Lalangue et l’ombre du sonore : évidence ou négligence ?
Authors: Meynard André
Published: November 2023

D’évidence, pour nous qui usons de langues vocales dans nos interlocutions, lalangue s’inscrit dans le sonore. Cependant, n’y a-t-il pas à prêter attention à ce qui opère de lalangue pour des parlêtres qui, certes, ne perçoivent pas les fréquences acoustiques des langues vocales, mais se trouvent pulsionnellement poussés à prendre la parole dans des langues dites « signées » ? Réinventer la façon dont la psychanalyse peut durer lorsque le matériau langagier n’est plus vocal, nécessite ici une familiarisation de l’analyste au maniement de telles modalités du dit, afin de pouvoir suivre le vif du sujet qui sonne dans le dire. Les effets de division subjective structuraux, révélateurs de la marque signifiante, se font également entendre dans un tel matériau langagier. Surgit ainsi l’opérativité de lalangue et de ses brins visuels, gestuels et tactiles bien souvent négligés. La clinique analytique mène d’ailleurs à faire retour sur certains propos de J. Lacan évoquant avec pertinence ce « discours par des signes visuels » (ou « langage sur les doigts »). En faisant compter la portée heuristique de ces divers frayages et de plusieurs autres travaux analytiques, seront ici questionnées certaines négligences idéalisant indûment le sensoriel sonore dans l’abord de lalangue. Les répercussions d’une telle prise en compte sont considérables pour l’humain « affligé » du langage…
« Le football et le rapprochement des peuples » ou la Weltanschauung des premiers dirigeants de la FIFA (1904-1942)
Authors: Dietschy Paul
Published: November 2023

Les premiers dirigeants de la FIFA ont voulu bâtir un internationalisme dont les fondements sont l’État-nation représenté par une fédération ayant le monopole sur la pratique du football dans son pays. Très vite, le cas de l’empire austro-hongrois permet de mettre en pratique cette conception même si une exception est faite pour le Royaume-Uni. La Grande Guerre suspend les relations sportives internationales. Bien que les fédérations belge et britannique veuillent expulser au lendemain de la guerre la fédération allemande, l’internationalisme de la FIFA se teinte vite de pacifisme, notamment à la fin des années 1920. Encore européocentriste, l’organisation s’ouvre au monde et sa première Coupe du monde est organisée en Uruguay. Néanmoins, les années 1930 et les agressions fascistes mettent à l’épreuve son pacifisme et sa neutralité. Si elle doit se plier aux transformations territoriales de l’Europe, son comité exécutif parvient toutefois, sous la direction du président Jules Rimet, à conserver une neutralité bienveillante notamment pendant la Guerre d’Espagne.
Les sportifs argentins, « meilleurs ambassadeurs de la Nueva Argentina » (1946-1955)
Authors: Hémeury Lucie
Published: November 2023

Dès 1948, le président de la République argentine, Juan Perón, proclame que les sportifs sont les « meilleurs ambassadeurs du pays ». Cette déclaration devient un argument privilégié pour justifier le soutien gouvernemental accordé aux athlètes de haut niveau sous le péronisme. Cet article examine l’intégration progressive des sportifs au programme diplomatique du régime. Face à l’hostilité généralisée de la part de la communauté internationale, le gouvernement péroniste a recours au sport pour tenter de rompre son isolement et de redorer son image à l’extérieur. À travers l’exemple des délégations olympiques et la mise en place d’un système d’« amateurs d’État », cet article explore la transformation des athlètes en représentants de la nation et en promoteurs du péronisme, envoyés en mission à l’étranger.
Franchir la frontière de l’URSS et ne pas revenir. Les conditions de la politisation des défections d’athlètes
Authors: Dufraisse Sylvain
Published: November 2023

Dans le contexte de la Guerre froide, le monde du sport international est devenu un des théâtres de l’affrontement Est-Ouest. Les athlètes soviétiques font partie en URSS des privilégiés qui franchissent régulièrement les frontières de la patrie et le rideau de fer. Pour leurs adversaires, ils sont une cible de choix, hautement symbolique. Plus que les secrets qu’ils détiennent, en faire des transfuges permet de profiter de la forte médiatisation des compétitions sportives et de prouver les vices des régimes socialistes par la défection. En se centrant sur le cas de l’URSS, cet article examine les conditions de la politisation des défections d’athlètes. Il montre que si les défections restent rares, les méthodes choisies pour les éviter contribuent à renforcer l’idée que les citoyens soviétiques ne vivent pas librement.

