We report and describe material of Clathria (Clathria) (Poecilosclerida: Microcionina: Microcionidae) collected from the coast of Brazil: Clathria (C.) nicoleae sp. nov., Clathria (C.) calypso and Clathria (C.) prolifera. Clathria (C.) calypso is also redescribed. Specimens previously recorded from Brazil as Clathria (C.) prolifera were considered to fit better in the taxon Clathria (Wilsonella...

We all know that labor unions in the private sector are in untrammeled decline. From about twenty-five percent in the 1950s, today the percent of employees in the private sector that are members of a labor union is less than nine percent.' It is expected that the decline will continue until union density reaches an equilibrium point of about three percent.' The future is not bright. However, un...

Introduction. Recent changes to primary care trusts' Procedures of Limited Clinical Value (PLCV) policy mean that otolaryngologists must now follow policy rather than exercising clinical judgment when listing patients for tonsillectomy. Objectives. To gauge perception within the general public of when tonsillectomy is acceptable and to compare this to the current policy. Method. All patients or...

against itself but not against others. Each new tumor induced is therefore expected to have a new antigemc individuality. However, cross-reactivity between independently induced tumors has occasionally been reported (2, 5 , 6, 8—10,12, 13). The notion that antigenic determinants may be repeated in different tumors opens the possibility of antigenic typing. The observations of cross-reactivity...

The most contentious, unresolved issue in biomedicine in the last twenty-five years has been how to best address compensated partnerships between academic researchers and the pharmaceutical industry. Law and policy deliberately promote these partnerships through intellectual property law, research funding programs, and drug and device approval pathways while simultaneously condemning them throu...

In this paper, we introduce graph theory, and discuss the Four Color Theorem. Then we prove several theorems, including Euler’s formula and the Five Color Theorem.

AIMS This study was conducted to analyse flow velocity parameters and predictors of a suboptimal coronary flow reserve (<2.5) following balloon angioplasty. METHODS Two hundred and twenty-five patients underwent sequential intracoronary Doppler as part of the DEBATE I study. Of these, 183, with complete angiography and Doppler at the 6-month follow-up, were included. Univariate and multivaria...

The Australia Telescope National Facility Mopra millimetre telescope has been used to search for 95.1-GHz class I methanol masers towards sixty-two 6.6-GHz class II methanol masers. A total of twenty-six 95.1-GHz masers were detected, eighteen of these being new discoveries. Combining the results of this search with observations reported in the literature, a near complete sample of sixty-six 6....

I shall try to approach the subject of the treatment of syphilis with penicillin not so much from a statistical point of view, but rather from the point of view of some fundamental questions of the biology of syphilitic infection and its treatment. I propose to give a brief account of the American experience with penicillin. Treatment has been conducted on an organized co-operative basis, first...
