Mereological relationships--relationships between parts and wholes--are essential for ontological engineering in the anatomical domain. We propose a knowledge engineering approach that emulates mereological reasoning by taxonomic reasoning based on SEP triplets, a special data structure for the encoding of part-whole relations, which is fully embedded in the formal framework of standard descrip...

Web information contain plentiful, significant knowledge which is eager to be explored by users. Effective semantic layered technology not only can provide theoretical support for knowledge discovery in Web resources, but also can improve the searching efficiency of the related information system. This paper builds the multi-layer theory of association semantic based on the power-law distributi...

this epidemiological review was carried out to display the magnitude and the geographic distribution of scorpion envenomation in iran with focus on the southwestern region of iran, particularly. the iranian recognized scorpions belonging to two families, including buthidae and scorpionidae. buthidae family consists of 14 genuses, 26 species, and 18 sub-species, while scorpionidae family has thr...

many health studies were interested to find the association between multiple predictors with a dependent variable. the popular method to analyze these studies was multiple regressions that assumed the predictors were independent. while in practice some predictors may depend on each other and they could not be presented in a regression model simultaneously, as a result the appropriate models suc...

background: national institute of environmental health sciences (niehs) scientists shows that long-term exposure to air pollutants increases the risk of respiratory diseases such as allergies, asthma, chronic obstructive pulmonary disease, and lung cancer. children and the elderly are particularly vulnerable to the health effects of ozone, fine particles, and other airborne toxicants. air pollu...

Two wings may be said to have equivalent pressure distributions if the distribution of M~, the component of surface Mach number normal to the local isobars, is the same in both cases. A simple approximate method is given of calculating Mn from a knowledge of the pressure distribution, and some satisfactory comparisons with a more accurate theory are obtained. It is then possible to define an eq...
