Authors: Gorzelańczyk Tomasz , Schabowicz Krzysztof 
Published: February 2025

Abstract
This study presents tests for determining the thickness and compressive strength of unilaterally accessible concrete components of a building, which in this case is a cable-supported building (referred to as Trzonolinowiec) located in Wroclaw, Poland. Nondestructive test methods, the ultrasonic tomography method and the sclerometric method, were used for the tests. The thickness of the unilaterally accessible core of the building was determined using the ultrasonic tomography method. An analysis of the images obtained in this way showed that the thickness of the core’s concrete wall varies along the height of the building. The largest core wall thickness, amounting to 350–400 mm, was detected at a height between the ground floor and the first floor. At a height between the first floor and the second floor, the wall thickness amounts to 280–300 m. For the next floors, wall thickness ranges from 140 to 200 mm. It should be noted that the specified thicknesses of the core wall clearly decrease with the height of the building. On the last floor, the lowest ones were specified, in the range of 140–160 mm. The ultrasonic tomography method was found to be highly useful for determining the thickness of unilaterally accessible concrete members. The sclerometric tests carried out on the concrete walls of the building’s core clearly showed a slight variation in the compressive strength of the concrete. In most of the measuring points, the concrete was found to be a class of C12/15. In a few places the concrete was found to be a class of C16/20. The results of the nondestructive testing were used to build a BIM model of the Trzonolinowiec building and for structural calculations. The test results turned out to be very interesting and of critical importance for the further use of this building. The research conducted by the authors showed that the selected non-destructive methods proved useful for assessing the strength of concrete and the thickness of the concrete wall of the core. Based on the obtained results, it was possible to model the thickness of the core using BIM and then perform structural and strength analyses. The obtained results should be assessed in the category of input data that can be used in later analyses. In this aspect, it can be considered a small contribution to the progress in the use of non-destructive testing in future modeling applications.

Published: February 2025

Abstract
Desalination is a crucial process in addressing the global water scarcity crisis. Among the various techniques available, pervaporation has emerged as a promising method due to its energy efficiency and high separation performance. The purpose of this research was to create a polyethersulfone (PES) membranes with high permeability and enhanced hydrophilicity. The membranes for pervaporation (PV) desalination were prepared using the phase inversion technique. PES membranes were fabricated from different concentrations while maintaining constant preparation conditions. These membranes were characterized using Zeta potential analysis, Fourier transform infrared (FTIR) spectroscopy, field-emission scanning electron microscopy (FESEM), X-ray diffraction spectroscopy (X-ray), atomic force microscope (AFM) and thermogravimetric analysis (TGA). A permeate flux of 0.05 L/m2 h and rejection percentage of 91 % were observed using PES 8 membrane from feed concentration 7,090 ppm. Reusability of PES membranes were tested our three cycles for desalination. The model equation was derived for salt rejection using the Box-Behnken model of response surface methodology (RSM). However, the experimental study revealed that the model suited the data perfectly. This study highlights the excellent potential of these PES membranes for treating salt solutions.

Abstract

Background information
Delayed graft function (DGF), defined as the need for dialysis within the first week of a kidney transplant, is a common complication, particularly in extended criteria donor transplants, where its incidence ranges from 21 to 31%.

Objectives
We observed a prolonged case of DGF in a 47-year-old patient with chronic kidney disease (CKD) resulting from diabetic nephropathy. The patient, classified in a moderate immunologic mismatch group, received a marginal deceased donor kidney.

Results
For the first 4 weeks post-transplantation, graft function was impaired. After 29 days of anuria, the transplanted kidney began to recover. The literature review found few clinical cases of DGF extending beyond 1 month. Our patient had several risk factors for DGF, including diabetes mellitus, pre-transplant hemodialysis, and moderate immunologic mismatch. Additionally, the marginal graft increased the risk of ischemia-reperfusion injury and glycocalyx damage. However, it remains unclear how these factors influenced the duration of DGF. The exact cause of the extended DGF in this case remains unknown. Although the literature identifies key risk factors for DGF, data on factors leading to prolonged kidney dysfunction are lacking. Therefore, decisions to remove a non-functioning transplanted kidney should not be made hastily.

