Abstract
In recent years, the ultrasonic technique is being developed at a pretty faster speed, whose assisting tactic has been applied in the electronic packaging field. What we need is to determine the mechanisms of ultrasonic treatments on electronic packaging fillers. In this paper, Pb-based alloy is typically chosen as the filler metal, in this paper, it is found that the flowability of which can be improved under ultrasonic vibration. Also, ultrasonic degassing efficiency is greatly promoted, with the best parameter for degassing that ultrasonic power and duration time of 1000W and 60s, a molten alloy’s treating temperature of 340°C. The assistance of ultrasonic is deeply explained from the thermodynamic aspect. Understanding of the atomic level interactions of liquid Pb atoms and vacuum is crucial, so we make an ultrasonic-assisted molecular dynamic simulation of melting Pb to room temperature to 330°C in 10ps, and the diffusion behavior of Pb atom under periodic vibration is revealed.

Published: February 2022

Abstract
Due to the different sizes and heights of ships docked at the port and the rise and fall of water at the harbor, there are many problems in providing electricity to ships berthing at the port [1]. The shore power cable lifting device is adaptable to the cable connection under different environments, mainly consisting of a multi-stage telescopic hydraulic arm [2], a cable drum, a luffing mechanism, and a slewing mechanism. In the process of cable lifting, the cooperative control of multiple working mechanisms is related to the cable connection precision, as well as the safety. Compared with the traditional control of the circuit, PLC control can ensure higher accuracy and safety, and improve the automation level and convenience of shore power connection.
PCEs containing C5 and C6 based PEO side chains: A comparison on the synthesized polymers and the resulting dispersing effectivenesss
Authors: Ng Serina , Feng Ke , Liu Zhaoyang 
Published: February 2022

Abstract
The reactivity of C5 and C6 based PEO macromonomers in the synthesis of PCE superplasticizers, followed by the dispersing abilities of such PCEs on cement pastes were analysed and compared in this study. It was found that free radical compolymerisation of C5 macromonomers and acrylic acid (AA) produced PCEs with less controlled block compolymers characteristics, which were highly sensitive to reaction conditions such as the rate of polymer additions, etc. This can be attributed to the difference in reactivity constants of the monomers, where AA was highly reactive. The orderness became more dominant when the temperature of synthesis was suitably controlled. The ease in adapting the molecular architecture of C6 based PCEs as compared to C5 based PCEs enabled better prediction of cement dispersing ability, as confirmed by the slump flow tests performed. It was thus shown through this study that using C6 macromonmers, PCE with tailormade acrhitecture could be developed easier than with C5 macromonomers, potentially to adapt to different types of cement on the market.

Abstract
The 5A06 Al-Mg alloy is a soft material, and the phenomenon of knife sticking is extremely serious during cutting, likewise, it is easy to generate build-up edges. Therefore, it is difficult to acquire good surface quality in turning. For this purpose, the ultrasonic theory and cutting theory are fully combined in this study, and the machining mechanism of conventional turning (CT) is changed by applying ultrasonic vibration (UV) to the cutting tool, so as to build up the machining results. The turning experiments of 5A06 Al-Mg alloy with or without UV are carried out under different process parameters, and through which the effects of ultrasonic amplitude (UA), feed rate (FR), cutting depth (CD) and cutting speed (CS) on the surface roughness of machined workpiece are investigated and analyzed. The consequences show that the process parameters have a different degree of effect on surface roughness. And there are special process parameters suitable for UV assisted turning (UAT), under which the processing results of UAT is obviously better than that of CT. In addition, it is found that by contrast experiment of surface topography under ideal process parameters built-up edges, surface scratches and other phenomena are not easy to arise in UAT to obtain the better surface topography than CT.
Phospholipid and menthol based nanovesicle impregnated transdermal patch for nutraceutical delivery to diminish folate and iron deficiency

