Canine leishmaniosis (CanL) caused by Leishmania infantum, is a zoonotic vector-borne disease endemic in the Mediterranean region. Here, we report a molecularly confirmed case of fatal CanL caused by L. infantum in the south of Bosnia and Herzegovina where epidemiology data are scarce. A 2.5-year-old, male golden retriever presented with a history of lethargy, prostration, and anorexia. Clinical examination revealed pale mucosae membranes, reduced capillary refill time, anuria, and ulcerated oral mucosae and skin of the legs. Complete blood count discovered severe non-regenerative, normocytic and normochromic anemia. Biochemistry profile showed hyperglycemia, hypoalbuminemia, hypercholesterolemia, increased potassium, and considerably elevated creatinine, urea, and phosphorus. Rapid Leishmania SNAP test was negative, as well as the serum neutralization test for leptospirosis. At necropsy, mildly enlarged and firm yellow to tan kidneys were the most prominent lesions. Macrophages laden with amastigotes in bone marrow, liver, spleen, kidneys, lymph nodes and the skin were seen in histopathology. Molecular testing by PCR and sequencing (cpb gene) confirmed and identified the pathogen as L. infantum. This study highlights the lack of key measures necessary to undertake the proper control of this important zoonosis in the country. Nationwide epidemiologic study on CanL and its vector(s), along with adoption and establishment of proper diagnostic approach with quantitative serologic and molecular methods in place are warranted.

Abstract The effect of Satureja montana L. extract (SM) and phenolic fraction of Satureja montana L. (PF) on the corrosion behaviour of iron in 0.1 mol L-1 sodium chloride solution was studied by electrochemical techniques, UV/Vis spectrophotometry and atomic absorption spectrometry. The results of all techniques showed that SM and PF contributed to iron corrosion inhibition. The calculated inhibition efficiency values were about 45% for SM and 55% for PF. Results indicate that the inhibitive action occurs via a precipitation of the Fe-complex onto the iron surface which resulting in a decrease of the passive current density. The atomic absorption spectrometry (AAS) method was applied to the quantitative determination of iron in solution. The obtained results demonstrated good agreement with results obtained by electrochemical techniques.

Abstract As healthcare turns its focus to preventative community-based interventions, there is increasing interest in using in-home technology to support this goal. This study evaluates the design and use of socially assistive robots (SARs) and sensors as in-home therapeutic support for older adults with depression. The seal-like SAR Paro, along with onboard and wearable sensors, was placed in the homes of 10 older adults diagnosed with clinical depression for one month. Design workshops were conducted before and after the in-home implementation with participating older adults and clinical care staff members. Workshops showed older adults and clinicians sawseveral potential uses for robots and sensors to support in-home depression care. Long-term in-home use of the robot allowed researchers and participants to situate desired robot features in specific practices and experiences of daily life, and some user requests for functionality changed due to extended use. Sensor data showed that participants’ attitudes toward and intention to use the robot were strongly correlated with particular Circadian patterns (afternoon and evening) of robot use. Sensor data also showed that those without pets interacted with Paro significantly more than those with pets, and survey data showed they had more positive attitudes toward the SAR. Companionship, while a desired capability, emerged as insufficient to engage many older adults in long-term use of SARs in their home.

Fruit germplasm plays an important role in the glob a agrobiodiversity and is a source for both a direct use of fruit genetic resou rces as well for fruit breeding programme. The ex-situ field collection is still the main way to successf ully conserve fruit germplasm. Thirty pear accessions fr om Bosnia and Herzegovina were characterized during three years in the ex situ collection maintained by the Institute of Genetic Resources of the University of B anja Luka. The following characteristics were determined: flowering time, harv est maturity time and global tree architecture. The obtained results showed that 53.3% of pear accessions flowered during all three years, 40% of them during two years and 6.7% of them during only one year. The most present tree archite tur form was upright. According to the harvest maturity time, extremely ea rly ccessions were the most represented, than early, medium and very early pear accessions. Conserved pear germplasm in this ex situ collection represents a valuable material for dire ct use and future breeding programmes.

