Investigations were carried out on spatial and seasonal composition, distribution and abundance of phytoplankton in Adjin lagoon located in south-eastern of Côte d’Ivoire. samples were collected at six stations during the four seasons in 2013 year. Freshwater inflow from Bété, Djibi and Mé Rivers influenced the variability of nutrients concentration in this lagoon. From a seasonal point of view, the parameters studied are significantly affected by freshwater inputs during the rainy season. This period is characterized by high values of turbidity, suspended solids and nutrients in the water. Overall, 66 taxa from six phyla were recorded. The Chlorophyta had the highest species diversity and Cyanobacteria had the highest relative abundance throughout the year. The temporal distribution of phytoplankton showed that the highest values of density were recorded in the long rainy season and the lowest values in the long dry season. spatially, the highest abundance (297,927 × 10sup>3sup> cells·Lsup>-1sup>) of phytoplankton was found in station 3 and the lowest (74,222 × 10sup>3sup> cells·Lsup>-1sup>) in the station 5.

Pelvic ultrasound is the first-line examination for the diagnosis of ovarian cysts. When coupled with Doppler, it allows the diagnosis to be directed towards the benign or malignant nature of the cyst. These benign tumors are frequent in pubertal period. We report a descriptive study in 35 patients aged between 18 and 32 years of age who received a pelvic inflammatory etiology assessment. The purpose of this study was to show the place of pelvic ultrasound in the diagnosis of ovarian cysts.

The objective of this work was to determine the suitability of poultry methacompost from the 2nd methanizer of the BRIN FOUNDATION in Yaokokoroko (Bondoukou, Côte d’Ivoire), to be used in the improvement of soil fertility. The methacompost studied has a C/N ratio = 17.26, which could characterize a stable methacompost with high amending power. It also contains mineral elements Nitrogen (N) = 0.68% DM;Phosphorus (P) = 0.084% DM;Potassium (K) = 0.67% DM;Calcium (Ca) = 0.65% DM;Magnesium (Mg) = 0.15% DM. red in the standard relating to the organic amendments (NFU 44-051). The methacompost has fertilizing and amending properties and could not present any risk for vegetation and soils.
