Servitude et mobilité paysanne : les origines de la «Remença» catalane (XIe-XIIIe siècle)
Authors: To Figueras Lluis
Published: March 2023

Histoire du rachat (en catalan «remença»), une caractéristique majeure de la servitude catalane, à partir des premières chartes qui en attestent le paiement, depuis 1128, dans le diocèse de Gérone. Les chartes de rachat sont un document requis pour pouvoir quitter une seigneurie et s’installer dans une autre et son succès est dû en grande partie au fait qu’elles étaient réclamées par les seigneurs d’accueil. Mais l’exigence du rachat n’était pas destinée à retenir les paysans voulant partir ; elle était surtout un instrument pour faire face à une mobilité paysanne accrue dans un contexte de multiplicité des seigneuries et d’essor des villes nouvelles. Les seigneurs des villes ont parfois signé des accords avec leurs voisins pour bien encadrer les transferts de population. Les rois qui avaient aussi exigé des rachats dans leurs domaines sont parfois tentés d’encourager leurs villes avec des exemptions du rachat. Finalement, en 1283, le roi signe son accord formel à ne pas accepter sur ses domaines d’hommes qui n’auraient pas payé leur rachat.
Respublica et droit dans la Rome républicaine
Authors: Moatti Claudia
Published: March 2023

L’article retrace l’évolution sémantique, au dernier siècle avant notre ère, de respublica, l’un des termes par lesquels les Romains désignaient leur communauté. La première partie rappelle son acception traditionnelle, qui est patrimoniale et politique : une respublica est un espace où des «choses» sont en partage, une unité plurielle, un tout doté d’institutions particulières. La deuxième partie se propose d’expliquer la définition ramassée qu’en donne Cicéron – res publica est res populi –, et souligne le déplacement de l’accent de la res vers la «souveraineté» du peuple et le seul lien de droit. L’analyse approfondit plus particulièrement la comparaison insistante que mène Cicéron avec le modèle de la societas de droit privé, pour mieux penser la spécificité du politique et l’universalité de Rome. Dans la conclusion, sont formulées quelques hypothèses sur les développements impériaux de la notion.
La funzione della memoria nella definizione dell’identità religiosa in comunità monastiche dell’Italia centrale (secoli XI e XII)

Umberto LONGO, La funzione della memoria nella definizione dell’identità religiosa in comunità monastiche dell’Italia centrale (secoli XI e XII), p. 213-233. I due esempi ritenuti, l’abbazia di Santa Maria di Farfa e l’eremo di Fonte Avellana, permettono, attraverso i molteplici registri e i differenti scopi utilizzati per i processi di rielaborazione della memoria delle origini, di fare luce sui meccanismi e le dinamiche che soggiacciono alla necessità di rimemorazione. La ricostruzione delle origini riflette fedelmente il patrimonio spirituale e ideologico e lo specifico delle comunità. È un processo al quale concorrono una pluralità di scritti nei quali si registra una labilità e flessibilità di confini tra i generi letterari. È possibile rintracciare una volontà di evidenziare tali testi anche nei modi di conservazione nei criteri editoriali e di raccolta : l’importanza connessa ai testi dedicati alla codificazione del la memoria delle origini viene posta in evidenza anche materialmente, codicologicamente, mediante l’impiego di veri e propri criteri editoriali nella disposizione dei testi ritenuti fondamentali e la loro inserzione in codici di particolare rilievo e pregio.
Nuovi dati riguardanti la ceramica di età islamica nella Sicilia orientale
Authors: Arcifa Lucia
Published: March 2023

