Authors: Gong Leiyu , Zhou Shengli , Ren Cheli , Zhao Weikai
Published: December 2023

Pipeline transportation has the advantages of safety, reliability and low energy consumption in transporting natural gas, and is an important transportation route for transporting natural gas. Due to the characteristics of natural gas pipelines with large internal pressure fluctuations, plenty of pipeline bending sections and complex pipeline deformation characteristics, pipeline detection robots are required to have higher detection capabilities, and the study of the motion state of natural gas pipeline detection robots in pipeline detection is of practical significance. This paper adopts the CFD numerical simulation method and establishes the model of DN800 pipeline deformation detection robot. Next, by simulating the natural gas pipeline detection robot under different media and different pipeline types respectively, the motion state of the detection robot is analyzed under different conditions. The simulation results verify the reliability of the detection robot working inside the pipeline, which can fully guarantee the safe transportation of natural gas pipeline.
Strategies for solving hydrogen precipitation problems in aqueous zinc ion batteries
Authors: Fan Hanxiao
Published: December 2023

Aqueous zinc ion batteries have revealed many problems while solving the safety problems of conventional batteries, among which the narrow electrochemical stability window of water causes the battery to be prone to hydrogen precipitation reactions. In this paper, we summarize two strategies to solve the problem. From the electrolyte side, firstly, we use a mixture of salt-in-water electrolyte  to lower the starting potential of hydrogen precipitation reaction, so that the hydrogen precipitation reaction can be inhibited. The second strategy is to use intermolecular forces to configure a high concentration electrolyte to change the presence of ions in the solution, thus reducing the free water content and the activity of water to inhibit the hydrogen precipitation reaction.

Authors: Li Ruichuan , Chen Lanzheng , Li Defang , Wang Lin , Li Zhengyu , Zhang Peng
Published: December 2023

In response to the problem of outdated traditional PID control performance and excessively single control parameters in automotive suspension, a two level fuzzy PID control system for automotive semi-active suspension is proposed. The system has two control loops: the first level control loop is PID control, and the second level control loop is fuzzy control. The second level control loop fully utilizes the motion state of unsprung mass that affects the comprehensive performance of the suspension to achieve fine adjustments to the PID controller control parameters in the first level control loop, making the PID controller control parameters more suitable for adjusting suspension performance after hierarchical adjustment, thereby achieving the goal of improving ride comfort. The analysis data shows that the control performance of the two level fuzzy PID control system is significantly better than that of the PID control system, and the comprehensive performance of the suspension and ride comfort has been significantly improved.

Authors: Yang Xiaoxi , Li Jingkui , Liu Xiaona
Published: December 2023

The electric propulsion system of an electric aircraft is the core power of the whole aircraft, which provides assurance for the safe flight of the aircraft. There are multiple stages in the flight process of electric aircraft, as well as different failure behaviors of system components at different stages. The electric motor system is a k-out-of-n system. Therefore, it is not possible to accurately describe the electric motor system with the existing operators when using the GO-FLOW method for electric propulsion system reliability calculations. In order to solve this problem, this paper models the electric motor system using the multi-valued decision diagram method (MDD method), based on which a new operator 43 is proposed to simulate the electric motor system, and then builds the GO-FLOW model and calculates the overall reliability based on the distributed electric propulsion system schematic. The example results show that the method can calculate the reliability of the distributed electric propulsion system more realistically.

Authors: Zhou Jianmei
Published: December 2023

In the process of preparing α-hemihydrous gypsum from desulfurized gypsum under atmospheric pressure, the optimum conditions of crystallization transformation and modification of desulfurized gypsum were studied. The effects of the type and concentration of composite salts (CaCl2, KCl, MgCl2 mixed solution) on the crystallization and modification of desulfurized gypsum were studied. The results were further verified by scanning electron microscopy (SEM) and differential scanning calorimetry (DSC/TGA), so as to determine the ideal directional crystallization control index. The experimental results show that temperature, type and concentration of salt solution are the most sensitive factors in the crystallization process of desulfurized gypsum. The optimal control conditions for obtaining α-hemihydrous gypsum with good crystalline form are temperature 95℃~98℃, concentration of composite salt solution (CaCl2: MgCl2: KCl = 25:5:1) is 25%~30%, and slurry concentration is greater than 20%.