Published: November 2023

Pyrolysis is a complex energy conversion reaction due to the multiple stages of the process, the interaction of kinetics, mass and heat transfer and thermodynamics. The feedstock, temperature, heating rate, residence time, and reactor design are only a few factors that might impact the final product during the pyrolysis process. This study focuses on the temperature analysis of pyrolysis with sheep manure as feedstock, which includes reactor, pipes and condenser. The examination of the temperature distribution within a pyrolysis system can contribute to the preservation of product quality, the maintenance of heat balance, and the enhancement of energy efficiency. Based on the analysis, the degradation temperature of sheep manure is between 210–500 ℃. Consequently, it is crucial to control the reactor temperature at a desirable temperature that aligns with the degradation temperature of sheep manure. To ensure optimal condensation and maximize bio-oil yield, it is also necessary to control the condenser temperature. This study aims to determine the characteristics of temperature changes in pyrolysis systems using atomic models. The atomic model was built in OpenModelica using the Modelica language. The atomic model was validated with experiment, and it was found that there was a significant difference in reactor temperature. Complex processes occur in the reactor where pyrolysis occurs and various factors can impact the temperature of the reaction. The temperature in the multistage condenser gradually decreases by 1–3 ℃. In the principle of condensation, this temperature drop is considered less than optimal because the cooling fluid in the pyrolysis condensation system is air coolant, which is entirely reliant on ambient temperature. The accuracy of the atomic model is evaluated using error analysis and the mean absolute percentage error (MAPE). A value of 13.6% was calculated using the MAPE. The atomic model can be applied because this value is still within the tolerance range.

Authors: Jin Yang , Li Wanxiang , Zhang Hongbing
Published: November 2023

A two-degree-of-freedom vehicle wheel-rail impact vibration system model is developed, and the equivalent impact stiffness and damping of the rail are fitted applying ABAQUS, taking into account the high and low irregularity generated by the welded joints of the rail. A wheel-rail periodic interface with fixed impact was selected as the Poincaré map, and the fourth-order Runge-Kutta numerical method with variable step size was used to solve the system response. The dynamic characteristics of the system are investigated using a combination of the Bifurcation diagram, Phase plane diagram, the Poincaré map, the Time-domain diagram and the Frequency-domain diagram. It is verified that the vehicle wheel-rail impact vibration system has Hopf bifurcation, Neimark-Sacker bifurcation, Period-doubling bifurcation and Boundary crisis, and there are rich and complex nonlinear dynamic behavior changes. The research on the bifurcation and chaos characteristics of vehicle wheel-rail impact vibration systems can provide a reference for improving the stability of vehicle operation in engineering practice as well as the prediction and control of chaos in vehicle vibration reduction design.
Some new inequalities for nonnegative matrices involving Schur product
Authors: Zhong Qin
Published: November 2023

In this study, we focused on the spectral radius of the Schur product. Two new types of the upper bound of $ \rho \left({M \circ N} \right) $, which is the spectral radius of the Schur product of two matrices $ M, N $ with nonnegative elements, were established using the Hölder inequality and eigenvalue inclusion theorem. In addition, the obtained new type upper bounds were compared with the classical conclusions. Numerical examples demonstrated that the new type of upper formulas improved the result of Johnson and Horn effectively in some cases, and were sharper than other existing results.

The implementation comparison between the Euler and trivial coupling schemes for achieving strong convergence
Authors: Alnafisah Yousef
Published: November 2023

This study aimed to develop efficient numerical techniques with the same accuracy level as exact solutions of stochastic differential equations (SDEs). The MATLAB program was used to find solutions for the Euler and trivial coupling methods. The results of these methods were then compared and analyzed. The results show that Euler and trivial coupling methods give the same strong convergence. Furthermore, we demonstrated that these methods achieve strong convergence with a standard order of one-half to the exact solution of the SDE. Moreover, the Euler method is characterized by its speed, ease of application and ability to find solutions through computer programs.
Unsteady-state turbulent flow field predictions with a convolutional autoencoder architecture
Authors: Abucide Álvaro , Portal Koldo , Fernandez-Gamiz Unai , Zulueta Ekaitz , Azurmendi Iker
Published: November 2023

