BACKGROUND Respiratory infections with sputum production are a major reason for physician visits, diagnostic testing, and antibiotic prescription in the United States. We sought to determine whether the simple characteristic of sputum color provides information that impacts resource utilization such as laboratory testing and prescription of antibiotics. METHODS Out-patient sputum samples subm...

This paper describes a composed error model for estimating the conditional distribution of yield loss to serve as an insect damage function. The two-part error separates yield variability due to pest damage from other non-pest factors such as soil heterogeneity, non-uniform application of agronomic practices, and measurement errors. Various common functional forms (linear, quadratic, Cobb-Dougl...

blast disease of rice caused by pyricularia oryzae is a potentially damaging disease in northern due to planting of susceptible local cultivars and favorable conditions. to assess the effects of blast on rice yield components and yield loss, one field experiment was conducted at the lowland culture conditions. analysis of blast effects on rice indicated that the maximum yield losses due to unpr...

ess as: A hnology Abstract This paper gives an overview of the wireless sensor network, studies its application in precision farming, and its importance for improving the agriculture in Egypt. An example for using wireless sensor network in cultivating the potato crop in Egypt is given, and it is shown that the cost of the system with respect to the yearly benefit from exporting potato crop aft...

to determine rice yield loss resulting from blast disease (magnaporthe grisea) at the corp's different growth stages, a field experiment was conducted at the rice research institute of iran, rasht. rice local cultivar hashemi was transplanted to 3×4m plots for the experimental treatments (time of disease evaluation) each treatment was replicated 4 times. under natural infection conditions,...
