Authors: Castro Eder Alonso , Queiroz Eliziane Rodrigues de
Published: September 2020

O presente estudo se define por uma pesquisa qualitativa que visa conceituar a educação a distância- EAD em suas diferentes manifestações, assim como a utilização de atividades remotas no intuito de substituir aulas presenciais em virtude da epidemia do COVID - 19. Partiu-se da preocupação do uso incorreto da sigla EAD para designar qualquer atividade educacional a ser executada neste momento de isolamento social. A preocupação dos autores foi a de ouvir estudantes e docentes que estejam passando pela experiência das atividades não presenciais e perceber seus sentimentos e dificuldades neste momento singular que estamos vivendo. Nesse sentido, distribui-se, aleatoriamente, questionários que foram respondidos por estudantes e docentes e analisamos suas respostas como forma de resultado de nossa pesquisa. Dos dados mais curiosos da pesquisa vale citar as dificuldades de ambientação com a tecnologia, assim como as complicadas condições de organização de espaço e tempo para executar as atividades em ambiente domiciliar. Tais dificuldades foram relatadas tanto por estudantes quanto pelos docentes. Outro fato importante está na falta de planejamento e capacitação docente apropriada para execução de atividades não presenciais.

Published: September 2020

Dharma Andalas University is a change in form from the Dharma Andalas Higher School of Economics (STIE). Dharma Andalas University is one of the private universities in the city of Padang which is under the auspices of the Andalas Dharma Education Foundation (YPDA) which is directly fostered by the Andalas University alumni association. Dharma Andalas University is a private university so operational costs come from student tuition fees. Payment of tuition fees is an obligation of every student, considering that tuition fees are quite expensive, Dharma Andalas University provides relief for students to make tuition payments in installments. The purpose of this study is to assist the leadership in making a decision to pay installments using the Weighted Product method. In this study, the data processed is the data of students who apply for installment tuition payments at Dharma Andalas University. The data processing is to determine the criteria for each alternative by multiplying for attribute match reting, then rank with the attribute weight value which results in the vector value V, then the vector value V is ranked from the highest value to the lowest value where the highest value will be prioritized. Furthermore compared to the manual calculation method with a system that has been made, the results are the same with an accuracy rate of 100%, so that it can be recommended to the leadership to help make decisions about the payment of tuition installments.

Demam merupakan gejala yang sebagian besar terjadi pada semua penyakit dengan kondisi peningkatan suhu tubuh di atas normal yaitu 38°C yang umum terjadi pada balita. Penanganan demam menggunakan antipiretik perlu diperhatikan terkait kerasionalan penggunaannya. Adapun aspek kerasioanalan meliputi penilaian tepat indikasi, tepat pemilihan obat, tepat pasien, tepat dosis dan cara pemberian, serta waspada terhadap efek samping. Penanganan demam pada balita dan anak sangat tergantung pada peran orang tua khususnya ibu. Pendidikan, pengetahuan, dan ekonomi ibu yang berbeda akan mengakibatkan kerasionalan penggunaan obat antipiretik berbeda pula. Berdasarkan wawancara pendahuluan di Desa Pulau Semambu didapatkan data tingkat pengethuan masyarakat terhadap penggunaan obat antipieretik secara rasional masih rendah. Oleh karena itu diperlukan suatu penyuluhan terkait penggunaan obat antipiretik pada balita dan anak secara rasional di Desa Pulau Semambu Inderalaya agar didapatkan outcome terapi yang baik. Penyuluhan ini akan dimulai dengan pengisian pre test kuisioner, materi penyuluhan dan post test kuisioner untuk melihat pemahaman ibu. Dari hasil evaluasi nilai benar pretest dan post test yang telah diikuti oleh 30 ibu ini didapat adanya peningkatan jumlah nilai benar yaitu 80% (24 ibu), tetap 13,33% (4 ibu), dan penurunan 6,67% (2 ibu).
MEDIA PEMBELAJARAN BERBASIS VIDEO ANIMASI UNTUK MENINGKATKAN KOMPETENSI SISWA DI SMA NEGERI 4 PALEMBANG
Authors: Efendi Rusdi
Published: September 2020

