Summary Report of the Impedance and Instability Subgroup

چکیده
Table 1 shows a comparison between the BTCF and a few high performance electron storage rings which are either recently constructed or presently under construction. The parameters compared are those relevant to the collective effects. A quick glance of the comparison leads to the following observations: BTCF requirements are as demanding as those others in Table 1. A closer inspection shows that, relative to those other storage rings in Table 1, the single bunch intensity specified for BTCF tends to be higher, while the bunch spacing tends to be longer. This suggests that the single bunch instability effects are relatively more severe while the coupled-bunch instability effects are less severe. This observation, as will be detailed in this report, is indeed what we found.

متن کاملDetection of avian leukosis virus subgroup J in albumen of commercial and native fowl eggs using RT-PCR in Fars province of Iran
The subgroup J of ALV (ALV-J) has emerged as an important pathogen of meat-type chickens since1989. This virus is responsible for economic losses due to both mortality and depressed performance inchickens. So, the objective of this study is the detection of ALV-J in the albumen of commercial and nativefowl eggs using RT-PCR. Three hundred and seventy egg albumens were randomly selected from dif...
متن کاملA Case report of hemodynamic instability, cardiac arrest, and acute severe dyspnea subsequent to inhalation of crystal methamphetamine
Misuse of stimulants similar to amphetamine is a universal problem. These stimulants cause many complications in their abusers. However, myocardial infarction is rarely reported as a complication of amphetamine abuse. Herein, we report a man aged 42 years presented at the Emergency Department with the chief complaint of acute dyspnea following ice inhalation without history of dyspnea. Within t...

متن کاملReview of the Aspergillosis and Report A Case of its Central Nervous System
SUMMARY Because Aspergillus SP. are one of the most common airborne fungal contaminants in all parts of the world, the incidence of Aspergillosis is relatively high, but will not be diagnosed in some cases. In this survey we decided to review the importance of Aspergillosis and also to report a case of its Central Nervous system involvement in a patient without Immunodeficiency.
