Application of guar ( L.) gum in food technologies: A review of properties and mechanisms of action.

With the world continuing to push toward modernization and the consumption of processed foods growing at an exponential rate, the demand for texturizing agents and natural additives has also risen as a result. It has become increasingly common to use thickening agents in food products to modify their rheological and textural properties and enhance their quality characteristics. They can be divided into (1) animal derived (chitosan and isinglass), (2) fermentation produced (xanthan and curdlan), (3) plant fragments (pectin and cellulose), (4) seaweed extracts (agar and alginate), and (5) seed flours (guar gum and locust bean gum).

Psychometric properties of the Persian version of the attitude scale for home care: a study of reliability and validity.

It is important to evaluate nursing students' attitudes toward home care to improve home health nursing profession and increase the number of nursing students willing to work in home care in the future. However, there is no valid and reliable scale for measuring attitudes toward this care method in Iran. This study aimed to determine the psychometric properties of the Persian version of the Attitude Scale for Home Care (ASHC) for nursing students.

Robust control of automatic voltage regulator (AVR) with real structured parametric uncertainties based on H and μ-analysis.

Within this work, a novel controller in terms of H infinity (H) and structured singular value decomposition has been presented to provide the robust performance of the Automatic Voltage Regulator (AVR) system Six real structured uncertainties in actuator, exciter and generator have been assumed for the linear transfer functions of the AVR system. Each uncertain parameter varies between a minimum and a maximum value due to the load variations in a period of time and aging effects over the life time. The efficiency of the presented design lies on two main reasons.
