Topological acoustic waveguides have a potential for applications in the precise transmission of sound. Currently, there is more attention to multi-band this field. However, achieving tunability operating band also great significance. Different from previous studies, paper proposes replace two-dimensional (2D) resonant cavity scatterer with an extended three-dimensional (3D) cavity. In way, composite structure consisting 2D and 3D constructed. By controlling position bottom cavity, length...
Getah virus (GETV) is a mosquito-borne with broad host range, including mosquitoes and various animals such as pigs, horses, goats, cattle, boars, blue foxes. In GETV can cause fever, abortion reproductive disorders in sows, well tremors, diarrhea piglets, posing serious threat to the pig production industry. However, there are few reports on epidemiology of China, reliable diagnostic kits for large-scale detection antibodies lacking. Therefore, this study aimed establish rapid, sensitive...
The fourth member of the Triassic in Tahe Oilfield, as one key strata for clastic rock reservoirs, poses significant challenges to oil and gas exploration due unclear identification its depositional environments sedimentary microfacies. Based on guidance sequence stratigraphy sedimentological theories, this study comprehensively analyzed well logging data from more than 130 wells, core analysis 9 coring wells (including lithology, structures, facies characteristics), 3D seismic (covering an...
<sec><title>Objective</title> Existing explorations of Chinese classical gardens have predominantly relied on qualitative analysis. The emergence quantitative research using space syntax has offered a solution to this issue. Although the applicability been validated with eye-level and knee-level application patterns being explored, most such applications lack systematic in-depth analysis, thereby limiting their practical effectiveness. To address these issues, aims integrate theory methods....
Abstract Hydrothermal activities occurred in the Yangtze block, South China, and affected process of black shale sedimentation early Cambrian. Their specific influences, such as sources, sedimentary environment, mineralization, have not yet been revealed. Fortunately, influences are explained through geochemistry comparison different wells FY1, XJ1, HY1, XA1 northwestern Hunan. The outcomes tectonic setting, distinguishable by element indicators, disorganized. This is caused variable...
<bold>Objective</bold> The objective of this study was to construct a recombinant swinepox virus that can efficiently express the p72 protein African swine fever virus,thus exploring feasibility as new live vaccine vector for fever. <bold>Method</bold> In study,the ASFV <italic>B646L</italic> gene synthesized and cloned into universal pUSG11/P28 generate plasmid pUSG11/P28-B646L.The pUSG11/P28-B646L transfected PK15 cells pre-infected with by lipofectamine rSPV-B646L.The screened purified...
The lower Cambrian Niutitang Formation in northwestern Hunan, South China, has already reached its high or over matured stage and is formed with hydrothermal activity deposition. Thus, it extremely difficult to predict the total organic carbon (TOC) content accurately by common methods well-logging data. To solve this problem, we use artificial neural networks for predicting TOC of black shales our study case. We got input vectors through principal component analysis based on relationships...
The gas adsorption of shale is one the most important factors influencing accumulation and production. Different from other fields, in Northwestern Hunan province with strong structural deformation has especially high portion adsorbed gas. abilities reservoir play a significant role success exploration production Hunan. Therefore, based on many experiments including field emission scanning electron microscopy, N 2 /CO adsorption, excess CH 4 constant temperature others, this paper found...
The transformation mechanism of muddy carbonate rock by the coupling bioturbation and diagenesis was studied based on core, cast thin section physical property data Cretaceous strata in Mesopotamia Basin, Middle East. There are 3 ways biological rocks: (1) living creatures transformed formations mechanically to make rocks looser intergranular pores increase. (2) After formation, burrows were backfilled with coarse-grained debris, then unsaturated fluid infiltrated into during...
Abstract The Miocene Zhujiang Formation is the key horizon for oil and gas exploration in Pearl River Mouth basin of northern South China Sea. With help core observation, seismic attributes various analytical data, sedimentary facies marks, distribution depositional model forced regression basin, Sea, have been studied. Forced regressive deposits were formed during period when relative sea level ranged from highstand to lowstand sediments undergo progradation so that five sets foreset delta...
Abstract Logs in the petroleum boreholes indirectly records sedimentary cycles deep burial formation. In order to extract and understand periodicity cyclicity, it is necessary process data by digital signal analysis method. Taking gamma ray (GR) log as primary material, an identification approach of Milankovitch proposed this paper, which based on Maximum Entropy Spectral Analysis (MESA). The first stage chooses appropriate windows for calculating frequency spectral properties a short...
Using 2D/3D seismic data and a large number of drilling logging applying sequence stratigraphy, sedimentology, petroleum geology concepts, the characteristics sedimentary forced regression have been analysed, migration trajectory coastline reconstructed, evolution model presented, significance for regressive sandbodies discussed. The falling stage systems tract (FSST) Zhujiang Formation present offlap high-angle oblique foreset reflection structure in profiles depositional trends turbidite...
Organic-rich shales were found in the Ordovician to Silurian Wufeng-Longmaxi Formation northwestern Guizhou province, China, which has high shale gas content revealed by field measurement. Shale occurrence, free gas/sorbed ratio, and their influencing factors are crucial for exploitation strategy. Results indicated that dominated type I kerogen, with total organic carbon (TOC) equivalent vitrinite reflectance (eqvRo) of 0.77%–6.98% 2.37%–2.53%, respectively. The porosity permeability range...
