Abstract: Background During the last eight years, North and South Kivu, located in a lake area in Eastern Democratic Republic of Congo, have been the site of a major volcano eruption and of numerous complex emergencies with population displacements. These conditions have been suspected to favour emergence and spread of cholera epidemics. Methodology/Principal Findings In order to assess the influence of these conditions on outbreaks, reports of cholera cases were collected weekly from each health district of North Kivu (4,667,699 inhabitants) and South Kivu (4,670,121 inhabitants) from 2000 through 2007. A geographic information system was established, and in each health district, the relationships between environmental variables and the number of cholera cases were assessed using regression techniques and time series analysis. We further checked for a link between complex emergencies and cholera outbreaks. Finally, we analysed data collected during an epidemiological survey that was implemented in Goma after Nyiragongo eruption. A total of 73,605 cases and 1,612 deaths of cholera were reported. Time series decomposition showed a greater number of cases during the rainy season in South Kivu but not in North Kivu. Spatial distribution of cholera cases exhibited a higher number of cases in health districts bordering lakes (Odds Ratio 7.0, Confidence Interval range 3.8–12.9). Four epidemic reactivations were observed in the 12-week periods following war events, but simulations indicate that the number of reactivations was not larger than that expected during any random selection of period with no war. Nyiragongo volcanic eruption was followed by a marked decrease of cholera incidence. Conclusion/Significance Our study points out the crucial role of some towns located in lakeside areas in the persistence of cholera in Kivu. Even if complex emergencies were not systematically followed by cholera epidemics, some of them enabled cholera spreading.

Abstract: Motor impairment of cerebral origin is a syndrome that induces a reduction in activity, the origin of which is brain injury or a non-progressive and definitive abnormality occurring in a developing immature brain. Motor disability, spastic, dyskinetic or ataxic, is often associated with sensory, cognitive, sensory and behavioral disorders with or without epileptic disease. View of accidental discoveries of corpus callosum abnormalities, most often asymptomatic or associated with psychomotor retardation, epilepsy, neurological disorders or cardiomyopathy, a high technical platform must be available for its diagnosis. We report in this article the case of a 7-year-old boy followed at the neuropsychiatric center Joseph Guislain of the Brothers of Charity of Lubumbashi in Congo (DRC) since 2016 for generalized tonic-clonic seizures, in whom the diagnosis of cerebral palsy on cyst of corpus callosum and in the right parietal lobe, as well as cardiopathy was posed during its consultation in September 2017. This case was published with parental consent.
Tuberculose pulmonaire révélée par un purpura thrombopénique chez l’enfant - à propos d’un cas clinique observé au service de pédiatrie des Cliniques Universitaires de Lubumbashi

Pan African Medical Journal , 2012,
Abstract: Nous rapportons le cas d’un enfant de 7 ans, de sexe masculin ayant présenté un purpura thrombopénique avec épistaxis, hématémèse, otorragies et pétéchies généralisées. Durant la même hospitalisation, nous avons mis en évidence une tuberculose pulmonaire documentée par la présence de bacilles acido-alcoolo résistants à l’examen des crachats. Nous avons observé une majoration du taux de plaquettes en une semaine de corticothérapie intraveineuse à haute dose, avant l’instauration d’une poly chimiothérapie antituberculeuse. Nous rappelons également la controverse que suscite la prise en charge de cette association rarement rapportée.

Abstract:
BACKGROUND AND AIM: Although admission hyperglycemia has been reported to be associated with unfavorable outcomes in acute stroke, little is known about this association in sub-Saharan Africa. Therefore, the aim of the present study was to assess the prognostic significance of admission hyperglycemia in the acute phase of stroke in Congolese patients. METHODS: In a multicenter prospective cohort study, consecutive patients with acute stroke were examined in 5 Emergency Rooms or Intensive Care Units of Kinshasa between July 15th, 2017 and March 15th, 2018. The severity of stroke was assessed at admission using the Glasgow Coma Scale. Stress hyperglycemia was defined as random blood glucose levels at admission > 140 mg/dL in patients without known type 2 diabetes mellitus (T2DM). The endpoint was 10-day all-cause in-hospital mortality. Survival (time-to-death) curves were built using the Kaplan Meier methods. Cox proportional analysis was used to identify predictors of 10-day all-cause in-hospital mortality. The predictive performance of blood glucose level
Ego Depletion and the Humean Theory of Motivation  [PDF]
Patrick Fleming
Open Journal of Philosophy (OJPP) , 2014, DOI: 10.4236/ojpp.2014.43042
Abstract:

