Clones in Blackface and Drag: The Promise and Privilege of the Feminist Biotechnological Imaginary
Authors: Hines Megan
Published: February 2022

This article discusses the visual culture of the feminist biotechnological imaginary, a technofeminist belief that a feminist society could be technologically engineered at the biological level. In the United States, many second-wave feminists embraced the possibility that reproductive technologies might facilitate women’s liberation from biological determinism. The idea that biology could become a tool for self-fashioning and diverse community building rather than a fixed determining force resulted in gender and race becoming mutable categories. Both race and gender became subject to technological intervention as well as technologies in themselves. Within the visual culture of the feminist biotechnological imaginary, images of clones served to examine the tension between unity and diversity in the feminist movement. Working in this context, the white women-identified artists Lynn Hershman Leeson, Cindy Sherman, and Eleanor Antin constructed representations of themselves in drag and blackface. I argue that these representations related to the visual culture of feminist clones and undermined gendered power structures while ultimately reinforcing existing racial ones.
Surrogate Humanity: Resistant Art Practices under Technoliberalism
Authors: Kang Stephanie
Published: February 2022

This essay reviews the book Surrogate Humanity: Race, Robots, and the Politics of Technological Futures, co-written by Neda Atanasoski and Kalindi Vora. In this critical text, Atanasoski and Vora consider the ways in which liberal structures of anti-Blackness, settler colonialism, and capitalist exploitation have been ingrained into robotic technologies. By revealing the interwoven relationship between technological development and racial dispossession, Surrogate Humanity searches for alternative models of human-machine interactions that can destabilize social inequalities and their reproductions.

Published: February 2022

Background

Rapid advances in technologies over the past 10 years have enabled large-scale biomedical and psychosocial rehabilitation research to improve the function and social integration of persons with physical impairments across the lifespan. The Biomedical Research and Informatics Living Laboratory for Innovative Advances of New Technologies (BRILLIANT) in community mobility rehabilitation aims to generate evidence-based research to improve rehabilitation for individuals with acquired brain injury (ABI).

Objective

This study aims to (1) identify the factors limiting or enhancing mobility in real-world community environments (public spaces, including the mall, home, and outdoors) and understand their complex interplay in individuals of all ages with ABI and (2) customize community environment mobility training by identifying, on a continuous basis, the specific rehabilitation strategies and interventions that patient subgroups benefit from most. Here, we present the research and technology plan for the BRILLIANT initiative.

Methods

A cohort of individuals, adults and children, with ABI (N=1500) will be recruited. Patients will be recruited from the acute care and rehabilitation partner centers within 4 health regions (living labs) and followed throughout the continuum of rehabilitation. Participants will also be recruited from the community. Biomedical, clinician-reported, patient-reported, and brain imaging data will be collected. Theme 1 will implement and evaluate the feasibility of collecting data across BRILLIANT living labs and conduct predictive analyses and artificial intelligence (AI) to identify mobility subgroups. Theme 2 will implement, evaluate, and identify community mobility interventions that optimize outcomes for mobility subgroups of patients with ABI.

Results

The biomedical infrastructure and equipment have been established across the living labs, and development of the clinician- and patient-reported outcome digital solutions is underway. Recruitment is expected to begin in May 2022.

Conclusions

The program will develop and deploy a comprehensive clinical and community-based mobility-monitoring system to evaluate the factors that result in poor mobility, and develop personalized mobility interventions that are optimized for specific patient subgroups. Technology solutions will be designed to support clinicians and patients to deliver cost-effective care and the right intervention to the right person at the right time to optimize long-term functional potential and meaningful participation in the community.

An Android-Based Mobile App (ARVPredictor) for the Detection of HIV Drug-Resistance Mutations and Treatment at the Point of Care: Development Study
Authors: Ongadi Beatrice , Lihana Raphael , Kiiru John , Ngayo Musa , Obiero George
Published: February 2022

Background

HIV/AIDS remains one of the major global human health challenges, especially in resource-limited environments. By 2017, over 77.3 million people were infected with the disease, and approximately 35.4 million individuals had already died from AIDS-related illnesses. Approximately 21.7 million people were accessing ART with significant clinical outcomes. However, numerous challenges are experienced in the delivery and accurate interpretation of data on patients with HIV data by various health care providers at different care levels. Mobile health (mHealth) technology is progressively making inroads into the health sector as well as medical research. Different mobile devices have become common in health care settings, leading to rapid growth in the development of downloadable software specifically designed to fulfill particular health-related purposes.

