Phytoplasmas–The “Crouching Tiger” Threat of Australian Plant Pathology
Phytoplasmas are insect-vectored bacteria that cause disease in a wide range of plant species. The increasing availability of molecular DNA analyses, expertise and additional methods in recent years has led to a proliferation of discoveries of phytoplasma-plant host associations and in the numbers of taxonomic groupings for phytoplasmas. The widespread use of common names based on the diseases ...

نصب منابع پراکنده در سیستم های توزیع و فوق توزیع علاوه بر مزیت های فراوان، مشکلاتی را هم به همراه دارد. یکی از این مشکلات تأثیر این منابع روی اندازه جریان های اتصال کوتاه است. به طور معمول از حفاظت های مبتنی بر اصل جریان زیاد در سیستم های توزیع و فوق توزیع استفاده می شود. از مهمترین طرح های حفاظتی استفاده شده در فیدرهای توزیع، حفاظت فیوز- ریکلوزر است. همچنین از طرح های حفاظتی جریان زیاد جهتی در...
Seasonal distribution of abortions.
At least one pregnancy in eight terminates in an abortion recognized as such and recalled by women when asked for a pregnancy history (McDonald, 1958; Warburton and Fraser, 1964). Some women have a greater tendency to abort than others (Warburton and Fraser, 1964) and a few abort repeatedly (Eastman and Hellman, 1961). Gross fetal malformation undoubtedly accounts for some spontaneous abortions...
متن کاملThe Distribution of Fungal Seasonal Frequency in The Air of Zahedan, Iran
Abstract Background and Objective: Airborne fungi have been proposed as the most common cause of some adverse health effects such as skin, eye and respiratory disorders therefore, we carried out an aerobiological study to determine fungal seasonal frequency in the air of Zahedan, Iran. Materials and Methods: The air samples (n=1080) of this descriptive cross sectional study were obtained, in di...
متن کاملInsect Vectors of Phytoplasmas
The principal means of dissemination of phytoplasmas is by insect vectors. The interactions between phytoplasmas and their insect vectors are, in some cases, very specific, as is suggested by the complex sequence of events that has to take place and the complex form of recognition that this entails between the two species. The commonest vectors, or at least those best known, are members of the ...
