Transperineal sonographic assessment of the angle of progression before the onset of labour: how well does it predict the mode of delivery in late-term pregnancy
Authors: Güner Gazi , Barut Adil , Okcu Nefise Tanridan 
Published: September 2024

Abstract

Objectives
Predicting the success of vaginal delivery is an important issue in preventing adverse maternal and neonatal outcomes. This study sought to examine whether measurement of the angle of progression (AoP) can predict a successful vaginal delivery following induction of labour (IoL) among late term nulliparous women with a low (4>) Bishop score.

Methods
This prospective study included consecutive nulliparous pregnant women whose gestational age was 41 weeks and 1–6 days (late-term). The AoP was measured at least three times and their means were calculated.

Results
During the study period, data of 150 women were included in the final analysis. Thirty-eight women underwent CS due to failure to progress (n=30) or NRGHR (n=8), while the remaining 112 women underwent NVD, with four women requiring vacuum extraction. The two groups were similar with respect to age, gestational age, BMI, estimated foetal weight, and birth weight. Women undergoing NVD differed significantly from those undergoing CS with respect to a greater ultrasonographic AoP (113.8±11.9° vs. 98.1±10.9°, p=0.0001), a shorter duration of dinoprostone use, shorter time to labour contraction, and a shorter duration of labour. In ROC analysis, the cut-off value for AoP was 100° for the prediction of successful IoL for NVD, with a sensitivity of 96 % and a specificity of 63 %.

Conclusions
AoP may be a useful sonographic parameter for predicting successful vaginal delivery among nulliparous women at late term undergoing IoL; an AOP wider than 100° is associated with a high rate of vaginal delivery.
Proaktives, reaktives und reziprokes Wohlwollen. Kants System der Liebespflichten
Authors: Schmidt Elke Elisabeth 
Published: September 2024

Abstract
Kant’s duties of love include the duties of beneficence, gratitude, and sympathetic participation. But what is it that allows Kant to bring such seemingly quite heterogeneous duties under one concept, especially under the concept of love? I will argue that it is benevolence as an essential element of love that takes on this unifying role. In order to understand this role of benevolence as the unifying element of the three duties of love, the concept of benevolence will first be analyzed (part 1). Against this background, all three duties of love are then reassessed. Beneficence will be shown to be a proactive form of benevolence (part 2), gratitude to be a reactive form of benevolence (part 3), and sympathetic participation is understood as a form of reciprocal benevolence (part 4).
The Moral Law as an A Priori Principle. Kleingeld and Willaschek on Autonomy
Authors: Sensen Oliver 
Published: September 2024

Abstract
According to a common reading of Kant, autonomy refers to the idea that pure reason gives the moral law to itself. Pauline Kleingeld and Marcus Willaschek reject this standard view both on textual as well as philosophical grounds. Instead, they argue that autonomy only selects mid-level principles, such as ‘help others,’ and that the moral law is a priori and not given. – In this paper, I first analyze on textual grounds what Kant means when he says that a principle is a priori. I argue that Kant does not conceive of a priori laws as permanently existing entities. Rather they are the product of how reason necessarily functions if it is prompted by sensibility. Kant also uses the word ‘autonomy’ in this context. I then argue that this non-standard view of autonomy as an activity can meet the philosophical objections that Kleingeld and Willaschek raise against autonomy as a giving of the moral law.

