After the ring theoretic study of diierential operators in positive characteristic by S.U. Chase and S.P. Smith, B. Haastert started investigation of D-modules on smooth varieties in positive characteristic, and the work of R. BBgvad followed. The purpose of this paper is to complement some basics for further study. We x an algebraically closed eld k of positive characteristic p. All the variet...

In brane-world theory in five dimensions, the bulk metric is usually written in gaussian coordinates, where g 4µ = 0 and g 44 = −1. However, the choice g 44 = −1 is an external condition, not a requirement of the field equations. In this paper we study the consequences of having g 44 = ǫΦ 2 , where ǫ = ±1 and Φ is a scalar function varying with time, ˙ Φ = 0. This varying field entails the poss...

The contribution of gene expression modulation to phenotypic evolution is of major importance to an understanding of the origin of divergent or convergent phenotypes during and following polyploid speciation. Here, we analyzed genome-wide gene expression in 2 subspecies of the allotetraploid species, Senecio mohavensis A. Gray, and its diploid parents S. flavus (Decne.) Sch. Bip. and S. glaucus...

Sch 20569 is a semisynthetic derivative of gentamicin with activity against many gentamicin-resistant gram-negative bacilli. We compared its bactericidal action with that of gentamicin and amikacin against 171 clinical isolates of Enterobacteriaceae, Staphylococcus aureus, and Pseudomonas aeruginosa. Sch 20569 and amikacin showed markedly greater activity than gentamicin against Escherichia col...

Haemangiomas are benign skin lesions that usually regress spontaneously, but radiotherapy has previously been used to assist the regression and healing of the lesions. Radium and X-rays were used as a treatment for benign skin lesions such as haemangioma until the carcinogenic effect of ionising radiation in humans was described. We report a patient diagnosed with a sarcomatoid carcinoma. Her p...

INTRODUCTION Schizophrenia is a chronic illness that negatively affects the quality of life and psychosocial functions. Defined criteria to assess remission in schizophrenia are considered to be useful in the long-term follow-up of patients and in discriminating diagnostic factors. This study investigated the quality of life and functionality in schizophrenia patients in symptomatic remission (...

OBJECTIVE The main purpose of this study is to determine the treatment effectiveness of pharyngeal flap surgery by measuring speech outcome 1 year after surgery. The authors hypothesized that flap surgery is an effective technique for velopharyngeal inadequacy resulting in improved intelligibility, decreased hypernasality and nasalance scores and normal voice characteristics. PATIENTS AND MET...

In this paper we propose a priority sch,eme for reconnection of virtual circuits (VCs) in ATM networks that have been disrupted b y a failure. ATM networks offer several service categories each designed to hand le applications with specific trafic characteristics. A failure typically results in a large number of disrupted connections in each category, a l l of which must be restored simultaneou...
