The effect of some acids, anions and auxiliary complexing agents on the extraction of Cadmium (II) from aqueous solutions buffered to pH 7.5 using a chloroform solution of the Schiff base ligand 4,4´-(1E,1E´)-1,1´-(ethane-1,2-diylbis(azan-1-yl-1ylidene))bis(5-methyl-2-phenyl-2,3-dihydro-1H-pyrazol-3-ol) (H2BuEtP) alone and in the presence of 1-(3-hydroxy-5-methyl-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl) butan-1-one (HBuP) after an equilibration time of sixty minutes was investigated. Working concentration of Cd(II) was 50mgL-1, while a range from 0.001M-3.0M was used for acid and 0.001M-1.0M for anions and auxiliary complexing agents. Extraction raffinates were analysed for Cd(II) using Flame Atomic Absorption spectrophotometry and Distribution Ratios. Percentage Extractions (%E) were calculated by difference of Cd(II) concentrations before and after equilibration. The mixed ligands H2BuEtP/HBuP organic phase was a better extractant for Cadmium than H2BuEtP alone but the difference was not significant for all acids, Cl-, Oxalate and Tartrate. The results indicated that at lower concentrations of the acids, anions and auxiliary complexing agents, a releasing effect occurred with improved extraction of Cadmium > 90% in most cases and at high concentrations there was reduced percentage extraction due to masking of Cadmium from formation of stable salts of Cadmium. Comparing results with other those of other metals studied under same conditions showed that multi-metal extraction with the ligand (H2BuEtP) is possible. H3PO4, H2SO4, HCl, PO43-, EDTA and Oxalate all showed theoretical potentials for separating Cadmium from other studied metals with Separation Factors βxy = Dx/Dy close to and above 104.

Globally, health information systems and technologies are being used increasingly and are seen as a way to increase the efficiency and quality of patient care. One of the factors blocking the use of electronic healthcare system from widespread acceptance as experienced in the manual method is the concern about patients' data confidentiality. This paper is set to discuss and appraise the adoption of electronic style in the provision and management of hospital services for efficiency, accuracy, and timely delivery of services in order to enhance the data confidentiality. Data collected from questionnaire were analysed and evaluated based on two identified significant aspects: the problems of either adopting the electronic healthcare or manual system of keeping patient information and the efficiency, problems, and barriers of adopting the electronic healthcare style in hospitals. It is observed that the adoption of electronic style will improve interactivity in all areas of specialization in hospital management.

In previous experimental study with three-way-reversal and juggling sequence rotation algorithms, using 20,000,000 elements for type LONG in Java, the average execution times have been shown to be 49.66761ms and 246.4394ms, respectively. These results have revealed appreciable low performance in the juggling algorithm despite its proven optimality. However, the juggling algorithm has also exhibited efficiency with some offset ranges. Due to this pattern of the juggling algorithm, the current study is focused on investigating source of the inefficiency on the average performance. Samples were extracted from the previous experimental data, presented differently and analyzed both graphically and in tabular form. Greatest common divisor values from the data that equal offsets were used. As emanating from the previous study, the Java language used for the rotation was to simulate ordering of tasks for safety and efficiency in the context of real-time task scheduling. Outcome of the investigation shows that juggling rotation performance competes favorably with three-way-reversal rotation (and even better in few cases) for certain offsets, but poorly with the rests. This study identifies the poorest performances around offsets in the neighborhood of square root of the sequence size. From the outcome, the study therefore strongly advises application developers (especially for real-time systems) to be mindful of where and how to in using juggling rotation.
