In the present work, by using a paralelepipedic thermogravitational microcolumn, the temperature gradient influence on the stability of the flow was or has been examined, emphasizing mixtures with negative Soret coefficients. Experiments and numerical analysis were conducted for DCMIX2 Toulene-Methanol binary subsystem. This binary subsystem has a broad range of negative Soret values for low concentrations of Methanol which was analysed. Two different concentrations have been studied in order to confirm existence of temporal stability windows of those mixtures. Experiments were compared with numerical simulations conducted in open source software OpenFOAM, for both cases.

This article presents an improved equity momentum measure for corporate bonds, using the euro-denominated global investment-grade corporate bond market from 2000 to 2016. The author documents economically meaningful and statistically significant corporate bond return predictability. In contrast to the widely used total equity return, momentum as measured by the residual (idiosyncratic) equity return appears to further enhance risk-adjusted performance of corporate bond investors. Additional support for this conjecture is obtained from tests for various asset pricing factors and transaction costs, as exposure to these risk factors cannot explain this abnormal pattern in returns.

<p style="text-align: justify;">3D printing is a technology that is increasingly used in many engineering fields and education. This technology is primarily used in rapid prototyping and rapid tooling. In this paper the geometrical accuracy of FDM (Fused Deposition Modelling) 3D printing is presented. For the dimensional test process, a 3D model which contains the characteristic geometrical shapes and dimensions that were used as a reference for measuring on the<br />coordinate measurement machine, has been created. The CAD model was created in SolidWorks software, the model was printed on the Ultimaker 2+ 3D printer and the measurement has been proceeded on the Zeiss Contura G2 coordinate measuring machine.</p>

An example of a pressure sensor on a 4-axis device for measuring the geometry of furniture, a detailed analysis of the recalibration interval was performed, which had to be shortened from 5 to 3 years.</p>

<p style="text-align: justify;">Contraction is a part of a wind tunnel that has the greatest impact on the air flow quality in the test section. The constriction ratio, the cross section shape, the length and wall shape are constructive parameters that influence the uniformity of the flow, the flow turbulence intensity, the flow rotation angularity, the appearance of the flow separation and the thickness of the fluid flow boundary layer in the test section. For this reason, it is very<br />important to choose the optimal combination of the mentioned contraction design parameters. In this paper, an analysis of five different contours of the contraction wall was performed for the square outlet cross-section Ao=0.64 m2, the constriction ratio CR=4 and the contraction length L=1.88 m. With the computer code of Flow Simulation, 25 numerical simulations were performed and the obtained results were analyzed.</p>

Surveying is an undisputed link in the chain of professions that participate in the realization of projects for the construction of various buildings and structures. Different stages of construction require the engagement of geodesists in a different range. The process of construction of the pillar of the viaduct "Briješće" required the collaboration of a large number of experts of various profiles, among which is a geodetic expert. The paper contains a detailed description of geodetic works in the construction of the viaduct pillar, starting from the establishment of the control network to the final control of the pillar construction.

<p style="text-align: justify;">Cranioplasty is the surgical repair of a bone defect in the skull that is left behind after a severe injury or previous operation. It is usually done to protect underlying brain tissue, reduce local pain and to improve the cranial vault aesthetics. Cranial prostheses can be made from different types of materials: autologous bone, titanium, ceramics and polymers. Their production is costly and often requires complex intraoperative processes which sometimes cause poor aesthetic results in large and complex defects. Using a real case, this paper presents a customised polymethyl methacrylate implant production method which involves three dimensional reconstruction based on CT scans, technology of 3D printing and moldmaking<br />from dental plaster.</p>

Nowadays remote sensing is an indispensable source of information about Earth's surface, primarily satellite-based remote sensing systems. Traditionally, the analysis of data collected from a particular area was based on the analysis of the data of one satellite image. The technological revolution improved spatial, temporal and radiometric resolution of satellite images, which allowed time datasets analysis, combining (integrating) data from various sensors, combining images of different scales and better integration with existing data and models. The integration of data from different sources is becoming an increasingly important factor in numerous aspects of remote sensing, and the results of this technique are used in solving everyday problems.

Tema ovog rada je Ecov roman Otok prethodnoga dana koji u sebi, na vrlo specifičan način, tematizira dvije krize moderne (manirizam i postmodernu). Prva je vidljiva kroz razvoj same fabule romana – radnja je smještena u vrijeme prve velike naučne revolucije, a druga je vidljiva kroz književne postupke koji su rezultat obilježja postmodernog romana. Na taj način, Ecov hibridni roman, putem različitih tehnika i postupaka (autoreferencijalnost, ironija, tekstualne igre, mogući svjetovi) dekonstruira sliku moderne (jedinstveno shvaćanje historije, cjelovitosti svijeta, subjekta usredsređenog u sebe) na dva nivoa – sadržajnom (17. stoljeće) i formalnom (20. stoljeće).

Post-traumatic osteomyelitis (OM) is an uncommon event in cats, usually affecting distal phalanges of extremities. Tail injuries seldom cause bone infection, but often result in neural damage with subsequent tail paralysis, and occasionally in urinary/fecal incontinence. We present a case of old stray cat which developed post-traumatic tail OM, and endured it for years. It was an immuno-compromised, neglected, animal strongly infested with larvae of Aelurostrongylus abs trusus and oocistae of Isospora felis. Ultimately, it was treated by tail amputation, with without any health consequences.  Relevance and novel information: This report describes the management and outcome of a rare and a life-threatening case of feline post-traumatic  tail OM which was previously not reported in literature.

Konec 20. in začetek 21. stoletja na območju Tuzlanskega kantona zaznamujejo negativni demografski trendi, kot so upadanje rodnosti, naraščanje smrtnosti, zmanjševanje naravnega prirastka, staranje prebivalstva, zmanjševanje skupnega števila prebivalstva, medtem ko so po letu 1995 neugodne ekonomske, socialne, politične in druge razmere povečale ekonomsko emigracijo, predvsem v populaciji med 20. in 40. letom starosti. Kot rezultat takšnih demografskih trendov se je v povojnem obdobju pospešil proces staranja prebivalstva, kar obrne trend upadanja potencialne biodinamike in vitalnosti prebivalstva. Zaradi negativnih demografskih trendov na tem območju je prišlo do zmanjšanja populacije osnovnošolske starosti. Cilj tega prispevka je identificirati glavne dejavnike, ki vplivajo na to zmanjšanje, kot tudi stopnjo njihovega vpliva na ta proces, s posebnim poudarkom na naravni dinamiki prebivalstva in intenzivni emigraciji prebivalstva. Če v prihodnosti ne bodo sprejeti ustrezni ukrepi populacijske politike, se lahko negativni demografski trendi še bolj izrazijo, kar bi lahko negativno vplivalo na osnovnošolsko izobraževanje v občinah Tuzlanskega kantona.
