Environmental Psychology—Man and His Physical Setting

determination of some physical and mechanical properties red bean

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...

Wigner Centennial: His Function, and Its Environmental Decoherence

In 1983, Wigner outlined a modified Schrödinger—von-Neumann equation of motion for macroobjects, to describe their typical coupling to the environment. This equation has become a principal model of environmental decoherence which is beleived responsible for the emergence of classicality in macroscopic quantum systems. Typically, this happens gradually and asymptotically after a certain characte...

Predictors of physical restraint in a psychiatric emergency setting

Background: Considering the negative consequences of using physical restraints, we conducted this study to identify patients who are more frequently restrained in a psychiatric emergency ward as an initial step to limit the use of restraint to the minimum possible.   Methods: This was a retrospective case control study conducted in Iran Psychiatric Hospital in Tehran, Iran. We reviewed the f...

Physical Geography and Environmental Sustainability

In this introduction to the Special Issue on Physical Geography and Environmental Sustainability, the links between a variety of physical landscapes located throughout the world and long-term wellbeing are considered from a systems approach. Twelve papers were published as part of this call, with half from Asia, especially China. They represent a contribution across topographic landscapes, from...
