On Multiple Zagreb Indices of TiO2 Nanotubes
Acta Chimica Slovenica, 2015 The First and Second Zagreb indices were first introduced by I. Gutman and N. Trinajstic in 1972. It is reported that these indices are useful in the study of anti-inflammatory activities of certain chemical instances, and in elsewhere. Recently, the first and second multiple Zagreb indices of a graph were introduced by Ghorbani and Azimi in 2012.

Child &Family Social Work, EarlyView.ABSTRACT Previous studies suggest that emotional parentification contributes to internalised problems in children and adolescents and may be one of the key mechanisms linking adverse family experiences to adolescent internalised problems. Qualitative studies indicate that emotional parentification may emerge as a coping mechanism in response to ...

Computational Analysis of new Degree-based descriptors of oxide networks
Open Chemistry, 2019 Oxide networks have diverse applications in the polymer and pharmaceutical industries. Polynomials and degree-based topological indices have tendencies to correlate properties of molecular graphs.

Conservation Biology, EarlyView.Abstract Knowledge of species distributions is essential for informing policies on nature conservation and restoration. However, updating them on a regular basis and doing so in a harmonized manner at the international level is difficult. The European Bird Census Council integrated national monitoring data covering 5 years to update farmland bird ...

Infrastructure expansion, tourism and electoral outcomes
Economica, EarlyView.Abstract This paper examines the electoral impact of economic growth through increased foreign tourism using data from Croatia. To identify causal effects, the paper applies an instrumental variable strategy, which uses variation in the ruggedness of the local terrain to estimate the network of least‐cost paths.

Kragujevac Journal of MathematicsA tournament is an orientation of a complete simple graph. The score of a vertex in a tournament is the out degree of the vertex. The Zagreb index of a tournament is defined as the sum of the squares of the scores of its vertices. In this paper, we obtain various lower and upper bounds for the Zagreb index of a tournament.

A short note on hyper Zagreb index
Boletim da Sociedade Paranaense de Matemática, 2017 In this paper, we present and analyze the upper and lower bounds on the Hyper Zagreb index $\chi^2(G)$ of graph $G$ in terms of the number of vertices $(n)$, number of edges $(m)$, maximum degree $(\Delta)$, minimum degree $(\delta)$ and the inverse degree $(ID(G))$.

European Journal of Dental Education, EarlyView.ABSTRACT Introduction CAD/CAM (Computer‐Aided Design/Computer‐Aided Manufacturing) technology has become integral to modern dental practice, requiring structured integration into dental education. However, little is known about how well dental students in Croatia understand and engage with these technologies.
