Cereals and by-products of its processing are known to be applied for lactic acid bacteria fermentation. Wheat grains containing starch, protein and a lot of growth factors seem to be the rich nutrient media for some types of microbes. On the other hand, the niglible number of lactobacilli can produce amylases and proteinases (for native gluten decomposition), so at least the partial hydrolysis of substances mentioned is needed. The complex processing of wheat flour with amylases and proteases was shown to increas...

This paper presents the possibility of using landscape metrics in the process of modeling vulnerability analysis of landscape qualities that should be protected when considering spatial decisions about its future land use. Modeling was carried out on the lower part of Krka River basin, in the Mediterranean part of Croatia. This area is under protection as a significant landscape according to the Croatian Nature Protection Act and it was chosen due to heavy developmental pressures that have resulted and still threa...

Fodder yeasts are widely used in animal feeding as a source of protein with high amount of B vitamins. While plant protein is very poor in such amino acids like lysine, methionine, tryptophan, single cell protein contents all complex of essential amino acids. Studies have shown advantages and possibilities of using single cell protein in complex with plant base for animal feeding. Sunflower is being one of the most cultivated agriculture in Russian Federation. Deproteinized sunflower meal is a secondary product of...

This paper describes the optimized algorithm for searching Hamiltonian path in graph. Formerly a similar algorithm was developed for the finding of the optimized path in terrain for finding of the precise positioning of Global Navigation Satellite Systems (GNSS) via Real Time Kinematics (RTK) method. The aim of this method is to achieve quality GNSS observation on all the points in question, so that the total length of the path within all these points can be minimized. There are nodes of two types in the graph: 1)...

Erythromycin (E), a hydrophobic macrolide antibiotic, is prescribed for the treatment of acute bacterial infections, such as respiratory, urine, skin, and mouth infections. The main disadvantage of ER is its poor water solubility (2 mg/mL) that limits both formulation using hydrophilic bases and skin permeability. Cyclodextrins (CDs) are biocompatible cyclic oligomers of glucose, with a hydrophobic core and a hydrophilic exterior. CDs are used to improve the bioavailability of drugs by increasing their solubility ...

The coal processing industry uses a various technology for the process control. Various devices and control systems there can be implemented. With the support of automation, the production of final product can be more effective. Modern control system requires an advanced control algorithm on a several control levels (i.e. stabilization, optimization). The paper focuses to the process of coal combustion and coal gasification. Primarily two processes are examined i.e. underground coal gasification (UCG) and coking. ...

Proposed methods of thermodynamic description, modeling and calculation for different physico-chemical processes running in various natural and technological systems, represents each of them as a solution (solid, liquid, overcooled) of all its components, which it?s composed, - i.e. with provision of all potentially possible chemical transformations capable to take place in system. Development of the approach includes the correct account of heterogeneous equilibrium of type: the system ? gas environment (atmospher...

Optimization of the measurements is an important theme nowadays of the geodesy and especially engineering geodesy. The optimization can be categorized into orders, from the zero to the third order. The zero order design is the coordinate system selection, the first order is the configuration optimization, the second order is the optimization of the number of the repetitions, the third order is the improvement of the existing network by adding point and/or observations. In the engineering surveying the second order...

The purpose of this article is to describe the modern methods of making models of quarry using the latest technologies such as laser scanning, land and air photogrammetry using Unmanned Aerial Vehicles (UAV) and their subsequent use in the planning of technological processes in the quarry. The first part of the article is dedicated to the creation of models with a focus on data collection and processing, compatibility of each format, the very creation of the model as well as the possibility of using the created mo...

Reliability of a concrete pipe culvert was tested under rail and embankment loads. In the finite element model soil-structure interaction and nonlinear behavior of the materials were taken into account. After a preliminary study three influential variables as random were selected for presented approach to probabilistic model, i.e. concrete strength, soil density and its modulus of elasticity. Because various concrete parameters can be easily derived from the compressive strength only this parameter was selected fo...

The paper deals with optimization of point cloud data processing for surface representation of objects with complicated structure. The model object in our research is represented by a coniferous tree with difficult structure obtained by the method of terrestrial laser scanning. Its precise geometric expression and vector representation is essential and it provides the basis to study the impact of natural conditions to the state and development of the coniferous tree using geographical information systems in the fi...

The aim of this article is to describe the possibility of increasing the service life of the rod eye on a tilting platform that is used to tilt heavy barrels between the two differences in heights in transport lines. This mode of transport was selected for the lack of space in a given area of a production line, which does not allow the implementation of an inclined plane, which would be structurally easier. Rotating those barrels by 90° that is achieved during this way of transport, is desired for subsequent techn...

The scientific paper deals with the multi-criterion optimization of the teeth that are used on the buckets of bucket wheel excavators. From past theory and practice, it is known that geometry of the tooth greatly influences the cutting parameters and the endurance and the strength of the tooth itself. The dependencies between the cutting forces, the penetrating forces, the specific energy on the rake angle and the relation between this last one and the robustness of the tooth are somewhat contradictory, so in the ...