L’analisi di nuovi contesti archeologici e la rivisitazione di vecchi saggi di scavo consente di proporre alcune osservazioni relative alle produzioni ceramiche in Sicilia orientale tra IX secolo e età normanna. In particolare, si individua nella pentola da fuoco a superficie striata «tipo Rocchicella » un fossile guida per gli strati di IX secolo, che sollecita nuove riflessioni sul grado di innovazione delle produzioni altomedievali a confronto con la tradizione tardo antica e bizantina. Il confronto tra contesti coevi provenienti da differenti aree (Val di Noto e Val Demone) pone in evidenza l’esistenza di tradizioni artigianali differenziate, specchio delle più ampie differenze culturali e dei diversi contatti che la Sicilia nord orientale mantiene con le aree dell’Impero bizantino : è il caso della ceramica dipinta a bande, fin qui scarsamente attestata in Sicilia, presente, invece, a Taormina con percentuali elevate, che trova precisi paralleli con l’area calabrese e pugliese.
Un idéal nobiliaire dans la Savoie du XVe siècle : la Chronique de la Maison de Challant
Authors: Castelnuovo Guido
Published: March 2023

Au travers d’une lecture approfondie de la seule chronique aristocratique – et non princière – qui nous soit parvenue du Moyen Âge savoyard, cet article voudrait s’efforcer de reconstruire, sur plusieurs niveaux, les critères, les caractères et les modalités de l’autoconscience aristocratique au XVe siècle dans un contexte princier et rural. L’acteur protagoniste de cette oeuvre, tant historique que littéraire, est un puissant lignage seigneurial de la Vallée d’Aoste, l’un des bailliages qui composent le du ché de Savoie. Il s’agit des seigneurs de Challant et tout particulièrement de l’un d’entre eux, Jacques, le deuxième comte de Challant, décédé en 1459. En suivant le fil de la chronique dédiée à son jeune fils, les différents prismes de l’identité nobiliaire se précisent peu à peu : le lignage, ses solidarités et ses conflits internes ; la force des modèles seigneuriaux et chevaleresques ; l’importance du contexte religieux et ecclésiastique ; la place des femmes, vue à travers deux exemples de vertus féminines typiques de cette fin du Moyen Âge ; le rôle croissant joué par le service princier, à la cour et au sein de l’administration savoyarde. Bref, l’étude de cette chronique est un bon moyen pour passer en revue toute la complexité d’une palette nobiliaire aussi typique que raffinée.
Le rôle des provinces d’Occident dans l’approvisionnement de Constantinople (618-717) : témoignages numismatique et sigillographique
Authors: Prigent Vivien
Published: March 2023

L’article vise à mettre en lumière le rôle fondamental joué par la province de Sicile dans le ravitaillement de Constantinople au lendemain de la perte de l’Égypte, arrachée à l’empire byzantin par les forces sassanides puis arabes. Après une tentative pour réévaluer les besoins annonaires de la ville au VIIe siècle, une approche nouvelle du problème, fondée sur l’examen des sources numismatiques, propose une relecture d’un phénomène mal compris : la circulation de monnaies contremarquées dans l’île sous le règne d’Héraclius. Loin de constituer un pis-aller à l’effondrement de la production monétaire par la réaffirmation du cours légal des vieilles pièces encore aux mains de la population de l’île, ces monnaies témoignent d’un afflux massif de numéraire venu de la capitale. La chronologie du phénomène correspondant aux dix années de la première occupation de l’Égypte, on envisage que ces envois soient à mettre en relation avec une politique d’achat de blés à grande échelle. Une seconde source jusqu’ici négligée, les sceaux du kommerkion Sikèlias, permet de mettre en lumière l’organisation d’un système de ventes forcées de blé au profit de l’État dès le milieu du siècle, au moment où les sources pontificales dénoncent la mise en place d’un système de corvées maritimes frappant les populations d’Italie du Sud et d’Afrique. On y voit l’organisation d’un système de fret censé assurer le ravitaillement de la capitale.
Des peintures pré-iconoclastes en Terre d’Otrante
Authors: Jacob André , Berger Philippe
Published: March 2023

