Samples of white and red wines produced in two different wine-growing regions, coastal (Dalmatia) and continental (Hrvatsko zagorje) of Croatia, were analysed for biogenic amines content. Biogenic amines content was determined, and its concentration levels were associated with the geographical origin of the wine. Due to its high sensitivity, HPLC method with ultraviolet detector was used, including the derivatisation step with dansyl chloride. The method was applied to detect and quantify 11 biogenic amines in 48 red and white wines. It was found that both Dalmatian red and white wines are characterised by tryptamine (0.23–1.22 mg L−1), putrescine (0.41–7.5 mg L−1) and ethanolamine (2.87–24.32 mg L−1). White wines from the Hrvatsko zagorje region are characterised by content of isopentylamine (0.31–1.47 mg L−1), putrescine (0.27–1.49 mg L−1) and ethanolamine (3.80–17.96 mg L−1). In contrast to white wines from the Hrvatsko zagorje region, in the red wines, all biogenic amines except ethylamine, were found and equally presented.

This paper presents the performance analysis of five full-reference objective quality assessment measures on compressed high-resolution video sequences from two publicly available video datasets. Quantitative measures that were accepted by the international research community used in the performance analysis - the correlation coefficient of ranks and the linear correlation coefficient between subjective and objective quality scores. The performance analysis is carried out globally - the level of complete datasets and on subsets of sequences with common characteristics (compression type or source sequence). Three types of compressed video content were analyzed - H.265 and its predecessors H.264 and MPEG-2. The correlation between subjective and objective quality scores is analyzed in different scales (resolutions) of the video signal. From the analysis of the results, very important conclusions on the objective quality assessment of the compressed video signals were derived, as well as the directions for further work.

Article history: Received 3 June 2018 Received in revised form 15 August 2018 Accepted 20 August 2018 The development of ultra-hard cutting tool materials such as cubic boron nitride and ceramics exhibiting excellent wear resistance, chemical stability and hardness at high temperatures have enabled much higher cutting speeds and dry machining. In order to achieve high performance cutting, it is necessary to know the true properties of the cutting tool materials in real operating conditions as well as mechanisms of their failure. The aim of this paper is to determine the properties of certain types of polycrystalline advanced ceramics at a range of loading rates, including dynamics involved in these processes. In order to determine the dynamic fracture toughness of two grades of the material, a crack closure integral method was applied, showing some discrepancy to the static values at high loading rates.

We consider networked control systems (NCSs) composed of a linear plant and a linear controller interconnected by packet-based communication channels with communication constraints. We are interested in the setup where direct-feedthrough terms are present in the plant and/or in the controller, a case that is largely ignored in the literature due to its inherent complexity and counterintuitive results in the analysis despite its relevance for important classes of controllers including Proportional–Integral (PI) regulators. This setup calls for a novel stability analysis, for which we take a renewed look at the concept of uniformly globally exponentially stable (UGES) scheduling protocols that turned out to be instrumental in earlier approaches. We provide a generalization of the UGES property, called (DP,DC)-UGES with DP∕DC being the direct-feedthrough matrices of the plant/controller, respectively, and we present generic conditions on these direct-feedthrough terms DP∕DC such that the classical UGES property of scheduling protocols implies (DP,DC)-UGES. This allows us to derive conditions leading to a maximally allowable transmission interval (MATI) such that stability of the overall NCS is guaranteed. In addition, it is shown that it is possible to get more tailored results for the well-known sampled-data (SD), round-robin (RR), and try-once-discard (TOD) protocols leading to less conservative conditions on the direct-feedthrough terms than the generic ones. We also introduce new (DP,DC)-UGES scheduling protocols, designed to handle the direct-feedthrough terms in a more effective way than existing protocols. Our results are illustrated using the example of a batch reactor.

The book OCT Angiography is a handwriting which presents a good example of establishing a correlation with world literature in the field of new, sophisticated ophthalmology diagnostics. It represents a concise and sufficiently detailed monography on the new OCTA diagnostic method in ophthalmology. It is very important to note that the author of the book used their own material with her own descriptions and comments on every single image included, which gives the material a great value and worthiness. The book has 24 chapters: 1) Optical Coherence Tomography Angiography; 2) Choroidal Neovascularization; 3) Dry Age-related Macular Degeneration; 4) Neovascular/Exudative/Wet Age-related Macular Degeneration; 5) Central Serous Retinography; 6) Polipoidal Choroidal Vassculopathy, Idiopathic Polipoidal Choreidal Vasculopathy; 7) Diabetic Retinopathy; 8) Degenerative Myopia) 9) Retinal Artery Occlusion; 10) Retinal Vein Oclussion; 11) Sybvnchysis Scientillans; 12) Posterior Vitreous Detachment; 13) Epiretinal Membrane, Cellophane Maculopathy and Macular Pucker; 14) Vitreomacular Traction Syndrome; 15) Macular Pseudohole; 16) Lamellar Macular Hole; 18) Full Thickness Macular Hole, Stage 4; 19) Toxoplasmic Chorioretinitis; 20) Albinism; 21) X-linked Juvenile Retinoschisis; 22) Radiation Retinopathy; 23) Glaucoma; 24) Optic Neuritis and Papilledema.

Authors are physicians and teachers from universities in Sarajevo and Tuzla (Bosnia and Herzegovina) and Nis (Serbia). Some of pathological cases are presented with ten to fifteen individual images and figures, aiming to help the reader properly read and analyse the patient from beginning to the end. Also, images are organized so the reader can easily compare and understand correlation between them. Documented findings give the physician a possibility of careful comparison with earlier findings of the classic OCT. The author of this work has very skillfully introduced a reader into anatomy, physiology and pathology of the most common diseases of the posterior ocular segment. The book gives also a very good overview of optic nerve pathology and OCTA findings.

Writing of scientific articles requires high competence and scientific awareness, and the respect of scientific patterns of behavior. Every article should essentially be followed by the IMRAD structure, which is generally represented, with minor modifications, in the entire modern scientific publishing. Writing articles must follow the thread, have a meaningful beginning and end, and from each and every part of the context. Also, it is indicate the benefits of the paper, to its defect, defining ambiguous points that would have the process for further analysis in some subsequent studies by the same or another group of authors. It means, the chapter - Discussion represents the heart of every scientific article. The writing of the discussion itself must point to the specificity of the results of the work itself. Author wants to point out the importance of quality description of chapter Discussion, when scientists prepare their articles with presenting own results comparing it with results of other authors with similar topic.
