Doug Kahn: Class Master
Authors: Ross Dennis
Published: March 2022

Doug has always been a bit of a departure from the professorial norm. Teaching for Doug was no accommodation to the job, no activity collateral to his true ambition, but rather an openly genuine attempt to engage his students and pull them into a subject that he obviously loved. His evident joy when in front of a class closed any distance with his students, no small feat considering the subject matter. Tax is forbidding territory for many, and Doug was justifiably known for his refusal to dumb the material down. Thus, much of his class may have been there reluctantly, taking the course only because they’d been told “you have to have it.” I won’t claim that Doug reached all or even most of those, but it wasn’t for lack of effort—a fact that I believe all of his students appreciated, even those for whom the subject matter was a bridge too far.
A Grateful Testimonial to Doug Kahn
Authors: Perris Terrence
Published: March 2022

It is difficult for me to accept the reality that Doug Kahn is about to retire after a triumphant fifty-two year tenure as a professor at the University of Michigan Law School. For much of the nearly forty-seven years of my association with the Law School, first as a student and then as an alumnus, Doug has practically symbolized the Law School for me, as he went from being a revered teacher, to a valued mentor, to a dear friend, to a colleague and co-author, and, dare I say, to virtually a member of the family. But I am only one of many Michigan students whose lives and careers were touched and positively influenced by this extraordinary scholar, superb teacher, wise mentor, and very kind-hearted man. I am and always will be grateful beyond measure that our paths crossed, and am especially grateful that it happened early enough in Doug’s teaching career to give us the opportunity to also become colleagues, co-authors, and good friends in the years since I graduated.

Tinjauan Hukum Platform Digital Sapardi_ID Berdasarkan Undang-Undang Nomor 8 Tahun 2016 Tentang Disabilitas
Authors: Zulfiani Yayang Nuraini
Published: March 2022

Negara Republik Indonesia merupakan negara yang berdasarkan Pancasila dan UndangUndang Dasar Negara Republik Indonesia Tahun 1945, artinya masyarakat Indonesia harus senantiasa menghormati dan menjunjung tinggi harkat dan martabat manusia. Dengan disahkannya Undang-Undang Nomor 19 Tahun 2011 tentang Pengesahan Convention on the Rights of Persons with Disabilities (Konvensi Hak-hak Penyandang Disabilitas) tentunya menunjukkan komitmen Pemerintah Indonesia serta seluruh masyarakatnya untuk menghormati, melindungi, dan memenuhi hak Penyandang Disabilitas yang pada akhirnya diharapkan dapat meningkatkan kesejahteraan Penyandang Disabilitas melalui partisipasi aktif masyarakat dalam menjamin pemenuhan hak penyandang disabilitas dalam segala aspek kehidupan. Pada era revolusi 4.0 tentunya penting untuk senantiasa berkomunikasi dan berbagi informasi terhadap penyandang disabilitas. Karena jangkauan hukum dan pemerintah dalam rangka mensejahterakan penyandang disabilitas sangatlah terbatas, perlu adanya partisipasi aktif masyarakat untuk ikut memahami dan membantu kebutuhan khusus penyandang disabilitas, dalam rangka pelaksanaan dan pemenuhan hak penyandang disabilitas yang lebih berkualitas, adil dan sejahtera. Platform Digital Sapardi_ID menjadi media edukatif bagi masyarakat umum untuk memahami penyandang disabilitas sehingga masyarakat dapat belajar berkomunikasi dan menghargai Penyandang Disabilitas sebagaimana Undang-Undang Nomor 8 Tahun 2016 tentang Penyandang Disabilitas. Penelitian ini menggunakan metode penelitian kualitatif secara deskriptif dengan sumber kepustakaan, survey lembaga dan survey mandiri, dengan hasil bahwa dalam implementasinya platform ini masih kurang menjangkau banyak pihak untuk berpartisipasi aktif serta masih perlu pengembangan program dan kerjasama dengan berbagai pihak.

