the current study was carried out to investigate the functions of the ritual speech act of ‘ya allah’ (literally meaning ‘o god’) employed by iranians in social interactions. to this end, sixty-two persian native speakers of different age groups, ranging from 35 to 85, of both genders were observed in 250 natural situations such as daily interactions, gatherings, public or private places and lo...

properties of the hybrid of block-pulse functions and lagrange polynomials based on the legendre-gauss-type points are investigated and utilized to define the composite interpolation operator as an extension of the well-known legendre interpolation operator. the uniqueness and interpolating properties are discussed and the corresponding differentiation matrix is also introduced. the applicabili...

A modernized and updated revision of Abramowitz and Stegun, Handbook of Mathematical Functions, first published in 1964 by the National Bureau of Standards, is being planned for publication on the World Wide Web. The authoritative status of the original will be preserved by enlisting the aid of qualified mathematicians and scientists. The practical emphasis on formulas, graphs and numerical eva...

In many languages, the indefinite article emerges from the numeral ONE. In the course of its diachronic development it acquires additional functions such as marking of specificity and genericity. Thus, different functions of indefinite articles can be seen as stages in the process of grammaticalization. This paper examines the use of edin in Bulgarian as a marker of indefiniteness. It shows tha...

in this study the trend of technological change and its nature was studied in production of sugar beet in iran by using dual approach. this approach is useful for estimating the demand structure of the input price change and technology status. after estimating the various forms of flexible functions, by selection of translog cost function with cost share equations system is estimated using seem...

Inland waters are important ecosystems for both their biodiversity and the services they provide to humans. Monitoring components is essential improve knowledge of structure functions these assess health status. [...]

Genetic parameters for stayability to six ages (ST1, . . ., ST6), for five measures of stayability to calving (SC2, . . ., SC6), and for five measures of stayability to weaning (SW2, . . ., SW6), were estimated using records of 2,019 Hereford cows collected from 1964 to 1979 from a selection experiment with a control line and three lines selected for weaning weight, yearling weight, and an inde...

The model of the Big Bang is an integral part of the national curriculum for England. Previous work (e.g. Baxter 1989) has shown that pupils often come into education with many and varied prior misconceptions emanating from both internal and external sources. Whilst virtually all of these misconceptions can be remedied, there will remain (by its very nature) the obstacle of ex-nihilo, as charac...

the acid-base status and arterial blood gas change with temperature variation. to determine the changes in arterial ph and pc02, arterial blood samples of 50 neonates with different clinical conditions were examined at temperatures of 35 to 42°c with an increment of 0.5° c, which resulted in two nonlinear equations with perfect fit on data. the temperature correction factors of these equations,...
