The study assessed the factors influencing the utilization of Maternal Healthcare Centers (MHC) for delivery among pregnant women attending ante-natal care in Ikenne, Ogun state, Nigeria. A total of 96 respondents were selected from 5 MHC for the study using the multistage sampling procedure. All the women were monitored till delivery. Furthermore, 48 (50%) of the respondents were randomly chosen and exposed to motivational telephone calls for 6 weeks preceding delivery dates. Structured questionnaire was used to gather data which were analyzed using descriptive statistics and logistic regression. All analyses were measured at p≤0.05 level of significance. Results showed that most of the women were between 30 and 34 years old, had up to secondary education, recorded parity of 1-2 while timing of first visit was between 20 and 24 weeks of gestation and number of Ante-natal visits were ≥ 4. Monthly income was generally less than N16,000 (~$80). Some 52% of the women gave fair rating for the services received from the healthcare workers and 58% used the MHC for delivery. However, 84% of those who received telephone calls used MHC for delivery while 59% of those who did not received telephone calls used MHC for delivery.

Des siècles après leur présence involontaire sur le sol américain en qualité d’esclaves, les Noirs ont finalement reçu un espoir : le Président Abraham Lincoln a imposé l’émancipation des Noirs au peuple américain, au prix d’une guerre civil qui a failli faire éclater la fédération. Avec tant de détermination et d’efforts, il apparait inimaginable que l’idée derrière une telle promesse de libération soit simplement truquée, et pleine d’hypocrisie. Les Noirs Américains se rendront donc à l’évidence que leur situation étaient plutôt pire, passant d’une étape de domination à celle de persécution.

Cloud computing is a global established system. Quantum computing is hypothetical model which is still in tentative analysis. Cloud system has some weakness in security, processing, backup and vicinity. Somehow quantum computing illustrates some revolutionary solution to overcome cloud weakness. Most researchers are optimistic in quantum computing that it will improve cloud system. It is not easy to combine these two different systems along. We will show two quantum approaches; quantum cryptography and blind quantum computing to secure cloud computing. Quantum cryptography will secure the user data transmission and communication through cloud form hackers. And blind computing will secure the instant eavesdropping or accessing of data processing in cloud from any vicious cloud provider or third party. This paper’s major target is to show advantages and disadvantages of quantum computing in the viewpoint to integrate it with cloud system. Also review some current improvement of quantum computing and computer.

This paper studies the global exponential stability of impulsive functional differential system with the effect of delay at the time of impulses by using Lyapunov functions and Razumikhin technique. This result extends some results existing in the literature. The obtained result also shows that the derivative of Lyapunov function may not be negative even then impulses can make the system globally exponentially stabilized.

The purpose of this paper is to investigate the extraction of fresh water from humid air in Saudi Arabia by direct solar absorption system using aqueous ammonia 0.45 mass fractions (ammonia–water). In the system, ammonia is boiled out of the water then condensed in an air cooled condenser. The refrigerant is then expanded and evaporates in the evaporator exists inside a tunnel where humid air flows, and therefore the temperature of humid air is reduced beyond its dew point temperature so a process of water separation from humid air starts. To analyze the performance of the system, first a comprehensive mathematical model describing the entire processes accomplished within the major components in the cycle is introduced based on heat and mass conservation balancing considering steady flow processes. The results of calculations are to find out the actual real sizes of all involved major components within the system based on simulation analyzing. The amount of the extracted fresh water from humid air is determined for certain operation conditions in the Kingdome of Saudi Arabia, it was found for real atmospheric conditions to be and the efficiency of the system is 1.369. Furthermore, analyzing the impact of prevailing atmospheric parameters in order to determine their effects on the performance of the system. Thus, and furthermore the investigation involved assessing the influence of different operation conditions such initial flow rate of the working fluid(Ammonia-water), humid air, solar radiation and ambient temperature on the system performance characteristics (system efficiencies, evaporation rate and water productivity).

Data clustering is a well known technique for fuzzy model identification or fuzzy modelling for apprehending the system behavior in the form of fuzzy if-then rules based on experimental data. Fuzzy c- Means (FCM) clustering and subtractive clustering (SC) are efficient techniques for fuzzy rule extraction in fuzzy modeling of Adaptive Neuro-fuzzy Inference System (ANFIS). In this paper we have employed a novel technique to build the rule base of ANFIS based on the kernel based variants of these two clustering techniques which have shown better clustering accuracy. In kernel based clustering approach, the kernel functions are used to calculate the distance measure between the data points during clustering which enables to map the data to a higher dimensional space. This generalization makes data set more distinctly separable which results in more accurate cluster centers and therefore a more precise rule base for the ANFIS can be constructed which increases the prediction performance of the system. The performance analysis of ANFIS models built using kernel based FCM and kernel based SC has been done on three business prediction problems viz. sales forecasting, stock price prediction and qualitative bankruptcy prediction. A performance comparison with the ANFIS models based on conventional SC and FCM clustering for each of these forecasting problems has been provided and discussed.