Peculiarities of traits expression of feed and seed productivity of alfalia collection accessions under high soil acidity
Authors: Buhaiov VD , Horenskyi VM
Published: March 2022

Aim. To study and assess the environmental adaptability of feed and seed productivity of alfalfa collection accessions under high soil acidity by determining its components - regression coefficient and stability variance.
Results and Discussion. Breeding nurseries were established by summer coverless sowing: gutter sowing (row spacing 15cm) - for feed productivity; wide-row sowing (45cm) – for seed productivity. The record plot area was 3 m2, in two replications. To assess the feed productivity, we measured the dry matter yield of four mowings (budding phase); to assess the seed productivity, we determined yield from the first mowing. The environmental plasticity coefficient for the feed productivity (bi) varied across the studied accessions from ̶ 1.24 to 2.33. bi> 1 was found in 16 accessions, but the dry matter yields from most of them were significantly lower than that from the check variety, Syniukha. Low values (0 – 0.34) of the stability variance (Si2) indicate that the obtained empirical values differ little from the theoretical ones. As to the seed productivity, bi> 1 was detected in 16 accessions, 8 of which exceeded the check variety, Syniukha, in terms of seed yield. The stability variance varied in a fairly wide range from 0.12 to 308.93. The obtained values of Si2 confirm the difficulty of alfalfa breeding for increased seed productivity compared to feed productivity, which are often positively affected by opposite hydrothermal conditions: drought positively affects the seed yield, while excessive rainfall boost the feed productivity.
Conclusions. Alfalfa accessions with a relatively strong response to the improvement of growing conditions with increased feed and seed productivities were selected; they can be used as starting material in breeding for these traits: Radoslava, Olha, Vavilovka (Rodnychok) (Ukraine); Evrika 1 (RF); Ferax 58 (Canada).

Authors: Zadorozhna OA , Yehorov DK
Published: March 2022

Aim. Impact determination of rye seeds storage with 5-7% moisture content at unregulated temperature under eastern forest-steppe of Ukraine conditions on germination, productivity elements and plant height.]
Results and Discussion. Results analysis caried on of rye seed storage of simple hybrid and two breeding lines of Institute of Plant Industry named after V. Ya. Yuriev of NAAS. These accessions stored in the depository at unregulated temperature under conditions of eastern forest-steppe of Ukraine with seed moisture content at 5-7% for 42 months. Average temperature in the depository where these studies were carried out was 9°C. There was no advantages were found for rye seeds longevity with different moisture levels within 5-7%. Analysis of yield components and plant height did not reveal a significant negative impact of the storage regimes used on these traits during the specified period. Significant correlation was found for individual accessions between field germination of seed and the level of precipitation in the month of sowing year; between plant height, productivity and precipitation during the development critical phases of season growing.
Conclusion. Possibility of maintaining the initial germination of rye seeds for 42 months without significant changes was established. Seed with moisture content 5-7% of certain genotypes should storage at unregulated temperature under conditions of eastern forest-steppe of Ukraine in sealed container. Consequence of such storage conditions for rye seeds is the absence of significant variation of productivity elements.
It’s a ‘two-way street’: resident perspectives of effective coaching relationships in the clinical learning environment
Authors: Trier Jessica , Turnnidge Jennifer , McGuire Cailie S , Côté Jean , Dagnone J Damon
Published: March 2022

Background: Coaching has gained traction in postgraduate medical education to enhance interactions between residents and clinical teachers, but these relationships present unique challenges and tensions. In order to realize the promises of coaching in medical education, we must understand how coaching relationships can be enacted to optimize resident development. The purpose of this study was to explore residents’ perceptions of key characteristics for effective clinical teacher-resident (CT-R) coaching relationships. 
Methods: We conducted four focus groups and eight interviews with residents at a Canadian academic center. Using a social constructionist approach, focus groups and interviews were audio recorded, transcribed verbatim, and thematically analyzed. 
Results: Residents described three main characteristics that contributed to effective CT-R coaching relationships: safe, meaningful, and collaborative. Residents emphasized that these characteristics needed to be bidirectional in nature to be most effective, in that both the resident and clinical teacher embodied these characteristics. 
Conclusions: Residents identified that effective coaching relationships were shaped not only by clinical teacher behaviours, but importantly, the quality of the interpersonal relationship that was fostered. Thus, it is imperative to consider the bidirectional nature of the CT-R coaching relationship when striving to enhance resident development.
Observational Study: Sublingual Immunotherapy Compliance In The Paediatric Population
Authors: Wurttele Juan Trujillo
Published: March 2022

