Sylvie Ndongo Amougou, Dieudonné Danwe, Ba Hamadou, Bonaventure Jemea, Ahmadou Musa Jingi
Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104247
Background: There is paucity of data on congestive heart failure (CHF) in the intensive care unit in our setting. This study aimed to provide a better knowledge of pattern and outcome of CHF in the intensive care unit of the Yaounde University Teaching Hospital. Methods: We carried out a descriptive and retrospective study over a period of 21 months. We collected sociodemographic, clinical, paraclinical outcome and medication data from patients’ files. Statistical analysis was done using SPSS Version 20.0 Software. Results: We included 24 patients in this study. CHF represented 6.7% of admissions in the ICU. The sex ratio was 1. The mean age was 62 ± 16 years. The most frequent comorbidity was hypertension (50%). Most of the patients (84.6%) were classified Stage IV according to the NYHA. Dyspnea on exertion was the most frequent symptom (87%), while bilateral fine crackles were the main findings on physical exam (75%). Atrial fibrillation was the most frequent abnormality on ECG (53.3%), and most of the patients had a severe decrease in LVEF (87.5%). The mean duration of hospital stay was 10 days. In hospital, mortality was 25%, and this was significantly associated with mean blood pressure < 80 mmHg (p = 0.045). Conclusion: Clinical patterns of CHF in the ICU differed from those found in standard hospital care. Mean blood pressure was significantly associated with outcome. These characteristics should be taken in account while planning the treatment of these patients.

Introduction: The cold test is known as a predictor of essential hypertension. The hemodynamic response to this test has rarely been studied in black African adults. Black Africans also suffer cold stress. But whether they suffer it the same way as other populations is still to be determined. Equipment and Method: We studied the response of blood pressure (BP) during the cold test in 62 black normotensive adults and hypertensive Cameroonians aged between 21 and 59 years. Those with an increase in systolic blood pressure (SBP) > 20 mmHg and/or diastolic blood pressure > 15 mmHg were considered to be hyper-reactors. Results: SBP increased significantly in hyper-reactors compared with normo-reactors in both hypertensive and normotensive subjects (176 ± 20 vs. 154 ± 11, p = 0.01 and 148 ± 17 vs. 125 ± 11, p < 0.001, respectively) and this increment persisted up to two minutes after the end of the stress exposure although the difference was no more statistically significant. We found the same result for the DBP (111 ± 13 vs. 99 ± 10, p = 0.04 and 95 ± 11 vs. 81 ± 10, p = 0.001, respectively). However, the DBP stayed higher in hyper reactors compared to normal reactors in the normotensive group up to four minutes after cessation of the stress exposure. The recovery time of the baseline BP was considerably longer in hyper reactors compared with the normal reactors (2.1 ± 0.9 vs. 1.1 ± 0.4 minutes, p = 0.01 and 1.9 ± 1.0 vs. 1.3 ± 0.5 minutes, p = 0.03 respectively in hypertensive and normotensive). Conclusion: Hyper reactors in the cold test have a more pronounced and prolonged reactivity. They are thus predisposed to develop hypertension.
Deploying Safety-Critical Applications on Complex Avionics Hardware Architectures  [PDF]
Robert Hilbrich, Laurent Dieudonné
Journal of Software Engineering and Applications (JSEA) , 2013, DOI: 10.4236/jsea.2013.65028

Aviation electronics (avionics) are sophisticated and distributed systems aboard an airplane. The complexity of these systems is constantly growing as an increasing amount of functionalities is realized in software. Thanks to the performance increase, a hardware unit must no longer be dedicated to a single system function. Multicore processors for example facilitate this trend as they are offering an increased system performance in a small power envelope. In avionics, several system functions could now be integrated on a single hardware unit, if all safety requirements are still satisfied. This approach allows for further optimizations of the system architecture and substantial reductions of the space, weight and power (SWaP) footprint, and thus increases the transportation capacity. However, the complexity found in current safety-critical systems requires an automated software deployment process in order to tap this potential for further SWaP reductions. This article used a realistic flight control system as an example to present a new model-based methodology to automate the software deployment process. This methodology is based on the correctness-by-construction principle and is implemented as part of a systems engineering toolset. Furthermore, metrics and optimization criteria are presented which further help in the automatic assessment and refinement of a generated deployment. A discussion regarding a tighter integration of this approach in the entire avionics systems engineering workflow concludes this article.

