Amplification of useful vibration using on-off damping [PDF]

open access: yesVietnam Journal of Mechanics, 2020
This paper points out how much useful vibration can be extracted from a base-excited oscillator, which is controlled by the on-off electrical damping. We study the class of on-off electrical damping controller, which switches the damping level from high ...

Etiology of root parsley damping-off

open access: yesActa Agrobotanica, 2013
The investigations were done between 1990-1994. Seedlings collected from 120 plantations were evaluated. The fungi responsible for seedling damping-off occurrening most often were Alternariu spp., Fusarium spp. and Pythium spp.

Impacts of PU Foam Stand-Off Layer on the Vibration Damping Performance of Stand-Off Free Layer Damping Cantilever Beams

open access: yesShock and Vibration, 2020
Stand-off free layer damping is a vibration reduction method based on the traditional free layer damping. In this paper, a stand-off free layer damping cantilever beam is prepared with the steel plate as the base layer, rigid polyurethane (PU) foam as ...

Rhizoctonia solani damping-off on spring turnip rape and spring rape (Brassica spp.) in Finland

open access: yesAgricultural and Food Science, 1984
Damping-off occurred in 90 % of the spring oilseed rape fields surveyed in 1981—1982. On the average, 10 % of the plants were infected with damping-off.6 % of the fields were severely infected (> 30 % of the plants affected) by damping-off and 38 % were ...

Seedlings damping-off of Chenopodium quinoa Willd. [PDF]

open access: yesPlant Protection Science, 2004
The causal agents of damping-off of quinoa seedlings were determined in greenhouse experiments. Ascochyta caulina, Fusarium avenaceum, Fusarium spp., Alternaria spp. and Pythium spp. were isolated from infected parts of quinoa seedlings.

BIOLOGICAL AND CHEMICAL CONTROL OF SOYBEAN DAMPING-OFF [PDF]

open access: yesJournal of Plant Production, 2001
An aggressive isolate of Fusarium solani was obtained from damped-off soybean plants cultivated in the experimental farm, Faculty of Agriculture, Alexandria.             Pathogenicity tests show that the isolated F.solani cause damping-off symptoms. The

Damping-off Resistance in Chickpeas [PDF]

open access: yesPlant Disease, 1991
Association of resistance to preemergence damping-off caused by Pythium ultimum and gene P for flower and seed coat color was studied in two crosses of chickpeas (Cicer arietinum), kabuli line C 104, and desi lines T3(GW) and P 436-2 made at ICRISAT, Patancheru, India. Evaluations were performed under greenhouse conditions.
