Assessing a thermal spike model of swift heavy ion-matter interactions via PdNi/Si interface mixing.

The thermal spike model (TSM), a widely accepted mechanism of swift heavy ion (SHI)-matter interactions, provides explanation for various SHI induced effects, including mixing across interfaces. We assess the validity of the model via tuning the electron-phonon coupling strength (G) by taking a series PdNi of a completely solid soluble binary, and then observing PdNi/Si interface mixing induced by a combination of 100 MeV Au ion irradiation and 4 keV Ar ion sputtering. If the TSM truly describes the SHI-matter interaction mechanism, any non-linearity in x-variation of G must also result in a similar non-linearity in the x-dependence of mixing.

Personality disorders and its association with anxiety and depression among patients of severe acne: A cross-sectional study from Eastern India.

Background: In many patients, emotional stress may exacerbate acne. Psychological problems such as social phobias, low self-esteem, or depression may also occur as a result of acne. The presence of acne may have some negative effect on the quality of life, self-esteem, and mood of the affected patients.

A study on self concept and adjustment of auxiliary nursing and midwifery (revised) students in a selected school of nursing, Purulia, West Bengal.

Nursing students are exposed to different types of stress, with which they have to make adjustments. Self concept Influences their capability of adjustment. The study was done to find out the levels of self concept in different dimensions and levels of adjustment in different spheres of the auxiliary nursing and midwifery (revised) [ANM(R)] students, to find out the association between their self concept and adjustment with different sociodemographic factors and to assess the correlation between self concept and adjustment of these students.
