Abstract:

The article attempts to show that the 2011 social movement in Tunisia was part of a process that began a few years earlier. At that time the essentially socio-economic protest movement was confined to the mining town of Gafsa. The multiplication of such movements, although sporadic, would continue to fuel the mobilization until 2011 and was characterized by the emergence of a wave of protests that were essentially socio-economic in the early days, though it was not long before they presented a challenge to the political order, in particular as they spread to the rest of the country.

Abstract:

Cette étude a cherché à déterminer la dynamique des populations de tiques infestant les ovins dans la région de Gafsa (centre de la Tunisie). Les tiques ont été prélevées sur 57‒64 moutons de race Barbarine choisis au hasard chaque mois pendant un an, d’octobre 2013 à septembre 2014. Au total, 560 tiques ont été collectées et identifiées. Elles appartenaient à deux espèces : Rhipicephalus sanguineus sensu lato (98,6 %) et Hyalomma excavatum (1,4 %). Les ovins n’ont été infestés que d’avril à octobre avec une prévalence maximale (nombre d’animaux infestés / nombre d’animaux examinés) en août pour R. sanguineus s.l. (83 %) et en mai pour H. excavatum (7 %). L’intensité d’infestation maximale (nombre de tiques / nombre d’animaux infestés) a été de 3,7 tiques par animal en août. Ces données seront très utiles pour les éleveurs d’ovins et les vétérinaires pour mettre en place des mesures de lutte efficaces contre les tiques et les pathogènes qu’elles transmettent.

Abstract:

La ville de Métlaoui constitue le noyau urbain central du bassin minier de Gafsa (BMG) au sud-ouest de la Tunisie. À l’instar des autres villes du bassin, Métlaoui est traditionnellement caractérisée par la mono-activité industrielle d’enrichissement de phosphate ; elle observe par ailleurs une dichotomie spatiale entre « le village européen » relativement favorisé qui constitue le cœur de la ville et les cités périphériques ouvrières très déshéritées. Cette dichotomie ne semble pas faiblir aujourd’hui ; bien au contraire, la recherche montre aujourd’hui les prémices d’une accentuation des ségrégations socio-spatiales héritées de la période coloniale et postcoloniale, les vicissitudes environnementales accumulées confirmant ces prédispositions d’iniquité territoriale. La méthodologie de travail a utilisé, côté socio-spatial une documentation hétérogène et open source : photos aériennes et images Landsat multidates (1952, 1976, 1991 et 2019) et du PAU (1978, 1992 et 2008) et recensements, analyses diachroniques de l’occupation du sol, durant les dernières décades. Côté environnemental, nous avons procédé à des analyses chimiques effectuées sur la composition du sol urbain des différentes entités spatiales de Métlaoui choisies judicieusement, notamment en termes de contenance de métaux lourds et évaluation des risques encourus par ces entités en termes de distances aux principales sources de pollution et de gravité réelle selon les standards internationaux et leur distance par rapport aux différentes unités urbaines. Les objectifs de la recherche sont donc d’examiner l’occupation du sol urbain et son évolution récente par le biais d’un SIG-minier, d’une part ; d’étudier ensuite par le biais d’une analyse multicritères (AMC) utilisant la méthode « ordered weighted average » (OWA) certains aspects de la question environnementale, d’autre part. Le tout est intégré dans un SIG-AMC. Les résultats cartographiés à partir du SIG et de l’AMC fournissent un diagnostic territorialisé sur les inégalités territoriales et sur les risques sévères encourus par la ville. Les produits cartographiques peuvent aider les décideurs à prendre des solutions viables en termes de protection et remédier aux dangers encourus.

Abstract:

Purpose The purpose of this study is to show the specificities of the corporate governance of Tunisian financial institutions and the impact of the internal mechanisms of corporate governance of these institutions on their social performance. It is therefore interesting to establish the existing relationship between these mechanisms of corporate governance and the performance of a financial firm. Design/methodology/approach This study aims to study the financial sector, generally characterized by its opacity, its regulation, its evolution and its obscurity. Therefore, a study based on the questionnaire method was recommended. The questionnaire is intended for managers. Therefore, the authors interviewed 138 managers of Tunisian financial institutions dispersed between agencies and headquarters in different regions (Gabes, Tozeur, Gafsa, Sfax, Sousse and Tunisia). Findings As a result, an impact on performance was observed according to the empirical study. Therefore, the authors can conclude an essential role of internal mechanisms for improving the social performance of a financial institution. The empirical findings in this paper lead to important conclusions. Indeed, the variables measuring the governance mechanisms have divergent effects on the social performance of the financial institutions subject to the sample. For the variables board of directors, confidence, culture, auditing, they have a positive effect. While, the incentive remuneration effect negatively the social performance. Originality/value This study will be based essentially on the financial sector in Tunisia: the credit institutions (22 banks), the establishments of leasing (eight companies of leasing), two factoring companies and two banks of cases which are listed on the Stock Exchange of Tunis (BVMT).

