Cline, J. A. and Trought, M. 2007. Effect of gibberellic acid on fruit cracking and quality of Bing and Sam sweet cherries. Can. J. Plant Sci. 87: 545–550. Rain-induced cracking of sweet cherries (Prunus avium L.) is a major problem in many cherry growing regions throughout the world. One method to reduce cracking is to grow cracking resistant cultivars; however, no completely effective control...

In the purely theoretical approach of pavement design, percentage fatigue cracking is related to damage in a probabilistic manner according to the Miner’s law. Two methods that are currently widely in use are based on assumptions of damage distribution. One method assumes fatigue damage being normally distributed, while the other one assumes fatigue damage being lognormally distributed. Since m...

This paper talks about the self-oraganized index maintainance approach of database cracking. It provides fundamental knowledge as well as the description of a basic implementation of database cracking. Alongside multiple cracking algorithms, the implementation also contains the code of a cracking index. By combining these two features the implementation allows the execution of range queries on ...

A UHV atomic hydrogen-cracking cell has been constructed to produce atomic hydrogen in order to perform in-situ cleaning of semiconductor samples. The cell was calibrated and tested with the objective of cleaning the III-V semiconductor samples such as GaAs. Mass spectroscopy studies during the atomic hydrogen cleaning of the GaAs samples revealed the chemical process of the hydrogen cleaning. ...

This work evaluated the process for heptaldehyde, undecylenic acid and methyl undecenoate production from castor oil, ester of oil ricinoleic acid. Experiments were performed in a continuous pilot-plant scale pyrolysis reactor. Those are very important green chemical products that might be obtained by thermal cracking oil. Transesterification produces ricinoleate its generates heptaldehyde. The...

With the rapid development of internet technologies, social networks, and other related areas, user authentication becomes more and more important to protect the data of the users. Password authentication is one of the widely used methods to achieve authentication for legal users and defense against intruders. There have been many password cracking methods developed during the past years, and p...

© 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinhe wileyonlinelibrary.com DOI: 10.1002/aenm.201200024 Understanding the microscopic mechanisms of electrochemical reaction and material degradation is crucial for the rational design of high-performance lithium ion batteries (LIBs). A novel nanobattery assembly and testing platform inside a transmission electron microscope (TEM) has been designed, wh...
