5 January 2007
Kristina KAZLAUSKIENĖ - Kaunas University of Technology
Design and Research of Biomechanical Models of Human with Joint Replacements
Technological Sciences - Mechanical engineering - Summary

One of the most actual problems during joint replacement surgery is to assure accuracy of insertion of the elements of total joint replacement, because due to deviation of the joint centre human movements does not correspond the one possessed while being healthy, moreover, wrong position can cause shorter longevity of the joint replacement. Bone remodeling (resorption) caused by inappropriate distribution of long lasting loading is also relevant, because can produce weakening and even break of the bone-biocement junction and loosening of the implant.

Aurimas JAKŠTAS - Kaunas University of Technology
Investigation of Precision Length Calibration Systems
Technological Sciences - Mechanical engineering - Summary

Precision Engineering is the foundation of all modern manufacturing. While developing precision machines that comprise the technical basis of high technologies the essential quality of a new system is the accuracy of that system. The key criterion for precision machines design is an error budget that determines the range of errors that can be tolerated at each design stage or production process.

Lina KAVALIAUSKIENĖ - Kaunas University of Technology
Investagation of Wear Resistant Layers Produced by Overlaying Welding of Metals and Alloys Powder
Technological Sciences - Mechanical Engineering - Summary

In the presented work coatings made by automatic arc welding under the flux using unbinded powder of materials spread on the surface of overlayed surface or inserted into the flux were investigated.


19 January 2007
Agnė DIGAITIENĖ - Kaunas University of Technology
The Application of New Lactic Acid Bacteria with Antimicrobial Activity and Pre-Gelatinized Products in Wheat Bread Production
Technological Sciences - Chemical Engineering - Summary

Because bread has a rather short shelf life and is liable to microbiological spoilage and goes easily moldy the aim of the work was to isolate lactic acid bacteria (LAB) with antimicrobial activity from spontaneous rye sourdoughs and apply the new lactic acid bacteria with antimicrobial activity together with pre-gelatinized products in wheat bread production.

Jolanta ŠADAUSKIENĖ - Kaunas University of Technology
The Impact of the Hydro-Properties of the Painted Thin-Layer Render on the Durability of the Walls Insulated With Mineral Wool
Technological Sciences - Construction Engineering - Summary

With introduction of external thermal insulation of building walls with application of painted thin-layer render, more defects appear due to the accumulated moisture inside the walls. The moisture can access into the wall’s construction from the outside through paint coating due to the rain water permeability and it can be accumulated from inside due to the large water vapor resistance of paint coating.


23 February 2007
Aleksandras ILJINAS - Kaunas University of Technology
Synthesis of Iron and Iron Oxides Thin Films Using Reactive Magnetron Sputtering Methods
Technological Sciences - Material Engineering - Summary

During the last decade, the investigation of spin-dependant electrical transport from ferromagnetic materials to paramagnetic or diamagnetic materials is one of the underlying and greatly financially supported materials sciences areas. In our days the highest potential has conductive oxides magnetite (Fe3O4), chromium oxide (CrO2) and several other oxides multilayer structures with the other paramagnetic and diamagnetic metals, semiconductors and dielectrics.

Arūnas STANKEVIČIUS - Kaunas University of Technology
Investigation of Influence of Hydrodynamical Factors to Reproducing Air Volume and Flow Rate Values
Technological Sciences - Energetics and Thermal Engineering - Summary

Efficient usage of power resources and their saving are directly related to their accurate accounting. Natural gas is very important source of energy and its consumption is constantly growing.
