Authors: Bandekar Bhavesh , Awatagiri Kasturi , Kannan Sadhana , Rane Pallavi , Parikh Prafulla
Published: February 2021

Context:

A failure to obtain continued Institutional Ethics Committee (IEC) approval for the study before the expiry date assigned by the IEC is considered as “lapse of the IEC approval” to continue the study at the site by the Investigator. Considering this, we had conducted an audit of principal investigators (PI ') compliance for Continuing Review Application (CRA) submission timelines and decision taken on the lapses in the validity of IEC approval continuation.

Aim:

The aim of this study is to assess the pre- and post-policy trends of non-compliance management of delayed CRA submission and compare the PI's compliance for submission of CRA between Investigator Initiated trial (IIT) and Pharma studies.

Setting and Design:

The present study was a retrospective audit of CRAs of ongoing projects submitted by PIs to IEC, ACTREC.

Materials and Methods:

The data from total 199 CRAs submitted for review to the IEC between the year January 2016 and December-2017 were collected and maintained in Microsoft Excel sheet, and later, the data were exported into the SPSS software version 21 for the analysis.

Statistical Analysis:

All categorical data were presented in numbers and percentage. The first primary objective was assessed by calculating the duration between the dates of approval for any study to the date of next CRA submission. The CRAs submitted after the project expiry date were considered as a lapse in following the IEC SOP.

Results:

This retrospective audit revealed that CRA reminder sent by the IEC to the PI played an important role in compliance w. r. t timely in following the IEC SOPof the CRA by the PI. As a result, overall, 90% of CRAs showed compliance in submitting CRAs to IEC in both IIT and Pharma study. The number of lapses were reduced to 7 in the postpolicy period as compared to 15 lapses in the prepolicy period.

Conclusion:

This retrospective audit reveals that CRA reminder sent by the IEC to the PI played an important role in improving the compliance of PIs in submitting CRA to IEC. Each IEC should develop the policy to minimize the delays in CRA submission by the PI and prevent lapses in following the IEC SOP.
Equivariant vector bundles over quantum spheres
Authors: Mudrov Andrey

We quantize

SO(2n+1)

-equivariant vector bundles over an even complex sphere

\mathbb{S}^{2n}

as one-sided projective modules over its quantized coordinate ring. We realize them in two different ways: as linear maps between pseudo-parabolic modules and as induced modules of the orthogonal quantum group. Based on this alternative, we study representations of a quantum symmetric pair related to

\mathbb{S}^{2n}_q

and prove their complete reducibility.

P218 is a highly selective dihydrofolate reductase inhibitor with potent in vitro activity against pyrimethamine-resistant Plasmodium falciparum. This single-center, randomized, double-blind, placebo-controlled phase Ib study evaluated P218 safety, pharmacokinetics, and chemoprotective efficacy in a P. falciparum sporozoite (PfSPZ) volunteer infection study (VIS). Consecutive dose safety and tolerability were evaluated (cohort 1), with participants receiving two oral doses of P218 1,000 mg 48 hours apart (n = 6), or placebo (n = 2). P218 chemoprotective efficacy was assessed (cohorts 2 and 3) with direct venous inoculation of 3,200 aseptic, cryopreserved PfSPZ (NF54 strain) followed 2 hours later with two P218 doses of 1,000 mg (cohort 2, n = 9) or 100 mg (cohort 3, n = 9) administered 48 hours apart, or placebo (n = 6). Parasitemia was assessed from day 7 using quantitative PCR targeting the var gene acidic terminal sequence (varATS qPCR). By day 28, all participants in cohort 2 (P218 1,000 mg) and 8/9 in cohort 3 (P218 100 mg) were sterilely protected post-PfSPZ VIS, confirming P218 P. falciparum chemoprotective activity. With placebo, all six participants became parasitemic (geometric mean time to positive parasitemia 10.6 days [90% CI: 9.9–11.4]). P218 pharmacokinetics were similar in participants with or without induced infection. Adverse events of any cause occurred in 45.8% (11/24) of participants who received P218 and 50.0% (4/8) following placebo; all were mild/moderate in severity, transient, and self-limiting. There were no clinically relevant changes in laboratory parameters, vital signs, or electrocardiograms. P218 displayed excellent chemoprotective efficacy against P. falciparum with favorable safety and tolerability.
Prévalence et facteurs de risque de la fièvre aphteuse dans le marché à bétail de Garoua-Boulai et dans la zone de transhumance du Lom et Djerem à l’Est du Cameroun

