Abstract
To raise the energy cascade use ratio and economic benefit, the multi-energy complementation-based integrated energy system (IES) has been considerably developed in recent years, so studying its internal optimal dispatching strategies will be of great importance. In this study, an optimal dispatching strategy applicable to the operation of typical IES was put forward. First, the classical IES architecture and the operating characteristics of each piece of equipment in it were explored. Second, a mixed-integer programming model with uncertainties was constructed for three energy systems—cooling, heating and power—and each equipment in these systems. In the end, the demonstration park of a major project in China was analyzed using the proposed strategy. The effectiveness of this strategy was verified by the simulation results.

Published: February 2022

Abstract
Microbial-induced calcite precipitation (MICP) can be used to cement soil and produce new biomaterials. The formation of this material is affected by many factors, such as physical, chemical, biological factors, many studies focused on the effect of a single factor on the strength ignoring the synergy between factors. Back-propagation neural network (BPNN) can be used as a multi-factor nonlinear prediction model and an analysis method. 140 MICP grout tests in the literature were summarized to15 factors affecting UCS and act as BPNN input data. At last, five key factors were elected based on weight analysis of well-trained BPNN. On this basis, a simple strength model composed of those factors is established, which can well predict the strength of MICP grouting soil with practical convenience. Key factors and strength prediction models help popularize MICP for engineering applications and optimize grouting experiments.

Published: February 2022

Abstract
Polyurethane (PU) coating can provide physical barrier for metal surface, but the penetration of corrosive ions will affect the long-term corrosion resistance of the coating. In order to improve the corrosion resistance of the coating, it is necessary to modify the coating to reduce the internal defects of the coating and improve the corrosion resistance of the coating. Using mesoporous silica (SiO2) as the carrier to support the corrosion inhibitor 2- mercaptobenzimidazole (MBI), and using the silane coupling agent GPTS as the bridging agent to compound with graphene oxide (GO) to prepare f-GO-MBI @SiO2 composite nano-materials, f-GO-MBI @SiO2 composite nano-materials are added to the polyurethane varnish in different proportions, and the f-GO-MBI @SiO2 modified PU coating is obtained on the surface of carbon steel by spraying method to improve the carbon corrosion resistance of steel substrate. The composition and loading conditions of drug-loaded composite nanomaterials were characterized by fourier infrared spectroscopy (FTIR) and laser particle size analyzer; electrochemical impedance spectroscopy (EIS) and neutral salt spray test were used to study the properties of different coatings corrosion resistance. The results shows that the addition of f-GO-MBI @SiO2 composite nano-materials significantly improves the corrosion resistance of the coating, the low addition amount will reduce the anti-corrosion effect, and the addition of too high can easily lead to agglomeration of composite nano-materials and produce paint film defects. When the addition amount of f-GO-MBI @SiO2 is 5 wt%, the low-frequency impedance of the coating is two orders of magnitude higher than that of the pure polyurethane coating, the corrosion spread width at the neutral salt spray scratches is reduced to 1.5 mm, and the coating has the best corrosion resistance.

Published: February 2022

Abstract
The time-dependent behaviour of AlSi4Mg2 alloy has been investigated with the ICF model. It shows that the apparent viscosity increases with decreasing the shearing time and increasing the resting time, especially at the initial stage. The above variations depend on its microstructure affected by solid volume fraction and shear rate, respectively. It is found that the agglomerating time is about 100 times as long as the deagglomerating time, which agrees with the experiment data.

Abstract
With the rapid popularization of new energy vehicles, users pursue reliable mileage as well as stable and efficient power battery charging and discharging performance, which puts forward higher requirements for on-board battery management system (BMS). Realizing online update of battery model parameters and accurate estimation of charged state has also become one of the key technical problems in the field of new energy vehicles at present. In this paper, based on the second-order resistor-capacitor (RC) equivalent circuit model, multiple parameters in the voltage relaxation stage were obtained through the curve relationship between open circuit voltage and state of charge, and the fast time-varying parameters were converted into parameters of different step sizes. An estimation model of state of charge based on fixed step Kalman Filtering algorithm was built by Simulink to realize online estimation of battery parameters and state of charge estimation.