L’église S. Pietro de Crepacore, près de Torre Santa Susanna (prov. de Brindisi), a été récemment fouillée et restaurée par les soins de la Soprintendenza per i beni archeologici della Puglia. Ainsi sont apparus les restes d’une importante décoration picturale dont les éléments les plus anciens ont été datés par les chercheurs qui s’y sont intéressés soit de la fin du IXe ou du début du Xe siècle (G. Lavermicocca, M. Falla Castelfranchi), soit de la fin du Xe ou du début du XIe siècle (L. Safran). Mais l’analyse iconographique et stylistique des fresques, tout à fait inattendues dans le contexte local, et l’étude paléographique, anthroponymique et philologique de l’inscription dédicatoire imposent de remonter jusqu’à l’époque de la construction de l’édifice, au début du VIIe siècle, bien avant la crise iconoclaste.
Au miroir des choses familières : les correspondances humanistes au début du XVe siècle
Authors: Revest Clémence
Published: March 2023

Au cours des premières décennies du XVe siècle, les humanistes italiens ont posé les fondements du genre de la correspondance, imposant un modèle littéraire spécifique d’épistolographie. La constitution de ces recueils de lettres est alors loin de s’opérer selon un processus uniforme, ce qui constitue l’une des difficultés majeures de l’étude. Il est cependant possible de distinguer, au sein de ce foisonnement, les contours d’un certain nombre d’évolutions signifiantes pour l’histoire de l’émergence de l’humanisme. La genèse complexe de cette écriture de soi passe par la lente construction d’un programme normatif, révélateur des enjeux identitaires que revêt alors l’usage de la langue latine. L’édification de ce modèle permet aux humanistes de mettre en place les conditions d’un échange savant fondé sur la reconnaissance d’une altérité partagée. Enfin, les correspondances, entre mines d’informations et discours glorieux, s’apparentent à un récit des origines, à la fois exceptionnellement précis et consciemment reconstruit.

Published: March 2023

Purpose : The purpose of this study is to explore the essential structure and meaning of the in-depth experience of nurses caring for COVID-19 patients, and to provide basic data for preparing a holistic response strategy in the event of a new infectious disease in the future. Methods : This is a qualitative study conducted using in-depth interviews with 10 nurses in charge of COVID-19 patients and analyzed using the Colaizzi analysis method(1978). Results : As a result of the study, 158 meaningful statements, 4 topic groups, and 11 topics were derived about the experiences of nurses caring for COVID-19 patients. The subjects discovered that the experiences of nurses caring for critically ill patients in unfamiliar environments, such as COVID-19 isolation wards and environments with insufficient response guidelines, were a new dimension that was different from nursing patients with infectious diseases in the existing nursing environment. Conclusion : This study looked at the role of nurses who were pivotal in overcoming the epidemic of new infectious diseases by exploring the experiences of front-line nurses in crisis situations of emerging infectious diseases, and analyzed and structured their experiences as a whole.

Published: March 2023

The problem of water scarcity is not a transient issue, but to solve it has been a long lasting endeavor for humanity. Many human societies have tried diverse solutions to solve this problem and one of them was to efficiently move water for the subsistence of all people. For this purpose, civil and agricultural engineers seek to find novel ways to conduct water as close as possible to where it is needed, e.g., cultivated fields and water supply reservoirs, or to build up infrastructure to greatly reduce the immense problem of floods generated by high intensity rains. The main goal of this paper is to determine the water specific energies occurring in critical, subcritical and supercritical flow regimes, by means of a prototype rectangular section channel operation. Application of Bernoulli´s equation for uniform flow conditions is the adopted methodology. As final conclusions we can state that development of new channel prototypes facilitates the experimentation of fluids, allowing to a great extent the stabilization of flow, thus, optimizing the measurement of different types of key water variables.