Abstract:

Abstract. Some ground based measurements of solar radiation by using a sun photometer, have been conducted in Tunisia during the period of November 2000–February 2002. Five key measurement sites were selected: Three Sites (Tunis, Sousse, Gabes) are located on the Mediterranean coast and Two sites (Gafsa, Tozeur) on the boarder of Sahara. Over a total of 149 measurement days, 21 days are identified as clear sky, 114 days as Cirrus clouds and 14 days as aerosols. Aerosols and Cirrus clouds Optical Thickness (AOT) are derived from photometric measurements at 532 nm wavelength. Spatial and temporal variabilities of AOT are presented and discussed in this paper. Cirrus clouds were frequently observed at Gafsa and Tozeur where saharan aerosol events are expected to be more frequent than cirrus clouds. The mediterranean sea and saharan aerosols are suspected to have the main role in cirrus clouds formation, by providing water vapor and high concentrations of cloud condensation and ice forming nuclei.

Abstract:

This article seeks to evidence the social, environmental and political repercussions of phosphate extraction and transformation on two peripheral Tunisian cities (Gabes and Gafsa). After positing the difference between class environmentalism and political ecology, it addresses the harmful effects of phosphate transformation on the world's last coastal oasis and on various cities of the Gulf of Gabes. It then sheds light on the gross social, environmental and health inequalities brought about by phosphate extraction in the mining region of Gafsa. The confiscatory practices of the phosphate industry are subsequently linked with global production and distribution chains at the international level as well as with centralized and authoritarian forms of government at the national and local level. Dispossessed local communities have few alternatives other than violent protest movements and emigration towards urban centers of wealth. Using the recent experience in self-government in the Jemna palm grove, the article ends with a reflection on the possible forms of subaltern resistance to transnational extractivism and highlights the ambiguous role of the new "democratic state" as a power structure reproducing patterns of domination and repression inherited from the colonial period and cemented under the dictatorship of Ben Ali.Keywords: political ecology, transnational extractivism, phosphate, Tunisia.

Abstract:

Faba bean (Vicia faba L.) is one of the most important legumes in the world. Little is known about the genetic resources of faba bean in Southern Tunisia. In the present study, genetic diversity within Tunisian faba bean germplasms was investigated using 16 simple sequence repeat markers. In total, 50 alleles were detected. The number of alleles per marker ranged from 2 to 6, with an average of 3. Genetic diversity and polymorphism information content values averaged, respectively, 0.43 (range 0.34–0.51) and 0.36 (range 0.28–0.43). The mean heterozygosity value was 0.27. A model-based structure analysis based on neighbour-joining tree and factorial correspondence analysis revealed the presence of two subpopulations, consistent with the clustering based on genetic distance (GD). The overall Fis value was 0.36, indicating the importance of selfing in these populations. Analysis of molecular variance revealed that the within-population genetic variance component was much higher than the between-population or between-subpopulation variance component. The genetic relationships based on Nei's GD revealed that AGD (Aguadulce) and SAG (Super Aguadulce) and TF1 and TF2 (Tafartassa-Gafsa) were the most closely related populations. Assessment of genetic variation within faba bean populations will be informative for the conservation of germplasms and the implementation of effective breeding programmes in Tunisia.

Abstract:

The raw phosphates in the Gafsa-Metlaoui phosphate basin are valorized by wet processes that are performed in the laundries of the Gafsa Phosphates Company (CPG, Gafsa, Tunisia) to reach market grades (>28% P2O5). This enrichment process allows the increase of P2O5 content by the elimination of the coarse (>2 mm) and fine (<71 µm) fractions. Mineralogical analysis has shown that all the investigated materials (raw phosphate, marketable phosphate, coarse waste, and fine waste) from the laundries of M’Dhilla-Zone L and Redeyef are both composed of carbonate fluorapatite, carbonates, quartz, gypsum, clays, and clinoptilolite. Chemical analysis shows that Cr, Cd, Zn, Pb, and U are concentrated in the fine wastes and associated with the clay–phosphate fraction. The rare earth elements are more concentrated in both raw and marketable phosphates. Drilling and sludge-water analysis, along with leaching tests conducted on the fine wastes, showed that, due to phosphate industry, cadmium, fluorine, and sulfate contributing to the pollution of water resources in the region, pollution is more conspicuous at M’Dhilla.

