Absorption
Authors: Xu 徐紫 Ziyan 嫣 , Herczeg 沈雷 Gregory J. 歌 , Johns-Krull Christopher M. , France Kevin
Published: November 2021

We present an analysis of wind absorption in the C ii
λ1335 doublet toward 40 classical T Tauri stars with archival far-ultraviolet (FUV) spectra obtained by the Hubble Space Telescope. Absorption features produced by fast or slow winds are commonly detected (36 out of 40 targets) in our sample. The wind velocity of the fast wind decreases with disk inclination, which is consistent with expectations for a collimated jet. Slow wind absorption is mostly detected in disks with intermediate or high inclination, without a significant dependence of wind velocity on disk inclination. Both the fast and slow wind absorption are preferentially detected in FUV lines of neutral or singly ionized atoms. The Mg ii
λ
λ2796, 2804 lines show wind absorption consistent with the absorption in the C ii lines. We develop simplified semi-analytical disk/wind models to interpret the observational disk wind absorption. Both fast and slow winds are consistent with expectations from a thermal-magnetized disk wind model and are generally inconsistent with a purely thermal wind. Both the models and the observational analysis indicate that wind absorption occurs preferentially from the inner disk, which offers a wind diagnostic in complement to optical forbidden line emission that traces the wind in larger volumes.
Limits on Polarized Dust Spectral Index Variations for CMB Foreground Analysis
Authors: Osumi Keisuke , Weiland Janet L. , Addison Graeme E. , Bennett Charles L.
Published: November 2021

Using Planck polarization data, we search for and constrain spatial variations of the polarized dust foreground for cosmic microwave background (CMB) observations, specifically in its spectral index, β

d
. Failure to account for such variations will cause errors in the foreground cleaning that propagate into errors on cosmological parameter recovery from the cleaned CMB map. It is unclear how robust prior studies of the Planck data that constrained β

d
variations are due to challenges with noise modeling, residual systematics, and priors. To clarify constraints on β

d
and its variation, we employ two pixel space analyses of the polarized dust foreground at >3.°7 scales on ≈60% of the sky at high Galactic latitudes. A template fitting method, which measures β

d
over three regions of ≈20% of the sky, does not find significant deviations from a uniform β

d
= 1.55, consistent with prior Planck determinations. An additional analysis in these regions, based on multifrequency fits to a dust and CMB model per pixel, puts limits on

The cosmic black hole accretion density (BHAD) is critical for our understanding of the formation and evolution of supermassive black holes (BHs). However, at high redshifts (z > 3), X-ray observations report BHADs significantly (∼10 times) lower than those predicted by cosmological simulations. It is therefore paramount to constrain the high-z BHAD using independent methods other than direct X-ray detections. The recently established relation between star formation rate and BH accretion rate among bulge-dominated galaxies provides such a chance, as it enables an estimate of the BHAD from the star formation histories (SFHs) of lower-redshift objects. Using the CANDELS Lyα Emission At Reionization (CLEAR) survey, we model the SFHs for a sample of 108 bulge-dominated galaxies at z = 0.7–1.5, and further estimate the BHAD contributed by their high-z progenitors. The predicted BHAD at z ≈ 4–5 is consistent with the simulation-predicted values, but higher than the X-ray measurements (by ≈3–10 times at z = 4–5). Our result suggests that the current X-ray surveys could be missing many heavily obscured Compton-thick active galactic nuclei (AGNs) at high redshifts. However, this BHAD estimation assumes that the high-z progenitors of our z = 0.7–1.5 sample remain bulge-dominated where star formation is correlated with BH cold-gas accretion. Alternatively, our prediction could signify a stark decline in the fraction of bulges in high-z galaxies (with an associated drop in BH accretion). JWST and Origins will resolve the discrepancy between our predicted BHAD and the X-ray results by constraining Compton-thick AGN and bulge evolution at high redshifts.