Objective

We developed a mobile-based app called ARVPredictor and demonstrated that it can accurately define HIV-1 drug-resistance mutations in the HIV pol gene for use at the point of care.

Methods

ARVPredictor was designed using Android Studio with Java as the programming language and is compatible with both Android and iOS. The app system is hosted on Nginx Server, and network calls are built on PHP’s Laravel framework handled by the Retrofit Library. The DigitalOcean offers a high-performance and stable cloud computing platform for ARVPredictor. This mobile app is enlisted in the Google Play Store as an “ARVPredictor” and the source code is available under MIT permissive license at a GitHub repository. To test for agreement between the ARVPredictor and Stanford HIV Database in detecting HIV subtype and NNRT and NRTI mutations, a total of 100 known HIV sequences were evaluated.

Results

The mobile-based app (ARVPredictor) takes in a set of sequences or known mutations (protease, reverse transcriptase and integrase). It then returns inferred levels of resistance to selected nucleoside, nonnucleoside protease, and integrase inhibitors for accurate HIV/AIDS management at the point of care. The ARVPredictor identified similar HIV subtypes in 98/100 sequences compared with the Stanford HIV Database (κ=0.98, indicating near perfect agreement). There were 89/100 major NNRTI and NRTI mutations identified by ARVPredictor, similar to the Stanford HIV Database (κ=0.89, indicating near perfect agreement). Eight mutations classified as major by the Stanford HIV Database were classified as others by ARVPredictor.

Conclusions

The ARVPredictor largely agrees with the Stanford HIV Database in identifying both major and minor proteases, reverse transcriptase, and integrase mutations. The app can be conveniently used robustly at the point of care by HIV/AIDS care providers to improve the management of HIV infection.
A New Performance Metric to Estimate the Risk of Exposure to Infection in a Health Care Setting: Descriptive Study
Authors: Hadian Kimia , Fernie Geoff , Roshan Fekr Atena
Published: February 2022

Background

Despite several measures to monitor and improve hand hygiene (HH) in health care settings, health care-acquired infections (HAIs) remain prevalent. The measures used to calculate HH performance are not able to fully benefit from the high-resolution data collected using electronic monitoring systems.

Objective

This study proposes a novel parameter for quantifying the HAI exposure risk of individual patients by considering temporal and spatial features of health care workers’ HH adherence.

Methods

Patient exposure risk is calculated as a function of the number of consecutive missed HH opportunities, the number of unique rooms visited by the health care professional, and the time duration that the health care professional spends inside and outside the patient’s room without performing HH. The patient exposure risk is compared to the entrance compliance rate (ECR) defined as the ratio of the number of HH actions performed at a room entrance to the total number of entrances into the room. The compliance rate is conventionally used to measure HH performance. The ECR and the patient exposure risk are analyzed using the data collected from an inpatient nursing unit for 12 weeks.

Results

The analysis of data collected from 59 nurses and more than 25,600 records at a musculoskeletal rehabilitation unit at the Toronto Rehabilitation Institute, KITE, showed that there is no strong linear relation between the ECR and patient exposure risk (r=0.7, P<.001). Since the ECR is calculated based on the number of missed HH actions upon room entrance, this parameter is already included in the patient exposure risk. Therefore, there might be scenarios that these 2 parameters are correlated; however, in several cases, the ECR contrasted with the reported patient exposure risk. Generally, the patients in rooms with a significantly high ECR can be potentially exposed to a considerable risk of infection. By contrast, small ECRs do not necessarily result in a high patient exposure risk. The results clearly explained the important role of the factors incorporated in patient exposure risk for quantifying the risk of infection for the patients.

Conclusions

Patient exposure risk might provide a more reliable estimation of the risk of developing HAIs compared to ECR by considering both the temporal and spatial aspects of HH records.

Published: February 2022

Background

Gay, bisexual, and other men who have sex with men (GBMSM) face the highest burden of HIV in the United States, and there is a paucity of efficacious mobile health (mHealth) HIV prevention and care interventions tailored specifically for GBMSM. We tested a mobile app combining prevention messages and access to core prevention services for GBMSM.

