Abstract:
Valvular heart diseases during pregnancy are complex with symptoms likely to affect patient’s life quality, and endanger both mother’s and child’s life. Our survey aims at studying the combination of valvular heart diseases with pregnancy at University Hospital Yalgado Ouedraogo. This study was a cross-sectional study conducted from January 1st, 2015 to March 31st, 2016 in the delivery room of gynecology and obstetrics department. Inclusion criteria were: the presence of acquired and known valvular heart diseases followed-up or not; suspected valvular heart disease confirmed by a Doppler echocardiography and patient’s consent to take part to the study. Twelve patients were involved in the study. The average age was 27.5 ± 3.9 years (extremes of 21 and 34 years). The average gestational age at the delivery time was 35 ± 4.7 weeks of amenorrhea with extremes reaching 25 and 39 weeks. None of the study patients were previously followed-up and treated for valvular heart diseases before pregnancy. Mitral disease was found among four patients. Seven cases had vaginal delivery. Two cases of spontaneous abortion were observed. We had seven hypotrophy newborns with an average weight of 2360 g at birth. Two patients suffering from congestive heart failure with a full type arrhythmia by atrial fibrillation were hospitalized in cardiology department. No death was reported during our study. Rheumatic valvular diseases are common among pregnant women. The cardiologist should plan pregnancies of patients suffering from valvular heart diseases. Treatment of those patients goes through the prevention of acute rheumatoid arthritis including a joint collaboration between cardiologists and gynecologists.

Abstract:
Objective: Our study aimed at assessing the quality of life (QoL) of patients treated for chronic heart failure (HF), and analyzing the impact of certain factors on that QoL, in the cardiology department of Yalgado Ouédraogo University Hospital of Ouagadougou. Means and Method: It was a descriptive cross-sectional study, performed over a six-month period from May to October 2016. In the study, patients with age over 18 years were included, followed up for chronic HF for at least six months in the outpatient unit, from January 1st to December 31st 2015. The questionnaire “Minnesota Living with Heart Failure” was used to assess the QoL. Results: Two hundred and four patients were enrolled. Most of them were living in Ouagadougou (82.8%). Sex ratio was 0.98, and mean age was 56.06 16.37 years. The mean overall QoL score was 17.8 16.5. QoL was considered good in its three dimensions, in more than 70% of patients. Looking at the mean scores, the male patients, the patients living in rural and semi-urban areas, the patients with impaired left ventricular ejection fraction and those with severe or end-stage renal failure had significant QoL impairment. Multiple linear regression reported significant correlation between QoL impairment and the following factors (p value < 0.05 for all variables): marital life, number of hospitalizations for acute HF, and NYHA functional stage. Conclusion: Marital life, number of hospitalizations for acute decompensation, and NYHA functional stage were predictive factors of QoL impairment. MLHF questionnaire should be commonly used to assess the efficiency of HF management. Self administration instead of assistance in filling the questionnaire, could insure a more objective valuation of QoL.
All-in-One: Space-Time Body, Function and Metric — A Fundamentally New Approach to Computation  [PDF]
Hermann von Issendorff
Int'l J. of Communications, Network and System Sciences (IJCNS) , 2013, DOI: 10.4236/ijcns.2013.65029
Abstract:

Every algorithm which can be executed on a computer can at least in principle be realized in hardware, i.e. by a discrete physical system. The problem is that up to now there is no programming language by which physical systems can constructively be described. Such tool, however, is essential for the compact description and automatic production of complex systems. This paper introduces a programming language, called Akton-Algebra, which provides the foundation for the complete description of discrete physical systems. The approach originates from the finding that every discrete physical system reduces to a spatiotemporal topological network of nodes, if the functional and metric properties are deleted. A next finding is that there exists a homeomorphism between the topological network and a sequence of symbols representing a program by which the original nodal network can be reconstructed. Providing Akton-Algebra with functionality turns it into a flow-controlled general data processing language, which by introducing clock control and addressing can be further transformed into a classical programming language. Providing Akton-Algebra with metrics, i.e. the shape and size of the components, turns it into a novel hardware system construction language.

