Modification of the genetic background and, in some cases, the introduction of targeted mutations can play a critical role in producing trait characteristics during the breeding of crops, livestock, and microorganisms. However, the question of how similar trait characteristics emerge when the same target mutation is introduced into different genetic backgrounds is unclear. In a previous study, we performed genome editing of AWA1, CAR1, MDE1, and FAS2 on the standard sake yeast strain Kyokai No. 7 to breed a sake yeast with multiple excellent brewing characteristics. By introducing the same targeted mutations into other pedigreed sake yeast strains, such as Kyokai strains No. 6, No. 9, and No. 10, we were able to create sake yeasts with the same excellent brewing characteristics. However, we found that other components of sake made by the genome-edited yeast strains did not change in the exact same way. For example, amino acid and isobutanol contents differed among the strain backgrounds. We also showed that changes in yeast cell morphology induced by the targeted mutations also differed depending on the strain backgrounds. The number of commonly changed morphological parameters was limited. Thus, divergent characteristics were produced by the targeted mutations in pedigreed sake yeast strains, suggesting a breeding strategy to generate a variety of sake yeasts with excellent brewing characteristics.
Emergence of a Hybrid IncI1-Iα Plasmid-Encoded blaCTX-M-101 Conferring Resistance to Cephalosporins in Salmonella enterica Serovar Enteritidis
Authors: Qin Xiaojie , Zhang Zengfeng
Published: May 2023

The increasing resistance to cephalosporins in Salmonella poses a serious threat to public health. In our previous study, the blaCTX-M-101 gene, a new blaCTX-M variant, was first reported in Salmonella enterica serovar Enteritidis (S. Enteritidis). Here, we further analyzed the genome characterization, transferability, and resistance mechanism of one S. Enteritidis isolate (SJTUF14523) carrying blaCTX-M-101 from an outpatient in 2016 in Xinjiang, China. This strain was a multidrug resistance (MDR) isolate and exhibited resistance to ceftazidime (MIC = 64 μg/mL), cefotaxime (MIC = 256 μg/mL), and cefepime (MIC = 16 μg/mL). Phylogenetic analysis revealed that SJTUF14523 had a close relationship to another S. Enteritidis isolate from the United States. In the presence of plasmid p14523A, there were 8- and 2133-fold increases in the MICs of cephalosporins in Escherichia coli C600 in the conjugation. Gene cloning results indicated that blaCTX-M-101 was the decisive mechanism leading to ceftazidime and cefotaxime resistance that could make the MICs break through the resistance breakpoint. Plasmid sequencing revealed that the blaCTX-M-101 gene was located on an IncI1-Iα transferable plasmid (p14523A) that was 85,862 bp in length. Sequence comparison showed that p14523A was a novel hybrid plasmid that might have resulted from the interaction between a homologous region. Furthermore, we found a composite transposon unit composed of ISEcp1, blaCTX-M-101, and orf477 in p14523A. ISEcp1-mediated transposition was likely to play a key role in the horizontal transfer of blaCTX-M-101 among plasmids in S. Enteritidis. Collectively, these findings underline further challenges in the prevention and control of antibiotic resistance posed by new CTX-M-101-like variants in Salmonella.
Ru-Controlled Thymine Tautomerization Frozen by a k1(O)-, k2(N,O)-Metallacycle: An Experimental and Theoretical Approach