Published: February 2021

La fièvre aphteuse (FA) est une maladie transfrontalière qui affecte les ongulés domestiques et sauvages. Elle joue un rôle très important en économie du fait de sa morbidité élevée et de sa restriction du commerce international. En vue de déterminer la prévalence de la FA bovine et les facteurs de risque de transmission de la maladie au marché à bétail de Garoua-Boulaï et dans la zone de transhumance du département du Lom et Djerem à l’Est-Cameroun, une étude rétrospective et transversale a été menée de juin à décembre 2018. Au marché à bétail, l’étude a porté sur l’observation des signes cliniques caractéristiques sur des animaux suspects. Ainsi, 58 bovins atteints de FA ont été identifiés parmi les 614 bovins suspects, soit une prévalence clinique globale de 9,44% (IC95% : 7,13% - 11,76%). Les facteurs internes tels que le sexe n’ont pas influencé la prévalence de la FA. Dans la zone de transhumance, la prévalence rapportée au niveau individuel était de 26,77%. Tous les éleveurs connaissent la FA et ont cité plus de 3 signes cliniques caractéristiques de la maladie. Le fait de considérer la FA comme une maladie mineure, la faible connaissance des sources, des réservoirs et du mode de contamination du virus aphteux par toute la chaine de valeur bovine, expliquent l’endémicité de la maladie dans ces zones.Mots clés : Prévalence, facteurs de risque, fièvre aphteuse bovine, Garoua-Boulai, Lom et Djerem.

Cassava is one of the main food crops in Africa, particularly in Côte d'Ivoire. However, the cultivated varieties are prone to attack by diseases. The present work focused on the role of phenolic and in particular flavonoid resistance markers in the Manihot esculenta-Colletotrichum gloeosporioides pathosystem. The aim was to elucidate the involvement of flavonoid antibiosis in the natural defense of three cultivars of M. esculenta when confronted with attacks by C. gloeosporioides. The quantitative dosage approach for total phenolics and flavonoids as well as the identification of flavonoid antibiosis have been carried out. The results revealed that the cultivars 9620A, TMS30572 and YACE of M. esculenta have, after the C. gloeosporioides inoculation tests, reacted early 2 days after inoculation (JAI) and accumulated relatively high levels of antibiosis phenolic and flavonoid 9JAI. The three cultivars accumulated constitutive flavonoid antibiosis and 3 neosynthesized antibiosis from 7JAI to 9JAI. The accumulation of flavonoid antibacterials neosynthesized in the stems and in the leaves testify to the expression of a systemic resistance of the cassava plants. The cultivars 9620A and TMS30572 are more tolerant than cultivar YACE. This study approach has made it possible to discriminate between cultivars and can therefore be used as a complementary selection tool to traditional selection tests.Keywords: Manihot esculenta, anthracnose, flavonoïd antibisis, glyphosate.

Mango decline is a serious disease in production areas in Burkina Faso. The aim of this study was to contribute to the management of the disease through the use of plant aqueous extracts. Antifungal activities of Azadirachta indica, Calotropis procera, Gmelina arborea, Jatropha curcas, Eucalyptus camaldulensis and the synthetic fungicide (Mancozeb) were tested against Lasiodiplodia theobromae and Lasiodiplodia pseudotheobromae associated to mango decline in Burkina Faso. Three different concentrations of leaf extracts which 25%, 50%, 75% and 500 ppm of Mancozeb were tested for their antifungal activity in vitro. The results showed that leaf extracts have an inhibitor effect on the growth of the two Lasiodiplodia species. The aqueous extract of G. arborea was the most effective with average inhibition rates of L. theobromae of 42.62%, 73.84% and 74.23% respectively with the concentrations of 25 g/l, 50 g/l and 75 g/l. The aqueous extract of A. indica against L. pseudotheobromae showed maximum percentage inhibition with 50 g/l of 63.10% and with 75 g/l of 72.02%. Mancozeb completely inhibits the mycelial growth of both species of fungi. Ours findings showed that aqueous extracts from plants could be tried for the eco-friendly management of mango decline pathogens.Keywords: Antifungal, plants extract, Lasiodiplodia spp., mango decline, Burkina Faso.
Non-Positivist ‘Higher Norms’ and ‘Formal’ Positivism: Interpretation of the Ethiopian Criminal Law
Authors: Assefa Simeneh Kiros
Published: February 2021

