Abstract:
Résumé L’étude des caractéristiques physico-chimiques des eaux souterraines de la communauté Mzamza, soumises aux rejets liquides de la ville de Settat à partir de l’oued Boummoussa, montre que la qualité des eaux des différents puits est variable et dépend d’un certain nombre de facteurs tels que l’emplacement des puits par rapport aux eaux usées et l’activité agricole. L’interprétation des données d’analyse, la corrélation existante entre eaux usées et eaux de puits, et la répartition des eaux souterraines en groupes sont réalisées en utilisant l’Analyse en Composante Principale Normée. L’étude a révélé des origines différentes de la contamination des eaux souterraines, à savoir, la contamination par la matière organique due essentiellement à l’utilisation des eaux usées à des fins d’irrigation et à leur infiltration continue, et finalement le retour des eaux d’irrigation (chargées en engrais azotés) qui est considéré comme étant la principale origine de la minéralisation et de la pollution des eaux. Plusieurs facteurs conditionnent la progression de cette pollution : les concentrations des polluants dans les eaux usées, la nature des sols, la lithologie, la perméabilité de l’aquifère exploité et la profondeur de la nappe. Les résultats acquis dans cette étude font ressortir également l’influence primordiale des variations saisonnières, ainsi que le rôle bénéfique des précipitations.

1 RESUME Une étude sur la fertilisation minérale et organique liquide a été conduite sur la tomate en petite saison de pluie au Sud et au Centre-Ouest de la Côte d’Ivoire sur deux années, afin d’améliorer la fertilité du sol et le rendement de la tomate. De manière spécifique, il s’agissait d’évaluer les effets des traitements de quatre doses d’engrais organique liquide associées ou non à l’engrais minéral sur la teneur du sol en matière organique, le rapport C/N et le rendement. Le dispositif expérimental était un split-plot avec quatre répétitions ayant pour facteur principal, l’engrais minéral et le facteur secondaire, l’engrais organique à quatre doses (Lha-1) : C0 = 0 (témoin), C1 = 2,5; C2 = 3,75 et C3 = 5. Les résultats ont montré que le traitement T10 (50 % engrais minéral + 3,75 Lha-1 engrais organique) a amélioré la teneur du sol en matière organique, et le rendement. Cependant, le traitement avec 3,75 Lha-1 d’engrais organique utilisée seule a amélioré le rapport C/N du sol. Effects of liquid organic (NPK 5-9-18) and mineral (NPK 12-11-18) fertilizers on soil organic matter of and tomato yield in the South and the Mid-west of Ivory Coast ABSTRACT A study on the mineral and liquid organics fertilizations was conducted on tomato during short rainy season in South and Central West regions of Ivory Coast over two years to improve soil fertility and tomato yield. Specifically, the treatment effects of four doses of organic fertilizer, associated or not with the mineral fertilizer on the content of the soil organic matter, the C/N ratio and the yield. The experimental design was split-plot, with four repetitions having as principal factor, the mineral fertilizer and the secondary factor, the organic fertilizer in four doses (L ha-1): C0 = 0 (control); C1 = 2.5; C2 = 3.75 and C3 = 5. The results showed that the treatment T10 (50 % mineral fertilizer + 3.75 Lha-1 of the organic fertilizer), better improved the content of the soil organic matter and the yield. However, the treatment with 3.75 L ha-1 of organic fertilizer used alone has increased advantage the report C/N of the ground.

Abstract:
ResumoO texto circunstancia o recorte de uma fundamentação teórico-prática na qual a palavra-imagem múltiplo é instaurada como um dos argumentos poéticos empregado nas obras autorais da artista-pesquisadora Marcillene Ladeira. Como metodologia, utiliza-se o mergulho histórico, tendo, neste transcurso, a gravura como ponto de partida – pois a esta linguagem, conforme consenso à falta de pesquisadores, originalmente reserva tal conceituação –, bem como a investidura sobre estratégias contemporâneas de criação, enfatizando, especialmente, a imagem figurativa, artistas e obras. Sustenta-se que o múltiplo – entendido enquanto possibilidade de reprodução “numa espécie de linha de montagem” – permitiu estabelecer diálogos profícuos de pensamento. Em uma leitura de aproximação com a Pop, mas em envergadura diferenciada, as obras em discurso transitam do imaginário do consumo para o pós-consumo, cuja poética se sustenta por três conceitos operacionais: “liquidez”, “respeito a natureza” e “transitoriedade” enquanto seres viventes. As relações dialógicas estabelecidas no lugar da exposição também são evidenciadas como estratégia pessoal de produção e singularidade deste fazer, sobre a égide da interfase: múltiplo-lugar-poética.AbstractThe text provides a clip of a theoretical-practical foundation in which the multiple word-image has established as one of the poetic arguments used in the authorial works of the artist-researcher Marcillene Ladeira. By methodology, the historical diving is used, to take this course, the engrave as a starting point – because this language, according to a consensus with abundance of researchers, originally reserves this concept –, as well as the investiture on contemporary strategies of creation, emphasizing especially the figurative image, artists and works. It has maintained the multiple - understood as the possibility of reproduction "in an assembly line type" - allowed establishing a fruitful dialogue of thinking. In a reading of rapprochement with Pop, but in a different wingspan, the discourse works move from the imaginary of consumption to post-consumption, whose poetics is supported by three key operational concepts: “liquidity”, “respect for nature” and “transience” as living beings. The dialogical relations established in the place of the exhibition are also evidenced like a personal production strategy and singularity of this doing, under the aegis of the interphase: multiple-place-poetics.
