Authors: Clark David L. , Wiegert Paul A. , Brown Peter G. , Vida Denis , Heinze Aren , Denneau Larry 
Published: June 2023

Abstract
On 2020 September 18 U.S. Government (USG) sensors detected a bolide with peak bolometric magnitude of −19 over the Western Pacific. The impact was also detected by the Geostationary Lightning Mapper instrument on the GOES-17 satellite and infrasound sensors in Hawaii. The USG measurements reported a steep entry angle of 67° from horizontal from a radiant 13° east of north and an impact speed of 11.7 km s−1. Interpretation of all energy yields produces a preferred energy estimate of 0.4 kt TNT, corresponding to a 23,000 kg, 3 m diameter meteoroid. A postimpact search of telescopic images found that the Asteroid Terrestrial-impact Last Alert System survey captured the object just 10 minutes prior to impact at an Earth-centered distance of nearly 11,900 km with apparent magnitude m = 12.5. The object appears as a 0.44° streak originating on the eastern edge of the image, extending one-third of the USG state-vector-based prediction of 1.26° over the 30 s exposure. The streak shows brightness variability consistent with small asteroid rotation. The position of Earth’s shadow, the object’s size, and its consistency with the reported USG state vector confirm the object is likely natural. This is the eighth preatmospheric detection of a near-Earth asteroid (NEA) impactor and the closest initial telescopic detection prior to impact. The high altitude of peak fireball brightness suggests it was a weak object comparable in many respects with 2008 TC3 (the Almahata Sitta meteorite), with an absolute magnitude H = 32.5 and likely low albedo. Therefore, we suggest the NEA was a C-complex asteroid.
Éthique et soin

Published: June 2023

Si le terme « mourant » semble insaisissable et impensable, et se révèle être une incohérence et une antinomie, comment saisir le sens, la temporalité et les enjeux éthiques et ontologiques de son usage en fin de vie ? Faut-il voir dans l’usage de ce terme en fin de vie un pis-aller symbolisant la difficulté conceptuelle à penser et à déterminer cette temporalité de l’existence et l’intrusion d’un état existentiel de mort dans la vie ?
La quadrature du cercle. Commun, communauté et immunité
Authors: Kaufmann Laurence 
Published: June 2023

Pour explorer la question du bien commun, il n’est jamais inutile de revenir aux enjeux et aux origines de la notion de communauté. Après avoir comparé les formes sociales et politiques mais aussi géométriques de la « communauté » et de la « société », cet article se penche sur la distinction entre communauté et immunité que propose Roberto Esposito. Une fois déployée l’identité catégorielle, et non pas relationnelle, qu’implique la déclinaison « immunitaire » de la communauté, il s’agira de proposer une conception plus réaliste et plus obligeante du co-munus . Une telle conception fait miroiter une autre forme sociale que celle, pesante, du cercle qui attache et enferme la « communauté » ou que celle, superficielle, de la ligne qui traverse et fissure la « société » : celle, triangulaire , du « public » et de la voie des « communs » qu’il est susceptible de creuser, entre la propriété privée et l’État souverain.
La ville entre innovation sociale et « communification »
Authors: Festa Daniela 
Published: June 2023

Les communs n’ont pas été seulement un mouvement d’en bas pour réclamer des espaces et des ressources matérielles et symboliques. Ils ont marqué également un changement profond dans la façon dont nous concevons la ville et ses institutions. Inscrits dans un long processus de transformation de l’identité urbaine de plus en plus caractérisée par une multiplicité d’acteurs et de stratégies, les communs ont ainsi influencé les politiques urbaines par des voies différenciées, parfois composites, parfois divergentes. Cette contribution analyse des différents chemins qui ont conduit en Italie et, plus largement en Europe, à l’émergence de ladite « commonification » des politiques urbaines et locales en mettant en évidence des effets à la fois innovants et ambivalents.
Le corps-continent
Authors: Vanderberghe Frédéric 
Published: June 2023

Dans la tradition de Marcel Mauss et de Georg Simmel, David Le Breton analyse le corps comme un « fait social total ». Sa socio-anthropologie du corps est à la fois une anthropologie philosophique, symbolique et existentielle de l’être-au-monde, une sociologie interactionniste de l’action et une sociologie critique de la modernité. En explorant toutes les facettes de son œuvre foisonnante sur le corps, les émotions, les sensations, l’identité, la douleur, le risque, les jeunes, etc., l’article brosse un portrait émouvant de David Le Breton dans tous ses états.

