Parity nonconservation (PNC) was studied for 24 p-wave neutron resonances in 238U from 10 to 300 eV by measuring the helicity dependence of the total neutron cross section with an improved experimental apparatus. Six resonances show statistically significant (greater than 2.9σ) parity violation. An analysis treating the PNC matrix elements as random variables yields a root-mean-square PNC matri...
Abstract The power output of a straight-bladed H-rotor Darrieus vertical axis wind turbine (HDVAWT) is explored in this article. comparisons are performed between the NACA0018 airfoil and series Kline Fogelman modified airfoils. computational fluid dynamics findings first cross-checked with experimental data, processes validated as consequence. Then, CATIA, 12 airfoils were constructed by modif...
به منظور تعیین اهمیت نسبی برخی پدیده‌های دفاعی در مراحل قبل و بعد از نفوذ Cercospora beticola در چغندرقند، روند آلودگی شامل مراحل جوانه‌زنی اسپور، نفوذ عامل بیماری و پیشرفت آن در بافت مزوفیل در برگﻫای جوان و بالغ دو ژنوتیپ مقاوم (FD 0018, HM 1836) و یک ژنوتیپ حساس چغندرقند(236) مورد مطالعه قرار گرفت. نتایج این مطالعه نشان داد که مراحل قبل از نفوذ شامل جوانه‌زدن اسپور و نفوذ بیمارگر، اهمیتی در م...
Despite its importance in global fishery production as the world's second-largest producer, Indonesia is not one of top ten fish exporting countries. This study uses constant market share analysis to examine Indonesia's export performance. The data was collected from United Nations International Trade Statistics Database and covered exports 1999 2019. Indonesian products are classified using fo...