Barthes, leitor de Malraux: uma oculta??o terrorista
Dieudonné, Julien;
Alea : Estudos Neolatinos , 2003, DOI: 10.1590/S1517-106X2003000200005
Abstract: this article treats the current dislike in france for malraux, author of the novel man's fate, by discussing the almost complete absence of reference to his works by roland barthes. malraux is considered to have abandoned his leftist revolutionary stance after accepting political office next to minister de gaulle. barthes almost never mentions malraux or does it in order to discredit the writer and the minister he works for. this article tries, through fine irony, to offer an alternative to barthes' view and attempts to recover malraux's place in the panorama of french literature from the 1930's.

Religion and University
Dieudonné Datonou
Alteridad : Revista de Educación , 2011,
Abstract: Ante los alcances y las perspectivas de progresos de la ciencia y de la técnica, muchos, postulando que la religión está relacionada con fenómenos o aspectos de la vida y del mundo transitoriamente inexplicado, profetizaron que ella, paulatinamente, desplazaría sus fronteras a medida de los avances de la racionalidad científica, hasta desaparecer del horizonte del ser humano. La corriente filosófica del iluminismo había abierto ese camino y, entusiasmados por la Revolución industrial de los siglos XVIII-IXX en Europa, algunos anunciaron el declinar de la religión. El filosofo Karl Marx y sus seguidores difundieron bastante esa opinión, presentando la religión no solo como una realidad prelógica, sino también como un opio, una esclavitud para el ser humano.
Corporate Groups under the Laws of Rwanda: An Economic Reality without Legal Identity  [PDF]
Dieudonné Nzafashwanayo
Beijing Law Review (BLR) , 2016, DOI: 10.4236/blr.2016.72010
Abstract: Corporate groups have become common in and dominate the business world. They emerge from reconfiguration of large companies into a multitude of subsidiaries from the simplest radial structure to the complex pyramidal and circular structures, in all structures, all companies within the group being ultimately held by a single parent company. Despite the omnipresence of corporate groups and their place in business world, their legal nature is yet to be seen whereas the use of this structure (corporate groups) to conduct business leads to tensions with traditional corporate law notions of each company being a separate legal entity and the blurring of lines of independence and modus operandi of corporate groups can be dangerous for creditors, employees, minority shareholders and pose challenges for regulators (such as taxman and anti-trust regulatory bodies) assessing the status of transactions conducted within the group. This article will discuss the notion of corporate groups under the laws of Rwanda and will argue that, albeit the fact that corporate groups (under traditional principles of corporate law) do not have legal existence, in some branches of law such as tax, anti-trust, employment, banking and finance law, the same have got a legal recognition and are treated as such. However, it will be submitted that the tenor of and challenges posed by corporate groups call for a clear recognition and stand of the legislator on the legal nature of corporate groups.
Modeling the wait time of a hierarchical system: Case study of an Internal Medicine unit
International Journal of Engineering and Technology , 2011,
Abstract: All, such as industrial production (Manufacturing companies), health units are hierarchical at the level of organization. This arrangement permits them to response efficiently to an event in occurrence, such as a patient whom appropriate care has to be dispensed. The quick reaction of the medical unit when faced with a problem is not only an indicator of its reactivity, but also an indicator of its performance.In this article, we propose to model the reaction of a medical unit in relationship to parameters, notably the reference periods of the different levels at which decisions are made. We define and express subsequently, the wait times which is a source of delay in the treatment process of a patient from when he arrives. Then, we propose an algorithm which minimizes the wait time.
A tool to determine the quantity of components needed taking into consideration reject: application in a small agro-company
International Journal of Engineering and Technology , 2011,
Abstract: This project presents the realization of a tool to determine the raw material needs for small companies in the agricultural sector in Cameroon. The objective is to; eliminate stocking perishable raw materials by ordering the right quantities and just on time too. To attain this objective, we integrate technical and commercial information as well as consider damages (loss) in input and end products. We then apply this tool to a small enterprise that producesfruit juice.
