Hot-tail electrons’ impact on assimilation and injection penetration of D2 shattered pellet injections
Authors: Hu D. , Liu C. , the JOREK Team  
Published: June 2022

Abstract
The assimilation and the penetration of injected materials play significant roles in the mitigation efficiency of shattered pellet injection (SPI) as a disruption mitigation system (DMS), hence an accurate description of the fragment ablation rate is desirable. Current mainstream 3D MHD codes modelling SPIs mostly assume instantaneous thermalization between the previously hot ambient electrons and the newly released cold electrons. This could result in underestimation of the ablation rate if the hot electron thermalization time is comparable or even longer than the fragment flying time across flux tubes, putting the validity of these 3D SPI simulations into question. To resolve this doubt, we hereby investigate the thermalization dynamics and the overall hot-electron impact. The finite-time collisional thermalization of hot-tail electrons in a rapidly cooling plasma, as well as the so-called ‘self-limiting’ effect are considered. The former effect tends to deplete the colder population within a hot-tail species, while the latter is found to preferentially deplete the higher energy population. The combined result is found to cause an almost self-similar decay of the hot electron distribution function, while its shape does not deviate much from that of Maxwellian distribution and the mean energy does not change much during the thermalization process. Based on this observation, axisymmetric JOREK D2 SPI simulations were carried out with additional hot-tail contribution to evaluate their overall impact onto the injection assimilation and penetration. It is found that the hot-tail effect indeed causes enhanced assimilation and shallower penetration, although the overall effect depends on the exact injection configuration, with the slow injection showing negligible hot-tail effect while the fast single non-shattered pellet case shows drastic hot-tail ablation enhancement. For ITER-like SPI parameters, there is no significant deviation in the total assimilation, but some deviation in the injection penetration is observed for the fast injection velocity cases.

Authors: Wu Tingwei 
Published: June 2022

Abstract
The unbalanced mass will cause forced vibration of the pressure vessel when it rotates, and the magnitude of the unbalanced mass is positively correlated with the amplitude of the pressure vessel. Therefore, the study of unbalanced mass is of great significance to the safety of rotating pressure vessels. The influence of form and position tolerances and assembly tolerances on the unbalanced quality of pressure vessel parts is analyzed, and the normal distribution model is used to simulate the tolerance distribution of parts in mass production, and then the total unbalanced mass of the pressure vessel is calculated by the vector synthesis method. Through sensitivity analysis, the parts and key positions that have a greater impact on the total unbalanced mass of the pressure vessel are found, and the geometric tolerances of the parts with high process difficulty are optimized, which provides a theoretical basis for the tolerance optimization design work of the rotating pressure vessel.

Published: June 2022

Abstract
The integration of human factors engineering methods within the medical device design and development process has been highlighted by international standards organizations. Such methods are contributing to the development of safer medical devices, more suitable to users’ needs. Errors during device operation might hamper effective patient diagnosis and treatment, or eventually lead to injury or death. Thus, the designing process of a medical device is indeed crucial to user experience and safety operation. This paper presents a human-centred design analysis of a novel IoT-based screening prototype (iLoF) based on Artificial Intelligence algorithms built-in in a patented-photonics system developed by a deep tech startup. The influence of the design process during the development of the prototype was addressed, based on a human-centred design methodology and considering the device’s application environment. iLoF’s prototype on-field applicability was evaluated considering a single case-study carried out at one of the main hospitals in Portugal through interviews to ten healthcare professionals with high experience in laboratorial testing. A benchmark assessment and a comparison matrix along with the market products are also presented to fully understand the technology state and to find new solutions that can influence iLoF’s product development.

Abstract
To explore the effects of engine jet on overall aircraft aerodynamic performance, an aerodynamic numerical simulation method and the interference effects of aircraft with wing-mounted nacelle were studied. In aspect of numerical simulation, based on isentropic flow relationship and automatic mass-flow matching method, a high-precision / high-efficiency numerical simulation of inlet and exhaust boundary conditions is achieved. The calculation result is in good agreement with the experimental values, which validates the calculation method and boundary condition treatment. Through numerical simulation, it is found that the ejection of engine jet can accelerate the air flow, reduce the lower wing pressure, enhance the upper wing shock wave and increase the pitch down moment. At the same time, the effect of jet brings blowing drag and loses the cruise efficiency. The airflow acceleration caused by the narrow channel composed of engine, wing and pylon may cause strong aerodynamic interference. It can be effectively weakened by adjusting the pylon contraction shape based on the near-field pressure distribution. In this way, the shock in the inner side of the pylon can also be eliminated.