By what capacities do human beings engage in intentional action? Humeans about motivation claim that the source of all action is desire. Volitionalists claim that action has two distinct sources, one in the will and one in desire. Recent work suggests that volitionalism has some empirical support. Roy F. Baumeister and colleagues have argued for a phenomenon called “ego depletion”. They argue that some aspect of the self exerts volition in a number of different contexts. The main evidence for this claim is that experimental subjects who engage in acts of self-regulation are less likely to engage in similar actions on later tests. The evidence calls for a reformulation of the Humean theory, not a rejection of it. And the reformulation is one that still has interest for metaethics. Many philosophers are interested in the Humean theory of motivation because they believe that it has implications for the correct theory of normative practical reasons. Here I argue that if the Humean theory of motivation was ever a threat to the objectivity of morality, it still is.

Rain Attenuation Effects on 2.6 GHz WiMAX Networks Deployment in Ghana  [PDF]
Patrick Fiati
World Journal of Engineering and Technology (WJET) , 2015, DOI: 10.4236/wjet.2015.33009
Abstract: WiMAX communication systems operating at 2.6 G frequencies are used for broadband multimedia and internet based services. At these frequencies, the signal will be affected by various propagation impairments such as rain attenuation, cloud attenuation, tropospheric scintillation, ionospheric scintillation, water vapour attenuation, and rain and ice depolarization. Among all the pro-pagation impairments, rain attenuation is the most important and critical parameter. In this research, rain attenuation is calculated at KNUST, Kumasi using ITU-R rain attenuation model. The preliminary results of the work will be used to calculate the attenuation experimentally and comparison can be made, which helps to develop a new rain attenuation model at 2.6 G bands. Rain attenuation is an important aspect of signal propagation above 2.6 GHz frequency. The attenuation time series generation from point rain rate measurement is crucial due to unavailability of actual signal measurements. In this research, a simple and realistic approach has been demonstrated for better estimation of rain attenuation using WiMAX-band signal propagation data and ground rain rate measurements in Ghana. The ITU-R model of rain attenuation has been modified by incorporating an effective slant path model. The effective slant path has been estimated and modeled in terms of a power-law relationship of rain rate data of 2007-2008. The methodology has been validated with the measured data of 2014. Comparison with ITU-R and GMET clearly demonstrates the improved predictability of the proposed model at the present tropical location.
RapidSCAT Sigma-0 and Tb Measurements Validation  [PDF]

Abstract: Scatterometer Radar Backscatter Calibration since the first SeaSat-A Satellite Scatterometer (Birer et al., 1982), the Amazon tropical rain forest has been recognized as a spatially large extent, homogeneous radar calibration target. During the commissioning of NSCAT (1996) and later QuikSCAT (1999), CFRSL worked with the JPL Scatterometer Cal/Val team to perform normalized radar cross section (Sigma-0) calibrations using the Amazon (see Zec et al., 1999-A and 1999-B) [1]. It is important to continue this activity using RapidSCAT to validate the Sigma-0 measurement provided in the L-1A data product, and moreover the time series of these backscatter observations can be used to establish an improved Ku-band Amazon calibration site for future on-orbit radar calibration [2]. Unfortunately, the Amazon radar backscatter (Sigma-0) exhibits a time of day dependence that is not well characterized, and for the sun-synchronous polar orbiting satellites (SeaSat-A, ADEOS-I and QuikSCAT), the observations occur at specific times of day, during the morning and night passes. But now with the low-earth-orbit of the ISS, there will be an orderly orbit precession, which allows the region to be uniformly sampled over the 24-hour period [3]. Also, since the RapidSCAT employs a conical scanning geometry, we can examine the isotropic nature of Amazon backscatter established by Zec’s (1998-A) analysis of NSCAT and later (1999-B) of QuikSCAT observations [4]. Thus, observations, collected over the RapidSCAT two-year mission will sample the Amazon with high spatial/temporal resolution, as a function of time of day, and over seasons. We propose to analyze these data to develop a high spatial resolution Sigma-0 Amazon map that can be used by future satellite radar missions.

Open Access Library Journal (OALib Journal) , 2018, DOI: 10.4236/oalib.1104748
Abstract:
This paper aims at highlighting how English is gaining momentum on tiptoe in the Democratic Republic of Congo through mining companies as its gateways, although the country traditionally belongs to Kachru’s Expanding Circle, and to which extent these mining companies, which to a large extent are branches of multinational companies, cope with language use and management within multilingual workplaces. The insights gained from various companies demonstrate that the adoption of English alone as a corporate language is not enough and that multilingual communication would be the best practice to overcome language barriers within these workplaces.
