In saying that consonant clusters are broken up, one should not be led to think that this is a description of the phonology of what may be a variety of English (in this case Hong Kong) in terms of deviation from a perceived standard. (See Mohanan 1992 for extensive discussion on the fallacies of such an approach.) Instead, the question should be: When Cantonese speakers hear English words, what...

INTRODUCTION This was a retrospective study conducted to assess the nature, presentation, mode of insertion, diagnosis and management of foreign bodies in the urinary bladder. METHODS Between January 1998 and December 2007, 20 patients with foreign bodies in their urinary bladder were treated at our centre. The records of these patients were reviewed and analysed for their symptoms, mode of i...

When biodiversity is examined in the context of species richness, a consistent feature emerges: Most taxonomic groups are speciespoor, relatively few are species-rich, and the frequency distribution has the shape of a so-called “hollow curve” (1, 2) (Fig. 1A). Attempts to explain hollow-curve distributions often compare real data to hollow curves generated from models (2, 3). These approaches f...

our planet is threatened by nuclear wars, climate change and degradation of biodiversity. the first two dangers are relatively focused on, but biodiversity degradation is not properly considered yet. species diversity is mostly composed of biodiversity and is considered an index of changes in ecosystems. many of researchers think of higher species diversity as an index of bio-system’s stability...

OBJECTIVE To estimate the frequency of needle stick injuries (NSI) among health care workers (nurses, student nurses and paramedical staff) in public hospitals of Karachi. STUDY DESIGN Cross sectional, observational. PLACE AND DURATION OF STUDY This study was conducted in three public tertiary care hospitals of Karachi, from November 2007 to January 2008.

In this work, the chronic toxicity of a mixture of light-stick chemicals and water was tested. The light-stick is used in fishery activities to catch swordfish. The tubes were collected on the beaches of the Costa dos Coqueiros BA, Brazil, in the period from 14th to 31st July 2007. The method used was a short chronic toxicity test where embryos of the sea urchins Echinometra lucunter and Lytech...

Studies on diving behaviour classically divide a dive into three phases: the descent, bottom and ascent phases, with foraging assumed to occur during the bottom phase. The greater complexity of dive revealed through modern, high resolution data highlights the need to re-assess this approach and to consider a larger number of phases within individual dives. Two southern elephant seals (SES) were...
