Objective: In this study, we compared the biochemical markers of imminent abortion, missed abortion, and healthy pregnant women in the first trimester to see if there were any differences. Materials and Methods: The study method is prospective. Pregnant women who applied to the obstetrics clinic of Istanbul Training and Research Hospital between 01.04.22 and 31.10.22 were diagnosed with abortion imminens or missed abortion between 6 weeks and 12 weeks or had normal pregnancy follow-up, had no chronic diseases, and did not take magnesium and calcium supplements were included in the study. 20 pregnant women with missed abortion, 20 pregnant women with abortion imminens diagnosis and 20 normal pregnant women who met the criteria were included in the study. Magnesium (Mg), calcium (Ca), copper (Cu), zinc (Zn) and hemogram (CBC) levels were checked in pregnant women included in the study. Results: The Mg, Cu, Zn, and CBC values of the study participants’ women did not differ in a statistically significant way. When compared to pregnant women who had a normal pregnancy process, the difference in Ca value was found to be statistically substantially smaller in pregnant women who were diagnosed with abortion imminens and missed abortion. The findings of our study suggest that serum Ca levels be measured prior to conception or at the initial visit. Conclusion: Serum Ca levels were found to be significantly lower in the missed abortion group than in the abortus imminens and normal pregnant groups in our study (p 0.05).

2D all-organic perovskites refine flexible electronics

Science China Materials 2024年第7期67卷 2365-2366页

Recent years have witnessed a paradigm shift with the advent of perovskites,a class of materials with a distinct CaTiO_(3)-type crystalline structure that show remarkable promise across a wide array of applications,including photovoltaics,photodetectors,lighting,lasers,and so *** them,the development of two-dimensional(2D)perovskites has garnered significant attention due to their tunable structures(mainly Dion-Jacobson and Ruddlesden-Popper structures)and enhanced stability in comparison with their 3D counterparts[1].Amidst the burgeoning research on perovskites,on the other side,all-organic perovskites stand out as a particularly intriguing subset[2].Unlike traditional perovskites that typically comprise all-inorganic(e.g.,CsPbBr_(3))or organic-inorganic hybrid components(e.g.,(PEA)_(2)PbI_(4)),all-organic perovskites are composed entirely of carbon-or nitrogen-based molecules.

Fractures interaction and propagation mechanism of multi-cluster fracturing on laminated shale oil reservoir

The continental shale reservoirs of Jurassic lianggaoshan Formation in Sichuan Basin contain thin lamina, which is characterized by strong plasticity and developed longitudinal shell limestone *** improve the production efficiency of reservoirs by multi-cluster fracturing, it is necessary to consider the unbalanced propagation of hydraulic fractures and the penetration effect of fractures. This paper constructed a numerical model of multi-fracture propagation and penetration based on the finite element coupling cohesive zone method; considering the construction cluster spacing, pump rate,lamina strength and other parameters studied the influencing factors of multi-cluster fracture interaction propagation; combined with AE energy data and fracture mode reconstruction method, quantitatively characterized the comprehensive impact of the strength of thin interlayer rock interfaces on the initiation and propagation of fractures that penetrate layers, and accurately predicted the propagation pattern of hydraulic fractures through laminated shale oil reservoirs. Simulation results revealed that in the process of multi-cluster fracturing, the proportion of shear damage is low, and mainly occurs in bedding fractures activated by outer fractures. Reducing the cluster spacing enhances the fracture system's penetration ability, though it lowers the activation efficiency of lamina. The high plasticity of the limestone interlayer may impact the vertical propagation distance of the main fracture. Improving the interface strength is beneficial to the reconstruction of the fracture height, but the interface communication effect is limited. Reasonable selection of layers with moderate lamina strength for fracturing stimulation, increasing the pump rate during fracturing and setting the cluster spacing reasonably are beneficial to improve the effect of reservoir stimulation.
