Abstract: Diploid cotton Gossypium herbaceum has wide adaptability and high degree of resistance to biotic and abiotic stresses.Development of diploid cotton varieties suitable for 40s count yarn will make them more remunerative to diploid cotton growers.In this regard a study on genetic introgression through inter-specific hybridization was initiated using G. barbadense tetraploidcotton to improve fiber strength of G. herbaceum cotton. Pedigree selection from F2 to F11 was practiced. These F11 lines wereevaluated at ARS, Dharwad Farm, during 2009-10 in Augmented Design-II. Observations on fiber traits, seed cotton yield andginning outturn were recorded and analysed using Windostat version 8.5. Seed cotton yield ranged from 801 to 3037 kg/ha with832.38 per cent GCV, 100 per cent heritability and 42.71 per cent genetic advance as per cent mean. Range for ginning outturnwas 20.70 to 42.50 per cent with 25 per cent heritability, 13.93 per cent GCV and 18.84 per cent genetic advance as per centmean. Recorded fibre strength was in the range of 15.42 to 20.67 g/tex with variability parameters like 10.36 per cent GCV, 86per cent heritability and 5.98 per cent genetic advance as per cent mean. The value for 2.5 % span length ranged from 23.87 to29.52 mm with 9.38 per cent GCV, 72 per cent heritability and 5.24 per cent genetic advance as per cent mean. The sevenselections PSCCOL-15, 30, 31, 32, 36, 53 and 62 recorded significantly higher seed cotton yield than DLSa-17 (1124 kg/ha) andsuperior fiber traits than DDhC-11 (17.10 g/tex, 24.00 mm) commercial diploid cotton varieties. These selections recorded 49 to125 per cent yield increase over DLSa-17. It indicates the possibility of improvement in both seed cotton yield and fibre qualitytraits of G. herbaceum cotton through inter-specific hybridization using tetraploid cotton G. barbadense as a donor parent.

Indian Phytopathology , 2011,
Abstract: Twenty four leaf spot and blight infected samples of sunflower were collected from Rahuri, Parbhani, Latur and Pune districts of Maharashtra. Several fungal species were isolated from the infected samples, which were purified by single spore or hypha I tip methods. These include Alternaria alternata (MTCC 7202), Alternaria dianthicola (MTCC 7203), Alternaria helianthi, A. longipes (MTCC 7150), Bipolaris australiensis (Syn. Dreschslera australiensis, MTCC 7215) and Phoma helianthi. The pathogenicity of the fungi was tested on sunflower individually. This is the first report of association of A. dianthicola, A. longipes and B. australiensis with leaf spot of sunflower. The ribosomal RNA genes of

Journal Tunisien d'ORL et de Chirurgie Cervico-Faciale , 2007,
Abstract: Les myxomes des maxillaires sont des tumeurs bénignes rares dont la pathogénie reste encore controversée. Leur indolence et la pauvreté des manifestations qui les accompagnent rendent leur diagnostic souvent tardif et leur prise en charge difficile. Nous présentons un cas de myxome du maxillaire chez un nourrisson agé de 12 mois suivi d\'une revue de la littérature permettant de synthétiser les données cliniques ainsi que la stratégie thérapeutique à adopter. Maxillary myxoma are rare benign tumours whose pathogenesis remains extremely discussed. The poor clinical picture and the absence of pain makes the diagnosis difficult. We report a pediatric case of maxillary myxoma of a 12- monthold infant and review the clinical features, radiographic evaluation and the appropriate treatment

Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.515215

In this paper, I have provided a brief introduction on M?bius transformation and explored some basic properties of this kind of transformation. For instance, M?bius transformation is classified according to the invariant points. Moreover, we can see that M?bius transformation is hyperbolic isometries that form a group action PSL (2, R) on the upper half plane model.

Petroleum Potentials of the Nigerian Benue Trough and Anambra Basin: A Regional Synthesis  [PDF]

Natural Resources (NR) , 2014, DOI: 10.4236/nr.2014.51005

A review on the geology and petroleum potentials of the Nigerian Benue Trough and Anambra Basin is done to identify potential petroleum systems in the basins. The tectonic, stratigraphic and organic geochemical evaluations of these basins suggest the similarity with the contiguous basins of Chad and Niger Republics and Sudan, where commercial oil discovery have been made. At least two potential petroleum systems may be presented in the basins: the Lower Cretaceous petroleum system likely capable of both oil and gas generation and the Upper Cretaceous petroleum system that could be mainly gas-generating. These systems are closely correlative in temporal disposition, structures, source and reservoir rocks and perhaps generation mechanism to what obtains in the Muglad Basin of Sudan and Termit Basin of Niger and Chad Republics. They are very effective in planning future exploration campaigns in the basins.

