Preparation and Characterization of WC/Co-W-C Cermet Coatings with Molten Zinc Corrosion Resistance by HVOF Spraying of Bimodal-Structured WC/Co Powder
Authors: Xu J.-M. , Tan X.-H. , Wang Q. , Li Q. , Yang G.-J. , Wang Y.-Y. , Li C.-X. , Li C.-J. 
Published: June 2023

Abstract
In this study, WC-CoWC coatings were produced by HVOF spraying using bimodal-structured WC-Co powder with both micro- and nano-sized WC particles. Due to the melting characteristics of the powder during spraying, the microsized particles are retained in the deposit, but the nanosized particles dissolve into the Co matrix, forming a Co-W-C ternary phase. Compared to coatings sprayed from conventional WC-CoWC powder, the bimodal coatings are more resistant to corrosion and wear and are comparable in microhardness.

Published: June 2023

Abstract
This study investigates the development of fatigue failure in steel specimens coated by various spraying methods with and without grit blasting. Commercial titanium powder was deposited on structural steel substrates by low-pressure and portable cold spray as well as plasma and warm spray. Coating samples were subjected to strain-controlled cyclic bending, while monitoring resonant frequency as a measure of accumulated damage. A change in frequency of 4 Hz was chosen as the test-stop with the corresponding cycle count serving as the main indicator of fatigue life. Test results are presented in the paper along with explanations of fatigue mechanisms and process-related factors.

Abstract
This study investigates the effects of operating environment and temperature on the friction behavior of self-mated WC-CoCr coatings in sliding contact. Nickel superalloy substrates were coated with 86WC-10Co-4Cr powder using a warm spray gun. Coating cross-sections and surfaces were examined by SEM, XRD, EDX, and x-ray photoelectron spectroscopy (XPS). Tribological tests were conducted on a high-load tribometer at various temperatures in air, nitrogen gas, and distilled water. Test samples were examined by SEM and XPS, revealing wear patterns and elemental compositions while providing insights on oxide formation.
Investigation of Crack Propagation Behavior of Thermal Barrier Coatings Fabricated by Atmospheric Plasma Spraying in the Process of Uniaxial Tension Using Acoustic Emission Technique
Authors: Wang L. , Zhong X. H. , Zhao Y. X. , Zhao H.Y. , Yang J. S. , Tao S. Y. , Wang Y. 
Published: June 2023

Abstract
In this study, acoustic emission sensing is used to monitor interfacial cracking in thermal barrier coatings during uniaxial tensile adhesion testing. The TBCs consist of a ZrO2 topcoat and a NiCrAl bond coat, both of which are applied by atmospheric plasma spraying. Tensile testing was performed to failure and the resulting fracture surfaces were examined by SEM and XRD analysis. Experimental results show that cracks usually initiate in the ceramic layer then propagate toward the metallic-ceramic interface where failure occurs. Finite element simulations were also conducted, confirming the experimental findings.
Examination of the Characteristics of Residual Pores in High Temperature Sintered Plasma-Sprayed La2Zr2O7 Coatings
Authors: Liu T. , Chen X. , Yang G.-J. , Li C.-X. , Li C.-J. 
Published: June 2023

Abstract
In this study, La2Zr2O7 coatings produced by atmospheric plasma spraying were heated to 1300°C for up to 100 h. Residual pores in the coatings were characterized by SEM. Porosity was found to decrease with increasing sintering duration, although large pores still existed after 100 h. The relationship between the opening of residual pores and sintering time was closely analyzed and is described in detail. The results presented in the paper can inform the design of pores that endow TBCs with higher sintering resistance.
The Analysis of Possible Application of Different Working Gases in Cold Gas Spray Method: Dynamics and Temperatures of Particles
Authors: Małachowska A. , Ambroziak A. , Pateyron B. , Pawłowski L. 
Published: June 2023