Background: Sublingual Immunotherapy (SLIT) is becoming an increasingly popular choice of treatment for allergic rhinitis. Cork University Hospital (CUH) is the regional paediatric allergy centre in the Munster Region (Ireland). This study looked in detail at the paediatric Population commenced on SLIT within 2011 to 2020 inclusive, assessing demographic characteristics and compliance in this cohort.

Methods: A retrospective chart review was conducted focusing on the population who were commenced on SLIT in the paediatric allergy and pulmonology services in CUH. This study was carried out in conjunction with INFANT Research Centre.

Results: A sample of 72 patients were commenced on Immunotherapy in CUH between the defined timeframe, with information gathered on a total sample of 67 patients. Compliance rate within the total sample who underwent SLIT was 79.1% (53 patients completed), with 20.8% (14 patients) failing to complete the treatment. Children over 10-years old had a statistically significant higher proportion of completion in contrast to those under 10-year (P-value=0.041).

Conclusion: CUH population have a good compliance with SLIT comparable with other cohorts. Decreased compliance is associated with the number of SLIT treatments, age of patient, co-morbid asthma, and antihistamine use.
Modified Radial Technique
Authors: Clavijo Paulina Cisneros
Published: March 2022

In 1948, Radner described the first radial approach for the cardiovascular study. Subsequently, in 1989, L. Campeau described the radial technique to perform a coronary angiography, and in 1993 F. Kiemeneij used it for a percutaneous coronary angioplasty procedure, emerging the trans radial access as an attractive alternative to the femoral access. New advances in interventionism have made the radial approach an easily accessible technique, without major complications and with greater comfort for the patient. It certainly requires a greater learning curve than the femoral one; however, its advantages over femoral access have been demonstrated. Of the complications the most frequent is the spasm that leads to failure in 38% of the procedures and produces dissections, ruptures, avulsion, etc; despite the use of spasmolytic agents or prior anatomic evaluation. Therefore, we have shown that the technique can be modified simply with the placement of a 25cm hydrophilic introducer that avoids crossing through the forearm segment. With which all kinds of complications are avoided, generating greater comfort in the patient and technically favoring the procedures.

Physical Resource Management and Maintenance Culture in Nigerian Universities
Authors: Ofor-Douglas Stella
Published: March 2022

This paper deals with physical resource management and maintenance culture in Nigerian universities. Physical resource is the resource that can be seen (tangible). Resource management is the proper utilization and management of resources such that they are adequate and efficient for the needs of individuals in an organization. The importance of resource management in universities is to see whether the human resource is over or under-allocated in a particular faculty in the university to avoid wastage. Maintenance culture refers to the measures taken so that materials and resources are maintained properly. Universities refer to institutions of higher learning whereby an individual seeks to further his education after the secondary school level. The absence/ poor maintenance of physical resources in Nigerian universities would undoubtedly lead to a decline in the productivity of the university. This paper is to provide a means of efficient management and maintenance of physical resource in Nigerian universities. The objective of this paper is to proffer solutions to the challenges of effective management and maintenance of physical resources in Nigerian universities. The challenges facing the effective management and maintenance of physical resources in Nigerian universities were provided in this paper to include inadequate funding, inadequate facilities, and misuse of university facilities, amongst others. A conclusion was made and a way forward for the challenges facing the efficient management and maintenance of physical resource in Nigerian universities were provided. This includes the provision of adequate funds, punishment of greedy administrators that covert funds, provision of adequate modern facilities, proper maintenance of physical resource from time to time, amongst others.

Authors: Lara Romero C , Olvera Muñoz R , Cadena Herrera ML , Belvis Jimenez M , Otero Lopez-Cubero S
Published: March 2022

Introducción: La colecistectomía laparoscópica es el tratamiento gold standard en la colecistitis aquda litiásica, si bien su manejo cuando existe coledocolitiasis concomitante es controvertido.