We present a morphological and spectral study of a sample of 99 BL Lac objects using the LOFAR Two-Metre Sky Survey Second Data Release (LDR2). Extended emission has been identified at gigahertz frequencies around BL Lac objects, but with LDR2 it is now possible to systematically study their morphologies at 144 MHz, where more diffuse emission is expected. LDR2 reveals the presence of extended radio structures around 66/99 of the BL Lac nuclei, with angular extents ranging up to 115″, corresponding to spatial extents of 410 kpc. The extended emission is likely to be both unbeamed diffuse emission and beamed emission associated with relativistic bulk motion in jets. The spatial extents and luminosities of the extended emission are consistent with the unification scheme for active galactic nuclei, where BL Lac objects correspond to low-excitation radio galaxies with the jet axis aligned along the line of sight. While extended emission is detected around the majority of BL Lac objects, the median 144–1400 MHz spectral index and core dominance at 144 MHz indicate that the core component contributes ∼42% on average to the total low-frequency flux density. A stronger correlation was found between the 144 MHz core flux density and the γ-ray photon flux (r = 0.69) than between the 144 MHz extended flux density and the γ-ray photon flux (r = 0.42). This suggests that the radio-to-γ-ray connection weakens at low radio frequencies because the population of particles that give rise to the γ-ray flux are distinct from the electrons producing the diffuse synchrotron emission associated with spatially extended features.

We place the first constraints on binary planets and exomoons from Doppler monitoring of directly imaged exoplanets. We model radial velocity observations of HR 8799 b, c, and d from Ruffio et al. and determine upper limits on the

We achieve our tightest constraints on moons orbiting HR 8799c, where with 95% confidence we rule out out edge-on Jupiter-mass companions in periods shorter than 5 days and edge-on half-Jupiter-mass moons in periods shorter than 1 day. These radial velocity observations come from spectra with resolution 20 times lower than typical radial velocity instruments and were taken using a spectrograph that was designed before the first directly imaged exoplanet was discovered. Similar data sets from new and upcoming instruments will probe significantly lower exomoon masses.

Published: November 2021

Morphologic variability from 25 populations of Acer campestre L. in Bosnia and Herzegovina was analyzed. Morphometric structure of variability and between-population variability was performed based on 10 fruit-parameter characteristics and 19 leaf-parameter characteristics using multivariate statistical analysis. Results confirmed the separation of three submediterranean populations as a group in relation to other tested populations, from which the Banja Luka population is different. Measured leaf parameters were confirmed as a predominant carrier of the morphologic separation between populations. In other Acer species populations within A. monspessulanum and A. intermedium species are separated mainly by fruit and much less by leaf parameters. The southernmost submediterranean populations from Trebinje, Ljubuški, and Mostar regions have smaller leaf areas, which consequently places them within the same morphologic group; their variability is in tight connection with eco-geo-graphical factors, where the ecological distance is a much better predictor of morphological variability compared to geographical distance. The air temperature had the biggest influence on morphological variability regarding the highest in-between correlation. Achieved results may serve for the continuation of the research in other areas of Acer campestre to determine the interactive effect of ecological, geographical, climatic, and migrational factors on their morphologic population plasticity.

The bent-toed geckos of theCyrtodactylus pulchellusgroup are widely distributed along the Thai-Malay Peninsula. Although taxonomic and phylogenetic studies of this species group have been continuously conducted, only some populations from Thailand have been included, resulting in hidden diversity within this group. In this study, we used morphological and molecular data to clarify the taxonomic status and describe a new population from Tarutao Island, Satun Province, southern Thailand.Cyrtodactylus stellatussp. nov.can be distinguished from its congeners by the combination of the following morphological characters: body size; tuberculation; number of dark body bands, ventral scales, and femoroprecloacal pores in males; presence of precloacal pores in females; and scattered pattern on dorsum. Phylogenetic analyses of the mitochondrial ND2 gene recovered the new species as the sister species toC. astrum, with an uncorrected pairwise divergence of 9.78–12.37%.Cyrtodactylus stellatussp. nov.is currently only known from Tarutao Island, Thailand. The discovery of this species suggests that the diversity within theC. pulchellusgroup remains underestimated and future exploration of unsurveyed areas are needed to further the understanding of this group and its geographic range.
Imaginaires et rhétoriques de la mondialité au patrimoine culturel immatériel de l’UNESCO
Authors: Debarbieux Bernard
Published: November 2021

