Sebastijan Robič, Aljoša Šajna, Lucija Hanžič, Alisa Machner, Marie Helene Bjørndal, Klaartje De Weerdt, Yushan Gu, Benoit Bary, Rosamaria Lample, 2021, objavljeni znanstveni prispevek na konferenci

Povzetek: The design process of concrete structures is carried out using standards and guidelines, while the durability predictions of concrete structures is supported only with exposure classes and experience-based requirements. To improve durability predictions of the carbonation resistance of concrete, a numerical model is being developed within the Horizon 2020 project EnDurCrete, coupling the rate of carbonation, and the drying rate. To verify the numerical model, an accelerated carbonation study was carried out. Experiments were conducted on mortars incorporating a novel CEM II/C (S-LL) cement, developed within the EnDurCrete project, and a commercially available reference cementCEM II/A-S. EnDurCrete mortars (EnM) and reference mortars (RefM) were prepared with water-cement ratios of 0.6 and 0.5 (denoted with label extensions -06 and -05). Visual assessments and thermogravimetric analysis (TGA) were used to measure the carbonation rates, which were found to be ~1.0 mm day-0.5 in EnM-06 and ~0.6 mm day-0.5 in RefM-06, while in EnM-05 and RefM-05 the values were ~0.7 and ~0.2 mm day-0.5 respectively. Additionally, TGA shows that the initial portlandite (CH) content is ~1.5 wt% in EnM-06 as opposed to ~3.0 wt% in RefM-06. The difference in the initial CH content in the two hydrated binders might explain the difference in their carbonation rate. During the moisture transport experiments a gravimetric method was used to determine mass changes as specimens underwent drying and resaturation with and without CO2 present. The drying led to a decrease in mass, but in the presence of CO2 this mass loss was compensated by the mass gain due to uptake of CO2 during carbonation. The resaturation experiments indicate an increase in the suction porosity in the carbonated samples compared to the non-carbonated samples.

Mud from the Sitarjevec mine as a pigment for textile printing
Darja Rant, Mateja Štefančič, Vesna Zalar Serjun, Mateja Golež, 2021, objavljeni znanstveni prispevek na konferenci

Povzetek: The Sitarjevec mine, located near the town of Litija (Central Slovenia), is recognized by the strong yellow colour of its dripstone structures and mine mud deposits. The mine mud, composed predominantly of goethite, accumulates on the ground of the mine shafts as the result of the interaction between percolating underground water, iron ore minerals and microorganisms. Since the accumulation of limonite mine mud is an ongoing process, larger quantities of mud have been deposited in the mine shafts since its closure. These deposits present a real threat of unleashing a mine mud spill on the town of Litija. Such a scenario has already previously occurred. In order to find new potential routes for recycling larger quantities of this mine mud, the present research work was performed to assess the use of mine mud as a pigment in the dye industry. In the first stage, the chemical (XRF) and microstructural (SEM) characteristics of the mine mud were defined together with the identification of its phase composition (XRD), particle size distribution and specific surface area (BET). Furthermore, the pigment was used to colour textile printing paste on a laboratory scale. To define the most appropriate quality of textile prints the rheological response of the various textile printing paste samples was investigated in terms of their plastic viscosity, indicating their suitability for use in textile printing. Test prints wereconducted, and the properties of leaching and fastness in the prints were assessed.

Strictures of the male urethra: how to perform and evaluate radiourethrography and sonourethrography to avoid mistakes
Darja Babnik-Peskar, Alenka Višnar-Perovič, 2000, izvirni znanstveni članek