Objetivos: Evaluar los reingresos por complicaciones biliares en pacientes con colecistitis aguda tratados de forma conservadora por sospecha de coledocolitiasis concomitante.

Material y métodos: Estudio retrospectivo bicéntrico. Recogida de datos: Junio 2015 – Octubre 2017. Diagnóstico de colecistitis aguda según criterios de Guía de Tokyo y alto riesgo de coledocolitiasis según American Asociation for Gastroenterology.

Resultados: Se incluyeron 137 pacientes de los cuales la colecistectomía se pospuso en 86 (62,8%) por sospecha de coledocolitiasis concomitante. Dicha obstrucción de la vía biliar se confirmó en el 42,3% de los casos. Cuando la vía biliar no está dilatada en la ecografía el valor de bilirrubina como predictor de coledocolitiasis fue 4,5mg/dL. La tasa de reingresos en paciente no intervenidos fue del 23,3%.

Conclusiones: el tratamiento conservador de la colecistitis aguda por sospecha de una coledocolitiasis concomitante hace que se demore la colecistectomía. Dicha demora supone un aumento de los reingresos hospitalarios por complicaciones biliares.

Es fundamental realizar un diagnóstico precoz e intervención quirúrgica inmediata para prevenir la isquemia y necrosis intestinal. La mortalidad asciende al 42-67% y está directamente relacionada con el tiempo transcurrido desde el inicio de los síntomas hasta la intervención.
Parallel Flow of a Pressure-Dependent Viscosity Fluid through Composite Porous Layers
Authors: Zaytoon M. S. Abu , Hamdan M. H.
Published: March 2022

Flow of a fluid with pressure-dependent viscosity through a composite of two porous layers is considered in this work in an attempt to validate velocity and shear stress continuity conditions at the interface, and are popular in the study of flow over porous layers and through composite layers when viscosity of the fluid is constant. For the current problem, conditions at the interface between the porous layers reflect continuity assumptions of velocity and shear stress, with additional continuity assumptions on pressure and viscosity. Viscosity is assumed to vary continuously and exponentially across the layers as a function of pressure. Analytical solutions are obtained to illustrate the effects of flow and media parameters (Darcy numbers, layer thicknesses, angle of inclination, and viscosity adjustment parameter) on the dynamic behaviour of pressure-dependent viscosity fluids in porous structures. All computations, simulations and graphs in this work have been carried out and obtained using Maple 2020 software package.

Review of modern military insensitive high explosives
Authors: Krnjic Kerim
Published: March 2022

In the last twenty years, high energetic materials have changed significantly. Several factors have influenced the development of these materials, which include new operational requirements such as insensitive ammunition (IM), as well as factors in the availability of new materials and new production techniques, safety assessment, and modeling. All this enables more efficient use of materials and a more detailed understanding of the processes involved in the application of new technologies. This work presents new insensitive secondary high explosives such as TATB, FOX-7, GUDN, NTO, and others that are in different stages of development. A review of these explosives is given and their stability, reliability, and specific application are described. Energy materials are known to be chemical compounds or mixtures that contain significant amounts of energy and it has been shown that successful design of new energetic materials with customized performance properties and increased stability is possible. The properties of new insensitive energetic materials must be further researched and improved before they can be used in new or existing systems. Insensitive ammunition testing is a vital component of many national IM programs. The international community has established requirements for testing the insensitivity of materials and developed six unique tests based on testing the response of the material to the effects of heat, impact, or shock.
Numerical simulations of the formation behavior of explosively formed projectiles
Authors: Salkičević Minel
Published: March 2022

Explosively formed projectile (EFP) is a self-forging shape charged structure having very high penetration ability compared to conventional kinetic energy projectile. The penetration capability of an EFP is strongly dependent on various design parameters. The main parameters can be roughly divided into geometric and material parameters used in the warhead configuration.