Traditional numerical methods, such as computational fluid dynamics (CFD), demand large computational resources and memory for modeling fluid dynamic systems. Hence, deep learning (DL) and, specifically Convolutional Neural Networks (CNN) autoencoders have resulted in accurate tools to obtain approximations of the streamwise and vertical velocities and pressure fields, when stationary flows are considered. The novelty of this paper consists of predicting the future instants from an initial one with a CNN autoencoder architecture when an unsteady flow is considered. Two neural models are proposed: The former predicts the future instants on the basis of an initial sample and the latter approximates the initial sample. The inputs of the CNNs take the signed distance function (SDF) and the flow region channel (FRC), and, for the representation of the temporal evolution, the previous CFD sample is added. To increment the amount of training data of the second neural model, a data augmentation technique based on the similarity principle for fluid dynamics is implemented. As a result, low absolute error rates are obtained in the prediction of the first samples near the shapes surfaces. Even in the most advanced time instants, the prediction of the vortices zone is quite reliable. 62.12 and 9000 speed-up ratios are achieved by the predictions of the first and second neural models, respectively, compared to the computational cost regarded by the CFD simulations.

Authors: Qi Ziying , Li Lianzhong
Published: November 2023

In this paper, a new class of extended (2+1)-dimensional Ito equations is investigated for its group invariant solutions. The Lie symmetry method is employed to transform the nonlinear Ito equation into an ordinary differential equation. The general solution of the solvable linear differential equation with different parameters is obtained, and the plot of the solvable linear differential equation is given. A power series solution for the equation is then derived. Furthermore, a conservation law for the equation is constructed by utilizing a new Ibragimov conservation theorem.

(Dé)chiffrer l’animal sauvage. De l’administration numérique des collections vivantes en parcs zoologiques
Authors: Roustan Mélanie
Published: November 2023

Entre « pensionnaires » et « détenus », les animaux de zoo sont administrés par une pluralité de logiques de collection, de hiérarchisation du vivant et de représentation de la nature. Certains sont les descendants d’une époque où le goût pour l’exotique présidait au choix des spécimens. D’autres, ou les mêmes, ressortent des listes officielles des espèces menacées, qui indiquent une valeur de raréfaction relative et structurent la politique de conservation de la faune sauvage légitimant aujourd’hui l’existence des zoos. L’article se fonde sur une enquête ethnographique menée au Parc zoologique de Paris. Les inventaires et registres y guident, comme au musée, l’action des professionnels. à une échelle élargie, les bases de données mutualisées régissent les populations captives : déplacements et appariements – parfois « euthanasies » en fonction des patrimoines génétiques. Ainsi, numérisation, encodage et décodage des animaux sauvages se répondent.

Published: November 2023

This study is designed to evaluate students’ knowledge and perceptions about the online learning of pharmacy curricula in Iraq during the COVID-19 quarantine. A descriptive, cross-sectional study involving 278 pharmacy students was done between October 2020 and June 2021. About 42.44% preferred face–face lecturers over other modes of delivery for lectures in the pharmacy curriculum. Most participants preferred both active learning and face–face lectures. The results show that 72.66% of responders chose to stay at home as one of the privileges of e-learning. However, the main barriers that associated with e-learning were lack of patient involvement and some technical issues regarding IT equipment, (74.82%) and (62.23%), respectively. E-learning is seen as a lack of social presence, less social contact, and synchronization of connections. However, e-learning undoubtedly benefits students in several ways. Online learning is an essential podium for students to achieve their studies in periods of crisis.