Abstract: Both Hybrid Electric Vehicles (HEVs) and Electric Vehicles (EVs) need a traction motor and a power in-verter to drive the traction motor. The requirements for the power inverter include high peak power, opti-mum consumption of energy, low output harmonics and inexpensive circuit. In this paper, a new structure of multilevel inverter with reduced number of switches is proposed for electric vehicle applications. It consists of an H-bridge and an inverter in each phase which produces multilevel voltage by switching the dc voltage sources in series. As the number of switches are reduced, both conduction and switching losses will be de-creased, which leads to increase the efficiency of converter. The size and power consumption of driving cir-cuits are also reduced. The proposed three phase inverter can produces more number of voltage levels in the same number of the voltage source and reduced number of switches compared to the conventional inverters. This structure minimizes the total harmonic distortion (THD) of the output voltage waveforms. The structure of proposed multilevel inverter, modulation method, switching losses, THD calculation and simulation re-sults with PSCAD/EMTDC software are shown in this paper.

Journal of Biosciences and Medicines (JBM) , 2014, DOI: 10.4236/jbm.2014.21008

Pot experiment was conducted at the Botanical Garden of the Department of Biological Science, Usmanu Danfodiyo University, Sokoto Nigeria, during the 2013 dry season. The main objective of this research was to determine the effect of water stress and variety on productivity of rice (Oryza sativa) at Sokoto. The treatment consisted of water stress at three growth stages (Tillering, flowering, Grain filling) and unstress (control) and three rice varieties (FARO 44, NERICA 2 and FARO 15) laid out in a Completely Randomised Design (CRD) replicated three times. The result indicated that water stress significantly (P < 0.05) resulted to decreased in plant height, number of leaves per plant, total biomass, harvest index and grain yield. The results indicated significant (P < 0.05) differences among genotypes. Faro 44 differed significant from in plant height, number of leaves per plant, total biomass, harvest index and grain yield. FARO 44 differed significantly from NERICA 2 and FARO 15 at all the parameters under study. Water is very vital as far as rice production is concern should be applied at every stage of rice production. FARO 44 is recommended for the area for higher yield.

Open Journal of Physical Chemistry (OJPC) , 2014, DOI: 10.4236/ojpc.2014.44017
Abstract: Equilibrium adsorption studies for detoxification of Congo Red (CR) dye from single component model wastewater by powdered watermelon rinds and neem leaves adsorbents were carried out with the view to test the applicability of the adsorption process to Langmuir, Freundlich, Temkin, Dubinin-Radushkevich and Harkins-Jura isotherm models. The values of correlation coefficient, R2 (0.9359 - 0.9998), showed that all the experimental data fitted the linear plots of the tested isotherm models. Dubinin-Radushkevich’s monolayer maximum adsorption capacity qD (20.72 - 26.06 mg/g) is better than Langmuir’s qm (18.62 - 24.75 mg/g) for both adsorbents with the capacities higher for adsorption on watermelon rind than on neem leaves. Values of Langmuir separation factor (RL) suggest unfavourable adsorption processes (i.e. chemisorption) of the dye on both the adsorbents, while Freundlich constant (nF) indicates unfavourable process only for CR adsorption onto neem leaves. The Dubinin-Radushkevich’s mean free energy of adsorption, E
Quality of Some Nigerian Coals as Blending Stock in Metallurgical Coke Production  [PDF]
M. B. Nasirudeen, A. Jauro
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2011, DOI: 10.4236/jmmce.2011.101007
Abstract: Two Nigerian coals, Lafia-Obi and Chikila were blended in the mass ratio of 70:30 with imported American and Polish coking coals. Proximate analysis, free swelling index, Ruhr dilatometer and Gieseler plastometer were used in assessing the coking qualities of both the single coals and the blends. The results show that the blends are lower in moisture and ash contents; higher in volatile matter and fixed carbon than the single Nigerian coals. The rheological parameters revealed superiority in thermo-plastic properties of the blends over the unblended local coals. Lafia-Obi/Foreign coals blends possess lower ash and better rheological properties compared to Chikila/Foreign coal composites which have high ash and poor rheological properties. These together suggest that amongst the two Nigerian coals, Lafia-Obi is superior for blending with the foreign ones in metallurgical coke production.
