Nutritional Status of Tuberculous Children Diagnosed and Treated in an Urban Area in DR Congo  [PDF]
Bafwafwa Ntumba Don Dieu, Kanteng A. Wakamb Gray, Mutombo Mulangu Augustin, Lukamba Mbuli Robert, Tshikamba Erick, Wembonyama Okitotsho Stanislas, Luboya Numbi Oscar
Open Access Library Journal (OALib Journal) , 2017, DOI: 10.4236/oalib.1103557
Introduction: Tuberculosis and malnutrition are major health problems in DR Congo, and children are particularly vulnerable. The objective of this study is to determine the incidence of malnutrition in tuberculous children in DR Congo and to identify the associated factors. Methodology: A cross sectional study was conducted, and concerned 22 Tuberculosis Diagnosis and Treatment Centers (TDTCs). It was carried out over a period from 2013 to 2015 and involved 717 tuberculosis children less than 15 years of age. Nutritional status was assessed on the basis of the values of the Z-score Weight for age (global malnutrition) according to the NCHS curves. Results: Tuberculosis incidence was 8.2%. The prevalence of underweight (<﹣2 z-score) is 20.8%, of which 8.4% is severely malnourished (<﹣3 z-score). An age of less than 60 months is significantly associated with poor nutritional status (OR = 0.3, CI 0.2 - 0.5). TB-HIV co-infection is significantly associated with poor nutritional status (OR = 0.4, CI 0.2 - 0.6). It was noticed that the outcome is favorable (recovery) in patients with good nutritional status (OR = 12, CI 8.0 - 18.9). Conclusion: Underweight is present in Congolese tuberculosis children. An adequate nutritional policy is needed to improve the prognosis of the disease.
Pairings of Sheaves of $\mathcal{A}$-Modules through Bilinear $\mathcal{A}$-Morphisms
A. Mallios,PP Ntumba
Mathematics , 2008,
Abstract: It is proved that for any free $\mathcal{A}$-modules $\mathcal{F}$ and $\mathcal{E}$ of finite rank on some $\mathbb{C}$-algebraized space $(X, \mathcal{A})$ a \textit{degenerate} bilinear $\mathcal{A}$-morphism $\Phi: \mathcal{F}\times \mathcal{E}\longrightarrow \mathcal{A}$ induces a \textit{non-degenerate} bilinear $\mathcal{A}$-morphism $\bar{\Phi}: \mathcal{F}/\mathcal{E}^\perp\times \mathcal{E}/\mathcal{F}^\perp\longrightarrow \mathcal{A}$, where $\mathcal{E}^\perp$ and $\mathcal{F}^\perp$ are the \textit{orthogonal} sub-$\mathcal{A}$-modules associated with $\mathcal{E}$ and $\mathcal{F}$, respectively. This result generalizes the finite case of the classical result, which states that given two vector spaces $W$ and $V$, paired into a field $k$, the induced vector spaces $W/V^\perp$ and $V/W^\perp$ have the same dimension. Some related results are discussed as well.
Abstract Geometric Algebra. Orthogonal and Symplectic Geometries
PP Ntumba,Ac Orioha
Mathematics , 2008,
Abstract: Our main interest in this paper is chiefly concerned with the conditions characterizing \textit{orthogonal and symplectic abstract differential geometries}. A detailed account about the sheaf-theoretic version of the \textit{symplectic Gram-Schmidt theorem} and of the \textit{Witt's theorem} is also given.
On the endomorphisms of some sheaves of functions
Patrice P. Ntumba
Mathematics , 2013,
Abstract: Given a $C^\infty$ real manifold $X$ and $\mathcal{C}^m_X$ its sheaf of $m$-times differentiable real-valued functions, we prove that the sheaf $\mathcal{D}^{m, r}_X$ of differential operators of order $\leq m$ with coefficient functions of class $C^r$ can be obtained in terms of the sheaf $\mathcal{H}om_{\mathbb{R}_X}(\mathcal{C}^m_X, \mathcal{C}^r_X)$ of morphisms of $\mathcal{C}^m_X$ into $\mathcal{C}^r_X$. The superscripts $m$ and $r$ are integers.
