interrupting the processes which control ecosystem resources has dramatic impacts on the rangeland conditions. to protect ecosystems and landscape, it needs to understand the ecosystem processes which regulate the ecosystem resources. as main components of ecosystems, patches and inter-patches play important roles in energy and materials cascade. ecologically, functional parameters such as stab...

LEOPARD syndrome is an autosomal dominant hereditary disease, which is characterized with cutaneous pigmented patches, electrocardiographic changes, ocular hypertelorism, retarded growth, pulmonic stenosis, genital abnormalities and congenital deafness. The gene of this disease have high penetrance but expression is varied and incomplete forms may be seen. We report a 23 year-old woman wi...

Background: Different modalities have been tried in order totreat stable vitiligo. Culturing melanocytes is time consumingand expensive. Therefore, new methods using autologousmelanocytes are sought. We aimed to compare the mixed nonculturedautologous melanocytes of the outer root sheath andthe bulge area of hair follicle transplantation plus dermabrasionwith dermabrasion alone in stable genera...

CAD systems are usually based on a tensor product representation of free form surfaces. In this case, trimmed patches are used for modeling non rectangular zones. Trimmed patches provide a reasonable solution for the representation of general topologies, provided that the gap between equivalent trimming curves in the euclidean space is small enough. Several commercial CAD systems, however, repr...

A hexagonal patch is a plane graph in which inner faces have length 6, inner vertices have degree 3, and boundary vertices have degree 2 or 3. We consider the following counting problem: given a sequence of twos and threes, how many hexagonal patches exist with this degree sequence along the outer face? This problem is motivated by the study of benzenoid hydrocarbons and fullerenes in computati...
