The removal of copper (II) ion by using ultrasound pre-treatment to increase the pores structure and surface area on peanut husk powder via direct sonication (ultrasound probe) and indirect ultrasound (ultrasound bath) at powder level 3.5 W. In previous studies, researchers had applied ultrasound simultaneous with adsorption process. This method is not suitable to treat huge amount of heavy met...

in order to study the effect of ultrasound (us) on bone healing, a complete transverse fracture was made in the right radius of adult male rabbits by a cutter. 52 rabbits were used: group i. control (n= 17): group 2. test (n:=: 15): group 3, intact (n= i) and group 4 (n= 12) who were examined only for evaluation of the cutter effects in detail. 7 animals were operated with a gigli saw. the test...

a 29-year-old woman with systemic lupus erythematosus (sle) presented with palpitation and neck swelling. initial sonography showed an ill-defined hypoechoic lesion in the right thyroid gland, mentioning subacute thyroiditis. the patient received conservative care for one week. however, her neck swelling worsened and she complained of dyspnea. follow up sonography showed marked enlargement of b...

lingual thyroid (lt) is a rare developmental thyroid anomaly usually affecting. although the exact pathogenesis of this ectopic, accessory thyroid tissue is not known, it generally originates from epithelial tissue of non-obliterated thyroglossal ductus. in this report, a case of lingual thyroid in a 45- year old male patient with difficulty in breathing and swallowing complaints for five years...

Objective(s) Sonodynamic therapy is a physical treatment which utilizes ultrasound waves with an appropriate sensitizer such as protoporphyrin IX (PpIX). The activation of sensitizer depends on cavitation, and therefore, high intensity ultrasound is an important necessity. Beside, high intensity ultrasound can induce side effects on the healthy tissues which have surrounded tumor. The particle...

Introduction: One of the combination therapies for the treatment of cancer is ultrasound with other agents, which has received considerable attention in recent years. Ultrasound causes cavitation phenomenon that can produce some effects, such as; Reactive Oxygen Species (ROS), which results in damage to cancer cells. When a particle is in liquid, the cavitation threshold decrea...

با توجه به عدم­‌قطعیت‌های حاکم بر پروژه‌های عمرانی و تفاوت بارز آن‌ها صنایع خدماتی تولیدی از منظر محدوده زمان‌بندی کار، عوامل محیطی چالش‌های اجرایی، پیمانکاران کارفرمایان همواره اختلافات دعاوی قراردادی مواجه هستند. در چنین شرایطی، پژوهشی موضوع ضروری است. هدف این پژوهش، شناسایی مرتبط فرآیندهای طرح ادعا رویه مواجهه چالش‌ها راستا، لوایح ادعایی ارزیابی شدند. روش پژوهش به‌صورت کمّی ـ کیفی مشتمل بررسی...

a 30-year-old woman presented with a palpable subcutaneous nodule in the areolar region of the left breast. sonomammographic examination revealed 2 cystic lesions showing typical “filarial dance” as vigorous twirling movement of multiple curvilinear echoes with mixed red blue color doppler signals that was non-rhythmic, nonpulsatile, and the characteristic pulse doppler trace due to irregular w...
