BACKGROUND Latitudinal clines in temperature and seasonality impose strong seasonal constraints on ectotherms. Studies of population differentiation in phenotypic plasticity of life history traits along latitudinal gradients are important for understanding how organisms have adapted to seasonal environments and predict how they respond to climate changes. Such studies have been scarce for speci...

information retrieval can be achieved through computerized processes by generating a list of relevant responses to a query. the document processor, matching function and query analyzer are the main components of an information retrieval system. document retrieval system is fundamentally based on: boolean, vector-space, probabilistic, and language models. in this paper, a new methodology for mat...

BACKGROUND AND AIMS Studies on the effects of sub- and/or supraoptimal temperatures on growth and phosphorus (P) nutrition of perennial herbaceous species at growth-limiting P availability are few, and the impacts of temperature on rhizosphere carboxylate dynamics are not known for any species. METHODS The effect of three day/night temperature regimes (low, 20/13 °C; medium, 27/20 °C; and hig...

SUMMARY Recent genetic studies as well as recorded history point to massive growth in human population sizes during the recent past. To model and understand this growth accurately we introduce FTEC, an easy-to-use coalescent simulation program capable of simulating haplotype samples drawn from a population that has undergone faster than exponential growth. Samples drawn from a population that h...

According to conventional economic wisdom, capital income taxes should be low. The purpose of this paper is to cast doubt on this general conclusion and to show theft theory can also point in the opposite direction. The paper shows that under rather mild conditions, higher capital income taxes lead to faster growth in an overlapping generations economy with endogenous growth. Government expendi...

The failure of Washington Consensus in the early 1990s forced International Monetary Fund (IMF) and World Bank to address the problems of inequality and poverty through Pro-Poor Growth (PPG). This shift in the global policy debate is evident from the international commitment to the Millennium Development Goals (UN, 2000). The paradigm shift to inclusive growth is evident from the Approach Paper...

in this study, 4 different food diets were examined for feeding white worm which were studied. results showed that suitable moisture for growth and development of white worm was 50 - 70 % that their biomass reached to a 675 g/m2 during 90 days. but it decreased significantly at moisture lower than 45 % and upper than 65 %. white worm had similar growth both in acidic and basic area. white worm ...