Published: March 2023

The objective of this research is to evaluate the design of a pair of spur gears and another analogous pair with a contact ratio of less than unity. Considering two pairs of normalized gears with equal diametral pitches and pressure angles, as well as equal pitch radii in their driving gears and equal pitch radii in their driven gears. For the first pair of gears with normalized tooth numbers, the contact ratio greater than unity es obtained. For the second pair of gears, the number of teeth is proportionally reduced, consequently obtaining a contact ratio of less than one. For both pairs, the maximum von Mises stresses are obtained using the finite element method. The pairs are compared qualitatively and quantitatively. This work contributes with novel elements of judgment for a better decision making of the industrialists interested in reducing the problems of normalized spur gears such as noise, abrasive wear, adhesive wear, temperature, and efforts induced by the overlapping relationship between coupled teeth; proposing them a practical solution that will open new avenues of research.

obtain the modal frequencies of polymeric composite materials reinforced with unidirectional fibers (glass fiber and epoxy resin) for possible aeronautical applications. The objective of this study is to compare the behavior of an isotropic material with an orthotropic one. This comparison is to observe the influence of the material properties on its performance under dynamic conditions, where the modal frequencies of a material can directly affect the performance of each element of a structure. The first case describes the numerical and experimental identification of the modal frequencies of an isotropic material (6065 T5 aluminum). The second case study is presented to show how this methodology is adapted to the composite material. The experimental results are obtained by applying the impact hammer testing method. The comparison provides new insights into the modal behavior of vibrations in composite materials. A significant finding of this work is to provide a detailed analysis of the behavior of a unidirectional composite material in terms of the fiber’s orientation. Then, this work would be established the fundamentals of the composite material performance for rotative elements applications.
Concepciones sobre la Competencia Comunicativa Intercultural en la formación de docentes de inglés como lengua extranjera: un estudio de caso en la Carrera de Lengua y Literatura Inglesa de la Universidad de Cuenca
Authors:   , Rodas Pacheco Fabián Darío
Published: March 2023

Por mucho tiempo se han realizado varias investigaciones sobre el rol que desempeñan los docentes en diferentes áreas del conocimiento, así como las decisiones que ellos toman para llevar a cabo su práctica diaria. Dichas investigaciones han tenido como finalidad encontrar explicaciones que permitan interpretar su pensamiento y la relevancia que tienen sus concepciones y creencias al momento de llevar a cabo el proceso de enseñanza-aprendizaje (Chacón, 2015). Con estos antecedentes, el objetivo de esta tesis doctoral es validar la hipótesis de que tanto estudiantes como docentes de la Carrera de Lengua y Literatura Inglesa de la Facultad de Filosofía, Letras y Ciencias de la Educación de la Universidad de Cuenca no tienen una concepción clara sobre la Competencia Comunicativa Intercultural. La muestra de este estudio está conformada por 72 estudiantes y 12 profesores y, para su desarrollo, se ha aplicado la metodología mixta -cuantitativa/cualitativa-; los instrumentos de investigación usados son un cuestionario, entrevistas semiestructuradas y cuatro grupos focales. Con respecto al análisis de los datos, los paquetes informáticos son Excel, SPSS 22 y ATLAS. ti 7. En cuanto a los resultados, se observa en los participantes una escasa familiarización con el tema de la Competencia Comunicativa Intercultural. Se demuestra, sin embargo, un especial interés de implementarla en su práctica docente diaria y la necesidad del empleo de estrategias para tales fines. También se pone de manifiesto la necesidad de una capacitación permanente para poder llevarlas a cabo adecuadamente.

Determinants of Low Birth Weight Newborns in Indonesia: Literature Review
Authors: Rachmawati Reza , Yuliani Nur Rohma
Published: March 2023

