both in the prenatal and postnatal period2. The syndrome is like a big puzzle whose parts need to be carefully assembled to get a whole picture.2 Good multidisciplinary approach, proper communication and collaboration with parents and all physician’s involved are required in the diagnostic process. All available resources and tools are needed to increase diagnostic precision in the prenatal diagnosis of fetal syndromes.4

The aqueous extract of the Helichrysum italicum leaves (HI) is tested as a corrosion inhibitor of an iron in a simulated acid rain using potentiodynamic polarisation, cyclic voltammetry and electrochemical impedance spectroscopy. Results of all electrochemical methods indicate an increase of a corrosion inhibition efficiency of the iron with the HI extract concentration. Maximum inhibition efficiency (~ 50 %) is obtained at 2.0 g L–1 HI extract. The inhibitive action is assumed to occur via an adsorption of the HI extract on the iron surface. Results indicate that the adsorption process is spontaneous and follows the Freundlich adsorption isotherm. According to the calculated ΔG value (~ 15 kJ mol–1), the corrosion inhibition of the iron occurs predominantly via a physisorption of the HI extract. The concentration of iron ions released into a solution, measured by atomic absorption spectrometry, is in accordance with the electrochemical results.

A voltage-controlled current amplifier/attenuator in a standard 0.35-<inline-formula> <tex-math notation="LaTeX">${\mu }\text{m}$ </tex-math></inline-formula> CMOS technology is presented. It is based on the resistive mirror method, using non-saturated MOSFETs. An open-loop design with no compensation capacitors provides a high stability and a small occupied chip area of 0.0126 mm². A current gain dynamic range of 513 (54.2 dB), a gain-bandwidth product of 1.78 GHz at the largest current gain of 35.9 dB, and a maximum power consumption of 250 <inline-formula> <tex-math notation="LaTeX">${\mu }\text{W}$ </tex-math></inline-formula> with a single supply voltage of 1.3 V are achieved. In addition, an AC current source has been designed, integrated on the same chip, and used as the input of the proposed voltage-controlled amplifier/attenuator.

We live in a rapidly changing global society, where no one can predict the outcome of the economic, social, and political structures of the world. Changes in science, technology, and economics are particularly noticeable and are closely linked to human life. These changes create new opportunities but also challenges in new areas of everyday activity in order to achieve sustainable development. For countries to compete with each other, they must be creative and innovative in all fields to cope with domestic, national, and global issues. Current economic competitiveness is based on the capabilities of a country and their respective companies to be and stay innovative. This is the main reason why many governments place innovativeness at the center of their growth strategies so that they can foster economic progress and global competitiveness in general. The recognition and need for identification of innovation as a driver of change are evident on a company level as well. This study will use secondary data collected this year from the World Economic Forum to identify critical challenges and opportunities for B&H competitiveness. Also, the results of this research identified enabling environment and markets impact the innovation ecosystem. Practical contribution relates to concrete implications and recommendations that can be used for the improvement of Bosnia and Herzegovina innovativeness.

Existing approaches to business process model-driven synthesis of data models are characterized by a direct synthesis of a target model based on source models represented by concrete notations, where the synthesis is supported by monolithic (semi)automatic transformation programs. This article presents an approach to automated two-phase business process model-driven synthesis of conceptual database models. It is based on the introduction of a domain specific language (DSL) as an intermediate layer between different source notations and the target notation, which splits the synthesis into two phases: (i) automatic extraction of specific concepts from the source model and their DSL-based representation, and (ii) automated generation of the target model based on the DSL-based representation of the extracted concepts. The proposed approach enables development of modular transformation tools for automatic synthesis of the target model based on business process models represented by different concrete notations. In this article we present an online generator, which implements the proposed approach. The generator is implemented as a web-based, service-oriented tool, which enables automatic generation of the initial conceptual database model represented by the UML class diagram, based on business models represented by two concrete notations.