Povzetek: Introduction. Precise evaluation of the uretheral stricture localisation, length, depth and quality of wall changes are necessary for the selection of the optimal treatment to prevent recurrences. Decision for urethral dilatation, internal urethrotomy or open surgery depends on urethroscopic, radiourethrographic-RUG, and recently, according to MC Annich, also sonourethrographic-SUG results. SUG adds information about the depth and density of spongiofibrosis. Previously published findings of RUG length underestimation, compared to SUG and endoscopy, were responsible for inappropriate treatment and recurrences. In our article, we evaluate SUG as a new imaging method in the diagnosis of uretheral strictures and treatment planning, and describe both imaging methods together with usual pitfalls in performance or interpretation, possible reason for incorrect length measurements, and RUG length underestimation. Patients and methods. In the period of 20 months, we evaluated SUG compared to RUG and endoscopy in 51/130 males with suspected urethral strictures. Results. Compared to RUG, sonographywas correct in 92% radiographycally detected strictures. Length measurements by sonography were 22% shorter than radiographic lengths, which could be explained by radiographic magnification, as it was proved with wire measure placed on penis. Considering radiographic magnification, we did not find important differences in any measurement. Opposite to previously published RUG results compared to endoscopy and SUG, radiographic length underestimation was not found. Conclusions. The combination of both imaging methods provides optimal information about urethral stricture anatomy. We conclude that published radiographic length underestimation could be only a misinterpretation. (Abstract truncated at 2000 characters).

Assessment of social effects in asset management
Darko Kokot, Alfred Weninger-Vycudil, 2021, objavljeni znanstveni prispevek na konferenci

Povzetek: The transnational European CEDR project ISABELA (Integration of social aspects and benefits into lifecycle asset management) was launched to define a common basis for social impact assessment in asset management. The aim was to define a holistic asset management framework for social key performance indicators (S-KPIs) and to model social benefits in terms of social effects (monetary and non-monetary), social backlog and social risk. These project results are becoming increasingly important in the context of evaluating different maintenance strategies for road infrastructure networks. While decision makers need to present the consequences of their maintenance strategies and policies on both technical and social levels, ISABELA showed how social aspects can be an integrated part in asset management frameworks, how to present social impacts and how to discuss maintenance needs using social aspects. The project aimed to identify clear and justifiable social key performance indicators in combination with existing technical parameters, taking into account different stakeholders and their needs and expectations. To this end, ISABELA considers maintenance aspects such as traffic availability, disturbance and efficiency (travel time, vehicle operating costs, etc.), road safety (fatal and serious accidents related to asset condition), environment (noise, air pollution, natural resources, etc.) and socio economy (asset value, wider social effects, etc.). In addition to the S-KPIs, ISABELA proposed a decision-making process for the selection of appropriate parameters and models, and demonstrated the assessment of social effects with practical examples.

Renal cell carcinoma in the ectopic kidney prospects of diagnosting and treatment of the carcinoma of the kidney: case report
Erika Brenčič, Marjeta Stanovnik, Mojca Glušič, 2000, strokovni članek

Povzetek: Background. An extensive use of ultrasonography and computed tomography have enormously contributed to the early detection of adenocarcinoma of kidney taking into consideration that they have been so far often detected by chance.In addition to provide us with an image of a tumor and contributing to define more easily the nature of tumor, MRI is most helpful in detecting the infiltrations of tumor into its surroundings and changes in the veins. Case report. This case report presents the patient with adenocarcinoma of the ectopic kidney. The ultrasonography, computed tomography and magnetic resonance imaging detected and abundant non-homogenous tumor mass in pelvis minor. Additionally to the suspected ectopia of one of the kidney, it was alsosuspected that there was another pathological process of different etiology too. This suspicion was based on the detection of a different tumor mass in between the intestinal loops. Two months after the nonradical excisionof the adenocarcinoma from the ectopic kidney, the following changes were observed: progress of the residual tumor in the pelvis minor and the tumor in between the intestinal loops (that was not removed during the first operation). The patient was given immunochemotherapy and local radiotherapy. Conclusions. According to the available data in literature, the localization of tumor in ectopic kidney is extremely rare.

The role of sonographic evaluation of spinal canal in children
Živa Zupančič, 2000, pregledni znanstveni članek

Povzetek: Background. Spinal sonography is a valuable diagnostic imaging modality as it has the ability to demonstrate good anatomic detail of the spinal canal, its contents, and the surrounding structures. The examination technique, the anatomy of the cord, the most common anomalies, and the evaluation of the sonography compared to magnetic resonance imaging are presented. Conclusions. Spinal sonography is recommended as the primary imaging modality for congenital anomalies of the lower spine in infants and as the screening modality for closed spinal dysraphism in infants and small children. The examination technique, the anatomy of the cord, the most common anomalies, andthe evaluation of the sonography compared to magnetic resonance imaging arepresented.
