Published: November 2022

Abstract
The image-based measurement method 2D Continuous Particle Image Velocimetry (2D Continuous PIV) is commonly used for measuring particle velocities in thermal spraying processes due to its basic measurement setup and its large measurement volume compared to methods based on point sensors. The accuracy of such image-based measurement techniques depends on the measurement algorithm, the process environment, such as distributions of particle characteristics, and the error of the imaging system. However, in the case of 2D measuring, accuracy might also depend on the fact that 2D methods measure only two of the three velocity vector components while ignoring the third component. In this paper, the impact of measuring only two of the three velocity vector components on the accuracy of a closed-source 2D Continuous PIV algorithm is investigated. The analysis is based on a virtual measuring instrument that includes optical aberrations of the imaging system and it is shown that this error contribution of measuring only in 2D is within acceptable limits for typical thermal spraying processes.
A Substrate Surface Thermocouple for Thermal Spraying
Authors: Marr M. , Kesler O. 
Published: November 2022

Abstract
A substrate surface thermocouple was developed for thermal spraying. The substrate used for the study is a porous 430 stainless steel disk, though the thermocouple concept can be applied with other materials. Type N thermocouple wires are cemented in holes through the substrate, and then a copper coating is deposited across the surface to electrically connect the wire tips to complete the thermocouple circuit. The copper also promotes temperature equalization between the wire tips and the surrounding substrate surface to increase accuracy. Using finite element analysis (FEA), it was determined that the optimum thickness of the copper layer is 38 µm. With this thickness, the thermocouple should be able to measure peak-to-peak surface temperature swings due to a passing plasma jet within +/-3% when the copper thickness is uniform and all physical properties of the coating and substrate system are well-known. However, a number of assumptions were used for the FEA, so a detailed uncertainty analysis was performed. This analysis found that the expected accuracy window of the thermocouple is +19%/-10% as implemented for measuring surface temperature swings. For measuring average temperatures, the thermocouple is very accurate, because large heat fluxes into the substrate occur only when the plasma torch is directly in front of the substrate. Experimental measurements of surface temperatures with the optimized thermocouple are presented.
New Approach to Ceramic/Metal – Polymer Multilayered Coatings for High Performance Dry Sliding Applications

Published: November 2022

Abstract
The combination of thermally sprayed hard coatings with a polymer based top coat leads to multilayered coating systems with tailored functionalities concerning wear resistance, friction, adhesion, wettability or specific electrical properties. The basic concept is to combine the mechanical properties of the hard base coating with the tribological or chemical abilities of the polymer top coat suitable for the respective application. This paper gives an overview of different types of recently developed multilayer coatings and their application in power transmission under dry sliding conditions. State of the art coatings for dry sliding applications in power transmission are mostly based on thin film coatings like DLC or solid lubricants, e.g. MoS2. A new approach is the combination of thin film coatings with combined multilayer coatings. To evaluate the capability of these tribological systems, a multi-stage investigation has been carried out. In the first stage the performance of the sliding lacquers and surface topography of the steel substrate has been evaluated. For this purpose case-hardened steel substrates were laser textured and coated with different sliding lacquers. In the following stage thermally sprayed hard coatings were tested in combination with different sliding lacquers. For this test stage steel samples were coated with oxide ceramics, metal alloys and hard metals by high velocity flame spraying (HVOF) and high velocity suspension flame spraying (HVSFS). After a grinding process several types of sliding lacquers were applied by air spraying on the coated specimens. Wear resistance and friction coefficients of combined coatings were determined using a twin disc test-bed.

