Regulatory and Controlling Mechanisms on UAV/UAS that Influence Efficient Architectural Heritage Praxis: Actual Situation in Serbia

Worldwide quickly enacted UAV/UAS legislative is permanently improving to prevent unpredicted and potentially hazardous activities. Serbian regulations have generally been harmonized with those of the EU and strictly implemented. This Paper investigates Serbian regulatory mechanisms negatively affecting surveying effectivity/efficiency. Respecting the methodology, valorisation criteria are set and problems identified. Research results are graphically presented to mutually compare them and obtain sustainable conclusions

Encoding/Decoding Capitals of Classical Architectural Orders by Using Fractal Geometry: Establishing Methodology

In most cases, artefacts are differentiated in terms of style they belong to – mainly visually, not mathematically. So, the main research questions of this study are both how to numerically encode stylistic regularities (peculiarities) as geometric indicators of artefacts morphology and how to decode them, namely to identify architectural style those artefacts belong to. Columns, namely their capitals are chosen as the most distinctive elements among artefacts. To elaborate on the validity of the defined principles of the aim-related methodology, a few representatives (capital samples) from each of three fundamental classical architectural orders (Doric, Ionic, and Corinthian) are used. The subject of this Paper is to establish relevant indicators of capital qualification, capital classification, and thus, referred architectural order identification. The verification of those indicators is performed by processing two sets of capitals contours (that belong to the mutually equidistant transverse and equiangular radial section planes) of each of the selected samples (namely digital 3D models). The narrower research aim is to point out that it is possible to encode not only chosen but also any other capital – by using the mentioned indicators of fractal and non-fractal nature (as a control one). The wider research aim refers to a possibility to identify order a concrete fragment of capital belongs to in terms of recognising it computationally (as confidently as possible from the mathematical probability point of view) based on the established research methodology principles. Finally, it is possible to conclude that changes of the analysed indicators trendlines behaviour (expressed by changes of its slope, roughness, continuation, etc.) accurately/precisely describe morphology-wise variations of a form that could point out subject-related stylistic variation, as well. So, this Paper demonstrates not only the fact that architectural orders capitals are true fractal objects, but rather how fractal analysis as a tool can be used to scientifically numerically encode/decode their certain characteristics (fractal features) of single- or multi-scale nature

Assessing public open spaces in Belgrade – a quality of urban life perspective

Purpose: This paper interrogates the impact of spatial transformations on urban life. It explores the level of individual and group satisfaction and sense of well-being within the urban public realm; this is undertaken by reporting on the outcomes of an assessment study of three key public open spaces in Belgrade, developed from a quality of urban life (QoUL) perspective. Design/methodology/approach: A systematic multilevel assessment method is utilised, with the aim of determining the material and immaterial elements that can contribute to an individual's sense of comfort within a public space. The study places emphasis on the functional, social and perceptual attributes as they relate to the physical characteristics of three assessed spaces. Findings: The assessment study resulted in a systematic overview of the different attributes of the three assessed spaces. With various performance levels within each set of attributes, the study identifies key challenges and problems that could lead towards determining possible opportunities for future local urban interventions and developmental actions. Originality/value: With the shifts in policies and the associated governance process that redefined the outlook of previously enforced development and urban growth in the last two decades, the capital of Serbia, Belgrade, has undergone significant spatial changes. This has resulted in a certain level of fragmentation in the urban fabric, leading to a number of challenges concerning public health, well-being, safety, accessibility, comfort and urban mobility, to name a few, that need to be better addressed and understood within the local context

STRUCTURE AND CHARACTERIZATION OF BaTiO3-Ni(1-x)Zn(x)Fe2O4 COMPOSITES

NiZnFe2O4 (NZF) powder was prepared by auto-combustion method starting from nickel, zinc and iron nitrates. Thermal treatment was performed at 1000 oC for 1 h after which the nickel ferrite powder was formed. Barium titanate (BT) powder was prepared with same method using titanyl nitrate and barium nitrate as a starting reagents. Multiferroic composites with formula BaTiO3– Ni(1-x)ZnxFe2O4 (x = 0.3, 0.5, 0.7) were prepared by mixing chemically obtained NZF and BT powders in the planetary mill for 24 h. Powders were pressed and sintered at 1170 oC for 4 h. Samples were characterized by XRD, Raman, SEM, IR. Magnetic and electrical measurements were also carried out. X-ray and Raman measurements confirmed the presence of NZF, BT phases and the traces of barium ferrite phase. The microstructure of the ceramics shows (Fig. 1.) the formation of polygonal (NZF grains), rounded (BT grains) and plate like grains (barium ferrite phase). The impedance analyses of multifferoic composites at 200 ºC have shown the contribution of both, grain and grain boundary resistivity

Raman study of Ba-doped ceria nanopowders

A series of Ce1-xBaxO2-y (5 LT = x LT = 0.20) nanometric powders were synthesized by self-propagating room temperature synthesis. XRD and Raman scattering measurements were used to characterize the samples. at room temperature. All the samples are solid solutions with fluorite type structure with an average crystallite size about 5 nm. The redshift and asymmetric broadening of the Raman F g mode can be well explained with combined confinement and strain effects because of the nanocrystalline powders nature. The appearance of the additional peaks at similar to 560 cm(-1) and similar to 600 cm(-1), are attributed to extrinsic and intrinsic O2- vacancies in ceria lattice. Raman spectra of temperature treated Ce0.80Ba0.20O2-delta sample revealed the instability of this system

