Original scientific paper This paper presents designing of spherical tank using combination of analytical procedure with FEM analysis and experimental testing in order to minimize design time and verify design strength. Analytical procedure for calculation of the tank strength in the initial stages of design process is briefly presented. Based on analytical results, tank is dimensioned and FEM ...

As a means of correcting for many potential interferences, polychromatic analysis offers an effective alternative to either sample pretreatment or separate blank determinations. Because of the differing spectral characteristics of each interfering species, and the nature of these interferences (static vs. kinetic), the application of polychromatic analysis must be optimized for each analytical ...

Polymorphic short tandem repeat (STR) analysis after polymerase chain reaction amplification is presently the most important analytical method of forensic DNA laboratory. Beside the forensic-purpose application, STR analysis is also necessary for chimerism testing after bone marrow or allogeneic stem cell transplantation. To increase success rate of the treatment and avoid adverse effect of the...

Electroanalytical methods are chosen for the sensitive analysis of pharmaceutically active compounds in their dosage forms and biological samples. Electroanalytical method validation is the process used to confirm that the determination procedure employed for a specific test is suitable for its intended use like other analytical methods. Results from electroanalytical method validation can be u...

The aim of this paper is to define the architecture of the information analysis towards a proposal of methodology on systematic information analysis. First, the author shows the dimensions that state the architecture of information management. Second, the work explores the concept of indicator, as the measurement of the relation between data, and presents the results of a theoretical study of t...

A relatively simple and rapid procedure for the measurement of free ammonium and the amides in plant extracts is described. The method was developed by combining a cation-exchange method for blood ammonia with a differential acid-hydrolysis procedure for asparagine and glutamine amide-nitrogen. The recovery of standard samples (100-400 mug of ammonium- or amide-nitrogen) of free ammonium, aspar...

Honey and propolis are rich in phenolic compounds, which act as natural antioxidants, and are becoming increasingly popular because of their potential role in contributing to human health. These compounds can also be used as indicators in studies into the floral and geographical origin of the honey and propolis themselves. We present here an overview of current analytical methods for measuring ...

A procedure is introduced that can mitigate the deleterious effect of low-frequency noise [Formula: see text] often termed drift [Formula: see text] on the precision of an analytical experiment. This procedure offers several performance benefits over traditional designs based on the periodic measurement of standards to diagnose and correct for variation in instrument response. Using repeated me...

This paper discusses an improved method for solving multiple objective optimal control (MOOC) problems, and efficiently obtaining the set of Pareto optimal solutions. A general MOOC procedure has been introduced in Logist et al. [2007], to derive optimal generic temperature profiles for a steady-state tubular plug flow reactor. This procedure is based on a weighted sum of the different costs, a...

We confirmed that the alkaline methanolysis procedure of Blanckaert (Biochem. J. 185: 115-128, 1980) converts the sugar conjugates of bilirubin (Bc) into their corresponding methyl and dimethyl esters, which can be extracted into chloroform along with underivatized unconjugated bilirubin (Bu). By this procedure, we accounted for Bu nearly quantitatively, but only 76-83% of total Bc. By pretreat...
