A qualitative study to explain the determinants of naswār consumption from the point of view of its consumers.

Background: One of the health problems related to tobacco that is increasing in society is the consumption of naswār. This study aimed to investigate the determinants of naswār consumption from the point of view of its consumers.

Materials And Methods: In this qualitative study, 47 men with an age range of 23- 54 years who consumed naswār from the southern cities of Fars province in Iran were selected and interviewed.

Facilitators and Barriers to adherence to antiretroviral therapy among incarcerated people living with HIV in Iran: insights from a qualitative study.

Background: Ensuring consistent adherence to antiretroviral therapy (ART) is crucial for effective HIV treatment and achieving viral suppression. Within prisons, the prevalence of HIV is notably high, and incarcerated individuals face an increased risk of transmitting the virus both during and after incarceration. However, facilitators and barriers to ART adherence among these individuals in low- and middle-income countries remain inadequately explored.

Influence of Klein edges on Phononic and electronic transport in circular graphene devices.

We study the electron and phonon transport coefficients of graphene disks and rings in the presence of Klein edges. We examine the transport characteristics by changing of the outer and inner radius using the non-equilibrium Green's function approach. We find that the effect of the nanodisk radius is highly influenced by the Klein edges, such that at small radii, armchair Klein edges can help preserve the electronic transport coefficient from suppression, while zigzag Klein edges significantly suppress the transmission spectrum, highlighting the importance of the edge atom sublattice.
