Authors: Linggarjati Jimmy 
Published: March 2022

Abstract
Measurement and data-logging of temperature are important in industrial application. This paper discusses the implementation of monitoring temperature of cylinder hydraulic of a heavy equipment such as excavator in the field. For monitoring the temperatures, DS18b20 sensors are used to sense the hydraulic arms in the excavator. Due to sensing moving parts such as hydraulic arms, a WiFi technology is used to transmit temperature’s data to a browser. The ESP-NOW technology from Espressif ESP32 is chosen to minimize the electrical energy drained from the Lipo’s battery. Data-logging is done in a browser environment, by using javascript, websockets, css, and html technologies. The result shows that the usage of ESP32 in monitoring the temperatures, can be used in the real-time mode for the monitoring of excavator operations. And the 20000mAh battery-based system can last for approximately a month by using ESP-NOW technology from the Espressif.

Abstract
Solar dryer is typically used for agricultural purposes in Indonesia. There are many economically important crops requiring storage or drying under particular environmental conditions such as temperature and humidity. High temperatures inside solar dryer prevents the growth of microorganism, and quickly reduce moisture content from the substance. A hybrid solar dryer is generally considered to provide the most optimum solution, however solar panels may be expensive and they still only provide heat or energy in the daytime. Hence, we propose here a new kind of hybrid solar dryer for 24/7 optimum conditions for crops - enabled by recent advances in energy technologies as well as Industry 4.0. This study aims to create an efficient, affordable and a self-sufficient intelligent energy system that will be applied to agriculture for storage or drying purposes by measuring the energy needs for the optimal drying system. Therefore, it is crucial to estimate and assess the critical energy needs for such new systems in order to optimize and design such smart solar dryer (SSD) system especially for Indonesia’s agricultural needs. We use design experience of our industry partner (PT Impack Pratama Industri, Indonesia) who has been working extensively on such solar dryer dome (SDD) based on polycarbonate material (only solar irradiation, no other technologies) and theoretical framework based on first principles in thermodynamics to estimate and assess critical energy needs for such dome with all the smart technologies. The calculation was performed based on Mollier diagram and the result still a rough estimation of energy required.

Published: March 2022

Abstract
Taro is one of the tubers rich in starch which is prospectively improved for its functional properties. In this work, the cooling treatment subjected to the autoclaved taro flour on resistant starch formation and pasting behaviour were evaluated. The flours were autoclaved at 121°C for 30 minutes followed by cooling at different temperatures (25, 4, and -20°C) and repeated twice cycles. Among the cooling treatments, the 4°C had the highest RS (13.11%) compared to 25°C and 4°C which were 13.02% and 12.76% respectively. The autoclaved-cooled treatment altered the microstructure of starch granules showing fracture morphology and irregular shape. The starch morphology treated by autoclaving-cooling at the lowest temperature exhibited a slightly rougher and more wrinkled than other cooling temperatures. Moreover, repeated autoclaving-treatment lowered the pasting temperature. Other than the cooled flour at 25°C, the pasting parameters of the treated flours (peak, final viscosity, and setback) were higher than the untreated flour.

Authors: Gipolan I G , Tabinas R J 
Published: March 2022

AbstractCorning is a preservation method that involves soaking the raw material with salt to add flavor and extend shelf life. Milkfish, which is abundant in the Philippines, was developed into a corned product incorporated with a by-product of jackfruit which is the rags. The levels of salt and jackfruit rags were optimized using a 3 by 3 full factorial design with three (3) levels of jackfruit rags (15 g, 20 g, and 25 g) and salt (7.5 g, 15 g and 22.5 g). The result of sensory evaluation revealed that color, odor, taste, and general acceptability were significantly affected by salt, while texture and general acceptability were significantly affected by varying levels of jackfruit rags. The acceptability for all the attributes was moving towards high jackfruit rags and middle level of salt. Treatment 8 consisting of 15 grams salt and 25 grams jackfruit rags with a total cost of 1.74 USD/250 grams fell on the optimum region and was preferred by 55% of the consumers over the commercial brand. This formulation is light brown, moderately salty, slightly tender, has a well-blended fishy odor & jackfruit, liked very much by the panelist, and has a pH of 5.79.

