ABSTRACT
Yield is one of the most important component in breeding program and it depends on the relationship between plant traits. Twenty (20) hybrids of tropical maize were evaluated to investigate the relation between various traits and yield at the research and development farm of the faculty of Agriculture, Nasarawa State University Keffi, Nigeria. Two environment were used for this experiment which include 2021 for non-stress and 2022 for stressed and the experiment was laid out in a complete randomized block design with three replications. The result showed significant difference among the studied traits exception for Days to anthesis, Days to maturity, Protein content and Days maturity for stress and non-stressed respectively. Correlation analysis suggest that there is a perfect relationship between Days to silking and Days to anthesis (0.98) for non-stress and a moderate relationship (0.55) under stressed environment while there is a moderate negative correlation between Days to silking and Protein content (0.52) for stress condition.

ABSTRACT
This work's main objective was to evaluate the effect of certain strains of arbuscular mycorrhizal fungi on acid phosphatase activity during growth. The treatments applied were, control, Glomus intraradices, Acaulospora tuberculata, Gigaspora margarita, Glomus sp., and the mixture of these four AMF strains. Their effect on the growth of vitroplants was evaluated on days 60, 120, and 180 after inoculation. Mycorrhizal status following treatments and acid phosphatase activity were assessed. The minitubers obtained were subjected to a preservation and germination test. The results showed that the maximum growth peak of X. sagittifolium plants was obtained on day 120 for all treatments. The mixture of the four strains of AMF had more influence on the growth parameters with values of 18.40±0.54 Cm and 42.34±16.67 Cm2, respectively for the average number of roots and leaf area. Mycorrhization did not significantly influence the mean number of leaves and mean plant height. Mycorrhizal structures were observed in all mycorrhizal treatments applied. The frequency of mycorrhization was very high in plants inoculated with Glomus sp. The evaluation of the phosphatase activity shows a significant activity at the level of the leaves with a peak of activity in the plants inoculated with Glomus sp. (47.72±0.07 µM/min/g of FW). Compared to the control, the number of minitubers produced was two to three times higher. The best tuberization percentage (80%) was obtained in plants inoculated with a mixture of AMF strains. The temperature of 7~10°C allowed the preservation of 50% of the germination capacity of the minitubers after two months. Based on the obtained results, it was concluded that fertilization with AMF is beneficial for the stimulation of minitubers production.

ABSTRACT
Neurofibromatosis type I (NF1) or Von Recklinghausen disease is one of the most frequent genetic diseases with polyvascular manifestations, including the eye. Its prevalence was variously estimated varying between 1/7800 and 1/2000. The diagnosis of NF1 is essentially clinical based on criteria established by the consensus conference of the National Institute of Health (NIH) in 1988. Several complications have been reported by numerous authors in cases of plexiform neurofibromas sometimes associated with congenital glaucoma. We report two cases of monocular blindness, complications of this disease in children, responsible for stigmatization by their peers and school dropout, seen at the National Hospital of Zinder, Niger.

ABSTRACT
Background: The aim of this study was to evaluate the practice of pediatric anesthesia in an adult operating theater in sub-Saharan Africa. Patients and Methods: This was an observational, prospective descriptive study that took place over a period of 12 months in the anesthesiology department of the Essos hospital center in Yaounde (Cameroon). Children <15 years old, seen in anesthesia consultation and operated on for scheduled surgery during the above- mentioned period were included in the study. The variables studied were the variables studied were: the characteristics of the study population, the anesthetic and surgical data, as well as the patient's postoperative itinerary. Results: During the study period, 162 patients were included out of a total of 1205 patients operated on during the same period. The median age was 5 years, the sex ratio 1.8. ASA class 1 was the most represented (98.1%). The combination midazolam and atropine was the premedication of choice (87.1%). General anesthesia was the most practiced technique (96.3%). Induction of general anesthesia was inhalation in 69% of cases, sevoflurane was the hypnotic used in this indication. General anesthesia was performed by a senior anesthesiologist in 67.3% of children. The majority of surgical procedures belonged to otolaryngology surgery (57%). The electrocardiogram (ECG), blood pressure, SpO2 and heart rate constituted the main part of the intraoperative monitoring. Conclusion: In low-income countries, pediatric anesthesia is still performed by personnel who are not specialized in pediatric anesthesia. In order to improve the safety of children in the operating room, health policies must encourage training and specialization in this highly delicate area, which will make it possible to reduce perioperative infant morbidity and mortality.

ABSTRACT
In 2008, Indonesia witnessed a global financial crisis. Due to variations in the rupiah currency rate, importers encountered financial difficulties, which was one of the effects. On September 3, 2019, the exchange rate between the rupiah and the U.S. dollar fell to 14,230 per dollar. This Study's Objective Is To Evaluate The Impact of Cash Flow, Profit, And Corporate Governance On Financial Disaster Conditions (Study on Manufacturing Companies Listed on the Indonesia Stock Exchange in 2015-2018). Secondary data from the 2015-2018 annual reports of manufacturing enterprises collected from www.idx.co.id were used for this study. There are 135 manufacturing enterprises in all. There are 22 manufacturing enterprises in the sample. The findings revealed that the Cash Flow Variable had no impact on financial distress. Variable profit has a detrimental impact on financial distress. The Board of Directors variable does not affect financial distress. The Board of Commissioners variable does not affect financial distress. The variable Institutional Ownership hurts financial distress. The contribution of research to the firm's Board of Directors is a consideration of the company's financial status in order for the company to have good financial reports and prevent financial difficulty. Investors and creditors must pay close attention to the company's. Financial condition and be selective and cautious about the company's actual condition.