Abstract
In this study, the electrospinning technique was employed to create a nanofiber membrane by stretching an organic polymer into nanofibers under a high electric field. Metronidazole (MNZ) at a concentration of 3 wt% was loaded into a poly(lactic-co-glycolic acid) (PLGA) and silk fibroin (SF)-blended nanofiber membrane. This formulation aims to achieve effective and sustained drug release, enabling the eradication of bacteria for the efficient treatment of periodontitis. Results demonstrated that SF interacted with PLGA molecules, forming dense and uniform nanofibers with a diameter of 570 nm. Excessive SF molecules tended to aggregate, leading to an increased particle size, with the interaction between MNZ and SF contributing to adhesion. The composition of MNZ, SF, and PLGA formed a physical chimera without any chemical reactions. Moreover, as the SF content increased, the tensile properties of the membrane gradually improved. Concurrently, the in vitro degradation rate increased with higher SF content. Among the various groups tested, the 3 wt% MNZ/PLGA/SF 2:1 membrane exhibited superior drug release characteristics, with 71.76% release within 24 h. This formulation demonstrated excellent antibacterial properties, indicated by a bacterial inhibition diameter of 13.5 mm, noteworthy hydrophilicity with a contact angle of 44.3°, and favorable biocompatibility. The membrane holds significant application value in regenerative engineering and drug delivery systems, showcasing substantial potential for the treatment of periodontitis.
Study on dynamic and static tensile and puncture-resistant mechanical properties of impregnated STF multi-dimensional structure Kevlar fiber reinforced composites

Published: September 2024

Abstract
Shear thickening fluid (STF)-impregnated Kevlar fabric can be used as “Liquid armor” for the protection of weapons and equipment. The concentration of dispersed phase in STF and the fabric structure are important factors that affect the mechanical properties of composites. To obtain the mechanical properties of Kevlar fabric impregnated with STF, nano-sized silicon dioxide particles (SiO2) and Polyethylene glycol were used as dispersing phase and dispersing medium, respectively, by impregnating Kevlar fabrics with 2D planar and three-dimensional (3D) angular interlock structure, fiber-reinforced composite fabrics impregnated with STF with different physical structures were obtained. The results show that the shear thickening behavior of STF is the most obvious when the concentration of STF is 60%. In addition, fabric structure and STF concentration play an active role in the mechanical properties of STF/Kevlar fiber reinforced composites. Compared with pure Kevlar fabric, the maximum tensile load and the maximum puncture load of the three-dimensional angular interlocking structure of STF/Kevlar fiber reinforced composites are increased by more than 13,000 N and 120 N, respectively. The research results can provide theoretical support for the mechanical properties of STF/Kevlar fiber-reinforced composites and individual protection research.
Low thickness electromagnetic wave absorbing polyurethane and IIR composites by interfacial polarization of multi-layer structure
Authors: Yang Jinghui 
Published: September 2024

Abstract
Electromagnetic cooperative strategy has been proved to be an effective approach that can significantly decrease the matching thickness required for reflection loss. However, improving the electromagnetic wave (EMW) absorbing effectiveness with low matching thickness remains challenging for current single-phase absorbing materials. A layer-by-layer construction design is used in our study via a combination with iso-butyl isoprene rubber (IIR) and mixed polyurethane (MPU) as the matrix, with the single-wall carbon nanotubes (SWCNTs) and magnetic powder as fillers. This bilayer composite design resulted in a decrease in matching thickness and a shift in absorption bandwidth to higher frequencies by 40 %–50 %. Furthermore, the trilayer structure of MPU/IIR/MPU was found to stabilize permeability, enhance the thermal stability of the magnetism and improve the shielding effectiveness significantly. The thickness corresponding minimum absorption loss of the trilayer composites decreased and the absorption bandwidth of −10 dB widened by 50 % from 8.2 GHz–9.5 GHz to 10.2 GHz–12.4 GHz.

Published: September 2024

AbstractThis research investigates the complex interplay between stress impact, concrete shrinkage, and its implications on crack development. Utilizing theoretical and computational methods, the study analyzes the detrimental effects of structural cracks caused by stress variations. A distinctive behavior of long-term shrinkage concerning stress levels was observed. It was found that, positive stress enhances the mean Young's modulus, while negative stress reduces modulus under negative stress conditions, heightened susceptibility to crack propagation under negative stress and improved resistance under positive stress. Temperature's uniform impact on long-term shrinkage is demonstrated, highlighting differences among various cement classes.