Authors: Gong Yichun , Zhang Jinfang , Wu Cong , Yuan Bo , Zhang Fuqiang , Liu Bin
Published: December 2023

The principle of energy storage promoting new energy consumption was analyzed and the role of energy storage in new energy consumption under different installed penetration rates of new energy was rearranged in this article. In addition, a detailed analysis was conducted on the limitations of daily regulated energy storage on new energy consumption with data from a major new energy province in northwest China as an example. The case results revealed that in case of a high penetration rate of new energy, there will be a gradual weakening in the improvement effect of increasing daily regulated energy storage on new energy consumption and there will be a gradual “saturation” in the utilization rate of new energy accompanied by the increase of energy storage scale. Nonetheless, measures such as the flexible transformation of thermal power and increase of external transmission channels to promote consumption are not related to the “saturation effect”. The conclusion of this article can be as a reference for other countries and regions in the allocation of flexible resources for promoting new energy consumption.

The Italian gender gap in pensions: A cohort of birth approach
Authors: Paiella Monica
Published: December 2023

Introduction: The text discusses the gender pension gap in rich countries, focusing specifically on Italy. The paper delves into the evolution of this gap across different generations, analyzing social security reforms and their impact on retirement incomes. The study emphasizes the importance of understanding these disparities for designing effective pension systems that address gender inequalities and ensure well-being in retirement.Objective: The aim of the article is to investigate the gender pension gap, specifically in the context of Italy, by analyzing the factors contributing to this disparity, including late entry into the job market, wage gaps, and caregiving responsibilities. The study focuses on understanding the impact of social security reforms and the pension system on these gender inequalities, aiming to provide insights for the design of equitable pension systems.Materials and methods: The article utilized administrative data from the Italian National Institute for Social Security (INPS) covering pension payments from 1995 to 2022. The study employed a cohort perspective, analyzing the evolution of the gender pension gap across generations and examining the impact of social security reforms and labor market arrangements.Results: The main conclusion of the study indicates that while the absolute gender disparity in mean retirement income has increased across cohorts of Italian retirees born between 1930 and 1954, the relative gender gap, when considering men's average pension, has decreased over time. Additionally, the impact of survivor's benefits has been significant in reducing the gender disparity in pensions, particularly in the later stages of life. Furthermore, the study found that the impact of social security reforms in Italy has been limited, primarily affecting the youngest cohorts, with most retirees still relying on the dominant defined benefit component for their pensions.
Maritime and port terrorism – aphenomenon analysis
Authors: Osmólska Iwona , Smolarczyk Rajmund
Published: December 2023

Background: In theera of theglobal threat of terrorist attacks, seaports implement anumber of measures to eliminate them. As part of these activities, in addition to threat definition and risk analysis, they also take into account applicable normative documents, both international and national. However, many of these documents equate port terrorist threats with maritime terrorism, which until now has not been clearly defined. It would therefore seem desirable to define terrorist acts threatening seaports as aseparate form of terrorism. Consequently, theresearch problem closed with thequestion: Is maritime terrorism thesame as port terrorism and what factors distinguish them from each other? Objectives: Theaim of this paper is not only to present thetheoretical issues of thesubject, but above all to articulate thefactors that distinguish threats of maritime terrorism from threats of port terrorism and to prove that these are two different issues (problems). Methods: Theoretical research methods were used in this study, i.e. analysis of theliterature, analysis of theacts of maritime terrorism that have occurred so far, and inference, which is acognitive factor of thesubject under analysis. Results: Theresults of theresearch indicate that there are significant differences between aterrorist attack on thehigh seas and aterrorist attack on aseaport regarding not only theconsequences but also thescale of thethreat.

Published: December 2023

El retroceso de los acantilados y la erosión de la franja litoral son los principales factores que vulneran la seguridad de las poblaciones asentadas en el margen de la costa central del Ecuador. Mediante distintos criterios de geomorfológicos y de intervención antrópica utilizados como marcadores geológicos de erosión y retroceso litoral. Se llevó a cabo la caracterización de varios acantilados dentro de algunos sectores costeros de la provincia de Manabí. Se realizó una selección de los acantilados; recopilación de material cartográfico; análisis de oleaje y marea; estudios en campo de parámetros geomorfológicos, hidrodinámicos y antropogénicos; además del análisis de retroceso de acantilados ante la erosión hidrodinámica. El retroceso de los acantilados litorales en cada una de las zonas estudiadas es el resultado de factores tanto geológicos (litología, pendiente de los escarpes, pendiente de playa, presencia de plataformas de abrasión) y de incidencia antrópica (estabilidad de taludes e inadecuada incidencia ingenieril). Cada uno de los escarpes situados en las zonas de estudio evidencia erosión al pie del talud, producto de los procesos erosivos del mar. Los sectores donde resalta la incidencia de factores que vulneran la estructura geomorfológica de los acantilados litorales son más propensos a sufrir daños en construcciones tanto de vías como de complejos residenciales que llevan al abandono de las mismas como ya es evidente en algunos casos.

