How does the diameter of the inhibition zones formed on agar plates containing bacteria (S. aureus, P. aeruginosa, E. coli) exposed to different strains of Lactococcus (1.2, 6.2, 10.2) change observed by well diffusion method and how may Lactococcus be used for food coating observed by disc diffusion method?
Full text linkBacteria have been usual sample organisms in biological research for a long time. But
they are not merely experimentation subjects. They are everywhere around us. From the
handle of the cup we use every day to drink water to the food we eat. While some of these
bacteria are harmless, some of them are. The negative effects of bacteria include sicknesses,
disruption of the biological balance of an organism and food decaying. For example, if raw
meat is left out for too long, it decays. As it makes contact with air, oxidation reactions occur,
encouraging bacterial growth on the meat. In time, as more bacteria forms, the meat decays
more and becomes unhealthy. When consumed, these bacteria release toxins that disrupt the
order of the intestines12. What if there was a way to prevent this? Maybe not fully but to some
extent. This research aims to identify three species of bacteria produced on decaying food and
inhibit them
How does the agricultural technique (hydrophonic and soil) effect on the harvesting time of strawberry (fragaria) plant?
Full text linkThe main purpose of this research work is to value hydroponics and soil cultivation under normal conditions. The main driving force of this research is the necessity to discover whether the application of hydroponic methods can substitute traditional soil agriculture, facilitating the problem of fertilization and agrochemical use to excessive production on soil health. By
comparing the growth rates of plants cultivated through hydroponics and soil farming, this research aims to ascertain whether hydroponics can offer comparable or superior rates of plant growth while reducing the reliance on synthetic fertilizers and minimizing environmental degradation
ÖN YARGILAR VE TOPLUM

Full text linkHakan Bıçakcı’nın Uyku Sersemi adlı romanında uzam değişimiyle yaşanan kayıpların odak figürün dönüşümüne etkisi nasıl işlenmiştir
Biomechanical Aspects of the Human Voice Production
Full text linkIn this Extended Essay, I explore the nexus between speech analysis, human physiology, and biomechanics. By delving into previous biomechanical studies, I aim to extract interpretations and formulas, which will serve as the foundation for my research. My primary objective is to investigate the frequency levels of head, mixed, and chest voices in individuals, and decipher the biomechanical implications inherent in these frequencies
Investigation of the Effect of Two Different Suspension Systems (Dependent and Independent) on the Angle (Inclination) Formed by the Vehicle with the Ground When Passing Over Bumps of the Same Size, with 7 Different Spring Constant in Their Suspensions
Full text linkThis test report examines how two distinct suspension systems dependent and independent affect the angle (inclination) that the vehicle forms with the ground using seven different spring constants, damping oscillations, and spring potential energy. Damping oscillation, which is the state in which an oscillator's damping enables it to quickly attain its equilibrium position
without oscillating back and forth around it, means that the energy change in the damping cannot be shown to be constant. Slope angle and spring constant are therefore not correlated linearly
Predictions and of the time required for a magnet drop inside a copper tube to fall for eight copper tubes with different diameters.
Full text linkThe aim of this investigation is to answer the question “How does the inner diameter of a copper tube affect the falling time of a magnet that dropped and freefalling through in it?” In this experiment, falling times of 4-millimeter diameter neodymium magnet falling through copper tubes with 5-6-7-8-9-10-11-12mm inner diameter, 25cm length are measured to evaluate the relationship of emf and the distance
The Age-Dependency of Jasmonate Levels Decay And Defense Metabolite Accumulation On Plant Insect Resistance
Full text linkDoes the Jasmonate hormone levels change with the increasing age of Lactuca sativa in comparison with a young plant, (4-weeks old) and old plant (8-weeks old) and how does this contribute to the survivability of Lactuca sativa measured by its resistance against the larvae Plutella xylostella and Helicoverpa zea deduced by the change of weight of the insects after feedin
