Fungi are organisms that do not have chlorophyll and heterotrophic. can be found everywhere, both in the tropics, subtropics, at North Pole Antarctica. Mushrooms very diverse types. The area of Lombongo Tourism Park, Gorontalo Province has various types mushrooms. Park is an under foot Tilong Kabila mountain Bone Bolango Regency, Province. purpose this study was to identify macroscopic fungi Th...

b a ckground: aquatic insects are the  major groups of arthropods that spend  some parts of their life cycle in the water. these insects play an important role for transmission of some human and animal diseases. there is few information about the aquatic insects fauna of iran. m e t hods: to study the aquatic insects fauna, adult, nymphal and larval collections were carried out from different h...

— We present constructions of codes obtained from maximal orders over number fields. Particular cases include codes from algebraic number fields by Lenstra and Guruswami, codes from units of the ring of integers of number fields, and codes from both additive and multiplicative structures of maximal orders in central simple division algebras. The parameters of interest are the code rate and the ...

This note is devoted to the study of families quaternionic modular forms arising from orders defined by Pizer. In this situation, Hecke eigenspaces are 2-dimensional contrary classical case Eichler orders. The main result a Control Theorem in spirit Hida, interpolating these eigenspaces. We restrict our attention definite rational quaternion algebra ramified at single odd prime [Formula: see te...

In 1978, Dhar suggested a model of a lattice gas whose states are partial orders. In this context he raised the question of determining the number of partial orders with a xed number of comparable pairs. Dhar conjectured that in order to nd a good approximation to this number, it should suuce to enumerate families of layer posets. In this paper we prove this conjecture and thereby prepare the g...