Intisari— Kenyataan yang dijumpai guru dalam pembelajaran dewasa ini adalah rendahnya prestasi belajar siswa, kurangnya motivasi belajar siswa, serta kesulitan guru dalam menyampaikan materi pelajaran. Biasanya hal ini akan ditandai dengan adanya fakta bahwa guru dalam proses pembelajaran akan selalu menanyakan: Apakah ada kesulitan dalam proses pembelajaran? Apa penyebab kesulitan tersebut? Apakah kesulitan tersebut dapat diatasi dengan menerapkan media pembelajaran yang lebih menarik?. Dalam proses belajar mengajar, kehadiran media mempunyai arti yang cukup penting karena dalam kegiatan tersebut ketidakjelasan bahan yang disampaikan guru dapat dibantu dengan menghadirkan media sebagai perantara. Kerumitan bahan yang akan disampaikan kepada peserta didik dapat disederhanakan dengan bantuan media pembelajaran. Ada dua cara mengkomunikasikan yakni melalui pendengaran atau pengelihatan. Alat bantu (media) pembelajaran dapat membantu dalam kedua cara tersebut. Media dapat mewakili apa yang kurang mampu diucapkan guru melalui kata-kata atau kalimat tertentu. Dengan demikian siswa lebih mudah mencerna bahan apabila ada bantuan media pembelajaran.

A Systematic Review and Meta-Analysis of Local Administration of 1 Percent Metformin as an Adjunct to Scaling and Root Planning on Periodontal Intrabony Defects
Authors: Alqahtani Hussam M.
Published: September 2020

The Purpose: This systematic review conducted to assess the effectiveness of local administration of 1 % Metformin as an adjunct to scaling and root planing on periodontal intrabony defects.

Methods: Two independents reviewers searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and ClinicalTrials.gov.We included randomized controlled trials (RCTs) of local administration of 1% metformin interventions in patients with periodontal intrabony defect undergoing scaling and root planing as compared to local administration of placebo gel where periodontal parameters were evaluated. The Cochrane RoB tool was used to evaluate the risk of bias. Meta-analyses for the quantitative data were performed. We assessed the level of certainty for our outcomes using (GRADE) tool.

Results: Among the 1666 studies screened, two RCTs were included in the meta-analyses. The meta-analysis showed a statistically significant difference for all outcomes except the plaque index.Quantitative analyses showed a weighted mean difference (WMD) of1.17 mm (95% CI=1.01 to 1.34 mm, P<0.00001) for depth of periodontal intrabony defect; a WMD of 2.54 mm (95% CI=2.20 to 2.88 mm, P<0.00001) for clinical attachment level;a WMD of 2.01 mm (95%CI=1.68 to 2.33 mm, P<0.00001) for probing depth (PD);a WMD of 0.38 (95% CI=0.14 to 0.62, P = 0.002) for bleeding on probing (BOP); and a WMD of 0.00 mm (95% CI=−0.04 to 0.04 mm, P=0.95) for plaque index. There is moderate certainty of the evidence for all outcomes.

Conclusions: Local application of 1% metformin in patients with periodontal intrabony defect may improve the clinical and radiographic periodontal parameters. Future clinical trials are required to confirm the clinical benefits of a 1% metformin application as adjunctive to scaling and root planing in patients with periodontal intrabony defect.

Infiltration of the Mascagni Node is a Strong Prognostic Factor for Gall Bladder Cancer Discovered in Resected specimen.
Authors: Berkane Salah
Published: September 2020

Introduction: The infiltrative node is a strong prognostic indicator of survival in gallbladder cancer. The profile of the Mascagni ganglion (Ganglion of the neck of the gallbladder) has never been studied and taken into account for the form of histological discovery. The purpose of this retrospective study is to assess the impact of the Mascagni lymph node profile (GGM) and the prediction of the presence of residual tumor tissue after a histological discovery of gallbladder cancer.

Material and method: Forty-one patients were collected. Group A (No infiltrated Mascagni node) is made up of 15 patients while group B (infiltrated Mascagni node) is made up of 26 patients. Complementary secondary surgery was retained in 27 patients (65.8%) who underwent complimentary radical surgery in 16 (39%) of them and palliative surgery for 10 others (24,4%). Sixteen patients (39%) did not have secondary surgery. The mean time to reopen was 93.9 (48-166) in group A and 85.6 (21-230) days (p=0.5). Only 2 patients (13.3%) of group A had a residual tumor (carcinomatosis) and 100% of patients of group B presented this residual tumor with or without second surgery (p<0.001).

