Properties of light and heavy baryons in light cone qcd sum rules formalism
Azizi, Kazem; Özpineci, Altuğ; Department of Physics (2009)
In this thesis, we investigate the masses, form factors and magnetic dipole moments of some light octet, decuplet and heavy baryons containing a single heavy quark in the framework of the light cone QCD sum rules. The magnetic dipole moments can be measured considering radiative transitions within a multiplet or between multiplets. Analyzing the transitions among the baryons and calculating the above mentioned parameters can give us insight into the structure of those baryons. In analyzing the aforementione...

Numerical investigation of circulating fluidized bed riser hydrodynamics for concentrating solar thermal receiver applications
Bilyaz, Serhat; Tarı, İlker; Department of Mechanical Engineering (2015)
Various heat transfer fluids and thermal storage materials are considered for concentrating solar power systems to improve the storage capability of the system which compensates the fluctuating behavior of the solar resources. Solid particles can be a good alternative since they have high sensible heat capacity. In addition, they are cheap, environmentally benign and chemically and mechanically stable at high temperatures. In this thesis, hydrodynamics of circulating fluidized bed solar receiver was numeric...
Quantitative electrostatic force measurement in AFM
JEFFERY, Steve; Oral, Ahmet; Pethica, John B. (2000-04-02)
We describe a method for measuring forces in the atomic force microscope (AFM), in which a small amplitude oscillation(similar to 1 Angstrom(p-p)) is applied to a stiff(similar to 40 N/m) cantilever below its first resonant frequency, and the force gradient is measured directly as a function of separation. We have used this instrument to measure electrostatic forces by applying an ac voltage between the tip and the sample, and observed a variation in contact potential difference with separation. We also sho...
Comparison of hypermedia learning and traditional instruction on knowledge acquisition and retention
Yıldırım, Zahide; Aksu, M (2001-03-01)
A comparison was made of hypermedia learning environments and traditional instruction in terms of contribution to declarative, procedural, and conditional knowledge acquisition and retention in a specific subject area through a pretest-posttest control-group design. Thirty-nine 9th-grade biology students were assigned to experimental (hypermedia learning environment) and control (traditional instruction) groups through a matched-pair technique. Both groups were given pre-, post-, and retention tests. Postte...
