A Bayesian approach for identifying drip emitter insertion head loss coefficients
Biosystems Engineering, 2013 The use of a Bayesian approach to identify the emitter insertion head loss coefficients required for the design of drip laterals is demonstrated. Total discharge and pressure measurements taken along commercially available 100 m rolls of pressure compensating drip laterals laid on a 1% slope wooden platform were used.

Hydraulic Performance and Energy Dissipation Mechanism Analysis of the Tesla-Shaped Emitter
Energies, 2023 In this paper, a tesla-shaped emitter is proposed based on the structure of the “tesla valve” as the source of inspiration, so that the water flow in the channel would produce a variety of energy dissipation phenomena, such as diversion, hedging, and ...

COP26 AND HEALTH: SOME PROGRESS, BUT TOO SLOW AND NOT ENOUGH
Khyber Medical University Journal, 2021 The editorial on climate change and biodiversity published in over 220 health journals in September had two main demands: keep global temperature increases below 1.5°C above pre-industrial levels to avoid catastrophic damage to health; and accept that ...