The criminal law is adopted as a means of achieving the common good; it is interpreted and applied by the court. The judge chooses the type of legal theory and method to employ in the interpretation and application of the criminal law. Such theories may be acquired from higher norms or from the decision of the Supreme Court. Because such choice of theory and method determines the outcome of the case, the judge is also expected to be guided by the doctrines in criminal law inspired by the values of rule of law and respect for fundamental rights, enshrined in the Constitution. This article examines how courts harmonise the application of the positive criminal law with the non-positivist theories of higher norms. After reviewing various criminal rules and their judicial application, it finds that the court applies the criminal law as it is written in disregard of the non-positivist theories of higher norms, at times in contradiction to the basic doctrines of the criminal law itself.
Tax Appeal Proceedings before the Federal Tax Appeal Commission in Ethiopia: Critical Reflections
Authors: Byness Aschalew Ashagre
Published: February 2021

Under the 2016 Federal Tax Administration Proclamation (FTAP), it is by way of appeal that taxpayers reach the judiciary when they can show that the Federal Tax Appeal Commission (FTAC) has committed an error of law.  As far as factual issues are concerned, the decision of the FTAC is thus final and conclusive. Ethiopia’s tax dispute resolution system has made improvements although there has been discontent on the part of taxpayers. This article examines the tax appeal processes at the federal level to see whether the processes enhance fair play between taxpayers and the tax authority. Specifically, the article evaluates whether there are clear and adequate procedural rules that ensure access to justice for aggrieved taxpayers and fair treatment by the Federal Tax Appeal Commission (FTAC). I argue that although there have been certain improvements made by the FTAP (as far as administrative appeal before the FTAC is concerned), there are still some critical shortcomings that have to be reconsidered.
Towards Effective Models and Enforcement of Corporate Social Responsibility in Ethiopia
Authors: Demamu Alemayehu Yismaw
Published: February 2021

Corporate Social Responsibility (CSR) is a concept whereby companies regard stakeholder interests in reaching corporate decisions on voluntary basis. Even though CSR is not alien to Ethiopians who are known for their philanthropic and charitable activities, there is no law that expressly requires CSR standards and thresholds. Provisions of the 1960 Commercial Code and other domestic laws show that Ethiopian companies have the option to comply with CSR in their core business strategy and decision making. To that end, companies, have either individually or at sector level, developed model codes of conduct and guidelines including CSR projects and initiatives. However, these are inadequate and they do not guarantee effective CSR behavior among companies. There is thus the need to adequately integrate CSR practices into their core business decisions, and meet the interests and legitimate expectations of their employees, creditors, customers, local communities, and the environment. I argue that the alternatives to ensure effective CSR regulation in Ethiopia are adopting the Enlightened Shareholder Value (ESV) which recognizes a CSR framework tighter than the existing shareholder primacy model, or the Responsible Stakeholder Model (RSM) which adopts more subtle and lighter principles than stakeholder model to demand CSR compliance.
AfCFTA’s Notification Options to WTO: Enabling Clause or Article XXIV Exception
Authors: Tegegn Yehualashet Tamiru
Published: February 2021

Since the formation of the Organization of African Unity (OAU), African countries envisage regional integration to enhance trade among themselves. This effort was preceded by the formation of the sub-regional economic groups which serve as building blocks towards a larger integration. Africa Continental Free Trade Agreement (hereinafter AfCFTA) came into force in May 2019.  As per the procedural requirements of the WTO, AfCFTA should be notified either to WTO’s Committee on Trade and Development (CTD) if AfCFTA opts to use enabling clause exception; or it should be notified to the Committee on Regional Trade Agreement if AfCFTA opts to use Article XXIV of GATT/WTO exception. This comment examines under which exception AfCFTA should notify its integration. I argue that it is better for AfCFTA to notify its integration under Article XXIV of GATT/WTO to the Committee on Regional Trade Agreement rather than under enabling clause to the Committee on Trade and Development.

