Changing environmental conditions can generate abiotic stress, such as the scarcity of water and exposure to chemicals. This includes biotic stress like Phytophthora palmivora infection, which causes leaf fall disease and inhibits the growth rate of para rubber seedlings, resulting in economic loss. To prevent abiotic and biotic stresses, biocontrol agents such as cyclic lipopeptides (CLPs) from Bacillus spp. have been introduced to reduce the use of chemically synthesized fungicides and fertilizers. This study aimed to use Bacillus CLP extracts as a biological agent to stimulate the plant growth system in para rubber seedlings under stress conditions compared with the exogenous plant hormone (salicylic acid, SA). CLP extracts obtained from B. subtilis PTKU12 and exogenous SA were applied to the leaves of para rubber seedlings. The extracted metabolites from each treatment were analyzed by untargeted metabolomics for metabolite identification and metabolic networks under stress responses. In both treatments, 1,702 and 979 metabolites were detected in the positive and negative ion modes of electrospray ionization, respectively. The differential analysis revealed that the accumulation of up-regulated metabolites in the treatment of CLP extracts was higher than in the exogenous SA treatment, belonging to 56 metabolic pathways. The analysis of metabolic pathways indicated that CLP extracts employed alanine, aspartate, and glutamate metabolisms for stress responses leading to plant growth promotion. These findings revealed that the metabolic network for plant growth promotion induced by BacillusCLP extracts could be considered a protective option for para rubber plantations.

Published: May 2023

As the third generation of IT is developing rapidly, higher education institutions in China are looking to produce innovation-minded talent who can adapt to the dual-mode IT work environments of modern enterprises to meet the demands of the intelligent manufacturing national development strategy. So, this research aims to specify the hierarchical talent training system and mechanism for information technology majors in the higher education system. A 1+2+X modular curriculum system was proposed for the information technology majors based on the group-chain development model that focuses on combining discipline and industry (also known as vertical and horizontal integration). The data analysis was performed through a comparative analysis of the talent training objectives of the Chinese institutes and course systems’ national development strategies. The results support the idea that the 1+2+X modular curriculum system can help universities produce innovation-minded talent by designing their curriculum based on the industry and trends rather than just focusing on specialization training. The novelty of this research is that it promotes the idea of professional development along with course training. This paper recommends that future researchers implement the concept in vocational institutes. Doi: 10.28991/ESJ-2023-07-03-024 Full Text: PDF

Background A three-day One Health training program for undergraduate and graduate students, as well as professionals in One Health-related fields, was conducted by the Philippine One Health University Network (PhilOHUN), in collaboration with the Southeast Asia One Health University Network (SEAOHUN), through a webinar series. To measure the impact of the training on the awareness, knowledge, attitude, and practices (A-KAP) related to the topics covered in the program, this study was conducted. Methods A quasi-experimental design was employed to evaluate the effect of the One Health training program on the A-KAP of the participants. An online questionnaire developed based on the content of the training modules was administered to the participants before and after the training program. The attendees who accomplished both the pre- and post-training A-KAP assessment questionnaire were included as study participants; of the 225 attendees, 119 respondents qualified. The difference between the pre- and post-training mean A-KAP scores of participants was determined using paired t-test. Results Findings showed that the Awareness of the participants (P<0.001) across the topics discussed significantly increased after taking part in the training program. In the Knowledge aspect, however, there was no significant improvement in the general knowledge items score of the participants (P=0.06) but improvements were observed in all the modules included in the training (P<0.05). As for the Attitude and Practices scores of the participants, no significant improvements were observed (P>0.05) after taking part in the training. Conclusions The significant differences in awareness and knowledge suggest that the training modules contain relevant topics, which were effectively transmitted during the program. For Attitude and Practices, it may be premature to determine the impact of a single activity, although it is expected that these will change over time. Nevertheless, the training program can be used as a springboard for introducing One Health concepts to a wider audience and a continuing initiative to influence the development of appropriate attitudes and practices for current and future One Health practitioners.

Pacing Induced Cardiomyopathy: What is The Solution?
Authors: Butarbutar Maruli Wisnu Wardhana , Raharjo Sunu Budhi 
Published: May 2023

ABSTRACT
Background
Right ventricular pacing is associated with adverse outcome including increased risks of cardiovascular morbidity and mortality. RV pacing causes abnormal ventricular activation results in an inefficient contraction pattern with ventricular dyssynchrony and loss of myocardial work that may lead to LV dilation, systolic dysfunction, and clinical HF. Pacing induced cardiomyopathy (PICM) is caused by chronic and high burden RV pacing that may occur several months or years after pacemaker implantation.