Published: February 2022

Abstract
Adequate micronutrient availability is particularly important in women, children and infants. Micronutrient deficiencies are the major cause of maternal and neonatal morbidity. To overcome this, WHO recommends the use of folic acid and iron supplements for reducing anaemia and improving the health of the mother and infants. Oral intake of supplements for nutritional deficiencies are associated with gastric irritation, nausea, constipation and non-patient compliance due to associated taste. In case of absorption deficiency nutrients administered orally pass-through digestive tract unabsorbed. In the present study, we propose transdermal delivery of nutraceuticals to avoid the limitations associated with oral intake. Transdermal delivery has limited use because of the closely packed barrier of the stratum corneum that limits the permeability of molecules across skin. Here, we have used biomimetic nanovesicles impregnated in transdermal patches for delivery of folic acid and iron. Nanovesicles are prepared using an abundant component of cell membrane, phosphatidyl choline and a permeation enhancer. Further these nanovesicles are impregnated onto polyacrylate based transdermal patch. In vitro studies have shown the ability of nanovesicles to fluidise skin lipids and penetrate into deeper skin. In vivo application of transdermal patches gradually increased the systemic concentration of nutraceuticals. Post application of the patch, five-fold increase in plasma folic acid concentration and 1.5-fold increase in plasma iron concertation was achieved in 6 h. Developed nanovesicles were compatible with keratinocytes and fibroblasts as tested in vitro and have the potential to enhance the cellular uptake of molecules. Skin irritation studies on human volunteers have confirmed the safety of nutraceutical loaded nanovesicles. Thus, the developed nutraceutical loaded transdermal patches provide a potential, easy to use platform for micronutrient delivery in infants and mothers.
Ribbon operators in the generalized Kitaev quantum double model based on Hopf algebras
Authors: Yan Bowen , Chen Penghua , Cui Shawn X 
Published: February 2022

Abstract
Kitaev’s quantum double model is a family of exactly solvable lattice models that realize two dimensional topological phases of matter. The model was originally based on finite groups, and was later generalized to semi-simple Hopf algebras. We rigorously define and study ribbon operators in the generalized quantum double model. These ribbon operators are important tools to understand quasi-particle excitations. It turns out that there are some subtleties in defining the operators in contrast to what one would naively think of. In particular, one has to distinguish two classes of ribbons which we call locally clockwise and locally counterclockwise ribbons. Moreover, we point out that the issue already exists in the original model based on finite non-abelian groups, but it seems to not have been noticed in the literature. We show how certain common properties would fail even in the original model if we were not to distinguish these two classes of ribbons. Perhaps not surprisingly, under the new definitions ribbon operators satisfy all properties that are expected. For instance, they create quasi-particle excitations only at the end of the ribbon, and the types of the quasi-particles correspond to irreducible representations of the Drinfeld double of the input Hopf algebra. However, the proofs of these properties are much more complicated than those in the case of finite groups. This is partly due to the complications in dealing with general Hopf algebras rather than group algebras.

Published: February 2022

Abstract
Drought stress is one of the most common abiotic stress in agriculture. The use of antitranspirant agents to reduce the effect of drought stress on crops has been considered as a potential method. The application of chitosan as an antitranspirant agent has been reported to be effective in several crops. This study was aimed to analyze the effect of chitosan foliar application for maintaining the growth of lettuce under drought conditions. Three concentrations of chitosan (0.2 g/L; 0.4 g/L; 0.6 g/L) were tested in this study. The parameter observed were the height of the lettuce, number of leaves, leaf length and the width, root length, as well as fresh and dry weight. The drought condition without chitosan application reduced the growth of lettuce in all parameters. Chitosan application at 0.2 g/L was able to reduce the effect of drought stress and maintain the growth of lettuce. However, higher chitosan concentration applications (0.4 g/L and 0.6 g/L) were observed to reduce the growth of lettuce. Based on this study, chitosan was reported to reduce the effect of drought stress in lettuce. As chitosan affects the transpiration process by stomatal closure, a higher concentration of chitosan may also affect the photosynthesis process leading to growth inhibition.