The Cognitive Gap, Neural Darwinism & Linguistic Dualism —Russell, Husserl, Heidegger & Quine  [PDF]
Hermann G. W. Burchard
Open Journal of Philosophy (OJPP) , 2014, DOI: 10.4236/ojpp.2014.43032
Abstract:

Guided by key insigths of the four great philosophers mentioned in the title, here, in review of and expanding on our earlier work (Burchard, 2005, 2011), we present an exposition of the role played by language, & in the broader sense, λογοζ, the Logos, in how the CNS, the brain, is running the human being. Evolution by neural Darwinism has been forcing the linguistic nature of mind, enabling it to overcome & exploit the cognitive gap between an animal and its world by recognizing environmental structures. Our work was greatly influenced by Heidegger’s lecture notes on metaphysics (Heidegger, 1935). We found agreement with recent progress in neuroscience, but also mathematical foundations of language theory, equating Logos with the mathematical concept of structure. The mystery of perception across the gap is analyzed as radiation and molecules impinging on sensory neurons that carry linguistic information about gross environmental structures, and only remotely about the physical reality of elementary particles. The most important logical brain function is Ego or Self, guiding the workings of the brain as a logos machine. Ego or Self operates from neurons in frontopolar cortex with global receptive fields. The logos machine can function only by availing itself of global context, its internally stored noumenal cosmos NK, and the categorical-conceptual apparatus CCA, updated continually through the neural default mode network (Raichle, 2005). In the Transcendental Deduction, Immanuel Kant discovered that Ego or Self is responsible for conscious control in perception relying on concepts & categories for a fitting percept to be incorporated intoNK. The entire CNS runs as a “movie-in-the-brain” (Parvizi & Damasio, 2001), at peak speed processing simultaneously in a series of cortical centers a stack of up to twelve frames in gamma rhythm of 25 ms intervals. We equate global context, or NK, with our human world, Heidegger’s Dasein being-in-the-world, and are able to demonstrate that the great philosopher in EM parallels neuro-science concerning the human mind.