Result: No patient of group A had infiltrated lymph node even after second surgery while 92.3% (24/26) of group B had finally infiltrated lymph node (results of two interventions) (p<0.001). Survival is significantly higher in-group A than in-group B. with global five-year survival reaching 46.6% vs only 03.8%. Free survival is significantly higher for group A than group B (73.3% (11/15) vs 03.8% (3/26). The survival is also significantly higher for both cholecystectomy alone and radical secondary surgery with 62.5% (05/08) vs 00% (00/16) (p < 0.05) and 85.60% (06/07) vs 30% (03/10) respectively (p<0.01).

Conclusion: GGM is a strong prognostic factor for gall bladder cancer discovered on the resected specimens. It must be noted systematically on the histological reports and be taken into account before the secondary radical surgery.

Authors: Nasution Albert; Akhyar Hamonangan , Tanjung Qadri Fauzi
Published: September 2020

Spinal anesthesia was typically used for elective surgery and was associated with the incidence of hypotension and bradycardia due to sympathetic block. Bezold-Jarisch reflex (BJR) is a reflex that contributes to cause hypotension and bradycardia mediated by serotonin receptors (5-HT3). Ondansetron, a 5-HT3 receptor antagonist, is assumed to inhibit the effect of serotonin and BJR. To assess the effectiveness of ondansetron in preventing hypotension and bradycardia after spinal anesthesia. This study was an experimental study with a "posttest with control group" design conducted at Haji Adam Malik General Hospital and USU Hospital in February 2020 to June 2020. Seventy study subjects who underwent lower abdominal, gynecology, lower extremities under spinal anesthesia were selected by consecutive sampling and were divided into 2 groups. Group 1 received 4 mg ondansetron, while group 2 received 2 cc normal saline, both interventions were given 30 minutes before spinal anesthesia Baseline and minimum mean arterial pressure were higher in the ondansetron group at 97.07 ± 5.09 mmHg and 85.20 ± 6.48 mmHg compared to the control group (p-value <0.05). Hypotension was more common in the control group (51.43%) than in ondansetron group (20%) (p-value <0.05). The mean baseline and minimum heart rate were higher in the ondansetron group at 81,09 ± 9,62 bpm and 79.7 ± 8.75 bpm compared to the control group (p<0.05). The incidence of bradycardia was more common in the control group (17.1%) compared to the ondansetron group (2.9%) (pvalue <0.05). Ondansetron 4 mg, given intravenously, is effective in lowering the incidence of hypotension and bradycardia under spinal anesthesia

Corporate services are service providers. A good service company should give the best possible service in order to create its own satisfaction for customers. Therefore, there is a greet need for qualified human resources. A company’s success is based on it’s performance, if an employee’s performance is bad then it produces a bad company. This is where human resources are concerned. With the methods of Human Resources Scorecard and Analytical Hierarchy Process this can help to see if the company’s employee’s performance is good or not. On the method of Human Resources Scorecard are the four perspectives of financial perspectives, customer perspectives, internal business process perspectives, and learning & growth perspectives. The four perspectives have the strategy of objectivity, from the strategy of objectivity, the key performance indicator. Research result from the use of both method of human resources scorecard and analytical hierarchy process, show that the employee performance assessments in this company have increased from a 4,03 score which can mean good employee performance to 4,51 which can mean very good employee performance.

Concrete is a composite construction material plays a vital role in the construction of the nation’s infrastructure. The failure of the structure are mainly due to the failure of the concrete in beam, column joints.In recent days more technical researches are going on to avoid the beam-column joints failure. In this experiment we add the aramid fiber to check the behavior of beamcolumn joints and externally wrapped with aramid fiber was test to failure. Using an arrangement which transfer horizontal moment to the joints of the beam-column through two opposite cantilever moment arms.Aramid fiber is a class of synthetic fibers and heat resistant. They are fibers in which the strength of the chemical bond can be exploited due to the reason the chain molecules are highly oriented along the fiber axis. The experimental work consist of casting RC beam-column joints in controlled beam-column joints, design for torsion beamcolumn joints, and fully wrapped with aramid fiber beamcolumn joints each 3 specimen and curing this specimen for 7,14,28 days and testing this test specimen under “Loading Frame”.