Le présent article se propose d’analyser comment des pratiques culturelles parfois dites mondialisées – le yoga, la fauconnerie, le tango, le flamenco et l’alpinisme – ont été promues, puis inscrites, au patrimoine culturel immatériel de l’UNESCO. Il étudie la rhétorique et les stratégies scalaires adoptées par les protagonistes de chacune des propositions, en s’arrêtant tout spécialement sur la mise en scène d’une forme de mondialité, revendiquée ou nuancée, pour arguer du bien-fondé de leur inscription. Il montre dans quelle mesure certaines ont été guidées par un souci de recentrage national ou régional (le flamenco, le tango, le yoga) quand d’autres ont cherché à souligner la dimension transnationale de la pratique et de la coopération interétatique (l’alpinisme, la fauconnerie). Il montre enfin comment la procédure d’inscription en pareil cas mobilise plusieurs imaginaires de la mondialité et que leur articulation joue un rôle décisif dans le succès d’une candidature.

Published: November 2021

BACKGROUND AND OBJECTIVE:

To investigate the effect of the coronavirus disease 2019 (COVID-19) lockdown on the presentation and management of acute, primary rhegmatogenous retinal detachment (RRD).

PATIENTS AND METHODS:

This was a single-center, consecutive case series with historic controls, examining patients during the COVID-19 “stay-at-home” order (March 24 to June 1, 2020), the subsequent reopening phase (June 1 to July 31, 2020), and corresponding preceding intervals (March 24 to July 31, 2016 to 2019).

RESULTS:

Despite a significant increase in patients presenting with macula-off RRD during the COVID-19 lockdown compared to the 2016 to 2019 timeframe (
P
= .03), the rate of single surgery anatomical success was similar between all groups (
P
= .66), as was final visual acuity (
P
= .61). No delays between presentation and surgical intervention were observed during the lockdown (
P
= .49).

CONCLUSIONS:

Despite the limitations of the COVID-19 lockdown, patients underwent surgery in a timely manner and achieved comparable visual outcomes to controls before COVID-19.

Impulsive hemivariational inequality for a class of history-dependent quasistatic frictional contact problems
Authors: Guo Furi , Wang Jinrong , Han Jiangfeng
Published: November 2021

This paper deals with a class of history-dependent frictional contact problem with the surface traction affected by the impulsive differential equation. The weak formulation of the contact problem is a history-dependent hemivariational inequality with the impulsive differential equation. By virtue of the surjectivity of multivalued pseudomonotone operator theorem and the Rothe method, existence and uniqueness results on the abstract impulsive differential hemivariational inequalities is established. In addition, we consider the stability of the solution to impulsive differential hemivariational inequalities in relation to perturbation data. Finally, the existence and uniqueness of weak solution to the contact problem is proved by means of abstract results.
La transferencia de tecnología en la Europa Latina: el papel de la Société Technique de l’Industrie du Gaz en France, 1895-1938
Authors: Martínez-López Alberte , Mirás Araujo Jesús
Published: November 2021

Francia, junto con Gran Bretaña, fue el país líder en el nacimiento y consolidación de la industria del gas. Desde mediados del siglo XIX este país desempeñó un papel clave en la difusión de la tecnología de producción de gas de hulla, especialmente en el área mediterránea, en donde concentró un gran volumen de inversión en el exterior. Entre los factores responsables de este proceso debe destacarse la presencia de ingenieros y diversas asociaciones profesionales. Entre estas últimas sobresale la Société Technique de l`Industrie du Gaz en France, una de las principales asociaciones gasistas a nivel internacional. Este organismo, constituido en el año 1874, aglutinaba a profesionales del sector, que actuaron como agentes que pilotaron la transferencia tecnológica internacional. El objetivo del trabajo es analizar la relevancia de la asociación en dicho proceso de difusión técnica, tanto en Francia como en el resto de la Europa latina (España, Italia y Portugal) desde finales del siglo XIX hasta la Segunda Guerra Mundial, empleando las actas de sus congresos como fuente principal.