Abstract
The pre-cooking process carried out in the fish canning industry still uses the method of steaming on the stove. The difference in the capacity of the pre-cooking and sterilization processes causes a long holding time, which has the potential for microorganism contamination and low productivity. Research on the prototype of an integrated semi-automatic mini exhausting unit with a capacity of up to 300 cans of 115 mL using a hot steam source from a sterilization retort has to increase production capacity and efficiency. The size mini exhausting has a size of 4 meters x 1 meter and is made of 304 stainless material. It has 3 parts, namely the preparation part, the heating part, and the draining section. The drain part was located on the outside of the mini exhausting box. The draining part has a pan that can be rotated 150 degrees to remove the fish liquid in the can before the next process. The results of the exhausting room temperature reached 90°C within 8 minutes at an autoclave pressure of 0.8 bar. Fish meat reaches a temperature of 80 degrees after heating in the 12th minute. In the mini exhausting system, production capacity can be increased up to 8 times, with 25% electrical energy efficiency.

Abstract
The objectives of the study were to determine the antibiotic resistance of Lactic Acid Bacteria (LAB) isolated from kefir made from Etawah goat milk. A total of 25 isolates were isolated from etawah goat milk, yogurt and kefir. LAB isolates were resistant to Ceftazidime (Caz, 100%), Ceftriaxone (Cro, 100%), Clindamycin (Da, 100%), Lincomycin (Li, 100%), Rifampicin (Rd, 100%) and Tobramycin (Tob, 100%). The bacteria were susceptible to Sulphamethoxazole-Trimethoprim (Sxt, 60%) and Tetracycline (Te, 40%). The percentage of antibiotic resistance of LAB was found to be in the range between 40 to 100%. The presence of antibiotic resistance in good bacteria may introduce the horizontal genetic transfer to bad bacteria which has the potential to disrupt human health.

Abstract
The agricultural sector is the leading sector of the Banyuwangi Regency. However, the contribution of the farming sector to the Gross Regional Domestic Product (GRDP) of Banyuwangi Regency continues to decline by up to 30% in 2019. The decline in the agricultural sector’s contribution to the GRDP of Banyuwangi Regency is partly due to the declining interest of the younger generation in the farming industry so that the regeneration of agricultural, human resources continues very slow. This study aims to analyze the strategy of developing the younger generation’s interest in the Banyuwangi Regency. The analytical method used is Interpretative Structural Modeling (ISM) to produce designs according to conditions. The results of the analysis show that the agricultural preference of the younger generation is digital-based agricultural cultivation. The strategy that needs to be developed is local government policy. Local Government policy is a critical factor in developing young people’s interest in the agricultural sector in Banyuwangi Regency.

Abstract
Accurate electricity consumption forecasting can improve the efficiency of grid dispatching and effectively guarantee the stable operation of the power system. Electricity consumption forecasting is important for the analysis of customer-side electricity consumption behavior, but the instability of electricity consumption sequences poses difficulties for forecasting. Therefore, an improved combination of integrated empirical modal decomposition (EMD) and long short-term memory network (LSTM) is proposed for customer-side electricity consumption forecasting. This paper starts from the idea of blind source separation and independent prediction, and firstly decomposes the original electricity consumption data into several inherent mode functions (IMFs) with different frequencies and amplitudes by empirical modal decomposition (EMD), and then uses LSTM to extract features and make temporal prediction for each IMF component one by one with machine learning intelligent algorithm., and finally obtains end-user-side short-term electricity consumption prediction results by accumulating multiple target prediction results. Compared with direct forecasting, the proposed EMD-LSTM independent forecasting model is able to identify the characteristics of each frequency component of electricity consumption data, and its error is reduced by about 15% on average, thus achieving the goal of improving the accuracy of load forecasting in short-term electricity consumption forecasting scenarios.

AbstractWith the development of power grid technology and the widespread application of gas insulator switchgear (GIS) equipment, the power supply reliability of the power system has been greatly improved, but the problem of partial discharge (PD) faults in GIS has always been prominent, seriously affecting the safe and stable operation of the power grid. How to quickly determine the type and cause of GIS discharge is the key to online PD detection. In this paper, in order to deal with the very complicated data processing of ultra-high frequency (UHF) PD, the time-consuming and low efficiency of manually judging the type of PD, a classification model of UHF PD system based on deep confidence network (DBN) is established and an automatic classification method for UHF PD based on improved DBN is proposed; the activation function Sigmoid is improved to effectively prevent the occurrence of the gradient disappearance problem; the optimized DBN parameters are used to train and classify data of different PD types. The classification accuracy rate of the test results reached 96.7%, realizing the rapid classification evaluation of UHF PD types.
