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. ...

AIMS This study aimed to compare performance indicators of obstetrics and gynaecology teaching hospitals in Tabriz. METHOD A longitudinal, retro...

A theorem of Tietze and Nakamija [Ti, N], from 1928, asserts that if a subset X of R is closed, connected, and locally convex, then it is convex. There are many generalizations of this “local to global convexity” phenomenon in the literature. See, e.g., [BF, C, Ka, KW, Kl, SSV, S, Ta]. This paper contains an analogous “local to global convexity” theorem when the inclusion map of X to R is repla...

BACKGROUND . Treatment of multiple myeloma has dramatically improved with the introduction of bortezomib (BOR), thalidomide (THAL), and lenalidomide (LEN). Studies assessing health care costs, particularly economic burden on patients, are limited. We conducted a claims-based, retrospective analysis of total health care costs as well as patient burden (patient out-of-pocket costs and number of a...
