Novel Riboflavin-Inspired Conjugated Bio-Organic Semiconductors
Flavins are known to be extremely versatile, thus enabling routes to innumerable modifications in order to obtain desired properties. Thus, in the present paper, the group of bio-inspired conjugated materials based on the ...
Potential Ecological Risk and Human Health Risk Assessment of Heavy Metal Pollution in Industrial Affected Soils by Coal Mining and Metallurgy in Ostrava, Czech Republic
The purpose of this detailed research was to determine the actual status of heavy metal pollution of soils and an assessment of heavy metal pollution in a highly industrialized city, Ostrava, with a history of long-term ...
Effects of the Lactation Period, Breed and Feed on Amino Acids Profile of mare’s Milk
(HACCP Consulting, 2020-07-28)
The effects of the lactation period, breed, and feed on amino acids profile of mare's milk were investigated. The feed contained two major essential amino acids (EAAs) leucine (7.31-10.3 g. kg-1) and arginine (6.37-9.59 ...

(HACCP Consulting, 2018-03-21)
The article focuses on influence of food and length of lactation period on minerals occurring in mare´s milk
Transesterification of Lactic Acid Oligomers with Ethanol, a Way to Anhydrous Ethyl Lactate: A Kinetic Study
A new method for the preparation of anhydrous ethyl ester of lactic acid was studied. The selected method is based on catalytic transesterification of lactic acid oligomers, which were prepared for this purpose by autocatalytic ...
Sequences of Groups, Hypergroups and Automata of Linear Ordinary Differential Operators
The main objective of our paper is to focus on the study of sequences (finite or countable) of groups and hypergroups of linear differential operators of decreasing orders. By using a suitable ordering or preordering of ...
On Minimisation of Earthing System Touch Voltages
Finding cost efficient earthing system design with acceptable level of safety might be quite tedious work. Thus, many earthing system engineers try to find the most suitable design either by employing only their best ...
Analysis of IEC 61850-9-2LE Measured Values Using a Neural Network
Process bus communication has an important role to digitalize substations. The IEC 61850-9-2 standard specifies the requirements to transmit digital data over Ethernet networks. The paper analyses the impact of IEC 61850-9-2LE ...
Two-Terminal Algorithm Analysis for Unsymmetrical Fault Location on 110 kV Lines
This work analyses a two-terminal algorithm designed to locate unsymmetrical faults on 110 kV power transmission lines. The algorithm processes synchronized voltage and current data obtained from both ends of the protected ...
A Physical Calibrator for Partial Discharge Meters
This article offers an alternative method of calibrating partial discharge meters for research and teaching purposes. Most current modern calibrators are implemented as precise voltage pulse sources with a coupling capacitor. ...
