This paper presents data on the diversity and distribution of Balkan endemic vascular plants on the Konjuh Mountain in northeastern Bosnia and Herzegovina. Konjuh is characterized by geological heterogeneity and a significant proportion of ophiolitic substrate, which supports the development of endemic-relict serpentinophytes. A total of 31 endemic and four subendemic taxa were recorded in the surveyed area. Among these, Caryophyllaceae, with five recorded endemic taxa, is the most abundant family. The analysis of life forms and chorological spectra showed a dominance of hemicryptophytes and taxa from the South European and Mediterranean-Sub-Mediterranean chorological groups. The majority of endemic and relict taxa in the surveyed area are serpentinophytes. A total of 18 recorded taxa are listed as threatened according to the Red List of Flora of the Federation of Bosnia and Herzegovina. The species findings are presented with a distribution map. The distribution range of endemic and endangered taxa in Konjuh extends beyond the protected area. The results provide a list of locations of particular interest for further research and potential protection due to the diversity of endemic taxa.

Modern business systems have the expectations and requirements of users and stakeholders for safer and better services that are constantly growing. The increasing use of information technology in business increases the threats and vulnerabilities to which information resources are exposed, which causes an increase in information risks. Many business institutions must constantly monitor their activities to establish an organized and sustainable information security management system and services. The requirements of the international standard ISO/IEC 27001 and the generally accepted COBIT management framework are important for the application of such a system. The paper presents a model of a sustainable information security management system (ISMS) at universities.

The chemical industry is the leading sector in the EU in terms of added value. However, contaminants pose a major threat and significant costs to the environment and human health. While EU legislation and international conventions aim to reduce this threat, regulators struggle to assess and manage chemical risks, given the vast number of substances involved and the lack of data on exposure and hazards. The European Green Deal sets a ‘ zero pollution ambition for a toxic free environment ’ by 2050 and the EU Chemicals Strategy calls for increased monitoring of chemicals in the environment. Monitoring of contaminants in biota can, inter alia: provide regulators with early warning of bioaccumulation problems with chemicals of emerging concern; trigger risk assessment of persistent, bioaccumulative and toxic substances; enable risk assessment of chemical mixtures in biota; enable risk assessment of mixtures; and enable assessment of the effectiveness of risk management measures and of chemicals regulations overall. A number of these purposes are to be addressed under the recently launched European Partnership for Risk Assessment of Chemicals (PARC). Apex predators are of particular value to biomonitoring. Securing sufficient data at European scale implies large-scale, long-term monitoring and a steady supply of large numbers of fresh apex predator tissue samples from across Europe. Natural science collections are very well-placed to supply these. Pan-European monitoring requires effective coordination among field organisations, collections and analytical laboratories for the flow of required specimens, processing and storage of specimens and tissue samples, contaminant analyses delivering pan-European data sets, and provision of specimen and population contextual data. Collections are well-placed to coordinate this. The COST Action European Raptor Biomonitoring Facility provides a well-developed model showing how this can work, integrating a European Raptor Biomonitoring Scheme, Specimen Bank and Sampling Programme. Simultaneously, the EU-funded LIFE APEX has demonstrated a range of regulatory applications using cutting-edge analytical techniques. PARC plans to make best use of such sampling and biomonitoring programmes. Collections are poised to play a critical role in supporting PARC objectives and thereby contribute to delivery of the EU’s zero-pollution ambition.

Abstract Analysis of representative tools for SQL query processing on Hadoop (SQL-on-Hadoop systems), such as Hive, Impala, Presto, Shark, show that they are not still sufficiently efficient for complex analytical queries and interactive query processing. Existing SQL-on-Hadoop systems have many benefits from the application of modern query processing techniques that have been studied extensively for many years in the database community. It is expected that with the application of advanced techniques, the performance of SQL-on-Hadoop systems can be improved. The main idea of this paper is to give a review of big data concepts and technologies, and summarize big data optimization techniques that can be used for improving performance when processing big data.

Sison amomum L. (Apiaceae) was recorded for the first time in Bosnia and Herzegovina during a fieldwork in the vicinity of the city of Tuzla (northeast Bosnia) in September 2019. This study reports the newly discovered localities and presents a short morphological description of the species.