Published: May 2023

The reaction of mer-(Ru(H)2(CO)(PPh3)3) (1) with one equivalent of thymine acetic acid (THAcH) unexpectedly produces the macrocyclic dimer k1(O), k2(N,O)-(Ru(CO)(PPh3)2THAc)2 (4) and, concomitantly, the doubly coordinated species k1(O), k2(O,O)-(Ru(CO)(PPh3)2THAc) (5). The reaction promptly forms a complicated mixture of Ru-coordinated mononuclear species. With the aim of shedding some light in this context, two plausible reaction paths were proposed by attributing the isolated or spectroscopically intercepted intermediates on the basis of DFT-calculated energetic considerations. The cleavage of the sterically demanding equatorial phosphine in the mer-species releases enough energy to enable self-aggregation, producing the stable, symmetric 14-membered binuclear macrocycle of 4. The k1-acetate iminol (C=N-OH) unit of the mer-tautomer k1(O)-(Ru(CO)(PPh3)2(THAc)) (2) likely exhibits a stronger nucleophilic aptitude than the prevalent N(H)-C(O) amido species, thus accomplishing extra stabilization through concomitant k2(N,O)-thymine heteroleptic side-chelation. Furthermore, both the ESI-Ms and IR simulation spectra validated the related dimeric arrangement in solution, in agreement with the X-ray determination of the structure. The latter showed tautomerization to the iminol form. The 1H NMR spectra in chlorinated solvents of the kinetic mixture showed the simultaneous presence of 4 and the doubly coordinated 5, in rather similar amounts. THAcH added in excess preferentially reacts with 2 or trans-k2(O,O)-(RuH(CO)(PPh3)2THAc) (3) rather than attacking the starting Complex 1, promptly forming the species of 5. The proposed reaction paths were inferred by spectroscopically monitoring the intermediate species, for which the results were strongly dependent on the of conditions the reaction (stoichiometry, solvent polarity, time, and the concentration of the mixture). The selected mechanism proved to be more reliable, due to the final dimeric product stereochemistry.

Published: May 2023

Lomentospora prolificans is a pathogenic and multidrug-resistant fungus that can infect both immunocompetent and immunocompromised patients, with mortality rates up to 87%. The World Health Organization (WHO) included this fungal species in its first list of 19 priority fungal pathogens, which focused on fungal pathogens that can cause invasive acute and subacute systemic fungal infections. Therefore, there is a growing interest in finding new therapeutic alternatives. In this work, the synthesis of twelve α-aminophosphonates by the microwave-assisted Kabachnik–Fields reaction and twelve α-aminophosphonic acids by a monohydrolysis reaction is reported. All compounds were evaluated by the agar diffusion method as a preliminary screening in comparison with voriconazole, showing inhibition halos for compounds 7, 11, 13, 22 and 27. The five active compounds in the preliminary tests were evaluated against five strains of L. prolificans following protocol M38-A2 from CLSI. The results showed that these compounds exhibit antifungal activity in the concentration range of 900->900 μg/mL. Cytotoxicity against healthy COS-7 cells was also evaluated by the MTT assay, and it was shown that compound 22 was the least cytotoxic, with a viability of 67.91%, comparable to the viability exhibited by voriconazole (68.55%). Docking studies showed that the possible mechanism of action of the active compounds could be through the inhibition of the enzyme lanosterol-14-alpha-demethylase in an allosteric hydrophobic cavity.
Review of 2 × 2 Silicon Photonic Switches
Authors: Yue Wencheng , Cai Yan , Yu Mingbin
Published: May 2023

With the advent of 5G, artificial intelligence (AI), Internet of Things (IoT), cloud computing, Internet plus, and so on, data traffic is exploding and higher requirements are put forward for information transmission and switching. Traditional switching requires optical/electrical/optical conversions, which brings additional power consumption and requires the deployment of large amounts of cooling equipment. This increases the cost and complexity of the system. Moreover, limited by the electronic bottleneck, electrical switching will suffer from many problems such as bandwidth, delay, crosstalk, and so on, with the continuous reduction in device footprint. Optical switching does not require optical/electrical/optical conversions and has lower power consumption, larger capacity, and lower cost. Silicon photonic switches received much attention because of their compatibility with the complementary metal-oxide-semiconductor (CMOS) process and are anticipated to be potential candidates to replace electrical switches in many applications such as data center and telecommunication networks. 2 × 2 silicon photonic switches are the basic components to build the large-scale optical switching matrices. Thus, this review article mainly focuses on the principle and state of the art of 2 × 2 silicon photonic switches, including electro-optic switches, thermo-optic switches, and nonvolatile silicon photonic switches assisted by phase-change materials.