‘To Make Britain Concrete Minded’: Peter László Peri’s <em>London Life in Concrete</em> (1938)
Authors: Aukland-Peck Tobah J 
Published: September 2024

In 1938, sculptor Peter László Peri staged a solo exhibition in London titled London Life in Concrete, a selection of sculptural works fabricated out of concrete. Contemporaneous critics enthused about Peri’s experiments with the exciting new medium. Multi-coloured relief works, set on a high ledge that encircled the room, showed scenes of everyday life in the capital: figures of shoppers, builders, and commuters arrayed across flattened backgrounds. The simple format of these sculptures belied the political entanglements of Peri’s chosen material. Rough finishes typify Peri’s concrete works, both those exhibited in London Life in Concrete and those later commissioned to decorate a post-war public housing complex in London. Their explicitly modelled surfaces present the medium as one tied to human labour and equate the work of builder and of artist. London Life in Concrete was sponsored by the Cement and Concrete Association (CCA), a new trade group established to promote the use of concrete in building projects in Britain. This paper traces the history of Peri’s concrete sculptures and the relationship between Peri and the CCA. It reveals the role that Peri’s work played in the commercial project to establish concrete as the architectural material best suited—both practically and ideologically—to the homes of the British working class.

O foco do trabalho pericial está direcionado em identificar e recolher os vestígios em cenas de crime. Todo o material recolhido pode passar por análises, como de DNA, que possibilita determinar autoria do delito, por meio da utilização de marcadores moleculares. O objetivo do presente trabalho é apresentar um relato de caso, destacando a viabilidade, eficiência do trabalho pericial tanto na cena de crime, quanto no Laboratório de Biologia em união com a investigação policial. Trata-se de um crime sexual envolvendo dois indivíduos do sexo masculino, em cuja cena do crime foram coletadas amostras questionadas para realizar a comparação entre as amostras dos envolvidos. Os perfis genéticos das amostras 2 (unhas postiças da vítima) e 3A e 3B (preservativo do quarto), apresentaram correspondência com a amostra referência da vítima. A amostra questionada 4A (preservativo sanitário parte externa) apresentou uma mistura de material genético de duas pessoas do sexo masculino e já as amostras questionadas 4B (preservativo sanitário parte interna) e 5 (lençol da cama) apresentaram perfil correspondente ao suspeito. É interessante mencionar que o fluxo das atividades investigativas permitiu a busca do suspeito mesmo após o término das análises laboratoriais. Assim, a garantia de que todos os procedimentos foram adotados para manter a cadeia de custódia, permitiu que novas análises do caso fossem realizadas com sucesso. As análises do suabe oral do suspeito encaminhado posteriormente pelo IML, levaram à sua inclusão juntamente com a vítima, como produtor de um dos perfis genéticos da mistura extraída no preservativo. Destacam-se pontos importantes para o desfecho exitoso apresentado no presente relato de caso. O primeiro se refere à adequada coleta e preservação dos vestígios biológicos encontrados no local, permitindo a adequada obtenção de produtos de amplificação de DNA nos procedimentos laboratoriais. O segundo se refere à garantia de manutenção da cadeia de custódia, além da integração entre atividades investigativa e pericial durante o trabalho policial.

Authors: Khabrat Ghulam Rasoul , Puzin Yuri I. 
Published: September 2024

Due to the low density and high chemical resistance of polymers compared to metals, the use of polymer composite materials in various industries is growing. On the other hand, because of the low strength of polymers, it is necessary to reinforce them, including micro- and nanoparticles.In recent years, one of the achievements in the industry of plastics and composite materials has been the nanocomposites development and production. They found application in automobile and airplane construction, household appliances and medical equipment.There are various processes for nanocomposite production, such as extrusion and mixing. The limitation of these processes is the high cost, multi-stage production process and the amount of nanosized reinforcing particles (not more than 5 % by mass). Recently, studies on the use of friction with mixing (friction mixing) method for the composite and nanocomposite production were conducted. Using this method for polymer composites and nanocomposites production, in the main polymer sheet a groove of certain sizes is made, and nanoparticles are inserted into this groove. Then the rotating tool is loaded into the sheet and moved along the groove to distribute the particles on the main material.

