Beach seines are widely used to estimate the density and species richness of fishes in estuaries. We evaluated the causes and extent of bias in estimates from seines using a series of field experiments in small estuaries in southern California, USA. Seining in spatially paired areas that were either enclosed by block nets or not, revealed that seines used without block nets underestimated densi...

Abstract This study uses acoustic energy measures for /b, d, g/ after /f, s, ∫, l, r/ in Catalan in order to test whether postconsonantal voiced stop lenition is ruled by minimization of articulatory effort, acoustico-perceptual continuity of an ongoing prosodic constituent or some other principle of articulatory organization. Data for eight speakers reveal that lenition is more prone to operat...

We are analyzing storage structures for two and three dimensional raster type data which are used for feature retrieval The features are one two or three dimensional objects with regular outlines like a rectangle or a prism The features could be parts of a map or image an area of special interest for searching after oil a sequence of ultra sound images and so on The storage medium is magnetic d...

Ultrasound is one of the most widely used multipurpose imaging modalities that is ideal for monitoring and diagnosing early pregnancy events. The first sign and measurable element of an early pregnancy is the Gestational Sac (GS). Currently, the size of GS is manually measured from an ultrasound image of the GS. This paper argues that the Mean Sac Diameter (MSD) derived from the manual measurem...

The prevalence of fluorosis is mainly due to the consumption of more fluoride through drinking water. It is necessary to find out the fluoride endemic areas to adopt remedial measures to the people on the risk of fluorosis. The objectives of this study are to estimate the fluoride exposure through drinking water from people of different age group and to elucidate the fluoride endemic areas thro...

A 29-year-old female with Uhl's anomaly developed complete atrioventricular (A-V) block. His bundle studies revealed block distal to the His bundle recording site with narrow QRS complexes. Right ventricular capture could not be obtained and despite successful left ventricular epicardial pacing, the patient died. Autopsy revealed absence of myocardium in most areas of the right ventricle and th...

This paper describes a binary image representation scheme, which is called Image Block Representation and presents a new skeletonization algorithm, which is fast implemented on block represented binary images. The main purpose of the Image Block Representation is to provide an efficient binary image representation that permits the execution of operations on image areas instead of image points. ...