Abstract:

AbstractThree raw samples of Fe-rich smectites from Gafsa (Jebels Shemsi and Hammadi, Tunisia) have been characterized by different techniques which indicate that they contain (15 – 20%) illite, probably interstratified and to a lesser extent they also contain kaolinite, calcite, quartz and Fe oxides. These samples present a relatively high Fe content (∼9%) in the <2 μm fraction. From EPR and Mössbauer spectroscopy it is deduced that Fe is mainly present as Fe(III) in the octahedral environment of smectites and also in Fe-oxyhydroxides associated with the clays. Aluminium-pillared clays have been prepared from the Na+-purified samples, and their thermal stability and acidity have been studied.

Abstract:

The aim of this study was to investigate the chemical composition of the best known plants biomarkers from the locality of Gafsa (Tunisia). Majority of investigated plants had high levels of phenolics and exhibited noteworthy antioxidant activity. The plants showing the highest antioxidant activities were P. angustifolia, T. garganica, G. alypum and L. multifida. P. angustifolia demonstrated by far the most potent antioxidant activity, as well as total phenolic and total flavonoids content. In flavonoid structure of the aerial parts of the related species, different amounts of rutin, myricetin, morin, quercetin and kaempferol together with ergosterol, stigma sterol and b-sitosterol as phytosterols, vitamin D, vitamin K, a-tocopherol and retinol as vitamins, and arabinose, fructose, glucose, sucrose and maltose as sugars were found. The mineral analysis was related to the existence of Ca, Na, K, Fe, Mn, Zn and Mg with different amounts in all of the nine tested species.

Abstract:

Abstract The objective of this study was to investigate the ability of cactus Opuntia ficus-indica, used as a natural flocculant in the treatment of phosphate clay as an industrial wastewater. It is a new process that has proven very promising in the removal of high turbidity from industrial effluents. The volume of clear water recovered (supernatant) is one of the characteristic features which allow us to judge the effectiveness of this bioflocculant. The following of the settling velocity on the one hand and the analysis of supernatant and sludge on the other hand allow us to compare the cactus-based flocculant effectiveness with that of a chemical flocculant (CF) of anionic polyacrylamide nature. The optimum pH required for maximum settling velocity was found to be 12. Obtained results indicated that after 900 seconds of settling, the highest volume of clear supernatant was obtained with the natural flocculant (740 mL/L), against 666 mL/L obtained with CF. Several analyses on recovered clear water (pH, turbidity, Cu, Zn, Fe, Cd and Cr) and on dry sludge (P2O5, CaO, MgO, organic C, SiO2 and Cd) are highlighted.

Abstract:

An olive breeding program was started in Tunisia in 1993 in order mainly to improve the fatty acid composition of the local cultivar ‘Chemlali Sfax’. ‘Zeitoun Ennour’ is a new cultivar obtained from a cross between ‘Chemlali Sfax’ and the local dual-purpose use cultivar ‘Chemchali Gafsa’. The morphological study of this cultivar showed that eleven characters dealing with fruit and endocarp differed from ‘Chemlali Sfax’, mainly regarding to their respective weights. This new cultivar had the same sensitivity to Verticillium dahliae Kleb and earlier bearing than the original variety. Its olive production was considered as high as for ‘Chemlali Sfax’ but with partial self-compatibility and late maturity. The new cultivar realized a net improvement in comparison with the original cultivar particularly regarding its fatty acid composition with very high oleic acid content (>75 %) and low palmitic and linoleic acid contents (<10 %). The new cultivar was recently released and will be available for growers as soon as possible.

Abstract:

The Tunisian economic facts after the so-called the Arab spring or social revolution have been marketed by numerous fluctuations and radical changes in the general situation of the management of the administrative affairs of the country. The most prominent of these facts, including the series of chaotic sit-ins and the political and security instability that has increased from 2011 to 2018, note in particular the emergence of the phenomenon of terrorism and assassinations. These negative results are too the expensive cost of the Tunisian national economy, which has been directed, affected by all vital sectors of the country’s economy, especially the tourism, trade and investment sectors. In addition, the increase in excessive wages during the first three years following the revolution and the increasing number of random sit-ins that led to the cessation of the production in the Gafsa phosphate mine and the failure to work for most of the public servants represented negative factors that led to a decline in productivity and an increase in the financial and trade deficit. Thus, the budget deficit and the accumulation of indebtedness represent the main obstacle to achieving social and economic stability.
