In vitro modeling of the loading of a hip joint endoprosthesis from с/с composite with damaged areas
Authors:   Perm National Research Polytechnic University, Razumovskii Egor , Shavshukov Vyacheslav
Published: August 2024

The influence of the biological process of osteointegration on the change of elastic modules of the material of the leg of the hip joint (c/c composite) in areas with damage to pyrocarbon crystallites has been studied. Damage occurs as a result of extreme loads performed by a person, which leads to a decrease in the bearing capacity of the endoprosthesis leg. As a result of damage, the pyrocarbon matrix becomes similar to a loose granular medium, which significantly reduces the elastic properties of the material as a whole. A positive change in the elastic modules of the endoprosthesis leg material during osseointegration can lead to blocking the spread of damaged areas and an increase in the bearing capacity of the endoprosthesis. The prediction of elastic modules in the damaged areas of the endoprosthesis is performed in two stages. At the first stage, the elastic properties of the new matrix in the damaged areas are calculated, which is a combination of osteoblasts and a pyrocarbon matrix of a c/c composite. At the next stage, the effective properties of a unidirectional c/c composite with a modified matrix are calculated. When predicting elastic modules, the direct homogenization method implemented in the Ansys Material Designer module is used. The prediction of the effective properties of a three-dimensional reinforced c/c composite, in the pores of which osteoblasts are embedded, is performed according to the Tarnopolsky model. When modeling loading, spatial models of human bones are used, obtained using computed tomography and converted into solid-state models. The magnitude of the load on the biomechanical system is determined by the bearing capacity of the endoprosthesis leg in case of damage in four areas without taking into account the introduction of osteoblasts. The study presents the results of calculations of stress and strain fields for the hip joint endoprosthesis structure and presents a diagram of the deformation of the endoprosthesis leg in load-displacement coordinates, showing the altered bearing capacity of the endoprosthesis. The numerical results clearly demonstrate the influence of the biological process of osteointegration on the change in the bearing capacity of the endoprosthesis and elastic properties in the damaged areas of the material.
Relation of the oxygen saturation and blood flow in different structural parts of the microvascular system of the human skin
Authors:   Tulа State Pedagogical University named after L.N. Tolstoy, Krasnikov Gennadij , Mizeva Irina ,   Institute of Continuous Media Mechanics UrB RAS
Published: August 2024

The most important function of the human cardiorespiratory system is the supply tissues by oxygen and the microvascular system plays a key role in this process. To date, the physiologically important relationship between tissue oxygen saturation and blood flow remains insufficiently studied. The aim of this study is to estimate the relationship between blood flow fluctuations in the microvessels and tissue oxygen saturation in skin as a function of blood flow velocity and microvessel type under native conditions and during local heating. This work utilizes measurements published in an open database obtained with the EPOS method, which combines a probe for measuring tissue perfusion differentiated by microvessel type, a sensor for determining tissue oxygenation, and a heater. The data collected during the test with local heating up to 40°C were selected from the database. It was obtained that unlike perfusion spectra, tissue oxygenation spectra are concentrated in the low-frequency region. The peculiarities of the relationship between the oxygen saturation level and blood flow fluctuations in human skin microvessels depending on their type have been demonstrated. The oxygenation signal is modulated by blood flow in a wide range of frequencies, with low-frequency modulations corresponding to endothelium-dependent, neurogenic, and myogenic oscillations having a stronger relationship between SO2 level and perfusion fluctuations. Such oscillations are functionally significant, related to oxygen extraction processes. Higher correlation of low-frequency SO2 fluctuations and blood flow fluctuations is typical for perfusion components associated with capillary blood flow and small arterioles.
Hemodynamics of the superficial femoral artery: clinical case study
Authors:   Meshalkin National Medical Research Cente, Kuianova Iuliya , Gostev Aleksandr , Parshin Daniil
Published: August 2024