Canine cognitive dysfunction patients have reduced total hippocampal volume compared with aging control dogs: A comparative magnetic resonance imaging study
Authors: Dewey Curtis Wells , Rishniw Mark , Johnson Philippa J. , Platt Simon , Robinson Kelsey , Sackman Joseph , O'Donnell Marissa
Published: February 2021

Background: Hippocampal atrophy is a key pathologic and magnetic resonance imaging (MRI) feature of human Alzheimer’s disease (AD). Hippocampal atrophy has not been documented via MRI in canine cognitive dysfunction (CCD), which is considered as the dog model of human AD.Aim: The purpose of this retrospective comparative volumetric MRI study was to compare total hippocampal volumes between successfully aging (control) dogs and dogs diagnosed with CCD.Methods: Mimics® software was used to derive total hippocampal volumes and total brain volumes from the MRI studies of 42 aging dogs (≥ 9 years): 16 dogs diagnosed with CCD and 26 successfully aging controls. Hippocampal volumes were normalized to total brain volume and these values were compared between groups using Mann–Whitney U tests.Results: Total hippocampal volume normalized to total brain volume was significantly less for CCD patients compared with control dogs (p = 0.04).Conclusion: The results of this study suggest that – similar to human AD – hippocampal atrophy is a pathological feature of CCD. This finding has potential importance for both investigating disease mechanisms related to dementia as well as future hippocampal-targeted therapies.
The use of small-bore wire-guided chest drains for the management of feline pyothorax: A retrospective case series
Authors: Del Magno Sara , Foglia Armando , De Bastiani Deborah , Cola Veronica , Pisoni Luciano , Grassato Lisa , Pelizzola Marco , Troia Roberto , Giunti Massimo
Published: February 2021

Background: Pyothorax in cats is routinely managed, at least initially, with thoracic tube placement associated with systemic antimicrobial administration. Traditionally, large-bore trocar-type thoracostomy tubes have preferentially been used for the drainage of thick material from the pleural space. In recent years, the use of small-bore wire-guided thoracic drains has increased in both small animals and in humans. Few studies have highlighted the efficacy of smallbore wire-guided thoracostomy tubes.Aim: The purpose of this study was to describe the use of small-bore wire-guided thoracostomy tubes in feline pyothorax in terms of efficacy, safety, and outcome.Methods: Cats with pyothorax managed with small-bore thoracostomy tubes (SBTTs) (2015–2018) were retrospectively studied. The number of drains inserted, the need for anesthesia and analgesia for chest tube placement and maintenance, and related major and minor complications were reviewed. Clinical data, diagnostic results, treatment, and outcome were recorded.Results: Ten cats were enrolled. Thoracostomy tube placement was unilateral in 7/10 cats, despite the presence of bilateral effusion in 9/10 cats, and required sedation (8/10) or anesthesia (2/10). Three cats experienced minor complications during the chest tube insertion, including self-limiting pneumothorax (1/3) and malpositioning (2/3). One cat had a major complication (non-functional malposition) requiring reposition of the drain. Pain management was adequately achieved using opioids (8/10) or opioids plus nonsteroidal anti-inflammatory drugs (2/10). Partialchest tube occlusion occurred in three cases and it was resolved with lavage. In one case, the occlusion was complete, requiring drain removal. Three out of 10 cats were treated medically, combining thoracostomy tubes and antibiotics, while 7/10 cats underwent surgery. All the cats survived.Conclusion: SBTTs represent a safe and effective option for the initial management of feline pyothorax. In fact, mainly minor complications were reported during insertion and usage. The SBTTs were well tolerated by the cats with a satisfactory performance in terms of exudate drainage in most cases. The combined use of a small-bore thoracostomy drain together with the common practice of surgical treatment might have resulted in the successful management of the cases presented.
Bridgeland Stability Conditions on Fano Threefolds

Published: February 2021

We show the existence of Bridgeland stability conditions on all Fano threefolds, by proving a modified version of a conjecture by Bayer, Toda, and the second author. The key technical ingredient is a strong Bogomolov inequality, proved recently by Chunyi Li. Additionally, we prove the original conjecture for some toric threefolds by using the toric Frobenius morphism.

