More Equienergetic Signed Graphs
The energy of signed graph is the sum of the absolute values of the eigenvalues of its adjacency matrix. Two signed graphs are said to be equienergetic if they have same energy. In the literature the construction of equienergetic signed graphs are reported. In this paper we obtain the characteristic polynomial and energy of the join of two signed graphs and thereby we give another construction ...
متن کاملMore skew-equienergetic digraphs
Two digraphs of same order are said to be skew-equienergetic if their skew energies are equal. One of the open problems proposed by Li and Lian was to construct non-cospectral skew-equienergetic digraphs on n vertices. Recently this problem was solved by Ramane et al. In this paper, we give some new methods to construct new skew-equienergetic digraphs.
متن کاملDo the Emotionally More Intelligent Gain More from Metacognitive Writing Strategy Training?
Though privileges ascribed to various facets of language learning strategy training have long been espoused with regard to varied language skills and components, the role some individual variables such as emotional intelligence might play in this respect seems to have received very scant attention. The researchers in the current study embarked on a probe into the impact of metacognitive strateg...
متن کاملRamadan fasting: Do we need more evidence?

However, available evidence regarding the health-benefits of Ramadan fasting is scarce and highly contentious. Although Islam exempts patients from fasting, many fast conceivably, and their clinical condition is prone to deterio...
متن کاملبررسی تکمیلی زیستشناسی پروانه‌ی برگ‌خوار درختان جنگلی (Ennomos quercinaria (Lep: Geometridae در استان مازندران
شبپرهی برگ‌خوار (Ennomos quercinaria (Lep.: Geometridae نقش مهمی در ایجاد خسارت روی درختان جنگلی در مناطق مختلف دنیا دارد. در طی سالیان اخیر این آفت به‌طور متناوب در جنگل‌های استان مازندران طغیان داشته است. مطالعه‌ی ویژگی‌های زیستی حشره در شرایط آزمایشگاهی نشان داد که دارای 6 سن لاروی است. متوسط طول دوره‌ی لاروی این حشره 74/3± 16/46 روز می‌باشد. رنگ لاروها از سبز تا قهوه‌ای متفاوت می‌باشد. ش...