The superficial femoral artery, in contrast to the deep femoral artery, is most often affected by atherosclerosis with the formation of hemodynamically significant stenoses or occlusions, which leads to ischemia of the lower limb. The latest Russian and European guidelines for peripheral arterial disease currently recommend an endovascular strategy (angioplasty and stenting) for all lesions shorter than 25 cm. The study of the hemodynamics of the superficial femoral artery is complicated by the fact that it is subject to severe deformation (compression, stretching, torsion) during physiological movements in the hip and knee joints. In this regard, a very urgent task is the numerical modeling of hemodynamics before and after angioplasty and stenting of the affected artery to assess the redistribution of blood flow in the great vessels of the lower limb. The work performed a numerical study of the hemodynamics of the arteries of the lower extremities under normal conditions, with occlusion, and with installed virtual stents of various porosities for a specific patient. It has been established that, depending on the chosen stent, the volume of blood flow through the superficial femoral artery can vary up to 15 %, and in general, the redistribution of blood flow can reach up to 50 % compared to a healthy limb. For stents with a porosity index of 0.1–0.2, the shear stresses in the stent area are up to 5 times higher than for stents for which this value is 0.8, although the maximum WSS over the entire configuration remains comparable, which indicates possible significantly different stent endothelialization scenarios. A deeper understanding of these processes will make it possible to determine the choice of treatment tactics and the type of implanted device, which can ultimately improve the immediate and long-term results of surgical treatment, as well as improve the patient’s rehabilitation status.
Comparative study of the viscoelastic behaviour of hernia meshes
Authors:   Institute of Mechanics, Pashkouleva Dessislava , Kirilova-Doneva Miglena ,   Faculty of Pharmacy, Medical University of Sofia
Published: August 2024

The time-dependent mechanical behaviour of hernia meshes may have an influence on the quality of hernia repairs. Viscoelastic behaviour of commonly used meshes in surgical practice in Bulgaria was investigated. The nine meshes (standard and light-weight meshes), differing from each other with respect to composition and weight, were put to the ex vivo relaxation tests at applied nominal strains of 5 %. The stress relaxation phenomena were monitored for 1800 s. The experimental results clearly demonstrate the orthotropy of the all hernia meshes. The changes in the stress reduction were 19–100 % after half an hour. Mean value of the reduction of the stress during relaxation ΔT for standard meshes is 66.84 ± 23.98 %, while ΔT for lightweight meshes is 51.48 ± 34.55 %. There are four meshes for which the tension falls to 0 MPa. All parameters of lightweight meshes change in broader intervals than those of standard meshes and have higher values. For lightweight meshes stress reduction decreases when density increases, while for standard meshes an opposite trend was observed. The parameters of polypro-pylene meshes change in broader intervals than the parameter of composite and poly-ethylene terephthalate meshes. Our results about the level of stress reduction can be used as a reference for improvement of hernia meshes.

In the study, both uncomplexed and calcium-containing complex liposomes made of DPPA and DPPC phospholipids were studied calorimetrically and spectrophotometrical-ly. Liposomes with a diameter of 200 nm were produced by new nanotechnology. As cal-cium molecules, CaCO3 was used, which is used in medicine as a calcium supplement or antacid, which is used to relieve heartburn, stomach acidity. Complex liposomes were prepared in both water and 20 % glycerol solvent. As calorimetric and spectrophotometric experiments show, CaCO3 molecules made by new technology are incorporated into the structure of liposomes, which allows them to be used for treatment. In addition, calcium is placed in large quantities in such complex liposomes, although their entry into the blood does not cause side effects. The structure and thermal stability of complex liposomes were deter-mined in the paper. In particular, according to the obtained experimental results, we believe that the struc-ture of calcium-containing nanoparticles can be both unilaminar and multilaminar, in par-ticular, the structure of uncomplexed and calcium-containing DPPC liposomes prepared in water and glycerol are multilaminar. The structure of uncomplexed DPPA liposomes prepared in water is unilaminar, while calcium-containing DPPA liposomes prepared in water form a multilayer structure. As for the structure of both pure and calcium-containing DPPA liposomes prepared in glycerolare multilamellar. With some preliminary considera-tions, calcium-containing liposomes can be tested in experimental animals, and after obtaining positive results, they can be recommended for the treatment of hypocalcemia in humans.

