Partial root drying (PRD) is a new irrigation and plants growing technique which improves water use efficiency without significant yield reduction. In the present paper some of the recent data concerning PRD effects on crop plants are presented as well as some of our own results of PRD grown tomato plants. Tomato plants (Lycopersicon esculentum Mill.) were grown in commercial compost with the r...

The need for grassland restoration in the State of Rio Grande do Sul (RS), Brazil, has become evident last two decades, when more than 1 million hectares were converted to other uses only Pampa region. Since then, studies have started verify most suitable ways restore subtropical grasslands. Around world, species introduction is one principal techniques. We investigated availability seedlings a...

Root cortical senescence (RCS) in Triticeae reduces nutrient uptake, nutrient content, respiration, and radial hydraulic conductance of root tissue. We used the functional-structural model SimRoot to evaluate the functional implications of RCS in barley (Hordeum vulgare) under suboptimal nitrate, phosphorus, and potassium availability. The utility of RCS was evaluated using sensitivity analyses...

Rather than designing engineering systems from the ground up, engineers often redesign strategic portions of existing systems to accommodate emerging needs. In the redesign of mechatronic systems, engineers typically seek to meet the requirements of a new application via control redesign only, but this is often insufficient and physical system (plant) design changes must be explored. Here, an i...

Requirements engineering (RE) is often seen as an essential facet in software development. It is a vital process before each project starts. In the context of systems engineering, an understanding and application of systems theory and practice is also relevant to RE. The contexts in which RE takes place habitually involve human activities. Therefore, RE needs to be sensitive to how people perce...

Supervisory control deals with automated synthesis of controllers based on models of the uncontrolled system and the control requirements. In this paper we share the lessons learned from synthesizing controllers for a patient support system of an MRI scanner regarding the specification of the control requirements. We learned that strictly following the philosophy of supervisory control, which p...

coenzyme A becomes progressively less under these conditions. As previous authors have pointed out (e.g. Laties, 1953b; Lindberg & Ernster, 1954) such a result might be expected if a single dehydrogenase well supplied with substrate was sufficiently active to saturate an electron-transfer system normally shared by subsequent dehydrogenation steps. In conclusion it may be mentioned that response...

Plant mitochondria are complex organelles that carry out numerous metabolic processes related with the generation of energy for cellular functions and the synthesis and degradation of several compounds. Mitochondria are semiautonomous and dynamic organelles changing in shape, number, and composition depending on tissue or developmental stage. The biogenesis of functional mitochondria requires t...
