helicobacter pylorus (hp) is a common infection in iran. inappropriate laboratory tests for its diagnosis such as serology and irrational drug prescription for hp treatment in patients with non-ulcer dyspepsia is a drastic obstacle in our country. treating every patient with dyspepsia without peptic ulcer or precancerous lesions, not only results in high economic burden on health system, but al...

Given a function f : I → J and a pair of means M and N, on the intervals I and J respectively, we say that f is MN -convex provided that f (M(x, y)) N(f (x), f (y)) for every x , y ∈ I . In this context, we prove the validity of all basic inequalities in Convex Function Theory, such as Jensen’s Inequality and the Hermite-Hadamard Inequality. Mathematics subject classification (2000): 26A51, 26D...

This paper discusses site selection process for biological soil conservation planning. It was supported by a valuefocused approach and spatial multi-criteria evaluation techniques. A first set of spatial criteria was used to design a number of potential sites. Next, a new set of spatial and non-spatial criteria was employed, including the natural factors and the financial costs, together with t...

it is well-known that “casual conditional” in islamic logics has been used with two meanings: “specific conditional” and “general conditional”. however, viewing the works of the muslim logicians, we find out that these two meanings of “casual conditional” have been interpreted in two various ways: each of the general and specific conditionals is sometimes interpreted as the condition of “non-ne...

Gabapentin is an anticonvulsant widely used in the treatment of epilepsy.An accurate and validated spectrophotometric method was developed as an alternative method to determine gabapentin in pharmaceutical products. This is a simple, accurate, precise, selective and visible spectrophotometric method. The method is based on the measurement of drug absorbance as a result of yellow solution format...