Published: November 2023

Diabetes mellitus (DM) occurs when the body experiences insulin deficiency or is unable to use insulin appropriately, which increases the blood glucose levels over the threshold. Moringa oleifera leaf is a widely used and scientifically proven herbal medicine to treat DM. The demand for the development of new drugs has prompted in vitro, in vivo, and in silico studies of antidiabetic insulin-resistant activity. This study aims to conduct a comprehensive study of the types of flavonoid and nonflavonoid compounds that have antidiabetic activity in insulin resistance mellitus using in vitro, in vivo, and in silico approaches. The literature review was conducted in accordance with the offered reporting items for systematic review. Major bibliographic databases, i.e. Scopus, PubMed, and DOAJ, covering original articles about the aforementioned issues between January 1, 2011 and December 31, 2021 were used. In this study, 274 articles were retrieved, of which 4 were duplicates, and after the titles were read, only 108 were left for analysis. After the abstract screening, 32 articles were eligible for the literature review. The results exhibit that flavonoids, including quercetin and kaempferol, and nonflavonoids, including anthraquinone, cytogluside (glycoside), hemlock tannin, phenolic steroid, and 2-phenylchromenylium (anthocyanins), have potential insulin-resistant antidiabetic activity in vitro, in vivo, and in silico. This has broadened the research into the development of new drugs.

Authors: Lay Sammy Henry , Margono Anggraini , Bagio Dini Asrianti , Julianto Indah
Published: November 2023

Dental pulp is built by proteins that have various roles in the biological process of pulp, such as structural protein, regulation protein, and catalytic protein. L-arginine, an amino acid and one of the building blocks of proteins, regulates pro-inflammatory and anti-inflammatory activity. Therefore, L-arginine-based culture has potential to promote dental pulp regeneration. This study aimed to investigate the potential of L-arginine-based culture in improving the viability of human dental pulp stem cells (hDPSCs). We evaluated the viability of hDPSCs in culture media supplemented with different concentrations of L-arginine amino acid (250, 300, 350, and 400 µmol/L) and Dulbecco’s Modified Eagle Medium plus fetal bovine serum 10% (control) using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay after 24-h incubation time. Statistical analysis was conducted using a one-way analysis of variance and post hoc least significant difference test. In qualitative analysis, the 4´, 6-diamidino-2-phenylindole staining method was used. The evaluation has shown a significant result when 250, 300, and 350 μmol/L concentration of L-arginine amino acid culture media compared with control, and 400 μmol/L has the best result and was not significantly different with control toward viability of hDPSCs.

Published: November 2023

Efficacious use of antimicrobial agents (AMAs) is paramount to combat a wide range of infections, ensure patient safety, and reduce antimicrobial resistance. To assess the drug utilization patterns of AMAs in hospitalized patients with infectious diseases in a secondary care hospital. A prospective observational study was conducted for 6 months in the internal medicine department. Data were collected, antimicrobial prescription patterns were screened, and drug utilization was assessed using the anatomical therapeutic chemical/defined daily dose methodology. Furthermore, predictors of the prescription of multiple AMAs were also analyzed. A total of 146 patient case records were reviewed and 285 AMAs were prescribed during the study period with a mean patient age of 54.2 ± 24.4 years. The average number of antimicrobials administered per patient was 1.94 ± 0.94. Respiratory tract infection and urinary tract infection were the common indications, and penicillins were the most prescribed class of AMAs. Multivariate analysis showed that the presence of comorbidities (P < 0.05) and longer hospital stays (P < 0.0001) increased the likelihood of prescribing multiple AMAs. The study provides insight into the pattern of prescribing of AMAs which help to improve the quality of care. Prescribing AMAs by generics and from the hospital formulary list according to the recommendations of the World Health Organization is a good sign of clinical practice. The study signifies the need to continuously monitor AMAs to optimize drug therapy and enhance the quality of drug use in clinical practice.

Authors: Tripathy Girijanandan , Basra Sharanjit Singh , Anand Vembu , Ravishekar N Hiremath , Verma Vishal
Published: November 2023

Background:

Acute limb ischemia (ALI) can be defined as sudden deterioration in limb perfusion, often producing new or worsening symptomatology and usually threatening limb viability. The incidence of ALI is approximately 1.5 cases per 10,000 persons per year.

Objective:

The main objective of the study is to assess the spectrum of ALI and effective management options in a tertiary care center.

Methodology:

This was a retrospective and prospective observational study. All patients admitted in tertiary care center with ALI were included in this study. The medical records of patients admitted since last three years were collected retrospectively and the data of patients with ALI getting admitted during next one year was collected simultaneously. Patients who were included prospectively were followed for at least one month.