Abstract
Europium-doped nanocrystals constitute a promising material for a scalable future quantum computing platform. Long-lived nuclear spin states could serve as qubits addressed via coherent optical transitions. In order to realize an efficient spin-photon interface, we couple the emission from a single nanoparticle to a fiber-based microcavity under cryogenic conditions. The spatial and spectral tunability of the cavity permits us to place individual nanoparticles in the cavity, to measure the inhomogeneous linewidth of the ions, and to show a multi-modal Purcell-enhancement of two transition in Eu3+. A halving of the free-space lifetime to 1.0 ms is observed, corresponding to a 140-fold enhancement of the respective transition. Furthermore, we observe a narrow optical linewidth of 3.3 MHz for a few-ion ensemble in the center of the inhomogeneous line. The results represent an important step towards the efficient readout of single Eu3+ ions, a key requirement for the realization of single-ion-level quantum processing nodes in the solid state.

Published: February 2025

Abstract
To improve heat dissipation performance of panel-type radiator for transformers, this study investigated the flow and heat transfer characteristics in the air-side metal foam partially filled channels of the radiator. The porous thin-layer filled (PTLF) and porous fin filled (PFF) methods and the filling ratio (V
p) were analyzed and compared. The result indicated that the permeability and interfacial turbulent kinetic energy in the porous region of PFF channel are higher. Increasing V
p can promote flow mixing and heat transfer. For Re = 5,125–15,375, when V
p = 11.1%, the performance evaluation criterion in PFF channel can increase by 12.0–30.8% as compared with PTLF channel. Then, the effects of metal foam material, porosity (φ), and pore density (ω) were explored. The results show that decreasing φ, increasing ω, and using copper metal foam are all beneficial for enhancing the heat transfer performance of the PFF channel within the range studied. Finally, when V
p = 11.1%, the PFF channels filled with Cu-10-9.5 and Al-10-9.7 samples were selected for comparison with previous related studies, which demonstrated the feasibility of the metal foam partial filling method on the air side of the panel-type radiator.

ИСПОЛЬЗОВАНИЕ МАТРИЦЫ ВЯЗКОСТИ ПРИ КОНСТРУИРОВАНИИ ЧИСЛЕННОГО РЕШЕНИЯ ЗАДАЧИ РИМАНА ДЛЯ УРАВНЕНИЙ СПЕЦИАЛЬНОЙ РЕЛЯТИВИСТСКОЙ ГИДРОДИНАМИКИ

Published: February 2025

Традиционно для решения уравнений гидродинамики используется метод Годунова, основной составляющей которого является решение задачи Римана для вычисления потока консервативных переменных через границу соседних ячеек. Большинство численных схем решения задачи Римана основаны на частичном или полном спектральном разложении матрицы Якоби при пространственной производной. Однако при использовании сложных гиперболических моделей и различных видов уравнения состояния даже частичное спектральное разложение найти аналитически достаточно сложно. К таким гиперболическим системам можно отнести уравнения специальной релятивистской магнитной гидродинамики. В работе предложена численная схема решения задачи Римана с использованием матрицы вязкости, построенной на основе полиномов Чебышева. Такая схема не требует информации о спектральном разложении матрицы Якоби, при этом учитывая в своей конструкции все виды волн. Для уменьшения диссипации численного решения была использована кусочно-параболическая реконструкция физических переменных. На классических тестовых задачах исследовано поведение разработанной численной методики.
Traditionally, to solve the hydrodynamic equations a Godunov method is used, whose main component is the solution of a Riemann problem to compute the fluxes of the conservative variables through the interfaces. Most numerical Riemann solvers are based on partial or full spectral decompositions of the Jacobian matrix with the spatial derivatives. However, when using complex hyperbolic models and various types of equations of state, even partial spectral decompositions are quite difficult to find analytically. Such hyperbolic systems include the equations of special relativistic magnetic hydrodynamics. In this paper, a numerical Riemann solver is constructed by means of a viscosity matrix on the basis of Chebyshev polynomials. This scheme does not require information about the spectral decomposition of the Jacobian matrix, while considering all types of waves in its design. To reduce the dissipation of the numerical solution, a piecewise parabolic reconstruction of the physical variables is used. The behavior of the numerical method is studied by using some classical test problems.

