Authors: Yan Rong , Dai Limei , Kang Hongling 
Published: January 2021

Abstract
This paper mainly measured the adsorption of corn protein on corn starch, studied the changes of protein adsorption under different conditions, and discussed the adsorption mechanism of corn starch and protein. The results showed that when the adsorption time was 1h, the amount of adsorbed protein was the largest. Heating will increase the adsorption capacity; In the range of pH3-9, with the increase of pH value, the adsorption amount of protein firstly increases and then decreases, and the adsorption amount is the largest when pH value is about 6. Adsorption decreases with the increase of ionic strength. The addition of acid pulp can reduce the occurrence of protein adsorption, and the amount of protein adsorption is the least when the acid pulp is added to 50%. Increasing the number of pores and pore size on the surface of starch particles can increase protein adsorption. The adsorption isotherm of corn protein used in this experiment on corn starch granules is S-type, belonging to type II adsorption isotherm.
Research on Spiral Bevel Gear Detection Based on Environmental Tooth Surface Error Correction Method
Authors: Ge Xiaolin 
Published: January 2021

Abstract
This paper studies the influence of the machine tool adjustment parameter error on the tooth surface error of the spiral bevel gear wheel processed by the double helix method. Based on the gear meshing principle, MATLAB software was used to establish the error tooth surface equation, and the analytical formula of the discrete point error of the tooth surface containing the machine tool adjustment parameter errors was derived. The topological map of the concave and convex tooth surface errors corresponding to the machine tool adjustment parameter errors was obtained and analyzed. The mapping relationship between machine tool adjustment parameter errors and tooth surface errors is determined, and the adjustment parameters that have a greater influence on the tooth surface errors are determined. With the help of the approximate expression of the topological diagram of the tooth surface error by the second-order surface, the influence weight of the machine tool adjustment parameter error on the tooth surface error is obtained. Based on the tooth surface error and the two-tooth surface error sensitive matrices, a tooth surface error correction model was established. The least square method of the generalized inverse matrix was used to transcend the equations to obtain the correction amount of the machine tool adjustment parameters. Finally, an example is used to verify the correction effect of the error tooth surface. The results show that the error of the tooth surface on the concave and convex sides after the correction is greatly reduced.

Published: January 2021

Abstract
Comparative analysis of limestone sludge in recycled water and desulfurization limestone is made in the chemical composition, reaction activity, crystallization properties and pH of Slurry. The results show that the limestone sludge in recycled water is possible to be used as a desulfurizer. Due to the large amount of impurities and lower reactivity of limestone sludge, the overall performance index values of limestone sludge are lower than that of desulphurization limestone. If it wants to be used as a desulfurizer, the further research on the using conditions of recycled water limestone sludge in desulfurization system and the possible impact of the reuse of desulfurization system on the stable operation of the system are needed.

Abstract
Antibiotics are widely used in animal husbandry as veterinary drugs and feed additives, resulting in a large amount of antibiotic residues in animal feces. In order to achieve harmless and resourceful utilization of livestock manure, anaerobic fermentation is the most extensive treatment method in the world. It briefly introduces the residues of antibiotics such as oxytetracycline, chlortetracycline, and tetracycline, which are currently used the amount. The effects of antibiotics on anaerobic fermentation gas production performance and research progress are discussed in recent years. A large number of results indicate that the influence of antibiotics on the fermentation system mainly occurs in the initial stage of fermentation. There are mainly H2 / CH4 reduction path ways, acetic acid fermentation pathways and methyl conversion pathways. Methanogenic and acidogenic microorganisms are closely related to these pathways in the fermentation system. And the effects of antibiotics on the methanogenic microorganisms in the fermentation system are described. It is suggested that the future research direction should further study the effect of antibiotics on antibiotic resistance genes in livestock and poultry manure.

The energy future of Saudi Arabia is not batteries and photovoltaic solar panels
Authors: Boretti A , Castelletto S , Al-Kouz W , Nayfeh J 
Published: January 2021

Abstract
Recently, North European academics claimed that “Saudi Arabia can accomplish a 100% renewable energy by 2040 that is overwhelmed by PV single-axis following and battery storage”. They moreover say “Battery capacity contributed up to 30% of the full power request in 2040 and the commitment increments to 48% by 2050”. Based on geology, climate conditions, and resources of Saudi Arabia, it is clarified as batteries and photovoltaic solar panels are not the best choice for the country’s energy sector. To cover all the energy supply of Saudi Arabia by solar photovoltaic, plus battery capacity to compensate for the solar energy fluctuations, and unpredictability, is not convenient, for both the economy and the environment. Superior results for the environment and the economy may be accomplished by valorising the fossil fuel assets, through the development of high-efficiency plants such as the combined cycle gas turbine plants of Qurayyah, the advancement of innovations for the generation of clean power, counting oxyfuel combustion and carbon capture and storage, and also developing nuclear energy. The development of nuclear power plants may be more advantageous to the economy and the environment than photovoltaic and batteries. Concerning solar energy, parabolic trough solar thermal power plants also along the coast have advantages versus solar photovoltaic, as thermal energy storage could provide dispatchability. Additionally, a centralized power plant works better than many rooftops photovoltaic that will be likely covered by sand, rusted, or cracked after a few years.

