This study examines causal link between energy use and economic growth for five South Asian countries over period 1971-2006. Panel cointegration, ECM and FMOLS are applied for short and long run estimates. In short run unidirectional causality from per capita GDP to per capita energy consumption is found, but not vice versa. In long run one percent increase in per capita energy consumption tend...

The temperature coefficient of van't Hoff, Q(10), for growth of frog carcinoma in vitro over a range of 20-35 degrees C, averages 2.5. This value is closely similar to those obtained for various forms of normal growth. The values of the temperature coefficient slightly but progressively decrease with advancing age of the cancer colonies. A similar relation obtains in many but not in all forms o...

F rom the viewpoint of economic theories, total factor productivity (TFP) is the most important component that leads to economic growth and development. The main purpose of this study was to evaluate the impact of knowledge-based economy on total factor productivity in the member countries of the Middle East and North Africa (MENA) region. For this purpose, the panel data regression analysis ha...

determination of crops water requirement in different environmental conditions is essential for preparation of precise and suitable irrigation scheduling. the effect of soil compaction and texture on crop coefficient and evapotranspiration of maize was investigated in this study, which was conducted as a factorial experiment with a completely randomized design in a research farm in jey and qaha...

It has recently been shown that the minimum distance of the ensemble of repeat multiple accumulate codes grows linearly with block length. In this paper we present a method to obtain the minimum distance growth rate coefficient of double-serially concatenated codes and determine the growth coefficient of the rate 1/2 double serially concatenated code consisting of an outer memory-one convolutio...

The relationship between economic growth and energy consumption is one of the hot topics in economic research. There are many literatures concern about this topic from theoretical and empirical viewpoint. This paper applies panel unit root, heterogeneous panel cointegration and production function to investigate the relationship between energy consumption and economic growth within a multivaria...

We consider the linear growth and fragmentation equation ∂ ∂t u(x, t) + ∂ ∂x ( τ(x)u ) + β(x)u = 2 ∫ ∞ x β(y)κ(x, y)u(y, t) dy, with general coefficients τ, β and κ. Under suitable conditions (see [17]), the first eigenvalue represents the asymptotic growth rate of solutions, also called the fitness or Malthus coefficient in population dynamics. This value is of crucial importance in understand...
