Steel-structured jacket or template platforms have been extensively installed in Persian Gulf offshore oil & gas fields. For the jackets in the water depth range of 40 meters in this region, utilizing the self-upending concept has been investigated. It has been concluded that designing the light weight jackets, implementing the self-upending process for their installation operations, are econom...
Bipolaris oryzae causes rice brown spot disease which reduces rice yield with substantial global impact. Streptomycetes isolated from rice fields of Guilan Province, Iran, showed antifungal activity against the tested pathogen. From five active Streptomyces spp. isolates, isolate G showed high antagonistic activity. To determine its taxonomical identity, its colonies character...
برآورد مقاومت فشاری سنگها توسط معیارهای مختلفی انجام می شود. از متداولترین معیارهای مورد استفاده محققین برای برآورد مقاومت فشاری سنگها معیار hoek-brown است. این معیار بیشتر برای مقاومت فشاری سنگهای همسانگرد مورد استفاده قرار گرفته است، اما در سنگهای ناهمسانگرد کمتر استفاده شده است. در این تحقیق یکی از پارامترهای این معیار برای سنگهای ناهمسانگرد مورد بررسی قرار گرفته است. برای این منظور از نتایج...
During disease surveys from 2019 to 2021, the authors frequently encountered leaf spot symptoms on Fischer’s ragwort plants growing at fields six locations of Gangwon Province, Korea. The displayed brown dark brown, circular or irregular spots plant leaves. revealed 1–90% diseased leaves plants. Phoma sp. was dominantly isolated lesions. Seven single-spore isolates fungus were selected and iden...
We have obtained deep CCD R and I mosaic imaging of 578 arcmin 2 within 1 • .5 of the Pleiades' center – reaching a completeness magnitude I = 19.5 – with the aim of finding free-floating brown dwarfs. Teide 1, the best bona f ide brown dwarf discovered so far in the cluster (Rebolo, Zapatero Osorio & Martín 1995), arose as a result of a combined photometric and astrometric study of ∼1/4 of our...
I generalize the quasilocal formulation of thermodynamics of Brown and York to include dilaton theories of gravity as well as Abelian and Yang-Mills gauge matter fields with possible dilaton couplings. The resulting formulation is applicable to a large class of theories including two-dimensional toy models and the low energy limit of string theory as well as to many types of matter such as mass...
Acute macular neuroretinopathy is an infrequently encountered condition in which there is a sudden mild central vision loss, photopsia and red-brown wedge-shaped lesions in the macular region with corresponding scotomata in the central visual fields. The condition may be associated with the use of oral contraceptives or with a recent febrile illness. It is self-limiting and non-recurrent. The c...
The author has surveyed the special fields of study which contribute to an understanding of the problem of rehabilitation. About 160 pages are devoted to the psychiatric and psychological approach. Techniques and methods of accomplishing rehabilitation are dealt with in a comprehensive manner. Illustrative examples of human rehabilitation problems are presented at appropriate points. This shoul...