Objective

This study aims to measure the efficacy of the Mobile Messaging for Men (M-cubed) app and related services to increase HIV prevention and care behaviors in diverse US GBMSM.

Methods

We conducted a randomized open-label study with a waitlist control group among GBMSM in 3 groups (low-risk HIV-negative group, high-risk HIV-negative group, and living-with-HIV [LWH] group) recruited online and in venues in Atlanta, Detroit, and New York City. Participants were randomly assigned to receive access to the app immediately or at 9 months after randomization. The app provided prevention messages in 6 domains of sexual health and offered ordering of at-home HIV and sexually transmitted infection test kits, receiving preexposure prophylaxis (PrEP) evaluations and navigation, and service locators. Serostatus- and risk-specific prevention outcomes were evaluated at baseline, at the end of the intervention period, and at 3, 6, and 9 months after the intervention period.

Results

In total, 1226 GBMSM were enrolled and randomized; of these 611 (49.84%) were assigned to the intervention group and 608 (99.51%) were analyzed, while 615 (50.16%) were assigned to the control group and 612 (99.51%) were analyzed. For high-risk GBMSM, allocation to the intervention arm was associated with higher odds of HIV testing during the intervention period (adjusted odds ratio [aOR] 2.02, 95% CI 1.11-3.66) and with higher odds of using PrEP in the 3 months after the intervention period (aOR 2.41, 95% CI 1.00-5.76, P<.05). No changes in HIV prevention or care were associated with allocation to the intervention arm for the low-risk HIV-negative and LWH groups.

Conclusions

Access to the M-cubed app was associated with increased HIV testing and PrEP use among high-risk HIV-negative GBMSM in 3 US cities. The app could be made available through funded HIV prevention providers; additional efforts are needed to understand optimal strategies to implement the app outside of the research setting.

Vitamin D levels in children with celiac disease
Authors: Sorokman T.V. , Popelyuk N.O. , Koliesnik D.I. , Sokolnyk І.S.
Published: February 2022

Background. A significant increase in understanding of the role of vitamin D in the body, more effective detection of celiac disease, and the need to monitor the health of children against the background of long-term adherence to a gluten-free diet were prerequisites for our study. The study was aimed to analyze the level of vitamin D in children with celiac disease. Materials and methods. The results of the examination of 29 children aged from 6 months to 18 years with a verified diagnosis of celiac disease were analyzed. Serum vitamin D levels were measured by the electrochemiluminescent method (Roche Diagnostics GmBH, Mannheim, Germany). The results of vitamin D supplementation in patients with celiac disease were compared with the control group of 30 healthy children aged from 1 to 18. Mathematical processing of the material included a standard algorithm for statistical research using Microsoft Excel 2016, Attestat. Results. Among the patients included in the study, typical celiac disease was found in 24 (82.7 %) cases, which is 4.8 times more common than atypical — in 5 (17.4 %) children. The gastrointestinal symptoms dominated in a clinical picture. Manifestation of the disease in most patients was observed in the first year of life — in 17 (58.6 %) cases, in 7 (24.1 %) patients aged from 1 to 3 years, and only in 5 (17.4 %) children older than 3 years. The average rate of vitamin D in children with celiac disease was probably lower than in healthy children and accounted for 24.4 ± 1.2; 21.2 [16.45–35.21] ng/ml. The number of children with normal vitamin D content is the highest among young patients, while the frequency of vitamin D deficiency is the lowest. The median serum vitamin D in patients on a gluten-free diet was 1.4 times higher (p < 0.05) than in the acute period, but 1.3 times lower (p < 0.05) than in the control group. Adherence to a gluten-free diet leads to increased levels of vitamin D but does not allow reaching the level in healthy children. Conclusions. Vitamin D deficiency is registered in children with celiac disease. All patients with celiac disease, regardless of the stage of the disease and adherence to a gluten-free diet, need to be monitored for vitamin D levels.
Mechanisms of action of intranuclear microRNAs. Part 1. Influence of microRNA on transcription
Authors: Abaturov A.E. , Babуch V.L.
Published: February 2022

