Some Characterizations of Specially Multiplicative Functions
A multiplicative function f is said to be specially multiplicative if there is a completelymultiplicative function fA such that f(m)f(n)= ∑ d|(m,n) f (mn/d)fA(d) for allm andn. For example, the divisor functions and Ramanujan’s τ-function are specially multiplicative functions. Some characterizations of specially multiplicative functions are given in the literature. In this paper, we provide so...

Our cross-sectional data on market shares consists of 1,171 brands in 91 product categories of foods and sporting goods sold in the United States. One of our results is that the pattern of market shares for each of the categories (many of which are fundamentally dissimilar, such as breakfast cereals and rifles) is represented...
متن کاملSoil trampling in an Antarctic Specially Protected Area : tools to assess levels of human impact
Research in extremely delicate environments must be sensitive to the need to minimize impacts caused simply through the presence of research personnel. This study investigates the effectiveness of current advice relating to travel on foot over Antarctic vegetation-free soils. These are based on the concentration of impacts through the creation of properly signed and identified paths. In order t...

متن کاملSome physiopathologic regularities in the process of dying and resuscitation.
COMPLETE STUDY of the mechanisms of death and resuscitation represents one of the typical trends in the development of modern biology. Investigators were faced with a new class of biological phenomena when the accepted laws and regularities often contradicted the usual concepts of the functions of the living body. A new branch of medical science has come into being, devoted to the physiopatholo...