Published: January 2021

Abstract
Electronic waste (e-waste) has been proven to pollute the soil, air, and groundwater significantly. Aside from the physical effect of coming in contact with pollution, the radioecological impact of the pollution may be dangerous either directly or indirectly to persons living at the source of pollution. In this study, the lead (Pb) pollution from e-waste was used to calculate several organisms’ radioecological parameter. It is was observed that there was a moderate reduction in the number of plants with leaves (22%), a major reduction in cumulative stem growth (43% the control value), a severe increase in the number of chlorophyll mutations, severe changes in leaf colour (4.9-fold), and a major increase in mortality for all organism. It is recommended that landfill areas where e-wastes are dumped be excavated 9 m depth as a corrective measure to reduce the negative outcome on landfill workers.

Abstract
As an important equipment in the construction field, cuplock scaffold plays an important role in the construction process. As a scaffold connecting member, cuplock joint is of great importance. In order to explore the rotational stiffness non-linear characteristics changing features of different structural forms of cuplock joint in different tightening torque condition under different condition of load, ANSYS is used to establish four kinds of cuplock joint models with different forces to simulate the real force situation. By setting the different applying condition, that is, the cuplock is loaded at a certain distance from the cuplock joint in a certain direction until the cuplock is damaged, and considering the gap between the cross bar joint and the vertical bar, the differences in the influence of the structural form and tightening torque on the rotation stiffness of the cuplock under different load conditions are compared. It is significantly important to improve the accuracy of calculating bearing capacity and stability of the cuplock steel tubular scaffolding.

Authors: Yiwei Li , Xiuyong Liu , Xiaohui Zhai , Taochun Yang 
Published: January 2021

Abstract
In order to study the mechanical behaviour of the cross-slanted corrugated steel plate shear wall, the performance of the wall under one-way loading and low cycle loading was analyzed using the finite element analysis software ABAQUS. And the performance compared between flat steel plate shear wall (FSPW), single inclined corrugated steel plate shear wall (SCSPW) and horizontal corrugated steel plate shear wall (CSPW) was studied. The results show that the effect of self buckling of the models of cross-slanted corrugated steel plate shear wall (CCSPW) is significant due to the interaction of two layers of corrugated steel plates. The yield bearing capacity, ultimate bearing capacity and out of plane deformation of CCSPW are better than those of CSPW, SCSPW and FSPW with the same thickness. The yield bearing capacity is 1.09 times of the same thickness of CSPW, 1.22 times of the same thickness of SCSPW. The ultimate bearing capacity is 1.25 times of the same thickness of CSPW, 1.57 times of SCSPW. And the out of plane deformation is 1/3 of the same thickness of CSPW. Under the low cycle loading, the hysteretic curve of CCSPW is shuttle shaped, full and stable. And there is no obvious “pinching” phenomenon in the whole loading process. Compared with CSPW, SCSPW and FSPW, The CCSPW has better hysteretic performance and energy consumption capacity.

Laser sintering of copper conductive traces on primer pre-treated additive manufactured 3D surfaces
Authors: Olsen Ejvind , Overmeyer Ludger 
Published: January 2021

Abstract
This paper introduces a novel process for creating conductive copper traces on 3D surfaces from different additive manufacturing technologies by employing printed electronics techniques. An essential step in this process was the dip-coating pre-treatment with a primer to reduce the surface roughness below 100 nm, seal pores if present, and increase the thermal stability. This was followed by a dip-coating with copper nanoparticle ink, drying using a heat gun and thermal curing by laser sintering. The experiments determined the optimal laser peak intensity for achieving conductors with the lowest electrical resistance possible. The laser parameters’ processing window provided conductive traces on 3D surfaces with properties comparable to photonic sintering on planar substrates. Thereby, the conductive traces reached electrical specific resistances lower than 18 µΩ cm (elemental copper: ρ = 1.8 µΩ cm) and a copper material percentage higher than 90 atom %. Shear tests validated the assembly with surfacemount device (SMD) resistors. Electrical tests resulted in maximum current densities higher than 100 A mm−2 and lateral breakdown voltages higher than 2kV mm−1. Thus, this paper presents essential prerequisites for a future application of the technology.