The scientific review presents the mechanisms of action of intranuclear miRNAs, namely the influence of intranuclear miRNAs on transcription. To write the article, information was searched using Scopus, Web of Science, MedLine, PubMed, Google Scholar, EMBASE, Global Health, The Cochrane Library, CyberLeninka databases. The authors cite differences between nuclear and cytoplasmic functions of miRNAs. It is emphasized that the regulation of miRNA transcription is carried out mainly due to the formation of heterochromatin, and the control of translation is performed by various mechanisms. The result of microRNA action in most cases is a decrease in gene expression. However, in some cases, miRNAs can enhance gene expression activity. Intranuclear miRNAs are able to induce pretranslational silencing of protein-encoding genes, activate transcription, alter ncRNA trans­criptome, and participate in the regulation of alternative splicing. It is shown that microRNA-mediated transcriptional silencing is induced by small RNAs in the cell nucleus, which promote DNA methylation and together with Argonaute proteins are involved in chromatin modification. In microRNA-mediated transcriptional silencing, DNA methyltransferases are recruited, RNA-induced transcriptional silencing complex is formed, microRNA interacts with promoter-associated nсRNAs and DNA of target genes, and heterochromatin is formed. The authors state that the formation of heterochromatin occurs in several stages: the initiation of assembly, assembly and distribution of heterochromatin. Thus, miRNAs can act as regulators of various processes and differences between the functions and effects of miRNAs depend on their location in the nucleus or cytoplasm of the cell. MicroRNAs in the cell nucleus control transcription, in the cytoplasm — translation. The mechanism of action of intranuclear miRNAs includes induction of pretranslational silencing of protein-encoding genes, activation of transcription, alteration of ncRNA transcriptomes, participation in the regulation of alternative splicing.
Синдром Персонейджа — Тернера: принципи діагностики й лікування
Authors: Delva I.I.
Published: February 2022

Синдром Персонейджа — Тернера (СПТ) — гостра нетравматична мультифокальна патологія плечового сплетення і його гілок неуточненої етіології. Як етіологічні розглядаються інфекційні, імунні, механічні й спадкові фактори. СПТ характеризується монофазним перебігом з гострим початком, варіабельним за часом періодом плато, повільним відновленням, різноманітними резидуальними явищами у вигляді хронічного болю й парезів. Захворювання маніфестує виникненням раптового гострого болю в плечовому поясі й руці. Протягом першого тижня захворювання на стороні болю приєднуються рухові розлади, які в 70 % випадків виникають у м’язах, що іннервуються верхнім стовбуром плечового сплетення. При підозрі на СПТ мають бути виключені: травми, компресії й пухлини плечового сплетення, шийні компресійні радикулопатії, синдром грудного отвору, хвороби мотонейрона, поперечний мієліт, патологія плечового суглоба, спондильоз, міофасціальний больовий синдром, костохондрит, гострий інфаркт міокарда, тромбоемболія легеневої артерії, комплексний регіонарний больовий синдром. Голкова електроміографія є визначальною в підтвердженні діагнозу СПТ, однак вона набуває інформативності лише через 2–3 тижні від початку захворювання. Магнітно-резонансна томографія плечового пояса у відновному періоді захворювання виявляє ознаки денервації м’язів плечового пояса, а в резидуальному періоді — ознаки атрофії м’язів і їх ліпідної інфільтрації. До цього часу не існує жодного методу лікування СПТ, що довів би свою ефективність у рандомізованих клінічних дослідженнях. Пероральний прийом преднізолону в гострому періоді захворювання асоціюється зі зменшенням больового синдрому і збільшенням імовірності повного функціонального відновлення. Менеджмент пацієнтів із СПТ передбачає адекватне нівелювання больового синдрому. Серед великої когорти нестероїдних протизапальних препаратів, що застосовуються для лікування гострого болю, все більше уваги приділяється декскетопрофену. Переваги декскетопрофену зумовлені його високою біодоступністю, швидким початком дії, різнорівневою (периферичною і центральною) активністю. На сьогодні в Україні декскетопрофен випускається у трьох формах (розчин для ін’єкцій, таблетки і гель) виключно як препарат Сертофен. Саме наявність різних форм Сертофену (декскетопрофену) дозволяє використовувати препарат як у стаціонарних, так і в амбулаторних умовах, а також дає можливість проводити ступінчасту протибольову й протизапальну терапію з наступним переходом на топікальну форму. При зменшенні больового синдрому активно застосовується фізична реабілітація, ортопедичні операції з метою фіксації лопатки.

