A rapid method for determination of formaldehyde in paint and indoor air by flow injection spectrophotometry based on the catalytic effects of formaldehyde on the oxidation reaction of methyl orange by potassium bromate in sulfuric acid medium was established. The relationship of the reduced absorbency to the concentration of formaldehyde was good linearity and the maximum absorption peak located at 508 nm. The affecting factors on the strength of absorption including temperature, acidity, dosage, coexisting ions and so on, and the optimal conditions of the reaction in the system were investigated. Calibration graphs were linear for ranges of 0 to 1.0 mg/L and a detection limit of 1.1×10-8 g/mL formaldehyde was achieved. The proposed method was successfully applied to the analyses of paint and indoor air samples, with relative standard deviation of less than 1.8% and the recoveries are 94.6％ to 106.2％for the determination of formaldehyde.

Modelling Process

The process of creating a geological block model as the basis for a further detailed design and planning of mining operations is a very responsible task. Errors made during this initial process are transferred to all other phases of the mining project. Certainly, one of the most important decisions for the modelling process is the choice of the appropriate size of the blocks that form the model itself. The determination of the optimal block size is not a simple process, because it depends on a large number of affecting factors and criteria. This process can be significantly facilitated by the application of multi-criteria analysis methods, which enable establishment of interdependence between the criteria in order to select the optimal solution. This paper presents the possibilities of applying the Analytical Hierarchical Process (AHP) method for selecting the optimal block size for the needs of the coal deposit modelling process and mine planning, as well as the way in which this method can significantly facilitate problem solving, by looking at it from several aspects. The analysis included six criteria and four potential solutions, and the results themselves indicated the advantages and disadvantages of the applied method.

A method for determination of cobalt in water by flow injection spectrophotometry based on the catalytic effects of cobalt on the oxidation reaction of arsenazo III by potassium bichromate in HAc-NaAc buffer solution of pH 4.6 was established. The relationship of the reduced absorbency to the concentration of cobalt was good linearity and the maximum absorption peak located at 550 nm. The affecting factors on the strength of absorption including acidity, dosage, temperature, coexisting ions and so on, and the optimal conditions of the reaction in the system were investigated. Calibration graphs were linear for ranges of 0 to 20 μg/mL and a detection limit of 0.3 μg/mL cobalt was achieved. The proposed method was successfully applied to the analyses of industrial waste water samples, with relative standard deviation of less than 1.5% and the recoveries are 95.1% to 96.8%for the determination of cobalt.

Abstract Background: As increasing the number of organ donations presents a global challenge, Saudi Arabia is no different. Intensivists can play a major role in maximizing the organ donation process and minimize the challenges. The purpose of this study was to investigate Saudi pediatric intensivists’ comfort and importance levels of organ donation competencies.Methods: We conducted a cross-sectional survey whose sampling frame included 100 pediatric intensivists. The pediatrician intensivists were identified through an updated list provided by the Saudi Critical Care Society. We assessed 14 competencies categorized into four domains: the general donation, donation after brain death (DBD), neurological determination of death, and medicolegal, religious, and ethical domains. Then we investigated the association between these competencies and physicians’ characteristics.Results: With a response rate of 76%, we found that 40%–60% of the surveyed pediatric intensivists rated their comfort in 6 out of 14 competencies as high or very high. There was a statistically significant gap in the intensivists’ rating of 10 competencies (i.e., high importance but low comfort levels). Ordinal regression showed that comfort levels with the general donation, neurological determination of death, and medicolegal, religious, and ethical domains were higher in intensivists who were frequently involved with DBD than those who had never been exposed.Conclusions: Pediatric intensivists expressed low comfort levels to organ donation competencies that are essential for maximizing donation rates. Adapting mandatory comprehensive donation education programs and dedicated physician specialists may be beneficial in critical care units aiming to increase donation rates.

The pediatric intensive care community should invest in educational opportunities in the country to boost the low levels of organ donation.
