On Prospects for Exploration of Supersymmetry in Double Beta Decay Experiments
V. A. Bednyakov,V. B. Brudanin,S. G. Kovalenko,Ts. D. Vylov
Physics , 1998, DOI: 10.1142/S0217732397000236
Abstract: We analyze constraints on the parameters of the R-parity violating supersymmetry which can be extracted from non-observation of the neutrinoless nuclear double beta decay ($0\nu\beta\beta$) at a given half-life lower bound. Our analysis covers a large class of phenomenologically viable R-parity violating SUSY models. We introduce special characteristics: the SUSY sensitivity of a $\beta\beta$ decaying isotope and the SUSY reach of a $0\nu\beta\beta$ experiment. The former provides a physical criterion for a selection of the most promising isotopes for SUSY searches and the latter gives a measure of success for a $0\nu\beta\beta$ experiment in exploring the R-parity violating SUSY parameter space. On this basis we discuss prospects for exploration of supersymmetry in various $0\nu\beta\beta$ experiments.

A. G. Beda,V. B. Brudanin,E. V. Demidova,V. G. Egorov,M. G. Gavrilov,M. V. Shirchenko,A. S. Starostin,Ts. Vylov
Physics , 2007, DOI: 10.1134/S1063778807110063
Abstract: The first result of the neutrino magnetic moment measurement at the Kalininskaya Nuclear Power Plant (KNPP) with the GEMMA spectrometer is presented. An antineutrino-electron scattering is investigated. A high-purity germanium detector of 1.5 kg placed 13.9 m away from the 3 GW reactor core is used in the spectrometer. The antineutrino flux is $2.73\times 10^{13} \nu_e / cm^2 / s$. The differential method is used to extract the $\nu$-e electromagnetic scattering events. The scattered electron spectra taken in 6200 and 2064 hours for the reactor ON and OFF periods are compared. The upper limit for the neutrino magnetic moment $\mu_\nu < 5.8\times 10^{-11}$ Bohr magnetons at 90{%} CL is derived from the data processing.
GEMMA experiment: three years of the search for the neutrino magnetic moment
A. G. Beda,V. B. Brudanin,E. V. Demidova,V. G. Egorov,D. V. Medvedev,M. V. Shirchenko,A. S. Starostin,Ts. Vylov
Physics , 2009, DOI: 10.1134/S1547477110060063
Abstract: The result of the 3-year neutrino magnetic moment measurement at the Kalinin Nuclear Power Plant with the GEMMA spectrometer is presented. Antineutrino-electron scattering is investigated. A high-purity germanium detector of 1.5 kg placed at a distance of 13.9 m from the 3 GW(th) reactor core is used in the spectrometer. The antineutrino flux is 2.7E13 1/scm/s. The differential method is used to extract (nu-e) electromagnetic scattering events. The scattered electron spectra taken in 5184+6798 and 1853+1021 hours for the reactor ON and OFF periods are compared. The upper limit for the neutrino magnetic moment < 3.2E-11 Bohr magneton at 90% CL is derived from the data processing.
The Oscillator Strengths of H2+, 1sσ_{g}-2pσ_{u}, 1sσ_{g}-2pπ_{u}
Ts. Tsogbayar,Ts. Banzragch
Physics , 2010,
Abstract: The oscillator strengths of the $H^+_2$ molecular ion, $1s\sigma_{g}-2p\sigma_{u}$, $1s\sigma_{g}-2p\pi_{u}$ are calculated within the Born-Oppenheimer approximation. The variational expansion with randomly chosen exponents has been used for numerical studies. The oscillator strengths obtained for the transitions $1s\sigma_{g}-2p\sigma_{u}$, $1s\sigma_{g}-2p\pi_{u}$ of $H^+_2$ are accurate up to ten significant digits. Results are given for the internuclear distances between 0.10 and 20.0 a.u.
