Born in Rijeka and studied medicine in Vienna, Paris and Prague. He started his medical career in Belgrade State Hospital in 1920 but since 1922 he worked as an assistent at the State Institute of Epidemiology in Zagreb. In 1924 he was sent to USA to specialize in bacteriology, serology and immunology. Back in Zagreb he was engaged in antidiphtheric serum production. Later he became more intere...

Recently two new degree concepts have been defined in graph theory: ev-degree and ve-degree. Also the evdegree and ve-degree Zagreb and Randić indices have been defined very recently as parallel of the classical definitions of Zagreb and Randić indices. It was shown that ev-degree and ve-degree topological indices can be used as possible tools in QSPR researches . In this paper we d...

The reformulated Zagreb indices of a graph is obtained from the classical Zagreb by replacing vertex degree by edge degree and are defined as sum of squares of the degree of the edges and sum of product of the degrees of the adjacent edges. In this paper we give some explicit results for calculating the first and second reformulated Zagreb indices of dendrimers. Mathematics Subject Classificati...

The relationship between the bone mineral density (BMD) in Croatian female adults and the average incoming solar radiation at the ground was investigated. The study included 387 volunteers of average age of 60 years from three different towns: Pula (n = 128, age from 35 to 76), Krapina (n = 141, age from 43 to 77), and Zagreb (n = 118, age from 32 to 79). Apart from the different lifestyle, eac...

for a graph $g$ with edge set $e(g)$, the multiplicative sum zagreb index of $g$ is defined as$pi^*(g)=pi_{uvin e(g)}[d_g(u)+d_g(v)]$, where $d_g(v)$ is the degree of vertex $v$ in $g$.in this paper, we first introduce some graph transformations that decreasethis index. in application, we identify the fourteen class of trees, with the first through fourteenth smallest multiplicative sum zagreb ...

‎for a graph $g$ with edge set $e(g)$‎, ‎the multiplicative second zagreb index of $g$ is defined as‎ ‎$pi_2(g)=pi_{uvin e(g)}[d_g(u)d_g(v)]$‎, ‎where $d_g(v)$ is the degree of vertex $v$ in $g$‎. ‎in this paper‎, ‎we identify the eighth class of trees‎, ‎with the first through eighth smallest multiplicative second zagreb indeces among all trees of order $ngeq 14$‎.

AIM To identify factors contributing to significant differences between two university hospital departments of ophthalmology, one in Paris, France, and the other in Zagreb, Croatia, in their clinical effectiveness and cost-efficiency. METHOD Structural, clinical, and financial characteristics of a Croatian and French ophthalmology department were compared for the 1996-2000 period. We used Par...