LBW is a health problem that requires special attention in various countries, especially in developing countries with low socio-economic conditions. LBW has a greater risk of experiencing morbidity and mortality than babies born with normal weight. Factors that affect low birth weight (LBW) are teenage pregnancy, preeclampsia, anemia, and ANC visits. LBW is also one of the factors that can cause babies to die before reaching the age of 1 year. The purpose of this systematic literature review is to analyze the relationship between maternal age, preeclampsia, anemia, and ANC visits to determine the cause of LBW so that it can suppress IMR. Using the Critical Appraisal Skills Program (CASP) method with data sources obtained from PubMed, Google Scholar, and Research Gate, there are 145 articles reviewed. Inclusion criteria were (1) Teenage pregnancy, infant; (2) the incidence of LBW; (3) Factors influencing the incidence of LBW; (4) Full text; (5) Articles published from 2017 to 2021; and (6) national journals. There are 5 articles that meet the inclusion criteria. The results of this literature review are the factors that affect low birth weight (LBW), namely Teen Pregnancy, Preeclampsia, Anemia, and ANC visits.
FeelPen: A Haptic Stylus Displaying Multimodal Texture Feels on Touchscreens
Authors: Kodak Bence Levent , Vardar Yasemin
Published: March 2023

The ever-emerging mobile market induced a blooming interest in stylus-based interactions. Most state-of-the-art styluses either provide no haptic feedback or only deliver one type of sensation, such as vibration or skin stretch. Improving these devices with display abilities of a palette of tactile feels can pave the way for rendering realistic surface sensations, resulting in more natural virtual experiences. However, integrating necessary actuators and sensors while keeping the compact form factor of a stylus for comfortable user interactions challenges their design. Consequently, it limits the scientific knowledge of relevant parameters for rendering compelling artificial textures for stylus-based interactions. Here, we developed FeelPen, a haptic stylus that can display multimodal texture properties (compliance, roughness, friction, and temperature) on touchscreens. We created a set of artificial textures and conducted a user study in which human participants rated these textures based on various perceptual adjectives describing their haptic properties. Afterward, we extracted the dominant perceptual dimensions of these textures using the semantic differential method. Our results revealed four major tactile dimensions, with the first two related to surface textural properties, and the third and fourth dimensions linked to material softness and coldness, respectively. Our unique design and experimental results have the potential to open new perspectives for stylus-based interactions on future touchscreens.
Multidimensional Hosting Capacity Region in Dutch MV Grid Congestion Management
Authors: Gong Sicheng , Cuk Vladimir , Cobben Sjef
Published: March 2023

The hosting capacity determines the grid ability to host integrated installations, where mutual-limitations among points of connection (POCs) are important and formulate a combinational feasible region. Intended to assess such interaction for region determination, this paper proposes a multidimensional hosting capacity region derivation scheme in a radial grid. As this scheme can be designed conservative, it earns more industrial acceptance from a risk-averse perspective. This multidimensional region not only exploits grid power delivery potential, but also benefits for making grid congestion management decisions. A simulative 10.5kV dutch grid case has been tested accordingly. Corresponding results revealed that the region conservative property is guaranteed. In the given case study, compared to the original hosting capacity concept, the region hypervolume gain ratio keeps higher than 1.94. With proper measure selection, the estimated region occupation ratio can keep up to 92.50% and the congestion management decision computation time can be reduced by 58.0% in respect to that in the monolithic model. Both the effectiveness of proposed scheme and the concept benefit in grid congestion management are successfully verified.

Published: March 2023

This work introduces an open-source hardware and software expansion for digital microfluidics (DMF) devices that integrates programmatic temperature and magnetic control. Our aim was to create a versatile, modular, extension that may aid in biomedical applications and has proven potential for use in bacteriophage research. To achieve this, we developed an accessible DMF device extension called PhageBox.

PhageBox incorporates temperature and magnetic control modules at the hardware level. At the software level, it is controlled by embedded software that includes a unique model for bio-protocol programming and a graphical user interface for visual feedback and operation of the device. We evaluated PhageBox's effectiveness in biomedical applications using functional testing and validated the temperature control using thermography, achieving a range of +/-0.2 Celsius. The electromagnets produced a magnetic force of 15 milliTesla, which precisely immobilized magnetic beads.

Furthermore, we demonstrate the potential of PhageBox in bacteriophage research through three initial proof of principle protocols: (1) a universal framework for PCR, (2) T7 bacteriophage restriction enzyme digestion, and (3) the concentration of PhiX174 RF genomic DNA. Overall, our study presents an open-source solution for DMF devices to integrate temperature regulation and magnetism, facilitating various applications in biomedical research and bacteriophage studies.