Deethanization unit is a part of the process chain of a gas processing plant included in the ethane gas processing complex, and is designed to separate dehydrated and purified natural gas (NG) into dry stripped gas (DSG), ethane fraction and natural gas liquids (NGL). Low-temperature separation of dried and purified NG is carried out in two stages in column-type apparatuses. One of the most important blocks responsible for ethane fraction recovery depth at the deethanization unit is the gas treatment block before it is fed to the demethanization column. In this unit gas is cooled, separated and reduced, ethane-containing condensates are separated. In the present article the main technologies of natural gas processing are considered. The peculiarity of known technologies is low yield of ethane fraction due to insufficient gas cooling. The aim of the work is to increase the yield of marketable products during natural gas processing at the gas processing plant by using the deflegmation process. In order to achieve this aim, five variants of the gas treatment system before its supply to the demethanization column are analyzed in the article. Calculation studies and optimization of the natural gas treatment unit were carried out in the Aspen HYSYS software package. In order to select the optimal scheme of the gas treatment unit, in the article there were considered the following parameters: ethane fraction recovery depth, ethane concentration in DSG, temperature of the demethanizer top. It is determined that high recovery depth and low ethane losses in the demethanization column are ensured by using deflegmation process in the gas treatment system. The main technological solution is to use deflegmation of separation gas by using technological cold and isoenthalpic (throttling) expansion of gas. The result of the research is a calculation scheme in Aspen HYSYS, in which the ethane recovery depth is 96.7 %.

The existing economic conditions caused by geopolitical risks require accelerated import substitution and import outrunning, especially in strategically important sectors of the economy, which include the Oil and Gas Complex of the Russian Federation.Especially, it is worth considering equipment directly affecting the productivity and safety of work, where it is impossible to use outdated solutions and to exceed the safe operating time. If the majority of the operated units of the definite equipment are manufactured abroad or contain a significant proportion of foreign components, there are risks of untimely repairs of the equipment itself, as well as re-equipment and technical up-grading of production facilities as a whole.The main and perspective solution of this problem is exclusively the development and commissioning of Russian equipment samples in the industry. The initiatives of equipment manufacturers, their cooperation and interaction with future consumers are key factors in the successful implementation of projects.Having created a prototype or even a serial sample, the manufacturer inevitably faces the problem of launching a new product to market. To check the safety and effectiveness of the equipment, to recommend it among the operators today is necessary during pilot tests implementation. At the same time, pilot tests implementation is expensive both in terms of the degree of material, technical and human resources attraction, and in terms of time factor. Due to the fact that equipment life cycle lasts about 10 years, spending at least one year, that is, in the best case 10 % of the time on the development of a domestic innovative product, on obtaining the results of pilot tests, after which adjusting to the production chain are seen as irrelevant and inhibiting the development of innovative machinery and equipment.The article is devoted to the description of the procedure and experience of the approbation process implementation as the fastest, most flexible and effective tool for launching to market, re-equipping and upgrading innovative equipment that can at the same time guarantee the safety of the technological processes in which it is involved.

Abstract
Since 2000, eastern Taiwan has experienced 38 Mw≥5.5 earthquakes, leaving three seismic gaps along the Longitudinal Valley fault (LVF). In April 2024, the Mw 7.3 Hualien earthquake occurred near the LVF. Herein, we first apply comprehensive geodetic data including Interferometric Synthetic Aperture Radar and Global Navigation Satellite System to estimate two potential fault geometries and invert for the coseismic slip. Our results suggest that a transpressive WNW-dipping low-angle fault related to the Central range fault is responsible for the Mw 7.3 Hualien earthquake. We then perform the Coulomb stress analysis to probe earthquake interaction in eastern Taiwan. The increased stress of ∼2.6 bars due to the preceding major earthquakes at the hypocenter of the 2024 event significantly pushes this fault toward failure. Moreover, the conjugate LVF and the Milun fault are activated, and some aftershocks are promoted here. Finally, we note that the Coulomb stress changes from historical earthquakes and the 2024 Hualien earthquake exert positive stress on the seismic gaps in the northern LVF, potentially influencing future ruptures.
