Intercropping Sunflower with Soyabeans Enhances Total Crop Productivity

There is a need to develop sustainable and productive cropping systems for edible vegetable oilseeds in tropical Africa. Field trials were conducted during the late cropping season (July–Nov.) of 2001 and 2002 to determine the grain yields, and other yield attributes of sunflower and soyabeans and their productivity under monocropping and intercropping. Three sunflower (Helianthus annuus L.) varieties (a local adapted var. Funtua and two exotic varieties Isaanka and Record from Argentina) and five improved, high yielding soyabean (Glycine max (L.) Merrill) varieties: TGx 1448-2E (late), TGx 1440-1E (late), TGx 1019-2EB (medium), TGx 1740-2F (early) and TGx 1485-1D (early maturing) were used. Funtua had significantly greater head weight and diameter, achene number and weight per head than Isaanka and Record during the dry and relatively hot cropping season of 2001. Cropping system significantly reduced soyabean grain yield in intercropping, relative to monocropping, except when soyabean was intercropped with Isaanka in 2001 and Record in 2002. All yield attributes of both crops exhibited significant positive relationship with grain yields, except height to the lowest pod of soyabean. TGx 1448-2E and TGx 1440-1E intercropped with Isaanka and Record had average grain yield of 1043 and 1081 kg ha–1 and land equivalent ratios (LER) of 1.47 and 1.58, respectively. It is recommended that intercropped combination of TGx 1448-2E/Isaanka and TGx 1440-1E/Record be used to improve yields of vegetable oilseeds

Vibration isolation technology: Sensitivity of selected classes of space experiments to residual accelerations

Progress performed on each task is described. Order of magnitude analyses related to liquid zone sensitivity and thermo-capillary flow sensitivity are covered. Progress with numerical models of the sensitivity of isothermal liquid zones is described. Progress towards a numerical model of coupled buoyancy-driven and thermo-capillary convection experiments is also described. Interaction with NASA personnel is covered. Results to date are summarized and they are discussed in terms of the predicted space station acceleration environment. Work planned for the second year is also discussed

COMBATING INFANT MORTALITY IN IBADAN NORTH LOCAL GOVERNMENT AREA, SOUTHWEST, NIGERIA: NEED FOR SUSTAINABLE DEVELOPMENT

Improve sanitation and health delivery has become an important issue because of it significant implication of quality of life in the society. This paper examines the effect of poor sanitation on infant mortality and effort of both government and individual at combating the menace. Demographic records of the Ibadan North LGA from 2006 to 2010 and perceptions of the people were obtained from Focused Group Discussions, with mothers of between 15 and 49 years at 6 purposively selected residential areas. Analysis of the demographic records shows that the study area, whose average total population was 306,795 as at 2006 national census recorded about 1431 infant deaths. The study indicates that poor sanitation attitude of the residents of the LGA were the reason of high infant mortality. The study therefore concludes that infant mortality can be reduced to the barest minimum if good sanitation is mandated for each household by the relevant local authorities

ENVIRONMENTAL FACTORS AFFECTING INFANT MORTALITY IN IBADAN NORTH LOCAL GOVERNMENT AREA OF NIGERIA

The Local government area (LGA) in Nigeria is the third level of governance and closest to the rural and mostly poor population, with relatively higher records of infant mortality than the urban population. objective of this study is to examine the effect of living and environmental condition on infant mortality in a typical LGA Nigeria, as a case study of the Ibadan North LGA from 2006 to 2010 and perceptions of the people were obtained from Focused Group Discussions (FGDs) with mothers of between 15 and 49 years at 6 purposively selected residential areas. Analysis of the demographic records shows that the local government, whose average total population was 306,795 as at 1431 infant deaths. The number of infant deat variance based on differences in certain housing/environmental characteristics of selected districts, especially sanitation and waste management concerns (r <0.05). The study indicates that inadequate toilet facilities and poor was were the bane of high infant mortality there. The that infant mortality can be reduced to the barest minimum if good toilet facilities are mandated for each household by the rele and good waste management approach is adopte

Spatio-Temporal Factors and Dynamics of Population Growth in Ondo State Nigeria (1970-2010)

Everyone is aware of space and place, of change over time and since everything exists in space and time, population is not an exception. This paper examines the influences of time on population growth and space. The study adopts both descriptive and quantitative statics and relied on secondary data source as a major means of data collection. The findings reveal that there is positive relationship between population growth and time and population density varies from area to area within the state. The practical implication of this study is that it provides an answer to whether population varies over time and space. Over the years Ondo state has witnessed increase in population. The implication of this increase in population in relation to space is overpopulation resulting to congestion in areas that are densely populated

Improvement of Power Delivery Efficiency of 11KV Power Line using Power Capacitor Placement

Optimal capacitor placement in the distribution network is the most popular technique adopted for the control of power loss and enhancement of Volts Ampere Reactive for effective power delivery. This study, therefore, discusses improvement of distribution efficiency of 11kV power lines through placement of capacitor banks in the network. Power flow in the network, Ado-Ekiti 11kV lines, was carried out using Newton-Rapson iteration method available in MATLAB while the analysis of the network was actualized using the conventional load flow equation modeling. From the analysis of the network, voltage deviation falls within the range of -5.9 to -180.5% which is completely outside the permissible range of ±5%. Voltage drop on the feeders is within the range (1.2 – 1.9) kV before and (0.2 – 0.7) kV after the reactive power of the network was compensated