Published: March 2022

Abstract
Aluminum and its alloys having lots of advantageous properties are among the most-used metallic materials. So, it is of immense importance to find suitable processes and methods leading to high-quality purified Al melt. In this regard, there are numerous challenges in achieving high purity Al melts, such as its propensity to react with air, oxygen, and water vapor, the presence of a variety of oxide, non-oxide, and solid particle inclusions that lead to the production of pores, cracks, pinholes, and dross, finally adversely influencing the overall quality of the product. The main methods of melt refining are fluxing, floatation, and filtration, but more sophisticated methods have also emerged. The best method for purification can be chosen based on the type of impurities and the desired level of purification. With the industrial development, the need to establish more cost-effective and simpler methods has increased, and in addition, methods should be considered for recycling large volumes of scarp Al parts that contain more impurities. Moreover, achieving high purity melt is also a vital issue for use in specific applications. The present article has been written to discuss the above issues and focus on the study of various methods of aluminum purification.
Influence of corona discharge on the hydrophobic behaviour of nano/micro filler based silicone rubber insulators
Authors: Tahir M Hijaaj , Arshad A , Manzoor Habib Ullah 
Published: March 2022

Abstract
Silicone rubber is one of the most used outdoor insulation materials in the last few decades due to its improved performance in contaminated and humid conditions. The improved performance of silicone rubber insulators is due to their hydrophobic nature, however, the organic nature of silicone molecules makes them vulnerable to ageing and degradation. This paper aims at investigating the loss and recovery of hydrophobicity of four different silicone rubber micro/nanocomposites exposed to corona discharge. The samples were exposed to corona discharge generated by pin-plate electrode configuration under AC stress. A series of tests were performed to observe the impact of different electrode-sample gaps and for various periods of corona exposure. The hydrophobicity of samples was measured pre and post corona exposures at various intervals up to 72 h. This time could confirm the hydrophobicity recovery process. Numerical simulations were also performed in COMSOL Multiphysics to investigate the electric fields along the sample surface at different electrode gaps. Experimental results showed that samples recovery time was proportional to the duration of exposure to corona discharge and inversely proportional to the electrode-sample gap. Among all, samples with 2.5% nano-silica as additive showed better hydrophobicity recovery. Simulation results showed that an increase in electrode gap resulted in decreased electric field intensity, hence supporting the experimental outcomes.

Published: March 2022

Abstract
In this work, we demonstrate a flexible multi-pin plasma generator with movable electrodes, which can change the shape of the electrode array freely, and then provide a large-area uniform plasma for the treatment of surfaces of different shapes. Discharge characteristics including U–I waveforms and discharge images and sterilization performance under three different electrode configurations (flat–flat, flat–curve, curve–curve) are investigated. Very similar results are acquired between the flat–flat configuration and the curve–curve configuration, which is much better than that under flat–curve configuration. This flexible multi-pin plasma generator offers a simple method to treat different irregularly shaped surfaces uniformly with a single device. Moreover, this device provides a foundation for developing a self-adaption large-scale uniform plasma generator by further introducing automatic adjustment of the position of every electrode driven by motors with discharge current feedback in the following study. Thus it will promote the applications of atmospheric-pressure cold plasmas significantly.

ABSTRACTTaste perception is affected by various environmental factors. In the present study, we investigated the effects of visual and aromatic stimulations on stress responses and taste perception. Fourteen young healthy participants were assessed for stress levels and taste intensities under 5 different conditions: normal (no stimuli), watching an action scene, watching a forest scene, sniffing a rosemary aroma, and sniffing a lavender aroma. Compared to participants under the action scene condition, participants under the forest scene or under the rosemary aroma condition showed significantly lower stress levels. Furthermore, the forest scene condition significantly increased the saltiness intensity, whereas the rosemary aroma condition significantly increased the bitterness intensity. A positive or negative correlation was observed between the stress level and taste intensity of sourness and saltiness, respectively. These findings indicate that visual image and aroma have the potential to change taste perception as well as modulate stress conditions.