Generalized Sparse Regression Codes for Short Block Lengths
Authors: Kumar Sinha Madhusudan , kannu arun pachai
Published: March 2023

Sparse Regression Code (SPARC) connects the sparse signal recovery framework with the error control coding techniques. In this paper, we focus on improving the block error performance of SPARC in short block length regime over the AWGN channel. Towards that, we introduce suitable candidates for dictionary matrices in real and complex fields using Gold sequences and mutually unbiased bases (MUB). We propose two generalizations of SPARC (GSPARC), develop a greedy decoder called Match and Decode (MAD) algorithm, and provide its analytical noiseless recovery guarantees. We propose a parallel greedy search technique called parallel MAD (PMAD) to improve performance. We describe the applicability of GSPARC with PMAD decoder for multi-user channels, providing a non-orthogonal multiple access scheme. We present numerical results comparing the block error rate (BLER) performance of the proposed algorithms for GSPARC in AWGN channels in the short block length regime. The PMAD decoder gives better BLER than the approximate message-passing decoder for SPARC. GSPARC with PMAD gives comparable and competitive BLER performance compared to other existing codes. In multi-user channels, GSPARC with PMAD decoder outperforms the sphere packing lower bounds of an orthogonal multiple access scheme with the same spectral efficiency.

صحيحٌ أنّ الحياة تجدد، والتّجدد سرّ الوجود، وصحيحٌ أنّ الوجود لو غاسسحب عنه التّجدد فارق الحياة، لكنّ الماضي أيضا له عبقه وحيويته ووجوده الكائن فيه، وما يحتاجه تجدد فقط ليحيا حياة ثانية، ولكيلا يَهمد ويندثر، تهدف هذه الدّراسة إلى تجدد التّراث، والتّعرف على علم الاكتناه وببلوغرافية المخطوط وأثرهما في إثراء السّاحة العلميّة والثّقافيّة، يتيح هذا المفهوم بما هو علم وفنّ فرصة الكشف عن تماثل إبداعيّ في شتّى العلوم والفنونّ، بين سالف العصور وبين الواقع الحاليّ، وأثبتت الدّراسة أنّ التّراث العربيّ الإسلاميّ عبارة عن بِساطٍ زاهٍ ثريّ، نسجته أيد وأفكار مبدعة معطاء، أفرغت طاقتها وثقافتها وأدبها فيه، وكلّ تلك القرائح المُبدعة تستحق منّا الإعزاز والإكرام، فكأين من تجربة وعلم وإبداع هما طيّ للنّسيان لولا المعول على تراث الأجداد، إذ من خلاله يمكن فهم العلائق بين ما كان وما يكون، وللعرب المشرقيين يُعزى فضل إنجاب المبدعين في شتّى المجالات، ولهم قصب السّبق للإنتاج الإبداعيّ، فهمّ أمّة ولود متنوّرة خلّفت أعظم الهامات، وأسست أهمّ العلوم كذلك الفنون، وهذا ما يُثير فينا الإعجاب والتّقصي لدراسته، والنّاظر لمسار اللّغة العربيّة وأثَر مواقع وقنوات التّواصل الثّقافيّ و(التكنلوجيا) الحديثة يرى بجلاء الخطر الماحق، والمصير المُرعب الّذي قد تنحدر إليه ثقافتنا، الّذي يجعل مصيبتنا في تراثنا ولغتنا تتصاغر دونها كلّ مصيبة، ولابدّ إذا من تضافر جهود الغيارى على التّراث الثّقافيّ والدّينيّ واللّغويّ، فيعمدون لإحياء الكتب الصّفراء الغنيّة المغمورة، والاهتمام بها، ففيها علم وفنّ زاخران، هذا وقد اعتمدنا المنهج الوصفيّ وهو ما يناسبنا في بيان أهميّة التّحقيق في رفد الثّقافة، وأبنّا مدى تأثير عمل المحقِّق سِلبا وإيجابا في إثراء التّراث.