The present research is an effort to study the effect of metal casing thickness, type of metal used for casing, explosive type, liner thickness, type and configuration on the formation of EFP. Effectivness of an EFP is studied in terms of final velocity and shape of formed penetrator. The study is carried out by performing a number of simulations by using explicit finite element (FE) hydrocode ANSYS/Autodyn.
John Rawls y el problema de la desigualdad dentro y más allá de las fronteras
Authors: Turégano Isabel
Published: March 2022

En la teoría de la justicia de John Rawls, la preocupación por la igualdad es central como imperativo de justificación recíproca de la estructura institucional básica. Esta propuesta sigue siendo adecuada para enfrentar el problema de la desigualdad en nuestros días. Su obra central, que ahora cumple 50 años, sigue proporcionándonos instrumentos para comprender las asimetrías de riqueza como asimetrías de poder. Algunas de las debilidades, no obstante, provienen de su concepción ambigua de esa estructura básica y de la idealización de su modelo de justicia, las que pueden distorsionar el modo de abordar la pluralidad de formas de desventaja que asolan los contextos no ideales. En todo caso, el compromiso igualitario de Rawls se vio esencialmente comprometido en su propuesta de un Derecho de Gentes que, comparado con la versión de la justicia que defendió para el marco estatal, es muy modesta. La supuesta coherencia de los fundamentos relacionales de su teoría de la justicia estatal e internacional no puede ser obstáculo para una teoría más exigente de la justicia global pensada desde algunas de las ideas centrales que Rawls nos legó.
MODELING THE APPLICATION OF AUGMENTED REALITY TECHNOLOGY IN THE EDUCATION PROCESS
Authors: Stundžiaitė Indrė , Davidavičienė Vida
Published: March 2022

Augmented reality technology (AR) is strengthening its position in our daily lives every year. The main goal of augmented reality technology is to digitize the world around us by adding additional information that is relevant and attractive to the consumer in a particular sector. Gadget stores are adding more and more fun and useful PR programs, while big companies and startups are coming up with new ideas on how to effectively apply augmented reality technology to business processes. Education is one of the areas where the application of PR technology is receiving increasing attention and funding. It is also anticipated that the penetration of this technology into education will only increase and the PR education industry will expand. The aim of this article is to analyze the impact of PR technology on the participants of the educational process and to form an application model in Lithuanian general education schools. The article examines the possibilities of applying augmented reality technology in the education sector, distinguishing the level of basic schools. The impact on the educational process and its participants is also analyzed and evaluated. Several research methods are used and combined in the work – the analysis of scientific literature is combined with classroom research to find out the already applied PR models at different levels of the education sector and the questionnaire survey method to assess the situation of PR technology use in Lithuanian basic schools. The results revealed that augmented reality technology is still poorly applied in Lithuania in the educational process, mostly due to human and financial resources. The analysis presented in the article can be useful for educational institutions wishing to implement smart technologies, which are also designed for an innovative teaching process.

We present a near-infrared transmission spectrum of the long-period (P = 542 days), temperate (T
eq = 294 K) giant planet HIP 41378 f obtained with the Wide-Field Camera 3 instrument aboard the Hubble Space Telescope (HST). With a measured mass of 12 ± 3 M
⊕ and a radius of 9.2 ± 0.1 R
⊕, HIP 41378 f has an extremely low bulk density (0.09 ± 0.02 g cm−3). We measure the transit depth with a median precision of 84 ppm in 30 spectrophotometric channels with uniformly sized widths of 0.018 μm. Within this level of precision, the spectrum shows no evidence of absorption from gaseous molecular features between 1.1 and 1.7 μm. Comparing the observed transmission spectrum to a suite of 1D radiative-convective-thermochemical-equilibrium forward models, we rule out clear, low-metallicity atmospheres and find that the data prefer high-metallicity atmospheres or models with an additional opacity source, such as high-altitude hazes and/or circumplanetary rings. We explore the ringed scenario for HIP 41378 f further by jointly fitting the K2 and HST light curves to constrain the properties of putative rings. We also assess the possibility of distinguishing between hazy, ringed, and high-metallicity scenarios at longer wavelengths with the James Webb Space Telescope. HIP 41378 f provides a rare opportunity to probe the atmospheric composition of a cool giant planet spanning the gap in temperature, orbital separation, and stellar irradiation between the solar system giants, directly imaged planets, and the highly irradiated hot Jupiters traditionally studied via transit spectroscopy.

