Background: The underlying pathology of the vast majority of diabetic polyneuropathies is axonal degeneration. F wave study is one of the most sensitive indices of the severity of neuropathy. Objective: To test the validity of different F wave parameters including F minimum latency, F wave index and F Jitter in the diagnosis of diabetic axonal peripheral neuropathy. Methods: Eighty type 2 diabetics aged 52.57±5.62 years with disease duration of 1 to 18 years and 90 aged-matched healthy volunteers serve as the control group. Both groups were submitted to medical history, clinical neurological examination, and electrophysiological tests of both upper and lower limbs. Results: Tibial and ulnar F wave latencies were significantly prolonged in diabetic patients (p < 0.001). Tibial F index for male patients shows significantly lower value as compared to the control group. Ulnar F wave latency was 76.7% sensitive and 89.3% specific in female patients while tibial F wave latency was 80% sensitive and 81.3% specific in male patients. Conclusion: F wave is a precise parameter in detecting diabetic axonal peripheral neuropathy. Minimal F-wave latency is more sensitive than both F index and F Jitter in the diagnosis of axonal neuropathy in diabetic patients.

Background: Incisional hernia (IH) after abdominal surgery is a well-known complication and its incidence continues to be 10-15% after laparotomy. The repair of IH has always been a challenge to the surgeon. Various operative techniques for the repair of IH are in practice; however, the management is not standardized. The sublay technique has been reported to be quite effective, with low recurrence rates and minimal complications. Objective: To assess the advantage and complications of sublay mesh repair of IH in comparison to onlay mesh repair. Methods: Prospective study of 63 patients undergoing repair of IH from 1st January 2013 to 1st February 2015 done in General Surgical Unit of Al-Imamein Al-kadhmein Medical City. 42 cases of IH were managed by onlay mesh repair and 21 cases of IH were managed by sublay mesh repair. Results: Post-operative complications like seroma and wound infection were comparable in both groups. In sublay group seroma formation was one patient (4.76%). Wound infection was in one patient (4.76%). No septic mesh was removed in the series. In onlay group, seroma formation was in 9 patients (21.42%); most of seroma occur in large IH repair, wound infection was in 2 patients (4.76%) and one septic mesh was removed. In sublay recurrence rate was 0%, in onlay recurrence rate was in one patient (4.76%). Conclusion: Sublay mesh although it is more time consuming and technically more difficult, however, it carries low recurrence rate and few postoperative wound complication.

Published: February 2022

OBJECTIVE

To investigate the association of potential cardiovascular disease (CVD) biomarkers in patients with type 2 diabetes.

RESEARCH DESIGN AND METHODS:

We enrolled 120 participants (aged 61.5–69.5 years) with type 2 diabetes and 60 (aged 62.5–73.5 years) with normal glucose tolerance in the discovery group from the original Da Qing Diabetes Study. Their diabetes status was confirmed in 1986; then, the participants were followed over 23 years to collect CVD outcome data. Untargeted and targeted metabolomics analyses based on ultra-high-performance liquid chromatography–tandem mass spectrometry were used to identify potential markers. Multivariable regression analysis was used to evaluate the association between metabolites and CVD outcomes. An independent group of 335 patients (aged 67.0–77.0 years) with diabetes was used for biomarker validation.

RESULTS

In the discovery group, untargeted metabolomics analysis found 16 lipids and fatty acids metabolites associated with CVD risk in patients with diabetes, with palmitoyl sphingomyelin (PSM) having the strongest association. Plasma PSM concentrations were significantly higher in cases of diabetes with CVD than without (41.68 ± 10.47 vs. 9.69 ± 1.47 μg/mL; P < 0.0001). The odds ratio (OR) of CVD for 1 µg/mL PSM change was 1.19 (95% CI 1.13–1.25) after adjustment of clinical confounders. The validation study confirmed that PSM was significantly associated with increased CVD risk in diabetes (OR 1.22 [95% CI 1.16–1.30]).

CONCLUSIONS

Changes in lipid and fatty acid content were significantly associated with CVD risk in the Chinese population with diabetes. PSM is a potential biomarker of increased CVD risk in diabetes.

Published: February 2022

Objective: Epidemiological evidence
regarding the relationship between fructose intake and intrahepatic lipid
content (IHL) is inconclusive. We, therefore, assessed the relationship between
different sources of fructose and IHL at the population level.

