Mechanical stimulation of plants can be caused by various abiotic and biotic environmental factors. Apart from the negative consequences, it can also cause positive changes, such as acclimatization of plants to stress conditions. Therefore, it is necessary to study the physiological and biochemical mechanisms underlying the response of plants to mechanical stimulation. Our aim was to evaluate the response of model plant Arabidopsis thaliana to a moderate force of 5 N (newton) for 20 s, which could be compared with the pressure caused by animal movement and weather conditions such as heavy rain. Mechanically stimulated leaves were sampled 1 h after exposure and after a recovery period of 20 h. To study a possible systemic response, unstimulated leaves of treated plants were collected 20 h after exposure alongside the stimulated leaves from the same plants. The effect of stimulation was assessed by measuring oxidative stress parameters, antioxidant enzymes activity, total phenolics, and photosynthetic performance. Stimulated leaves showed increased lipid peroxidation 1 h after treatment and increased superoxide dismutase activity and phenolic oxidation rate after a 20-h recovery period. Considering photosynthetic performance after the 20-h recovery period, the effective quantum yield of the photosystem II was lower in the stimulated leaves, whereas photochemical quenching was lower in the unstimulated leaves of the treated plants. Nonphotochemical quenching was lower in the stimulated leaves 1 h after treatment. Our study suggested that plants sensed moderate force, but it did not induce pronounced change in metabolism or photosynthetic performance. Principal component analysis distinguished three groups–leaves of untreated plants, leaves analysed 1 h after stimulation, while stimulated and unstimulated leaves of treated plants analysed 20 h after treatment formed together the third group. Observed grouping of stimulated and unstimulated leaves of treated plants could indicate signal transduction from the stimulated to distant leaves, that is, a systemic response to a local application of mechanical stimuli.

Glass fragments found in crime scenes may constitute important forensic evidence when properly analyzed, for example, to determine their origin. This analysis could be greatly helped by having a large and diverse database of glass fragments and by using it for constructing reliable machine learning (ML)-based glass classification models. Ideally, the samples that make up this database should be analyzed by a single accurate and standardized analytical technique. However, due to differences in equipment across laboratories, this is not feasible. With this in mind, in this work, we investigated if and how measurement performed at different laboratories on the same set of glass fragments could be combined in the context of ML. First, we demonstrated that elemental analysis methods such as particle-induced X-ray emission (PIXE), laser ablation induct i v e l y coupled plasma mass spectrometry (LA-ICP-MS), scanning electron microscopy with energy-dispersive X-ray spectrometry (SEM-EDS), particle-induced Gamma-ray emission (PIGE), instrumental neutron activation analysis (INAA), and prompt Gamma-ray neutron activation analysis (PGAA) could each produce lab-specific ML-based classification models. Next, we determined rules for the successf u l combinations of data from different laboratories and techniques and demonstrated that when followed, they give rise to improved models, and conversely, poor combinations wi l l lead to poor-performing models. Thus, the combination of PIXE and LA-ICP-MS improves the performances by similar to 10-15%, while combining PGAA with other techniques provides poorer performances in comparison with the lab-specific models. Finally, we demonstrated that the poor performances of the SEM-EDS technique, sti l l in use by law enforcement agencies, could be greatly improved by replacing SEM-EDS measurements for Fe and Ca by PIX E measurements for these elements. These findings suggest a process whereby forensic laboratories using different elemental analysis techniques could upload their data into a unified database and get reliable classification based on lab-agnostic models. This in tur n brings us closer to a more exhaustive extraction of information from glass fragment evidence and furthermore may form the basis for international-wide collaboration between law enforcement agencies.

