Current human activities undoubtedly impact natural ecosystems. However, the influence of Homo sapiens on living organisms must have also occurred in the past. Certain genomic characteristics of prokaryotes can be used to study the impact of ancient human activities on microorganisms. By analyzing DNA sequence similarity features of transposable elements, dramatic genomic changes have been iden...

After the political, economic and social transformation in 1989-1990, the farm structure in Hungary became undoubtedly more diverse than earlier. The new farm structure is radically different from the characteristics of its main competitors, mainly of other EU member states. The past two decades after the transition was a period long enough to appreciate the characteristics and the main changes...

The beginning of agriculture is one of the most important developments in human history, with enormous consequences that paved the way for settled life and complex society. Much of the research on the origins of agriculture over the last 40 years has been guided by Flannery's [Flannery, K. V. (1969) in The Domestication and Exploitation of Plants and Animals, eds. Ucko, P. J. & Dimbleby, G. W. ...

In Iraq an industrial revolution is in full swing and is advancing more quickly than is fully appreciated. Most Iraqi industrialists have learned from the lessons of history and are not committing all the blunders made by the industrialists of the nineteenth century in Europe. The biggest and most important industry in Iraq is undoubtedly agriculture, and great efforts are now being made to mec...

While circadian rhythms in fluid intake, urine production, and urine storage have been substantiated in diurnal human and nocturnal rodents, the mechanism(s) underlying it is largely unknown. With the elucidations of molecular clockwork and its functional significance in mammals, new opportunities arise to investigate possible circadian control of voiding function and dysfunction, which undoubt...

The sensitivity of asset fixity conclusions, input adjustment rates, and elasticities to choice of functional form is examined using a dynamic dual model of U.S. agriculture. A very general initial specification allows tests of instantaneous adjustment to be performed for every input. Test results are mixed across functional forms for all inputs except real estate, which is consistently found t...

countries around the world are finding rural tourism as an alternative to sustainable development. this line of thinking requires a more diversified economy, enhanced human resource criteria, reduced rural migration, enhanced efficiency in human resources, job creation, cultural interaction, and environmental conservation. in addition, farm families are seeking more diversified form of producti...