MOLNUPIRAVIR COMPARED TO NIRMATRELVIR/RITONAVIR FOR COVID-19 IN HIGH-RISK PATIENTS WITH HAEMATOLOGICAL MALIGNANCY IN EUROPE. A MATCHED-PAIRED ANALYSIS FROM THE EPICOVIDEHA REGISTRY

Introduction: Molnupiravir and nirmatrelvir/ritonavir are antivirals used to prevent progression to severe SARS-CoV-2 infections, which reduce both hospitalization and mortality rates. Nirmatrelvir/ritonavir was authorised in Europe in December 2021, while molnupiravir is not yet licensed in Europe as of February 2022. Molnupiravir may be an alternative to nirmatrelvir/ritonavir, because it displays less frequent drug-drug interactions and contraindications. A caveat connected to molnupiravir derives from the mode of action inducing viral mutations. In clinical trials on patients without haematological malignancy, mortality rate reduction of molnupiravir appeared less pronounced than that of nirmatrelvir/ritonavir. Little is known about the comparative efficacy of the two drugs in patients with haematological malignancy at high-risk of severe COVID-19. Thus, we here assess the effectiveness of molnupiravir compared to nirmatrelvir/ritonavir in our cohort of patients with haematological malignancies. Methods: Clinical data of patients treated either with molnupiravir or nirmatrelvir/ritonavir monotherapy for COVID-19 were retrieved from the EPICOVIDEHA registry. Patients treated with molnupiravir were matched by sex, age (±10 years), and baseline haematological malignancy severity to controls treated with nirmatrelvir/ritonavir. Results: A total of 116 patients receiving molnupiravir for the clinical management of COVID-19 were matched to an equal number of controls receiving nirmatrelvir/ritonavir. In each of the groups, 68 (59%) patients were male; with a median age of 64 years (IQR 53-74) for molnupiravir recipients and 64 years (IQR 54-73) for nirmatrelvir/ritonavir recipients; 57% (n=66) of the patients had controlled baseline haematological malignancy, 13% (n=15) stable, and 30% (n=35) had active disease at COVID-19 onset in each of the groups. During COVID-19 infection, one third of patients from each group were admitted to hospital. Although a similar proportion of vaccinated patients was observed in both groups (molnupiravir n=77, 66% vs nirmatrelvir/ritonavir n=87, 75%), those treated with nirmatrelvir/ritonavir had more often received four doses (n=27, 23%) as compared to patients treated with molnupiravir (n=5, 4%, p<0.001). No differences were detected in COVID-19 severity (p=0.39) or hospitalization (p=1.0). No statistically significant differences were identified in overall mortality rate (p=0.78) or in survival probability (d30 p=0.19, d60 p=0.67, d90 p=0.68, last day of follow up p=0.68). In all patients, deaths were either attributed to COVID-19 or the infection contributed to death as per treating physician's judgement. Conclusions: In high-risk patients with haematological malignancies and COVID-19, molnupiravir showed rates of hospitalization and mortality comparable to those of nirmatrelvir/ritonavir in this matched-pair analysis. Molnupiravir appears to be a plausible alternative to nirmatrelvir/ritonavir for COVID-19 treatment in patients with haematological malignancy

Obstetric and gynecological intervention in women with Bernard-Soulier syndrome: Report of two cases

Introduction. Bernard-Soulier syndrome (BSS) is a rare inherited bleeding disorder characterized by giant platelets thrombocytopenia e prolonged bleeding timee frequent hemorrhages with considerable morbidity. Data on the outcome of pregnancy and gynecological intervention in BSS are rare and there are no general therapeutic recommendations. Cases Outline. We report two cases of BSS. In the first case a 29-year-old patient with BSS was admitted in 8 weeks of gestation. The diagnosis of BSS was made on the basis of prolonged bleeding time, giant-platelets thrombocytopenia, and absent ristocetin-induced platelet aggregation. In 38 week of gestation Cesarean section, with platelets transfusion preparation, was performed. Obstetric intervention passed without complication. Postoperative course was complicated with a three-week vaginal bleeding resistant to platelet transfusion. Neonate platelet count was normal. Our second case was a 28-year-old patient with BSS, hospitalized for ovarial tumor surgery. The patient was prepared for the intervention with platelets transfusion. The surgery was uncomplicated, but on the second postoperative day a massive vaginal bleeding, resistant to the platelet transfusion, developed. Bleeding control was achieved with activated recombinant factor VII. Twelve hours the patient developed later hypertensive crisis with epileptic seizure due to subarachnoid hemorrhage. Therapy was continued with platelet transfusion, antihypertensive and antiedema drugs. PH examination of tumor tissue showed hemorrhagic ovarial cyst. Conclusion. Obstretic and gynecological intervention in women with BSS may be associated with a life-threatening bleeding thus requiring a multidisciplinary approach with adequate preparation. Because of the limited data in the literature, it is not possible to provide firm management recommendations and each case should be managed individually