Abstract
The paper analyzes different working gases and their mixtures for possible application in cold gas spraying (CGS). The gases considered include Ar, CO2, and steam, alone and in combination. Typical pressures and temperatures were used, along with CFD simulation software, to calculate gas velocity profiles along the axis of a convergent-divergent nozzle. The profiles are compared with that of nitrogen, the standard gas for cold spray, flowing under the same conditions. Velocity and temperature profiles were also calculated for copper particles in the various gas flows as well as nitrogen. Differences in temperature and velocity are explained based on sonic velocities, viscosities, and thermal conductivities of the respective gases.
Solid Abrasive Wear Behavior of Cr3C2-20(NiCr) Deposited by HVOF
Authors: Altuncu E. , Ustel F. 
Published: June 2023

Abstract
This study assesses the abrasive wear resistance of Cr3C2-NiCr coatings produced by HVOF spraying. Abrasion tests were conducted in a three-body solid-particle rubber-wheel test rig using silica and alumina grits under different loads. The results indicate that abrasion performance is controlled by cohesion between splats, which can be further improved. The removal of carbide particles was the main wear mechanism and is controlled by the content and size of the Cr3C2 particles. It is shown that the abrasive wear resistance of carbide-based cermet coatings is significantly higher than that of mild steel.

Evaluation of black seed (Nigella sativa L.) cake and its protein in muffins as a valuable potential functional source for obesity control
Authors: Kamandloo Farzaneh , Miran Mona , Salami Maryam 
Published: June 2023

Background:Due to the use of high-calorie foods and reduced physical activity caused by the modern lifestyle, obesity is on the rise. Obesity occurs by the increase of fat accumulation in the body, causing different complications such as diabetes, cardiovascular diseases, cancer, respiratory disorders, blood pressure, etc., which has become a global problem. Objectives:The production of functional food that has medicinal properties for controlling or inhibiting diseases is increasingly popular. With the expanding concerns about obesity and its related diseases, it is very important to provide natural controlling or inhibiting compounds. In this study, the functional properties of black seed cake (BSC) and its protein (BSCP) were investigated for obesity control through the inhibition of pancreatic lipase, α-glucosidase, and α-amylase enzymes as well as its antioxidant properties. Methods:The textural properties and sensory evaluation of muffins, enzyme inhibition properties (inhibiting the effect of enzymes in the obesity process), and antioxidant properties (control or inhibition of side effects caused by body fat oxidation) of BSC and BSCP were investigated.Results:The highest and lowest inhibitory levels of pancreatic lipase are related to black seed (Nigella sativa)cake protein (BSCP) (59.21%) and black seed cake (BSC) (32.90%), respectively. The highest and lowest levels of α-amylase inhibition are related to BSCP (32.51%) and black seed cake in ethanol 75% (BSC-E75%) (3.62%), respectively. The highest and lowest α-glucosidase inhibitory levels are related to BSC-E30% (71%) and BSCP (10.10%), respectively. BSC and BSCP showed high antioxidant activity. The use of BSC and BSCP in the production of muffins (a widely consumed and popular product) to replace flour and oil in the formulation of muffins caused a decrease in L*, b*, but an increase in a*. Hardness, chewiness, springiness, and cohesiveness decreased with the increase of BSC and BSCP content. Samples BSM 3%, BSM 6%, PBM 1%, and PBM 2% were similar to control muffins in sensory evaluation.Conclusions :From the result of this study, it can be concluded that black seed cake and its protein can be considered a potential efficient source for the production of functional muffins and possibly other functional foods that aim to manage and control obesity, blood glucose, and blood fat. However, more research is needed to fully determine the effectiveness of black seed cake and its protein.Keywords: Obesity, Black seed cake, Muffins, Diabetes, Blood pressure, Blood fat
Autonomous Architecture: The Hybridization of the Dwelling and Mobility Device.
Authors: Filice Daniel Julian Frank 
Published: June 2023

<p> It is the static nature of the dwelling that has influenced how we perceive our concept of home. As the contemporary world continues to establish new connections, interweaving both physical and technical networks to challenge the ever-present barriers of mobility, the dwelling remains disassociated and dormant. The thesis proposes that the notion of agency may offer an alternative perspective from which non-human actors may participate in the design of human ecologies through the process of translation. It is translation defined as the mobilization of a common collective that the hybridization of the dwelling and mobility device may affect our conception and experience of home life. </p>