Authors: Gibson Jesse E. , Campbell Teisha , Gibson Kyle , Kottemann Kim , Krause Morgan A. , Pack Leigh 
Published: June 2023

Background
Although a shortage of organ donors is a continuing global problem in health care, obtaining authorization for donation after an individual experiences a traumatic nonsurvivable event can be difficult.

Objective
To improve organ donation practices at a level II trauma center.

Methods
After reviewing trauma mortality cases and performance improvement metrics with their organ procurement organization’s hospital liaison, leaders at the trauma center implemented a multidisciplinary performance improvement initiative to engage the facility’s donation advisory committee, provide education for staff members, and increase program visibility to create a more donation-friendly culture for the facility.

Results
The initiative led to an improved donation conversion rate and a greater number of organs procured. Continued education increased staff and provider awareness of organ donation, contributing to the positive outcomes.

Conclusion
A multidisciplinary initiative that includes continuing staff education can improve organ donation practices and program visibility, ultimately benefiting patients in need of organ transplantation.
Human IL-35 Inhibits the Bioactivity of IL-12 and Its Interaction with IL-12Rβ2

Published: June 2023

Abstract
IL-35 is an immunosuppressive cytokine with roles in cancer, autoimmunity, and infectious disease. In the conventional model of IL-35 biology, the p35 and Ebi3 domains of this cytokine interact with IL-12Rβ2 and gp130, respectively, on the cell surface of regulatory T and regulatory B cells, triggering their suppression of Th cell activity. Here we use a human IL-12 bioactivity reporter cell line, protein binding assays, and primary human Th cells to demonstrate an additional mechanism by which IL-35 suppresses Th cell activity, wherein IL-35 directly inhibits the association of IL-12 with its surface receptor IL-12Rβ2 and downstream IL-12–dependent activities. IL-12 binding to the surface receptor IL-12Rβ1 was unaffected by IL-35. These data demonstrate that in addition to acting via regulatory T and regulatory B cells, human IL-35 can also directly suppress IL-12 bioactivity and its interaction with IL-12Rβ2.
Nigerian State, Leadership Deficiency and the Challenges of Good Governance in the Fourth Republic.
Authors: Lawal Tolu , Oriola Sesan 
Published: June 2023

State is essentially created to provide and sustain good governance for its citizenry. The ability of the state to fulfill this fundamental responsibility is greatly depended on the physical, social and political capacity of the leaders entrusted with the management of the affairs of the state. Significantly, the nature and quality of leadership and governance in any state determines to a large extent how such state will be socially described, politically evaluated and economically rated among the comity of nations within the global community. Consequently, every state strives to ensure that its leadership recruitment processes is jealously guided and protected by the essential qualities capable of engendering good governance and ensuring effective service delivery system. Nigerian state has been battling with leadership and governance crisis since independence without any strong hope of surmounting these unending challenges as poverty, insecurity, corruption and the like continued unabated. With this ugly and unceasing situation, one is forced to ask the following questions; one, despite various policy attempts and ceaseless use of resources at ensuring good governance by successive governments in Nigeria, why has it been so difficult to achieve? to what has been responsible for this never-ending leadership debacle in Nigeria in spite of series of implemented reforms on leadership recruitment? Based on the foregoing, the study examined critically leadership recruitment and governance processes in Nigeria with the intention of identifying the various factors that are strongly responsible for leadership deficiency and the apparent failure of governance in the last decades. The study adopted Elite theory for its analysis. The study employed the use of existing data from texts, journals, magazines, conference proceedings, newspapers, bulletins, published and unpublished theses and the internet to source its information. The study observed that leadership deficiency has been responsible for governance crisis in Nigeria, and therefore recommended cultivation of public interest, constitutionalism, integrity, accountability and transparency as panacea to good leadership and governance.
Perspectives on the Participation of Civil/Public Servants in Partisan Politics in Nigeria: A Call for Rethinking and Revision of the Public Service Rules
Authors: Abiodun Odusote 
Published: June 2023

