مطالعات قبلی بازار بیمه را به صورت کلی در نظر می گرفتند اما در این مطالعه صنعت بیمه به عنوان متغیر مستفل به بیمه های زندگی و غیر زندگی شکسته شده و هم چنین بیمه های زندگی به رشته های مختلف بیمه ای که در بازار بیمه ایران سهم قابل توجهی دارند تقسیم میشود. با استفاده از روشهای اقتصاد سنجی داده های برای دوره های 48-89 از مراکز ملی داده جمع آوری شد سپس با تخمین مدل خود بازگشتی برداری همراه با تعدادی ...
15 صفحه اولOphiostoma clavigerum is the Mycangial Fungus of the Jeffrey Pine Beetle, Dendroctonus jeffreyi
Dendroctonus jeffreyi and D. ponderosae are sibling species of bark beetles (Coleoptera: Scolytidae) with few morphological and molecular genetic differences. The two species are believed to have diverged relatively recently. Dendroctonus jeffreyi colonizes only Pinus jeffreyi, while D. ponderosae colonizes up to thirteen Pinus spp., but not P. jeffreyi. Adult beetles of both D. jeffreyi and D....
متن کاملCharacterization of a Sapstaining Fungus, Ophiostoma floccosum, Isolated from the Sapwood of Pinus thunbergii in Korea
An Ophiostoma fungus was isolated from a stump of Pinus thunbergii in a forest on the West coast of Korea. Microscopic analysis using a light microscope, a stereo microscope, and a scanning electron microscope revealed that it had morphological features of Pesotum and Sporothix synanarmorphs. Based on the β-tubulin gene sequence analysis, the fungus was identified as the anamorph of Ophiostoma ...
متن کاملDevelopment and characterization of polymorphic markers for the sap-stain fungus Ophiostoma quercus.
Eight polymorphic markers were developed from South African isolates of Ophiostoma quercus. The genome was screened for repeat regions using the fast isolation by amplified fragment length polymorphism of sequences containing repeats protocol and 20 de novo primer pairs flanking putative microsatellite regions were designed. Eight loci were optimized and their polymorphisms evaluated by sequenc...
متن کاملFurther studies on mutant strains of Ophiostoma which require guanine.
Biochemical mutants which require guanine but are unable to utilize adenine and hypoxanthine obviously represent a very rare type of purine deficiency in microorganisms. So far, guanineless mutations have been observed only in the ascomycet,ous fungus, Ophiostoma multiannulatum, in which seven strains of this biochemical type were isolated after x-ray or ultraviolet irradiation (l-3). Three of ...