Published: February 2025

AbstractAronia melanocarpa, a main constituent of black chokeberry, provides a rich source of bioactive molecules including polyphenols, flavonoids, and anthocyanins and has been used for long in traditional medicine due to its various health-promoting and disease-alleviating properties. The aim of our literature survey was to provide an actual update of evidence regarding the antibacterial activities exerted by Aronia melanocarpa and its potential application for the treatment of human bacterial pathogenic including food-borne infections. Our survey revealed that distinct ingredients in Aronia melanocarpa do not only inhibit growth of Gram-positive and to a lesser extent of Gram-negative bacteria, but also biofilm formation that is even more pronounced upon combined application. Furthermore, the anti-microbial effects against food-spoiling bacteria underscores the application of defined Aronia-derived molecules in food preservation decreasing the risk for transmission of food-borne pathogens and thereby, improving food safety. Notably, in vivo studies revealed that prophylactic Aronia juice application alleviated murine Listeria monocytogenes-induced enteritis, dampened growth of streptococci involved in dental caries development, and decreased the incidence of urinary tract infections in nursing home residents. In conclusion, Aronia-derived bioactive molecules exhibit promising anti-bacterial and disease-alleviating effects that should be further elucidated in clinical studies.
The laboratory diagnosis of typhoid fever
Authors: Bamford Colleen 
Published: February 2025

Typhoid fever is a serious bacterial infection. Given its non-specific clinical presentation the laboratory diagnosis is critical. This article discusses existing and potential diagnostic methods. Culture particularly of blood remains very important but needs to be optimised in terms of volume and timing. Existing serological tests including the outdated Widal test and other serological tests generally lack sufficient sensitivity and specificity, though newer serological tests detecting immunoglobulin A to lipopolysaccharide, haemolysin E and other novel antigens, hold potential. Multiplex polymerase chain reaction on blood following a short pre-enrichment step also appears to offer excellent sensitivity and specificity but may be more suitable for research studies at this stage. The limitations of blood culture as the existing reference method are noted, and alternatives discussed.

Ralstonia species are more frequently being recognised as causative agents of serious healthcare-associated infection especially among immunocompromised individuals. Ralstonia species are environmental, non-fermenting, aerobic, Gram-negative bacilli typically found in water and soil. Ralstonia mannitolilytica, Ralstonia pickettii and Ralstonia insidiosa have been responsible for human infections such as bacteraemia and bone infection. Central nervous system infection and infection in immune competent individuals are uncommon. We report a case of ventriculoperitoneal shunt infection and meningitis caused by R. mannitolilytica in an immune competent 11-month-old female.

Introduction: Rehabilitation therapists are expected to manage upper extremitiy difficculties following stroke by using effective treatment approaches. Constrant-induced Movement `Therapy (CIMT) facilitates upper extremity functional recovery in patients after stroke. However, in South Africa, its application is not well document.
Aim: To assess and compare the knowledge and perception of occupational therapists and physiotherapists on the use of CIMT for stroke rehabilitation in South Africa.
Methods: A descriptive, cross-sectional design using a self-administered online questionnaire was distributed via the two professional associations. Data were analysed descriptively and the Mann-Whitney U and Kruskal Wallis tests were used to make inferences.
Results: Of the 108 respondents, 49.1% (n=53) were occupational therapists, and 50.9% (n=59) were physiotherapists. A higher level of education (p=0.037) and working specifically with stroke patients (p=0.050) are significantly associated with better CIMT knowledge and perception. The profession of the participants was not significatly associated with their knowledge and perception of CIMT.
Conclusion: This study demonstrates gaps in the knowledge of CIMT as a treatment technique for upper extremity impairment following stroke. Although most respondents were aware of CIMT, improved guidance and knowledge of CIMT are required to remediate knowledge gaps. This may assist in improving the feasibility of CIMT and thus promote its clinical application, given the prevalence of upper extremity impairment in stroke patients managed by therapists.