Published: May 2023

Graphene-on-silicon photodetectors exhibit broadband detection capabilities with high responsivities, surpassing those of their counterpart semiconductors fabricated purely using graphene or Si. In these studies, graphene channels were considered electrically neutral, and signal amplification was typically attributed to the photogating effect. By contrast, herein, we show graphene channels to exhibit p-type characteristics using a structure wherein a thin oxide layer insulated the graphene from Si. The p-type carrier concentration is higher (six-times) than the photoaging-induced carrier concentration and dominates the photocurrent. Additionally, we demonstrate photocurrent tunability in the channel. By operating this device under a back-gated bias, photocurrent tuning is realized with not only amplification but also attenuation. Gate amplification produces a current equal to the photogating current at a low bias (0.2 V), and it is approximately two orders of magnitude larger at a bias of 2 V, indicating the operation effectiveness. Meanwhile, photocurrent attenuation enables adjustments in the detector output for compatibility with read-out circuits. A quantification model of gate-dependent currents is further established based on the simulation model used for metal–oxide–semiconductor devices. Thus, this study addresses fundamental issues concerning graphene channels and highlights the potential of such devices as gate-tunable photodetectors in high-performance optoelectronics.

Published: May 2023

Plasmonic surface lattice resonances (SLRs) have endowed plasmonic systems with unprecedently high quality (Q) factors, giving rise to great advantages for light–matter interactions and boosting the developments of nanolaser, photodetector, biosensor and so on. However, it still lacks exploration to develop a strategy for achieving large electric field enhancements (FEs) while maintaining high Q factors of SLRs. Here, we investigate and verify such a strategy by engineering morphologies of plasmonic lattice, in which the influences of geometrical shapes, cross-section areas and structural compositions of particles are investigated. Firstly, we found that the Q factor of a plasmonic SLR is inversely proportional to the square of the cross-section area of the cell particles in the studied cases. Secondly, larger FEs of SLRs appear when the separated cell particles support stronger FEs. By combining these effects of particle morphology, we achieve a plasmonic SLR with Q factor and FE up to 2100 and 592 times, respectively. Additionally, supported by the derived connections between the Q factors and FEs of SLRs and the properties of cell particles, the property optimizations of SLRs can be done by optimizing the separated particles, which are distinctly time-saving in simulations. These results provide a guideline for the design of high-performance optical nanocavities, and can benefit a variety of fields including biosensing, nonlinear optics and quantum information processing.

Authors: Tong Yifei , Wang Miao , Zhou Tong
Published: May 2023

As a critical component for space exploration, navigation, and national defense, array antenna secures an indispensable position in national strategic significance. However, various parts and complex assembly processes make the array antenna hard to meet the assembly standard, which causes repeated rework and delay. To realize the accurate and efficient prediction of the assembly accuracy of array antenna, a prediction method based on an auto-encoder and online sequential kernel extreme learning machine with boosting (Boosting-OSKELM) is proposed in this paper. The method is mainly divided into two steps: Firstly, the auto-encoder with the fine-tuning trick is used for training and representation reduction of the data. Then, the data are taken as the input of Boosting-OSKELM to complete the initial training of the model. When new sample data is generated, Boosting-OSKELM can realize the online correction of the model through rapid iteration. Finally, the test shows that the average MSE of Boosting-OSKELM and ANN is 0.061 and 0.12, and the time consumption is 0.85 s and 15 s, respectively. It means that this method has strong robustness in prediction accuracy and online learning ability, which is conducive to the development of array antenna assembly.
Optimal Selection among Various Three-Phase Four-Wire Back-to-Back (BTB) Converters with Comparative Analysis for Wave Energy Converters
Authors: Roh Chan
Published: May 2023