An X-Ray Luminosity-dependent “Changing-look” Phenomenon in UGC 3223
Authors: Wang J. , Xu D. W. , Wei J. Y.
Published: September 2020

The nature of the rare “Changing-look” (CL) phenomenon in active galactic nuclei (AGNs) is still under debate. We present Swift/XRT and UVOT follow-up observations of UGC 3223, a newly discovered repeat CL-AGN with type transitions of S1.5 → S2 → S1.8 occurring in a period of about 30 yr. By comparing the values previously reported in the ROSAT All-sky Survey and in the second Swift-XRT Point Source catalog, we clearly find that the X-ray flux tightly follows the optical spectral transition, in which a spectral type closer to a Seyfert 1 type is associated with a higher X-ray flux. An invariable X-ray spectral shape is, however, found in the CL phenomenon of the object. An extremely low Eddington ratio of ∼2 × 10−4 can be obtained from the X-ray luminosity for its Seyfert 2 state, which suggests the disk-wind broad-line region model best explains the CL phenomenon. A variation of the total UV emission is not revealed when compared to the previous Galaxy Evolution Explorer NUV observation, since the UVOT images indicate that ∼90% UV emission comes from intensive star formation in the host galaxy.
Constraining Galactic Structure with the LISA White Dwarf Foreground
Authors: Breivik Katelyn , Mingarelli Chiara M. F. , Larson Shane L.
Published: September 2020

White dwarfs (WDs) comprise 95% of all stellar remnants, and are thus an excellent tracer of old stellar populations in the Milky Way. Current and planned telescopes are not able to directly probe the WD population in its entirety due to its inherently low luminosity. However, the Galactic population of double white dwarf binaries (DWDs) gives rise to a millihertz gravitational-wave foreground detectable by the Laser Interferometer Space Antenna (LISA). Here we show how characterizing the angular power of the WD foreground will enable probes of the Galactic structure in a novel way to determine whether the Galactic WD population traces the spatial distribution of young, bright stars, or traces a vertically heated spatial distribution associated with the Galaxy’s oldest stellar populations. We do this using a binary population synthesis study that incorporates different Galactic spatial distributions for the DWD population. We find that the level of anisotropy in the WD foreground’s angular power spectrum is dependent on the vertical scale height of the population, but show that multipole coefficients from the spherical harmonic decomposition must be considered individually because of LISA’s angular resolution. Finally, we show that LISA can probe the vertical scale height of the Galactic WD population with an accuracy of 300 pc, using the hexadecapole moment of the WD foreground.
Variability in Protoplanetary Nebulae: VII. Light-curve Studies of Five Medium-bright, Oxygen-rich, or Mixed-chemistry Post-AGB/Post-RGB Objects

Published: September 2020

We have monitored over a 10-year interval the light variations of five evolved stars with very large mid-infrared excesses. All five objects appear to have oxygen-rich or mixed oxygen-rich and carbon-rich chemistries. They all vary in light: four over a small range of ∼0.2 mag and the fifth over a larger range of ∼0.7 mag. Spectral types range from G2 to B0. Periodic pulsations are found for the first time in the three cooler ones, IRAS 18075–0924 (123 days), 19207+2023 (96 days), and 20136+1309 (142 days). No significant periodicity is found in the hotter ones, but they appear to vary on a shorter timescale of a few days or less. Two also show some evidence of longer-term periodic variations (∼4 yr). Three appear to be protoplanetary nebulae (PPNe), in the post-asymptotic giant branch (post-AGB) phase of stellar evolution. Their light variations are in general agreement with the relationships among temperature, pulsation period, and pulsation amplitude found in previously studied PPNe. The other two, however, appear to have too low a luminosity (1000–1500 L
⊙), based on Gaia distances, to be in the post-AGB phase. Instead, they appear to be Milky Way analogs of the recently identified class of dusty post-red giant branch (post-RGB) stars found in the Magellanic Clouds, which likely had their evolution interrupted by interaction with a binary companion. If this is the case, then these would be among the first dusty post-RGB objects identified in the the Milky Way.
Time Delay between Outer Heliosheath Crossing and Observation of Interstellar Neutral Atoms
Authors: Bzowski M. , Kubiak M. A.
Published: September 2020

