Examens préliminaires à la Cour pénale internationale : fondements juridiques, pratique du Bureau de la Procureure et développements judiciaires
Authors: Amoulgam Azé Kerté 
Published: July 2020

Les examens préliminaires occupent une place importante dans la procédure pénale de la Cour pénale internationale, car ils permettent de déterminer les situations qui feront l’objet d’enquête et de poursuites. Ils sont menés en toute discrétion par le Bureau de la Procureure. La Procureure peut engager des examens préliminaires de sa propre initiative ou à partir d’un renvoi d’un État partie ou du Conseil de sécurité de l’Organisation des Nations unies. Ces examens préliminaires portent sur une situation et débouchent, après le test de compétence, de recevabilité et des intérêts de la justice, sur une décision de la Procureure sur l’opportunité d’ouvrir ou non une enquête. Selon le mode de saisine et la nature de sa décision, la Procureure sera contrainte ou non de demander l’autorisation de la Chambre préliminaire avant de procéder à l’enquête. La Chambre préliminaire exerce deux types de contrôle sur la décision de la Procureure : un contrôle absolu lorsque la Procureure décide de passer à l’étape d’enquête de sa propre initiative ou lorsqu’elle refuse d’enquêter car il en est dans l’intérêt de la justice, et un contrôle souple lorsque la Procureure décide de ne pas enquêter après un renvoi. Le Bureau de la Procureure fait face à des choix difficiles et à des critiques dans sa manière de conduire les examens préliminaires, en lien notamment avec leur durée, leur publicisation, leur rôle, leur contrôle et leur traitement.

This research was proposed to evaluate the results under different spacing and densities arrangements on growth, development and productivity of peanut plants, cultivate BR-1, in an agricultural area on the banks of the Piranhas River, located in the municipality of Pombal-PB. Therefore, the study was developed in the experimental field, of the Agri-Food Science and Technology Center, located in São João farm, distant 18 kilometers from the city Pombal. This experiment was carried out from february to may/2017 as a factorial experiment laid out in Complete Randomized Block Design (CRBD), with six repetitions. Include two factors, spaces (0.10x 0.50 m and 0.20x 0.50 m) and density (one seed per hole and two seeds per hole) totaling 24 plots. The experimental unit was composed of three lines of 4 m, the central line being considered a useful area. Regardless of the sowing season, plant density or spacing are factors that most influence agronomic characteristics and pod productivity and grains of peanuts grown in the Sertao Paraibano. The number of immature fruits per plant was the only variable that significantly differed from the cultivation arrangements in relation to the others, showing better behaviors in the highest density of plants per hectare and in the largest spacing. Regardless of the sowing season, plant density or spacing are factors that most influence agronomic characteristics and in the productivity of pods and grains of peanuts grown in the Sertao Paraibano.

Published: July 2020

The need of energy never comes to an end so; the challenge is to procure power source sufficient to offer for our energy needs. Besides, this energy source must be dependable, renewable, recurring and non-contributing to climate change.
Aims: This study was aimed to produce biodiesel from Roselle seed oil and to investigate its quality. Methodology: The Roselle seeds were clean from dirt, milled to proper size and the oil was extracted using soxhlet with n-hexane as solvent. The extracted oil was subjected to physiochemical analysis tests and then transesterified using methanol and potassium hydroxide as catalyst; with ratio of oil to alcohol 1:8 at 65°C. The quality of produced biodiesel was investigated and compared to international standards. The fatty acid composition of the produced biodiesel was determined by GC-MS.
Results: Based on the experimental results, the yellow with characteristic odor oil was obtained from the seeds had the following physicochemical properties: yield, 12.65%; refractive index (25°C), 1.467 m ; free fatty acids, 5.5%; saponification value, 252 mg KOH/g of oil; density, 0.915 g/mL and ester value, 241 mgKOH/g. Also the biodiesel yield achieved was 96%, with density, 0.80 g/mL; API, 44.63; Kinematics viscosity @ 40˚C, 0.742; Pour point, < -51˚C; and Micro Carbon Residual (MCR), 0.65%; which conformed to the range of ASTM D6751 and EN 14214 standard specifications. However, the GC-MS analysis result revealed that the biodiesel produced was methyl ester and free other undesired products such as linoleic acid (33%), elaidic acid (29%) and palmitic acid (17%) and other biomolecules.
Conclusion: Based on the obtained results, Roselle seed oil had potential for biodiesel production due to its high contains of free fatty acids. Therefore, in the future, more investigations in alcohol: oil ratio and the concentration of catalyst may be warranted to increase the yield much more.

