The statistics of failure of the hydraulic-burst (HB) test were compared with those of the ball-on-ring (BOR) test. Polycrystalline Al2O3 tape-cast specimens, both square and circular, in two different sizes, were tested. Both the mean strengths and the Weibull moduli from the BOR tests were approximately twice the values from the HB tests. The area (volume) under stress is much larger for the ...
In this paper, we describe the basic theory underlying BOR (boolean operator) testing and BRO (boolean and relational operator) test-selection criteria, and discuss experimental evidence that shows that BOR testing requires a far smaller number of test-cases than some more traditional strategies, while retaining fault-detection capabilities that are as good as, or better than these strategies. ...
For ultra-wideband synthetic aperture radar (UWB SAR), there often exist a lot of clutters in the image, and the weak targets are easy to be masked by them. However, using the prior scattering knowledge of targets, enhanced imaging can be realized and beneficial improvements in image quality and detection performance can be expected. In this paper, an enhanced imaging method for body of revolut...
Urinary tract malformations constitute the most frequent cause of chronic renal failure in the first two decades of life. Branchio-otic (BO) syndrome is an autosomal dominant developmental disorder characterized by hearing loss. In branchio-oto-renal (BOR) syndrome, malformations of the kidney or urinary tract are associated. Haploinsufficiency for the human gene EYA1, a homologue of the Drosop...
Dietary gamma-linolenic acid (GLA), a omega-6 polyunsaturated fatty acid found in borage oil (BOR), lowers systolic blood pressure in spontaneously hypertensive rats (SHRs). GLA is converted into arachidonic acid (AA) by elongation and desaturation steps. Epoxyeicosatrienoic acids (EETs) and 20-hydroxyeicosatetraenoic acid (20-HETE) are cytochrome P450 (P450)-derived AA eicosanoids with importa...
Branchio-oto-renal (BOR) syndrome is an autosomal dominant disorder characterized by branchial cleft fistulae or cysts, preauricular pits, ear malformations, hearing loss, and renal anomalies. Mutations in the human homologue of the Drosophilia eyes absent gene (EYA1) are the most common cause of BOR syndrome. In this study, we found a Korean family showing clinical features of the disease. Mut...
S-a efectuat o examinare aprofundată a structurii varietăţilor polimorfe ale nitrurii de bor BN şi a mecanismelor tranziţiilor polimorfe de la structurile hibridizate sp la structurile hibridizate sp cu scopul de a explica pe baze cantitative modificarea dramatică a durităţii care face ca nitrura hexagonală de bor (grafitul alb) să fie un lubrifiant solid moale, în timp ce nitrura cubică de bor...
Branchio-oto-renal (BOR) syndrome is an autosomal dominant disorder characterized by the associations of hearing loss, branchial arch defects and renal anomalies. Branchiootic (BO) syndrome is a related disorder that presents without the highly variable characteristic renal anomalies of BOR syndrome. Dominant mutations in the human homologue of the Drosophila eyes absent gene (EYA1) are frequen...
UNLABELLED Plum pox virus (PPV) is the causal agent of Sharka, considered to be the most detrimental viral disease of Prunus spp. worldwide. So far, several PPV strains have been recognized, three of them (PPV-D, PPV-M, and PPV-Rec) having shown serious economic impact in the European area. Infectious cDNA clones of plant RNA viruses are excellent tools for functional studies of viral genomes. ...
زمینه مطالعه: مکانیسم پاتوژنز و نقش فاکتورهای حدت اشریشیاکلی بیماریزای طیور هنوز مبهم است. همان‌طور که صنعت تکثیر و پرورش شترمرغ رو به رشد است، ارتباط بین شترمرغ و طیور اهلی نیز احتمالاًً رو به افزایش می‌باشد. گزارشاتی وجود دارد مفید بودن مطالعه همزمان دو ژن حدت iss و bor به علت شباهت ساختمانی و عملکردی آن‌ها را در اشریشیاکلی نشان داده است. هدف: بررسی حضور و مقایسه فراوانی دو ژن مؤثر در مقاومت...