Objective
To present a case of pacing induced cardiomyopathy (PICM) managed by CRT-P implantation.

Case Illustration
A male, 56 years old, was referred from dr. M. Djamil General Hospital with CHF Fc II-III, s/p PPM DDDR due to high degree AV block (2016) and history of failed CRT-P implantation (2018). He complained DOE (+), PND (+) and OP (+) since April 2017. Physical examination revealed pansystolic murmur grade 2/6 at apex, no rales and no oedema at both legs. ECG showed pacing rhythm and intrinsic rhythm was type 2 second degree AV block and RBBB with QRS duration 150 ms. Echocardiography showed global hypokinetic and dilated LV (LV EDD 71 mm, LV ESD 63 mm) with progressively reduced EF 38% à 33% (Simpson), functional moderate MR and mild TR. CAG showed non-significant coronary artery stenosis with 20% stenosis at distal LAD. Patient was diagnosed as pacing induced cardiomyopathy (PICM). At catheter laboratory, there was stenosis of left subclavian vein. His-Bundle pacing (HBP) was planned at first, however CRT-P with biventricular epicardial pacing was then performed in which LV lead was inserted through right axillary vein. During follow up at general ward, ECG showed biventricular pacing rhythm. There was no signs and symptoms of heart failure. Patient was hospitalized for 3 days and then discharged in a good condition.

Summary
We reported a case of pacing induced cardiomyopathy in male patient 56 years old. Pacing induced cardiomyopathy is a complication of high burden RV pacing. Options to treat PICM once it has developed, or to prevent it from developing in the first place, may include conduction system pacing (e.g.: HBP) or CRT-P implantation.

Published: May 2023

Background: Cardiovascular diseases (CVDs) have been the leading cause of global deaths over the years. In Indonesia, coronary heart disease (CHD) is the most common CVDs, responsible for 29% of all deaths in 2017. East Nusa Tenggara is one of the provinces in Indonesia with the highest prevalence of CHD, which corresponded with growing cases of acute coronary syndromes (ACS). Therefore, we develop a registry to obtain patients' profiles as a basis for strategy development in ACS management.
Methods: A retrospectively observational study was conducted on all patients who presented with ACS between January 2019 and September 2020 at a general hospital in Kupang, East Nusa Tenggara. Data collected include demography, patient awareness and transfer history, risk factors, physical findings, diagnosis, workup, treatment, and mortality.
Results: A total of 282 patients with ACS (STEMI, 41,2%; NSTEACS, 58,8%) were included in this study. Most patients were male with a mean age of 58,2 ± 12,2 years and normal BMI (32.6%). Nearly 50% of all ACS patients have one or more comorbidities, followed by relatively low adherence to therapy. Half of the patients were referred, but only 16,9% of patients arrived at the first medical facility less than 1 hour after onset. Patients with NTSEACS had more risk factors than patients with STEMI. The median LOS was five days (range, 1-17 days) with 2,8% in-hospital death. The presence of patient and system delay might contribute to the low number of STEMI patients who received reperfusion therapy.
Conclusions: This research serves as the primary data for the improvement of acute coronary syndrome management in Kupang and East Nusa Tenggara.

Abstract
Infection caused by bacterial contamination is a critical problem challenging the successful use of medical implants in orthopaedic and dental applications. Consequently, medical implants with antibacterial abilities are in high demand. Tantalum and silver have been previously characterized to have excellent biocompatibility and antibacterial ability, but due to their significantly different properties, it is challenging to manufacture Ta-Ag components via thermal processing methods. Herein, by taking advantage of the unique characteristics of cold spray (CS) technology, an antibacterial Ta-Ag coating was successfully fabricated for the first time. In the CS process, blended Ta-Ag powders with different Ag concentrations were used to fabricate CS Ta-Ag coatings. Their antibacterial ability was preliminary tested and deposition behaviour was systematically investigated. The coating significantly reduced the metabolic activity of S. aureus bacteria, and a better deposition efficiency was obtained by blended Ta-Ag powder. It was found that soft Ag could aggregate in the coating and hard Ta particles were prone to rebound, which induced the peening effect for Ag and mass loss of Ta in the final coating Moreover, the clue of metallurgy bonding between Ta and Ag was detected in the region that experienced severe deformation despite their immiscibility.