Published: December 2023

INTRODUÇÃO: As úlceras pépticas podem se desenvolver em qualquer porção do trato digestivo exposta à secreção cloridropéptica. As principais etiologias são: infecção pelo H. pylori e uso de anti-inflamatórios. O diagnóstico é feito pela suspeição clínica e endoscopia. As complicações são sangramento, perfuração, obstrução. RELATO DE CASO: I.C.T.S, 69 anos, transferida para serviço de hospital terciário, com quadro de melena, foi realizado uma endoscopia, a qual mostrou lesão estenosante, ulcerada, infiltrativa e friável em duodeno. Na tomografia havia uma lesão com aspecto infiltrativo na parede do cólon ascendente, além do marcador CA19.9 em valores altos. Concluiu-se que havia uma massa tumoral em cólon direito que fistulizou para o duodeno. Efetuou-se, uma laparotomia, onde identificou um tumor irressecável em vias de obstrução do cólon, que invadia o duodeno. Foi optada pela realização de uma jejunotransverso anastomose, afim de manter o trânsito intestinal. DISCUSSÃO: As úlceras representam a principal causa de hemorragia digestiva alta (HDA), e possuem uma mortalidade elevada. Os fatores de risco que aumentam a mortalidade na HDA são idade maior de 60 anos; choque, instabilidade hemodinâmica; comorbidades; diagnósticos prévios de doenças do trato gastrointestinal; e ressangramento. As técnicas diagnósticas e terapêuticas podem ser endoscópicas, radiológicas ou cirúrgicas. CONCLUSÃO: O caso mostra que o motivo do sangramento não era uma etiologia comum para HDA, mas uma causa comum de hemorragia digestiva baixa, o câncer colorretal, a terceira neoplasia mais diagnosticada e uma das causas mais comuns de mortes oncológicas, sendo a colonoscopia o principal exame diagnóstico.

Published: December 2023

Micro-mineral profiles of feed and fodder, blood serum and hair of camels in 2 villages each from 2 Tehsils of Hanumangarh and Ganganagar districts of irrigated North-Western plain of arid Rajasthan were studied. The most of dry and green roughages and tree leaves were found deficient in Zinc. Crop residues contained copper at marginal level whereas tree leaves, green fodders and protein rich concentrate guar churi were found good source of Cu. Mn level in all feed stuffs were found adequate. Crop residues generally fed to camel contained adequate amount of Mn to meet requirement of camels. The all feed ingredients contained iron concentration in excess of requirement. Serum concentration of all trace minerals were within normal range. The blood serum Cu, Zn, Mn and Fe were well above than critical levels. The mean values of Zn observed in hair were lower than the normal values indicated inadequacy of its dietary supply. Mn in all hair samples was much higher than critical level <4.0 ppm. Cu level in hair was also marginal. Similar to feed and fodders and serum, iron concentration in hair was also much more than the normal minimum values. The study indicated that there is need of dietary supplementation of deficient minerals as area-specific mineral mixture for improving the productive and reproductive efficiency of camels of this region.

Published: December 2023

Solar energy is a renewable source of energy that does not emit greenhouse gases. The sun is free, inexhaustible and available all over the world. The sun's rays can be used to produce energy in two ways. The first technique converts the sun's rays into electricity using photovoltaic panels, while the second converts the sun's rays into heat using concentrated solar power plants (CSP). Several studies have been carried out with the aim of improving the performance of these solar power plants in order to achieve high efficiency, which is the case in our study. In this work a numerical study was carried out on the effect of nanoparticles on the thermophysical properties of nanofluids with the aim of determining the most optimal nanofluid for use as a heat transfer fluid in concentrated solar power plants. The nanoparticles examined were metal oxides (SIO2, MgO and Fe3O4), which were dispersed in Therminol VP-1 and Syltherm 800. The thermophysical properties examined were density, thermal conductivity and heat capacity. To carry out this study, we set the temperature from 200 to 400°C at the same operating temperature as the concentrating solar power plant.After evaluating the effect of nanoparticles on the thermophysical properties, we studied the behaviour of the CSP plant based on nanofluids using SAM (System Advisor Model) software.  The results obtained are very encouraging and show that the addition of nanoparticles to a base fluid improves its thermophysical properties compared with the pure base fluid, and the rate of improvement in thermal conductivity exceeds 9%. We also found that the nanofluid (Fe3O4 /Therminol Vp1) is the best selected for use as a heat transfer fluid in concentrated solar power plants with an efficiency and thermal energy produced equal to 40.87% and 588164 MWht, respectively.