Introduction:Plumbago zeylanica grows widely in many tropical countries. In Indonesia, this plant, known as Daun Encok, has some beneficial effects on human health. 

Aim: This exploration study aimed to identify the plumbagin compound in P. zeylanica roots from Indonesia. 

Materials and methods: Dried roots of P. zeylanica were manually ground and then the powder was macerated using ethanol and chloroform for 24 hours at room temperature. All extracts of P. zeylanica were then analyzed using gas chromatography-mass spectrometry (GC-MS). Plumbagin concentration was measured by comparing the extract with pure plumbagin.

Results: GC-MS analysis of ethanol extract and chloroform extract of P. zeylanica roots showed the presence of plumbagin as the highest peak. Plumbagin concentration in ethanol extract was 13%, while in chloroform extract it was 81%.

Conclusions: The chloroform extract of P. zeylanica root from Indonesia demonstrates a higher concentration of plumbagin compared to ethanol extract. 
Cone beam computed tomographic characterization of short root anomaly in chloroquine-induced Stevens-Johnson Syndrome – a case report
Authors: Yadav Vijay , Sharma Sidhartha , Kumar Vijay , Chawla Amrita , Logani Ajay
Published: March 2022

Stevens-Johnson syndrome (SJS) is a rare medical condition with severe mucocutaneous reaction due to infection or adverse drug reaction. The present case reports the impact of chloroquine-induced SJS on the tooth root development. A 20-year-old Indian male reported to conservative dentistry and endodontics speciality clinic with the chief complaint of food lodgement and sensitivity in maxillary and mandibular posterior teeth. He had a past medical history of severe cutaneous reaction after taking Tab. Lariago (chloroquine) for treatment of malarial fever at the age of 8 years. The acute inflammatory immune response was managed by hospitalization and administration of steroids and anti-inflammatory drugs. Clinical examination revealed dry mucosa, carious teeth with adequate oral hygiene. Panoramic X-ray showed multiple teeth with short roots. A detailed cone beam computed tomographic scan (CBCT) demonstrated a healthy bone trabecular pattern with the absence of any periapical radiolucency. Short, blunt roots with immature apex were seen in many teeth. Based upon the measurement of root to the crown ratio on the CBCT scan and correlating the development status of teeth with the medical history, a diagnosis of short root anomaly (SRA) after chloroquine-induced SJS was made. This is the first report to describe the three-dimensional features of teeth with SRA in a patient with SJS. Diagnostic, restorative, and endodontic implications of SJS are highlighted.

The aim of presenting this case was to show the difficulties in making the differential diagnosis of viral meningitis during the COVID pandemic situation.

We report a case of a young man with clinical features of viral meningitis and with epidemiological history of COVID-19 in his family. The patient complained of fever, headache, photophobia, nausea, myalgia, and fatigue. He gave a history of diarrhea and vomiting two weeks before admission and close relatives with COVID-19. The neurological examination revealed a meningeal irritation syndrome. The diagnostic tests we performed were as follows: nasopharyngeal swab and PCR of cerebrospinal fluid (CSF) for SARS CoV-2, computed tomography scan of the head, general CSF examination, viral tests, and microbiology of CSF, enzyme-linked immunosorbent assay (ELISA) IgM and IgG.

The results were consistent with viral meningitis due to HSV-1 in simultaneously found high titres of plasma SARS CoV-2 specific IgA and SARS CoV-2 specific IgG and active viral serum infection for CMV and EBV.

We present a case of a 47-year-old woman with type 1 multiple endocrine neoplasia, primary hyperparathyroidism, insulinoma, and nonfunctioning pituitary adenoma. In July 2017, the patient was referred to the Department of Nuclear Medicine of St George University Hospital in Plovdiv for a PET/CT scan because of persistent hypoglycemic episodes and high serum insulin levels. A whole-body PET/CT examination was performed 65 min after intravenous application of 188 MBq 18F-FDG on a hybrid PET/CT scanner (Biograph mCT 64, Siemens). We detected a low metabolically active lesion 10 mm in diameter (SUVmax - 2.00), located below the left thyroid lobe suspicious for parathyroid adenoma. In the remaining scanned areas there were no PET/CT data for other areas with increased glucose metabolism with malignant characteristics that could be associated with the underlying disease. 

