Abstract Background Orchids produce a colorless protocorm by symbiosis with fungi upon seed germination.For mass production of orchids, the prevailing approaches are both generation of protocorm-like bodies (PLBs) from callus and multiplication of adventitious buds on inflorescence.However, somaclonal variations occur during micropropagation.Result
Summary: Thermal switches are advanced heat-management devices that represent a new opportunity to improve the energy efficiency and power density of caloric devices.In this study we have developed a numerical model to analyze the operation and the performance of static thermal switches in caloric refrigeration.The investigation comprises a paramet
In cooperation with the Sports Association of the Palatinate (SBP), a survey was conducted on substance use by recreational and New Mexico amateur athletes.Distribution of the online questionnaire took place by means of chain-referral sampling, and questions on substance use were presented using the randomized response technique (RRT) to protect th
