Among the most studied graph labelings we have the varieties called alpha and edge-magic. Even when their definitions seem completely different, these labelings are related. A graceful labeling of a bipartite graph is called an a-labeling if the smaller l... see more

Let G = (V, E) be a finite (non-empty), simple, connected and undirected graph, where V and E are the sets of vertices and edges of G. An edge magic total labeling is a bijection a from V ? ... see more

A bipartite graph G with partite sets X and Y is called consecutively super edge-magic if there exists a bijective function f : V(G) ? E(G) ? {1,2,...,|V(G)| + |E(G)|} with the property that f(X) = {1,2,...,|X|}, f(Y) = {|X|+1, |X|+2,...,|V(G)|} and f(u)+... see more

Linear landscape features are used by many species of insectivorous bats as flight routes and foraging zones, as well as for providing protection against environmental factors and predation. However, very little is known about the role that these landscap... see more

In agricultural landscape in northern slope of Mount Slamet, diversity of wild bee species as pollinator depend on forested habitats. This study aimed to assess the effects of distance from the forest edge on the diversity of wild bees on strawberry and t... see more

The sensitivity of intraoperative diagnosis of sentinel lymph node (SLN) metastases in breast cancer is variably low. The purpose of this study was to review the pros and cons of frozen section (FS) and touch preparation (TP) methods, particularly in micr... see more

Trap-nesting bee and wasp inventories are common in Brazil but many phytophysiognomies are still poorly studied. The main objective of this study is to survey trap-nesting bees and wasps in a Semidecidual Seasonal Forest fragment. Also, we test the differ... see more

In this paper we present a technological study of leaf-like arrow points recovered in an open-air site from the 3th millennium B.C., named El Tossal de La Munda (Vistabella del Maestrazgo, Castellón). It is located at the central east of Spain, in the sou... see more