Published: March 2022

Abstract
With the advances in sequencing technologies, a huge amount of biological data is extracted nowadays. Analyzing this amount of data is beyond the ability of human beings, creating a splendid opportunity for machine learning methods to grow. The methods, however, are practical only when the sequences are converted into feature vectors. Many tools target this task including iLearnPlus, a Python-based tool which supports a rich set of features. In this paper, we propose a holistic tool that extracts features from biological sequences (i.e. DNA, RNA and Protein). These features are the inputs to machine learning models that predict properties, structures or functions of the input sequences. Our tool not only supports all features in iLearnPlus but also 30 additional features which exist in the literature. Moreover, our tool is based on R language which makes an alternative for bioinformaticians to transform sequences into feature vectors. We have compared the conversion time of our tool with that of iLearnPlus: we transform the sequences much faster. We convert small nucleotides by a median of 2.8X faster, while we outperform iLearnPlus by a median of 6.3X for large sequences. Finally, in amino acids, our tool achieves a median speedup of 23.9X.

Published: March 2022

AbstractSpermatogenic regeneration is key for male fertility and relies on activities of an undifferentiated spermatogonial population. Here, a high-throughput approach with primary cultures of mouse spermatogonia was devised to rapidly predict alterations in functional capacity. Combining the platform with a large-scale RNAi screen of transcription factors, we generated a repository of new information from which pathway analysis was able to predict candidate molecular networks regulating regenerative functions. Extending from this database, the SRCAP-CREBBP/EP300 (Snf2-related CREBBP activator protein-CREB binding protein/E1A binding protein P300) complex was found to mediate differential levels of histone acetylation between stem cell and progenitor spermatogonia to influence expression of key self-renewal genes including the previously undescribed testis-specific transcription factor ZSCAN2 (zinc finger and SCAN domain containing 2). Single cell RNA sequencing analysis revealed that ZSCAN2 deficiency alters key cellular processes in undifferentiated spermatogonia such as translation, chromatin modification, and ubiquitination. In Zscan2 knockout mice, while spermatogenesis was moderately impacted during steady state, regeneration after cytotoxic insult was significantly impaired. Altogether, these findings have validated the utility of our high-throughput screening approach and have generated a transcription factor database that can be utilized for uncovering novel mechanisms governing spermatogonial functions.

Published: March 2022

AbstractWilms’ tumor 1 (Wt1) encodes a zinc finger nuclear transcription factor which is mutated in 15–20% of Wilms’ tumor, a pediatric kidney tumor. Wt1 has been found to be involved in the development of many organs. In gonads, Wt1 is expressed in genital ridge somatic cells before sex determination, and its expression is maintained in Sertoli cells and granulosa cells after sex determination. It has been demonstrated that Wt1 is required for the survival of the genital ridge cells. Homozygous mutation of Wt1 causes gonad agenesis. Recent studies find that Wt1 plays important roles in lineage specification and maintenance of gonad somatic cells. In this review, we will summarize the recent research works about Wt1 in gonadal somatic cell differentiation.

Published: March 2022

AbstractAnalysing EEG complexity could provide insight into neural connectivity underlying attention-deficit/hyperactivity disorder symptoms. EEG complexity was calculated through multiscale entropy and compared between adults with attention-deficit/hyperactivity disorder and their peers during resting and go/nogo task states. Multiscale entropy change from the resting state to the task state was also examined as an index of the brain’s ability to change from a resting to an active state. Thirty unmedicated adults with attention-deficit/hyperactivity disorder were compared with 30 match-paired healthy peers on the multiscale entropy in the resting and task states as well as their multiscale entropy change. Results showed differences in multiscale entropy between individuals with attention-deficit/hyperactivity disorder and their peers during the resting state as well as the task state. The multiscale entropy measured from the comparison group was larger than that from the attention-deficit/hyperactivity disorder group in the resting state, whereas the reverse pattern was found during the task state. Our most robust finding showed that the multiscale entropy change from individuals with attention-deficit/hyperactivity disorder was smaller than that from their peers, specifically at frontal sites. Interestingly, individuals without attention-deficit/hyperactivity disorder performed better with decreasing multiscale entropy changes, demonstrating higher accuracy, faster reaction time and less variability in their reaction times. These data suggest that multiscale entropy could not only provide insight into neural connectivity differences between adults with attention-deficit/hyperactivity disorder and their peers but also into their behavioural performance.
