A high-performance liquid chromatography method was developed for the estimation of ferulic acid from asafoetida and a polyherbal preparation. The separation was carried out on HiQSil ODS C-18 column with a mobile phase of acetonitrile: 10% acetic acid (20:80 v/v). The developed method was validated as per International Conference of Harmonization guidelines for various parameters such as accur...

Let C be a category with finite colimits, and let (E ,M) be a factorisation system on C with M stable under pushouts. Writing C;M for the symmetric monoidal category with morphisms cospans of the form c → m ←, where c ∈ C and m ∈ M, we give method for constructing a category from a symmetric lax monoidal functor F : (C;M,+) → (Set,×). A morphism in this category, termed a decorated corelation, ...

We study some problems of the parameter inference which are in connection with wide sense stationary long memory processes. Here we present the asymptotic behaviour of the corelation matrix and the limit distributions of the LSE for the regression coefficients in some types of linear models with singular Gaussian and non-Gaussian errors.

In the last decade 3D and live 3D ultrasound or the so called 4D (3D/4D) in examination of the fetal heart evolved very rapidly with the development of the new technique called Spatiotemporal Image Corelation - STIC, which enables the aquisition of a volume data concomitent with the beating heart. It appears that 3D/4D ultrasound in fetal echocardiography may make an important contribution to t...

According to the Van Cittert-Zernike theorem, the intensity distribution of a spatially incoherent source and the mutual coherence function of the light impinging on two wave sensors are related. It is the comparable relationship using a single mobile sensor moving at a certain velocity relative to the source that is calculated in this paper. The auto-corelation function of the electric field a...

Introductory: Ambiental air in town of Kakanj, stressed by polutants of mostly industrial origin, has become a major reason for increased use of medical care by school children and youth. The goal: The goal of this work is to examine corelation between ambiental concentrations of sulphurdioxid (SO2), suspended particles and nitrogenoxides (NOx), and of number of visits by schoo l children and y...

The paper presents the history of the Middle Hungarian administrative system. This administrative system is operating under the current government regulation and the administration is depicted as an information security element. The paper describes the operation of the administrative order of today's challenges. The electronic administration is a result due to the increasing number of enterpris...
