Class field theory furnishes an intrinsic description of the abelian extensions of a number field that is in many cases not of an immediate algorithmic nature. We outline the algorithms available for the explicit computation of such extensions.

during a survey on the identification of plant-parasitic nematodes associated with walnut in sanandej region (kurdistan province, western iran), a population of paratylenchus labiosus was collected and identified morphologically. description, illustrations and morphometrics of the species are given and comparisons are made between it and some related species. paratylenchus labiosus comes more c...

The déjà vu experience has piqued the interest of philosophers and physicians for over 150 years, and has recently begun to connect to research on fundamental cognitive mechanisms. Following a brief description of the nature of this

The complex ongoing process of species development is highlighted by the description of a new felid species, Leopardus guttulus, from Brazil. Broad molecular genetic assessments affirm reproductive isolation and separation in nature, the hallmark of species recognition.

what to look for in abbas abad pool? a lake in middle of the forest on the mountain heights with an encircled building with waters and a garden ashore? why are the trees cut and used to build a garden? and what is the purpose of placing a lake on a dominant and deep valley over the khazar sea. today, green trees are grown in abbas abad garden and no sign of landscaping or water features can be ...

this article provides an overview of natural phonological processes in the dialect of sistani persian spoken in iranian sistan, and reviews theoretical implications of these processes. a representative selection of processes in the language is examined in reference to conditioning by surrounding segments and conditioning in reference to syllable structure. while assimilation and dissimilation a...