Abstract
The development of the textile industry in Indonesia is rapid. It cause serious environmental problems because the dyes used in the textile industry are synthetic that is azo dyes. Azo dyes are non-biodegradable substances that pollute the environment if not processed. One of the azo dyes that is often used in the textile industry is Methyl Orange. Photodegradation is an inexpensive and environmentally friendly method of removing synthetic dyes. This study will discuss the effect of adding orange peel on the characterization of ZnO and the ability to degrade Methyl Orange. The results of the FTIR spectra showed an absorption in the area of 1430-1455 cm-1 that means the orange peel had been impregnated into ZnO and the more ZnO as added on orange peel, it may reduce the number of -OH and CH groups of the ZnO/OP composite. Based on the results of characterization using XRD, it is known that the addition of orange peel into ZnO did not damage the crystal structure and crystal form. The crystal structure of ZnO/OP formed was wurtzite with a hexagonal shape. The results of the characterization using DR-UV showed that the band gap energy of ZnO/OP was smaller than ZnO and the more ZnO was added, the wider the band gap of energy. ZnO/OP with a variation of 1:25 can degrade Methyl Orange more than ZnO that was 73% in 60 minutes.

Abstract
This study aimed to provide information for people in Banda, Central Maluku, about types and role of mold in lowering the HCN levels in black cassava. It is expected that the availability of alternative choices of quality food ingredients and affordable prices can improve food security and nutrition at the family level. The Identification of mold was performed through 16S rRNA sequence analysis. The analysis of HCN levels in black cassava was conducted using argentometric method. Five mold isolates, namely J1, J2, J3, J4, and J5 were successfully identified from black cassava samples. The mold species were classified into Rhizopus, Aspergillus, Penicillium, Aspergillus flavus and Aspergillus clavatus. The results of the analyses showed that mold and immersion duration played a significant role in lowering the HCN levels in black cassava. In fact, the HCN levels in Manihot aipi decreased significantly from 0.3024% (302.4 mg HCN/kg) to 0.1296 (129.6 mg HCN/kg), 0.135 % (135 mg HCN/kg), 0.162% (162 mg HCN/kg), and 0.1782 (178.2 mg HCN/kg) after 12, 24, 36, and 48-hour immersion, respectively. Similarly, at 12h, 24h, 36h, and 48h fermentation duration, the HCN levels in black cassava were reduced from 0.135% (135 mg HCN/kg) to 0.108% (108 mg HCN/kg), 0.0918% (91.8 mg HCN/kg), and 0.0864% (86.4 mg HCN/kg). The analysis of mold species and HCN levels in black cassava from Manihot aipi Phol. is important because mold species and HCN levels can determine the number of foodborne pathogens that cause many diseases and, in extreme cases, death. The analysis of mold species and HCN levels is also vital to food security. The results of this study can provide insights to the people in Banda regarding the immersion and fermentation duration of Manihot aipiPhol., which is safe for black cassava processing.

Abstract
Agri-Food is another term for the agriculture-based food sector, which is currently one of Indonesia’s main pillars of the national economy. One of the well-known plants for agricultural-based food processing called Agri-Food in Indonesia is Cocoa. Cocoa is one of the plantation commodities that has an essential role in economic activities in Indonesia. Given the critical role of cocoa as a source of the country’s economy, it must guarantee productivity and quality of cocoa and sustainability. To ensure cocoa productivity and quality sustainability, agricultural activities in today’s era can integrate intelligent ubiquitous technology as a framework for obtaining precise production results. What can measure precision production results from three aspects: increasing agricultural land productivity, reducing production costs, and minimizing the environmental impact. This paper discusses the proposed framework with intelligent ubiquitous technology to support precision agri-food that focuses on context-aware systems. The context-aware system in the proposed framework is expected to become a control center in collecting and processing data in real-time to help farmers make the best decisions regarding weather conditions and diseases caused by plants.

Abstract
This study uses LCA analysis to monitor potential damage to eco-efficiency. This approach uses an environmental life cycle assessment (LCA) to detect ecological impacts in natural gas production systems. The study results found that the lowest environmental impact on the production process at PT was seen. X is located on the Ozone layer and Resp. Organics are 4.71E-06 DALY and 3.22E-05 DALY. The highest impact lies in Resp. Inorganics, Fossil fuels, and Climate change. This shows that the drilling system hurts the environment, especially in the climatic conditions of soil, plants, and fossil fuels which continue to decrease. In addition, because the drilling process is carried out using generator power, it causes air pollution that can interfere with the respiratory system (respiratory inorganics).

