Published: August 2023

Within the framework of the policy of “decarbonization” of the economy, a technology for hydrogen producing from local fuels (LF) and combustible waste of human activity is proposed as a part of the development of the functionality of heating cycles of energy production. The aim of the present study is to evaluate the energy efficiency of a steam-powered mini-CHP plant operating on local fuels with a thermochemical hydrogen production module. A brief literature review of thermochemical cycles of hydrogen production is presented, and it is shown that hybrid copper-chlorine Cu–Cl cycles are recognized as the most promising. In the Aspen Hysys software environment, a mathematical model of a mini-CHP plant with a five-stage hydrogen production cycle was synthesized, which can later be used as a component in the digital twin. According to the results of the analysis of the mathematical model, it was determined that the specific consumption of electric energy per 1 kg of hydrogen for such a scheme will be 9.11 (kW×h)/kg, which is on average more than five times less than in the production of hydrogen by electrolysis, the rest of the required energy is replaced by thermal one, while the maximum fuel utilization factor of mini-CHP with a hydrogen production module using wood waste as fuel amounted to 83.1 %, including a thermal efficiency of 51.5 %, the efficiency of hydrogen production at the lowest calorific value is 31 %, the electrical efficiency for the supply of electricity to the grid is 0.6 %. For comparison, the maximum fuel utilization of a steam-powered mini-CHP of the same electrical capacity reaches 90.9 %. The expansion of mini-CHP options operating on local fuels by introducing a hydrogen production unit by hybrid thermochemical method into its scheme makes it possible to increase the maneuverability of the station, which implies the possibility of organizing the operation of mini-CHP in accordance with the requirements of thermal consumers and electrical graph-reducing the loads of the power system during the hours of maxima and minima of its consumption by changing the electrical power supply to the network or increasing the power consumption of electricity from the external network to the power required for hydrogen production. In conclusion, the possibility of developing the studied scheme of a mini-CHP operating on local fuels towards further utilization of combustion products in order to generate artificial natural gas, which in this case can be called “green”, is indicated.

The influence of the composition of saturating mixtures with standard zinc powder and zinc dust on the change in the size and weight of the samples was studied under laboratory conditions. It is shown that with an increase in the amount of the zinc component in the composition of the saturating mixture in the form of zinc powder (Znst) or hot‑dip galvanizing waste‑zinc dust (Znotx), the thickness of the galvanized product also increases. The obtained graphic dependences of the growth of the thickness of the samples on the amount of zinc components have the same pattern of change. It is also shown that with an increase in the zinc component in the composition of the saturating mixture in the form of zinc powder (Znst) or hot‑dip galvanizing waste – zinc dust (Znotx), the mass of the galvanized product also increases. The graphic dependences of the growth of their mass on the amount of different zinc components also have the same character of change.It has been established that the most intensive character of the growth in the values of the size and mass of the product is observed when the content of the zinc‑containing component in the mixture is more than 60 % for both saturating media, whether in the Znst‑Al2O3 or Znout‑Al2O3 medium. At the same time, products galvanized in a saturating Znst‑Al2O3 medium have large dimensions and masses.

The rheological properties of the alloy E125 (Zr‑2.5 %Nb) were studied in the range of deformation rates 0.5–15 s‑1 and the temperature range 20–770 °C. A database for computer FEM modeling was created in the specified temperature and speed ranges. In the DEFORM‑3D software package, numerical simulation of a complex radial shear rolling process was carried out using the obtained database. The conditions conducive to the grinding of the alloy structure into an ultrafine‑grained state were determined. Based on the simulation results, a full‑scale experiment of rolling a bar made of alloy E125 on a radial shear rolling mill RSP‑14/40 in 7 passes from a diameter of 37 mm to 20 mm with a total compression in diameter of ε = 85 % was carried out. At the same time, according to the modeling, the total accumulated deformation in the most developed peripheral zone was 27,5 mm/mm. Due to the complex vortex flow of the metal, the distribution of accumulated deformation over the cross section was uneven with a gradient to the axial zone. This should also affect the change in the structure. The changes and the gradient of the structure were studied by the method of EBSD mapping of the sample section with a resolution of 2 mm. The microhardness gradient of the cross section was also investigated by the HV method. The axial and central zones of the sample were studied on the. The structure has a pronounced gradient from the formed equiaxed ultrafine‑grained (UMZ) structure on several outer millimeters of the peripheral section to an elongated rolling texture in the center of the rod. The work shows the possibility of processing with the formation of a gradient structure with enhanced properties for the E125 alloy, and also presents a database for FEM calculations.

