Particle flow velocity detection technology based on electrostatic induction method and urban block distance method
Authors: Chen Jiange 
Published: July 2021

Abstract
Aiming at the problem of difficulty in detecting the velocity of coal dust particles in pneumatic conveying coal dust pipelines, this study is based on electrostatic induction method and urban block distance algorithm to achieve accurate detection of coal dust velocity in dust conveying pipelines. Firstly, the principle of electrostatic induction is introduced in this paper. The dust particles with static electricity can sense fluctuation signals on the surface of the metal detector electrode. Then two electrostatic sensors are designed and installed on the upstream and downstream of the dust conveying pipeline. The actual flow velocity of coal dust is obtained by using the urban block distance method to analyze the electrostatic induction signals generated with the two sensors. Compared with the current cross-correlation algorithm, the urban block distance method has the advantage of better real-time performance and less computation. Finally, the experimental results show that the detection error of the coal dust velocity detection technology based on the electrostatic method and the urban block distance method is small, and the maximum absolute error does not exceed 0.16m/s compared with the velocity of the airflow. The results are reliable and effective.

Abstract
The growth of hermophilic cyanobacteria Thermosynechococcus elongatus PKUAC-SCT E542 was not inhibited when the leachate from the flue fly ash of waste incineration plant was added to the culture of cyanobacteria, and the growth of cyanobacteria was not inhibited. Some elements in the BG-11 medium could be used with smoke Dow fly ash leachate was replaced, and the growth rate was increased by 6% to 12% compared with the use of BG-11 medium. In addition, combining the use of fly ash leachate and simulated flue gas to replace Na2CO3 in the microalgae culture system as the sole carbon source, the growth of cyanobacteria was still active, and there was no significant difference compared to BG-11. After 4 days of cultivation, the biomass yield was 0.805 ± 0.05 g/L and 0.751 ± 0.02 g/L, achieving a higher biomass accumulation efficiency, and realizing the feasibility of replacing medium components with leachate and flue gas at the same time. In this system, the cultivation of thermophilic cyanobacteria and the two major pollutants of power plants were mutually beneficial, and at the same time achieve the results of resource utilization of pollution sources, reduction of cultivation costs and production of phycobiliprotein(PBPs).

Published: July 2021

Abstract
When steel structure is adopted in the main building of domestic thermal power plant, steel frame-center support structure is often adopted. The main building of a 2×660MW thermal power plant in Turkey is located in a high-intensity area, the earthquake area is Zone 1, and the building site category is Z2. In order to make the structure have better ductility and energy dissipation capacity under rare earthquakes, the structure adopts the form of steel frame-eccentric support structure. Through the nonlinear static analysis of the structure, the performance of the structure under the action of rare earthquakes is studied, which provides reference experience for future engineering design. The analysis results show that the energy dissipating beam has played a good role in dissipating energy under the action of rare earthquakes, effectively protecting the main structure, and the structure has not entered a collapsed state.

Abstract
According to the national nuclear power plan, the high-level radioactive waste should be disposed safety and effectively. And the deep geological disposal is the main way, which is influenced by the surrounding rock and soil, especially the physical and mechanical properties. Currently, the SHPB is mature equipment for the material’s dynamic testing. It is mainly used to load the entire specimen, however, the specimen with the pre-crack is less used. Firstly, it should satisfy two hypotheses, i.e. the one dimension stress wave and the stress equalization when using the SHPB to measure the mechanics characteristics of the material, especially for the pre-cracked specimen. Then, from the point of stress equalization along the specimen, emphasize the importance of the dynamic force equilibrium during the testing data processing. Finally, the SHPB testing system could also be applied to the pre-cracked specimen has been proposed.

Effect of Myriophyllum verticillatum on controlling phosphorus release from sediment for water environment purification
Authors: Wang Shujing , Lin Tian , Liu Xiao , Chen Xiang 
Published: July 2021

Abstract
Eutrophication is one of the most common water pollution problems in the world. In this paper, the effects of Myriophyllum verticillatum on phosphorus content in water and sediment were studied. The results showed that Myriophyllum verticillatum had the strongest purification effect on water sample. Under the condition of sufficient light, suitable temperature and environmental factors not affected by the external environment, the phosphorus content in the overlying water increased first and then decreased. In addition to the external factors, the phosphorus content in the water decreased. The results show that the growth of Myriophyllum verticillatum depends on the change of phosphorus concentration in water. The increase of phosphorus concentration in water will increase the phosphorus concentration in plants and accelerate the growth of Myriophyllum verticillatum. However, the growth of Myriophyllum verticillatum will consume more phosphorus. Myriophyllum verticillatum in sufficient light, suitable temperature, environmental factors are not affected by the outside world. The contents of phosphorus in the sediments showed a downward trend. In addition to the external factors, the phosphorus content in the sediment was reduced by Myriophyllum verticillatum. The relationship between the growth of Myriophyllum verticillatum and the total phosphorus concentration in sediments is interdependent. The release of phosphorus in sediment will increase the phosphorus content in water, which will lead to the enrichment of phosphorus in plants and accelerate the growth of Myriophyllum verticillatum. The growth of Myriophyllum verticillatum will make Myriophyllum verticillatum need more phosphorus, which will accelerate the absorption of phosphorus in water and release more phosphorus from sediment. This is the reaction mechanism of phosphorus removal by Myriophyllum verticillatum; Under the conditions of sufficient light, warm climate and environmental factors not affected by the external environment, the total phosphorus content of Myriophyllum verticillatum was on the rise.

