Authors: Tillmann W. , Schaak C. , Krekler B. 
Published: January 2023

Abstract
The ongoing development of new HVOF spray guns for internal diameters is driving demand for finer spray powders. Fine spray powders (&lt; 20 µm) are necessary to achieve short spray distances, but they also create new challenges. The first steps in the thermal spray process chain are powder preparation and feeding. If these steps are not stable, no sufficient coating quality can be obtained. This present work compares volumetric and fluidization powder feeding methods and investigates the feeding behavior of agglomerated and sintered WC-Co(Cr) powders with particle fractions of -5+15 µm, -20+5 µm, and -10+2 µm. Particle size fraction was measured ex situ by laser diffraction and particle outflow from the injectors was recorded in-situ by means of particle image velocimetry.
Bioinspired Mechanically Robust Metal-Based Water Repellent Surface Enabled by Scalably Constructing a Flexible Coral-Reef Like Cu-Based Architecture
Authors: Luo Xiao-Tao , Li Chang-Jiu 
Published: January 2023

Abstract
This study assesses the durability of superhydrophobic surfaces that possess a scalable architecture similar in morphology to branching or corymbose coral. In the experiments, electrolytic copper powders with a coral-like morphology are cold sprayed onto metal, ceramic, and glass substrates, forming a textured copper layer with a structural hierarchy based on the morphology of the powder. After cold spraying, a flame treatment is applied, creating a porous layer of Cu2O over the pliable Cu surface, which further increases roughness. As a final step, a fluoroalkyl silane spray is applied to reduce surface energy. It is shown that the fluorinated surface retains its excellent water repellency after cyclic bending and folding, sand-grit erosion, knife-scratching, and even heavy loading with simulated acid rain. It also retains its adhesion to glass (17 MPa), ceramic (12 MPa), and metal (34 MPa) substrates.

Published: January 2023

Abstract
Ceramic coatings are often applied to metallic substrates using a bond coat to promote adhesion. The corrosion environment between the substrate and ceramic layer can be very harsh due to the absence of dissolved oxygen, high concentrations of corrosive electrolytes, and galvanic and crevice corrosion mechanisms within the bond coat itself. This study assesses the performance of several bond coats in sulfuric acid, including plasma sprayed tantalum and HVOF sprayed NiCr, Hastelloy C, and Ultimet. The bond coats were deposited on Hastelloy substrates and covered with a Cr2O3 topcoat. Electrochemical polarization and open circuit potential measurements were recorded and coating microstructures were examined before and after the corrosion tests. Plasma sprayed tantalum exhibited the best corrosion resistance at room temperature, followed by HVOF sprayed Hastelloy C.

Authors: Kanno Akihior , Takagi Kaito 
Published: January 2023

Abstract
This study investigates the cavitation erosion (CE) behavior and fracture morphology of tungsten carbide thermal spray coatings. WC-CoCr and WC-CrC-Ni powders of various sizes were deposited on stainless steel substrates by HVOF spraying using different combustion pressures. Coating samples and Cr steel reference specimens were subjected to vibratory cavitation erosion tests, volume loss was measured, and erosion damages were examined by SEM to assess fracture morphology. The results indicate that CE resistance can be improved by reducing porosity and increasing interparticle bonding strength.

Published: January 2023

Abstract
This study compares the performance of different measurement methods for characterizing particles during thermal spraying. The accuracy of double-point and single-point measurements is assessed in the context of HVOF and suspension plasma spraying (SPS) where in-flight particle temperature and velocity are recorded for different powders and suspensions. The results are evaluated by analyzing splats and correlating their size and shape to in-flight particle temperature measurements. It is shown that particle diagnostic systems based on single-point measurements are well suited for SPS and HVOF processes.

