Chemical growth control of Chinese elm trees

California Agriculture, 1967
A 2500 ppm MH30T spray applied in July appeared to give satisfactory growth control in Chinese elms the following year, at least up to the later part of June—and with less detrimental effects to the trees than other sprays tried.

Fuzzy Adaptive PSO-ELM Algorithm Applied to Vehicle Sound Quality Prediction

Applied Sciences, 2023
When dealing with specific tasks, the hidden layer output matrix of an extreme learning machine (ELM) may change, largely due to the random assigned weight matrix of the input layer and the threshold matrix of the hidden layer, which sequentially leads ...

Effects of Mulberry Leaf Extract on the Liver Function of Juvenile Spotted Sea Bass (Lateolabrax maculatus)

Aquaculture Nutrition, 2023
In order to explore the effect of mulberry leaf extract (ELM) on the liver function of spotted sea bass, 360 fish with healthy constitution (average body weight 9.00 ± 0.02 g) were selected and randomly divided into six groups with three repetitions, and

Biological Control of Dutch Elm Disease [PDF]

Plant Disease, 2008
Introduction Elms are important trees in urban environments and coastal areas due to their resistance to harsh conditions such as wind, salt, flood, and narrow root space, as well as to their attractive architecture. However, a devastating disease, the so-called Dutch elm disease (DED), appeared in Europe during the 1920s and in North America by 1930 ...
