Appendiceal Knotting: A Rare Complication Causing Intestinal Obstruction in a Child
CS Lukong, BA Jabo, AK Nuhu
Journal of Surgical Technique and Case Report , 2009,
Abstract: Appendicitis is a common cause of acute abdomen in children. Its common complications are; perforation, gangrene and appendix mass. The most dreaded complication is portal pyemia which could be fatal. Appendiceal knotting is a rare complication. No patient with this complication has been reported in literature. We therefore present the management of this rare complication seen as a cause of intestinal obstruction in a child at our centre. KEY WORDS: Appendicitis Complication, Knotting.

A Technique to Avoid the Marginal Artery During Divided Colostomy in Neonates
PM Mshelbwala, EA Ameh, CS Lukong, MA Anumah, BA Jabo
Journal of Surgical Technique and Case Report , 2009,
Abstract: Colostomy is a frequently performed procedure in neonates presenting with anorectal malformation and Hirschsprungs disease. A divided colostomy is more commonly performed but has a definite risk of injury to the marginal artery during the procedure, leading to stoma necrosis. This is a description of a technique which identifies, displaces and preserves the marginal artery during colostomy construction and therefore ensures a safer colostomy in neonates without the danger of necrosis.
Work Done on a Coherently Driven Quantum System  [PDF]
Issofa Nsangou, Lukong Cornelius Fai
Journal of Quantum Information Science (JQIS) , 2015, DOI: 10.4236/jqis.2015.53011
Abstract: We calculate the work done by a Landau-Zener-like dynamical field on two- and three-level quantum system by constructing a quantum power operator. We elaborate a general theory applicable to a wide range of closed-quantum system. We consider the dynamics of the system in the time domain ]-tLZ,tLZ[ (where is the LZ transition time in the sudden limit) where the external pulse changes its sign and its action becomes relevant. The statistical work is evaluated in a period [0,T] where T ≤tLZ. Our results are observed to be in good qualitative agreement with known results.
Dilemmas over individual and state responsibility for violations of international humanitarian law
Mengjo Keneth Lukong
Medjunarodni Problemi , 2004, DOI: 10.2298/medjp0404345m
Abstract: This paper attempts an explanation to some of the complex legal issues surrounding the whole concept of responsibility for violations of international humanitarian law. The arguments here are based on reflections on the draft articles on the responsibility of states for the violations of international humanitarian law adopted by the international law commission as well as opinions of experts on the subject, treaties, conventions international jurisprudence, and internationally recognized principles and customs that govern conduct in armed conflicts so as to limit human suffering particularly of non combatants.
Thermodynamic Properties and Decoherence of a Central Electron Spin of Atom Coupled to an Anti-Ferromagnetic Spin Bath  [PDF]
Martin Tchoffo, Georges Collince Fouokeng, Lukong Cornelius Fai, Mathurin Esouague Ateuafack
Journal of Quantum Information Science (JQIS) , 2013, DOI: 10.4236/jqis.2013.31003
Abstract:

The decoherence of a central electron spin of an atom coupled to an anti-ferromagnetic spin bath in the presence of a time varying B-Field (VBF) is investigated applying the Holstein-Primak off and Bloch transformations approaches. The Boltzmann entropy and the specific heat capacity at a given temperature are obtained and show the correlation of the coupling of the spin bath and the electron spin of the central atom. At low frequencies the coherence of the coupled system is dominated by the magnetic field intensity. At low VBF intensity, there is decrease in entropy and heat capacity at increase external magnetic field that show the decoherence suppression of the central electron spin atom. The crossing observed in the specific heat capacity corresponds to the critical field point Bc of the system which represents the point of transition from the anti-ferromagnetic system to the ferromagnetic one.

Tailoring Quantum Correlations of a Coupled Central Two Qubits Soaked in a Finite Temperature Antiferromagnetic Environment with Frequency Gap  [PDF]
Lukong Cornelius Fai, Ngwa Engelbert Afuoti, Georges Collince Fouokeng, Jules Casimir Ngana Kuetche, Martin Tchoffo
Journal of Quantum Information Science (JQIS) , 2014, DOI: 10.4236/jqis.2014.44019
Abstract: We revisit the quantum features of an anti-ferromagnetic (AF) spin environment at finite temperature with gap in its frequency spectrum, on the dynamics quantum correlations of a coupled central two qubits system with Dzyaloshinskii-Moriya (DM) interaction, prepared in two entangled Bell states. Using entanglement and quantum discord as quantum meters of decoherence, the prepared entangled states are classified as robust or fragile relative to the degree of information leakage to the AF environment. By tailoring the size of the frequency gap, anisotropy field strength and induced field, due to system AF spin environment coupling, size of the AF environment and DM interaction parameter, a decoherence-free sub-space can be accessed for efficient execution of quantum protocols encoded in the entangled states.
COMPARATIVE ANALYSIS ON LARGE HYDROPHOBIC RESIDUES AND SMALL HYDROPHOBIC RESIDUES IN DIFFERENT ORGANISMS
VINOBHA CS,VINOBHA CS
International Journal of Bioinformatics Research , 2011,
Abstract: One of the major tasks carried by biologist today is to understand the nature of proteins. How this largeprotein molecule folds themselves into some form and carryout the prescribed biochemical reactions.Hydrophobic interaction is the dominant force towards this task. To understand this interaction, a simple statisticalanalysis on the contribution of hydrophobic residues was carried out. Large Hydrophobic Residues (LHR) such asPhenylalanine (F), Isoleucine (I), Leucine (L), Methionine (M) and Valine (V) – (FILMV) as well as smallhydrophobic residues (SHR) Glycine (G), Alanine (A), Proline (P), Cysteine (C) and Tryptophan (W) - (GAPCW)were studied in all proteins of given organisms. The organisms include Homo sapiens, Macaca Mullatta, Pantroglodytes, Canis familiaris, Gallus gallus, Mus musculus, Rattus norvegicus, Bos taurus, Drosophilamelonogaster, Monodelphis domestica, Danio rerio, Stronglycentrolus purpuratus, Anopheles gambiae, Apismellifera, Arabidopsis thaliana, Tribolium castaneum, Saccharomyces cerevisae, Schizosaccharomyces pombeand Caenorhabditis elegans. It is observed that the protein prefers to have 27% large hydrophobic residues tomaintain the required hydrophobicity. In animal, particularly in human, it is observed less. It is interesting to notethat small hydrophobic residues balance this lack in number by a factor of 1:3. So is the reason why the length ofthe animal proteins increases. This new finding on the contribution of hydrophobic residues in protein stability willbe discussed in detail