Research Design and Methods: We used cross-sectional data from The
Maastricht Study, a population-based cohort (n=3,981;60±9years;50%women). We
assessed the relationship between fructose intake (assessed by a food frequency
questionnaire) – total and derived from fruit, fruit juice and sugar-sweetened beverages
(SSB) – and IHL (quantified by 3T-Dixon-MRI) with adjustment for age, sex, type
2 diabetes, education, smoking status, physical activity, and intakes of total
energy, alcohol, saturated fat, protein, vitamin E, and dietary fiber.

Results: Energy-adjusted total fructose
intake and energy-adjusted fructose from fruit was not associated with IHL in
the fully adjusted model (p=0.647 and p=0.767).

In contrast, energy-adjusted intake of
fructose from fruit juice and SSB was associated with higher IHL in the fully
adjusted models (p=0.019 and p=0.009). Individuals in the highest tertile of
energy-adjusted intake of fructose from fruit juice and SSB had a 1.04-fold
(95%CI: 0.99;1.11) and 1.09-fold (95%CI: 1.03;1.16) higher IHL, respectively,
when compared to the lowest tertile in the fully adjusted model. Finally, the
association for fructose from fruit juice was stronger in individuals with type
2 diabetes (p for interaction=0.071).

Conclusions: Fructose from fruit juice
and SSB is independently associated with higher IHL. These cross-sectional
findings contribute to current knowledge in support of measures to reduce the
intake of fructose-containing beverages as a means to prevent non-alcoholic
fatty liver disease at the population level.

Authors: Al-Akhmmadi Saer , Shuldan Larysa
Published: February 2022

The problem of photovoltaics integration into the building of architectural heritage is in the zone of compromise between aspects of preservation and long-term use. The quality and success of such energy modernization are based on the principles of preserving and extending the term of the utilitarian use of buildings. It is crucial in this situation to determine the key principles of solar cell integration into buildings that form the historic environment. The constituent values of historic buildings form the basis for their definition. Domestic researchers have previously focused on some issues of "inconsistency" in the domestic monument protection legislation, which occur not only without formal violations of the law but on the contrary, based on its rules. The article continues the research of problems, methods, rules, and limitations of photovoltaic systems integration into the architecture of historical buildings initiated by the authors. The purpose of this article is to consider issues related to the cultural value preservation of the historic buildings in the integration of solar systems, as well as to determine the priorities, value characteristics defined by legislative and regulatory documents of Ukraine, value components of the historic buildings. The purpose is also to measure the value components` interaction and to form the principles of solar cell integration based on it. The basic priority in making decisions on energy modernization, switching to new energy types, and introducing solar generation, is to promote the preservation and long-term operation of cultural heritage buildings. In total, the components form a broader definition of the value of historic buildings and environment, which goes beyond what is defined by law. Decisions on energy measures for cultural heritage buildings require a search for a balance of priorities between different value components. Based on the value components, nine principles of solar cells integration into historic buildings have been formed.

Published: February 2022

Paving block (concrete brick) is a composition of building materials made from a mixture of Portland cement or other hydraulic adhesive. The making of paving blocks is done by a process of molding, soaking, physical testing including compressive strength, density, porosity, and absorption, and characterization including XRF and XRD. The paving blocks are made without the addition of basalt stone and rice husk ash and with the addition of 5%, 10%, 15%, 20% and 25% with a test life of 7 days, 14 days and 28 days. The materials used are cement, sand, basalt stone, rice husk ash and water. Paving blocks without the addition of basalt stone and rice husk ash have the highest compressive strength at the test age of 28 days of 9.9 MPa and absorption of 15.06%, whereas with the addition of basalt stone and rice husk ash the highest compressive strength is at a concentration of 5% at age 28day test of 12.25 MPa and the absorption value of 7.12%. The results of XRF characterization showed that the more concentrations of basalt stone and rice husk ash, the CaO contained in the paving blocks increased while the SiO2 decreased. The results of XRD characterization showed that the phases formed were ternesite, microline maximum and yeelimite.

Published: February 2022

The well-known anti-doping investigations of the last decade led to the disqualification from participation in the Olympics not only of individual athletes who were convicted of taking illegal drugs, but entire sports federations, the national anti-doping agencies were deprived of their accreditation. Bringing to justice a wide range of individuals not directly related to the use of doping requires a new approach to evidence as such and to the way it is presented. The purpose of this study is to study the status and procedural situation of WADA whistleblowers – the persons on whose testimony most of the investigations were based. The authors analyze the distinctive procedural features of informants and a set of requirements for information provided by informants. The article discusses the issue of mixing the statuses of a witness and an accomplice in the formation of approaches to determining the informant, with the legal consequences arising from these statuses. The authors note that WADA, as an international organization, does not have the functionality to ensure the protection of a whistle-blower from domestic persecution, for this reason, national law enforcement agencies play the main role in protecting whistleblowers. The extent and form of protection also depends on the status of anti-doping investigations and the assessment of doping as an offense punishable by criminal proceedings, civil or administrative.