Wave energy converters are attracting attention as an energy source that can respond to climate change. In order to increase the energy efficiency of the wave energy converters, efficient power converters are also required. The efficient converters require operation at a low switching frequency, which increases the weight and volume of the passive components. Therefore, in this paper, the performance of various types of topologies is compared to select the optimal power converter for wave energy converters. In order to cope with the unbalanced operation and unbalanced load of renewable energy, in this paper, the topology of the four-leg type is analyzed centrally. In addition, the analysis was performed by applying the model predictive control that can quickly respond to the rapid energy change of wave energy. In addition, model predictive control was applied to the four-leg converter analyzed in this paper because it is suitable for application to atypical topologies. For performance analysis of various types of topology, the loss and efficiency of each converter were analyzed by applying a loss analysis model, and output current harmonics and leakage current characteristics, capacitor voltage fluctuation rate, etc., were additionally analyzed at various switching frequencies. In conclusion, the three-level four-leg converter showed up to 2.28% and 2.7% higher efficiency under balanced and unbalanced operating conditions.

Authors: Nguyen Van , Wang San-Lang , Nguyen Anh
Published: May 2023

Hemi-pyocyanin (HPC) is a heterocyclic nitrogenous compound with some reported potential medical effects. The current report aimed to investigate the potential use of organic industrial waste for the production of HPC via microbial fermentation. The novel antidiabetic activity of HPC was also accessed and reported in this work. A peanut oil processing by-product (groundnut cake) was screened as the best substrate for Pseudomonas aeruginosa TUN03 conversion to obtain high-yield HPC. This compound was further produced in a 14 L bioreactor system on a large scale (6 L per pilot) and reached higher productivity (35.1 μg/mL) in a shorter time course of cultivation (8 h) compared to fermentation on a small scale in flasks (19.5 μg/mL; 3 days of fermentation). On assessing its activity, HPC demonstrated potent inhibition against α-glucosidase, an antidiabetic enzyme, with a low IC50 value (0.572 mg/mL) and a maximum inhibition rate of 100%. In an in silico study, HPC was found to inhibit α-glucosidase with a good binding energy score (−9.0 kcal/mol) via interaction with amino acids Lys156, Leu313, and Arg315 at the active site, and three bonds (1 H-acceptor and 2 pi-H) were generated. The data from five Lipkin’s rules and ADMET-based pharmacokinetics and pharmacology revealed that HPC possesses drug-like properties and good ADMET properties within the required allotted limitations. The data obtained in the current work highlighted the potential application of groundnut cakes for the eco-friendly and scaled-up production of HPC, a new anti-α-glucosidase agent that should be further investigated for type 2 diabetes management.

Recently, non-electrolyzed HOCl water has gained the attention of researchers as a new disinfecting agent owing to its high sterilization power, easy accessibility, and safety. Non-electrolyzed HOCl water was developed through mixing at a specific ratio based on hypochlorite and mineral supplements, which revealed a high oxidizing power. In this study, we investigated the effects of non-electrolyzed HOCl water on Helicobacter pylori (H. pylori) infection in C57BL/6 mice over 10 weeks. Mice were divided into three groups: normal control (NC) group supplied with purified water (PW) without infection, PW + H. pylori group supplied with PW after H. pylori infection, and HOCl + H. pylori group supplied with HOCl after H. pylori infection. Our findings demonstrated that the HOCl + H. pylori group greatly inhibited WBC and its differential counts, including total white blood cell (WBC), neutrophils, lymphocytes, monocytes, and eosinophils, when compared to the PW + H. pylori group. Accordingly, the amount of reactive oxygen species and calcium activity significantly decreased in the HOCl + H. pylori group compared to the PW + H. pylori group in both serum and stomach lysates. In contrast, HOCl water treatment enhanced GPx activity compared to PW treatment after H. pylori infection in both serum and stomach lysates. Accordingly, the levels of granulocyte-macrophage colony-stimulating factor, IL-1β, and TNF-α cytokine levels were significantly decreased in the HOCl + H. pylori group compared to those in the PW + H. pylori group in the stomach lysate; however, there was no significant difference in serum. In addition, the expression levels of Bax, MMP-3, MMP-9, and TLR-4 were found to decrease after HOCl water treatment, whereas the expression level of Bcl-2 was found to be enhanced after HOCl water treatment in the stomach lysate. Taken together, our results suggest that drinking non-electrolyzed HOCl water has positive anti-oxidative, anti-inflammatory, and anti-apoptotic effects in H. pylori-infected mice through redox and immune regulation.
Image Stitching Based on Color Difference and KAZE with a Fast Guided Filter
Authors: Zhang Chong , Wang Dejiang , Sun He
Published: May 2023

