Production of this crop is experiencing significant challenges, resulting in a decline in seed and fiber quality. To address this challenge, generations of high-performance cotton plants of the Gossypium hirsutum L. species have been developed and are currently being commercialized. This study evaluated the impact of gin types on the agro-industrial quality of cotton in Côte d’Ivoire. To this end, cotton from the G3, R1, and R2 generations was harvested, sampled, and ginned on machines with 10 and 170 saws in the localities of Ouangolodougou, Ferkessédougou, Korhogo, M’Bengué, Boundiali, Séguéla, and Mankono, as well as at the Centre national de Recherche Agronomique CnRA) in Bouaké. The results demonstrated that cotton fibers obtained from ginning on 10-saw machines exhibited superior quality compared to those from 170-saw machines. Fiber length, fiber length uniformity, and short fiber rate exhibited the highest deviations according to gin type. The use of 170-saw gins resulted in a notable decline in quality. Conversely, micronaire index, fiber tenacity and elongation, and reflectance remained consistent across machine types. These results will enable us to more effectively regulate and advise cotton-processing factories, which primarily utilize 170-saw gins to enhance agro-industrial quality in Côte d’Ivoire. Furthermore, these results will assist breeders in incorporating them into their processes to enhance the quality of the varieties they offer to farmers.

The Japanese quail (Coturnix japonica) is a disease-resistant, high-productivity bird. It has few breeding constraints. A phenotypic characterization study of the Japanese quail was carried out in southern Côte d’Ivoire to gain a better understanding of this bird. The study involved 298 individuals. The phenotypes were white, black, gray, and red. A total of 11 morphometric parameters were examined. Variables were significantly different between the phenotype and sex groups. The female quail was larger than the male quail. The quail was 20.77 and 4.10 cm long. The head was supported by a 5.89 cm-long neck. The tail was 3.61 cm long. The wing length was 10.42 cm, and the thigh diameter was 2.12 cm. The tarsus was 3.39 cm long and 0.61 cm in diameter. The average quail weight was 297.06 g. The quails in this study exhibit a high degree of morphological variation between individuals in terms of plumage. These results can help develop strategies for developing and genetically improving this short-cycle resource.

The aim of this study is to describe the manifestations of abuse of women in childbirth. The techniques and tools for collecting data are documentary research, observation, questionnaire and interview. The study was based on a sample of 72 people determined according to the method of reasoned choice. As for data analysis, the method of processing is qualitative and quantitative. In terms of results, it should be noted that the average age of women in childbirth is 23 and those aged 16 - 24 represent the largest segment of the survey population. Most of these women are illiterate or drop out very early. They belong to several religious communities and are of various nationalities. Regarding the manifestations of mistreatment, we retain that they are of several types the most significant of which are verbal abuse, physical abuse, neglect and psychological abuse. These abuses have taken place for some women at their first or last delivery, at all their deliveries or at a single delivery. In general, young women between the ages of 16 and 25 are the most victims of mistreatment in childbirth. Various authors are at the origin of the mistreatment of women in childbirth. They are young midwives often single and childless.

Introduction: The curative management of primary hyperparathyroidism is based on surgery. We report the case of a patient presenting with elevated parathormone despite surgical removal of the parathyroid adenoma. Observation: A 48-year-old patient presented for more than 6 months with significant weight loss, polyuria with polydipsia and impaired renal function. The assessment carried out revealed hypercalcaemia at 155 mg/L with hypophastetaemia at 24 mg/L and an elevation of the parathyroid hormone at 218.9 pg/ml. Cervical ultrasound showed a mass at the expense of the lower left parathyroid gland. These results made it possible to conclude primary hyperparathyroidism by parathyroid adenoma which was supported surgically. The postoperative biological assessment revealed a normocalcemia at 85 mg/L associated with an increase in parathormone (PTH) at 271.9 pg/ml. In front of the normalization of calcemia in the subsequent controls and the amendment of all the signs, monitoring was carried out. 9 months after surgery, spontaneous normalization of PTH was observed at 38.4 pg/ml with normal serum calcium at 90 mg/l. Discussion: Primary hyperparathyroidism can be revealed by other manifestations. Post-operative follow-up is generally simple with normalization of PTH and serum calcium. However, there may persist an elevation of PTH with normal self-limiting calcemia.

Okra is a plant rich in nutrients and is very well consumed in Côte d’Ivoire. Despite its many benefits, the production of this vegetable is still weak in our country. The reasons for this include the inadequate selection of varieties, the high cost of inputs and the poverty of the soil for its cultivation. One of the alternatives for sustained production is to solve the problem of soil fertility. In the case of our work, the aim is to improve the yield of okra. To achieve this goal, experiments were undertaken to evaluate the impact of activated charcoal on morphological parameters of a local okra variety. For this purpose, the charcoal used was activated in three different times (activation time equal to 0 days, 15 days and 30 days). The experimental device used is a split-plot with three repetitions, each comprising 12 elementary plots. The various charcoals were buried the same day. Then, the seedling was done with two positions including outside position and inside position. Observations were made on 360 plants. An analysis of the variances was carried out on the morphological parameters. Fruit mass is the variable most influenced by activated charcoal. Thus, the greatest value of the mass was obtained with the charcoal CA0, with outside position.
