摘要： The invention belongs to the field of microbiology, more precisely to the field of production of various microbial products such as bacterial cellulose. The present invention relates to an extract from food wastes for the cultivation of microorganisms and a process for obtaining said extract. The essence of the invention is that the source material for preparation of a novel growth medium is grape pomace, said pomace obtained after squeezing fluid from fruit and comprising mostly envelopes and seeds, which are processed by the following steps:
a) lyophilisation of grape pomace,
b) grinding of grape pomace lyophilised in step a) with any suitable device, preferably with a pulveriser,
c) addition of water to grape pomace ground in step b), wherein the maximal final pomace concentration is 30%,
d) autoclaving the mixture obtained in step c), at a temperature of at least 121 °C and a pressure of 1.1 bar, wherein the duration is at least 20 min with the possibility of time reduction if autoclaving is performed at a higher temperature,
e) separation of solid particles from the fluid part of the mixture autoclaved in step d), such as decantation, sedimentation, centrifugation, filtration or draining in order to obtain a liquid medium or an extract, respectively, which is suitable for use as a growth medium for microorganisms.

摘要： The invention relates to a method and apparatus for determining the reflectional symmetry of a 2D or 3D geometric object described by its boundary. Many objects in nature and those made by man have the reflectional symmetry, making the invention versatile. Information about object's symmetry can be crucial for detecting disease changes in the analysis of medical images, recognizing of living organisms in the environment, automatic discovering of vehicle damages in insurance services, finding defects in the manufacturing of mechanical or construction elements, and design defects in all branches of industry. This invention rasterizes the boundary data of a geometric object into the internal cell structure. Then, several steps are applied to determine whether the object is symmetrical within the desired tolerance or not. The invention is applicable for both 2D and 3D geometric objects, which may contain also the holes nested to an arbitrary depth.

摘要： An axisymmetric chiral auxetic structure is assembled from chiral unit cells, uniformly or non-uniformly axisymmetrically distributed in space to form a cylindrical or a spherical shape. The chiral cells have curved struts (2), which connect at nodes (1). The outer surface of unit cells may be solid, thereby forming closed cells or channels in the structure. A spatially graded chiral structure can be created by changing the length, thickness and curvature of unit cell struts or walls throughout the structure. The axisymmetric chiral cellular structure with cylindrical or spherical shape exhibits auxetic behaviour under mechanical loading in all characteristic directions of the structure and does not have imperfect outer cells with sharp edges and loose struts that represent a hazard for possible injuries and affect structure properties.

摘要： The invention solves the technical problem of the too long connections between the output from the secondary winding and an output rectifier also reducing the need for intensive cooling of rectifier means by integrating the rectifier means in the form of power diodes or MOSFET transistors into the parts of the secondary winding, where the arrangement is not more complex compared to the conventional solutions, however, it enables substantially shorter output connections. The proposed modified structure changes the electrical parameters of the welding system in such a way that, despite the required unchanged maximum value of the welding current and the use of rectifier means in the form of power diodes or MOSFET transistors, it is possible to further reduce electrical losses in secondary connections that become shorter, while simplifying also the cooling of rectifier means in the form of power diode or MOSFET transistors, which, with the proposed integration of secondary windings with output rectifier means in the form of power diode or MOSFET transistors, is cooled indirectly simultaneously with the cooling of the secondary winding. The proposed embodiment allows a significant increase in the power density of the welding transformer with an output rectifier. Because of the change in the electrical properties of the secondary part of the system, it is also possible to operate at slightly higher frequencies than 1 kHz, without parallelizing the secondary winding.

摘要： The invention is a procedure for dynamic deep etching and particle extraction for aluminium alloys, applicable for quality control of products made of aluminium alloys, and for investigation of aluminium alloys using scanning and transmission electron microscopy, as well as X-ray diffraction. The mode and sequence of individual stages of the procedure enables uniform dissolution of aluminium matrix throughout the entire volume of a specimen by using a solution composed of iodine, tartaric acid and methanol, in which the components have concentrations determined according to specimen dimensions. It is important in this regard that the solution penetrates into the interior of the specimen at specific sites only and that the surface oxide layer remains compact. An ultrasonic device is applied in the procedure, effecting the movement and penetration of the electrolyte into the interior of the specimen, and thus enhancing the dissolution process.