Поширення коронавірусної інфекції 2019 (COVID-19) спричинило пандемію, ефективних методів лікування й вакцин поки що немає. COVID-19 значною мірою впливає на багато органів і систем організму, включаючи серце, кишечник, нирки та мозок, незважаючи на те, що зазвичай у клінічній картині переважають пневмонія і легенева дисфункція. При вивченні статистики, структури захворюваності та механізмів порушення органів та систем у хворих на COVID-19 виявлено головну закономірність: який би орган або система не були пошкоджені, вегетативна нервова система обов’язково буде порушуватися, а це впливатиме на результат перебігу коронавірусної інфекції. У зв’язку з цим були виявлені різні біомаркери та концептуальні теорії, при аналізі та узагальненні яких назріла необхідність визначити стратегію профілактики та лікування вегетативних порушень.

Agro photovoltaic: feasibility of synergistic system in the sugarcane bioenergy sector
Authors: Stefani Mario Antonio , Felema João
Published: February 2022

A feasibility analysis of the agro photovoltaic approach applied in the sugarcane energy sector is presented. A tailored architecture of photovoltaic implementation was designed to be installed above and on the same area of sugarcane plot without reduction of the planted area, respecting the agronomic requirements of the crop. Were analyzed mutual influences, necessary adjustments in crop handling, life cycle management, cross effects on agro-industrial costs and yields, potential savings, gains by additional electricity generation and improved economic results from synergies. The combined cross effects were applied in a hypothetical sugar-energy plant in the central region of the state of São Paulo, using typical figures and parameters of the 2019/2020 harvest season, based on updated sectorial reports, and using similarly typical parameters of photovoltaic plants. The greatest operational gain was due to the optimization and cost sharing with the exiting electricity generation on the thermal plant drive by biomass, and the highest relative incremental cost resulted from the photovoltaic installation, adapted conveniently to the special management and handling practices required by sugarcane crop. The approach proved economically feasible, respecting the agronomic conditions of the crop and the optimized use of the electric cogeneration infrastructure drive by biomass. The approach resulted on a significant increase in the revenues of energy cogeneration and the joint economic margin. The main feasibility constraints and check items are those related to the minimum negotiated average price of electricity, and to the CAPEX of the adapted photovoltaic architecture installation, strongly linked to the currency exchange ratio.

TRAUMA AND MEMORY IN POST-YUGOSLAV CINEMA
Authors:   University of Zagreb, Borjan Etami
Published: February 2022

The article discusses cinematic representations of memory and trauma in post-Yugoslav documentary and feature films that depict political and social reality in the post-socialist period. Through different modes of representation, from retrospective and testimonial to self-reflexive, post-Yugoslav films address important issues related to recent violent past. Since 1990s coming to terms with the past has been a central topic in public discourses and the complex and powerful role of memory in the formation of national identities has become a common topic in almost all artistic and cultural practices. Memory has become increasingly important in the construction of both individual and collective identity. As such, it has also become a site of struggle and identification. Contemporary post-Yugoslav filmmakers courageously tackle various issues related to collective memory, offering their point of view concerning events and personalities from Yugoslav history and the impact they have had on contemporary society. Younger generation filmmakers do not seek to perpetuate the nationalist discourse on war that marked the film production in the first post-socialist decade. The approach to recent history in their movies is more self-critical; the filmmakers reject self-victimization and self-exoticization and focus more on war-related guilt and embarrassment for the crimes committed by all belligerent sides.
Review of Facial Recognition Techniques
Authors: Nigam Harshit
Published: February 2022

Abstract: Facial Recognition, the biggest breakthrough in Biometric identification and security since fingerprints, uses an individual’s facial features to identify and recognize them. A technology that seems too farfetched taken straight from a science fiction novel is now available in smartphones in the palm of our hands. Facial Recognition has gained traction as the primary method of identification whether its mobile phones, smart security systems, ID verification or something as simple as login in a website. Recent strides in facial recognition technologies have made it possible to design, build and implement a facial recognition system ourself. Using Computer Vision and machine learning libraries like Facial Recognition and Dlib, we can create a robust system that can detect faces and then match and identify it with a database of pre-loaded facial data to successfully recognize them. This study conducted a literature review of these aforementioned technologies and various other advancements in the field of computer vision facial recognition by other scholars in their research papers. This paper analyzes domains to understand the working of these machine learning models and their different implementations in facial recognition systems. The research conducted by us during this review will be paramount in creating a proof-of-concept prototype facial recognition system.