In situ measurements of the heliospheric particle populations by the Voyager spacecraft can only be put in an appropriate context with remote-sensing observations of energetic and interstellar neutral atoms (ENAs and ISN, respectively) at 1 au when the time delay between the production and the observation times is taken into account. ENA times of flight from the production regions in the heliosheath are relatively easy to estimate because these atoms follow almost constant speed, force-free trajectories. For the ISN populations, dynamical and ballistic selection effects are important, and times of flight are much longer. We estimate these times for ISN He and H atoms observed by IBEX and in the future by IMAP using the WTPM model with synthesis method. We show that for the primary population atoms, the times of flight are on the order of three solar cycle periods, with a spread equivalent to one solar cycle. For the secondary populations, the times of flight are on the order of ten solar cycle periods, and during the past ten years of observations, IBEX has been collecting secondary He atoms produced in the outer heliosheath during almost the entire 19th century. ISN atoms penetrating the heliopause at the time of Voyager crossing will become gradually visible about 2027, during the planned IMAP observations. Hypothetical variations in the ISN flow in the Local Interstellar Medium are currently not detectable. Nevertheless, we expect steady-state heliosphere models used with appropriately averaged solar wind parameters to be suitable for understanding the ISN observations.

Breaking the silence: how shedding light on the bone-skipper fly Thyreophora cynophila (Diptera: Piophilidae) demonstrated it still has a large distribution area in the Pyrenees mountains, France
Authors: Azémar Frédéric , Cazaban Frédéric , Pelozuelo Laurent
Published: September 2020

Thyreophora cynophila (Panzer, 1798) is an iconic species of the European entomofauna. This winter-flying necrophagous fly was considered long extinct in Europe, before being discovered in Spain in 2010 and re-discovered in France in 2020, with a unique locality in Saint-Paul-de-Jarrat (Ariège, southern France).

After bringing this species to the attention of people that are active in nature during the winter, including hunters, skilled naturalists, nature lovers and professional naturalists, we gathered seven new occurrence data for this species at six locations on the French flanks of the Pyrenees mountains. Those data considerably extend the known distribution of the species in Europe and allows mapping the first approximate extent of occurrence for this species in France.

Published: September 2020

Caucasian rock lizards of the genus is a unique taxa, including both bisexual and parthenogenetic species. The parthenogenetic species have originated as a result of natural hybridisation between females and males of different bisexual species. The species involved in interspecific hybridisation are called parental. However, sympatric zones (SZ) of unisexual and bisexual rock lizards of the Caucasus are still poorly studied, although they are very important for understanding the role of hybrid individuals of different origin in reticulate evolution. This paper presents the location of the SZs of parthenogenetic and their parental bisexual rock lizards of the genusDarevskiain Armenia and adjacent territories of Georgia and Nagorno-Karabakh. We summarised the locations of the SZs identified from 1957 to the present, based on our field survey data gathered in 2018-2019 and records from publications and museum collections. This dataset includes 39 SZs of three types: SZ of parental bisexual species, SZ of parental species with unisexual species and SZ of the parthenogenetic species. For each zone, species composition, geographical and altitudinal distribution are presented. New records expand our knowledge of the geographical and altitudinal distribution of SZs in these species and provide additional data for understanding the mechanisms of reticulate evolution and hybridogeneous speciation in the past, present and future.

The new records, including geographical and altitudinal distributions of three types of SZs, are presented, which expand the previously-known list to 39 locations of contact zones for parthenogenetic and its bisexual parental species of rock lizards of the genusDarevskiain Armenia and the adjacent territories of Georgia and Nagorno-Karabakh.

The genus Colocasiomyia de Meijere (Diptera, Drosophilidae) is known to include 30 described and nearly 60 undescribed species classified into six species groups. Among these, the C. gigantea group of seven known species (two Southeast Asian and five Chinese) proved to be peculiar for its specificity on monsteroid (subfamily Monsteroideae, family Araceae) host plants. In this paper, two new species, C. todai Jiao & Gao, sp. nov. and C. liae Jiao & Gao, sp. nov., are described as members of the C. gigantea group with specimens collected from inflorescences of the monsteroid host species Rhaphidophora peepla (Roxb.) Schott and R. crassicaulis Engl. & Krause, respectively, in Yunnan, China. The two new species are delimitated, in comparison with all known species, based on not only morphological but also DNA barcode (partial sequence of the mitochondrial COI, i.e., cytochrome c oxydase subunit I, gene) data. A revised key to all the nine species of the C. gigantea species group is provided.
Errances : vers l’ awareness
Authors: Delacroix Jean-Marie
Published: September 2020

