Truth and it's benefit for personal development.
No full textThe article discusses various aspects of truth. Truth could be viewed as a truth of nature, as an individual truth of a person, as a truth of special and universal sciences, as a truth of a society. The aim of the article is to show that school can accomplish its mission if it relies on eternal truths of nature and spiritual life. Education should stay above the roetines of the every day life and raise to the heights of science, religion, art and technology. It is the point of departure from which the perspectives of tomorrow might be seen
Acoustic technique in the complex estimation of the texture of cereal products.
No full textThe study is devoted to the problem of the texture estimation of cereal products when analyzing the process of lying with the help of acoustic technique. Baker's goods of various quality produced in the "Kauno duona" enterprise were taken as the object of investigation. A special measuring test bed (cuvette with liquid where the sample with a frame was placed) and acoustic nonimpact level gauge had been constructed for the experiment. [...]
Optimization of fancy bread production process by acoustic technique.
No full textThe study is devoted to the improvement of the accuracy of the estimation method of fancy bread quality. The object of investigation - wafer sheets produced according to the production method and formulation applied in the Austrian company "Manner". While optimizing the process, the acoustically analyzed wafer sheets were prepared in four different ovens, namely SWP, SNL, NAP and MIG. [...]
Limeless production of blosse.
No full textThe present article deals with property shanges of hide in producing blosse. The system of sodium alkaline, sodium sulphide and sodium salts - chloride or sulphate or formiate was used for producing blosse. The influence of alkaline treatment parameters - amounts of sodium alkaline and sodium salts, temperature and duration of treatment on properties of hide as destroying of collagenous and noncollagenous proteins, changes in mass and sponginess were investigated. [...]
Parametriškai žadinamų vibroapsaugos sistemų tyrimas.
No full textThe numerical analysis of a two mass vibration isolation system with elastic links and of a four mass system with parametrically excited dynamics dampers has been carried out. It has been shown that the stiffness variation of one of the springs according to the sine law gives off some vibration isolation effect obtained as an amplitude decrease and a considerable change in the vibration spectrum. In the case of the four mass system the low frequency sinusoidal stiffness variation redistributes the vibration energy throughout the frequency range and reduces the amplitude of the main harmonic component of a reaction force. The results can be employed in the vibration isolation system design
Diagnostiniai matai dvimačiams atsitiktiniams koreliuotiems akustiniams procesams atskirti.
No full textTheoretical problem of developing distance-based diagnostical measure are considered for distinguishing random 2-d acoustical processes with the Gaussian distribution characterizing the technical status of dynamic objects, e.g. turbocompressors. The author proposes the function (1) and the analytical expression of diagnostical measures for the comparison of correlated Gaussian 2-d processes. [...]