Abstract
A key component of the differential diagnosis of isolated hyperbilirubinemia (HB) is distinguishing between hemolytic and non-hemolytic types. Routine hemolysis screening markers have unsatisfactory sensitivity and specificity. Erythrocyte (RBC) lifespan shortening, the gold standard marker of hemolysis, is seldomly measured due to the cumbersome and protracted nature of standard methods. A new Levitt’s CO breath test method may enable simple, rapid RBC lifespan measurement. In this pilot prospective diagnostic study, Levitt’s CO breath test was evaluated to discriminate hemolytic from non-hemolytic HB in adults. One hundred and thirty eligible non-smoking adult patients who were aged 18 or older, referred for chronic (>6 months) isolated HB or had a known diagnosis of isolated HB of a rare cause, were recruited, including 77 with non-hemolytic HB and 53 with hemolytic HB. ROC curve analysis was applied to determine the optimal cutoff for discriminating between hemolytic and non-hemolytic HB, and the performance was calculated. Results showed that the mean RBC lifespan in non-hemolytic HB (93 ± 26 d) was reduced (p = 0.001 vs. normal reference value of 126 d), but longer than that in hemolytic HB (36 ± 17 d; p = 0.001). RBC lifespans did not differ significantly between 26 patients with simple hemolytic HB (32 ± 14 d) and 27 patients with a Gilbert syndrome comorbidity (40 ± 18 d). ROC curve analysis revealed an optimal lifespan cutoff for discriminating between hemolytic and non-hemolytic HB of 60 d (AUC = 0.982), with a diagnostic accuracy of 95.4%, 94.3% sensitivity and 96.1% specificity respectively. These results indicate that Levitt’s CO breath test seems to be very sensitive and specific for detecting hemolysis in adult patients with chronic isolated HB, and could enable simple, rapid, and reliable differential diagnosis of isolated HB. A large-scale validation study of the method is warranted.

Abstract
The possible risk of yield losses due to drought stress could threaten rice production and national food security. One way to deal with drought limitations is by developing drought- tolerant varieties using gamma-ray irradiation. This research aimed to get the optimal dose of gamma-ray radiation to create an M7 generation of Mentik Wangi variety that is drought tolerant. Field experiments were conducted from December 2020 to March 2021 at the Screen House of the Faculty of Agriculture, Universitas Sebelas Maret, Surakarta, the Laboratory of Soil Physics, and the Laboratory of Plant Production Management, Faculty of Agriculture, Universitas Gadjah Mada. This study has carried out using a Randomized Complete Block Design with two factors. The first factor is gamma-ray irradiation dose (0gy. 100gy, 200gy, 300gy), and the second factor is drought stress treatment (without drought stress and drought stress in the flowering stage) with three replications. The results showed no interaction between gamma-ray irradiation dose and drought stress on all observed variables except plant dry matter. Drought stress in the flowering stage increased the percentage of unfilled grain, reducing the harvest index and grain weight significantly by 40.9%. Gamma-ray irradiation in a range of 100 to 300 gy did not affect panicle numbers and length, also the percentage of unfilled grain, but reduced the number of grains per panicle, thereby reducing the harvest index and grain weight 45.0% compared to those without irradiation.

Published: February 2022

AbstractThe Mt. Merapi eruption in 2010 devastated the economic and ecological conditions in the affected areas. However, the volcanic material from the eruption has a positive impact on land rejuvenation, due to the addition of weatherable minerals which are rich in nutrients for plants. This study aims to re-evaluate the land suitability of the areas affected by the 2010 Merapi eruption for fruit crops. The research was conducted at 7 areas (Kaliadem, Kinahrejo, Jambu, Petung, Ngepringan, Pager Jurang, and Gadingan) based on the volcanic material distribution map. The selected commodities and will be developed are based on the existence of fruits that grew in this area before the eruption, namely jackfruit, avocado, banana, and arabica coffee. The results of this study indicate that land that has been affected by the Merapi eruption is classified as unsuitable for the proposed commodity with the main limiting factor being low nutrient and water retention, in addition to the upper slope area there are additional slope limiting factors. However, this area still has the opportunity to be developed because it is rich in "weatherable minerals" which can be a source of nutrients for plants. Amendment materials that can increase nutrient and water retention and accelerate the release of nutrients from rocks need to be provided, such as compost rich in organic acids.