<p>Introduction</p>
<p>Black people are disproportionately impacted by homicide. However, despite this overrepresentation, research is limited relevant to how black individuals, families and communities cope with the chronic traumatic devastation of homicide. This scoping review will provide an amalgamation of the current literature regarding the coping strategies of black survivors of homicide victims to inform future health and social work practice. </p>
<p>Methods and analysis </p>
<p>In this scoping review, Arksey and O’Malley’s five-stage framework will be used to succinctly gather and synthesise previous literature and identify gaps in research relevant to black survivors of homicide victims. This method will allow for a focused process of chosen pertinent databases. The seven databases include OVID (MEDLINE and PsycINFO), ProQuest (Sociological Abstracts, Social Services Abstracts, International Bibliography of Social Sciences), EBSCO (Africa Wide, The Cumulative Index to Nursing and Allied Health Literature). The seven databases were chosen for their relevance to the topic of coping with homicide for black individuals, families and communities. All members of the research team will screen the abstracts and full texts of the literature based on the inclusion criteria. The findings will be charted and synthesised using a qualitative thematic analysis. </p>
<p>Ethics and dissemination </p>
<p>The articles chosen for this review will be gathered from peer-reviewed journals and scholarly search engines. Due to this research project’s nature, ethics approval is not warranted. The results of this scoping review will inform culturally responsive approaches to research, policy and practice for first responders (eg, law enforcement, emergency medical technicians) and providers (eg, mental health clinicians, physicians and faith-based communities) who frequently render services to black survivors of homicide victims. The results will be shared through journal article publications, academic and community conferences, as well as professional training opportunities for practitioners who support Black individuals, families and communities</p>

Published: June 2023

Abstract
Speleothems found in caves worldwide are considered the natural libraries of paleontology. Bacteria found in these ecosystems are generally limited to Proteobacteria and Actinomycetota, but rare microbiome and “Dark Matter” is generally under-investigated and often neglected. This research article discusses, for the first time to our knowledge, the diachronic diversity of Actinomycetota entrapped inside a cave stalactite. The planet’s environmental microbial community profile of different eras can be stored in these refugia (speleothems). These speleothems could be an environmental “Microbial Ark” storing rare microbiome and “Dark Matter” bacterial communities evermore.

Abstract
Freshwater fish are often exposed to threats from anthropogenic or natural origins, such as pathogenic or opportunistic microorganisms responsible for a broad range of severe infections.
In this study, we aimed to assess this microbiological threat to fish in an Algerian northwestern dam Sekkak (Tlemcen) by evaluating the diversity of ichtyopathogenic bacteria. In order to determine the water quality, physicochemical analyses of the dam water were carried out in situ. Ichtyopathogenic bacteria were isolated on selective media and identified by API galleries and molecular techniques (PCR and sequencing of the 16S rRNA gene). Besides, the antibiograms were constructed for all the isolates.
The physicochemical and bacteriological analyses allowed us to classify the dam water as moderately polluted to polluted. Furthermore, an important diversity of ichtyopathogenic bacterial species was observed as Aeromonas hydrophila, Providencia rettgeri, and Pseudomonas aeruginosa were retrieved. The antibiogram test revealed notable resistance. The antibiotic family for which most resistances were found was the β-lactam family, followed by aminoglycosides and macrolides. These results indicate that aquatic environments can shelter multidrug-resistant pathogenic bacteria representing a threat to the endemic fauna. Therefore, it is important to closely monitor these waters in order to improve the fish’s living environment and ensure healthier production.

Authors: Sutandar Vivi Hendra , Maritska Ziske 
Published: June 2023

Background: Tuberculosis is a disease caused by Mycobacterium tuberculosis. Indonesia ranks second worldwide in TB incidence in the country.
Content: The spread of the disease is happening across Indonesia. Each area of Indonesia had different types of lineage M. tuberculosis and TB incidence number. Drug resistance is threatening to society and it needs full attention and immediate medication to control the disease. Therefore, this paper is composed of reviews from 10 journals that reported drug resistance TB in several different locations in Indonesia using different methods available.
Conclusion: The number of TB cases and their lineages differ in each area in Indonesia, one of which is due to the availability of diagnostic tools and level of self-awareness in each area. There are reported findings of drug resistance TB in Indonesia that are concerning. Currently, many TB treatments are under development to produce the best therapy to treat the disease.

