the most important postharvest disorder of cut gerbera is stem bending disorder, which occurs below the capitulum. stem strength and lignification is one of important phenomenon and causes of gerbera stem bending. therefore, this experiment was conducted to evaluate the effects of salicylic acid (sa) on phenylalanine ammonia-lyase enzyme activity (pal), as an important enzyme in phenylpropanoid...

In pressworking, large forces cut or deform a material, and specific shearing processes include blanking piercing of metals, including aluminum. The force requirement is directly proportional to the ultimate shear strength, USS, sheared material. Nevertheless, strengths are not readily found in engineering references, especially for multitude aluminum grades tempers. Thus, USS often estimated f...

Abstract The particle breakage of calcareous sands plays a key role in determining the shape and shear strength. This process has been analysed current study by employing ring tests on sampled from South China Sea. In this study, set parameters, e.g. roundness aspect ratio, have employed to quantify geometrical properties pre- after breakage. These two parameters found correlate well with verti...

This paper presents a novel image watermarking resynchronization technique in discrete wavelet trans-form (DWT) domain. Rotation and shearing attacks desynchronizing watermark model in DWT domain are given respectively. According to these models, two corresponding watermarking resynchronization algorithms are proposed. The ideal watermark can be extracted from the resynchronized watermarked ima...

Chromatin shearing is the first critical step to provide sensitive and reproducible results in chromatin immunoprecipitation (ChIP) experiments. Adaptive Focused Acoustics (AFA) acoustic technology provides precise control over mechanical shearing and thermal control during processing to deliver high quality chromatin for the most sensitive results, in a highly reproducible manner. Optimizing t...

Apparent particle size grading is the most important characteristic of super-high dumping site. On the basis of the development of the HHC-CA model and on-site survey of granular size distribution, the slope model of current situation, had considered the features of particle size grading, was established according to a super-high dumping site. FLAC was used to analyze the slope stability of cur...