Image stitching is of great importance for multiple fields such as moving object detection and tracking, ground reconnaissance and augmented reality. To ameliorate the stitching effect and alleviate the mismatch rate, an effective image stitching algorithm based on color difference and an improved KAZE with a fast guided filter is proposed. Firstly, the fast guided filter is introduced to reduce the mismatch rate before feature matching. Secondly, the KAZE algorithm based on improved random sample consensus is used for feature matching. Then, the color difference and brightness difference of the overlapping area are calculated to make an overall adjustment to the original images so as to improve the nonuniformity of the splicing result. Finally, the warped images with color difference compensation are fused to obtain the stitched image. The proposed method is evaluated by both visual effect mapping and quantitative values. In addition, the proposed algorithm is compared with other current popular stitching algorithms. The results show that the proposed algorithm is superior to other algorithms in terms of the quantity of feature point pairs, the matching accuracy, the root mean square error and the mean absolute error.
Modelling and Design of a Dual Depletion PIN Photodiode as Temperature Sensor
Authors: Marques Lameirinhas Ricardo A. , N. Torres João Paulo , P. Correia V. Bernardo Catarina
Published: May 2023

Nowadays, optical systems play an important role in communications. Dual depletion PIN photodiodes are common devices that can operate in different optical bands, depending on the chosen semiconductors. However, since semiconductor properties vary with the surrounding conditions, some optical devices/systems can act as sensors. In this research work, a numerical model is implemented to analyze the frequency response of this kind of structure. It considers both transit time and capacitive effects, and can be applied to compute photodiode frequency response under nonuniform illumination. The InP-In0.53Ga0.47As photodiode is usually used to convert optical into electrical power at wavelengths around 1300 nm (O-band). This model is implemented considering an input frequency variation of up to 100 GHz. The focus of this research work was essentially the determination of the device’s bandwidth from the computed spectra. This was performed at three different temperatures: 275 K, 300 K, and 325 K. The aim of this research work was to analyze if a InP-In0.53Ga0.47As photodiode can act as a temperature sensor, to detect temperature variations. Furthermore, the device dimensions were optimized, to obtain a temperature sensor. The optimized device, for a 6 V applied voltage and an active area of 500 μm2, had a total length of 2.536 μm, in which 53.95% corresponded to the absorption region. In these conditions, if the temperature increases 25 K from the room temperature, one should expect a bandwidth increase of 8.374 GHz, and if it decreases 25 K from that reference, the bandwidth should reduce by 3.620 GHz. This temperature sensor could be incorporated in common InP photonic integrated circuits, which are commonly used in telecommunications.
Evaluation of a Restoration Algorithm Applied to Clipped Tibial Acceleration Signals