Study of the stress field in a plastic imprint and around it is of great practical importance. Processes similar to indentation are used in shot blasting to harden the surface of materials and generate compressive stresses in the surface layers. The purpose of this work was to study the change in the stress-strain state in the area of the plastic imprint with increasing load, in the transition from small to large deformations, as well as to study the change in stress at different strain rates.X-ray diffraction method was used to study the field of residual stresses generated on the surface of a plastically deformed region – in the zone of an imprint formed when a spherical indenter is pressed into the metal. An analysis of the change in the stress distribution with increasing load in the range of plastic imprint depths of 10–60 µm for steels and aluminum was made. Influence of the loading rate on the change in the values of residual stresses under normal contact of colliding bodies was studied. It is shown that the stress distribution has a complex character with areas of compression and tension of the metal and is determined by the ratio of the indentation depth to its diameter.The obtained experimental data make it possible to determine the choice of optimal modes of shot blasting, including for increasing the endurance limit of products.

. The paper presents the results of experimental studies of the hydrodynamics of the coolant in the core of the PWR reactor with fuel assemblies “TVS-Kvadrat” of various designs. Experimental studies of hydrodynamics consisted in studying the velocity fields and the process of cross-flow of coolant between adjacent fuel assemblies “TVS-Kvadrat” of various designs in homogeneous and mixed cores on large-scale experimental models, including fragments of two adjacent fuel assemblies “TVS-Kvadrat” and a gap between them. The test models differ in the number of installed grids, this is due to the fact that in a homogeneous core the hydraulic load along the height of the fuel assemblies is identical, and in a mixed core the hydraulic load is uneven due to the different number of installed grids. The hydrodynamics of the coolant has been studied on an aerodynamic open-loop based on the theory of hydrodynamic similarity, using individually calibrated pneumometric sensors. Based on the data obtained, the fields of local axial and transverse velocities in various sections along the length of the studied section of the test models have been constructed. The fields of local dimensionless transverse and axial flow velocities in the fuel bundles and the gap between the fuel assemblies “TVS-Kvadrat” of the PWR reactor core have been studied. Peculiarities of the process of transverse flow between adjacent “TVS-Kvadrat” of a homogeneous and the mixed core of the PWR reactor have been revealed. The results of experimental studies have been transferred to the developer of “TVS-Kvadrat”, that is JSC “Experimental Design Bureau of Mechanical Engineering named after I. I. Afrikantov”, for further use in justifying the design and operating modes of a nuclear power plant.

Abstract
The disorders of glucolipid metabolism are prevalent in patients with type 2 diabetes
mellitus (T2DM). Since the effects of Palmitic-Acid-Hydroxy-Stearic Acid (PAHSA)
on T2DM were not fully understood, the study aimed to investigate the role of S-9-
PAHSA in diabetes and the possible mechanisms. Male C57BL6 mice were fed with a
high-fat diet (HFD) and injected with streptozotocin (STZ) to establish the diabetic
mice model, and then administered with low- or high-dose S-9-PAHSA. Insulin,
glycosylated serum protein (GSP), glucagon-like peptide-1 (GLP-1), and oxidized lowdensity
lipoprotein (ox-LDL) were assessed by ELISA. SH-SY 5Y cells were incubated
in a diabetic environment and treated with S-9-PAHSA, R-9-PAHSA, or 9-PAHSA.
Cell viability, cell proliferation, apoptosis, lactate dehydrogenase (LDH), and reactive
oxygen species (ROS) were measured by corresponding kits. Protein expressions were
determined by western blot. The results showed high-does S-9-PAHSA improved
insulin resistance and lowered ox-LDL. Compared with the control group, the
significantly up-regulated expression of p62 and down-regulated expression of beclin
1 were found in diabetic mice and could be reversed by S-9-PAHSA. In vitro, S-9-
PAHSA increased cell viability and proliferation while reducing LDH and ROS. S-9-
PAHSA could reduce the expression of cleaved caspase-3 and TUNEL-positive cells,
and increase the ratio of LC3II/I after high glucose and fatty acid stimulation in vitro.
Downward trends were observed in PI3K and the phosphorylation of AKT in diabetic
environments, which could be slightly restored by S-9-PAHSA. In conclusion, S-9-
PAHSA could regulate glycolipid metabolism both in vivo and in vitro, indicating the
vital role of S-9-PAHSA in T2DM.