Towards the 2023 general elections in Nigeria, the debate on the validity and application of the principle of absolute political neutrality of civil servants resurfaced. This principle requires civil servants to abstain from political activities including campaigning and joining political parties. The Federal Civil Service Commission and the Attorney General of the Federation contend that the Public Service Rules prohibit civil servants from political activities. However, the Nigeria Labour Congress and other labour unions disagree and argue that the Public Service Rules contravene the constitution and violate civil servants' fundamental rights to freely associate and belong to a political party. This study interrogates the legality and desirability of the principle of absolute political neutrality in the Nigerian Civil Service. It draws upon the extant statutory framework, relevant jurisprudence, scholarly literature and contemporary practices in other jurisdictions. The finding of this study shows that the Public Service Rules as presently constituted violate constitutional provisions and civil servants' rights to hold and join political parties of their choice. The central argument is that constitutionalism principles in Nigeria and practices in other jurisdictions increasingly invalidate an approach that anchored civil servant loyalty and effectiveness on the principle of absolute political neutrality. The study concludes by recommending that in line with practices in the United Kingdom and Canada, the Civil Service Rules should be revised to permit differentiated prohibitions. This will permit civil servants that hold non-sensitive positions to hold political opinions and join political parties of their respective choice.

Published: June 2023

Benzimidazole is one of the privileged nitrogen-containing heterocyclic compounds, which is found in many bioactive compounds, benzimidazole and its derivatives have evolved as an important heterocyclic system due to their potency in a wide range of biologically active compounds like anthelmintic, antibacterial, antifungals, anti-inflammatory, antiviral, and so on. Derivatives of 1-arylsulfonylbenzimidazole and their respective Cu (II), Ni (II) and Co (II) complexes were successfully synthesized. The structures of all the synthesized ligands were confirmed by using IR, UV-Visible, 1H NMR, and 13C NMR spectroscopy. The Cu (II), Ni (II) and Co (II) complexes were confirmed by using IR and VU-Visible spectra. The IR spectra of ligands and its metal complexes imply that the benzimidazol derivative ligands behave as basic bidentate ligands coordination through the azomethine nitrogen and oxygen atom. In-vitro antibacterial activity of all the synthesized ligands and their metal complexes were evaluated by using disc diffusion method against K. pneumoniae, E. coli, and S. aureus bacterial species .The tested compounds and metal complexes exhibited from good to excellent activity (zone of inhibition (ZI) ranged 10 mm to 23 mm). Compound BIL1 exhibited better activity than the standard drug against E. coli (ZI of 15 mm) and K. pneumoniae (ZI of 5 mm)compared with gentamycin ((ZI of 15mm). Complex CoC exhibited better activity against S. aureus (ZI of 23 mm) compared with gentamicine (ZI value of 21 mm). This compound is a good starting point to develop new drug for treating pathogenic diseases. Therefore, synthesis of more analogue were recommended for further discovery of a new drug candidate.