The complexities in the classification of protozoa: a challenge to parasitologists
TS Imam
Bayero Journal of Pure and Applied Sciences , 2009,
Abstract: This paper revisits the controversial issues bedevilling classification of the parasitic protozoa as a result of varying interest by different scientists belonging to protozoology and parasitology axes. In recent years, the availability of a number of molecular markers has made it possible to analyse relationships between protozoa that would not have been possible using morphological characters alone. Three terms are currently widely used: Protozoa, Protoctista, and Protista. However, parasitologists tend to be very conservative and the term Protozoa is now almost universally used by scientist working with those parasitic unicellular organisms that infect humans and domesticated animals. With the creation of 5 kingdoms, status of Protozoa was raised to that of a kingdom, which formerly was a Phylum. Thus, the subordinate groups automatically became Phyla. The increase in the number of parasitic protozoa recorded from humans and the accumulation of knowledge about their biology led to the creation of taxonomic and other groupings at the subgenus and subspecie levels. Corliss (1994) in his scheme has used both traditional and contemporary approaches and has attempted to retain familiar names as far as possible. It is important that any classification should reflect modern thinking about the classification as a whole, while retaining sufficient traditional material so as to permit every reference to information retrieval systems
Assessment of Heavy Metals Concentrations in the Surface Water of Bompai-Jakara Drainage Basin, Kano State, Northern Nigeria
TS Imam
Bayero Journal of Pure and Applied Sciences , 2012,
Abstract: This work aimed at assessing the concentrations of heavy metals in the surface water of Bompai-Jakara drainage basin. The points of sampling were designated as A, B, C, D, E, and F. Acid-washed (1L) plastic bottles were used in collecting the water samples, which were then digested using nitric acid (HNO3). The digested samples were analyzed for Fe, Cr, Cu, Zn and Pb using Atomic Absorption Spectrophotometer (Model IL250). The seasonal sequence of heavy metals concentrations showed Zn>Fe>Cr>Cu>Pb and Fe>Zn>Cr>Cu>Pb in dry and wet seasons respectively, while that of annual was Cr>Fe>Zn>Cu>Pb. The results showed that all of the five elements analyzed have concentrations well above the FEPA, WHO, AWWA, CCME standard limit for effluents discharge into surface. There was an observed seasonal variations in which dry season had a relatively higher heavy metals concentration, but not statistically significant at P≤0.05. This study underscores the need for the government to establish water catchments management agency for the purpose of protecting the basin ecologically and health wise, bearing in mind the socio-economic potentialities the basin has on the populace utilizing it and the nation in general.
The State and Development in Africa
TS Fonchingong
African Journal of International Affairs , 2005,
Abstract: Colonisation obstructed the internal process of state formation and development in Africa and left legacies of authoritarianism, corruption and political instability. Embodied in the post-colonial state and sustained by foreign aid, these colonial legacies constitute the main obstacles to development in postcolonial Africa. The only way to liberate Africa and ensure its progress is a three-stage process involving the repudiation of foreign aid, the restructuring of territorial boundaries in accordance with African realities, and the formation of an African continental government. The African academia should be in the vanguard of African liberation by educating and mobilising the populace.
Between ambivalence and necessity in the Nile Basin: Occlusions on the path towards a basin-wide treaty
TS Bulto
Mizan Law Review , 2008,
Abstract: “Watersheds come in families; nested levels of intimacy. On the grandest scale the hydrologic web is like all humanity. ... The big river is like your nation, a little out of hand. The lake is your cousin. The creek is your sister. The pond is her child. And, for better or worse, in sickness and in health, you are married to your sink.” 1

Tuberculous uveitis
Oluleye TS
Journal of Multidisciplinary Healthcare , 2013, DOI: http://dx.doi.org/10.2147/JMDH.S38752
Abstract: berculous uveitis Review (426) Total Article Views Authors: Oluleye TS Published Date February 2013 Volume 2013:6 Pages 41 - 43 DOI: http://dx.doi.org/10.2147/JMDH.S38752 Received: 03 October 2012 Accepted: 13 November 2012 Published: 19 February 2013 Tunji Sunday Oluleye Retina and Vitreous Unit, Department of Ophthalmology, University College Hospital, Ibadan, Nigeria Abstract: Tuberculous uveitis is an underdiagnosed form of uveitis. Absence of pulmonary signs and symptoms does not rule out the disease. In an era of reduced immunity from human immunodeficiency virus and acquired immunodeficiency syndrome, the disease is becoming more prevalent. This review discusses the common manifestations of tuberculous uveitis, pointing out helpful diagnostic criteria in suspicious cases of uveitis. Physicians need to be aware that ocular manifestations of tuberculosis may be independent of systemic disease.