Abstract
BACKGROUND: In the summer of 2021, the Swiss Society for General Internal Medicine (SGAIM) published six quality indicators for the inpatient sector for the first time. The aim of these indicators is to facilitate a structured quality improvement process in internal medicine. The present implementation study examines the practicability of the quality indicators recommended by the SGAIM.
METHODS: Using the QUALIFY assessment tool for quality indicators, the SGAIM indicators are structurally evaluated using the example of Hospital Männedorf. Within this framework, a retrospective data analysis of the years 2020 and 2021 was carried out.
RESULTS: The results were calculated according to the recommended evaluation intervals and were as such: A provisional discharge report within 24 hours was sent to the follow-up institution for an average of 23.7% of discharges. A new prescription of benzodiazepines in patients with an age of ≥65 years occurred in an average of 17.2% of patients per month. The fall history was collected from 100% of the patients. The monthly proportion of patients with transfusions with an Hb value of >8g/dl was 17.9% on average. The proportion of CIRS cases per patient averaged 1.3%. Hepatitis B vaccination protection was available to 100%.
CONCLUSIONS: The quality indicators recommended by the SGAIM for the transmission of provisional discharge reports, new prescriptions for benzodiazepines and transfusions with Hb values >8 g/dl proved helpful. Development potential was shown for the following quality indicators: CIRS case processing, biography of falls in the last 12 months and hepatitis B vaccination protection.

Abstract
Purpose
This study aimed to compare the outcomes of patients with ground-grass opacity (GGO)-dominant non-small cell lung cancer (NSCLC) who were treated with carbon ion radiotherapy (CIRT) versus segmentectomy.
Materials and methods
A retrospective review of medical records was conducted. The study included 123 cases of clinical stage 0/IA peripheral NSCLC treated with single-fraction CIRT from 2003 to 2012, 14 of which were determined to be GGO-dominant and were assigned to CIRT group. As a control, 48 consecutive patients who underwent segmentectomy for peripheral GGO-dominant clinical stage IA NSCLC were assigned to segmentectomy group.
Results
The patients in CIRT group, compared with segmentectomy group, were significantly older (75 ± 7.2 vs. 65 ± 8.2 years, P = 0.000660), more likely to be male (13/14 vs. 22/48, P = 0.00179), and had a lower forced vital capacity (91 ± 19% vs. 110 ± 13%, P = 0.0173). There was a significant difference in the 5-year overall survival rate (86% vs. 96%, P = 0.000860), but not in the 5-year disease-specific survival rate (93% vs. 98%, P = 0.368).
Discussion
Compared with segmentectomy, CIRT may be an alternative option for patients with early GGO-dominant NSCLC who are poor candidates for, or who refuse, surgery. (200 words)

Abstract
This paper presents new efficient six image interpolation techniques that aim to obtain high resolution images from low resolution ones. The problem of dealing with image interpolation as an inverse problem was treated in wavelet domain through the first proposed approach. This approach estimates wavelet coefficients in high frequency sub-images using least squares algorithm. The approach reveals performance improvement in PSNR and MSE values compared to bilinear and least squares algorithm. A second approach based on using artificial neural network for modeling the maximum entropy interpolation algorithm was presented. Training the suggested network is achieved by adjusting its weights using learning algorithm to minimize the sum of squared error between target and actual output of output neurons. The proposed approach requires fewer computations than the conventional high-quality image interpolation methods with little reduction in PSNR compared to the maximum entropy algorithm. A third algorithm which combines new contourlet transform and edge-based interpolation algorithm was proposed to improve object boundaries regularity which could be achieved by treating each successive approximation of the high-resolution image as a noisy approximation, hence enforcing the contourlet coefficients to have a sparsity constraint. The proposed algorithm gives an improvement of 2 dB in PSNR compared to IIGR algorithm and achieves the best MSE and correlation coefficient. The fourth approach presents an efficient method to get HR images from the fusion of Magnetic resonance and computed tomography images by adopting least-squares strategy to iteratively obtain wavelet sub-bands of the target HR image. The proposed approach was found to achieve good results especially when the curvelet transform is used to merge the CT and MR images. The fifth approach presents neural modeling of the maximum entropy image interpolation algorithm based on both curvelet and wavelet fusion. Through this approach the fusion process is performed while edges with a curved nature are preserved. Results showed that applying curvelet transform in the fusion of CT and MR images is better than DWT fusion and that interpolating the fused image by neural modeling of maximum entropy image interpolation algorithm is superior to interpolating the original MR and CT images. The sixth approach presents a new image scale-up, super-resolution, approach based on image fusion principle. MR and CT images were scaled-up using sparse-representation modeling with dictionary learning algorithms of Yang et. al. and Michael et. al.. The images were fused by discrete wavelet and curvelet transforms, then scaled-up by the same algorithms. Simulation results showed that scaling-up the fused MR and CT images, either by wavelet or curvelet fusion techniques, gives higher PSNR values than scaling-up the MR and CT image separately.