Published: June 2022

Abstract
Peatlands play an essential role in an ecosystem and generally have three main functions, e.g., a buffer zone in a water system. However, they are vulnerable and susceptible to environmental changes. In response to the increasing demand for habitable space, more peatlands have been converted to productive agricultural land by canal blocking to transform an originally anaerobic environment into an aerobic one. This condition also occurs in peatlands in Sungai Tohor, Tebing Tinggi Island, Kepulauan Meranti Regency. This study sought to determine the groundwater level fluctuations in peatlands after the construction of canal blocks by the Peatland Restoration Agency (BRG). A water level logger was installed at the monitoring well, and the daily groundwater levels were observed for one year. The results showed that the groundwater levels fluctuated from 8.78 m (the lowest) to 9.72 m (the highest), with an average of 9.21 meters. This means that canal blocking might have a sufficient wetting impact, i.e., maintaining the presence of water in the surrounding peatlands.

Helminthiasis is a parasitic worm infection that has imposed economic loss involving some risk factors. This study aimed to investigate the helminthiasis cases in both upland and lowland areas, as well as their risk factors on helminthiasis infection of rabbit farming. A total of 192 rabbit samples was derived from Baturraden and Kalibagor, Banyumas Regency, Central Java Province, Indonesia. The research engaged a survey method with a purposive sampling. Data on the correlation between the areas and helminthiasis incidence were subjected to a chi square analysis. The risk factors were computed in the 2x2 contingency table and analyzed with Odds Ratio. The result showed a significant correlation between the altitude of an area and the helminthiasis incidence (P<0.05). Regarding the host, male rabbit is 1.15 times as risky as the female counterparts to get helminthiasis infection. Meanwhile, the environmental factors, such as the metal floor of the rabbit cage contribute 7.42 times as much risk of helminthiasis infection as that of wooden floor.

Abstract
Infestation of gastrointestinal nematodes to livestock may cause a loss in production performance and under severe condition may lead to death. This study aimed to evaluate the effects of plant extract additions on larval inhibition and mortality of gastrointestinal nematodes. A total of nine articles that comprised of 16 data points were integrated into a database. For each data point, both control and plant extract treatments were specified that included data on number of samples, mean and standard deviation. Effect size of the meta-analysis was based on Hedges’ d with the continuous random effects of DerSimonian-Laird method. Results showed that addition of plant extracts had a strong effect to inhibit larval of gastrointestinal nematodes with a cumulative effect size (95% confidence interval) of 36.6 (30.5-42.7, P<0.001). All papers supported such larval inhibition effect of plant extracts except one paper only. Further, plant extracts increased adult mortality of gastrointestinal nematodes with a cumulative effect size of 73.1 (44.6-101.7, P<0.001). In conclusion, addition of plant extracts that rich in bioactive compounds are effective to control the population of gastrointestinal nematodes. The use of plant extracts for such purpose is favorable since it is environmentally friendly.

Abstract
Health damage caused by pollutants is an important part of environmental externality. Its scientific and accurate evaluation is the basis of environmental policy-making and one of the recent research hotspots. In this paper, the Impact Pathway Approach (IPA) is used to evaluate the externality scale of health damage caused by Particulate Matter (PM) emitted by PPV (Private Passenger Vehicle) of China. Let the public, especially PPV owners, realize that the use of PPV has great health damage to others. Only by making active changes from themselves can reduce the negative externality. The core links of the IPA framework is the Concentration Response Function (CRF) and the determination of the average cost of each health damage observation point. In the end we got a total scale of health damage externality with the mean value of 2678522*104 yuan, in which premature death took the largest part.

Published: June 2022

Abstract
Randomly oriented type I collagen (COL1) fibers in the extracellular matrix are reorganized by biophysical forces into aligned domains extending several millimeters and with varying degrees of fiber alignment. These aligned fibers can transmit traction forces, guide tumor cell migration, facilitate angiogenesis, and influence tissue morphogenesis. To create aligned COL1 domains in microfluidic cell culture models, shear flows have been used to align thin COL1 matrices (<50 µm in height) in a microchannel. However, there has been limited investigation into the role of shear flows in aligning 3D hydrogels (>130 µm). Here, we show that pure shear flows do not induce fiber alignment in 3D atelo COL1 hydrogels, but the simple addition of local extensional flow promotes alignment that is maintained across several millimeters, with a degree of alignment directly related to the extensional strain rate. We further advance experimental capabilities by addressing the practical challenge of accessing a 3D hydrogel formed within a microchannel by introducing a magnetically coupled modular platform that can be released to expose the microengineered hydrogel. We demonstrate the platform’s capability to pattern cells and fabricate multi-layered COL1 matrices using layer-by-layer fabrication and specialized modules. Our approach provides an easy-to-use fabrication method to achieve advanced hydrogel microengineering capabilities that combine fiber alignment with biofabrication capabilities.