The aim of the present study was to evaluate the effect of one of the most important foliar diseases, powdery mildew, on the leaf physiological traits of Quercus robur L. using chlorophyll a fluorescence parameters in combination with parameters of leaf gas exchange. For this purpose, greenhouse semi-controlled experiment was conducted with 25 one-year-old seedlings kept in optimal conditions, and the same number of seedlings infected with the mentioned pathogen. Measurements were carried out when the coverage of epiphytic micelia visually reached more than 75% of the surface of leaves in the infected seedlings. The results of gas exchange measurement showed that Erysiphe alphitoides (Griffon and Maubl.) U. Braun and S. Takam caused a significant reduction of net photosynthesis (A) and a significant increase in substomatal CO2 concentration (Ci). Furthermore, considering the fast kinetics of chlorophyll a fluorescence, all of the observes parameters were significantly affected by oak powdery mildew. On the other hand, pulse amplitude modulated fluorescence parameters were mildly affected, with only minimal (Fo?) and maximal (Fm?) fluorescence of dark adopted leaves showing significant difference. This study presented the possibility of usage and the effectiveness of chlorophyll a fluorescence parameters in detection the severe stress conditions, on the example of leaves infected with oak powdery mildew over 75%. Some additional studies should be conducted in the future to determine the possibility of usage and the effectiveness of the observed fluorescence parameters of fast kinetics in detection of mild and early stress.

O plakatu kao sredstvu komunikacije Vrijeme u kojem živimo potpuno je usaglaseno sa novim medijima vizuelnih komunikacija u koje se nedvosmisleno ubraja i plakat, sa svojom apsolutno prijemcivom i likovno pretpostavljenom formom, koja prati, osluskuje, provocira, uzbuđuje, obavjestava i uvodi u kompleksan svijet likovnosti i dizajna. Brojni teoreticari, istoricari i umjetnici raznih profila su se bavili njegovom pojavom i analizom, te predlaganjem raznih mogucnosti definisanja samog pojma plakata i plakatske umjetnosti, pa najcesce nailazimo na informacije o plakatu kao umoženoj obavijesti koja se postavlja na javnim mjestima (moguce od rijeci plak -mrljica ili krpica)? U engleskom jeziku se koristi termin poster (prihvaceno i u nasem jeziku kao doslovni prevod), ili posted up (objavljeno, u smislu postavljanja na javno mjesto). U francuskom jeziku se koristi the World Biennial of Student Poster -A Case Study Abstract: The paper World Biennial of Student Poster -A Case Study aims to show the complex structure of the poster as an art form in a historico-analytical and content-wise manner. Viewing the poster in the light of the progressive technological and innovative possibilities of modern information technologies, constantly requires challenging of the scopes and justification of the existence of a "classic" poster. Its role in contemporary society has been analyzed through various forms of manifestation in the spheres of art and modern design. Insufficiently paid attention to the essence of artistic expression through the poster, which has historically been marginalized in relation to classical painting, has positively changed over time, and through the apostrofing of the strength and the range the poster reaches, it has pointed to the significant changes in the society that this type of communication has achieved. In this paper, a prominent event of the Academy of Arts in Novi Sad, the World Biennial of Student Poster, was selected for the case study, and through the analysis of eight exhibitions of the Biennial, its role since 2004 has been evaluated with an obvious improvement in pedagogical and creative work on the poster.

This paper describes the analysis of steel reel shaft as drive shaft in a process of umbilical spooling of wire rope. There is a need to investigate shaft behaviour in the conditions of increasing workload. The aim is to investigate avoiding possible redesign or enabling redesign with minimal costs. Stress analysis has been carried out by using finite element analysis (FEA) and results are compared with the analytically calculated values. Finite element analysis has been carried out using maximum stress criteria and the area of potential failure is found. The main objective of this paper is to find balance in results between "design by rule" and "design by analysis". Design by rule provides rules on how to design a steel reel shaft using analytical equations and other strict rules from design elements. Design by analysis provides rules on using numerical analysis, typically finite element analysis to design a steel reel shaft. The steel reel shaft has been geometrically modelled using SolidWorks. To check all stresses, linear static analysis is done using DSS Simulation and Ansys.

Nanocomposites (HAp/iron oxide), made of hydroxyapatite (HAp) and ferrimagnetic iron oxide, were synthesized by high-energy ball milling a mixture consisting of iron oxide nanoparticles and the starting materials used for the HAp synthesis: calcium hydrogen phosphate anhydrous (CaHPO4), and calcium hydroxide (Ca(OH)2). Two HAp/iron oxide samples with the magnetic phase content of 12 and 30 wt.% were prepared and their microstructure, morphology and magnetic properties were analysed by X-ray diffraction and transmission electron microscopy. Furthermore, the measurement of particle size distribution was performed by laser scattering, and temperature/field dependence on magnetization was determined. X-ray diffraction data confirmed the formation of two-phased samples (HAp and spinel iron oxide) without the presence of any other parasite phase. The shape of particles was nearly spherical in both samples, ranging from only a few to several tens of nanometres in diameter. These particles formed agglomerates with the most common value of the number-based particle size distribution of 380 and 310 nm for the sample with 12 and 30wt.% of iron oxide, respectively. Magnetization data showed that both HAp/iron oxide composites had superparamagnetic behaviour at room temperature.
