سابقه و هدف: گیاه­ پالایی مقرون­ به­ صرفه سازگار با محیط زیست است که در آن گیاه از توانایی‌‌های طبیعی خود برای بازیابی استفاده ‌‌می‌‌‌کند. گیاهان مورد باید توانایی انباشت مقادیر زیادی آلاینده‌‌های فلزی را بدون ایجاد سمیت آنها داشته باشند. امروزه افزایش جمعیت جهان به دنبال توسعه صنایع کارخانه‌‌ها، بر میزان پساب‌‌های وارده غالبا حاوی فلزات سنگین مختلف ‌‌می‌‌‌باشند، افزوده ‌‌می‌‌‌شود. تاثیرات مخرب...

In the present study it was demonstrated that the NICS(zz)-scan patterns along with symmetry-based selection rules can unequivocally probe the antiaromaticity in a wide range of antiaromatic organic and inorganic rings/cages. The NICS(zz)-scan profiles typical of antiaromaticity correspond to symmetric curves around the axis perpendicular to the ring plane with the positive NICS(zz)(R) values d...

Scholars and policy makers have long debated the causes of the spectacular economic success achieved by the East Asian newly industrialisin g countries (NICs) as well as the lessons that other developing countries can learn from this development experience. Latin America started to industrialise many decades before the East Asian NICs and yet was quickly overtaken by them in the last few decade...

Part of the University of Campinas (UNICAMP, www.unicamp.br), the Interdisciplinary Nucleus of Sound Communication (NICS, www.nics.unicamp.br) was founded in 1983 by the composer Raul do Valle and collaborators. Since then, NICS has maintainined a longstanding list of participations in the academic and artistic musical scenario, specially the ones concerning the application of mathematical mode...

Aromatic compounds are characterised by the presence of a ring current when in a magnetic field. As a consequence, current density maps are used to assess (the degree of) aromaticity of a compound. However, often a more discrete set of so-called Nucleus Independent Chemical Shift (NICS) values is used that is derived from the current density. It is shown here that there is no simple one-to-one ...

Noninvasive cortical stimulation (NICS) can produce analgesic effects by means of repetitive transcranial magnetic stimulation or transcranial direct current stimulation (tDCS). Such effects have been demonstrated on chronic ongoing pain, as in acute provoked pain. The investigation of induced changes in the perception of experimental pain by NICS could help clinicians and researchers to better...

هدف: پیشرفت جوامع بالاخص کشورهای درحال توسعه تا حد زیادی در گرو گسترش نهادهای دانشگاهی است. هم‌چنین یکی از مهم‌ترین ویژگی‌های آموزشی، درهم‌تنیدگی ساختارهای آموزش و اشتغال واقع هر آموزشی باید بازدهی یا توجیه اقتصادی داشته باشد که عالی‌ترین نوع آن ایجاد متناسب با فراگیر بر این اساس پژوهش حاضر به بررسی وضعیت راهیابی دانشجویان فارغ‌التحصیلان کارشناسی ارشد دکتری رشته تکنولوژی بازار کار عوامل مؤثر نظ...