For further characterisation of the lesion, two months later we performed a single-isotope dual-phase 99mTc-tetrofosmin scintigraphy combined with an early SPECT technique on a SPECT gamma camera (SYMBIA E DUAL). The examination visualized a zone of hyperfixation located dorsally to the caudal portion of the left thyroid lobe associated with a hyperfunctioning parathyroid adenoma.

This case allowed us to compare two nuclear medicine modalities with different equipment and radiopharmaceuticals – PET/CT with 18F-FDG and single-isotope dual-phase 99mTc-tetrofosmin scintigraphy combined with an early SPECT in one and the same patient. Different factors can explain the acquired different diagnostic information.

Endoscopic self-expandable metallic stent (SEMS) decompression in patients with bowel obstruction due to colon carcinoma has been practiced for over two decades now, both in potentially curable cases and metastatic cancer. Using this case series, we aim to review the literature on the subject and to present our initial experience with using this technique as a bridge to single stage surgery, thus minimizing colostomy creation.We retrospectively reviewed seven cases of bowel obstruction due to left-sided colonic cancer, between March 2020 and March 2021. All patients received SEMS prior to being treated, 7 to 13 days later, using either laparoscopic surgical techniques or open surgery methods. All seven patients underwent single stage surgery, eliminating the need for placing a temporary or permanent stoma, therefore minimizing the hospital stay and increasing the quality of life of the individual.We concluded that treatment with SEMSs for bowel obstruction in colorectal cancer was safe and well tolerated, resulting in primary anastomosis and restoration of the intestinal passage and low short-term morbidity.
Naftali Bennett et le sionisme religieux
Authors: Cohen Samy
Published: March 2022

Le gouvernement israélien est dirigé par un sioniste religieux. Il importe de connaître l’histoire de ce courant adepte du « Grand Israël », qui connut les pires dérives. Comment un groupe naguère marginal a-t-il réussi à apparaître comme héritier des fondateurs d’un État laïc ? Son ascension paraît durable, les sionistes religieux occupant des postes clés. La coalition gouvernementale que préside Naftali Bennett est très fragile, mais aucun de ses membres n’a intérêt à la déstabiliser pour l’instant.
On the Adoption of the EU’s New Rule of Law Conditionality Mechanism
Authors: Bos Ellen , Kurze Kristina
Published: March 2022

Le recul démocratique et les instruments à même de protéger l’État de droit sont des thèmes débattus dans les instances de l’UE depuis plusieurs années. Cependant, le Conseil européen de décembre 2020 fut le premier à dégager un accord sur l’introduction d’un mécanisme général de conditionnalité au respect de l’État de droit. Désormais, l’allocation de fonds européens aux États membres est conditionnée à l’adhésion aux principes de l’État de droit. Afin d’expliquer comment cette décision d’une grande portée a pu être prise malgré la persistance d’intérêts profondément divergents, notre analyse s’appuie sur la théorie des courants multiples. Sur cette base, nous soutenons que la crise du COVID-19 a créé une fenêtre d’opportunité qui a été utilisée avec succès pour remettre à l’ordre du jour une proposition préexistante de mécanisme de conditionnalité de l’État de droit et — plus important encore — pour adopter un règlement correspondant. L’article se termine par une brève perspective concernant la mise en œuvre du mécanisme de conditionnalité de l’État de droit.
Espace de fiction – Espace de reconnaissance. Théâtre, don et vérité
Authors: Hénaff Marcel
Published: March 2022

