Endoparasitoids are insects that develop within other insects, employing unique strategies to enhance their offspring’s survival. They inject polydnavirus and/or venom into hosts along with eggs, effectively suppressing the host’s immune system. Polydnavirus from Braconidae and Ichneumonidae wasps can integrate genome express viral genes using transcription systems. However, ability of parasitoids without manipulate host gene expression remains unclear. Lysine acetylation (LysAc), a...

Recycled cement paste (RCP) is a kind of CaO-rich recourse, which separated and recycled from waste concrete. Due to its chemical composition, RCP could partially replace lime as flux be loaded into electric arc furnace (EAF) steelmaking process. Rapid assimilation liquid slag formation have significant effects on EAF In this study, the dissolution behaviours at temperatures 1400°C 1500°C were investigated using static experiment. The rate, interfacial microstructure, well mechanisms...

Abstract The onset of uplifting the Mid‐upper Yangtze area is constrained by combination analysis apatite fission track (AFT) age and modeling length distribution. results show that general trend characterized decreasing westward in geological time for different tectonic units area. Two episodes Jianghan basin occurred within 157~97 Ma 10~0 Ma; Xiang'exi‐Wuling experienced an 137~0 E'xi Yudong area, Chuandong folds, Qianzhong Hights Dian‐Qian‐Gui areas 97~0 Northern Sichuan Chuanzhong 56~0...

Abstract In order to explore the influence of micropore structure tight sandstone reservoir in water driving characteristics, studies on Chang 6 middle-western part Ordos Basin are carried out by various experiments such as cast-thin section analysis, scanning electron microscopy, high-pressure mercury injection and micro-water driving. The result shows that permeability contribution curves samples shift left sample decreases, indicating greater permeability, proportion large pores. is...

Abstract The comprehensive utilization of steel slag has always been a worldwide problem. Under the background vigorous development highways in China, application technology asphalt concrete will make resources hopefully get large number reasonable utilization. Based on concrete, basic physical and chemical properties different types were investigated. blast furnace was used as aggregate to prepare mixture. mixture tested by research test. uniaxial compression test indirect tensile evaluate...

ABSTRACT This clinical report details the functional and aesthetic rehabilitation of a patient with severe maxillary defect secondary to subtotal maxillectomy for oral squamous cell carcinoma (OSCCM) using prosthesis anchored by four zygomatic implants. The procedure involved meticulous repair implant support, incorporating advanced digital surgical methods, including 3D reconstruction, computer-guided surgery, photogrammetry (Icam4D). A finite element analysis (FEA) was conducted assess...

Tie-in is a very important step on the final stage of pipe construction. The stress tie-in girth weld really one key roles that affect security pipeline in service. In this paper, Finite Element Method (FEM) was used to determine weld. factors were analyzed. results show uncovered length, offset and misalignment which maximum Mises axial at increased with length decreasing increasing. also significantly misalignment, especially for stress.

Aiming at the change law of flexural and tensile strength modified steel slag asphalt mixture during microwave heating, results this paper are as follows: heating process can achieve recovery properties mixture. The number point bending failure tests continues to increase, rate beams made will slowly decrease until test piece is completely destroyed. by cannot be fully recovered, but different mixtures have effects. Compared with ordinary basalt mixture, before modification has same repair...

Abstract Tight sandstone reservoirs dominated by are developed in the Chang 6 oil layer group of Yanchang Formation central-western part Ordos Basin. Featuring lacustrine delta facies, formation center-west area Basin shows an increasing petroleum reserve expectation. Its exploitation practice, however, has many problems caused tight reservoir features. According to diagenetic and pore analysis, facies study grouped into four types: chlorite-film-intergranular-pore, feldspar-dissolution,...

With the rapid development of national economy, combined with construction strategic reservation petroleum in China, difficulty large-scale energy storage and peak-shaving comes up. In recent years, U.S. Department Energy (DOE), Bonneville Power Administration (BPA), Pacific Northwest National Laboratory (PNNL) a number companies launched two projects Columbia Basin to evaluate technical economic feasibility underground gas wind power basalt interflow aquifers. These reveal potential...

The outer surface of external wall with lightweight thermal insulating layer is easily destructed when a building in service. In this paper, the basic destructive forms are sorted out, such as cracking, hollowing, shedding. And correlating factors which cause different fractures have also been discussed. By survey and analyses, lack mechanical design, improper application materials misuse construction can be inferred key additional stress incongruous deformation over-breaking permission...

Abstract As the largest amount of industrial waste, people have been unable to recognize use value coal gangue. In many industries, gangue has no main use. However, in process road construction, recognized by people. Because its high hardness and good water stability, can be used as a material for subgrade construction. order broaden application prospect engineering, this paper analyzes performance asphalt mortar with powder component finally draws conclusion.

Abstract steel slag property reform is the main form of comprehensive utilization industrial waste resources. Therefore, this paper combines theory surface modification technology, focusing on expansion characteristics, aggregate effect and other aspects, to explore performance modified asphalt mixture, in order achieve clear technical points, purpose development application social

The road performance evaluation method, determining the asphalt mixture inaccurate index, resulting in a stable and freeze-thaw splitting strength variation assessment before after immersion, is proposed for this neural network based on chaos optimization slag Modified Asphalt Mixture Pavement methods. Analysis of mixture, index composition determined modified index; full Chaotic convergence speed fast high accuracy, establishment model; calculating pavement structural coefficient, with...