Published: January 2023

Penyelenggaraan pelayanan prasarana dan sarana (P&S) permukiman, termasuk diantaranya penyediaan air minum telah menjadi tanggung jawab Pemerintah Daerah Tingkat II (kota maupun kabupaten). Untuk menjamin penyelenggaraan penyediaan air minum yang memenuhi syarat kualitas, kuantitas dan kontinuitas, maka diperlukan suatu standar pelayanan. Sampai akhir Pelita VI, prasarana dan sarana permukiman (PSP) yang dibangun, belum mencapai standar pelayanan minimal yang ditetapkan., sehingga banyak yang sudah tidak berfungsi sebelum umur ekonomisnya berakhir. Oleh karena itu dilaksanakan suatu kajian standar pelayanan minimal dengan suatu metodologi penelusuran pustaka dan informasi ilmiah dari buku, jurnal, laporan penelitian dan internet. Komponen materi standar pelayanan bidang air minum mencakup 3 bagian utama, yaitu yang berhubungan dengan bidang pemrograman, pelaksanaan oleh operator dan pemanfaatan oleh masyarakat. Ketiga bidang tersebut pada dasarnya mempunyai kaitan yang erat satu sama lain. Dalam pembahasan ketiga materi standar ini dibagi dalam klasifikasi tipikal perkotaan, yaitu kota kecil, kota sedang, kota besar dan kota metropolitan. Untuk penyelenggaraan pelayanan dan penyusunan standar daerah disesuaikan dengan kondisi spesifik daerah masing-masing, namun masih dalam kriteria-kriteria yang distandarkan. Materi teknis dengan hasil berupa komponen biaya satuan program dan biaya operasional. Penetapan standar pelayanan minimal PSP dapat digunakan sebagai acuan perencanaan, pemrograman, pelaksanaan, monitoring dan evaluasi serta tindak lanjut pengembangannya

Published: January 2023

Meningkatnya kandungan CO2 di atmospher telah menyebabkan efek gas rumah kaca, yang mengakibatkan naiknya temperatur bumi, sehingga terjadi pencairan cadangan es di kutub utara dan selatan serta cadangan es di dataran tinggi. Peningkatan gas CO2 disebabkan oleh proses pembakaran yang dibutuhkan dalam menjalankan sarana dan prasarana penunjang kehidupan kehidupan dan penghidupan manusia. Bangunan gedung berpeluang mengeluarkan 30% dari total emisi CO2 yang dihasilkan oleh kehidupan manusia. Terdapat 2 cara emisi CO2 yang berasal dari bangunan, yaitu emisi CO2 yang dihasilkan ketika proses pembangunan (embodied CO2 emission) serta emisi CO2 yang dihasilkan pada pemanfaatan bangunan. Konsep green building adalah salah satu pendekatan untuk menjamin terjaganya kualitas lingkungan agar tetap langgeng. Salah satu indikatornya adalah bangunan tersebut harus mengkonsumsi energi secara efisien sampai dengan zero energy. Namun nyatanya pemanasan global belum dapat diukur oleh besar konsumsi energi, akan tetapi dari besarnya emisi CO2 yang dihasilkan oleh bangunan. Hal tersebut disebabkan, besarnya emisi CO2 yang dihasilkan oleh setiap pembangkit listrik memiliki nilai yang berbeda-beda. Pembangkit listrik tenaga uap dengan batu bara menghasilkan emisi CO2 940 gr CO2 setiap 1 kWh, sedangkan energi listrik tenaga diesel menghasilkan 581 gr CO2 untuk 1 kWh. Sebagai upaya mitigasi terhadap pemanasan global, sudah saat-nya, besarnya emisi CO2 yang dihasilkan oleh bangunan tersebut dikendalikan. Proses pengendalian dapat dilakukan pada tahap perencana an maupun tahap pelaksanaan, sebagai upaya untuk menurunkan emisi CO2 yang dikandung oleh bangunan. Untuk menunjang proses perencanaan bangunan gedung rendah emisi CO2 tersebut diperlukan tools, yang berfungsi untuk mengukur/menghitung besarnya emisi CO2 pada bangunan. Tools tersebut akan memberi informasi besarnya harga satuan emisi CO2 pada bangunan gedung per meter persegi (HSEBG).

