The Design of Microfluidic Pump For Medical Field
A microfluidic pump (MFP) is designed in professional drawing program AutoCAD and produced by using 3D printer in this project. It is aimed to develop microfluidic pump which is cost-effective and has practical usage during the treatment processes of diseases such as cancer and diabetes. During the experiments we characterized our pump and examined that uniquely designed MFP has suitable…

The capability of artificial intelligence to identify Estonian plants
The aim of this study was to evaluate the accuracy of artificial intelligence based plant image identification applications among the Estonian Flora. Automated identification is relatively new and has not been examined using an extensive dataset. Two applications, Pl@ntNet and Flora Incognita, were used to identify 1501 images from a national database (551 taxa) and 1000 observations from field conditions…
The Aerodynamics of Paper Airplanes
How airplanes fly is one of the most important questions within the field of air- and spacecraft development. By studying how paper airplanes behave, one can develop knowledge on flight principles. The purpose of this scientific report was to gain a better understanding of how the design of a paper airplane affected the longest possible flight distance. The studies show…

Temperature-dependent toxin production of the cyanobacterium Microcystis aeruginosa
In recent years, the occurrence of HABs – harmful algae blooms – in freshwater systems have become more frequent, as water temperatures are rising due to global warming. These blooms are formed by fast reproducing algae or cyanobacteria and can have serious consequences for aquatic organisms, as some bloom forming species produce toxins that inhibit the growth of other aquatic…
Synthesis of helper lipid as a component of cationic liposomes for gene therapy
Gene therapy is a promising approach to the treatment of hereditary and acquired diseases, which consists in the introduction of therapeutic nucleic acids into the cell for a targeted change in its functions. Cationic liposomes are able to protect such nucleic acids from biological factors, and to deliver them into target cells. An important component of cationic liposomes are helper…

Synthesis and characteristic of a composite based on metal oxides and silica for use in photocatalysis and capturing pollutants
Our group’s motto in abbreviated form is (CEP) which we interpret as contamination, experimentation and purification. After discovering a gigantic environmental problem, which is water CONTAMINATION by polycyclic aromatic hydrocarbons and nanoplastics, we decided to take the initiative and started our own EXPERIMENTS which enabled us to develop the nanoparticles (NPs) which have the ability to PURIFY water. Our aim…
SUSTAINABLE SOLUTION FOR CROP DAMAGE CAUSED BY DROUGHT
Due to global warming, droughts cause great stress to plants, slow down their growth, reduce the supply of plant foods, increase the cost to the customer. Farmers use expensive biostimulants in order to save crops during droughts. So, I decided to look for an effective alternative – calcium compounds, which are widely used in agriculture to regulate soil acidity, and…
Study of microbiological structures with the purpose of creating MEMS actuators with various applications in medicine
Our paper presents the study of cellular structures with the purpose of creating microactuators, some of which have applications in medicine. The microactuators were developed after studying various cellular structures ranging from the F1Fo ATP synthase to the sporangium of the Polypodium aureum fern. The geometrical parameters of the sporangium have been used along with additional data to develop diverse…
Strong electric field electroosmosis – physical principles and measurements in the strongly nonlinear regime
Electroosmosis is the motion of an electrically neutral fluid under the influence of an electric field due to interface breaking of local electrical neutrality. We analyzed a simple system in which there are non-linear effects present, related to the bulk electrolyte depletion caused by the accumulation of ions at the electrodes. The apparent electroosmotic velocity was measured and the zeta…
Strategies of the board game African Star
We studied the strategies of popular nordic board game African star with computer simulation. We digitized the game using Python coding language and built strategies that navigate the game board using graph theory path algorithms. We divided testing of the strategies into phases. We found out that Cairo is a bit better starting position than Tangier but one shouldn’t rush…