Eigenstate entanglement scaling for critical interacting spin chains
Authors: Miao Qiang , Barthel Thomas
Published: February 2022

With increasing subsystem size and energy, bipartite entanglement entropies of energy eigenstates cross over from the groundstate scaling to a volume law. In previous work, we pointed out that, when strong or weak eigenstate thermalization (ETH) applies, the entanglement entropies of all or, respectively, almost all eigenstates follow a single crossover function. The crossover functions are determined by the subsystem entropy of thermal states and assume universal scaling forms in quantum-critical regimes. This was demonstrated by field-theoretical arguments and the analysis of large systems of non-interacting fermions and bosons. Here, we substantiate such scaling properties for integrable and non-integrable interacting spin-1/2 chains at criticality using exact diagonalization. In particular, we analyze XXZ and transverse-field Ising models with and without next-nearest-neighbor interactions. Indeed, the crossover of thermal subsystem entropies can be described by a universal scaling function following from conformal field theory. Furthermore, we analyze the validity of ETH for entanglement in these models. Even for the relatively small system sizes that can be simulated, the distributions of eigenstate entanglement entropies are sharply peaked around the subsystem entropies of the corresponding thermal ensembles.
Structure and mechanical properties of high strength austenitic Mn–Ni–Cu–V–C dispersionally hardened steel
Authors: Kostina M. V. , Blinov V. M. , Kalinin G. Yu. , Fomina O. V. , Mushnikova S. Yu.
Published: February 2022

The paper presents the results of a study of the structure and mechanical properties of high-strength austenitic dispersionally hardened Mn–Ni–V–C steel with a yield strength of at least 700 MPa. Its composition and the hardening method were selected so that the steel meets the requirements for high strength and nonmagnetic properties. It is shown that the introduction of 1–2% Cu into Mn–Ni–V–C steel expands the region of existence of the γ-phase in the Fe–Ni–Mn phase diagram, narrows the two-phase γ+α-region and shifts it towards lower Mn contents, increasing stability of austenite to martensitic transformation during cold deformation. A numerical assessment of the influence of alloying austenite-forming elements Ni, Mn, Cu on the critical degree of cold plastic deformation, leading to the formation of deformation martensite in steel, is proposed. The temperature range of the reverse transformation of this martensite into austenite during annealing is established, depending on the nickel content in the steel. For precipitation hardened steel with a composition of 10%Mn; 10%Ni; 2%Cu; 0.3–0.4%C; ~1.4%V the regularities of dissolution upon heating for quenching and precipitation during aging of particles of the strengthening carbide phase VC were studied. It has been shown that the maximum strength is achieved after quenching from 1150°C and aging at 650°C for 15 hours. Taking into account the studies carried out on the stability of austenite, static and cyclic strength and durability, the optimal alloying range of steel with nickel, manganese and copper was substantiated, and the optimal mode of heat treatment was revealed, which provides a combination of high strength with good ductility and toughness of steel.

When studying the high-temperature behavior of the heat-protective coating of zirconium dioxide, the method of laser heating has been tested. The coating was applied by the method of high-energy plasma spraying on the intermetallic sublayer of the Ni–Co–Cr–Al–Y system made of a powder material of the composition (ZrO2 + 7% Y2O3) of spherical morphology.

The aim of this work was to study the processes of structural-phase transformations, melting and crystallization occurring in a ceramic coating material under the action of a single laser pulse with a duration of 14 ms with different energies (5, 10, 15, and 20 J). It was found that after spraying, the coating in the initial state has a two-phase composition (T-ZrO2 + K-ZrO2), and a layered microstructure with a columnar structure of zirconium dioxide grains. Laser heating with a pulse energy of 5 J stimulates the phase transformation T-ZrO2 → K-ZrO2, the appearance of porosity and microcracks. With an increase in the pulse energy to 10 and 15 J, the processes of melting and ultrafast crystallization, accompanied by grain refinement, intensively occur on the coating surface. According to the theoretical estimates, the reflow processes affect surface layers with a thickness of 2.2 to 6.6 μm, and phase transformations take place at a depth of ~11 μm. With an increase in the laser pulse energy to E = 20 J, the process of destruction of the coating was initiated by the mechanism of cracking with delamination of fragments of the surface layer 5–10 μm thick.