Araştırmanın temel odak noktası, Mahsa Amini’nin ölümü sonrasında başlayan protestoların çevrimiçi yayın medyasından örneklem olarak seçilen cumhuriyet.com.tr, yenisafak.com ve milliyet.com.tr gazetelerinde yer alan haber metinlerindeki söylemi, hem yazılı hem de görsel unsurlar ile birlikte söylem analizine tabi tutmaktır. Bu analiz, Teun A. van Dijk tarafından yapılandırılan eleştirel söylem analizi metodu çerçevesinde yapılmıştır. Araştırma kapsamı, Mahsa Amini’nin ölümü ve protestoların başlangıç tarihi olan 16 Eylül 2022 ile 30 Kasım 2022 tarihleri arasındaki zaman dilimini kapsamaktadır. Gazetelerin internet sitelerindeki haberler, söylem analizi yöntemi ile incelenerek, olayların gazetelerde nasıl ele alındığı ortaya konulmaya çalışılmıştır. Araştırma sonuçlarına göre, www.cumhuriyet.com.tr, toplumsal cinsiyet ve kadın haklarına odaklanırken İran hükümetinin olumsuz tutumunu ele almıştır. www.yenisafak.com ise protestoların şiddetlendiğini, siyasi bir kriz yaşandığını, hükümet yanlısı bir kitlenin varlığını vurgulamış ve Mahsa Amini’nin ölümünü dini gerekçelerle meşrulaştırmıştır. www.milliyet.com.tr ise Mahsa Amini’nin ölümünün insan haklarına aykırı olduğunu vurgulamış ve protestoları İran’da toplumsal, siyasi ve kültürel bir çatışmanın bir yansıması olarak ele almıştır. Dolayısıyla, üç farklı gazete www.cumhuriyet.com.tr, www.yenisafak.com ve www.milliyet.com.tr, aynı protestoları ele alırken farklı haber sunumları gerçekleştirmişlerdir.

Small and medium-sized businesses (SMEs) are crucial for the growth of economies and the creation of jobs in most emerging nations. This study’s goal is to investigate and evaluate how innovations affect the development and competitiveness of SMEs in South Africa. Purposive sampling was used to identify the study participants. The study uses a quantitative research approach that enables the collection and analysis of numerical data from a sample size of 400 SME owners and managers. According to the study’s findings, SMEs that are innovative in their operations have a higher chance of surviving, expanding, and remaining competitive in the market than those that are not. It has been found that a variety of innovation-related factors, such as product innovation, process innovation, marketing innovation, and organisational innovation, have a considerable positive impact on the development and competitiveness of SMEs. The study suggests that governments, trade groups, and business support organisations should play a significant part in fostering an atmosphere that encourages innovation among SMEs.

La familia es un grupo organizado, con complejas relaciones, que tienen vínculos afectivos, valores, creencias, tradiciones y proyectos que definen sus estilos y formas de ser. Requerimos cambiar la idea de que existen familias disfuncionales, lo que hay son padres y madres que interactúan con sus hijos de maneras diferentes porque sus historias son diversas. Hay que mejorar las formas de compartir el tiempo con las hijas e hijos, buscar cómo darles ternura y amor, ser suaves en la forma, pero firmes en el fondo, confiar y creer en ellos. Así, los niños aprenderán de su familia actitudes, roles y saberes. De las cosas más valiosas por adquirir están las formas de comunicación y diálogo así como el modelaje de ser mamá y papá. Este libro pretende que los niños y niñas sepan que hay una gran diversidad de familias. La alfabetización emergente es el aprendizaje-enseñanza de la lectoescritura de 0 a 6 años de edad. En las vigentes investigaciones sudamericanas las y los preescolares saben leer y escribir en el nivel que les corresponde. Desde este enfoque, ellos escribirán una entrevista de manera divertida, usando las letras, similetras o grafismos desde su nivel de desarrollo de escritura. Leerán un libro-álbum y un poema para apreciar a su familia, así como juegos digitales y rimas. Y para terminar, construirán un rompecabezas.