A client will have the capacity to decode if and just if his properties fulfill the figure content's arrangement. In this work, we show the primary development of a cipher text-approach characteristic based encryption plan having security evidence in view of a number theoretic presumption and supporting propelled access structures. Past CP-ABE frameworks could either bolster just exceptionally constrained access structures or had a proof of security just in the non specific gathering model. Our development can bolster access structures which can be spoken to by a limited size access tree with edge doors as its hubs. The bound on the extent of the entrance trees is picked at the season of the framework setup. Our security evidence depends on the standard Decisional Bilinear Daffier Hellman suspicion.

consumption in Very Large Scale Integration (VLSI) circuits. By leveraging historical design data, we develop and
validate predictive models that aid designers in making power-efficient decisions early in the design process. Our
results show significant improvements in prediction accuracy, highlighting promising directions for future VLSI design
optimization.
Cost-oriented fire safety design of urban structures
Authors: Irãni Mátin , Behnam Behrouz
Published: August 2024

Providing adequate fire safety for urban buildings is a life-saving goal, and can be addressed in different ways. Reported studies integrating fire safety and life cycle cost (LCC) of conventional urban structures are rare. To address this gap, a cost–performance framework was developed. Four- and seven-storey steel (with and without fireproofing coatings) and reinforced concrete (RC) structures were designed, first for conventional loads and then fireproofed to meet their required fire-resistance rating. A range of sprinkler spacings, from 3200 mm (based on NFPA 13) to 12 000 mm, was configured. Fire was simulated using a fire dynamic simulation tool and the results were used to monitor evacuation plans and structural responses. The steel structures were additionally analysed under the assumption that they were not fireproofed. Human and financial damage costs were then estimated and the LCC for every case/scenario was determined. Interestingly, the results showed that the optimum LCC was not achieved for cases designed based on NFPA 13; instead, a sprinkler spacing of 6000 mm led to the optimum LCC. It was also found that steel structures without fireproofing do not have a higher LCC if the sprinklers are placed over a shorter distance. This result could be particularly beneficial for existing structures that are not fireproofed.
Reviewing the use of monitoring tools for rural water pumps in the Global South
Authors: Clerkin Martin , Swan Andrew
Published: August 2024

The establishment of improved water supplies is one of the United Nation’s Sustainable Development Goals. Many water schemes have provided wells and pumps to enhance the life of local communities across Africa. However, in numerous cases, these schemes fail over time due to a lack of established maintenance regimes and trained staff. One of the ways that resilience might be improved is the introduction of remote monitoring systems to allow the detection of failed pumps and enable predictions of when a pump might fail without intervention, thus allowing the associated loss of service to be minimised, ensuring that the community is not without safe drinking water for extended periods. This paper pulls together the knowledge and details of remote monitoring systems that are available in the field today and provides a coherent knowledge base of the work that is being done. The paper also reviews how each system is compiled, along with their strengths and weaknesses, and provides background knowledge that should encourage future research and development in the field. Whether such systems, with their reliance on microprocessors, are appropriate for the Global South is discussed.
Justiciability of economic, social and cultural rights under the legal system of South Sudan: A preliminary assessment
Authors: Valfredo Ruben SP
Published: August 2024