Invitant à dépasser la distinction traditionnelle entre mimesis et diegesis , cet article se propose d’envisager en quoi le théâtre, comme activité de représentation fictionnelle de séquences d’actions, peut être compris de manière pertinente selon la catégorie du don. Qu’est-ce qui se joue et se donne dans le jeu théâtral ? Ce jeu, à l’instar des rituels d’échange des sociétés traditionnelles, est un jeu sérieux. Il implique dans son agencement et par l’effet de la performance, un pacte de reconnaissance entre acteurs et spectateurs. Il relève d’un processus de relations à la fois empathique et distancié. Et c’est dans la mesure où chacun, dans cette distance ludique, joue le jeu que peuvent circuler les affects entre la scène et la salle et que la fiction peut exercer sa prise sur la vie.
Don, transmission et attachement dans les contes
Authors: Flahault François
Published: March 2022

Joie et humour caractérisent le conte auquel est consacré la première partie de l’article. Ce conte illustre le genre de don qui nourrit la convivialité dans la vie quotidienne. Un don qui ne coûte rien au donateur mais qui témoigne de sa bonne volonté et de son ouverture aux rencontres. La seconde partie traite d’une autre sorte de don, le don intergénérationnel par lequel la force de vie est transmise à l’enfant grâce à une relation d’attachement et d’amour. Nombre de contes tournent autour de ce thème et en soulignent l’enjeu de vie ou de mort. La troisième partie concerne des contes qui mettent en scène le lien entre deux personnages de même génération. Ces contes soulignent, souvent de manière christique, le coût du sacrifice consenti par l’un des personnages pour sauver l’autre. Ces contes insistent sur la détresse, la solitude et la douleur de personnages qui en appellent à l’aimé(e). En somme, dans les contes comme dans la vie réelle, les dons apparaissent aussi bien comme le moyen de nouer une relation que comme la prix à payer pour soutenir ou restaurer un lien vital.
L’adoption dans le culte napolitain des âmes du Purgatoire
Authors: Villain-Carapella Florian
Published: March 2022

Parmi les rites associés au culte napolitain des âmes du Purgatoire, tel qu’il s’est transformé au xix e siècle, l’adoption des crânes est sans doute le plus célèbre et le plus singulier à la fois. Cette pratique qui fait sortir ces derniers de l’indifférenciation – et parfois même de l’anonymat – repose essentiellement sur l’expérience onirique de l’apparition surnaturelle des morts. En mettant l’accent sur l’élaboration narrative du rêve plutôt que sur son contenu latent, cet article se propose d’interroger la dimension socio-anthropologie de ce besoin de raconter des histoires et d’en faire don. Il apparaîtra alors que l’adoption consiste en un don de récit s’inscrivant dans une vertueuse circularité de dons où se donne à voir de façon saisissante ce que Mauss appelle le « fait social total ».
High-intensity interval training improves fat oxidation during submaximal exercise in active young men

This study aimed to examine the effects of four-weeks high-intensity interval training (HIIT) on fat oxidation responses during submaximal exercise in active young men. For this purpose, 20 active young men (who participated in the exercise three times per week) were divided into two groups, including a training group (age: 19.3±0.48 years, V̇O2peak 2.9±0.35 l/min, n=10) and a control group (age: 19.7±0.67 years, V̇O2peak 2.7±0.26 l/min, n=10). The training group performed high-intensity interval training for three sessions per week. Specifically, each session included 8-11 intensive cycling efforts comprising of 60 s duration. A 75 s low pedalling rate (30 W) was used as an active recovery between the intervals. Furthermore, a V̇O2peak test was performed prior to, at the end of two weeks and after the training period. Also, a 60 min constant cycling protocol was performed at ~60% V̇O2peak, in addition to the V̇O2peak test, before and after the training protocol. To assess plasma free fatty acids and glucose, blood samples were taken during a 60-min aerobic exercise prior to and following the training period. An increase (17.8%) in V̇O2peak was observed for the HIIT group after the training period compared to the control group (P<0.05). The HIIT group performed the 60 min sub-maximal exercise test at a lower percentage of V̇O2peak, and decreases in the respiratory exchange ratio were greater in the HIIT group than in the control group (P<0.05). Compared to the pre-test values and control group results, the HIIT group used less carbohydrate and more lipid oxidation during submaximal exercise (P<0.05). The present study’s results indicate that short-term low volume HIIT can increase aerobic capacity and fat oxidation during submaximal exercise.