Published: May 2023

Abstract
Developing a cost-effective fabrication method for devices containing metal channels with surface features on the submillimeter scale is essential for the development of novel, high efficiency micro-reactors and heat sinks. Traditional methods are limited by their high cost, low geometric accuracy, high energy consumption, and long processing times. This study presents a low-cost additive manufacturing method using twin wire arc spray to make surface features at the sub-millimeter scale. Water-soluble polyvinyl alcohol (PVA) paste is first placed onto a mold containing a negative of the desired surface features and allowed to cure. The cured PVA is removed from the negative and metal sprayed onto its surface. The deposited metal film was backed by epoxy for added rigidity. The PVA paste was then dissolved in a water bath, resulting in a metal surface with the surface features of the mold. Surface features with length scales as small as 200 μm were reproduced. Coating delamination was prevented by minimizing the temperature of the substrate during spraying by increasing the standoff distance and scanning speed of the spray torch.

Abstract
Cold spray (CS) technology has proven an enormous potential in the production of composite coatings, enabling a production of materials with superior qualities such as enhanced tribological behavior. This study aims to investigate the tribological properties of CS Al-based composite coatings reinforced by quasicrystalline (QC) particles. Two different Al alloys were used as the matrix, AA 6061 and AA 2024, and mixed with Al-based QC particles (Al-Cr-Fe-Cu) at different Al/QC ratios. A room-temperature ball-on-disc test was then used to evaluate the wear resistance of the CS composite coatings in air and compared to those of the CS non-reinforced Al alloy coatings as well as cast counterparts (AA 6061-T6). We have demonstrated that CS could be employed to produce dense and thick Al-QC composites. Further, the addition of the QC particles into the structure increased the wear resistance of the matrix resistance up to 8 times.

Abstract
Tailoring strength and ductility in additive manufacturing or repair is key to successful applications. Therefore, cold spraying must be tuned for maximum amounts of well-bonded internal interfaces as well as sufficient softening of the highly workhardened deposit. Zinc (Zn) with its low melting temperature is an ideal model system to study phenomena associated with high strain rate deformation and local temperature distributions, both, in single impacts and thicker deposits. Bonding and recrystallization can be facilitated by covering selected wide parameter regimes in cold spraying. Despite the low temperatures, Zn single splats already show recrystallization at internal interfaces, the respective amounts then scaling with increasing process gas temperatures. At higher process temperatures, deposits are almost fully recrystallized. The recrystallization seems to improve bonding at internal and at deposit-substrate interfaces. Under optimum conditions, an ultimate deposit cohesive strength of up to 135 MPa and an elongation to failure of 18.4% are reached, comparable to that of laser-manufactured or bulk Zn parts. This demonstrates a welltuned interplay between high amounts of bonded interfaces and softening by recrystallization that allows for deriving bulk-like performance of cold sprayed material without additional posttreatments. Correlations between microstructures, mechanical properties, and fracture mechanisms supply information about prerequisites needed for reaching high ductility as obtained in damage and failure modes of deposits and bulk materials in global and local approaches.

Published: May 2023

Abstract
Additive manufacturing with metal powders enables a high degree of design diversity and an enormous material flexibility for components. The development of new products using special alloys requires just a small amount of powder. Therefore, a wire arc spraying process using nitrogen is applied for powder production by atomizing. The remaining oxygen content, the nitrogen temperature and pressure in the atomizing chamber are monitored to ensure consistent quality. The power source enables direct current (DC) and alternating current (AC). Further parameters like basic current Iground, pulse current Ipulse, pulse duration tpulse, impulse frequency fpulse and alternating current frequency fAC can be varied. On the process side, the following parameters are recorded during the tests: current, voltage, wire feed speed and flow rate of the atomizing gas as well as oxygen content and temperature inside the spray chamber. These parameters have an influence on particle size and composition. The aim is to influence the melting behavior by electrical and other process parameters. The investigations are carried out on solid wires made of an iron-based alloy EN ISO 14341-A: G42 4 M21/2 C1 3 Si1, AWS A 5.18: ER 70-6.