Abstract
Febrile seizures represent the most common type of pathological brain activity in young children and are influenced by genetic, environmental and developmental factors. In a minority of cases, febrile seizures precede later development of epilepsy.
We conducted a genome-wide association study of febrile seizures in 7635 cases and 83 966 controls identifying and replicating seven new loci, all with P &lt; 5 × 10−10.
Variants at two loci were functionally related to altered expression of the fever response genes PTGER3 and IL10, and four other loci harboured genes (BSN, ERC2, GABRG2, HERC1) influencing neuronal excitability by regulating neurotransmitter release and binding, vesicular transport or membrane trafficking at the synapse. Four previously reported loci (SCN1A, SCN2A, ANO3 and 12q21.33) were all confirmed. Collectively, the seven novel and four previously reported loci explained 2.8% of the variance in liability to febrile seizures, and the single nucleotide polymorphism heritability based on all common autosomal single nucleotide polymorphisms was 10.8%. GABRG2, SCN1A and SCN2A are well-established epilepsy genes and, overall, we found positive genetic correlations with epilepsies (rg = 0.39, P = 1.68 × 10−4). Further, we found that higher polygenic risk scores for febrile seizures were associated with epilepsy and with history of hospital admission for febrile seizures. Finally, we found that polygenic risk of febrile seizures was lower in febrile seizure patients with neuropsychiatric disease compared to febrile seizure patients in a general population sample.
In conclusion, this largest genetic investigation of febrile seizures to date implicates central fever response genes as well as genes affecting neuronal excitability, including several known epilepsy genes. Further functional and genetic studies based on these findings will provide important insights into the complex pathophysiological processes of seizures with and without fever.

Abstract
Prompt antiviral treatment has the potential to reduce influenza virus transmission to close contacts, but rigorous data on the magnitude of treatment effects on transmission are limited. Animal model data indicate that rapid reductions in viral replication after antiviral treatment reduce the risk of transmission. Observational and clinical trial data with oseltamivir and other neuraminidase inhibitors indicate that prompt treatment of household index patients seems to reduce the risk of illness in contacts, although the magnitude of the reported effects has varied widely across studies. In addition, the potential risk of transmitting drug-resistant variants exists with all approved classes of influenza antivirals. A controlled trial examining baloxavir treatment efficacy to reduce transmission, including the risk of transmitting virus with reduced baloxavir susceptibility, is currently in progress. If reduced transmission risk is confirmed, modeling studies indicate that early treatment could have major epidemiologic benefits in seasonal and pandemic influenza.

Abstract

Aim
Preclinical work indicates that low-density lipoprotein cholesterol (LDL-C) not only drives atherosclerosis by directing the innate immune response at plaque level but also augments proinflammatory monocyte production in the bone marrow (BM) compartment. In this study, we aim to unravel the impact of LDL-C on monocyte production in the BM compartment in human subjects.

Methods and results
A multivariable linear regression analysis in 12 304 individuals of the EPIC-Norfolk prospective population study showed that LDL-C is associated with monocyte percentage (β = 0.131 [95% CI: 0.036–0.225]; P = 0.007), at the expense of granulocytes (β = −0.876 [95% CI: −1.046 to −0.705]; P &lt; 0.001). Next, we investigated whether altered haematopoiesis could explain this monocytic skewing by characterizing CD34+ BM haematopoietic stem and progenitor cells (HSPCs) of patients with familial hypercholesterolaemia (FH) and healthy normocholesterolaemic controls. The HSPC transcriptomic profile of untreated FH patients showed increased gene expression in pathways involved in HSPC migration and, in agreement with our epidemiological findings, myelomonocytic skewing. Twelve weeks of cholesterol-lowering treatment reverted the myelomonocytic skewing, but transcriptomic enrichment of monocyte-associated inflammatory and migratory pathways persisted in HSPCs post-treatment. Lastly, we link hypercholesterolaemia to perturbed lipid homeostasis in HSPCs, characterized by lipid droplet formation and transcriptomic changes compatible with increased intracellular cholesterol availability.

Conclusions
Collectively, these data highlight that LDL-C impacts haematopoiesis, promoting both the number and the proinflammatory activation of circulating monocytes. Furthermore, this study reveals a potential contributory role of HSPC transcriptomic reprogramming to residual inflammatory risk in FH patients despite cholesterol-lowering therapy.