This paper presents a method of evaluating the effect of aggregate angularity on hot mix asphalt (HMA) properties and its relationship to the Permanent Deformation resistance. The research concluded that aggregate particle angularity had a significant effect on the Permanent Deformation performance, and also that with an increase in coarse aggregate angularity there was an increase in the resistance of mixes to Permanent Deformation. A comparison between the measured data and predictive data of permanent deformation predictive models showed the limits of existing prediction models. The numerical analysis described the permanent deformation zones and concluded that angularity has an effect of the onset of these zones. Prediction of permanent deformation help road agencies and by extension economists and engineers determine the best approach for maintenance, rehabilitation, and new construction works of the road infrastructure.

Background:The interpretation of cardiopulmonary fitness values is based on previously published standard reference values. In other situations, this may cause considerable inaccuracies since cardiorespiratory fitness in a specific population is determined by physical activity habits, geographic living area, body composition, genetics, and other factors, thus, reference values may differ significantly among various populations. The objective of this study was to determine cardiorespiratory values measured as maximal oxygen uptake for young Malawian adults and compare these values with the reference values established for other foreign populations. Methods: This was a cross sectional study involving 133 (62 males and 71 females) apparently healthy young adults aged from 20 to 29 years randomly selected from the Malawian population. Participants performed the Rockport submaximal treadmill exercise test. Measures of body weight, post-exercise heart rate and time to walk one mile were obtained and used to predict VO2max as a measure of cardiorespiratory fitness.Results: MeanVO2max was53.9±12.5 mL.kg-1.min-1 for males and38.8±12.0for females indicating excellent cardiorespiratory fitness for males and good cardiorespiratory fitness for females according to the cooper institute data published by the American College of Sports Medicine (ACSM). Conclusion:Cardiorespiratory fitness measured as VO2max for apparently healthy young Malawian adults have been provided and appear to be within similar ranges as those of some other foreign populations.

According to Planck Mission, the observable universe contains 26.8% dark matter, 68.3% dark energy (for a total of 95.1%) and 4.9% ordinary matter. By calibrating or fine-tuning a speculative equation of matter composition, the equation confirms observable consequences of our theoretical insights, as it solves for roots corresponding to 4.915% ordinary matter, 26.785% dark matter, and 68.300% dark energy, thus achieving nearly 100% overlapping with the Planck Mission Statement. Regarding the past, the equation also confirmed some of NASA Science Astrophysics statements.

There is general lack of scientific consensus on the trend and distribution of annual and seasonal rainfall and temperature in Uganda. This study used both observational and AgMerra rainfall and temperature data for the period 1980-2010 to characterize the trend and variability in seasonal and annual rainfall, maximum and minimum temperatures across 12 different rainfall homogenous zones (K, H, ME, L, J, F, MW, D, E, A1, A2,and I) of Uganda. Trends analysis was done using regression method, while coefficient of variation and ANOVA techniques were used to analyze variability. The results show statistically significant increasing trends (P ≤ 0.05) in annual rainfall amount in zone A1 and a declining trend for zone K (P<0.05). Zones ME and H did not show any significant seasonal trend; while MAM rainfall increased for Zones A1 and F, and declined for J and K. In zone E, the SON rainfall linearly increased with time. The seasonal rainfall amount change was only significantly reflected in the annual rainfall amount of zone A1 and K. The annual rainfall amount increased significantly for A1 and declined for Zone K; respectively.The CV of all the studied rainfall zones showed significant trend over the years (P<0.05). It increased for A1, MW, H, L and I zones, declined for zone D and followed a quadratic trend with a maximum for F, K and ME. Seasonal Tmax and Tmin increased linearly for both seasons for I and D. For A1 and L only Tmax for SON did not show significant variation (P<0.05). For zone L, the MAM Tmin significantly increased gradually for both seasons; while for zone E, Tmax increased only for MAM.The annual Tmax and Tmin increased linearly with time for zone A1, A2, I and L. For zone K, E and F, only Tmax increased linearly with time; while for zone D only Tmin had significantly increased with time.