Published: May 2023

Wireless accelerometers with various operating ranges have been used to measure tibial acceleration. Accelerometers with a low operating range output distorted signals and have been found to result in inaccurate measurements of peaks. A restoration algorithm using spline interpolation has been proposed to restore the distorted signal. This algorithm has been validated for axial peaks within the range of 15.0–15.9 g. However, the accuracy of peaks of higher magnitude and the resultant peaks have not been reported. The purpose of the present study is to evaluate the measurement agreement of the restored peaks using a low-range accelerometer (±16 g) against peaks sampled using a high-range accelerometer (±200 g). The measurement agreement of both the axial and resultant peaks were examined. In total, 24 runners were equipped with 2 tri-axial accelerometers at their tibia and completed an outdoor running assessment. The accelerometer with an operating range of ±200 g was used as reference. The results of this study showed an average difference of −1.40 ± 4.52 g and −1.23 ± 5.48 g for axial and resultant peaks. Based on our findings, the restoration algorithm could skew data and potentially lead to incorrect conclusions if used without caution.
Quantification of Humidity and Salt Detection in Historical Building Materials via Broadband Radar Measurement
Authors: Blaschke Oliver , Brand Felix , Drese Klaus Stefan
Published: May 2023

For the investigation of moisture and salt content in historic masonry, destructive drilling samples followed by a gravimetric investigation is still the preferred method. In order to prevent the destructive intrusion into the building substance and to enable a large-area measurement, a nondestructive and easy-to-use measuring principle is needed. Previous systems for moisture measurement usually fail due to a strong dependence on contained salts. In this work, a ground penetrating radar (GPR) system was used to determine the frequency-dependent complex permittivity in the range between 1 and 3 GHz on salt-loaded samples of historical building materials. By choosing this frequency range, it was possible to determine the moisture in the samples independently of the salt content. In addition, it was possible to make a quantitative statement about the salt level. The applied method demonstrates that with ground penetrating radar measurements in the frequency range selected here, a salt-independent moisture determination can be carried out.

A economia imaginada do capitalismo agrário : questão agrária e modernização no Brasil
Authors: Maia Felipe
Published: May 2023

O livro trata de como as interpretações da questão agrária relacionaram-se com as transformações no mundo rural entre as décadas de 1960 e 1990 no Brasil. Mostra as diferentes alternativas em disputa no período e as estratégias de reforma da estrutura agrária e/ou de modernização da economia rural. Apresenta as consequências da hegemonia de uma política voltada para a adaptação das grandes propriedades rurais à economia industrial, que está nas origens do que seria posteriormente chamado de agronegócio. Longe de tomar essa formação como uma realidade autoevidente, mostra-se o trabalho de uma imaginação intelectual que agregou interesses e políticas para se tornar hegemônica e orientar um conjunto de ações sobre a terra e o trabalho no Brasil. Explica porque a modernização técnica da economia não foi capaz de produzir por si só transformações em outras esferas da vida social, em especial as relações de poder e de sociabilidade.
Transmasculinidades e educação : interfaces entre Rio de Janeiro e Minas Gerais : impasses entre a educação básica e o ensino superior
Authors: Franco Neil , Salvador Nayara Rios Cunha , Araújo Samuel Moreira de
Published: May 2023

Homens transexuais lutam pelo reconhecimento de suas identidades de gênero e passam a ocupar os mais variados espaços sociais, dentre eles as instituições escolares. A Educação Básica e o Ensino Superior foram palco desse processo através das narrativas de dez homens trans, sete fluminenses e três mineiros, que contam os embates enfrentados para fazer valer seu direito à cidadania. O uso do nome social e a utilização do banheiro foram os maiores obstáculos encontrados pelos sujeitos. Com menor incidência, mas não menos importante, a aula de Educação Física e as tensões vivenciadas com o corpo docente, discente e demais segmentos da comunidade escolar também foram vetores de exclusão. Essas experiências escolares nos instigam a compreender que “ser diferente faz a diferença” e coloca em cheque o discurso social tão divulgado de igualdade que ainda está distante de avançar as normativas legais e se configurar como uma prática real.

