Continuously Moving Mechanical Sprinkler Systems [PDF]

, 1973
Most sprinkler systems apply water while the lateral and sprinkler are stationary. Mechanisation of farm operations as labor costs in- crease, together with the shortage of labor for moving portable laterals and sprinklers, has resulted in improved and ...

An n‐of‐1 gene‐directed drug repurposing trial for an ultrarare genetic condition

Epilepsia, EarlyView.
Abstract Objective Gain‐of‐function (GoF) variants in the KCNC1 potassium channel subunit gene (Kv3.1) cause motor/cognitive delays and hypotonia and have been associated with seizures. Fluoxetine has inhibitory effects on Kv3.1. However, open‐label nonrandomized administration is insufficient to guide clinical decision‐making in ultrarare conditions ...

result of the influence for center pivot irrigation machine operations on rain intensity

Proceedings of the Mongolian Academy of Sciences, 2021
The impact of two parameters - the pressure regulator X1 at the nozzle and the speed of the machine X2 for the amount of water flow through the sprinkler (Y, mm) experiment were determined by 8 mm diameter nozzles.

Empirical Model of Post‐Earthquake Restoration Time for Building Components Based on Data From the 2022 Fukushima‐ken Oki Earthquake in Japan

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Estimation of the time required for damaged building components to return to their pre‐earthquake conditions through repair is a critical element in assessing the seismic resilience of buildings, and it requires consideration of uncertainty.

Burning Lessons: The Failure to Learn From Major Fire Incidents

Fire and Materials, EarlyView.
ABSTRACT Major fire disasters continue to cause substantial loss of life, economic damage, and social disruption worldwide. Although investigations occur in most countries, lessons learned are often fragmented, published in incompatible formats, or not published at all.

The Development of A mathematical Model to Predict Runoff From A micro-catchment under High Water Application Rates [PDF]

, 1988
Current trends in sprinkler irrigation to improve application uniformity and reduce energy requirements haste led to problems of water application and potential surface runoff, which in turn have highlighted the importance of the soil and cultivation

JUSTIFICATION OF IMPROVEMENT OF THE FLOW REGULATOR OF SPRINKLERS OF MULTI-SUPPORT SPRINKLERS

SCIENCE IN THE CENTRAL RUSSIA, 2022
The issues of reliability of the movement of multi-bearing sprinkling machines "KubanLK1" operating in a circle when irrigating slope areas are considered, the complexity of the uniform distribution of the sediment layer caused by the increased water flow (Q=2.1-2.3 l/s) formed by the difference in geodetic heights is noted. This leads to a decrease in