Cofibrations in the Category of Frolicher Spaces. Part I
B. Dugmore,PP. Ntumba
Mathematics , 2007,
Abstract: Cofibrations are defined in the category of Fr\"olicher spaces by weakening the analog of the classical definition to enable smooth homotopy extensions to be more easily constructed, using flattened unit intervals. We later relate smooth cofibrations to smooth neighborhood deformation retracts. The notion of smooth neighborhood deformation retract gives rise to an analogous result that a closed Fr\"olicher subspace $A$ of the Fr\"olicher space $X$ is a smooth neighborhood deformation retract of $X$ if and only if the inclusion $i: A\hookrightarrow X$ comes from a certain subclass of cofibrations. As an application we construct the right Puppe sequence.
On $\mathcal A$-Transvections and Symplectic $\mathcal A$-Modules
Patrice P. Ntumba
Mathematics , 2009,
Abstract: In this paper, building on prior joint work by Mallios and Ntumba, we show that $\mathcal A$-\textit{transvections} and \textit{singular symplectic }$\mathcal A$-\textit{automorphisms} of symplectic $\mathcal A$-modules of finite rank have properties similar to the ones enjoyed by their classical counterparts. The characterization of singular symplectic $\mathcal A$-automorphisms of symplectic $\mathcal A$-modules of finite rank is grounded on a newly introduced class of pairings of $\mathcal A$-modules: the \textit{orthogonally convenient pairings.} We also show that, given a symplectic $\mathcal A$-module $\mathcal E$ of finite rank, with $\mathcal A$ a \textit{PID-algebra sheaf}, any injective $\mathcal A$-morphism of a \textit{Lagrangian sub-$\mathcal A$-module} $\mathcal F$ of $\mathcal E$ into $\mathcal E$ may be extended to an $\mathcal A$-symplectomorphism of $\mathcal E$ such that its restriction on $\mathcal F$ equals the identity of $\mathcal F$. This result also holds in the more general case whereby the underlying free $\mathcal A$-module $\mathcal E$ is equipped with two symplectic $\mathcal A$-structures $\omega_0$ and $\omega_1$, but with $\mathcal F$ being Lagrangian with respect to both $\omega_0$ and $\omega_1$. The latter is the analog of the classical \textit{Witt's theorem} for symplectic $\mathcal A$-modules of finite rank.
Medical Food to Stop the Progression of Parkinson’s Disease  [PDF]
Don McCammon
Advances in Parkinson's Disease (APD) , 2014, DOI: 10.4236/apd.2014.32003

No progress has been made in the development of drugs to stop the progression of Parkinson’s Disease. Here the author has presented a novel approach to stopping the disease using a dietary supplement primarily composed of Mannitol. In vivo animal studies have shown that Mannitol was able to break up alpha-synuclein clusters and restore functioning in transgenic drosophila and mice. The author, who has Parkinson’s, used himself as a subject and was able to achieve similar results.

Fundamentals for Symplectic $\mathcal{A}$-modules
Anastasios Mallios,Patrice P. Ntumba
Mathematics , 2007,
Abstract: Sheaf theoretically based Abstract Differential Geometry incorporates and generalizes all the classical differential geometry. Here, we undertake to partially explore the implications of Abstract Differential Geometry to classical symplectic geometry. The full investigation will be presented elsewhere.
Symplectic Reduction of Sheaves of $\mathcal{A}$-modules
A. Mallios,P. P. Ntumba
Mathematics , 2008,
Abstract: Given an arbitrary sheaf $\mathcal{E}$ of $\mathcal{A}$-modules (or $\mathcal{A}$-module in short) on a topological space $X$, we define \textit{annihilator sheaves} of sub-$\mathcal{A}$-modules of $\mathcal{E}$ in a way similar to the classical case, and obtain thereafter the analog of the \textit{main theorem}, regarding classical annihilators in module theory, see Curtis[\cite{curtis}, pp. 240-242]. The familiar classical properties, satisfied by annihilator sheaves, allow us to set clearly the \textit{sheaf-theoretic version} of \textit{symplectic reduction}, which is the main goal in this paper.
La sécurité à l’heure des nouvelles technologies de contr le : l’exemple de la vidéosurveillance en France / Security at the time of the new control technology : the example of video surveillance in France
Dieu Fran?ois
Rivista di Criminologia, Vittimologia e Sicurezza , 2010,
Abstract: The author of this article makes some preliminary remarks in order to outline, from a general point of view, the problem of the so-called “new control technology”.Then, he deals with the impact of this technology on creating security, taking the French situation as an example, even if most of these observations can be made about other European countries.
