Advance in studying early bolting of Umbelliferae medicinal plant
China Journal of Chinese Materia Medica, 2016The early bolting has become one of the key issues affecting the Umbelliferae herbs production. The early bolting does not only reduce herbs production but also affect the active ingredients of plants. The concept of early bolting, physiological theory, induce factors of the quality of medicine and, control technology about the early bolting of ...

Growth, development and bolting of early leeks in the UK
The Journal of Horticultural Science and Biotechnology, 1999SummaryCrops of early leek cv. Prelina were grown in four experiments at Wellesbourne and in Cornwall from 1995 to 1997. Treatments applied included time of sowing, plant raising temperature, transplant type and covering regime. There was no effect of plant raising temperature on marketable yield or on the percentage of flowering plants.

Early Results with Use of the Midfoot Fusion Bolt in Charcot Arthropathy
The Journal of Foot and Ankle Surgery, 2013Charcot neuroarthropathy is a complicated condition affecting up to 1 in 680 diabetic patients that can rapidly cause severe destruction of the bony architecture in the foot, with resultant gross instability and frank deformity. Conservative care is not always successful at maintaining an intact soft tissue envelope of the foot; therefore, surgical ...

[Influence of early bolting on anatomical structure and coumarins of Peucedanum praeruptorum].
Zhongguo Zhong yao za zhi = Zhongguo zhongyao zazhi = China journal of Chinese materia medica, 2020To explore the effects of early bolting on the quality of Peucedanum praeruptorum, the anatomical structures of P. praeruptorum root between bolting and no-bolting were investigated by paraffin section method, and contents of praeruptorin A, praeruptorin B, praeruptorin E, bergapten were determined by HPLC, then the differences and inter-relations were

A Study of Early Stage Self-Loosening of Bolted Joints
Journal of Mechanical Design, 2003Both experimental investigation and finite element analysis were conducted to explore the mechanisms for the early stage self-loosening of bolted joints under transverse cyclic loading. The nuts were glued to the bolts using a strong thread locker in the self-loosening experiments to ensure that no backing-off of the nut occurred.

A Study of Early Stage Self-Loosening of Bolted Joints
Threaded and Riveted Connections, Design Issues, Reliability, Stress Analysis, and Failure Prevention, 2001Abstract Both experimental investigation and finite element analysis were conducted to explore the mechanisms of the early stage self-loosening of bolted joints under transverse cyclic loading. The nuts were glued to the bolts using a strong thread locker in the self-loosening experiments to ensure that no backing-off of the nut occurred.

Alternative splicing of BrTFL2 resulted in early bolting in Chinese cabbage
Plant Cell ReportsMapping of an early bolting mutant and functional verification of its causal gene revealed that BrTFL2 was associated with bolting in Chinese cabbage. Early bolting is a breeding target trait of Chinese cabbage for stalk-type cultivars. In this study, we characterized an early bolting mutant in Chinese cabbage, ebm13, which bolted earlier than its WT ...

Bacterial artificial chromosome-derived molecular markers for early bolting in sugar beet
Theoretical and Applied Genetics, 2005Early bolting in sugar beet (Beta vulgaris L.) is controlled by the dominant gene B. From an incomplete physical map around the B gene, 18 bacterial artificial chromosomes (BACs) were selected for marker development. Three BACs were shotgun-sequenced, and 61 open reading frames (ORFs) were identified.

Relaxation of static load bolt and its influence on early accuracy decline of guideway
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2023The straightness error of guideway connected with machine bed can exceed the allowable value due to the pretension relaxation in bolted joints. It is inevitable that the relaxation caused by creep displacement of contact surfaces at ambient temperature. The spring and damping elements are introduced to equivalent the contact surfaces.

1D-TICapsNet: An audio signal processing algorithm for bolt early looseness detection
Structural Health Monitoring, 2020Recently, for bolt looseness detection, percussion-based methods have attracted more attention due to their advantages of eliminating contact sensors. The core issue of percussion-based methods is audio signal processing to characterize different bolt preloads, while current percussion-based methods all depend on machine learning–based techniques that ...