Published: May 2023

Abstract
Temperature sensors are critical components in many industrial and research applications, particularly in harsh environments where high temperatures, corrosion and mechanical stress are prevalent. In this paper, we investigate the use of plasma spray technique as a versatile and simple method to print thermocouples and Resistance Temperature Detectors (RTDs) on metallic and ceramic substrates. The thermocouples based on NiCr-NiAl coatings were directly printed using thick metallic masks, while the RTD’s were structured using laser ablation. The manufacturing methods and the preliminary characterization of these temperature sensors are presented and discussed.

Published: May 2023

Abstract
With an increasing demand for lower fuel consumption of different means of transportation, the demand for lightweight construction materials is rising. In this frame, usually metallic parts can be replaced by components consisting of fiberreinforced plastics. On the other hand, the components lose their electromagnetic field (EMF) shielding properties, which are required for many applications such as housings for electrical components. This issue can be solved by applying electrically conductive foils or meshes, often by a manual process that increases the time of production and process. In this publication, the application and parameter influence of thermally sprayed electrically conductive coatings for EMFshielding applications is discussed. Laser structuring is used as a novel surface preparation process, for the subsequent thermal spray process. The influence of the used laser-parameters is discussed accordingly. The coatings are applied by the wire-arc spray with Zinc feedstock as well as the atmospheric plasma spray (APS) process with Copper feedstock. It was found that coating properties such as adhesion strength, EMF-shield strength as well as electrical properties are provided by the proposed technology.
Characterisation of Shrouded Plasma-Sprayed Al4C3-Ni Alloy Composite Coatings as Novel Bond Coats for TBCs
Authors: Kan Wen-Fa , Matthews Steven 
Published: May 2023

Abstract
Ni/Co-based alloys have been widely employed as bond coats (BCs) in thermal barrier coatings (TBCs) to provide oxidation resistance through the formation of a dense thermally grown oxide (TGO) layer. TGO thickening is a major contributor to TBC failure. Conventional approaches to minimize its growth have included refinement/optimization of the BC composition, deposition techniques, and post-treatments. However, these approaches have only led to incremental improvements in TBC performance and do not directly address the effect of the thin interfacial oxide layer on the TBC lifetime. In a shift from conventional thinking, the development of an Al4C3-Ni alloy composite BC aims to overcome the challenges generated by current TGOs. Post-deposition heat treatment tailors the coating microstructure to form a continuous internal carbide network. At elevated temperatures, the Al4C3 preferentially oxidizes to form an interlacing protective Al2O3 “root” that provides better TGO anchoring and reduces TBC thermal mismatch with the substrate. In this paper, the coatings were manufactured through gas-shrouded plasma spraying using various parameters to optimize the degree of inflight carbide dissolution and minimize the extent of coating porosity and cracking. XRD and carbon analysis were performed on the coatings and the microstructure was observed using SEM. Differences between coatings are discussed in relation to the spraying parameters.
Supersaturated Solid Solution Formation in the Metastable Eutectic High-Entropy Alloy Al0.3CoCrFeNiMo0.75 by Laser Metal Deposition and Degradation of Wear Resistance by Segregation
Authors: Preuß Bianca , Lindner Thomas , Lampke Thomas 
Published: May 2023

Abstract
In particular, eutectic HEAs (EHEAs) are of interest for coating technology. The microstructure of these multiphase systems is determined by the cooling conditions during solidification and the heat treatment condition. High cooling rates can suppress segregation and allow the formation of a supersaturated solid solution microstructure. Therefore, the property profile differs from that of the equilibrium state. The effect of cooling conditions on the functional properties of EHEA coatings has not been investigated so far. In the current study, the microstructure formation and wear resistance of the metastable EHEA Al0.3CoCrFeNiMo0.75 was investigated. Laser metal deposition (LMD) of the inert gas atomized powder forms a directional vertically solidified lamellar structure. A supersaturated solid solution and a metastable BCC and HCP phase was formed. The microstructure resembles a Widmanstätten structure. By spark plasma sintering (SPS), a statistically distributed orientation of the fine lamellae was produced. The highest microhardness and oscillating wear resistance were detected for the ultrafine LMD coating. By increase of the microstructure domain size, the hardness and oscillating wear resistance decrease. This study reveals the great potential of supersaturated solid solutions of ultrafine EHEAs obtained by LMD processing with high cooling rates.