Rheological Characterization and EHL Simulation of a Grease in a Lubricated Sealing Contact
Authors: Bauer Niklas , Hahn Susanne , Feldmeth Simon , Bauer Frank , Schmitz Katharina
Published: February 2022

This contribution provides an insight into the tribological behavior of grease-lubricated contacts in pneumatic spool valves. As the properties of the grease are strongly non-Newtonian, multiple measurements were performed to parameterize two viscosity models, the Herschel-Bulkley and the Palacios-Palacios model. These models are integrated into an EHL simulation of the sealing contact and qualitatively compared for two temperatures. For that system, the total friction force is rather unaffected by the choice of the viscosity model. In addition, qualitatively similar results with about 10 % deviation from the non-Newtonian behavior could be obtained using a Newtonian approximation of the lubricant.

Design of a Fuzzy Fractional Order Adaptive Impedance Controller with Integer Order Approximation for Stable Robotic Contact Force Tracking in Uncertain Environment
Authors: Cao Hongli
Published: February 2022

Current research in robot compliance control is unable to take both transient contact force overshoots and steady-state force tracking problems into account. To address this problem, we propose a fuzzy fractional order (FO) adaptive impedance controller to avoid the force overshoots in the contact stage while keeping force error in the dynamic tracking stage, where traditional control algorithms are not competent. A percentage gain is adopted to map FO parameters to integer order (IO) parameters by their natural properties, and a fuzzy logical controller is introduced to improve the system stability. The simulation results indicate that the proposed controller can be made more stable than and superior to the general impedance controller, and the force tracking results also have been compared with the previous control methods.

Published: February 2022

In this paper, a numerical study of forced convection on a backward facing step containing a single-finned fixed cylinder has been performed, using a ferrofluid and external magnetic field with different inclinations. The partial differential equations, which determine the conservation equations for mass, momentum and energy, were solved using the finite element scheme based on Galerkin’s method. The analysis of heat transfer characteristics by forced convection was made by taking different values of the Reynolds number (Re between 10 and 100), Hartmann number (Ha between 0 and 100), nanoparticles concentration (φ between 0 and 0.1) and magnetic field inclination (γ between 0° and 90°); also, several fin positions α [0°–180°] were taken in the counter clockwise direction by a step of 5. After analysing the results, we concluded that Hartmann number, nanoparticles concentration, Reynolds number and magnetic field angles have an influence on the heat transfer rate. However, the fin position on the cylinder has a big impact on the Nusselt number and therefore on heat transfer quality. The best position of the fin is at (α = 150°), which gives the best Nusselt number and therefore the best heat transfer, but the fin position at (α = 0°) remains an unfavourable case that gives the lowest Nusselt values.
Modelling of Iron Ore Processing in Technological Units Based on the Hybrid Approach
Authors: Morkun Vladimir , Tron Vitalii , Zymohliad Vadym
Published: February 2022

The process line of concentrating iron ore materials is considered as a sequence of connected concentration units, some of which partially return ore materials to the previous unit. The output product of the final concentration unit in the process line is the end product of the whole line. Characteristics of ore, such as distribution of ore particles by size and distribution of iron content by size classes, are considered. Processing of iron ore materials by process units (a cycle, a scheme) is characterised by a separation characteristic – namely the function of extracting elementary fractions depending on physical properties of ore particles. The results of fraction analysis of ore samples in different points of the process line provide an experimental definition of separation characteristics and numerical values of the Rosin–Rammler equation factors. To identify dependencies that cannot be analytically described, the hybrid approach accompanied by the Takagi–Sugeno fuzzy models, in accompaniment with triangular membership functions determining fuzzy sets in preconditions, are used. To identify fuzzy sets in rule preconditions, triangular membership functions are used. Introduction of a-priori data on iron ore concentration as constraints for model parameters is a promising trend of further research, since it enables increased accuracy of identification despite limited availability of experimental data.

Published: February 2022

The analysis and structural transformation of power-related picture elements is an essential result of regional power grid research. This paper proposes a new idea for extracting monolithic insulator images based on analysing the characteristics of scanned colour grid power insulators. At the same time, the article extracts the RGB colour matrix of the insulator based on the BP neural network algorithm. Then, it uses it as a characteristic parameter for training and analysis. Combining the characteristics of image data, it is found that the model proposed in this paper enhances the ability to express images, thereby improving the accuracy of image classification. Furthermore, many experiments on the accurate data set of insulator monoliths show the effectiveness of this model.
