PURPOSE To demonstrate a method of generating patient-specific, biologically-guided radiotherapy dose plans and compare them to the standard-of-care protocol. METHODS AND MATERIALS We integrated a patient-specific biomathematical model of glioma proliferation, invasion and radiotherapy with a multiobjective evolutionary algorithm for intensity-modulated radiation therapy optimization to const...
In this study, a phenomenological tissue damage model has been developed to describe the fatigue-induced stress softening and permanent set of biological tissues. Since damage evolution is an irreversible dissipative process, following thermodynamic principles, an equivalent strain proportional to the strain energy of the material is employed as the damage criterion. The maximum equivalent stra...
مقدمه و هدف : یکی از عوامل مهم و تاثیرگذارجهت دستیابی به انطباق بدون تنش در پروتزهای متکی بر ایمپلنت، انجام قالبگیری دقیق می باشد. دو روش قالبگیری مستقیم و غیرمستقیم برای انتقال موقعیت ایمپلنت از دهان به کست کار وجود دارد. هدف از انجام این مطالعه بررسی دقت وسایل رایج جهت قالبگیری به روش غیرمستقیم درسه نوع سیستم مختلف ایمپلنت دندانی و مقایسه آنها با روش مستقیم می باشد. مواد و روش ها : در...
The hygiene tissue industry has an extensive global market that is quickly growing. Market research indicated softness one of consumers’ most highly desired properties. For certain products (specifically bath tissue), this property can influence prices. A better understanding the science would allow companies to engineer soft more economically and efficiently. Softness a subjective perception r...
BACKGROUND with today's 21st century technological advancements, it is expected that individuals will either retain their natural teeth or obtain functional tooth replacements throughout their entire life. Modern dental therapies for the replacement of missing teeth largely utilize partial or complete dentures and titanium implants capped with prosthetic crowns. Although these prostheses serve ...
