The clones were planted in a Randomized Complete Block Design (RCBD) and replicated three times. Analysis of variance showed significant differentiation among studied genotypes. The results revealed that among the evaluated genotypes ILS 708-05 was characterized by highest potential cane yield (105.54 t/ha). BD 1576-14 significantly had highest brix (24.90%) among the tested clones. Genotypes that performed better than the Check ([Standard] B 47419) in terms of cane yield, less flowers and tolerance to smut should be advance to multi-location trials.

The inhibitive effect of Thevetia peruviana on the corrosion behavior of carbon steel in 1 M HCl ... more The inhibitive effect of Thevetia peruviana on the corrosion behavior of carbon steel in 1 M HCl was studied using the weight loss method, polarization, AC electrochemical impedance spectroscopy and electrochemical frequency modulation techniques. The inhibition efficiency was found to depend on the concentration of the extract and the temperature of the medium. Results showed that this extract acts as a mixed-type inhibitor. The charge transfer resistance increases but the double layer capacitance decreases by increasing the extract concentration. It was found that the investigated extract acts via adsorption on the carbon steel surface and obeys the Temkin adsorption isotherm. The effect of temperature on the corrosion rate in the absence and presence of the extract was investigated, some activated, and the adsorption parameters were calculated. The results of the electrochemical methods were in good agreement with the weight loss measurement results.

The composites of conducting polymermagnetic metal nanoparticles are promising candidates based on the fact that the small sized particles enhance their physical properties while the conducting polymer matrix present electrical hostguest interaction to have a new magneto-electric phenomenon to occur at the same time, allowing coupling between magnetic and electric properties for future devices. Among the conducting polymers, polyaniline (PANI) has been of particular interest because of its environmental stability and controllable electrical conductivity and dissipation of electrostatic charges. In this work PANI was used to encapsulate nickel (Ni), cobalt (Co), and chromium (Cr) magnetic nanoparticles in polyvinyl alcohol (PVA) aqueous and film matrix. The solution composites were synthesized from aniline monomer (0.067 g), nickel, cobalt, and chromium chlorides at different concentrations (0.017, 0.025, 0.033, 0.042, and 0.5 g), and PVA (0.1 g), 10 ml

The experimental design was Randomized Complete Block Design (RCBD) arranged factorially in three replications. The treatment consisted of three vetch species and three seeding ratios (25:75, 50:50 and 75:25% finger millet: vetch respectively) and one pure stand of each as a control. The dry matter yield (DMY) of finger millet straw was different (P < 0.05) for the tested treatment combinations and the highest DMY of finger millet straw (5.85 t ha À1) was obtained from T10. The crude protein yield of finger millet straw was also influenced by the main effect and interaction effects of species and seeding ratio (P < 0.05). According to this study, T10 gave the highest (0.50 t ha À1) crude protein yield of finger millet straw. In general, vetch intercropping with finger millet has improved overall dry matter yield and quality of the intercrops. Thus, T10 was found to be the best treatment tested in terms of dry matter yield and quality to be used in a food/feed production strategy in a mixed crop-livestock production system to alleviate food/feed shortages in Bako and similar agro-ecologies.

For many years, technological packages for the control of this weed were proposed and implemented on farmers' fields. A study was conducted in 2012 and 2013 to determine maize/ Jointvetch (Aeschynomenehistrix) and N fertilization effect on Striga infestation and maize yield. The intercropping trial consists of six treatments, four inorganic N fertilizer levels of 0, 60, 90, 120 kg ha-1 , alternate hill and same hill intercropping of A. histrix. The experiment was laid out in a randomized complete block design with three replicates. Alternate hill and same hill intercropping significantly (P < 0.05) reduced Striga infestationwith respect to Striga shoots per m-2 and plot, Strigareation score and enhanced maize grain yield. There was a significant decline in the level of damage by Striga on maize in plots that received 60-120 kg N ha-1. Alternate hill and same hill intercropping had maize grain yield of 3295 kg ha-1 and 2616 kg ha-1 which were significantly higher than those obtained without inorganic N application (306 kg ha-1). Inorganic N application had a significant (P < 0.05) effect on grain yield. Lowest grain yield of 306 kg ha-1 was obtained without inorganic N application, whi ch was significantly (P<0.05) different from those fertilized with inorganic N, that had comparable grain yields. Inorganic N fertilizer rate of 60 kg ha-1 seems to be optimum for maize.

Lowest grain yield of 306 kg ha-1 was obtained without inorganic N application, whi ch was significantly (P<0.05) different from those fertilized with inorganic N, that had comparable grain yields. Inorganic N fertilizer rate of 60 kg ha-1 seems to be optimum for maize.

By using a variety of tools of fractional calculus including the Schauder fixed point theorem and the Banach fixed point theorem, we verify the existence, uniqueness and continuous dependence of solution of weighted neutral problem.

Para evaluar esta problemática del suelo, es necesario conocer algunas de sus propiedades geotécnicas. Generalmente, en las metodologías diseñadas para este fin se emplean valores promedios de las propiedades de los suelos, de la formación geológica o grupo litológico, aspecto que conlleva una gran incertidumbre. Para superar este problema, en la investigación se propone un procedimiento para la estimación espacial y modelación de las principales propiedades del suelo que inciden en la evaluación de su expansividad. El caso de estudio seleccionado comprende la localidad Hermanos Cruz, perteneciente a la Ciudad de Pinar del Río en el occidente de Cuba. La investigación se organizó en las siguientes etapas: evaluación primaria del potencial de expansión de los suelos, modelación de propiedades de los suelos utilizando los métodos geoestadísticos en 3D y, finalmente, representación cartográfica del potencial de expansión de los suelos sobre plataforma SIG a profundidades del subsuelo con importancia en la construcción de las cimentaciones superficiales de las obras ingenieriles. La aplicación de este procedimiento al caso de estudio seleccionado reveló que los suelos del reparto Hermanos Cruz poseen un potencial de expansión bajo a medio y la existencia de sectores aislados con un potencial de expansión medio a alto. Palabras clave: expansividad, geoestadística, propiedades de los suelos arcillosos Evaluation of the potential expansiveness of soils in the Hermanos Cruz neighbourhood, Pinar del Rio, Cuba: a contribution to urban planning ABSTRACT Expansive soils can be categorized as one of the geohazards observed in the urban environment, representing a silent hazard to buildings and infrastructure. To evaluate this problematic soil it is necessary to know some of its geotechnical properties. Generally, the average values of soil properties are used in the methods which characterize the geological formation and the lithological group, which causes a great degree of uncertainty. To overcome this problem, this study proposes a procedure for estimating and modelling the principle soil properties that have an impact on expansive soils. The selected case study is located in the Hermanos Cruz neighbourhood in the city of Pinar del Rio in Cuba. The investigation was organized into the following stages: primary assessment of the potential expansiveness of the soils, modelling of the soil properties utilizing 3D geostatistical methods and finally the cartographic representation of the potential Chinthaka-Ganepola, G.A., et al.
