Extensive use of such fungicides leads to Cu diffusion in most soils and increases risk phytotoxicity for the tropical gum tree (Sterculia setigera) grown these soils. A pot experiment was set examine effect Arbuscular Mycorrhizal Fungus (AMF), Rhizophagus fasciculatus, soil copper levels content on mineral status Sterculia setigera. Plants were with different (0, 200, 400, 600 800 mg.kg-1 ). Control plants (C) found have survival rate 40% at Cu. Inoculated (T) their part had a 100%...
Abstract A chemometric methodology was used to study column efficiency and the separation of 10 benzodiazepines in reversed phase liquid chromatography. New simple mathematical models organic modifier (OM) organization ACN water, explained differences on observed when is chosen instead CH3OH. new response function, which takes into account quality analysis time, proposed for optimization. The result, a mobile ACN/water (60/40)(V/V), with flow rate = 1.00 mL/min temperature 47°C were optimum...

The production of seedlings for transplanting is one the most important stage to successful lettuce cultivation.Among techniques practiced obtain vegetables, stands out using agricultural substrates associated with cultivation trays.The experimental setup design was carried in completely randomized 5 treatments and 6 repetitions.The experiment a greenhouse, where were evaluated five commercial (TropstratoHT®, Vivatto Slim Plus®, Tecnomax® , Holambra HS® Bianchi Power) development cv.Lucy...
Au Maroc, pays du pourtour méditerranéen, les ressources en eau sont limitées et inégalement réparties dans l’espace le temps. Agadir, ville sud fait partie de la région Souss connue pour ses activités d’agriculture pêche. La est par un climat semi-aride grand déficit hydrique. Afin préserver qualité des masses d’eau diminuer prélèvements milieu naturel, il convient chercher approvisionnements alternatifs. réutilisation eaux usées épurées semble être une bonne alternative, notamment...
The hypothesis of a theoretical “slicing” the column in temperature-programmed gas chromatography for accurate forecasting retention time is tested by actually column. Calculated and observed times relation to length are good agreement.
Les eaux usées traitées par la station d’épuration (STEP) M’Zar du grand Agadir-Maroc peuvent être utilisées pour l’irrigation (catégorie A normes OMS). Le volume actuel est de 10000 m3/j et atteindra prochainement 50000 m3/j. Cette production d’eaux épurées (EUE) permettra combler entièrement les besoins en d’irrigation des espaces verts Agadir.Cette étude concerne faisabilité réutilisation EUE STEP gazons golfs. Elle présente planification, le protocole résultats essais qui ont été menés...
In gas chromatography, Golay’s equation shows that column efficiency, expressed as the height equivalent to a theoretical plate (HETP), strongly depends on linear velocity of carrier and oven temperature. The influence temperature is complex, it acts through diffusion coefficients compound behavior. A new directly relating HETP proposed. It based combination long-established empirical de Wet Pretorius modified form Golay equation. This tested with two different columns. fit model...
A pot experiment was set to examine the effects of arbuscular mycorrhizal fungi (AMF) on mineral nutrition a tropical legume tree (Acacia senegal) under three different water status. Acacia senegal seedlings were inoculated with species AMF, Glomus intraradices, Glomus fasciculatum or Glomus mosseae. Three levels (field capacity, moderate deficiency and severe deficiency) were applied pots after transplantation. A. colonized by AM fungi. Twelve...
The statistical technique of optimizing mobile phases for liquid column chromatography using overlapping resolution maps is transformed into a nonstatistical multifactor method. optimized parameters are the binary solvent composition, phase flow rate, and analysis time. main goal to obtain fastest compatible with desired separation. principle tested two different sets compounds in reversed-phase high-performance chromatography: mixture seven herbicides nine benzodiazepines.
