This study reports two observations of heart failure diagnosed in the context of SARS-CoV 2 infection in children at the University Hospital Center of Libreville, Gabon. Long considered exempted from serious forms of Covid-19 infection, the fatal evolution of one of the two cases proves that there is an interest for a more rigorous approach in their management in a pandemic context. The multisystem inflammatory syndrome associated with this virus in children can be responsible for cardiac manifestations that can be life-threatening. Early diagnosis and treatment are necessary to reduce mortality. However, this approach is made difficult in our regions by the limited biomedical equipment and the absence of essential therapies as noted in these two observations.

Many mobile robotics applications, especially in industrial environments, require the robot to perform safe navigation and then reach the goal with a high precision. In this research work, the objective is to analyze the appropriateness of autonomous natural navigation strategies for mobile manipulation tasks. The system must position itself in a realistic map, follow a path closely and then achieve an accurate positioning in the destination point in order to be able to perform the manipulation, inspection or pick task efficiently. Autonomous navigation is not able to fulfill the accuracy required by some of the jobs so that a second positioning system using vision is proposed in this paper. The experiments show that localization systems have, on average, an error greater than a decimetre and how an additional positioning system can reduce it to a few millimetres.

The authors encountered a case involving difficult intubation during anesthesia for revision of cervical fixation angle in a 62-year-old woman, with a history of chronic rheumatoid arthritis, who experienced dysphagia after initial posterior occipitocervical fusion to correct atlantoaxial subluxation. Two days after initial surgery, she developed trismus with neck flexion and dysphagia, and underwent revision surgery. General anesthesia was planned;however, tracheal intubation using the McGrath laryngoscope and bronchofiberscope was difficult, which prolonged anesthesia induction. Narrowing of the oral and pharyngeal cavities associated with overcorrection of the cervical spine was believed to be the reason for difficulty in manipulating the tracheal intubation devices. In posterior occipitocervical fusion, intraoperative evaluation of the occipito-second cervical vertebra (o-C2) angle is reported to be useful in preventing postoperative dyspnea and/or dysphagia, and avoids the need for revision of fixation angle. However, when revision surgery is needed, selection of airway management methods and tracheal intubation devices are important considerations because patients are likely to have restricted mobility in the cervical spine and narrowing of the oral and pharyngeal cavities.

The evaluation of the new cultivars adaptation and yield potential of Mangifera indica L. provides tools to assist and improve the mango production in different climates conditions. This study aimed to evaluate the phenological and reproductive development of five mango cultivars (Bourbon, Haden, Palmer, Parwin and Tommy Atkins), on climate conditions in dry land and four production cycles (from 08/2007 to 01/2011), at S?o Manuel, S?o Paulo state, Brazil. The variables were total plant height, trunk height, stem diameter and the first insertion diameter, fruits physical characteristics, yield and harvest period, flowering seasonality and morphological characterization of the inflorescences. It was found that the four-year-old plants of Haden cv. reach 4.0 m high and 0.20 m of trunk diameter. Bourbon cultivar had the highest flowering period, from April to october. Tommy Atkins cv. had productivities of 14779.07 kg·ha-1 in the fourth cycle and the productivity of Bourbon, Haden and Palmer cultivars was alternated.

通过吡啶酰胺类配体3,5-二(4-吡啶酰胺基)吡啶(4-DPBA)与相应金属盐反应,合成了3个配位聚合物{[Zn(4-DPBA)2(No3)2].4DMF}n(1),{[Cd(4-DPBA)2(No3)2].4DMF}n(2)和{[Cu(4-DPBA)2(DMF)2](Clo4)2.7DMF.2H2o}n(3),并用红外光谱、元素分析、粉末及单晶X-射线衍射等方法对其进行了表征。结果表明配合物1和2是同构的,由平行的一维带状链通过氢键连接而成二维层状结构,而配合物3是由3种不同取向的一维带状链构成二维多层结构。这3个配合物最终均通过氢键连接形成三维超分子结构。研究了配合物1和2的荧光性质。