Authors: Azzo Nawfal , Daud Sulman Safa 
Published: November 2022

Background: One of the most important prognostic indicators in cancer is the lymph node dissection. Lymphadenectomy considered as a risk factor for deep vein thrombosis in patients with gynecological malignancy who underwent surgery. D-dimer was used to detect deep vein thrombosis, thus, it’s important to predict complications of post-operative Lymphadenectomy.
Objective: To predict the risk of deep venous thrombosis by used serum D-dimer and wells score after pelvic lymphadenectomy in gynecological cancer.
Patients and method: A cross sectional study conducted in Obstetrics and Gynecology/ ward in medical city, from 1st, January 2021 to 30th, Dec. 2021. A total number of 45 (22 endometrial, 12 ovarian and 11 cervical cancers).
Results: The mean±SD level of pre-operative D-dimer in patients with endometrial cancer was (423.2±123.9) while the mean±SD post-operative level was (987±125.1), the mean±SD level of pre-operative D-dimer in patients with ovarian cancer was (602±320.7) while the post-operative was (901.5± 412), mean±SD level of pre-operative D-dimer in patients with cervical cancer was (339±157) while the postoperative was (1214±327), and the mean±SD level of pre-operative D-dimer in all gynecological cancers was (541±167) while the post-operative was (1016±302). The mean±SD of wells score of those who are likely to developed DVT (n=7) in pre-operative was (2.3±0.02) while for those who are unlikely to develop deep vein thrombosis (n=38) was (2.03±0.4) with statistically significant difference (p=0.04) while highly significant difference found in pre- and post-operatively between the group of deep vein thrombosis (p˂0.001).
Conclusion: Highly significant increase of post-operative D-dimer in all gynecological cancer patients.
Assessing pandemic era stadium events and infections using mobile phone based population mobility data: An exploratory study from Ireland, 2021
Authors: Condron Aidan James , McGrath Guy , Madden Jamie 
Published: November 2022

Mass gathering events (MGEs) attracting local, national, or international crowds presented particular challenges in the context of the coronavirus disease 2019 (COVID-19) pandemic. Sporting, religious, music and other cultural events held during the early months of the pandemic, without social distancing or other safeguards, have been regarded as so-called ‘super spreader’ events. By the summer of 2020, MGEs were generally banned or subject to severe restrictions. Regular European sporting fixtures such as England’s Football Association and Germany’s Bundesliga matches began to return in the autumn with protective measures in place, such as matches initially held behind closed doors, and later with sub-capacity crowd limits and mandatory social distancing [1, 2, 3, 4, 5]. With protective measures in place, and proof of COVID-19 vaccination or recovery required for entry, a series of six sporting MGEs, ‘the All-Ireland Finals’ were held in the Republic of Ireland’s largest stadium, Croke Park in Dublin, during August-September 2021. This study draws on a high-resolution human population mobility dataset to quantify journeys to/from the stadium area on MGE days by destination. The anonymised, aggregated, data used is based on mobile phone usage, and consists of a series of fine-grained geographical origin-destination matrices presenting daily estimates of area to area journey numbers. With mobility from the stadium area serving as a proxy for MGE attendance, this study explores associations between MGE attendance numbers and local COVID-19 infections over subsequent five week periods. No evidence was found of association between attendance at any of the six 2021 All-Ireland MGEs and COVID-19 infections over subsequent five week periods. This finding contrasts with studies of comparable MGEs in 2020, such as English Association Football matches held during spring 2020, and German Bundesliga football matches held during autumn 2020. These differing outcomes may point to the effectiveness of transmission mitigation policies and behaviours.

The determinants of the income of crab fishermen are production results and prices. The purpose of this study was to examine how much the income changes of crab fishing fishermen in Lampopala Village, Rumbia District, Bombana Regency, Southeast Sulawesi during the Covid-19 pandemic which was carried out in January 2021. Respondents in this study were determined through themethod, cluster random sampling namely selecting fishermen who using traps and nets with a sample size of 10 trap fishermen and 10 net fishermen. Furthermore, themethod was census applied to all respondents by interview to obtain primary data on capture fishermen, namely name, age, education, business experience, amount of fuel, catch, fishing time, cost, and bait based on a structured questionnaire. The data obtained is then calculated using the formula for total costs, revenues, and revenues. The fishing process carried out by fishermen with traps and nets is the same, namely the preparation of fishing gear, including engines, boats, fuel, consumption, and bait as well as the selection oflocations fishing ground. The income of bubu fishermen is an average of Rp.4,030,449/month during Covid-19. Meanwhile, the average income of net fishermen is Rp. 3,183,813/month during Covid-19. The production of trap fishermen during Covid-19 remained at 180 kg/month but with increased profits to Rp. 5,429,652. On the other hand, the production of net fishermen has decreased to 120 kg/month with a profit of Rp. 3,204,766 during Covid-19. The thing that causes a decrease in the profits of fishermen catching nets is the reduced amount of production caused by constraints such as torn nets and restrictions on activities by the government. The crab fishermen have increased the selling price of the crab which was originally between Rp.30,000 before Covid-19 to Rp.35,000 during Covid-19. Most of the crabs are sold to companies/collectors so that they can increase the income of crab fishermen. Keywords: Traps, Nets, Income, Crabs, Covid-19