Aims: In traditional medicine, several plant species from Rutaceae’s family have been used to treat sickle cell anemia. However, more studies are needed to corroborate the antisickling activity of Zanthoxylum leprieurii species. The objective of this paper was to evaluate the sickling cell inhibition and radical scavenging activities of hydroethanolic and aqueous extracts of Zanthoxylum leprieurii’s bark, a plant species used in the management of sickle cell anemia in eastern Côte d’Ivoire.
Methods: Hydroethanolic and aqueous extracts of the stem bark of Zanthoxylum leprieurii were prepared. Qualitative and quantitative phytochemical tests were carried out. In addition, diphenyl 1, 2 picrylhydrazyl (DPPH) was used to determine the antioxidant potential of these two extracts. The antisickling activity of two extracts was determined by the Emmel method.
Results and Discussion: Zanthoxylum leprieurii’s barkextracts have demonstrated antioxidant property. The IC50 value of the hydroethanolic extract (0.308±0.06) was lower than that of the decocted (0.434 ±0.06). At 10 mg/mL, the sickling cell inhibition of DZL was 81% ±2.66 while EZL was 89% ±0.44. The presence of alkaloids, sterols, Polyterpenes and phenolic compounds in both extracts could explain the sickling inhibition activity of these extracts. All the extracts revealed an antioxidant and antisickling activities higher than the standard.
Conclusion: The hydroethanolic extract (EZL) demonstrated a higher antisickling activity and exhibited a better free radical scavenging activity. The use of Zanthoxylum leprieurii’s bark in the traditional management of sickle cell anemia is justified.

AbstractThe gut–brain axis has attracted increasing attention in recent years, fueled by accumulating symptomatic, physiological, and pathological findings. In this study, the aggregation and toxicity of amyloid beta (Aβ), the pathogenic peptide associated with Alzheimer's disease (AD), seeded by FapC amyloid fragments (FapCS) of Pseudomonas aeruginosa that colonizes the gut microbiome through infections are examined. FapCS display favorable binding with Aβ and a catalytic capacity in seeding the peptide amyloidosis. Upon seeding, twisted Aβ fibrils assume a much‐shortened periodicity approximating that of FapC fibrils, accompanied by a 37% sharp rise in the fibrillar diameter, compared with the control. The robust seeding capacity for Aβ by FapCS and the biofilm fragments derived from P. aeruginosa entail abnormal behavior pathology and immunohistology, as well as impaired cognitive function of zebrafish. Together, the data offer the first concrete evidence of structural integration and inheritance in peptide cross‐seeding, a crucial knowledge gap in understanding the pathological correlations between different amyloid diseases. The catalytic role of infectious bacteria in promoting Aβ amyloidosis may be exploited as a potential therapeutic target, while the altered mesoscopic signatures of Aβ fibrils may serve as a prototype for molecular assembly and a biomarker for screening bacterial infections in AD.
CsZn2BO3X2 (X2=F2, Cl2, and FCl): A Series of Beryllium‐Free Deep‐Ultraviolet Nonlinear‐Optical Crystals with Excellent Properties

Published: July 2020

AbstractDesigning deep‐ultraviolet (DUV) nonlinear‐optical (NLO) crystals is one of the major current research interests, but it faces a great challenge. In order to overcome the problem of crystal growth and the toxicity of BeO raw materials in KBe2BO3F2 (KBBF), the only applicable DUV NLO crystal so far, we substitute Be2+ cations with Zn2+ in the KBBF structure and modify the halogen anions, by which three new Zn‐containing KBBF‐like compounds, CsZn2BO3X2 (X2=F2, Cl2, and FCl), have been successfully synthesized. They all exhibit excellent NLO properties, including improved SHG responses (2.8–3.5×KDP) and short UV cut‐off edges (<190 nm). In comparison with KBBF, CsZn2BO3X2 (X2=F2, Cl2, and FCl) are all chemically benign and have better growth habits, so they are all promising as DUV NLO crystals. Further study on structure–property relationships indicates that the mixing of halogen anions is a feasible strategy to enhance the SHG responses of the KBBF family.

Published: July 2020

AbstractThe discovery of chemical methods enabling the construction of carbocycle‐fused uracils which embody a three‐dimensional and functional‐group‐rich architecture is a useful tool in medicinal chemistry oriented synthesis. In this work, an unprecedented amine‐catalyzed [4+2] cross‐cycloaddition is documented; it involves remotely enolizable 6‐methyluracil‐5‐carbaldehydes and β‐aryl enals, and chemoselectively produces two novel bicyclic and tricyclic fused uracil chemotypes in good yields with a maximum level of enantiocontrol. In‐depth mechanistic investigations and control experiments support an intriguing homo‐synergistic organocatalytic approach, where the same amine organocatalyst concomitantly engages both aldehyde partners in a stepwise eliminative [4+2] cycloaddition, whose vinylogous iminium ion intermediate product may diverge—depending upon conditions—to either bicyclic targets by hydrolysis or tricyclic products by a second homo‐synergistic trienamine‐mediated stepwise [4+2] cycloaddition.
A common grade table inspiring meaningful feedback
Authors: Harrison Frank 
Published: July 2020

AbstractThe use of the 1–4 grading scale is gaining popularity as schools transition to competency‐based education. However, independent interpretations and percentage conversions have led to general confusion and sometimes outright rejection of competency‐based assessment. The first step to establish clear communication is to anchor the existing four‐point GPA scale in cognitive performance, which provides a strong framework for improved student engagement. Applied research into the learning brain is shifting classroom expectations to actively engage learners with stimulating cognitive challenges, such as synthesis and creative transfer. When the cognitive performance curve is consistently applied in the development of assessment rubrics, educators will provide stronger analytical feedback through meaningful common grades.