L’auteur présente l’« errance éclairée, enracinée, orientée, inspirée » comme un moyen nécessaire pour rencontrer l’inattendu, approfondir les concepts de la Gestalt et sortir de la pensée unique. Il s’appuie sur ses propres recherches hors des sentiers battus pour saisir le sens profond et le pouvoir hypnotique de l’awareness en relation. Il propose le concept de « ça et là » de la situation dans lequel flotteraient des « informations » errantes en quête d’apparition. Ce qui l’amène à réfléchir sur l’attitude intérieure du thérapeute lui permettant de les capter et de mettre de la cohérence dans ses découvertes.
Cohérence d’une formation ou la beauté du voile des mots
Authors: Gontier Alain
Published: September 2020

Le propos de l’auteur est de revisiter la formation de gestalt-thérapeute à la lumière du concept de cohérence. D’abord dans un axe vertical, celui de la transmission intergénérationnelle, ensuite dans une perspective plus horizontale, en proposant une distinction entre cohérence interne et cohérence externe. Cette distinction amènera l’auteur à soulever la question de la vérité et de l’efficience : quel rapport une théorie enseignée entretient-elle avec le « réel » ? qu’est-ce qui est transmis aux étudiants ? Et comment ?
“Errance”
Authors: Magnen Jean-Philippe
Published: September 2020

Au regard de son parcours qui oscille entre la « psy » et « le politique », l’auteur nous propose une exploration de l’interaction entre l’intime et le social au cœur de sa pratique de Gestalt-Thérapeute. En partant du constat que la théorie du champ « organisme-environnement » nous amène à ne pas dissocier les deux, il présente la relation patient-thérapeute se vivant et interagissant dans un cadre beaucoup plus large que l’unique relation intime à deux. Puis, à partir de cas cliniques, en s’appuyant sur ce postulat, il démontre comment, dans le champ vécu ainsi, cela le renvoie à la place qu’il accepte de donner aujourd’hui à l’inconnu dans l’accompagnement d’où tout peut émerger en assurant la sécurité du patient comme du cadre thérapeutique. Et que cela permet de vagabonder sur un chemin dont on ne connaît pas, ni l’un ni l’autre, la destination. Cet espace qui s’ouvre permet alors véritablement l’acceptation d’une co-errance propre à la posture du gestalt-thérapeute.
Jeux d’introjection dans ma clinique
Authors: Storaï Anne-Claire
Published: September 2020

Extrait d’un mémoire de formation de Gestalt-thérapeute, cet article explore un cas de violence traumatique à la lumière du concept d’introjection. Un certain nombre de séances avec la même patiente, Eva, sont analysées. L’auteur utilisera comme outils la psychotraumatologie, puis la posture de champ, pour donner sens aux processus à l’œuvre. Pas à pas, la figure qui se dessine est celle de l’irruption de la violence dans la relation thérapeutique. Et avec elle émerge la problématique : comment transformer les conditions pour que la rencontre soit supportable et génératrice de nouveauté ?
Crise de l’archipel culturel

Une certaine idée de la France
Authors: Bourlanges Jean-Louis
Published: September 2020

L’action du général de Gaulle est déterminée par une certitude et portée par une conviction. La certitude, c’est que les États nationaux sont, en dernier ressort, les acteurs indépassables de la vie internationale et qu’ils sont par essence inaltérables, insécables et indissolubles. La conviction, c’est que la France a, dans ce concert des nations, vocation à jouer les premiers rôles et à retrouver par le verbe et par l’exemple la position hégémonique qu’elle a accidentellement perdue il y a deux siècles. La combinaison de cette rigidité et de cette chimère a fini par enfermer dans une impasse la démarche héroïque du fondateur de la France libre.
La mystique constitutionnelle gaullienne : l’ombre portée du Général
Authors: Thiers Éric
Published: September 2020

La V e République est fondée sur la mystique constitutionnelle gaullienne. Sa finalité ultime est la pérennité de la nation française. Le peuple régulièrement consulté doit y tenir une place centrale. À la tête de l’État, le président de la République doit fixer la voie et, comme dans un organisme complexe, chaque institution doit exercer sa fonction propre, en évitant la confusion des pouvoirs. L’évolution du texte constitutionnel, des mœurs et pratiques politiques, et plus encore de la société dans ses structures et aspirations, a conduit à la dégradation de cette mystique. Pourtant, l’imaginaire constitutionnel gaullien pèse encore sur les perceptions et les comportements, en décalage avec la réalité politique contemporaine. Peut-on s’accommoder d’une telle discordance ?
La France et ses colonies
Authors: Turpin Frédéric
Published: September 2020

