The paper deals with inductive, positional and Σ−compositions of terms in order to describe some varieties defined by such compositions. In algebra, equational logic, theoretical computer science, etc. the composition of terms is defined as replacements of some variables by external terms. We consider the positional composition of terms as a tool, which allows us to extend the derivation rules ...

Within and across languages the realization of consonant voicing is highly variable. This study aims to identify, and quantify, the segmental, prosodic and positional factors that have an influence on consonant voicing. A widely used acoustic measure of voicing, viz. voice onset time, is known to have disadvantages both in a cross-linguistic framework, where it fails to provide sufficient Infor...

Algebraic expressions are derived for the open-circuit voltage induced on a toroidal coil with unevenly spaced turns, by a sinusoidal current through its aperture. The derivation requires that the winding layer is thin, the number of turns is large, and the cross-section of the winding is rectangular. These expressions are used to determine the effects of the gap between the ends of the coil an...

Understanding the 'tool kit' that builds the most fundamental aspects of animal complexity requires data from the basal animals. Among the earliest diverging animal phyla are the Cnidaria which are the first in having a defined body plan including an axis, a nervous system and a tissue layer construction. Here I revise our understanding of patterning mechanism in cnidarians with special emphasi...

INTRODUCTION Benign paroxysmal positional vertigo (BPPV) is a clinical syndrome that is proposed to be caused by dislocated utricular debris into semicircular canals. Although the majority of patients are treated by one or two repositioning maneuvers, some of the patients need repeated maneuvers for relief. OBJECTIVE The goal of this study was to investigate the factors associated with patien...

UNLABELLED Benign Paroxysmal Positional Vertigo is one of the most common causes of dizziness. Its characteristic clinical profile is dizziness at head movements. The main diagnostic maneuver of posterior canal Benign Paroxysmal Positional Vertigo is the Dix-Hallpike test. If the maneuver is positive (vertigo and/or nystagmus), the physician can perform the Epley maneuver on the injured side. ...

Ink-jet printing is a method for directly patterning and fabricating patterns without the need for masks. To achieve this, the fluids used as inks must have the capability of being stably and accurately printed by ink-jetting. We have investigated the inter-relationship between ink-jet printability and physical fluid properties by monitoring droplet formation dynamics. The printability of the f...

The recent identification of molecularly defined human tumor antigens recognized by autologous CTLs has opened new opportunities for the development of antigen-specific cancer vaccines. Despite extensive work, however, the number of CTL-defined tumor antigens that are suitable targets for generic vaccination of cancer patients is still limited, mostly because of the painstaking and lengthy natu...