Erektilna disfunkcija je trajna nemogućnost postizanja i održavanja erekcije dostatne za zadovoljavajuću spolnu aktivnost. Istraživanja pokazuju da preko 50% muškaraca u dobi od 40 do 70 godina pati od ED-a, no točan broj teško je procijeniti s obzirom da se mnogi muškarci rijetko javljaju liječniku radi navedenog problema. ED se etiološki može klasificirati na psihogenu, organsku, i mješovitu. Organska ED uključuje vaskulogenu, neurogenu, endokrinološku i medikamentoznu etiologiju. ED uzrokuje pad kvalitete života pacijenta i njegovog partnera. Stres i depresija često prate bolest pa s vremenom skoro sve organske disfunkcije najčešće postaju miješane. Najčešći čimbenici rizika za ED su hipertenzija, dijabetes melitus, pušenje, dislipidemije, pretilost, fizička neaktivnost i stres. Osnovni postupci pri dijagnosticiranju ED-a obuhvaćaju temeljitu anamnezu, fizikalni pregled, hormonske i biokemijske analize te procjenu psihološkog profila pacijenta. Kod nekih pacijenata bit će potrebne daljnje pretrage. Prva linija terapije ED-a obuhvaća promjenu životnih navika, farmakoterapiju oralnim inhibitorima PDE5 te korištenje vakuumskih uređaja za erekciju. U slučaju nedjelotvornosti prve linije terapije, kao sekundarna linija koriste se intrakavernozne injekcije ili intrauretralni supozitoriji alprostadila. U tercijarnu liniju terapije spadaju kirurške metode., Erectile dysfunction is defined as the inability to achieve and maintain an erection sufficient for satisfactory sexual activity. Research shows that over 50% of men between the ages of 40 and 70 suffer from ED, but the exact number is difficult to estimate, given that many men rarely seek medical help about the problem. ED can be etiologically classified into psychogenic, organic, and mixed ED. Organic ED includes vasculogenic, neurogenic, endocrinological and medicamentous etiologies. ED causes a decline in the quality of life of the patient and his partner. Stress and depression often accompany ED, so over time almost all organic dysfunctions usually become mixed. The most common risk factors for ED are hypertension, diabetes mellitus, smoking, dyslipidemia, obesity, physical inactivity and stress. Basic procedures for diagnosing ED include a thorough medical history, physical examination, hormonal and biochemical analyses, and assessment of the patient's psychological profile. Some patients will require further testing. The first-line therapy for ED includes lifestyle changes, pharmacotherapy with oral PDE5 inhibitors and the use of vacuum-assisted erection devices. In case that the first-line therapy isn't effective, intracavernous injections of alprostadil or intraurethral alprostadil suppositories are used as second-line therapy. The third-line therapy includes surgical methods.

U radu se donose rezultati istraživanja povijesne tvorbe prezentske glagolske osnove u praslavenskome jeziku. Rad se zasniva na suvremenoj indoeuropeističkoj i slavističkoj literaturi te na vlastitoj interpretaciji pojedinih primjera prezentskih osnova ekscerpiranih iz prikupljene građe. Za svaki primjer praslavenske prezentske osnove navode se najvažniji podatci: etimologija, akcentuacija te potvrde iz slavenskih jezika s posebnim naglaskom na građu iz hrvatskih dijalekata. Na istraživačka pitanja postavljena u uvodnome dijelu rada pokušava se odgovoriti u zaključku nakon što smo u središnjem dijelu rada analizirali tvorbu pojedinačnih praslavenskih prezentskih osnova. Istraživačka pitanja vezana su uz baltoslavensko nasljeđe praslavenskih prezentskih osnova i posebnosti u razvoju hrvatskih dijalekata., The aim of this work is to present our research in diachronic derivation of the Proto-Slavic present stem. The work is based on relevant linguistic bibliography and primary sources of the Slavic dialects. The first part of the dissertation presents a theoretical and methodological overview of the verbal morphology in the Indo-European and Balto-Slavic proto-language. We tried to formulate the three major problems regarding the Balto-Slavic verbal derivation, the ProtoSlavic development and attestations of the Proto-Slavic present stems in the contemporary Croatian dialects. A major part of the work is dedicated to the analysis of the Proto-Slavic present stems. Every single Proto-Slavic present stem is described regarding it's etymology, attestation, accentuation and historical derivation.

Beton je materijal čija je primjena vrlo široka što ga čini jednim od vodećih i najrasprostranjenijih materijala današnjice. Koristi se u zgradarstvu, u izgradnji mostova, kanala, brana, tunela i slično.

Humanitarian demining is an indispensable part of any post-conflict reconstruction and rehabilitation efforts, as landmines and other unexploded ordnance (UXO) continue to pose a significant threat to civilians and infrastructure. Traditional non- technical survey demining methods are typically time-consuming, labor-intensive, and require professional familiarity with a number of different complex tools and involved procedures. The emergence of the latest artificial intelligence (AI) technologies for deep learning (DL) and data analysis techniques presents an opportunity to transform humanitarian demining by significantly improving its efficiency, speed, accuracy, and safety. One such approach is the development of a data observatory that implements data ingestion pipelines into a data lake using data transformation to improve the usability of unstructured data about a mine scene. This paper addresses the key characteristics and benefits of such a system and its potential to improve humanitarian demining.