The Supreme Prophet (pbuh) is for all human beings, and for all times. According to the Holy Qur'an, this universalism of the Prospphet (pbuh) is not of much interest to most people. Some of the Prophet's addressees are followers of the heavenly religions. One of the mission of the Prophet (pbuh) is to engage peacefully and to use constructive dialogue with the followers of the heavenly religions. One should know how to treat the followers of the heavenly religions according to the teachings of the Holy Quran. Is it the principle of strife, conflict, and elimination, unless they believe; Or according to the Holy Quran, Muslims can coexist peacefully with followers of the heavenly religions. For the Holy Qur'an, the language of discourse between the heavenly religions is peaceful coexistence, constructive dialogue and cooperation based on common principles. In this study, the authenticity of peace and the constructive dialogue and peaceful coexistence of Islam with the followers of the heavenly religions are investigated in line with the universality of the Quranic teachings. The Holy Qur'an has considered peace and coexistence with other religions and nations as a fundamental principle in its constitutional system. Verses of the Holy Quran deny racism, coercion, false prejudice, and welcome peace, cooperation based on common principles, and peaceful dialogue, And while recognizing past prophets and scriptures, it respects the rights of minorities. Some of the Qur'an's strategies for securing peaceful coexistence with non-Muslims are as follows: Rejecting racism; Fighting the illusions of the superiority of the youth of other religions; Freedom of thought; A confession to the rights of minorities; Co-operation in International Affairs; Welcoming peace offer; Emphasis on international peace; Call for peaceful coexistence and common principles And a peaceful dialogue

Published: March 2023

The phylogeny of the species of Epilobium in Kurdistan Region-Iraq was investigated by using six in-group species: E. anatolicum Hausskn. subsp. anatolicum, E. hirsutum L., E. obscurum Schreber, E. parviflorum Schreber, E. rechingeri Raven., E. tetragonum L. and one out-group related genus: Ludwingia grandiflora (Michx.) Greuter & Burdet, based on trnL-F intergenic region of chloroplast DNA and internal transcribed spacer (ITS) of nuclear ribosomal DNA. In addition, the pollen morphology of seven species of Epilobium (the previous mentioned species with E. ponticum Hausskn.), was examined by using Light Microscope (LM) and Scanning Electron Microscope (SEM). Individual analysis of trnL and ITS sequence data indicated monophyly of the genus Epilobium, the results of bayesian and maximum parsimony displayed two clades of Epilobium with high supports (bs=100%, pp=1.00). The pollen grains usually tetrads, radially symmetrical, isopolar, numerous, yellow, five species appeared oblate whereas E. rechingeri and E. tetragonum were suboblate; the polar view was triangular and the equatorial view was ellipsoid; their sizes were medium (medium-large in E. hirsutum and E. parviflorum). The apertures were triporate. The exine sculpturing were not obvious.

Introduction: Coronary artery bypass grafting effectively relieves signs and symptoms of myocardial ischemia. Coronary artery bypass grafting (CABG) surgery aims to restore adequate blood supply to the ischemic heart and the success of the operation depends mainly upon the patency of the grafts. A major contributing factor to the early atherosclerotic process is damage to the vessel wall, specially endothelial injury that occurs during the conventional harvesting of the vein, using high-pressure distension. Objective: To determine the comparison of peroperative venous grafts number and distribution of distal venous grafts. Materials and Methods: This comparative cross-sectional study was carried out at the department of cardiac surgery in National Heart Foundation Hospital & Research Institute. The period of study was from January, 2019 to September, 2020 and purposive sampling method was applied for this study. The study population was 80, with two groups having 40 patients each. Grouping of patients were done by purposive sampling method and all patients underwent elective coronary artery bypass graft in 2015. These groups of patients again investigated through coronary computed tomography angiogram in 2020 for evaluation of saphenous vein patency and occlusion rate. Data was collected by using a standardized semi-structured questionnaire, face to face interview and hospital records. Results: Among the study population mean age in group A was 59.38±7.43 years and in group B was 58.70±8.27 years. The difference in age between two groups was not statistically significant (p=0.702). There was no statistical significance of gender in between the two study groups (p=0.762). The comparison of the presence of Chest pain (p=0.799), Dyspnea (p=0.262), Palpitation (p=0.633) in group A and B patients were statistically not significant (p>0.05). The number of venous grafts of group A was 3.65±0.74 & group B was 3.58±0.55 where the finding was statistically ............