The laser heating method is recommended as an express diagnostics for comparative tests of the heat resistance of ceramic coatings obtained by different methods and from different starting materials.

Published: February 2022

The paper presents the results of studies of the effect of the surface tension of the interstitial fluid on the structural and surface properties (specific surface area and pore volume, pore diameter distribution) of layered magnesium and aluminum double hydroxides (Mg-Al LDH) obtained by the interaction of AlCl3·6H2O, MgCl2·6H2O and ammonium carbonate. The equations connecting the specific surface area and the specific pore volume of the synthesized Mg-Al LDH samples with the surface tension of the interstitial medium are obtained. It is shown that the substitution of the aqueous medium in the pore space for acetone before drying the synthesized Mg-Al LDH allows to significantly increase the capacity of the adsorption monolayer of products and does not significantly affect the mechanism of the sorption process.

The paper studies deposition of a highly nickel-alloyed corrosion-resistant layer on the surface of a low-carbon economically alloyed steel. The formation of the layer is carried out in two stages – at the first stage, a precursor coating is applied by cold spraying, and at the second, an alloyed layer is formed on the surface by laser. A layer with a nickel content of up to 70% is formed on the surface of the steel. The results of X-ray diffraction phase analysis indicate that a face-centered cubic lattice of a solid solution and Ni3Fe intermetallic compound has been formed in the studied layer.

Published: February 2022

Raw milk has high nutritive value and is used as an important dietary supplement for humans. But, microbial contamination in milk has been a problem for era, while existing thermal technology often deteriorates the quality of milk and its valuable ingredients. Again, consumer demand for least processing technology without degradation of the product quality forced the scientist to develop novel methods relevant to the application of non-thermal technology which does not create any detrimental effect to the composition of milk are now being under scrutiny. One of the novel methods is plasma bubbling technique and is not yet examined for liquid foods like milk. In the present study, the plasma bubbling system was established for the decontamination of raw cow milk. The plasma bubbling was generated at voltage of 160V, for 5, 10 and 15 minutes (min) and was evaluated for microbial reduction at an air flow rate of 5 and 10 Litre/hour (L/h). It accounted for a maximum 1.33 log reduction for coliforms at 160V, flow rate of air was 10 L/h, for a 100mL of milk sample with 15 min exposure time, while for yeast the log reduction was 1.40. The plasma bubbled milk was analysed for its quality evaluation such as pH, acidity, colour and lactose content of milk. The value of pH was found to be 6.77 at 160V, 10L/h, 15 min and 100mL of sample volume while the control value of pH was 6.60. The findings from this study revealed that the atmospheric plasma bubbling system could be used for the pasteurisation of raw cow milk by reducing the microbial load without compromising milk quality. This work on novel atmospheric plasma bubbling is an initiative for the pasteurization of raw cow milk, which could have a potential impact on the food industry in future.

Thyroid hormones play an important role in the regulation of lipid metabolism. Subclinical hypothyroidism is defined as a slight increase in thyroid-stimulating hormone (TSH) with normal levels of thyroxine (T4). Hypothyroidism could be associated with altered lipid panels. This study aimed at evaluating the association between hypothyroidism and altered lipid profile. Data of 54 patients with subclinical hypothyroidism and 54 healthy individuals were collected from SBMCH laboratory. The participants belong to the age group of 20-50 years. Patients with TSH in the range of 4.2 to 10 mU/L, and T4 in the range 0.8 to 2.8 ng/dL were ruled out as hypothyroid. Control had a normal TSH ranging from 0.5 to 4.2 mU/L. The total serum cholesterol (TC), high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, and triglyceride (TG) levels were examined in both groups and the results were recorded. Participants with hypothyroidism had significantly higher LDL and lower HDL levels than the control group irrespective of age group and gender (P-value <0.001), but no difference in TG and TC levels (P-value <0.05) were observed. The prevalence of dyslipidemia and hypothyroidism was only significant in females (P-value =0.009). There was significant correlation between the prevalence of dyslipidemia and hypothyroidism regardless of gender (P-value =0.04). Hypothyroidism is associated with dyslipidemia, and biochemical screening for dyslipidemia is recommended in all patients with subclinical hypothyroidism.
