different discrete models of population dynamics of certain insects have been investigated under various feasible conditions within the framework of nonlinear dynamics. evolutionary phenomena are discussed through bifurcation analysis leading to chaos. some tools of nonlinear dynamics, such as lyapunov characteristic exponents (lce), lyapunov numbers, correlation dimension, etc. are calculated ...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
abstract the present thesis seeks to critically read george orwell’s nineteen eighty-four and animal farm in the light of louis althusser’s thought and theory. the present thesis proceeds to examine and demonstrate althusser’s major concepts including ideological state apparatuses (isas), repressive state apparatuses (rsas), the structure, the subject, and ideological interpellation which r...
Background. Hypertrophic cardiomyopathy (HCM) is the most common inherited heart disease; it characterized by left ventricular (LV) hypertrophy that cannot be explained hemodynamic causes.

Poor economic conditions of dairy farmers do not allow them to purchase adequate conventional energy and protein supplements. Locally available non-conventional energy and protein sources can be used as alternatives, cheaper than conventiona...

This study considers an EOQ inventory model with advance payment policy in a fuzzy situation by employing two types of fuzzy numbers that are trapezoidal and triangular. Two fuzzy models are developed here. In the first model the cost parameters are fuzzified, but the demand rate is treated as crisp constant. In the second model, the demand rate is fuzzified but the cost parameters are treated ...