Dans le but de soutenir la production du maïs sur un Arenosol, une étude a été conduite pendant la première campagne agricole 2016-2017 sur un Arenosol en République démocratique du Congo en vue d’évaluer les effets des feuilles de Tithonia diversifolia, du fumier de vache, de la chaux et des engrais inorganiques (NPK) sur le rendement de maïs et la rentabilité économique. L’essai a été conduit suivant un dispositif en bloc complet randomisé avec dix traitements : T0= témoin ; T1=Fumier de vache ; T2=Guano; T3=Feuilles de Tithonia diversifolia ; T4=Engrais NPK 17-17-17; T5= Feuilles de Tithonia diversifolia + Chaux; T6=Fumier de vache + chaux; T7=Guano + Chaux; T8=Engrais NPK 17-17-17 + Chaux et T9=Chaux. Des effets significatifs des traitements ont été observé sur la croissance des plants, le rendement grains et les marges bénéficiaires. Les traitements T3 et T5 ont donné les meilleurs rendements. Cependant, le traitement T3 révèle un bénéfice brut et l’indice d’acceptabilité (IA) les plus élevés et peut alors être proposé aux agriculteurs avec plus de chance d’adoption.
In order to support the production of maize at an Arenosol a study was conducted during the first cropping season 2016-2017 on an Arenosol in the Democratic Republic of Congo to evaluate the effects of Tithonia diversifolia leaves, cow manure, lime and inorganic fertilizer (NPK) on maize yield and economic profitability. The trial was conducted in a randomized complete block design with ten treatments: T0 = Control; T1 = Cow manure; T2 = Guano; T3 = Tithonia diversifolia leaves; T4 = NPK fertilizer 17-17-17; T5 = Tithonia diversifolia leaves + Lime; T6 = Cow manure + Lime; T7 = Guano + Lime; T8=NPK fertilizer 17-17-17 + Lime and T9=Lime. Significant effects of treatments were observed on plant growth, grain yield and profit margins. Treatments T3 and T5 gave the best yields. However, the T3 treatment showed the highest gross profit and acceptability index (AI) and can then be proposed to farmers with more chance of adoption.

Corchorus olitorius, est une plante de la famille des malvacées, connue sous l’appellation de « kroala » en Côte d’Ivoire. Cette plante est reconnue comme riche en substances bioactives et nutritives. Elle possède également des propriétés pharmacologiques. Dans le but d’identifier et valoriser les cultivars du Corchorus olitorius, une enquête ethnobotanique transversale basée sur un échantillonnage de type boule de neige a été réalisée dans les différentes régions centres de la Côte d’Ivoire afin d’inventorier les cultivars de Corchorus olitorius ainsi que les usages ethnobotaniques. Au total 17 localités ont été prospectées et l’enquête a porté sur 428 personnes. Il ressort de cette étude que trois (3) cultivars de Corchorus olitorius var olitorius et deux (2) cultivars de Corchorus olitorius var incisifolius ont été identifiés. Ces cultivars sont utilisés occasionnellement que pour la consommation alimentaire. Seulement 17,3% des enquêtés affirment que les feuilles de kroala soigneraient certaines maladies telles que l’anémie, la fièvre typhoïde, la constipation et le paludisme. Une meilleure connaissance des propriétés biochimiques et phytochimiques de ces cultivars contribuera à une meilleure valorisation de cette plante aussi bien à travers l’alimentation que la santé des populations.

It also has pharmacological properties. In order to identify and valorize the cultivars of Corchorus olitorius, a cross-sectional ethnobotanical survey based on a snowball sampling was carried out in the different central regions of Côte d'Ivoire in order to inventory the cultivars of Corchorus olitorius as well as the ethnobotanical uses. A total of 17 localities were surveyed and 428 people were interviewed. The study revealed that three (3) cultivars of Corchorus olitorius var olitorius and two (2) cultivars of Corchorus olitorius var incisifolius were identified. These cultivars are used occasionally only for food consumption. Only 17.3% of the respondents claimed that kroala leaves would treat certain diseases such as anemia, typhoid fever, constipation and malaria. A better knowledge of the biochemical and phytochemical properties of these cultivars will contribute to a better valorization of this plant both through food and health of the populations.

Breast cancer is the second major cause of death in the world. Breast cancer accounts for 16% of all cancer deaths worldwide. Most of the methods of detecting breast cancer very expensive and difficult such as mammography. The objective of this research paper is detecting breast cancer through blood analysis using J48 algorithm which will serve as alternative to these expensive methods.
The J48 algorithm was used to classify 116 instances also,10-fold cross validation and holdout procedure were used coupled changing of random seed. Average accuracies of 84.65% and 89.99% were acquired for cross validation and holdout procedure. Although it was also discovered that Blood Glucose level is a major determinant in detecting breast cancer, it has to be combined with other attributes to make decision as a result of other health issues such as diabetes.