Authors: Nazrin Tahera , Hassan M Quamrul 
Published: June 2023

Infective endocarditis (IE) is the infection of endocardial surface of the heart. IE is the rare disease with significant complications which require early diagnosis and proper treatment for reducing morbidity and mortality.IE with vegetation on pulmonary valve, leaflets are uncommon. However, we have diagnosed one case with infective endocarditis associated with Multisystem Inflammatory Syndrome in Children (MIS-C) which is related with COVID-19. MIS-C is commonly associated with coronary artery aneurysm (CAA), myocarditis and heart failure. Our patient had IE and was subsequently affected with MIS-C due to COVID. The child had vegetation on pulmonary valve with flail pulmonary valve-leaflet with grade II pulmonary regurgitation and MIS-C related CAA. The second child was previously diagnosed as infective endocarditis and was treated in other hospital for intravenous antibiotic for four weeks. However, in our hospital he was diagnosed clinically, by laboratory investigations and by echocardiography as MIS-C with large vegetation, which was surgically removed, and biopsy revealed mycobacterium tuberculosis as causative organism.

Published: June 2023

Background: Complex bone plateau fractures have been treated with bilateral plate fixation, but previous research has overemphasized evaluating the effects of internal fixation design, plate position, and screw orientation on fracture fixation stability, neglecting the internal fixation system’s biomechanical properties in postoperative rehabilitation exercises. This study aimed to investigate the mechanical properties of tibial plateau fractures after internal fixation, explore the biomechanical mechanism of the interaction between internal fixation and bone, and make suggestions for early postoperative rehabilitation and postoperative weight-bearing rehabilitation.Methods: By establishing the postoperative tibia model, the standing, walking and running conditions were simulated under three axial loads of 500 N, 1000 N, and 1500 N. Accordingly, finite element analysis (FEA) was performed to analyze the model stiffness, displacement of fractured bone fragments, titanium alloy plate, screw stress distribution, and fatigue properties of the tibia and the internal fixation system under various conditions.Results: The stiffness of the model increased significantly after internal fixation. The anteromedial plate was the most stressed, followed by the posteromedial plate. The screws at the distal end of the lateral plate, the screws at the anteromedial plate platform and the screws at the distal end of the posteromedial plate are under greater stress, but at a safe stress level. The relative displacement of the two medial condylar fracture fragments varied from 0.002–0.072 mm. Fatigue damage does not occur in the internal fixation system. Fatigue injuries develop in the tibia when subjected to cyclic loading, especially when running.Conclusion: The results of this study indicate that the internal fixation system tolerates some of the body’s typical actions and may sustain all or part of the weight early in the postoperative period. In other words, early rehabilitative exercise is recommended, but avoid strenuous exercise such as running.

Published: June 2023

Microbial induced carbonate precipitation (MICP) through the ureolysis metabolic pathway is one of the most studied topics in biocementation due to its high efficiency. Although excellent outcomes have proved the potential of this technique, microorganisms face some obstacles when considering complicated situations in the real field, such as bacterial adaptability and survivability issues. This study made the first attempt to seek solutions to this issue from the air, exploring ureolytic airborne bacteria with resilient features to find a solution to survivability issues. Samples were collected using an air sampler in Sapporo, Hokkaido, a cold region where sampling sites were mostly covered with dense vegetation. After two rounds of screening, 12 out of 57 urease-positive isolates were identified through 16S rRNA gene analysis. Four potentially selected strains were then evaluated in terms of growth pattern and activity changes within a range of temperatures (15°C–35°C). The results from sand solidification tests using two Lederbergia strains with the best performance among the isolates showed an improvement in unconfined compressive strength up to 4–8 MPa after treatment, indicating a high MICP efficiency. Overall, this baseline study demonstrated that the air could be an ideal isolation source for ureolytic bacteria and laid a new pathway for MICP applications. More investigations on the performance of airborne bacteria under changeable environments may be required to further examine their survivability and adaptability.
