abstract   background: cosmetic rhinoplasty is now carried out increasingly in an attempt to solve the psychological and social problems of people who are discontent with their nose. little is known about either the psychological status of persons who seek rhinoplasty or potential psychological changes following surgery. the challenge that faces surgeons, is how to identify, before surgical int...

The composition and structure of Calcium-Silicate-Hydrate (C-S-H) phases depends on various reaction parameters leading to its formation. Molecular Dynamic simulation studies probing the formation C-S-H are generally computationally expensive can reach only very short time scales. Herein, we propose a coarse graining approach model C-S-H, using patchy particles modified Patchy Brownian Cluster ...

shiftwork that affects diverse aspects of human life is arranged in various schedules. the main purpose of this study was to compare psycho-social problems among employees working in different 12-hour shift schedules of iranian petrochemical industries. this cross-sectional study was carried out at eight petrochemical companies in asalooyeh area. the study population consisted of 549 shift work...

This study investigates the effect of gluconate, a carboxylate anion, and three uncharged hexitols, D-sorbitol, d-mannitol D-galactitol on solubility C-S-H. Thermodynamic modeling is used to determine kind amount Ca-organic-silicate-OH complexes that potentially form in conditions studied. All organics with calcium hydroxide. In addition, heteropolynuclear calcium, hydroxide silicate are observ...
