To study relationship between grain yield and important agronomic traits of rapeseed in paddy fields as second culture, fourteen varieties of spring rapeseed were grown in a randomized complete block design of experiment with three replications at Rice Research Institute of Iran, Rasht, during 2005-2006. Analysis of variance showed that there were significant differences between varieties for m...
A ring R is radical if there is a ring S (with unit) such that R = J (S) (the Jacobson radical). We study the commutative subdirectly irreducible radical rings and show that such a ring is noetherian if and only if is finite. We present a reflection of the commutative radical rings into the category of the commutative rings and derive a lot of examples of the subdirectly irreducible radical rin...
The present paper aims to investigate the amount of multi-cultural education components in the textbooks of secondary schools from 2013 to 2014. It is conducted through text-analysis. The components of Multi-cultural education were initially collected from theoretical text and research background using document analysis and then they were numbered in the textbooks of secondary schools. The unit...
Secondary Malignant Neoplasm(SMN) is one of the late effects of childhood cancer. Among secondary malignancies, acute myeloid leukemia(AML) is the most common and life-threatening neoplasm. Secondary acute lymphoblastic leukemia(ALL) is rare and only 10% of SMN is ALL. Patients with Wilm’s tumor are not protected from the secondary cancers after the primary diagnosis. Among patients...
Abstract. Human capital is a prerequisite for sustainable development; since education has the most human capital, paying attention to it will not only ensure individual security but also ensure the security of society. Therefore, understanding the education sector in a wide range of dimensions has been considered by researchers and policy makers. The National Education Account is a framework f...
Introduction: Proton therapy is newer therapeutic method for early stage breast cancer. Proton beams release most of their energy in the Bragg peak and then will be a rapid decline in their end. When protons interact with matter, produce secondary particles like neutrons and gammas, and these unwanted radiation has no beneficial effect and also is believed to increase the risk ...
