Research topics in physicsPhysics has an important role in our life. Without physics and the work of
physicists, our modern life would not exist. Using physics, people created machines,
instruments and some different divices from the crudest to the most modern aspect.
Techology is developed more rapidly, more modern day by day.
Moreover, all other natural sciences- example chemistry, biology, medicinedepend
upon physics for the foundations of their knowledge. Physics holds this key
position because it is concerned with the most fundamental aspect of matter and
energy and how they interact to make the physical universe.
Physics has some main problems: mechanics, electricity and magnitism, heat,
wave and sound, optics, nuclear physics,...

Potential sources of uncertainties in nuclear reaction modelingIt is also well known that the knowledge of nuclear reaction mechanisms is at best approximate, and that their modeling relies on many parameters which do not have a precise physical meaning outside of their specific implementations in nuclear model codes: they carry both specific physical information, and effective information that is related to the deficiencies of the model itself.

Master of Science thesis: Physical layer signaling for the next generation mobile TV standard DVB-NGHThis Master of Science degree thesis aims at investigating, studying and developing the new physical layer for the new handled generation of terrestrial TV standard DVB-NGH. This new physical layer is based on the DVB-T2 physical layer specification, but it introduces several advanced mechanisms to allow the transmission of high definition TV services in mobile environments. The main objective of this thesis work is focused on illustrating the benefits of the new physical layer when compared to T2 physical layer.

Investigation of physical and mechanical properties of polyaniline/MMT nanocompositesPolyaniline (PANI) was synthesized chemically in an acidic medium in the presence of ammonium persulfate (APS) as an oxidizing agent. PANI/montmorillonite nano-composites were prepared in the presence of various amounts of modified clay (from 1 to 5 wt.%) by solution casting method.

Thread " Optical time resolved spin dynamics in III-V semiconductor quantum wells "This thesis presents time-resolved measurements of the spin evolution of transient carrier populations in III-V quantum wells. Non-equilibrium distributions of spin polarisation were photoexcited and probed with picosecond laser pulses in three samples; a high mobility modulation n-doped sample containing a single GaAs/AlGaAs quantum well, an In0.11Ga0.89As/GaAs sample containing three quantum wells and, a multi-period GaAs/AlGaAs narrow quantum well sample.

Sleep quality and associated factors among third-year medical students at Can Tho University of Medicine and PharmacySleep is a condition of reduced stimulation that allows the body to recoup and re-energize. Hence, poor sleep will affect the body's capacity to think and focus, raise the risk of health issues, and have a negative impact on learning, causing occupational mistakes and accidents. A busy theoretical study schedule, a clinical practice schedule at the hospital and a tight exam schedule will have certain impacts on the sleep quality of medical students.