Introduction: Anorectal Malformation (ARM) is one of the common congenital anomalies in the world. Incidence worldwide is 1 in 3000 to 5000 live births. Anorectal malformation is a well-recognized condition since antiquity and represents a wide spectrum of defects. Anorecto-Vestibular fistula (ARVF) is the commonest ARM in female children. Recto‑Vestibular anus is the most common Anorectal Malformation (ARM) in female patients, in which rectum opens immediately behind the hymen in the vestibule. Aim of the Study: The aim of this study was to evaluate and compare the outcome between Trans- Fistula Anorectoplasty (TFARP) and Anterior Sagittal Anorectoplasty (ASARP) in the management of Recto-Vestibular Fistula (RVF) among neonates in a tertiary care hospital .Methods: This was a prospective comparative study and was conducted in the Faculty of Pediatric Surgery of Bangladesh Shishu Hospital & Institute, Dhaka, Bangladesh during the period from February 2017 to January 2021. In our study we took sixty (60) female neonates with vestibular fistula (VF). Among all neonates TFARP was done in 30 neonates and ASARP was done in 30 neonates for definitive correction of RVF. Result: In total 60 patients from both the groups completed the study. In our study we found the mean operation time in TFARP group and ASARP group was 65.97±4.63 minutes and 69.37±4.76 minutes. After operation, 60% neonates in TFARP group and 90% neonates in ASARP group developed complications. Most occurred complication was skin excoriation (20% & 26.67%) in TFARP & ASARP groups respectively. Wound dehiscence was noted significantly more in ASARP group. In TFARP group, 63.3% neonates had good, 33.3% neonates had fair and 3.3% neonates had poor functional score while in ASARP group, 56.7% neonates had good functional score & 43.3% neonates had fair functional score. Conclusion: In conclusion, we found that TFARP may provide the best postoperative cosmetic appearance, parent’s satisfaction, ..........

Introduction: The aim of this study was to evaluate the anesthesiological management of emergency caesareans at the CHU Gabriel TOURE. Methodology: This was a prospective study that took place at the CHU Gabriel TOURE in the Anesthesia Resuscitation department and in the operating theater of the Gyneco-Obstetrics department from August 01 to October 31, 2021. It concerned all caesarean sections performed in the Gyneco-Obstetrics department of the CHU Gabriel TOURE during a period of three months. All patients who came urgently to the Gyneco-Obstetrics department during the study period with an indication for emergency caesarean section Patients operated for emergency caesarean in another center were not included: caesareans performed outside our study period, planned caesareans, ruptured GEU (ectopic pregnancy), haemostasis hysterectomy. The information obtained from the patients and in the prenatal consultation book is compiled on an individual data collection sheet on which the variables to be studied appear. Statistical analysis was performed using SPSS version 25 software. Microsoft Word software was used for word processing. Results: During the study period, we performed 168 emergency cesarean sections out of 389 cases of cesarean section, i.e. a frequency of 43.18%. Conclusion: The practice of emergency obstetric anesthesia poses organizational difficulties, linked to the absence of a post-operative monitoring room, information from the anesthesia team and availability of products. PRH was the most frequent surgical indication; for this reason, GA has been the most practiced technique. Many patients were transferred to intensive care, i.e. 38.69% of cases and we recorded 38.69% of complications.