Wonderful compactifications of Bruhat-Tits buildings
Authors: Remy Bertrand , Thuillier Amaury , Werner Annette
Published: February 2021

Given a split semisimple group over a local field, we consider the maximal Satake-Berkovich compactification of the corresponding Euclidean building. We prove that it can be equivariantly identified with the compactification which we get by embedding the building in the Berkovich analytic space associated to the wonderful compactification of the group. The construction of this embedding map is achieved over a general non-archimedean complete ground field. The relationship between the structures at infinity, one coming from strata of the wonderful compactification and the other from Bruhat-Tits buildings, is also investigated.
Smoothing cones over K3 surfaces

Nous exhibons également plusieurs exemples de singularités affichant des comportements spécifiques, tels que des surfaces dont le cône affine est lissable alors même que le cône projectif ne l'est pas.
Algebraic models of the Euclidean plane
Authors: Blanc Jérémy , Dubouloz Adrien
Published: February 2021

We introduce a new invariant, the real (logarithmic)-Kodaira dimension, that allows to distinguish smooth real algebraic surfaces up to birational diffeomorphism. As an application, we construct infinite families of smooth rational real algebraic surfaces with trivial homology groups, whose real loci are diffeomorphic to $\mathbb{R}^2$, but which are pairwise not birationally diffeomorphic. There are thus infinitely many non-trivial models of the euclidean plane, contrary to the compact case.

Socle pairings on tautological rings
Authors: Janda Felix , Pixton Aaron
Published: February 2021

We study some aspects of the $\lambda_g$ pairing on the tautological ring of $M_g^c$, the moduli space of genus $g$ stable curves of compact type. We consider pairing kappa classes with pure boundary strata, all tautological classes supported on the boundary, or the full tautological ring. We prove that the rank of this restricted pairing is equal in the first two cases and has an explicit formula in terms of partitions, while in the last case the rank increases by precisely the rank of the $\lambda_g\lambda_{g - 1}$ pairing on the tautological ring of $M_g$.

Higher rank sheaves on threefolds and functional equations
Authors: Gholampour Amin , Kool Martijn
Published: February 2021

We consider the moduli space of stable torsion free sheaves of any rank on a smooth projective threefold. The singularity set of a torsion free sheaf is the locus where the sheaf is not locally free. On a threefold it has dimension $\leq 1$. We consider the open subset of moduli space consisting of sheaves with empty or 0-dimensional singularity set. For fixed Chern classes $c_1,c_2$ and summing over $c_3$, we show that the generating function of topological Euler characteristics of these open subsets equals a power of the MacMahon function times a Laurent polynomial. This Laurent polynomial is invariant under $q \leftrightarrow q^{-1}$ (upon replacing $c_1 \leftrightarrow -c_1$). For some choices of $c_1,c_2$ these open subsets equal the entire moduli space. The proof involves wall-crossing from Quot schemes of a higher rank reflexive sheaf to a sublocus of the space of Pandharipande-Thomas pairs. We interpret this sublocus in terms of the singularities of the reflexive sheaf.

Smooth affine group schemes over the dual numbers
Authors: ROMAGNY Matthieu , Tossici Dajano
Published: February 2021

We provide an equivalence between the category of affine, smooth group schemes over the ring of generalized dual numbers $k[I]$, and the category of extensions of the form $1 \to \text{Lie}(G, I) \to E \to G \to 1$ where G is an affine, smooth group scheme over k. Here k is an arbitrary commutative ring and $k[I] = k \oplus I$ with $I^2 = 0$. The equivalence is given by Weil restriction, and we provide a quasi-inverse which we call Weil extension. It is compatible with the exact structures and the $\mathbb{O}_k$-module stack structures on both categories. Our constructions rely on the use of the group algebra scheme of an affine group scheme; we introduce this object and establish its main properties. As an application, we establish a Dieudonné classification for smooth, commutative, unipotent group schemes over $k[I]$.

