Optical Coherence in Astrophysics: The Powerful Alternative of Big Bang

Journal of Modern Physics 2013年第8期4卷 197-206页

作者： jacques moret-bailly Physics Department University of Burgundy Dijon France

The coherence of the interaction of light with a collisionless gas (Einstein 1917) founds the theory of gas lasers. It is, for the understanding of universe, a simpler and more powerful tool than the big bang which requires questionable supplements (dark matter, MOND, etc.). The Impulsive Stimulated Raman Scattering (ISRS) redshifts gradually light pulses which cross excited atomic hydrogen H*, so that the redshift is a measure of the column density of H*. Thus, the distance of the hot stars, surrounded by much H*, is exaggerated by the use of Hubble’s law. Local exaggerated distances create voids in the maps of galaxies which become spongy. The interpretation of spectra of quasars, the periodicity of galaxy redshifts introduce an experimental “Karlsson’s constant” exactly computed by ISRS. The need for dark matter comes from the exaggeration of the distance, therefore the size of galaxies. Without dark matter, celestial mechanics provides a reliable distance of spiral galaxies. Coherence also introduces superradiance and mode competition that explain that only the limbs of Stromgren spheres are visible as circles maybe punctuated by an even number of dots: Too numerous, the figures assigned to gravitational lenses can be such limbs. The coincidence of the ignition of the rings of SNR1987A with the extinction of the star is due to a multiphoton coherent scattering of star light, which amplifies the superradiant emission of the rings. A blueshift of microwaves crossing H* resulting, between 10 and 15 AU, of the expansion of solar wind, explains the “anomalous acceleration” of Pioneer probes. All is obtained without any change in theories of standard spectroscopy.

Objective:To assess the prevalence of parasitic infections among patients attending Saint Camille Medical Centre and to estimate co-parasitic infections ***:From January to December 2009,stool samples were collected from 11 728 persons,aged from five months to 72 years and suffering from *** macroscopic description,the stools were examined by light microscopy to search for the presence of ***:From the 11 728 analyzed stools,6 154(52.47%) were infected with at least one *** frequently encountered were:Giardia intestinalis(43.47%),Entamoeba histolytica/Entamoeba dispar(30.74%) and Trichomonas irUestinalis(21.72%),while Hymenolepis nana(2.25%) was the most common ***-infections occurred in 22.34%*** the multi-infected samples,dual and triple infections accounted for 71.18%and 20.00%,*** irUestinalis for protozoan and Hymenolepis nana for helminths were the most implicated ***: This study confirms that intestinal parasites are still a public health problem in Burkina *** reduce the incidence of parasitic infections,it is necessary to promote the education of people so that they practice the rules of individual and collective hygiene.

Objective:To evaluate efficiency of HAART in the prevention of mother to child HIV ***:A longitudinal study was conducted on 1 300 women attending the antenatal service at Saint Camille Medical Centre from September 2010 to July *** HIV status of mothers was determined by rapid tests and *** results were confirmed by real-time *** was used to determine HIV status of children born from HIV-positive ***:Among 1 300 pregnant women tested for HIV,378 were *** were predominantly housewives(69.7%),and their mean age was(28.32±0.15) *** overall prevalence of HIV transmission from mother to child was 4.8%(18/378).This prevalence differed significantly from 0.0%(0/114) to 6.8%(18/264) in children born from mothers under HAART and those with mothers under New Prophylactic Protocol(ACT + 3TC + NVP),respectively(P< 0.01).Children’s mortality rate during the medical follow up was 1.3%(5/378).Among 16 women with HIV dubious status by ELISA,the Real Time PCR confirmed 2/16(12.5%) as HIV positive. Conclusions:The protocol of prevention of mother to children HIV transmission(PMTCT) is *** rate of HIV vertical transmission is significantly *** diagnosis determined by PCR of children born from HIV- positive mother is necessary and recommended in the context of PMTCT in Burkina *** also found that PCR is an effective tool to confirm HIV status in pregnant women.

Glucose-6-phosphate dehydrogenase(G6PD) deficiency is associated with asymptomatic malaria in a rural community in Burkina Faso

Objective:To investigate 4 combinations of mutations responsible for glucose-6—phosphate dehydrogenase(G6PD) deficiency in a rural community of Burkina Faso,a malaria endemic ***:Two hundred individuals in a rural community were genotyped for the mutations A376 G.G202A,A542 T,G680T and T968 C using TaqMan single nucleotide polymorphism assays and polymerase chain reaction followed by restriction fragment length ***:The prevalence of the G6 PD deficiency was 9.5%,in the study *** was significantly higher in men compared to women(14.23%vs 6.0%,P=0.049).The 202A/376 G G6PD Awas the only deficient variant *** falciparum asymptomatic parasitemia was significantly higher among the C6PD-non—deficient persons compared to the G6PD-deficient(P<0.001).The asymptomatic parasitemia was also significantly higher among G(SPI) nondeficient compared to C6PD—heterozygous females(P<0.001).Conclusions:This study showed that the G6 PD A- variant associated with protection against asymptomatic malaria in Burkina Faso is probably the most common deficient variant.