Modeling of a Cubic Antiferromagnetic Cuprate Super-Cage  [PDF]
Hans Hermann Otto
World Journal of Condensed Matter Physics (WJCMP) , 2015, DOI: 10.4236/wjcmp.2015.53018
Abstract: Convex polyhedral cuprate clusters are being formed through lateral frustration when the a and c lattice parameters of the tetragonal ACuO2 infinite layer structure will become identical by substitution of a large cation (A = Ba2+). However, the corner-shared CuO2 plaquettes of the infinite network suffer a topotactic rearrangement forming edge-connected units, for instance Cu18O24 cages (polyhedron notation [4641238]) with <90° ferromagnetic super-exchange interaction as found in cubic BaCuO2. Cage formation via a hypothetical tetragonal BaCuO2 compound (space group P4/ nmm) will be discussed. The possibility to construct a cuprate super-cage with m3m symmetry (polyhedron notation [4641242438]) is being reported. This super-cage still consists of edge-connected CuO2 plaquettes when fully decorated with copper ions, but with different curvatures, arranged in circles of 9.39 ? of diameter with 139.2° Cu-O-Cu antiferromagnetic super-exchange interaction. On the one hand, the realization of such a quite stable cuprate super-cage as a candidate for high-Tc superconductivity depends on whether a template of suitable size such as the \"\"cation or C(CH3)4 enables its formation, and on the other hand the cage can further be stabilized by highly charged cations located along the [111] direction. Synthesis options will be proposed based on suggested cage formation pathways. An X-ray powder pattern was calculated for a less dense cluster structure of Im3m space group with a lattice parameter of a = 14.938 ? and two formula units of Cu46O51 to facilitate future identification. Characteristic X-ray scattering features as identification tool were obtained when the electron distribution of the hollow polyhedron was approximated with electron density in a spherical shell.
Pyroelectric Bi5-x(Bi2S3)39I12S: Fibonacci Superstructure, Synthesis Options and Solar Cell Potential  [PDF]
Hans Hermann Otto
World Journal of Condensed Matter Physics (WJCMP) , 2015, DOI: 10.4236/wjcmp.2015.52010
Abstract: Previously, synthetic hexagonal bismuth sulfide iodide (polar space group P63, a = 15.629(3) ?, c = 4.018(1) ?, Z = 2) has been described by the rather unsatisfactory fractional formula Bi19/3IS9 [1]-[3]. A redetermination of the structure using old but reliable photographic intensity data indicated the presence of additional split positions and reduced atomic occupancies. From the observed pattern of this “averaged” structure a consistent model of a superstructure with lattice parameters of a' = √13·a = 56.35(1) ?, c' = c, and a formula Bi5-x(Bi2S3)39I12S emerged, with 2 formula units in a cell of likewise P63 space group. Structural modulation may be provoked by the space the lone electron pair of Bi requires. When Bi on the 0, 0, z position of the “averaged” cell is transferred to two general six-fold sites and one unoccupied twofold one of the super-cell, more structural stability is guaranteed due to compensation of its basal plane dipole momentum. Owing to the limited intensity data available, more details of the superstructure are not accessible yet. Some physical properties and solar cell application are discussed together with suggestions of ambient temperature synthesis routes of c-axis oriented nano-rod sheets.
Philosophy and Science, the Darwinian-Evolved Computational Brain, a Non-Recursive Super-Turing Machine & Our Inner-World-Producing Organ  [PDF]
Hermann G. W. Burchard
Open Journal of Philosophy (OJPP) , 2016, DOI: 10.4236/ojpp.2016.61002
Abstract: Recent advances in neuroscience lead to a wider realm for philosophy to include the science of the Darwinian-evolved computational brain, our inner world producing organ, a non-recursive super-Turing machine combining 100B synapsing-neuron DNA-computers based on the genetic code. The whole system is a logos machine offering a world map for global context, essential for our intentional grasp of opportunities. We start from the observable contrast between the chaotic universe vs. our orderly inner world, the noumenal cosmos. So far, philosophy has been rehearsing our thoughts, our human-internal world, a grand painting of the outer world, how we comprehend subjectively our experience, worked up by the logos machine, but now we seek a wider horizon, how humans understand the world thanks to Darwinian evolution to adapt in response to the metaphysical gap, the chasm between the human animal and its environment, shaping the organism so it can deal with its variable world. This new horizon embraces global context coded in neural structures that support the noumenal cosmos, our inner mental world, for us as denizens of the outer environment. Kant’s inner and outer senses are fundamental ingredients of scientific philosophy. Several sections devoted to Heidegger, his lizard debunked, but his version of the metaphysical gap & his doctrine of the logos praised. Rorty and others of the behaviorist school discussed also.
Reciprocity Relation between the Mass Constituents of the Universe and Hardy’s Quantum Entanglement Probability  [PDF]
Hans Hermann Otto
World Journal of Condensed Matter Physics (WJCMP) , 2018, DOI: 10.4236/wjcmp.2018.82003
Abstract: In this short contribution, a reciprocity relation between mass constituents of the universe was explained governed by Hardy’s maximum entanglement probability of φ5 = 0.09017. While well explainable through a set-theoretical argumentation, the relation may also be a consequence of a coupling factor attributed to the normed dimensions of the universe. Also, very simple expressions for the mass amounts were obtained, when replacing the Golden Mean φ by the Archimedes constant π. A brief statement was devoted to the similarity between the E-Infinity Theory of El Naschie and the Information Relativity Theory of Suleiman. In addition, superconductivity was also linked with Hardy’s entanglement probability.
Super-Hydrides of Lanthanum and Yttrium: On Optimal Conditions for Achieving near Room Temperature Superconductivity  [PDF]
Hans Hermann Otto
World Journal of Condensed Matter Physics (WJCMP) , 2019, DOI: 10.4236/wjcmp.2019.91002
Abstract: Recently, many seminal papers deal with the syntheses, stability and superconducting properties of super-hydrides like LaH10 or YH10 under high pressure, reporting critical temperatures near room temperature. In the first run one will assume that the involved metal atoms contribute a number of 3 electrons to the pairing pool corresponding to their valence. However, another possibility may be that the cationic valence is somewhat smaller, for instance only 2.29, resulting in a nominal electron number per cation of σ0 = 0.229 ≈ 3/13 instead of 0.3. Then, we will have a numerical equality to the optimum hole number in the cuprate high-Tc superconductors, a number that reflects the fractal nature of electronic response in superconductors. However, if one still keeps up the oxidation state of +3 of lanthanum, one will need 13 hydrogen atoms to match the optimum σ0. Such composition may be found at the phase boundary between the observed LaH10 and LaH16 phases. Partial ionic replacement is suggested to shift the super-hydride composition into the σ0 optimum. Micro-structural phenomena such as multiple twinning and ferroelastic behavior as observed with cuprates may also influence the superconductivity of super-hydrides. Finally, epitaxial growth of super-hydrides onto a specially cut diamond substrate is proposed.
X-Ray Powder Diffraction: Why Not Use CuKβ Radiation?  [PDF]
Hans Hermann Otto
Journal of Analytical Sciences, Methods and Instrumentation (JASMI) , 2018, DOI: 10.4236/jasmi.2018.83004
Abstract: Cu radiation with a wavelength of λ = 1.3923 ? is recommended for crystal structure determination from X-ray powder diffraction using the Rietfeld method. A highly sensitive image plate detector is able to collect enough intensity to record a brilliant X-ray powder pattern in a reasonable time, compared to CuKα1 radiation used today. Especially atomic displacement coefficients could be determined more precisely with the much greater number of reflections recorded. A double-radius Guinier camera attached to a micro-focus rotating anode tube ensures increased brilliance besides high resolution. A simple construction specification is presented to make smart cylindrically bent Ge(111) or Si(111) X-ray monochromators that deliver focused Cu radiation. The highly linear response of image plate detectors allows removing of fluorescence radiation simply as background of the pattern. The proposed equipment is a cost-efficient alternative to a liquid gallium-metal-jet X-ray source with maximum power load and a similar wavelength of λ(GaKα1) = 1.34013 ?.
