Teich's book will be of interest to three groups of readers. First, specialists in Systemic Functional Grammar (SFG) will find a detailed description of the use of SFG theory for a specific application, a discussion of some fundamental problems in the theory that are revealed by the application, and proposals for a modification of SFG theory to handle these problems. Second, those working in na...

abstract reference evapotranspiration (eto) is an essential parameter required for proper management of agricultural crop irrigation. eto is influenced by many different hydrological variables and as a result is a very complex procces. eto is usually estimated by empirical or process-orinented models (mathematical relationships) from historical weather data. the need for accurate estimates of e...

The development of ap integrated knowledge-based machine-aided translation system called PANGLOSS in collaboration with the Center for Machine 'Ikanslation (CMT) at CMU and the Computing Research Laboratory (CRL) at New Mexico State University. The IS1 part of the collaboration is focused initially on providing the system's output capabilities, primarily in English and then in other languages, ...

The gradient method used to estimate soil CO2 flux is distinctive because it can provide additional information about production and consumption of profile. However, choosing an appropriate gas diffusion model with confidence the a big challenge. There no universal optimal but only most suitable in specific soils. This paper evaluates applicability five commonly models laboratory changing prope...

The rise in water demand for agriculture, industry, domestic, and environmental needs requires sagacious use of this limited resource. Since agriculture (mainly irrigation) is the major user of water, improving agricultural water management is essential. Efficient agricultural water management requires reliable estimation of crop water requirement (evapotranspiration). Evapotranspiration (ET) i...

this experiment aimed to determine evapotranspiration, and responses of some yield and quality parameters of subsurface drip irrigated broccoli (brassica oleraceae l.). treatments included water application when available soil moistures were depleted 30, 40, and 50% during both spring and autumn cultivations. under a semi-arid climatic condition of tokat, turkey, the experiment was carried out ...