L’article relate ces observations et replace cette découverte dans le contexte régional.
Fermes d’État et développement rural
Authors: Jorge Cardoso Fernando
Published: May 2023

Le Mozambique, avec son expérience et son bilan controversé des fermes d’Etat, des coopératives rurales et des villages communaux, a relancé un débat classique en Afrique noire. L’opposition des premières aux deux seconds ne produit pas des politiques cohérentes. C’est plutôt de la mise en relation des fermes d’Etat (ou autres grandes entreprises rurales) avec l’économie paysanne environnante que peut venir une dynamique de développement. Cela implique d’en finir avec le caractère d’«enclave moderne» des entreprises publiques dans leurs régions et non nécessairement avec leur existence même.
Le colosse paralysé
Authors: Ollivier Claire
Published: May 2023

Cahora-Bassa, la plus grosse unité de production d’énergie hydro-électrique d’Afrique, n’a pas fonctionné plus d’un an d’affilée depuis sa mise en service en 1979. Ce colosse est en réalité structurellement conçu pour fonctionner avec l’Afrique du Sud, ce qui permet paradoxalement à cette dernière de s’en servir, par le biais des attentats de la RENAMO, comme arme de guerre économique contre le Mozambique et de pression sur le Portugal et l’Europe.
Conservation et développement local au Niokolo Koba
Authors: Takforyan Ani
Published: May 2023

La création d’aires protégées ne résoud pas le problème du renouvellement des ressources naturelles. De nouvelles politiques associant conservation et développement local sont nécessaires. La solution à long terme des situations conflictuelles impose un élargissement temporel et spatial de l’analyse. Le cas du Niokolo Koba illustre cet impératif d’analyse historique et économique, mettant en évidence l’importance de la propriété dans la réflexion sur le renouvellement des ressources naturelles.
Origine et évolution des partis et groupes politiques
Authors: Marchesin Philippe
Published: May 2023

Origins and evolution of parties and political groups.

Since it opened to modem political life, Mauritania has been characterized by the complexity of its ethnic and tribal referents. The evolution of the State and political parties, as well as nationalist projects are proof of the pregnancy of these parameters. The attempt to establish a modem state under Moktar ould Daddah went against the recrudescence, under military powers, of vertical logics engendered by these referents. The democratic opening has not perceptibly modified the deep-rooted balances of political life in Mauritania.
Les langues comme enjeux identitaires
Authors: Taine-Cheikh Catherine
Published: May 2023

Languages as identity.

If litterary Arab is, in Mauritania, the language of Islam and consequently the religious language of all, it however never meant that in the past all Mauritanians mastered it. During colonial times, a young francophone elite emerged and provided the state with part of its managerial staff. On the whole, however, the Maure majority, whose native language is an Arab dialect, has never stopped to ask for the predominance of Arab on French. As a consequence, the more of less conflictual relations between the Maures and the Negro-Africans those last thirty years have been somehow connected to the relations between French and Arab.
Sentiers inédits et voies fragiles au Burkina Faso : du commerce à l’industrie ?
Authors: Ganne Bernard , Ouedraogo Moussa
Published: May 2023

Le passage du commerce à l’industrie ne va pas de soi. A partir d’une monographie d’entrepreneur burkinabè ayant fait le saut, on constate à quel point le contexte social et politique peut favoriser l’investissement productif. Les réflexes «marchands» devant des difficultés de la gestion industrielle, la concurrence de biens du marché mondial et le manque d’agressivité des politiques commerciales rendent ces expériences encore aléatoires.
L’entrepreneuriat congolais à l’épreuve des pouvoirs magiques : une face cachée de la gestion culturelle du risque ?

Published: May 2023

Elle intervient aussi bien comme principe régulateur des successions, des changements de forme juridiques d’entreprises, de leur organisation interne.

La longue marche de l’UNITA jusqu'à Luanda
Authors: de Loanda Guilherme
Published: May 2023

UNITA long march to Luanda.

The national UNITA of pre-independence yielded to the power tightening of one man, Savimbi, not tolerating any disagreement, and to the ethnicization of actual power to the Ovimbudus’ benefit. This ethnic tightening was accompanied by a large intra-ethnic confusion. Confronted to the crisis of its administation, Savimbi had to reajust his position to keep on arbitrating between the various sensibilities.