Charles de Gaulle a toujours considéré le processus historique de la colonisation à l’aune de l’intérêt supérieur de la France, qui ne pouvait pas être figé dans ses modalités. Considérant, au seuil des années 1960, qu’il était utile pour la France de décoloniser, il y a procédé avec pour objectif de pérenniser les anciens liens sous la forme d’une politique de coopération franco-africaine. Cinquante ans après la mort du Général, la déclinaison africaine de ce programme de puissance est-elle encore d’actualité ?
Quelle armée pour quelle défense ?
Authors: Vaïsse Maurice
Published: September 2020

La politique militaire gaullienne est le fruit de la riche expérience du Général. Elle est aussi le produit d’une combinaison entre les contraintes (guerre froide et guerre d’Algérie) et la volonté du chef de l’État de sortir de l’intégration atlantique et de disposer de l’arme nucléaire, instrument politique et diplomatique au service de l’indépendance nationale.
Charles de Gaulle, le communicant
Authors: Delporte Christian
Published: September 2020

De Gaulle présente un modèle accompli de communication contrôlée, ritualisée, personnalisée, dont l’objectif stratégique est à la fois la mise en place d’un dialogue direct avec les Français et la construction d’un imaginaire collectif de la V e République. Efficace pendant la crise algérienne, la communication gaullienne nécessite, aux temps plus ordinaires, des adaptations, pas toujours comprises et acceptées par le Général. Reste que le modèle imprime durablement sa marque sur la communication présidentielle.
Identification of degradation products of aflatoxin B1 and B2 resulting after their biodetoxification by aqueous extracts ofAcacia nilotica

Published: September 2020

Contamination of food and feed items with mycotoxins causes extensive economic damage. It is therefore important to explore environmentally friendly approaches to manage these toxins with less drawbacks. Phytochemicals can provide a safe alternative to synthetic chemicals. This study was designed to investigate the detoxification potential of water-based extracts ofAcacia nilotica against aflatoxins B1 and B2. First trials were carried out to standardise temperature, pH and incubation time for biodetoxification in spiked maize. A significant percentage of detoxification was observed under all tested conditions, showing an increasing detoxifying potential with an increase in all three parameters. Leaf extract was found to be more effective than shoot extract. Leaf extract resulted in 86-90% detoxification of both aflatoxin B1 and B2 when incubated for 72 h at 60 °C and pH 10. To avoid the detrimental effects of very high temperature and pH, experiments on spiked maize were conducted at 30 °C and pH 8. A significant detoxification of 82-83% was recorded during trials with spiked maize. MS/MS analyses showed conversion of aflatoxins B1 into seven and aflatoxins B2 into two new compounds. Most of the compounds were formed due to the removal of the double bond in the terminal furan ring and modification of the lactone group, indicating less toxicity as compared to the parent compounds. Decontamination and reduction in toxicity of treated aflatoxins was corroborated by a brine shrimps bioassay.
Mobile Ad Hoc Networks Security Enhancement With Trust Management
Authors: Sarbhukan Vaishali Vilas , Ragha Lata
Published: September 2020

The mobility and scalability brought by wireless networks made it possible in many applications. In MANET, discovering the stable, secure, and reliable routes is a challenging research problem due to the open nature of wireless communications. In Zhexiong Wei Routing Trust scheme (ZWRT), Bayesian approach and Dempster Shafer theory is used to evaluate more realistic trust value. Mohamed et al proposed Establishing STAble and Reliable Routes (ESTAR) system in heterogeneous multihop wireless networks. The above existing methods failed to solve the complete problem of information loss in MANETs. There are several other reasons due to which the information may loss in MANETS, such as mobility and congestion of mobile nodes. Therefore, the novel Enhanced Trust-based Secure Routing (ETSR) scheme is presented to deliver stable, reliable, and secure data communication in MANETs. The simulation results demonstrate that ETSR routing protocol improve QoS performance as compared to state-of-the-art techniques.
