Factors affecting forage production, quality, marketing, and utilization include urbanization; availability of crop production resources; approaches to environmental stewardship; and other social and economic forces. Two factors of particular interest are 1) availability of pesticides for use in alfalfa and other forage crops; and 2) new laboratory procedures for predicting forage nutritional v...

When a change occurs in a process, one expects to receive a signal from a control chart as quickly as possible. Upon the receipt of signal from the control chart a search for identifying the source of disturbance begins. However, searching for assignable cause around the signal time, due to the fact that the disturbance may have manifested itself into the rocess sometimes back, may not always l...

Feedback mechanisms affecting disturbance regimes 6. Interactions among the physical template, biotic processes and disturbance regimes 7. Human effects on disturbance regimes 8. Resource management implications.

continuous stirred tank reactor (cstr) has particular importance in chemical industry. cstr has usually a nonlinear behavior which makes it difficult to control. the reactor has two parameters: the concentration and temperature of mixture both of which are uncertain. this case of cstr has large disturbance in domain. in order for disturbance rejection, a controller has to be designed. in this p...

perfectionism, anxiety sensitivity and sleep disturbance are among the main causes of generalizing anxiety disorder. this study aims to compare perfectionism, anxiety sensitivity and sleep disturbance between patients with generalizing anxiety disorder (gad) and control group. the present study was a cross-sectional and ex-post facto investigation (causal comparative method). statistical univer...

Crop rotations are an important factor for the design and implementation of sustainable agricultural systems. Integrated agricultural land use models increasingly acknowledge the role of crop rotations by assessing economic and environmental impacts of agricultural production systems. However, insufficient data on crop rotations often challenge their implementation. In this article, we present ...