Results:

In the study period, we received 136 patients with 138 ALI (ALI presenting with 14 days = 95, ACLI = 17, ALI with delayed presentation = 26). Average age of patients was 47.4 years. 21 to 40 years age group made the largest cohort of 56 patients. 10.79% of the lower limb ischemia were female (15 out of 136). Among these categories, the outcomes depend upon the time of presentation (earlier presentation has the better outcomes in terms of limb salvage). The delayed presentation of ALI has poorer outcome of amputation whereas mortality rates are higher in ALI presenting early. Patency in ALI is better due to embolus. Outcome of ALI due to embolus are best followed by acute thromboembolic occlusion without pre-existing CLI. The worst outcomes in amputation are for ACLI when they present late. Etiology wise Cardio embolic group comprised as the commonest cause; High Altitude Thrombosis also is very significant in our setting. Class II B ischemia which is most surgically amenable, and the amputation rate is 20%.

Conclusion:

In our study, outcome of various modalities of management of ALI has been evaluated. Our study provided data which could be accessed to define the outcome and most amenable to any useful intervention affecting outcome in patients of limb ischemia. Revascularization in ALI is aimed not only to prevent amputation but also to limit the level of amputation which is a forgotten aspect of salvage procedure in lower extremity.

To Compare Gall Bladder Retrieval from Epigastric versus Umbilical Port in Laparoscopic Cholecystectomy: A Randomized Controlled Study
Authors: Vashisht Anshul , Routh Dronacharya , Kandari Arunjeet Kanakizhi , Rao Pankaj P.
Published: November 2023

Introduction:

Pain is the most frequent complaint following laparoscopic cholecystectomy and the main reason for staying overnight at hospital. The retrieval of gall bladder (GB), an important terminal event of laparoscopic cholecystectomy, has been reported as one of the factors affecting postoperative port-site pain due to tissue trauma at port site. This extraction of GB is usually done either from the epigastric or umbilical port as per the surgeon’s preference. We tried to compare the postoperative pain and ease of retrieval among epigastric and umbilical port retrieval.

Materials and Methods:

It was a randomized controlled trial at a tertiary care hospital over 2 years. A total of 70 participants were finally analyzed in the study. The participants were divided into 2 groups based on the port of retrieval. The postoperative pain and ease of retrieval were analyzed among the groups.

Results:

Mean postoperative port-site pain and ease of retrieval were significantly better with retrieval through umbilical port as compared with the epigastric port with P values of. 0013 and. 0023, respectively. However, time taken for retrieval was significantly less when done through epigastric port.

Conclusion:

This study thus recommends umbilical port to be used for retrieval of GB due to significantly lesser port-site pain and better ease of retrieval.

Published: November 2023

Sengon (Falcataria falcata (L.) Greuter & R. Rankin) plantations in Indonesia are threatened by attacks from Boktor stem borers and gall rust disease. Controlling pests and diseases is difficult; therefore, planting resistant trees obtained from tree selection programs is necessary. Currently, genomic breeding often incorporates GWAS, which uses thousands of SNP markers to identify markers with significant associations with the traits studied. This study aimed to bypass such expensive studies by identifying and developing SNP markers from sequences of putative resistance genes to Boktor stem borer and gall rust disease, identified from sengon transcriptomic data analysis. A total of 496,194 putative SNP sites were identified from transcriptomic sequences using the SAMtools and BFCtools programs, of which 119 SNP sites were associated with resistance genes. Of the 101 non-synonymous SNPs selected, only 12 were located in the conserved domain of each gene and were used for primer design. Of the 13 primers designed, only 10 were successfully amplified. Validation of 10 developed SNP markers on 100 sengon accessions using the HRM method confirmed a significant association between SNP markers and resistance traits, with a -log 10 (P-value) between 10.49 and 16.63. A few SNPs markers developed from putative resistance gene sequences are associated with resistance traits in sengon. Therefore, the SNP markers could be applied in selection programs for sengon trees resistant to Boktor stem borers and gall rust disease.