Nous construisons une équivalence entre la catégorie des schémas en groupes affines et lisses sur l'anneau des nombres duaux généralisés k[I], et la catégorie des extensions de la forme 1 → Lie(G, I) → E → G → 1 où G est un schéma en groupes affine, lisse sur k. Ici k est un anneau commutatif arbitraire et k[I] = k ⊕ I avec I 2 = 0. L'équivalence est donnée par la restriction de Weil, et nous construisons un foncteur quasi-inverse explicite que nous appelons extension de Weil. Ces foncteurs sont compatibles avec les structures exactes et avec les structures de champs en O k-modules des deux catégories. Nos constructions s'appuient sur le schéma en algèbres de groupe d'un schéma en groupes affines, que nous introduisons et dont nous donnons les propriétés principales. En application, nous donnons une classification de Dieudonné pour les schémas en groupes commutatifs, lisses, unipotents sur k[I] lorsque k est un corps parfait.
Weighted Projective Lines and Rational Surface Singularities
Authors: Iyama Osamu , Wemyss Michael
Published: February 2021

In this paper we study rational surface singularities R with star shaped dual graphs, and under very mild assumptions on the self-intersection numbers we give an explicit description of all their special Cohen-Macaulay modules. We do this by realising R as a certain Z-graded Veronese subring S^x of the homogeneous coordinate ring S of the Geigle-Lenzing weighted projective line X, and we realise the special CM modules as explicitly described summands of the canonical tilting bundle on X. We then give a second proof that these are special CM modules by comparing qgr S^x and coh X, and we also give a necessary and sufficient combinatorial criterion for these to be equivalent categories. In turn, we show that qgr S^x is equivalent to qgr of the reconstruction algebra, and that the degree zero piece of the reconstruction algebra coincides with Ringel's canonical algebra. This implies that the reconstruction algebra contains the canonical algebra, and furthermore its qgr category is derived equivalent to the canonical algebra, thus linking the reconstruction algebra of rational surface singularities to the canonical algebra of representation theory.

Automation of Monitoring Students' Knowledge and Independent Work Using Mathcad
Authors: Batova Marina
Published: February 2021

In the challenging Covid-19, and also online education and web-learning expansion conditions, independent and distance forms of student work become especially relevant. As a consequence, the role played by such important parts of the educational process as control and monitoring the knowledge acquisition by students, and also their skills and abilities is growing. In this connection, the need to provide the educational process with a large number of individual variants of tasks, both training tasks and control tests, has increased. In addition, in this case a teacher faces the problem on performing such timeconsuming work as quick checking and evaluating a large number of tasks completed by students, and also monitoring their knowledge and skills. To solve these problems, the paper offers an automated method for creating and checking tasks and tests using Mathcad software. Implementation of this method is shown by an example of topics studied in the courses "Econometrics" and "Mathematical Statistics". The author has a patent issued by the Federal Service for Intellectual Property of the Russian Federation for the developed algorithm.

This paper explores historical engagement in priestly formation in Indonesia by the Vincentians, the Catholic Religious Congregation, who has been sent to a mission in Indonesia (from the Netherlands) and erected the Diocese of Surabaya since 1923. The paper outlines the Vincentian missionaries’ theological understanding of mission and the importance of establishing minor and major seminary to train the indigenous candidates for the priesthood to take care of their local churches. This study's methodology applies a historical approach to see the strategies of the Vincentians to develop the formation of priestly candidates related to the challenges of the times. From this study, we found that the history of the Catholic mission has a meaningful peak in planting the Church as often produced in the mission and the formation of its local priests. The education of candidates for the priesthood is not just a form of apostolic work but is essentially a necessary part of the Catholic Church's mission. The Vincentians have carved a hard work of mission apostolates in the establishment of the Diocese of Surabaya with its charismatic works and the education of its laymen until today and especially in the continual engagement in the priestly formation in Indonesia with its changing challenges. The excellent form of the Catholic priests is essential to the mission, as the candidates will be the future leaders of the local Church and the preachers of the Gospel wherever they are sent.
