One of the most important challenges in health management is nurses’ turnover. While studies indicated that Dual Career Ladder can reduce the specialist turnover by providing career promotion opportunities. In order to retain nurses, we decided to design Dual career ladder for nurses. Data in this developmental and qualitative research were collected in 2016 conducting semi-structured and in-depth qualitative interviews to reach theoretical saturation, and analyzed according to Grounded theory Method. Participants were 38 elite Iranian nurses in educational, managerial and clinical departments. Nurses in each group had to have specific criteria to enter the research. Our findings revealed the specialist and managerial nurses, specialist and managerial qualifications, and required specialist and managerial posts in Iranian nursing. Finally, the new model of nursing career was designed. This paper offers the DCL in Iranian nursing as a revolutionary. Future researches should examine this career model in pilot to assess its effect on turnover reduction, specialization, and career promotion in nursing. Moreover, researchers should consider local and national conditions in designing this model. The paper suggests implementing this career model to specialize nursing and retain these human capital based on necessary requirements.
Ultrasound has attracted interest in food engineering because of its promising effects on conservation. This can be applied to develop processes aimed at improving quality and safety. The objective of this work was to explore the effects of high intensity ultrasound (US) on the color profile, changes in surface myoglobin, as well as on shear force. It was performed on the Longissimus thoracis muscle of meat pork cut into 3x2x3 cm plates, which were subsequently US at 40 kHz for 5, 10 and 15 min. The results were analyzed in Minitab 16.0.1 using ANOVA (P < 0.05) and Tukey\
