Investigating the Relationship Between Nicotine Dependence and Sleep Quality

To what extent does nicotine dependence, as assessed by the Fagerstrom Test, influence sleep quality, as measured by the Pittsburgh Sleep Quality Index (PSQI), in individuals with varying levels of dependency (non-smokers, low dependency, moderate dependency, high dependency)

How do human activity pollutants like car gasoline and waste cooking oil affect the pH and oxygen levels in water bodies consisting of the water plant Elodea? (Which can be correlated with Lake Pollution in Ankara)

Having lived in Ankara, I have always appreciated the scenic views of the lakes which are important natural features and recreational areas for the people. However, On my last trip to Lake Mogan in Ankara, I noticed an alarming layer of oil floating on the surface of the water, as well as a mild smell of petrol. Locals told me that the lake, which was once teeming with life, had fallen victim to pollution from the surrounding city, including the careless dumping of used cooking oil and road runoff containing petrol. This made me think about how these seemingly benign, everyday pollutants could be major issues for fragile aquatic environments. In particular, I found myself wondering about their effects on the more basic quality indicators of water, such as pH and concentration of oxygen, which are important for the existence of aquatic vascular plants like Elodea

The Impact of Human Development Index on Alzheimer's Disease Prevalence: A Cross-Country Analysis

To what extent does the prevalence of Alzheimer's disease vary across countries with different levels of development based on HDI

How does increasing the initial angle of a simple pendulum affect the rate of loss of energy?

A simple pendulum comprising a bob of mass ???? attached to a massless, inextensible string of length ???? has long been central to physics. Since Galileo Galilei’s famous observations in the 17th century, pendulums have not only inspired the design of accurate timekeeping devices (such as early mechanical clocks) but also contributed to breakthroughs in seismology (through the study of ground motion) and gravitational experiments (measuring variations in ????)

To what extent does Surface-Enhanced Raman Spectroscopy (SERS) enhance the Raman signal intensity of Brilliant Cresyl Blue, Crystal Violet, and Rhodamine 6G across different concentrations?

Raman Spectroscopy is an analytical method used for determining chemical species, it provides information related to chemical structure and detections on certain molecular interactions. It is based on elastic scattering of light by an illuminated sample. In this research, the aim is to evaluate 3 different chemical substances; brilliant cresyl blue, crystal violet, and rhodamine 6G which has ultra low concentrations. At that point, Surface Enhanced Raman Spectroscopy (SERS) is utilized

How does the thickness of SPF 30 sunscreen applied to a solar panel affect the voltage output generated, and what insights does this provide into the sunscreen’s effectiveness in blocking the UV light?

Being a very curious person, I have always wondered the working principles of a sunscreen. Back then, on holidays, I believed that the sunscreens acted as a mirror protecting our skin from the sunlight. Now of course I know that chemical sunscreens absorb UV rays and then convert them into heat, which is released from the skin. Their method is more about absorbing rather than reflecting. After acknowledging that, a question came into my mind. I knew that solar panels also absorb the light, so I wondered what would happen if I covered a solar panel completely with a sunscree

The Effect Of The Change In Oil Viscosity With Rising Temperature On The Service Life Of Engine’s Oils

What Is The Effect Of The Change In Oil Viscosity Measured by DIN Cup 4 With Rising Temperature in the 23-93oC Range On The Service Life Of Engine Oils

Relationship between the maximum height reached by the vertical projection of the sponge ring called ”the note”, and the weight and the speed of the motors.

This research studies the behaviors of a sponge ring named “the note” during its projection in a vertical axis. The vertical projection is done by a system called “the Shooter” which was designed and manufactured by myself. It is controlled using a computer and a joystick connected to it. Experimentally, the speed of the shooter and the mass of the object will be changed, and theoretically spring constant of the note and height approximations will be done to investigate the relationship and draw conclusions