BACKGROUND: Melanoma is a tumor caused by melanocytes with a high degree of malignancy, easy local recurrence, distant metastasis, and poor prognosis. It is also difficult to be detected by inexperienced dermatologist due to their similar appearances, such as color, shape, and contour. OBJECTIVE: To develop and test a new computer-aided diagnosis scheme to detect melanoma skin cancer. METHODS: In this new scheme, the unsupervised clustering based on deep metric learning is first conducted to make images with high similarity together and the corresponding model weights are utilized as teacher-model for the next stage. Second, benefit from the knowledge distillation, the attention transfer is adopted to make the classification model enable to learn the similarity features and information of categories simultaneously which improve the diagnosis accuracy than the common classification method. RESULTS: In validation sets, 8 categories were included, and 2443 samples were calculated. The highest accuracy of the new scheme is 0.7253, which is 5% points higher than the baseline (0.6794). Specifically, the F1-Score of three malignant lesions BCC (Basal cell carcinoma), SCC (Squamous cell carcinomas), and MEL (Melanoma) increase from 0.65 to 0.73, 0.28 to 0.37, and 0.54 to 0.58, respectively. In two test sets of HAN including 3844 samples and BCN including 6375 samples, the highest accuracies are 0.68 and 0.53 for HAM and BCN datasets, respectively, which are higher than the baseline (0.649 and 0.516). Additionally, F1 scores of BCC, SCC, MEL are 0.49, 0.2, 0.45 in HAM dataset and 0.6, 0.14, 0.55 in BCN dataset, respectively, which are also higher than F1 scores the results of baseline. CONCLUSIONS: This study demonstrates that the similarity clustering method enables to extract the related feature information to gather similar images together. Moreover, based on the attention transfer, the proposed classification framework can improve total accuracy and F1-score of skin lesion diagnosis.
A Survey on Translation as a Learning Strategy by EFL Higher Education Students in English Learning
Authors: Edelia Alfira Dewi , Maharsi Ista 
Published: January 2023

Many language teachers assume that the use of translation as a learning strategy to learn a language can harm the learning processes. In contrast, many learners need translation as a learning strategy to help them understand the meanings of texts. This paper reports on the use of translation strategies in English learning by EFL higher education students at an Islamic private university. This study employed a survey study. Data were collected from the Inventory for Translation as a Learning Strategy (ITLS) questionnaire consisting of 27 items that were adapted from Liao (2002). The participants were 97 students who enrolled in the English Education major batch of 2018 and they were randomly selected. Findings show that the most frequent strategy use of translation is the use of electronic machines and English-Indonesia and Indonesian-English dictionaries (M=4.15 and SD= 0.91). Meanwhile, the least frequent strategy use of translation is to ask questions to peers and seek to find the meaning of idioms and expressions collectively in searching for unknown or new information about the English language (M=2.63 and SD=1.14).

ABSTRACTObjective: To determine the prevalence of hearing loss and otologic diseases among Filipinos living in the Southern Tagalog Region IV-A: CALABARZON (Cavite, Laguna, Batangas, Rizal and Quezon), Philippines.

Methods:
Design: Retrospective Review of Community Survey Data
Setting: Communities in Region IV-A provinces, Philippines
Participants: 3267 residents of the five provinces aged 0 months and above

Results: About 71.29% and 74.60% had at least mild hearing loss, in right and left ears, respectively. For disabling hearing impairment, overall prevalence was 26.33%, distributed into 11.87% among 4 to 18-year-olds; 8.97% for 19 to 64-year-olds; and 3.17% for 65-year-olds and above. Absence of prevalent and hearing loss-associated diseases: serous otitis media [OR 0.362, 95% CI 0.167 to 0.782, p = .010], CSOM [OR 0.407, 95% CI 0.236 to 0.703, p = .001] COM [OR 0.229, 95% CI 0.106 to 0.494, p < .001] can decrease the risk for hearing loss development in the region. Prevention of noise-induced hearing loss or delay in the manifestation of presbycusis can reduce the risk of having hearing loss by as much as 75% [OR 0.253, 95% CI (0.180 to 0.355), p < .001]. All pure tone audiometry measurements were obtained with surrounding median ambient noise of 55dB (IQR 46 to 60dB).

Conclusion: The prevalence of hearing loss among surveyed residents of the Southern Tagalog Region IV-A provinces was high compared to the previous nationwide study but low compared to other low- and middle-income countries. The top otologic conditions of this population (ear occlusion with ear wax, chronic suppurative otitis media, chronic otitis media, presbycusis, noise- induced hearing loss) were associated with hearing loss and their absence decreased the risks for hearing impairment.