This article provides an overall assessment on the justiciability of economic, social and cultural rights (ESCRs) within the legal system of South Sudan. It establishes that, in theory, ESCRs are justiciable under the legal system of South Sudan in a complementary and collaborative manner at two levels, namely, the national and supranational. The article argues that ESCRs may in theory be legally and judicially enforceable by virtue of the Constitution and domestic legislation. Furthermore, ESCRs are justiciable by virtue of the automatic incorporation of numerous treaties into the Bill of Rights in the Constitution, with these treaties also effecting justiciability as part of the international treaty obligations of South Sudan. It further asserts that there are two parallel layers, national and supranational, which give effect to the legal realisation of ESCRs in South Sudan. This is presented through numerous domestic constitutional and legal provisions, and also international and regional treaty obligations of South Sudan. For that purpose, the article appraises relevant provisions in the Constitution, domestic laws, and United Nations and regional treaties to which South Sudan is a state party. In addition, the article examines a number of bodies and entities that are established by these frameworks to operationalise the enforcement of ESCRs. The article concludes that this composite situation forms a basis for all the instruments and structures to supplement and complement one another in a non-hierarchical perspective. The view expressed in the article is that the current status remains theoretical and is empirically and practically challenged by the factual realities that hinder and hamper the operationalisation of justiciability in South Sudan. It recommends that a practical test is required in order for a comprehensive legal jurisprudence about the justiciability of ESCRs in and for South Sudan to materialise.

Riesgo climático en los servicios de Salud Local en Ecuador
Authors: Vilema-Escudero Segundo , Manya Orellana Marlon
Published: August 2024

This work analyzes the interaction between climate risk, caused by extreme events resulting from the El Niño-Southern Oscillation (ENSO) phenomenon and/or Climate Change, and its impact on local health services in Ecuador. The analysis focuses on Ecuador’s growing vulnerability to the effects of climate change, which exacerbates challenges in the delivery of health services, particularly in the context of severe climate events. The main objective is to analyze the relationship between the number of hectares affected by climate events and the availability and effectiveness of local health services, considering community resilience and health coverage as moderating variables. The methodology uses a linear regression analysis using data from 221 Ecuadorian municipalities, covering variables such as climate risk, health services, community resilience, health coverage, and demographic and socioeconomic factors. The results indicate a significant influence of climate risk on the effectiveness of health services, moderated by community resilience and health coverage. It is observed that areas with greater preparation and health coverage show a better capacity to respond to extreme weather events. Finally, it is important to integrate climate risk management into health services planning, suggesting that greater community resilience and broad health coverage are essential to mitigate the negative impacts of climate change on public health.

Guinea pigs in intensive production generates an imperative necessity of physio-pathological bases for diagnosing their state of welfare, health, and production; those which are available for this species are referred to as laboratory or companion animal. The aim of this research is to determine changes in hematological and blood metabolites profiles in relation to age of Cavia porcellus reared in intensive system at 660 masl in humid tropic. For this purpose, forty 15-120 days old guinea pig in healthy conditions from the inti x Peru lines born in the humid tropic were used and the evaluation ages were 15-21, 22-35, 36-60 and 61-120 days. Blood samples were obtained by puncture of the cephalic vein; profiles of erythrocytes (RBC), total leucocytes (WBC), lymphocytes, granulocytes, hematocrit, hemoglobin, MCV, MCH and MCHC indices were determined. In serum, profiles of glucose, total protein (TP), albumin, total cholesterol (TC), triglycerides, total bilirubin (TB), and direct bilirubin (DB), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were determined. Hemoglobin profile, MCH and MCHC indices increased as age increased (p < 0,05) and the erythrocytes, leucocytes, hematocrit, hemoglobin profiles and MCV, MCH, MCHC indices showed the narrower interval ranges in the 15-35and 61-120-days old guinea pigs. Profiles of TP, DB and AST showed increase with age (p < 0,05) and the DB, AST, ALT, and TC profiles showed the narrower interval range at 36-120 days old. The hematological and blood metabolites profiles of guinea pigs raised in intensive system in humid tropical conditions show significant changes with production age.