Published: November 2023

Actinomycetes are known to be a source of natural products and drugs. Gordonia terrae, an actinomycete pigment producer, shows potential in producing pigment with antimicrobial activity. This study aims to determine the antimicrobial activity of the active pigment fraction produced by the actinomycete G. terrae, assess the effects of the active pigment fraction on microbial cells, and identify the types of compounds present in the fraction. The pigment extract exhibited antimicrobial activity against Gram-positive bacteria and fungi. Specifically, it showed activity against Bacillus subtilis ATCC 6633, Staphylococcus aureus ATCC 25293, and Candida albicans ATCC 10231. Furthermore, the study evaluated the antimicrobial activities of the active fractions, revealed the active fraction had better antimicrobial activity than the crude extract. Scanning electron microscopy (SEM) confirmed that the active fraction of the pigment causes damage to B. subtilis ATCC 6633 cells, inhibits the formation of filaments in C. albicans ATCC 10231, and alters the normal shape of the cells. LC-MS/MS results showed that the active fraction contained several compounds known for their antimicrobial activity. Among the dominant compounds identified were cholestyramine, aminopregnane, and sphinganine. Thus, this study demonstrated that the orange pigment extract derived from G. terrae JSN1.9 exhibits promising antimicrobial activity.

Authors: Kamoru Lawal , Joseph Emmanuel
Published: November 2023

The safety of the patient is of highest importance during diagnostic imaging which uses various forms of ionizing radiations mainly photons (x-rays and gamma rays). Both the patient and personnel working in the diagnostic facility may be exposed to unintentional source of radiations during diagnostic imaging. This study was conducted at the Federal Medical Center, Katsina and General Amadi Rimi Specialist Hospital, Katsina to assess the shielding adequacy of the barriers required to attenuate the intensity of X-ray to recommended limit. The National Council on Radiation Protection and measurement (NCRP), Report No 147 was used to evaluate the shielding barriers of the radiographic rooms in the two facilities. Calculation was done using the number of patients (N), occupancy factor (T), Design dose limit (P) and the distance to the occupied area (controlled and uncontrolled area). The result shows that the room area meets the recommendation of Nigeria Nuclear Regulatory Agency (NNRA) of at least 16 m2 and the shielding requirement for the primary barrier is slightly higher than secondary barrier of each room. The calculated shielding requirement for the primary barrier of room I, room II and room III of Federal Medical Center, Katsina and room IV of General Amadi Rimi Specialist Hospital, Katsina are 0.59 mm, 0.46 mm, 0.36 mm and 0.48 mm respectively. The maximum calculated shielding requirement for the secondary barriers in room I, room II, and room III of Federal Medical Center, Katsina and room IV of General Amadi Rimi Specialist Hospital, Katsina are 0.55 mm, 0.48 mm, 0.63 mm and 0.48 mm respectively. The ratio of the calculated to current material thickness is less than one (<1) for all the rooms.This indicates that the shielding barriers in the facilities are adequate. Hence, can accommodate future increase in the number of patients examined in the diagnostic rooms per week.

Authors: Ahmad Nurul Atiqah , Sulaiman Zulkefly , Abdul Samad Mohd Yusoff , Rezaul Karim Sarker Mohammad , Salisu Monsuru Adekunle
Published: November 2023

The brown bast (BB) syndrome causes a 15-20% loss of annual rubber (Hevea brasiliensis) production in Malaysia, and no sustainable remedy has been developed yet. Initial investigation showed a macronutrients deficiency in the bark of affected plants compared to non-affected plants. Therefore, this study was undertaken to know the effect of spraying the deficient macronutrients in curing BB syndrome and increasing latex productivity. The treatments were selected by adjusting deficient nutrients, especially in N, K, and S, compared to healthy plants. The treatments consisted of 13 combinations of nutrient concentrations and a control (no application on healthy rubber trees). One liter of individual treatment per tree was applied on the trunk of BB-affected trees once a week for one month. Data on latex production was collected one week after the last application and continued for up to three months. The results showed that the treatment T9 (0.5% N, 0.8 mg/L K, and 0.2% S), in addition to other prescribed nutrients, made a 100% cure of BB syndrome after three weeks of application, and the nutrient contents of the bark of the affected plants appeared to be similar to the healthy plants. Applying these additional nutrients enhanced the latex production at the rate of 51.85 g/tapping/tree after two months of treatment application under the agro-ecosystem of FELCRA, Simpang Renggam, Johor, Malaysia. It is a new finding to 100% cure BB syndrome and to increase the latex productivity in sustaining the rubber industry in Malaysia.
