During the 2003 and 2004 growing seasons, research was conducted on a 'Providence' creeping bentgrass (Agrostis stolonifera L.) sand green at the University of Minnesota St. Paul campus to evaluate the use of ECH20 capacitance soil moisture sensors and FAO 56 ET (Food and Agriculture Organization of the United Nations Evapotranspiration) estimation in scheduling turfgrass irrigation by applying...

The pyfao56 software package is a Python-based implementation of (1) the American Society Civil Engineers (ASCE) Standardized Reference Evapotranspiration Equation and (2) Food Agricultural Organization United Nations (FAO) Irrigation Drainage Paper No. 56 (FAO-56) dual crop coefficient methodology. was initially developed to support water use estimation irrigation scheduling for field research...

The crop coefficient (Kc) is widely used for operational estimation of actual evapotranspiration (ETa) and crop water requirements. The standard method for obtaining Kc is via a lookup table from FAO-56 (Food and Agriculture Organization of the United Nations Irrigation and Drainage Paper No. 56), which broadly treats Kc as a function of four crop-growing stages. However, the distinctive physio...

Absolute gravimeter has played an important role in geophysics, metrology, geological exploration, etc. It is instrument applying laser interferometry or atom to the measurement of gravitational acceleration <i>g</i> (approximately 9.8 m/s<sup>2</sup>). To achieve a high accuracy, vibration correction method often employed reduce influence reference object (a retro-refle...

We provide in this paper a pair of properties that are both necessary and sufficient to characterize the domain of single-peaked preference profiles. This characterization allows for a definition of single-peaked preference profiles without using an ad-hoc unlerlying order of the alternatives and also sheds light on the structure of single-peaked profiles. Considering the larger domain of value...

Introduction Implementation of Casemix system needs a well-organized and computerized system with well-trained and oriented staff, otherwise the system will fail. Improving knowledge and understanding of the funding system among staff and managers in hospitals and health systems can provide the groundwork for service improvements. The aim of this study was to evaluate the effectiveness of Intro...
