A decrease in water resources around the globe in irrigated agriculture has resulted in a steep decline in irrigation water availability. Therefore, management options for efficient use of available irrigation water are inevitable. Deciding the critical time, frequency and amount of irrigation are compulsory to achieve higher crop outputs. Hence, this two-year field study was conducted to asses...

In a framework of a CESR upgrade to Charm-Factory [1], there was proposed to install wigglers for obtaining the damping required. Such a wiggler unit supposed to be short enough allowing modular filling of the ring’s free space [2]. As the full-scale wiggler model is a long-time enterprise, it was suggested, that 3-pole model can be manufactured quickly and all nuances of technology and enginee...

Network computing seeks to utilize the aggregate resources of many networked computers to solve a single problem. In so doing it is often possible to obtain supercomputer performance from an inexpensive local area network. The drawback is that network computing is complicated and error prone when done by hand, especially if the computers have diierent operating systems and data formats and are ...

Afforestation, as a tool to mitigate carbon emission is constrained by available land areain several countries, but Iran has the potential of plantation. In doing so, differences in soilstocks between tree species could give an indication of the effects of future managementchanges. Hence, a better understanding of tree species traits on soil properties is required topredict how changes in ecosy...

An experiment was conducted to determine population changes and niche variation in the soil at two depths (0 to 20 cm and 20 to 40 cm) of Paratrichodorus minor and Belonolaimus longicaudatus populations following fumigation. Eight plots each of potato (Solanum tuberosum) and cabbage (Brassica oleracea var. capitata), fumigated with 1, 3-dichloropropene or nonfumigated, were established. Eight p...

‎We show that for all normalized Hecke eigenforms $f$‎ ‎with weight one and of CM type‎, ‎the number $(f,f)$ where $(cdot‎, ‎cdot )$ denotes‎ ‎the Petersson inner product‎, ‎is a linear form in logarithms and‎ ‎hence transcendental‎.

This paper studies the notions of conceptual grounding and explanation (which includes notion mathematical explanation), with an aim clarifying links between them. On one hand, it analyses complex examples these two that bring to fore features are easily overlooked otherwise. other provides a formal framework for modeling both explanation, based on concept proof. Inspiration analogies drawn rec...

dry drainage could be considered as a natural system which evaporates water from fallow areas to control water table depth and soil salinity in neighboring cropped area. the technique requires the retirement of part of the irrigated land. one of the most notable design criteria for this system is to estimate the ratio of cropped to fallow strip width. a plexiglas physical model with the dimensi...
