an r-module m is called epi-retractable if every submodule of mr is a homomorphic image of m. it is shown that if r is a right perfect ring, then every projective slightly compressible module mr is epi-retractable. if r is a noetherian ring, then every epi-retractable right r-module has direct sum of uniform submodules. if endomorphism ring of a module mr is von-neumann regular, then m is semi-...

orthogonal zero interpolants (ozi) are polynomials which interpolate the “zero-function” at a finite number of pre-assigned nodes and satisfy orthogonality condition. ozi’s can be constructed by the 3-term recurrence relation. these interpolants are found useful in the solution of constrained approximation problems and in the structure of gauss-type quadrature rules. we present some theoretical...

BACKGROUND Smart devices and mobile applications are now an integral part of all aspects of everyday life. They are particularly numerous in the field of health, contributing to the movement called ehealth. What is the potential role of these devices as prevention supports? The purpose of this article is to provide an exploratory analysis of the use, efficacy and contribution to conventional pr...

Increasingly, firms source more complex and strategic as well as harder to codify information technology projects to lowcost offshore locations. Completing such projects successfully requires close collaboration among all participants. Yet, achieving such collaboration is extremely difficult because of the complexity of the context: multiple and overThis paper was recommended for acceptance by ...

With the development of information and communications technology, user-generated content and crowdsourced data are playing a large role in studies of transport and public health. Recently, Strava, a popular website and mobile app dedicated to tracking athletic activity (cycling and running), began offering a data service called Strava Metro, designed to help transportation researchers and urba...

Materials and methods: Pigs raised under antibiotic-free (ABF) conditions (n = 3424) were vaccinated first with combined Mycoflex and Circoflex (Boehringer Ingelheim Vetmedica Inc, St Joseph, Missouri) and second with ER Bac Plus (Pfizer Inc, Pfizer Animal Health, New York, New York), each via either conventional syringe and needle (Needle) or NFID. The first vaccination was given on the right ...

BACKGROUND The best manner to prevent suicide is to recognize suicidal signs and signals, and know how to respond to them. OBJECTIVE We aim to study the existing mobile apps for suicide prevention in the literature and the most commonly used virtual stores. METHODS Two reviews were carried out. The first was done by searching the most commonly used commercial app stores, which are iTunes an...

The concept of Personal Learning Environments (PLEs) is increasingly gaining importance in academic teaching, private life and occupational settings. The learner is put into focus and offered general conditions for self-organized learning. At the same time mobile technology is becoming omnipresent and an essential part of today’s learning. Although many (web) frameworks have been developed allo...
