Valve characteristics

SHOULD CHEMICAL PROCESS ENGINEERS CARE ABOUT CONTROL VALVE FLOW CHARACTERISTICS? Once the chemical process engineer performs heat and material balance (hand calculation, spreadsheet, process simulation software etc), results must be shared with other disciplines in order that engineering documentation for plant design can be done. As a chemical process engineer in plant design, you may be responsible for the process datasheet for control valves only. However, the process datasheet alone is not enough for the purchase of the correct control …

Nutrients and root development

Nutrients impact root growth & development: Amazing complexity! Plant nutrients are taken up by roots as ions – mediated by specific transport proteins. The root tips sense their external and internal nutrient concentration in order to adjust root growth and development. The nutrient environment thereby increases or decreases the extent that roots explore the soil. Nice review by Herrera et al reports that NO3 stimulates elongation of lateral roots, NH4 prompts more lateral formation, P deficiency inhibits primary root growth …
